+Description:
+
+ The ftrace was first added to the kernel, its interface was placed
+ into the debugfs file system under the "tracing" directory. Access
+ to the files were in /sys/kernel/debug/tracing. As systems wanted
+ access to the tracing interface without having to enable debugfs, a
+ new interface was created called "tracefs". This was a stand alone
+ file system and was usually mounted in /sys/kernel/tracing.
+
+ To allow older tooling to continue to operate, when mounting
+ debugfs, the tracefs file system would automatically get mounted in
+ the "tracing" directory of debugfs. The tracefs interface was added
+ in January 2015 in the v4.1 kernel.
+
+ All tooling should now be using tracefs directly and the "tracing"
+ directory in debugfs should be removed by January 2030.

-Description:
- This directory exposes interfaces for interactive with
- EFI variables. For more information on EFI variables,
- see 'Variable Services' in the UEFI specification
- (section 7.2 in specification version 2.3 Errata D).
-
- In summary, EFI variables are named, and are classified
- into separate namespaces through the use of a vendor
- GUID. They also have an arbitrary binary value
- associated with them.
-
- The efivars module enumerates these variables and
- creates a separate directory for each one found. Each
- directory has a name of the form "<key>-<vendor guid>"
- and contains the following files:
-
- =============== ========================================
- attributes: A read-only text file enumerating the
- EFI variable flags. Potential values
- include:
-
- EFI_VARIABLE_NON_VOLATILE
- EFI_VARIABLE_BOOTSERVICE_ACCESS
- EFI_VARIABLE_RUNTIME_ACCESS
- EFI_VARIABLE_HARDWARE_ERROR_RECORD
- EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS
-
- See the EFI documentation for an
- explanation of each of these variables.
-
- data: A read-only binary file that can be read
- to attain the value of the EFI variable
-
- guid: The vendor GUID of the variable. This
- should always match the GUID in the
- variable's name.
-
- raw_var: A binary file that can be read to obtain
- a structure that contains everything
- there is to know about the variable.
- For structure definition see "struct
- efi_variable" in the kernel sources.
-
- This file can also be written to in
- order to update the value of a variable.
- For this to work however, all fields of
- the "struct efi_variable" passed must
- match byte for byte with the structure
- read out of the file, save for the value
- portion.
-
- **Note** the efi_variable structure
- read/written with this file contains a
- 'long' type that may change widths
- depending on your underlying
- architecture.
-
- size: As ASCII representation of the size of
- the variable's value.
- =============== ========================================
-
-
- In addition, two other magic binary files are provided
- in the top-level directory and are used for adding and
- removing variables:
-
- =============== ========================================
- new_var: Takes a "struct efi_variable" and
- instructs the EFI firmware to create a
- new variable.
-
- del_var: Takes a "struct efi_variable" and
- instructs the EFI firmware to remove any
- variable that has a matching vendor GUID
- and variable key name.

+Date: April, 2023
+KernelVersion: v6.4
+Contact: linux-cxl@vger.kernel.org
+Description:
+ (WO) When a Device Physical Address (DPA) is written to this
+ attribute, the memdev driver sends an inject poison command to
+ the device for the specified address. The DPA must be 64-byte
+ aligned and the length of the injected poison is 64-bytes. If
+ successful, the device returns poison when the address is
+ accessed through the CXL.mem bus. Injecting poison adds the
+ address to the device's Poison List and the error source is set
+ to Injected. In addition, the device adds a poison creation
+ event to its internal Informational Event log, updates the
+ Event Status register, and if configured, interrupts the host.
+ It is not an error to inject poison into an address that
+ already has poison present and no error is returned. If the
+ device returns 'Inject Poison Limit Reached' an -EBUSY error
+ is returned to the user. The inject_poison attribute is only
+ visible for devices supporting the capability.
+
+ TEST-ONLY INTERFACE: This interface is intended for testing
+ and validation purposes only. It is not a data repair mechanism
+ and should never be used on production systems or live data.
+
+ DATA LOSS RISK: For CXL persistent memory (PMEM) devices,
+ poison injection can result in permanent data loss. Injected
+ poison may render data permanently inaccessible even after
+ clearing, as the clear operation writes zeros and does not
+ recover original data.
+
+ SYSTEM STABILITY RISK: For volatile memory, poison injection
+ can cause kernel crashes, system instability, or unpredictable
+ behavior if the poisoned addresses are accessed by running code
+ or critical kernel structures.

+Description:
+ (WO) When a Device Physical Address (DPA) is written to this

+ the device for the specified address. Clearing poison removes
+ the address from the device's Poison List and writes 0 (zero)
+ for 64 bytes starting at address. It is not an error to clear
+ poison from an address that does not have poison set. If the
+ device cannot clear poison from the address, -ENXIO is returned.

+
+ CLEAR IS NOT DATA RECOVERY: This operation writes zeros to the

+Description: (WO) Write to inject an error that simulates an heartbeat
+ failure. This is to be used for testing purposes.
+
+ After writing this file, the driver stops arbitration on a
+ random engine and disables the fetching of heartbeat counters.
+ If a workload is running on the device, a job submitted to the
+ accelerator might not get a response and a read of the
+ `heartbeat/status` attribute might report -1, i.e. device
+ unresponsive.
+ The error is unrecoverable thus the device must be restarted to
+ restore its functionality.
+
+ This attribute is available only when the kernel is built with
+ CONFIG_CRYPTO_DEV_QAT_ERROR_INJECTION=y.
+
+ A write of 1 enables error injection.
+

+Description:
+ This attribute is used to enable the analog input multiplexer
+ auto-zeroing algorithm (the input multiplexer and the ADC
+ include an offset cancellation algorithm that cancels the offset
+ contribution of the ADC). When the offset cancellation algorithm
+ is enabled, ADC takes two conversions, one with the differential
+ input as VIN+/VIN-, one with VIN+/VIN- inverted. In this case the
+ conversion time is multiplied by two compared to the default
+ case where the algorithm is disabled. This technique allows the
+ cancellation of the ADC offset error and the achievement of
+ ultra-low offset without any digital calibration. The resulting
+ offset is the residue of the difference between the two
+ conversions, which is on the order of magnitude of the noise
+ floor. This offset is effectively canceled at every conversion,
+ so the residual offset error temperature drift is extremely low.
+ Write '1' to enable it, write '0' to disable it.

+Description:
+ This attribute is used to enable the chopping algorithm for the
+ internal voltage reference buffer. This setting has no effect
+ when external voltage reference is selected.
+ Internal voltage reference buffer injects a certain quantity of
+ 1/f noise into the system that can be modulated with the
+ incoming input signals and can limit the SNR performance at
+ higher Oversampling Ratio values (over 256). To overcome this
+ limitation, the buffer includes an auto-zeroing algorithm that
+ greatly reduces (cancels out) the 1/f noise and cancels the
+ offset value of the reference buffer. As a result, the SNR of
+ the system is not affected by this 1/f noise component of the
+ reference buffer, even at maximum oversampling ratio values.
+ Write '1' to enable it, write '0' to disable it.

+What: /sys/class/leds/*:enclosure:*/brightness
+Date: August 2024
+KernelVersion: 6.12
+Description:
+ LED indications on PCIe storage enclosures which are controlled
+ through the NPEM interface (Native PCIe Enclosure Management,
+ PCIe r6.1 sec 6.28) are accessible as led class devices, both
+ below /sys/class/leds and below NPEM-capable PCI devices.
+
+ Although these led class devices could be manipulated manually,
+ in practice they are typically manipulated automatically by an
+ application such as ledmon(8).
+
+ The name of a led class device is as follows:
+ <bdf>:enclosure:<indication>
+ where:
+
+ - <bdf> is the domain, bus, device and function number
+ (e.g. 10000:02:05.0)
+ - <indication> is a short description of the LED indication
+
+ Valid indications per PCIe r6.1 table 6-27 are:
+
+ - ok (drive is functioning normally)
+ - locate (drive is being identified by an admin)
+ - fail (drive is not functioning properly)
+ - rebuild (drive is part of an array that is rebuilding)
+ - pfa (drive is predicted to fail soon)
+ - hotspare (drive is marked to be used as a replacement)
+ - ica (drive is part of an array that is degraded)
+ - ifa (drive is part of an array that is failed)
+ - idt (drive is not the right type for the connector)
+ - disabled (drive is disabled, removal is safe)
+ - specific0 to specific7 (enclosure-specific indications)
+
+ Broadly, the indications fall into one of these categories:
+
+ - to signify drive state (ok, locate, fail, idt, disabled)
+ - to signify drive role or state in a software RAID array
+ (rebuild, pfa, hotspare, ica, ifa)
+ - to signify any other role or state (specific0 to specific7)
+
+ Mandatory indications per PCIe r6.1 sec 7.9.19.2 comprise:
+ ok, locate, fail, rebuild. All others are optional.
+ A led class device is only visible if the corresponding
+ indication is supported by the device.
+
+ To manipulate the indications, write 0 (LED_OFF) or 1 (LED_ON)
+ to the "brightness" file. Note that manipulating an indication
+ may implicitly manipulate other indications at the vendor's
+ discretion. E.g. when the user lights up the "ok" indication,
+ the vendor may choose to automatically turn off the "fail"
+ indication. The current state of an indication can be
+ retrieved by reading its "brightness" file.
+
+ The PCIe Base Specification allows vendors leeway to choose
+ different colors or blinking patterns for the indications,
+ but they typically follow the IBPI standard. E.g. the "locate"
+ indication is usually presented as one or two LEDs blinking at
+ 4 Hz frequency:
+ https://en.wikipedia.org/wiki/International_Blinking_Pattern_Interpretation
+
+ PCI Firmware Specification r3.3 sec 4.7 defines a DSM interface
+ to facilitate shared access by operating system and platform
+ firmware to a device's NPEM registers. The kernel will use
+ this DSM interface where available, instead of accessing NPEM
+ registers directly. The DSM interface does not support the
+ enclosure-specific indications "specific0" to "specific7",
+ hence the corresponding led class devices are unavailable if
+ the DSM interface is used.

+Description:
+ This directory contains a list of the supported Data Object
+ Exchange (DOE) features. The features are the file name.
+ The contents of each file is the raw Vendor ID and data
+ object feature values.
+
+ The value comes from the device and specifies the vendor and
+ data object type supported. The lower (RHS of the colon) is
+ the data object type in hex. The upper (LHS of the colon)
+ is the vendor ID.
+
+ As all DOE devices must support the DOE discovery feature,
+ if DOE is supported you will at least see the doe_discovery
+ file, with this contents:
+
+ # cat doe_features/doe_discovery
+ 0001:00
+
+ If the device supports other features you will see other
+ files as well. For example if CMA/SPDM and secure CMA/SPDM
+ are supported the doe_features directory will look like
+ this:
+
+ # ls doe_features
+ 0001:01 0001:02 doe_discovery

+ indicates that the platform TSM (TEE Security Manager) has made
+ a secure-session connection with a device's DSM. A DSM is always
+ physical function 0 and when the device supports TDISP (TEE
+ Device Interface Security Protocol) its managed functions also
+ populate this tsm/dsm attribute. The managed functions of a DSM
+ are SR-IOV (Single Root I/O Virtualization) virtual functions,
+ non-zero functions of a multi-function device, or downstream
+ endpoints depending on whether the DSM is an SR-IOV physical
+ function, function0 of a multi-function device, or an upstream

+Description: (RO) Return the device name of the TSM when the device is in a

+ (LOCKED, RUN, or ERROR, not UNLOCKED). Bound devices consume
+ platform TSM resources and depend on the device's configuration
+ (e.g. BME (Bus Master Enable) and MSE (Memory Space Enable)
+ among other settings) to remain stable for the duration of the
+ bound state. This attribute is only visible for devices that
+ support TDISP operation, and it is only populated after
+ successful connect and TSM bind. The TSM bind operation is
+ initiated by VFIO/IOMMUFD. This is a "link" TSM attribute, see
+ Documentation/ABI/testing/sysfs-class-tsm.
+
+What: /sys/bus/pci/devices/.../authenticated
+Contact: linux-pci@vger.kernel.org
+Description:
+ When the device's tsm/ directory is present device
+ authentication (PCIe CMA-SPDM) and link encryption (PCIe IDE)
+ are handled by the platform TSM (TEE Security Manager). When the
+ tsm/ directory is not present this attribute reflects only the
+ native CMA-SPDM authentication state with the kernel's
+ certificate store.
+
+ If the attribute is not present, it indicates that
+ authentication is unsupported by the device, or the TSM has no
+ available authentication methods for the device.
+
+ When present and the tsm/ attribute directory is present, the
+ authenticated attribute is an alias for the device 'connect'
+ state. See the 'tsm/connect' attribute for more details.

+ unlimited attributes.

+Common Files (Present in all feature directories):
+
+ caps
+ - Read-only
+ - Lists available capabilities for this feature.
+
+ guids
+ - Read-only
+ - Lists GUIDs associated with this feature.
+
+Additional Attributes (Conditional Presence):
+
+ max_command_size
+ - Read-only
+ - Present if the feature supports out-of-band MCTP access.
+ - Maximum supported MCTP command size for out-of-band PMT access (bytes).
+
+ max_stream_size
+ - Read-only
+ - Present if the feature supports out-of-band MCTP access.
+ - Maximum supported MCTP stream size (bytes).
+
+ min_watcher_period_ms
+ - Read-only
+ - Present if the feature supports the watcher API.
+ The watcher API provides a writable control interface that allows user
+ configuration of monitoring behavior, such as setting the sampling or
+ reporting interval.
+ - Minimum supported time period for the watcher interface (milliseconds).
+
+ num_rmids
+ - Read-only
+ - Present if the feature supports RMID (Resource Monitoring ID) telemetry.
+ RMIDs are identifiers used by hardware to track and report resource usage,
+ such as memory bandwidth or energy consumption, on a per-logical-entity
+ basis (e.g., per core, thread, or process group).
+ - Maximum number of RMIDs tracked simultaneously.
+
+Example:
+For a device with PCI BDF `0000:00:03.1`, the directory tree could look like:
+
+ /sys/class/intel_pmt/features-0000:00:03.1/

+
+Notes:
+ - Some attributes are only present if the corresponding feature supports
+ the capability (e.g., `max_command_size` for MCTP-capable features).
+ - Features supporting RMIDs include `num_rmids`.
+ - Features supporting the watcher API include `min_watcher_period_ms`.

+Description:
+ These interfaces under /sys/devices/platform/HISI04Bx/ are
+ used to support the low power consumption feature of some
+ HCCS types by changing the number of lanes used. The interfaces
+ changing the number of lanes used are 'dec_lane_of_type' and
+ 'inc_lane_of_type' which require root privileges. These
+ interfaces aren't exposed if no HCCS type on platform support
+ this feature. Please note that decreasing lane number is only
+ allowed if all the specified HCCS ports are not busy.
+
+ The low power consumption interfaces are as follows:
+
+ ============================= ==== ================================
+ available_inc_dec_lane_types: (RO) available HCCS types (string) to
+ increase and decrease the number
+ of lane used, e.g. HCCS-v2.
+ dec_lane_of_type: (WO) input HCCS type supported
+ decreasing lane to decrease the
+ used lane number of all specified
+ HCCS type ports on platform to
+ the minimum.
+ You can query the 'cur_lane_num'
+ to get the minimum lane number
+ after executing successfully.
+ inc_lane_of_type: (WO) input HCCS type supported
+ increasing lane to increase the
+ used lane number of all specified
+ HCCS type ports on platform to
+ the full lane state.

+Description:
+ This attribute is applicable to ufs devices compliant to the
+ JEDEC specifications version 4.1 or later. The
+ device_lvl_exception_count is a counter indicating the number of
+ times the device level exceptions have occurred since the last
+ time this variable is reset. Writing a 0 value to this
+ attribute will reset the device_lvl_exception_count. If the
+ device_lvl_exception_count reads a positive value, the user
+ application should read the device_lvl_exception_id attribute to
+ know more information about the exception.
+
+ The attribute is read/write.

-Date: February 2021

-Description: In host control mode, reads are the major source of activation
- trials. Once this threshold hs met, the region is added to the
- "to-be-activated" list. Since we reset the read counter upon
- write, this include sending a rb command updating the region
- ppn as well.

-Date: February 2021
-Contact: Avri Altman <avri.altman@wdc.com>
-Description: In host control mode, we think of the regions as "buckets".
- Those buckets are being filled with reads, and emptied on write.
- We use entries_per_srgn - the amount of blocks in a subregion as
- our bucket size. This applies because HPB1.0 only handles
- single-block reads. Once the bucket size is crossed, we trigger
- a normalization work - not only to avoid overflow, but mainly
- because we want to keep those counters normalized, as we are
- using those reads as a comparative score, to make various decisions.
- The normalization is dividing (shift right) the read counter by
- the normalization_factor. If during consecutive normalizations
- an active region has exhausted its reads - inactivate it.

-Description: Region deactivation is often due to the fact that eviction took
- place: A region becomes active at the expense of another. This is
- happening when the max-active-regions limit has been crossed.
- In host mode, eviction is considered an extreme measure. We
- want to verify that the entering region has enough reads, and
- the exiting region has much fewer reads. eviction_thld_enter is
- the min reads that a region must have in order to be considered
- a candidate for evicting another region.

-Description: In order not to hang on to "cold" regions, we inactivate
- a region that has no READ access for a predefined amount of
- time - read_timeout_ms. If read_timeout_ms has expired, and the
- region is dirty, it is less likely that we can make any use of
- HPB reading it so we inactivate it. Still, deactivation has
- its overhead, and we may still benefit from HPB reading this
- region if it is clean - see read_timeout_expiries.

+
+ In auto mode, all node weights are re-calculated and overwritten

+ is made available during either boot or hotplug events.
+
+ In manual mode, node weights can only be updated by the user.

+ will reuse those weights. If they were not previously set or
+ are onlined with missing bandwidth data, the weights will use
+ a default weight of 1.

+ mode, while writing any false value string (e.g. N or 0) will
+ enable manual mode. All other strings are ignored and will

+ Writing a new weight to a node directly via the nodeN interface

+Description:
+ The "cells" folder contains one file per cell exposed by the
+ NVMEM device. The name of the file is: "<name>@<byte>,<bit>",
+ with <name> being the cell name and <where> its location in
+ the NVMEM device, in hexadecimal bytes and bits (without the
+ '0x' prefix, to mimic device tree node names). The length of
+ the file is the size of the cell (when known). The content of
+ the file is the binary content of the cell (may sometimes be
+ ASCII, likely without trailing character).
+ Note: This file is only present if CONFIG_NVMEM_SYSFS
+ is enabled.
+
+ Example::
+
+ hexdump -C /sys/bus/nvmem/devices/1-00563/cells/product-name@d,0

-Description:
- Various files for managing Cable Based Association of
- (wireless) USB devices.
-
- The sequence of operations should be:
-
- 1. Device is plugged in.
-
- 2. The connection manager (CM) sees a device with CBA capability.
- (the wusb_chid etc. files in /sys/devices/blah/OURDEVICE).
-
- 3. The CM writes the host name, supported band groups,
- and the CHID (host ID) into the wusb_host_name,
- wusb_host_band_groups and wusb_chid files. These
- get sent to the device and the CDID (if any) for
- this host is requested.
-
- 4. The CM can verify that the device's supported band
- groups (wusb_device_band_groups) are compatible
- with the host.
-
- 5. The CM reads the wusb_cdid file.
-
- 6. The CM looks it up its database.
-
- - If it has a matching CHID,CDID entry, the device
- has been authorized before and nothing further
- needs to be done.
-
- - If the CDID is zero (or the CM doesn't find a
- matching CDID in its database), the device is
- assumed to be not known. The CM may associate
- the host with device by: writing a randomly
- generated CDID to wusb_cdid and then a random CK
- to wusb_ck (this uploads the new CC to the
- device).
-
- CMD may choose to prompt the user before
- associating with a new device.
-
- 7. Device is unplugged.

+Firmware of PCIe controller for Renesas R-Car V4H
+=================================================
+
+Renesas R-Car V4H (r8a779g0) has a PCIe controller, requiring a specific
+firmware download during startup.
+
+However, Renesas currently cannot distribute the firmware free of charge.
+
+The firmware file "104_PCIe_fw_addr_data_ver1.05.txt" (note that the file name
+might be different between different datasheet revisions) can be found in the
+datasheet encoded as text, and as such, the file's content must be converted
+back to binary form. This can be achieved using the following example script:
+
+.. code-block:: sh
+
+ $ awk '/^\s*0x[0-9A-Fa-f]{4}\s+0x[0-9A-Fa-f]{4}/ { print substr($2,5,2) substr($2,3,2) }' \
+ 104_PCIe_fw_addr_data_ver1.05.txt | \
+ xxd -p -r > rcar_gen4_pcie.bin
+
+Once the text content has been converted into a binary firmware file, verify
+its checksum as follows:
+
+.. code-block:: sh
+
+ $ sha1sum rcar_gen4_pcie.bin
+ 1d0bd4b189b4eb009f5d564b1f93a79112994945 rcar_gen4_pcie.bin
+
+The resulting binary file called "rcar_gen4_pcie.bin" should be placed in the
+"/lib/firmware" directory before the driver runs.

+Overview
+========
+
+TPH (TLP Processing Hints) is a PCIe feature that allows endpoint devices
+to provide optimization hints for requests that target memory space.
+These hints, in a format called Steering Tags (STs), are embedded in the
+requester's TLP headers, enabling the system hardware, such as the Root
+Complex, to better manage platform resources for these requests.
+
+For example, on platforms with TPH-based direct data cache injection
+support, an endpoint device can include appropriate STs in its DMA
+traffic to specify which cache the data should be written to. This allows
+the CPU core to have a higher probability of getting data from cache,
+potentially improving performance and reducing latency in data
+processing.
+
+
+How to Use TPH
+==============
+
+TPH is presented as an optional extended capability in PCIe. The Linux
+kernel handles TPH discovery during boot, but it is up to the device
+driver to request TPH enablement if it is to be utilized. Once enabled,
+the driver uses the provided API to obtain the Steering Tag for the
+target memory and to program the ST into the device's ST table.
+
+Enable TPH support in Linux
+---------------------------
+
+To support TPH, the kernel must be built with the CONFIG_PCIE_TPH option
+enabled.
+
+Manage TPH
+----------
+
+To enable TPH for a device, use the following function::
+
+ int pcie_enable_tph(struct pci_dev *pdev, int mode);
+
+This function enables TPH support for device with a specific ST mode.
+Current supported modes include:
+
+ * PCI_TPH_ST_NS_MODE - NO ST Mode
+ * PCI_TPH_ST_IV_MODE - Interrupt Vector Mode
+ * PCI_TPH_ST_DS_MODE - Device Specific Mode
+
+`pcie_enable_tph()` checks whether the requested mode is actually
+supported by the device before enabling. The device driver can figure out
+which TPH mode is supported and can be properly enabled based on the
+return value of `pcie_enable_tph()`.
+
+To disable TPH, use the following function::
+
+ void pcie_disable_tph(struct pci_dev *pdev);
+
+Manage ST
+---------
+
+Steering Tags are platform specific. PCIe spec does not specify where STs
+are from. Instead PCI Firmware Specification defines an ACPI _DSM method
+(see the `Revised _DSM for Cache Locality TPH Features ECN
+<https://members.pcisig.com/wg/PCI-SIG/document/15470>`_) for retrieving
+STs for a target memory of various properties. This method is what is
+supported in this implementation.
+
+To retrieve a Steering Tag for a target memory associated with a specific
+CPU, use the following function::
+
+ int pcie_tph_get_cpu_st(struct pci_dev *pdev, enum tph_mem_type type,
+ unsigned int cpu_uid, u16 *tag);
+
+The `type` argument is used to specify the memory type, either volatile
+or persistent, of the target memory. The `cpu_uid` argument specifies the
+CPU where the memory is associated to.
+
+After the ST value is retrieved, the device driver can use the following
+function to write the ST into the device::
+
+ int pcie_tph_set_st_entry(struct pci_dev *pdev, unsigned int index,
+ u16 tag);
+
+The `index` argument is the ST table entry index the ST tag will be
+written into. `pcie_tph_set_st_entry()` will figure out the proper
+location of ST table, either in the MSI-X table or in the TPH Extended
+Capability space, and write the Steering Tag into the ST entry pointed by
+the `index` argument.
+
+It is completely up to the driver to decide how to use these TPH
+functions. For example a network device driver can use the TPH APIs above
+to update the Steering Tag when interrupt affinity of a RX/TX queue has
+been changed. Here is a sample code for IRQ affinity notifier:
+
+.. code-block:: c
+
+ static void irq_affinity_notified(struct irq_affinity_notify *notify,
+ const cpumask_t *mask)
+ {
+ struct drv_irq *irq;
+ unsigned int cpu_id;
+ u16 tag;
+
+ irq = container_of(notify, struct drv_irq, affinity_notify);
+ cpumask_copy(irq->cpu_mask, mask);
+
+ /* Pick a right CPU as the target - here is just an example */
+ cpu_id = cpumask_first(irq->cpu_mask);
+
+ if (pcie_tph_get_cpu_st(irq->pdev, TPH_MEM_TYPE_VM, cpu_id,
+ &tag))
+ return;
+
+ if (pcie_tph_set_st_entry(irq->pdev, irq->msix_nr, tag))
+ return;
+ }
+
+Disable TPH system-wide
+-----------------------
+
+There is a kernel command line option available to control TPH feature:
+ * "notph": TPH will be disabled for all endpoint devices.

+Concurrent Quiescent State Reporting for Offline CPUs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+RCU must ensure that CPUs going offline report quiescent states to avoid
+blocking grace periods. This requires careful synchronization to handle
+race conditions
+
+Race condition causing Offline CPU to hang GP
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+A race between CPU offlining and new GP initialization (gp_init()) may occur
+because rcu_report_qs_rnp() in rcutree_report_cpu_dead() must temporarily
+release the ``rcu_node`` lock to wake the RCU grace-period kthread::
+
+ CPU1 (going offline) CPU0 (GP kthread)
+ -------------------- -----------------
+ rcutree_report_cpu_dead()
+ rcu_report_qs_rnp()
+ // Must release rnp->lock to wake GP kthread
+ raw_spin_unlock_irqrestore_rcu_node()
+ // Wakes up and starts new GP
+ rcu_gp_init()
+ // First loop:
+ copies qsmaskinitnext->qsmaskinit
+ // CPU1 still in qsmaskinitnext!
+
+ // Second loop:
+ rnp->qsmask = rnp->qsmaskinit
+ mask = rnp->qsmask & ~rnp->qsmaskinitnext
+ // mask is 0! CPU1 still in both masks
+ // Reacquire lock (but too late)
+ rnp->qsmaskinitnext &= ~mask // Finally clears bit
+
+Without ``ofl_lock``, the new grace period includes the offline CPU and waits
+forever for its quiescent state causing a GP hang.
+
+A solution with ofl_lock
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+The ``ofl_lock`` (offline lock) prevents rcu_gp_init() from running during
+the vulnerable window when rcu_report_qs_rnp() has released ``rnp->lock``::
+
+ CPU0 (rcu_gp_init) CPU1 (rcutree_report_cpu_dead)
+ ------------------ ------------------------------
+ rcu_for_each_leaf_node(rnp) {
+ arch_spin_lock(&ofl_lock) -----> arch_spin_lock(&ofl_lock) [BLOCKED]
+
+ // Safe: CPU1 can't interfere
+ rnp->qsmaskinit = rnp->qsmaskinitnext
+
+ arch_spin_unlock(&ofl_lock) ---> // Now CPU1 can proceed
+ } // But snapshot already taken
+
+Another race causing GP hangs in rcu_gpu_init(): Reporting QS for Now-offline CPUs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+After the first loop takes an atomic snapshot of online CPUs, as shown above,
+the second loop in rcu_gp_init() detects CPUs that went offline between
+releasing ``ofl_lock`` and acquiring the per-node ``rnp->lock``.
+This detection is crucial because:

PROPER CARE AND FEEDING OF RETURN VALUES FROM rcu_dereference()
===============================================================
-Most of the time, you can use values from rcu_dereference() or one of

+Proper care and feeding of address and data dependencies is critically
+important to correct use of things like RCU. To this end, the pointers
+returned from the rcu_dereference() family of primitives carry address and
+data dependencies. These dependencies extend from the rcu_dereference()
+macro's load of the pointer to the later use of that pointer to compute
+either the address of a later memory access (representing an address
+dependency) or the value written by a later memory access (representing

+
+Overview
+========
+
+AMD NPU (Neural Processing Unit) is a multi-user AI inference accelerator
+integrated into AMD client APU. NPU enables efficient execution of Machine
+Learning applications like CNN, LLM, etc. NPU is based on
+`AMD XDNA Architecture`_. NPU is managed by **amdxdna** driver.
+
+
+Hardware Description
+====================
+
+AMD NPU consists of the following hardware components:
+
+AMD XDNA Array
+--------------
+
+AMD XDNA Array comprises of 2D array of compute and memory tiles built with
+`AMD AI Engine Technology`_. Each column has 4 rows of compute tiles and 1
+row of memory tile. Each compute tile contains a VLIW processor with its own
+dedicated program and data memory. The memory tile acts as L2 memory. The 2D
+array can be partitioned at a column boundary creating a spatially isolated
+partition which can be bound to a workload context.
+
+Each column also has dedicated DMA engines to move data between host DDR and
+memory tile.
+
+AMD Phoenix and AMD Hawk Point client NPU have a 4x5 topology, i.e., 4 rows of
+compute tiles arranged into 5 columns. AMD Strix Point client APU have 4x8
+topology, i.e., 4 rows of compute tiles arranged into 8 columns.
+
+Shared L2 Memory
+----------------
+
+The single row of memory tiles create a pool of software managed on chip L2
+memory. DMA engines are used to move data between host DDR and memory tiles.
+AMD Phoenix and AMD Hawk Point NPUs have a total of 2560 KB of L2 memory.
+AMD Strix Point NPU has a total of 4096 KB of L2 memory.
+
+Microcontroller
+---------------
+
+A microcontroller runs NPU Firmware which is responsible for command processing,
+XDNA Array partition setup, XDNA Array configuration, workload context
+management and workload orchestration.
+
+NPU Firmware uses a dedicated instance of an isolated non-privileged context
+called ERT to service each workload context. ERT is also used to execute user
+provided ``ctrlcode`` associated with the workload context.
+
+NPU Firmware uses a single isolated privileged context called MERT to service
+management commands from the amdxdna driver.
+
+Mailboxes
+---------
+
+The microcontroller and amdxdna driver use a privileged channel for management
+tasks like setting up of contexts, telemetry, query, error handling, setting up
+user channel, etc. As mentioned before, privileged channel requests are
+serviced by MERT. The privileged channel is bound to a single mailbox.
+
+The microcontroller and amdxdna driver use a dedicated user channel per
+workload context. The user channel is primarily used for submitting work to
+the NPU. As mentioned before, a user channel requests are serviced by an
+instance of ERT. Each user channel is bound to its own dedicated mailbox.
+
+PCIe EP
+-------
+
+NPU is visible to the x86 host CPU as a PCIe device with multiple BARs and some
+MSI-X interrupt vectors. NPU uses a dedicated high bandwidth SoC level fabric
+for reading or writing into host memory. Each instance of ERT gets its own
+dedicated MSI-X interrupt. MERT gets a single instance of MSI-X interrupt.
+
+The number of PCIe BARs varies depending on the specific device. Based on their
+functions, PCIe BARs can generally be categorized into the following types.
+
+* PSP BAR: Expose the AMD PSP (Platform Security Processor) function
+* SMU BAR: Expose the AMD SMU (System Management Unit) function
+* SRAM BAR: Expose ring buffers for the mailbox
+* Mailbox BAR: Expose the mailbox control registers (head, tail and ISR
+ registers etc.)
+* Public Register BAR: Expose public registers
+
+On specific devices, the above-mentioned BAR type might be combined into a
+single physical PCIe BAR. Or a module might require two physical PCIe BARs to
+be fully functional. For example,
+
+* On AMD Phoenix device, PSP, SMU, Public Register BARs are on PCIe BAR index 0.
+* On AMD Strix Point device, Mailbox and Public Register BARs are on PCIe BAR
+ index 0. The PSP has some registers in PCIe BAR index 0 (Public Register BAR)
+ and PCIe BAR index 4 (PSP BAR).
+
+Process Isolation Hardware
+--------------------------
+
+As explained before, XDNA Array can be dynamically divided into isolated
+spatial partitions, each of which may have one or more columns. The spatial
+partition is setup by programming the column isolation registers by the
+microcontroller. Each spatial partition is associated with a PASID which is
+also programmed by the microcontroller. Hence multiple spatial partitions in
+the NPU can make concurrent host access protected by PASID.
+
+The NPU FW itself uses microcontroller MMU enforced isolated contexts for
+servicing user and privileged channel requests.
+
+
+Mixed Spatial and Temporal Scheduling
+=====================================
+
+AMD XDNA architecture supports mixed spatial and temporal (time sharing)
+scheduling of 2D array. This means that spatial partitions may be setup and
+torn down dynamically to accommodate various workloads. A *spatial* partition
+may be *exclusively* bound to one workload context while another partition may
+be *temporarily* bound to more than one workload contexts. The microcontroller
+updates the PASID for a temporarily shared partition to match the context that
+has been bound to the partition at any moment.
+
+Resource Solver
+---------------
+
+The Resource Solver component of the amdxdna driver manages the allocation
+of 2D array among various workloads. Every workload describes the number
+of columns required to run the NPU binary in its metadata. The Resource Solver
+component uses hints passed by the workload and its own heuristics to
+decide 2D array (re)partition strategy and mapping of workloads for spatial and
+temporal sharing of columns. The FW enforces the context-to-column(s) resource
+binding decisions made by the Resource Solver.
+
+AMD Phoenix and AMD Hawk Point client NPU can support 6 concurrent workload
+contexts. AMD Strix Point can support 16 concurrent workload contexts.
+
+
+Application Binaries
+====================
+
+A NPU application workload is comprised of two separate binaries which are
+generated by the NPU compiler.
+
+1. AMD XDNA Array overlay, which is used to configure a NPU spatial partition.
+ The overlay contains instructions for setting up the stream switch
+ configuration and ELF for the compute tiles. The overlay is loaded on the
+ spatial partition bound to the workload by the associated ERT instance.
+ Refer to the
+ `Versal Adaptive SoC AIE-ML Architecture Manual (AM020)`_ for more details.
+
+2. ``ctrlcode``, used for orchestrating the overlay loaded on the spatial
+ partition. ``ctrlcode`` is executed by the ERT running in protected mode on
+ the microcontroller in the context of the workload. ``ctrlcode`` is made up
+ of a sequence of opcodes named ``XAie_TxnOpcode``. Refer to the
+ `AI Engine Run Time`_ for more details.
+
+
+Special Host Buffers
+====================
+
+Per-context Instruction Buffer
+------------------------------
+
+Every workload context uses a host resident 64 MB buffer which is memory
+mapped into the ERT instance created to service the workload. The ``ctrlcode``
+used by the workload is copied into this special memory. This buffer is
+protected by PASID like all other input/output buffers used by that workload.
+Instruction buffer is also mapped into the user space of the workload.
+
+Global Privileged Buffer
+------------------------
+
+In addition, the driver also allocates a single buffer for maintenance tasks
+like recording errors from MERT. This global buffer uses the global IOMMU
+domain and is only accessible by MERT.
+
+
+High-level Use Flow
+===================
+
+Here are the steps to run a workload on AMD NPU:
+
+1. Compile the workload into an overlay and a ``ctrlcode`` binary.
+2. Userspace opens a context in the driver and provides the overlay.
+3. The driver checks with the Resource Solver for provisioning a set of columns
+ for the workload.
+4. The driver then asks MERT to create a context on the device with the desired
+ columns.
+5. MERT then creates an instance of ERT. MERT also maps the Instruction Buffer
+ into ERT memory.
+6. The userspace then copies the ``ctrlcode`` to the Instruction Buffer.
+7. Userspace then creates a command buffer with pointers to input, output, and
+ instruction buffer; it then submits command buffer with the driver and goes
+ to sleep waiting for completion.
+8. The driver sends the command over the Mailbox to ERT.
+9. ERT *executes* the ``ctrlcode`` in the instruction buffer.
+10. Execution of the ``ctrlcode`` kicks off DMAs to and from the host DDR while
+ AMD XDNA Array is running.
+11. When ERT reaches end of ``ctrlcode``, it raises an MSI-X to send completion
+ signal to the driver which then wakes up the waiting workload.
+
+
+Boot Flow
+=========
+
+amdxdna driver uses PSP to securely load signed NPU FW and kick off the boot
+of the NPU microcontroller. amdxdna driver then waits for the alive signal in
+a special location on BAR 0. The NPU is switched off during SoC suspend and
+turned on after resume where the NPU FW is reloaded, and the handshake is
+performed again.
+
+
+Userspace components
+====================
+
+Compiler
+--------
+
+Peano is an LLVM based open-source single core compiler for AMD XDNA Array
+compute tile. Peano is available at:
+https://github.com/Xilinx/llvm-aie
+
+IRON is an open-source array compiler for AMD XDNA Array based NPU which uses
+Peano underneath. IRON is available at:
+https://github.com/Xilinx/mlir-aie
+
+Usermode Driver (UMD)
+---------------------
+
+The open-source XRT runtime stack interfaces with amdxdna kernel driver. XRT
+can be found at:
+https://github.com/Xilinx/XRT
+
+The open-source XRT shim for NPU is can be found at:
+https://github.com/amd/xdna-driver
+
+
+DMA Operation
+=============
+
+DMA operation instructions are encoded in the ``ctrlcode`` as
+``XAIE_IO_BLOCKWRITE`` opcode. When ERT executes ``XAIE_IO_BLOCKWRITE``, DMA
+operations between host DDR and L2 memory are effected.
+
+
+Error Handling
+==============
+
+When MERT detects an error in AMD XDNA Array, it pauses execution for that
+workload context and sends an asynchronous message to the driver over the
+privileged channel. The driver then sends a buffer pointer to MERT to capture
+the register states for the partition bound to faulting workload context. The
+driver then decodes the error by reading the contents of the buffer pointer.
+
+
+Telemetry
+=========
+
+MERT can report various kinds of telemetry information like the following:
+
+* L1 interrupt counter
+* DMA counter
+* Deep Sleep counter
+* etc.

+ Qualcomm Cloud AI 100 (AIC100)
+===============================
+
+Overview
+========
+
+The Qualcomm Cloud AI 100/AIC100 family of products (including SA9000P - part of
+Snapdragon Ride) are PCIe adapter cards which contain a dedicated SoC ASIC for
+the purpose of efficiently running Artificial Intelligence (AI) Deep Learning
+inference workloads. They are AI accelerators.
+
+The PCIe interface of AIC100 is capable of PCIe Gen4 speeds over eight lanes
+(x8). An individual SoC on a card can have up to 16 NSPs for running workloads.
+Each SoC has an A53 management CPU. On card, there can be up to 32 GB of DDR.
+
+Multiple AIC100 cards can be hosted in a single system to scale overall
+performance. AIC100 cards are multi-user capable and able to execute workloads
+from multiple users in a concurrent manner.
+
+Hardware Description
+====================
+
+An AIC100 card consists of an AIC100 SoC, on-card DDR, and a set of misc
+peripherals (PMICs, etc).
+
+An AIC100 card can either be a PCIe HHHL form factor (a traditional PCIe card),
+or a Dual M.2 card. Both use PCIe to connect to the host system.
+
+As a PCIe endpoint/adapter, AIC100 uses the standard VendorID(VID)/
+DeviceID(DID) combination to uniquely identify itself to the host. AIC100
+uses the standard Qualcomm VID (0x17cb). All AIC100 SKUs use the same
+AIC100 DID (0xa100).
+
+AIC100 does not implement FLR (function level reset).
+
+AIC100 implements MSI but does not implement MSI-X. AIC100 prefers 17 MSIs to
+operate (1 for MHI, 16 for the DMA Bridge). Falling back to 1 MSI is possible in
+scenarios where reserving 32 MSIs isn't feasible.
+
+As a PCIe device, AIC100 utilizes BARs to provide host interfaces to the device
+hardware. AIC100 provides 3, 64-bit BARs.
+
+* The first BAR is 4K in size, and exposes the MHI interface to the host.
+
+* The second BAR is 2M in size, and exposes the DMA Bridge interface to the
+ host.
+
+* The third BAR is variable in size based on an individual AIC100's
+ configuration, but defaults to 64K. This BAR currently has no purpose.
+
+From the host perspective, AIC100 has several key hardware components -
+
+* MHI (Modem Host Interface)
+* QSM (QAIC Service Manager)
+* NSPs (Neural Signal Processor)
+* DMA Bridge
+* DDR
+
+MHI
+---
+
+AIC100 has one MHI interface over PCIe. MHI itself is documented at
+Documentation/mhi/index.rst MHI is the mechanism the host uses to communicate
+with the QSM. Except for workload data via the DMA Bridge, all interaction with
+the device occurs via MHI.
+
+QSM
+---
+
+QAIC Service Manager. This is an ARM A53 CPU that runs the primary
+firmware of the card and performs on-card management tasks. It also
+communicates with the host via MHI. Each AIC100 has one of
+these.
+
+NSP
+---
+
+Neural Signal Processor. Each AIC100 has up to 16 of these. These are
+the processors that run the workloads on AIC100. Each NSP is a Qualcomm Hexagon
+(Q6) DSP with HVX and HMX. Each NSP can only run one workload at a time, but
+multiple NSPs may be assigned to a single workload. Since each NSP can only run
+one workload, AIC100 is limited to 16 concurrent workloads. Workload
+"scheduling" is under the purview of the host. AIC100 does not automatically
+timeslice.
+
+DMA Bridge
+----------
+
+The DMA Bridge is custom DMA engine that manages the flow of data
+in and out of workloads. AIC100 has one of these. The DMA Bridge has 16
+channels, each consisting of a set of request/response FIFOs. Each active
+workload is assigned a single DMA Bridge channel. The DMA Bridge exposes
+hardware registers to manage the FIFOs (head/tail pointers), but requires host
+memory to store the FIFOs.
+
+DDR
+---
+
+AIC100 has on-card DDR. In total, an AIC100 can have up to 32 GB of DDR.
+This DDR is used to store workloads, data for the workloads, and is used by the
+QSM for managing the device. NSPs are granted access to sections of the DDR by
+the QSM. The host does not have direct access to the DDR, and must make
+requests to the QSM to transfer data to the DDR.
+
+High-level Use Flow
+===================
+
+AIC100 is a multi-user, programmable accelerator typically used for running
+neural networks in inferencing mode to efficiently perform AI operations.
+AIC100 is not intended for training neural networks. AIC100 can be utilized
+for generic compute workloads.
+
+Assuming a user wants to utilize AIC100, they would follow these steps:
+
+1. Compile the workload into an ELF targeting the NSP(s)
+2. Make requests to the QSM to load the workload and related artifacts into the
+ device DDR
+3. Make a request to the QSM to activate the workload onto a set of idle NSPs
+4. Make requests to the DMA Bridge to send input data to the workload to be
+ processed, and other requests to receive processed output data from the
+ workload.
+5. Once the workload is no longer required, make a request to the QSM to
+ deactivate the workload, thus putting the NSPs back into an idle state.
+6. Once the workload and related artifacts are no longer needed for future
+ sessions, make requests to the QSM to unload the data from DDR. This frees
+ the DDR to be used by other users.
+
+
+Boot Flow
+=========
+
+AIC100 uses a flashless boot flow, derived from Qualcomm MSMs.
+
+When AIC100 is first powered on, it begins executing PBL (Primary Bootloader)
+from ROM. PBL enumerates the PCIe link, and initializes the BHI (Boot Host
+Interface) component of MHI.
+
+Using BHI, the host points PBL to the location of the SBL (Secondary Bootloader)
+image. The PBL pulls the image from the host, validates it, and begins
+execution of SBL.
+
+SBL initializes MHI, and uses MHI to notify the host that the device has entered
+the SBL stage. SBL performs a number of operations:
+
+* SBL initializes the majority of hardware (anything PBL left uninitialized),
+ including DDR.
+* SBL offloads the bootlog to the host.
+* SBL synchronizes timestamps with the host for future logging.
+* SBL uses the Sahara protocol to obtain the runtime firmware images from the
+ host.
+
+Once SBL has obtained and validated the runtime firmware, it brings the NSPs out
+of reset, and jumps into the QSM.
+
+The QSM uses MHI to notify the host that the device has entered the QSM stage
+(AMSS in MHI terms). At this point, the AIC100 device is fully functional, and
+ready to process workloads.

+DMA Bridge
+==========
+
+Overview
+--------
+
+The DMA Bridge is one of the main interfaces to the host from the device
+(the other being MHI). As part of activating a workload to run on NSPs, the QSM
+assigns that network a DMA Bridge channel. A workload's DMA Bridge channel
+(DBC for short) is solely for the use of that workload and is not shared with
+other workloads.
+
+Each DBC is a pair of FIFOs that manage data in and out of the workload. One
+FIFO is the request FIFO. The other FIFO is the response FIFO.
+
+Each DBC contains 4 registers in hardware:
+
+* Request FIFO head pointer (offset 0x0). Read only by the host. Indicates the
+ latest item in the FIFO the device has consumed.
+* Request FIFO tail pointer (offset 0x4). Read/write by the host. Host
+ increments this register to add new items to the FIFO.
+* Response FIFO head pointer (offset 0x8). Read/write by the host. Indicates
+ the latest item in the FIFO the host has consumed.
+* Response FIFO tail pointer (offset 0xc). Read only by the host. Device
+ increments this register to add new items to the FIFO.
+
+The values in each register are indexes in the FIFO. To get the location of the
+FIFO element pointed to by the register: FIFO base address + register * element
+size.
+
+DBC registers are exposed to the host via the second BAR. Each DBC consumes
+4KB of space in the BAR.
+
+The actual FIFOs are backed by host memory. When sending a request to the QSM
+to activate a network, the host must donate memory to be used for the FIFOs.
+Due to internal mapping limitations of the device, a single contiguous chunk of
+memory must be provided per DBC, which hosts both FIFOs. The request FIFO will
+consume the beginning of the memory chunk, and the response FIFO will consume
+the end of the memory chunk.
+
+Request FIFO
+------------
+
+A request FIFO element has the following structure:
+
+.. code-block:: c
+
+ struct request_elem {
+ u16 req_id;
+ u8 seq_id;
+ u8 pcie_dma_cmd;
+ u32 reserved;
+ u64 pcie_dma_source_addr;
+ u64 pcie_dma_dest_addr;
+ u32 pcie_dma_len;
+ u32 reserved;
+ u64 doorbell_addr;
+ u8 doorbell_attr;
+ u8 reserved;
+ u16 reserved;
+ u32 doorbell_data;
+ u32 sem_cmd0;
+ u32 sem_cmd1;
+ u32 sem_cmd2;
+ u32 sem_cmd3;
+ };
+
+Request field descriptions:
+
+req_id
+ request ID. A request FIFO element and a response FIFO element with
+ the same request ID refer to the same command.
+
+seq_id
+ sequence ID within a request. Ignored by the DMA Bridge.
+
+pcie_dma_cmd
+ describes the DMA element of this request.
+
+ * Bit(7) is the force msi flag, which overrides the DMA Bridge MSI logic
+ and generates a MSI when this request is complete, and QSM
+ configures the DMA Bridge to look at this bit.
+ * Bits(6:5) are reserved.
+ * Bit(4) is the completion code flag, and indicates that the DMA Bridge
+ shall generate a response FIFO element when this request is
+ complete.
+ * Bit(3) indicates if this request is a linked list transfer(0) or a bulk
+ transfer(1).
+ * Bit(2) is reserved.
+ * Bits(1:0) indicate the type of transfer. No transfer(0), to device(1),
+ from device(2). Value 3 is illegal.
+
+pcie_dma_source_addr
+ source address for a bulk transfer, or the address of the linked list.
+
+pcie_dma_dest_addr
+ destination address for a bulk transfer.
+
+pcie_dma_len
+ length of the bulk transfer. Note that the size of this field
+ limits transfers to 4G in size.
+
+doorbell_addr
+ address of the doorbell to ring when this request is complete.
+
+doorbell_attr
+ doorbell attributes.
+
+ * Bit(7) indicates if a write to a doorbell is to occur.
+ * Bits(6:2) are reserved.
+ * Bits(1:0) contain the encoding of the doorbell length. 0 is 32-bit,
+ 1 is 16-bit, 2 is 8-bit, 3 is reserved. The doorbell address
+ must be naturally aligned to the specified length.
+
+doorbell_data
+ data to write to the doorbell. Only the bits corresponding to
+ the doorbell length are valid.
+
+sem_cmdN
+ semaphore command.
+
+ * Bit(31) indicates this semaphore command is enabled.
+ * Bit(30) is the to-device DMA fence. Block this request until all
+ to-device DMA transfers are complete.
+ * Bit(29) is the from-device DMA fence. Block this request until all
+ from-device DMA transfers are complete.
+ * Bits(28:27) are reserved.
+ * Bits(26:24) are the semaphore command. 0 is NOP. 1 is init with the
+ specified value. 2 is increment. 3 is decrement. 4 is wait
+ until the semaphore is equal to the specified value. 5 is wait
+ until the semaphore is greater or equal to the specified value.
+ 6 is "P", wait until semaphore is greater than 0, then
+ decrement by 1. 7 is reserved.
+ * Bit(23) is reserved.
+ * Bit(22) is the semaphore sync. 0 is post sync, which means that the
+ semaphore operation is done after the DMA transfer. 1 is
+ presync, which gates the DMA transfer. Only one presync is
+ allowed per request.
+ * Bit(21) is reserved.
+ * Bits(20:16) is the index of the semaphore to operate on.
+ * Bits(15:12) are reserved.
+ * Bits(11:0) are the semaphore value to use in operations.
+
+Overall, a request is processed in 4 steps:
+
+1. If specified, the presync semaphore condition must be true
+2. If enabled, the DMA transfer occurs
+3. If specified, the postsync semaphore conditions must be true
+4. If enabled, the doorbell is written
+
+By using the semaphores in conjunction with the workload running on the NSPs,
+the data pipeline can be synchronized such that the host can queue multiple
+requests of data for the workload to process, but the DMA Bridge will only copy
+the data into the memory of the workload when the workload is ready to process
+the next input.
+
+Response FIFO
+-------------
+
+Once a request is fully processed, a response FIFO element is generated if
+specified in pcie_dma_cmd. The structure of a response FIFO element:
+
+.. code-block:: c
+
+ struct response_elem {
+ u16 req_id;
+ u16 completion_code;
+ };
+
+req_id
+ matches the req_id of the request that generated this element.
+
+completion_code
+ status of this request. 0 is success. Non-zero is an error.
+
+The DMA Bridge will generate a MSI to the host as a reaction to activity in the
+response FIFO of a DBC. The DMA Bridge hardware has an IRQ storm mitigation
+algorithm, where it will only generate a MSI when the response FIFO transitions
+from empty to non-empty (unless force MSI is enabled and triggered). In
+response to this MSI, the host is expected to drain the response FIFO, and must
+take care to handle any race conditions between draining the FIFO, and the
+device inserting elements into the FIFO.
+
+Neural Network Control (NNC) Protocol
+=====================================
+
+The NNC protocol is how the host makes requests to the QSM to manage workloads.
+It uses the QAIC_CONTROL MHI channel.
+
+Each NNC request is packaged into a message. Each message is a series of
+transactions. A passthrough type transaction can contain elements known as
+commands.
+
+QSM requires NNC messages be little endian encoded and the fields be naturally
+aligned. Since there are 64-bit elements in some NNC messages, 64-bit alignment
+must be maintained.
+
+A message contains a header and then a series of transactions. A message may be
+at most 4K in size from QSM to the host. From the host to the QSM, a message
+can be at most 64K (maximum size of a single MHI packet), but there is a
+continuation feature where message N+1 can be marked as a continuation of
+message N. This is used for exceedingly large DMA xfer transactions.
+
+Transaction descriptions
+------------------------
+
+passthrough
+ Allows userspace to send an opaque payload directly to the QSM.
+ This is used for NNC commands. Userspace is responsible for managing
+ the QSM message requirements in the payload.
+
+dma_xfer
+ DMA transfer. Describes an object that the QSM should DMA into the
+ device via address and size tuples.
+
+activate
+ Activate a workload onto NSPs. The host must provide memory to be
+ used by the DBC.
+
+deactivate
+ Deactivate an active workload and return the NSPs to idle.
+
+status
+ Query the QSM about it's NNC implementation. Returns the NNC version,
+ and if CRC is used.
+
+terminate
+ Release a user's resources.
+
+dma_xfer_cont
+ Continuation of a previous DMA transfer. If a DMA transfer
+ cannot be specified in a single message (highly fragmented), this
+ transaction can be used to specify more ranges.
+
+validate_partition
+ Query to QSM to determine if a partition identifier is valid.
+
+Each message is tagged with a user id, and a partition id. The user id allows
+QSM to track resources, and release them when the user goes away (eg the process
+crashes). A partition id identifies the resource partition that QSM manages,
+which this message applies to.
+
+Messages may have CRCs. Messages should have CRCs applied until the QSM
+reports via the status transaction that CRCs are not needed. The QSM on the
+SA9000P requires CRCs for black channel safing.
+
+Subsystem Restart (SSR)
+=======================
+
+SSR is the concept of limiting the impact of an error. An AIC100 device may
+have multiple users, each with their own workload running. If the workload of
+one user crashes, the fallout of that should be limited to that workload and not
+impact other workloads. SSR accomplishes this.
+
+If a particular workload crashes, QSM notifies the host via the QAIC_SSR MHI
+channel. This notification identifies the workload by its assigned DBC. A
+multi-stage recovery process is then used to cleanup both sides, and gets the
+DBC/NSPs into a working state.
+
+When SSR occurs, any state in the workload is lost. Any inputs that were in
+process, or queued by not yet serviced, are lost. The loaded artifacts will
+remain in on-card DDR, but the host will need to re-activate the workload if
+it desires to recover the workload.
+
+When SSR occurs for a specific NSP, the assigned DBC goes through the
+following state transactions in order:
+
+DBC_STATE_BEFORE_SHUTDOWN
+ Indicates that the affected NSP was found in an unrecoverable error
+ condition.
+DBC_STATE_AFTER_SHUTDOWN
+ Indicates that the NSP is under reset.
+DBC_STATE_BEFORE_POWER_UP
+ Indicates that the NSP's debug information has been collected, and is
+ ready to be collected by the host (if desired). At that stage the NSP
+ is restarted by QSM.
+DBC_STATE_AFTER_POWER_UP
+ Indicates that the NSP has been restarted, fully operational and is
+ in idle state.
+
+SSR also has an optional crashdump collection feature. If enabled, the host can
+collect the memory dump for the crashed NSP and dump it to the user space via
+the dev_coredump subsystem. The host can also decline the crashdump collection
+request from the device.
+
+Reliability, Accessibility, Serviceability (RAS)
+================================================
+
+AIC100 is expected to be deployed in server systems where RAS ideology is
+applied. Simply put, RAS is the concept of detecting, classifying, and
+reporting errors. While PCIe has AER (Advanced Error Reporting) which factors
+into RAS, AER does not allow for a device to report details about internal
+errors. Therefore, AIC100 implements a custom RAS mechanism. When a RAS event
+occurs, QSM will report the event with appropriate details via the QAIC_STATUS
+MHI channel. A sysadmin may determine that a particular device needs
+additional service based on RAS reports.
+
+Telemetry
+=========
+
+QSM has the ability to report various physical attributes of the device, and in
+some cases, to allow the host to control them. Examples include thermal limits,
+thermal readings, and power readings. These items are communicated via the
+QAIC_TELEMETRY MHI channel.

+ QAIC driver
+=============
+
+The QAIC driver is the Kernel Mode Driver (KMD) for the AIC100 family of AI
+accelerator products.
+
+Interrupts
+==========
+
+IRQ Storm Mitigation
+--------------------
+
+While the AIC100 DMA Bridge hardware implements an IRQ storm mitigation
+mechanism, it is still possible for an IRQ storm to occur. A storm can happen
+if the workload is particularly quick, and the host is responsive. If the host
+can drain the response FIFO as quickly as the device can insert elements into
+it, then the device will frequently transition the response FIFO from empty to
+non-empty and generate MSIs at a rate equivalent to the speed of the
+workload's ability to process inputs. The lprnet (license plate reader network)
+workload is known to trigger this condition, and can generate in excess of 100k
+MSIs per second. It has been observed that most systems cannot tolerate this
+for long, and will crash due to some form of watchdog due to the overhead of
+the interrupt controller interrupting the host CPU.
+
+To mitigate this issue, the QAIC driver implements specific IRQ handling. When
+QAIC receives an IRQ, it disables that line. This prevents the interrupt
+controller from interrupting the CPU. Then AIC drains the FIFO. Once the FIFO
+is drained, QAIC implements a "last chance" polling algorithm where QAIC will
+sleep for a time to see if the workload will generate more activity. The IRQ
+line remains disabled during this time. If no activity is detected, QAIC exits
+polling mode and reenables the IRQ line.
+
+This mitigation in QAIC is very effective. The same lprnet usecase that
+generates 100k IRQs per second (per /proc/interrupts) is reduced to roughly 64
+IRQs over 5 minutes while keeping the host system stable, and having the same
+workload throughput performance (within run-to-run noise variation).
+
+Single MSI Mode
+---------------
+
+MultiMSI is not well supported on all systems; virtualized ones even less so
+(circa 2023). Between hypervisors masking the PCIe MSI capability structure to
+large memory requirements for vIOMMUs (required for supporting MultiMSI), it is
+useful to be able to fall back to a single MSI when needed.
+
+To support this fallback, we allow the case where only one MSI is able to be
+allocated, and share that one MSI between MHI and the DBCs. The device detects
+when only one MSI has been configured and directs the interrupts for the DBCs
+to the interrupt normally used for MHI. Unfortunately, this means that the
+interrupt handlers for every DBC and MHI wake up for every interrupt that
+arrives; however, the DBC threaded irq handlers only are started when work to be
+done is detected (MHI will always start its threaded handler).
+
+If the DBC is configured to force MSI interrupts, this can circumvent the
+software IRQ storm mitigation mentioned above. Since the MSI is shared it is
+never disabled, allowing each new entry to the FIFO to trigger a new interrupt.
+
+
+Neural Network Control (NNC) Protocol
+=====================================
+
+The implementation of NNC is split between the KMD (QAIC) and UMD. In general,
+QAIC understands how to encode/decode NNC wire protocol, and elements of the
+protocol which requires kernel space knowledge to process (for example, mapping
+host memory to device IOVAs). QAIC understands the structure of a message, and
+all of the transactions. QAIC does not understand commands (the payload of a
+passthrough transaction).
+
+QAIC handles and enforces the required little endianness and 64-bit alignment,
+to the degree that it can. Since QAIC does not know the contents of a
+passthrough transaction, it relies on the UMD to satisfy the requirements.
+
+The terminate transaction is of particular use to QAIC. QAIC is not aware of
+the resources that are loaded onto a device since the majority of that activity
+occurs within NNC commands. As a result, QAIC does not have the means to
+roll back userspace activity. To ensure that a userspace client's resources
+are fully released in the case of a process crash, or a bug, QAIC uses the
+terminate command to let QSM know when a user has gone away, and the resources
+can be released.
+
+QSM can report a version number of the NNC protocol it supports. This is in the
+form of a Major number and a Minor number.
+
+Major number updates indicate changes to the NNC protocol which impact the
+message format, or transactions (impacts QAIC).
+
+Minor number updates indicate changes to the NNC protocol which impact the
+commands (does not impact QAIC).
+
+uAPI
+====
+
+QAIC creates an accel device per physical PCIe device. This accel device exists
+for as long as the PCIe device is known to Linux.
+
+The PCIe device may not be in the state to accept requests from userspace at
+all times. QAIC will trigger KOBJ_ONLINE/OFFLINE uevents to advertise when the
+device can accept requests (ONLINE) and when the device is no longer accepting
+requests (OFFLINE) because of a reset or other state transition.
+
+QAIC defines a number of driver specific IOCTLs as part of the userspace API.
+
+DRM_IOCTL_QAIC_MANAGE
+ This IOCTL allows userspace to send a NNC request to the QSM. The call will
+ block until a response is received, or the request has timed out.
+
+DRM_IOCTL_QAIC_CREATE_BO
+ This IOCTL allows userspace to allocate a buffer object (BO) which can send
+ or receive data from a workload. The call will return a GEM handle that
+ represents the allocated buffer. The BO is not usable until it has been
+ sliced (see DRM_IOCTL_QAIC_ATTACH_SLICE_BO).
+
+DRM_IOCTL_QAIC_MMAP_BO
+ This IOCTL allows userspace to prepare an allocated BO to be mmap'd into the
+ userspace process.
+
+DRM_IOCTL_QAIC_ATTACH_SLICE_BO
+ This IOCTL allows userspace to slice a BO in preparation for sending the BO
+ to the device. Slicing is the operation of describing what portions of a BO
+ get sent where to a workload. This requires a set of DMA transfers for the
+ DMA Bridge, and as such, locks the BO to a specific DBC.
+
+DRM_IOCTL_QAIC_EXECUTE_BO
+ This IOCTL allows userspace to submit a set of sliced BOs to the device. The
+ call is non-blocking. Success only indicates that the BOs have been queued
+ to the device, but does not guarantee they have been executed.
+
+DRM_IOCTL_QAIC_PARTIAL_EXECUTE_BO
+ This IOCTL operates like DRM_IOCTL_QAIC_EXECUTE_BO, but it allows userspace
+ to shrink the BOs sent to the device for this specific call. If a BO
+ typically has N inputs, but only a subset of those is available, this IOCTL
+ allows userspace to indicate that only the first M bytes of the BO should be
+ sent to the device to minimize data transfer overhead. This IOCTL dynamically
+ recomputes the slicing, and therefore has some processing overhead before the
+ BOs can be queued to the device.
+
+DRM_IOCTL_QAIC_WAIT_BO
+ This IOCTL allows userspace to determine when a particular BO has been
+ processed by the device. The call will block until either the BO has been
+ processed and can be re-queued to the device, or a timeout occurs.
+
+DRM_IOCTL_QAIC_PERF_STATS_BO
+ This IOCTL allows userspace to collect performance statistics on the most
+ recent execution of a BO. This allows userspace to construct an end to end
+ timeline of the BO processing for a performance analysis.
+
+DRM_IOCTL_QAIC_DETACH_SLICE_BO
+ This IOCTL allows userspace to remove the slicing information from a BO that
+ was originally provided by a call to DRM_IOCTL_QAIC_ATTACH_SLICE_BO. This
+ is the inverse of DRM_IOCTL_QAIC_ATTACH_SLICE_BO. The BO must be idle for
+ DRM_IOCTL_QAIC_DETACH_SLICE_BO to be called. After a successful detach slice
+ operation the BO may have new slicing information attached with a new call
+ to DRM_IOCTL_QAIC_ATTACH_SLICE_BO. After detach slice, the BO cannot be
+ executed until after a new attach slice operation. Combining attach slice
+ and detach slice calls allows userspace to use a BO with multiple workloads.
+
+Userspace Client Isolation
+==========================
+
+AIC100 supports multiple clients. Multiple DBCs can be consumed by a single
+client, and multiple clients can each consume one or more DBCs. Workloads
+may contain sensitive information therefore only the client that owns the
+workload should be allowed to interface with the DBC.
+
+Clients are identified by the instance associated with their open(). A client
+may only use memory they allocate, and DBCs that are assigned to their
+workloads. Attempts to access resources assigned to other clients will be
+rejected.
+
+Module parameters
+=================
+
+QAIC supports the following module parameters:
+
+**datapath_polling (bool)**
+
+Configures QAIC to use a polling thread for datapath events instead of relying
+on the device interrupts. Useful for platforms with broken multiMSI. Must be
+set at QAIC driver initialization. Default is 0 (off).
+
+**mhi_timeout_ms (unsigned int)**
+
+Sets the timeout value for MHI operations in milliseconds (ms). Must be set
+at the time the driver detects a device. Default is 2000 (2 seconds).
+
+**control_resp_timeout_s (unsigned int)**
+
+Sets the timeout value for QSM responses to NNC messages in seconds (s). Must
+be set at the time the driver is sending a request to QSM. Default is 60 (one
+minute).
+
+**wait_exec_default_timeout_ms (unsigned int)**
+
+Sets the default timeout for the wait_exec ioctl in milliseconds (ms). Must be
+set prior to the waic_exec ioctl call. A value specified in the ioctl call
+overrides this for that call. Default is 5000 (5 seconds).
+
+**datapath_poll_interval_us (unsigned int)**
+
+Sets the polling interval in microseconds (us) when datapath polling is active.
+Takes effect at the next polling interval. Default is 100 (100 us).
+
+**timesync_delay_ms (unsigned int)**
+
+Sets the time interval in milliseconds (ms) between two consecutive timesync
+operations. Default is 1000 (1000 ms).

+Integrity Policy Enforcement (IPE)
+==================================
+
+.. NOTE::
+
+ This is the documentation for admins, system builders, or individuals
+ attempting to use IPE. If you're looking for more developer-focused
+ documentation about IPE please see :doc:`the design docs </security/ipe>`.
+
+Overview
+--------
+
+Integrity Policy Enforcement (IPE) is a Linux Security Module that takes a
+complementary approach to access control. Unlike traditional access control
+mechanisms that rely on labels and paths for decision-making, IPE focuses
+on the immutable security properties inherent to system components. These
+properties are fundamental attributes or features of a system component
+that cannot be altered, ensuring a consistent and reliable basis for
+security decisions.
+
+To elaborate, in the context of IPE, system components primarily refer to
+files or the devices these files reside on. However, this is just a
+starting point. The concept of system components is flexible and can be
+extended to include new elements as the system evolves. The immutable
+properties include the origin of a file, which remains constant and
+unchangeable over time. For example, IPE policies can be crafted to trust
+files originating from the initramfs. Since initramfs is typically verified
+by the bootloader, its files are deemed trustworthy; "file is from
+initramfs" becomes an immutable property under IPE's consideration.
+
+The immutable property concept extends to the security features enabled on
+a file's origin, such as dm-verity or fs-verity, which provide a layer of
+integrity and trust. For example, IPE allows the definition of policies
+that trust files from a dm-verity protected device. dm-verity ensures the
+integrity of an entire device by providing a verifiable and immutable state
+of its contents. Similarly, fs-verity offers filesystem-level integrity
+checks, allowing IPE to enforce policies that trust files protected by
+fs-verity. These two features cannot be turned off once established, so
+they are considered immutable properties. These examples demonstrate how
+IPE leverages immutable properties, such as a file's origin and its
+integrity protection mechanisms, to make access control decisions.
+
+For the IPE policy, specifically, it grants the ability to enforce
+stringent access controls by assessing security properties against
+reference values defined within the policy. This assessment can be based on
+the existence of a security property (e.g., verifying if a file originates
+from initramfs) or evaluating the internal state of an immutable security
+property. The latter includes checking the roothash of a dm-verity
+protected device, determining whether dm-verity possesses a valid
+signature, assessing the digest of a fs-verity protected file, or
+determining whether fs-verity possesses a valid built-in signature. This
+nuanced approach to policy enforcement enables a highly secure and
+customizable system defense mechanism, tailored to specific security
+requirements and trust models.
+
+To enable IPE, ensure that ``CONFIG_SECURITY_IPE`` (under
+:menuselection:`Security -> Integrity Policy Enforcement (IPE)`) config
+option is enabled.
+
+Use Cases
+---------
+
+IPE works best in fixed-function devices: devices in which their purpose
+is clearly defined and not supposed to be changed (e.g. network firewall
+device in a data center, an IoT device, etcetera), where all software and
+configuration is built and provisioned by the system owner.
+
+IPE is a long-way off for use in general-purpose computing: the Linux
+community as a whole tends to follow a decentralized trust model (known as
+the web of trust), which IPE has no support for it yet. Instead, IPE
+supports PKI (public key infrastructure), which generally designates a
+set of trusted entities that provide a measure of absolute trust.
+
+Additionally, while most packages are signed today, the files inside
+the packages (for instance, the executables), tend to be unsigned. This
+makes it difficult to utilize IPE in systems where a package manager is
+expected to be functional, without major changes to the package manager
+and ecosystem behind it.
+
+The digest_cache LSM [#digest_cache_lsm]_ is a system that when combined with IPE,
+could be used to enable and support general-purpose computing use cases.
+
+Known Limitations
+-----------------
+
+IPE cannot verify the integrity of anonymous executable memory, such as
+the trampolines created by gcc closures and libffi (<3.4.2), or JIT'd code.
+Unfortunately, as this is dynamically generated code, there is no way
+for IPE to ensure the integrity of this code to form a trust basis.
+
+IPE cannot verify the integrity of programs written in interpreted
+languages when these scripts are invoked by passing these program files
+to the interpreter. This is because the way interpreters execute these
+files; the scripts themselves are not evaluated as executable code
+through one of IPE's hooks, but they are merely text files that are read
+(as opposed to compiled executables). However, with the introduction of the
+``AT_EXECVE_CHECK`` flag (:doc:`AT_EXECVE_CHECK </userspace-api/check_exec>`),
+interpreters can use it to signal the kernel that a script file will be executed,
+and request the kernel to perform LSM security checks on it.
+
+IPE's EXECUTE operation enforcement differs between compiled executables and
+interpreted scripts: For compiled executables, enforcement is triggered
+automatically by the kernel during ``execve()``, ``execveat()``, ``mmap()``
+and ``mprotect()`` syscalls when loading executable content. For interpreted
+scripts, enforcement requires explicit interpreter integration using
+``execveat()`` with ``AT_EXECVE_CHECK`` flag. Unlike exec syscalls that IPE
+intercepts during the execution process, this mechanism needs the interpreter
+to take the initiative, and existing interpreters won't be automatically
+supported unless the signal call is added.
+
+Threat Model
+------------
+
+IPE specifically targets the risk of tampering with user-space executable
+code after the kernel has initially booted, including the kernel modules
+loaded from userspace via ``modprobe`` or ``insmod``.
+
+To illustrate, consider a scenario where an untrusted binary, possibly
+malicious, is downloaded along with all necessary dependencies, including a
+loader and libc. The primary function of IPE in this context is to prevent
+the execution of such binaries and their dependencies.
+
+IPE achieves this by verifying the integrity and authenticity of all
+executable code before allowing them to run. It conducts a thorough
+check to ensure that the code's integrity is intact and that they match an
+authorized reference value (digest, signature, etc) as per the defined
+policy. If a binary does not pass this verification process, either
+because its integrity has been compromised or it does not meet the
+authorization criteria, IPE will deny its execution. Additionally, IPE
+generates audit logs which may be utilized to detect and analyze failures
+resulting from policy violation.
+
+Tampering threat scenarios include modification or replacement of
+executable code by a range of actors including:
+
+- Actors with physical access to the hardware
+- Actors with local network access to the system
+- Actors with access to the deployment system
+- Compromised internal systems under external control
+- Malicious end users of the system
+- Compromised end users of the system
+- Remote (external) compromise of the system
+
+IPE does not mitigate threats arising from malicious but authorized
+developers (with access to a signing certificate), or compromised
+developer tools used by them (i.e. return-oriented programming attacks).
+Additionally, IPE draws hard security boundary between userspace and
+kernelspace. As a result, kernel-level exploits are considered outside
+the scope of IPE and mitigation is left to other mechanisms.
+
+Policy
+------
+
+IPE policy is a plain-text [#devdoc]_ policy composed of multiple statements
+over several lines. There is one required line, at the top of the
+policy, indicating the policy name, and the policy version, for
+instance::
+
+ policy_name=Ex_Policy policy_version=0.0.0
+
+The policy name is a unique key identifying this policy in a human
+readable name. This is used to create nodes under securityfs as well as
+uniquely identify policies to deploy new policies vs update existing
+policies.
+
+The policy version indicates the current version of the policy (NOT the
+policy syntax version). This is used to prevent rollback of policy to
+potentially insecure previous versions of the policy.
+
+The next portion of IPE policy are rules. Rules are formed by key=value
+pairs, known as properties. IPE rules require two properties: ``action``,
+which determines what IPE does when it encounters a match against the
+rule, and ``op``, which determines when the rule should be evaluated.
+The ordering is significant, a rule must start with ``op``, and end with
+``action``. Thus, a minimal rule is::
+
+ op=EXECUTE action=ALLOW
+
+This example will allow any execution. Additional properties are used to
+assess immutable security properties about the files being evaluated.
+These properties are intended to be descriptions of systems within the
+kernel that can provide a measure of integrity verification, such that IPE
+can determine the trust of the resource based on the value of the property.
+
+Rules are evaluated top-to-bottom. As a result, any revocation rules,
+or denies should be placed early in the file to ensure that these rules
+are evaluated before a rule with ``action=ALLOW``.
+
+IPE policy supports comments. The character '#' will function as a
+comment, ignoring all characters to the right of '#' until the newline.
+
+The default behavior of IPE evaluations can also be expressed in policy,
+through the ``DEFAULT`` statement. This can be done at a global level,
+or a per-operation level::
+
+ # Global
+ DEFAULT action=ALLOW
+
+ # Operation Specific
+ DEFAULT op=EXECUTE action=ALLOW
+
+A default must be set for all known operations in IPE. If you want to
+preserve older policies being compatible with newer kernels that can introduce
+new operations, set a global default of ``ALLOW``, then override the
+defaults on a per-operation basis (as above).
+
+With configurable policy-based LSMs, there's several issues with
+enforcing the configurable policies at startup, around reading and
+parsing the policy:
+
+1. The kernel *should* not read files from userspace, so directly reading
+ the policy file is prohibited.
+2. The kernel command line has a character limit, and one kernel module
+ should not reserve the entire character limit for its own
+ configuration.
+3. There are various boot loaders in the kernel ecosystem, so handing
+ off a memory block would be costly to maintain.
+
+As a result, IPE has addressed this problem through a concept of a "boot
+policy". A boot policy is a minimal policy which is compiled into the
+kernel. This policy is intended to get the system to a state where
+userspace is set up and ready to receive commands, at which point a more
+complex policy can be deployed via securityfs. The boot policy can be
+specified via ``SECURITY_IPE_BOOT_POLICY`` config option, which accepts
+a path to a plain-text version of the IPE policy to apply. This policy
+will be compiled into the kernel. If not specified, IPE will be disabled
+until a policy is deployed and activated through securityfs.
+
+Deploying Policies
+~~~~~~~~~~~~~~~~~~
+
+Policies can be deployed from userspace through securityfs. These policies
+are signed through the PKCS#7 message format to enforce some level of
+authorization of the policies (prohibiting an attacker from gaining
+unconstrained root, and deploying an "allow all" policy). These
+policies must be signed by a certificate that chains to the
+``SYSTEM_TRUSTED_KEYRING``, or to the secondary and/or platform keyrings if
+``CONFIG_IPE_POLICY_SIG_SECONDARY_KEYRING`` and/or
+``CONFIG_IPE_POLICY_SIG_PLATFORM_KEYRING`` are enabled, respectively.
+With openssl, the policy can be signed by::

+
+Deploying the policies is done through securityfs, through the
+``new_policy`` node. To deploy a policy, simply cat the file into the
+securityfs node::
+
+ cat "$MY_POLICY.p7b" > /sys/kernel/security/ipe/new_policy
+
+Upon success, this will create one subdirectory under
+``/sys/kernel/security/ipe/policies/``. The subdirectory will be the
+``policy_name`` field of the policy deployed, so for the example above,
+the directory will be ``/sys/kernel/security/ipe/policies/Ex_Policy``.
+Within this directory, there will be seven files: ``pkcs7``, ``policy``,
+``name``, ``version``, ``active``, ``update``, and ``delete``.
+
+The ``pkcs7`` file is read-only. Reading it returns the raw PKCS#7 data
+that was provided to the kernel, representing the policy. If the policy being
+read is the boot policy, this will return ``ENOENT``, as it is not signed.
+
+The ``policy`` file is read only. Reading it returns the PKCS#7 inner
+content of the policy, which will be the plain text policy.
+
+The ``active`` file is used to set a policy as the currently active policy.
+This file is rw, and accepts a value of ``"1"`` to set the policy as active.
+Since only a single policy can be active at one time, all other policies
+will be marked inactive. The policy being marked active must have a policy
+version greater or equal to the currently-running version.
+
+The ``update`` file is used to update a policy that is already present
+in the kernel. This file is write-only and accepts a PKCS#7 signed
+policy. Two checks will always be performed on this policy: First, the
+``policy_names`` must match with the updated version and the existing
+version. Second the updated policy must have a policy version greater than
+the currently-running version. This is to prevent rollback attacks.
+
+The ``delete`` file is used to remove a policy that is no longer needed.
+This file is write-only and accepts a value of ``1`` to delete the policy.
+On deletion, the securityfs node representing the policy will be removed.
+However, delete the current active policy is not allowed and will return
+an operation not permitted error.
+
+Similarly, writing to both ``update`` and ``new_policy`` could result in
+bad message(policy syntax error) or file exists error. The latter error happens
+when trying to deploy a policy with a ``policy_name`` while the kernel already
+has a deployed policy with the same ``policy_name``.
+
+Deploying a policy will *not* cause IPE to start enforcing the policy. IPE will
+only enforce the policy marked active. Note that only one policy can be active
+at a time.
+
+Once deployment is successful, the policy can be activated, by writing file
+``/sys/kernel/security/ipe/policies/$policy_name/active``.
+For example, the ``Ex_Policy`` can be activated by::
+
+ echo 1 > "/sys/kernel/security/ipe/policies/Ex_Policy/active"
+
+From above point on, ``Ex_Policy`` is now the enforced policy on the
+system.
+
+IPE also provides a way to delete policies. This can be done via the
+``delete`` securityfs node,
+``/sys/kernel/security/ipe/policies/$policy_name/delete``.
+Writing ``1`` to that file deletes the policy::
+
+ echo 1 > "/sys/kernel/security/ipe/policies/$policy_name/delete"
+
+There is only one requirement to delete a policy: the policy being deleted
+must be inactive.
+
+.. NOTE::
+
+ If a traditional MAC system is enabled (SELinux, apparmor, smack), all
+ writes to ipe's securityfs nodes require ``CAP_MAC_ADMIN``.
+
+Modes
+~~~~~
+
+IPE supports two modes of operation: permissive (similar to SELinux's
+permissive mode) and enforced. In permissive mode, all events are
+checked and policy violations are logged, but the policy is not really
+enforced. This allows users to test policies before enforcing them.
+
+The default mode is enforce, and can be changed via the kernel command
+line parameter ``ipe.enforce=(0|1)``, or the securityfs node
+``/sys/kernel/security/ipe/enforce``.
+
+.. NOTE::
+
+ If a traditional MAC system is enabled (SELinux, apparmor, smack, etcetera),
+ all writes to ipe's securityfs nodes require ``CAP_MAC_ADMIN``.

+Success Auditing
+^^^^^^^^^^^^^^^^
+
+IPE supports success auditing. When enabled, all events that pass IPE
+policy and are not blocked will emit an audit event. This is disabled by
+default, and can be enabled via the kernel command line
+``ipe.success_audit=(0|1)`` or
+``/sys/kernel/security/ipe/success_audit`` securityfs file.
+
+This is *very* noisy, as IPE will check every userspace binary on the
+system, but is useful for debugging policies.
+
+.. NOTE::
+
+ If a traditional MAC system is enabled (SELinux, apparmor, smack, etcetera),
+ all writes to ipe's securityfs nodes require ``CAP_MAC_ADMIN``.
+
+Properties
+----------
+
+As explained above, IPE properties are ``key=value`` pairs expressed in IPE
+policy. Two properties are built-into the policy parser: 'op' and 'action'.
+The other properties are used to restrict immutable security properties
+about the files being evaluated. Currently those properties are:
+'``boot_verified``', '``dmverity_signature``', '``dmverity_roothash``',
+'``fsverity_signature``', '``fsverity_digest``'. A description of all
+properties supported by IPE are listed below:
+
+op
+~~
+
+Indicates the operation for a rule to apply to. Must be in every rule,
+as the first token. IPE supports the following operations:
+
+ ``EXECUTE``
+
+ Pertains to any file attempting to be executed, or loaded as an
+ executable.
+
+ ``FIRMWARE``:
+
+ Pertains to firmware being loaded via the firmware_class interface.
+ This covers both the preallocated buffer and the firmware file
+ itself.
+
+ ``KMODULE``:
+
+ Pertains to loading kernel modules via ``modprobe`` or ``insmod``.
+
+ ``KEXEC_IMAGE``:
+
+ Pertains to kernel images loading via ``kexec``.
+
+ ``KEXEC_INITRAMFS``
+
+ Pertains to initrd images loading via ``kexec --initrd``.
+
+ ``POLICY``:
+
+ Controls loading policies via reading a kernel-space initiated read.
+
+ An example of such is loading IMA policies by writing the path
+ to the policy file to ``$securityfs/ima/policy``
+
+ ``X509_CERT``:
+
+ Controls loading IMA certificates through the Kconfigs,
+ ``CONFIG_IMA_X509_PATH`` and ``CONFIG_EVM_X509_PATH``.
+
+action
+~~~~~~
+
+ Determines what IPE should do when a rule matches. Must be in every
+ rule, as the final clause. Can be one of:
+
+ ``ALLOW``:
+
+ If the rule matches, explicitly allow access to the resource to proceed
+ without executing any more rules.
+
+ ``DENY``:
+
+ If the rule matches, explicitly prohibit access to the resource to
+ proceed without executing any more rules.
+
+boot_verified
+~~~~~~~~~~~~~
+
+ This property can be utilized for authorization of files from initramfs.
+ The format of this property is::
+
+ boot_verified=(TRUE|FALSE)
+
+
+ .. WARNING::
+
+ This property will trust files from initramfs(rootfs). It should
+ only be used during early booting stage. Before mounting the real
+ rootfs on top of the initramfs, initramfs script will recursively
+ remove all files and directories on the initramfs. This is typically
+ implemented by using switch_root(8) [#switch_root]_. Therefore the
+ initramfs will be empty and not accessible after the real
+ rootfs takes over. It is advised to switch to a different policy
+ that doesn't rely on the property after this point.
+ This ensures that the trust policies remain relevant and effective
+ throughout the system's operation.
+
+dmverity_roothash
+~~~~~~~~~~~~~~~~~
+
+ This property can be utilized for authorization or revocation of
+ specific dm-verity volumes, identified via their root hashes. It has a
+ dependency on the DM_VERITY module. This property is controlled by
+ the ``IPE_PROP_DM_VERITY`` config option, it will be automatically
+ selected when ``SECURITY_IPE`` and ``DM_VERITY`` are all enabled.
+ The format of this property is::
+
+ dmverity_roothash=DigestName:HexadecimalString
+
+ The supported DigestNames for dmverity_roothash are [#dmveritydigests]_
+
+ + blake2b-512
+ + blake2s-256
+ + sha256
+ + sha384
+ + sha512
+ + sha3-224
+ + sha3-256
+ + sha3-384
+ + sha3-512
+ + sm3
+ + rmd160
+
+dmverity_signature
+~~~~~~~~~~~~~~~~~~
+
+ This property can be utilized for authorization of all dm-verity
+ volumes that have a signed roothash that validated by a keyring
+ specified by dm-verity's configuration, either the system trusted
+ keyring, or the secondary keyring. It depends on
+ ``DM_VERITY_VERIFY_ROOTHASH_SIG`` config option and is controlled by
+ the ``IPE_PROP_DM_VERITY_SIGNATURE`` config option, it will be automatically
+ selected when ``SECURITY_IPE``, ``DM_VERITY`` and
+ ``DM_VERITY_VERIFY_ROOTHASH_SIG`` are all enabled.
+ The format of this property is::
+
+ dmverity_signature=(TRUE|FALSE)
+
+fsverity_digest
+~~~~~~~~~~~~~~~
+
+ This property can be utilized for authorization of specific fsverity
+ enabled files, identified via their fsverity digests.
+ It depends on ``FS_VERITY`` config option and is controlled by
+ the ``IPE_PROP_FS_VERITY`` config option, it will be automatically
+ selected when ``SECURITY_IPE`` and ``FS_VERITY`` are all enabled.
+ The format of this property is::
+
+ fsverity_digest=DigestName:HexadecimalString
+
+ The supported DigestNames for fsverity_digest are [#fsveritydigest]_
+
+ + sha256
+ + sha512
+
+fsverity_signature
+~~~~~~~~~~~~~~~~~~
+
+ This property is used to authorize all fs-verity enabled files that have
+ been verified by fs-verity's built-in signature mechanism. The signature
+ verification relies on a key stored within the ".fs-verity" keyring. It
+ depends on ``FS_VERITY_BUILTIN_SIGNATURES`` config option and
+ it is controlled by the ``IPE_PROP_FS_VERITY`` config option,
+ it will be automatically selected when ``SECURITY_IPE``, ``FS_VERITY``
+ and ``FS_VERITY_BUILTIN_SIGNATURES`` are all enabled.
+ The format of this property is::
+
+ fsverity_signature=(TRUE|FALSE)

+FAQ
+---
+
+Q:
+ What's the difference between other LSMs which provide a measure of
+ trust-based access control?
+
+A:
+
+ In general, there's two other LSMs that can provide similar functionality:
+ IMA, and Loadpin.
+
+ IMA and IPE are functionally very similar. The significant difference between
+ the two is the policy. [#devdoc]_
+
+ Loadpin and IPE differ fairly dramatically, as Loadpin only covers the IPE's
+ kernel read operations, whereas IPE is capable of controlling execution
+ on top of kernel read. The trust model is also different; Loadpin roots its
+ trust in the initial super-block, whereas trust in IPE is stemmed from kernel
+ itself (via ``SYSTEM_TRUSTED_KEYS``).

+Landlock: system-wide management
+================================
+
+:Author: Mickaël Salaün
+:Date: March 2025
+
+Landlock can leverage the audit framework to log events.
+
+User space documentation can be found here:
+Documentation/userspace-api/landlock.rst.
+
+Audit
+=====
+
+Denied access requests are logged by default for a sandboxed program if `audit`
+is enabled. This default behavior can be changed with the
+sys_landlock_restrict_self() flags (cf.
+Documentation/userspace-api/landlock.rst). Landlock logs can also be masked
+thanks to audit rules. Landlock can generate 2 audit record types.
+
+Record types
+------------
+
+AUDIT_LANDLOCK_ACCESS
+ This record type identifies a denied access request to a kernel resource.
+ The ``domain`` field indicates the ID of the domain that blocked the
+ request. The ``blockers`` field indicates the cause(s) of this denial
+ (separated by a comma), and the following fields identify the kernel object
+ (similar to SELinux). There may be more than one of this record type per
+ audit event.
+
+ Example with a file link request generating two records in the same event::
+
+ domain=195ba459b blockers=fs.refer path="/usr/bin" dev="vda2" ino=351
+ domain=195ba459b blockers=fs.make_reg,fs.refer path="/usr/local" dev="vda2" ino=365
+
+AUDIT_LANDLOCK_DOMAIN
+ This record type describes the status of a Landlock domain. The ``status``
+ field can be either ``allocated`` or ``deallocated``.
+
+ The ``allocated`` status is part of the same audit event and follows
+ the first logged ``AUDIT_LANDLOCK_ACCESS`` record of a domain. It identifies
+ Landlock domain information at the time of the sys_landlock_restrict_self()
+ call with the following fields:
+
+ - the ``domain`` ID
+ - the enforcement ``mode``
+ - the domain creator's ``pid``
+ - the domain creator's ``uid``
+ - the domain creator's executable path (``exe``)
+ - the domain creator's command line (``comm``)
+
+ Example::
+
+ domain=195ba459b status=allocated mode=enforcing pid=300 uid=0 exe="/root/sandboxer" comm="sandboxer"
+
+ The ``deallocated`` status is an event on its own and it identifies a
+ Landlock domain release. After such event, it is guarantee that the
+ related domain ID will never be reused during the lifetime of the system.
+ The ``domain`` field indicates the ID of the domain which is released, and
+ the ``denials`` field indicates the total number of denied access request,
+ which might not have been logged according to the audit rules and
+ sys_landlock_restrict_self()'s flags.
+
+ Example::
+
+ domain=195ba459b status=deallocated denials=3
+
+
+Event samples
+--------------
+
+Here are two examples of log events (see serial numbers).
+
+In this example a sandboxed program (``kill``) tries to send a signal to the
+init process, which is denied because of the signal scoping restriction
+(``LL_SCOPED=s``)::
+
+ $ LL_FS_RO=/ LL_FS_RW=/ LL_SCOPED=s LL_FORCE_LOG=1 ./sandboxer kill 1
+
+This command generates two events, each identified with a unique serial
+number following a timestamp (``msg=audit(1729738800.268:30)``). The first
+event (serial ``30``) contains 4 records. The first record
+(``type=LANDLOCK_ACCESS``) shows an access denied by the domain `1a6fdc66f`.
+The cause of this denial is signal scopping restriction
+(``blockers=scope.signal``). The process that would have receive this signal
+is the init process (``opid=1 ocomm="systemd"``).
+
+The second record (``type=LANDLOCK_DOMAIN``) describes (``status=allocated``)
+domain `1a6fdc66f`. This domain was created by process ``286`` executing the
+``/root/sandboxer`` program launched by the root user.
+
+The third record (``type=SYSCALL``) describes the syscall, its provided
+arguments, its result (``success=no exit=-1``), and the process that called it.
+
+The fourth record (``type=PROCTITLE``) shows the command's name as an
+hexadecimal value. This can be translated with ``python -c
+'print(bytes.fromhex("6B696C6C0031"))'``.
+
+Finally, the last record (``type=LANDLOCK_DOMAIN``) is also the only one from
+the second event (serial ``31``). It is not tied to a direct user space action
+but an asynchronous one to free resources tied to a Landlock domain
+(``status=deallocated``). This can be useful to know that the following logs
+will not concern the domain ``1a6fdc66f`` anymore. This record also summarize
+the number of requests this domain denied (``denials=1``), whether they were
+logged or not.
+
+.. code-block::
+
+ type=LANDLOCK_ACCESS msg=audit(1729738800.268:30): domain=1a6fdc66f blockers=scope.signal opid=1 ocomm="systemd"

+
+Event filtering
+---------------
+
+If you get spammed with audit logs related to Landlock, this is either an
+attack attempt or a bug in the security policy. We can put in place some
+filters to limit noise with two complementary ways:
+
+- with sys_landlock_restrict_self()'s flags if we can fix the sandboxed
+ programs,
+- or with audit rules (see :manpage:`auditctl(8)`).

+==================================================
+Reliability, Availability and Serviceability (RAS)
+==================================================
+
+This documents different aspects of the RAS functionality present in the
+kernel.
+
+RAS concepts
+************
+
+Reliability, Availability and Serviceability (RAS) is a concept used on
+servers meant to measure their robustness.
+
+Reliability
+ is the probability that a system will produce correct outputs.
+
+ * Generally measured as Mean Time Between Failures (MTBF)
+ * Enhanced by features that help to avoid, detect and repair hardware faults
+
+Availability
+ is the probability that a system is operational at a given time
+
+ * Generally measured as a percentage of downtime per a period of time
+ * Often uses mechanisms to detect and correct hardware faults in
+ runtime;
+
+Serviceability (or maintainability)
+ is the simplicity and speed with which a system can be repaired or
+ maintained
+
+ * Generally measured on Mean Time Between Repair (MTBR)
+
+Improving RAS
+-------------
+
+In order to reduce systems downtime, a system should be capable of detecting
+hardware errors, and, when possible correcting them in runtime. It should
+also provide mechanisms to detect hardware degradation, in order to warn
+the system administrator to take the action of replacing a component before
+it causes data loss or system downtime.
+
+Among the monitoring measures, the most usual ones include:
+
+* CPU – detect errors at instruction execution and at L1/L2/L3 caches;
+* Memory – add error correction logic (ECC) to detect and correct errors;
+* I/O – add CRC checksums for transferred data;
+* Storage – RAID, journal file systems, checksums,
+ Self-Monitoring, Analysis and Reporting Technology (SMART).
+
+By monitoring the number of occurrences of error detections, it is possible
+to identify if the probability of hardware errors is increasing, and, on such
+case, do a preventive maintenance to replace a degraded component while
+those errors are correctable.
+
+Types of errors
+---------------
+
+Most mechanisms used on modern systems use technologies like Hamming
+Codes that allow error correction when the number of errors on a bit packet
+is below a threshold. If the number of errors is above, those mechanisms
+can indicate with a high degree of confidence that an error happened, but
+they can't correct.
+
+Also, sometimes an error occur on a component that it is not used. For
+example, a part of the memory that it is not currently allocated.
+
+That defines some categories of errors:
+
+* **Correctable Error (CE)** - the error detection mechanism detected and
+ corrected the error. Such errors are usually not fatal, although some
+ Kernel mechanisms allow the system administrator to consider them as fatal.
+
+* **Uncorrected Error (UE)** - the amount of errors happened above the error
+ correction threshold, and the system was unable to auto-correct.
+
+* **Fatal Error** - when an UE error happens on a critical component of the
+ system (for example, a piece of the Kernel got corrupted by an UE), the
+ only reliable way to avoid data corruption is to hang or reboot the machine.
+
+* **Non-fatal Error** - when an UE error happens on an unused component,
+ like a CPU in power down state or an unused memory bank, the system may
+ still run, eventually replacing the affected hardware by a hot spare,
+ if available.
+
+ Also, when an error happens on a userspace process, it is also possible to
+ kill such process and let userspace restart it.
+
+The mechanism for handling non-fatal errors is usually complex and may
+require the help of some userspace application, in order to apply the
+policy desired by the system administrator.
+
+Identifying a bad hardware component
+------------------------------------
+
+Just detecting a hardware flaw is usually not enough, as the system needs
+to pinpoint to the minimal replaceable unit (MRU) that should be exchanged
+to make the hardware reliable again.
+
+So, it requires not only error logging facilities, but also mechanisms that
+will translate the error message to the silkscreen or component label for
+the MRU.
+
+Typically, it is very complex for memory, as modern CPUs interlace memory
+from different memory modules, in order to provide a better performance. The
+DMI BIOS usually have a list of memory module labels, with can be obtained
+using the ``dmidecode`` tool. For example, on a desktop machine, it shows::
+
+ Memory Device
+ Total Width: 64 bits
+ Data Width: 64 bits
+ Size: 16384 MB
+ Form Factor: SODIMM
+ Set: None
+ Locator: ChannelA-DIMM0
+ Bank Locator: BANK 0
+ Type: DDR4
+ Type Detail: Synchronous
+ Speed: 2133 MHz
+ Rank: 2
+ Configured Clock Speed: 2133 MHz
+
+On the above example, a DDR4 SO-DIMM memory module is located at the
+system's memory labeled as "BANK 0", as given by the *bank locator* field.
+Please notice that, on such system, the *total width* is equal to the
+*data width*. It means that such memory module doesn't have error
+detection/correction mechanisms.
+
+Unfortunately, not all systems use the same field to specify the memory
+bank. On this example, from an older server, ``dmidecode`` shows::
+
+ Memory Device
+ Array Handle: 0x1000
+ Error Information Handle: Not Provided
+ Total Width: 72 bits
+ Data Width: 64 bits
+ Size: 8192 MB
+ Form Factor: DIMM
+ Set: 1
+ Locator: DIMM_A1
+ Bank Locator: Not Specified
+ Type: DDR3
+ Type Detail: Synchronous Registered (Buffered)
+ Speed: 1600 MHz
+ Rank: 2
+ Configured Clock Speed: 1600 MHz
+
+There, the DDR3 RDIMM memory module is located at the system's memory labeled
+as "DIMM_A1", as given by the *locator* field. Please notice that this
+memory module has 64 bits of *data width* and 72 bits of *total width*. So,
+it has 8 extra bits to be used by error detection and correction mechanisms.
+Such kind of memory is called Error-correcting code memory (ECC memory).
+
+To make things even worse, it is not uncommon that systems with different
+labels on their system's board to use exactly the same BIOS, meaning that
+the labels provided by the BIOS won't match the real ones.
+
+ECC memory
+----------
+
+As mentioned in the previous section, ECC memory has extra bits to be
+used for error correction. In the above example, a memory module has
+64 bits of *data width*, and 72 bits of *total width*. The extra 8
+bits which are used for the error detection and correction mechanisms
+are referred to as the *syndrome*\ [#f1]_\ [#f2]_.
+
+So, when the cpu requests the memory controller to write a word with
+*data width*, the memory controller calculates the *syndrome* in real time,
+using Hamming code, or some other error correction code, like SECDED+,
+producing a code with *total width* size. Such code is then written
+on the memory modules.
+
+At read, the *total width* bits code is converted back, using the same
+ECC code used on write, producing a word with *data width* and a *syndrome*.
+The word with *data width* is sent to the CPU, even when errors happen.
+
+The memory controller also looks at the *syndrome* in order to check if
+there was an error, and if the ECC code was able to fix such error.
+If the error was corrected, a Corrected Error (CE) happened. If not, an
+Uncorrected Error (UE) happened.
+
+The information about the CE/UE errors is stored on some special registers
+at the memory controller and can be accessed by reading such registers,
+either by BIOS, by some special CPUs or by Linux EDAC driver. On x86 64
+bit CPUs, such errors can also be retrieved via the Machine Check
+Architecture (MCA)\ [#f3]_.
+
+.. [#f1] Please notice that several memory controllers allow operation on a
+ mode called "Lock-Step", where it groups two memory modules together,
+ doing 128-bit reads/writes. That gives 16 bits for error correction, with
+ significantly improves the error correction mechanism, at the expense
+ that, when an error happens, there's no way to know what memory module is
+ to blame. So, it has to blame both memory modules.
+
+.. [#f2] Some memory controllers also allow using memory in mirror mode.
+ On such mode, the same data is written to two memory modules. At read,
+ the system checks both memory modules, in order to check if both provide
+ identical data. On such configuration, when an error happens, there's no
+ way to know what memory module is to blame. So, it has to blame both
+ memory modules (or 4 memory modules, if the system is also on Lock-step
+ mode).
+
+.. [#f3] For more details about the Machine Check Architecture (MCA),
+ please read Documentation/arch/x86/x86_64/machinecheck.rst at the Kernel tree.
+
+EDAC - Error Detection And Correction
+*************************************
+
+.. note::
+
+ "bluesmoke" was the name for this device driver subsystem when it
+ was "out-of-tree" and maintained at http://bluesmoke.sourceforge.net.
+ That site is mostly archaic now and can be used only for historical
+ purposes.
+
+ When the subsystem was pushed upstream for the first time, on
+ Kernel 2.6.16, it was renamed to ``EDAC``.
+
+Purpose
+-------
+
+The ``edac`` kernel module's goal is to detect and report hardware errors
+that occur within the computer system running under linux.
+
+Memory
+------
+
+Memory Correctable Errors (CE) and Uncorrectable Errors (UE) are the
+primary errors being harvested. These types of errors are harvested by
+the ``edac_mc`` device.
+
+Detecting CE events, then harvesting those events and reporting them,
+**can** but must not necessarily be a predictor of future UE events. With
+CE events only, the system can and will continue to operate as no data
+has been damaged yet.
+
+However, preventive maintenance and proactive part replacement of memory
+modules exhibiting CEs can reduce the likelihood of the dreaded UE events
+and system panics.
+
+Other hardware elements
+-----------------------
+
+A new feature for EDAC, the ``edac_device`` class of device, was added in
+the 2.6.23 version of the kernel.
+
+This new device type allows for non-memory type of ECC hardware detectors
+to have their states harvested and presented to userspace via the sysfs
+interface.
+
+Some architectures have ECC detectors for L1, L2 and L3 caches,
+along with DMA engines, fabric switches, main data path switches,
+interconnections, and various other hardware data paths. If the hardware
+reports it, then an edac_device device probably can be constructed to
+harvest and present that to userspace.
+
+
+PCI bus scanning
+----------------
+
+In addition, PCI devices are scanned for PCI Bus Parity and SERR Errors
+in order to determine if errors are occurring during data transfers.
+
+The presence of PCI Parity errors must be examined with a grain of salt.
+There are several add-in adapters that do **not** follow the PCI specification
+with regards to Parity generation and reporting. The specification says
+the vendor should tie the parity status bits to 0 if they do not intend
+to generate parity. Some vendors do not do this, and thus the parity bit
+can "float" giving false positives.
+
+There is a PCI device attribute located in sysfs that is checked by
+the EDAC PCI scanning code. If that attribute is set, PCI parity/error
+scanning is skipped for that device. The attribute is::
+
+ broken_parity_status
+
+and is located in ``/sys/devices/pci<XXX>/0000:XX:YY.Z`` directories for
+PCI devices.
+
+
+Versioning
+----------
+
+EDAC is composed of a "core" module (``edac_core.ko``) and several Memory
+Controller (MC) driver modules. On a given system, the CORE is loaded
+and one MC driver will be loaded. Both the CORE and the MC driver (or
+``edac_device`` driver) have individual versions that reflect current
+release level of their respective modules.
+
+Thus, to "report" on what version a system is running, one must report
+both the CORE's and the MC driver's versions.
+
+
+Loading
+-------
+
+If ``edac`` was statically linked with the kernel then no loading
+is necessary. If ``edac`` was built as modules then simply modprobe
+the ``edac`` pieces that you need. You should be able to modprobe
+hardware-specific modules and have the dependencies load the necessary
+core modules.
+
+Example::
+
+ $ modprobe amd76x_edac
+
+loads both the ``amd76x_edac.ko`` memory controller module and the
+``edac_mc.ko`` core module.
+
+
+Sysfs interface
+---------------
+
+EDAC presents a ``sysfs`` interface for control and reporting purposes. It
+lives in the /sys/devices/system/edac directory.
+
+Within this directory there currently reside 2 components:
+
+ ======= ==============================
+ mc memory controller(s) system
+ pci PCI control and status system
+ ======= ==============================
+
+
+
+Memory Controller (mc) Model
+----------------------------
+
+Each ``mc`` device controls a set of memory modules [#f4]_. These modules
+are laid out in a Chip-Select Row (``csrowX``) and Channel table (``chX``).
+There can be multiple csrows and multiple channels.
+
+.. [#f4] Nowadays, the term DIMM (Dual In-line Memory Module) is widely
+ used to refer to a memory module, although there are other memory
+ packaging alternatives, like SO-DIMM, SIMM, etc. The UEFI
+ specification (Version 2.7) defines a memory module in the Common
+ Platform Error Record (CPER) section to be an SMBIOS Memory Device
+ (Type 17). Along this document, and inside the EDAC subsystem, the term
+ "dimm" is used for all memory modules, even when they use a
+ different kind of packaging.
+
+Memory controllers allow for several csrows, with 8 csrows being a
+typical value. Yet, the actual number of csrows depends on the layout of
+a given motherboard, memory controller and memory module characteristics.
+
+Dual channels allow for dual data length (e. g. 128 bits, on 64 bit systems)
+data transfers to/from the CPU from/to memory. Some newer chipsets allow
+for more than 2 channels, like Fully Buffered DIMMs (FB-DIMMs) memory
+controllers. The following example will assume 2 channels:
+
+ +------------+-----------------------+
+ | CS Rows | Channels |
+ +------------+-----------+-----------+
+ | | ``ch0`` | ``ch1`` |
+ +============+===========+===========+
+ | |**DIMM_A0**|**DIMM_B0**|
+ +------------+-----------+-----------+
+ | ``csrow0`` | rank0 | rank0 |
+ +------------+-----------+-----------+
+ | ``csrow1`` | rank1 | rank1 |
+ +------------+-----------+-----------+
+ | |**DIMM_A1**|**DIMM_B1**|
+ +------------+-----------+-----------+
+ | ``csrow2`` | rank0 | rank0 |
+ +------------+-----------+-----------+
+ | ``csrow3`` | rank1 | rank1 |
+ +------------+-----------+-----------+
+
+In the above example, there are 4 physical slots on the motherboard
+for memory DIMMs:
+
+ +---------+---------+
+ | DIMM_A0 | DIMM_B0 |
+ +---------+---------+
+ | DIMM_A1 | DIMM_B1 |
+ +---------+---------+
+
+Labels for these slots are usually silk-screened on the motherboard.
+Slots labeled ``A`` are channel 0 in this example. Slots labeled ``B`` are
+channel 1. Notice that there are two csrows possible on a physical DIMM.
+These csrows are allocated their csrow assignment based on the slot into
+which the memory DIMM is placed. Thus, when 1 DIMM is placed in each
+Channel, the csrows cross both DIMMs.
+
+Memory DIMMs come single or dual "ranked". A rank is a populated csrow.
+In the example above 2 dual ranked DIMMs are similarly placed. Thus,
+both csrow0 and csrow1 are populated. On the other hand, when 2 single
+ranked DIMMs are placed in slots DIMM_A0 and DIMM_B0, then they will
+have just one csrow (csrow0) and csrow1 will be empty. The pattern
+repeats itself for csrow2 and csrow3. Also note that some memory
+controllers don't have any logic to identify the memory module, see
+``rankX`` directories below.
+
+The representation of the above is reflected in the directory
+tree in EDAC's sysfs interface. Starting in directory
+``/sys/devices/system/edac/mc``, each memory controller will be
+represented by its own ``mcX`` directory, where ``X`` is the
+index of the MC::
+
+ ..../edac/mc/
+ |
+ |->mc0
+ |->mc1
+ |->mc2
+ ....
+
+Within each of the ``mcX`` directory are several EDAC control and
+attribute files.
+
+``mcX`` directories
+-------------------
+
+In ``mcX`` directories are EDAC control and attribute files for
+this ``X`` instance of the memory controllers.
+
+For a description of the sysfs API, please see:
+
+ Documentation/ABI/testing/sysfs-devices-edac
+
+
+``dimmX`` or ``rankX`` directories
+----------------------------------
+
+The recommended way to use the EDAC subsystem is to look at the information
+provided by the ``dimmX`` or ``rankX`` directories [#f5]_.
+
+A typical EDAC system has the following structure under
+``/sys/devices/system/edac/``\ [#f6]_::
+
+ /sys/devices/system/edac/
+ ├── mc
+ │   ├── mc0
+ │   │   ├── ce_count

+
+In the ``dimmX`` directories are EDAC control and attribute files for
+this ``X`` memory module:
+
+- ``size`` - Total memory managed by this csrow attribute file
+
+ This attribute file displays, in count of megabytes, the memory
+ that this csrow contains.
+
+- ``dimm_ue_count`` - Uncorrectable Errors count attribute file
+
+ This attribute file displays the total count of uncorrectable
+ errors that have occurred on this DIMM. If panic_on_ue is set
+ this counter will not have a chance to increment, since EDAC
+ will panic the system.
+
+- ``dimm_ce_count`` - Correctable Errors count attribute file
+
+ This attribute file displays the total count of correctable
+ errors that have occurred on this DIMM. This count is very
+ important to examine. CEs provide early indications that a
+ DIMM is beginning to fail. This count field should be
+ monitored for non-zero values and report such information
+ to the system administrator.
+
+- ``dimm_dev_type`` - Device type attribute file
+
+ This attribute file will display what type of DRAM device is
+ being utilized on this DIMM.
+ Examples:
+
+ - x1
+ - x2
+ - x4
+ - x8
+
+- ``dimm_edac_mode`` - EDAC Mode of operation attribute file
+
+ This attribute file will display what type of Error detection
+ and correction is being utilized.
+
+- ``dimm_label`` - memory module label control file
+
+ This control file allows this DIMM to have a label assigned
+ to it. With this label in the module, when errors occur
+ the output can provide the DIMM label in the system log.
+ This becomes vital for panic events to isolate the
+ cause of the UE event.
+
+ DIMM Labels must be assigned after booting, with information
+ that correctly identifies the physical slot with its
+ silk screen label. This information is currently very
+ motherboard specific and determination of this information
+ must occur in userland at this time.
+
+- ``dimm_location`` - location of the memory module
+
+ The location can have up to 3 levels, and describe how the
+ memory controller identifies the location of a memory module.
+ Depending on the type of memory and memory controller, it
+ can be:
+
+ - *csrow* and *channel* - used when the memory controller
+ doesn't identify a single DIMM - e. g. in ``rankX`` dir;
+ - *branch*, *channel*, *slot* - typically used on FB-DIMM memory
+ controllers;
+ - *channel*, *slot* - used on Nehalem and newer Intel drivers.
+
+- ``dimm_mem_type`` - Memory Type attribute file
+
+ This attribute file will display what type of memory is currently
+ on this csrow. Normally, either buffered or unbuffered memory.
+ Examples:
+
+ - Registered-DDR
+ - Unbuffered-DDR
+
+.. [#f5] On some systems, the memory controller doesn't have any logic
+ to identify the memory module. On such systems, the directory is called ``rankX``.
+ On modern Intel memory controllers, the memory controller identifies the
+ memory modules directly. On such systems, the directory is called ``dimmX``.
+
+.. [#f6] There are also some ``power`` directories and ``subsystem``
+ symlinks inside the sysfs mapping that are automatically created by
+ the sysfs subsystem. Currently, they serve no purpose.
+
+
+System Logging
+--------------
+
+If logging for UEs and CEs is enabled, then system logs will contain
+information indicating that errors have been detected::
+
+ EDAC MC0: CE page 0x283, offset 0xce0, grain 8, syndrome 0x6ec3, row 0, channel 1 "DIMM_B1": amd76x_edac
+ EDAC MC0: CE page 0x1e5, offset 0xfb0, grain 8, syndrome 0xb741, row 0, channel 1 "DIMM_B1": amd76x_edac
+
+
+The structure of the message is:
+
+ +---------------------------------------+-------------+
+ | Content | Example |
+ +=======================================+=============+
+ | The memory controller | MC0 |
+ +---------------------------------------+-------------+
+ | Error type | CE |
+ +---------------------------------------+-------------+
+ | Memory page | 0x283 |
+ +---------------------------------------+-------------+
+ | Offset in the page | 0xce0 |
+ +---------------------------------------+-------------+
+ | The byte granularity | grain 8 |
+ | or resolution of the error | |
+ +---------------------------------------+-------------+
+ | The error syndrome | 0xb741 |
+ +---------------------------------------+-------------+
+ | Memory row | row 0 |
+ +---------------------------------------+-------------+
+ | Memory channel | channel 1 |
+ +---------------------------------------+-------------+
+ | DIMM label, if set prior | DIMM B1 |
+ +---------------------------------------+-------------+
+ | And then an optional, driver-specific | |
+ | message that may have additional | |
+ | information. | |
+ +---------------------------------------+-------------+
+
+Both UEs and CEs with no info will lack all but memory controller, error
+type, a notice of "no info" and then an optional, driver-specific error
+message.
+
+
+PCI Bus Parity Detection
+------------------------
+
+On Header Type 00 devices, the primary status is looked at for any
+parity error regardless of whether parity is enabled on the device or
+not. (The spec indicates parity is generated in some cases). On Header
+Type 01 bridges, the secondary status register is also looked at to see
+if parity occurred on the bus on the other side of the bridge.
+
+
+Sysfs configuration
+-------------------
+
+Under ``/sys/devices/system/edac/pci`` are control and attribute files as
+follows:
+
+
+- ``check_pci_parity`` - Enable/Disable PCI Parity checking control file
+
+ This control file enables or disables the PCI Bus Parity scanning
+ operation. Writing a 1 to this file enables the scanning. Writing
+ a 0 to this file disables the scanning.
+
+ Enable::
+
+ echo "1" >/sys/devices/system/edac/pci/check_pci_parity
+
+ Disable::
+
+ echo "0" >/sys/devices/system/edac/pci/check_pci_parity
+
+
+- ``pci_parity_count`` - Parity Count
+
+ This attribute file will display the number of parity errors that
+ have been detected.
+
+
+Module parameters
+-----------------
+
+- ``edac_mc_panic_on_ue`` - Panic on UE control file
+
+ An uncorrectable error will cause a machine panic. This is usually
+ desirable. It is a bad idea to continue when an uncorrectable error
+ occurs - it is indeterminate what was uncorrected and the operating
+ system context might be so mangled that continuing will lead to further
+ corruption. If the kernel has MCE configured, then EDAC will never
+ notice the UE.
+
+ LOAD TIME::
+
+ module/kernel parameter: edac_mc_panic_on_ue=[0|1]
+
+ RUN TIME::
+
+ echo "1" > /sys/module/edac_core/parameters/edac_mc_panic_on_ue
+
+
+- ``edac_mc_log_ue`` - Log UE control file
+
+
+ Generate kernel messages describing uncorrectable errors. These errors
+ are reported through the system message log system. UE statistics
+ will be accumulated even when UE logging is disabled.
+
+ LOAD TIME::
+
+ module/kernel parameter: edac_mc_log_ue=[0|1]
+
+ RUN TIME::
+
+ echo "1" > /sys/module/edac_core/parameters/edac_mc_log_ue
+
+
+- ``edac_mc_log_ce`` - Log CE control file
+
+
+ Generate kernel messages describing correctable errors. These
+ errors are reported through the system message log system.
+ CE statistics will be accumulated even when CE logging is disabled.
+
+ LOAD TIME::
+
+ module/kernel parameter: edac_mc_log_ce=[0|1]
+
+ RUN TIME::
+
+ echo "1" > /sys/module/edac_core/parameters/edac_mc_log_ce
+
+
+- ``edac_mc_poll_msec`` - Polling period control file
+
+
+ The time period, in milliseconds, for polling for error information.
+ Too small a value wastes resources. Too large a value might delay
+ necessary handling of errors and might loose valuable information for
+ locating the error. 1000 milliseconds (once each second) is the current
+ default. Systems which require all the bandwidth they can get, may
+ increase this.
+
+ LOAD TIME::
+
+ module/kernel parameter: edac_mc_poll_msec=[0|1]
+
+ RUN TIME::
+
+ echo "1000" > /sys/module/edac_core/parameters/edac_mc_poll_msec
+
+
+- ``panic_on_pci_parity`` - Panic on PCI PARITY Error
+
+
+ This control file enables or disables panicking when a parity
+ error has been detected.
+
+
+ module/kernel parameter::
+
+ edac_panic_on_pci_pe=[0|1]
+
+ Enable::
+
+ echo "1" > /sys/module/edac_core/parameters/edac_panic_on_pci_pe
+
+ Disable::
+
+ echo "0" > /sys/module/edac_core/parameters/edac_panic_on_pci_pe
+
+
+
+EDAC device type
+----------------
+
+In the header file, edac_pci.h, there is a series of edac_device structures
+and APIs for the EDAC_DEVICE.
+
+User space access to an edac_device is through the sysfs interface.
+
+At the location ``/sys/devices/system/edac`` (sysfs) new edac_device devices
+will appear.
+
+There is a three level tree beneath the above ``edac`` directory. For example,
+the ``test_device_edac`` device (found at the http://bluesmoke.sourceforget.net
+website) installs itself as::
+
+ /sys/devices/system/edac/test-instance
+
+in this directory are various controls, a symlink and one or more ``instance``
+directories.
+
+The standard default controls are:
+
+ ============== =======================================================
+ log_ce boolean to log CE events
+ log_ue boolean to log UE events
+ panic_on_ue boolean to ``panic`` the system if an UE is encountered
+ (default off, can be set true via startup script)
+ poll_msec time period between POLL cycles for events
+ ============== =======================================================
+
+The test_device_edac device adds at least one of its own custom control:
+
+ ============== ==================================================
+ test_bits which in the current test driver does nothing but
+ show how it is installed. A ported driver can
+ add one or more such controls and/or attributes
+ for specific uses.
+ One out-of-tree driver uses controls here to allow
+ for ERROR INJECTION operations to hardware
+ injection registers
+ ============== ==================================================
+
+The symlink points to the 'struct dev' that is registered for this edac_device.
+
+Instances
+---------
+
+One or more instance directories are present. For the ``test_device_edac``
+case:
+
+ +----------------+
+ | test-instance0 |
+ +----------------+
+
+
+In this directory there are two default counter attributes, which are totals of
+counter in deeper subdirectories.
+
+ ============== ====================================
+ ce_count total of CE events of subdirectories
+ ue_count total of UE events of subdirectories
+ ============== ====================================
+
+Blocks
+------
+
+At the lowest directory level is the ``block`` directory. There can be 0, 1
+or more blocks specified in each instance:
+
+ +-------------+
+ | test-block0 |
+ +-------------+
+
+In this directory the default attributes are:
+
+ ============== ================================================
+ ce_count which is counter of CE events for this ``block``
+ of hardware being monitored
+ ue_count which is counter of UE events for this ``block``
+ of hardware being monitored
+ ============== ================================================
+
+
+The ``test_device_edac`` device adds 4 attributes and 1 control:
+
+ ================== ====================================================
+ test-block-bits-0 for every POLL cycle this counter
+ is incremented
+ test-block-bits-1 every 10 cycles, this counter is bumped once,
+ and test-block-bits-0 is set to 0
+ test-block-bits-2 every 100 cycles, this counter is bumped once,
+ and test-block-bits-1 is set to 0
+ test-block-bits-3 every 1000 cycles, this counter is bumped once,
+ and test-block-bits-2 is set to 0
+ ================== ====================================================
+
+
+ ================== ====================================================
+ reset-counters writing ANY thing to this control will
+ reset all the above counters.
+ ================== ====================================================
+
+
+Use of the ``test_device_edac`` driver should enable any others to create their own
+unique drivers for their hardware systems.
+
+The ``test_device_edac`` sample driver is located at the
+http://bluesmoke.sourceforge.net project site for EDAC.
+
+
+Usage of EDAC APIs on Nehalem and newer Intel CPUs
+--------------------------------------------------
+
+On older Intel architectures, the memory controller was part of the North
+Bridge chipset. Nehalem, Sandy Bridge, Ivy Bridge, Haswell, Sky Lake and
+newer Intel architectures integrated an enhanced version of the memory
+controller (MC) inside the CPUs.
+
+This chapter will cover the differences of the enhanced memory controllers
+found on newer Intel CPUs, such as ``i7core_edac``, ``sb_edac`` and
+``sbx_edac`` drivers.
+
+.. note::
+
+ The Xeon E7 processor families use a separate chip for the memory
+ controller, called Intel Scalable Memory Buffer. This section doesn't
+ apply for such families.
+
+1) There is one Memory Controller per Quick Patch Interconnect
+ (QPI). At the driver, the term "socket" means one QPI. This is
+ associated with a physical CPU socket.
+
+ Each MC have 3 physical read channels, 3 physical write channels and
+ 3 logic channels. The driver currently sees it as just 3 channels.
+ Each channel can have up to 3 DIMMs.
+
+ The minimum known unity is DIMMs. There are no information about csrows.
+ As EDAC API maps the minimum unity is csrows, the driver sequentially
+ maps channel/DIMM into different csrows.
+
+ For example, supposing the following layout::
+
+ Ch0 phy rd0, wr0 (0x063f4031): 2 ranks, UDIMMs
+ dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
+ dimm 1 1024 Mb offset: 4, bank: 8, rank: 1, row: 0x4000, col: 0x400
+ Ch1 phy rd1, wr1 (0x063f4031): 2 ranks, UDIMMs
+ dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
+ Ch2 phy rd3, wr3 (0x063f4031): 2 ranks, UDIMMs
+ dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
+
+ The driver will map it as::
+
+ csrow0: channel 0, dimm0
+ csrow1: channel 0, dimm1
+ csrow2: channel 1, dimm0
+ csrow3: channel 2, dimm0
+
+ exports one DIMM per csrow.
+
+ Each QPI is exported as a different memory controller.
+
+2) The MC has the ability to inject errors to test drivers. The drivers
+ implement this functionality via some error injection nodes:
+
+ For injecting a memory error, there are some sysfs nodes, under
+ ``/sys/devices/system/edac/mc/mc?/``:
+
+ - ``inject_addrmatch/*``:
+ Controls the error injection mask register. It is possible to specify
+ several characteristics of the address to match an error code::
+
+ dimm = the affected dimm. Numbers are relative to a channel;
+ rank = the memory rank;
+ channel = the channel that will generate an error;
+ bank = the affected bank;
+ page = the page address;
+ column (or col) = the address column.
+
+ each of the above values can be set to "any" to match any valid value.
+
+ At driver init, all values are set to any.
+
+ For example, to generate an error at rank 1 of dimm 2, for any channel,
+ any bank, any page, any column::
+
+ echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
+ echo 1 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
+
+ To return to the default behaviour of matching any, you can do::
+
+ echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
+ echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
+
+ - ``inject_eccmask``:
+ specifies what bits will have troubles,
+
+ - ``inject_section``:
+ specifies what ECC cache section will get the error::
+
+ 3 for both
+ 2 for the highest
+ 1 for the lowest
+
+ - ``inject_type``:
+ specifies the type of error, being a combination of the following bits::
+
+ bit 0 - repeat
+ bit 1 - ecc
+ bit 2 - parity
+
+ - ``inject_enable``:
+ starts the error generation when something different than 0 is written.
+
+ All inject vars can be read. root permission is needed for write.
+
+ Datasheet states that the error will only be generated after a write on an
+ address that matches inject_addrmatch. It seems, however, that reading will
+ also produce an error.
+
+ For example, the following code will generate an error for any write access
+ at socket 0, on any DIMM/address on channel 2::
+
+ echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/channel

+ For socket 1, it is needed to replace "mc0" by "mc1" at the above

+
+ The generated error message will look like::
+
+ EDAC MC0: UE row 0, channel-a= 0 channel-b= 0 labels "-": NON_FATAL (addr = 0x0075b980, socket=0, Dimm=0, Channel=2, syndrome=0x00000040, count=1, Err=8c0000400001009f:4000080482 (read error: read ECC error))
+
+3) Corrected Error memory register counters
+
+ Those newer MCs have some registers to count memory errors. The driver
+ uses those registers to report Corrected Errors on devices with Registered
+ DIMMs.
+
+ However, those counters don't work with Unregistered DIMM. As the chipset
+ offers some counters that also work with UDIMMs (but with a worse level of
+ granularity than the default ones), the driver exposes those registers for
+ UDIMM memories.
+
+ They can be read by looking at the contents of ``all_channel_counts/``::
+
+ $ for i in /sys/devices/system/edac/mc/mc0/all_channel_counts/*; do echo $i; cat $i; done
+ /sys/devices/system/edac/mc/mc0/all_channel_counts/udimm0
+ 0
+ /sys/devices/system/edac/mc/mc0/all_channel_counts/udimm1
+ 0
+ /sys/devices/system/edac/mc/mc0/all_channel_counts/udimm2
+ 0
+
+ What happens here is that errors on different csrows, but at the same
+ dimm number will increment the same counter.
+ So, in this memory mapping::
+
+ csrow0: channel 0, dimm0
+ csrow1: channel 0, dimm1
+ csrow2: channel 1, dimm0
+ csrow3: channel 2, dimm0
+
+ The hardware will increment udimm0 for an error at the first dimm at either
+ csrow0, csrow2 or csrow3;
+
+ The hardware will increment udimm1 for an error at the second dimm at either
+ csrow0, csrow2 or csrow3;
+
+ The hardware will increment udimm2 for an error at the third dimm at either
+ csrow0, csrow2 or csrow3;
+
+4) Standard error counters
+
+ The standard error counters are generated when an mcelog error is received
+ by the driver. Since, with UDIMM, this is counted by software, it is
+ possible that some errors could be lost. With RDIMM's, they display the
+ contents of the registers

+Zoned Loop Block Device
+=======================
+
+.. Contents:
+
+ 1) Overview
+ 2) Creating a Zoned Device
+ 3) Deleting a Zoned Device
+ 4) Example
+
+
+1) Overview
+-----------
+
+The zoned loop block device driver (zloop) allows a user to create a zoned block
+device using one regular file per zone as backing storage. This driver does not
+directly control any hardware and uses read, write and truncate operations to
+regular files of a file system to emulate a zoned block device.
+
+Using zloop, zoned block devices with a configurable capacity, zone size and
+number of conventional zones can be created. The storage for each zone of the
+device is implemented using a regular file with a maximum size equal to the zone
+size. The size of a file backing a conventional zone is always equal to the zone
+size. The size of a file backing a sequential zone indicates the amount of data
+sequentially written to the file, that is, the size of the file directly
+indicates the position of the write pointer of the zone.
+
+When resetting a sequential zone, its backing file size is truncated to zero.
+Conversely, for a zone finish operation, the backing file is truncated to the
+zone size. With this, the maximum capacity of a zloop zoned block device created
+can be larger configured to be larger than the storage space available on the
+backing file system. Of course, for such configuration, writing more data than
+the storage space available on the backing file system will result in write
+errors.
+
+The zoned loop block device driver implements a complete zone transition state
+machine. That is, zones can be empty, implicitly opened, explicitly opened,
+closed or full. The current implementation does not support any limits on the
+maximum number of open and active zones.
+
+No user tools are necessary to create and delete zloop devices.
+
+2) Creating a Zoned Device
+--------------------------
+
+Once the zloop module is loaded (or if zloop is compiled in the kernel), the
+character device file /dev/zloop-control can be used to add a zloop device.
+This is done by writing an "add" command directly to the /dev/zloop-control
+device::
+
+ $ modprobe zloop
+ $ ls -l /dev/zloop*
+ crw-------. 1 root root 10, 123 Jan 6 19:18 /dev/zloop-control
+
+ $ mkdir -p <base directory/<device ID>
+ $ echo "add [options]" > /dev/zloop-control
+
+The options available for the add command can be listed by reading the
+/dev/zloop-control device::
+
+ $ cat /dev/zloop-control
+ add id=%d,capacity_mb=%u,zone_size_mb=%u,zone_capacity_mb=%u,conv_zones=%u,base_dir=%s,nr_queues=%u,queue_depth=%u,buffered_io
+ remove id=%d
+
+In more details, the options that can be used with the "add" command are as
+follows.
+
+=================== =========================================================
+id Device number (the X in /dev/zloopX).
+ Default: automatically assigned.
+capacity_mb Device total capacity in MiB. This is always rounded up
+ to the nearest higher multiple of the zone size.
+ Default: 16384 MiB (16 GiB).
+zone_size_mb Device zone size in MiB. Default: 256 MiB.
+zone_capacity_mb Device zone capacity (must always be equal to or lower
+ than the zone size. Default: zone size.
+conv_zones Total number of conventioanl zones starting from
+ sector 0
+ Default: 8
+base_dir Path to the base directory where to create the directory
+ containing the zone files of the device.
+ Default=/var/local/zloop.
+ The device directory containing the zone files is always
+ named with the device ID. E.g. the default zone file
+ directory for /dev/zloop0 is /var/local/zloop/0.
+nr_queues Number of I/O queues of the zoned block device. This
+ value is always capped by the number of online CPUs
+ Default: 1
+queue_depth Maximum I/O queue depth per I/O queue.
+ Default: 64
+buffered_io Do buffered IOs instead of direct IOs (default: false)
+zone_append Enable or disable a zloop device native zone append
+ support.
+ Default: 1 (enabled).
+ If native zone append support is disabled, the block layer
+ will emulate this operation using regular write
+ operations.
+ordered_zone_append Enable zloop mitigation of zone append reordering.
+ Default: disabled.
+ This is useful for testing file systems file data mapping
+ (extents), as when enabled, this can significantly reduce
+ the number of data extents needed to for a file data
+ mapping.
+=================== =========================================================
+
+3) Deleting a Zoned Device
+--------------------------
+
+Deleting an unused zoned loop block device is done by issuing the "remove"
+command to /dev/zloop-control, specifying the ID of the device to remove::
+
+ $ echo "remove id=X" > /dev/zloop-control
+
+The remove command does not have any option.
+
+A zoned device that was removed can be re-added again without any change to the
+state of the device zones: the device zones are restored to their last state
+before the device was removed. Adding again a zoned device after it was removed
+must always be done using the same configuration as when the device was first
+added. If a zone configuration change is detected, an error will be returned and
+the zoned device will not be created.
+
+To fully delete a zoned device, after executing the remove operation, the device
+base directory containing the backing files of the device zones must be deleted.
+
+4) Example
+----------
+
+The following sequence of commands creates a 2GB zoned device with zones of 64
+MB and a zone capacity of 63 MB::
+
+ $ modprobe zloop
+ $ mkdir -p /var/local/zloop/0
+ $ echo "add capacity_mb=2048,zone_size_mb=64,zone_capacity=63MB" > /dev/zloop-control
+
+For the device created (/dev/zloop0), the zone backing files are all created
+under the default base directory (/var/local/zloop)::
+
+ $ ls -l /var/local/zloop/0
+ total 0
+ -rw-------. 1 root root 67108864 Jan 6 22:23 cnv-000000

+=================================================
+
+Compression algorithms may support specific parameters which can be

+attribute which provides a per-algorithm params configuration.
+
+For example, several compression algorithms support `level` parameter.
+In addition, certain compression algorithms support pre-trained dictionaries,

+ echo "algo=zstd level=8 dict=/etc/dictionary" > \
+ /sys/block/zram0/algorithm_params
+
+Parameters are algorithm specific: not all algorithms support pre-trained
+dictionaries, not all algorithms support `level`. Furthermore, for certain
+algorithms `level` controls the compression level (the higher the value the
+better the compression ratio, it even can take negatives values for some
+algorithms), for other algorithms `level` is acceleration level (the higher

+Bisecting a regression
+======================
-Introduction
-============
+This document describes how to use a ``git bisect`` to find the source code
+change that broke something -- for example when some functionality stopped
+working after upgrading from Linux 6.0 to 6.1.
-Always try the latest kernel from kernel.org and build from source. If you are
-not confident in doing that please report the bug to your distribution vendor
-instead of to a kernel developer.
+The text focuses on the gist of the process. If you are new to bisecting the
+kernel, better follow Documentation/admin-guide/verify-bugs-and-bisect-regressions.rst
+instead: it depicts everything from start to finish while covering multiple
+aspects even kernel developers occasionally forget. This includes detecting
+situations early where a bisection would be a waste of time, as nobody would
+care about the result -- for example, because the problem happens after the
+kernel marked itself as 'tainted', occurs in an abandoned version, was already
+fixed, or is caused by a .config change you or your Linux distributor performed.
-Finding bugs is not always easy. Have a go though. If you can't find it don't
-give up. Report as much as you have found to the relevant maintainer. See
-MAINTAINERS for who that is for the subsystem you have worked on.
+Finding the change causing a kernel issue using a bisection
+===========================================================
-Before you submit a bug report read
-'Documentation/admin-guide/reporting-issues.rst'.
+*Note: the following process assumes you prepared everything for a bisection.
+This includes having a Git clone with the appropriate sources, installing the
+software required to build and install kernels, as well as a .config file stored
+in a safe place (the following example assumes '~/prepared_kernel_.config') to
+use as pristine base at each bisection step; ideally, you have also worked out
+a fully reliable and straight-forward way to reproduce the regression, too.*
-Devices not appearing
-=====================
+* Preparation: start the bisection and tell Git about the points in the history
+ you consider to be working and broken, which Git calls 'good' and 'bad'::
-Often this is caused by udev/systemd. Check that first before blaming it
-on the kernel.
+ git bisect start
+ git bisect good v6.0
+ git bisect bad v6.1
-Finding patch that caused a bug
-===============================
+ Instead of Git tags like 'v6.0' and 'v6.1' you can specify commit-ids, too.
-Using the provided tools with ``git`` makes finding bugs easy provided the bug
-is reproducible.
+1. Copy your prepared .config into the build directory and adjust it to the
+ needs of the codebase Git checked out for testing::
-Steps to do it:
+ cp ~/prepared_kernel_.config .config
+ make olddefconfig
-- build the Kernel from its git source
-- start bisect with [#f1]_::
-
- $ git bisect start
-
-- mark the broken changeset with::
-
- $ git bisect bad [commit]
-
-- mark a changeset where the code is known to work with::
-
- $ git bisect good [commit]
-
-- rebuild the Kernel and test
-- interact with git bisect by using either::
-
- $ git bisect good
-
- or::
-
- $ git bisect bad
-
- depending if the bug happened on the changeset you're testing
-- After some interactions, git bisect will give you the changeset that
- likely caused the bug.
-
-- For example, if you know that the current version is bad, and version
- 4.8 is good, you could do::
-
- $ git bisect start
- $ git bisect bad # Current version is bad
- $ git bisect good v4.8
-
-
-.. [#f1] You can, optionally, provide both good and bad arguments at git
- start with ``git bisect start [BAD] [GOOD]``
-
-For further references, please read:
-
-- The man page for ``git-bisect``
-- `Fighting regressions with git bisect <https://www.kernel.org/pub/software/scm/git/docs/git-bisect-lk2009.html>`_
-- `Fully automated bisecting with "git bisect run" <https://lwn.net/Articles/317154>`_
-- `Using Git bisect to figure out when brokenness was introduced <http://webchick.net/node/99>`_
+2. Now build, install, and boot a kernel. This might fail for unrelated reasons,
+ for example, when a compile error happens at the current stage of the
+ bisection a later change resolves. In such cases run ``git bisect skip`` and
+ go back to step 1.
+
+3. Check if the functionality that regressed works in the kernel you just built.
+
+ If it works, execute::
+
+ git bisect good
+
+ If it is broken, run::
+
+ git bisect bad
+
+ Note, getting this wrong just once will send the rest of the bisection
+ totally off course. To prevent having to start anew later you thus want to
+ ensure what you tell Git is correct; it is thus often wise to spend a few
+ minutes more on testing in case your reproducer is unreliable.
+
+ After issuing one of these two commands, Git will usually check out another
+ bisection point and print something like 'Bisecting: 675 revisions left to
+ test after this (roughly 10 steps)'. In that case go back to step 1.
+
+ If Git instead prints something like 'cafecaca0c0dacafecaca0c0dacafecaca0c0da
+ is the first bad commit', then you have finished the bisection. In that case
+ move to the next point below. Note, right after displaying that line Git will
+ show some details about the culprit including its patch description; this can
+ easily fill your terminal, so you might need to scroll up to see the message
+ mentioning the culprit's commit-id.
+
+ In case you missed Git's output, you can always run ``git bisect log`` to
+ print the status: it will show how many steps remain or mention the result of
+ the bisection.
+
+* Recommended complementary task: put the bisection log and the current .config
+ file aside for the bug report; furthermore tell Git to reset the sources to
+ the state before the bisection::
+
+ git bisect log > ~/bisection-log
+ cp .config ~/bisection-config-culprit
+ git bisect reset
+
+* Recommended optional task: try reverting the culprit on top of the latest
+ codebase and check if that fixes your bug; if that is the case, it validates
+ the bisection and enables developers to resolve the regression through a
+ revert.
+
+ To try this, update your clone and check out latest mainline. Then tell Git
+ to revert the change by specifying its commit-id::
+
+ git revert --no-edit cafec0cacaca0
+
+ Git might reject this, for example when the bisection landed on a merge
+ commit. In that case, abandon the attempt. Do the same, if Git fails to revert
+ the culprit on its own because later changes depend on it -- at least unless
+ you bisected a stable or longterm kernel series, in which case you want to
+ check out its latest codebase and try a revert there.
+
+ If a revert succeeds, build and test another kernel to check if reverting
+ resolved your regression.
+
+With that the process is complete. Now report the regression as described by
+Documentation/admin-guide/reporting-issues.rst.
+
+Bisecting linux-next
+--------------------
+
+If you face a problem only happening in linux-next, bisect between the
+linux-next branches 'stable' and 'master'. The following commands will start
+the process for a linux-next tree you added as a remote called 'next'::
+
+ git bisect start
+ git bisect good next/stable
+ git bisect bad next/master
+
+The 'stable' branch refers to the state of linux-mainline that the current
+linux-next release (found in the 'master' branch) is based on -- the former
+thus should be free of any problems that show up in -next, but not in Linus'
+tree.
+
+This will bisect across a wide range of changes, some of which you might have
+used in earlier linux-next releases without problems. Sadly there is no simple
+way to avoid checking them: bisecting from one linux-next release to a later
+one (say between 'next-20241020' and 'next-20241021') is impossible, as they
+share no common history.

+ Specifically, when a new HugeTLB folio is allocated to

+ actually used (for e.g at page fault time). Host memory
+ overcommit management has to consider this when configuring

+ done via other mechanisms (such as the HugeTLB controller).
+ * Failure to charge a HugeTLB folio to the memory controller
+ results in SIGBUS. This could happen even if the HugeTLB pool
+ still has pages available (but the cgroup limit is hit and
+ reclaim attempt fails).
+ * Charging HugeTLB memory towards the memory controller affects
+ memory protection and reclaim dynamics. Any userspace tuning

+to the target of the reclaim (i.e. any of memory cgroup limits, proactive

+dm-pcache — Persistent Cache
+=================================
+
+*Author: Dongsheng Yang <dongsheng.yang@linux.dev>*
+
+This document describes *dm-pcache*, a Device-Mapper target that lets a
+byte-addressable *DAX* (persistent-memory, “pmem”) region act as a
+high-performance, crash-persistent cache in front of a slower block
+device. The code lives in `drivers/md/dm-pcache/`.
+
+Quick feature summary
+=====================
+
+* *Write-back* caching (only mode currently supported).
+* *16 MiB segments* allocated on the pmem device.
+* *Data CRC32* verification (optional, per cache).
+* Crash-safe: every metadata structure is duplicated (`PCACHE_META_INDEX_MAX
+ == 2`) and protected with CRC+sequence numbers.
+* *Multi-tree indexing* (indexing trees sharded by logical address) for high PMem parallelism
+* Pure *DAX path* I/O – no extra BIO round-trips
+* *Log-structured write-back* that preserves backend crash-consistency
+

+Segments and key-sets
+---------------------
+
+* The pmem space is divided into *16 MiB segments*.
+* Each write allocates space from a per-CPU *data_head* inside a segment.
+* A *cache-key* records a logical range on the origin and where it lives
+ inside pmem (segment + offset + generation).
+* 128 keys form a *key-set* (kset); ksets are written sequentially in pmem
+ and are themselves crash-safe (CRC).
+* The pair *(key_tail, dirty_tail)* delimit clean/dirty and live/dead ksets.
+
+Write-back
+----------
+
+Dirty keys are queued into a tree; a background worker copies data
+back to the backing_dev and advances *dirty_tail*. A FLUSH/FUA bio from the
+upper layers forces an immediate metadata commit.
+
+Garbage collection
+------------------
+
+GC starts when ``segs_used >= seg_total * gc_percent / 100``. It walks
+from *key_tail*, frees segments whose every key has been invalidated, and
+advances *key_tail*.
+
+CRC verification
+----------------
+
+If ``data_crc is enabled`` dm-pcache computes a CRC32 over every cached data
+range when it is inserted and stores it in the on-media key. Reads
+validate the CRC before copying to the caller.
+
+
+Failure handling
+================
+
+* *pmem media errors* – all metadata copies are read with
+ ``copy_mc_to_kernel``; an uncorrectable error logs and aborts initialisation.
+* *Cache full* – if no free segment can be found, writes return ``-EBUSY``;
+ dm-pcache retries internally (request deferral).
+* *System crash* – on attach, the driver replays ksets from *key_tail* to
+ rebuild the in-core trees; every segment’s generation guards against
+ use-after-free keys.
+
+
+Limitations & TODO
+==================
+
+* Only *write-back* mode; other modes planned.
+* Only FIFO cache invalidate; other (LRU, ARC...) planned.
+* Table reload is not supported currently.
+* Discard planned.
+
+
+Example workflow

+================
+Design of dm-vdo
+================
+
+The dm-vdo (virtual data optimizer) target provides inline deduplication,
+compression, zero-block elimination, and thin provisioning. A dm-vdo target
+can be backed by up to 256TB of storage, and can present a logical size of
+up to 4PB. This target was originally developed at Permabit Technology
+Corp. starting in 2009. It was first released in 2013 and has been used in
+production environments ever since. It was made open-source in 2017 after
+Permabit was acquired by Red Hat. This document describes the design of
+dm-vdo. For usage, see vdo.rst in the same directory as this file.
+
+Because deduplication rates fall drastically as the block size increases, a
+vdo target has a maximum block size of 4K. However, it can achieve
+deduplication rates of 254:1, i.e. up to 254 copies of a given 4K block can
+reference a single 4K of actual storage. It can achieve compression rates
+of 14:1. All zero blocks consume no storage at all.
+
+Theory of Operation
+===================
+
+The design of dm-vdo is based on the idea that deduplication is a two-part
+problem. The first is to recognize duplicate data. The second is to avoid
+storing multiple copies of those duplicates. Therefore, dm-vdo has two main
+parts: a deduplication index (called UDS) that is used to discover
+duplicate data, and a data store with a reference counted block map that
+maps from logical block addresses to the actual storage location of the
+data.
+
+Zones and Threading
+-------------------
+
+Due to the complexity of data optimization, the number of metadata
+structures involved in a single write operation to a vdo target is larger
+than most other targets. Furthermore, because vdo must operate on small
+block sizes in order to achieve good deduplication rates, acceptable
+performance can only be achieved through parallelism. Therefore, vdo's
+design attempts to be lock-free.
+
+Most of a vdo's main data structures are designed to be easily divided into
+"zones" such that any given bio must only access a single zone of any zoned
+structure. Safety with minimal locking is achieved by ensuring that during
+normal operation, each zone is assigned to a specific thread, and only that
+thread will access the portion of the data structure in that zone.
+Associated with each thread is a work queue. Each bio is associated with a
+request object (the "data_vio") which will be added to a work queue when
+the next phase of its operation requires access to the structures in the
+zone associated with that queue.
+
+Another way of thinking about this arrangement is that the work queue for
+each zone has an implicit lock on the structures it manages for all its
+operations, because vdo guarantees that no other thread will alter those
+structures.
+
+Although each structure is divided into zones, this division is not
+reflected in the on-disk representation of each data structure. Therefore,
+the number of zones for each structure, and hence the number of threads,
+can be reconfigured each time a vdo target is started.
+
+The Deduplication Index
+-----------------------
+
+In order to identify duplicate data efficiently, vdo was designed to
+leverage some common characteristics of duplicate data. From empirical
+observations, we gathered two key insights. The first is that in most data
+sets with significant amounts of duplicate data, the duplicates tend to
+have temporal locality. When a duplicate appears, it is more likely that
+other duplicates will be detected, and that those duplicates will have been
+written at about the same time. This is why the index keeps records in
+temporal order. The second insight is that new data is more likely to
+duplicate recent data than it is to duplicate older data and in general,
+there are diminishing returns to looking further back in time. Therefore,
+when the index is full, it should cull its oldest records to make space for
+new ones. Another important idea behind the design of the index is that the
+ultimate goal of deduplication is to reduce storage costs. Since there is a
+trade-off between the storage saved and the resources expended to achieve
+those savings, vdo does not attempt to find every last duplicate block. It
+is sufficient to find and eliminate most of the redundancy.
+
+Each block of data is hashed to produce a 16-byte block name. An index
+record consists of this block name paired with the presumed location of
+that data on the underlying storage. However, it is not possible to
+guarantee that the index is accurate. In the most common case, this occurs
+because it is too costly to update the index when a block is over-written
+or discarded. Doing so would require either storing the block name along
+with the blocks, which is difficult to do efficiently in block-based
+storage, or reading and rehashing each block before overwriting it.
+Inaccuracy can also result from a hash collision where two different blocks
+have the same name. In practice, this is extremely unlikely, but because
+vdo does not use a cryptographic hash, a malicious workload could be
+constructed. Because of these inaccuracies, vdo treats the locations in the
+index as hints, and reads each indicated block to verify that it is indeed
+a duplicate before sharing the existing block with a new one.
+
+Records are collected into groups called chapters. New records are added to
+the newest chapter, called the open chapter. This chapter is stored in a
+format optimized for adding and modifying records, and the content of the
+open chapter is not finalized until it runs out of space for new records.
+When the open chapter fills up, it is closed and a new open chapter is
+created to collect new records.
+
+Closing a chapter converts it to a different format which is optimized for
+reading. The records are written to a series of record pages based on the
+order in which they were received. This means that records with temporal
+locality should be on a small number of pages, reducing the I/O required to
+retrieve them. The chapter also compiles an index that indicates which
+record page contains any given name. This index means that a request for a
+name can determine exactly which record page may contain that record,
+without having to load the entire chapter from storage. This index uses
+only a subset of the block name as its key, so it cannot guarantee that an
+index entry refers to the desired block name. It can only guarantee that if
+there is a record for this name, it will be on the indicated page. Closed
+chapters are read-only structures and their contents are never altered in
+any way.
+
+Once enough records have been written to fill up all the available index
+space, the oldest chapter is removed to make space for new chapters. Any
+time a request finds a matching record in the index, that record is copied
+into the open chapter. This ensures that useful block names remain available
+in the index, while unreferenced block names are forgotten over time.
+
+In order to find records in older chapters, the index also maintains a
+higher level structure called the volume index, which contains entries
+mapping each block name to the chapter containing its newest record. This
+mapping is updated as records for the block name are copied or updated,
+ensuring that only the newest record for a given block name can be found.
+An older record for a block name will no longer be found even though it has
+not been deleted from its chapter. Like the chapter index, the volume index
+uses only a subset of the block name as its key and can not definitively
+say that a record exists for a name. It can only say which chapter would
+contain the record if a record exists. The volume index is stored entirely
+in memory and is saved to storage only when the vdo target is shut down.
+
+From the viewpoint of a request for a particular block name, it will first
+look up the name in the volume index. This search will either indicate that
+the name is new, or which chapter to search. If it returns a chapter, the
+request looks up its name in the chapter index. This will indicate either
+that the name is new, or which record page to search. Finally, if it is not
+new, the request will look for its name in the indicated record page.
+This process may require up to two page reads per request (one for the
+chapter index page and one for the request page). However, recently
+accessed pages are cached so that these page reads can be amortized across
+many block name requests.
+
+The volume index and the chapter indexes are implemented using a
+memory-efficient structure called a delta index. Instead of storing the
+entire block name (the key) for each entry, the entries are sorted by name
+and only the difference between adjacent keys (the delta) is stored.
+Because we expect the hashes to be randomly distributed, the size of the
+deltas follows an exponential distribution. Because of this distribution,
+the deltas are expressed using a Huffman code to take up even less space.
+The entire sorted list of keys is called a delta list. This structure
+allows the index to use many fewer bytes per entry than a traditional hash
+table, but it is slightly more expensive to look up entries, because a
+request must read every entry in a delta list to add up the deltas in order
+to find the record it needs. The delta index reduces this lookup cost by
+splitting its key space into many sub-lists, each starting at a fixed key
+value, so that each individual list is short.
+
+The default index size can hold 64 million records, corresponding to about
+256GB of data. This means that the index can identify duplicate data if the
+original data was written within the last 256GB of writes. This range is
+called the deduplication window. If new writes duplicate data that is older
+than that, the index will not be able to find it because the records of the
+older data have been removed. This means that if an application writes a
+200 GB file to a vdo target and then immediately writes it again, the two
+copies will deduplicate perfectly. Doing the same with a 500 GB file will
+result in no deduplication, because the beginning of the file will no
+longer be in the index by the time the second write begins (assuming there
+is no duplication within the file itself).
+
+If an application anticipates a data workload that will see useful
+deduplication beyond the 256GB threshold, vdo can be configured to use a
+larger index with a correspondingly larger deduplication window. (This
+configuration can only be set when the target is created, not altered
+later. It is important to consider the expected workload for a vdo target
+before configuring it.) There are two ways to do this.
+
+One way is to increase the memory size of the index, which also increases
+the amount of backing storage required. Doubling the size of the index will
+double the length of the deduplication window at the expense of doubling
+the storage size and the memory requirements.
+
+The other option is to enable sparse indexing. Sparse indexing increases
+the deduplication window by a factor of 10, at the expense of also
+increasing the storage size by a factor of 10. However with sparse
+indexing, the memory requirements do not increase. The trade-off is
+slightly more computation per request and a slight decrease in the amount
+of deduplication detected. For most workloads with significant amounts of
+duplicate data, sparse indexing will detect 97-99% of the deduplication
+that a standard index will detect.
+
+The vio and data_vio Structures
+-------------------------------
+
+A vio (short for Vdo I/O) is conceptually similar to a bio, with additional
+fields and data to track vdo-specific information. A struct vio maintains a
+pointer to a bio but also tracks other fields specific to the operation of
+vdo. The vio is kept separate from its related bio because there are many
+circumstances where vdo completes the bio but must continue to do work
+related to deduplication or compression.
+
+Metadata reads and writes, and other writes that originate within vdo, use
+a struct vio directly. Application reads and writes use a larger structure
+called a data_vio to track information about their progress. A struct
+data_vio contain a struct vio and also includes several other fields
+related to deduplication and other vdo features. The data_vio is the
+primary unit of application work in vdo. Each data_vio proceeds through a
+set of steps to handle the application data, after which it is reset and
+returned to a pool of data_vios for reuse.
+
+There is a fixed pool of 2048 data_vios. This number was chosen to bound
+the amount of work that is required to recover from a crash. In addition,
+benchmarks have indicated that increasing the size of the pool does not
+significantly improve performance.
+
+The Data Store
+--------------
+
+The data store is implemented by three main data structures, all of which
+work in concert to reduce or amortize metadata updates across as many data
+writes as possible.
+
+*The Slab Depot*
+
+Most of the vdo volume belongs to the slab depot. The depot contains a
+collection of slabs. The slabs can be up to 32GB, and are divided into
+three sections. Most of a slab consists of a linear sequence of 4K blocks.
+These blocks are used either to store data, or to hold portions of the
+block map (see below). In addition to the data blocks, each slab has a set
+of reference counters, using 1 byte for each data block. Finally each slab
+has a journal.
+
+Reference updates are written to the slab journal. Slab journal blocks are
+written out either when they are full, or when the recovery journal
+requests they do so in order to allow the main recovery journal (see below)
+to free up space. The slab journal is used both to ensure that the main
+recovery journal can regularly free up space, and also to amortize the cost
+of updating individual reference blocks. The reference counters are kept in
+memory and are written out, a block at a time in oldest-dirtied-order, only
+when there is a need to reclaim slab journal space. The write operations
+are performed in the background as needed so they do not add latency to
+particular I/O operations.
+
+Each slab is independent of every other. They are assigned to "physical
+zones" in round-robin fashion. If there are P physical zones, then slab n
+is assigned to zone n mod P.
+
+The slab depot maintains an additional small data structure, the "slab
+summary," which is used to reduce the amount of work needed to come back
+online after a crash. The slab summary maintains an entry for each slab
+indicating whether or not the slab has ever been used, whether all of its
+reference count updates have been persisted to storage, and approximately
+how full it is. During recovery, each physical zone will attempt to recover
+at least one slab, stopping whenever it has recovered a slab which has some
+free blocks. Once each zone has some space, or has determined that none is
+available, the target can resume normal operation in a degraded mode. Read
+and write requests can be serviced, perhaps with degraded performance,
+while the remainder of the dirty slabs are recovered.
+
+*The Block Map*
+
+The block map contains the logical to physical mapping. It can be thought
+of as an array with one entry per logical address. Each entry is 5 bytes,
+36 bits of which contain the physical block number which holds the data for
+the given logical address. The other 4 bits are used to indicate the nature
+of the mapping. Of the 16 possible states, one represents a logical address
+which is unmapped (i.e. it has never been written, or has been discarded),
+one represents an uncompressed block, and the other 14 states are used to
+indicate that the mapped data is compressed, and which of the compression
+slots in the compressed block contains the data for this logical address.
+
+In practice, the array of mapping entries is divided into "block map
+pages," each of which fits in a single 4K block. Each block map page
+consists of a header and 812 mapping entries. Each mapping page is actually
+a leaf of a radix tree which consists of block map pages at each level.
+There are 60 radix trees which are assigned to "logical zones" in round
+robin fashion. (If there are L logical zones, tree n will belong to zone n
+mod L.) At each level, the trees are interleaved, so logical addresses
+0-811 belong to tree 0, logical addresses 812-1623 belong to tree 1, and so
+on. The interleaving is maintained all the way up to the 60 root nodes.
+Choosing 60 trees results in an evenly distributed number of trees per zone
+for a large number of possible logical zone counts. The storage for the 60
+tree roots is allocated at format time. All other block map pages are
+allocated out of the slabs as needed. This flexible allocation avoids the
+need to pre-allocate space for the entire set of logical mappings and also
+makes growing the logical size of a vdo relatively easy.
+
+In operation, the block map maintains two caches. It is prohibitive to keep
+the entire leaf level of the trees in memory, so each logical zone
+maintains its own cache of leaf pages. The size of this cache is
+configurable at target start time. The second cache is allocated at start
+time, and is large enough to hold all the non-leaf pages of the entire
+block map. This cache is populated as pages are needed.
+
+*The Recovery Journal*
+
+The recovery journal is used to amortize updates across the block map and
+slab depot. Each write request causes an entry to be made in the journal.
+Entries are either "data remappings" or "block map remappings." For a data
+remapping, the journal records the logical address affected and its old and
+new physical mappings. For a block map remapping, the journal records the
+block map page number and the physical block allocated for it. Block map
+pages are never reclaimed or repurposed, so the old mapping is always 0.
+
+Each journal entry is an intent record summarizing the metadata updates
+that are required for a data_vio. The recovery journal issues a flush
+before each journal block write to ensure that the physical data for the
+new block mappings in that block are stable on storage, and journal block
+writes are all issued with the FUA bit set to ensure the recovery journal
+entries themselves are stable. The journal entry and the data write it
+represents must be stable on disk before the other metadata structures may
+be updated to reflect the operation. These entries allow the vdo device to
+reconstruct the logical to physical mappings after an unexpected
+interruption such as a loss of power.
+
+*Write Path*
+
+All write I/O to vdo is asynchronous. Each bio will be acknowledged as soon
+as vdo has done enough work to guarantee that it can complete the write
+eventually. Generally, the data for acknowledged but unflushed write I/O
+can be treated as though it is cached in memory. If an application
+requires data to be stable on storage, it must issue a flush or write the
+data with the FUA bit set like any other asynchronous I/O. Shutting down
+the vdo target will also flush any remaining I/O.
+
+Application write bios follow the steps outlined below.
+
+1. A data_vio is obtained from the data_vio pool and associated with the
+ application bio. If there are no data_vios available, the incoming bio
+ will block until a data_vio is available. This provides back pressure
+ to the application. The data_vio pool is protected by a spin lock.
+
+ The newly acquired data_vio is reset and the bio's data is copied into
+ the data_vio if it is a write and the data is not all zeroes. The data
+ must be copied because the application bio can be acknowledged before
+ the data_vio processing is complete, which means later processing steps
+ will no longer have access to the application bio. The application bio
+ may also be smaller than 4K, in which case the data_vio will have
+ already read the underlying block and the data is instead copied over
+ the relevant portion of the larger block.
+
+2. The data_vio places a claim (the "logical lock") on the logical address
+ of the bio. It is vital to prevent simultaneous modifications of the
+ same logical address, because deduplication involves sharing blocks.
+ This claim is implemented as an entry in a hashtable where the key is
+ the logical address and the value is a pointer to the data_vio
+ currently handling that address.
+
+ If a data_vio looks in the hashtable and finds that another data_vio is
+ already operating on that logical address, it waits until the previous
+ operation finishes. It also sends a message to inform the current
+ lock holder that it is waiting. Most notably, a new data_vio waiting
+ for a logical lock will flush the previous lock holder out of the
+ compression packer (step 8d) rather than allowing it to continue
+ waiting to be packed.
+
+ This stage requires the data_vio to get an implicit lock on the
+ appropriate logical zone to prevent concurrent modifications of the
+ hashtable. This implicit locking is handled by the zone divisions
+ described above.
+
+3. The data_vio traverses the block map tree to ensure that all the
+ necessary internal tree nodes have been allocated, by trying to find
+ the leaf page for its logical address. If any interior tree page is
+ missing, it is allocated at this time out of the same physical storage
+ pool used to store application data.
+
+ a. If any page-node in the tree has not yet been allocated, it must be
+ allocated before the write can continue. This step requires the
+ data_vio to lock the page-node that needs to be allocated. This
+ lock, like the logical block lock in step 2, is a hashtable entry
+ that causes other data_vios to wait for the allocation process to
+ complete.
+
+ The implicit logical zone lock is released while the allocation is
+ happening, in order to allow other operations in the same logical
+ zone to proceed. The details of allocation are the same as in
+ step 4. Once a new node has been allocated, that node is added to
+ the tree using a similar process to adding a new data block mapping.
+ The data_vio journals the intent to add the new node to the block
+ map tree (step 10), updates the reference count of the new block
+ (step 11), and reacquires the implicit logical zone lock to add the
+ new mapping to the parent tree node (step 12). Once the tree is
+ updated, the data_vio proceeds down the tree. Any other data_vios
+ waiting on this allocation also proceed.
+
+ b. In the steady-state case, the block map tree nodes will already be
+ allocated, so the data_vio just traverses the tree until it finds
+ the required leaf node. The location of the mapping (the "block map
+ slot") is recorded in the data_vio so that later steps do not need
+ to traverse the tree again. The data_vio then releases the implicit
+ logical zone lock.
+
+4. If the block is a zero block, skip to step 9. Otherwise, an attempt is
+ made to allocate a free data block. This allocation ensures that the
+ data_vio can write its data somewhere even if deduplication and
+ compression are not possible. This stage gets an implicit lock on a
+ physical zone to search for free space within that zone.
+
+ The data_vio will search each slab in a zone until it finds a free
+ block or decides there are none. If the first zone has no free space,
+ it will proceed to search the next physical zone by taking the implicit
+ lock for that zone and releasing the previous one until it finds a
+ free block or runs out of zones to search. The data_vio will acquire a
+ struct pbn_lock (the "physical block lock") on the free block. The
+ struct pbn_lock also has several fields to record the various kinds of
+ claims that data_vios can have on physical blocks. The pbn_lock is
+ added to a hashtable like the logical block locks in step 2. This
+ hashtable is also covered by the implicit physical zone lock. The
+ reference count of the free block is updated to prevent any other
+ data_vio from considering it free. The reference counters are a
+ sub-component of the slab and are thus also covered by the implicit
+ physical zone lock.
+
+5. If an allocation was obtained, the data_vio has all the resources it
+ needs to complete the write. The application bio can safely be
+ acknowledged at this point. The acknowledgment happens on a separate
+ thread to prevent the application callback from blocking other data_vio
+ operations.
+
+ If an allocation could not be obtained, the data_vio continues to
+ attempt to deduplicate or compress the data, but the bio is not
+ acknowledged because the vdo device may be out of space.
+
+6. At this point vdo must determine where to store the application data.
+ The data_vio's data is hashed and the hash (the "record name") is
+ recorded in the data_vio.
+
+7. The data_vio reserves or joins a struct hash_lock, which manages all of
+ the data_vios currently writing the same data. Active hash locks are
+ tracked in a hashtable similar to the way logical block locks are
+ tracked in step 2. This hashtable is covered by the implicit lock on
+ the hash zone.
+
+ If there is no existing hash lock for this data_vio's record_name, the
+ data_vio obtains a hash lock from the pool, adds it to the hashtable,
+ and sets itself as the new hash lock's "agent." The hash_lock pool is
+ also covered by the implicit hash zone lock. The hash lock agent will
+ do all the work to decide where the application data will be
+ written. If a hash lock for the data_vio's record_name already exists,
+ and the data_vio's data is the same as the agent's data, the new
+ data_vio will wait for the agent to complete its work and then share
+ its result.
+
+ In the rare case that a hash lock exists for the data_vio's hash but
+ the data does not match the hash lock's agent, the data_vio skips to
+ step 8h and attempts to write its data directly. This can happen if two
+ different data blocks produce the same hash, for example.
+
+8. The hash lock agent attempts to deduplicate or compress its data with
+ the following steps.
+
+ a. The agent initializes and sends its embedded deduplication request
+ (struct uds_request) to the deduplication index. This does not
+ require the data_vio to get any locks because the index components
+ manage their own locking. The data_vio waits until it either gets a
+ response from the index or times out.
+
+ b. If the deduplication index returns advice, the data_vio attempts to
+ obtain a physical block lock on the indicated physical address, in
+ order to read the data and verify that it is the same as the
+ data_vio's data, and that it can accept more references. If the
+ physical address is already locked by another data_vio, the data at
+ that address may soon be overwritten so it is not safe to use the
+ address for deduplication.
+
+ c. If the data matches and the physical block can add references, the
+ agent and any other data_vios waiting on it will record this
+ physical block as their new physical address and proceed to step 9
+ to record their new mapping. If there are more data_vios in the hash
+ lock than there are references available, one of the remaining
+ data_vios becomes the new agent and continues to step 8d as if no
+ valid advice was returned.
+
+ d. If no usable duplicate block was found, the agent first checks that
+ it has an allocated physical block (from step 3) that it can write
+ to. If the agent does not have an allocation, some other data_vio in
+ the hash lock that does have an allocation takes over as agent. If
+ none of the data_vios have an allocated physical block, these writes
+ are out of space, so they proceed to step 13 for cleanup.
+
+ e. The agent attempts to compress its data. If the data does not
+ compress, the data_vio will continue to step 8h to write its data
+ directly.
+
+ If the compressed size is small enough, the agent will release the
+ implicit hash zone lock and go to the packer (struct packer) where
+ it will be placed in a bin (struct packer_bin) along with other
+ data_vios. All compression operations require the implicit lock on
+ the packer zone.
+
+ The packer can combine up to 14 compressed blocks in a single 4k
+ data block. Compression is only helpful if vdo can pack at least 2
+ data_vios into a single data block. This means that a data_vio may
+ wait in the packer for an arbitrarily long time for other data_vios
+ to fill out the compressed block. There is a mechanism for vdo to
+ evict waiting data_vios when continuing to wait would cause
+ problems. Circumstances causing an eviction include an application
+ flush, device shutdown, or a subsequent data_vio trying to overwrite
+ the same logical block address. A data_vio may also be evicted from
+ the packer if it cannot be paired with any other compressed block
+ before more compressible blocks need to use its bin. An evicted
+ data_vio will proceed to step 8h to write its data directly.
+
+ f. If the agent fills a packer bin, either because all 14 of its slots
+ are used or because it has no remaining space, it is written out
+ using the allocated physical block from one of its data_vios. Step
+ 8d has already ensured that an allocation is available.
+
+ g. Each data_vio sets the compressed block as its new physical address.
+ The data_vio obtains an implicit lock on the physical zone and
+ acquires the struct pbn_lock for the compressed block, which is
+ modified to be a shared lock. Then it releases the implicit physical
+ zone lock and proceeds to step 8i.
+
+ h. Any data_vio evicted from the packer will have an allocation from
+ step 3. It will write its data to that allocated physical block.
+
+ i. After the data is written, if the data_vio is the agent of a hash
+ lock, it will reacquire the implicit hash zone lock and share its
+ physical address with as many other data_vios in the hash lock as
+ possible. Each data_vio will then proceed to step 9 to record its
+ new mapping.
+
+ j. If the agent actually wrote new data (whether compressed or not),
+ the deduplication index is updated to reflect the location of the
+ new data. The agent then releases the implicit hash zone lock.
+
+9. The data_vio determines the previous mapping of the logical address.
+ There is a cache for block map leaf pages (the "block map cache"),
+ because there are usually too many block map leaf nodes to store
+ entirely in memory. If the desired leaf page is not in the cache, the
+ data_vio will reserve a slot in the cache and load the desired page
+ into it, possibly evicting an older cached page. The data_vio then
+ finds the current physical address for this logical address (the "old
+ physical mapping"), if any, and records it. This step requires a lock
+ on the block map cache structures, covered by the implicit logical zone
+ lock.
+
+10. The data_vio makes an entry in the recovery journal containing the
+ logical block address, the old physical mapping, and the new physical
+ mapping. Making this journal entry requires holding the implicit
+ recovery journal lock. The data_vio will wait in the journal until all
+ recovery blocks up to the one containing its entry have been written
+ and flushed to ensure the transaction is stable on storage.
+
+11. Once the recovery journal entry is stable, the data_vio makes two slab
+ journal entries: an increment entry for the new mapping, and a
+ decrement entry for the old mapping. These two operations each require
+ holding a lock on the affected physical slab, covered by its implicit
+ physical zone lock. For correctness during recovery, the slab journal
+ entries in any given slab journal must be in the same order as the
+ corresponding recovery journal entries. Therefore, if the two entries
+ are in different zones, they are made concurrently, and if they are in
+ the same zone, the increment is always made before the decrement in
+ order to avoid underflow. After each slab journal entry is made in
+ memory, the associated reference count is also updated in memory.
+
+12. Once both of the reference count updates are done, the data_vio
+ acquires the implicit logical zone lock and updates the
+ logical-to-physical mapping in the block map to point to the new
+ physical block. At this point the write operation is complete.
+
+13. If the data_vio has a hash lock, it acquires the implicit hash zone
+ lock and releases its hash lock to the pool.
+
+ The data_vio then acquires the implicit physical zone lock and releases
+ the struct pbn_lock it holds for its allocated block. If it had an
+ allocation that it did not use, it also sets the reference count for
+ that block back to zero to free it for use by subsequent data_vios.
+
+ The data_vio then acquires the implicit logical zone lock and releases
+ the logical block lock acquired in step 2.
+
+ The application bio is then acknowledged if it has not previously been
+ acknowledged, and the data_vio is returned to the pool.
+
+*Read Path*
+
+An application read bio follows a much simpler set of steps. It does steps
+1 and 2 in the write path to obtain a data_vio and lock its logical
+address. If there is already a write data_vio in progress for that logical
+address that is guaranteed to complete, the read data_vio will copy the
+data from the write data_vio and return it. Otherwise, it will look up the
+logical-to-physical mapping by traversing the block map tree as in step 3,
+and then read and possibly decompress the indicated data at the indicated
+physical block address. A read data_vio will not allocate block map tree
+nodes if they are missing. If the interior block map nodes do not exist
+yet, the logical block map address must still be unmapped and the read
+data_vio will return all zeroes. A read data_vio handles cleanup and
+acknowledgment as in step 13, although it only needs to release the logical
+lock and return itself to the pool.
+
+*Small Writes*
+
+All storage within vdo is managed as 4KB blocks, but it can accept writes
+as small as 512 bytes. Processing a write that is smaller than 4K requires
+a read-modify-write operation that reads the relevant 4K block, copies the
+new data over the appropriate sectors of the block, and then launches a
+write operation for the modified data block. The read and write stages of
+this operation are nearly identical to the normal read and write
+operations, and a single data_vio is used throughout this operation.
+
+*Recovery*
+
+When a vdo is restarted after a crash, it will attempt to recover from the
+recovery journal. During the pre-resume phase of the next start, the
+recovery journal is read. The increment portion of valid entries are played
+into the block map. Next, valid entries are played, in order as required,
+into the slab journals. Finally, each physical zone attempts to replay at
+least one slab journal to reconstruct the reference counts of one slab.
+Once each zone has some free space (or has determined that it has none),
+the vdo comes back online, while the remainder of the slab journals are
+used to reconstruct the rest of the reference counts in the background.
+
+*Read-only Rebuild*
+
+If a vdo encounters an unrecoverable error, it will enter read-only mode.
+This mode indicates that some previously acknowledged data may have been
+lost. The vdo may be instructed to rebuild as best it can in order to
+return to a writable state. However, this is never done automatically due
+to the possibility that data has been lost. During a read-only rebuild, the
+block map is recovered from the recovery journal as before. However, the
+reference counts are not rebuilt from the slab journals. Instead, the
+reference counts are zeroed, the entire block map is traversed, and the
+reference counts are updated from the block mappings. While this may lose
+some data, it ensures that the block map and reference counts are
+consistent with each other. This allows vdo to resume normal operation and
+accept further writes.

+
+The dm-vdo (virtual data optimizer) device mapper target provides
+block-level deduplication, compression, and thin provisioning. As a device
+mapper target, it can add these features to the storage stack, compatible
+with any file system. The vdo target does not protect against data
+corruption, relying instead on integrity protection of the storage below
+it. It is strongly recommended that lvm be used to manage vdo volumes. See
+lvmvdo(7).
+
+Userspace component
+===================
+
+Formatting a vdo volume requires the use of the 'vdoformat' tool, available
+at:
+
+https://github.com/dm-vdo/vdo/
+
+In most cases, a vdo target will recover from a crash automatically the
+next time it is started. In cases where it encountered an unrecoverable
+error (either during normal operation or crash recovery) the target will
+enter or come up in read-only mode. Because read-only mode is indicative of
+data-loss, a positive action must be taken to bring vdo out of read-only
+mode. The 'vdoforcerebuild' tool, available from the same repo, is used to
+prepare a read-only vdo to exit read-only mode. After running this tool,
+the vdo target will rebuild its metadata the next time it is
+started. Although some data may be lost, the rebuilt vdo's metadata will be
+internally consistent and the target will be writable again.
+
+The repo also contains additional userspace tools which can be used to
+inspect a vdo target's on-disk metadata. Fortunately, these tools are
+rarely needed except by dm-vdo developers.
+
+Metadata requirements
+=====================
+
+Each vdo volume reserves 3GB of space for metadata, or more depending on
+its configuration. It is helpful to check that the space saved by
+deduplication and compression is not cancelled out by the metadata
+requirements. An estimation of the space saved for a specific dataset can
+be computed with the vdo estimator tool, which is available at:
+
+https://github.com/dm-vdo/vdoestimator/

+ The size of the device holding the vdo volume, as a number
+ of 4096-byte blocks. Must match the current size of the vdo
+ volume.
+
+ minimum I/O size:
+ The minimum I/O size for this vdo volume to accept, in
+ bytes. Valid values are 512 or 4096. The recommended value
+ is 4096.
+
+ block map cache size:
+ The size of the block map cache, as a number of 4096-byte
+ blocks. The minimum and recommended value is 32768 blocks.
+ If the logical thread count is non-zero, the cache size
+ must be at least 4096 blocks per logical thread.
+
+ block map era length:
+ The speed with which the block map cache writes out
+ modified block map pages. A smaller era length is likely to
+ reduce the amount of time spent rebuilding, at the cost of
+ increased block map writes during normal operation. The
+ maximum and recommended value is 16380; the minimum value
+ is 1.
+
+Optional parameters:
+--------------------
+Some or all of these parameters may be specified as <key> <value> pairs.
+
+Thread related parameters:
+
+Different categories of work are assigned to separate thread groups, and
+the number of threads in each group can be configured separately.
+
+If <hash>, <logical>, and <physical> are all set to 0, the work handled by
+all three thread types will be handled by a single thread. If any of these
+values are non-zero, all of them must be non-zero.
+
+ ack:
+ The number of threads used to complete bios. Since
+ completing a bio calls an arbitrary completion function
+ outside the vdo volume, threads of this type allow the vdo
+ volume to continue processing requests even when bio
+ completion is slow. The default is 1.
+
+ bio:
+ The number of threads used to issue bios to the underlying
+ storage. Threads of this type allow the vdo volume to
+ continue processing requests even when bio submission is
+ slow. The default is 4.
+
+ bioRotationInterval:
+ The number of bios to enqueue on each bio thread before
+ switching to the next thread. The value must be greater
+ than 0 and not more than 1024; the default is 64.
+
+ cpu:
+ The number of threads used to do CPU-intensive work, such
+ as hashing and compression. The default is 1.
+
+ hash:
+ The number of threads used to manage data comparisons for
+ deduplication based on the hash value of data blocks. The
+ default is 0.
+
+ logical:
+ The number of threads used to manage caching and locking
+ based on the logical address of incoming bios. The default
+ is 0; the maximum is 60.
+
+ physical:
+ The number of threads used to manage administration of the
+ underlying storage device. At format time, a slab size for
+ the vdo is chosen; the vdo storage device must be large
+ enough to have at least 1 slab per physical thread. The
+ default is 0; the maximum is 16.
+
+Miscellaneous parameters:
+
+ maxDiscard:
+ The maximum size of discard bio accepted, in 4096-byte
+ blocks. I/O requests to a vdo volume are normally split
+ into 4096-byte blocks, and processed up to 2048 at a time.
+ However, discard requests to a vdo volume can be
+ automatically split to a larger size, up to <maxDiscard>
+ 4096-byte blocks in a single bio, and are limited to 1500
+ at a time. Increasing this value may provide better overall
+ performance, at the cost of increased latency for the
+ individual discard requests. The default and minimum is 1;
+ the maximum is UINT_MAX / 4096.
+
+ deduplication:
+ Whether deduplication is enabled. The default is 'on'; the
+ acceptable values are 'on' and 'off'.
+
+ compression:
+ Whether compression is enabled. The default is 'off'; the
+ acceptable values are 'on' and 'off'.
+
+Device modification
+-------------------
+
+A modified table may be loaded into a running, non-suspended vdo volume.
+The modifications will take effect when the device is next resumed. The
+modifiable parameters are <logical device size>, <physical device size>,
+<maxDiscard>, <compression>, and <deduplication>.
+
+If the logical device size or physical device size are changed, upon
+successful resume vdo will store the new values and require them on future
+startups. These two parameters may not be decreased. The logical device
+size may not exceed 4 PB. The physical device size must increase by at
+least 32832 4096-byte blocks if at all, and must not exceed the size of the
+underlying storage device. Additionally, when formatting the vdo device, a
+slab size is chosen: the physical device size may never increase above the
+size which provides 8192 slabs, and each increase must be large enough to
+add at least one new slab.
+
+Examples:
+
+Start a previously-formatted vdo volume with 1 GB logical space and 1 GB
+physical space, storing to /dev/dm-1 which has more than 1 GB of space.
+
+::
+
+ dmsetup create vdo0 --table \
+ "0 2097152 vdo V4 /dev/dm-1 262144 4096 32768 16380"
+
+Grow the logical size to 4 GB.
+
+::
+
+ dmsetup reload vdo0 --table \
+ "0 8388608 vdo V4 /dev/dm-1 262144 4096 32768 16380"
+ dmsetup resume vdo0
+
+Grow the physical size to 2 GB.
+
+::
+
+ dmsetup reload vdo0 --table \
+ "0 8388608 vdo V4 /dev/dm-1 524288 4096 32768 16380"
+ dmsetup resume vdo0
+
+Grow the physical size by 1 GB more and increase max discard sectors.
+
+::
+
+ dmsetup reload vdo0 --table \
+ "0 10485760 vdo V4 /dev/dm-1 786432 4096 32768 16380 maxDiscard 8"
+ dmsetup resume vdo0
+
+Stop the vdo volume.
+
+::
+
+ dmsetup remove vdo0
+
+Start the vdo volume again. Note that the logical and physical device sizes
+must still match, but other parameters can change.
+
+::
+
+ dmsetup create vdo1 --table \
+ "0 10485760 vdo V4 /dev/dm-1 786432 512 65550 5000 hash 1 logical 3 physical 2"
+
+Messages
+--------
+All vdo devices accept messages in the form:
+
+::
+
+ dmsetup message <target-name> 0 <message-name> <message-parameters>
+
+The messages are:
+
+ stats:
+ Outputs the current view of the vdo statistics. Mostly used
+ by the vdostats userspace program to interpret the output
+ buffer.
+
+ config:
+ Outputs useful vdo configuration information. Mostly used
+ by users who want to recreate a similar VDO volume and
+ want to know the creation configuration used.
+
+ dump:
+ Dumps many internal structures to the system log. This is
+ not always safe to run, so it should only be used to debug
+ a hung vdo. Optional parameters to specify structures to
+ dump are:
+
+ viopool: The pool of I/O requests incoming bios
+ pools: A synonym of 'viopool'
+ vdo: Most of the structures managing on-disk data
+ queues: Basic information about each vdo thread
+ threads: A synonym of 'queues'
+ default: Equivalent to 'queues vdo'
+ all: All of the above.
+
+ dump-on-shutdown:
+ Perform a default dump next time vdo shuts down.

+
+Memory Requirements
+===================
+
+A vdo target requires a fixed 38 MB of RAM along with the following amounts
+that scale with the target:
+
+- 1.15 MB of RAM for each 1 MB of configured block map cache size. The
+ block map cache requires a minimum of 150 MB.
+- 1.6 MB of RAM for each 1 TB of logical space.
+- 268 MB of RAM for each 1 TB of physical storage managed by the volume.
+
+The deduplication index requires additional memory which scales with the
+size of the deduplication window. For dense indexes, the index requires 1
+GB of RAM per 1 TB of window. For sparse indexes, the index requires 1 GB
+of RAM per 10 TB of window. The index configuration is set when the target
+is formatted and may not be modified.
+
+Module Parameters
+=================
+
+The vdo driver has a numeric parameter 'log_level' which controls the
+verbosity of logging from the driver. The default setting is 6
+(LOGLEVEL_INFO and more severe messages).
+
+Run-time Usage
+==============
+
+When using dm-vdo, it is important to be aware of the ways in which its
+behavior differs from other storage targets.
+
+- There is no guarantee that over-writes of existing blocks will succeed.
+ Because the underlying storage may be multiply referenced, over-writing
+ an existing block generally requires a vdo to have a free block
+ available.
+
+- When blocks are no longer in use, sending a discard request for those
+ blocks lets the vdo release references for those blocks. If the vdo is
+ thinly provisioned, discarding unused blocks is essential to prevent the
+ target from running out of space. However, due to the sharing of
+ duplicate blocks, no discard request for any given logical block is
+ guaranteed to reclaim space.
+
+- Assuming the underlying storage properly implements flush requests, vdo
+ is resilient against crashes, however, unflushed writes may or may not
+ persist after a crash.
+
+- Each write to a vdo target entails a significant amount of processing.
+ However, much of the work is paralellizable. Therefore, vdo targets
+ achieve better throughput at higher I/O depths, and can support up 2048
+ requests in parallel.
+
+Tuning
+======
+
+The vdo device has many options, and it can be difficult to make optimal
+choices without perfect knowledge of the workload. Additionally, most
+configuration options must be set when a vdo target is started, and cannot
+be changed without shutting it down completely; the configuration cannot be
+changed while the target is active. Ideally, tuning with simulated
+workloads should be performed before deploying vdo in production
+environments.
+
+The most important value to adjust is the block map cache size. In order to
+service a request for any logical address, a vdo must load the portion of
+the block map which holds the relevant mapping. These mappings are cached.
+Performance will suffer when the working set does not fit in the cache. By
+default, a vdo allocates 128 MB of metadata cache in RAM to support
+efficient access to 100 GB of logical space at a time. It should be scaled
+up proportionally for larger working sets.
+
+The logical and physical thread counts should also be adjusted. A logical
+thread controls a disjoint section of the block map, so additional logical
+threads increase parallelism and can increase throughput. Physical threads
+control a disjoint section of the data blocks, so additional physical
+threads can also increase throughput. However, excess threads can waste
+resources and increase contention.
+
+Bio submission threads control the parallelism involved in sending I/O to
+the underlying storage; fewer threads mean there is more opportunity to
+reorder I/O requests for performance benefit, but also that each I/O
+request has to wait longer before being submitted.
+
+Bio acknowledgment threads are used for finishing I/O requests. This is
+done on dedicated threads since the amount of work required to execute a
+bio's callback can not be controlled by the vdo itself. Usually one thread
+is sufficient but additional threads may be beneficial, particularly when
+bios have CPU-heavy callbacks.
+
+CPU threads are used for hashing and for compression; in workloads with
+compression enabled, more threads may result in higher throughput.
+
+Hash threads are used to sort active requests by hash and determine whether
+they should deduplicate; the most CPU intensive actions done by these
+threads are comparison of 4096-byte data blocks. In most cases, a single
+hash thread is sufficient.

+ This is useful for identifying a character device for the newly created
+ aggregator. If it's ``gpio-aggregator.0``,
+ ``/sys/devices/platform/gpio-aggregator.0/gpiochipX`` path tells you that the
+ GPIO device id is ``X``.
+
+You must create subdirectories for each virtual line you want to
+instantiate, named exactly as ``line0``, ``line1``, ..., ``lineY``, when
+you want to instantiate ``Y+1`` (Y >= 0) lines. Configure all lines before
+activating the device by setting ``live`` to 1.
+
+**Group:** ``/config/gpio-aggregator/<example-name>/<lineY>/``
+
+ This directory represents a GPIO line to include in the aggregator.
+
+**Attribute:** ``/config/gpio-aggregator/<example-name>/<lineY>/key``
+
+**Attribute:** ``/config/gpio-aggregator/<example-name>/<lineY>/offset``
+
+ The default values after creating the ``<lineY>`` directory are:
+
+ * ``key`` : <empty>
+ * ``offset`` : -1
+
+ ``key`` must always be explicitly configured, while ``offset`` depends.
+ Two configuration patterns exist for each ``<lineY>``:
+
+ (a). For lookup by GPIO line name:
+
+ * Set ``key`` to the line name.
+ * Ensure ``offset`` remains -1 (the default).
+
+ (b). For lookup by GPIO chip name and the line offset within the chip:
+
+ * Set ``key`` to the chip name.
+ * Set ``offset`` to the line offset (0 <= ``offset`` < 65535).
+
+**Attribute:** ``/config/gpio-aggregator/<example-name>/<lineY>/name``
+
+ The ``name`` attribute sets a custom name for lineY. If left unset, the
+ line will remain unnamed.
+
+Once the configuration is done, the ``'live'`` attribute must be set to 1
+in order to instantiate the aggregator device. It can be set back to 0 to
+destroy the virtual device. The module will synchronously wait for the new
+aggregator device to be successfully probed and if this doesn't happen, writing
+to ``'live'`` will result in an error. This is a different behaviour from the
+case when you create it using sysfs ``new_device`` interface.
+
+.. note::
+
+ For aggregators created via Sysfs, the configfs entries are
+ auto-generated and appear as ``/config/gpio-aggregator/_sysfs.<N>/``. You
+ cannot add or remove line directories with mkdir(2)/rmdir(2). To modify
+ lines, you must use the "delete_device" interface to tear down the
+ existing device and reconfigure it from scratch. However, you can still
+ toggle the aggregator with the ``live`` attribute and adjust the
+ ``key``, ``offset``, and ``name`` attributes for each line when ``live``
+ is set to 0 by hand (i.e. it's not waiting for deferred probe).
+
+Sample configuration commands
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: sh
+
+ # Create a directory for an aggregator device
+ $ mkdir /sys/kernel/config/gpio-aggregator/agg0
+
+ # Configure each line
+ $ mkdir /sys/kernel/config/gpio-aggregator/agg0/line0

+Virtual GPIO Consumer
+=====================
+
+The virtual GPIO Consumer module allows users to instantiate virtual devices
+that request GPIOs and then control their behavior over debugfs. Virtual
+consumer devices can be instantiated from device-tree or over configfs.
+
+A virtual consumer uses the driver-facing GPIO APIs and allows to cover it with
+automated tests driven by user-space. The GPIOs are requested using
+``gpiod_get_array()`` and so we support multiple GPIOs per connector ID.
+
+Creating GPIO consumers
+-----------------------
+
+The gpio-consumer module registers a configfs subsystem called
+``'gpio-virtuser'``. For details of the configfs filesystem, please refer to
+the configfs documentation.
+
+The user can create a hierarchy of configfs groups and items as well as modify
+values of exposed attributes. Once the consumer is instantiated, this hierarchy
+will be translated to appropriate device properties. The general structure is:
+
+**Group:** ``/config/gpio-virtuser``
+
+This is the top directory of the gpio-consumer configfs tree.
+
+**Group:** ``/config/gpio-consumer/example-name``
+
+**Attribute:** ``/config/gpio-consumer/example-name/live``
+
+**Attribute:** ``/config/gpio-consumer/example-name/dev_name``
+
+This is a directory representing a GPIO consumer device.
+
+The read-only ``dev_name`` attribute exposes the name of the device as it will
+appear in the system on the platform bus. This is useful for locating the
+associated debugfs directory under
+``/sys/kernel/debug/gpio-virtuser/$dev_name``.
+
+The ``'live'`` attribute allows to trigger the actual creation of the device
+once it's fully configured. The accepted values are: ``'1'`` to enable the
+virtual device and ``'0'`` to disable and tear it down.
+
+Creating GPIO lookup tables
+---------------------------
+
+Users can create a number of configfs groups under the device group:
+
+**Group:** ``/config/gpio-consumer/example-name/con_id``
+
+The ``'con_id'`` directory represents a single GPIO lookup and its value maps
+to the ``'con_id'`` argument of the ``gpiod_get()`` function. For example:
+``con_id`` == ``'reset'`` maps to the ``reset-gpios`` device property.
+
+Users can assign a number of GPIOs to each lookup. Each GPIO is a sub-directory
+with a user-defined name under the ``'con_id'`` group.
+
+**Attribute:** ``/config/gpio-consumer/example-name/con_id/0/key``
+
+**Attribute:** ``/config/gpio-consumer/example-name/con_id/0/offset``
+
+**Attribute:** ``/config/gpio-consumer/example-name/con_id/0/drive``
+
+**Attribute:** ``/config/gpio-consumer/example-name/con_id/0/pull``
+
+**Attribute:** ``/config/gpio-consumer/example-name/con_id/0/active_low``
+
+**Attribute:** ``/config/gpio-consumer/example-name/con_id/0/transitory``
+
+This is a group describing a single GPIO in the ``con_id-gpios`` property.
+
+For virtual consumers created using configfs we use machine lookup tables so
+this group can be considered as a mapping between the filesystem and the fields
+of a single entry in ``'struct gpiod_lookup'``.
+
+The ``'key'`` attribute represents either the name of the chip this GPIO
+belongs to or the GPIO line name. This depends on the value of the ``'offset'``
+attribute: if its value is >= 0, then ``'key'`` represents the label of the
+chip to lookup while ``'offset'`` represents the offset of the line in that
+chip. If ``'offset'`` is < 0, then ``'key'`` represents the name of the line.
+
+The remaining attributes map to the ``'flags'`` field of the GPIO lookup
+struct. The first two take string values as arguments:
+
+**``'drive'``:** ``'push-pull'``, ``'open-drain'``, ``'open-source'``
+**``'pull'``:** ``'pull-up'``, ``'pull-down'``, ``'pull-disabled'``, ``'as-is'``
+
+``'active_low'`` and ``'transitory'`` are boolean attributes.
+
+Activating GPIO consumers
+-------------------------
+
+Once the configuration is complete, the ``'live'`` attribute must be set to 1 in
+order to instantiate the consumer. It can be set back to 0 to destroy the
+virtual device. The module will synchronously wait for the new simulated device
+to be successfully probed and if this doesn't happen, writing to ``'live'`` will
+result in an error.
+
+Device-tree
+-----------
+
+Virtual GPIO consumers can also be defined in device-tree. The compatible string
+must be: ``"gpio-virtuser"`` with at least one property following the
+standardized GPIO pattern.
+
+An example device-tree code defining a virtual GPIO consumer:
+
+.. code-block :: none
+
+ gpio-virt-consumer {
+ compatible = "gpio-virtuser";
+
+ foo-gpios = <&gpio0 5 GPIO_ACTIVE_LOW>, <&gpio1 2 0>;
+ bar-gpios = <&gpio0 6 0>;
+ };
+
+Controlling virtual GPIO consumers
+----------------------------------
+
+Once active, the device will export debugfs attributes for controlling GPIO
+arrays as well as each requested GPIO line separately. Let's consider the
+following device property: ``foo-gpios = <&gpio0 0 0>, <&gpio0 4 0>;``.
+
+The following debugfs attribute groups will be created:
+
+**Group:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo/``
+
+This is the group that will contain the attributes for the entire GPIO array.
+
+**Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo/values``
+
+**Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo/values_atomic``
+
+Both attributes allow to read and set arrays of GPIO values. User must pass
+exactly the number of values that the array contains in the form of a string
+containing zeroes and ones representing inactive and active GPIO states
+respectively. In this example: ``echo 11 > values``.
+
+The ``values_atomic`` attribute works the same as ``values`` but the kernel
+will execute the GPIO driver callbacks in interrupt context.
+
+**Group:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo:$index/``
+
+This is a group that represents a single GPIO with ``$index`` being its offset
+in the array.
+
+**Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo:$index/consumer``
+
+Allows to set and read the consumer label of the GPIO line.
+
+**Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo:$index/debounce``
+
+Allows to set and read the debounce period of the GPIO line.
+
+**Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo:$index/direction``
+
+**Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo:$index/direction_atomic``
+
+These two attributes allow to set the direction of the GPIO line. They accept
+"input" and "output" as values. The atomic variant executes the driver callback
+in interrupt context.
+
+**Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo:$index/interrupts``
+
+If the line is requested in input mode, writing ``1`` to this attribute will
+make the module listen for edge interrupts on the GPIO. Writing ``0`` disables
+the monitoring. Reading this attribute returns the current number of registered
+interrupts (both edges).
+
+**Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo:$index/value``
+
+**Attribute:** ``/sys/kernel/debug/gpio-virtuser/$dev_name/gpiod:foo:$index/value_atomic``
+
+Both attributes allow to read and set values of individual requested GPIO lines.
+They accept the following values: ``1`` and ``0``.

-Notes on the change from 16-bit UIDs to 32-bit UIDs
-===================================================
-
-:Author: Chris Wing <wingc@umich.edu>
-:Last updated: January 11, 2000
-
-- kernel code MUST take into account __kernel_uid_t and __kernel_uid32_t
- when communicating between user and kernel space in an ioctl or data
- structure.
-
-- kernel code should use uid_t and gid_t in kernel-private structures and
- code.
-
-What's left to be done for 32-bit UIDs on all Linux architectures:
-
-- Disk quotas have an interesting limitation that is not related to the
- maximum UID/GID. They are limited by the maximum file size on the
- underlying filesystem, because quota records are written at offsets
- corresponding to the UID in question.
- Further investigation is needed to see if the quota system can cope
- properly with huge UIDs. If it can deal with 64-bit file offsets on all
- architectures, this should not be a problem.
-
-- Decide whether or not to keep backwards compatibility with the system
- accounting file, or if we should break it as the comments suggest
- (currently, the old 16-bit UID and GID are still written to disk, and
- part of the former pad space is used to store separate 32-bit UID and
- GID)
-
-- Need to validate that OS emulation calls the 16-bit UID
- compatibility syscalls, if the OS being emulated used 16-bit UIDs, or
- uses the 32-bit UID system calls properly otherwise.
-
- This affects at least:
-
- - iBCS on Intel
-
- - sparc32 emulation on sparc64
- (need to support whatever new 32-bit UID system calls are added to
- sparc32)
-
-- Validate that all filesystems behave properly.
-
- At present, 32-bit UIDs _should_ work for:
-
- - ext2
- - ufs
- - isofs
- - nfs
- - coda
- - udf
-
- Ioctl() fixups have been made for:
-
- - ncpfs
- - smbfs
-
- Filesystems with simple fixups to prevent 16-bit UID wraparound:
-
- - minix
- - sysv
- - qnx4
-
- Other filesystems have not been checked yet.
-
-- The ncpfs and smpfs filesystems cannot presently use 32-bit UIDs in
- all ioctl()s. Some new ioctl()s have been added with 32-bit UIDs, but
- more are needed. (as well as new user<->kernel data structures)
-
-- The ELF core dump format only supports 16-bit UIDs on arm, i386, m68k,
- sh, and sparc32. Fixing this is probably not that important, but would
- require adding a new ELF section.
-
-- The ioctl()s used to control the in-kernel NFS server only support
- 16-bit UIDs on arm, i386, m68k, sh, and sparc32.
-
-- make sure that the UID mapping feature of AX25 networking works properly
- (it should be safe because it's always used a 32-bit integer to
- communicate between user and kernel)

+Attack Vector Controls
+======================
+
+Attack vector controls provide a simple method to configure only the mitigations
+for CPU vulnerabilities which are relevant given the intended use of a system.
+Administrators are encouraged to consider which attack vectors are relevant and
+disable all others in order to recoup system performance.
+
+When new relevant CPU vulnerabilities are found, they will be added to these
+attack vector controls so administrators will likely not need to reconfigure
+their command line parameters as mitigations will continue to be correctly
+applied based on the chosen attack vector controls.
+
+Attack Vectors
+--------------
+
+There are 5 sets of attack-vector mitigations currently supported by the kernel:
+
+#. :ref:`user_kernel`
+#. :ref:`user_user`
+#. :ref:`guest_host`
+#. :ref:`guest_guest`
+#. :ref:`smt`
+
+To control the enabled attack vectors, see :ref:`cmdline`.
+
+.. _user_kernel:
+
+User-to-Kernel
+^^^^^^^^^^^^^^
+
+The user-to-kernel attack vector involves a malicious userspace program
+attempting to leak kernel data into userspace by exploiting a CPU vulnerability.
+The kernel data involved might be limited to certain kernel memory, or include
+all memory in the system, depending on the vulnerability exploited.
+
+If no untrusted userspace applications are being run, such as with single-user
+systems, consider disabling user-to-kernel mitigations.
+
+Note that the CPU vulnerabilities mitigated by Linux have generally not been
+shown to be exploitable from browser-based sandboxes. User-to-kernel
+mitigations are therefore mostly relevant if unknown userspace applications may
+be run by untrusted users.
+
+*user-to-kernel mitigations are enabled by default*
+
+.. _user_user:
+
+User-to-User
+^^^^^^^^^^^^
+
+The user-to-user attack vector involves a malicious userspace program attempting
+to influence the behavior of another unsuspecting userspace program in order to
+exfiltrate data. The vulnerability of a userspace program is based on the
+program itself and the interfaces it provides.
+
+If no untrusted userspace applications are being run, consider disabling
+user-to-user mitigations.
+
+Note that because the Linux kernel contains a mapping of all physical memory,
+preventing a malicious userspace program from leaking data from another
+userspace program requires mitigating user-to-kernel attacks as well for
+complete protection.
+
+*user-to-user mitigations are enabled by default*
+
+.. _guest_host:
+
+Guest-to-Host
+^^^^^^^^^^^^^
+
+The guest-to-host attack vector involves a malicious VM attempting to leak
+hypervisor data into the VM. The data involved may be limited, or may
+potentially include all memory in the system, depending on the vulnerability
+exploited.
+
+If no untrusted VMs are being run, consider disabling guest-to-host mitigations.
+
+*guest-to-host mitigations are enabled by default if KVM support is present*
+
+.. _guest_guest:
+
+Guest-to-Guest
+^^^^^^^^^^^^^^
+
+The guest-to-guest attack vector involves a malicious VM attempting to influence
+the behavior of another unsuspecting VM in order to exfiltrate data. The
+vulnerability of a VM is based on the code inside the VM itself and the
+interfaces it provides.
+
+If no untrusted VMs, or only a single VM is being run, consider disabling
+guest-to-guest mitigations.
+
+Similar to the user-to-user attack vector, preventing a malicious VM from
+leaking data from another VM requires mitigating guest-to-host attacks as well
+due to the Linux kernel phys map.
+
+*guest-to-guest mitigations are enabled by default if KVM support is present*
+
+.. _smt:
+
+Cross-Thread
+^^^^^^^^^^^^
+
+The cross-thread attack vector involves a malicious userspace program or
+malicious VM either observing or attempting to influence the behavior of code
+running on the SMT sibling thread in order to exfiltrate data.
+
+Many cross-thread attacks can only be mitigated if SMT is disabled, which will
+result in reduced CPU core count and reduced performance.
+
+If cross-thread mitigations are fully enabled ('auto,nosmt'), all mitigations
+for cross-thread attacks will be enabled. SMT may be disabled depending on
+which vulnerabilities are present in the CPU.
+
+If cross-thread mitigations are partially enabled ('auto'), mitigations for
+cross-thread attacks will be enabled but SMT will not be disabled.
+
+If cross-thread mitigations are disabled, no mitigations for cross-thread
+attacks will be enabled.
+
+Cross-thread mitigation may not be required if core-scheduling or similar
+techniques are used to prevent untrusted workloads from running on SMT siblings.
+
+*cross-thread mitigations default to partially enabled*
+
+.. _cmdline:
+
+Command Line Controls
+---------------------
+
+Attack vectors are controlled through the mitigations= command line option. The
+value provided begins with a global option and then may optionally include one
+or more options to disable various attack vectors.
+
+Format:
+ | ``mitigations=[global]``
+ | ``mitigations=[global],[attack vectors]``
+
+Global options:
+
+============ =============================================================
+Option Description
+============ =============================================================
+'off' All attack vectors disabled.
+'auto' All attack vectors enabled, partial cross-thread mitigations.
+'auto,nosmt' All attack vectors enabled, full cross-thread mitigations.
+============ =============================================================
+
+Attack vector options:
+
+================= =======================================
+Option Description
+================= =======================================
+'no_user_kernel' Disables user-to-kernel mitigations.
+'no_user_user' Disables user-to-user mitigations.
+'no_guest_host' Disables guest-to-host mitigations.
+'no_guest_guest' Disables guest-to-guest mitigations
+'no_cross_thread' Disables all cross-thread mitigations.
+================= =======================================
+
+Multiple attack vector options may be specified in a comma-separated list. If
+the global option is not specified, it defaults to 'auto'. The global option
+'off' is equivalent to disabling all attack vectors.
+
+Examples:
+ | ``mitigations=auto,no_user_kernel``
+
+ Enable all attack vectors except user-to-kernel. Partial cross-thread
+ mitigations.
+
+ | ``mitigations=auto,nosmt,no_guest_host,no_guest_guest``
+
+ Enable all attack vectors and cross-thread mitigations except for
+ guest-to-host and guest-to-guest mitigations.
+
+ | ``mitigations=,no_cross_thread``
+
+ Enable all attack vectors but not cross-thread mitigations.
+
+Interactions with command-line options
+--------------------------------------
+
+Vulnerability-specific controls (e.g. "retbleed=off") take precedence over all
+attack vector controls. Mitigations for individual vulnerabilities may be
+turned on or off via their command-line options regardless of the attack vector
+controls.
+
+Summary of attack-vector mitigations
+------------------------------------
+
+When a vulnerability is mitigated due to an attack-vector control, the default
+mitigation option for that particular vulnerability is used. To use a different
+mitigation, please use the vulnerability-specific command line option.
+
+The table below summarizes which vulnerabilities are mitigated when different
+attack vectors are enabled and assuming the CPU is vulnerable.

+GDS - Gather Data Sampling
+==========================
+
+Gather Data Sampling is a hardware vulnerability which allows unprivileged
+speculative access to data which was previously stored in vector registers.
+
+Problem
+-------
+When a gather instruction performs loads from memory, different data elements
+are merged into the destination vector register. However, when a gather
+instruction that is transiently executed encounters a fault, stale data from
+architectural or internal vector registers may get transiently forwarded to the
+destination vector register instead. This will allow a malicious attacker to
+infer stale data using typical side channel techniques like cache timing
+attacks. GDS is a purely sampling-based attack.
+
+The attacker uses gather instructions to infer the stale vector register data.
+The victim does not need to do anything special other than use the vector
+registers. The victim does not need to use gather instructions to be
+vulnerable.
+
+Because the buffers are shared between Hyper-Threads cross Hyper-Thread attacks
+are possible.
+
+Attack scenarios
+----------------
+Without mitigation, GDS can infer stale data across virtually all
+permission boundaries:
+
+ Non-enclaves can infer SGX enclave data
+ Userspace can infer kernel data
+ Guests can infer data from hosts
+ Guest can infer guest from other guests
+ Users can infer data from other users
+
+Because of this, it is important to ensure that the mitigation stays enabled in
+lower-privilege contexts like guests and when running outside SGX enclaves.
+
+The hardware enforces the mitigation for SGX. Likewise, VMMs should ensure
+that guests are not allowed to disable the GDS mitigation. If a host erred and
+allowed this, a guest could theoretically disable GDS mitigation, mount an
+attack, and re-enable it.
+
+Mitigation mechanism
+--------------------
+This issue is mitigated in microcode. The microcode defines the following new
+bits:
+
+ ================================ === ============================
+ IA32_ARCH_CAPABILITIES[GDS_CTRL] R/O Enumerates GDS vulnerability
+ and mitigation support.
+ IA32_ARCH_CAPABILITIES[GDS_NO] R/O Processor is not vulnerable.
+ IA32_MCU_OPT_CTRL[GDS_MITG_DIS] R/W Disables the mitigation
+ 0 by default.
+ IA32_MCU_OPT_CTRL[GDS_MITG_LOCK] R/W Locks GDS_MITG_DIS=0. Writes
+ to GDS_MITG_DIS are ignored
+ Can't be cleared once set.
+ ================================ === ============================
+
+GDS can also be mitigated on systems that don't have updated microcode by
+disabling AVX. This can be done by setting gather_data_sampling="force" or
+"clearcpuid=avx" on the kernel command-line.
+
+If used, these options will disable AVX use by turning off XSAVE YMM support.
+However, the processor will still enumerate AVX support. Userspace that
+does not follow proper AVX enumeration to check both AVX *and* XSAVE YMM
+support will break.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The mitigation can be disabled by setting "gather_data_sampling=off" or
+"mitigations=off" on the kernel command line. Not specifying either will default
+to the mitigation being enabled. Specifying "gather_data_sampling=force" will
+use the microcode mitigation when available or disable AVX on affected systems
+where the microcode hasn't been updated to include the mitigation.
+
+GDS System Information
+------------------------
+The kernel provides vulnerability status information through sysfs. For
+GDS this can be accessed by the following sysfs file:
+
+/sys/devices/system/cpu/vulnerabilities/gather_data_sampling
+
+The possible values contained in this file are:
+
+ ============================== =============================================
+ Not affected Processor not vulnerable.
+ Vulnerable Processor vulnerable and mitigation disabled.
+ Vulnerable: No microcode Processor vulnerable and microcode is missing
+ mitigation.
+ Mitigation: AVX disabled,
+ no microcode Processor is vulnerable and microcode is missing
+ mitigation. AVX disabled as mitigation.
+ Mitigation: Microcode Processor is vulnerable and mitigation is in
+ effect.
+ Mitigation: Microcode (locked) Processor is vulnerable and mitigation is in
+ effect and cannot be disabled.
+ Unknown: Dependent on
+ hypervisor status Running on a virtual guest processor that is
+ affected but with no way to know if host
+ processor is mitigated or vulnerable.
+ ============================== =============================================
+
+GDS Default mitigation
+----------------------
+The updated microcode will enable the mitigation by default. The kernel's
+default action is to leave the mitigation enabled.

+Indirect Target Selection (ITS)
+===============================
+
+ITS is a vulnerability in some Intel CPUs that support Enhanced IBRS and were
+released before Alder Lake. ITS may allow an attacker to control the prediction
+of indirect branches and RETs located in the lower half of a cacheline.
+
+ITS is assigned CVE-2024-28956 with a CVSS score of 4.7 (Medium).
+
+Scope of Impact
+---------------
+- **eIBRS Guest/Host Isolation**: Indirect branches in KVM/kernel may still be
+ predicted with unintended target corresponding to a branch in the guest.
+
+- **Intra-Mode BTI**: In-kernel training such as through cBPF or other native
+ gadgets.
+
+- **Indirect Branch Prediction Barrier (IBPB)**: After an IBPB, indirect
+ branches may still be predicted with targets corresponding to direct branches
+ executed prior to the IBPB. This is fixed by the IPU 2025.1 microcode, which
+ should be available via distro updates. Alternatively microcode can be
+ obtained from Intel's github repository [#f1]_.
+

+- IBPB isolation is affected on all ITS affected CPUs, and need a microcode
+ update for mitigation.
+- None of the affected CPUs enumerate BHI_CTRL which was introduced in Golden
+ Cove (Alder Lake and Sapphire Rapids). This can help guests to determine the
+ host's affected status.
+- Intel Atom CPUs are not affected by ITS.
+
+Mitigation
+----------
+As only the indirect branches and RETs that have their last byte of instruction
+in the lower half of the cacheline are vulnerable to ITS, the basic idea behind
+the mitigation is to not allow indirect branches in the lower half.
+
+This is achieved by relying on existing retpoline support in the kernel, and in
+compilers. ITS-vulnerable retpoline sites are runtime patched to point to newly
+added ITS-safe thunks. These safe thunks consists of indirect branch in the
+second half of the cacheline. Not all retpoline sites are patched to thunks, if
+a retpoline site is evaluated to be ITS-safe, it is replaced with an inline
+indirect branch.
+
+Dynamic thunks
+~~~~~~~~~~~~~~
+From a dynamically allocated pool of safe-thunks, each vulnerable site is
+replaced with a new thunk, such that they get a unique address. This could
+improve the branch prediction accuracy. Also, it is a defense-in-depth measure
+against aliasing.
+
+Note, for simplicity, indirect branches in eBPF programs are always replaced
+with a jump to a static thunk in __x86_indirect_its_thunk_array. If required,
+in future this can be changed to use dynamic thunks.
+
+All vulnerable RETs are replaced with a static thunk, they do not use dynamic
+thunks. This is because RETs get their prediction from RSB mostly that does not
+depend on source address. RETs that underflow RSB may benefit from dynamic
+thunks. But, RETs significantly outnumber indirect branches, and any benefit
+from a unique source address could be outweighed by the increased icache
+footprint and iTLB pressure.
+
+Retpoline
+~~~~~~~~~
+Retpoline sequence also mitigates ITS-unsafe indirect branches. For this
+reason, when retpoline is enabled, ITS mitigation only relocates the RETs to
+safe thunks. Unless user requested the RSB-stuffing mitigation.
+
+RSB Stuffing
+~~~~~~~~~~~~
+RSB-stuffing via Call Depth Tracking is a mitigation for Retbleed RSB-underflow
+attacks. And it also mitigates RETs that are vulnerable to ITS.
+
+Mitigation in guests
+^^^^^^^^^^^^^^^^^^^^
+All guests deploy ITS mitigation by default, irrespective of eIBRS enumeration
+and Family/Model of the guest. This is because eIBRS feature could be hidden
+from a guest. One exception to this is when a guest enumerates BHI_DIS_S, which
+indicates that the guest is running on an unaffected host.
+
+To prevent guests from unnecessarily deploying the mitigation on unaffected
+platforms, Intel has defined ITS_NO bit(62) in MSR IA32_ARCH_CAPABILITIES. When
+a guest sees this bit set, it should not enumerate the ITS bug. Note, this bit
+is not set by any hardware, but is **intended for VMMs to synthesize** it for
+guests as per the host's affected status.
+
+Mitigation options
+^^^^^^^^^^^^^^^^^^
+The ITS mitigation can be controlled using the "indirect_target_selection"
+kernel parameter. The available options are:
+
+ ======== ===================================================================
+ on (default) Deploy the "Aligned branch/return thunks" mitigation.
+ If spectre_v2 mitigation enables retpoline, aligned-thunks are only
+ deployed for the affected RET instructions. Retpoline mitigates
+ indirect branches.
+
+ off Disable ITS mitigation.
+
+ vmexit Equivalent to "=on" if the CPU is affected by guest/host isolation
+ part of ITS. Otherwise, mitigation is not deployed. This option is
+ useful when host userspace is not in the threat model, and only
+ attacks from guest to host are considered.
+
+ stuff Deploy RSB-fill mitigation when retpoline is also deployed.
+ Otherwise, deploy the default mitigation. When retpoline mitigation
+ is enabled, RSB-stuffing via Call-Depth-Tracking also mitigates
+ ITS.
+
+ force Force the ITS bug and deploy the default mitigation.
+ ======== ===================================================================
+
+Sysfs reporting
+---------------
+
+The sysfs file showing ITS mitigation status is:

+Register File Data Sampling (RFDS)
+==================================
+
+Register File Data Sampling (RFDS) is a microarchitectural vulnerability that
+only affects Intel Atom parts(also branded as E-cores). RFDS may allow
+a malicious actor to infer data values previously used in floating point
+registers, vector registers, or integer registers. RFDS does not provide the
+ability to choose which data is inferred. CVE-2023-28746 is assigned to RFDS.

+Mitigation
+==========
+Intel released a microcode update that enables software to clear sensitive
+information using the VERW instruction. Like MDS, RFDS deploys the same
+mitigation strategy to force the CPU to clear the affected buffers before an
+attacker can extract the secrets. This is achieved by using the otherwise
+unused and obsolete VERW instruction in combination with a microcode update.
+The microcode clears the affected CPU buffers when the VERW instruction is
+executed.
+
+Mitigation points
+-----------------
+VERW is executed by the kernel before returning to user space, and by KVM
+before VMentry. None of the affected cores support SMT, so VERW is not required
+at C-state transitions.
+
+New bits in IA32_ARCH_CAPABILITIES
+----------------------------------
+Newer processors and microcode update on existing affected processors added new
+bits to IA32_ARCH_CAPABILITIES MSR. These bits can be used to enumerate
+vulnerability and mitigation capability:
+
+- Bit 27 - RFDS_NO - When set, processor is not affected by RFDS.
+- Bit 28 - RFDS_CLEAR - When set, processor is affected by RFDS, and has the
+ microcode that clears the affected buffers on VERW execution.
+
+Mitigation control on the kernel command line
+---------------------------------------------
+The kernel command line allows to control RFDS mitigation at boot time with the
+parameter "reg_file_data_sampling=". The valid arguments are:
+
+ ========== =================================================================
+ on If the CPU is vulnerable, enable mitigation; CPU buffer clearing

+RSB-related mitigations

+
+.. warning::
+ Please keep this document up-to-date, otherwise you will be
+ volunteered to update it and convert it to a very long comment in
+ bugs.c!
+
+Since 2018 there have been many Spectre CVEs related to the Return Stack
+Buffer (RSB) (sometimes referred to as the Return Address Stack (RAS) or
+Return Address Predictor (RAP) on AMD).
+
+Information about these CVEs and how to mitigate them is scattered
+amongst a myriad of microarchitecture-specific documents.
+
+This document attempts to consolidate all the relevant information in
+once place and clarify the reasoning behind the current RSB-related
+mitigations. It's meant to be as concise as possible, focused only on
+the current kernel mitigations: what are the RSB-related attack vectors
+and how are they currently being mitigated?
+
+It's *not* meant to describe how the RSB mechanism operates or how the
+exploits work. More details about those can be found in the references
+below.
+
+Rather, this is basically a glorified comment, but too long to actually
+be one. So when the next CVE comes along, a kernel developer can
+quickly refer to this as a refresher to see what we're actually doing
+and why.
+
+At a high level, there are two classes of RSB attacks: RSB poisoning
+(Intel and AMD) and RSB underflow (Intel only). They must each be
+considered individually for each attack vector (and microarchitecture
+where applicable).
+
+----
+
+RSB poisoning (Intel and AMD)
+=============================
+
+SpectreRSB
+~~~~~~~~~~
+
+RSB poisoning is a technique used by SpectreRSB [#spectre-rsb]_ where
+an attacker poisons an RSB entry to cause a victim's return instruction
+to speculate to an attacker-controlled address. This can happen when
+there are unbalanced CALLs/RETs after a context switch or VMEXIT.
+
+* All attack vectors can potentially be mitigated by flushing out any
+ poisoned RSB entries using an RSB filling sequence
+ [#intel-rsb-filling]_ [#amd-rsb-filling]_ when transitioning between
+ untrusted and trusted domains. But this has a performance impact and
+ should be avoided whenever possible.
+
+ .. DANGER::
+ **FIXME**: Currently we're flushing 32 entries. However, some CPU
+ models have more than 32 entries. The loop count needs to be
+ increased for those. More detailed information is needed about RSB
+ sizes.
+
+* On context switch, the user->user mitigation requires ensuring the
+ RSB gets filled or cleared whenever IBPB gets written [#cond-ibpb]_
+ during a context switch:
+
+ * AMD:
+ On Zen 4+, IBPB (or SBPB [#amd-sbpb]_ if used) clears the RSB.
+ This is indicated by IBPB_RET in CPUID [#amd-ibpb-rsb]_.
+
+ On Zen < 4, the RSB filling sequence [#amd-rsb-filling]_ must be
+ always be done in addition to IBPB [#amd-ibpb-no-rsb]_. This is
+ indicated by X86_BUG_IBPB_NO_RET.
+
+ * Intel:
+ IBPB always clears the RSB:
+
+ "Software that executed before the IBPB command cannot control
+ the predicted targets of indirect branches executed after the
+ command on the same logical processor. The term indirect branch
+ in this context includes near return instructions, so these
+ predicted targets may come from the RSB." [#intel-ibpb-rsb]_
+
+* On context switch, user->kernel attacks are prevented by SMEP. User
+ space can only insert user space addresses into the RSB. Even
+ non-canonical addresses can't be inserted due to the page gap at the
+ end of the user canonical address space reserved by TASK_SIZE_MAX.
+ A SMEP #PF at instruction fetch prevents the kernel from speculatively
+ executing user space.
+
+ * AMD:
+ "Finally, branches that are predicted as 'ret' instructions get
+ their predicted targets from the Return Address Predictor (RAP).
+ AMD recommends software use a RAP stuffing sequence (mitigation
+ V2-3 in [2]) and/or Supervisor Mode Execution Protection (SMEP)
+ to ensure that the addresses in the RAP are safe for
+ speculation. Collectively, we refer to these mitigations as "RAP
+ Protection"." [#amd-smep-rsb]_
+
+ * Intel:
+ "On processors with enhanced IBRS, an RSB overwrite sequence may
+ not suffice to prevent the predicted target of a near return
+ from using an RSB entry created in a less privileged predictor
+ mode. Software can prevent this by enabling SMEP (for
+ transitions from user mode to supervisor mode) and by having
+ IA32_SPEC_CTRL.IBRS set during VM exits." [#intel-smep-rsb]_
+
+* On VMEXIT, guest->host attacks are mitigated by eIBRS (and PBRSB
+ mitigation if needed):
+
+ * AMD:
+ "When Automatic IBRS is enabled, the internal return address
+ stack used for return address predictions is cleared on VMEXIT."
+ [#amd-eibrs-vmexit]_
+
+ * Intel:
+ "On processors with enhanced IBRS, an RSB overwrite sequence may
+ not suffice to prevent the predicted target of a near return
+ from using an RSB entry created in a less privileged predictor
+ mode. Software can prevent this by enabling SMEP (for
+ transitions from user mode to supervisor mode) and by having
+ IA32_SPEC_CTRL.IBRS set during VM exits. Processors with
+ enhanced IBRS still support the usage model where IBRS is set
+ only in the OS/VMM for OSes that enable SMEP. To do this, such
+ processors will ensure that guest behavior cannot control the
+ RSB after a VM exit once IBRS is set, even if IBRS was not set
+ at the time of the VM exit." [#intel-eibrs-vmexit]_
+
+ Note that some Intel CPUs are susceptible to Post-barrier Return
+ Stack Buffer Predictions (PBRSB) [#intel-pbrsb]_, where the last
+ CALL from the guest can be used to predict the first unbalanced RET.
+ In this case the PBRSB mitigation is needed in addition to eIBRS.
+
+AMD RETBleed / SRSO / Branch Type Confusion
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On AMD, poisoned RSB entries can also be created by the AMD RETBleed
+variant [#retbleed-paper]_ [#amd-btc]_ or by Speculative Return Stack
+Overflow [#amd-srso]_ (Inception [#inception-paper]_). The kernel
+protects itself by replacing every RET in the kernel with a branch to a
+single safe RET.
+
+----
+
+RSB underflow (Intel only)
+==========================
+
+RSB Alternate (RSBA) ("Intel Retbleed")
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Some Intel Skylake-generation CPUs are susceptible to the Intel variant
+of RETBleed [#retbleed-paper]_ (Return Stack Buffer Underflow
+[#intel-rsbu]_). If a RET is executed when the RSB buffer is empty due
+to mismatched CALLs/RETs or returning from a deep call stack, the branch
+predictor can fall back to using the Branch Target Buffer (BTB). If a
+user forces a BTB collision then the RET can speculatively branch to a
+user-controlled address.
+
+* Note that RSB filling doesn't fully mitigate this issue. If there
+ are enough unbalanced RETs, the RSB may still underflow and fall back
+ to using a poisoned BTB entry.
+
+* On context switch, user->user underflow attacks are mitigated by the
+ conditional IBPB [#cond-ibpb]_ on context switch which effectively
+ clears the BTB:
+
+ * "The indirect branch predictor barrier (IBPB) is an indirect branch
+ control mechanism that establishes a barrier, preventing software
+ that executed before the barrier from controlling the predicted
+ targets of indirect branches executed after the barrier on the same
+ logical processor." [#intel-ibpb-btb]_
+
+* On context switch and VMEXIT, user->kernel and guest->host RSB
+ underflows are mitigated by IBRS or eIBRS:
+
+ * "Enabling IBRS (including enhanced IBRS) will mitigate the "RSBU"
+ attack demonstrated by the researchers. As previously documented,
+ Intel recommends the use of enhanced IBRS, where supported. This
+ includes any processor that enumerates RRSBA but not RRSBA_DIS_S."
+ [#intel-rsbu]_
+
+ However, note that eIBRS and IBRS do not mitigate intra-mode attacks.
+ Like RRSBA below, this is mitigated by clearing the BHB on kernel
+ entry.
+
+ As an alternative to classic IBRS, call depth tracking (combined with
+ retpolines) can be used to track kernel returns and fill the RSB when
+ it gets close to being empty.
+
+Restricted RSB Alternate (RRSBA)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Some newer Intel CPUs have Restricted RSB Alternate (RRSBA) behavior,
+which, similar to RSBA described above, also falls back to using the BTB
+on RSB underflow. The only difference is that the predicted targets are
+restricted to the current domain when eIBRS is enabled:
+
+* "Restricted RSB Alternate (RRSBA) behavior allows alternate branch
+ predictors to be used by near RET instructions when the RSB is
+ empty. When eIBRS is enabled, the predicted targets of these
+ alternate predictors are restricted to those belonging to the
+ indirect branch predictor entries of the current prediction domain.
+ [#intel-eibrs-rrsba]_
+
+When a CPU with RRSBA is vulnerable to Branch History Injection
+[#bhi-paper]_ [#intel-bhi]_, an RSB underflow could be used for an
+intra-mode BTI attack. This is mitigated by clearing the BHB on
+kernel entry.
+
+However if the kernel uses retpolines instead of eIBRS, it needs to
+disable RRSBA:
+
+* "Where software is using retpoline as a mitigation for BHI or
+ intra-mode BTI, and the processor both enumerates RRSBA and
+ enumerates RRSBA_DIS controls, it should disable this behavior."
+ [#intel-retpoline-rrsba]_

+Speculative Return Stack Overflow (SRSO)
+========================================
+
+This is a mitigation for the speculative return stack overflow (SRSO)
+vulnerability found on AMD processors. The mechanism is by now the well
+known scenario of poisoning CPU functional units - the Branch Target
+Buffer (BTB) and Return Address Predictor (RAP) in this case - and then
+tricking the elevated privilege domain (the kernel) into leaking
+sensitive data.
+
+AMD CPUs predict RET instructions using a Return Address Predictor (aka
+Return Address Stack/Return Stack Buffer). In some cases, a non-architectural
+CALL instruction (i.e., an instruction predicted to be a CALL but is
+not actually a CALL) can create an entry in the RAP which may be used
+to predict the target of a subsequent RET instruction.
+
+The specific circumstances that lead to this varies by microarchitecture
+but the concern is that an attacker can mis-train the CPU BTB to predict
+non-architectural CALL instructions in kernel space and use this to
+control the speculative target of a subsequent kernel RET, potentially
+leading to information disclosure via a speculative side-channel.
+
+The issue is tracked under CVE-2023-20569.
+
+Affected processors
+-------------------
+
+AMD Zen, generations 1-4. That is, all families 0x17 and 0x19. Older
+processors have not been investigated.
+
+System information and options
+------------------------------
+
+First of all, it is required that the latest microcode be loaded for
+mitigations to be effective.
+
+The sysfs file showing SRSO mitigation status is:
+
+ /sys/devices/system/cpu/vulnerabilities/spec_rstack_overflow
+
+The possible values in this file are:
+
+ * 'Not affected':
+
+ The processor is not vulnerable
+
+* 'Vulnerable':
+
+ The processor is vulnerable and no mitigations have been applied.
+
+ * 'Vulnerable: No microcode':
+
+ The processor is vulnerable, no microcode extending IBPB
+ functionality to address the vulnerability has been applied.
+
+ * 'Vulnerable: Safe RET, no microcode':
+
+ The "Safe RET" mitigation (see below) has been applied to protect the
+ kernel, but the IBPB-extending microcode has not been applied. User
+ space tasks may still be vulnerable.
+
+ * 'Vulnerable: Microcode, no safe RET':
+
+ Extended IBPB functionality microcode patch has been applied. It does
+ not address User->Kernel and Guest->Host transitions protection but it
+ does address User->User and VM->VM attack vectors.
+
+ Note that User->User mitigation is controlled by how the IBPB aspect in
+ the Spectre v2 mitigation is selected:
+
+ * conditional IBPB:
+
+ where each process can select whether it needs an IBPB issued
+ around it PR_SPEC_DISABLE/_ENABLE etc, see :doc:`spectre`
+
+ * strict:
+
+ i.e., always on - by supplying spectre_v2_user=on on the kernel
+ command line
+
+ (spec_rstack_overflow=microcode)
+
+ * 'Mitigation: Safe RET':
+
+ Combined microcode/software mitigation. It complements the
+ extended IBPB microcode patch functionality by addressing
+ User->Kernel and Guest->Host transitions protection.
+
+ Selected by default or by spec_rstack_overflow=safe-ret
+
+ * 'Mitigation: IBPB':
+
+ Similar protection as "safe RET" above but employs an IBPB barrier on
+ privilege domain crossings (User->Kernel, Guest->Host).
+
+ (spec_rstack_overflow=ibpb)
+
+ * 'Mitigation: IBPB on VMEXIT':
+
+ Mitigation addressing the cloud provider scenario - the Guest->Host
+ transitions only.
+
+ (spec_rstack_overflow=ibpb-vmexit)
+
+ * 'Mitigation: Reduced Speculation':
+
+ This mitigation gets automatically enabled when the above one "IBPB on
+ VMEXIT" has been selected and the CPU supports the BpSpecReduce bit.
+
+ It gets automatically enabled on machines which have the
+ SRSO_USER_KERNEL_NO=1 CPUID bit. In that case, the code logic is to switch
+ to the above =ibpb-vmexit mitigation because the user/kernel boundary is
+ not affected anymore and thus "safe RET" is not needed.
+
+ After enabling the IBPB on VMEXIT mitigation option, the BpSpecReduce bit
+ is detected (functionality present on all such machines) and that
+ practically overrides IBPB on VMEXIT as it has a lot less performance
+ impact and takes care of the guest->host attack vector too.
+
+In order to exploit vulnerability, an attacker needs to:
+
+ - gain local access on the machine
+
+ - break kASLR
+
+ - find gadgets in the running kernel in order to use them in the exploit
+
+ - potentially create and pin an additional workload on the sibling
+ thread, depending on the microarchitecture (not necessary on fam 0x19)
+
+ - run the exploit
+
+Considering the performance implications of each mitigation type, the
+default one is 'Mitigation: safe RET' which should take care of most
+attack vectors, including the local User->Kernel one.
+
+As always, the user is advised to keep her/his system up-to-date by
+applying software updates regularly.
+
+The default setting will be reevaluated when needed and especially when
+new attack vectors appear.
+
+As one can surmise, 'Mitigation: safe RET' does come at the cost of some
+performance depending on the workload. If one trusts her/his userspace
+and does not want to suffer the performance impact, one can always
+disable the mitigation with spec_rstack_overflow=off.
+
+Similarly, 'Mitigation: IBPB' is another full mitigation type employing
+an indirect branch prediction barrier after having applied the required
+microcode patch for one's system. This mitigation comes also at
+a performance cost.
+
+Mitigation: Safe RET
+--------------------
+
+The mitigation works by ensuring all RET instructions speculate to
+a controlled location, similar to how speculation is controlled in the
+retpoline sequence. To accomplish this, the __x86_return_thunk forces
+the CPU to mispredict every function return using a 'safe return'
+sequence.
+
+To ensure the safety of this mitigation, the kernel must ensure that the
+safe return sequence is itself free from attacker interference. In Zen3
+and Zen4, this is accomplished by creating a BTB alias between the
+untraining function srso_alias_untrain_ret() and the safe return
+function srso_alias_safe_ret() which results in evicting a potentially
+poisoned BTB entry and using that safe one for all function returns.
+
+In older Zen1 and Zen2, this is accomplished using a reinterpretation
+technique similar to Retbleed one: srso_untrain_ret() and
+srso_safe_ret().
+
+Checking the safe RET mitigation actually works
+-----------------------------------------------
+
+In case one wants to validate whether the SRSO safe RET mitigation works
+on a kernel, one could use two performance counters
+
+* PMC_0xc8 - Count of RET/RET lw retired
+* PMC_0xc9 - Count of RET/RET lw retired mispredicted
+
+and compare the number of RETs retired properly vs those retired
+mispredicted, in kernel mode. Another way of specifying those events
+is::
+
+ # perf list ex_ret_near_ret
+
+ List of pre-defined events (to be used in -e or -M):
+
+ core:
+ ex_ret_near_ret
+ [Retired Near Returns]
+ ex_ret_near_ret_mispred
+ [Retired Near Returns Mispredicted]
+
+Either the command using the event mnemonics::
+
+ # perf stat -e ex_ret_near_ret:k -e ex_ret_near_ret_mispred:k sleep 10s
+
+or using the raw PMC numbers::
+
+ # perf stat -e cpu/event=0xc8,umask=0/k -e cpu/event=0xc9,umask=0/k sleep 10s
+
+should give the same amount. I.e., every RET retired should be
+mispredicted::
+
+ [root@brent: ~/kernel/linux/tools/perf> ./perf stat -e cpu/event=0xc8,umask=0/k -e cpu/event=0xc9,umask=0/k sleep 10s
+
+ Performance counter stats for 'sleep 10s':
+
+ 137,167 cpu/event=0xc8,umask=0/k
+ 137,173 cpu/event=0xc9,umask=0/k
+
+ 10.004110303 seconds time elapsed
+
+ 0.000000000 seconds user
+ 0.004462000 seconds sys
+
+vs the case when the mitigation is disabled (spec_rstack_overflow=off)
+or not functioning properly, showing usually a lot smaller number of
+mispredicted retired RETs vs the overall count of retired RETs during
+a workload::
+
+ [root@brent: ~/kernel/linux/tools/perf> ./perf stat -e cpu/event=0xc8,umask=0/k -e cpu/event=0xc9,umask=0/k sleep 10s

+VMSCAPE
+=======
+
+VMSCAPE is a vulnerability that may allow a guest to influence the branch
+prediction in host userspace. It particularly affects hypervisors like QEMU.
+
+Even if a hypervisor may not have any sensitive data like disk encryption keys,
+guest-userspace may be able to attack the guest-kernel using the hypervisor as
+a confused deputy.
+
+Affected processors
+-------------------
+
+The following CPU families are affected by VMSCAPE:
+
+**Intel processors:**
+ - Skylake generation (Parts without Enhanced-IBRS)
+ - Cascade Lake generation - (Parts affected by ITS guest/host separation)
+ - Alder Lake and newer (Parts affected by BHI)
+
+Note that, BHI affected parts that use BHB clearing software mitigation e.g.
+Icelake are not vulnerable to VMSCAPE.
+
+**AMD processors:**
+ - Zen series (families 0x17, 0x19, 0x1a)
+
+** Hygon processors:**
+ - Family 0x18
+
+Mitigation
+----------
+
+Conditional IBPB
+----------------
+
+Kernel tracks when a CPU has run a potentially malicious guest and issues an
+IBPB before the first exit to userspace after VM-exit. If userspace did not run
+between VM-exit and the next VM-entry, no IBPB is issued.
+
+Note that the existing userspace mitigation against Spectre-v2 is effective in
+protecting the userspace. They are insufficient to protect the userspace VMMs
+from a malicious guest. This is because Spectre-v2 mitigations are applied at
+context switch time, while the userspace VMM can run after a VM-exit without a
+context switch.
+
+Vulnerability enumeration and mitigation is not applied inside a guest. This is
+because nested hypervisors should already be deploying IBPB to isolate
+themselves from nested guests.
+
+SMT considerations
+------------------
+
+When Simultaneous Multi-Threading (SMT) is enabled, hypervisors can be
+vulnerable to cross-thread attacks. For complete protection against VMSCAPE
+attacks in SMT environments, STIBP should be enabled.
+
+The kernel will issue a warning if SMT is enabled without adequate STIBP
+protection. Warning is not issued when:
+
+- SMT is disabled
+- STIBP is enabled system-wide
+- Intel eIBRS is enabled (which implies STIBP protection)
+
+System information and options
+------------------------------
+
+The sysfs file showing VMSCAPE mitigation status is:
+
+ /sys/devices/system/cpu/vulnerabilities/vmscape
+
+The possible values in this file are:
+
+ * 'Not affected':
+
+ The processor is not vulnerable to VMSCAPE attacks.
+
+ * 'Vulnerable':
+
+ The processor is vulnerable and no mitigation has been applied.
+
+ * 'Mitigation: IBPB before exit to userspace':
+
+ Conditional IBPB mitigation is enabled. The kernel tracks when a CPU has
+ run a potentially malicious guest and issues an IBPB before the first
+ exit to userspace after VM-exit.
+
+ * 'Mitigation: IBPB on VMEXIT':
+
+ IBPB is issued on every VM-exit. This occurs when other mitigations like
+ RETBLEED or SRSO are already issuing IBPB on VM-exit.
+
+Mitigation control on the kernel command line
+----------------------------------------------
+
+The mitigation can be controlled via the ``vmscape=`` command line parameter:
+
+ * ``vmscape=off``:
+
+ Disable the VMSCAPE mitigation.
+
+ * ``vmscape=ibpb``:
+
+ Enable conditional IBPB mitigation (default when CONFIG_MITIGATION_VMSCAPE=y).
+
+ * ``vmscape=force``:
+
+ Force vulnerability detection and mitigation even on processors that are
+ not known to be affected.

I/O statistics fields
=====================
-Since 2.4.20 (and some versions before, with patches), and 2.5.45,
-more extensive disk statistics have been introduced to help measure disk
-activity. Tools such as ``sar`` and ``iostat`` typically interpret these and do
-the work for you, but in case you are interested in creating your own
-tools, the fields are explained here.
-
-In 2.4 now, the information is found as additional fields in
-``/proc/partitions``. In 2.6 and upper, the same information is found in two
-places: one is in the file ``/proc/diskstats``, and the other is within
-the sysfs file system, which must be mounted in order to obtain
-the information. Throughout this document we'll assume that sysfs
-is mounted on ``/sys``, although of course it may be mounted anywhere.
-Both ``/proc/diskstats`` and sysfs use the same source for the information
-and so should not differ.
-
-Here are examples of these different formats::
-
- 2.4:
- 3 0 39082680 hda 446216 784926 9550688 4382310 424847 312726 5922052 19310380 0 3376340 23705160

- 35486 38030 38030 38030

- 4.18+ diskstats:
- 3 0 hda 446216 784926 9550688 4382310 424847 312726 5922052 19310380 0 3376340 23705160 0 0 0 0
-
-On 2.4 you might execute ``grep 'hda ' /proc/partitions``. On 2.6+, you have
-a choice of ``cat /sys/block/hda/stat`` or ``grep 'hda ' /proc/diskstats``.
-
-The advantage of one over the other is that the sysfs choice works well
-if you are watching a known, small set of disks. ``/proc/diskstats`` may
-be a better choice if you are watching a large number of disks because
-you'll avoid the overhead of 50, 100, or 500 or more opens/closes with
-each snapshot of your disk statistics.
-
-In 2.4, the statistics fields are those after the device name. In
-the above example, the first field of statistics would be 446216.
-By contrast, in 2.6+ if you look at ``/sys/block/hda/stat``, you'll
-find just the 15 fields, beginning with 446216. If you look at
-``/proc/diskstats``, the 15 fields will be preceded by the major and
-minor device numbers, and device name. Each of these formats provides
-15 fields of statistics, each meaning exactly the same things.
-All fields except field 9 are cumulative since boot. Field 9 should
-go to zero as I/Os complete; all others only increase (unless they
-overflow and wrap). Wrapping might eventually occur on a very busy
-or long-lived system; so applications should be prepared to deal with
-it. Regarding wrapping, the types of the fields are either unsigned
-int (32 bit) or unsigned long (32-bit or 64-bit, depending on your
-machine) as noted per-field below. Unless your observations are very
-spread in time, these fields should not wrap twice before you notice it.
+The kernel exposes disk statistics via ``/proc/diskstats`` and
+``/sys/block/<device>/stat``. These stats are usually accessed via tools
+such as ``sar`` and ``iostat``.
+
+Here are examples using a disk with two partitions::
+

+
+Both files contain the same 17 statistics. ``/sys/block/<device>/stat``
+contains the fields for ``<device>``. In ``/proc/diskstats`` the fields
+are prefixed with the major and minor device numbers and the device
+name. In the example above, the first stat value for ``nvme0n1`` is
+255999 in both files.
+
+The sysfs ``stat`` file is efficient for monitoring a small, known set
+of disks. If you're tracking a large number of devices,
+``/proc/diskstats`` is often the better choice since it avoids the
+overhead of opening and closing multiple files for each snapshot.
+
+All fields are cumulative, monotonic counters, except for field 9, which
+resets to zero as I/Os complete. The remaining fields reset at boot, on
+device reattachment or reinitialization, or when the underlying counter
+overflows. Applications reading these counters should detect and handle
+resets when comparing stat snapshots.
Each set of stats only applies to the indicated device; if you want
system-wide stats you'll have to find all the devices and sum them all up.

+
+ If the ring buffer is used for persistent bootups and has events enabled,

+Alienware WMI Driver
+====================
+
+Kurt Borja <kuurtb@gmail.com>
+
+This is a driver for the "WMAX" WMI device, which is found in most Dell gaming
+laptops and controls various special features.
+
+Before the launch of M-Series laptops (~2018), the "WMAX" device controlled
+basic RGB lighting, deep sleep mode, HDMI mode and amplifier status.
+
+Later, this device was completely repurpused. Now it mostly deals with thermal
+profiles, sensor monitoring and overclocking. This interface is named "AWCC" and
+is known to be used by the AWCC OEM application to control these features.
+
+The alienware-wmi driver controls both interfaces.
+
+AWCC Interface
+==============
+
+WMI device documentation: Documentation/wmi/devices/alienware-wmi.rst
+
+Supported devices
+-----------------
+
+- Alienware M-Series laptops
+- Alienware X-Series laptops
+- Alienware Aurora Desktops
+- Dell G-Series laptops
+
+If you believe your device supports the AWCC interface and you don't have any of
+the features described in this document, try the following alienware-wmi module
+parameters:
+
+- ``force_platform_profile=1``: Forces probing for platform profile support
+- ``force_hwmon=1``: Forces probing for HWMON support
+
+If the module loads successfully with these parameters, consider submitting a
+patch adding your model to the ``awcc_dmi_table`` located in
+``drivers/platform/x86/dell/alienware-wmi-wmax.c`` or contacting the maintainer
+for further guidance.
+
+Status
+------
+
+The following features are currently supported:
+
+- :ref:`Platform Profile <platform-profile>`:
+
+ - Thermal profile control
+
+ - G-Mode toggling
+
+- :ref:`HWMON <hwmon>`:
+
+ - Sensor monitoring
+
+ - Manual fan control
+
+.. _platform-profile:
+
+Platform Profile
+----------------
+
+The AWCC interface exposes various firmware defined thermal profiles. These are
+exposed to user-space through the Platform Profile class interface. Refer to
+:ref:`sysfs-class-platform-profile <abi_file_testing_sysfs_class_platform_profile>`
+for more information.
+
+The name of the platform-profile class device exported by this driver is
+"alienware-wmi" and it's path can be found with:
+
+::
+
+ grep -l "alienware-wmi" /sys/class/platform-profile/platform-profile-*/name | sed 's|/[^/]*$||'
+
+If the device supports G-Mode, it is also toggled when selecting the
+``performance`` profile.
+
+.. note::
+ You may set the ``force_gmode`` module parameter to always try to toggle this
+ feature, without checking if your model supports it.
+
+.. _hwmon:
+
+HWMON
+-----
+
+The AWCC interface also supports sensor monitoring and manual fan control. Both
+of these features are exposed to user-space through the HWMON interface.
+
+The name of the hwmon class device exported by this driver is "alienware_wmi"
+and it's path can be found with:
+
+::
+
+ grep -l "alienware_wmi" /sys/class/hwmon/hwmon*/name | sed 's|/[^/]*$||'
+
+Sensor monitoring is done through the standard HWMON interface. Refer to
+:ref:`sysfs-class-hwmon <abi_file_testing_sysfs_class_hwmon>` for more
+information.
+
+Manual fan control on the other hand, is not exposed directly by the AWCC
+interface. Instead it let's us control a fan `boost` value. This `boost` value
+has the following aproximate behavior over the fan pwm:
+
+::
+
+ pwm = pwm_base + (fan_boost / 255) * (pwm_max - pwm_base)
+
+Due to the above behavior, the fan `boost` control is exposed to user-space
+through the following, custom hwmon sysfs attribute:
+
+=============================== ======= =======================================
+Name Perm Description
+=============================== ======= =======================================
+fan[1-4]_boost RW Fan boost value.
+
+ Integer value between 0 and 255
+=============================== ======= =======================================
+
+.. note::
+ In some devices, manual fan control only works reliably if the ``custom``
+ platform profile is selected.

+extra features and receive various notifications.
+
+Supported devices
+=================
+
+Any device with one of the supported ACPI device IDs should be supported. This
+covers most of the "Samsung Galaxy Book" series notebooks that are currently
+available as of this writing, and could include other Samsung notebook devices
+as well.
+
+Status
+======
+
+The following features are currently supported:
+
+- :ref:`Keyboard backlight <keyboard-backlight>` control
+- :ref:`Performance mode <performance-mode>` control implemented using the
+ platform profile interface
+- :ref:`Battery charge control end threshold
+ <battery-charge-control-end-threshold>` (stop charging battery at given
+ percentage value) implemented as a battery hook
+- :ref:`Firmware Attributes <firmware-attributes>` to allow control of various
+ device settings
+- :ref:`Handling of Fn hotkeys <keyboard-hotkey-actions>` for various actions
+- :ref:`Handling of ACPI notifications and hotkeys
+ <acpi-notifications-and-hotkey-actions>`
+
+Because different models of these devices can vary in their features, there is
+logic built within the driver which attempts to test each implemented feature
+for a valid response before enabling its support (registering additional devices
+or extensions, adding sysfs attributes, etc). Therefore, it can be important to
+note that not all features may be supported for your particular device.
+
+The following features might be possible to implement but will require
+additional investigation and are therefore not supported at this time:
+
+- "Dolby Atmos" mode for the speakers
+- "Outdoor Mode" for increasing screen brightness on models with ``SAM0427``
+- "Silent Mode" on models with ``SAM0427``
+
+.. _keyboard-backlight:
+
+Keyboard backlight
+==================
+
+A new LED class named ``samsung-galaxybook::kbd_backlight`` is created which
+will then expose the device using the standard sysfs-based LED interface at
+``/sys/class/leds/samsung-galaxybook::kbd_backlight``. Brightness can be
+controlled by writing the desired value to the ``brightness`` sysfs attribute or
+with any other desired userspace utility.
+
+.. note::
+ Most of these devices have an ambient light sensor which also turns
+ off the keyboard backlight under well-lit conditions. This behavior does not
+ seem possible to control at this time, but can be good to be aware of.
+
+.. _performance-mode:
+
+Performance mode
+================
+
+This driver implements the
+Documentation/userspace-api/sysfs-platform_profile.rst interface for working
+with the "performance mode" function of the Samsung ACPI device.
+
+Mapping of each Samsung "performance mode" to its respective platform profile is
+performed dynamically by the driver, as not all models support all of the same
+performance modes. Your device might have one or more of the following mappings:
+
+- "Silent" maps to ``low-power``
+- "Quiet" maps to ``quiet``
+- "Optimized" maps to ``balanced``
+- "High performance" maps to ``performance``
+
+The result of the mapping can be printed in the kernel log when the module is
+loaded. Supported profiles can also be retrieved from
+``/sys/firmware/acpi/platform_profile_choices``, while
+``/sys/firmware/acpi/platform_profile`` can be used to read or write the
+currently selected profile.
+
+The ``balanced`` platform profile will be set during module load if no profile
+has been previously set.
+
+.. _battery-charge-control-end-threshold:
+
+Battery charge control end threshold
+====================================
+
+This platform driver will add the ability to set the battery's charge control
+end threshold, but does not have the ability to set a start threshold.
+
+This feature is typically called "Battery Saver" by the various Samsung
+applications in Windows, but in Linux we have implemented the standardized
+"charge control threshold" sysfs interface on the battery device to allow for
+controlling this functionality from the userspace.
+
+The sysfs attribute
+``/sys/class/power_supply/BAT1/charge_control_end_threshold`` can be used to
+read or set the desired charge end threshold.
+
+If you wish to maintain interoperability with the Samsung Settings application
+in Windows, then you should set the value to 100 to represent "off", or enable
+the feature using only one of the following values: 50, 60, 70, 80, or 90.
+Otherwise, the driver will accept any value between 1 and 100 as the percentage
+that you wish the battery to stop charging at.
+
+.. note::
+ Some devices have been observed as automatically "turning off" the charge
+ control end threshold if an input value of less than 30 is given.
+
+.. _firmware-attributes:
+
+Firmware Attributes
+===================
+
+The following enumeration-typed firmware attributes are set up by this driver
+and should be accessible under
+``/sys/class/firmware-attributes/samsung-galaxybook/attributes/`` if your device
+supports them:
+
+- ``power_on_lid_open`` (device should power on when the lid is opened)
+- ``usb_charging`` (USB ports can deliver power to connected devices even when
+ the device is powered off or in a low sleep state)
+- ``block_recording`` (blocks access to camera and microphone)
+
+All of these attributes are simple boolean-like enumeration values which use 0
+to represent "off" and 1 to represent "on". Use the ``current_value`` attribute
+to get or change the setting on the device.
+
+Note that when ``block_recording`` is updated, the input device "Samsung Galaxy
+Book Lens Cover" will receive a ``SW_CAMERA_LENS_COVER`` switch event which
+reflects the current state.
+
+.. _keyboard-hotkey-actions:
+
+Keyboard hotkey actions (i8042 filter)
+======================================
+
+The i8042 filter will swallow the keyboard events for the Fn+F9 hotkey (Multi-
+level keyboard backlight toggle) and Fn+F10 hotkey (Block recording toggle)
+and instead execute their actions within the driver itself.
+
+Fn+F9 will cycle through the brightness levels of the keyboard backlight. A
+notification will be sent using ``led_classdev_notify_brightness_hw_changed``
+so that the userspace can be aware of the change. This mimics the behavior of
+other existing devices where the brightness level is cycled internally by the
+embedded controller and then reported via a notification.
+
+Fn+F10 will toggle the value of the "block recording" setting, which blocks
+or allows usage of the built-in camera and microphone (and generates the same
+Lens Cover switch event mentioned above).
+
+.. _acpi-notifications-and-hotkey-actions:
+
+ACPI notifications and hotkey actions
+=====================================
+
+ACPI notifications will generate ACPI netlink events under the device class
+``samsung-galaxybook`` and bus ID matching the Samsung ACPI device ID found on
+your device. The events can be received using userspace tools such as
+``acpi_listen`` and ``acpid``.
+
+The Fn+F11 Performance mode hotkey will be handled by the driver; each keypress
+will cycle to the next available platform profile.

+Uniwill laptop extra features
+=============================
+
+On laptops manufactured by Uniwill (either directly or as ODM), the ``uniwill-laptop`` driver
+handles various platform-specific features.
+
+Module Loading
+--------------
+
+The ``uniwill-laptop`` driver relies on a DMI table to automatically load on supported devices.
+When using the ``force`` module parameter, this DMI check will be omitted, allowing the driver
+to be loaded on unsupported devices for testing purposes.
+
+Hotkeys
+-------
+
+Usually the FN keys work without a special driver. However as soon as the ``uniwill-laptop`` driver
+is loaded, the FN keys need to be handled manually. This is done automatically by the driver itself.
+
+Keyboard settings
+-----------------
+
+The ``uniwill-laptop`` driver allows the user to enable/disable:
+
+ - the FN and super key lock functionality of the integrated keyboard
+ - the touchpad toggle functionality of the integrated touchpad
+
+See Documentation/ABI/testing/sysfs-driver-uniwill-laptop for details.
+
+Hwmon interface
+---------------
+
+The ``uniwill-laptop`` driver supports reading of the CPU and GPU temperature and supports up to
+two fans. Userspace applications can access sensor readings over the hwmon sysfs interface.
+
+Platform profile
+----------------
+
+Support for changing the platform performance mode is currently not implemented.
+
+Battery Charging Control
+------------------------
+
+The ``uniwill-laptop`` driver supports controlling the battery charge limit. This happens over
+the standard ``charge_control_end_threshold`` power supply sysfs attribute. All values
+between 1 and 100 percent are supported.
+
+Additionally the driver signals the presence of battery charging issues through the standard
+``health`` power supply sysfs attribute.
+
+Lightbar
+--------
+
+The ``uniwill-laptop`` driver exposes the lightbar found on some models as a standard multicolor
+LED class device. The default name of this LED class device is ``uniwill:multicolor:status``.
+
+See Documentation/ABI/testing/sysfs-driver-uniwill-laptop for details on how to control the various
+animation modes of the lightbar.

+Amlogic C3 Image Signal Processing (C3ISP) driver
+=================================================
+
+Introduction
+============
+
+This file documents the Amlogic C3ISP driver located under
+drivers/media/platform/amlogic/c3/isp.
+
+The current version of the driver supports the C3ISP found on
+Amlogic C308L processor.
+
+The driver implements V4L2, Media controller and V4L2 subdev interfaces.
+Camera sensor using V4L2 subdev interface in the kernel is supported.
+
+The driver has been tested on AW419-C308L-Socket platform.
+
+Amlogic C3 ISP
+==============
+
+The Camera hardware found on C308L processors and supported by
+the driver consists of:
+
+- 1 MIPI-CSI-2 module: handles the physical layer of the MIPI CSI-2 receiver and
+ receives data from the connected camera sensor.
+- 1 MIPI-ADAPTER module: organizes MIPI data to meet ISP input requirements and
+ send MIPI data to ISP.
+- 1 ISP (Image Signal Processing) module: contains a pipeline of image processing
+ hardware blocks. The ISP pipeline contains three resizers at the end each of
+ them connected to a DMA interface which writes the output data to memory.
+
+A high-level functional view of the C3 ISP is presented below.::
+
+ +----------+ +-------+

+ +----------+ +-------+
+ |----------+ +-------+
+ | Resizer |--->| WRMIF |
+ +----------+ +-------+
+
+Driver architecture and design
+==============================
+
+With the goal to model the hardware links between the modules and to expose a
+clean, logical and usable interface, the driver registers the following V4L2
+sub-devices:
+
+- 1 `c3-mipi-csi2` sub-device - the MIPI CSI-2 receiver
+- 1 `c3-mipi-adapter` sub-device - the MIPI adapter
+- 1 `c3-isp-core` sub-device - the ISP core
+- 3 `c3-isp-resizer` sub-devices - the ISP resizers
+
+The `c3-isp-core` sub-device is linked to 2 video device nodes for statistics
+capture and parameters programming:
+
+- the `c3-isp-stats` capture video device node for statistics capture
+- the `c3-isp-params` output video device for parameters programming
+
+Each `c3-isp-resizer` sub-device is linked to a capture video device node where
+frames are captured from:
+
+- `c3-isp-resizer0` is linked to the `c3-isp-cap0` capture video device
+- `c3-isp-resizer1` is linked to the `c3-isp-cap1` capture video device
+- `c3-isp-resizer2` is linked to the `c3-isp-cap2` capture video device
+
+The media controller pipeline graph is as follows (with connected a
+IMX290 camera sensor):
+
+.. _isp_topology_graph:
+
+.. kernel-figure:: c3-isp.dot
+ :alt: c3-isp.dot
+ :align: center
+
+ Media pipeline topology
+
+Implementation
+==============
+
+Runtime configuration of the ISP hardware is performed on the `c3-isp-params`
+video device node using the :ref:`V4L2_META_FMT_C3ISP_PARAMS
+<v4l2-meta-fmt-c3isp-params>` as data format. The buffer structure is defined by
+:c:type:`c3_isp_params_cfg`.
+
+Statistics are captured from the `c3-isp-stats` video device node using the
+:ref:`V4L2_META_FMT_C3ISP_STATS <v4l2-meta-fmt-c3isp-stats>` data format.
+
+The final picture size and format is configured using the V4L2 video
+capture interface on the `c3-isp-cap[0, 2]` video device nodes.
+
+The Amlogic C3 ISP is supported by `libcamera <https://libcamera.org>`_ with a
+dedicated pipeline handler and algorithms that perform run-time image correction
+and enhancement.

+Extron DA HD 4K PLUS CEC Adapter driver
+=======================================
+
+This driver is for the Extron DA HD 4K PLUS series of HDMI Distribution
+Amplifiers: https://www.extron.com/product/dahd4kplusseries
+
+The 2, 4 and 6 port models are supported.
+
+Firmware version 1.02.0001 or higher is required.
+
+Note that older Extron hardware revisions have a problem with the CEC voltage,
+which may mean that CEC will not work. This is fixed in hardware revisions
+E34814 and up.
+
+The CEC support has two modes: the first is a manual mode where userspace has
+to manually control CEC for the HDMI Input and all HDMI Outputs. While this gives
+full control, it is also complicated.
+
+The second mode is an automatic mode, which is selected if the module option
+``vendor_id`` is set. In that case the driver controls CEC and CEC messages
+received in the input will be distributed to the outputs. It is still possible
+to use the /dev/cecX devices to talk to the connected devices directly, but it is
+the driver that configures everything and deals with things like Hotplug Detect
+changes.
+
+The driver also takes care of the EDIDs: /dev/videoX devices are created to
+read the EDIDs and (for the HDMI Input port) to set the EDID.
+
+By default userspace is responsible to set the EDID for the HDMI Input
+according to the EDIDs of the connected displays. But if the ``manufacturer_name``
+module option is set, then the driver will take care of setting the EDID
+of the HDMI Input based on the supported resolutions of the connected displays.
+Currently the driver only supports resolutions 1080p60 and 4kp60: if all connected
+displays support 4kp60, then it will advertise 4kp60 on the HDMI input, otherwise
+it will fall back to an EDID that just reports 1080p60.
+
+The status of the Extron is reported in ``/sys/kernel/debug/cec/cecX/status``.
+
+The extron-da-hd-4k-plus driver implements the following module options:
+
+``debug``
+---------
+
+If set to 1, then all serial port traffic is shown.
+
+``vendor_id``
+-------------
+
+The CEC Vendor ID to report to connected displays.
+
+If set, then the driver will take care of distributing CEC messages received
+on the input to the HDMI outputs. This is done for the following CEC messages:
+
+- <Standby>
+- <Image View On> and <Text View On>
+- <Give Device Power Status>
+- <Set System Audio Mode>
+- <Request Current Latency>
+
+If not set, then userspace is responsible for this, and it will have to
+configure the CEC devices for HDMI Input and the HDMI Outputs manually.
+
+``manufacturer_name``
+---------------------
+
+A three character manufacturer name that is used in the EDID for the HDMI
+Input. If not set, then userspace is responsible for configuring an EDID.
+If set, then the driver will update the EDID automatically based on the
+resolutions supported by the connected displays, and it will not be possible
+anymore to manually set the EDID for the HDMI Input.
+
+``hpd_never_low``
+-----------------
+
+If set, then the Hotplug Detect pin of the HDMI Input will always be high,
+even if nothing is connected to the HDMI Outputs. If not set (the default)
+then the Hotplug Detect pin of the HDMI input will go low if all the detected
+Hotplug Detect pins of the HDMI Outputs are also low.
+
+This option may be changed dynamically.

+
+Introduction
+============
+
+This file documents the Intel IPU6 (6th generation Image Processing Unit)
+Input System (MIPI CSI2 receiver) drivers located under
+drivers/media/pci/intel/ipu6.
+
+The Intel IPU6 can be found in certain Intel SoCs but not in all SKUs:
+
+* Tiger Lake
+* Jasper Lake
+* Alder Lake
+* Raptor Lake
+* Meteor Lake
+
+Intel IPU6 is made up of two components - Input System (ISYS) and Processing
+System (PSYS).
+
+The Input System mainly works as MIPI CSI-2 receiver which receives and
+processes the image data from the sensors and outputs the frames to memory.
+
+There are 2 driver modules - intel-ipu6 and intel-ipu6-isys. intel-ipu6 is an
+IPU6 common driver which does PCI configuration, firmware loading and parsing,
+firmware authentication, DMA mapping and IPU-MMU (internal Memory mapping Unit)
+configuration. intel_ipu6_isys implements V4L2, Media Controller and V4L2
+sub-device interfaces. The IPU6 ISYS driver supports camera sensors connected
+to the IPU6 ISYS through V4L2 sub-device sensor drivers.
+
+.. Note:: See Documentation/driver-api/media/drivers/ipu6.rst for more
+ information about the IPU6 hardware.
+
+Input system driver
+===================
+
+The Input System driver mainly configures CSI-2 D-PHY, constructs the firmware
+stream configuration, sends commands to firmware, gets response from hardware
+and firmware and then returns buffers to user. The ISYS is represented as
+several V4L2 sub-devices as well as video nodes.

+Capturing frames with IPU6 ISYS
+-------------------------------
+
+IPU6 ISYS is used to capture frames from the camera sensors connected to the
+CSI2 ports. The supported input formats of ISYS are listed in table below:
+
+.. tabularcolumns:: |p{0.8cm}|p{4.0cm}|p{4.0cm}|
+
+.. flat-table::
+ :header-rows: 1
+
+ * - IPU6 ISYS supported input formats

+
+Examples
+~~~~~~~~
+
+Here is an example of IPU6 ISYS raw capture on Dell XPS 9315 laptop. On this
+machine, ov01a10 sensor is connected to IPU ISYS CSI-2 port 2, which can
+generate images at sBGGR10 with resolution 1280x800.
+
+Using the media controller APIs, we can configure ov01a10 sensor by
+media-ctl [#f1]_ and yavta [#f2]_ to transmit frames to IPU6 ISYS.
+
+.. code-block:: none
+
+ # Example 1 capture frame from ov01a10 camera sensor
+ # This example assumes /dev/media0 as the IPU ISYS media device
+ export MDEV=/dev/media0
+
+ # Establish the link for the media devices using media-ctl
+ media-ctl -d $MDEV -l "\"ov01a10 3-0036\":0 -> \"Intel IPU6 CSI2 2\":0[1]"
+
+ # Set the format for the media devices
+ media-ctl -d $MDEV -V "ov01a10:0 [fmt:SBGGR10/1280x800]"
+ media-ctl -d $MDEV -V "Intel IPU6 CSI2 2:0 [fmt:SBGGR10/1280x800]"
+ media-ctl -d $MDEV -V "Intel IPU6 CSI2 2:1 [fmt:SBGGR10/1280x800]"
+
+Once the media pipeline is configured, desired sensor specific settings
+(such as exposure and gain settings) can be set, using the yavta tool.
+
+e.g
+
+.. code-block:: none
+
+ # and that ov01a10 sensor is connected to i2c bus 3 with address 0x36
+ export SDEV=$(media-ctl -d $MDEV -e "ov01a10 3-0036")
+
+ yavta -w 0x009e0903 400 $SDEV
+ yavta -w 0x009e0913 1000 $SDEV
+ yavta -w 0x009e0911 2000 $SDEV
+
+Once the desired sensor settings are set, frame captures can be done as below.
+
+e.g
+
+.. code-block:: none
+
+ yavta --data-prefix -u -c10 -n5 -I -s 1280x800 --file=/tmp/frame-#.bin \
+ -f SBGGR10 $(media-ctl -d $MDEV -e "Intel IPU6 ISYS Capture 0")
+
+With the above command, 10 frames are captured at 1280x800 resolution with
+sBGGR10 format. The captured frames are available as /tmp/frame-#.bin files.
+
+Here is another example of IPU6 ISYS RAW and metadata capture from camera
+sensor ov2740 on Lenovo X1 Yoga laptop.
+
+.. code-block:: none
+
+ media-ctl -l "\"ov2740 14-0036\":0 -> \"Intel IPU6 CSI2 1\":0[1]"
+ media-ctl -l "\"Intel IPU6 CSI2 1\":1 -> \"Intel IPU6 ISYS Capture 0\":0[1]"
+ media-ctl -l "\"Intel IPU6 CSI2 1\":2 -> \"Intel IPU6 ISYS Capture 1\":0[1]"
+
+ # set routing
+ media-ctl -R "\"Intel IPU6 CSI2 1\" [0/0->1/0[1],0/1->2/1[1]]"
+
+ media-ctl -V "\"Intel IPU6 CSI2 1\":0/0 [fmt:SGRBG10/1932x1092]"
+ media-ctl -V "\"Intel IPU6 CSI2 1\":0/1 [fmt:GENERIC_8/97x1]"
+ media-ctl -V "\"Intel IPU6 CSI2 1\":1/0 [fmt:SGRBG10/1932x1092]"
+ media-ctl -V "\"Intel IPU6 CSI2 1\":2/1 [fmt:GENERIC_8/97x1]"
+
+ CAPTURE_DEV=$(media-ctl -e "Intel IPU6 ISYS Capture 0")
+ ./yavta --data-prefix -c100 -n5 -I -s1932x1092 --file=/tmp/frame-#.bin \

+ARM Mali-C55 Image Signal Processor driver
+==========================================
+
+Introduction
+============
+
+This file documents the driver for ARM's Mali-C55 Image Signal Processor. The
+driver is located under drivers/media/platform/arm/mali-c55.
+
+The Mali-C55 ISP receives data in either raw Bayer format or RGB/YUV format from
+sensors through either a parallel interface or a memory bus before processing it
+and outputting it through an internal DMA engine. Two output pipelines are
+possible (though one may not be fitted, depending on the implementation). These
+are referred to as "Full resolution" and "Downscale", but the naming is historic
+and both pipes are capable of cropping/scaling operations. The full resolution
+pipe is also capable of outputting RAW data, bypassing much of the ISP's
+processing. The downscale pipe cannot output RAW data. An integrated test
+pattern generator can be used to drive the ISP and produce image data in the
+absence of a connected camera sensor. The driver module is named mali_c55, and
+is enabled through the CONFIG_VIDEO_MALI_C55 config option.
+
+The driver implements V4L2, Media Controller and V4L2 Subdevice interfaces and
+expects camera sensors connected to the ISP to have V4L2 subdevice interfaces.
+
+Mali-C55 ISP hardware
+=====================
+
+A high level functional view of the Mali-C55 ISP is presented below. The ISP
+takes input from either a live source or through a DMA engine for memory input,
+depending on the SoC integration.::
+

+ | +--------+

+ Output +--------+
+
+Media Controller Topology
+=========================
+
+An example of the ISP's topology (as implemented in a system with an IMX415
+camera sensor and generic CSI-2 receiver) is below:
+
+
+.. kernel-figure:: mali-c55-graph.dot
+ :alt: mali-c55-graph.dot
+ :align: center
+
+The driver has 4 V4L2 subdevices:
+
+- `mali_c55 isp`: Responsible for configuring input crop and color space
+ conversion
+- `mali_c55 tpg`: The test pattern generator, emulating a camera sensor.
+- `mali_c55 resizer fr`: The Full-Resolution pipe resizer
+- `mali_c55 resizer ds`: The Downscale pipe resizer
+
+The driver has 3 V4L2 video devices:
+
+- `mali-c55 fr`: The full-resolution pipe's capture device
+- `mali-c55 ds`: The downscale pipe's capture device
+- `mali-c55 3a stats`: The 3A statistics capture device
+
+Frame sequences are synchronised across to two capture devices, meaning if one
+pipe is started later than the other the sequence numbers returned in its
+buffers will match those of the other pipe rather than starting from zero.
+
+Idiosyncrasies
+--------------
+
+**mali-c55 isp**
+The `mali-c55 isp` subdevice has a single sink pad to which all sources of data
+should be connected. The active source is selected by enabling the appropriate
+media link and disabling all others. The ISP has two source pads, reflecting the
+different paths through which it can internally route data. Tap points within
+the ISP allow users to divert data to avoid processing by some or all of the
+hardware's processing steps. The diagram below is intended only to highlight how
+the bypassing works and is not a true reflection of those processing steps; for
+a high-level functional block diagram see ARM's developer page for the
+ISP [3]_::

+ - RAW bayer data, connected to the FR V4L2 subdevices
+
+The ISP is limited to both input and output resolutions between 640x480 and
+8192x8192, and this is reflected in the ISP and resizer subdevice's .set_fmt()
+operations.
+
+**mali-c55 resizer fr**
+The `mali-c55 resizer fr` subdevice has two _sink_ pads to reflect the different
+insertion points in the hardware (either RAW or demosaiced data):
+
+.. flat-table::
+ :header-rows: 1
+
+ * - Pad
+ - Direction
+ - Purpose
+
+ * - 0
+ - sink

+
+ * - 1
+ - source
+ - Data output connected to the capture video device
+
+ * - 2
+ - sink
+ - Data input connected to the ISP's raw data stream
+
+The data source in use is selected through the routing API; two routes each of a
+single stream are available:
+
+.. flat-table::
+ :header-rows: 1
+
+ * - Sink Pad
+ - Source Pad
+ - Purpose
+
+ * - 0
+ - 1
+ - Demosaiced data route
+
+ * - 2
+ - 1
+ - Raw data route
+
+
+If the demosaiced route is active then the FR pipe is only capable of output
+in RGB/YUV formats. If the raw route is active then the output reflects the
+input (which may be either Bayer or RGB/YUV data).
+
+Using the driver to capture video
+=================================
+
+Using the media controller APIs we can configure the input source and ISP to
+capture images in a variety of formats. In the examples below, configuring the
+media graph is done with the v4l-utils [1]_ package's media-ctl utility.
+Capturing the images is done with yavta [2]_.
+
+Configuring the input source
+----------------------------
+
+The first step is to set the input source that we wish by enabling the correct
+media link. Using the example topology above, we can select the TPG as follows:
+
+.. code-block:: none
+
+ media-ctl -l "'lte-csi2-rx':1->'mali-c55 isp':0[0]"
+ media-ctl -l "'mali-c55 tpg':0->'mali-c55 isp':0[1]"
+
+Configuring which video devices will stream data
+------------------------------------------------
+
+The driver will wait for all video devices to have their VIDIOC_STREAMON ioctl
+called before it tells the sensor to start streaming. To facilitate this we need
+to enable links to the video devices that we want to use. In the example below
+we enable the links to both of the image capture video devices
+
+.. code-block:: none
+
+ media-ctl -l "'mali-c55 resizer fr':1->'mali-c55 fr':0[1]"
+ media-ctl -l "'mali-c55 resizer ds':1->'mali-c55 ds':0[1]"
+
+Capturing bayer data from the source and processing to RGB/YUV
+--------------------------------------------------------------
+
+To capture 1920x1080 bayer data from the source and push it through the ISP's
+full processing pipeline, we configure the data formats appropriately on the
+source, ISP and resizer subdevices and set the FR resizer's routing to select
+processed data. The media bus format on the resizer's source pad will be either
+RGB121212_1X36 or YUV10_1X30, depending on whether you want to capture RGB or
+YUV. The ISP's debayering block outputs RGB data natively, setting the source
+pad format to YUV10_1X30 enables the colour space conversion block.
+
+In this example we target RGB565 output, so select RGB121212_1X36 as the resizer
+source pad's format:
+
+.. code-block:: none
+
+ # Set formats on the TPG and ISP
+ media-ctl -V "'mali-c55 tpg':0[fmt:SRGGB20_1X20/1920x1080]"
+ media-ctl -V "'mali-c55 isp':0[fmt:SRGGB20_1X20/1920x1080]"
+ media-ctl -V "'mali-c55 isp':1[fmt:SRGGB20_1X20/1920x1080]"
+
+ # Set routing on the FR resizer
+ media-ctl -R "'mali-c55 resizer fr'[0/0->1/0[1],2/0->1/0[0]]"
+
+ # Set format on the resizer, must be done AFTER the routing.
+ media-ctl -V "'mali-c55 resizer fr':1[fmt:RGB121212_1X36/1920x1080]"
+
+The downscale output can also be used to stream data at the same time. In this
+case since only processed data can be captured through the downscale output no
+routing need be set:
+
+.. code-block:: none
+
+ # Set format on the resizer
+ media-ctl -V "'mali-c55 resizer ds':1[fmt:RGB121212_1X36/1920x1080]"
+
+Following which images can be captured from both the FR and DS output's video
+devices (simultaneously, if desired):
+
+.. code-block:: none
+
+ yavta -f RGB565 -s 1920x1080 -c10 /dev/video0
+ yavta -f RGB565 -s 1920x1080 -c10 /dev/video1
+
+Cropping the image
+~~~~~~~~~~~~~~~~~~
+
+Both the full resolution and downscale pipes can crop to a minimum resolution of
+640x480. To crop the image simply configure the resizer's sink pad's crop and
+compose rectangles and set the format on the video device:
+
+.. code-block:: none
+
+ media-ctl -V "'mali-c55 resizer fr':0[fmt:RGB121212_1X36/1920x1080 crop:(480,270)/640x480 compose:(0,0)/640x480]"
+ media-ctl -V "'mali-c55 resizer fr':1[fmt:RGB121212_1X36/640x480]"
+ yavta -f RGB565 -s 640x480 -c10 /dev/video0
+
+Downscaling the image
+~~~~~~~~~~~~~~~~~~~~~
+
+Both the full resolution and downscale pipes can downscale the image by up to 8x
+provided the minimum 640x480 output resolution is adhered to. For the best image
+result the scaling ratio for each direction should be the same. To configure
+scaling we use the compose rectangle on the resizer's sink pad:
+
+.. code-block:: none
+
+ media-ctl -V "'mali-c55 resizer fr':0[fmt:RGB121212_1X36/1920x1080 crop:(0,0)/1920x1080 compose:(0,0)/640x480]"
+ media-ctl -V "'mali-c55 resizer fr':1[fmt:RGB121212_1X36/640x480]"
+ yavta -f RGB565 -s 640x480 -c10 /dev/video0
+
+Capturing images in YUV formats
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If we need to output YUV data rather than RGB the color space conversion block
+needs to be active, which is achieved by setting MEDIA_BUS_FMT_YUV10_1X30 on the
+resizer's source pad. We can then configure a capture format like NV12 (here in
+its multi-planar variant)
+
+.. code-block:: none
+
+ media-ctl -V "'mali-c55 resizer fr':1[fmt:YUV10_1X30/1920x1080]"
+ yavta -f NV12M -s 1920x1080 -c10 /dev/video0
+
+Capturing RGB data from the source and processing it with the resizers
+----------------------------------------------------------------------
+
+The Mali-C55 ISP can work with sensors capable of outputting RGB data. In this
+case although none of the image quality blocks would be used it can still
+crop/scale the data in the usual way. For this reason RGB data input to the ISP
+still goes through the ISP subdevice's pad 1 to the resizer.
+
+To achieve this, the ISP's sink pad's format is set to
+MEDIA_BUS_FMT_RGB202020_1X60 - this reflects the format that data must be in to
+work with the ISP. Converting the camera sensor's output to that format is the
+responsibility of external hardware.
+
+In this example we ask the test pattern generator to give us RGB data instead of
+bayer.
+
+.. code-block:: none
+
+ media-ctl -V "'mali-c55 tpg':0[fmt:RGB202020_1X60/1920x1080]"
+ media-ctl -V "'mali-c55 isp':0[fmt:RGB202020_1X60/1920x1080]"
+
+Cropping or scaling the data can be done in exactly the same way as outlined
+earlier.
+
+Capturing raw data from the source and outputting it unmodified
+-----------------------------------------------------------------
+
+The ISP can additionally capture raw data from the source and output it on the
+full resolution pipe only, completely unmodified. In this case the downscale
+pipe can still process the data normally and be used at the same time.
+
+To configure raw bypass the FR resizer's subdevice's routing table needs to be
+configured, followed by formats in the appropriate places:
+
+.. code-block:: none
+
+ media-ctl -R "'mali-c55 resizer fr'[0/0->1/0[0],2/0->1/0[1]]"
+ media-ctl -V "'mali-c55 isp':0[fmt:RGB202020_1X60/1920x1080]"
+ media-ctl -V "'mali-c55 resizer fr':2[fmt:RGB202020_1X60/1920x1080]"
+ media-ctl -V "'mali-c55 resizer fr':1[fmt:RGB202020_1X60/1920x1080]"
+
+ # Set format on the video device and stream
+ yavta -f RGB565 -s 1920x1080 -c10 /dev/video0
+
+.. _mali-c55-3a-stats:
+
+Capturing ISP Statistics
+========================
+
+The ISP is capable of producing statistics for consumption by image processing
+algorithms running in userspace. These statistics can be captured by queueing
+buffers to the `mali-c55 3a stats` V4L2 Device whilst the ISP is streaming. Only
+the :ref:`V4L2_META_FMT_MALI_C55_STATS <v4l2-meta-fmt-mali-c55-stats>`
+format is supported, so no format-setting need be done:
+
+.. code-block:: none
+
+ # We assume the media graph has been configured to support RGB565 capture
+ # from the mali-c55 fr V4L2 Device, which is at /dev/video0. The statistics
+ # V4L2 device is at /dev/video3
+
+ yavta -f RGB565 -s 1920x1080 -c32 /dev/video0 && \
+ yavta -c10 -F /dev/video3
+
+The layout of the buffer is described by :c:type:`mali_c55_stats_buffer`,
+but broadly statistics are generated to support three image processing
+algorithms; AEXP (Auto-Exposure), AWB (Auto-White Balance) and AF (Auto-Focus).
+These stats can be drawn from various places in the Mali C55 ISP pipeline, known
+as "tap points". This high-level block diagram is intended to explain where in
+the processing flow the statistics can be drawn from::
+
+ +--> AEXP-2 +----> AEXP-1 +--> AF-0
+ | +----> AF-1 |
+ | | |
+ +---------+ | +--------------+ | +--------------+ |
+ | Input +-+-->+ Digital Gain +---+-->+ Black Level +---+---+
+ +---------+ +--------------+ +--------------+ |
+ +-----------------------------------------------------------------+
+ |
+ | +--------------+ +---------+ +----------------+
+ +-->| Sinter Noise +-+ White +--+--->| Lens Shading +--+---------------+
+ | Reduction | | Balance | | | | | |
+ +--------------+ +---------+ | +----------------+ | |
+ +---> AEXP-0 (A) +--> AEXP-0 (B) |
+ +--------------------------------------------------------------------------+
+ |
+ | +----------------+ +--------------+ +----------------+
+ +-->| Tone mapping +-+--->| Demosaicing +->+ Purple Fringe +-+-----------+
+ | | | +--------------+ | Correction | | |
+ +----------------+ +-> AEXP-IRIDIX +----------------+ +---> AWB-0 |
+ +----------------------------------------------------------------------------+
+ | +-------------+ +-------------+
+ +------------------->| Colour +---+--->| Output |
+ | Correction | | | Pipelines |
+ +-------------+ | +-------------+
+ +--> AWB-1
+
+By default all statistics are drawn from the 0th tap point for each algorithm;
+I.E. AEXP statistics from AEXP-0 (A), AWB statistics from AWB-0 and AF
+statistics from AF-0. This is configurable for AEXP and AWB statsistics through
+programming the ISP's parameters.
+
+.. _mali-c55-3a-params:
+
+Programming ISP Parameters
+==========================
+
+The ISP can be programmed with various parameters from userspace to apply to the
+hardware before and during video stream. This allows userspace to dynamically
+change values such as black level, white balance and lens shading gains and so
+on.
+
+The buffer format and how to populate it are described by the
+:ref:`V4L2_META_FMT_MALI_C55_PARAMS <v4l2-meta-fmt-mali-c55-params>` format,
+which should be set as the data format for the `mali-c55 3a params` video node.

+ by DE=1) and assertion of the VSYNC signal.
+
+ The value is identical to what VIDIOC_QUERY_DV_TIMINGS returns in
+ the vfrontporch field of the v4l2_bt_timings struct.
+
+**frequency_range** (RW)
+ PLL frequency range of the OLDI input clock generator. The PLL frequency is
+ derived from the Pixel Clock Frequency (PCLK) and is equal to PCLK if
+ oldi_lane_width is set to "single" and PCLK/2 if oldi_lane_width is set to
+ "dual".
+
+ | 0 - PLL < 50MHz (default)
+ | 1 - PLL >= 50MHz
+
+ *Note: This parameter can not be changed while the input v4l2 device is
+ open.*
+
+Common FPDL3/GMSL output parameters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**output_id** (R):
+ Output number ID, zero based.
+
+**video_source** (RW):
+ Output video source. If set to 0 or 1, the source is the corresponding card
+ input and the v4l2 output devices are disabled. If set to 2 or 3, the source
+ is the corresponding v4l2 video output device. The default is
+ the corresponding v4l2 output, i.e. 2 for OUT1 and 3 for OUT2.
+
+ | 0 - input 0
+ | 1 - input 1
+ | 2 - v4l2 output 0
+ | 3 - v4l2 output 1
+
+ *Note: This parameter can not be changed while ANY of the input/output v4l2
+ devices is open.*
+
+**display_width** (RW):
+ Display width. There is no autodetection of the connected display, so the
+ proper value must be set before the start of streaming. The default width
+ is 1280.
+
+ *Note: This parameter can not be changed while the output v4l2 device is
+ open.*
+
+**display_height** (RW):
+ Display height. There is no autodetection of the connected display, so the
+ proper value must be set before the start of streaming. The default height
+ is 640.
+
+ *Note: This parameter can not be changed while the output v4l2 device is
+ open.*
+
+**frame_rate** (RW):
+ Output video signal frame rate limit in frames per second. Due to
+ the limited output pixel clock steps, the card can not always generate
+ a frame rate perfectly matching the value required by the connected display.
+ Using this parameter one can limit the frame rate by "crippling" the signal
+ so that the lines are not equal (the porches of the last line differ) but
+ the signal appears like having the exact frame rate to the connected display.
+ The default frame rate limit is 60Hz.
+
+**hsync_polarity** (RW):
+ HSYNC signal polarity.
+
+ | 0 - active low (default)
+ | 1 - active high
+
+**vsync_polarity** (RW):
+ VSYNC signal polarity.
+
+ | 0 - active low (default)
+ | 1 - active high
+
+**de_polarity** (RW):
+ DE signal polarity.
+
+ | 0 - active low
+ | 1 - active high (default)
+
+**pclk_frequency** (RW):
+ Output pixel clock frequency. Allowed values are between 25000-190000(kHz)
+ and there is a non-linear stepping between two consecutive allowed
+ frequencies. The driver finds the nearest allowed frequency to the given
+ value and sets it. When reading this property, you get the exact
+ frequency set by the driver. The default frequency is 61150kHz.
+
+ *Note: This parameter can not be changed while the output v4l2 device is
+ open.*
+
+**hsync_width** (RW):
+ Width of the HSYNC signal in pixels. The default value is 40.
+
+**vsync_width** (RW):
+ Width of the VSYNC signal in video lines. The default value is 20.
+
+**hback_porch** (RW):
+ Number of PCLK pulses between deassertion of the HSYNC signal and the first
+ valid pixel in the video line (marked by DE=1). The default value is 50.
+
+**hfront_porch** (RW):
+ Number of PCLK pulses between the end of the last valid pixel in the video
+ line (marked by DE=1) and assertion of the HSYNC signal. The default value
+ is 50.
+
+**vback_porch** (RW):
+ Number of video lines between deassertion of the VSYNC signal and the video
+ line with the first valid pixel (marked by DE=1). The default value is 31.
+
+**vfront_porch** (RW):
+ Number of video lines between the end of the last valid pixel line (marked
+ by DE=1) and assertion of the VSYNC signal. The default value is 30.
+
+FPDL3 specific input parameters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**fpdl3_input_width** (RW):
+ Number of deserializer input lines.
+
+ | 0 - auto (default)
+ | 1 - single
+ | 2 - dual
+
+FPDL3 specific output parameters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**fpdl3_output_width** (RW):
+ Number of serializer output lines.
+
+ | 0 - auto (default)
+ | 1 - single
+ | 2 - dual
+
+GMSL specific input parameters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**gmsl_mode** (RW):
+ GMSL speed mode.
+
+ | 0 - 12Gb/s (default)
+ | 1 - 6Gb/s
+ | 2 - 3Gb/s
+ | 3 - 1.5Gb/s
+
+**gmsl_stream_id** (RW):
+ The GMSL multi-stream contains up to four video streams. This parameter
+ selects which stream is captured by the video input. The value is the
+ zero-based index of the stream. The default stream id is 0.
+
+ *Note: This parameter can not be changed while the input v4l2 device is
+ open.*
+
+**gmsl_fec** (RW):
+ GMSL Forward Error Correction (FEC).
+
+ | 0 - disabled
+ | 1 - enabled (default)
+
+MTD partitions
+--------------
+
+The mgb4 driver creates a MTD device with two partitions:
+ - mgb4-fw.X - FPGA firmware.
+ - mgb4-data.X - Factory settings, e.g. card serial number.
+
+The *mgb4-fw* partition is writable and is used for FW updates, *mgb4-data* is
+read-only. The *X* attached to the partition name represents the card number.
+Depending on the CONFIG_MTD_PARTITIONED_MASTER kernel configuration, you may
+also have a third partition named *mgb4-flash* available in the system. This
+partition represents the whole, unpartitioned, card's FLASH memory and one should
+not fiddle with it...
+
+IIO (triggers)
+--------------
+
+The mgb4 driver creates an Industrial I/O (IIO) device that provides trigger and
+signal level status capability. The following scan elements are available:
+
+**activity**:
+ The trigger levels and pending status.
+
+ | bit 1 - trigger 1 pending
+ | bit 2 - trigger 2 pending
+ | bit 5 - trigger 1 level
+ | bit 6 - trigger 2 level
+
+**timestamp**:
+ The trigger event timestamp.
+
+The iio device can operate either in "raw" mode where you can fetch the signal
+levels (activity bits 5 and 6) using sysfs access or in triggered buffer mode.
+In the triggered buffer mode you can follow the signal level changes (activity
+bits 1 and 2) using the iio device in /dev. If you enable the timestamps, you
+will also get the exact trigger event time that can be matched to a video frame
+(every mgb4 video frame has a timestamp with the same clock source).
+
+*Note: although the activity sample always contains all the status bits, it makes
+no sense to get the pending bits in raw mode or the level bits in the triggered
+buffer mode - the values do not represent valid data in such case.*

-Introduction
-------------
-
-The OMAP44XX family of chips contains the Imaging SubSystem (a.k.a. ISS),
-Which contains several components that can be categorized in 3 big groups:
-
-- Interfaces (2 Interfaces: CSI2-A & CSI2-B/CCP2)
-- ISP (Image Signal Processor)
-- SIMCOP (Still Image Coprocessor)
-
-For more information, please look in [#f1]_ for latest version of:
-"OMAP4430 Multimedia Device Silicon Revision 2.x"
-
-As of Revision AB, the ISS is described in detail in section 8.
-
-This driver is supporting **only** the CSI2-A/B interfaces for now.
-
-It makes use of the Media Controller framework [#f2]_, and inherited most of the
-code from OMAP3 ISP driver (found under drivers/media/platform/ti/omap3isp/\*),
-except that it doesn't need an IOMMU now for ISS buffers memory mapping.
-
-Supports usage of MMAP buffers only (for now).
-
-Tested platforms
-----------------
-
-- OMAP4430SDP, w/ ES2.1 GP & SEVM4430-CAM-V1-0 (Contains IMX060 & OV5640, in
- which only the last one is supported, outputting YUV422 frames).
-
-- TI Blaze MDP, w/ OMAP4430 ES2.2 EMU (Contains 1 IMX060 & 2 OV5650 sensors, in
- which only the OV5650 are supported, outputting RAW10 frames).
-

+=========================================================
+Raspberry Pi PiSP Back End Memory-to-Memory ISP (pisp-be)
+=========================================================
+
+The PiSP Back End
+=================
+
+The PiSP Back End is a memory-to-memory Image Signal Processor (ISP) which reads
+image data from DRAM memory and performs image processing as specified by the
+application through the parameters in a configuration buffer, before writing
+pixel data back to memory through two distinct output channels.
+
+The ISP registers and programming model are documented in the `Raspberry Pi
+Image Signal Processor (PiSP) Specification document`_
+
+The PiSP Back End ISP processes images in tiles. The handling of image
+tessellation and the computation of low-level configuration parameters is
+realized by a free software library called `libpisp
+<https://github.com/raspberrypi/libpisp>`_.
+
+The full image processing pipeline, which involves capturing RAW Bayer data from
+an image sensor through a MIPI CSI-2 compatible capture interface, storing them
+in DRAM memory and processing them in the PiSP Back End to obtain images usable
+by an application is implemented in `libcamera <https://libcamera.org>`_ as
+part of the Raspberry Pi platform support.
+
+The pisp-be driver
+==================
+
+The Raspberry Pi PiSP Back End (pisp-be) driver is located under
+drivers/media/platform/raspberrypi/pisp-be. It uses the `V4L2 API` to register
+a number of video capture and output devices, the `V4L2 subdev API` to register
+a subdevice for the ISP that connects the video devices in a single media graph
+realized using the `Media Controller (MC) API`.
+
+The media topology registered by the `pisp-be` driver is represented below:
+
+.. _pips-be-topology:
+
+.. kernel-figure:: raspberrypi-pisp-be.dot
+ :alt: Diagram of the default media pipeline topology
+ :align: center
+
+
+The media graph registers the following video device nodes:
+
+- pispbe-input: output device for images to be submitted to the ISP for
+ processing.
+- pispbe-tdn_input: output device for temporal denoise.
+- pispbe-stitch_input: output device for image stitching (HDR).
+- pispbe-output0: first capture device for processed images.
+- pispbe-output1: second capture device for processed images.
+- pispbe-tdn_output: capture device for temporal denoise.
+- pispbe-stitch_output: capture device for image stitching (HDR).
+- pispbe-config: output device for ISP configuration parameters.
+
+pispbe-input
+------------
+
+Images to be processed by the ISP are queued to the `pispbe-input` output device
+node. For a list of image formats supported as input to the ISP refer to the
+`Raspberry Pi Image Signal Processor (PiSP) Specification document`_.
+
+pispbe-tdn_input, pispbe-tdn_output
+-----------------------------------
+
+The `pispbe-tdn_input` output video device receives images to be processed by
+the temporal denoise block which are captured from the `pispbe-tdn_output`
+capture video device. Userspace is responsible for maintaining queues on both
+devices, and ensuring that buffers completed on the output are queued to the
+input.
+
+pispbe-stitch_input, pispbe-stitch_output
+-----------------------------------------
+
+To realize HDR (high dynamic range) image processing the image stitching and
+tonemapping blocks are used. The `pispbe-stitch_output` writes images to memory
+and the `pispbe-stitch_input` receives the previously written frame to process
+it along with the current input image. Userspace is responsible for maintaining
+queues on both devices, and ensuring that buffers completed on the output are
+queued to the input.
+
+pispbe-output0, pispbe-output1
+------------------------------
+
+The two capture devices write to memory the pixel data as processed by the ISP.
+
+pispbe-config
+-------------
+
+The `pispbe-config` output video devices receives a buffer of configuration
+parameters that define the desired image processing to be performed by the ISP.
+
+The format of the ISP configuration parameter is defined by
+:c:type:`pisp_be_tiles_config` C structure and the meaning of each parameter is
+described in the `Raspberry Pi Image Signal Processor (PiSP) Specification
+document`_.
+
+ISP configuration
+=================
+
+The ISP configuration is described solely by the content of the parameters
+buffer. The only parameter that userspace needs to configure using the V4L2 API
+is the image format on the output and capture video devices for validation of
+the content of the parameters buffer.

+============================================
+
+The PiSP Camera Front End
+=========================
+
+The PiSP Camera Front End (CFE) is a module which combines a CSI-2 receiver with
+a simple ISP, called the Front End (FE).
+
+The CFE has four DMA engines and can write frames from four separate streams
+received from the CSI-2 to the memory. One of those streams can also be routed
+directly to the FE, which can do minimal image processing, write two versions
+(e.g. non-scaled and downscaled versions) of the received frames to memory and
+provide statistics of the received frames.
+
+The FE registers are documented in the `Raspberry Pi Image Signal Processor
+(ISP) Specification document
+<https://datasheets.raspberrypi.com/camera/raspberry-pi-image-signal-processor-specification.pdf>`_,
+and example code for FE can be found in `libpisp
+<https://github.com/raspberrypi/libpisp>`_.
+
+The rp1-cfe driver
+==================
+
+The Raspberry Pi PiSP Camera Front End (rp1-cfe) driver is located under
+drivers/media/platform/raspberrypi/rp1-cfe. It uses the `V4L2 API` to register
+a number of video capture and output devices, the `V4L2 subdev API` to register
+subdevices for the CSI-2 received and the FE that connects the video devices in
+a single media graph realized using the `Media Controller (MC) API`.
+
+The media topology registered by the `rp1-cfe` driver, in this particular
+example connected to an imx219 sensor, is the following one:
+
+.. _rp1-cfe-topology:
+
+.. kernel-figure:: raspberrypi-rp1-cfe.dot
+ :alt: Diagram of an example media pipeline topology
+ :align: center
+
+The media graph contains the following video device nodes:
+
+- rp1-cfe-csi2-ch0: capture device for the first CSI-2 stream
+- rp1-cfe-csi2-ch1: capture device for the second CSI-2 stream
+- rp1-cfe-csi2-ch2: capture device for the third CSI-2 stream
+- rp1-cfe-csi2-ch3: capture device for the fourth CSI-2 stream
+- rp1-cfe-fe-image0: capture device for the first FE output
+- rp1-cfe-fe-image1: capture device for the second FE output
+- rp1-cfe-fe-stats: capture device for the FE statistics
+- rp1-cfe-fe-config: output device for FE configuration
+
+rp1-cfe-csi2-chX
+----------------
+
+The rp1-cfe-csi2-chX capture devices are normal V4L2 capture devices which
+can be used to capture video frames or metadata received from the CSI-2.
+

+Rockchip Camera Interface (CIF)
+=========================================
+
+Introduction
+============
+
+The Rockchip Camera Interface (CIF) is featured in many Rockchip SoCs in
+different variants.
+The different variants are combinations of common building blocks, such as
+
+* INTERFACE blocks of different types, namely
+
+ * the Digital Video Port (DVP, a parallel data interface)
+ * the interface block for the MIPI CSI-2 receiver
+
+* CROP units
+
+* MIPI CSI-2 receiver (not available on all variants): This unit is referred
+ to as MIPI CSI HOST in the Rockchip documentation.
+ Technically, it is a separate hardware block, but it is strongly coupled to
+ the CIF and therefore included here.
+
+* MUX units (not available on all variants) that pass the video data to an
+ image signal processor (ISP)
+
+* SCALE units (not available on all variants)
+
+* DMA engines that transfer video data into system memory using a
+ double-buffering mechanism called ping-pong mode
+
+* Support for four streams per INTERFACE block (not available on all
+ variants), e.g., for MIPI CSI-2 Virtual Channels (VCs)
+
+This document describes the different variants of the CIF, their hardware
+layout, as well as their representation in the media controller centric rkcif
+device driver, which is located under drivers/media/platform/rockchip/rkcif.
+
+Variants
+========
+
+Rockchip PX30 Video Input Processor (VIP)
+-----------------------------------------
+
+The PX30 Video Input Processor (VIP) features a digital video port that accepts
+parallel video data or BT.656.
+Since these protocols do not feature multiple streams, the VIP has one DMA
+engine that transfers the input video data into system memory.
+
+The rkcif driver represents this hardware variant by exposing one V4L2 subdevice
+(the DVP INTERFACE/CROP block) and one V4L2 device (the DVP DMA engine).
+
+Rockchip RK3568 Video Capture (VICAP)
+-------------------------------------
+
+The RK3568 Video Capture (VICAP) unit features a digital video port and a MIPI
+CSI-2 receiver that can receive video data independently.
+The DVP accepts parallel video data, BT.656 and BT.1120.
+Since the BT.1120 protocol may feature more than one stream, the RK3568 VICAP
+DVP features four DMA engines that can capture different streams.
+Similarly, the RK3568 VICAP MIPI CSI-2 receiver features four DMA engines to
+handle different Virtual Channels (VCs).
+
+The rkcif driver represents this hardware variant by exposing up the following
+V4L2 subdevices:
+
+* rkcif-dvp0: INTERFACE/CROP block for the DVP
+
+and the following video devices:
+
+* rkcif-dvp0-id0: The support for multiple streams on the DVP is not yet
+ implemented, as it is hard to find test hardware. Thus, this video device
+ represents the first DMA engine of the RK3568 DVP.

-Capture Overlay
----------------
-
-Note: capture overlay support is implemented primarily to test the existing
-V4L2 capture overlay API. In practice few if any GPUs support such overlays
-anymore, and neither are they generally needed anymore since modern hardware
-is so much more capable. By setting flag 0x10000 in the node_types module
-option the vivid driver will create a simple framebuffer device that can be
-used for testing this API. Whether this API should be used for new drivers is
-questionable.
-
-This driver has support for a destructive capture overlay with bitmap clipping
-and list clipping (up to 16 rectangles) capabilities. Overlays are not
-supported for multiplanar formats. It also honors the struct v4l2_window field
-setting: if it is set to FIELD_TOP or FIELD_BOTTOM and the capture setting is
-FIELD_ALTERNATE, then only the top or bottom fields will be copied to the overlay.
-
-The overlay only works if you are also capturing at that same time. This is a
-vivid limitation since it copies from a buffer to the overlay instead of
-filling the overlay directly. And if you are not capturing, then no buffers
-are available to fill.
-
-In addition, the pixelformat of the capture format and that of the framebuffer
-must be the same for the overlay to work. Otherwise VIDIOC_OVERLAY will return
-an error.
-
-In order to really see what it going on you will need to create two vivid
-instances: the first with a framebuffer enabled. You configure the capture
-overlay of the second instance to use the framebuffer of the first, then
-you start capturing in the second instance. For the first instance you setup
-the output overlay for the video output, turn on video looping and capture
-to see the blended framebuffer overlay that's being written to by the second
-instance. This setup would require the following commands:

+Data Access Monitoring Results Stat
+===================================
+
+Data Access Monitoring Results Stat (DAMON_STAT) is a static kernel module that
+is aimed to be used for simple access pattern monitoring. It monitors accesses
+on the system's entire physical memory using DAMON, and provides simplified
+access monitoring results statistics, namely idle time percentiles and
+estimated memory bandwidth.
+
+.. _damon_stat_monitoring_accuracy_overhead:
+
+Monitoring Accuracy and Overhead
+================================
+
+DAMON_STAT uses monitoring intervals :ref:`auto-tuning
+<damon_design_monitoring_intervals_autotuning>` to make its accuracy high and
+overhead minimum. It auto-tunes the intervals aiming 4 % of observable access
+events to be captured in each snapshot, while limiting the resulting sampling
+interval to be 5 milliseconds in minimum and 10 seconds in maximum. On a few
+production server systems, it resulted in consuming only 0.x % single CPU time,
+while capturing reasonable quality of access patterns. The tuning-resulting
+intervals can be retrieved via ``aggr_interval_us`` :ref:`parameter
+<damon_stat_aggr_interval_us>`.
+
+Interface: Module Parameters
+============================
+
+To use this feature, you should first ensure your system is running on a kernel
+that is built with ``CONFIG_DAMON_STAT=y``. The feature can be enabled by
+default at build time, by setting ``CONFIG_DAMON_STAT_ENABLED_DEFAULT`` true.
+
+To let sysadmins enable or disable it at boot and/or runtime, and read the
+monitoring results, DAMON_STAT provides module parameters. Following
+sections are descriptions of the parameters.
+
+enabled
+-------
+
+Enable or disable DAMON_STAT.
+
+You can enable DAMON_STAT by setting the value of this parameter as ``Y``.
+Setting it as ``N`` disables DAMON_STAT. The default value is set by
+``CONFIG_DAMON_STAT_ENABLED_DEFAULT`` build config option.
+
+.. _damon_stat_aggr_interval_us:
+
+aggr_interval_us
+----------------
+
+Auto-tuned aggregation time interval in microseconds.
+
+Users can read the aggregation interval of DAMON that is being used by the
+DAMON instance for DAMON_STAT. It is :ref:`auto-tuned
+<damon_stat_monitoring_accuracy_overhead>` and therefore the value is
+dynamically changed.
+
+estimated_memory_bandwidth
+--------------------------
+
+Estimated memory bandwidth consumption (bytes per second) of the system.
+
+DAMON_STAT reads observed access events on the current DAMON results snapshot
+and converts it to memory bandwidth consumption estimation in bytes per second.
+The resulting metric is exposed to user via this read-only parameter. Because
+DAMON uses sampling, this is only an estimation of the access intensity rather
+than accurate memory bandwidth.
+
+memory_idle_ms_percentiles
+--------------------------
+
+Per-byte idle time (milliseconds) percentiles of the system.
+
+DAMON_STAT calculates how long each byte of the memory was not accessed until
+now (idle time), based on the current DAMON results snapshot. For regions
+having access frequency (nr_accesses) larger than zero, how long the current
+access frequency level was kept multiplied by ``-1`` becomes the idlee time of
+every byte of the region. If a region has zero access frequency (nr_accesses),
+how long the region was keeping the zero access frequency (age) becomes the
+idle time of every byte of the region. Then, DAMON_STAT exposes the
+percentiles of the idle time values via this read-only parameter. Reading the
+parameter returns 101 idle time values in milliseconds, separated by comma.
+Each value represents 0-th, 1st, 2nd, 3rd, ..., 99th and 100th percentile idle
+times.

+In the beginning, the directory has only one file, ``nr_filters``. Writing a
number (``N``) to the file creates the number of child directories named ``0``
to ``N-1``. Each directory represents each filter. The filters are evaluated
in the numeric order.
-Each filter directory contains three files, namely ``type``, ``matcing``, and
-``memcg_path``. You can write one of two special keywords, ``anon`` for
-anonymous pages, or ``memcg`` for specific memory cgroup filtering. In case of
-the memory cgroup filtering, you can specify the memory cgroup of the interest
-by writing the path of the memory cgroup from the cgroups mount point to
-``memcg_path`` file. You can write ``Y`` or ``N`` to ``matching`` file to
-filter out pages that does or does not match to the type, respectively. Then,
-the scheme's action will not be applied to the pages that specified to be
-filtered out.
+Each filter directory contains nine files, namely ``type``, ``matching``,
+``allow``, ``memcg_path``, ``addr_start``, ``addr_end``, ``min``, ``max``
+and ``target_idx``. To ``type`` file, you can write the type of the filter.
+Refer to :ref:`the design doc <damon_design_damos_filters>` for available type
+names, their meaning and on what layer those are handled.
+
+For ``memcg`` type, you can specify the memory cgroup of the interest by
+writing the path of the memory cgroup from the cgroups mount point to
+``memcg_path`` file. For ``addr`` type, you can specify the start and end
+address of the range (open-ended interval) to ``addr_start`` and ``addr_end``
+files, respectively. For ``hugepage_size`` type, you can specify the minimum
+and maximum size of the range (closed interval) to ``min`` and ``max`` files,
+respectively. For ``target`` type, you can specify the index of the target
+between the list of the DAMON context's monitoring targets list to
+``target_idx`` file.
+
+You can write ``Y`` or ``N`` to ``matching`` file to specify whether the filter
+is for memory that matches the ``type``. You can write ``Y`` or ``N`` to
+``allow`` file to specify if applying the action to the memory that satisfies
+the ``type`` and ``matching`` should be allowed or not.
For example, below restricts a DAMOS action to be applied to only non-anonymous
pages of all memory cgroups except ``/having_care_already``.::
+ # cd ops_filters/0/
# echo 2 > nr_filters
- # # filter out anonymous pages
+ # # disallow anonymous pages
echo anon > 0/type
echo Y > 0/matching
+ echo N > 0/allow
# # further filter out all cgroups except one at '/having_care_already'
echo memcg > 1/type
echo /having_care_already > 1/memcg_path
- echo N > 1/matching
+ echo Y > 1/matching
+ echo N > 1/allow
+
+Refer to the :ref:`DAMOS filters design documentation

+Directory for specifying the destinations of given DAMON-based operation
+scheme's action. This directory is ignored if the action of the given scheme
+is not supporting multiple destinations. Only ``DAMOS_MIGRATE_{HOT,COLD}``
+actions are supporting multiple destinations.
+
+In the beginning, the directory has only one file, ``nr_dests``. Writing a
+number (``N``) to the file creates the number of child directories named ``0``
+to ``N-1``. Each directory represents each action destination.
+
+Each destination directory contains two files, namely ``id`` and ``weight``.
+Users can write and read the identifier of the destination to ``id`` file.
+For ``DAMOS_MIGRATE_{HOT,COLD}`` actions, the migrate destination node's node
+id should be written to ``id`` file. Users can write and read the weight of
+the destination among the given destinations to the ``weight`` file. The
+weight can be an arbitrary integer. When DAMOS apply the action to each entity
+of the memory region, it will select the destination of the action based on the
+relative weights of the destinations.

When a special keyword, ``update_schemes_tried_regions``, is written to the
-relevant ``kdamonds/<N>/state`` file, DAMON creates directories named integer
-starting from ``0`` under this directory. Each directory contains files
-exposing detailed information about each of the memory region that the
-corresponding scheme's ``action`` has tried to be applied under this directory,
-during next :ref:`aggregation interval <sysfs_monitoring_attrs>`. The
-information includes address range, ``nr_accesses``, , and ``age`` of the
-region.
+relevant ``kdamonds/<N>/state`` file, DAMON updates the ``total_bytes`` file so
+that reading it returns the total size of the scheme tried regions, and creates
+directories named integer starting from ``0`` under this directory. Each
+directory contains files exposing detailed information about each of the memory
+region that the corresponding scheme's ``action`` has tried to be applied under
+this directory, during next :ref:`apply interval <damon_design_damos>` of the
+corresponding scheme. The information includes address range, ``nr_accesses``,
+and ``age`` of the region.
+
+Writing ``update_schemes_tried_bytes`` to the relevant ``kdamonds/<N>/state``
+file will only update the ``total_bytes`` file, and will not create the
+subdirectories.
The directories will be removed when another special keyword,
``clear_schemes_tried_regions``, is written to the relevant
``kdamonds/<N>/state`` file.
+The expected usage of this directory is investigations of schemes' behaviors,
+and query-like efficient data access monitoring results retrievals. For the
+latter use case, in particular, users can set the ``action`` as ``stat`` and
+set the ``access pattern`` as their interested pattern that they want to query.
+
+.. _sysfs_schemes_tried_region:
+

------------------
-In each region directory, you will find four files (``start``, ``end``,
-``nr_accesses``, and ``age``). Reading the files will show the start and end
-addresses, ``nr_accesses``, and ``age`` of the region that corresponding
-DAMON-based operation scheme ``action`` has tried to be applied.

-
-debugfs Interface (DEPRECATED!)
-===============================
-
-.. note::
-
- THIS IS DEPRECATED!
-
- DAMON debugfs interface is deprecated, so users should move to the
- :ref:`sysfs interface <sysfs_interface>`. If you depend on this and cannot
- move, please report your usecase to damon@lists.linux.dev and
- linux-mm@kvack.org.
-
-DAMON exports eight files, ``attrs``, ``target_ids``, ``init_regions``,
-``schemes``, ``monitor_on``, ``kdamond_pid``, ``mk_contexts`` and
-``rm_contexts`` under its debugfs directory, ``<debugfs>/damon/``.
-
-
-Attributes
-----------
-
-Users can get and set the ``sampling interval``, ``aggregation interval``,
-``update interval``, and min/max number of monitoring target regions by
-reading from and writing to the ``attrs`` file. To know about the monitoring
-attributes in detail, please refer to the :doc:`/mm/damon/design`. For
-example, below commands set those values to 5 ms, 100 ms, 1,000 ms, 10 and
-1000, and then check it again::
-
- # cd <debugfs>/damon
- # echo 5000 100000 1000000 10 1000 > attrs
- # cat attrs
- 5000 100000 1000000 10 1000
-
-
-Target IDs
-----------
-
-Some types of address spaces supports multiple monitoring target. For example,
-the virtual memory address spaces monitoring can have multiple processes as the
-monitoring targets. Users can set the targets by writing relevant id values of
-the targets to, and get the ids of the current targets by reading from the
-``target_ids`` file. In case of the virtual address spaces monitoring, the
-values should be pids of the monitoring target processes. For example, below
-commands set processes having pids 42 and 4242 as the monitoring targets and
-check it again::
-
- # cd <debugfs>/damon
- # echo 42 4242 > target_ids
- # cat target_ids
- 42 4242
-
-Users can also monitor the physical memory address space of the system by
-writing a special keyword, "``paddr\n``" to the file. Because physical address
-space monitoring doesn't support multiple targets, reading the file will show a
-fake value, ``42``, as below::
-
- # cd <debugfs>/damon
- # echo paddr > target_ids
- # cat target_ids
- 42
-
-Note that setting the target ids doesn't start the monitoring.
-
-
-Initial Monitoring Target Regions
----------------------------------
-
-In case of the virtual address space monitoring, DAMON automatically sets and
-updates the monitoring target regions so that entire memory mappings of target
-processes can be covered. However, users can want to limit the monitoring
-region to specific address ranges, such as the heap, the stack, or specific
-file-mapped area. Or, some users can know the initial access pattern of their
-workloads and therefore want to set optimal initial regions for the 'adaptive
-regions adjustment'.
-
-In contrast, DAMON do not automatically sets and updates the monitoring target
-regions in case of physical memory monitoring. Therefore, users should set the
-monitoring target regions by themselves.
-
-In such cases, users can explicitly set the initial monitoring target regions
-as they want, by writing proper values to the ``init_regions`` file. The input
-should be a sequence of three integers separated by white spaces that represent
-one region in below form.::
-
- <target idx> <start address> <end address>
-
-The ``target idx`` should be the index of the target in ``target_ids`` file,
-starting from ``0``, and the regions should be passed in address order. For
-example, below commands will set a couple of address ranges, ``1-100`` and
-``100-200`` as the initial monitoring target region of pid 42, which is the
-first one (index ``0``) in ``target_ids``, and another couple of address
-ranges, ``20-40`` and ``50-100`` as that of pid 4242, which is the second one
-(index ``1``) in ``target_ids``.::
-
- # cd <debugfs>/damon
- # cat target_ids
- 42 4242
- # echo "0 1 100 \
- 0 100 200 \
- 1 20 40 \
- 1 50 100" > init_regions
-
-Note that this sets the initial monitoring target regions only. In case of
-virtual memory monitoring, DAMON will automatically updates the boundary of the
-regions after one ``update interval``. Therefore, users should set the
-``update interval`` large enough in this case, if they don't want the
-update.
-
-
-Schemes
--------
-
-For usual DAMON-based data access aware memory management optimizations, users
-would simply want the system to apply a memory management action to a memory
-region of a specific access pattern. DAMON receives such formalized operation
-schemes from the user and applies those to the target processes.
-
-Users can get and set the schemes by reading from and writing to ``schemes``
-debugfs file. Reading the file also shows the statistics of each scheme. To
-the file, each of the schemes should be represented in each line in below
-form::
-
- <target access pattern> <action> <quota> <watermarks>
-
-You can disable schemes by simply writing an empty string to the file.
-
-Target Access Pattern
-~~~~~~~~~~~~~~~~~~~~~
-
-The ``<target access pattern>`` is constructed with three ranges in below
-form::
-
- min-size max-size min-acc max-acc min-age max-age
-
-Specifically, bytes for the size of regions (``min-size`` and ``max-size``),
-number of monitored accesses per aggregate interval for access frequency
-(``min-acc`` and ``max-acc``), number of aggregate intervals for the age of
-regions (``min-age`` and ``max-age``) are specified. Note that the ranges are
-closed interval.
-
-Action
-~~~~~~
-
-The ``<action>`` is a predefined integer for memory management actions, which
-DAMON will apply to the regions having the target access pattern. The
-supported numbers and their meanings are as below.
-
- - 0: Call ``madvise()`` for the region with ``MADV_WILLNEED``. Ignored if
- ``target`` is ``paddr``.
- - 1: Call ``madvise()`` for the region with ``MADV_COLD``. Ignored if
- ``target`` is ``paddr``.
- - 2: Call ``madvise()`` for the region with ``MADV_PAGEOUT``.
- - 3: Call ``madvise()`` for the region with ``MADV_HUGEPAGE``. Ignored if
- ``target`` is ``paddr``.
- - 4: Call ``madvise()`` for the region with ``MADV_NOHUGEPAGE``. Ignored if
- ``target`` is ``paddr``.
- - 5: Do nothing but count the statistics
-
-Quota
-~~~~~
-
-Optimal ``target access pattern`` for each ``action`` is workload dependent, so
-not easy to find. Worse yet, setting a scheme of some action too aggressive
-can cause severe overhead. To avoid such overhead, users can limit time and
-size quota for the scheme via the ``<quota>`` in below form::
-
- <ms> <sz> <reset interval> <priority weights>
-
-This makes DAMON to try to use only up to ``<ms>`` milliseconds for applying
-the action to memory regions of the ``target access pattern`` within the
-``<reset interval>`` milliseconds, and to apply the action to only up to
-``<sz>`` bytes of memory regions within the ``<reset interval>``. Setting both
-``<ms>`` and ``<sz>`` zero disables the quota limits.
-
-When the quota limit is expected to be exceeded, DAMON prioritizes found memory
-regions of the ``target access pattern`` based on their size, access frequency,
-and age. For personalized prioritization, users can set the weights for the
-three properties in ``<priority weights>`` in below form::
-
- <size weight> <access frequency weight> <age weight>
-
-Watermarks
-~~~~~~~~~~
-
-Some schemes would need to run based on current value of the system's specific
-metrics like free memory ratio. For such cases, users can specify watermarks
-for the condition.::
-
- <metric> <check interval> <high mark> <middle mark> <low mark>
-
-``<metric>`` is a predefined integer for the metric to be checked. The
-supported numbers and their meanings are as below.
-
- - 0: Ignore the watermarks
- - 1: System's free memory rate (per thousand)
-
-The value of the metric is checked every ``<check interval>`` microseconds.
-
-If the value is higher than ``<high mark>`` or lower than ``<low mark>``, the
-scheme is deactivated. If the value is lower than ``<mid mark>``, the scheme
-is activated.
-
-.. _damos_stats:
-
-Statistics
-~~~~~~~~~~
-
-It also counts the total number and bytes of regions that each scheme is tried
-to be applied, the two numbers for the regions that each scheme is successfully
-applied, and the total number of the quota limit exceeds. This statistics can
-be used for online analysis or tuning of the schemes.
-
-The statistics can be shown by reading the ``schemes`` file. Reading the file
-will show each scheme you entered in each line, and the five numbers for the
-statistics will be added at the end of each line.
-
-Example
-~~~~~~~
-
-Below commands applies a scheme saying "If a memory region of size in [4KiB,
-8KiB] is showing accesses per aggregate interval in [0, 5] for aggregate
-interval in [10, 20], page out the region. For the paging out, use only up to
-10ms per second, and also don't page out more than 1GiB per second. Under the
-limitation, page out memory regions having longer age first. Also, check the
-free memory rate of the system every 5 seconds, start the monitoring and paging
-out when the free memory rate becomes lower than 50%, but stop it if the free
-memory rate becomes larger than 60%, or lower than 30%".::
-
- # cd <debugfs>/damon
- # scheme="4096 8192 0 5 10 20 2" # target access pattern and action
- # scheme+=" 10 $((1024*1024*1024)) 1000" # quotas
- # scheme+=" 0 0 100" # prioritization weights
- # scheme+=" 1 5000000 600 500 300" # watermarks
- # echo "$scheme" > schemes
-
-
-Turning On/Off
---------------
-
-Setting the files as described above doesn't incur effect unless you explicitly
-start the monitoring. You can start, stop, and check the current status of the
-monitoring by writing to and reading from the ``monitor_on`` file. Writing
-``on`` to the file starts the monitoring of the targets with the attributes.
-Writing ``off`` to the file stops those. DAMON also stops if every target
-process is terminated. Below example commands turn on, off, and check the
-status of DAMON::
-
- # cd <debugfs>/damon
- # echo on > monitor_on
- # echo off > monitor_on
- # cat monitor_on
- off
-
-Please note that you cannot write to the above-mentioned debugfs files while
-the monitoring is turned on. If you write to the files while DAMON is running,
-an error code such as ``-EBUSY`` will be returned.
-
-
-Monitoring Thread PID
----------------------
-
-DAMON does requested monitoring with a kernel thread called ``kdamond``. You
-can get the pid of the thread by reading the ``kdamond_pid`` file. When the
-monitoring is turned off, reading the file returns ``none``. ::
-
- # cd <debugfs>/damon
- # cat monitor_on
- off
- # cat kdamond_pid
- none
- # echo on > monitor_on
- # cat kdamond_pid
- 18594
-
-
-Using Multiple Monitoring Threads
----------------------------------
-
-One ``kdamond`` thread is created for each monitoring context. You can create
-and remove monitoring contexts for multiple ``kdamond`` required use case using
-the ``mk_contexts`` and ``rm_contexts`` files.
-
-Writing the name of the new context to the ``mk_contexts`` file creates a
-directory of the name on the DAMON debugfs directory. The directory will have
-DAMON debugfs files for the context. ::
-
- # cd <debugfs>/damon
- # ls foo
- # ls: cannot access 'foo': No such file or directory
- # echo foo > mk_contexts
- # ls foo
- # attrs init_regions kdamond_pid schemes target_ids
-
-If the context is not needed anymore, you can remove it and the corresponding
-directory by putting the name of the context to the ``rm_contexts`` file. ::
-
- # echo foo > rm_contexts
- # ls foo
- # ls: cannot access 'foo': No such file or directory
-
-Note that ``mk_contexts``, ``rm_contexts``, and ``monitor_on`` files are in the
-root directory only.
-
-
.. _tracepoint:
-Tracepoint for Monitoring Results
-=================================
+Tracepoints for Monitoring Results
+==================================
+
+Users can get the monitoring results via the :ref:`tried_regions
+<sysfs_schemes_tried_regions>`. The interface is useful for getting a
+snapshot, but it could be inefficient for fully recording all the monitoring
+results. For the purpose, two trace points, namely ``damon:damon_aggregated``
+and ``damon:damos_before_apply``, are provided. ``damon:damon_aggregated``
+provides the whole monitoring results, while ``damon:damos_before_apply``
+provides the monitoring results for regions that each DAMON-based Operation
+Scheme (:ref:`DAMOS <damon_design_damos>`) is gonna be applied. Hence,
+``damon:damos_before_apply`` is more useful for recording internal behavior of
+DAMOS, or DAMOS target access
+:ref:`pattern <damon_design_damos_access_pattern>` based query-like efficient
+monitoring results recording.
+
+While the monitoring is turned on, you could record the tracepoint events and
+show results using tracepoint supporting tools like ``perf``. For example::
-DAMON provides the monitoring results via a tracepoint,
-``damon:damon_aggregated``. While the monitoring is turned on, you could
-record the tracepoint events and show results using tracepoint supporting tools
-like ``perf``. For example::
-
- # echo on > monitor_on
+ # echo on > kdamonds/0/state
# perf record -e damon:damon_aggregated &
# sleep 5
# kill 9 $(pidof perf)
- # echo off > monitor_on
+ # echo off > kdamonds/0/state
# perf script
+ kdamond.0 46568 [027] 79357.842179: damon:damon_aggregated: target_id=0 nr_regions=11 122509119488-135708762112: 0 864
+ [...]
+
+Each line of the perf script output represents each monitoring region. The
+first five fields are as usual other tracepoint outputs. The sixth field
+(``target_id=X``) shows the ide of the monitoring target of the region. The
+seventh field (``nr_regions=X``) shows the total number of monitoring regions
+for the target. The eighth field (``X-Y:``) shows the start (``X``) and end
+(``Y``) addresses of the region in bytes. The ninth field (``X``) shows the
+``nr_accesses`` of the region (refer to
+:ref:`design <damon_design_region_based_sampling>` for more details of the
+counter). Finally the tenth field (``X``) shows the ``age`` of the region
+(refer to :ref:`design <damon_design_age_tracking>` for more details of the
+counter).
+
+If the event was ``damon:damos_beofre_apply``, the ``perf script`` output would
+be somewhat like below::
+
+ kdamond.0 47293 [000] 80801.060214: damon:damos_before_apply: ctx_idx=0 scheme_idx=0 target_idx=0 nr_regions=11 121932607488-135128711168: 0 136
+ [...]
+
+Each line of the output represents each monitoring region that each DAMON-based
+Operation Scheme was about to be applied at the traced time. The first five
+fields are as usual. It shows the index of the DAMON context (``ctx_idx=X``)
+of the scheme in the list of the contexts of the context's kdamond, the index
+of the scheme (``scheme_idx=X``) in the list of the schemes of the context, in
+addition to the output of ``damon_aggregated`` tracepoint.

+:ref:`concepts <kho-concepts>`. If you have not read
+them yet, please do so now.
+
+Prerequisites
+=============
+
+KHO is available when the kernel is compiled with ``CONFIG_KEXEC_HANDOVER``
+set to y. Every KHO producer may have its own config option that you
+need to enable if you would like to preserve their respective state across
+kexec.
+
+To use KHO, please boot the kernel with the ``kho=on`` command line
+parameter. You may use ``kho_scratch`` parameter to define size of the
+scratch regions. For example ``kho_scratch=16M,512M,256M`` will reserve a
+16 MiB low memory scratch area, a 512 MiB global scratch region, and 256 MiB
+per NUMA node scratch regions on boot.
+
+Perform a KHO kexec
+===================
+
+First, before you perform a KHO kexec, you need to move the system into
+the :ref:`KHO finalization phase <kho-finalization-phase>` ::
+
+ $ echo 1 > /sys/kernel/debug/kho/out/finalize
+
+After this command, the KHO FDT is available in
+``/sys/kernel/debug/kho/out/fdt``. Other subsystems may also register
+their own preserved sub FDTs under
+``/sys/kernel/debug/kho/out/sub_fdts/``.
+
+Next, load the target payload and kexec into it. It is important that you
+use the ``-s`` parameter to use the in-kernel kexec file loader, as user
+space kexec tooling currently has no support for KHO with the user space
+based file loader ::
+
+ # kexec -l /path/to/bzImage --initrd /path/to/initrd -s
+ # kexec -e
+
+The new kernel will boot up and contain some of the previous kernel's state.
+
+For example, if you used ``reserve_mem`` command line parameter to create
+an early memory reservation, the new kernel will have that memory at the
+same physical address as the old kernel.
+
+Abort a KHO exec
+================
+
+You can move the system out of KHO finalization phase again by calling ::
+
+ $ echo 0 > /sys/kernel/debug/kho/out/active
+
+After this command, the KHO FDT is no longer available in
+``/sys/kernel/debug/kho/out/fdt``.
+
+debugfs Interfaces
+==================
+
+Currently KHO creates the following debugfs interfaces. Notice that these
+interfaces may change in the future. They will be moved to sysfs once KHO is
+stabilized.
+
+``/sys/kernel/debug/kho/out/finalize``
+ Kexec HandOver (KHO) allows Linux to transition the state of
+ compatible drivers into the next kexec'ed kernel. To do so,
+ device drivers will instruct KHO to preserve memory regions,
+ which could contain serialized kernel state.
+ While the state is serialized, they are unable to perform
+ any modifications to state that was serialized, such as
+ handed over memory allocations.
+
+ When this file contains "1", the system is in the transition
+ state. When contains "0", it is not. To switch between the
+ two states, echo the respective number into this file.
+
+``/sys/kernel/debug/kho/out/fdt``
+ When KHO state tree is finalized, the kernel exposes the
+ flattened device tree blob that carries its current KHO
+ state in this file. Kexec user space tooling can use this
+ as input file for the KHO payload image.
+
+``/sys/kernel/debug/kho/out/scratch_len``
+ Lengths of KHO scratch regions, which are physically contiguous
+ memory regions that will always stay available for future kexec
+ allocations. Kexec user space tools can use this file to determine
+ where it should place its payload images.
+
+``/sys/kernel/debug/kho/out/scratch_phys``
+ Physical locations of KHO scratch regions. Kexec user space tools
+ can use this file in conjunction to scratch_phys to determine where
+ it should place its payload images.
+
+``/sys/kernel/debug/kho/out/sub_fdts/``
+ In the KHO finalization phase, KHO producers register their own
+ FDT blob under this directory.
+
+``/sys/kernel/debug/kho/in/fdt``
+ When the kernel was booted with Kexec HandOver (KHO),
+ the state tree that carries metadata about the previous
+ kernel's state is in this file in the format of flattened
+ device tree. This file may disappear when all consumers of
+ it finished to interpret their metadata.
+
+``/sys/kernel/debug/kho/in/sub_fdts/``
+ Similar to ``kho/out/sub_fdts/``, but contains sub FDT blobs
+ of KHO producers passed from the old kernel.

+=======
+
+The number of candidate pages for KSM is dynamic. It can be often observed

+number of candidate pages to scan. Two advisors are implemented: none and
+scan-time. With none, no advisor is enabled. The default is none.
+
+The scan time advisor changes the ``pages_to_scan`` parameter based on the
+observed scan times. The possible values for the ``pages_to_scan`` parameter is
+limited by the ``advisor_max_cpu`` parameter. In addition there is also the
+``advisor_target_scan_time`` parameter. This parameter sets the target time to
+scan all the KSM candidate pages. The parameter ``advisor_target_scan_time``
+decides how aggressive the scan time advisor scans candidate pages. Lower
+values make the scan time advisor to scan more aggressively. This is the most
+important parameter for the configuration of the scan time advisor.
+
+The initial value and the maximum value can be changed with
+``advisor_min_pages_to_scan`` and ``advisor_max_pages_to_scan``. The default
+values are sufficient for most workloads and use cases.

-Using pagemap to do something useful
-====================================
-
-The general procedure for using pagemap to find out about a process' memory
-usage goes like this:
-
- 1. Read ``/proc/pid/maps`` to determine which parts of the memory space are
- mapped to what.
- 2. Select the maps you are interested in -- all of them, or a particular
- library, or the stack or the heap, etc.
- 3. Open ``/proc/pid/pagemap`` and seek to the pages you would like to examine.
- 4. Read a u64 for each page from pagemap.
- 5. Open ``/proc/kpagecount`` and/or ``/proc/kpageflags``. For each PFN you
- just read, seek to that entry in the file, and read the data you want.
-
-For example, to find the "unique set size" (USS), which is the amount of
-memory that a process is using that is not shared with any other process,
-you can go through every map in the process, find the PFNs, look those up
-in kpagecount, and tally up the number of pages that are only referenced

+ PAGE_IS_PRESENT | PAGE_IS_HUGE,
+ };
+
+The ``PAGE_IS_WRITTEN`` flag can be considered as a better-performing alternative
+of soft-dirty flag. It doesn't get affected by VMA merging of the kernel and hence
+the user can find the true soft-dirty pages in case of normal pages. (There may
+still be extra dirty pages reported for THP or Hugetlb pages.)
+
+"PAGE_IS_WRITTEN" category is used with uffd write protect-enabled ranges to
+implement memory dirty tracking in userspace:
+
+ 1. The userfaultfd file descriptor is created with ``userfaultfd`` syscall.
+ 2. The ``UFFD_FEATURE_WP_UNPOPULATED`` and ``UFFD_FEATURE_WP_ASYNC`` features
+ are set by ``UFFDIO_API`` IOCTL.
+ 3. The memory range is registered with ``UFFDIO_REGISTER_MODE_WP`` mode
+ through ``UFFDIO_REGISTER`` IOCTL.
+ 4. Then any part of the registered memory or the whole memory region must
+ be write protected using ``PAGEMAP_SCAN`` IOCTL with flag ``PM_SCAN_WP_MATCHING``
+ or the ``UFFDIO_WRITEPROTECT`` IOCTL can be used. Both of these perform the
+ same operation. The former is better in terms of performance.
+ 5. Now the ``PAGEMAP_SCAN`` IOCTL can be used to either just find pages which
+ have been written to since they were last marked and/or optionally write protect
+ the pages as well.

+========================================
+Short users guide for the slab allocator
+========================================
+
+The slab allocator includes full debugging support (when built with
+CONFIG_SLUB_DEBUG=y) but it is off by default (unless built with
+CONFIG_SLUB_DEBUG_ON=y). You can enable debugging only for selected
+slabs in order to avoid an impact on overall system performance which
+may make a bug more difficult to find.
+
+In order to switch debugging on one can add an option ``slab_debug``
+to the kernel command line. That will enable full debugging for
+all slabs.
+
+Typically one would then use the ``slabinfo`` command to get statistical
+data and perform operation on the slabs. By default ``slabinfo`` only lists
+slabs that have data in them. See "slabinfo -h" for more options when
+running the command. ``slabinfo`` can be compiled with
+::
+
+ gcc -o slabinfo tools/mm/slabinfo.c
+
+Some of the modes of operation of ``slabinfo`` require that slub debugging
+be enabled on the command line. F.e. no tracking information will be
+available without debugging on and validation can only partially
+be performed if debugging was not switched on.
+
+Some more sophisticated uses of slab_debug:
+-------------------------------------------
+
+Parameters may be given to ``slab_debug``. If none is specified then full
+debugging is enabled. Format:
+
+slab_debug=<Debug-Options>
+ Enable options for all slabs
+
+slab_debug=<Debug-Options>,<slab name1>,<slab name2>,...
+ Enable options only for select slabs (no spaces
+ after a comma)
+
+Multiple blocks of options for all slabs or selected slabs can be given, with
+blocks of options delimited by ';'. The last of "all slabs" blocks is applied
+to all slabs except those that match one of the "select slabs" block. Options
+of the first "select slabs" blocks that matches the slab's name are applied.
+
+Possible debug options are::
+
+ F Sanity checks on (enables SLAB_DEBUG_CONSISTENCY_CHECKS
+ Sorry SLAB legacy issues)
+ Z Red zoning
+ P Poisoning (object and padding)
+ U User tracking (free and alloc)
+ T Trace (please only use on single slabs)
+ A Enable failslab filter mark for the cache
+ O Switch debugging off for caches that would have
+ caused higher minimum slab orders
+ - Switch all debugging off (useful if the kernel is
+ configured with CONFIG_SLUB_DEBUG_ON)
+
+F.e. in order to boot just with sanity checks and red zoning one would specify::
+
+ slab_debug=FZ
+
+Trying to find an issue in the dentry cache? Try::
+
+ slab_debug=,dentry
+
+to only enable debugging on the dentry cache. You may use an asterisk at the
+end of the slab name, in order to cover all slabs with the same prefix. For
+example, here's how you can poison the dentry cache as well as all kmalloc
+slabs::
+
+ slab_debug=P,kmalloc-*,dentry
+
+Red zoning and tracking may realign the slab. We can just apply sanity checks
+to the dentry cache with::
+
+ slab_debug=F,dentry
+
+Debugging options may require the minimum possible slab order to increase as
+a result of storing the metadata (for example, caches with PAGE_SIZE object
+sizes). This has a higher likelihood of resulting in slab allocation errors
+in low memory situations or if there's high fragmentation of memory. To
+switch off debugging for such caches by default, use::
+
+ slab_debug=O
+
+You can apply different options to different list of slab names, using blocks
+of options. This will enable red zoning for dentry and user tracking for
+kmalloc. All other slabs will not get any debugging enabled::
+
+ slab_debug=Z,dentry;U,kmalloc-*
+
+You can also enable options (e.g. sanity checks and poisoning) for all caches
+except some that are deemed too performance critical and don't need to be
+debugged by specifying global debug options followed by a list of slab names
+with "-" as options::
+
+ slab_debug=FZ;-,zs_handle,zspage
+
+The state of each debug option for a slab can be found in the respective files
+under::
+
+ /sys/kernel/slab/<slab name>/
+
+If the file contains 1, the option is enabled, 0 means disabled. The debug
+options from the ``slab_debug`` parameter translate to the following files::
+
+ F sanity_checks
+ Z red_zone
+ P poison
+ U store_user
+ T trace
+ A failslab
+
+failslab file is writable, so writing 1 or 0 will enable or disable
+the option at runtime. Write returns -EINVAL if cache is an alias.
+Careful with tracing: It may spew out lots of information and never stop if
+used on the wrong slab.
+
+Slab merging
+============
+
+If no debug options are specified then SLUB may merge similar slabs together
+in order to reduce overhead and increase cache hotness of objects.
+``slabinfo -a`` displays which slabs were merged together.
+
+Slab validation
+===============
+
+SLUB can validate all object if the kernel was booted with slab_debug. In
+order to do so you must have the ``slabinfo`` tool. Then you can do
+::
+
+ slabinfo -v
+
+which will test all objects. Output will be generated to the syslog.
+
+This also works in a more limited way if boot was without slab debug.
+In that case ``slabinfo -v`` simply tests all reachable objects. Usually
+these are in the cpu slabs and the partial slabs. Full slabs are not
+tracked by SLUB in a non debug situation.
+
+Getting more performance
+========================
+
+To some degree SLUB's performance is limited by the need to take the
+list_lock once in a while to deal with partial slabs. That overhead is
+governed by the order of the allocation for each slab. The allocations
+can be influenced by kernel parameters:
+
+.. slab_min_objects=x (default: automatically scaled by number of cpus)
+.. slab_min_order=x (default 0)
+.. slab_max_order=x (default 3 (PAGE_ALLOC_COSTLY_ORDER))
+
+``slab_min_objects``
+ allows to specify how many objects must at least fit into one
+ slab in order for the allocation order to be acceptable. In
+ general slub will be able to perform this number of
+ allocations on a slab without consulting centralized resources
+ (list_lock) where contention may occur.
+
+``slab_min_order``
+ specifies a minimum order of slabs. A similar effect like
+ ``slab_min_objects``.
+
+``slab_max_order``
+ specified the order at which ``slab_min_objects`` should no
+ longer be checked. This is useful to avoid SLUB trying to
+ generate super large order pages to fit ``slab_min_objects``
+ of a slab cache with large object sizes into one high order
+ page. Setting command line parameter
+ ``debug_guardpage_minorder=N`` (N > 0), forces setting
+ ``slab_max_order`` to 0, what cause minimum possible order of
+ slabs allocation.
+
+``slab_strict_numa``
+ Enables the application of memory policies on each
+ allocation. This results in more accurate placement of
+ objects which may result in the reduction of accesses
+ to remote nodes. The default is to only apply memory
+ policies at the folio level when a new folio is acquired
+ or a folio is retrieved from the lists. Enabling this
+ option reduces the fastpath performance of the slab allocator.

+ =======================
+
+ FIX kmalloc-8: Restoring Redzone 0xc90f6d28-0xc90f6d2b=0xcc
+
+If SLUB encounters a corrupted object (full detection requires the kernel
+to be booted with slab_debug) then the following output will be dumped
+into the syslog:
+
+1. Description of the problem encountered
+
+ This will be a message in the system log starting with::
+
+ ===============================================
+ BUG <slab cache affected>: <What went wrong>
+ -----------------------------------------------
+
+ INFO: <corruption start>-<corruption_end> <more info>
+ INFO: Slab <address> <slab information>
+ INFO: Object <address> <object information>
+ INFO: Allocated in <kernel function> age=<jiffies since alloc> cpu=<allocated by
+ cpu> pid=<pid of the process>
+ INFO: Freed in <kernel function> age=<jiffies since free> cpu=<freed by cpu>
+ pid=<pid of the process>
+
+ (Object allocation / free information is only available if SLAB_STORE_USER is
+ set for the slab. slab_debug sets that option)
+
+2. The object contents if an object was involved.
+
+ Various types of lines can follow the BUG SLUB line:
+
+ Bytes b4 <address> : <bytes>
+ Shows a few bytes before the object where the problem was detected.
+ Can be useful if the corruption does not stop with the start of the
+ object.
+
+ Object <address> : <bytes>
+ The bytes of the object. If the object is inactive then the bytes
+ typically contain poison values. Any non-poison value shows a
+ corruption by a write after free.
+
+ Redzone <address> : <bytes>
+ The Redzone following the object. The Redzone is used to detect
+ writes after the object. All bytes should always have the same
+ value. If there is any deviation then it is due to a write after
+ the object boundary.
+
+ (Redzone information is only available if SLAB_RED_ZONE is set.
+ slab_debug sets that option)
+
+ Padding <address> : <bytes>
+ Unused data to fill up the space in order to get the next object
+ properly aligned. In the debug case we make sure that there are
+ at least 4 bytes of padding. This allows the detection of writes
+ before the object.
+
+3. A stackdump
+
+ The stackdump describes the location where the error was detected. The cause
+ of the corruption is may be more likely found by looking at the function that
+ allocated or freed the object.
+
+4. Report on how the problem was dealt with in order to ensure the continued
+ operation of the system.
+
+ These are messages in the system log beginning with::
+
+ FIX <slab cache affected>: <corrective action taken>
+
+ In the above sample SLUB found that the Redzone of an active object has
+ been overwritten. Here a string of 8 characters was written into a slab that
+ has the length of 8 characters. However, a 8 character string needs a
+ terminating 0. That zero has overwritten the first byte of the Redzone field.
+ After reporting the details of the issue encountered the FIX SLUB message
+ tells us that SLUB has restored the Redzone to its proper value and then
+ system operations continue.
+
+Emergency operations
+====================
+
+Minimal debugging (sanity checks alone) can be enabled by booting with::
+
+ slab_debug=F
+
+This will be generally be enough to enable the resiliency features of slub
+which will keep the system running even if a bad kernel component will
+keep corrupting objects. This may be important for production systems.
+Performance will be impacted by the sanity checks and there will be a
+continual stream of error messages to the syslog but no additional memory
+will be used (unlike full debugging).
+
+No guarantees. The kernel component still needs to be fixed. Performance
+may be optimized further by locating the slab that experiences corruption
+and enabling debugging only for that cache
+
+I.e.::
+
+ slab_debug=F,dentry
+
+If the corruption occurs by writing after the end of the object then it
+may be advisable to enable a Redzone to avoid corrupting the beginning
+of other objects::
+
+ slab_debug=FZ,dentry
+
+Extended slabinfo mode and plotting
+===================================
+
+The ``slabinfo`` tool has a special 'extended' ('-X') mode that includes:
+ - Slabcache Totals
+ - Slabs sorted by size (up to -N <num> slabs, default 1)
+ - Slabs sorted by loss (up to -N <num> slabs, default 1)
+
+Additionally, in this mode ``slabinfo`` does not dynamically scale
+sizes (G/M/K) and reports everything in bytes (this functionality is
+also available to other slabinfo modes via '-B' option) which makes
+reporting more precise and accurate. Moreover, in some sense the `-X'
+mode also simplifies the analysis of slabs' behaviour, because its
+output can be plotted using the ``slabinfo-gnuplot.sh`` script. So it
+pushes the analysis from looking through the numbers (tons of numbers)
+to something easier -- visual analysis.
+
+To generate plots:
+
+a) collect slabinfo extended records, for example::
+
+ while [ 1 ]; do slabinfo -X >> FOO_STATS; sleep 1; done
+
+b) pass stats file(-s) to ``slabinfo-gnuplot.sh`` script::
+
+ slabinfo-gnuplot.sh FOO_STATS [FOO_STATS2 .. FOO_STATSN]
+
+ The ``slabinfo-gnuplot.sh`` script will pre-processes the collected records
+ and generates 3 png files (and 3 pre-processing cache files) per STATS
+ file:
+ - Slabcache Totals: FOO_STATS-totals.png
+ - Slabs sorted by size: FOO_STATS-slabs-by-size.png
+ - Slabs sorted by loss: FOO_STATS-slabs-by-loss.png
+
+Another use case, when ``slabinfo-gnuplot.sh`` can be useful, is when you
+need to compare slabs' behaviour "prior to" and "after" some code
+modification. To help you out there, ``slabinfo-gnuplot.sh`` script
+can 'merge' the `Slabcache Totals` sections from different
+measurements. To visually compare N plots:
+
+a) Collect as many STATS1, STATS2, .. STATSN files as you need::
+
+ while [ 1 ]; do slabinfo -X >> STATS<X>; sleep 1; done
+
+b) Pre-process those STATS files::
+
+ slabinfo-gnuplot.sh STATS1 STATS2 .. STATSN
+
+c) Execute ``slabinfo-gnuplot.sh`` in '-t' mode, passing all of the
+ generated pre-processed \*-totals::
+
+ slabinfo-gnuplot.sh -t STATS1-totals STATS2-totals .. STATSN-totals
+
+ This will produce a single plot (png file).
+
+ Plots, expectedly, can be large so some fluctuations or small spikes
+ can go unnoticed. To deal with that, ``slabinfo-gnuplot.sh`` has two
+ options to 'zoom-in'/'zoom-out':
+
+ a) ``-s %d,%d`` -- overwrites the default image width and height
+ b) ``-r %d,%d`` -- specifies a range of samples to use (for example,
+ in ``slabinfo -X >> FOO_STATS; sleep 1;`` case, using a ``-r
+ 40,60`` range will plot only samples collected between 40th and
+ 60th seconds).
+
+
+DebugFS files for SLUB
+======================
+
+For more information about current state of SLUB caches with the user tracking
+debug option enabled, debugfs files are available, typically under
+/sys/kernel/debug/slab/<cache>/ (created only for caches with enabled user
+tracking). There are 2 types of these files with the following debug
+information:
+
+1. alloc_traces::
+
+ Prints information about unique allocation traces of the currently
+ allocated objects. The output is sorted by frequency of each trace.
+
+ Information in the output:
+ Number of objects, allocating function, possible memory wastage of
+ kmalloc objects(total/per-object), minimal/average/maximal jiffies
+ since alloc, pid range of the allocating processes, cpu mask of
+ allocating cpus, numa node mask of origins of memory, and stack trace.
+
+ Example:::
+
+ 338 pci_alloc_dev+0x2c/0xa0 waste=521872/1544 age=290837/291891/293509 pid=1 cpus=106 nodes=0-1

+ acpi_dev_for_each_child+0x77/0xa0
+ acpi_bus_attach+0x108/0x3f0
+
+2. free_traces::
+
+ Prints information about unique freeing traces of the currently allocated
+ objects. The freeing traces thus come from the previous life-cycle of the
+ objects and are reported as not available for objects allocated for the first
+ time. The output is sorted by frequency of each trace.
+
+ Information in the output:
+ Number of objects, freeing function, minimal/average/maximal jiffies since free,
+ pid range of the freeing processes, cpu mask of freeing cpus, and stack trace.
+
+ Example:::
+
+ 1980 <not-available> age=4294912290 pid=0 cpus=0
+ 51 acpi_ut_update_ref_count+0x6a6/0x782 age=236886/237027/237772 pid=1 cpus=1

-===========================================
-Automatically bind swap device to numa node
-===========================================
-
-If the system has more than one swap device and swap device has the node
-information, we can make use of this information to decide which swap
-device to use in get_swap_pages() to get better performance.
-
-
-How to use this feature
-=======================
-
-Swap device has priority and that decides the order of it to be used. To make
-use of automatically binding, there is no need to manipulate priority settings
-for swap devices. e.g. on a 2 node machine, assume 2 swap devices swapA and
-swapB, with swapA attached to node 0 and swapB attached to node 1, are going
-to be swapped on. Simply swapping them on by doing::
-
- # swapon /dev/swapA
- # swapon /dev/swapB
-
-Then node 0 will use the two swap devices in the order of swapA then swapB and
-node 1 will use the two swap devices in the order of swapB then swapA. Note
-that the order of them being swapped on doesn't matter.
-
-A more complex example on a 4 node machine. Assume 6 swap devices are going to
-be swapped on: swapA and swapB are attached to node 0, swapC is attached to
-node 1, swapD and swapE are attached to node 2 and swapF is attached to node3.
-The way to swap them on is the same as above::
-
- # swapon /dev/swapA
- # swapon /dev/swapB
- # swapon /dev/swapC
- # swapon /dev/swapD
- # swapon /dev/swapE
- # swapon /dev/swapF
-
-Then node 0 will use them in the order of::
-
- swapA/swapB -> swapC -> swapD -> swapE -> swapF
-
-swapA and swapB will be used in a round robin mode before any other swap device.
-
-node 1 will use them in the order of::
-
- swapC -> swapA -> swapB -> swapD -> swapE -> swapF
-
-node 2 will use them in the order of::
-
- swapD/swapE -> swapA -> swapB -> swapC -> swapF
-
-Similaly, swapD and swapE will be used in a round robin mode before any
-other swap devices.
-
-node 3 will use them in the order of::
-
- swapF -> swapA -> swapB -> swapC -> swapD -> swapE
-
-
-Implementation details
-======================
-
-The current code uses a priority based list, swap_avail_list, to decide
-which swap device to use and if multiple swap devices share the same
-priority, they are used round robin. This change here replaces the single
-global swap_avail_list with a per-numa-node list, i.e. for each numa node,
-it sees its own priority based list of available swap devices. Swap
-device's priority can be promoted on its matching node's swap_avail_list.
-
-The current swap device's priority is set as: user can set a >=0 value,
-or the system will pick one starting from -1 then downwards. The priority
-value in the swap_avail_list is the negated value of the swap device's
-due to plist being sorted from low to high. The new policy doesn't change
-the semantics for priority >=0 cases, the previous starting from -1 then
-downwards now becomes starting from -2 then downwards and -1 is reserved
-as the promoted value. So if multiple swap devices are attached to the same
-node, they will all be promoted to priority -1 on that node's plist and will
-be used round robin before any other swap devices.

+===============
+
+You can change the sysfs boot time default for the top-level "enabled"
+control by passing the parameter ``transparent_hugepage=always`` or
+``transparent_hugepage=madvise`` or ``transparent_hugepage=never`` to the
+kernel command line.
+
+Alternatively, each supported anonymous THP size can be controlled by
+passing ``thp_anon=<size>[KMG],<size>[KMG]:<state>;<size>[KMG]-<size>[KMG]:<state>``,
+where ``<size>`` is the THP size (must be a power of 2 of PAGE_SIZE and
+supported anonymous THP) and ``<state>`` is one of ``always``, ``madvise``,
+``never`` or ``inherit``.
+
+For example, the following will set 16K, 32K, 64K THP to ``always``,
+set 128K, 512K to ``inherit``, set 256K to ``madvise`` and 1M, 2M
+to ``never``::
+
+ thp_anon=16K-64K:always;128K,512K:inherit;256K:madvise;1M-2M:never
+
+``thp_anon=`` may be specified multiple times to configure all THP sizes as
+required. If ``thp_anon=`` is specified at least once, any anon THP sizes
+not explicitly configured on the command line are implicitly set to
+``never``.
+
+``transparent_hugepage`` setting only affects the global toggle. If
+``thp_anon`` is not specified, PMD_ORDER THP will default to ``inherit``.
+However, if a valid ``thp_anon`` setting is provided by the user, the
+PMD_ORDER THP policy will be overridden. If the policy for PMD_ORDER
+is not defined within a valid ``thp_anon``, its policy will default to
+``never``.
+
+Similarly to ``transparent_hugepage``, you can control the hugepage
+allocation policy for the internal shmem mount by using the kernel parameter
+``transparent_hugepage_shmem=<policy>``, where ``<policy>`` is one of the
+seven valid policies for shmem (``always``, ``within_size``, ``advise``,
+``never``, ``deny``, and ``force``).
+
+Similarly to ``transparent_hugepage_shmem``, you can control the default
+hugepage allocation policy for the tmpfs mount by using the kernel parameter
+``transparent_hugepage_tmpfs=<policy>``, where ``<policy>`` is one of the
+four valid policies for tmpfs (``always``, ``within_size``, ``advise``,
+``never``). The tmpfs mount default policy is ``never``.
+
+Additionally, Kconfig options are available to set the default hugepage
+policies for shmem (``CONFIG_TRANSPARENT_HUGEPAGE_SHMEM_HUGE_*``) and tmpfs
+(``CONFIG_TRANSPARENT_HUGEPAGE_TMPFS_HUGE_*``) at build time. Refer to the
+Kconfig help for more details.
+
+In the same manner as ``thp_anon`` controls each supported anonymous THP
+size, ``thp_shmem`` controls each supported shmem THP size. ``thp_shmem``
+has the same format as ``thp_anon``, but also supports the policy
+``within_size``.
+
+``thp_shmem=`` may be specified multiple times to configure all THP sizes
+as required. If ``thp_shmem=`` is specified at least once, any shmem THP
+sizes not explicitly configured on the command line are implicitly set to
+``never``.
+
+``transparent_hugepage_shmem`` setting only affects the global toggle. If
+``thp_shmem`` is not specified, PMD_ORDER hugepage will default to
+``inherit``. However, if a valid ``thp_shmem`` setting is provided by the
+user, the PMD_ORDER hugepage policy will be overridden. If the policy for
+PMD_ORDER is not defined within a valid ``thp_shmem``, its policy will
+default to ``never``.
Hugepages in tmpfs/shmem
========================
-You can control hugepage allocation policy in tmpfs with mount option
-``huge=``. It can have following values:
+Traditionally, tmpfs only supported a single huge page size ("PMD"). Today,
+it also supports smaller sizes just like anonymous memory, often referred
+to as "multi-size THP" (mTHP). Huge pages of any size are commonly
+represented in the kernel as "large folios".
+
+While there is fine control over the huge page sizes to use for the internal
+shmem mount (see below), ordinary tmpfs mounts will make use of all available
+huge page sizes without any control over the exact sizes, behaving more like
+other file systems.
+
+tmpfs mounts
+------------
+
+The THP allocation policy for tmpfs mounts can be adjusted using the mount
+option: ``huge=``. It can have following values:
always
Attempt to allocate huge pages every time we need a new page;
+ Always try PMD-sized huge pages first, and fall back to smaller-sized
+ huge pages if the PMD-sized huge page allocation fails;
never
- Do not allocate huge pages;

``mount -o remount,huge= /mountpoint`` works fine after mount: remounting

+
+For anonymous memory, ``ioctl(UFFDIO_WRITEPROTECT)`` will ignore none ptes
+(e.g. when pages are missing and not populated). For file-backed memories
+like shmem and hugetlbfs, none ptes will be write protected just like a
+present pte. In other words, there will be a userfaultfd write fault
+message generated when writing to a missing page on file typed memories,
+as long as the page range was write-protected before. Such a message will
+not be generated on anonymous memories by default.
+
+If the application wants to be able to write protect none ptes on anonymous
+memory, one can pre-populate the memory with e.g. MADV_POPULATE_READ. On
+newer kernels, one can also detect the feature UFFD_FEATURE_WP_UNPOPULATED
+and set the feature bit in advance to make sure none ptes will also be
+write protected even upon anonymous memory.
+
+When using ``UFFDIO_REGISTER_MODE_WP`` in combination with either
+``UFFDIO_REGISTER_MODE_MISSING`` or ``UFFDIO_REGISTER_MODE_MINOR``, when
+resolving missing / minor faults with ``UFFDIO_COPY`` or ``UFFDIO_CONTINUE``

+respectively) to configure the mapping this way.
+
+If the userfaultfd context has ``UFFD_FEATURE_WP_ASYNC`` feature bit set,

+
+In async mode, there will be no message generated when a write operation
+happens, meanwhile the write-protection will be resolved automatically by

+
+ - The dirty result will not be affected by vma changes (e.g. vma
+ merging) because the dirty is only tracked by the pte.
+
+ - It supports range operations by default, so one can enable tracking on
+ any range of memory as long as page aligned.
+
+ - Dirty information will not get lost if the pte was zapped due to
+ various reasons (e.g. during split of a shmem transparent huge page).
+
+ - Due to a reverted meaning of soft-dirty (page clean when uffd-wp bit
+ set; dirty when uffd-wp bit cleared), it has different semantics on
+ some of the memory operations. For example: ``MADV_DONTNEED`` on
+ anonymous (or ``MADV_REMOVE`` on a file mapping) will be treated as
+ dirtying of memory by dropping uffd-wp bit during the procedure.

+The user app can collect the "written/dirty" status by looking up the
+uffd-wp bit for the pages being interested in /proc/pagemap.
+
+The page will not be under track of uffd-wp async mode until the page is
+explicitly write-protected by ``ioctl(UFFDIO_WRITEPROTECT)`` with the mode
+flag ``UFFDIO_WRITEPROTECT_MODE_WP`` set. Trying to resolve a page fault
+that was tracked by async mode userfaultfd-wp is invalid.
+
+When userfaultfd-wp async mode is used alone, it can be applied to all
+kinds of memory.
+
+Memory Poisioning Emulation
+---------------------------
+
+In response to a fault (either missing or minor), an action userspace can
+take to "resolve" it is to issue a ``UFFDIO_POISON``. This will cause any
+future faulters to either get a SIGBUS, or in KVM's case the guest will
+receive an MCE as if there were hardware memory poisoning.
+
+This is used to emulate hardware memory poisoning. Imagine a VM running on a
+machine which experiences a real hardware memory error. Later, we live migrate
+the VM to another physical machine. Since we want the migration to be
+transparent to the guest, we want that same address range to act as if it was
+still poisoned, even though it's on a new physical host which ostensibly
+doesn't have a memory error in the exact same spot.

+Linux NVMe multipath
+====================
+
+This document describes NVMe multipath and its path selection policies supported
+by the Linux NVMe host driver.
+
+
+Introduction
+============
+
+The NVMe multipath feature in Linux integrates namespaces with the same
+identifier into a single block device. Using multipath enhances the reliability
+and stability of I/O access while improving bandwidth performance. When a user
+sends I/O to this merged block device, the multipath mechanism selects one of
+the underlying block devices (paths) according to the configured policy.
+Different policies result in different path selections.
+
+
+Policies
+========
+
+All policies follow the ANA (Asymmetric Namespace Access) mechanism, meaning
+that when an optimized path is available, it will be chosen over a non-optimized
+one. Current the NVMe multipath policies include numa(default), round-robin and
+queue-depth.
+
+To set the desired policy (e.g., round-robin), use one of the following methods:
+ 1. echo -n "round-robin" > /sys/module/nvme_core/parameters/iopolicy
+ 2. or add the "nvme_core.iopolicy=round-robin" to cmdline.
+
+
+NUMA
+----
+
+The NUMA policy selects the path closest to the NUMA node of the current CPU for
+I/O distribution. This policy maintains the nearest paths to each NUMA node
+based on network interface connections.
+
+When to use the NUMA policy:
+ 1. Multi-core Systems: Optimizes memory access in multi-core and
+ multi-processor systems, especially under NUMA architecture.
+ 2. High Affinity Workloads: Binds I/O processing to the CPU to reduce
+ communication and data transfer delays across nodes.
+
+
+Round-Robin
+-----------
+
+The round-robin policy distributes I/O requests evenly across all paths to
+enhance throughput and resource utilization. Each I/O operation is sent to the
+next path in sequence.
+
+When to use the round-robin policy:
+ 1. Balanced Workloads: Effective for balanced and predictable workloads with
+ similar I/O size and type.
+ 2. Homogeneous Path Performance: Utilizes all paths efficiently when
+ performance characteristics (e.g., latency, bandwidth) are similar.
+
+
+Queue-Depth
+-----------
+
+The queue-depth policy manages I/O requests based on the current queue depth
+of each path, selecting the path with the least number of in-flight I/Os.
+
+When to use the queue-depth policy:
+ 1. High load with small I/Os: Effectively balances load across paths when
+ the load is high, and I/O operations consist of small, relatively
+ fixed-sized requests.

+======================================================================
+
+DesignWare Cores (DWC) PCIe PMU
+===============================
+
+The PMU is a PCIe configuration space register block provided by each PCIe Root
+Port in a Vendor-Specific Extended Capability named RAS D.E.S (Debug, Error
+injection, and Statistics).
+
+As the name indicates, the RAS DES capability supports system level
+debugging, AER error injection, and collection of statistics. To facilitate
+collection of statistics, Synopsys DesignWare Cores PCIe controller
+provides the following two features:
+
+- one 64-bit counter for Time Based Analysis (RX/TX data throughput and
+ time spent in each low-power LTSSM state) and
+- one 32-bit counter per event for Event Counting (error and non-error
+ events for a specified lane)
+
+Note: There is no interrupt for counter overflow.
+
+Time Based Analysis
+-------------------
+
+Using this feature you can obtain information regarding RX/TX data
+throughput and time spent in each low-power LTSSM state by the controller.
+The PMU measures data in two categories:
+
+- Group#0: Percentage of time the controller stays in LTSSM states.
+- Group#1: Amount of data processed (Units of 16 bytes).
+
+Lane Event counters
+-------------------
+
+Using this feature you can obtain Error and Non-Error information in
+specific lane by the controller. The PMU event is selected by all of:
+
+- Group i
+- Event j within the Group i
+- Lane k
+
+Some of the events only exist for specific configurations.
+
+DesignWare Cores (DWC) PCIe PMU Driver
+=======================================
+
+This driver adds PMU devices for each PCIe Root Port named based on the SBDF of
+the Root Port. For example,
+
+ 0001:30:03.0 PCI bridge: Device 1ded:8000 (rev 01)
+
+the PMU device name for this Root Port is dwc_rootport_13018.
+
+The DWC PCIe PMU driver registers a perf PMU driver, which provides
+description of available events and configuration options in sysfs, see
+/sys/bus/event_source/devices/dwc_rootport_{sbdf}.
+
+The "format" directory describes format of the config fields of the
+perf_event_attr structure. The "events" directory provides configuration
+templates for all documented events. For example,
+"rx_pcie_tlp_data_payload" is an equivalent of "eventid=0x21,type=0x0".
+
+The "perf list" command shall list the available events from sysfs, e.g.::
+
+ $# perf list | grep dwc_rootport
+ <...>
+ dwc_rootport_13018/Rx_PCIe_TLP_Data_Payload/ [Kernel PMU event]
+ <...>
+ dwc_rootport_13018/rx_memory_read,lane=?/ [Kernel PMU event]
+
+Time Based Analysis Event Usage
+-------------------------------
+
+Example usage of counting PCIe RX TLP data payload (Units of bytes)::
+
+ $# perf stat -a -e dwc_rootport_13018/Rx_PCIe_TLP_Data_Payload/
+
+The average RX/TX bandwidth can be calculated using the following formula:
+
+ PCIe RX Bandwidth = rx_pcie_tlp_data_payload / Measure_Time_Window
+ PCIe TX Bandwidth = tx_pcie_tlp_data_payload / Measure_Time_Window
+
+Lane Event Usage
+-------------------------------
+
+Each lane has the same event set and to avoid generating a list of hundreds
+of events, the user need to specify the lane ID explicitly, e.g.::
+
+ $# perf stat -a -e dwc_rootport_13018/rx_memory_read,lane=4/

+================================================
+Fujitsu Uncore Performance Monitoring Unit (PMU)
+================================================
+
+This driver supports the Uncore MAC PMUs and the Uncore PCI PMUs found
+in Fujitsu chips.
+Each MAC PMU on these chips is exposed as a uncore perf PMU with device name
+mac_iod<iod>_mac<mac>_ch<ch>.
+And each PCI PMU on these chips is exposed as a uncore perf PMU with device name
+pci_iod<iod>_pci<pci>.
+
+The driver provides a description of its available events and configuration
+options in sysfs, see /sys/bus/event_sources/devices/mac_iod<iod>_mac<mac>_ch<ch>/
+and /sys/bus/event_sources/devices/pci_iod<iod>_pci<pci>/.

+
+This driver supports the following events for MAC:
+
+- cycles
+ This event counts MAC cycles at MAC frequency.
+- read-count
+ This event counts the number of read requests to MAC.
+- read-count-request
+ This event counts the number of read requests including retry to MAC.
+- read-count-return
+ This event counts the number of responses to read requests to MAC.
+- read-count-request-pftgt
+ This event counts the number of read requests including retry with PFTGT
+ flag.
+- read-count-request-normal
+ This event counts the number of read requests including retry without PFTGT
+ flag.
+- read-count-return-pftgt-hit
+ This event counts the number of responses to read requests which hit the
+ PFTGT buffer.
+- read-count-return-pftgt-miss
+ This event counts the number of responses to read requests which miss the
+ PFTGT buffer.
+- read-wait
+ This event counts outstanding read requests issued by DDR memory controller
+ per cycle.
+- write-count
+ This event counts the number of write requests to MAC (including zero write,
+ full write, partial write, write cancel).
+- write-count-write
+ This event counts the number of full write requests to MAC (not including
+ zero write).
+- write-count-pwrite
+ This event counts the number of partial write requests to MAC.
+- memory-read-count
+ This event counts the number of read requests from MAC to memory.
+- memory-write-count
+ This event counts the number of full write requests from MAC to memory.
+- memory-pwrite-count
+ This event counts the number of partial write requests from MAC to memory.
+- ea-mac
+ This event counts energy consumption of MAC.
+- ea-memory
+ This event counts energy consumption of memory.
+- ea-memory-mac-write
+ This event counts the number of write requests from MAC to memory.
+- ea-ha
+ This event counts energy consumption of HA.
+
+ 'ea' is the abbreviation for 'Energy Analyzer'.
+
+Examples for use with perf::
+
+ perf stat -e mac_iod0_mac0_ch0/ea-mac/ ls
+
+And, this driver supports the following events for PCI:
+
+- pci-port0-cycles
+ This event counts PCI cycles at PCI frequency in port0.
+- pci-port0-read-count
+ This event counts read transactions for data transfer in port0.
+- pci-port0-read-count-bus
+ This event counts read transactions for bus usage in port0.
+- pci-port0-write-count
+ This event counts write transactions for data transfer in port0.
+- pci-port0-write-count-bus
+ This event counts write transactions for bus usage in port0.
+- pci-port1-cycles
+ This event counts PCI cycles at PCI frequency in port1.
+- pci-port1-read-count
+ This event counts read transactions for data transfer in port1.
+- pci-port1-read-count-bus
+ This event counts read transactions for bus usage in port1.
+- pci-port1-write-count
+ This event counts write transactions for data transfer in port1.
+- pci-port1-write-count-bus
+ This event counts write transactions for bus usage in port1.
+- ea-pci
+ This event counts energy consumption of PCI.
+
+ 'ea' is the abbreviation for 'Energy Analyzer'.
+
+Examples for use with perf::
+
+ perf stat -e pci_iod0_pci0/ea-pci/ ls
+
+Given that these are uncore PMUs the driver does not support sampling, therefore

+all the TADs. The user would end up effectively reserving one of
+eight counters in every TAD to look across all TADs.
+The occurrences of events are aggregated and presented to the user
+at the end of running the workload. The driver does not provide a

+different applications.

+Support for Hybrid Processors
+=============================
+
+Some processors supported by ``intel_pstate`` contain two or more types of CPU
+cores differing by the maximum turbo P-state, performance vs power characteristics,
+cache sizes, and possibly other properties. They are commonly referred to as
+hybrid processors. To support them, ``intel_pstate`` requires HWP to be enabled
+and it assumes the HWP performance units to be the same for all CPUs in the
+system, so a given HWP performance level always represents approximately the
+same physical performance regardless of the core (CPU) type.
+
+Hybrid Processors with SMT
+--------------------------
+
+On systems where SMT (Simultaneous Multithreading), also referred to as
+HyperThreading (HT) in the context of Intel processors, is enabled on at least
+one core, ``intel_pstate`` assigns performance-based priorities to CPUs. Namely,
+the priority of a given CPU reflects its highest HWP performance level which
+causes the CPU scheduler to generally prefer more performant CPUs, so the less
+performant CPUs are used when the other ones are fully loaded. However, SMT
+siblings (that is, logical CPUs sharing one physical core) are treated in a
+special way such that if one of them is in use, the effective priority of the
+other ones is lowered below the priorities of the CPUs located in the other
+physical cores.
+
+This approach maximizes performance in the majority of cases, but unfortunately
+it also leads to excessive energy usage in some important scenarios, like video
+playback, which is not generally desirable. While there is no other viable
+choice with SMT enabled because the effective capacity and utilization of SMT
+siblings are hard to determine, hybrid processors without SMT can be handled in
+more energy-efficient ways.
+
+.. _CAS:
+
+Capacity-Aware Scheduling Support
+---------------------------------
+
+The capacity-aware scheduling (CAS) support in the CPU scheduler is enabled by
+``intel_pstate`` by default on hybrid processors without SMT. CAS generally
+causes the scheduler to put tasks on a CPU so long as there is a sufficient
+amount of spare capacity on it, and if the utilization of a given task is too
+high for it, the task will need to go somewhere else.
+
+Since CAS takes CPU capacities into account, it does not require CPU
+prioritization and it allows tasks to be distributed more symmetrically among
+the more performant and less performant CPUs. Once placed on a CPU with enough
+capacity to accommodate it, a task may just continue to run there regardless of
+whether or not the other CPUs are fully loaded, so on average CAS reduces the
+utilization of the more performant CPUs which causes the energy usage to be more
+balanced because the more performant CPUs are generally less energy-efficient
+than the less performant ones.
+
+In order to use CAS, the scheduler needs to know the capacity of each CPU in
+the system and it needs to be able to compute scale-invariant utilization of
+CPUs, so ``intel_pstate`` provides it with the requisite information.
+
+First of all, the capacity of each CPU is represented by the ratio of its highest
+HWP performance level, multiplied by 1024, to the highest HWP performance level
+of the most performant CPU in the system, which works because the HWP performance
+units are the same for all CPUs. Second, the frequency-invariance computations,
+carried out by the scheduler to always express CPU utilization in the same units
+regardless of the frequency it is currently running at, are adjusted to take the
+CPU capacity into account. All of this happens when ``intel_pstate`` has
+registered itself with the ``CPUFreq`` core and it has figured out that it is
+running on a hybrid processor without SMT.
+
+Energy-Aware Scheduling Support
+-------------------------------
+
+If ``CONFIG_ENERGY_MODEL`` has been set during kernel configuration and
+``intel_pstate`` runs on a hybrid processor without SMT, in addition to enabling
+:ref:`CAS` it registers an Energy Model for the processor. This allows the
+Energy-Aware Scheduling (EAS) support to be enabled in the CPU scheduler if
+``schedutil`` is used as the ``CPUFreq`` governor which requires ``intel_pstate``
+to operate in the :ref:`passive mode <passive_mode>`.
+
+The Energy Model registered by ``intel_pstate`` is artificial (that is, it is
+based on abstract cost values and it does not include any real power numbers)
+and it is relatively simple to avoid unnecessary computations in the scheduler.
+There is a performance domain in it for every CPU in the system and the cost
+values for these performance domains have been chosen so that running a task on
+a less performant (small) CPU appears to be always cheaper than running that
+task on a more performant (big) CPU. However, for two CPUs of the same type,
+the cost difference depends on their current utilization, and the CPU whose
+current utilization is higher generally appears to be a more expensive
+destination for a given task. This helps to balance the load among CPUs of the
+same type.
+
+Since EAS works on top of CAS, high-utilization tasks are always migrated to
+CPUs with enough capacity to accommodate them, but thanks to EAS, low-utilization
+tasks tend to be placed on the CPUs that look less expensive to the scheduler.
+Effectively, this causes the less performant and less loaded CPUs to be
+preferred as long as they have enough spare capacity to run the given task
+which generally leads to reduced energy usage.
+
+The Energy Model created by ``intel_pstate`` can be inspected by looking at
+the ``energy_model`` directory in ``debugfs`` (typlically mounted on
+``/sys/kernel/debug/``).

+
+An SoC can contain multiple power domains with individual or collection

+Interface), can have multiple power domains. Each power domain can
+contain one or more fabric clusters.
+
+To represent controls at fabric cluster level in addition to the
+controls at package and die level (like systems without TPMI
+support), sysfs is enhanced. This granular interface is presented in the
+sysfs with directories names prefixed with "uncore". For example:
+uncore00, uncore01 etc.
+
+The scope of control is specified by attributes "package_id", "domain_id"
+and "fabric_cluster_id" in the directory.
+
+Attributes in each directory:
+
+``domain_id``
+ This attribute is used to get the power domain id of this instance.
+
+``die_id``
+ This attribute is used to get the Linux die id of this instance.
+ This attribute is only present for domains with core agents and

+
+When user uses controls at "package_*_die_*" level, then every fabric

+"max_freq_khz" in the package_00_die_00, then "max_freq_khz" for uncore*
+directory with the same package id will be updated. In this case user can
+still update "max_freq_khz" at each uncore* level, which is more restrictive.
+Similarly, user can update "min_freq_khz" at "package_*_die_*" level
+to apply at each uncore* level.
+
+Support for "current_freq_khz" is available only at each fabric cluster
+level (i.e., in uncore* directory).
+
+Efficiency vs. Latency Tradeoff
+-------------------------------
+
+The Efficiency Latency Control (ELC) feature improves performance
+per watt. With this feature hardware power management algorithms
+optimize trade-off between latency and power consumption. For some
+latency sensitive workloads further tuning can be done by SW to
+get desired performance.
+
+The hardware monitors the average CPU utilization across all cores
+in a power domain at regular intervals and decides an uncore frequency.
+While this may result in the best performance per watt, workload may be
+expecting higher performance at the expense of power. Consider an
+application that intermittently wakes up to perform memory reads on an
+otherwise idle system. In such cases, if hardware lowers uncore
+frequency, then there may be delay in ramp up of frequency to meet
+target performance.
+
+The ELC control defines some parameters which can be changed from SW.
+If the average CPU utilization is below a user-defined threshold
+(elc_low_threshold_percent attribute below), the user-defined uncore
+floor frequency will be used (elc_floor_freq_khz attribute below)
+instead of hardware calculated minimum.
+
+Similarly in high load scenario where the CPU utilization goes above
+the high threshold value (elc_high_threshold_percent attribute below)
+instead of jumping to maximum uncore frequency, frequency is increased
+in 100MHz steps. This avoids consuming unnecessarily high power
+immediately with CPU utilization spikes.
+
+Attributes for efficiency latency control:
+
+``elc_floor_freq_khz``
+ This attribute is used to get/set the efficiency latency floor frequency.
+ If this variable is lower than the 'min_freq_khz', it is ignored by
+ the firmware.
+
+``elc_low_threshold_percent``
+ This attribute is used to get/set the efficiency latency control low
+ threshold. This attribute is in percentages of CPU utilization.
+
+``elc_high_threshold_percent``
+ This attribute is used to get/set the efficiency latency control high
+ threshold. This attribute is in percentages of CPU utilization.
+
+``elc_high_threshold_enable``
+ This attribute is used to enable/disable the efficiency latency control
+ high threshold. Write '1' to enable, '0' to disable.
+
+Example system configuration below, which does following:
+ * when CPU utilization is less than 10%: sets uncore frequency to 800MHz
+ * when CPU utilization is higher than 95%: increases uncore frequency in
+ 100MHz steps, until power limit is reached

+How to quickly build a trimmed Linux kernel
+===========================================
+
+This guide explains how to swiftly build Linux kernels that are ideal for
+testing purposes, but perfectly fine for day-to-day use, too.
+
+The essence of the process (aka 'TL;DR')
+========================================
+
+*[If you are new to compiling Linux, ignore this TLDR and head over to the next
+section below: it contains a step-by-step guide, which is more detailed, but
+still brief and easy to follow; that guide and its accompanying reference
+section also mention alternatives, pitfalls, and additional aspects, all of
+which might be relevant for you.]*
+
+If your system uses techniques like Secure Boot, prepare it to permit starting
+self-compiled Linux kernels; install compilers and everything else needed for
+building Linux; make sure to have 12 Gigabyte free space in your home directory.
+Now run the following commands to download fresh Linux mainline sources, which
+you then use to configure, build and install your own kernel::
+
+ git clone --depth 1 -b master \
+ https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git ~/linux/
+ cd ~/linux/

+ # have to, if you are running Debian. See below for details.
+ make -j $(nproc --all)
+ # Note: on many commodity distributions the next command suffices, but on Arch
+ # Linux, its derivatives, and some others it does not. See below for details.
+ command -v installkernel && sudo make modules_install install
+ reboot
+
+If you later want to build a newer mainline snapshot, use these commands::
+
+ cd ~/linux/
+ git fetch --depth 1 origin
+ # Note: the next command will discard any changes you did to the code:
+ git checkout --force --detach origin/master
+ # Reminder: if you want to (re)apply patches, do it at this point.

+
+Step-by-step guide
+==================
+
+Compiling your own Linux kernel is easy in principle. There are various ways to
+do it. Which of them actually work and is the best depends on the circumstances.
+
+This guide describes a way perfectly suited for those who want to quickly
+install Linux from sources without being bothered by complicated details; the
+goal is to cover everything typically needed on mainstream Linux distributions
+running on commodity PC or server hardware.
+
+The described approach is great for testing purposes, for example to try a
+proposed fix or to check if a problem was already fixed in the latest codebase.
+Nonetheless, kernels built this way are also totally fine for day-to-day use
+while at the same time being easy to keep up to date.
+
+The following steps describe the important aspects of the process; a
+comprehensive reference section later explains each of them in more detail. It
+sometimes also describes alternative approaches, pitfalls, as well as errors
+that might occur at a particular point -- and how to then get things rolling
+again.
+
+..
+ Note: if you see this note, you are reading the text's source file. You
+ might want to switch to a rendered version, as it makes it a lot easier to

+
+ * Create a fresh backup and put system repair and restore tools at hand, just

+
+ [:ref:`details<backup>`]
+
+.. _secureboot_sbs:
+
+ * On platforms with 'Secure Boot' or similar techniques, prepare everything to
+ ensure the system will permit your self-compiled kernel to boot later. The
+ quickest and easiest way to achieve this on commodity x86 systems is to
+ disable such techniques in the BIOS setup utility; alternatively, remove
+ their restrictions through a process initiated by
+ ``mokutil --disable-validation``.
+

+
+.. _buildrequires_sbs:
+
+ * Install all software required to build a Linux kernel. Often you will need:
+ 'bc', 'binutils' ('ld' et al.), 'bison', 'flex', 'gcc', 'git', 'openssl',
+ 'pahole', 'perl', and the development headers for 'libelf' and 'openssl'. The

+
+ * Ensure to have enough free space for building and installing Linux. For the
+ latter 150 Megabyte in /lib/ and 100 in /boot/ are a safe bet. For storing

+ typically suffice. If you have less available, be sure to check the reference

+ will avoid some* :ref:`peculiar characteristics of shallow clones the
+ reference section explains<sources_shallow>` *.]*
+
+ First, execute the following command to retrieve a fresh mainline codebase::
+
+ git clone --no-checkout --depth 1 -b master \
+ https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git ~/linux/
+ cd ~/linux/
+
+ If you want to access recent mainline releases and pre-releases, deepen you
+ clone's history to the oldest mainline version you are interested in::
+
+ git fetch --shallow-exclude=v6.0 origin
+
+ In case you want to access a stable/longterm release (say v6.1.5), simply add
+ the branch holding that series; afterwards fetch the history at least up to
+ the mainline version that started the series (v6.1)::
+
+ git remote set-branches --add origin linux-6.1.y
+ git fetch --shallow-exclude=v6.0 origin
+
+ Now checkout the code you are interested in. If you just performed the
+ initial clone, you will be able to check out a fresh mainline codebase, which
+ is ideal for checking whether developers already fixed an issue::
+
+ git checkout --detach origin/master
+
+ If you deepened your clone, you instead of ``origin/master`` can specify the
+ version you deepened to (``v6.0`` above); later releases like ``v6.1`` and
+ pre-release like ``v6.2-rc1`` will work, too. Stable or longterm versions
+ like ``v6.1.5`` work just the same, if you added the appropriate
+ stable/longterm branch as described.
+
+ [:ref:`details<sources>`]
+
+.. _patching_sbs:
+
+ * In case you want to apply a kernel patch, do so now. Often a command like
+ this will do the trick::
+
+ patch -p1 < ../proposed-fix.patch
+
+ If the ``-p1`` is actually needed, depends on how the patch was created; in
+ case it does not apply thus try without it.
+
+ If you cloned the sources with git and anything goes sideways, run ``git
+ reset --hard`` to undo any changes to the sources.
+
+ [:ref:`details<patching>`]
+
+.. _tagging_sbs:
+
+ * If you patched your kernel or have one of the same version installed already,
+ better add a unique tag to the one you are about to build::
+
+ echo "-proposed_fix" > localversion
+
+ Running ``uname -r`` under your kernel later will then print something like
+ '6.1-rc4-proposed_fix'.
+
+ [:ref:`details<tagging>`]
+
+ .. _configuration_sbs:
+
+ * Create the build configuration for your kernel based on an existing
+ configuration.
+
+ If you already prepared such a '.config' file yourself, copy it to
+ ~/linux/ and run ``make olddefconfig``.
+
+ Use the same command, if your distribution or somebody else already tailored
+ your running kernel to your or your hardware's needs: the make target
+ 'olddefconfig' will then try to use that kernel's .config as base.
+
+ Using this make target is fine for everybody else, too -- but you often can
+ save a lot of time by using this command instead::
+
+ yes "" | make localmodconfig
+
+ This will try to pick your distribution's kernel as base, but then disable
+ modules for any features apparently superfluous for your setup. This will
+ reduce the compile time enormously, especially if you are running an
+ universal kernel from a commodity Linux distribution.
+
+ There is a catch: 'localmodconfig' is likely to disable kernel features you
+ did not use since you booted your Linux -- like drivers for currently
+ disconnected peripherals or a virtualization software not haven't used yet.
+ You can reduce or nearly eliminate that risk with tricks the reference
+ section outlines; but when building a kernel just for quick testing purposes
+ it is often negligible if such features are missing. But you should keep that
+ aspect in mind when using a kernel built with this make target, as it might
+ be the reason why something you only use occasionally stopped working.
+
+ [:ref:`details<configuration>`]
+
+.. _configmods_sbs:
+
+ * Check if you might want to or have to adjust some kernel configuration
+ options:
+
+ * Evaluate how you want to handle debug symbols. Enable them, if you later
+ might need to decode a stack trace found for example in a 'panic', 'Oops',
+ 'warning', or 'BUG'; on the other hand disable them, if you are short on
+ storage space or prefer a smaller kernel binary. See the reference section
+ for details on how to do either. If neither applies, it will likely be fine
+ to simply not bother with this. [:ref:`details<configmods_debugsymbols>`]
+
+ * Are you running Debian? Then to avoid known problems by performing
+ additional adjustments explained in the reference section.
+ [:ref:`details<configmods_distros>`].
+
+ * If you want to influence the other aspects of the configuration, do so now
+ by using make targets like 'menuconfig' or 'xconfig'.
+ [:ref:`details<configmods_individual>`].
+
+.. _build_sbs:
+
+ * Build the image and the modules of your kernel::
+
+ make -j $(nproc --all)
+
+ If you want your kernel packaged up as deb, rpm, or tar file, see the
+ reference section for alternatives.
+
+ [:ref:`details<build>`]
+
+.. _install_sbs:
+
+ * Now install your kernel::
+
+ command -v installkernel && sudo make modules_install install
+
+ Often all left for you to do afterwards is a ``reboot``, as many commodity
+ Linux distributions will then create an initramfs (also known as initrd) and
+ an entry for your kernel in your bootloader's configuration; but on some
+ distributions you have to take care of these two steps manually for reasons
+ the reference section explains.
+
+ On a few distributions like Arch Linux and its derivatives the above command
+ does nothing at all; in that case you have to manually install your kernel,
+ as outlined in the reference section.
+
+ If you are running an immutable Linux distribution, check its documentation
+ and the web to find out how to install your own kernel there.
+
+ [:ref:`details<install>`]
+
+.. _another_sbs:
+
+ * To later build another kernel you need similar steps, but sometimes slightly
+ different commands.
+
+ First, switch back into the sources tree::
+
+ cd ~/linux/
+
+ In case you want to build a version from a stable/longterm series you have
+ not used yet (say 6.2.y), tell git to track it::
+
+ git remote set-branches --add origin linux-6.2.y
+
+ Now fetch the latest upstream changes; you again need to specify the earliest
+ version you care about, as git otherwise might retrieve the entire commit
+ history::
+
+ git fetch --shallow-exclude=v6.0 origin
+
+ Now switch to the version you are interested in -- but be aware the command
+ used here will discard any modifications you performed, as they would
+ conflict with the sources you want to checkout::
+
+ git checkout --force --detach origin/master
+
+ At this point you might want to patch the sources again or set/modify a build
+ tag, as explained earlier. Afterwards adjust the build configuration to the
+ new codebase using olddefconfig, which will now adjust the configuration file
+ you prepared earlier using localmodconfig (~/linux/.config) for your next
+ kernel::
+
+ # reminder: if you want to apply patches, do it at this point
+ # reminder: you might want to update your build tag at this point
+ make olddefconfig
+
+ Now build your kernel::
+
+ make -j $(nproc --all)
+
+ Afterwards install the kernel as outlined above::
+
+ command -v installkernel && sudo make modules_install install
+
+ [:ref:`details<another>`]
+
+.. _uninstall_sbs:
+
+ * Your kernel is easy to remove later, as its parts are only stored in two
+ places and clearly identifiable by the kernel's release name. Just ensure to
+ not delete the kernel you are running, as that might render your system
+ unbootable.
+
+ Start by deleting the directory holding your kernel's modules, which is named
+ after its release name -- '6.0.1-foobar' in the following example::
+
+ sudo rm -rf /lib/modules/6.0.1-foobar
+
+ Now try the following command, which on some distributions will delete all
+ other kernel files installed while also removing the kernel's entry from the
+ bootloader configuration::
+
+ command -v kernel-install && sudo kernel-install -v remove 6.0.1-foobar
+
+ If that command does not output anything or fails, see the reference section;
+ do the same if any files named '*6.0.1-foobar*' remain in /boot/.
+
+ [:ref:`details<uninstall>`]
+
+.. _submit_improvements_qbtl:
+
+Did you run into trouble following any of the above steps that is not cleared up
+by the reference section below? Or do you have ideas how to improve the text?
+Then please take a moment of your time and let the maintainer of this document
+know by email (Thorsten Leemhuis <linux@leemhuis.info>), ideally while CCing the

+
+Reference section for the step-by-step guide
+============================================
+
+This section holds additional information for each of the steps in the above
+guide.
+
+.. _backup:
+
+Prepare for emergencies
+-----------------------
+
+ *Create a fresh backup and put system repair and restore tools at hand*
+ [:ref:`... <backup_sbs>`]
+
+Remember, you are dealing with computers, which sometimes do unexpected things
+-- especially if you fiddle with crucial parts like the kernel of an operating
+system. That's what you are about to do in this process. Hence, better prepare
+for something going sideways, even if that should not happen.
+
+[:ref:`back to step-by-step guide <backup_sbs>`]
+
+.. _secureboot:
+
+Dealing with techniques like Secure Boot
+----------------------------------------
+
+ *On platforms with 'Secure Boot' or similar techniques, prepare everything to
+ ensure the system will permit your self-compiled kernel to boot later.*
+ [:ref:`... <secureboot_sbs>`]
+
+Many modern systems allow only certain operating systems to start; they thus by
+default will reject booting self-compiled kernels.
+
+You ideally deal with this by making your platform trust your self-built kernels
+with the help of a certificate and signing. How to do that is not described
+here, as it requires various steps that would take the text too far away from
+its purpose; 'Documentation/admin-guide/module-signing.rst' and various web
+sides already explain this in more detail.
+
+Temporarily disabling solutions like Secure Boot is another way to make your own
+Linux boot. On commodity x86 systems it is possible to do this in the BIOS Setup
+utility; the steps to do so are not described here, as they greatly vary between
+machines.
+
+On mainstream x86 Linux distributions there is a third and universal option:
+disable all Secure Boot restrictions for your Linux environment. You can
+initiate this process by running ``mokutil --disable-validation``; this will
+tell you to create a one-time password, which is safe to write down. Now
+restart; right after your BIOS performed all self-tests the bootloader Shim will
+show a blue box with a message 'Press any key to perform MOK management'. Hit
+some key before the countdown exposes. This will open a menu and choose 'Change
+Secure Boot state' there. Shim's 'MokManager' will now ask you to enter three
+randomly chosen characters from the one-time password specified earlier. Once
+you provided them, confirm that you really want to disable the validation.
+Afterwards, permit MokManager to reboot the machine.
+
+[:ref:`back to step-by-step guide <secureboot_sbs>`]
+
+.. _buildrequires:
+
+Install build requirements
+--------------------------
+
+ *Install all software required to build a Linux kernel.*
+ [:ref:`...<buildrequires_sbs>`]
+
+The kernel is pretty stand-alone, but besides tools like the compiler you will
+sometimes need a few libraries to build one. How to install everything needed
+depends on your Linux distribution and the configuration of the kernel you are
+about to build.
+
+Here are a few examples what you typically need on some mainstream
+distributions:
+
+ * Debian, Ubuntu, and derivatives::
+
+ sudo apt install bc binutils bison dwarves flex gcc git make openssl \
+ pahole perl-base libssl-dev libelf-dev
+
+ * Fedora and derivatives::
+
+ sudo dnf install binutils /usr/include/{libelf.h,openssl/pkcs7.h} \
+ /usr/bin/{bc,bison,flex,gcc,git,openssl,make,perl,pahole}
+
+ * openSUSE and derivatives::
+
+ sudo zypper install bc binutils bison dwarves flex gcc git make perl-base \
+ openssl openssl-devel libelf-dev
+
+In case you wonder why these lists include openssl and its development headers:
+they are needed for the Secure Boot support, which many distributions enable in
+their kernel configuration for x86 machines.
+
+Sometimes you will need tools for compression formats like bzip2, gzip, lz4,
+lzma, lzo, xz, or zstd as well.
+
+You might need additional libraries and their development headers in case you
+perform tasks not covered in this guide. For example, zlib will be needed when
+building kernel tools from the tools/ directory; adjusting the build
+configuration with make targets like 'menuconfig' or 'xconfig' will require
+development headers for ncurses or Qt5.
+
+[:ref:`back to step-by-step guide <buildrequires_sbs>`]
+
+.. _diskspace:
+
+Space requirements
+------------------
+
+ *Ensure to have enough free space for building and installing Linux.*
+ [:ref:`... <diskspace_sbs>`]
+
+The numbers mentioned are rough estimates with a big extra charge to be on the
+safe side, so often you will need less.
+
+If you have space constraints, remember to read the reference section when you
+reach the :ref:`section about configuration adjustments' <configmods>`, as
+ensuring debug symbols are disabled will reduce the consumed disk space by quite
+a few gigabytes.
+
+[:ref:`back to step-by-step guide <diskspace_sbs>`]
+
+
+.. _sources:
+
+Download the sources
+--------------------
+
+ *Retrieve the sources of the Linux version you intend to build.*
+ [:ref:`...<sources_sbs>`]
+
+The step-by-step guide outlines how to retrieve Linux' sources using a shallow
+git clone. There is :ref:`more to tell about this method<sources_shallow>` and
+two alternate ways worth describing: :ref:`packaged archives<sources_archive>`
+and :ref:`a full git clone<sources_full>`. And the aspects ':ref:`wouldn't it
+be wiser to use a proper pre-release than the latest mainline code
+<sources_snapshot>`' and ':ref:`how to get an even fresher mainline codebase
+<sources_fresher>`' need elaboration, too.
+
+Note, to keep things simple the commands used in this guide store the build
+artifacts in the source tree. If you prefer to separate them, simply add
+something like ``O=~/linux-builddir/`` to all make calls; also adjust the path
+in all commands that add files or modify any generated (like your '.config').
+
+[:ref:`back to step-by-step guide <sources_sbs>`]
+
+.. _sources_shallow:
+
+Noteworthy characteristics of shallow clones
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The step-by-step guide uses a shallow clone, as it is the best solution for most
+of this document's target audience. There are a few aspects of this approach
+worth mentioning:
+
+ * This document in most places uses ``git fetch`` with ``--shallow-exclude=``
+ to specify the earliest version you care about (or to be precise: its git
+ tag). You alternatively can use the parameter ``--shallow-since=`` to specify
+ an absolute (say ``'2023-07-15'``) or relative (``'12 months'``) date to
+ define the depth of the history you want to download. As a second
+ alternative, you can also specify a certain depth explicitly with a parameter
+ like ``--depth=1``, unless you add branches for stable/longterm kernels.
+
+ * When running ``git fetch``, remember to always specify the oldest version,
+ the time you care about, or an explicit depth as shown in the step-by-step
+ guide. Otherwise you will risk downloading nearly the entire git history,
+ which will consume quite a bit of time and bandwidth while also stressing the
+ servers.
+
+ Note, you do not have to use the same version or date all the time. But when
+ you change it over time, git will deepen or flatten the history to the
+ specified point. That allows you to retrieve versions you initially thought
+ you did not need -- or it will discard the sources of older versions, for
+ example in case you want to free up some disk space. The latter will happen
+ automatically when using ``--shallow-since=`` or
+ ``--depth=``.
+
+ * Be warned, when deepening your clone you might encounter an error like
+ 'fatal: error in object: unshallow cafecaca0c0dacafecaca0c0dacafecaca0c0da'.
+ In that case run ``git repack -d`` and try again``
+
+ * In case you want to revert changes from a certain version (say Linux 6.3) or
+ perform a bisection (v6.2..v6.3), better tell ``git fetch`` to retrieve
+ objects up to three versions earlier (e.g. 6.0): ``git describe`` will then
+ be able to describe most commits just like it would in a full git clone.
+
+[:ref:`back to step-by-step guide <sources_sbs>`] [:ref:`back to section intro <sources>`]
+
+.. _sources_archive:
+
+Downloading the sources using a packages archive
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+People new to compiling Linux often assume downloading an archive via the
+front-page of https://kernel.org is the best approach to retrieve Linux'
+sources. It actually can be, if you are certain to build just one particular
+kernel version without changing any code. Thing is: you might be sure this will
+be the case, but in practice it often will turn out to be a wrong assumption.
+
+That's because when reporting or debugging an issue developers will often ask to
+give another version a try. They also might suggest temporarily undoing a commit
+with ``git revert`` or might provide various patches to try. Sometimes reporters
+will also be asked to use ``git bisect`` to find the change causing a problem.
+These things rely on git or are a lot easier and quicker to handle with it.
+
+A shallow clone also does not add any significant overhead. For example, when
+you use ``git clone --depth=1`` to create a shallow clone of the latest mainline
+codebase git will only retrieve a little more data than downloading the latest
+mainline pre-release (aka 'rc') via the front-page of kernel.org would.
+
+A shallow clone therefore is often the better choice. If you nevertheless want
+to use a packaged source archive, download one via kernel.org; afterwards
+extract its content to some directory and change to the subdirectory created
+during extraction. The rest of the step-by-step guide will work just fine, apart
+from things that rely on git -- but this mainly concerns the section on
+successive builds of other versions.
+
+[:ref:`back to step-by-step guide <sources_sbs>`] [:ref:`back to section intro <sources>`]
+
+.. _sources_full:
+
+Downloading the sources using a full git clone
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If downloading and storing a lot of data (~4,4 Gigabyte as of early 2023) is
+nothing that bothers you, instead of a shallow clone perform a full git clone
+instead. You then will avoid the specialties mentioned above and will have all
+versions and individual commits at hand at any time::
+
+ curl -L \
+ https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/clone.bundle \
+ -o linux-stable.git.bundle
+ git clone linux-stable.git.bundle ~/linux/
+ rm linux-stable.git.bundle
+ cd ~/linux/
+ git remote set-url origin \
+ https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
+ git fetch origin
+ git checkout --detach origin/master
+
+[:ref:`back to step-by-step guide <sources_sbs>`] [:ref:`back to section intro <sources>`]
+
+.. _sources_snapshot:
+
+Proper pre-releases (RCs) vs. latest mainline
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When cloning the sources using git and checking out origin/master, you often
+will retrieve a codebase that is somewhere between the latest and the next
+release or pre-release. This almost always is the code you want when giving
+mainline a shot: pre-releases like v6.1-rc5 are in no way special, as they do
+not get any significant extra testing before being published.
+
+There is one exception: you might want to stick to the latest mainline release
+(say v6.1) before its successor's first pre-release (v6.2-rc1) is out. That is
+because compiler errors and other problems are more likely to occur during this
+time, as mainline then is in its 'merge window': a usually two week long phase,
+in which the bulk of the changes for the next release is merged.
+
+[:ref:`back to step-by-step guide <sources_sbs>`] [:ref:`back to section intro <sources>`]
+
+.. _sources_fresher:
+
+Avoiding the mainline lag
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The explanations for both the shallow clone and the full clone both retrieve the
+code from the Linux stable git repository. That makes things simpler for this
+document's audience, as it allows easy access to both mainline and
+stable/longterm releases. This approach has just one downside:
+
+Changes merged into the mainline repository are only synced to the master branch
+of the Linux stable repository every few hours. This lag most of the time is
+not something to worry about; but in case you really need the latest code, just
+add the mainline repo as additional remote and checkout the code from there::
+
+ git remote add mainline \
+ https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
+ git fetch mainline
+ git checkout --detach mainline/master
+
+When doing this with a shallow clone, remember to call ``git fetch`` with one
+of the parameters described earlier to limit the depth.
+
+[:ref:`back to step-by-step guide <sources_sbs>`] [:ref:`back to section intro <sources>`]
+
+.. _patching:
+
+Patch the sources (optional)
+----------------------------
+
+ *In case you want to apply a kernel patch, do so now.*
+ [:ref:`...<patching_sbs>`]
+
+This is the point where you might want to patch your kernel -- for example when
+a developer proposed a fix and asked you to check if it helps. The step-by-step
+guide already explains everything crucial here.
+
+[:ref:`back to step-by-step guide <patching_sbs>`]
+
+.. _tagging:
+
+Tagging this kernel build (optional, often wise)
+------------------------------------------------
+
+ *If you patched your kernel or already have that kernel version installed,
+ better tag your kernel by extending its release name:*
+ [:ref:`...<tagging_sbs>`]
+
+Tagging your kernel will help avoid confusion later, especially when you patched
+your kernel. Adding an individual tag will also ensure the kernel's image and
+its modules are installed in parallel to any existing kernels.
+
+There are various ways to add such a tag. The step-by-step guide realizes one by
+creating a 'localversion' file in your build directory from which the kernel
+build scripts will automatically pick up the tag. You can later change that file
+to use a different tag in subsequent builds or simply remove that file to dump
+the tag.
+
+[:ref:`back to step-by-step guide <tagging_sbs>`]
+
+.. _configuration:
+
+Define the build configuration for your kernel
+----------------------------------------------
+
+ *Create the build configuration for your kernel based on an existing
+ configuration.* [:ref:`... <configuration_sbs>`]
+
+There are various aspects for this steps that require a more careful
+explanation:
+
+Pitfalls when using another configuration file as base
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Make targets like localmodconfig and olddefconfig share a few common snares you
+want to be aware of:
+
+ * These targets will reuse a kernel build configuration in your build directory
+ (e.g. '~/linux/.config'), if one exists. In case you want to start from
+ scratch you thus need to delete it.
+
+ * The make targets try to find the configuration for your running kernel
+ automatically, but might choose poorly. A line like '# using defaults found
+ in /boot/config-6.0.7-250.fc36.x86_64' or 'using config:
+ '/boot/config-6.0.7-250.fc36.x86_64' tells you which file they picked. If
+ that is not the intended one, simply store it as '~/linux/.config'
+ before using these make targets.
+
+ * Unexpected things might happen if you try to use a config file prepared for
+ one kernel (say v6.0) on an older generation (say v5.15). In that case you
+ might want to use a configuration as base which your distribution utilized
+ when they used that or an slightly older kernel version.
+
+Influencing the configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The make target olddefconfig and the ``yes "" |`` used when utilizing
+localmodconfig will set any undefined build options to their default value. This
+among others will disable many kernel features that were introduced after your
+base kernel was released.
+
+If you want to set these configurations options manually, use ``oldconfig``
+instead of ``olddefconfig`` or omit the ``yes "" |`` when utilizing
+localmodconfig. Then for each undefined configuration option you will be asked
+how to proceed. In case you are unsure what to answer, simply hit 'enter' to
+apply the default value.
+
+Big pitfall when using localmodconfig
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As explained briefly in the step-by-step guide already: with localmodconfig it
+can easily happen that your self-built kernel will lack modules for tasks you
+did not perform before utilizing this make target. That's because those tasks
+require kernel modules that are normally autoloaded when you perform that task
+for the first time; if you didn't perform that task at least once before using
+localmodconfig, the latter will thus assume these modules are superfluous and
+disable them.
+
+You can try to avoid this by performing typical tasks that often will autoload
+additional kernel modules: start a VM, establish VPN connections, loop-mount a
+CD/DVD ISO, mount network shares (CIFS, NFS, ...), and connect all external
+devices (2FA keys, headsets, webcams, ...) as well as storage devices with file
+systems you otherwise do not utilize (btrfs, ext4, FAT, NTFS, XFS, ...). But it
+is hard to think of everything that might be needed -- even kernel developers
+often forget one thing or another at this point.
+
+Do not let that risk bother you, especially when compiling a kernel only for
+testing purposes: everything typically crucial will be there. And if you forget
+something important you can turn on a missing feature later and quickly run the
+commands to compile and install a better kernel.
+
+But if you plan to build and use self-built kernels regularly, you might want to
+reduce the risk by recording which modules your system loads over the course of
+a few weeks. You can automate this with `modprobed-db
+<https://github.com/graysky2/modprobed-db>`_. Afterwards use ``LSMOD=<path>`` to
+point localmodconfig to the list of modules modprobed-db noticed being used::
+
+ yes "" | make LSMOD="${HOME}"/.config/modprobed.db localmodconfig
+
+Remote building with localmodconfig
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to use localmodconfig to build a kernel for another machine, run
+``lsmod > lsmod_foo-machine`` on it and transfer that file to your build host.
+Now point the build scripts to the file like this: ``yes "" | make
+LSMOD=~/lsmod_foo-machine localmodconfig``. Note, in this case
+you likely want to copy a base kernel configuration from the other machine over
+as well and place it as .config in your build directory.
+
+[:ref:`back to step-by-step guide <configuration_sbs>`]
+
+.. _configmods:
+
+Adjust build configuration
+--------------------------
+
+ *Check if you might want to or have to adjust some kernel configuration
+ options:*
+
+Depending on your needs you at this point might want or have to adjust some
+kernel configuration options.
+
+.. _configmods_debugsymbols:
+
+Debug symbols
+~~~~~~~~~~~~~
+
+ *Evaluate how you want to handle debug symbols.*
+ [:ref:`...<configmods_sbs>`]
+
+Most users do not need to care about this, it's often fine to leave everything
+as it is; but you should take a closer look at this, if you might need to decode
+a stack trace or want to reduce space consumption.
+
+Having debug symbols available can be important when your kernel throws a
+'panic', 'Oops', 'warning', or 'BUG' later when running, as then you will be
+able to find the exact place where the problem occurred in the code. But
+collecting and embedding the needed debug information takes time and consumes
+quite a bit of space: in late 2022 the build artifacts for a typical x86 kernel
+configured with localmodconfig consumed around 5 Gigabyte of space with debug
+symbols, but less than 1 when they were disabled. The resulting kernel image and
+the modules are bigger as well, which increases load times.
+
+Hence, if you want a small kernel and are unlikely to decode a stack trace
+later, you might want to disable debug symbols to avoid above downsides::
+
+ ./scripts/config --file .config -d DEBUG_INFO \
+ -d DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT -d DEBUG_INFO_DWARF4 \
+ -d DEBUG_INFO_DWARF5 -e CONFIG_DEBUG_INFO_NONE
+ make olddefconfig
+
+You on the other hand definitely want to enable them, if there is a decent
+chance that you need to decode a stack trace later (as explained by 'Decode
+failure messages' in Documentation/admin-guide/tainted-kernels.rst in more
+detail)::
+
+ ./scripts/config --file .config -d DEBUG_INFO_NONE -e DEBUG_KERNEL
+ -e DEBUG_INFO -e DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT -e KALLSYMS -e KALLSYMS_ALL
+ make olddefconfig
+
+Note, many mainstream distributions enable debug symbols in their kernel
+configurations -- make targets like localmodconfig and olddefconfig thus will
+often pick that setting up.

+~~~~~~~~~~~~~~~~~~~~~~
+
+ *If you want to influence the other aspects of the configuration, do so

+You at this point can use a command like ``make menuconfig`` to enable or
+disable certain features using a text-based user interface; to use a graphical
+configuration utilize, use the make target ``xconfig`` or ``gconfig`` instead.
+All of them require development libraries from toolkits they are based on

+
+.. _build:
+
+Build your kernel
+-----------------
+
+ *Build the image and the modules of your kernel* [:ref:`... <build_sbs>`]
+
+A lot can go wrong at this stage, but the instructions below will help you help
+yourself. Another subsection explains how to directly package your kernel up as
+deb, rpm or tar file.
+
+Dealing with build errors
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When a build error occurs, it might be caused by some aspect of your machine's
+setup that often can be fixed quickly; other times though the problem lies in
+the code and can only be fixed by a developer. A close examination of the
+failure messages coupled with some research on the internet will often tell you
+which of the two it is. To perform such an investigation, restart the build
+process like this::
+
+ make V=1
+
+The ``V=1`` activates verbose output, which might be needed to see the actual
+error. To make it easier to spot, this command also omits the ``-j $(nproc
+--all)`` used earlier to utilize every CPU core in the system for the job -- but
+this parallelism also results in some clutter when failures occur.
+
+After a few seconds the build process should run into the error again. Now try
+to find the most crucial line describing the problem. Then search the internet
+for the most important and non-generic section of that line (say 4 to 8 words);
+avoid or remove anything that looks remotely system-specific, like your username
+or local path names like ``/home/username/linux/``. First try your regular
+internet search engine with that string, afterwards search Linux kernel mailing
+lists via `lore.kernel.org/all/ <https://lore.kernel.org/all/>`_.
+
+This most of the time will find something that will explain what is wrong; quite
+often one of the hits will provide a solution for your problem, too. If you
+do not find anything that matches your problem, try again from a different angle
+by modifying your search terms or using another line from the error messages.
+
+In the end, most trouble you are to run into has likely been encountered and
+reported by others already. That includes issues where the cause is not your
+system, but lies the code. If you run into one of those, you might thus find a
+solution (e.g. a patch) or workaround for your problem, too.
+
+Package your kernel up
+~~~~~~~~~~~~~~~~~~~~~~
+
+The step-by-step guide uses the default make targets (e.g. 'bzImage' and
+'modules' on x86) to build the image and the modules of your kernel, which later
+steps of the guide then install. You instead can also directly build everything
+and directly package it up by using one of the following targets:
+
+ * ``make -j $(nproc --all) bindeb-pkg`` to generate a deb package
+
+ * ``make -j $(nproc --all) binrpm-pkg`` to generate a rpm package
+
+ * ``make -j $(nproc --all) tarbz2-pkg`` to generate a bz2 compressed tarball
+
+This is just a selection of available make targets for this purpose, see
+``make help`` for others. You can also use these targets after running
+``make -j $(nproc --all)``, as they will pick up everything already built.
+
+If you employ the targets to generate deb or rpm packages, ignore the
+step-by-step guide's instructions on installing and removing your kernel;
+instead install and remove the packages using the package utility for the format
+(e.g. dpkg and rpm) or a package management utility build on top of them (apt,
+aptitude, dnf/yum, zypper, ...). Be aware that the packages generated using
+these two make targets are designed to work on various distributions utilizing
+those formats, they thus will sometimes behave differently than your
+distribution's kernel packages.
+
+[:ref:`back to step-by-step guide <build_sbs>`]
+
+.. _install:
+
+Install your kernel
+-------------------
+
+ *Now install your kernel* [:ref:`... <install_sbs>`]
+
+What you need to do after executing the command in the step-by-step guide
+depends on the existence and the implementation of an ``installkernel``
+executable. Many commodity Linux distributions ship such a kernel installer in
+``/sbin/`` that does everything needed, hence there is nothing left for you
+except rebooting. But some distributions contain an installkernel that does
+only part of the job -- and a few lack it completely and leave all the work to
+you.
+
+If ``installkernel`` is found, the kernel's build system will delegate the
+actual installation of your kernel's image and related files to this executable.
+On almost all Linux distributions it will store the image as '/boot/vmlinuz-
+<your kernel's release name>' and put a 'System.map-<your kernel's release
+name>' alongside it. Your kernel will thus be installed in parallel to any
+existing ones, unless you already have one with exactly the same release name.
+
+Installkernel on many distributions will afterwards generate an 'initramfs'
+(often also called 'initrd'), which commodity distributions rely on for booting;
+hence be sure to keep the order of the two make targets used in the step-by-step
+guide, as things will go sideways if you install your kernel's image before its
+modules. Often installkernel will then add your kernel to the bootloader
+configuration, too. You have to take care of one or both of these tasks
+yourself, if your distributions installkernel doesn't handle them.
+
+A few distributions like Arch Linux and its derivatives totally lack an
+installkernel executable. On those just install the modules using the kernel's
+build system and then install the image and the System.map file manually::
+
+ sudo make modules_install
+ sudo install -m 0600 $(make -s image_name) /boot/vmlinuz-$(make -s kernelrelease)
+ sudo install -m 0600 System.map /boot/System.map-$(make -s kernelrelease)
+
+If your distribution boots with the help of an initramfs, now generate one for
+your kernel using the tools your distribution provides for this process.
+Afterwards add your kernel to your bootloader configuration and reboot.
+
+[:ref:`back to step-by-step guide <install_sbs>`]
+
+.. _another:
+
+Another round later
+-------------------
+
+ *To later build another kernel you need similar, but sometimes slightly
+ different commands* [:ref:`... <another_sbs>`]
+
+The process to build later kernels is similar, but at some points slightly
+different. You for example do not want to use 'localmodconfig' for succeeding
+kernel builds, as you already created a trimmed down configuration you want to
+use from now on. Hence instead just use ``oldconfig`` or ``olddefconfig`` to
+adjust your build configurations to the needs of the kernel version you are
+about to build.
+
+If you created a shallow-clone with git, remember what the :ref:`section that
+explained the setup described in more detail <sources>`: you need to use a
+slightly different ``git fetch`` command and when switching to another series
+need to add an additional remote branch.
+
+[:ref:`back to step-by-step guide <another_sbs>`]
+
+.. _uninstall:
+
+Uninstall the kernel later
+--------------------------
+
+ *All parts of your installed kernel are identifiable by its release name and
+ thus easy to remove later.* [:ref:`... <uninstall_sbs>`]
+
+Do not worry installing your kernel manually and thus bypassing your
+distribution's packaging system will totally mess up your machine: all parts of
+your kernel are easy to remove later, as files are stored in two places only and
+normally identifiable by the kernel's release name.
+
+One of the two places is a directory in /lib/modules/, which holds the modules
+for each installed kernel. This directory is named after the kernel's release
+name; hence, to remove all modules for one of your kernels, simply remove its
+modules directory in /lib/modules/.
+
+The other place is /boot/, where typically one to five files will be placed
+during installation of a kernel. All of them usually contain the release name in
+their file name, but how many files and their name depends somewhat on your
+distribution's installkernel executable (:ref:`see above <install>`) and its
+initramfs generator. On some distributions the ``kernel-install`` command
+mentioned in the step-by-step guide will remove all of these files for you --
+and the entry for your kernel in the bootloader configuration at the same time,
+too. On others you have to take care of these steps yourself. The following
+command should interactively remove the two main files of a kernel with the
+release name '6.0.1-foobar'::
+
+ rm -i /boot/{System.map,vmlinuz}-6.0.1-foobar
+
+Now remove the belonging initramfs, which often will be called something like
+``/boot/initramfs-6.0.1-foobar.img`` or ``/boot/initrd.img-6.0.1-foobar``.
+Afterwards check for other files in /boot/ that have '6.0.1-foobar' in their
+name and delete them as well. Now remove the kernel from your bootloader's
+configuration.
+
+Note, be very careful with wildcards like '*' when deleting files or directories
+for kernels manually: you might accidentally remove files of a 6.0.11 kernel
+when all you want is to remove 6.0 or 6.0.1.

+FAQ
+===
+
+Why does this 'how-to' not work on my system?

+
+As initially stated, this guide is 'designed to cover everything typically
+needed [to build a kernel] on mainstream Linux distributions running on
+commodity PC or server hardware'. The outlined approach despite this should work
+on many other setups as well. But trying to cover every possible use-case in one
+guide would defeat its purpose, as without such a focus you would need dozens or
+hundreds of constructs along the lines of 'in case you are having <insert

-Reliability, Availability and Serviceability
-============================================
-
-RAS concepts
-************
-
-Reliability, Availability and Serviceability (RAS) is a concept used on
-servers meant to measure their robustness.
-
-Reliability
- is the probability that a system will produce correct outputs.
-
- * Generally measured as Mean Time Between Failures (MTBF)
- * Enhanced by features that help to avoid, detect and repair hardware faults
-
-Availability
- is the probability that a system is operational at a given time
-
- * Generally measured as a percentage of downtime per a period of time
- * Often uses mechanisms to detect and correct hardware faults in
- runtime;
-
-Serviceability (or maintainability)
- is the simplicity and speed with which a system can be repaired or
- maintained
-
- * Generally measured on Mean Time Between Repair (MTBR)
-
-Improving RAS
--------------
-
-In order to reduce systems downtime, a system should be capable of detecting
-hardware errors, and, when possible correcting them in runtime. It should
-also provide mechanisms to detect hardware degradation, in order to warn
-the system administrator to take the action of replacing a component before
-it causes data loss or system downtime.
-
-Among the monitoring measures, the most usual ones include:
-
-* CPU – detect errors at instruction execution and at L1/L2/L3 caches;
-* Memory – add error correction logic (ECC) to detect and correct errors;
-* I/O – add CRC checksums for transferred data;
-* Storage – RAID, journal file systems, checksums,
- Self-Monitoring, Analysis and Reporting Technology (SMART).
-
-By monitoring the number of occurrences of error detections, it is possible
-to identify if the probability of hardware errors is increasing, and, on such
-case, do a preventive maintenance to replace a degraded component while
-those errors are correctable.
-
-Types of errors
----------------
-
-Most mechanisms used on modern systems use technologies like Hamming
-Codes that allow error correction when the number of errors on a bit packet
-is below a threshold. If the number of errors is above, those mechanisms
-can indicate with a high degree of confidence that an error happened, but
-they can't correct.
-
-Also, sometimes an error occur on a component that it is not used. For
-example, a part of the memory that it is not currently allocated.
-
-That defines some categories of errors:
-
-* **Correctable Error (CE)** - the error detection mechanism detected and
- corrected the error. Such errors are usually not fatal, although some
- Kernel mechanisms allow the system administrator to consider them as fatal.
-
-* **Uncorrected Error (UE)** - the amount of errors happened above the error
- correction threshold, and the system was unable to auto-correct.
-
-* **Fatal Error** - when an UE error happens on a critical component of the
- system (for example, a piece of the Kernel got corrupted by an UE), the
- only reliable way to avoid data corruption is to hang or reboot the machine.
-
-* **Non-fatal Error** - when an UE error happens on an unused component,
- like a CPU in power down state or an unused memory bank, the system may
- still run, eventually replacing the affected hardware by a hot spare,
- if available.
-
- Also, when an error happens on a userspace process, it is also possible to
- kill such process and let userspace restart it.
-
-The mechanism for handling non-fatal errors is usually complex and may
-require the help of some userspace application, in order to apply the
-policy desired by the system administrator.
-
-Identifying a bad hardware component
-------------------------------------
-
-Just detecting a hardware flaw is usually not enough, as the system needs
-to pinpoint to the minimal replaceable unit (MRU) that should be exchanged
-to make the hardware reliable again.
-
-So, it requires not only error logging facilities, but also mechanisms that
-will translate the error message to the silkscreen or component label for
-the MRU.
-
-Typically, it is very complex for memory, as modern CPUs interlace memory
-from different memory modules, in order to provide a better performance. The
-DMI BIOS usually have a list of memory module labels, with can be obtained
-using the ``dmidecode`` tool. For example, on a desktop machine, it shows::
-
- Memory Device
- Total Width: 64 bits
- Data Width: 64 bits
- Size: 16384 MB
- Form Factor: SODIMM
- Set: None
- Locator: ChannelA-DIMM0
- Bank Locator: BANK 0
- Type: DDR4
- Type Detail: Synchronous
- Speed: 2133 MHz
- Rank: 2
- Configured Clock Speed: 2133 MHz
-
-On the above example, a DDR4 SO-DIMM memory module is located at the
-system's memory labeled as "BANK 0", as given by the *bank locator* field.
-Please notice that, on such system, the *total width* is equal to the
-*data width*. It means that such memory module doesn't have error
-detection/correction mechanisms.
-
-Unfortunately, not all systems use the same field to specify the memory
-bank. On this example, from an older server, ``dmidecode`` shows::
-
- Memory Device
- Array Handle: 0x1000
- Error Information Handle: Not Provided
- Total Width: 72 bits
- Data Width: 64 bits
- Size: 8192 MB
- Form Factor: DIMM
- Set: 1
- Locator: DIMM_A1
- Bank Locator: Not Specified
- Type: DDR3
- Type Detail: Synchronous Registered (Buffered)
- Speed: 1600 MHz
- Rank: 2
- Configured Clock Speed: 1600 MHz
-
-There, the DDR3 RDIMM memory module is located at the system's memory labeled
-as "DIMM_A1", as given by the *locator* field. Please notice that this
-memory module has 64 bits of *data width* and 72 bits of *total width*. So,
-it has 8 extra bits to be used by error detection and correction mechanisms.
-Such kind of memory is called Error-correcting code memory (ECC memory).
-
-To make things even worse, it is not uncommon that systems with different
-labels on their system's board to use exactly the same BIOS, meaning that
-the labels provided by the BIOS won't match the real ones.
-
-ECC memory
-----------
-
-As mentioned in the previous section, ECC memory has extra bits to be
-used for error correction. In the above example, a memory module has
-64 bits of *data width*, and 72 bits of *total width*. The extra 8
-bits which are used for the error detection and correction mechanisms
-are referred to as the *syndrome*\ [#f1]_\ [#f2]_.
-
-So, when the cpu requests the memory controller to write a word with
-*data width*, the memory controller calculates the *syndrome* in real time,
-using Hamming code, or some other error correction code, like SECDED+,
-producing a code with *total width* size. Such code is then written
-on the memory modules.
-
-At read, the *total width* bits code is converted back, using the same
-ECC code used on write, producing a word with *data width* and a *syndrome*.
-The word with *data width* is sent to the CPU, even when errors happen.
-
-The memory controller also looks at the *syndrome* in order to check if
-there was an error, and if the ECC code was able to fix such error.
-If the error was corrected, a Corrected Error (CE) happened. If not, an
-Uncorrected Error (UE) happened.
-
-The information about the CE/UE errors is stored on some special registers
-at the memory controller and can be accessed by reading such registers,
-either by BIOS, by some special CPUs or by Linux EDAC driver. On x86 64
-bit CPUs, such errors can also be retrieved via the Machine Check
-Architecture (MCA)\ [#f3]_.
-
-.. [#f1] Please notice that several memory controllers allow operation on a
- mode called "Lock-Step", where it groups two memory modules together,
- doing 128-bit reads/writes. That gives 16 bits for error correction, with
- significantly improves the error correction mechanism, at the expense
- that, when an error happens, there's no way to know what memory module is
- to blame. So, it has to blame both memory modules.
-
-.. [#f2] Some memory controllers also allow using memory in mirror mode.
- On such mode, the same data is written to two memory modules. At read,
- the system checks both memory modules, in order to check if both provide
- identical data. On such configuration, when an error happens, there's no
- way to know what memory module is to blame. So, it has to blame both
- memory modules (or 4 memory modules, if the system is also on Lock-step
- mode).
-
-.. [#f3] For more details about the Machine Check Architecture (MCA),
- please read Documentation/x86/x86_64/machinecheck.rst at the Kernel tree.

-EDAC - Error Detection And Correction
-*************************************
-
-.. note::
-
- "bluesmoke" was the name for this device driver subsystem when it
- was "out-of-tree" and maintained at http://bluesmoke.sourceforge.net.
- That site is mostly archaic now and can be used only for historical
- purposes.
-
- When the subsystem was pushed upstream for the first time, on
- Kernel 2.6.16, it was renamed to ``EDAC``.
-
-Purpose
--------
-
-The ``edac`` kernel module's goal is to detect and report hardware errors
-that occur within the computer system running under linux.
-
-Memory
-------
-
-Memory Correctable Errors (CE) and Uncorrectable Errors (UE) are the
-primary errors being harvested. These types of errors are harvested by
-the ``edac_mc`` device.
-
-Detecting CE events, then harvesting those events and reporting them,
-**can** but must not necessarily be a predictor of future UE events. With
-CE events only, the system can and will continue to operate as no data
-has been damaged yet.
-
-However, preventive maintenance and proactive part replacement of memory
-modules exhibiting CEs can reduce the likelihood of the dreaded UE events
-and system panics.
-
-Other hardware elements
------------------------
-
-A new feature for EDAC, the ``edac_device`` class of device, was added in
-the 2.6.23 version of the kernel.
-
-This new device type allows for non-memory type of ECC hardware detectors
-to have their states harvested and presented to userspace via the sysfs
-interface.
-
-Some architectures have ECC detectors for L1, L2 and L3 caches,
-along with DMA engines, fabric switches, main data path switches,
-interconnections, and various other hardware data paths. If the hardware
-reports it, then a edac_device device probably can be constructed to
-harvest and present that to userspace.
-
-
-PCI bus scanning
-----------------
-
-In addition, PCI devices are scanned for PCI Bus Parity and SERR Errors
-in order to determine if errors are occurring during data transfers.
-
-The presence of PCI Parity errors must be examined with a grain of salt.
-There are several add-in adapters that do **not** follow the PCI specification
-with regards to Parity generation and reporting. The specification says
-the vendor should tie the parity status bits to 0 if they do not intend
-to generate parity. Some vendors do not do this, and thus the parity bit
-can "float" giving false positives.
-
-There is a PCI device attribute located in sysfs that is checked by
-the EDAC PCI scanning code. If that attribute is set, PCI parity/error
-scanning is skipped for that device. The attribute is::
-
- broken_parity_status
-
-and is located in ``/sys/devices/pci<XXX>/0000:XX:YY.Z`` directories for
-PCI devices.
-
-
-Versioning
-----------
-
-EDAC is composed of a "core" module (``edac_core.ko``) and several Memory
-Controller (MC) driver modules. On a given system, the CORE is loaded
-and one MC driver will be loaded. Both the CORE and the MC driver (or
-``edac_device`` driver) have individual versions that reflect current
-release level of their respective modules.
-
-Thus, to "report" on what version a system is running, one must report
-both the CORE's and the MC driver's versions.
-
-
-Loading
--------
-
-If ``edac`` was statically linked with the kernel then no loading
-is necessary. If ``edac`` was built as modules then simply modprobe
-the ``edac`` pieces that you need. You should be able to modprobe
-hardware-specific modules and have the dependencies load the necessary
-core modules.
-
-Example::
-
- $ modprobe amd76x_edac
-
-loads both the ``amd76x_edac.ko`` memory controller module and the
-``edac_mc.ko`` core module.
-
-
-Sysfs interface
----------------
-
-EDAC presents a ``sysfs`` interface for control and reporting purposes. It
-lives in the /sys/devices/system/edac directory.
-
-Within this directory there currently reside 2 components:

-Memory Controller (mc) Model
-----------------------------
-
-Each ``mc`` device controls a set of memory modules [#f4]_. These modules
-are laid out in a Chip-Select Row (``csrowX``) and Channel table (``chX``).
-There can be multiple csrows and multiple channels.
-
-.. [#f4] Nowadays, the term DIMM (Dual In-line Memory Module) is widely
- used to refer to a memory module, although there are other memory
- packaging alternatives, like SO-DIMM, SIMM, etc. The UEFI
- specification (Version 2.7) defines a memory module in the Common
- Platform Error Record (CPER) section to be an SMBIOS Memory Device
- (Type 17). Along this document, and inside the EDAC subsystem, the term
- "dimm" is used for all memory modules, even when they use a
- different kind of packaging.
-
-Memory controllers allow for several csrows, with 8 csrows being a
-typical value. Yet, the actual number of csrows depends on the layout of
-a given motherboard, memory controller and memory module characteristics.
-
-Dual channels allow for dual data length (e. g. 128 bits, on 64 bit systems)
-data transfers to/from the CPU from/to memory. Some newer chipsets allow
-for more than 2 channels, like Fully Buffered DIMMs (FB-DIMMs) memory
-controllers. The following example will assume 2 channels:
-
- +------------+-----------------------+
- | CS Rows | Channels |
- +------------+-----------+-----------+
- | | ``ch0`` | ``ch1`` |
- +============+===========+===========+
- | |**DIMM_A0**|**DIMM_B0**|
- +------------+-----------+-----------+
- | ``csrow0`` | rank0 | rank0 |
- +------------+-----------+-----------+
- | ``csrow1`` | rank1 | rank1 |
- +------------+-----------+-----------+
- | |**DIMM_A1**|**DIMM_B1**|
- +------------+-----------+-----------+
- | ``csrow2`` | rank0 | rank0 |
- +------------+-----------+-----------+
- | ``csrow3`` | rank1 | rank1 |
- +------------+-----------+-----------+
-
-In the above example, there are 4 physical slots on the motherboard
-for memory DIMMs:
-
- +---------+---------+
- | DIMM_A0 | DIMM_B0 |
- +---------+---------+
- | DIMM_A1 | DIMM_B1 |
- +---------+---------+
-
-Labels for these slots are usually silk-screened on the motherboard.
-Slots labeled ``A`` are channel 0 in this example. Slots labeled ``B`` are
-channel 1. Notice that there are two csrows possible on a physical DIMM.
-These csrows are allocated their csrow assignment based on the slot into
-which the memory DIMM is placed. Thus, when 1 DIMM is placed in each
-Channel, the csrows cross both DIMMs.
-
-Memory DIMMs come single or dual "ranked". A rank is a populated csrow.
-In the example above 2 dual ranked DIMMs are similarly placed. Thus,
-both csrow0 and csrow1 are populated. On the other hand, when 2 single
-ranked DIMMs are placed in slots DIMM_A0 and DIMM_B0, then they will
-have just one csrow (csrow0) and csrow1 will be empty. The pattern
-repeats itself for csrow2 and csrow3. Also note that some memory
-controllers don't have any logic to identify the memory module, see
-``rankX`` directories below.
-
-The representation of the above is reflected in the directory
-tree in EDAC's sysfs interface. Starting in directory
-``/sys/devices/system/edac/mc``, each memory controller will be
-represented by its own ``mcX`` directory, where ``X`` is the
-index of the MC::
-
- ..../edac/mc/
- |
- |->mc0
- |->mc1
- |->mc2
- ....
-
-Under each ``mcX`` directory each ``csrowX`` is again represented by a
-``csrowX``, where ``X`` is the csrow index::
-
- .../mc/mc0/
- |
- |->csrow0
- |->csrow2
- |->csrow3
- ....
-
-Notice that there is no csrow1, which indicates that csrow0 is composed
-of a single ranked DIMMs. This should also apply in both Channels, in
-order to have dual-channel mode be operational. Since both csrow2 and
-csrow3 are populated, this indicates a dual ranked set of DIMMs for
-channels 0 and 1.
-
-Within each of the ``mcX`` and ``csrowX`` directories are several EDAC
-control and attribute files.
-
-``mcX`` directories
--------------------
-
-In ``mcX`` directories are EDAC control and attribute files for
-this ``X`` instance of the memory controllers.
-
-For a description of the sysfs API, please see:
-
- Documentation/ABI/testing/sysfs-devices-edac
-
-
-``dimmX`` or ``rankX`` directories
-----------------------------------
-
-The recommended way to use the EDAC subsystem is to look at the information
-provided by the ``dimmX`` or ``rankX`` directories [#f5]_.
-
-A typical EDAC system has the following structure under
-``/sys/devices/system/edac/``\ [#f6]_::
-
- /sys/devices/system/edac/

-In the ``dimmX`` directories are EDAC control and attribute files for
-this ``X`` memory module:
-
-- ``size`` - Total memory managed by this csrow attribute file
-
- This attribute file displays, in count of megabytes, the memory
- that this csrow contains.
-
-- ``dimm_ue_count`` - Uncorrectable Errors count attribute file
-
- This attribute file displays the total count of uncorrectable
- errors that have occurred on this DIMM. If panic_on_ue is set
- this counter will not have a chance to increment, since EDAC
- will panic the system.
-
-- ``dimm_ce_count`` - Correctable Errors count attribute file
-
- This attribute file displays the total count of correctable
- errors that have occurred on this DIMM. This count is very
- important to examine. CEs provide early indications that a
- DIMM is beginning to fail. This count field should be
- monitored for non-zero values and report such information
- to the system administrator.
-
-- ``dimm_dev_type`` - Device type attribute file
-
- This attribute file will display what type of DRAM device is
- being utilized on this DIMM.
- Examples:
-
- - x1
- - x2
- - x4
- - x8
-
-- ``dimm_edac_mode`` - EDAC Mode of operation attribute file
-
- This attribute file will display what type of Error detection
- and correction is being utilized.
-
-- ``dimm_label`` - memory module label control file
-
- This control file allows this DIMM to have a label assigned
- to it. With this label in the module, when errors occur
- the output can provide the DIMM label in the system log.
- This becomes vital for panic events to isolate the
- cause of the UE event.
-
- DIMM Labels must be assigned after booting, with information
- that correctly identifies the physical slot with its
- silk screen label. This information is currently very
- motherboard specific and determination of this information
- must occur in userland at this time.
-
-- ``dimm_location`` - location of the memory module
-
- The location can have up to 3 levels, and describe how the
- memory controller identifies the location of a memory module.
- Depending on the type of memory and memory controller, it
- can be:
-
- - *csrow* and *channel* - used when the memory controller
- doesn't identify a single DIMM - e. g. in ``rankX`` dir;
- - *branch*, *channel*, *slot* - typically used on FB-DIMM memory
- controllers;
- - *channel*, *slot* - used on Nehalem and newer Intel drivers.
-
-- ``dimm_mem_type`` - Memory Type attribute file
-
- This attribute file will display what type of memory is currently
- on this csrow. Normally, either buffered or unbuffered memory.
- Examples:
-
- - Registered-DDR
- - Unbuffered-DDR
-
-.. [#f5] On some systems, the memory controller doesn't have any logic
- to identify the memory module. On such systems, the directory is called ``rankX`` and works on a similar way as the ``csrowX`` directories.
- On modern Intel memory controllers, the memory controller identifies the
- memory modules directly. On such systems, the directory is called ``dimmX``.
-
-.. [#f6] There are also some ``power`` directories and ``subsystem``
- symlinks inside the sysfs mapping that are automatically created by
- the sysfs subsystem. Currently, they serve no purpose.
-
-``csrowX`` directories
-----------------------
-
-When CONFIG_EDAC_LEGACY_SYSFS is enabled, sysfs will contain the ``csrowX``
-directories. As this API doesn't work properly for Rambus, FB-DIMMs and
-modern Intel Memory Controllers, this is being deprecated in favor of
-``dimmX`` directories.
-
-In the ``csrowX`` directories are EDAC control and attribute files for
-this ``X`` instance of csrow:
-
-
-- ``ue_count`` - Total Uncorrectable Errors count attribute file
-
- This attribute file displays the total count of uncorrectable
- errors that have occurred on this csrow. If panic_on_ue is set
- this counter will not have a chance to increment, since EDAC
- will panic the system.
-
-
-- ``ce_count`` - Total Correctable Errors count attribute file
-
- This attribute file displays the total count of correctable
- errors that have occurred on this csrow. This count is very
- important to examine. CEs provide early indications that a
- DIMM is beginning to fail. This count field should be
- monitored for non-zero values and report such information
- to the system administrator.
-
-
-- ``size_mb`` - Total memory managed by this csrow attribute file
-
- This attribute file displays, in count of megabytes, the memory
- that this csrow contains.
-
-

-
- This attribute file will display what type of DRAM device is
- being utilized on this DIMM.
- Examples:
-
- - x1
- - x2
- - x4
- - x8
-
-
-- ``ch0_ce_count`` - Channel 0 CE Count attribute file
-
- This attribute file will display the count of CEs on this
- DIMM located in channel 0.
-
-
-- ``ch0_ue_count`` - Channel 0 UE Count attribute file
-
- This attribute file will display the count of UEs on this
- DIMM located in channel 0.
-
-
-- ``ch0_dimm_label`` - Channel 0 DIMM Label control file
-
-
- This control file allows this DIMM to have a label assigned
- to it. With this label in the module, when errors occur
- the output can provide the DIMM label in the system log.
- This becomes vital for panic events to isolate the
- cause of the UE event.
-
- DIMM Labels must be assigned after booting, with information
- that correctly identifies the physical slot with its
- silk screen label. This information is currently very
- motherboard specific and determination of this information
- must occur in userland at this time.
-
-
-- ``ch1_ce_count`` - Channel 1 CE Count attribute file
-
-
- This attribute file will display the count of CEs on this
- DIMM located in channel 1.
-
-
-- ``ch1_ue_count`` - Channel 1 UE Count attribute file
-
-
- This attribute file will display the count of UEs on this
- DIMM located in channel 0.
-
-
-- ``ch1_dimm_label`` - Channel 1 DIMM Label control file
-
- This control file allows this DIMM to have a label assigned
- to it. With this label in the module, when errors occur
- the output can provide the DIMM label in the system log.
- This becomes vital for panic events to isolate the

-
- DIMM Labels must be assigned after booting, with information

-
-
-System Logging
---------------
-
-If logging for UEs and CEs is enabled, then system logs will contain
-information indicating that errors have been detected::
-
- EDAC MC0: CE page 0x283, offset 0xce0, grain 8, syndrome 0x6ec3, row 0, channel 1 "DIMM_B1": amd76x_edac
- EDAC MC0: CE page 0x1e5, offset 0xfb0, grain 8, syndrome 0xb741, row 0, channel 1 "DIMM_B1": amd76x_edac
-
-
-The structure of the message is:
-
- +---------------------------------------+-------------+
- | Content | Example |
- +=======================================+=============+
- | The memory controller | MC0 |
- +---------------------------------------+-------------+
- | Error type | CE |
- +---------------------------------------+-------------+
- | Memory page | 0x283 |
- +---------------------------------------+-------------+
- | Offset in the page | 0xce0 |
- +---------------------------------------+-------------+
- | The byte granularity | grain 8 |
- | or resolution of the error | |
- +---------------------------------------+-------------+
- | The error syndrome | 0xb741 |
- +---------------------------------------+-------------+
- | Memory row | row 0 |
- +---------------------------------------+-------------+
- | Memory channel | channel 1 |
- +---------------------------------------+-------------+
- | DIMM label, if set prior | DIMM B1 |
- +---------------------------------------+-------------+
- | And then an optional, driver-specific | |
- | message that may have additional | |
- | information. | |
- +---------------------------------------+-------------+
-
-Both UEs and CEs with no info will lack all but memory controller, error
-type, a notice of "no info" and then an optional, driver-specific error
-message.
-
-
-PCI Bus Parity Detection
-------------------------
-
-On Header Type 00 devices, the primary status is looked at for any
-parity error regardless of whether parity is enabled on the device or
-not. (The spec indicates parity is generated in some cases). On Header
-Type 01 bridges, the secondary status register is also looked at to see
-if parity occurred on the bus on the other side of the bridge.
-
-
-Sysfs configuration
--------------------
-
-Under ``/sys/devices/system/edac/pci`` are control and attribute files as
-follows:
-
-
-- ``check_pci_parity`` - Enable/Disable PCI Parity checking control file
-
- This control file enables or disables the PCI Bus Parity scanning
- operation. Writing a 1 to this file enables the scanning. Writing
- a 0 to this file disables the scanning.
-
- Enable::
-
- echo "1" >/sys/devices/system/edac/pci/check_pci_parity
-
- Disable::
-
- echo "0" >/sys/devices/system/edac/pci/check_pci_parity
-
-
-- ``pci_parity_count`` - Parity Count
-
- This attribute file will display the number of parity errors that
- have been detected.
-
-
-Module parameters
------------------
-
-- ``edac_mc_panic_on_ue`` - Panic on UE control file
-
- An uncorrectable error will cause a machine panic. This is usually
- desirable. It is a bad idea to continue when an uncorrectable error
- occurs - it is indeterminate what was uncorrected and the operating
- system context might be so mangled that continuing will lead to further
- corruption. If the kernel has MCE configured, then EDAC will never
- notice the UE.
-
- LOAD TIME::
-
- module/kernel parameter: edac_mc_panic_on_ue=[0|1]
-
- RUN TIME::
-
- echo "1" > /sys/module/edac_core/parameters/edac_mc_panic_on_ue
-
-
-- ``edac_mc_log_ue`` - Log UE control file
-
-
- Generate kernel messages describing uncorrectable errors. These errors
- are reported through the system message log system. UE statistics
- will be accumulated even when UE logging is disabled.
-
- LOAD TIME::
-
- module/kernel parameter: edac_mc_log_ue=[0|1]
-
- RUN TIME::
-
- echo "1" > /sys/module/edac_core/parameters/edac_mc_log_ue
-
-
-- ``edac_mc_log_ce`` - Log CE control file
-
-
- Generate kernel messages describing correctable errors. These
- errors are reported through the system message log system.
- CE statistics will be accumulated even when CE logging is disabled.
-
- LOAD TIME::
-
- module/kernel parameter: edac_mc_log_ce=[0|1]
-
- RUN TIME::
-
- echo "1" > /sys/module/edac_core/parameters/edac_mc_log_ce
-
-
-- ``edac_mc_poll_msec`` - Polling period control file
-
-
- The time period, in milliseconds, for polling for error information.
- Too small a value wastes resources. Too large a value might delay
- necessary handling of errors and might loose valuable information for
- locating the error. 1000 milliseconds (once each second) is the current
- default. Systems which require all the bandwidth they can get, may
- increase this.
-
- LOAD TIME::
-
- module/kernel parameter: edac_mc_poll_msec=[0|1]
-
- RUN TIME::
-
- echo "1000" > /sys/module/edac_core/parameters/edac_mc_poll_msec
-
-
-- ``panic_on_pci_parity`` - Panic on PCI PARITY Error
-
-
- This control file enables or disables panicking when a parity
- error has been detected.
-
-
- module/kernel parameter::
-
- edac_panic_on_pci_pe=[0|1]
-
- Enable::
-
- echo "1" > /sys/module/edac_core/parameters/edac_panic_on_pci_pe
-
- Disable::
-
- echo "0" > /sys/module/edac_core/parameters/edac_panic_on_pci_pe
-
-
-
-EDAC device type
-----------------
-
-In the header file, edac_pci.h, there is a series of edac_device structures
-and APIs for the EDAC_DEVICE.
-
-User space access to an edac_device is through the sysfs interface.
-
-At the location ``/sys/devices/system/edac`` (sysfs) new edac_device devices
-will appear.
-
-There is a three level tree beneath the above ``edac`` directory. For example,
-the ``test_device_edac`` device (found at the http://bluesmoke.sourceforget.net
-website) installs itself as::
-
- /sys/devices/system/edac/test-instance
-
-in this directory are various controls, a symlink and one or more ``instance``
-directories.
-
-The standard default controls are:
-
- ============== =======================================================
- log_ce boolean to log CE events
- log_ue boolean to log UE events
- panic_on_ue boolean to ``panic`` the system if an UE is encountered
- (default off, can be set true via startup script)
- poll_msec time period between POLL cycles for events
- ============== =======================================================
-
-The test_device_edac device adds at least one of its own custom control:
-
- ============== ==================================================
- test_bits which in the current test driver does nothing but
- show how it is installed. A ported driver can
- add one or more such controls and/or attributes
- for specific uses.
- One out-of-tree driver uses controls here to allow
- for ERROR INJECTION operations to hardware
- injection registers
- ============== ==================================================
-
-The symlink points to the 'struct dev' that is registered for this edac_device.
-
-Instances
----------
-
-One or more instance directories are present. For the ``test_device_edac``
-case:
-
- +----------------+
- | test-instance0 |
- +----------------+
-
-
-In this directory there are two default counter attributes, which are totals of
-counter in deeper subdirectories.
-
- ============== ====================================
- ce_count total of CE events of subdirectories
- ue_count total of UE events of subdirectories
- ============== ====================================
-
-Blocks
-------
-
-At the lowest directory level is the ``block`` directory. There can be 0, 1
-or more blocks specified in each instance:
-
- +-------------+
- | test-block0 |
- +-------------+
-
-In this directory the default attributes are:
-
- ============== ================================================
- ce_count which is counter of CE events for this ``block``
- of hardware being monitored
- ue_count which is counter of UE events for this ``block``
- of hardware being monitored
- ============== ================================================
-
-
-The ``test_device_edac`` device adds 4 attributes and 1 control:
-
- ================== ====================================================
- test-block-bits-0 for every POLL cycle this counter
- is incremented
- test-block-bits-1 every 10 cycles, this counter is bumped once,
- and test-block-bits-0 is set to 0
- test-block-bits-2 every 100 cycles, this counter is bumped once,
- and test-block-bits-1 is set to 0
- test-block-bits-3 every 1000 cycles, this counter is bumped once,
- and test-block-bits-2 is set to 0
- ================== ====================================================
-
-
- ================== ====================================================
- reset-counters writing ANY thing to this control will
- reset all the above counters.
- ================== ====================================================
-
-
-Use of the ``test_device_edac`` driver should enable any others to create their own
-unique drivers for their hardware systems.
-
-The ``test_device_edac`` sample driver is located at the
-http://bluesmoke.sourceforge.net project site for EDAC.
-
-
-Usage of EDAC APIs on Nehalem and newer Intel CPUs
---------------------------------------------------
-
-On older Intel architectures, the memory controller was part of the North
-Bridge chipset. Nehalem, Sandy Bridge, Ivy Bridge, Haswell, Sky Lake and
-newer Intel architectures integrated an enhanced version of the memory
-controller (MC) inside the CPUs.
-
-This chapter will cover the differences of the enhanced memory controllers
-found on newer Intel CPUs, such as ``i7core_edac``, ``sb_edac`` and
-``sbx_edac`` drivers.
-
-.. note::
-
- The Xeon E7 processor families use a separate chip for the memory
- controller, called Intel Scalable Memory Buffer. This section doesn't
- apply for such families.
-
-1) There is one Memory Controller per Quick Patch Interconnect
- (QPI). At the driver, the term "socket" means one QPI. This is
- associated with a physical CPU socket.
-
- Each MC have 3 physical read channels, 3 physical write channels and
- 3 logic channels. The driver currently sees it as just 3 channels.
- Each channel can have up to 3 DIMMs.
-
- The minimum known unity is DIMMs. There are no information about csrows.
- As EDAC API maps the minimum unity is csrows, the driver sequentially
- maps channel/DIMM into different csrows.
-
- For example, supposing the following layout::
-
- Ch0 phy rd0, wr0 (0x063f4031): 2 ranks, UDIMMs
- dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
- dimm 1 1024 Mb offset: 4, bank: 8, rank: 1, row: 0x4000, col: 0x400
- Ch1 phy rd1, wr1 (0x063f4031): 2 ranks, UDIMMs
- dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
- Ch2 phy rd3, wr3 (0x063f4031): 2 ranks, UDIMMs
- dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
-
- The driver will map it as::
-
- csrow0: channel 0, dimm0
- csrow1: channel 0, dimm1
- csrow2: channel 1, dimm0
- csrow3: channel 2, dimm0
-
- exports one DIMM per csrow.
-
- Each QPI is exported as a different memory controller.
-
-2) The MC has the ability to inject errors to test drivers. The drivers
- implement this functionality via some error injection nodes:
-
- For injecting a memory error, there are some sysfs nodes, under
- ``/sys/devices/system/edac/mc/mc?/``:
-
- - ``inject_addrmatch/*``:
- Controls the error injection mask register. It is possible to specify
- several characteristics of the address to match an error code::
-
- dimm = the affected dimm. Numbers are relative to a channel;
- rank = the memory rank;
- channel = the channel that will generate an error;
- bank = the affected bank;
- page = the page address;
- column (or col) = the address column.
-
- each of the above values can be set to "any" to match any valid value.
-
- At driver init, all values are set to any.
-
- For example, to generate an error at rank 1 of dimm 2, for any channel,
- any bank, any page, any column::
-
- echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
- echo 1 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
-
- To return to the default behaviour of matching any, you can do::
-
- echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
- echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
-
- - ``inject_eccmask``:
- specifies what bits will have troubles,
-
- - ``inject_section``:
- specifies what ECC cache section will get the error::
-
- 3 for both
- 2 for the highest
- 1 for the lowest
-
- - ``inject_type``:
- specifies the type of error, being a combination of the following bits::
-
- bit 0 - repeat
- bit 1 - ecc
- bit 2 - parity
-
- - ``inject_enable``:
- starts the error generation when something different than 0 is written.
-
- All inject vars can be read. root permission is needed for write.
-
- Datasheet states that the error will only be generated after a write on an
- address that matches inject_addrmatch. It seems, however, that reading will
- also produce an error.
-
- For example, the following code will generate an error for any write access
- at socket 0, on any DIMM/address on channel 2::
-
- echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/channel
- echo 2 >/sys/devices/system/edac/mc/mc0/inject_type
- echo 64 >/sys/devices/system/edac/mc/mc0/inject_eccmask
- echo 3 >/sys/devices/system/edac/mc/mc0/inject_section
- echo 1 >/sys/devices/system/edac/mc/mc0/inject_enable
- dd if=/dev/mem of=/dev/null seek=16k bs=4k count=1 >& /dev/null
-
- For socket 1, it is needed to replace "mc0" by "mc1" at the above
- commands.
-
- The generated error message will look like::
-
- EDAC MC0: UE row 0, channel-a= 0 channel-b= 0 labels "-": NON_FATAL (addr = 0x0075b980, socket=0, Dimm=0, Channel=2, syndrome=0x00000040, count=1, Err=8c0000400001009f:4000080482 (read error: read ECC error))
-
-3) Corrected Error memory register counters
-
- Those newer MCs have some registers to count memory errors. The driver
- uses those registers to report Corrected Errors on devices with Registered
- DIMMs.
-
- However, those counters don't work with Unregistered DIMM. As the chipset
- offers some counters that also work with UDIMMs (but with a worse level of
- granularity than the default ones), the driver exposes those registers for
- UDIMM memories.
-
- They can be read by looking at the contents of ``all_channel_counts/``::
-
- $ for i in /sys/devices/system/edac/mc/mc0/all_channel_counts/*; do echo $i; cat $i; done
- /sys/devices/system/edac/mc/mc0/all_channel_counts/udimm0
- 0
- /sys/devices/system/edac/mc/mc0/all_channel_counts/udimm1
- 0
- /sys/devices/system/edac/mc/mc0/all_channel_counts/udimm2
- 0
-
- What happens here is that errors on different csrows, but at the same
- dimm number will increment the same counter.
- So, in this memory mapping::
-
- csrow0: channel 0, dimm0
- csrow1: channel 0, dimm1
- csrow2: channel 1, dimm0
- csrow3: channel 2, dimm0
-
- The hardware will increment udimm0 for an error at the first dimm at either
- csrow0, csrow2 or csrow3;
-
- The hardware will increment udimm1 for an error at the second dimm at either
- csrow0, csrow2 or csrow3;
-
- The hardware will increment udimm2 for an error at the third dimm at either
- csrow0, csrow2 or csrow3;
-
-4) Standard error counters
-
- The standard error counters are generated when an mcelog error is received
- by the driver. Since, with UDIMM, this is counted by software, it is
- possible that some errors could be lost. With RDIMM's, they display the
- contents of the registers

-Security bugs
-=============
-
-Linux kernel developers take security very seriously. As such, we'd
-like to know when a security bug is found so that it can be fixed and
-disclosed as quickly as possible. Please report security bugs to the
-Linux kernel security team.
-
-Contact
--------
-
-The Linux kernel security team can be contacted by email at
-<security@kernel.org>. This is a private list of security officers
-who will help verify the bug report and develop and release a fix.
-If you already have a fix, please include it with your report, as
-that can speed up the process considerably. It is possible that the
-security team will bring in extra help from area maintainers to
-understand and fix the security vulnerability.
-
-As it is with any bug, the more information provided the easier it
-will be to diagnose and fix. Please review the procedure outlined in
-'Documentation/admin-guide/reporting-issues.rst' if you are unclear about what
-information is helpful. Any exploit code is very helpful and will not
-be released without consent from the reporter unless it has already been
-made public.
-
-Please send plain text emails without attachments where possible.
-It is much harder to have a context-quoted discussion about a complex
-issue if all the details are hidden away in attachments. Think of it like a
-:doc:`regular patch submission <../process/submitting-patches>`
-(even if you don't have a patch yet): describe the problem and impact, list
-reproduction steps, and follow it with a proposed fix, all in plain text.
-
-Disclosure and embargoed information
-------------------------------------
-
-The security list is not a disclosure channel. For that, see Coordination
-below.
-
-Once a robust fix has been developed, the release process starts. Fixes
-for publicly known bugs are released immediately.
-
-Although our preference is to release fixes for publicly undisclosed bugs
-as soon as they become available, this may be postponed at the request of
-the reporter or an affected party for up to 7 calendar days from the start
-of the release process, with an exceptional extension to 14 calendar days
-if it is agreed that the criticality of the bug requires more time. The
-only valid reason for deferring the publication of a fix is to accommodate
-the logistics of QA and large scale rollouts which require release
-coordination.
-
-While embargoed information may be shared with trusted individuals in
-order to develop a fix, such information will not be published alongside
-the fix or on any other disclosure channel without the permission of the
-reporter. This includes but is not limited to the original bug report
-and followup discussions (if any), exploits, CVE information or the
-identity of the reporter.
-
-In other words our only interest is in getting bugs fixed. All other
-information submitted to the security list and any followup discussions
-of the report are treated confidentially even after the embargo has been
-lifted, in perpetuity.
-
-Coordination
-------------
-
-Fixes for sensitive bugs, such as those that might lead to privilege
-escalations, may need to be coordinated with the private
-<linux-distros@vs.openwall.org> mailing list so that distribution vendors
-are well prepared to issue a fixed kernel upon public disclosure of the
-upstream fix. Distros will need some time to test the proposed patch and
-will generally request at least a few days of embargo, and vendor update
-publication prefers to happen Tuesday through Thursday. When appropriate,
-the security team can assist with this coordination, or the reporter can
-include linux-distros from the start. In this case, remember to prefix
-the email Subject line with "[vs]" as described in the linux-distros wiki:
-<http://oss-security.openwall.org/wiki/mailing-lists/distros#how-to-use-the-lists>
-
-CVE assignment
---------------
-
-The security team does not normally assign CVEs, nor do we require them
-for reports or fixes, as this can needlessly complicate the process and
-may delay the bug handling. If a reporter wishes to have a CVE identifier
-assigned ahead of public disclosure, they will need to contact the private
-linux-distros list, described above. When such a CVE identifier is known
-before a patch is provided, it is desirable to mention it in the commit
-message if the reporter agrees.
-
-Non-disclosure agreements
--------------------------
-
-The Linux kernel security team is not a formal body and therefore unable
-to enter any non-disclosure agreements.

+even if the server did not specify a timeout and default_request_timeout is
+set to 0. If max_request_timeout is greater than 0 and the server set a timeout
+greater than max_request_timeout or default_request_timeout is set to a value
+greater than max_request_timeout, the system will use max_request_timeout as the

+For timeouts, if the server does not respond to the request by the time

+===================
+Correctable memory errors are very common on servers. Soft-offline is kernel's
+solution for memory pages having (excessive) corrected memory errors.
+
+For different types of page, soft-offline has different behaviors / costs.
+
+- For a raw error page, soft-offline migrates the in-use page's content to
+ a new raw page.
+
+- For a page that is part of a transparent hugepage, soft-offline splits the
+ transparent hugepage into raw pages, then migrates only the raw error page.
+ As a result, user is transparently backed by 1 less hugepage, impacting
+ memory access performance.
+
+- For a page that is part of a HugeTLB hugepage, soft-offline first migrates
+ the entire HugeTLB hugepage, during which a free hugepage will be consumed
+ as migration target. Then the original hugepage is dissolved into raw
+ pages without compensation, reducing the capacity of the HugeTLB pool by 1.
+
+It is user's call to choose between reliability (staying away from fragile
+physical memory) vs performance / capacity implications in transparent and
+HugeTLB cases.

+Intel thermal throttle events reporting
+=======================================

+
+Introduction
+------------
+
+Intel processors have built in automatic and adaptive thermal monitoring
+mechanisms that force the processor to reduce its power consumption in order
+to operate within predetermined temperature limits.
+
+Refer to section "THERMAL MONITORING AND PROTECTION" in the "Intel® 64 and
+IA-32 Architectures Software Developer’s Manual Volume 3 (3A, 3B, 3C, & 3D):
+System Programming Guide" for more details.
+
+In general, there are two mechanisms to control the core temperature of the
+processor. They are called "Thermal Monitor 1 (TM1) and Thermal Monitor 2 (TM2)".
+
+The status of the temperature sensor that triggers the thermal monitor (TM1/TM2)
+is indicated through the "thermal status flag" and "thermal status log flag" in
+MSR_IA32_THERM_STATUS for core level and MSR_IA32_PACKAGE_THERM_STATUS for
+package level.
+
+Thermal Status flag, bit 0 — When set, indicates that the processor core
+temperature is currently at the trip temperature of the thermal monitor and that
+the processor power consumption is being reduced via either TM1 or TM2, depending
+on which is enabled. When clear, the flag indicates that the core temperature is
+below the thermal monitor trip temperature. This flag is read only.
+
+Thermal Status Log flag, bit 1 — When set, indicates that the thermal sensor has
+tripped since the last power-up or reset or since the last time that software
+cleared this flag. This flag is a sticky bit; once set it remains set until
+cleared by software or until a power-up or reset of the processor. The default
+state is clear.
+
+It is possible that when user reads MSR_IA32_THERM_STATUS or
+MSR_IA32_PACKAGE_THERM_STATUS, TM1/TM2 is not active. In this case,
+"Thermal Status flag" will read "0" and the "Thermal Status Log flag" will be set
+to show any previous "TM1/TM2" activation. But since it needs to be cleared by
+the software, it can't show the number of occurrences of "TM1/TM2" activations.
+
+Hence, Linux provides counters of how many times the "Thermal Status flag" was
+set. Also presents how long the "Thermal Status flag" was active in milliseconds.
+Using these counters, users can check if the performance was limited because of
+thermal events. It is recommended to read from sysfs instead of directly reading
+MSRs as the "Thermal Status Log flag" is reset by the driver to implement rate
+control.
+
+Sysfs Interface
+---------------
+
+Thermal throttling events are presented for each CPU under
+"/sys/devices/system/cpu/cpuX/thermal_throttle/", where "X" is the CPU number.
+
+All these counters are read-only. They can't be reset to 0. So, they can potentially
+overflow after reaching the maximum 64 bit unsigned integer.
+
+``core_throttle_count``
+ Shows the number of times "Thermal Status flag" changed from 0 to 1 for this
+ CPU since OS boot and thermal vector is initialized. This is a 64 bit counter.
+
+``package_throttle_count``
+ Shows the number of times "Thermal Status flag" changed from 0 to 1 for the
+ package containing this CPU since OS boot and thermal vector is initialized.
+ Package status is broadcast to all CPUs; all CPUs in the package increment
+ this count. This is a 64-bit counter.
+
+``core_throttle_max_time_ms``
+ Shows the maximum amount of time for which "Thermal Status flag" has been
+ set to 1 for this CPU at the core level since OS boot and thermal vector
+ is initialized.
+
+``package_throttle_max_time_ms``
+ Shows the maximum amount of time for which "Thermal Status flag" has been
+ set to 1 for the package containing this CPU since OS boot and thermal
+ vector is initialized.
+
+``core_throttle_total_time_ms``
+ Shows the cumulative time for which "Thermal Status flag" has been
+ set to 1 for this CPU for core level since OS boot and thermal vector
+ is initialized.
+
+``package_throttle_total_time_ms``
+ Shows the cumulative time for which "Thermal Status flag" has been set
+ to 1 for the package containing this CPU since OS boot and thermal vector

+How to verify bugs and bisect regressions
+=========================================
+
+This document describes how to check if some Linux kernel problem occurs in code
+currently supported by developers -- to then explain how to locate the change
+causing the issue, if it is a regression (e.g. did not happen with earlier
+versions).
+
+The text aims at people running kernels from mainstream Linux distributions on
+commodity hardware who want to report a kernel bug to the upstream Linux
+developers. Despite this intent, the instructions work just as well for users
+who are already familiar with building their own kernels: they help avoid
+mistakes occasionally made even by experienced developers.
+
+..
+ Note: if you see this note, you are reading the text's source file. You
+ might want to switch to a rendered version: it makes it a lot easier to
+ read and navigate this document -- especially when you want to look something
+ up in the reference section, then jump back to where you left off.
+..

+
+The essence of the process (aka 'TL;DR')
+========================================
+
+*[If you are new to building or bisecting Linux, ignore this section and head
+over to the* ':ref:`step-by-step guide <introguide_bissbs>`' *below. It utilizes
+the same commands as this section while describing them in brief fashion. The
+steps are nevertheless easy to follow and together with accompanying entries
+in a reference section mention many alternatives, pitfalls, and additional
+aspects, all of which might be essential in your present case.]*
+
+**In case you want to check if a bug is present in code currently supported by
+developers**, execute just the *preparations* and *segment 1*; while doing so,
+consider the newest Linux kernel you regularly use to be the 'working' kernel.
+In the following example that's assumed to be 6.0, which is why its sources
+will be used to prepare the .config file.
+
+**In case you face a regression**, follow the steps at least till the end of
+*segment 2*. Then you can submit a preliminary report -- or continue with
+*segment 3*, which describes how to perform a bisection needed for a
+full-fledged regression report. In the following example 6.0.13 is assumed to be
+the 'working' kernel and 6.1.5 to be the first 'broken', which is why 6.0
+will be considered the 'good' release and used to prepare the .config file.
+
+* **Preparations**: set up everything to build your own kernels::
+
+ # * Remove any software that depends on externally maintained kernel modules
+ # or builds any automatically during bootup.
+ # * Ensure Secure Boot permits booting self-compiled Linux kernels.
+ # * If you are not already running the 'working' kernel, reboot into it.
+ # * Install compilers and everything else needed for building Linux.
+ # * Ensure to have 15 Gigabyte free space in your home directory.

+ make olddefconfig
+ # * Ensure the former command picked the .config of the 'working' kernel.

+ # * Hint: at this point you might want to adjust the build configuration;
+ # you'll have to, if you are running Debian.
+ make olddefconfig
+ cp .config ~/kernel-config-working
+
+* **Segment 1**: build a kernel from the latest mainline codebase.
+
+ This among others checks if the problem was fixed already and which developers
+ later need to be told about the problem; in case of a regression, this rules
+ out a .config change as root of the problem.
+
+ a) Checking out latest mainline code::
+
+ cd ~/linux/
+ git switch --discard-changes --detach mainline/master
+
+ b) Build, install, and boot a kernel::
+
+ cp ~/kernel-config-working .config
+ make olddefconfig
+ make -j $(nproc --all)
+ # * Make sure there is enough disk space to hold another kernel:
+ df -h /boot/ /lib/modules/
+ # * Note: on Arch Linux, its derivatives and a few other distributions
+ # the following commands will do nothing at all or only part of the
+ # job. See the step-by-step guide for further details.
+ sudo make modules_install
+ command -v installkernel && sudo make install
+ # * Check how much space your self-built kernel actually needs, which
+ # enables you to make better estimates later:
+ du -ch /boot/*$(make -s kernelrelease)* | tail -n 1
+ du -sh /lib/modules/$(make -s kernelrelease)/
+ # * Hint: the output of the following command will help you pick the
+ # right kernel from the boot menu:
+ make -s kernelrelease | tee -a ~/kernels-built
+ reboot
+ # * Once booted, ensure you are running the kernel you just built by
+ # checking if the output of the next two commands matches:
+ tail -n 1 ~/kernels-built
+ uname -r
+ cat /proc/sys/kernel/tainted
+
+ c) Check if the problem occurs with this kernel as well.
+
+* **Segment 2**: ensure the 'good' kernel is also a 'working' kernel.
+
+ This among others verifies the trimmed .config file actually works well, as
+ bisecting with it otherwise would be a waste of time:
+
+ a) Start by checking out the sources of the 'good' version::
+
+ cd ~/linux/
+ git switch --discard-changes --detach v6.0
+
+ b) Build, install, and boot a kernel as described earlier in *segment 1,
+ section b* -- just feel free to skip the 'du' commands, as you have a rough
+ estimate already.
+
+ c) Ensure the feature that regressed with the 'broken' kernel actually works
+ with this one.
+
+* **Segment 3**: perform and validate the bisection.
+
+ a) Retrieve the sources for your 'bad' version::
+
+ git remote set-branches --add stable linux-6.1.y
+ git fetch stable
+
+ b) Initialize the bisection::
+
+ cd ~/linux/
+ git bisect start
+ git bisect good v6.0
+ git bisect bad v6.1.5
+
+ c) Build, install, and boot a kernel as described earlier in *segment 1,
+ section b*.
+
+ In case building or booting the kernel fails for unrelated reasons, run
+ ``git bisect skip``. In all other outcomes, check if the regressed feature
+ works with the newly built kernel. If it does, tell Git by executing
+ ``git bisect good``; if it does not, run ``git bisect bad`` instead.
+
+ All three commands will make Git check out another commit; then re-execute
+ this step (e.g. build, install, boot, and test a kernel to then tell Git
+ the outcome). Do so again and again until Git shows which commit broke
+ things. If you run short of disk space during this process, check the
+ section 'Complementary tasks: cleanup during and after the process'
+ below.
+
+ d) Once your finished the bisection, put a few things away::
+
+ cd ~/linux/
+ git bisect log > ~/bisect-log
+ cp .config ~/bisection-config-culprit
+ git bisect reset
+
+ e) Try to verify the bisection result::
+
+ git switch --discard-changes --detach mainline/master
+ git revert --no-edit cafec0cacaca0
+ cp ~/kernel-config-working .config
+ ./scripts/config --set-str CONFIG_LOCALVERSION '-local-cafec0cacaca0-reverted'
+
+ This is optional, as some commits are impossible to revert. But if the
+ second command worked flawlessly, build, install, and boot one more kernel
+ kernel; just this time skip the first command copying the base .config file
+ over, as that already has been taken care off.
+
+* **Complementary tasks**: cleanup during and after the process.
+
+ a) To avoid running out of disk space during a bisection, you might need to
+ remove some kernels you built earlier. You most likely want to keep those
+ you built during segment 1 and 2 around for a while, but you will most
+ likely no longer need kernels tested during the actual bisection
+ (Segment 3 c). You can list them in build order using::
+
+ ls -ltr /lib/modules/*-local*
+
+ To then for example erase a kernel that identifies itself as
+ '6.0-rc1-local-gcafec0cacaca0', use this::
+
+ sudo rm -rf /lib/modules/6.0-rc1-local-gcafec0cacaca0
+ sudo kernel-install -v remove 6.0-rc1-local-gcafec0cacaca0
+ # * Note, on some distributions kernel-install is missing
+ # or does only part of the job.
+
+ b) If you performed a bisection and successfully validated the result, feel
+ free to remove all kernels built during the actual bisection (Segment 3 c);
+ the kernels you built earlier and later you might want to keep around for
+ a week or two.
+
+* **Optional task**: test a debug patch or a proposed fix later::
+
+ git fetch mainline
+ git switch --discard-changes --detach mainline/master
+ git apply /tmp/foobars-proposed-fix-v1.patch
+ cp ~/kernel-config-working .config
+ ./scripts/config --set-str CONFIG_LOCALVERSION '-local-foobars-fix-v1'
+
+ Build, install, and boot a kernel as described in *segment 1, section b* --
+ but this time omit the first command copying the build configuration over,
+ as that has been taken care of already.

+
+Step-by-step guide on how to verify bugs and bisect regressions
+===============================================================
+
+This guide describes how to set up your own Linux kernels for investigating bugs
+or regressions you intend to report. How far you want to follow the instructions
+depends on your issue:
+
+Execute all steps till the end of *segment 1* to **verify if your kernel problem
+is present in code supported by Linux kernel developers**. If it is, you are all
+set to report the bug -- unless it did not happen with earlier kernel versions,
+as then your want to at least continue with *segment 2* to **check if the issue
+qualifies as regression** which receive priority treatment. Depending on the
+outcome you then are ready to report a bug or submit a preliminary regression
+report; instead of the latter your could also head straight on and follow
+*segment 3* to **perform a bisection** for a full-fledged regression report
+developers are obliged to act upon.
+
+ :ref:`Preparations: set up everything to build your own kernels <introprep_bissbs>`.
+
+ :ref:`Segment 1: try to reproduce the problem with the latest codebase <introlatestcheck_bissbs>`.
+
+ :ref:`Segment 2: check if the kernels you build work fine <introworkingcheck_bissbs>`.
+
+ :ref:`Segment 3: perform a bisection and validate the result <introbisect_bissbs>`.
+
+ :ref:`Complementary tasks: cleanup during and after following this guide <introclosure_bissbs>`.
+
+ :ref:`Optional tasks: test reverts, patches, or later versions <introoptional_bissbs>`.
+
+The steps in each segment illustrate the important aspects of the process, while
+a comprehensive reference section holds additional details for almost all of the
+steps. The reference section sometimes also outlines alternative approaches,
+pitfalls, as well as problems that might occur at the particular step -- and how
+to get things rolling again.
+
+For further details on how to report Linux kernel issues or regressions check
+out Documentation/admin-guide/reporting-issues.rst, which works in conjunction
+with this document. It among others explains why you need to verify bugs with
+the latest 'mainline' kernel (e.g. versions like 6.0, 6.1-rc1, or 6.1-rc6),
+even if you face a problem with a kernel from a 'stable/longterm' series
+(say 6.0.13).
+
+For users facing a regression that document also explains why sending a
+preliminary report after segment 2 might be wise, as the regression and its
+culprit might be known already. For further details on what actually qualifies
+as a regression check out Documentation/admin-guide/reporting-regressions.rst.
+
+If you run into any problems while following this guide or have ideas how to
+improve it, :ref:`please let the kernel developers know <submit_improvements_vbbr>`.
+
+.. _introprep_bissbs:
+
+Preparations: set up everything to build your own kernels
+---------------------------------------------------------
+
+The following steps lay the groundwork for all further tasks.
+
+Note: the instructions assume you are building and testing on the same
+machine; if you want to compile the kernel on another system, check
+:ref:`Build kernels on a different machine <buildhost_bis>` below.
+
+.. _backup_bissbs:
+
+* Create a fresh backup and put system repair and restore tools at hand, just
+ to be prepared for the unlikely case of something going sideways.
+
+ [:ref:`details <backup_bisref>`]
+
+.. _vanilla_bissbs:
+
+* Remove all software that depends on externally developed kernel drivers or
+ builds them automatically. That includes but is not limited to DKMS, openZFS,
+ VirtualBox, and Nvidia's graphics drivers (including the GPLed kernel module).
+
+ [:ref:`details <vanilla_bisref>`]
+
+.. _secureboot_bissbs:
+
+* On platforms with 'Secure Boot' or similar solutions, prepare everything to
+ ensure the system will permit your self-compiled kernel to boot. The
+ quickest and easiest way to achieve this on commodity x86 systems is to
+ disable such techniques in the BIOS setup utility; alternatively, remove
+ their restrictions through a process initiated by
+ ``mokutil --disable-validation``.
+
+ [:ref:`details <secureboot_bisref>`]
+
+.. _rangecheck_bissbs:
+
+* Determine the kernel versions considered 'good' and 'bad' throughout this
+ guide:
+
+ * Do you follow this guide to verify if a bug is present in the code the
+ primary developers care for? Then consider the version of the newest kernel
+ you regularly use currently as 'good' (e.g. 6.0, 6.0.13, or 6.1-rc2).
+
+ * Do you face a regression, e.g. something broke or works worse after
+ switching to a newer kernel version? In that case it depends on the version
+ range during which the problem appeared:
+
+ * Something regressed when updating from a stable/longterm release
+ (say 6.0.13) to a newer mainline series (like 6.1-rc7 or 6.1) or a
+ stable/longterm version based on one (say 6.1.5)? Then consider the
+ mainline release your working kernel is based on to be the 'good'
+ version (e.g. 6.0) and the first version to be broken as the 'bad' one
+ (e.g. 6.1-rc7, 6.1, or 6.1.5). Note, at this point it is merely assumed
+ that 6.0 is fine; this hypothesis will be checked in segment 2.
+
+ * Something regressed when switching from one mainline version (say 6.0) to
+ a later one (like 6.1-rc1) or a stable/longterm release based on it
+ (say 6.1.5)? Then regard the last working version (e.g. 6.0) as 'good' and
+ the first broken (e.g. 6.1-rc1 or 6.1.5) as 'bad'.
+
+ * Something regressed when updating within a stable/longterm series (say
+ from 6.0.13 to 6.0.15)? Then consider those versions as 'good' and 'bad'
+ (e.g. 6.0.13 and 6.0.15), as you need to bisect within that series.
+
+ *Note, do not confuse 'good' version with 'working' kernel; the latter term
+ throughout this guide will refer to the last kernel that has been working
+ fine.*
+
+ [:ref:`details <rangecheck_bisref>`]
+
+.. _bootworking_bissbs:
+
+* Boot into the 'working' kernel and briefly use the apparently broken feature.
+
+ [:ref:`details <bootworking_bisref>`]
+
+.. _diskspace_bissbs:
+
+* Ensure to have enough free space for building Linux. 15 Gigabyte in your home
+ directory should typically suffice. If you have less available, be sure to pay
+ attention to later steps about retrieving the Linux sources and handling of
+ debug symbols: both explain approaches reducing the amount of space, which
+ should allow you to master these tasks with about 4 Gigabytes free space.
+
+ [:ref:`details <diskspace_bisref>`]
+
+.. _buildrequires_bissbs:
+
+* Install all software required to build a Linux kernel. Often you will need:
+ 'bc', 'binutils' ('ld' et al.), 'bison', 'flex', 'gcc', 'git', 'openssl',
+ 'pahole', 'perl', and the development headers for 'libelf' and 'openssl'. The
+ reference section shows how to quickly install those on various popular Linux
+ distributions.
+
+ [:ref:`details <buildrequires_bisref>`]
+
+.. _sources_bissbs:
+
+* Retrieve the mainline Linux sources; then change into the directory holding
+ them, as all further commands in this guide are meant to be executed from
+ there.
+
+ *Note, the following describe how to retrieve the sources using a full
+ mainline clone, which downloads about 2,75 GByte as of early 2024. The*
+ :ref:`reference section describes two alternatives <sources_bisref>` *:
+ one downloads less than 500 MByte, the other works better with unreliable
+ internet connections.*
+
+ Execute the following command to retrieve a fresh mainline codebase while
+ preparing things to add branches for stable/longterm series later::
+
+ git clone -o mainline --no-checkout \
+ https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git ~/linux/
+ cd ~/linux/
+ git remote add -t master stable \
+ https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
+
+ [:ref:`details <sources_bisref>`]
+
+.. _stablesources_bissbs:
+
+* Is one of the versions you earlier established as 'good' or 'bad' a stable or
+ longterm release (say 6.1.5)? Then download the code for the series it belongs
+ to ('linux-6.1.y' in this example)::
+
+ git remote set-branches --add stable linux-6.1.y
+ git fetch stable
+
+.. _oldconfig_bissbs:
+
+* Start preparing a kernel build configuration (the '.config' file).
+
+ Before doing so, ensure you are still running the 'working' kernel an earlier
+ step told you to boot; if you are unsure, check the current kernelrelease
+ identifier using ``uname -r``.
+
+ Afterwards check out the source code for the version earlier established as
+ 'good'. In the following example command this is assumed to be 6.0; note that
+ the version number in this and all later Git commands needs to be prefixed
+ with a 'v'::
+
+ git switch --discard-changes --detach v6.0
+
+ Now create a build configuration file::
+
+ make olddefconfig
+
+ The kernel build scripts then will try to locate the build configuration file
+ for the running kernel and then adjust it for the needs of the kernel sources
+ you checked out. While doing so, it will print a few lines you need to check.
+
+ Look out for a line starting with '# using defaults found in'. It should be
+ followed by a path to a file in '/boot/' that contains the release identifier
+ of your currently working kernel. If the line instead continues with something
+ like 'arch/x86/configs/x86_64_defconfig', then the build infra failed to find
+ the .config file for your running kernel -- in which case you have to put one
+ there manually, as explained in the reference section.
+
+ In case you can not find such a line, look for one containing '# configuration
+ written to .config'. If that's the case you have a stale build configuration
+ lying around. Unless you intend to use it, delete it; afterwards run
+ 'make olddefconfig' again and check if it now picked up the right config file
+ as base.
+
+ [:ref:`details <oldconfig_bisref>`]
+
+.. _localmodconfig_bissbs:
+
+* Disable any kernel modules apparently superfluous for your setup. This is
+ optional, but especially wise for bisections, as it speeds up the build
+ process enormously -- at least unless the .config file picked up in the
+ previous step was already tailored to your and your hardware needs, in which
+ case you should skip this step.
+
+ To prepare the trimming, connect external hardware you occasionally use (USB
+ keys, tokens, ...), quickly start a VM, and bring up VPNs. And if you rebooted
+ since you started that guide, ensure that you tried using the feature causing
+ trouble since you started the system. Only then trim your .config::
+
+ yes '' | make localmodconfig
+
+ There is a catch to this, as the 'apparently' in initial sentence of this step
+ and the preparation instructions already hinted at:
+
+ The 'localmodconfig' target easily disables kernel modules for features only
+ used occasionally -- like modules for external peripherals not yet connected
+ since booting, virtualization software not yet utilized, VPN tunnels, and a
+ few other things. That's because some tasks rely on kernel modules Linux only
+ loads when you execute tasks like the aforementioned ones for the first time.
+
+ This drawback of localmodconfig is nothing you should lose sleep over, but
+ something to keep in mind: if something is misbehaving with the kernels built
+ during this guide, this is most likely the reason. You can reduce or nearly
+ eliminate the risk with tricks outlined in the reference section; but when
+ building a kernel just for quick testing purposes this is usually not worth
+ spending much effort on, as long as it boots and allows to properly test the
+ feature that causes trouble.
+
+ [:ref:`details <localmodconfig_bisref>`]
+
+.. _tagging_bissbs:
+
+* Ensure all the kernels you will build are clearly identifiable using a special
+ tag and a unique version number::
+
+ ./scripts/config --set-str CONFIG_LOCALVERSION '-local'
+ ./scripts/config -e CONFIG_LOCALVERSION_AUTO
+
+ [:ref:`details <tagging_bisref>`]
+
+.. _debugsymbols_bissbs:
+
+* Decide how to handle debug symbols.
+
+ In the context of this document it is often wise to enable them, as there is a
+ decent chance you will need to decode a stack trace from a 'panic', 'Oops',
+ 'warning', or 'BUG'::
+
+ ./scripts/config -d DEBUG_INFO_NONE -e KALLSYMS_ALL -e DEBUG_KERNEL \
+ -e DEBUG_INFO -e DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT -e KALLSYMS
+
+ But if you are extremely short on storage space, you might want to disable
+ debug symbols instead::
+
+ ./scripts/config -d DEBUG_INFO -d DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT \
+ -d DEBUG_INFO_DWARF4 -d DEBUG_INFO_DWARF5 -e CONFIG_DEBUG_INFO_NONE
+
+ [:ref:`details <debugsymbols_bisref>`]
+
+.. _configmods_bissbs:
+
+* Check if you may want or need to adjust some other kernel configuration
+ options:
+
+ * Are you running Debian? Then you want to avoid known problems by performing
+ additional adjustments explained in the reference section.
+
+ [:ref:`details <configmods_distros_bisref>`].
+
+ * If you want to influence other aspects of the configuration, do so now using
+ your preferred tool. Note, to use make targets like 'menuconfig' or
+ 'nconfig', you will need to install the development files of ncurses; for
+ 'xconfig' you likewise need the Qt5 or Qt6 headers.
+
+ [:ref:`details <configmods_individual_bisref>`].
+
+.. _saveconfig_bissbs:
+
+* Reprocess the .config after the latest adjustments and store it in a safe
+ place::
+
+ make olddefconfig
+ cp .config ~/kernel-config-working
+
+ [:ref:`details <saveconfig_bisref>`]
+
+.. _introlatestcheck_bissbs:
+
+Segment 1: try to reproduce the problem with the latest codebase
+----------------------------------------------------------------
+
+The following steps verify if the problem occurs with the code currently
+supported by developers. In case you face a regression, it also checks that the
+problem is not caused by some .config change, as reporting the issue then would
+be a waste of time. [:ref:`details <introlatestcheck_bisref>`]
+
+.. _checkoutmaster_bissbs:
+
+* Check out the latest Linux codebase.
+
+ * Are your 'good' and 'bad' versions from the same stable or longterm series?
+ Then check the `front page of kernel.org <https://kernel.org/>`_: if it
+ lists a release from that series without an '[EOL]' tag, checkout the series
+ latest version ('linux-6.1.y' in the following example)::
+
+ cd ~/linux/
+ git switch --discard-changes --detach stable/linux-6.1.y
+
+ Your series is unsupported, if is not listed or carrying a 'end of life'
+ tag. In that case you might want to check if a successor series (say
+ linux-6.2.y) or mainline (see next point) fix the bug.
+
+ * In all other cases, run::
+
+ cd ~/linux/
+ git switch --discard-changes --detach mainline/master
+
+ [:ref:`details <checkoutmaster_bisref>`]
+
+.. _build_bissbs:
+
+* Build the image and the modules of your first kernel using the config file you
+ prepared::
+
+ cp ~/kernel-config-working .config
+ make olddefconfig
+ make -j $(nproc --all)
+
+ If you want your kernel packaged up as deb, rpm, or tar file, see the
+ reference section for alternatives, which obviously will require other
+ steps to install as well.
+
+ [:ref:`details <build_bisref>`]
+
+.. _install_bissbs:
+
+* Install your newly built kernel.
+
+ Before doing so, consider checking if there is still enough space for it::
+
+ df -h /boot/ /lib/modules/
+
+ For now assume 150 MByte in /boot/ and 200 in /lib/modules/ will suffice; how
+ much your kernels actually require will be determined later during this guide.
+
+ Now install the kernel's modules and its image, which will be stored in
+ parallel to the your Linux distribution's kernels::
+
+ sudo make modules_install
+ command -v installkernel && sudo make install
+
+ The second command ideally will take care of three steps required at this
+ point: copying the kernel's image to /boot/, generating an initramfs, and
+ adding an entry for both to the boot loader's configuration.
+
+ Sadly some distributions (among them Arch Linux, its derivatives, and many
+ immutable Linux distributions) will perform none or only some of those tasks.
+ You therefore want to check if all of them were taken care of and manually
+ perform those that were not. The reference section provides further details on
+ that; your distribution's documentation might help, too.
+
+ Once you figured out the steps needed at this point, consider writing them
+ down: if you will build more kernels as described in segment 2 and 3, you will
+ have to perform those again after executing ``command -v installkernel [...]``.
+
+ [:ref:`details <install_bisref>`]
+
+.. _storagespace_bissbs:
+
+* In case you plan to follow this guide further, check how much storage space
+ the kernel, its modules, and other related files like the initramfs consume::
+
+ du -ch /boot/*$(make -s kernelrelease)* | tail -n 1
+ du -sh /lib/modules/$(make -s kernelrelease)/
+
+ Write down or remember those two values for later: they enable you to prevent
+ running out of disk space accidentally during a bisection.
+
+ [:ref:`details <storagespace_bisref>`]
+
+.. _kernelrelease_bissbs:
+
+* Show and store the kernelrelease identifier of the kernel you just built::
+
+ make -s kernelrelease | tee -a ~/kernels-built
+
+ Remember the identifier momentarily, as it will help you pick the right kernel
+ from the boot menu upon restarting.
+
+* Reboot into your newly built kernel. To ensure your actually started the one
+ you just built, you might want to verify if the output of these commands
+ matches::
+
+ tail -n 1 ~/kernels-built
+ uname -r
+
+.. _tainted_bissbs:
+
+* Check if the kernel marked itself as 'tainted'::
+
+ cat /proc/sys/kernel/tainted
+
+ If that command does not return '0', check the reference section, as the cause
+ for this might interfere with your testing.
+
+ [:ref:`details <tainted_bisref>`]
+
+.. _recheckbroken_bissbs:
+
+* Verify if your bug occurs with the newly built kernel. If it does not, check
+ out the instructions in the reference section to ensure nothing went sideways
+ during your tests.
+
+ [:ref:`details <recheckbroken_bisref>`]
+
+.. _recheckstablebroken_bissbs:
+
+* Did you just built a stable or longterm kernel? And were you able to reproduce
+ the regression with it? Then you should test the latest mainline codebase as
+ well, because the result determines which developers the bug must be submitted
+ to.
+
+ To prepare that test, check out current mainline::
+
+ cd ~/linux/
+ git switch --discard-changes --detach mainline/master
+
+ Now use the checked out code to build and install another kernel using the
+ commands the earlier steps already described in more detail::
+
+ cp ~/kernel-config-working .config
+ make olddefconfig
+ make -j $(nproc --all)
+ # * Check if the free space suffices holding another kernel:
+ df -h /boot/ /lib/modules/
+ sudo make modules_install
+ command -v installkernel && sudo make install
+ make -s kernelrelease | tee -a ~/kernels-built
+ reboot
+
+ Confirm you booted the kernel you intended to start and check its tainted
+ status::
+
+ tail -n 1 ~/kernels-built
+ uname -r
+ cat /proc/sys/kernel/tainted
+
+ Now verify if this kernel is showing the problem. If it does, then you need
+ to report the bug to the primary developers; if it does not, report it to the
+ stable team. See Documentation/admin-guide/reporting-issues.rst for details.
+
+ [:ref:`details <recheckstablebroken_bisref>`]
+
+Do you follow this guide to verify if a problem is present in the code
+currently supported by Linux kernel developers? Then you are done at this
+point. If you later want to remove the kernel you just built, check out
+:ref:`Complementary tasks: cleanup during and after following this guide <introclosure_bissbs>`.
+
+In case you face a regression, move on and execute at least the next segment
+as well.
+
+.. _introworkingcheck_bissbs:
+
+Segment 2: check if the kernels you build work fine
+---------------------------------------------------
+
+In case of a regression, you now want to ensure the trimmed configuration file
+you created earlier works as expected; a bisection with the .config file
+otherwise would be a waste of time. [:ref:`details <introworkingcheck_bisref>`]
+
+.. _recheckworking_bissbs:
+
+* Build your own variant of the 'working' kernel and check if the feature that
+ regressed works as expected with it.
+
+ Start by checking out the sources for the version earlier established as
+ 'good' (once again assumed to be 6.0 here)::
+
+ cd ~/linux/
+ git switch --discard-changes --detach v6.0
+
+ Now use the checked out code to configure, build, and install another kernel
+ using the commands the previous subsection explained in more detail::
+
+ cp ~/kernel-config-working .config
+ make olddefconfig
+ make -j $(nproc --all)
+ # * Check if the free space suffices holding another kernel:
+ df -h /boot/ /lib/modules/
+ sudo make modules_install
+ command -v installkernel && sudo make install
+ make -s kernelrelease | tee -a ~/kernels-built
+ reboot
+
+ When the system booted, you may want to verify once again that the
+ kernel you started is the one you just built::
+
+ tail -n 1 ~/kernels-built
+ uname -r
+
+ Now check if this kernel works as expected; if not, consult the reference
+ section for further instructions.
+
+ [:ref:`details <recheckworking_bisref>`]
+
+.. _introbisect_bissbs:
+
+Segment 3: perform the bisection and validate the result
+--------------------------------------------------------
+
+With all the preparations and precaution builds taken care of, you are now ready
+to begin the bisection. This will make you build quite a few kernels -- usually
+about 15 in case you encountered a regression when updating to a newer series
+(say from 6.0.13 to 6.1.5). But do not worry, due to the trimmed build
+configuration created earlier this works a lot faster than many people assume:
+overall on average it will often just take about 10 to 15 minutes to compile
+each kernel on commodity x86 machines.
+
+.. _bisectstart_bissbs:
+
+* Start the bisection and tell Git about the versions earlier established as
+ 'good' (6.0 in the following example command) and 'bad' (6.1.5)::
+
+ cd ~/linux/
+ git bisect start
+ git bisect good v6.0
+ git bisect bad v6.1.5
+
+ [:ref:`details <bisectstart_bisref>`]
+
+.. _bisectbuild_bissbs:
+
+* Now use the code Git checked out to build, install, and boot a kernel using
+ the commands introduced earlier::
+
+ cp ~/kernel-config-working .config
+ make olddefconfig
+ make -j $(nproc --all)
+ # * Check if the free space suffices holding another kernel:
+ df -h /boot/ /lib/modules/
+ sudo make modules_install
+ command -v installkernel && sudo make install
+ make -s kernelrelease | tee -a ~/kernels-built
+ reboot
+
+ If compilation fails for some reason, run ``git bisect skip`` and restart
+ executing the stack of commands from the beginning.
+
+ In case you skipped the 'test latest codebase' step in the guide, check its
+ description as for why the 'df [...]' and 'make -s kernelrelease [...]'
+ commands are here.
+
+ Important note: the latter command from this point on will print release
+ identifiers that might look odd or wrong to you -- which they are not, as it's
+ totally normal to see release identifiers like '6.0-rc1-local-gcafec0cacaca0'
+ if you bisect between versions 6.1 and 6.2 for example.
+
+ [:ref:`details <bisectbuild_bisref>`]
+
+.. _bisecttest_bissbs:
+
+* Now check if the feature that regressed works in the kernel you just built.
+
+ You again might want to start by making sure the kernel you booted is the one
+ you just built::
+
+ cd ~/linux/
+ tail -n 1 ~/kernels-built
+ uname -r
+
+ Now verify if the feature that regressed works at this kernel bisection point.
+ If it does, run this::
+
+ git bisect good
+
+ If it does not, run this::
+
+ git bisect bad
+
+ Be sure about what you tell Git, as getting this wrong just once will send the
+ rest of the bisection totally off course.
+
+ While the bisection is ongoing, Git will use the information you provided to
+ find and check out another bisection point for you to test. While doing so, it
+ will print something like 'Bisecting: 675 revisions left to test after this
+ (roughly 10 steps)' to indicate how many further changes it expects to be
+ tested. Now build and install another kernel using the instructions from the
+ previous step; afterwards follow the instructions in this step again.
+
+ Repeat this again and again until you finish the bisection -- that's the case
+ when Git after tagging a change as 'good' or 'bad' prints something like
+ 'cafecaca0c0dacafecaca0c0dacafecaca0c0da is the first bad commit'; right
+ afterwards it will show some details about the culprit including the patch
+ description of the change. The latter might fill your terminal screen, so you
+ might need to scroll up to see the message mentioning the culprit;
+ alternatively, run ``git bisect log > ~/bisection-log``.
+
+ [:ref:`details <bisecttest_bisref>`]
+
+.. _bisectlog_bissbs:
+
+* Store Git's bisection log and the current .config file in a safe place before
+ telling Git to reset the sources to the state before the bisection::
+
+ cd ~/linux/
+ git bisect log > ~/bisection-log
+ cp .config ~/bisection-config-culprit
+ git bisect reset
+
+ [:ref:`details <bisectlog_bisref>`]
+
+.. _revert_bissbs:
+
+* Try reverting the culprit on top of latest mainline to see if this fixes your
+ regression.
+
+ This is optional, as it might be impossible or hard to realize. The former is
+ the case, if the bisection determined a merge commit as the culprit; the
+ latter happens if other changes depend on the culprit. But if the revert
+ succeeds, it is worth building another kernel, as it validates the result of
+ a bisection, which can easily deroute; it furthermore will let kernel
+ developers know, if they can resolve the regression with a quick revert.
+
+ Begin by checking out the latest codebase depending on the range you bisected:
+
+ * Did you face a regression within a stable/longterm series (say between
+ 6.0.13 and 6.0.15) that does not happen in mainline? Then check out the
+ latest codebase for the affected series like this::
+
+ git fetch stable
+ git switch --discard-changes --detach linux-6.0.y
+
+ * In all other cases check out latest mainline::
+
+ git fetch mainline
+ git switch --discard-changes --detach mainline/master
+
+ If you bisected a regression within a stable/longterm series that also
+ happens in mainline, there is one more thing to do: look up the mainline
+ commit-id. To do so, use a command like ``git show abcdcafecabcd`` to
+ view the patch description of the culprit. There will be a line near
+ the top which looks like 'commit cafec0cacaca0 upstream.' or
+ 'Upstream commit cafec0cacaca0'; use that commit-id in the next command
+ and not the one the bisection blamed.
+
+ Now try reverting the culprit by specifying its commit id::
+
+ git revert --no-edit cafec0cacaca0
+
+ If that fails, give up trying and move on to the next step; if it works,
+ adjust the tag to facilitate the identification and prevent accidentally
+ overwriting another kernel::
+
+ cp ~/kernel-config-working .config
+ ./scripts/config --set-str CONFIG_LOCALVERSION '-local-cafec0cacaca0-reverted'
+
+ Build a kernel using the familiar command sequence, just without copying the
+ the base .config over::
+
+ make olddefconfig &&
+ make -j $(nproc --all)
+ # * Check if the free space suffices holding another kernel:
+ df -h /boot/ /lib/modules/
+ sudo make modules_install
+ command -v installkernel && sudo make install
+ make -s kernelrelease | tee -a ~/kernels-built
+ reboot
+
+ Now check one last time if the feature that made you perform a bisection works
+ with that kernel: if everything went well, it should not show the regression.
+

+
+.. _introclosure_bissbs:
+
+Complementary tasks: cleanup during and after the bisection
+-----------------------------------------------------------
+
+During and after following this guide you might want or need to remove some of
+the kernels you installed: the boot menu otherwise will become confusing or
+space might run out.
+
+.. _makeroom_bissbs:
+
+* To remove one of the kernels you installed, look up its 'kernelrelease'
+ identifier. This guide stores them in '~/kernels-built', but the following
+ command will print them as well::
+
+ ls -ltr /lib/modules/*-local*
+
+ You in most situations want to remove the oldest kernels built during the
+ actual bisection (e.g. segment 3 of this guide). The two ones you created
+ beforehand (e.g. to test the latest codebase and the version considered
+ 'good') might become handy to verify something later -- thus better keep them
+ around, unless you are really short on storage space.
+
+ To remove the modules of a kernel with the kernelrelease identifier
+ '*6.0-rc1-local-gcafec0cacaca0*', start by removing the directory holding its
+ modules::
+
+ sudo rm -rf /lib/modules/6.0-rc1-local-gcafec0cacaca0
+
+ Afterwards try the following command::
+
+ sudo kernel-install -v remove 6.0-rc1-local-gcafec0cacaca0
+
+ On quite a few distributions this will delete all other kernel files installed
+ while also removing the kernel's entry from the boot menu. But on some
+ distributions kernel-install does not exist or leaves boot-loader entries or
+ kernel image and related files behind; in that case remove them as described
+ in the reference section.
+
+ [:ref:`details <makeroom_bisref>`]
+
+.. _finishingtouch_bissbs:
+
+* Once you have finished the bisection, do not immediately remove anything you
+ set up, as you might need a few things again. What is safe to remove depends
+ on the outcome of the bisection:
+
+ * Could you initially reproduce the regression with the latest codebase and
+ after the bisection were able to fix the problem by reverting the culprit on
+ top of the latest codebase? Then you want to keep those two kernels around
+ for a while, but safely remove all others with a '-local' in the release
+ identifier.
+
+ * Did the bisection end on a merge-commit or seems questionable for other
+ reasons? Then you want to keep as many kernels as possible around for a few
+ days: it's pretty likely that you will be asked to recheck something.
+
+ * In other cases it likely is a good idea to keep the following kernels around
+ for some time: the one built from the latest codebase, the one created from
+ the version considered 'good', and the last three or four you compiled
+ during the actual bisection process.
+
+ [:ref:`details <finishingtouch_bisref>`]
+
+.. _introoptional_bissbs:
+
+Optional: test reverts, patches, or later versions
+--------------------------------------------------
+
+While or after reporting a bug, you might want or potentially will be asked to
+test reverts, debug patches, proposed fixes, or other versions. In that case
+follow these instructions.
+
+* Update your Git clone and check out the latest code.
+
+ * In case you want to test mainline, fetch its latest changes before checking
+ its code out::
+
+ git fetch mainline
+ git switch --discard-changes --detach mainline/master
+
+ * In case you want to test a stable or longterm kernel, first add the branch
+ holding the series you are interested in (6.2 in the example), unless you
+ already did so earlier::
+
+ git remote set-branches --add stable linux-6.2.y
+
+ Then fetch the latest changes and check out the latest version from the
+ series::
+
+ git fetch stable
+ git switch --discard-changes --detach stable/linux-6.2.y
+
+* Copy your kernel build configuration over::
+
+ cp ~/kernel-config-working .config
+
+* Your next step depends on what you want to do:
+
+ * In case you just want to test the latest codebase, head to the next step,
+ you are already all set.
+
+ * In case you want to test if a revert fixes an issue, revert one or multiple
+ changes by specifying their commit ids::
+
+ git revert --no-edit cafec0cacaca0
+
+ Now give that kernel a special tag to facilitates its identification and
+ prevent accidentally overwriting another kernel::
+
+ ./scripts/config --set-str CONFIG_LOCALVERSION '-local-cafec0cacaca0-reverted'
+
+ * In case you want to test a patch, store the patch in a file like
+ '/tmp/foobars-proposed-fix-v1.patch' and apply it like this::
+
+ git apply /tmp/foobars-proposed-fix-v1.patch
+
+ In case of multiple patches, repeat this step with the others.
+
+ Now give that kernel a special tag to facilitates its identification and
+ prevent accidentally overwriting another kernel::
+
+ ./scripts/config --set-str CONFIG_LOCALVERSION '-local-foobars-fix-v1'
+
+* Build a kernel using the familiar commands, just without copying the kernel
+ build configuration over, as that has been taken care of already::
+
+ make olddefconfig &&
+ make -j $(nproc --all)
+ # * Check if the free space suffices holding another kernel:
+ df -h /boot/ /lib/modules/
+ sudo make modules_install
+ command -v installkernel && sudo make install
+ make -s kernelrelease | tee -a ~/kernels-built
+ reboot
+
+* Now verify you booted the newly built kernel and check it.

+
+Reference section for the step-by-step guide
+============================================
+
+This section holds additional information for almost all the items in the above
+step-by-step guide.
+
+Preparations for building your own kernels
+------------------------------------------
+
+ *The steps in this section lay the groundwork for all further tests.*
+ [:ref:`... <introprep_bissbs>`]
+
+The steps in all later sections of this guide depend on those described here.
+
+[:ref:`back to step-by-step guide <introprep_bissbs>`].
+
+.. _backup_bisref:
+
+Prepare for emergencies
+~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Create a fresh backup and put system repair and restore tools at hand.*
+ [:ref:`... <backup_bissbs>`]
+
+Remember, you are dealing with computers, which sometimes do unexpected things
+-- especially if you fiddle with crucial parts like the kernel of an operating
+system. That's what you are about to do in this process. Hence, better prepare
+for something going sideways, even if that should not happen.
+
+[:ref:`back to step-by-step guide <backup_bissbs>`]
+
+.. _vanilla_bisref:
+
+Remove anything related to externally maintained kernel modules
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Remove all software that depends on externally developed kernel drivers or
+ builds them automatically.* [:ref:`...<vanilla_bissbs>`]
+
+Externally developed kernel modules can easily cause trouble during a bisection.
+
+But there is a more important reason why this guide contains this step: most
+kernel developers will not care about reports about regressions occurring with
+kernels that utilize such modules. That's because such kernels are not
+considered 'vanilla' anymore, as Documentation/admin-guide/reporting-issues.rst
+explains in more detail.
+
+[:ref:`back to step-by-step guide <vanilla_bissbs>`]
+
+.. _secureboot_bisref:
+
+Deal with techniques like Secure Boot
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *On platforms with 'Secure Boot' or similar techniques, prepare everything to
+ ensure the system will permit your self-compiled kernel to boot later.*
+ [:ref:`... <secureboot_bissbs>`]
+
+Many modern systems allow only certain operating systems to start; that's why
+they reject booting self-compiled kernels by default.
+
+You ideally deal with this by making your platform trust your self-built kernels
+with the help of a certificate. How to do that is not described
+here, as it requires various steps that would take the text too far away from
+its purpose; 'Documentation/admin-guide/module-signing.rst' and various web
+sides already explain everything needed in more detail.
+
+Temporarily disabling solutions like Secure Boot is another way to make your own
+Linux boot. On commodity x86 systems it is possible to do this in the BIOS Setup
+utility; the required steps vary a lot between machines and therefore cannot be
+described here.
+
+On mainstream x86 Linux distributions there is a third and universal option:
+disable all Secure Boot restrictions for your Linux environment. You can
+initiate this process by running ``mokutil --disable-validation``; this will
+tell you to create a one-time password, which is safe to write down. Now
+restart; right after your BIOS performed all self-tests the bootloader Shim will
+show a blue box with a message 'Press any key to perform MOK management'. Hit
+some key before the countdown exposes, which will open a menu. Choose 'Change
+Secure Boot state'. Shim's 'MokManager' will now ask you to enter three
+randomly chosen characters from the one-time password specified earlier. Once
+you provided them, confirm you really want to disable the validation.
+Afterwards, permit MokManager to reboot the machine.
+

+
+.. _bootworking_bisref:
+
+Boot the last kernel that was working
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Boot into the last working kernel and briefly recheck if the feature that
+ regressed really works.* [:ref:`...<bootworking_bissbs>`]
+
+This will make later steps that cover creating and trimming the configuration do
+the right thing.
+
+[:ref:`back to step-by-step guide <bootworking_bissbs>`]
+
+.. _diskspace_bisref:
+
+Space requirements
+~~~~~~~~~~~~~~~~~~
+
+ *Ensure to have enough free space for building Linux.*
+ [:ref:`... <diskspace_bissbs>`]
+
+The numbers mentioned are rough estimates with a big extra charge to be on the
+safe side, so often you will need less.
+
+If you have space constraints, be sure to hay attention to the :ref:`step about
+debug symbols' <debugsymbols_bissbs>` and its :ref:`accompanying reference
+section' <debugsymbols_bisref>`, as disabling then will reduce the consumed disk
+space by quite a few gigabytes.
+
+[:ref:`back to step-by-step guide <diskspace_bissbs>`]
+
+.. _rangecheck_bisref:
+
+Bisection range
+~~~~~~~~~~~~~~~
+
+ *Determine the kernel versions considered 'good' and 'bad' throughout this
+ guide.* [:ref:`...<rangecheck_bissbs>`]
+
+Establishing the range of commits to be checked is mostly straightforward,
+except when a regression occurred when switching from a release of one stable
+series to a release of a later series (e.g. from 6.0.13 to 6.1.5). In that case
+Git will need some hand holding, as there is no straight line of descent.
+
+That's because with the release of 6.0 mainline carried on to 6.1 while the
+stable series 6.0.y branched to the side. It's therefore theoretically possible
+that the issue you face with 6.1.5 only worked in 6.0.13, as it was fixed by a
+commit that went into one of the 6.0.y releases, but never hit mainline or the
+6.1.y series. Thankfully that normally should not happen due to the way the
+stable/longterm maintainers maintain the code. It's thus pretty safe to assume
+6.0 as a 'good' kernel. That assumption will be tested anyway, as that kernel
+will be built and tested in the segment '2' of this guide; Git would force you
+to do this as well, if you tried bisecting between 6.0.13 and 6.1.15.
+
+[:ref:`back to step-by-step guide <rangecheck_bissbs>`]
+
+.. _buildrequires_bisref:
+
+Install build requirements
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Install all software required to build a Linux kernel.*
+ [:ref:`...<buildrequires_bissbs>`]
+
+The kernel is pretty stand-alone, but besides tools like the compiler you will
+sometimes need a few libraries to build one. How to install everything needed
+depends on your Linux distribution and the configuration of the kernel you are
+about to build.
+
+Here are a few examples what you typically need on some mainstream
+distributions:
+
+* Arch Linux and derivatives::
+
+ sudo pacman --needed -S bc binutils bison flex gcc git kmod libelf openssl \
+ pahole perl zlib ncurses qt6-base
+
+* Debian, Ubuntu, and derivatives::
+
+ sudo apt install bc binutils bison dwarves flex gcc git kmod libelf-dev \
+ libssl-dev make openssl pahole perl-base pkg-config zlib1g-dev \
+ libncurses-dev qt6-base-dev g++
+
+* Fedora and derivatives::
+
+ sudo dnf install binutils \
+ /usr/bin/{bc,bison,flex,gcc,git,openssl,make,perl,pahole,rpmbuild} \
+ /usr/include/{libelf.h,openssl/pkcs7.h,zlib.h,ncurses.h,qt6/QtGui/QAction}
+
+* openSUSE and derivatives::
+
+ sudo zypper install bc binutils bison dwarves flex gcc git \
+ kernel-install-tools libelf-devel make modutils openssl openssl-devel \
+ perl-base zlib-devel rpm-build ncurses-devel qt6-base-devel
+
+These commands install a few packages that are often, but not always needed. You
+for example might want to skip installing the development headers for ncurses,
+which you will only need in case you later might want to adjust the kernel build
+configuration using make the targets 'menuconfig' or 'nconfig'; likewise omit
+the headers of Qt6 if you do not plan to adjust the .config using 'xconfig'.
+
+You furthermore might need additional libraries and their development headers
+for tasks not covered in this guide -- for example when building utilities from
+the kernel's tools/ directory.
+
+[:ref:`back to step-by-step guide <buildrequires_bissbs>`]
+
+.. _sources_bisref:
+
+Download the sources using Git
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Retrieve the Linux mainline sources.*
+ [:ref:`...<sources_bissbs>`]
+
+The step-by-step guide outlines how to download the Linux sources using a full
+Git clone of Linus' mainline repository. There is nothing more to say about
+that -- but there are two alternatives ways to retrieve the sources that might
+work better for you:
+
+* If you have an unreliable internet connection, consider
+ :ref:`using a 'Git bundle'<sources_bundle_bisref>`.
+
+* If downloading the complete repository would take too long or requires too
+ much storage space, consider :ref:`using a 'shallow
+ clone'<sources_shallow_bisref>`.
+
+.. _sources_bundle_bisref:
+
+Downloading Linux mainline sources using a bundle
+"""""""""""""""""""""""""""""""""""""""""""""""""
+
+Use the following commands to retrieve the Linux mainline sources using a
+bundle::
+
+ wget -c \
+ https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/clone.bundle
+ git clone --no-checkout clone.bundle ~/linux/
+ cd ~/linux/
+ git remote remove origin
+ git remote add mainline \
+ https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
+ git fetch mainline
+ git remote add -t master stable \
+ https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
+
+In case the 'wget' command fails, just re-execute it, it will pick up where
+it left off.
+
+[:ref:`back to step-by-step guide <sources_bissbs>`]
+[:ref:`back to section intro <sources_bisref>`]
+
+.. _sources_shallow_bisref:
+
+Downloading Linux mainline sources using a shallow clone
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+First, execute the following command to retrieve the latest mainline codebase::
+
+ git clone -o mainline --no-checkout --depth 1 -b master \
+ https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git ~/linux/
+ cd ~/linux/
+ git remote add -t master stable \
+ https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
+
+Now deepen your clone's history to the second predecessor of the mainline
+release of your 'good' version. In case the latter are 6.0 or 6.0.13, 5.19 would
+be the first predecessor and 5.18 the second -- hence deepen the history up to
+that version::
+
+ git fetch --shallow-exclude=v5.18 mainline
+
+Afterwards add the stable Git repository as remote and all required stable
+branches as explained in the step-by-step guide.
+
+Note, shallow clones have a few peculiar characteristics:
+
+* For bisections the history needs to be deepened a few mainline versions
+ farther than it seems necessary, as explained above already. That's because
+ Git otherwise will be unable to revert or describe most of the commits within
+ a range (say 6.1..6.2), as they are internally based on earlier kernels
+ releases (like 6.0-rc2 or 5.19-rc3).
+
+* This document in most places uses ``git fetch`` with ``--shallow-exclude=``
+ to specify the earliest version you care about (or to be precise: its git
+ tag). You alternatively can use the parameter ``--shallow-since=`` to specify
+ an absolute (say ``'2023-07-15'``) or relative (``'12 months'``) date to
+ define the depth of the history you want to download. When using them while
+ bisecting mainline, ensure to deepen the history to at least 7 months before
+ the release of the mainline release your 'good' kernel is based on.
+
+* Be warned, when deepening your clone you might encounter an error like
+ 'fatal: error in object: unshallow cafecaca0c0dacafecaca0c0dacafecaca0c0da'.
+ In that case run ``git repack -d`` and try again.
+
+[:ref:`back to step-by-step guide <sources_bissbs>`]
+[:ref:`back to section intro <sources_bisref>`]
+
+.. _oldconfig_bisref:
+
+Start defining the build configuration for your kernel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Start preparing a kernel build configuration (the '.config' file).*
+ [:ref:`... <oldconfig_bissbs>`]
+
+*Note, this is the first of multiple steps in this guide that create or modify
+build artifacts. The commands used in this guide store them right in the source
+tree to keep things simple. In case you prefer storing the build artifacts
+separately, create a directory like '~/linux-builddir/' and add the parameter
+``O=~/linux-builddir/`` to all make calls used throughout this guide. You will
+have to point other commands there as well -- among them the ``./scripts/config
+[...]`` commands, which will require ``--file ~/linux-builddir/.config`` to
+locate the right build configuration.*
+
+Two things can easily go wrong when creating a .config file as advised:
+
+* The oldconfig target will use a .config file from your build directory, if
+ one is already present there (e.g. '~/linux/.config'). That's totally fine if
+ that's what you intend (see next step), but in all other cases you want to
+ delete it. This for example is important in case you followed this guide
+ further, but due to problems come back here to redo the configuration from
+ scratch.
+
+* Sometimes olddefconfig is unable to locate the .config file for your running
+ kernel and will use defaults, as briefly outlined in the guide. In that case
+ check if your distribution ships the configuration somewhere and manually put
+ it in the right place (e.g. '~/linux/.config') if it does. On distributions
+ where /proc/config.gz exists this can be achieved using this command::
+
+ zcat /proc/config.gz > .config
+
+ Once you put it there, run ``make olddefconfig`` again to adjust it to the
+ needs of the kernel about to be built.
+
+Note, the olddefconfig target will set any undefined build options to their
+default value. If you prefer to set such configuration options manually, use
+``make oldconfig`` instead. Then for each undefined configuration option you
+will be asked how to proceed; in case you are unsure what to answer, simply hit
+'enter' to apply the default value. Note though that for bisections you normally
+want to go with the defaults, as you otherwise might enable a new feature that
+causes a problem looking like regressions (for example due to security
+restrictions).
+
+Occasionally odd things happen when trying to use a config file prepared for one
+kernel (say 6.1) on an older mainline release -- especially if it is much older
+(say 5.15). That's one of the reasons why the previous step in the guide told
+you to boot the kernel where everything works. If you manually add a .config
+file you thus want to ensure it's from the working kernel and not from a one
+that shows the regression.
+
+In case you want to build kernels for another machine, locate its kernel build
+configuration; usually ``ls /boot/config-$(uname -r)`` will print its name. Copy
+that file to the build machine and store it as ~/linux/.config; afterwards run
+``make olddefconfig`` to adjust it.
+
+[:ref:`back to step-by-step guide <oldconfig_bissbs>`]
+
+.. _localmodconfig_bisref:
+
+Trim the build configuration for your kernel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Disable any kernel modules apparently superfluous for your setup.*
+ [:ref:`... <localmodconfig_bissbs>`]
+
+As explained briefly in the step-by-step guide already: with localmodconfig it
+can easily happen that your self-built kernels will lack modules for tasks you
+did not perform at least once before utilizing this make target. That happens
+when a task requires kernel modules which are only autoloaded when you execute
+it for the first time. So when you never performed that task since starting your
+kernel the modules will not have been loaded -- and from localmodconfig's point
+of view look superfluous, which thus disables them to reduce the amount of code
+to be compiled.
+
+You can try to avoid this by performing typical tasks that often will autoload
+additional kernel modules: start a VM, establish VPN connections, loop-mount a
+CD/DVD ISO, mount network shares (CIFS, NFS, ...), and connect all external
+devices (2FA keys, headsets, webcams, ...) as well as storage devices with file
+systems you otherwise do not utilize (btrfs, ext4, FAT, NTFS, XFS, ...). But it
+is hard to think of everything that might be needed -- even kernel developers
+often forget one thing or another at this point.
+
+Do not let that risk bother you, especially when compiling a kernel only for
+testing purposes: everything typically crucial will be there. And if you forget
+something important you can turn on a missing feature manually later and quickly
+run the commands again to compile and install a kernel that has everything you
+need.
+
+But if you plan to build and use self-built kernels regularly, you might want to
+reduce the risk by recording which modules your system loads over the course of
+a few weeks. You can automate this with `modprobed-db
+<https://github.com/graysky2/modprobed-db>`_. Afterwards use ``LSMOD=<path>`` to
+point localmodconfig to the list of modules modprobed-db noticed being used::
+
+ yes '' | make LSMOD='${HOME}'/.config/modprobed.db localmodconfig
+
+That parameter also allows you to build trimmed kernels for another machine in
+case you copied a suitable .config over to use as base (see previous step). Just
+run ``lsmod > lsmod_foo-machine`` on that system and copy the generated file to
+your build's host home directory. Then run these commands instead of the one the
+step-by-step guide mentions::
+
+ yes '' | make LSMOD=~/lsmod_foo-machine localmodconfig
+
+[:ref:`back to step-by-step guide <localmodconfig_bissbs>`]
+
+.. _tagging_bisref:
+
+Tag the kernels about to be build
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Ensure all the kernels you will build are clearly identifiable using a
+ special tag and a unique version identifier.* [:ref:`... <tagging_bissbs>`]
+
+This allows you to differentiate your distribution's kernels from those created
+during this process, as the file or directories for the latter will contain
+'-local' in the name; it also helps picking the right entry in the boot menu and
+not lose track of you kernels, as their version numbers will look slightly
+confusing during the bisection.
+
+[:ref:`back to step-by-step guide <tagging_bissbs>`]
+
+.. _debugsymbols_bisref:
+
+Decide to enable or disable debug symbols
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Decide how to handle debug symbols.* [:ref:`... <debugsymbols_bissbs>`]
+
+Having debug symbols available can be important when your kernel throws a
+'panic', 'Oops', 'warning', or 'BUG' later when running, as then you will be
+able to find the exact place where the problem occurred in the code. But
+collecting and embedding the needed debug information takes time and consumes
+quite a bit of space: in late 2022 the build artifacts for a typical x86 kernel
+trimmed with localmodconfig consumed around 5 Gigabyte of space with debug
+symbols, but less than 1 when they were disabled. The resulting kernel image and
+modules are bigger as well, which increases storage requirements for /boot/ and
+load times.
+
+In case you want a small kernel and are unlikely to decode a stack trace later,
+you thus might want to disable debug symbols to avoid those downsides. If it
+later turns out that you need them, just enable them as shown and rebuild the
+kernel.
+
+You on the other hand definitely want to enable them for this process, if there
+is a decent chance that you need to decode a stack trace later. The section
+'Decode failure messages' in Documentation/admin-guide/reporting-issues.rst
+explains this process in more detail.

+ [:ref:`... <saveconfig_bissbs>`]
+
+Put the .config you prepared aside, as you want to copy it back to the build
+directory every time during this guide before you start building another
+kernel. That's because going back and forth between different versions can alter
+.config files in odd ways; those occasionally cause side effects that could
+confuse testing or in some cases render the result of your bisection
+meaningless.

+.. _introlatestcheck_bisref:
+
+Try to reproduce the problem with the latest codebase
+-----------------------------------------------------
+
+ *Verify the regression is not caused by some .config change and check if it
+ still occurs with the latest codebase.* [:ref:`... <introlatestcheck_bissbs>`]
+
+For some readers it might seem unnecessary to check the latest codebase at this
+point, especially if you did that already with a kernel prepared by your
+distributor or face a regression within a stable/longterm series. But it's
+highly recommended for these reasons:
+
+* You will run into any problems caused by your setup before you actually begin
+ a bisection. That will make it a lot easier to differentiate between 'this
+ most likely is some problem in my setup' and 'this change needs to be skipped
+ during the bisection, as the kernel sources at that stage contain an unrelated
+ problem that causes building or booting to fail'.
+
+* These steps will rule out if your problem is caused by some change in the
+ build configuration between the 'working' and the 'broken' kernel. This for
+ example can happen when your distributor enabled an additional security
+ feature in the newer kernel which was disabled or not yet supported by the
+ older kernel. That security feature might get into the way of something you
+ do -- in which case your problem from the perspective of the Linux kernel
+ upstream developers is not a regression, as
+ Documentation/admin-guide/reporting-regressions.rst explains in more detail.
+ You thus would waste your time if you'd try to bisect this.
+
+* If the cause for your regression was already fixed in the latest mainline
+ codebase, you'd perform the bisection for nothing. This holds true for a
+ regression you encountered with a stable/longterm release as well, as they are
+ often caused by problems in mainline changes that were backported -- in which
+ case the problem will have to be fixed in mainline first. Maybe it already was
+ fixed there and the fix is already in the process of being backported.
+
+* For regressions within a stable/longterm series it's furthermore crucial to
+ know if the issue is specific to that series or also happens in the mainline
+ kernel, as the report needs to be sent to different people:
+
+ * Regressions specific to a stable/longterm series are the stable team's
+ responsibility; mainline Linux developers might or might not care.
+
+ * Regressions also happening in mainline are something the regular Linux
+ developers and maintainers have to handle; the stable team does not care
+ and does not need to be involved in the report, they just should be told
+ to backport the fix once it's ready.
+
+ Your report might be ignored if you send it to the wrong party -- and even
+ when you get a reply there is a decent chance that developers tell you to
+ evaluate which of the two cases it is before they take a closer look.

+deb, rpm or tar file.
+
+Dealing with build errors
+"""""""""""""""""""""""""
+
+When a build error occurs, it might be caused by some aspect of your machine's
+setup that often can be fixed quickly; other times though the problem lies in
+the code and can only be fixed by a developer. A close examination of the
+failure messages coupled with some research on the internet will often tell you
+which of the two it is. To perform such investigation, restart the build
+process like this::
+
+ make V=1
+
+The ``V=1`` activates verbose output, which might be needed to see the actual
+error. To make it easier to spot, this command also omits the ``-j $(nproc
+--all)`` used earlier to utilize every CPU core in the system for the job -- but
+this parallelism also results in some clutter when failures occur.
+
+After a few seconds the build process should run into the error again. Now try
+to find the most crucial line describing the problem. Then search the internet
+for the most important and non-generic section of that line (say 4 to 8 words);
+avoid or remove anything that looks remotely system-specific, like your username
+or local path names like ``/home/username/linux/``. First try your regular
+internet search engine with that string, afterwards search Linux kernel mailing
+lists via `lore.kernel.org/all/ <https://lore.kernel.org/all/>`_.
+
+This most of the time will find something that will explain what is wrong; quite
+often one of the hits will provide a solution for your problem, too. If you
+do not find anything that matches your problem, try again from a different angle
+by modifying your search terms or using another line from the error messages.
+
+In the end, most issues you run into have likely been encountered and
+reported by others already. That includes issues where the cause is not your
+system, but lies in the code. If you run into one of those, you might thus find
+a solution (e.g. a patch) or workaround for your issue, too.
+
+Package your kernel up
+""""""""""""""""""""""
+
+The step-by-step guide uses the default make targets (e.g. 'bzImage' and
+'modules' on x86) to build the image and the modules of your kernel, which later
+steps of the guide then install. You instead can also directly build everything
+and directly package it up by using one of the following targets:
+
+* ``make -j $(nproc --all) bindeb-pkg`` to generate a deb package
+
+* ``make -j $(nproc --all) binrpm-pkg`` to generate a rpm package
+
+* ``make -j $(nproc --all) tarbz2-pkg`` to generate a bz2 compressed tarball
+
+This is just a selection of available make targets for this purpose, see
+``make help`` for others. You can also use these targets after running
+``make -j $(nproc --all)``, as they will pick up everything already built.
+
+If you employ the targets to generate deb or rpm packages, ignore the
+step-by-step guide's instructions on installing and removing your kernel;
+instead install and remove the packages using the package utility for the format
+(e.g. dpkg and rpm) or a package management utility build on top of them (apt,
+aptitude, dnf/yum, zypper, ...). Be aware that the packages generated using
+these two make targets are designed to work on various distributions utilizing
+those formats, they thus will sometimes behave differently than your
+distribution's kernel packages.
+
+[:ref:`back to step-by-step guide <build_bissbs>`]
+
+.. _install_bisref:
+
+Put the kernel in place
+~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Install the kernel you just built.* [:ref:`... <install_bissbs>`]
+
+What you need to do after executing the command in the step-by-step guide
+depends on the existence and the implementation of ``/sbin/installkernel``
+executable on your distribution.
+
+If installkernel is found, the kernel's build system will delegate the actual
+installation of your kernel image to this executable, which then performs some
+or all of these tasks:
+
+* On almost all Linux distributions installkernel will store your kernel's
+ image in /boot/, usually as '/boot/vmlinuz-<kernelrelease_id>'; often it will
+ put a 'System.map-<kernelrelease_id>' alongside it.
+
+* On most distributions installkernel will then generate an 'initramfs'
+ (sometimes also called 'initrd'), which usually are stored as
+ '/boot/initramfs-<kernelrelease_id>.img' or
+ '/boot/initrd-<kernelrelease_id>'. Commodity distributions rely on this file
+ for booting, hence ensure to execute the make target 'modules_install' first,
+ as your distribution's initramfs generator otherwise will be unable to find
+ the modules that go into the image.
+
+* On some distributions installkernel will then add an entry for your kernel
+ to your bootloader's configuration.
+
+You have to take care of some or all of the tasks yourself, if your
+distribution lacks an installkernel script or does only handle part of them.
+Consult the distribution's documentation for details. If in doubt, install the
+kernel manually::
+
+ sudo install -m 0600 $(make -s image_name) /boot/vmlinuz-$(make -s kernelrelease)
+ sudo install -m 0600 System.map /boot/System.map-$(make -s kernelrelease)
+
+Now generate your initramfs using the tools your distribution provides for this
+process. Afterwards add your kernel to your bootloader configuration and reboot.
+
+[:ref:`back to step-by-step guide <install_bissbs>`]
+
+.. _storagespace_bisref:
+
+Storage requirements per kernel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Check how much storage space the kernel, its modules, and other related files
+ like the initramfs consume.* [:ref:`... <storagespace_bissbs>`]
+
+The kernels built during a bisection consume quite a bit of space in /boot/ and
+/lib/modules/, especially if you enabled debug symbols. That makes it easy to
+fill up volumes during a bisection -- and due to that even kernels which used to
+work earlier might fail to boot. To prevent that you will need to know how much
+space each installed kernel typically requires.
+
+Note, most of the time the pattern '/boot/*$(make -s kernelrelease)*' used in
+the guide will match all files needed to boot your kernel -- but neither the
+path nor the naming scheme are mandatory. On some distributions you thus will
+need to look in different places.

+
+Check if your newly built kernel considers itself 'tainted'
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Check if the kernel marked itself as 'tainted'.*
+ [:ref:`... <tainted_bissbs>`]
+
+Linux marks itself as tainted when something happens that potentially leads to
+follow-up errors that look totally unrelated. That is why developers might
+ignore or react scantly to reports from tainted kernels -- unless of course the
+kernel set the flag right when the reported bug occurred.
+
+That's why you want check why a kernel is tainted as explained in
+Documentation/admin-guide/tainted-kernels.rst; doing so is also in your own
+interest, as your testing might be flawed otherwise.

+
+Check the kernel built from a recent mainline codebase
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Verify if your bug occurs with the newly built kernel.*
+ [:ref:`... <recheckbroken_bissbs>`]
+
+There are a couple of reasons why your bug or regression might not show up with
+the kernel you built from the latest codebase. These are the most frequent:
+
+* The bug was fixed meanwhile.
+
+* What you suspected to be a regression was caused by a change in the build
+ configuration the provider of your kernel carried out.
+
+* Your problem might be a race condition that does not show up with your kernel;
+ the trimmed build configuration, a different setting for debug symbols, the
+ compiler used, and various other things can cause this.
+
+* In case you encountered the regression with a stable/longterm kernel it might
+ be a problem that is specific to that series; the next step in this guide will
+ check this.
+
+[:ref:`back to step-by-step guide <recheckbroken_bissbs>`]
+
+.. _recheckstablebroken_bisref:

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Are you facing a regression within a stable/longterm release, but failed to
+ reproduce it with the kernel you just built using the latest mainline sources?
+ Then check if the latest codebase for the particular series might already fix
+ the problem.* [:ref:`... <recheckstablebroken_bissbs>`]
+
+If this kernel does not show the regression either, there most likely is no need
+for a bisection.

+.. _introworkingcheck_bisref:
+
+Ensure the 'good' version is really working well
+------------------------------------------------
+
+ *Check if the kernels you build work fine.*
+ [:ref:`... <introworkingcheck_bissbs>`]
+
+This section will reestablish a known working base. Skipping it might be
+appealing, but is usually a bad idea, as it does something important:
+
+It will ensure the .config file you prepared earlier actually works as expected.
+That is in your own interest, as trimming the configuration is not foolproof --
+and you might be building and testing ten or more kernels for nothing before
+starting to suspect something might be wrong with the build configuration.
+
+That alone is reason enough to spend the time on this, but not the only reason.
+
+Many readers of this guide normally run kernels that are patched, use add-on
+modules, or both. Those kernels thus are not considered 'vanilla' -- therefore
+it's possible that the thing that regressed might never have worked in vanilla
+builds of the 'good' version in the first place.
+
+There is a third reason for those that noticed a regression between
+stable/longterm kernels of different series (e.g. 6.0.13..6.1.5): it will
+ensure the kernel version you assumed to be 'good' earlier in the process (e.g.
+6.0) actually is working.
+
+[:ref:`back to step-by-step guide <introworkingcheck_bissbs>`]
+
+.. _recheckworking_bisref:
+
+Build your own version of the 'good' kernel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Build your own variant of the working kernel and check if the feature that
+ regressed works as expected with it.* [:ref:`... <recheckworking_bissbs>`]
+
+In case the feature that broke with newer kernels does not work with your first
+self-built kernel, find and resolve the cause before moving on. There are a
+multitude of reasons why this might happen. Some ideas where to look:
+
+* Check the taint status and the output of ``dmesg``, maybe something unrelated
+ went wrong.
+
+* Maybe localmodconfig did something odd and disabled the module required to
+ test the feature? Then you might want to recreate a .config file based on the
+ one from the last working kernel and skip trimming it down; manually disabling
+ some features in the .config might work as well to reduce the build time.
+
+* Maybe it's not a kernel regression and something that is caused by some fluke,
+ a broken initramfs (also known as initrd), new firmware files, or an updated
+ userland software?
+
+* Maybe it was a feature added to your distributor's kernel which vanilla Linux
+ at that point never supported?
+
+Note, if you found and fixed problems with the .config file, you want to use it
+to build another kernel from the latest codebase, as your earlier tests with
+mainline and the latest version from an affected stable/longterm series were
+most likely flawed.

+
+This will start the bisection process; the last of the commands will make Git

+Build a kernel from the bisection point
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *Build, install, and boot a kernel from the code Git checked out using the

+
+There are two things worth of note here:
+
+* Occasionally building the kernel will fail or it might not boot due some
+ problem in the code at the bisection point. In that case run this command::
+
+ git bisect skip
+
+ Git will then check out another commit nearby which with a bit of luck should
+ work better. Afterwards restart executing this step.
+
+* Those slightly odd looking version identifiers can happen during bisections,
+ because the Linux kernel subsystems prepare their changes for a new mainline
+ release (say 6.2) before its predecessor (e.g. 6.1) is finished. They thus
+ base them on a somewhat earlier point like 6.1-rc1 or even 6.0 -- and then
+ get merged for 6.2 without rebasing nor squashing them once 6.1 is out. This
+ leads to those slightly odd looking version identifiers coming up during

+
+As indicated above: declaring just one kernel wrongly as 'good' or 'bad' will
+render the end result of a bisection useless. In that case you'd normally have
+to restart the bisection from scratch. The log can prevent that, as it might
+allow someone to point out where a bisection likely went sideways -- and then
+instead of testing ten or more kernels you might only have to build a few to
+resolve things.
+
+The .config file is put aside, as there is a decent chance that developers might

+
+This is an optional step, but whenever possible one you should try: there is a
+decent chance that developers will ask you to perform this step when you bring
+the bisection result up. So give it a try, you are in the flow already, building
+one more kernel shouldn't be a big deal at this point.
+
+The step-by-step guide covers everything relevant already except one slightly
+rare thing: did you bisected a regression that also happened with mainline using
+a stable/longterm series, but Git failed to revert the commit in mainline? Then
+try to revert the culprit in the affected stable/longterm series -- and if that
+succeeds, test that kernel version instead.

+
+Cleanup steps during and after following this guide
+---------------------------------------------------
+
+ *During and after following this guide you might want or need to remove some
+ of the kernels you installed.* [:ref:`... <introclosure_bissbs>`]
+
+The steps in this section describe clean-up procedures.
+
+[:ref:`back to step-by-step guide <introclosure_bissbs>`].
+
+.. _makeroom_bisref:
+
+Cleaning up during the bisection
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ *To remove one of the kernels you installed, look up its 'kernelrelease'
+ identifier.* [:ref:`... <makeroom_bissbs>`]
+
+The kernels you install during this process are easy to remove later, as its
+parts are only stored in two places and clearly identifiable. You thus do not
+need to worry to mess up your machine when you install a kernel manually (and
+thus bypass your distribution's packaging system): all parts of your kernels are
+relatively easy to remove later.
+
+One of the two places is a directory in /lib/modules/, which holds the modules
+for each installed kernel. This directory is named after the kernel's release
+identifier; hence, to remove all modules for one of the kernels you built,
+simply remove its modules directory in /lib/modules/.
+
+The other place is /boot/, where typically two up to five files will be placed
+during installation of a kernel. All of them usually contain the release name in
+their file name, but how many files and their exact names depend somewhat on
+your distribution's installkernel executable and its initramfs generator. On
+some distributions the ``kernel-install remove...`` command mentioned in the
+step-by-step guide will delete all of these files for you while also removing
+the menu entry for the kernel from your bootloader configuration. On others you
+have to take care of these two tasks yourself. The following command should
+interactively remove the three main files of a kernel with the release name
+'6.0-rc1-local-gcafec0cacaca0'::
+
+ rm -i /boot/{System.map,vmlinuz,initr}-6.0-rc1-local-gcafec0cacaca0
+
+Afterwards check for other files in /boot/ that have
+'6.0-rc1-local-gcafec0cacaca0' in their name and consider deleting them as well.
+Now remove the boot entry for the kernel from your bootloader's configuration;
+the steps to do that vary quite a bit between Linux distributions.
+
+Note, be careful with wildcards like '*' when deleting files or directories
+for kernels manually: you might accidentally remove files of a 6.0.13 kernel
+when all you want is to remove 6.0 or 6.0.1.

+
+ *Once you have finished the bisection, do not immediately remove anything
+ you set up, as you might need a few things again.*
+ [:ref:`... <finishingtouch_bissbs>`]
+
+When you are really short of storage space removing the kernels as described in
+the step-by-step guide might not free as much space as you would like. In that
+case consider running ``rm -rf ~/linux/*`` as well now. This will remove the
+build artifacts and the Linux sources, but will leave the Git repository
+(~/linux/.git/) behind -- a simple ``git reset --hard`` thus will bring the
+sources back.
+
+Removing the repository as well would likely be unwise at this point: there
+is a decent chance developers will ask you to build another kernel to
+perform additional tests -- like testing a debug patch or a proposed fix.
+Details on how to perform those can be found in the section :ref:`Optional
+tasks: test reverts, patches, or later versions <introoptional_bissbs>`.

+Additional information
+======================
+
+.. _buildhost_bis:
+
+Build kernels on a different machine
+------------------------------------
+
+To compile kernels on another system, slightly alter the step-by-step guide's
+instructions:
+
+* Start following the guide on the machine where you want to install and test
+ the kernels later.
+
+* After executing ':ref:`Boot into the working kernel and briefly use the
+ apparently broken feature <bootworking_bissbs>`', save the list of loaded
+ modules to a file using ``lsmod > ~/test-machine-lsmod``. Then locate the
+ build configuration for the running kernel (see ':ref:`Start defining the
+ build configuration for your kernel <oldconfig_bisref>`' for hints on where
+ to find it) and store it as '~/test-machine-config-working'. Transfer both
+ files to the home directory of your build host.
+
+* Continue the guide on the build host (e.g. with ':ref:`Ensure to have enough
+ free space for building [...] <diskspace_bissbs>`').
+
+* When you reach ':ref:`Start preparing a kernel build configuration[...]
+ <oldconfig_bissbs>`': before running ``make olddefconfig`` for the first time,
+ execute the following command to base your configuration on the one from the
+ test machine's 'working' kernel::
+
+ cp ~/test-machine-config-working ~/linux/.config
+
+* During the next step to ':ref:`disable any apparently superfluous kernel
+ modules <localmodconfig_bissbs>`' use the following command instead::
+
+ yes '' | make localmodconfig LSMOD=~/lsmod_foo-machine localmodconfig
+
+* Continue the guide, but ignore the instructions outlining how to compile,
+ install, and reboot into a kernel every time they come up. Instead build
+ like this::
+
+ cp ~/kernel-config-working .config
+ make olddefconfig &&
+ make -j $(nproc --all) targz-pkg
+
+ This will generate a gzipped tar file whose name is printed in the last
+ line shown; for example, a kernel with the kernelrelease identifier
+ '6.0.0-rc1-local-g928a87efa423' built for x86 machines usually will
+ be stored as '~/linux/linux-6.0.0-rc1-local-g928a87efa423-x86.tar.gz'.
+
+ Copy that file to your test machine's home directory.
+
+* Switch to the test machine to check if you have enough space to hold another
+ kernel. Then extract the file you transferred::
+
+ sudo tar -xvzf ~/linux-6.0.0-rc1-local-g928a87efa423-x86.tar.gz -C /
+
+ Afterwards :ref:`generate the initramfs and add the kernel to your boot
+ loader's configuration <install_bisref>`; on some distributions the following
+ command will take care of both these tasks::
+
+ sudo /sbin/installkernel 6.0.0-rc1-local-g928a87efa423 /boot/vmlinuz-6.0.0-rc1-local-g928a87efa423
+
+ Now reboot and ensure you started the intended kernel.
+
+This approach even works when building for another architecture: just install
+cross-compilers and add the appropriate parameters to every invocation of make
+(e.g. ``make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- [...]``).

+================================================
+The Unified Extensible Firmware Interface (UEFI)
+================================================
+
+UEFI, the Unified Extensible Firmware Interface, is a specification
+governing the behaviours of compatible firmware interfaces. It is
+maintained by the UEFI Forum - http://www.uefi.org/.
+
+UEFI is an evolution of its predecessor 'EFI', so the terms EFI and
+UEFI are used somewhat interchangeably in this document and associated
+source code. As a rule, anything new uses 'UEFI', whereas 'EFI' refers
+to legacy code or specifications.
+
+UEFI support in Linux
+=====================
+Booting on a platform with firmware compliant with the UEFI specification
+makes it possible for the kernel to support additional features:
+
+- UEFI Runtime Services
+- Retrieving various configuration information through the standardised
+ interface of UEFI configuration tables. (ACPI, SMBIOS, ...)
+
+For actually enabling [U]EFI support, enable:
+
+- CONFIG_EFI=y
+- CONFIG_EFIVAR_FS=y or m
+
+The implementation depends on receiving information about the UEFI environment
+in a Flattened Device Tree (FDT) - so is only available with CONFIG_OF.
+
+UEFI stub
+=========
+The "stub" is a feature that extends the Image/zImage into a valid UEFI
+PE/COFF executable, including a loader application that makes it possible to
+load the kernel directly from the UEFI shell, boot menu, or one of the
+lightweight bootloaders like Gummiboot or rEFInd.
+
+The kernel image built with stub support remains a valid kernel image for
+booting in non-UEFI environments.
+
+UEFI kernel support on ARM
+==========================
+UEFI kernel support on the ARM architectures (arm and arm64) is only available
+when boot is performed through the stub.
+
+When booting in UEFI mode, the stub deletes any memory nodes from a provided DT.
+Instead, the kernel reads the UEFI memory map.
+
+The stub populates the FDT /chosen node with (and the kernel scans for) the
+following parameters:
+

+=======================================================
+Activity Monitors Unit (AMU) extension in AArch64 Linux
+=======================================================
+
+Author: Ionela Voinescu <ionela.voinescu@arm.com>
+
+Date: 2019-09-10
+
+This document briefly describes the provision of Activity Monitors Unit
+support in AArch64 Linux.
+
+
+Architecture overview
+---------------------
+
+The activity monitors extension is an optional extension introduced by the
+ARMv8.4 CPU architecture.
+
+The activity monitors unit, implemented in each CPU, provides performance
+counters intended for system management use. The AMU extension provides a
+system register interface to the counter registers and also supports an
+optional external memory-mapped interface.
+
+Version 1 of the Activity Monitors architecture implements a counter group
+of four fixed and architecturally defined 64-bit event counters.
+
+ - CPU cycle counter: increments at the frequency of the CPU.
+ - Constant counter: increments at the fixed frequency of the system
+ clock.
+ - Instructions retired: increments with every architecturally executed
+ instruction.
+ - Memory stall cycles: counts instruction dispatch stall cycles caused by
+ misses in the last level cache within the clock domain.
+
+When in WFI or WFE these counters do not increment.
+
+The Activity Monitors architecture provides space for up to 16 architected
+event counters. Future versions of the architecture may use this space to
+implement additional architected event counters.
+
+Additionally, version 1 implements a counter group of up to 16 auxiliary
+64-bit event counters.
+
+On cold reset all counters reset to 0.
+
+
+Basic support
+-------------
+
+The kernel can safely run a mix of CPUs with and without support for the
+activity monitors extension. Therefore, when CONFIG_ARM64_AMU_EXTN is
+selected we unconditionally enable the capability to allow any late CPU
+(secondary or hotplugged) to detect and use the feature.
+
+When the feature is detected on a CPU, we flag the availability of the
+feature but this does not guarantee the correct functionality of the
+counters, only the presence of the extension.
+
+Firmware (code running at higher exception levels, e.g. arm-tf) support is
+needed to:
+
+ - Enable access for lower exception levels (EL2 and EL1) to the AMU
+ registers.
+ - Enable the counters. If not enabled these will read as 0.
+ - Save/restore the counters before/after the CPU is being put/brought up
+ from the 'off' power state.
+
+When using kernels that have this feature enabled but boot with broken
+firmware the user may experience panics or lockups when accessing the
+counter registers. Even if these symptoms are not observed, the values
+returned by the register reads might not correctly reflect reality. Most
+commonly, the counters will read as 0, indicating that they are not
+enabled.
+
+If proper support is not provided in firmware it's best to disable
+CONFIG_ARM64_AMU_EXTN. To be noted that for security reasons, this does not
+bypass the setting of AMUSERENR_EL0 to trap accesses from EL0 (userspace) to
+EL1 (kernel). Therefore, firmware should still ensure accesses to AMU registers
+are not trapped in EL2/EL3.
+
+The fixed counters of AMUv1 are accessible through the following system
+register definitions:
+
+ - SYS_AMEVCNTR0_CORE_EL0
+ - SYS_AMEVCNTR0_CONST_EL0
+ - SYS_AMEVCNTR0_INST_RET_EL0
+ - SYS_AMEVCNTR0_MEM_STALL_EL0
+
+Auxiliary platform specific counters can be accessed using
+SYS_AMEVCNTR1_EL0(n), where n is a value between 0 and 15.
+
+Details can be found in: arch/arm64/include/asm/sysreg.h.
+
+
+Userspace access
+----------------
+
+Currently, access from userspace to the AMU registers is disabled due to:
+
+ - Security reasons: they might expose information about code executed in
+ secure mode.
+ - Purpose: AMU counters are intended for system management use.
+
+Also, the presence of the feature is not visible to userspace.
+
+
+Virtualization
+--------------
+
+Currently, access from userspace (EL0) and kernelspace (EL1) on the KVM
+guest side is disabled due to:
+
+ - Security reasons: they might expose information about code executed
+ by other guests or the host.
+
+Any attempt to access the AMU registers will result in an UNDEFINED
+exception being injected into the guest.

+Arm Confidential Compute Architecture
+=====================================
+
+Arm systems that support the Realm Management Extension (RME) contain
+hardware to allow a VM guest to be run in a way which protects the code
+and data of the guest from the hypervisor. It extends the older "two
+world" model (Normal and Secure World) into four worlds: Normal, Secure,
+Root and Realm. Linux can then also be run as a guest to a monitor
+running in the Realm world.
+
+The monitor running in the Realm world is known as the Realm Management
+Monitor (RMM) and implements the Realm Management Monitor
+specification[1]. The monitor acts a bit like a hypervisor (e.g. it runs
+in EL2 and manages the stage 2 page tables etc of the guests running in
+Realm world), however much of the control is handled by a hypervisor
+running in the Normal World. The Normal World hypervisor uses the Realm
+Management Interface (RMI) defined by the RMM specification to request
+the RMM to perform operations (e.g. mapping memory or executing a vCPU).
+
+The RMM defines an environment for guests where the address space (IPA)
+is split into two. The lower half is protected - any memory that is
+mapped in this half cannot be seen by the Normal World and the RMM
+restricts what operations the Normal World can perform on this memory
+(e.g. the Normal World cannot replace pages in this region without the
+guest's cooperation). The upper half is shared, the Normal World is free
+to make changes to the pages in this region, and is able to emulate MMIO
+devices in this region too.
+
+A guest running in a Realm may also communicate with the RMM using the
+Realm Services Interface (RSI) to request changes in its environment or
+to perform attestation about its environment. In particular it may
+request that areas of the protected address space are transitioned
+between 'RAM' and 'EMPTY' (in either direction). This allows a Realm
+guest to give up memory to be returned to the Normal World, or to
+request new memory from the Normal World. Without an explicit request
+from the Realm guest the RMM will otherwise prevent the Normal World
+from making these changes.
+
+Linux as a Realm Guest
+----------------------
+
+To run Linux as a guest within a Realm, the following must be provided
+either by the VMM or by a `boot loader` run in the Realm before Linux:
+
+ * All protected RAM described to Linux (by DT or ACPI) must be marked
+ RIPAS RAM before handing control over to Linux.
+
+ * MMIO devices must be either unprotected (e.g. emulated by the Normal
+ World) or marked RIPAS DEV.
+
+ * MMIO devices emulated by the Normal World and used very early in boot
+ (specifically earlycon) must be specified in the upper half of IPA.
+ For earlycon this can be done by specifying the address on the
+ command line, e.g. with an IPA size of 33 bits and the base address
+ of the emulated UART at 0x1000000: ``earlycon=uart,mmio,0x101000000``
+
+ * Linux will use bounce buffers for communicating with unprotected
+ devices. It will transition some protected memory to RIPAS EMPTY and
+ expect to be able to access unprotected pages at the same IPA address
+ but with the highest valid IPA bit set. The expectation is that the
+ VMM will remove the physical pages from the protected mapping and
+ provide those pages as unprotected pages.

+=====================
+Booting AArch64 Linux
+=====================
+
+Author: Will Deacon <will.deacon@arm.com>
+
+Date : 07 September 2012
+
+This document is based on the ARM booting document by Russell King and
+is relevant to all public releases of the AArch64 Linux kernel.
+
+The AArch64 exception model is made up of a number of exception levels
+(EL0 - EL3), with EL0, EL1 and EL2 having a secure and a non-secure
+counterpart. EL2 is the hypervisor level, EL3 is the highest priority
+level and exists only in secure mode. Both are architecturally optional.
+
+For the purposes of this document, we will use the term `boot loader`
+simply to define all software that executes on the CPU(s) before control
+is passed to the Linux kernel. This may include secure monitor and
+hypervisor code, or it may just be a handful of instructions for
+preparing a minimal boot environment.
+
+Essentially, the boot loader should provide (as a minimum) the
+following:
+
+1. Setup and initialise the RAM
+2. Setup the device tree
+3. Decompress the kernel image
+4. Call the kernel image
+
+
+1. Setup and initialise RAM
+---------------------------
+
+Requirement: MANDATORY
+
+The boot loader is expected to find and initialise all RAM that the
+kernel will use for volatile data storage in the system. It performs
+this in a machine dependent manner. (It may use internal algorithms
+to automatically locate and size all RAM, or it may use knowledge of
+the RAM in the machine, or any other method the boot loader designer
+sees fit.)
+
+For Arm Confidential Compute Realms this includes ensuring that all
+protected RAM has a Realm IPA state (RIPAS) of "RAM".
+
+
+2. Setup the device tree
+-------------------------
+
+Requirement: MANDATORY
+
+The device tree blob (dtb) must be placed on an 8-byte boundary and must
+not exceed 2 megabytes in size. Since the dtb will be mapped cacheable
+using blocks of up to 2 megabytes in size, it must not be placed within
+any 2M region which must be mapped with any specific attributes.
+
+NOTE: versions prior to v4.2 also require that the DTB be placed within
+the 512 MB region starting at text_offset bytes below the kernel Image.
+
+3. Decompress the kernel image
+------------------------------
+
+Requirement: OPTIONAL
+
+The AArch64 kernel does not currently provide a decompressor and
+therefore requires decompression (gzip etc.) to be performed by the boot
+loader if a compressed Image target (e.g. Image.gz) is used. For
+bootloaders that do not implement this requirement, the uncompressed
+Image target is available instead.
+
+
+4. Call the kernel image
+------------------------
+
+Requirement: MANDATORY
+
+The decompressed kernel image contains a 64-byte header as follows::
+
+ u32 code0; /* Executable code */
+ u32 code1; /* Executable code */
+ u64 text_offset; /* Image load offset, little endian */
+ u64 image_size; /* Effective Image size, little endian */
+ u64 flags; /* kernel flags, little endian */
+ u64 res2 = 0; /* reserved */
+ u64 res3 = 0; /* reserved */
+ u64 res4 = 0; /* reserved */
+ u32 magic = 0x644d5241; /* Magic number, little endian, "ARM\x64" */
+ u32 res5; /* reserved (used for PE COFF offset) */
+
+
+Header notes:
+
+- As of v3.17, all fields are little endian unless stated otherwise.
+
+- code0/code1 are responsible for branching to stext.
+
+- when booting through EFI, code0/code1 are initially skipped.
+ res5 is an offset to the PE header and the PE header has the EFI
+ entry point (efi_stub_entry). When the stub has done its work, it
+ jumps to code0 to resume the normal boot process.
+
+- Prior to v3.17, the endianness of text_offset was not specified. In
+ these cases image_size is zero and text_offset is 0x80000 in the
+ endianness of the kernel. Where image_size is non-zero image_size is
+ little-endian and must be respected. Where image_size is zero,
+ text_offset can be assumed to be 0x80000.
+
+- The flags field (introduced in v3.17) is a little-endian 64-bit field
+ composed as follows:
+
+ ============= ===============================================================
+ Bit 0 Kernel endianness. 1 if BE, 0 if LE.
+ Bit 1-2 Kernel Page size.
+
+ * 0 - Unspecified.
+ * 1 - 4K
+ * 2 - 16K
+ * 3 - 64K
+ Bit 3 Kernel physical placement
+
+ 0
+ 2MB aligned base should be as close as possible
+ to the base of DRAM, since memory below it is not
+ accessible via the linear mapping
+ 1
+ 2MB aligned base such that all image_size bytes
+ counted from the start of the image are within
+ the 48-bit addressable range of physical memory
+ Bits 4-63 Reserved.
+ ============= ===============================================================
+
+- When image_size is zero, a bootloader should attempt to keep as much
+ memory as possible free for use by the kernel immediately after the
+ end of the kernel image. The amount of space required will vary
+ depending on selected features, and is effectively unbound.
+
+The Image must be placed text_offset bytes from a 2MB aligned base
+address anywhere in usable system RAM and called there. The region
+between the 2 MB aligned base address and the start of the image has no
+special significance to the kernel, and may be used for other purposes.
+At least image_size bytes from the start of the image must be free for
+use by the kernel.
+NOTE: versions prior to v4.6 cannot make use of memory below the
+physical offset of the Image so it is recommended that the Image be
+placed as close as possible to the start of system RAM.
+
+If an initrd/initramfs is passed to the kernel at boot, it must reside
+entirely within a 1 GB aligned physical memory window of up to 32 GB in
+size that fully covers the kernel Image as well.
+
+Any memory described to the kernel (even that below the start of the
+image) which is not marked as reserved from the kernel (e.g., with a
+memreserve region in the device tree) will be considered as available to
+the kernel.
+
+Before jumping into the kernel, the following conditions must be met:
+
+- Quiesce all DMA capable devices so that memory does not get
+ corrupted by bogus network packets or disk data. This will save
+ you many hours of debug.
+
+- Primary CPU general-purpose register settings:
+
+ - x0 = physical address of device tree blob (dtb) in system RAM.
+ - x1 = 0 (reserved for future use)
+ - x2 = 0 (reserved for future use)
+ - x3 = 0 (reserved for future use)
+
+- CPU mode
+
+ All forms of interrupts must be masked in PSTATE.DAIF (Debug, SError,
+ IRQ and FIQ).
+ The CPU must be in non-secure state, either in EL2 (RECOMMENDED in order
+ to have access to the virtualisation extensions), or in EL1.
+
+- Caches, MMUs
+
+ The MMU must be off.
+
+ The instruction cache may be on or off, and must not hold any stale
+ entries corresponding to the loaded kernel image.
+
+ The address range corresponding to the loaded kernel image must be
+ cleaned to the PoC. In the presence of a system cache or other
+ coherent masters with caches enabled, this will typically require
+ cache maintenance by VA rather than set/way operations.
+ System caches which respect the architected cache maintenance by VA
+ operations must be configured and may be enabled.
+ System caches which do not respect architected cache maintenance by VA
+ operations (not recommended) must be configured and disabled.
+
+- Architected timers
+
+ CNTFRQ must be programmed with the timer frequency and CNTVOFF must
+ be programmed with a consistent value on all CPUs. If entering the
+ kernel at EL1, CNTHCTL_EL2 must have EL1PCTEN (bit 0) set where
+ available.
+
+- Coherency
+
+ All CPUs to be booted by the kernel must be part of the same coherency
+ domain on entry to the kernel. This may require IMPLEMENTATION DEFINED
+ initialisation to enable the receiving of maintenance operations on
+ each CPU.
+
+- System registers
+
+ All writable architected system registers at or below the exception
+ level where the kernel image will be entered must be initialised by
+ software at a higher exception level to prevent execution in an UNKNOWN
+ state.
+
+ For all systems:
+ - If EL3 is present:

+
+The requirements described above for CPU mode, caches, MMUs, architected
+timers, coherency and system registers apply to all CPUs. All CPUs must
+enter the kernel in the same exception level. Where the values documented
+disable traps it is permissible for these traps to be enabled so long as
+those traps are handled transparently by higher exception levels as though
+the values documented were set.
+
+The boot loader is expected to enter the kernel on each CPU in the
+following manner:
+
+- The primary CPU must jump directly to the first instruction of the
+ kernel image. The device tree blob passed by this CPU must contain
+ an 'enable-method' property for each cpu node. The supported
+ enable-methods are described below.
+
+ It is expected that the bootloader will generate these device tree
+ properties and insert them into the blob prior to kernel entry.
+
+- CPUs with a "spin-table" enable-method must have a 'cpu-release-addr'
+ property in their cpu node. This property identifies a
+ naturally-aligned 64-bit zero-initalised memory location.
+
+ These CPUs should spin outside of the kernel in a reserved area of
+ memory (communicated to the kernel by a /memreserve/ region in the
+ device tree) polling their cpu-release-addr location, which must be
+ contained in the reserved region. A wfe instruction may be inserted
+ to reduce the overhead of the busy-loop and a sev will be issued by
+ the primary CPU. When a read of the location pointed to by the
+ cpu-release-addr returns a non-zero value, the CPU must jump to this
+ value. The value will be written as a single 64-bit little-endian
+ value, so CPUs must convert the read value to their native endianness
+ before jumping to it.
+
+- CPUs with a "psci" enable method should remain outside of
+ the kernel (i.e. outside of the regions of memory described to the
+ kernel in the memory node, or in a reserved area of memory described
+ to the kernel by a /memreserve/ region in the device tree). The
+ kernel will issue CPU_ON calls as described in ARM document number ARM
+ DEN 0022A ("Power State Coordination Interface System Software on ARM
+ processors") to bring CPUs into the kernel.
+
+ The device tree should contain a 'psci' node, as described in
+ Documentation/devicetree/bindings/arm/psci.yaml.

+====================
+CPU Hotplug and ACPI
+====================
+
+CPU hotplug in the arm64 world is commonly used to describe the kernel taking
+CPUs online/offline using PSCI. This document is about ACPI firmware allowing
+CPUs that were not available during boot to be added to the system later.
+
+``possible`` and ``present`` refer to the state of the CPU as seen by linux.
+
+
+CPU Hotplug on physical systems - CPUs not present at boot
+----------------------------------------------------------
+
+Physical systems need to mark a CPU that is ``possible`` but not ``present`` as
+being ``present``. An example would be a dual socket machine, where the package
+in one of the sockets can be replaced while the system is running.
+
+This is not supported.
+
+In the arm64 world CPUs are not a single device but a slice of the system.
+There are no systems that support the physical addition (or removal) of CPUs
+while the system is running, and ACPI is not able to sufficiently describe
+them.
+
+e.g. New CPUs come with new caches, but the platform's cache topology is
+described in a static table, the PPTT. How caches are shared between CPUs is
+not discoverable, and must be described by firmware.
+
+e.g. The GIC redistributor for each CPU must be accessed by the driver during
+boot to discover the system wide supported features. ACPI's MADT GICC
+structures can describe a redistributor associated with a disabled CPU, but
+can't describe whether the redistributor is accessible, only that it is not
+'always on'.
+
+arm64's ACPI tables assume that everything described is ``present``.
+
+
+CPU Hotplug on virtual systems - CPUs not enabled at boot
+---------------------------------------------------------
+
+Virtual systems have the advantage that all the properties the system will
+ever have can be described at boot. There are no power-domain considerations
+as such devices are emulated.
+
+CPU Hotplug on virtual systems is supported. It is distinct from physical
+CPU Hotplug as all resources are described as ``present``, but CPUs may be
+marked as disabled by firmware. Only the CPU's online/offline behaviour is
+influenced by firmware. An example is where a virtual machine boots with a
+single CPU, and additional CPUs are added once a cloud orchestrator deploys
+the workload.
+
+For a virtual machine, the VMM (e.g. Qemu) plays the part of firmware.
+
+Virtual hotplug is implemented as a firmware policy affecting which CPUs can be
+brought online. Firmware can enforce its policy via PSCI's return codes. e.g.
+``DENIED``.
+
+The ACPI tables must describe all the resources of the virtual machine. CPUs
+that firmware wishes to disable either from boot (or later) should not be
+``enabled`` in the MADT GICC structures, but should have the ``online capable``
+bit set, to indicate they can be enabled later. The boot CPU must be marked as
+``enabled``. The 'always on' GICR structure must be used to describe the
+redistributors.
+
+CPUs described as ``online capable`` but not ``enabled`` can be set to enabled
+by the DSDT's Processor object's _STA method. On virtual systems the _STA method
+must always report the CPU as ``present``. Changes to the firmware policy can
+be notified to the OS via device-check or eject-request.
+
+CPUs described as ``enabled`` in the static table, should not have their _STA
+modified dynamically by firmware. Soft-restart features such as kexec will
+re-read the static properties of the system from these static tables, and
+may malfunction if these no longer describe the running system. Linux will
+re-discover the dynamic properties of the system from the _STA method later
+during boot.

+
+================
+ARM64 ELF hwcaps
+================
+
+This document describes the usage and semantics of the arm64 ELF hwcaps.
+
+
+1. Introduction
+---------------
+
+Some hardware or software features are only available on some CPU
+implementations, and/or with certain kernel configurations, but have no
+architected discovery mechanism available to userspace code at EL0. The
+kernel exposes the presence of these features to userspace through a set
+of flags called hwcaps, exposed in the auxiliary vector.
+
+Userspace software can test for features by acquiring the AT_HWCAP,
+AT_HWCAP2 or AT_HWCAP3 entry of the auxiliary vector, and testing
+whether the relevant flags are set, e.g.::
+
+ bool floating_point_is_present(void)
+ {
+ unsigned long hwcaps = getauxval(AT_HWCAP);
+ if (hwcaps & HWCAP_FP)
+ return true;
+
+ return false;
+ }
+
+Where software relies on a feature described by a hwcap, it should check
+the relevant hwcap flag to verify that the feature is present before
+attempting to make use of the feature.
+
+Features cannot be probed reliably through other means. When a feature
+is not available, attempting to use it may result in unpredictable
+behaviour, and is not guaranteed to result in any reliable indication
+that the feature is unavailable, such as a SIGILL.
+
+
+2. Interpretation of hwcaps
+---------------------------
+
+The majority of hwcaps are intended to indicate the presence of features
+which are described by architected ID registers inaccessible to
+userspace code at EL0. These hwcaps are defined in terms of ID register
+fields, and should be interpreted with reference to the definition of
+these fields in the ARM Architecture Reference Manual (ARM ARM).
+
+Such hwcaps are described below in the form::
+
+ Functionality implied by idreg.field == val.
+
+Such hwcaps indicate the availability of functionality that the ARM ARM
+defines as being present when idreg.field has value val, but do not
+indicate that idreg.field is precisely equal to val, nor do they
+indicate the absence of functionality implied by other values of
+idreg.field.
+
+Other hwcaps may indicate the presence of features which cannot be
+described by ID registers alone. These may be described without
+reference to ID registers, and may refer to other documentation.
+

+===============================================
+Guarded Control Stack support for AArch64 Linux
+===============================================
+
+This document outlines briefly the interface provided to userspace by Linux in
+order to support use of the ARM Guarded Control Stack (GCS) feature.
+
+This is an outline of the most important features and issues only and not
+intended to be exhaustive.
+
+
+
+1. General
+-----------
+
+* GCS is an architecture feature intended to provide greater protection
+ against return oriented programming (ROP) attacks and to simplify the
+ implementation of features that need to collect stack traces such as
+ profiling.
+
+* When GCS is enabled a separate guarded control stack is maintained by the
+ PE which is writeable only through specific GCS operations. This
+ stores the call stack only, when a procedure call instruction is
+ performed the current PC is pushed onto the GCS and on RET the
+ address in the LR is verified against that on the top of the GCS.
+
+* When active the current GCS pointer is stored in the system register
+ GCSPR_EL0. This is readable by userspace but can only be updated
+ via specific GCS instructions.
+
+* The architecture provides instructions for switching between guarded
+ control stacks with checks to ensure that the new stack is a valid
+ target for switching.
+
+* The functionality of GCS is similar to that provided by the x86 Shadow
+ Stack feature, due to sharing of userspace interfaces the ABI refers to
+ shadow stacks rather than GCS.
+
+* Support for GCS is reported to userspace via HWCAP_GCS in the aux vector
+ AT_HWCAP entry.
+
+* GCS is enabled per thread. While there is support for disabling GCS
+ at runtime this should be done with great care.
+
+* GCS memory access faults are reported as normal memory access faults.
+
+* GCS specific errors (those reported with EC 0x2d) will be reported as
+ SIGSEGV with a si_code of SEGV_CPERR (control protection error).
+
+* GCS is supported only for AArch64.
+
+* On systems where GCS is supported GCSPR_EL0 is always readable by EL0
+ regardless of the GCS configuration for the thread.
+
+* The architecture supports enabling GCS without verifying that return values
+ in LR match those in the GCS, the LR will be ignored. This is not supported
+ by Linux.
+
+
+
+2. Enabling and disabling Guarded Control Stacks
+-------------------------------------------------
+
+* GCS is enabled and disabled for a thread via the PR_SET_SHADOW_STACK_STATUS
+ prctl(), this takes a single flags argument specifying which GCS features
+ should be used.
+
+* When set PR_SHADOW_STACK_ENABLE flag allocates a Guarded Control Stack
+ and enables GCS for the thread, enabling the functionality controlled by
+ GCSCRE0_EL1.{nTR, RVCHKEN, PCRSEL}.
+
+* When set the PR_SHADOW_STACK_PUSH flag enables the functionality controlled
+ by GCSCRE0_EL1.PUSHMEn, allowing explicit GCS pushes.
+
+* When set the PR_SHADOW_STACK_WRITE flag enables the functionality controlled
+ by GCSCRE0_EL1.STREn, allowing explicit stores to the Guarded Control Stack.
+
+* Any unknown flags will cause PR_SET_SHADOW_STACK_STATUS to return -EINVAL.
+
+* PR_LOCK_SHADOW_STACK_STATUS is passed a bitmask of features with the same
+ values as used for PR_SET_SHADOW_STACK_STATUS. Any future changes to the
+ status of the specified GCS mode bits will be rejected.
+
+* PR_LOCK_SHADOW_STACK_STATUS allows any bit to be locked, this allows
+ userspace to prevent changes to any future features.
+
+* There is no support for a process to remove a lock that has been set for
+ it.
+
+* PR_SET_SHADOW_STACK_STATUS and PR_LOCK_SHADOW_STACK_STATUS affect only the
+ thread that called them, any other running threads will be unaffected.
+
+* New threads inherit the GCS configuration of the thread that created them.
+
+* GCS is disabled on exec().
+
+* The current GCS configuration for a thread may be read with the
+ PR_GET_SHADOW_STACK_STATUS prctl(), this returns the same flags that
+ are passed to PR_SET_SHADOW_STACK_STATUS.
+
+* If GCS is disabled for a thread after having previously been enabled then
+ the stack will remain allocated for the lifetime of the thread. At present
+ any attempt to reenable GCS for the thread will be rejected, this may be
+ revisited in future.
+
+* It should be noted that since enabling GCS will result in GCS becoming
+ active immediately it is not normally possible to return from the function
+ that invoked the prctl() that enabled GCS. It is expected that the normal
+ usage will be that GCS is enabled very early in execution of a program.
+
+
+
+3. Allocation of Guarded Control Stacks
+----------------------------------------
+
+* When GCS is enabled for a thread a new Guarded Control Stack will be
+ allocated for it of half the standard stack size or 2 gigabytes,
+ whichever is smaller.
+
+* When a new thread is created by a thread which has GCS enabled then a
+ new Guarded Control Stack will be allocated for the new thread with
+ half the size of the standard stack.
+
+* When a stack is allocated by enabling GCS or during thread creation then
+ the top 8 bytes of the stack will be initialised to 0 and GCSPR_EL0 will
+ be set to point to the address of this 0 value, this can be used to
+ detect the top of the stack.
+
+* Additional Guarded Control Stacks can be allocated using the
+ map_shadow_stack() system call.
+
+* Stacks allocated using map_shadow_stack() can optionally have an end of
+ stack marker and cap placed at the top of the stack. If the flag
+ SHADOW_STACK_SET_TOKEN is specified a cap will be placed on the stack,
+ if SHADOW_STACK_SET_MARKER is not specified the cap will be the top 8
+ bytes of the stack and if it is specified then the cap will be the next
+ 8 bytes. While specifying just SHADOW_STACK_SET_MARKER by itself is
+ valid since the marker is all bits 0 it has no observable effect.
+
+* Stacks allocated using map_shadow_stack() must have a size which is a
+ multiple of 8 bytes larger than 8 bytes and must be 8 bytes aligned.
+
+* An address can be specified to map_shadow_stack(), if one is provided then
+ it must be aligned to a page boundary.
+
+* When a thread is freed the Guarded Control Stack initially allocated for
+ that thread will be freed. Note carefully that if the stack has been
+ switched this may not be the stack currently in use by the thread.
+
+
+4. Signal handling
+--------------------
+
+* A new signal frame record gcs_context encodes the current GCS mode and
+ pointer for the interrupted context on signal delivery. This will always
+ be present on systems that support GCS.
+
+* The record contains a flag field which reports the current GCS configuration
+ for the interrupted context as PR_GET_SHADOW_STACK_STATUS would.
+
+* The signal handler is run with the same GCS configuration as the interrupted
+ context.
+
+* When GCS is enabled for the interrupted thread a signal handling specific
+ GCS cap token will be written to the GCS, this is an architectural GCS cap
+ with the token type (bits 0..11) all clear. The GCSPR_EL0 reported in the
+ signal frame will point to this cap token.
+
+* The signal handler will use the same GCS as the interrupted context.
+
+* When GCS is enabled on signal entry a frame with the address of the signal
+ return handler will be pushed onto the GCS, allowing return from the signal
+ handler via RET as normal. This will not be reported in the gcs_context in
+ the signal frame.
+
+
+5. Signal return
+-----------------
+
+When returning from a signal handler:
+
+* If there is a gcs_context record in the signal frame then the GCS flags
+ and GCSPR_EL0 will be restored from that context prior to further
+ validation.
+
+* If there is no gcs_context record in the signal frame then the GCS
+ configuration will be unchanged.
+
+* If GCS is enabled on return from a signal handler then GCSPR_EL0 must
+ point to a valid GCS signal cap record, this will be popped from the
+ GCS prior to signal return.
+
+* If the GCS configuration is locked when returning from a signal then any
+ attempt to change the GCS configuration will be treated as an error. This
+ is true even if GCS was not enabled prior to signal entry.
+
+* GCS may be disabled via signal return but any attempt to enable GCS via
+ signal return will be rejected.
+
+
+6. ptrace extensions
+---------------------
+
+* A new regset NT_ARM_GCS is defined for use with PTRACE_GETREGSET and
+ PTRACE_SETREGSET.
+
+* The GCS mode, including enable and disable, may be configured via ptrace.
+ If GCS is enabled via ptrace no new GCS will be allocated for the thread.
+
+* Configuration via ptrace ignores locking of GCS mode bits.
+
+
+7. ELF coredump extensions
+---------------------------
+
+* NT_ARM_GCS notes will be added to each coredump for each thread of the
+ dumped process. The contents will be equivalent to the data that would
+ have been read if a PTRACE_GETREGSET of the corresponding type were
+ executed for each thread when the coredump was generated.
+
+
+
+8. /proc extensions
+--------------------
+
+* Guarded Control Stack pages will include "ss" in their VmFlags in
+ /proc/<pid>/smaps.

+=======================================
+crashkernel memory reservation on arm64
+=======================================
+
+Author: Baoquan He <bhe@redhat.com>
+
+Kdump mechanism is used to capture a corrupted kernel vmcore so that
+it can be subsequently analyzed. In order to do this, a preliminarily
+reserved memory is needed to pre-load the kdump kernel and boot such
+kernel if corruption happens.
+
+That reserved memory for kdump is adapted to be able to minimally
+accommodate the kdump kernel and the user space programs needed for the
+vmcore collection.
+
+Kernel parameter
+================
+
+Through the kernel parameters below, memory can be reserved accordingly
+during the early stage of the first kernel booting so that a continuous
+large chunk of memomy can be found. The low memory reservation needs to
+be considered if the crashkernel is reserved from the high memory area.
+
+- crashkernel=size@offset
+- crashkernel=size
+- crashkernel=size,high crashkernel=size,low
+
+Low memory and high memory
+==========================
+
+For kdump reservations, low memory is the memory area under a specific
+limit, usually decided by the accessible address bits of the DMA-capable
+devices needed by the kdump kernel to run. Those devices not related to
+vmcore dumping can be ignored. On arm64, the low memory upper bound is
+not fixed: it is 1G on the RPi4 platform but 4G on most other systems.
+On special kernels built with CONFIG_ZONE_(DMA|DMA32) disabled, the
+whole system RAM is low memory. Outside of the low memory described
+above, the rest of system RAM is considered high memory.
+
+Implementation
+==============
+
+1) crashkernel=size@offset
+--------------------------
+
+The crashkernel memory must be reserved at the user-specified region or
+fail if already occupied.
+
+
+2) crashkernel=size
+-------------------
+
+The crashkernel memory region will be reserved in any available position
+according to the search order:
+
+Firstly, the kernel searches the low memory area for an available region
+with the specified size.
+
+If searching for low memory fails, the kernel falls back to searching
+the high memory area for an available region of the specified size. If
+the reservation in high memory succeeds, a default size reservation in
+the low memory will be done. Currently the default size is 128M,
+sufficient for the low memory needs of the kdump kernel.
+
+Note: crashkernel=size is the recommended option for crashkernel kernel
+reservations. The user would not need to know the system memory layout
+for a specific platform.
+
+3) crashkernel=size,high crashkernel=size,low
+---------------------------------------------
+
+crashkernel=size,(high|low) are an important supplement to
+crashkernel=size. They allows the user to specify how much memory needs
+to be allocated from the high memory and low memory respectively. On
+many systems the low memory is precious and crashkernel reservations
+from this area should be kept to a minimum.
+
+To reserve memory for crashkernel=size,high, searching is first
+attempted from the high memory region. If the reservation succeeds, the
+low memory reservation will be done subsequently.
+
+If reservation from the high memory failed, the kernel falls back to
+searching the low memory with the specified size in crashkernel=,high.
+If it succeeds, no further reservation for low memory is needed.
+
+Notes:
+
+- If crashkernel=,low is not specified, the default low memory
+ reservation will be done automatically.
+
+- if crashkernel=0,low is specified, it means that the low memory
+ reservation is omitted intentionally.

+==============================
+Memory Layout on AArch64 Linux
+==============================
+
+Author: Catalin Marinas <catalin.marinas@arm.com>
+
+This document describes the virtual memory layout used by the AArch64
+Linux kernel. The architecture allows up to 4 levels of translation
+tables with a 4KB page size and up to 3 levels with a 64KB page size.
+
+AArch64 Linux uses either 3 levels or 4 levels of translation tables
+with the 4KB page configuration, allowing 39-bit (512GB) or 48-bit
+(256TB) virtual addresses, respectively, for both user and kernel. With
+64KB pages, only 2 levels of translation tables, allowing 42-bit (4TB)
+virtual address, are used but the memory layout is the same.
+
+ARMv8.2 adds optional support for Large Virtual Address space. This is
+only available when running with a 64KB page size and expands the
+number of descriptors in the first level of translation.
+
+TTBRx selection is given by bit 55 of the virtual address. The
+swapper_pg_dir contains only kernel (global) mappings while the user pgd
+contains only user (non-global) mappings. The swapper_pg_dir address is
+written to TTBR1 and never written to TTBR0.
+
+When using KVM without the Virtualization Host Extensions, the
+hypervisor maps kernel pages in EL2 at a fixed (and potentially
+random) offset from the linear mapping. See the kern_hyp_va macro and
+kvm_update_va_mask function for more details. MMIO devices such as
+GICv2 gets mapped next to the HYP idmap page, as do vectors when
+ARM64_SPECTRE_V3A is enabled for particular CPUs.
+
+When using KVM with the Virtualization Host Extensions, no additional
+mappings are created, since the host kernel runs directly in EL2.
+
+52-bit VA support in the kernel
+-------------------------------
+If the ARMv8.2-LVA optional feature is present, and we are running
+with a 64KB page size; then it is possible to use 52-bits of address
+space for both userspace and kernel addresses. However, any kernel
+binary that supports 52-bit must also be able to fall back to 48-bit
+at early boot time if the hardware feature is not present.
+
+This fallback mechanism necessitates the kernel .text to be in the
+higher addresses such that they are invariant to 48/52-bit VAs. Due
+to the kasan shadow being a fraction of the entire kernel VA space,
+the end of the kasan shadow must also be in the higher half of the
+kernel VA space for both 48/52-bit. (Switching from 48-bit to 52-bit,
+the end of the kasan shadow is invariant and dependent on ~0UL,
+whilst the start address will "grow" towards the lower addresses).
+
+In order to optimise phys_to_virt and virt_to_phys, the PAGE_OFFSET
+is kept constant at 0xFFF0000000000000 (corresponding to 52-bit),
+this obviates the need for an extra variable read. The physvirt
+offset and vmemmap offsets are computed at early boot to enable
+this logic.
+
+As a single binary will need to support both 48-bit and 52-bit VA
+spaces, the VMEMMAP must be sized large enough for 52-bit VAs and
+also must be sized large enough to accommodate a fixed PAGE_OFFSET.
+
+Most code in the kernel should not need to consider the VA_BITS, for
+code that does need to know the VA size the variables are
+defined as follows:
+
+VA_BITS constant the *maximum* VA space size
+
+VA_BITS_MIN constant the *minimum* VA space size
+
+vabits_actual variable the *actual* VA space size
+
+
+Maximum and minimum sizes can be useful to ensure that buffers are
+sized large enough or that addresses are positioned close enough for
+the "worst" case.
+
+52-bit userspace VAs
+--------------------
+To maintain compatibility with software that relies on the ARMv8.0
+VA space maximum size of 48-bits, the kernel will, by default,
+return virtual addresses to userspace from a 48-bit range.
+
+Software can "opt-in" to receiving VAs from a 52-bit space by
+specifying an mmap hint parameter that is larger than 48-bit.
+
+For example:
+
+.. code-block:: c
+
+ maybe_high_address = mmap(~0UL, size, prot, flags,...);
+
+It is also possible to build a debug kernel that returns addresses
+from a 52-bit space by enabling the following kernel config options:
+
+.. code-block:: sh
+
+ CONFIG_EXPERT=y && CONFIG_ARM64_FORCE_52BIT=y
+
+Note that this option is only intended for debugging applications
+and should not be used in production.

+===================================
+Memory copy/set instructions (MOPS)
+===================================
+
+A MOPS memory copy/set operation consists of three consecutive CPY* or SET*
+instructions: a prologue, main and epilogue (for example: CPYP, CPYM, CPYE).
+
+A main or epilogue instruction can take a MOPS exception for various reasons,
+for example when a task is migrated to a CPU with a different MOPS
+implementation, or when the instruction's alignment and size requirements are
+not met. The software exception handler is then expected to reset the registers
+and restart execution from the prologue instruction. Normally this is handled
+by the kernel.
+
+For more details refer to "D1.3.5.7 Memory Copy and Memory Set exceptions" in
+the Arm Architecture Reference Manual DDI 0487K.a (Arm ARM).
+
+.. _arm64_mops_hyp:
+
+Hypervisor requirements
+-----------------------
+
+A hypervisor running a Linux guest must handle all MOPS exceptions from the
+guest kernel, as Linux may not be able to handle the exception at all times.
+For example, a MOPS exception can be taken when the hypervisor migrates a vCPU
+to another physical CPU with a different MOPS implementation.
+
+To do this, the hypervisor must:
+
+ - Set HCRX_EL2.MCE2 to 1 so that the exception is taken to the hypervisor.
+
+ - Have an exception handler that implements the algorithm from the Arm ARM
+ rules CNTMJ and MWFQH.
+
+ - Set the guest's PSTATE.SS to 0 in the exception handler, to handle a
+ potential step of the current instruction.
+
+ Note: Clearing PSTATE.SS is needed so that a single step exception is taken
+ on the next instruction (the prologue instruction). Otherwise prologue
+ would get silently stepped over and the single step exception taken on the
+ main instruction. Note that if the guest instruction is not being stepped
+ then clearing PSTATE.SS has no effect.

+Perf Event Attributes
+=====================
+
+:Author: Andrew Murray <andrew.murray@arm.com>
+:Date: 2019-03-06
+
+exclude_user
+------------
+
+This attribute excludes userspace.
+
+Userspace always runs at EL0 and thus this attribute will exclude EL0.
+
+
+exclude_kernel
+--------------
+
+This attribute excludes the kernel.
+
+The kernel runs at EL2 with VHE and EL1 without. Guest kernels always run
+at EL1.
+
+For the host this attribute will exclude EL1 and additionally EL2 on a VHE
+system.
+
+For the guest this attribute will exclude EL1. Please note that EL2 is
+never counted within a guest.
+
+
+exclude_hv
+----------
+
+This attribute excludes the hypervisor.
+
+For a VHE host this attribute is ignored as we consider the host kernel to
+be the hypervisor.
+
+For a non-VHE host this attribute will exclude EL2 as we consider the
+hypervisor to be any code that runs at EL2 which is predominantly used for
+guest/host transitions.
+
+For the guest this attribute has no effect. Please note that EL2 is
+never counted within a guest.
+
+
+exclude_host / exclude_guest
+----------------------------
+
+These attributes exclude the KVM host and guest, respectively.
+
+The KVM host may run at EL0 (userspace), EL1 (non-VHE kernel) and EL2 (VHE
+kernel or non-VHE hypervisor).
+
+The KVM guest may run at EL0 (userspace) and EL1 (kernel).
+
+Due to the overlapping exception levels between host and guests we cannot
+exclusively rely on the PMU's hardware exception filtering - therefore we
+must enable/disable counting on the entry and exit to the guest. This is
+performed differently on VHE and non-VHE systems.
+
+For non-VHE systems we exclude EL2 for exclude_host - upon entering and
+exiting the guest we disable/enable the event as appropriate based on the
+exclude_host and exclude_guest attributes.
+
+For VHE systems we exclude EL1 for exclude_guest and exclude both EL0,EL2
+for exclude_host. Upon entering and exiting the guest we modify the event
+to include/exclude EL0 as appropriate based on the exclude_host and
+exclude_guest attributes.
+
+The statements above also apply when these attributes are used within a
+non-VHE guest however please note that EL2 is never counted within a guest.
+
+
+Accuracy
+--------
+
+On non-VHE hosts we enable/disable counters on the entry/exit of host/guest
+transition at EL2 - however there is a period of time between
+enabling/disabling the counters and entering/exiting the guest. We are
+able to eliminate counters counting host events on the boundaries of guest
+entry/exit when counting guest events by filtering out EL2 for
+exclude_host. However when using !exclude_hv there is a small blackout
+window at the guest entry/exit where host events are not captured.
+
+On VHE systems there are no blackout windows.
+
+Perf Userspace PMU Hardware Counter Access
+==========================================
+
+Overview
+--------
+The perf userspace tool relies on the PMU to monitor events. It offers an
+abstraction layer over the hardware counters since the underlying
+implementation is cpu-dependent.
+Arm64 allows userspace tools to have access to the registers storing the
+hardware counters' values directly.
+
+This targets specifically self-monitoring tasks in order to reduce the overhead
+by directly accessing the registers without having to go through the kernel.
+
+How-to
+------
+The focus is set on the armv8 PMUv3 which makes sure that the access to the pmu
+registers is enabled and that the userspace has access to the relevant
+information in order to use them.
+
+In order to have access to the hardware counters, the global sysctl
+kernel/perf_user_access must first be enabled:
+
+.. code-block:: sh
+
+ echo 1 > /proc/sys/kernel/perf_user_access
+
+It is necessary to open the event using the perf tool interface with config1:1
+attr bit set: the sys_perf_event_open syscall returns a fd which can
+subsequently be used with the mmap syscall in order to retrieve a page of memory
+containing information about the event. The PMU driver uses this page to expose
+to the user the hardware counter's index and other necessary data. Using this
+index enables the user to access the PMU registers using the `mrs` instruction.
+Access to the PMU registers is only valid while the sequence lock is unchanged.
+In particular, the PMSELR_EL0 register is zeroed each time the sequence lock is
+changed.
+
+The userspace access is supported in libperf using the perf_evsel__mmap()
+and perf_evsel__read() functions. See `tools/lib/perf/tests/test-evsel.c`_ for
+an example.
+
+About heterogeneous systems
+---------------------------
+On heterogeneous systems such as big.LITTLE, userspace PMU counter access can
+only be enabled when the tasks are pinned to a homogeneous subset of cores and
+the corresponding PMU instance is opened by specifying the 'type' attribute.
+The use of generic event types is not supported in this case.
+
+Have a look at `tools/perf/arch/arm64/tests/user-events.c`_ for an example. It
+can be run using the perf tool to check that the access to the registers works
+correctly from userspace:
+
+.. code-block:: sh
+
+ perf test -v user
+
+About chained events and counter sizes
+--------------------------------------
+The user can request either a 32-bit (config1:0 == 0) or 64-bit (config1:0 == 1)
+counter along with userspace access. The sys_perf_event_open syscall will fail
+if a 64-bit counter is requested and the hardware doesn't support 64-bit
+counters. Chained events are not supported in conjunction with userspace counter
+access. If a 32-bit counter is requested on hardware with 64-bit counters, then
+userspace must treat the upper 32-bits read from the counter as UNKNOWN. The
+'pmc_width' field in the user page will indicate the valid width of the counter
+and should be used to mask the upper bits as needed.

+Event Counting Threshold
+==========================================
+
+Overview
+--------
+
+FEAT_PMUv3_TH (Armv8.8) permits a PMU counter to increment only on
+events whose count meets a specified threshold condition. For example if
+threshold_compare is set to 2 ('Greater than or equal'), and the
+threshold is set to 2, then the PMU counter will now only increment by
+when an event would have previously incremented the PMU counter by 2 or
+more on a single processor cycle.
+
+To increment by 1 after passing the threshold condition instead of the
+number of events on that cycle, add the 'threshold_count' option to the
+commandline.
+
+How-to
+------
+
+These are the parameters for controlling the feature:
+
+.. list-table::
+ :header-rows: 1
+
+ * - Parameter
+ - Description
+ * - threshold
+ - Value to threshold the event by. A value of 0 means that
+ thresholding is disabled and the other parameters have no effect.
+ * - threshold_compare
+ - | Comparison function to use, with the following values supported:
+ |
+ | 0: Not-equal
+ | 1: Equals
+ | 2: Greater-than-or-equal
+ | 3: Less-than
+ * - threshold_count
+ - If this is set, count by 1 after passing the threshold condition
+ instead of the value of the event on this cycle.
+
+The threshold, threshold_compare and threshold_count values can be
+provided per event, for example:
+
+.. code-block:: sh
+
+ perf stat -e stall_slot/threshold=2,threshold_compare=2/ \
+ -e dtlb_walk/threshold=10,threshold_compare=3,threshold_count/
+
+In this example the stall_slot event will count by 2 or more on every
+cycle where 2 or more stalls happen. And dtlb_walk will count by 1 on
+every cycle where the number of dtlb walks were less than 10.
+
+The maximum supported threshold value can be read from the caps of each
+PMU, for example:
+
+.. code-block:: sh
+
+ cat /sys/bus/event_source/devices/armv8_pmuv3/caps/threshold_max
+
+ 0x000000ff
+
+If a value higher than this is given, then opening the event will result
+in an error. The highest possible maximum is 4095, as the config field
+for threshold is limited to 12 bits, and the Perf tool will refuse to
+parse higher values.
+
+If the PMU doesn't support FEAT_PMUv3_TH, then threshold_max will read
+0, and attempting to set a threshold value will also result in an error.
+threshold_max will also read as 0 on aarch32 guests, even if the host
+is running on hardware with the feature.

+======================
+Kernel page table dump
+======================
+
+ptdump is a debugfs interface that provides a detailed dump of the
+kernel page tables. It offers a comprehensive overview of the kernel
+virtual memory layout as well as the attributes associated with the
+various regions in a human-readable format. It is useful to dump the
+kernel page tables to verify permissions and memory types. Examining the
+page table entries and permissions helps identify potential security
+vulnerabilities such as mappings with overly permissive access rights or
+improper memory protections.
+
+Memory hotplug allows dynamic expansion or contraction of available
+memory without requiring a system reboot. To maintain the consistency
+and integrity of the memory management data structures, arm64 makes use
+of the ``mem_hotplug_lock`` semaphore in write mode. Additionally, in
+read mode, ``mem_hotplug_lock`` supports an efficient implementation of
+``get_online_mems()`` and ``put_online_mems()``. These protect the
+offlining of memory being accessed by the ptdump code.
+
+In order to dump the kernel page tables, enable the following
+configurations and mount debugfs::
+
+ CONFIG_PTDUMP_DEBUGFS=y
+
+ mount -t debugfs nodev /sys/kernel/debug
+ cat /sys/kernel/debug/kernel_page_tables
+
+On analysing the output of ``cat /sys/kernel/debug/kernel_page_tables``
+one can derive information about the virtual address range of the entry,
+followed by size of the memory region covered by this entry, the
+hierarchical structure of the page tables and finally the attributes
+associated with each page. The page attributes provide information about
+access permissions, execution capability, type of mapping such as leaf
+level PTE or block level PGD, PMD and PUD, and access status of a page
+within the kernel memory. Assessing these attributes can assist in
+understanding the memory layout, access patterns and security
+characteristics of the kernel pages.

+Silicon Errata and Software Workarounds
+=======================================
+
+Author: Will Deacon <will.deacon@arm.com>
+
+Date : 27 November 2015
+
+It is an unfortunate fact of life that hardware is often produced with
+so-called "errata", which can cause it to deviate from the architecture
+under specific circumstances. For hardware produced by ARM, these
+errata are broadly classified into the following categories:
+
+ ========== ========================================================
+ Category A A critical error without a viable workaround.
+ Category B A significant or critical error with an acceptable
+ workaround.
+ Category C A minor error that is not expected to occur under normal
+ operation.
+ ========== ========================================================
+
+For more information, consult one of the "Software Developers Errata
+Notice" documents available on infocenter.arm.com (registration
+required).
+
+As far as Linux is concerned, Category B errata may require some special
+treatment in the operating system. For example, avoiding a particular
+sequence of code, or configuring the processor in a particular way. A
+less common situation may require similar actions in order to declassify
+a Category A erratum into a Category C erratum. These are collectively
+known as "software workarounds" and are only required in the minority of
+cases (e.g. those cases that both require a non-secure workaround *and*
+can be triggered by Linux).
+
+For software workarounds that may adversely impact systems unaffected by
+the erratum in question, a Kconfig entry is added under "Kernel
+Features" -> "ARM errata workarounds via the alternatives framework".
+With the exception of workarounds for errata deemed "rare" by Arm, these
+are enabled by default and patched in at runtime when an affected CPU is
+detected. For less-intrusive workarounds, a Kconfig option is not
+available and the code is structured (preferably with a comment) in such
+a way that the erratum will not be hit.
+
+This approach can make it slightly onerous to determine exactly which
+errata are worked around in an arbitrary kernel source tree, so this
+file acts as a registry of software workarounds in the Linux Kernel and
+will be updated when new workarounds are committed and backported to
+stable kernels.

+=========================
+Introduction to LoongArch
+=========================
+
+LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V. There are
+currently 3 variants: a reduced 32-bit version (LA32R), a standard 32-bit
+version (LA32S) and a 64-bit version (LA64). There are 4 privilege levels
+(PLVs) defined in LoongArch: PLV0~PLV3, from high to low. Kernel runs at PLV0
+while applications run at PLV3. This document introduces the registers, basic
+instruction set, virtual memory and some other topics of LoongArch.
+
+Registers
+=========
+
+LoongArch registers include general purpose registers (GPRs), floating point
+registers (FPRs), vector registers (VRs) and control status registers (CSRs)
+used in privileged mode (PLV0).
+
+GPRs
+----
+
+LoongArch has 32 GPRs ( ``$r0`` ~ ``$r31`` ); each one is 32-bit wide in LA32
+and 64-bit wide in LA64. ``$r0`` is hard-wired to zero, and the other registers
+are not architecturally special. (Except ``$r1``, which is hard-wired as the
+link register of the BL instruction.)
+
+The kernel uses a variant of the LoongArch register convention, as described in
+the LoongArch ELF psABI spec, in :ref:`References <loongarch-references>`:
+
+================= =============== =================== ============
+Name Alias Usage Preserved
+ across calls
+================= =============== =================== ============
+``$r0`` ``$zero`` Constant zero Unused
+``$r1`` ``$ra`` Return address No
+``$r2`` ``$tp`` TLS/Thread pointer Unused
+``$r3`` ``$sp`` Stack pointer Yes
+``$r4``-``$r11`` ``$a0``-``$a7`` Argument registers No
+``$r4``-``$r5`` ``$v0``-``$v1`` Return value No
+``$r12``-``$r20`` ``$t0``-``$t8`` Temp registers No
+``$r21`` ``$u0`` Percpu base address Unused
+``$r22`` ``$fp`` Frame pointer Yes
+``$r23``-``$r31`` ``$s0``-``$s8`` Static registers Yes
+================= =============== =================== ============
+
+.. Note::
+ The register ``$r21`` is reserved in the ELF psABI, but used by the Linux
+ kernel for storing the percpu base address. It normally has no ABI name,
+ but is called ``$u0`` in the kernel. You may also see ``$v0`` or ``$v1``
+ in some old code,however they are deprecated aliases of ``$a0`` and ``$a1``
+ respectively.
+
+FPRs
+----
+
+LoongArch has 32 FPRs ( ``$f0`` ~ ``$f31`` ) when FPU is present. Each one is
+64-bit wide on the LA64 cores.
+
+The floating-point register convention is the same as described in the
+LoongArch ELF psABI spec:
+
+================= ================== =================== ============
+Name Alias Usage Preserved
+ across calls
+================= ================== =================== ============
+``$f0``-``$f7`` ``$fa0``-``$fa7`` Argument registers No
+``$f0``-``$f1`` ``$fv0``-``$fv1`` Return value No
+``$f8``-``$f23`` ``$ft0``-``$ft15`` Temp registers No
+``$f24``-``$f31`` ``$fs0``-``$fs7`` Static registers Yes
+================= ================== =================== ============
+
+.. Note::
+ You may see ``$fv0`` or ``$fv1`` in some old code, however they are
+ deprecated aliases of ``$fa0`` and ``$fa1`` respectively.
+
+VRs
+----
+
+There are currently 2 vector extensions to LoongArch:
+
+- LSX (Loongson SIMD eXtension) with 128-bit vectors,
+- LASX (Loongson Advanced SIMD eXtension) with 256-bit vectors.
+
+LSX brings ``$v0`` ~ ``$v31`` while LASX brings ``$x0`` ~ ``$x31`` as the vector
+registers.
+
+The VRs overlap with FPRs: for example, on a core implementing LSX and LASX,
+the lower 128 bits of ``$x0`` is shared with ``$v0``, and the lower 64 bits of
+``$v0`` is shared with ``$f0``; same with all other VRs.
+
+CSRs
+----
+
+CSRs can only be accessed from privileged mode (PLV0):

+
+Virtual Memory
+==============
+
+LoongArch supports direct-mapped virtual memory and page-mapped virtual memory.
+
+Direct-mapped virtual memory is configured by CSR.DMWn (n=0~3), it has a simple
+relationship between virtual address (VA) and physical address (PA)::
+
+ VA = PA + FixedOffset
+
+Page-mapped virtual memory has arbitrary relationship between VA and PA, which
+is recorded in TLB and page tables. LoongArch's TLB includes a fully-associative
+MTLB (Multiple Page Size TLB) and set-associative STLB (Single Page Size TLB).
+
+By default, the whole virtual address space of LA32 is configured like this:
+
+============ =========================== =============================
+Name Address Range Attributes
+============ =========================== =============================
+``UVRANGE`` ``0x00000000 - 0x7FFFFFFF`` Page-mapped, Cached, PLV0~3
+``KPRANGE0`` ``0x80000000 - 0x9FFFFFFF`` Direct-mapped, Uncached, PLV0
+``KPRANGE1`` ``0xA0000000 - 0xBFFFFFFF`` Direct-mapped, Cached, PLV0
+``KVRANGE`` ``0xC0000000 - 0xFFFFFFFF`` Page-mapped, Cached, PLV0
+============ =========================== =============================
+
+User mode (PLV3) can only access UVRANGE. For direct-mapped KPRANGE0 and
+KPRANGE1, PA is equal to VA with bit30~31 cleared. For example, the uncached
+direct-mapped VA of 0x00001000 is 0x80001000, and the cached direct-mapped
+VA of 0x00001000 is 0xA0001000.
+
+By default, the whole virtual address space of LA64 is configured like this:
+
+============ ====================== ======================================
+Name Address Range Attributes
+============ ====================== ======================================
+``XUVRANGE`` ``0x0000000000000000 - Page-mapped, Cached, PLV0~3
+ 0x3FFFFFFFFFFFFFFF``
+``XSPRANGE`` ``0x4000000000000000 - Direct-mapped, Cached / Uncached, PLV0
+ 0x7FFFFFFFFFFFFFFF``
+``XKPRANGE`` ``0x8000000000000000 - Direct-mapped, Cached / Uncached, PLV0
+ 0xBFFFFFFFFFFFFFFF``
+``XKVRANGE`` ``0xC000000000000000 - Page-mapped, Cached, PLV0
+ 0xFFFFFFFFFFFFFFFF``
+============ ====================== ======================================
+
+User mode (PLV3) can only access XUVRANGE. For direct-mapped XSPRANGE and
+XKPRANGE, PA is equal to VA with bits 60~63 cleared, and the cache attribute
+is configured by bits 60~61 in VA: 0 is for strongly-ordered uncached, 1 is
+for coherent cached, and 2 is for weakly-ordered uncached.
+
+Currently we only use XKPRANGE for direct mapping and XSPRANGE is reserved.
+
+To put this in action: the strongly-ordered uncached direct-mapped VA (in
+XKPRANGE) of 0x00000000_00001000 is 0x80000000_00001000, the coherent cached
+direct-mapped VA (in XKPRANGE) of 0x00000000_00001000 is 0x90000000_00001000,
+and the weakly-ordered uncached direct-mapped VA (in XKPRANGE) of 0x00000000
+_00001000 is 0xA0000000_00001000.
+
+Relationship of Loongson and LoongArch
+======================================
+
+LoongArch is a RISC ISA which is different from any other existing ones, while
+Loongson is a family of processors. Loongson includes 3 series: Loongson-1 is
+the 32-bit processor series, Loongson-2 is the low-end 64-bit processor series,
+and Loongson-3 is the high-end 64-bit processor series. Old Loongson is based on
+MIPS, while New Loongson is based on LoongArch. Take Loongson-3 as an example:
+Loongson-3A1000/3B1500/3A2000/3A3000/3A4000 are MIPS-compatible, while Loongson-
+3A5000 (and future revisions) are all based on LoongArch.

+IRQ chip model (hierarchy) of LoongArch
+=======================================
+
+Currently, LoongArch based processors (e.g. Loongson-3A5000) can only work together
+with LS7A chipsets. The irq chips in LoongArch computers include CPUINTC (CPU Core
+Interrupt Controller), LIOINTC (Legacy I/O Interrupt Controller), EIOINTC (Extended
+I/O Interrupt Controller), HTVECINTC (Hyper-Transport Vector Interrupt Controller),
+PCH-PIC (Main Interrupt Controller in LS7A chipset), PCH-LPC (LPC Interrupt Controller
+in LS7A chipset) and PCH-MSI (MSI Interrupt Controller).
+
+CPUINTC is a per-core controller (in CPU), LIOINTC/EIOINTC/HTVECINTC are per-package
+controllers (in CPU), while PCH-PIC/PCH-LPC/PCH-MSI are controllers out of CPU (i.e.,
+in chipsets). These controllers (in other words, irqchips) are linked in a hierarchy,
+and there are two models of hierarchy (legacy model and extended model).
+
+Legacy IRQ model
+================
+
+In this model, IPI (Inter-Processor Interrupt) and CPU Local Timer interrupt go
+to CPUINTC directly, CPU UARTS interrupts go to LIOINTC, while all other devices
+interrupts go to PCH-PIC/PCH-LPC/PCH-MSI and gathered by HTVECINTC, and then go
+to LIOINTC, and then CPUINTC::

+Description
+-----------
+V-EIOINTC (Virtual Extended I/O Interrupt Controller) is an extension of
+EIOINTC, it only works in VM mode which runs in KVM hypervisor. Interrupts can
+be routed to up to four vCPUs via standard EIOINTC, however with V-EIOINTC
+interrupts can be routed to up to 256 virtual cpus.
+
+With standard EIOINTC, interrupt routing setting includes two parts: eight
+bits for CPU selection and four bits for CPU IP (Interrupt Pin) selection.
+For CPU selection there is four bits for EIOINTC node selection, four bits
+for EIOINTC CPU selection. Bitmap method is used for CPU selection and
+CPU IP selection, so interrupt can only route to CPU0 - CPU3 and IP0-IP3 in
+one EIOINTC node.
+
+With V-EIOINTC it supports to route more CPUs and CPU IP (Interrupt Pin),
+there are two newly added registers with V-EIOINTC.
+
+EXTIOI_VIRT_FEATURES
+--------------------
+This register is read-only register, which indicates supported features with
+V-EIOINTC. Feature EXTIOI_HAS_INT_ENCODE and EXTIOI_HAS_CPU_ENCODE is added.
+
+Feature EXTIOI_HAS_INT_ENCODE is part of standard EIOINTC. If it is 1, it
+indicates that CPU Interrupt Pin selection can be normal method rather than
+bitmap method, so interrupt can be routed to IP0 - IP15.
+
+Feature EXTIOI_HAS_CPU_ENCODE is extension of V-EIOINTC. If it is 1, it
+indicates that CPU selection can be normal method rather than bitmap method,
+so interrupt can be routed to CPU0 - CPU255.
+
+EXTIOI_VIRT_CONFIG
+------------------
+This register is read-write register, for compatibility interrupt routed uses
+the default method which is the same with standard EIOINTC. If the bit is set
+with 1, it indicated HW to use normal method rather than bitmap method.
+
+Advanced Extended IRQ model
+===========================
+
+In this model, IPI (Inter-Processor Interrupt) and CPU Local Timer interrupt go
+to CPUINTC directly, CPU UARTS interrupts go to LIOINTC, PCH-MSI interrupts go
+to AVECINTC, and then go to CPUINTC directly, while all other devices interrupts
+go to PCH-PIC/PCH-LPC and gathered by EIOINTC, and then go to CPUINTC directly::

+In order to build and run Linux for OpenRISC, you'll need at least a basic
+toolchain and, perhaps, the architectural simulator. Steps to get these bits
+in place are outlined here.
+
+1) Toolchain
+
+Toolchain binaries can be obtained from openrisc.io or our github releases page.
+Instructions for building the different toolchains can be found on openrisc.io
+or Stafford's toolchain build and release scripts.
+
+ ========== ==========================================================
+ binaries https://github.com/stffrdhrn/or1k-toolchain-build/releases
+ toolchains https://openrisc.io/software
+ building https://github.com/stffrdhrn/or1k-toolchain-build
+ ========== ==========================================================
+
+2) Building
+
+Build the Linux kernel as usual::
+
+ make ARCH=openrisc CROSS_COMPILE="or1k-linux-" defconfig
+ make ARCH=openrisc CROSS_COMPILE="or1k-linux-"
+
+If you want to embed initramfs in the kernel, also pass ``CONFIG_INITRAMFS_SOURCE``. For example::
+
+ make ARCH=openrisc CROSS_COMPILE="or1k-linux-" CONFIG_INITRAMFS_SOURCE="path/to/rootfs path/to/devnodes"
+
+For more information on this, please check Documentation/filesystems/ramfs-rootfs-initramfs.rst.
+
+3) Running on FPGA (optional)
+
+The OpenRISC community typically uses FuseSoC to manage building and programming
+an SoC into an FPGA. The below is an example of programming a De0 Nano
+development board with the OpenRISC SoC. During the build FPGA RTL is code
+downloaded from the FuseSoC IP cores repository and built using the FPGA vendor
+tools. Binaries are loaded onto the board with openocd.
+
+::
+
+ git clone https://github.com/olofk/fusesoc
+ cd fusesoc
+ sudo pip install -e .
+
+ fusesoc init
+ fusesoc build de0_nano
+ fusesoc pgm de0_nano
+
+ openocd -f interface/altera-usb-blaster.cfg \
+ -f board/or1k_generic.cfg
+
+ telnet localhost 4444
+ > init
+ > halt; load_image vmlinux ; reset
+
+4) Running on a Simulator (optional)
+
+QEMU is a processor emulator which we recommend for simulating the OpenRISC
+platform. Please follow the OpenRISC instructions on the QEMU website to get
+Linux running on QEMU. You can build QEMU yourself, but your Linux distribution
+likely provides binary packages to support OpenRISC.
+

+
+Terminology
+===========
+
+In the code, the following particles are used on symbols to limit the scope
+to more or less specific processor implementations:
+
+========= =======================================
+openrisc: the OpenRISC class of processors
+or1k: the OpenRISC 1000 family of processors
+or1200: the OpenRISC 1200 processor

+DeviceTree Booting
+------------------
+
+During the development of the Linux/ppc64 kernel, and more specifically, the
+addition of new platform types outside of the old IBM pSeries/iSeries pair, it
+was decided to enforce some strict rules regarding the kernel entry and
+bootloader <-> kernel interfaces, in order to avoid the degeneration that had
+become the ppc32 kernel entry point and the way a new platform should be added
+to the kernel. The legacy iSeries platform breaks those rules as it predates
+this scheme, but no new board support will be accepted in the main tree that
+doesn't follow them properly. In addition, since the advent of the arch/powerpc
+merged architecture for ppc32 and ppc64, new 32-bit platforms and 32-bit
+platforms which move into arch/powerpc will be required to use these rules as
+well.
+
+The main requirement that will be defined in more detail below is the presence
+of a device-tree whose format is defined after Open Firmware specification.
+However, in order to make life easier to embedded board vendors, the kernel
+doesn't require the device-tree to represent every device in the system and only
+requires some nodes and properties to be present. For example, the kernel does
+not require you to create a node for every PCI device in the system. It is a
+requirement to have a node for PCI host bridges in order to provide interrupt
+routing information and memory/IO ranges, among others. It is also recommended
+to define nodes for on chip devices and other buses that don't specifically fit
+in an existing OF specification. This creates a great flexibility in the way the
+kernel can then probe those and match drivers to device, without having to hard
+code all sorts of tables. It also makes it more flexible for board vendors to do
+minor hardware upgrades without significantly impacting the kernel code or
+cluttering it with special cases.
+
+
+Entry point
+~~~~~~~~~~~
+
+There is one single entry point to the kernel, at the start
+of the kernel image. That entry point supports two calling
+conventions:
+
+ a) Boot from Open Firmware. If your firmware is compatible
+ with Open Firmware (IEEE 1275) or provides an OF compatible
+ client interface API (support for "interpret" callback of
+ forth words isn't required), you can enter the kernel with:
+
+ r5 : OF callback pointer as defined by IEEE 1275
+ bindings to powerpc. Only the 32-bit client interface
+ is currently supported
+
+ r3, r4 : address & length of an initrd if any or 0
+
+ The MMU is either on or off; the kernel will run the
+ trampoline located in arch/powerpc/kernel/prom_init.c to
+ extract the device-tree and other information from open
+ firmware and build a flattened device-tree as described
+ in b). prom_init() will then re-enter the kernel using
+ the second method. This trampoline code runs in the
+ context of the firmware, which is supposed to handle all
+ exceptions during that time.
+
+ b) Direct entry with a flattened device-tree block. This entry
+ point is called by a) after the OF trampoline and can also be
+ called directly by a bootloader that does not support the Open
+ Firmware client interface. It is also used by "kexec" to
+ implement "hot" booting of a new kernel from a previous
+ running one. This method is what I will describe in more
+ details in this document, as method a) is simply standard Open
+ Firmware, and thus should be implemented according to the
+ various standard documents defining it and its binding to the
+ PowerPC platform. The entry point definition then becomes:
+
+ r3 : physical pointer to the device-tree block
+ (defined in chapter II) in RAM
+
+ r4 : physical pointer to the kernel itself. This is
+ used by the assembly code to properly disable the MMU
+ in case you are entering the kernel with MMU enabled
+ and a non-1:1 mapping.
+
+ r5 : NULL (as to differentiate with method a)
+
+Note about SMP entry: Either your firmware puts your other
+CPUs in some sleep loop or spin loop in ROM where you can get
+them out via a soft reset or some other means, in which case
+you don't need to care, or you'll have to enter the kernel
+with all CPUs. The way to do that with method b) will be
+described in a later revision of this document.
+
+Board supports (platforms) are not exclusive config options. An
+arbitrary set of board supports can be built in a single kernel
+image. The kernel will "know" what set of functions to use for a
+given platform based on the content of the device-tree. Thus, you
+should:
+
+ a) add your platform support as a _boolean_ option in
+ arch/powerpc/Kconfig, following the example of PPC_PSERIES
+ and PPC_PMAC. The latter is probably a good
+ example of a board support to start from.
+
+ b) create your main platform file as
+ "arch/powerpc/platforms/myplatform/myboard_setup.c" and add it
+ to the Makefile under the condition of your ``CONFIG_``
+ option. This file will define a structure of type "ppc_md"
+ containing the various callbacks that the generic code will
+ use to get to your platform specific code
+
+A kernel image may support multiple platforms, but only if the
+platforms feature the same core architecture. A single kernel build
+cannot support both configurations with Book E and configurations
+with classic Powerpc architectures.

+==========================================
+DEXCR (Dynamic Execution Control Register)
+==========================================
+
+Overview
+========
+
+The DEXCR is a privileged special purpose register (SPR) introduced in
+PowerPC ISA 3.1B (Power10) that allows per-cpu control over several dynamic
+execution behaviours. These behaviours include speculation (e.g., indirect
+branch target prediction) and enabling return-oriented programming (ROP)
+protection instructions.
+
+The execution control is exposed in hardware as up to 32 bits ('aspects') in
+the DEXCR. Each aspect controls a certain behaviour, and can be set or cleared
+to enable/disable the aspect. There are several variants of the DEXCR for
+different purposes:
+
+DEXCR
+ A privileged SPR that can control aspects for userspace and kernel space
+HDEXCR
+ A hypervisor-privileged SPR that can control aspects for the hypervisor and
+ enforce aspects for the kernel and userspace.
+UDEXCR
+ An optional ultravisor-privileged SPR that can control aspects for the ultravisor.
+
+Userspace can examine the current DEXCR state using a dedicated SPR that
+provides a non-privileged read-only view of the userspace DEXCR aspects.
+There is also an SPR that provides a read-only view of the hypervisor enforced
+aspects, which ORed with the userspace DEXCR view gives the effective DEXCR
+state for a process.
+
+
+Configuration
+=============
+
+prctl
+-----
+
+A process can control its own userspace DEXCR value using the
+``PR_PPC_GET_DEXCR`` and ``PR_PPC_SET_DEXCR`` pair of
+:manpage:`prctl(2)` commands. These calls have the form::
+
+ prctl(PR_PPC_GET_DEXCR, unsigned long which, 0, 0, 0);
+ prctl(PR_PPC_SET_DEXCR, unsigned long which, unsigned long ctrl, 0, 0);
+
+The possible 'which' and 'ctrl' values are as follows. Note there is no relation
+between the 'which' value and the DEXCR aspect's index.
+
+.. flat-table::
+ :header-rows: 1
+ :widths: 2 7 1
+
+ * - ``prctl()`` which
+ - Aspect name
+ - Aspect index
+
+ * - ``PR_PPC_DEXCR_SBHE``
+ - Speculative Branch Hint Enable (SBHE)
+ - 0
+
+ * - ``PR_PPC_DEXCR_IBRTPD``
+ - Indirect Branch Recurrent Target Prediction Disable (IBRTPD)
+ - 3
+
+ * - ``PR_PPC_DEXCR_SRAPD``
+ - Subroutine Return Address Prediction Disable (SRAPD)
+ - 4
+
+ * - ``PR_PPC_DEXCR_NPHIE``
+ - Non-Privileged Hash Instruction Enable (NPHIE)
+ - 5
+
+.. flat-table::
+ :header-rows: 1
+ :widths: 2 8
+
+ * - ``prctl()`` ctrl
+ - Meaning
+
+ * - ``PR_PPC_DEXCR_CTRL_EDITABLE``
+ - This aspect can be configured with PR_PPC_SET_DEXCR (get only)
+
+ * - ``PR_PPC_DEXCR_CTRL_SET``
+ - This aspect is set / set this aspect
+
+ * - ``PR_PPC_DEXCR_CTRL_CLEAR``
+ - This aspect is clear / clear this aspect
+
+ * - ``PR_PPC_DEXCR_CTRL_SET_ONEXEC``
+ - This aspect will be set after exec / set this aspect after exec
+
+ * - ``PR_PPC_DEXCR_CTRL_CLEAR_ONEXEC``
+ - This aspect will be clear after exec / clear this aspect after exec
+
+Note that
+
+* which is a plain value, not a bitmask. Aspects must be worked with individually.
+
+* ctrl is a bitmask. ``PR_PPC_GET_DEXCR`` returns both the current and onexec
+ configuration. For example, ``PR_PPC_GET_DEXCR`` may return
+ ``PR_PPC_DEXCR_CTRL_EDITABLE | PR_PPC_DEXCR_CTRL_SET |
+ PR_PPC_DEXCR_CTRL_CLEAR_ONEXEC``. This would indicate the aspect is currently
+ set, it will be cleared when you run exec, and you can change this with the
+ ``PR_PPC_SET_DEXCR`` prctl.
+
+* The set/clear terminology refers to setting/clearing the bit in the DEXCR.
+ For example::
+
+ prctl(PR_PPC_SET_DEXCR, PR_PPC_DEXCR_IBRTPD, PR_PPC_DEXCR_CTRL_SET, 0, 0);
+
+ will set the IBRTPD aspect bit in the DEXCR, causing indirect branch prediction
+ to be disabled.
+
+* The status returned by ``PR_PPC_GET_DEXCR`` represents what value the process
+ would like applied. It does not include any alternative overrides, such as if
+ the hypervisor is enforcing the aspect be set. To see the true DEXCR state
+ software should read the appropriate SPRs directly.
+
+* The aspect state when starting a process is copied from the parent's state on
+ :manpage:`fork(2)`. The state is reset to a fixed value on
+ :manpage:`execve(2)`. The PR_PPC_SET_DEXCR prctl() can control both of these
+ values.
+
+* The ``*_ONEXEC`` controls do not change the current process's DEXCR.
+
+Use ``PR_PPC_SET_DEXCR`` with one of ``PR_PPC_DEXCR_CTRL_SET`` or
+``PR_PPC_DEXCR_CTRL_CLEAR`` to edit a given aspect.
+
+Common error codes for both getting and setting the DEXCR are as follows:
+
+.. flat-table::
+ :header-rows: 1
+ :widths: 2 8
+
+ * - Error
+ - Meaning
+
+ * - ``EINVAL``
+ - The DEXCR is not supported by the kernel.
+
+ * - ``ENODEV``
+ - The aspect is not recognised by the kernel or not supported by the
+ hardware.
+
+``PR_PPC_SET_DEXCR`` may also report the following error codes:
+
+.. flat-table::
+ :header-rows: 1
+ :widths: 2 8
+
+ * - Error
+ - Meaning
+
+ * - ``EINVAL``
+ - The ctrl value contains unrecognised flags.
+
+ * - ``EINVAL``
+ - The ctrl value contains mutually conflicting flags (e.g.,
+ ``PR_PPC_DEXCR_CTRL_SET | PR_PPC_DEXCR_CTRL_CLEAR``)
+
+ * - ``EPERM``
+ - This aspect cannot be modified with prctl() (check for the
+ PR_PPC_DEXCR_CTRL_EDITABLE flag with PR_PPC_GET_DEXCR).
+
+ * - ``EPERM``
+ - The process does not have sufficient privilege to perform the operation.
+ For example, clearing NPHIE on exec is a privileged operation (a process
+ can still clear its own NPHIE aspect without privileges).
+
+This interface allows a process to control its own DEXCR aspects, and also set
+the initial DEXCR value for any children in its process tree (up to the next
+child to use an ``*_ONEXEC`` control). This allows fine-grained control over the
+default value of the DEXCR, for example allowing containers to run with different
+default values.
+
+
+coredump and ptrace
+===================
+
+The userspace values of the DEXCR and HDEXCR (in this order) are exposed under
+``NT_PPC_DEXCR``. These are each 64 bits and readonly, and are intended to
+assist with core dumps. The DEXCR may be made writable in future. The top 32
+bits of both registers (corresponding to the non-userspace bits) are masked off.
+
+If the kernel config ``CONFIG_CHECKPOINT_RESTORE`` is enabled, then
+``NT_PPC_HASHKEYR`` is available and exposes the HASHKEYR value of the process
+for reading and writing. This is a tradeoff between increased security and
+checkpoint/restore support: a process should normally have no need to know its
+secret key, but restoring a process requires setting its original key. The key
+therefore appears in core dumps, and an attacker may be able to retrieve it from
+a coredump and effectively bypass ROP protection on any threads that share this
+key (potentially all threads from the same parent that have not run ``exec()``).

+
+==================
+POWERPC ELF HWCAPs
+==================
+
+This document describes the usage and semantics of the powerpc ELF HWCAPs.
+
+
+1. Introduction
+---------------
+
+Some hardware or software features are only available on some CPU
+implementations, and/or with certain kernel configurations, but have no other
+discovery mechanism available to userspace code. The kernel exposes the
+presence of these features to userspace through a set of flags called HWCAPs,
+exposed in the auxiliary vector.
+
+Userspace software can test for features by acquiring the AT_HWCAP or
+AT_HWCAP2 entry of the auxiliary vector, and testing whether the relevant
+flags are set, e.g.::
+
+ bool floating_point_is_present(void)
+ {
+ unsigned long HWCAPs = getauxval(AT_HWCAP);
+ if (HWCAPs & PPC_FEATURE_HAS_FPU)
+ return true;
+
+ return false;
+ }
+
+Where software relies on a feature described by a HWCAP, it should check the
+relevant HWCAP flag to verify that the feature is present before attempting to
+make use of the feature.
+
+HWCAP is the preferred method to test for the presence of a feature rather
+than probing through other means, which may not be reliable or may cause
+unpredictable behaviour.
+
+Software that targets a particular platform does not necessarily have to
+test for required or implied features. For example if the program requires
+FPU, VMX, VSX, it is not necessary to test those HWCAPs, and it may be
+impossible to do so if the compiler generates code requiring those features.
+
+2. Facilities
+-------------
+
+The Power ISA uses the term "facility" to describe a class of instructions,
+registers, interrupts, etc. The presence or absence of a facility indicates
+whether this class is available to be used, but the specifics depend on the
+ISA version. For example, if the VSX facility is available, the VSX
+instructions that can be used differ between the v3.0B and v3.1B ISA
+versions.
+
+3. Categories
+-------------
+
+The Power ISA before v3.0 uses the term "category" to describe certain
+classes of instructions and operating modes which may be optional or
+mutually exclusive, the exact meaning of the HWCAP flag may depend on
+context, e.g., the presence of the BOOKE feature implies that the server
+category is not implemented.
+
+4. HWCAP allocation
+-------------------
+
+HWCAPs are allocated as described in Power Architecture 64-Bit ELF V2 ABI
+Specification (which will be reflected in the kernel's uapi headers).
+
+5. The HWCAPs exposed in AT_HWCAP
+---------------------------------
+
+PPC_FEATURE_32
+ 32-bit CPU
+
+PPC_FEATURE_64
+ 64-bit CPU (userspace may be running in 32-bit mode).
+
+PPC_FEATURE_601_INSTR
+ The processor is PowerPC 601.

+
+PPC_FEATURE_HAS_4xxMAC
+ The processor is 40x or 44x family.
+ Unused in the kernel since 732b32daef80 ("powerpc: Remove core support for 40x")
+
+PPC_FEATURE_UNIFIED_CACHE
+ The processor has a unified L1 cache for instructions and data, as

+ running is not a 601, via other HWCAPs or other means, it is not
+ required to test this bit before using the timebase.
+ Unused in the kernel since f0ed73f3fa2c ("powerpc: Remove PowerPC 601")
+

+===================================
+HTM (Hardware Trace Macro)
+===================================
+
+Athira Rajeev, 2 Mar 2025
+
+.. contents::
+ :depth: 3
+
+
+Basic overview
+==============
+
+H_HTM is used as an interface for executing Hardware Trace Macro (HTM)
+functions, including setup, configuration, control and dumping of the HTM data.
+For using HTM, it is required to setup HTM buffers and HTM operations can
+be controlled using the H_HTM hcall. The hcall can be invoked for any core/chip
+of the system from within a partition itself. To use this feature, a debugfs
+folder called "htmdump" is present under /sys/kernel/debug/powerpc.
+
+
+HTM debugfs example usage
+=========================
+
+.. code-block:: sh
+
+ # ls /sys/kernel/debug/powerpc/htmdump/
+ coreindexonchip htmcaps htmconfigure htmflags htminfo htmsetup
+ htmstart htmstatus htmtype nodalchipindex nodeindex trace
+
+Details on each file:
+
+* nodeindex, nodalchipindex, coreindexonchip specifies which partition to configure the HTM for.
+* htmtype: specifies the type of HTM. Supported target is hardwareTarget.
+* trace: is to read the HTM data.
+* htmconfigure: Configure/Deconfigure the HTM. Writing 1 to the file will configure the trace, writing 0 to the file will do deconfigure.
+* htmstart: start/Stop the HTM. Writing 1 to the file will start the tracing, writing 0 to the file will stop the tracing.
+* htmstatus: get the status of HTM. This is needed to understand the HTM state after each operation.
+* htmsetup: set the HTM buffer size. Size of HTM buffer is in power of 2
+* htminfo: provides the system processor configuration details. This is needed to understand the appropriate values for nodeindex, nodalchipindex, coreindexonchip.
+* htmcaps : provides the HTM capabilities like minimum/maximum buffer size, what kind of tracing the HTM supports etc.
+* htmflags : allows to pass flags to hcall. Currently supports controlling the wrapping of HTM buffer.
+
+To see the system processor configuration details:
+
+.. code-block:: sh
+
+ # cat /sys/kernel/debug/powerpc/htmdump/htminfo > htminfo_file
+
+The result can be interpreted using hexdump.
+
+To collect HTM traces for a partition represented by nodeindex as
+zero, nodalchipindex as 1 and coreindexonchip as 12
+
+.. code-block:: sh
+
+ # cd /sys/kernel/debug/powerpc/htmdump/
+ # echo 2 > htmtype
+ # echo 33 > htmsetup ( sets 8GB memory for HTM buffer, number is size in power of 2 )
+
+This requires a CEC reboot to get the HTM buffers allocated.
+
+.. code-block:: sh
+
+ # cd /sys/kernel/debug/powerpc/htmdump/
+ # echo 2 > htmtype
+ # echo 0 > nodeindex
+ # echo 1 > nodalchipindex
+ # echo 12 > coreindexonchip
+ # echo 1 > htmflags # to set noWrap for HTM buffers
+ # echo 1 > htmconfigure # Configure the HTM
+ # echo 1 > htmstart # Start the HTM
+ # echo 0 > htmstart # Stop the HTM
+ # echo 0 > htmconfigure # Deconfigure the HTM
+ # cat htmstatus # Dump the status of HTM entries as data
+
+Above will set the htmtype and core details, followed by executing respective HTM operation.
+
+Read the HTM trace data
+========================
+
+After starting the trace collection, run the workload
+of interest. Stop the trace collection after required period
+of time, and read the trace file.
+
+.. code-block:: sh
+
+ # cat /sys/kernel/debug/powerpc/htmdump/trace > trace_file
+
+This trace file will contain the relevant instruction traces
+collected during the workload execution. And can be used as
+input file for trace decoders to understand data.
+
+Benefits of using HTM debugfs interface
+=======================================
+
+It is now possible to collect traces for a particular core/chip
+from within any partition of the system and decode it. Through
+this enablement, a small partition can be dedicated to collect the
+trace data and analyze to provide important information for Performance
+analysis, Software tuning, or Hardware debug.

+Nested KVM on POWER
+====================================
+
+Introduction
+============
+
+This document explains how a guest operating system can act as a
+hypervisor and run nested guests through the use of hypercalls, if the
+hypervisor has implemented them. The terms L0, L1, and L2 are used to
+refer to different software entities. L0 is the hypervisor mode entity
+that would normally be called the "host" or "hypervisor". L1 is a
+guest virtual machine that is directly run under L0 and is initiated
+and controlled by L0. L2 is a guest virtual machine that is initiated
+and controlled by L1 acting as a hypervisor.
+
+Existing API
+============
+
+Linux/KVM has had support for Nesting as an L0 or L1 since 2018
+
+The L0 code was added::
+
+ commit 8e3f5fc1045dc49fd175b978c5457f5f51e7a2ce
+ Author: Paul Mackerras <paulus@ozlabs.org>
+ Date: Mon Oct 8 16:31:03 2018 +1100
+ KVM: PPC: Book3S HV: Framework and hcall stubs for nested virtualization
+
+The L1 code was added::
+
+ commit 360cae313702cdd0b90f82c261a8302fecef030a
+ Author: Paul Mackerras <paulus@ozlabs.org>
+ Date: Mon Oct 8 16:31:04 2018 +1100
+ KVM: PPC: Book3S HV: Nested guest entry via hypercall
+
+This API works primarily using a single hcall h_enter_nested(). This
+call made by the L1 to tell the L0 to start an L2 vCPU with the given
+state. The L0 then starts this L2 and runs until an L2 exit condition
+is reached. Once the L2 exits, the state of the L2 is given back to
+the L1 by the L0. The full L2 vCPU state is always transferred from
+and to L1 when the L2 is run. The L0 doesn't keep any state on the L2
+vCPU (except in the short sequence in the L0 on L1 -> L2 entry and L2
+-> L1 exit).
+
+The only state kept by the L0 is the partition table. The L1 registers
+it's partition table using the h_set_partition_table() hcall. All
+other state held by the L0 about the L2s is cached state (such as
+shadow page tables).
+
+The L1 may run any L2 or vCPU without first informing the L0. It
+simply starts the vCPU using h_enter_nested(). The creation of L2s and
+vCPUs is done implicitly whenever h_enter_nested() is called.
+
+In this document, we call this existing API the v1 API.
+
+New PAPR API
+===============
+
+The new PAPR API changes from the v1 API such that the creating L2 and
+associated vCPUs is explicit. In this document, we call this the v2
+API.
+
+h_enter_nested() is replaced with H_GUEST_VCPU_RUN(). Before this can
+be called the L1 must explicitly create the L2 using h_guest_create()
+and any associated vCPUs() created with h_guest_create_vCPU(). Getting
+and setting vCPU state can also be performed using h_guest_{g|s}et
+hcall.
+
+The basic execution flow is for an L1 to create an L2, run it, and
+delete it is:
+
+- L1 and L0 negotiate capabilities with H_GUEST_{G,S}ET_CAPABILITIES()
+ (normally at L1 boot time).
+
+- L1 requests the L0 create an L2 with H_GUEST_CREATE() and receives a token
+
+- L1 requests the L0 create an L2 vCPU with H_GUEST_CREATE_VCPU()
+
+- L1 and L0 communicate the vCPU state using the H_GUEST_{G,S}ET() hcall
+
+- L1 requests the L0 runs the vCPU running H_GUEST_VCPU_RUN() hcall
+
+- L1 deletes L2 with H_GUEST_DELETE()
+
+More details of the individual hcalls follows:
+
+HCALL Details
+=============
+
+This documentation is provided to give an overall understating of the
+API. It doesn't aim to provide all the details required to implement
+an L1 or L0. Latest version of PAPR can be referred to for more details.
+
+All these HCALLs are made by the L1 to the L0.
+
+H_GUEST_GET_CAPABILITIES()
+--------------------------
+
+This is called to get the capabilities of the L0 nested
+hypervisor. This includes capabilities such the CPU versions (eg
+POWER9, POWER10) that are supported as L2s::
+
+ H_GUEST_GET_CAPABILITIES(uint64 flags)
+
+ Parameters:
+ Input:
+ flags: Reserved
+ Output:
+ R3: Return code
+ R4: Hypervisor Supported Capabilities bitmap 1
+
+H_GUEST_SET_CAPABILITIES()
+--------------------------
+
+This is called to inform the L0 of the capabilities of the L1
+hypervisor. The set of flags passed here are the same as
+H_GUEST_GET_CAPABILITIES()
+
+Typically, GET will be called first and then SET will be called with a
+subset of the flags returned from GET. This process allows the L0 and
+L1 to negotiate an agreed set of capabilities::
+
+ H_GUEST_SET_CAPABILITIES(uint64 flags,
+ uint64 capabilitiesBitmap1)
+ Parameters:
+ Input:
+ flags: Reserved
+ capabilitiesBitmap1: Only capabilities advertised through
+ H_GUEST_GET_CAPABILITIES
+ Output:
+ R3: Return code
+ R4: If R3 = H_P2: The number of invalid bitmaps
+ R5: If R3 = H_P2: The index of first invalid bitmap
+
+H_GUEST_CREATE()
+----------------
+
+This is called to create an L2. A unique ID of the L2 created
+(similar to an LPID) is returned, which can be used on subsequent HCALLs to
+identify the L2::
+
+ H_GUEST_CREATE(uint64 flags,
+ uint64 continueToken);
+ Parameters:
+ Input:
+ flags: Reserved
+ continueToken: Initial call set to -1. Subsequent calls,
+ after H_Busy or H_LongBusyOrder has been
+ returned, value that was returned in R4.
+ Output:
+ R3: Return code. Notable:
+ H_Not_Enough_Resources: Unable to create Guest VCPU due to not
+ enough Hypervisor memory. See H_GUEST_CREATE_GET_STATE(flags =
+ takeOwnershipOfVcpuState)
+ R4: If R3 = H_Busy or_H_LongBusyOrder -> continueToken
+
+H_GUEST_CREATE_VCPU()
+---------------------
+
+This is called to create a vCPU associated with an L2. The L2 id
+(returned from H_GUEST_CREATE()) should be passed it. Also passed in
+is a unique (for this L2) vCPUid. This vCPUid is allocated by the
+L1::
+
+ H_GUEST_CREATE_VCPU(uint64 flags,
+ uint64 guestId,
+ uint64 vcpuId);
+ Parameters:
+ Input:
+ flags: Reserved
+ guestId: ID obtained from H_GUEST_CREATE
+ vcpuId: ID of the vCPU to be created. This must be within the
+ range of 0 to 2047
+ Output:
+ R3: Return code. Notable:
+ H_Not_Enough_Resources: Unable to create Guest VCPU due to not
+ enough Hypervisor memory. See H_GUEST_CREATE_GET_STATE(flags =
+ takeOwnershipOfVcpuState)
+
+H_GUEST_GET_STATE()
+-------------------
+
+This is called to get state associated with an L2 (Guest-wide or vCPU specific).
+This info is passed via the Guest State Buffer (GSB), a standard format as
+explained later in this doc, necessary details below:
+
+This can get either L2 wide or vcpu specific information. Examples of
+L2 wide is the timebase offset or process scoped page table
+info. Examples of vCPU specific are GPRs or VSRs. A bit in the flags
+parameter specifies if this call is L2 wide or vCPU specific and the
+IDs in the GSB must match this.
+
+The L1 provides a pointer to the GSB as a parameter to this call. Also
+provided is the L2 and vCPU IDs associated with the state to set.
+
+The L1 writes only the IDs and sizes in the GSB. L0 writes the
+associated values for each ID in the GSB::
+
+ H_GUEST_GET_STATE(uint64 flags,
+ uint64 guestId,
+ uint64 vcpuId,
+ uint64 dataBuffer,
+ uint64 dataBufferSizeInBytes);
+ Parameters:
+ Input:
+ flags:
+ Bit 0: getGuestWideState: Request state of the Guest instead
+ of an individual VCPU.
+ Bit 1: getHostWideState: Request stats of the Host. This causes

+ to get the VCPU/Guest state will cause an error.
+ Bits 2-63: Reserved
+ guestId: ID obtained from H_GUEST_CREATE
+ vcpuId: ID of the vCPU pass to H_GUEST_CREATE_VCPU
+ dataBuffer: A L1 real address of the GSB.
+ If takeOwnershipOfVcpuState, size must be at least the size
+ returned by ID=0x0001
+ dataBufferSizeInBytes: Size of dataBuffer
+ Output:
+ R3: Return code
+ R4: If R3 = H_Invalid_Element_Id: The array index of the bad
+ element ID.
+ If R3 = H_Invalid_Element_Size: The array index of the bad
+ element size.
+ If R3 = H_Invalid_Element_Value: The array index of the bad
+ element value.
+
+H_GUEST_SET_STATE()
+-------------------
+
+This is called to set L2 wide or vCPU specific L2 state. This info is
+passed via the Guest State Buffer (GSB), necessary details below:
+
+This can set either L2 wide or vcpu specific information. Examples of
+L2 wide is the timebase offset or process scoped page table
+info. Examples of vCPU specific are GPRs or VSRs. A bit in the flags
+parameter specifies if this call is L2 wide or vCPU specific and the
+IDs in the GSB must match this.
+
+The L1 provides a pointer to the GSB as a parameter to this call. Also
+provided is the L2 and vCPU IDs associated with the state to set.
+
+The L1 writes all values in the GSB and the L0 only reads the GSB for
+this call::
+
+ H_GUEST_SET_STATE(uint64 flags,
+ uint64 guestId,
+ uint64 vcpuId,
+ uint64 dataBuffer,
+ uint64 dataBufferSizeInBytes);
+ Parameters:
+ Input:
+ flags:
+ Bit 0: getGuestWideState: Request state of the Guest instead
+ of an individual VCPU.
+ Bit 1: returnOwnershipOfVcpuState Return Guest VCPU state. See
+ GET_STATE takeOwnershipOfVcpuState
+ Bits 2-63: Reserved
+ guestId: ID obtained from H_GUEST_CREATE
+ vcpuId: ID of the vCPU pass to H_GUEST_CREATE_VCPU
+ dataBuffer: A L1 real address of the GSB.
+ If takeOwnershipOfVcpuState, size must be at least the size
+ returned by ID=0x0001
+ dataBufferSizeInBytes: Size of dataBuffer
+ Output:
+ R3: Return code
+ R4: If R3 = H_Invalid_Element_Id: The array index of the bad
+ element ID.
+ If R3 = H_Invalid_Element_Size: The array index of the bad
+ element size.
+ If R3 = H_Invalid_Element_Value: The array index of the bad
+ element value.
+
+H_GUEST_RUN_VCPU()
+------------------
+
+This is called to run an L2 vCPU. The L2 and vCPU IDs are passed in as
+parameters. The vCPU runs with the state set previously using
+H_GUEST_SET_STATE(). When the L2 exits, the L1 will resume from this
+hcall.
+
+This hcall also has associated input and output GSBs. Unlike
+H_GUEST_{S,G}ET_STATE(), these GSB pointers are not passed in as
+parameters to the hcall (This was done in the interest of
+performance). The locations of these GSBs must be preregistered using
+the H_GUEST_SET_STATE() call with ID 0x0c00 and 0x0c01 (see table
+below).
+
+The input GSB may contain only VCPU specific elements to be set. This
+GSB may also contain zero elements (ie 0 in the first 4 bytes of the
+GSB) if nothing needs to be set.
+
+On exit from the hcall, the output buffer is filled with elements
+determined by the L0. The reason for the exit is contained in GPR4 (ie
+NIP is put in GPR4). The elements returned depend on the exit
+type. For example, if the exit reason is the L2 doing a hcall (GPR4 =
+0xc00), then GPR3-12 are provided in the output GSB as this is the
+state likely needed to service the hcall. If additional state is
+needed, H_GUEST_GET_STATE() may be called by the L1.
+
+To synthesize interrupts in the L2, when calling H_GUEST_RUN_VCPU()
+the L1 may set a flag (as a hcall parameter) and the L0 will
+synthesize the interrupt in the L2. Alternatively, the L1 may
+synthesize the interrupt itself using H_GUEST_SET_STATE() or the
+H_GUEST_RUN_VCPU() input GSB to set the state appropriately::
+
+ H_GUEST_RUN_VCPU(uint64 flags,
+ uint64 guestId,
+ uint64 vcpuId,
+ uint64 dataBuffer,
+ uint64 dataBufferSizeInBytes);
+ Parameters:
+ Input:
+ flags:
+ Bit 0: generateExternalInterrupt: Generate an external interrupt
+ Bit 1: generatePrivilegedDoorbell: Generate a Privileged Doorbell
+ Bit 2: sendToSystemReset”: Generate a System Reset Interrupt
+ Bits 3-63: Reserved
+ guestId: ID obtained from H_GUEST_CREATE
+ vcpuId: ID of the vCPU pass to H_GUEST_CREATE_VCPU
+ Output:
+ R3: Return code
+ R4: If R3 = H_Success: The reason L1 VCPU exited (ie. NIA)
+ 0x000: The VCPU stopped running for an unspecified reason. An
+ example of this is the Hypervisor stopping a VCPU running
+ due to an outstanding interrupt for the Host Partition.
+ 0x980: HDEC
+ 0xC00: HCALL
+ 0xE00: HDSI
+ 0xE20: HISI
+ 0xE40: HEA
+ 0xF80: HV Fac Unavail
+ If R3 = H_Invalid_Element_Id, H_Invalid_Element_Size, or
+ H_Invalid_Element_Value: R4 is offset of the invalid element
+ in the input buffer.
+
+H_GUEST_DELETE()
+----------------
+
+This is called to delete an L2. All associated vCPUs are also
+deleted. No specific vCPU delete call is provided.
+
+A flag may be provided to delete all guests. This is used to reset the
+L0 in the case of kdump/kexec::
+
+ H_GUEST_DELETE(uint64 flags,
+ uint64 guestId)
+ Parameters:
+ Input:
+ flags:
+ Bit 0: deleteAllGuests: deletes all guests
+ Bits 1-63: Reserved
+ guestId: ID obtained from H_GUEST_CREATE
+ Output:
+ R3: Return code
+
+Guest State Buffer
+==================
+
+The Guest State Buffer (GSB) is the main method of communicating state
+about the L2 between the L1 and L0 via H_GUEST_{G,S}ET() and
+H_GUEST_VCPU_RUN() calls.
+
+State may be associated with a whole L2 (eg timebase offset) or a
+specific L2 vCPU (eg. GPR state). Only L2 VCPU state maybe be set by
+H_GUEST_VCPU_RUN().
+
+All data in the GSB is big endian (as is standard in PAPR)
+
+The Guest state buffer has a header which gives the number of
+elements, followed by the GSB elements themselves.
+
+GSB header:
+
++----------+----------+-------------------------------------------+
+| Offset | Size | Purpose |
+| Bytes | Bytes | |

+
+The ID in the GSB element specifies what is to be set. This includes
+archtected state like GPRs, VSRs, SPRs, plus also some meta data about
+the partition like the timebase offset and partition scoped page
+table information.

+Miscellaneous info
+==================
+
+State not in ptregs/hvregs
+--------------------------
+
+In the v1 API, some state is not in the ptregs/hvstate. This includes
+the vector register and some SPRs. For the L1 to set this state for
+the L2, the L1 loads up these hardware registers before the
+h_enter_nested() call and the L0 ensures they end up as the L2 state
+(by not touching them).
+
+The v2 API removes this and explicitly sets this state via the GSB.
+
+L1 Implementation details: Caching state
+----------------------------------------
+
+In the v1 API, all state is sent from the L1 to the L0 and vice versa
+on every h_enter_nested() hcall. If the L0 is not currently running
+any L2s, the L0 has no state information about them. The only
+exception to this is the location of the partition table, registered
+via h_set_partition_table().
+
+The v2 API changes this so that the L0 retains the L2 state even when
+it's vCPUs are no longer running. This means that the L1 only needs to
+communicate with the L0 about L2 state when it needs to modify the L2
+state, or when it's value is out of date. This provides an opportunity
+for performance optimisation.
+
+When a vCPU exits from a H_GUEST_RUN_VCPU() call, the L1 internally
+marks all L2 state as invalid. This means that if the L1 wants to know
+the L2 state (say via a kvm_get_one_reg() call), it needs call
+H_GUEST_GET_STATE() to get that state. Once it's read, it's marked as
+valid in L1 until the L2 is run again.
+
+Also, when an L1 modifies L2 vcpu state, it doesn't need to write it
+to the L0 until that L2 vcpu runs again. Hence when the L1 updates
+state (say via a kvm_set_one_reg() call), it writes to an internal L1
+copy and only flushes this copy to the L0 when the L2 runs again via
+the H_GUEST_VCPU_RUN() input buffer.
+
+This lazy updating of state by the L1 avoids unnecessary
+H_GUEST_{G|S}ET_STATE() calls.

+DTL (Dispatch Trace Log)
+===================================
+
+Athira Rajeev, 19 April 2025
+
+.. contents::
+ :depth: 3
+
+
+Basic overview
+==============
+
+The pseries Shared Processor Logical Partition(SPLPAR) machines can
+retrieve a log of dispatch and preempt events from the hypervisor
+using data from Disptach Trace Log(DTL) buffer. With this information,
+user can retrieve when and why each dispatch & preempt has occurred.
+The vpa-dtl PMU exposes the Virtual Processor Area(VPA) DTL counters
+via perf.
+
+Infrastructure used
+===================
+
+The VPA DTL PMU counters do not interrupt on overflow or generate any
+PMI interrupts. Therefore, hrtimer is used to poll the DTL data. The timer
+nterval can be provided by user via sample_period field in nano seconds.
+vpa dtl pmu has one hrtimer added per vpa-dtl pmu thread. DTL (Dispatch
+Trace Log) contains information about dispatch/preempt, enqueue time etc.
+We directly copy the DTL buffer data as part of auxiliary buffer and it
+will be processed later. This will avoid time taken to create samples
+in the kernel space. The PMU driver collecting Dispatch Trace Log (DTL)
+entries makes use of AUX support in perf infrastructure. On the tools side,
+this data is made available as PERF_RECORD_AUXTRACE records.
+
+To correlate each DTL entry with other events across CPU's, an auxtrace_queue
+is created for each CPU. Each auxtrace queue has a array/list of auxtrace buffers.
+All auxtrace queues is maintained in auxtrace heap. The queues are sorted
+based on timestamp. When the different PERF_RECORD_XX records are processed,
+compare the timestamp of perf record with timestamp of top element in the
+auxtrace heap so that DTL events can be co-related with other events
+Process the auxtrace queue if the timestamp of element from heap is
+lower than timestamp from entry in perf record. Sometimes it could happen that
+one buffer is only partially processed. if the timestamp of occurrence of
+another event is more than currently processed element in the queue, it will
+move on to next perf record. So keep track of position of buffer to continue
+processing next time. Update the timestamp of the auxtrace heap with the timestamp
+of last processed entry from the auxtrace buffer.
+
+This infrastructure ensures dispatch trace log entries can be correlated
+and presented along with other events like sched.

+.. code-block:: sh
+
+ # ./perf record -a -e sched:\*,vpa_dtl/dtl_all/ -c 1000000000 sleep 1
+
+The result can be interpreted using perf record. Snippet of perf report -D
+
+.. code-block:: sh

+ # ./perf report -D
+
+There are different PERF_RECORD_XX records. In that records corresponding to
+auxtrace buffers includes:
+
+1. PERF_RECORD_AUX
+ Conveys that new data is available in AUX area
+
+2. PERF_RECORD_AUXTRACE_INFO
+ Describes offset and size of auxtrace data in the buffers
+
+3. PERF_RECORD_AUXTRACE
+ This is the record that defines the auxtrace data which here in case of
+ vpa-dtl pmu is dispatch trace log data.

+Boot image header in RISC-V Linux
+=================================
+
+:Author: Atish Patra <atish.patra@wdc.com>
+:Date: 20 May 2019
+
+This document only describes the boot image header details for RISC-V Linux.
+
+The following 64-byte header is present in decompressed Linux kernel image::
+
+ u32 code0; /* Executable code */
+ u32 code1; /* Executable code */
+ u64 text_offset; /* Image load offset, little endian */
+ u64 image_size; /* Effective Image size, little endian */
+ u64 flags; /* kernel flags, little endian */
+ u32 version; /* Version of this header */
+ u32 res1 = 0; /* Reserved */
+ u64 res2 = 0; /* Reserved */
+ u64 magic = 0x5643534952; /* Magic number, little endian, "RISCV" */
+ u32 magic2 = 0x05435352; /* Magic number 2, little endian, "RSC\x05" */
+ u32 res3; /* Reserved for PE COFF offset */
+
+This header format is compliant with PE/COFF header and largely inspired from
+ARM64 header. Thus, both ARM64 & RISC-V header can be combined into one common
+header in future.
+
+Notes
+=====
+
+- This header is also reused to support EFI stub for RISC-V. EFI specification
+ needs PE/COFF image header in the beginning of the kernel image in order to
+ load it as an EFI application. In order to support EFI stub, code0 is replaced
+ with "MZ" magic string and res3(at offset 0x3c) points to the rest of the
+ PE/COFF header.
+
+- version field indicate header version number
+
+ ========== =============
+ Bits 0:15 Minor version
+ Bits 16:31 Major version
+ ========== =============
+
+ This preserves compatibility across newer and older version of the header.
+ The current version is defined as 0.2.
+
+- The "magic" field is deprecated as of version 0.2. In a future
+ release, it may be removed. This originally should have matched up
+ with the ARM64 header "magic" field, but unfortunately does not.
+ The "magic2" field replaces it, matching up with the ARM64 header.
+
+- In current header, the flags field has only one field.
+
+ ===== ====================================
+ Bit 0 Kernel endianness. 1 if BE, 0 if LE.
+ ===== ====================================
+
+- Image size is mandatory for boot loader to load kernel image. Booting will
+ fail otherwise.

+RISC-V Kernel Boot Requirements and Constraints
+===============================================
+
+:Author: Alexandre Ghiti <alexghiti@rivosinc.com>
+:Date: 23 May 2023
+
+This document describes what the RISC-V kernel expects from bootloaders and
+firmware, and also the constraints that any developer must have in mind when
+touching the early boot process. For the purposes of this document, the
+``early boot process`` refers to any code that runs before the final virtual
+mapping is set up.
+
+Pre-kernel Requirements and Constraints
+=======================================
+
+The RISC-V kernel expects the following of bootloaders and platform firmware:
+
+Register state
+--------------
+
+The RISC-V kernel expects:
+
+ * ``$a0`` to contain the hartid of the current core.
+ * ``$a1`` to contain the address of the devicetree in memory.
+
+CSR state
+---------
+
+The RISC-V kernel expects:
+
+ * ``$satp = 0``: the MMU, if present, must be disabled.
+
+Reserved memory for resident firmware
+-------------------------------------
+
+The RISC-V kernel must not map any resident memory, or memory protected with
+PMPs, in the direct mapping, so the firmware must correctly mark those regions
+as per the devicetree specification and/or the UEFI specification.
+
+Kernel location
+---------------
+
+The RISC-V kernel expects to be placed at a PMD boundary (2MB aligned for rv64
+and 4MB aligned for rv32). Note that the EFI stub will physically relocate the
+kernel if that's not the case.
+
+Hardware description
+--------------------
+
+The firmware can pass either a devicetree or ACPI tables to the RISC-V kernel.
+
+The devicetree is either passed directly to the kernel from the previous stage
+using the ``$a1`` register, or when booting with UEFI, it can be passed using the
+EFI configuration table.
+
+The ACPI tables are passed to the kernel using the EFI configuration table. In
+this case, a tiny devicetree is still created by the EFI stub. Please refer to
+"EFI stub and devicetree" section below for details about this devicetree.
+
+Kernel entry
+------------
+
+On SMP systems, there are 2 methods to enter the kernel:
+
+- ``RISCV_BOOT_SPINWAIT``: the firmware releases all harts in the kernel, one hart
+ wins a lottery and executes the early boot code while the other harts are
+ parked waiting for the initialization to finish. This method is mostly used to
+ support older firmwares without SBI HSM extension and M-mode RISC-V kernel.
+- ``Ordered booting``: the firmware releases only one hart that will execute the
+ initialization phase and then will start all other harts using the SBI HSM
+ extension. The ordered booting method is the preferred booting method for
+ booting the RISC-V kernel because it can support CPU hotplug and kexec.
+
+UEFI
+----
+
+UEFI memory map
+~~~~~~~~~~~~~~~
+
+When booting with UEFI, the RISC-V kernel will use only the EFI memory map to
+populate the system memory.
+
+The UEFI firmware must parse the subnodes of the ``/reserved-memory`` devicetree
+node and abide by the devicetree specification to convert the attributes of
+those subnodes (``no-map`` and ``reusable``) into their correct EFI equivalent
+(refer to section "3.5.4 /reserved-memory and UEFI" of the devicetree
+specification v0.4-rc1).
+
+RISCV_EFI_BOOT_PROTOCOL
+~~~~~~~~~~~~~~~~~~~~~~~
+
+When booting with UEFI, the EFI stub requires the boot hartid in order to pass
+it to the RISC-V kernel in ``$a1``. The EFI stub retrieves the boot hartid using
+one of the following methods:
+
+- ``RISCV_EFI_BOOT_PROTOCOL`` (**preferred**).
+- ``boot-hartid`` devicetree subnode (**deprecated**).
+
+Any new firmware must implement ``RISCV_EFI_BOOT_PROTOCOL`` as the devicetree
+based approach is deprecated now.
+
+Early Boot Requirements and Constraints
+=======================================
+
+The RISC-V kernel's early boot process operates under the following constraints:
+
+EFI stub and devicetree
+-----------------------
+
+When booting with UEFI, the devicetree is supplemented (or created) by the EFI
+stub with the same parameters as arm64 which are described at the paragraph
+"UEFI kernel support on ARM" in Documentation/arch/arm/uefi.rst.
+
+Virtual mapping installation
+----------------------------
+
+The installation of the virtual mapping is done in 2 steps in the RISC-V kernel:
+
+1. ``setup_vm()`` installs a temporary kernel mapping in ``early_pg_dir`` which
+ allows discovery of the system memory. Only the kernel text/data are mapped
+ at this point. When establishing this mapping, no allocation can be done
+ (since the system memory is not known yet), so ``early_pg_dir`` page table is
+ statically allocated (using only one table for each level).
+
+2. ``setup_vm_final()`` creates the final kernel mapping in ``swapper_pg_dir``
+ and takes advantage of the discovered system memory to create the linear
+ mapping. When establishing this mapping, the kernel can allocate memory but
+ cannot access it directly (since the direct mapping is not present yet), so
+ it uses temporary mappings in the fixmap region to be able to access the
+ newly allocated page table levels.
+
+For ``virt_to_phys()`` and ``phys_to_virt()`` to be able to correctly convert
+direct mapping addresses to physical addresses, they need to know the start of
+the DRAM. This happens after step 1, right before step 2 installs the direct
+mapping (see ``setup_bootmem()`` function in arch/riscv/mm/init.c). Any usage of
+those macros before the final virtual mapping is installed must be carefully
+examined.
+
+Devicetree mapping via fixmap
+-----------------------------
+
+As the ``reserved_mem`` array is initialized with virtual addresses established
+by ``setup_vm()``, and used with the mapping established by
+``setup_vm_final()``, the RISC-V kernel uses the fixmap region to map the
+devicetree. This ensures that the devicetree remains accessible by both virtual
+mappings.
+
+Pre-MMU execution
+-----------------
+
+A few pieces of code need to run before even the first virtual mapping is
+established. These are the installation of the first virtual mapping itself,
+patching of early alternatives and the early parsing of the kernel command line.
+That code must be very carefully compiled as:
+
+- ``-fno-pie``: This is needed for relocatable kernels which use ``-fPIE``,
+ since otherwise, any access to a global symbol would go through the GOT which
+ is only relocated virtually.
+- ``-mcmodel=medany``: Any access to a global symbol must be PC-relative to
+ avoid any relocations to happen before the MMU is setup.
+- *all* instrumentation must also be disabled (that includes KASAN, ftrace and
+ others).
+
+As using a symbol from a different compilation unit requires this unit to be
+compiled with those flags, we advise, as much as possible, not to use external
+symbols.

+==============================================================================
+Concurrent Modification and Execution of Instructions (CMODX) for RISC-V Linux
+==============================================================================
+
+CMODX is a programming technique where a program executes instructions that were
+modified by the program itself. Instruction storage and the instruction cache
+(icache) are not guaranteed to be synchronized on RISC-V hardware. Therefore, the
+program must enforce its own synchronization with the unprivileged fence.i
+instruction.
+
+CMODX in the Kernel Space
+-------------------------
+
+Dynamic ftrace
+---------------------
+
+Essentially, dynamic ftrace directs the control flow by inserting a function
+call at each patchable function entry, and patches it dynamically at runtime to
+enable or disable the redirection. In the case of RISC-V, 2 instructions,
+AUIPC + JALR, are required to compose a function call. However, it is impossible
+to patch 2 instructions and expect that a concurrent read-side executes them
+without a race condition. This series makes atmoic code patching possible in
+RISC-V ftrace. Kernel preemption makes things even worse as it allows the old
+state to persist across the patching process with stop_machine().
+
+In order to get rid of stop_machine() and run dynamic ftrace with full kernel
+preemption, we partially initialize each patchable function entry at boot-time,
+setting the first instruction to AUIPC, and the second to NOP. Now, atmoic
+patching is possible because the kernel only has to update one instruction.
+According to Ziccif, as long as an instruction is naturally aligned, the ISA
+guarantee an atomic update.
+
+By fixing down the first instruction, AUIPC, the range of the ftrace trampoline
+is limited to +-2K from the predetermined target, ftrace_caller, due to the lack
+of immediate encoding space in RISC-V. To address the issue, we introduce
+CALL_OPS, where an 8B naturally align metadata is added in front of each
+pacthable function. The metadata is resolved at the first trampoline, then the
+execution can be derect to another custom trampoline.
+
+CMODX in the User Space
+-----------------------
+
+Though fence.i is an unprivileged instruction, the default Linux ABI prohibits
+the use of fence.i in userspace applications. At any point the scheduler may
+migrate a task onto a new hart. If migration occurs after the userspace
+synchronized the icache and instruction storage with fence.i, the icache on the
+new hart will no longer be clean. This is due to the behavior of fence.i only
+affecting the hart that it is called on. Thus, the hart that the task has been
+migrated to may not have synchronized instruction storage and icache.
+
+There are two ways to solve this problem: use the riscv_flush_icache() syscall,
+or use the ``PR_RISCV_SET_ICACHE_FLUSH_CTX`` prctl() and emit fence.i in
+userspace. The syscall performs a one-off icache flushing operation. The prctl
+changes the Linux ABI to allow userspace to emit icache flushing operations.
+
+As an aside, "deferred" icache flushes can sometimes be triggered in the kernel.
+At the time of writing, this only occurs during the riscv_flush_icache() syscall
+and when the kernel uses copy_to_user_page(). These deferred flushes happen only
+when the memory map being used by a hart changes. If the prctl() context caused
+an icache flush, this deferred icache flush will be skipped as it is redundant.
+Therefore, there will be no additional flush when using the riscv_flush_icache()
+syscall inside of the prctl() context.
+
+prctl() Interface
+---------------------
+
+Call prctl() with ``PR_RISCV_SET_ICACHE_FLUSH_CTX`` as the first argument. The
+remaining arguments will be delegated to the riscv_set_icache_flush_ctx
+function detailed below.
+
+.. kernel-doc:: arch/riscv/mm/cacheflush.c
+ :identifiers: riscv_set_icache_flush_ctx
+
+Example usage:
+
+The following files are meant to be compiled and linked with each other. The
+modify_instruction() function replaces an add with 0 with an add with one,
+causing the instruction sequence in get_value() to change from returning a zero
+to returning a one.
+
+cmodx.c::
+
+ #include <stdio.h>
+ #include <sys/prctl.h>
+
+ extern int get_value();
+ extern void modify_instruction();
+
+ int main()
+ {
+ int value = get_value();
+ printf("Value before cmodx: %d\n", value);
+
+ // Call prctl before first fence.i is called inside modify_instruction
+ prctl(PR_RISCV_SET_ICACHE_FLUSH_CTX, PR_RISCV_CTX_SW_FENCEI_ON, PR_RISCV_SCOPE_PER_PROCESS);
+ modify_instruction();
+ // Call prctl after final fence.i is called in process
+ prctl(PR_RISCV_SET_ICACHE_FLUSH_CTX, PR_RISCV_CTX_SW_FENCEI_OFF, PR_RISCV_SCOPE_PER_PROCESS);
+
+ value = get_value();
+ printf("Value after cmodx: %d\n", value);
+ return 0;

+RISC-V Hardware Probing Interface
+---------------------------------
+
+The RISC-V hardware probing interface is based around a single syscall, which
+is defined in <asm/hwprobe.h>::
+
+ struct riscv_hwprobe {
+ __s64 key;
+ __u64 value;
+ };
+
+ long sys_riscv_hwprobe(struct riscv_hwprobe *pairs, size_t pair_count,
+ size_t cpusetsize, cpu_set_t *cpus,
+ unsigned int flags);
+
+The arguments are split into three groups: an array of key-value pairs, a CPU
+set, and some flags. The key-value pairs are supplied with a count. Userspace
+must prepopulate the key field for each element, and the kernel will fill in the
+value if the key is recognized. If a key is unknown to the kernel, its key field
+will be cleared to -1, and its value set to 0. The CPU set is defined by
+CPU_SET(3) with size ``cpusetsize`` bytes. For value-like keys (eg. vendor,
+arch, impl), the returned value will only be valid if all CPUs in the given set
+have the same value. Otherwise -1 will be returned. For boolean-like keys, the
+value returned will be a logical AND of the values for the specified CPUs.
+Usermode can supply NULL for ``cpus`` and 0 for ``cpusetsize`` as a shortcut for
+all online CPUs. The currently supported flags are:
+
+* :c:macro:`RISCV_HWPROBE_WHICH_CPUS`: This flag basically reverses the behavior
+ of sys_riscv_hwprobe(). Instead of populating the values of keys for a given
+ set of CPUs, the values of each key are given and the set of CPUs is reduced
+ by sys_riscv_hwprobe() to only those which match each of the key-value pairs.
+ How matching is done depends on the key type. For value-like keys, matching
+ means to be the exact same as the value. For boolean-like keys, matching
+ means the result of a logical AND of the pair's value with the CPU's value is
+ exactly the same as the pair's value. Additionally, when ``cpus`` is an empty
+ set, then it is initialized to all online CPUs which fit within it, i.e. the
+ CPU set returned is the reduction of all the online CPUs which can be
+ represented with a CPU set of size ``cpusetsize``.
+
+All other flags are reserved for future compatibility and must be zero.
+
+On success 0 is returned, on failure a negative error code is returned.
+
+The following keys are defined:
+
+* :c:macro:`RISCV_HWPROBE_KEY_MVENDORID`: Contains the value of ``mvendorid``,

+arch/riscv maintenance guidelines for developers
+================================================
+
+Overview
+--------
+The RISC-V instruction set architecture is developed in the open:
+in-progress drafts are available for all to review and to experiment
+with implementations. New module or extension drafts can change
+during the development process - sometimes in ways that are
+incompatible with previous drafts. This flexibility can present a
+challenge for RISC-V Linux maintenance. Linux maintainers disapprove
+of churn, and the Linux development process prefers well-reviewed and
+tested code over experimental code. We wish to extend these same
+principles to the RISC-V-related code that will be accepted for
+inclusion in the kernel.
+
+Patchwork
+---------
+
+RISC-V has a patchwork instance, where the status of patches can be checked:
+
+ https://patchwork.kernel.org/project/linux-riscv/list/
+
+If your patch does not appear in the default view, the RISC-V maintainers have
+likely either requested changes, or expect it to be applied to another tree.
+
+Automation runs against this patchwork instance, building/testing patches as
+they arrive. The automation applies patches against the current HEAD of the
+RISC-V `for-next` and `fixes` branches, depending on whether the patch has been
+detected as a fix. Failing those, it will use the RISC-V `master` branch.
+The exact commit to which a series has been applied will be noted on patchwork.
+Patches for which any of the checks fail are unlikely to be applied and in most
+cases will need to be resubmitted.
+
+Submit Checklist Addendum
+-------------------------
+We'll only accept patches for new modules or extensions if the
+specifications for those modules or extensions are listed as being
+unlikely to be incompatibly changed in the future. For
+specifications from the RISC-V foundation this means "Frozen" or
+"Ratified", for the UEFI forum specifications this means a published
+ECR. (Developers may, of course, maintain their own Linux kernel trees
+that contain code for any draft extensions that they wish.)
+
+Additionally, the RISC-V specification allows implementers to create
+their own custom extensions. These custom extensions aren't required
+to go through any review or ratification process by the RISC-V
+Foundation. To avoid the maintenance complexity and potential
+performance impact of adding kernel code for implementor-specific
+RISC-V extensions, we'll only consider patches for extensions that either:
+
+- Have been officially frozen or ratified by the RISC-V Foundation, or
+- Have been implemented in hardware that is widely available, per standard
+ Linux practice.
+
+(Implementers, may, of course, maintain their own Linux kernel trees containing
+code for any custom extensions that they wish.)

+RISC-V Linux User ABI
+=====================
+
+ISA string ordering in /proc/cpuinfo
+------------------------------------
+
+The canonical order of ISA extension names in the ISA string is defined in
+chapter 27 of the unprivileged specification.
+The specification uses vague wording, such as should, when it comes to ordering,
+so for our purposes the following rules apply:
+
+#. Single-letter extensions come first, in canonical order.
+ The canonical order is "IMAFDQLCBKJTPVH".
+
+#. All multi-letter extensions will be separated from other extensions by an
+ underscore.
+
+#. Additional standard extensions (starting with 'Z') will be sorted after
+ single-letter extensions and before any higher-privileged extensions.
+
+#. For additional standard extensions, the first letter following the 'Z'
+ conventionally indicates the most closely related alphabetical
+ extension category. If multiple 'Z' extensions are named, they will be
+ ordered first by category, in canonical order, as listed above, then
+ alphabetically within a category.
+
+#. Standard supervisor-level extensions (starting with 'S') will be listed
+ after standard unprivileged extensions. If multiple supervisor-level
+ extensions are listed, they will be ordered alphabetically.
+
+#. Standard machine-level extensions (starting with 'Zxm') will be listed
+ after any lower-privileged, standard extensions. If multiple machine-level
+ extensions are listed, they will be ordered alphabetically.
+
+#. Non-standard extensions (starting with 'X') will be listed after all standard
+ extensions. If multiple non-standard extensions are listed, they will be
+ ordered alphabetically.
+
+An example string following the order is::
+
+ rv64imadc_zifoo_zigoo_zafoo_sbar_scar_zxmbaz_xqux_xrux
+
+"isa" and "hart isa" lines in /proc/cpuinfo
+-------------------------------------------
+
+The "isa" line in /proc/cpuinfo describes the lowest common denominator of
+RISC-V ISA extensions recognized by the kernel and implemented on all harts. The
+"hart isa" line, in contrast, describes the set of extensions recognized by the
+kernel on the particular hart being described, even if those extensions may not
+be present on all harts in the system.
+
+In both lines, the presence of an extension guarantees only that the hardware
+has the described capability. Additional kernel support or policy changes may be
+required before an extension's capability is fully usable by userspace programs.
+Similarly, for S-mode extensions, presence in one of these lines does not
+guarantee that the kernel is taking advantage of the extension, or that the
+feature will be visible in guest VMs managed by this kernel.
+
+Inversely, the absence of an extension in these lines does not necessarily mean
+the hardware does not support that feature. The running kernel may not recognize
+the extension, or may have deliberately removed it from the listing.
+
+Misaligned accesses
+-------------------
+
+Misaligned scalar accesses are supported in userspace, but they may perform
+poorly. Misaligned vector accesses are only supported if the Zicclsm extension
+is supported.
+
+Pointer masking
+---------------
+
+Support for pointer masking in userspace (the Supm extension) is provided via
+the ``PR_SET_TAGGED_ADDR_CTRL`` and ``PR_GET_TAGGED_ADDR_CTRL`` ``prctl()``
+operations. Pointer masking is disabled by default. To enable it, userspace
+must call ``PR_SET_TAGGED_ADDR_CTRL`` with the ``PR_PMLEN`` field set to the
+number of mask/tag bits needed by the application. ``PR_PMLEN`` is interpreted
+as a lower bound; if the kernel is unable to satisfy the request, the
+``PR_SET_TAGGED_ADDR_CTRL`` operation will fail. The actual number of tag bits
+is returned in ``PR_PMLEN`` by the ``PR_GET_TAGGED_ADDR_CTRL`` operation.
+
+Additionally, when pointer masking is enabled (``PR_PMLEN`` is greater than 0),
+a tagged address ABI is supported, with the same interface and behavior as
+documented for AArch64 (Documentation/arch/arm64/tagged-address-abi.rst).

+=========================================
+Vector Extension Support for RISC-V Linux
+=========================================
+
+This document briefly outlines the interface provided to userspace by Linux in
+order to support the use of the RISC-V Vector Extension.
+
+1. prctl() Interface
+---------------------
+
+Two new prctl() calls are added to allow programs to manage the enablement
+status for the use of Vector in userspace. The intended usage guideline for
+these interfaces is to give init systems a way to modify the availability of V
+for processes running under its domain. Calling these interfaces is not
+recommended in libraries routines because libraries should not override policies
+configured from the parent process. Also, users must note that these interfaces
+are not portable to non-Linux, nor non-RISC-V environments, so it is discourage
+to use in a portable code. To get the availability of V in an ELF program,
+please read :c:macro:`COMPAT_HWCAP_ISA_V` bit of :c:macro:`ELF_HWCAP` in the
+auxiliary vector.
+
+* prctl(PR_RISCV_V_SET_CONTROL, unsigned long arg)
+
+ Sets the Vector enablement status of the calling thread, where the control
+ argument consists of two 2-bit enablement statuses and a bit for inheritance
+ mode. Other threads of the calling process are unaffected.
+
+ Enablement status is a tri-state value each occupying 2-bit of space in
+ the control argument:
+
+ * :c:macro:`PR_RISCV_V_VSTATE_CTRL_DEFAULT`: Use the system-wide default
+ enablement status on execve(). The system-wide default setting can be
+ controlled via sysctl interface (see sysctl section below).
+
+ * :c:macro:`PR_RISCV_V_VSTATE_CTRL_ON`: Allow Vector to be run for the
+ thread.
+
+ * :c:macro:`PR_RISCV_V_VSTATE_CTRL_OFF`: Disallow Vector. Executing Vector
+ instructions under such condition will trap and casuse the termination of the thread.
+
+ arg: The control argument is a 5-bit value consisting of 3 parts, and
+ accessed by 3 masks respectively.
+
+ The 3 masks, PR_RISCV_V_VSTATE_CTRL_CUR_MASK,
+ PR_RISCV_V_VSTATE_CTRL_NEXT_MASK, and PR_RISCV_V_VSTATE_CTRL_INHERIT
+ represents bit[1:0], bit[3:2], and bit[4]. bit[1:0] accounts for the
+ enablement status of current thread, and the setting at bit[3:2] takes place
+ at next execve(). bit[4] defines the inheritance mode of the setting in
+ bit[3:2].
+
+ * :c:macro:`PR_RISCV_V_VSTATE_CTRL_CUR_MASK`: bit[1:0]: Account for the
+ Vector enablement status for the calling thread. The calling thread is
+ not able to turn off Vector once it has been enabled. The prctl() call
+ fails with EPERM if the value in this mask is PR_RISCV_V_VSTATE_CTRL_OFF
+ but the current enablement status is not off. Setting
+ PR_RISCV_V_VSTATE_CTRL_DEFAULT here takes no effect but to set back
+ the original enablement status.
+
+ * :c:macro:`PR_RISCV_V_VSTATE_CTRL_NEXT_MASK`: bit[3:2]: Account for the
+ Vector enablement setting for the calling thread at the next execve()
+ system call. If PR_RISCV_V_VSTATE_CTRL_DEFAULT is used in this mask,
+ then the enablement status will be decided by the system-wide
+ enablement status when execve() happen.
+
+ * :c:macro:`PR_RISCV_V_VSTATE_CTRL_INHERIT`: bit[4]: the inheritance
+ mode for the setting at PR_RISCV_V_VSTATE_CTRL_NEXT_MASK. If the bit
+ is set then the following execve() will not clear the setting in both
+ PR_RISCV_V_VSTATE_CTRL_NEXT_MASK and PR_RISCV_V_VSTATE_CTRL_INHERIT.
+ This setting persists across changes in the system-wide default value.
+
+ Return value:
+ * 0 on success;
+ * EINVAL: Vector not supported, invalid enablement status for current or
+ next mask;
+ * EPERM: Turning off Vector in PR_RISCV_V_VSTATE_CTRL_CUR_MASK if Vector
+ was enabled for the calling thread.
+
+ On success:
+ * A valid setting for PR_RISCV_V_VSTATE_CTRL_CUR_MASK takes place
+ immediately. The enablement status specified in
+ PR_RISCV_V_VSTATE_CTRL_NEXT_MASK happens at the next execve() call, or
+ all following execve() calls if PR_RISCV_V_VSTATE_CTRL_INHERIT bit is
+ set.
+ * Every successful call overwrites a previous setting for the calling
+ thread.
+
+* prctl(PR_RISCV_V_GET_CONTROL)
+
+ Gets the same Vector enablement status for the calling thread. Setting for
+ next execve() call and the inheritance bit are all OR-ed together.
+
+ Note that ELF programs are able to get the availability of V for itself by
+ reading :c:macro:`COMPAT_HWCAP_ISA_V` bit of :c:macro:`ELF_HWCAP` in the
+ auxiliary vector.
+
+ Return value:
+ * a nonnegative value on success;
+ * EINVAL: Vector not supported.
+
+2. System runtime configuration (sysctl)
+-----------------------------------------
+
+To mitigate the ABI impact of expansion of the signal stack, a
+policy mechanism is provided to the administrators, distro maintainers, and
+developers to control the default Vector enablement status for userspace
+processes in form of sysctl knob:
+
+* /proc/sys/abi/riscv_v_default_allow
+
+ Writing the text representation of 0 or 1 to this file sets the default
+ system enablement status for new starting userspace programs. Valid values
+ are:
+
+ * 0: Do not allow Vector code to be executed as the default for new processes.
+ * 1: Allow Vector code to be executed as the default for new processes.
+
+ Reading this file returns the current system default enablement status.
+
+ At every execve() call, a new enablement status of the new process is set to
+ the system default, unless:
+
+ * PR_RISCV_V_VSTATE_CTRL_INHERIT is set for the calling process, and the
+ setting in PR_RISCV_V_VSTATE_CTRL_NEXT_MASK is not
+ PR_RISCV_V_VSTATE_CTRL_DEFAULT. Or,
+
+ * The setting in PR_RISCV_V_VSTATE_CTRL_NEXT_MASK is not
+ PR_RISCV_V_VSTATE_CTRL_DEFAULT.
+
+ Modifying the system default enablement status does not affect the enablement
+ status of any existing process of thread that do not make an execve() call.
+
+3. Vector Register State Across System Calls
+---------------------------------------------
+
+As indicated by version 1.0 of the V extension [1], vector registers are
+clobbered by system calls.

+Debugging AMD Zen systems
++++++++++++++++++++++++++
+
+Introduction
+============
+
+This document describes techniques that are useful for debugging issues with
+AMD Zen systems. It is intended for use by developers and technical users
+to help identify and resolve issues.
+
+S3 vs s2idle
+============
+
+On AMD systems, it's not possible to simultaneously support suspend-to-RAM (S3)
+and suspend-to-idle (s2idle). To confirm which mode your system supports you
+can look at ``cat /sys/power/mem_sleep``. If it shows ``s2idle [deep]`` then
+*S3* is supported. If it shows ``[s2idle]`` then *s2idle* is
+supported.
+
+On systems that support *S3*, the firmware will be utilized to put all hardware into
+the appropriate low power state.
+
+On systems that support *s2idle*, the kernel will be responsible for transitioning devices
+into the appropriate low power state. When all devices are in the appropriate low
+power state, the hardware will transition into a hardware sleep state.
+
+After a suspend cycle you can tell how much time was spent in a hardware sleep
+state by looking at ``cat /sys/power/suspend_stats/last_hw_sleep``.
+
+This flowchart explains how the AMD s2idle suspend flow works.
+
+.. kernel-figure:: suspend.svg
+
+This flowchart explains how the amd s2idle resume flow works.
+
+.. kernel-figure:: resume.svg
+
+s2idle debugging tool
+=====================
+
+As there are a lot of places that problems can occur, a debugging tool has been
+created at
+`amd-debug-tools <https://git.kernel.org/pub/scm/linux/kernel/git/superm1/amd-debug-tools.git/about/>`_
+that can help test for common problems and offer suggestions.
+
+If you have an s2idle issue, it's best to start with this and follow instructions
+from its findings. If you continue to have an issue, raise a bug with the
+report generated from this script to
+`drm/amd gitlab <https://gitlab.freedesktop.org/drm/amd/-/issues/new?issuable_template=s2idle_BUG_TEMPLATE>`_.
+
+Spurious s2idle wakeups from an IRQ
+===================================
+
+Spurious wakeups will generally have an IRQ set to ``/sys/power/pm_wakeup_irq``.
+This can be matched to ``/proc/interrupts`` to determine what device woke the system.
+
+If this isn't enough to debug the problem, then the following sysfs files
+can be set to add more verbosity to the wakeup process: ::
+
+ # echo 1 | sudo tee /sys/power/pm_debug_messages
+ # echo 1 | sudo tee /sys/power/pm_print_times
+
+After making those changes, the kernel will display messages that can
+be traced back to kernel s2idle loop code as well as display any active
+GPIO sources while waking up.
+
+If the wakeup is caused by the ACPI SCI, additional ACPI debugging may be
+needed. These commands can enable additional trace data: ::
+
+ # echo enable | sudo tee /sys/module/acpi/parameters/trace_state
+ # echo 1 | sudo tee /sys/module/acpi/parameters/aml_debug_output
+ # echo 0x0800000f | sudo tee /sys/module/acpi/parameters/debug_level
+ # echo 0xffff0000 | sudo tee /sys/module/acpi/parameters/debug_layer
+
+Spurious s2idle wakeups from a GPIO
+===================================
+
+If a GPIO is active when waking up the system ideally you would look at the
+schematic to determine what device it is associated with. If the schematic
+is not available, another tactic is to look at the ACPI _EVT() entry
+to determine what device is notified when that GPIO is active.
+
+For a hypothetical example, say that GPIO 59 woke up the system. You can
+look at the SSDT to determine what device is notified when GPIO 59 is active.
+
+First convert the GPIO number into hex. ::
+
+ $ python3 -c "print(hex(59))"
+ 0x3b
+
+Next determine which ACPI table has the ``_EVT`` entry. For example: ::
+
+ $ sudo grep EVT /sys/firmware/acpi/tables/SSDT*
+ grep: /sys/firmware/acpi/tables/SSDT27: binary file matches
+
+Decode this table::
+
+ $ sudo cp /sys/firmware/acpi/tables/SSDT27 .
+ $ sudo iasl -d SSDT27
+
+Then look at the table and find the matching entry for GPIO 0x3b. ::
+
+ Case (0x3B)
+ {
+ M000 (0x393B)
+ M460 (" Notify (\\_SB.PCI0.GP17.XHC1, 0x02)\n", Zero, Zero, Zero, Zero, Zero, Zero)
+ Notify (\_SB.PCI0.GP17.XHC1, 0x02) // Device Wake
+ }
+
+You can see in this case that the device ``\_SB.PCI0.GP17.XHC1`` is notified
+when GPIO 59 is active. It's obvious this is an XHCI controller, but to go a
+step further you can figure out which XHCI controller it is by matching it to
+ACPI.::
+
+ $ grep "PCI0.GP17.XHC1" /sys/bus/acpi/devices/*/path
+ /sys/bus/acpi/devices/device:2d/path:\_SB_.PCI0.GP17.XHC1
+ /sys/bus/acpi/devices/device:2e/path:\_SB_.PCI0.GP17.XHC1.RHUB
+ /sys/bus/acpi/devices/device:2f/path:\_SB_.PCI0.GP17.XHC1.RHUB.PRT1
+ /sys/bus/acpi/devices/device:30/path:\_SB_.PCI0.GP17.XHC1.RHUB.PRT1.CAM0
+ /sys/bus/acpi/devices/device:31/path:\_SB_.PCI0.GP17.XHC1.RHUB.PRT1.CAM1
+ /sys/bus/acpi/devices/device:32/path:\_SB_.PCI0.GP17.XHC1.RHUB.PRT2
+ /sys/bus/acpi/devices/LNXPOWER:0d/path:\_SB_.PCI0.GP17.XHC1.PWRS
+
+Here you can see it matches to ``device:2d``. Look at the ``physical_node``
+to determine what PCI device that actually is. ::
+
+ $ ls -l /sys/bus/acpi/devices/device:2d/physical_node
+ lrwxrwxrwx 1 root root 0 Feb 12 13:22 /sys/bus/acpi/devices/device:2d/physical_node -> ../../../../../pci0000:00/0000:00:08.1/0000:c2:00.4
+
+So there you have it: the PCI device associated with this GPIO wakeup was ``0000:c2:00.4``.
+
+The ``amd_s2idle.py`` script will capture most of these artifacts for you.
+
+s2idle PM debug messages
+========================
+
+During the s2idle flow on AMD systems, the ACPI LPS0 driver is responsible
+to check all uPEP constraints. Failing uPEP constraints does not prevent
+s0i3 entry. This means that if some constraints are not met, it is possible
+the kernel may attempt to enter s2idle even if there are some known issues.
+
+To activate PM debugging, either specify ``pm_debug_messagess`` kernel
+command-line option at boot or write to ``/sys/power/pm_debug_messages``.
+Unmet constraints will be displayed in the kernel log and can be
+viewed by logging tools that process kernel ring buffer like ``dmesg`` or
+``journalctl``."
+
+If the system freezes on entry/exit before these messages are flushed, a
+useful debugging tactic is to unbind the ``amd_pmc`` driver to prevent
+notification to the platform to start s0i3 entry. This will stop the
+system from freezing on entry or exit and let you view all the failed
+constraints. ::
+
+ cd /sys/bus/platform/drivers/amd_pmc
+ ls | grep AMD | sudo tee unbind
+
+After doing this, run the suspend cycle and look specifically for errors around: ::
+
+ ACPI: LPI: Constraint not met; min power state:%s current power state:%s
+
+Historical examples of s2idle issues
+====================================
+
+To help understand the types of issues that can occur and how to debug them,
+here are some historical examples of s2idle issues that have been resolved.
+
+Core offlining
+--------------
+An end user had reported that taking a core offline would prevent the system
+from properly entering s0i3. This was debugged using internal AMD tools
+to capture and display a stream of metrics from the hardware showing what changed
+when a core was offlined. It was determined that the hardware didn't get
+notification the offline cores were in the deepest state, and so it prevented
+CPU from going into the deepest state. The issue was debugged to a missing
+command to put cores into C3 upon offline.
+
+`commit d6b88ce2eb9d2 ("ACPI: processor idle: Allow playing dead in C3 state") <https://git.kernel.org/torvalds/c/d6b88ce2eb9d2>`_
+
+Corruption after resume
+-----------------------
+A big problem that occurred with Rembrandt was that there was graphical
+corruption after resume. This happened because of a misalignment of PSP
+and driver responsibility. The PSP will save and restore DMCUB, but the
+driver assumed it needed to reset DMCUB on resume.
+This actually was a misalignment for earlier silicon as well, but was not
+observed.
+
+`commit 79d6b9351f086 ("drm/amd/display: Don't reinitialize DMCUB on s0ix resume") <https://git.kernel.org/torvalds/c/79d6b9351f086>`_
+
+Back to Back suspends fail
+--------------------------
+When using a wakeup source that triggers the IRQ to wakeup, a bug in the
+pinctrl-amd driver may capture the wrong state of the IRQ and prevent the
+system going back to sleep properly.
+
+`commit b8c824a869f22 ("pinctrl: amd: Don't save/restore interrupt status and wake status bits") <https://git.kernel.org/torvalds/c/b8c824a869f22>`_
+
+Spurious timer based wakeup after 5 minutes
+-------------------------------------------
+The HPET was being used to program the wakeup source for the system, however
+this was causing a spurious wakeup after 5 minutes. The correct alarm to use
+was the ACPI alarm.
+
+`commit 3d762e21d5637 ("rtc: cmos: Use ACPI alarm for non-Intel x86 systems too") <https://git.kernel.org/torvalds/c/3d762e21d5637>`_
+
+Disk disappears after resume
+----------------------------
+After resuming from s2idle, the NVME disk would disappear. This was due to the
+BIOS not specifying the _DSD StorageD3Enable property. This caused the NVME
+driver not to put the disk into the expected state at suspend and to fail
+on resume.
+
+`commit e79a10652bbd3 ("ACPI: x86: Force StorageD3Enable on more products") <https://git.kernel.org/torvalds/c/e79a10652bbd3>`_
+
+Spurious IRQ1
+-------------
+A number of Renoir, Lucienne, Cezanne, & Barcelo platforms have a
+platform firmware bug where IRQ1 is triggered during s0i3 resume.
+
+This was fixed in the platform firmware, but a number of systems didn't
+receive any more platform firmware updates.
+
+`commit 8e60615e89321 ("platform/x86/amd: pmc: Disable IRQ1 wakeup for RN/CZN") <https://git.kernel.org/torvalds/c/8e60615e89321>`_
+
+Hardware timeout
+----------------
+The hardware performs many actions besides accepting the values from
+amd-pmc driver. As the communication path with the hardware is a mailbox,
+it's possible that it might not respond quickly enough.
+This issue manifested as a failure to suspend: ::
+
+ PM: dpm_run_callback(): acpi_subsys_suspend_noirq+0x0/0x50 returns -110
+ amd_pmc AMDI0005:00: PM: failed to suspend noirq: error -110
+
+The timing problem was identified by comparing the values of the idle mask.
+
+`commit 3c3c8e88c8712 ("platform/x86: amd-pmc: Increase the response register timeout") <https://git.kernel.org/torvalds/c/3c3c8e88c8712>`_
+
+Failed to reach hardware sleep state with panel on
+--------------------------------------------------
+On some Strix systems certain panels were observed to block the system from
+entering a hardware sleep state if the internal panel was on during the sequence.
+
+Even though the panel got turned off during suspend it exposed a timing problem
+where an interrupt caused the display hardware to wake up and block low power
+state entry.
+
+`commit 40b8c14936bd2 ("drm/amd/display: Disable unneeded hpd interrupts during dm_init") <https://git.kernel.org/torvalds/c/40b8c14936bd2>`_
+
+Runtime power consumption issues
+================================
+
+Runtime power consumption is influenced by many factors, including but not
+limited to the configuration of the PCIe Active State Power Management (ASPM),
+the display brightness, the EPP policy of the CPU, and the power management
+of the devices.
+
+ASPM
+----
+For the best runtime power consumption, ASPM should be programmed as intended
+by the BIOS from the hardware vendor. To accomplish this the Linux kernel
+should be compiled with ``CONFIG_PCIEASPM_DEFAULT`` set to ``y`` and the
+sysfs file ``/sys/module/pcie_aspm/parameters/policy`` should not be modified.
+
+Most notably, if L1.2 is not configured properly for any devices, the SoC
+will not be able to enter the deepest idle state.
+
+EPP Policy
+----------
+The ``energy_performance_preference`` sysfs file can be used to set a bias
+of efficiency or performance for a CPU. This has a direct relationship on
+the battery life when more heavily biased towards performance.
+
+
+BIOS debug messages
+===================
+
+Most OEM machines don't have a serial UART for outputting kernel or BIOS
+debug messages. However BIOS debug messages are useful for understanding
+both BIOS bugs and bugs with the Linux kernel drivers that call BIOS AML.
+
+As the BIOS on most OEM AMD systems are based off an AMD reference BIOS,
+the infrastructure used for exporting debugging messages is often the same
+as AMD reference BIOS.
+
+Manually Parsing
+----------------
+There is generally an ACPI method ``\M460`` that different paths of the AML
+will call to emit a message to the BIOS serial log. This method takes
+7 arguments, with the first being a string and the rest being optional
+integers::
+
+ Method (M460, 7, Serialized)
+
+Here is an example of a string that BIOS AML may call out using ``\M460``::
+
+ M460 (" OEM-ASL-PCIe Address (0x%X)._REG (%d %d) PCSA = %d\n", DADR, Arg0, Arg1, PCSA, Zero, Zero)
+
+Normally when executed, the ``\M460`` method would populate the additional
+arguments into the string. In order to get these messages from the Linux
+kernel a hook has been added into ACPICA that can capture the *arguments*
+sent to ``\M460`` and print them to the kernel ring buffer.
+For example the following message could be emitted into kernel ring buffer::
+
+ extrace-0174 ex_trace_args : " OEM-ASL-PCIe Address (0x%X)._REG (%d %d) PCSA = %d\n", ec106000, 2, 1, 1, 0, 0
+
+In order to get these messages, you need to compile with ``CONFIG_ACPI_DEBUG``
+and then turn on the following ACPICA tracing parameters.
+This can be done either on the kernel command line or at runtime:
+
+* ``acpi.trace_method_name=\M460``
+* ``acpi.trace_state=method``
+
+NOTE: These can be very noisy at bootup. If you turn these parameters on
+the kernel command, please also consider turning up ``CONFIG_LOG_BUF_SHIFT``
+to a larger size such as 17 to avoid losing early boot messages.
+
+Tool assisted Parsing
+---------------------
+As mentioned above, parsing by hand can be tedious, especially with a lot of
+messages. To help with this, a tool has been created at
+`amd-debug-tools <https://git.kernel.org/pub/scm/linux/kernel/git/superm1/amd-debug-tools.git/about/>`_
+to help parse the messages.
+
+Random reboot issues
+====================
+
+When a random reboot occurs, the high-level reason for the reboot is stored
+in a register that will persist onto the next boot.
+
+There are 6 classes of reasons for the reboot:
+ * Software induced
+ * Power state transition
+ * Pin induced
+ * Hardware induced
+ * Remote reset
+ * Internal CPU event
+
+.. csv-table::
+ :header: "Bit", "Type", "Reason"
+ :align: left
+
+ "0", "Pin", "thermal pin BP_THERMTRIP_L was tripped"
+ "1", "Pin", "power button was pressed for 4 seconds"
+ "2", "Pin", "shutdown pin was tripped"
+ "4", "Remote", "remote ASF power off command was received"
+ "9", "Internal", "internal CPU thermal limit was tripped"
+ "16", "Pin", "system reset pin BP_SYS_RST_L was tripped"

+ "20", "Software", "software wrote 0xE to reset control register 0xCF9"
+ "21", "ACPI-state", "ACPI power state transition occurred"
+ "22", "Pin", "keyboard reset pin KB_RST_L was tripped"
+ "23", "Internal", "internal CPU shutdown event occurred"
+ "24", "Hardware", "system failed to boot before failed boot timer expired"
+ "25", "Hardware", "hardware watchdog timer expired"
+ "26", "Remote", "remote ASF reset command was received"
+ "27", "Internal", "an uncorrected error caused a data fabric sync flood event"
+ "29", "Internal", "FCH and MP1 failed warm reset handshake"
+ "30", "Internal", "a parity error occurred"
+ "31", "Internal", "a software sync flood event occurred"
+
+This information is read by the kernel at bootup and printed into
+the syslog. When a random reboot occurs this message can be helpful
+to determine the next component to debug.

+Hardware Feedback Interface For Hetero Core Scheduling On AMD Platform

+
+Overview
+--------
+
+AMD Heterogeneous Core implementations are comprised of more than one
+architectural class and CPUs are comprised of cores of various efficiency and
+power capabilities: performance-oriented *classic cores* and power-efficient
+*dense cores*. As such, power management strategies must be designed to
+accommodate the complexities introduced by incorporating different core types.
+Heterogeneous systems can also extend to more than two architectural classes
+as well. The purpose of the scheduling feedback mechanism is to provide
+information to the operating system scheduler in real time such that the
+scheduler can direct threads to the optimal core.
+
+The goal of AMD's heterogeneous architecture is to attain power benefit by
+sending background threads to the dense cores while sending high priority
+threads to the classic cores. From a performance perspective, sending
+background threads to dense cores can free up power headroom and allow the
+classic cores to optimally service demanding threads. Furthermore, the area
+optimized nature of the dense cores allows for an increasing number of
+physical cores. This improved core density will have positive multithreaded
+performance impact.
+
+AMD Heterogeneous Core Driver
+-----------------------------
+
+The ``amd_hfi`` driver delivers the operating system a performance and energy
+efficiency capability data for each CPU in the system. The scheduler can use
+the ranking data from the HFI driver to make task placement decisions.
+
+Thread Classification and Ranking Table Interaction
+----------------------------------------------------
+
+The thread classification is used to select into a ranking table that
+describes an efficiency and performance ranking for each classification.
+
+Threads are classified during runtime into enumerated classes. The classes
+represent thread performance/power characteristics that may benefit from
+special scheduling behaviors. The below table depicts an example of thread
+classification and a preference where a given thread should be scheduled
+based on its thread class. The real time thread classification is consumed
+by the operating system and is used to inform the scheduler of where the
+thread should be placed.
+
+Thread Classification Example Table
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
++----------+----------------+-------------------------------+---------------------+---------+
+| class ID | Classification | Preferred scheduling behavior | Preemption priority | Counter |
++----------+----------------+-------------------------------+---------------------+---------+
+| 0 | Default | Performant | Highest | |
++----------+----------------+-------------------------------+---------------------+---------+
+| 1 | Non-scalable | Efficient | Lowest | PMCx1A1 |
++----------+----------------+-------------------------------+---------------------+---------+
+| 2 | I/O bound | Efficient | Lowest | PMCx044 |
++----------+----------------+-------------------------------+---------------------+---------+
+
+Thread classification is performed by the hardware each time that the thread is switched out.
+Threads that don't meet any hardware specified criteria are classified as "default".
+
+AMD Hardware Feedback Interface
+--------------------------------
+
+The Hardware Feedback Interface provides to the operating system information
+about the performance and energy efficiency of each CPU in the system. Each
+capability is given as a unit-less quantity in the range [0-255]. A higher
+performance value indicates higher performance capability, and a higher
+efficiency value indicates more efficiency. Energy efficiency and performance
+are reported in separate capabilities in the shared memory based ranking table.
+
+These capabilities may change at runtime as a result of changes in the
+operating conditions of the system or the action of external factors.
+Power Management firmware is responsible for detecting events that require
+a reordering of the performance and efficiency ranking. Table updates happen
+relatively infrequently and occur on the time scale of seconds or more.
+
+The following events trigger a table update:
+ * Thermal Stress Events
+ * Silent Compute
+ * Extreme Low Battery Scenarios
+
+The kernel or a userspace policy daemon can use these capabilities to modify
+task placement decisions. For instance, if either the performance or energy
+capabilities of a given logical processor becomes zero, it is an indication
+that the hardware recommends to the operating system to not schedule any tasks
+on that processor for performance or energy efficiency reasons, respectively.
+
+Implementation details for Linux
+--------------------------------
+
+The implementation of threads scheduling consists of the following steps:
+
+1. A thread is spawned and scheduled to the ideal core using the default
+ heterogeneous scheduling policy.
+2. The processor profiles thread execution and assigns an enumerated
+ classification ID.
+ This classification is communicated to the OS via logical processor
+ scope MSR.
+3. During the thread context switch out the operating system consumes the
+ workload (WL) classification which resides in a logical processor scope MSR.
+4. The OS triggers the hardware to clear its history by writing to an MSR,
+ after consuming the WL classification and before switching in the new thread.
+5. If due to the classification, ranking table, and processor availability,
+ the thread is not on its ideal processor, the OS will then consider
+ scheduling the thread on its ideal processor (if available).
+
+Ranking Table
+-------------
+The ranking table is a shared memory region that is used to communicate the
+performance and energy efficiency capabilities of each CPU in the system.
+
+The ranking table design includes rankings for each APIC ID in the system and
+rankings both for performance and efficiency for each workload classification.
+
+.. kernel-doc:: drivers/platform/x86/amd/hfi/hfi.c
+ :doc: amd_shmem_info
+
+Ranking Table update
+---------------------------
+The power management firmware issues an platform interrupt after updating the
+ranking table and is ready for the operating system to consume it. CPUs receive
+such interrupt and read new ranking table from shared memory which PCCT table
+has provided, then ``amd_hfi`` driver parses the new table to provide new
+consume data for scheduling decisions.

+=====================
+AMD Memory Encryption
+=====================
+
+Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV) are
+features found on AMD processors.
+
+SME provides the ability to mark individual pages of memory as encrypted using
+the standard x86 page tables. A page that is marked encrypted will be
+automatically decrypted when read from DRAM and encrypted when written to
+DRAM. SME can therefore be used to protect the contents of DRAM from physical
+attacks on the system.
+
+SEV enables running encrypted virtual machines (VMs) in which the code and data
+of the guest VM are secured so that a decrypted version is available only
+within the VM itself. SEV guest VMs have the concept of private and shared
+memory. Private memory is encrypted with the guest-specific key, while shared
+memory may be encrypted with hypervisor key. When SME is enabled, the hypervisor
+key is the same key which is used in SME.
+
+A page is encrypted when a page table entry has the encryption bit set (see
+below on how to determine its position). The encryption bit can also be
+specified in the cr3 register, allowing the PGD table to be encrypted. Each
+successive level of page tables can also be encrypted by setting the encryption
+bit in the page table entry that points to the next table. This allows the full
+page table hierarchy to be encrypted. Note, this means that just because the
+encryption bit is set in cr3, doesn't imply the full hierarchy is encrypted.
+Each page table entry in the hierarchy needs to have the encryption bit set to
+achieve that. So, theoretically, you could have the encryption bit set in cr3
+so that the PGD is encrypted, but not set the encryption bit in the PGD entry
+for a PUD which results in the PUD pointed to by that entry to not be
+encrypted.
+
+When SEV is enabled, instruction pages and guest page tables are always treated
+as private. All the DMA operations inside the guest must be performed on shared
+memory. Since the memory encryption bit is controlled by the guest OS when it
+is operating in 64-bit or 32-bit PAE mode, in all other modes the SEV hardware
+forces the memory encryption bit to 1.
+
+Support for SME and SEV can be determined through the CPUID instruction. The
+CPUID function 0x8000001f reports information related to SME::
+
+ 0x8000001f[eax]:
+ Bit[0] indicates support for SME
+ Bit[1] indicates support for SEV
+ 0x8000001f[ebx]:
+ Bits[5:0] pagetable bit number used to activate memory
+ encryption
+ Bits[11:6] reduction in physical address space, in bits, when
+ memory encryption is enabled (this only affects
+ system physical addresses, not guest physical
+ addresses)
+
+If support for SME is present, MSR 0xc00100010 (MSR_AMD64_SYSCFG) can be used to
+determine if SME is enabled and/or to enable memory encryption::
+
+ 0xc0010010:
+ Bit[23] 0 = memory encryption features are disabled
+ 1 = memory encryption features are enabled
+
+If SEV is supported, MSR 0xc0010131 (MSR_AMD64_SEV) can be used to determine if
+SEV is active::
+
+ 0xc0010131:
+ Bit[0] 0 = memory encryption is not active
+ 1 = memory encryption is active
+
+Linux relies on BIOS to set this bit if BIOS has determined that the reduction
+in the physical address space as a result of enabling memory encryption (see
+CPUID information above) will not conflict with the address space resource
+requirements for the system. If this bit is not set upon Linux startup then
+Linux itself will not set it and memory encryption will not be possible.
+
+The state of SME in the Linux kernel can be documented as follows:
+
+ - Supported:
+ The CPU supports SME (determined through CPUID instruction).
+
+ - Enabled:
+ Supported and bit 23 of MSR_AMD64_SYSCFG is set.
+
+ - Active:
+ Supported, Enabled and the Linux kernel is actively applying
+ the encryption bit to page table entries (the SME mask in the
+ kernel is non-zero).
+
+SME can also be enabled and activated in the BIOS. If SME is enabled and
+activated in the BIOS, then all memory accesses will be encrypted and it
+will not be necessary to activate the Linux memory encryption support.
+
+If the BIOS merely enables SME (sets bit 23 of the MSR_AMD64_SYSCFG),
+then memory encryption can be enabled by supplying mem_encrypt=on on the
+kernel command line. However, if BIOS does not enable SME, then Linux
+will not be able to activate memory encryption, even if configured to do
+so by default or the mem_encrypt=on command line parameter is specified.
+
+Secure Nested Paging (SNP)
+==========================
+
+SEV-SNP introduces new features (SEV_FEATURES[1:63]) which can be enabled
+by the hypervisor for security enhancements. Some of these features need
+guest side implementation to function correctly. The below table lists the
+expected guest behavior with various possible scenarios of guest/hypervisor
+SNP feature support.
+

+
+Reverse Map Table (RMP)
+=======================
+
+The RMP is a structure in system memory that is used to ensure a one-to-one
+mapping between system physical addresses and guest physical addresses. Each
+page of memory that is potentially assignable to guests has one entry within
+the RMP.
+
+The RMP table can be either contiguous in memory or a collection of segments
+in memory.
+
+Contiguous RMP
+--------------
+
+Support for this form of the RMP is present when support for SEV-SNP is
+present, which can be determined using the CPUID instruction::
+
+ 0x8000001f[eax]:
+ Bit[4] indicates support for SEV-SNP
+
+The location of the RMP is identified to the hardware through two MSRs::
+
+ 0xc0010132 (RMP_BASE):
+ System physical address of the first byte of the RMP
+
+ 0xc0010133 (RMP_END):
+ System physical address of the last byte of the RMP
+
+Hardware requires that RMP_BASE and (RPM_END + 1) be 8KB aligned, but SEV
+firmware increases the alignment requirement to require a 1MB alignment.
+
+The RMP consists of a 16KB region used for processor bookkeeping followed
+by the RMP entries, which are 16 bytes in size. The size of the RMP
+determines the range of physical memory that the hypervisor can assign to
+SEV-SNP guests. The RMP covers the system physical address from::
+
+ 0 to ((RMP_END + 1 - RMP_BASE - 16KB) / 16B) x 4KB.
+
+The current Linux support relies on BIOS to allocate/reserve the memory for
+the RMP and to set RMP_BASE and RMP_END appropriately. Linux uses the MSR
+values to locate the RMP and determine the size of the RMP. The RMP must
+cover all of system memory in order for Linux to enable SEV-SNP.
+
+Segmented RMP
+-------------
+
+Segmented RMP support is a new way of representing the layout of an RMP.
+Initial RMP support required the RMP table to be contiguous in memory.
+RMP accesses from a NUMA node on which the RMP doesn't reside
+can take longer than accesses from a NUMA node on which the RMP resides.
+Segmented RMP support allows the RMP entries to be located on the same
+node as the memory the RMP is covering, potentially reducing latency
+associated with accessing an RMP entry associated with the memory. Each
+RMP segment covers a specific range of system physical addresses.
+
+Support for this form of the RMP can be determined using the CPUID
+instruction::
+
+ 0x8000001f[eax]:
+ Bit[23] indicates support for segmented RMP
+
+If supported, segmented RMP attributes can be found using the CPUID
+instruction::
+
+ 0x80000025[eax]:
+ Bits[5:0] minimum supported RMP segment size
+ Bits[11:6] maximum supported RMP segment size
+
+ 0x80000025[ebx]:
+ Bits[9:0] number of cacheable RMP segment definitions
+ Bit[10] indicates if the number of cacheable RMP segments
+ is a hard limit
+
+To enable a segmented RMP, a new MSR is available::
+
+ 0xc0010136 (RMP_CFG):
+ Bit[0] indicates if segmented RMP is enabled
+ Bits[13:8] contains the size of memory covered by an RMP
+ segment (expressed as a power of 2)
+
+The RMP segment size defined in the RMP_CFG MSR applies to all segments
+of the RMP. Therefore each RMP segment covers a specific range of system
+physical addresses. For example, if the RMP_CFG MSR value is 0x2401, then
+the RMP segment coverage value is 0x24 => 36, meaning the size of memory
+covered by an RMP segment is 64GB (1 << 36). So the first RMP segment
+covers physical addresses from 0 to 0xF_FFFF_FFFF, the second RMP segment
+covers physical addresses from 0x10_0000_0000 to 0x1F_FFFF_FFFF, etc.
+
+When a segmented RMP is enabled, RMP_BASE points to the RMP bookkeeping
+area as it does today (16K in size). However, instead of RMP entries
+beginning immediately after the bookkeeping area, there is a 4K RMP
+segment table (RST). Each entry in the RST is 8-bytes in size and represents
+an RMP segment::
+
+ Bits[19:0] mapped size (in GB)
+ The mapped size can be less than the defined segment size.
+ A value of zero, indicates that no RMP exists for the range
+ of system physical addresses associated with this segment.
+ Bits[51:20] segment physical address
+ This address is left shift 20-bits (or just masked when
+ read) to form the physical address of the segment (1MB
+ alignment).
+
+The RST can hold 512 segment entries but can be limited in size to the number
+of cacheable RMP segments (CPUID 0x80000025_EBX[9:0]) if the number of cacheable
+RMP segments is a hard limit (CPUID 0x80000025_EBX[10]).
+
+The current Linux support relies on BIOS to allocate/reserve the memory for
+the segmented RMP (the bookkeeping area, RST, and all segments), build the RST
+and to set RMP_BASE, RMP_END, and RMP_CFG appropriately. Linux uses the MSR
+values to locate the RMP and determine the size and location of the RMP
+segments. The RMP must cover all of system memory in order for Linux to enable
+SEV-SNP.

+
+Secure VM Service Module (SVSM)
+===============================
+
+SNP provides a feature called Virtual Machine Privilege Levels (VMPL) which
+defines four privilege levels at which guest software can run. The most
+privileged level is 0 and numerically higher numbers have lesser privileges.
+More details in the AMD64 APM Vol 2, section "15.35.7 Virtual Machine
+Privilege Levels", docID: 24593.
+
+When using that feature, different services can run at different protection
+levels, apart from the guest OS but still within the secure SNP environment.
+They can provide services to the guest, like a vTPM, for example.
+
+When a guest is not running at VMPL0, it needs to communicate with the software
+running at VMPL0 to perform privileged operations or to interact with secure
+services. An example fur such a privileged operation is PVALIDATE which is
+*required* to be executed at VMPL0.
+
+In this scenario, the software running at VMPL0 is usually called a Secure VM
+Service Module (SVSM). Discovery of an SVSM and the API used to communicate
+with it is documented in "Secure VM Service Module for SEV-SNP Guests", docID:
+58019.
+

+a search engine like duckduckgo.com and typing in:

+============================================
+AMD HSMP interface
+============================================
+
+Newer Fam19h(model 0x00-0x1f, 0x30-0x3f, 0x90-0x9f, 0xa0-0xaf),
+Fam1Ah(model 0x00-0x1f) EPYC server line of processors from AMD support
+system management functionality via HSMP (Host System Management Port).
+
+The Host System Management Port (HSMP) is an interface to provide
+OS-level software with access to system management functions via a
+set of mailbox registers.
+
+More details on the interface can be found in chapter
+"7 Host System Management Port (HSMP)" of the family/model PPR
+Eg: https://www.amd.com/content/dam/amd/en/documents/epyc-technical-docs/programmer-references/55898_B1_pub_0_50.zip
+
+
+HSMP interface is supported on EPYC line of server CPUs and MI300A (APU).
+
+
+HSMP device
+============================================
+
+amd_hsmp driver under drivers/platforms/x86/amd/hsmp/ has separate driver files
+for ACPI object based probing, platform device based probing and for the common
+code for these two drivers.
+
+Kconfig option CONFIG_AMD_HSMP_PLAT compiles plat.c and creates amd_hsmp.ko.
+Kconfig option CONFIG_AMD_HSMP_ACPI compiles acpi.c and creates hsmp_acpi.ko.
+Selecting any of these two configs automatically selects CONFIG_AMD_HSMP. This
+compiles common code hsmp.c and creates hsmp_common.ko module.
+
+Both the ACPI and plat drivers create the miscdevice /dev/hsmp to let
+user space programs run hsmp mailbox commands.
+
+The ACPI object format supported by the driver is defined below.
+
+$ ls -al /dev/hsmp
+crw-r--r-- 1 root root 10, 123 Jan 21 21:41 /dev/hsmp
+
+Characteristics of the dev node:
+ * Write mode is used for running set/configure commands
+ * Read mode is used for running get/status monitor commands
+
+Access restrictions:
+ * Only root user is allowed to open the file in write mode.
+ * The file can be opened in read mode by all the users.
+
+In-kernel integration:
+ * Other subsystems in the kernel can use the exported transport
+ function hsmp_send_message().
+ * Locking across callers is taken care by the driver.
+
+
+HSMP sysfs interface
+====================
+
+1. Metrics table binary sysfs
+
+AMD MI300A MCM provides GET_METRICS_TABLE message to retrieve
+most of the system management information from SMU in one go.
+
+The metrics table is made available as hexadecimal sysfs binary file
+under per socket sysfs directory created at
+/sys/devices/platform/amd_hsmp/socket%d/metrics_bin
+
+Note: lseek() is not supported as entire metrics table is read.
+
+Metrics table definitions will be documented as part of Public PPR.
+The same is defined in the amd_hsmp.h header.
+
+2. HSMP telemetry sysfs files
+
+Following sysfs files are available at /sys/devices/platform/AMDI0097:0X/.
+
+* c0_residency_input: Percentage of cores in C0 state.
+* prochot_status: Reports 1 if the processor is at thermal threshold value,
+ 0 otherwise.
+* smu_fw_version: SMU firmware version.
+* protocol_version: HSMP interface version.
+* ddr_max_bw: Theoretical maximum DDR bandwidth in GB/s.
+* ddr_utilised_bw_input: Current utilized DDR bandwidth in GB/s.
+* ddr_utilised_bw_perc_input(%): Percentage of current utilized DDR bandwidth.
+* mclk_input: Memory clock in MHz.
+* fclk_input: Fabric clock in MHz.
+* clk_fmax: Maximum frequency of socket in MHz.
+* clk_fmin: Minimum frequency of socket in MHz.
+* cclk_freq_limit_input: Core clock frequency limit per socket in MHz.
+* pwr_current_active_freq_limit: Current active frequency limit of socket
+ in MHz.
+* pwr_current_active_freq_limit_source: Source of current active frequency
+ limit.
+
+ACPI device object format
+=========================
+The ACPI object format expected from the amd_hsmp driver
+for socket with ID00 is given below::
+
+ Device(HSMP)
+ {
+ Name(_HID, "AMDI0097")
+ Name(_UID, "ID00")
+ Name(HSE0, 0x00000001)
+ Name(RBF0, ResourceTemplate()
+ {
+ Memory32Fixed(ReadWrite, 0xxxxxxx, 0x00100000)
+ })
+ Method(_CRS, 0, NotSerialized)
+ {
+ Return(RBF0)
+ }
+ Method(_STA, 0, NotSerialized)
+ {
+ If(LEqual(HSE0, One))
+ {
+ Return(0x0F)
+ }
+ Else
+ {
+ Return(Zero)
+ }
+ }
+ Name(_DSD, Package(2)
+ {
+ Buffer(0x10)
+ {
+ 0x9D, 0x61, 0x4D, 0xB7, 0x07, 0x57, 0xBD, 0x48,
+ 0xA6, 0x9F, 0x4E, 0xA2, 0x87, 0x1F, 0xC2, 0xF6
+ },
+ Package(3)
+ {
+ Package(2) {"MsgIdOffset", 0x00010934},
+ Package(2) {"MsgRspOffset", 0x00010980},
+ Package(2) {"MsgArgOffset", 0x000109E0}
+ }
+ })
+ }
+
+HSMP HWMON interface
+====================
+HSMP power sensors are registered with the hwmon interface. A separate hwmon
+directory is created for each socket and the following files are generated
+within the hwmon directory.
+- power1_input (read only)
+- power1_cap_max (read only)
+- power1_cap (read, write)
+
+An example
+==========
+
+To access hsmp device from a C program.
+First, you need to include the headers::
+
+ #include <linux/amd_hsmp.h>
+
+Which defines the supported messages/message IDs.
+
+Next thing, open the device file, as follows::
+
+ int file;
+
+ file = open("/dev/hsmp", O_RDWR);
+ if (file < 0) {
+ /* ERROR HANDLING; you can check errno to see what went wrong */
+ exit(1);
+ }
+
+The following IOCTL is defined:
+
+``ioctl(file, HSMP_IOCTL_CMD, struct hsmp_message *msg)``
+ The argument is a pointer to a::
+
+ struct hsmp_message {
+ __u32 msg_id; /* Message ID */
+ __u16 num_args; /* Number of input argument words in message */
+ __u16 response_sz; /* Number of expected output/response words */
+ __u32 args[HSMP_MAX_MSG_LEN]; /* argument/response buffer */
+ __u16 sock_ind; /* socket number */
+ };
+
+The ioctl would return a non-zero on failure; you can read errno to see
+what happened. The transaction returns 0 on success.
+
+More details on the interface and message definitions can be found in chapter
+"7 Host System Management Port (HSMP)" of the respective family/model PPR
+eg: https://www.amd.com/content/dam/amd/en/documents/epyc-technical-docs/programmer-references/55898_B1_pub_0_50.zip

+===========================
+The Linux/x86 Boot Protocol
+===========================
+
+On the x86 platform, the Linux kernel uses a rather complicated boot
+convention. This has evolved partially due to historical aspects, as
+well as the desire in the early days to have the kernel itself be a
+bootable image, the complicated PC memory model and due to changed
+expectations in the PC industry caused by the effective demise of
+real-mode DOS as a mainstream operating system.
+
+Currently, the following versions of the Linux/x86 boot protocol exist.
+
+============= ============================================================
+Old kernels zImage/Image support only. Some very early kernels
+ may not even support a command line.
+
+Protocol 2.00 (Kernel 1.3.73) Added bzImage and initrd support, as
+ well as a formalized way to communicate between the
+ boot loader and the kernel. setup.S made relocatable,
+ although the traditional setup area still assumed
+ writable.
+
+Protocol 2.01 (Kernel 1.3.76) Added a heap overrun warning.
+
+Protocol 2.02 (Kernel 2.4.0-test3-pre3) New command line protocol.
+ Lower the conventional memory ceiling. No overwrite
+ of the traditional setup area, thus making booting
+ safe for systems which use the EBDA from SMM or 32-bit
+ BIOS entry points. zImage deprecated but still
+ supported.
+
+Protocol 2.03 (Kernel 2.4.18-pre1) Explicitly makes the highest possible
+ initrd address available to the bootloader.
+
+Protocol 2.04 (Kernel 2.6.14) Extend the syssize field to four bytes.
+
+Protocol 2.05 (Kernel 2.6.20) Make protected mode kernel relocatable.
+ Introduce relocatable_kernel and kernel_alignment fields.
+
+Protocol 2.06 (Kernel 2.6.22) Added a field that contains the size of
+ the boot command line.
+
+Protocol 2.07 (Kernel 2.6.24) Added paravirtualised boot protocol.
+ Introduced hardware_subarch and hardware_subarch_data
+ and KEEP_SEGMENTS flag in load_flags.
+
+Protocol 2.08 (Kernel 2.6.26) Added crc32 checksum and ELF format
+ payload. Introduced payload_offset and payload_length
+ fields to aid in locating the payload.
+
+Protocol 2.09 (Kernel 2.6.26) Added a field of 64-bit physical
+ pointer to single linked list of struct setup_data.
+
+Protocol 2.10 (Kernel 2.6.31) Added a protocol for relaxed alignment
+ beyond the kernel_alignment added, new init_size and
+ pref_address fields. Added extended boot loader IDs.
+
+Protocol 2.11 (Kernel 3.6) Added a field for offset of EFI handover
+ protocol entry point.
+
+Protocol 2.12 (Kernel 3.8) Added the xloadflags field and extension fields
+ to struct boot_params for loading bzImage and ramdisk
+ above 4G in 64bit.
+
+Protocol 2.13 (Kernel 3.14) Support 32- and 64-bit flags being set in
+ xloadflags to support booting a 64-bit kernel from 32-bit
+ EFI
+
+Protocol 2.14 BURNT BY INCORRECT COMMIT
+ ae7e1238e68f2a472a125673ab506d49158c1889
+ ("x86/boot: Add ACPI RSDP address to setup_header")
+ DO NOT USE!!! ASSUME SAME AS 2.13.
+
+Protocol 2.15 (Kernel 5.5) Added the kernel_info and kernel_info.setup_type_max.
+============= ============================================================
+
+.. note::
+ The protocol version number should be changed only if the setup header
+ is changed. There is no need to update the version number if boot_params
+ or kernel_info are changed. Additionally, it is recommended to use
+ xloadflags (in this case the protocol version number should not be
+ updated either) or kernel_info to communicate supported Linux kernel
+ features to the boot loader. Due to very limited space available in
+ the original setup header every update to it should be considered
+ with great care. Starting from the protocol 2.15 the primary way to
+ communicate things to the boot loader is the kernel_info.
+
+
+Memory Layout
+=============
+
+The traditional memory map for the kernel loader, used for Image or
+zImage kernels, typically looks like::
+
+ | |
+ 0A0000 +------------------------+
+ | Reserved for BIOS | Do not use. Reserved for BIOS EBDA.
+ 09A000 +------------------------+
+ | Command line |
+ | Stack/heap | For use by the kernel real-mode code.
+ 098000 +------------------------+
+ | Kernel setup | The kernel real-mode code.
+ 090200 +------------------------+
+ | Kernel boot sector | The kernel legacy boot sector.
+ 090000 +------------------------+
+ | Protected-mode kernel | The bulk of the kernel image.
+ 010000 +------------------------+
+ | Boot loader | <- Boot sector entry point 0000:7C00
+ 001000 +------------------------+
+ | Reserved for MBR/BIOS |
+ 000800 +------------------------+
+ | Typically used by MBR |
+ 000600 +------------------------+
+ | BIOS use only |
+ 000000 +------------------------+
+
+When using bzImage, the protected-mode kernel was relocated to
+0x100000 ("high memory"), and the kernel real-mode block (boot sector,
+setup, and stack/heap) was made relocatable to any address between
+0x10000 and end of low memory. Unfortunately, in protocols 2.00 and
+2.01 the 0x90000+ memory range is still used internally by the kernel;
+the 2.02 protocol resolves that problem.
+
+It is desirable to keep the "memory ceiling" -- the highest point in
+low memory touched by the boot loader -- as low as possible, since
+some newer BIOSes have begun to allocate some rather large amounts of
+memory, called the Extended BIOS Data Area, near the top of low
+memory. The boot loader should use the "INT 12h" BIOS call to verify
+how much low memory is available.
+
+Unfortunately, if INT 12h reports that the amount of memory is too
+low, there is usually nothing the boot loader can do but to report an
+error to the user. The boot loader should therefore be designed to
+take up as little space in low memory as it reasonably can. For
+zImage or old bzImage kernels, which need data written into the
+0x90000 segment, the boot loader should make sure not to use memory
+above the 0x9A000 point; too many BIOSes will break above that point.
+
+For a modern bzImage kernel with boot protocol version >= 2.02, a
+memory layout like the following is suggested::
+
+ ~ ~
+ | Protected-mode kernel |
+ 100000 +------------------------+
+ | I/O memory hole |
+ 0A0000 +------------------------+
+ | Reserved for BIOS | Leave as much as possible unused
+ ~ ~
+ | Command line | (Can also be below the X+10000 mark)
+ X+10000 +------------------------+
+ | Stack/heap | For use by the kernel real-mode code.
+ X+08000 +------------------------+
+ | Kernel setup | The kernel real-mode code.
+ | Kernel boot sector | The kernel legacy boot sector.
+ X +------------------------+
+ | Boot loader | <- Boot sector entry point 0000:7C00
+ 001000 +------------------------+
+ | Reserved for MBR/BIOS |
+ 000800 +------------------------+
+ | Typically used by MBR |
+ 000600 +------------------------+
+ | BIOS use only |
+ 000000 +------------------------+
+
+ ... where the address X is as low as the design of the boot loader permits.
+
+
+The Real-Mode Kernel Header
+===========================
+
+In the following text, and anywhere in the kernel boot sequence, "a
+sector" refers to 512 bytes. It is independent of the actual sector
+size of the underlying medium.
+
+The first step in loading a Linux kernel should be to load the
+real-mode code (boot sector and setup code) and then examine the
+following header at offset 0x01f1. The real-mode code can total up to
+32K, although the boot loader may choose to load only the first two
+sectors (1K) and then examine the bootup sector size.
+
+The header looks like:
+
+=========== ======== ===================== ============================================
+Offset/Size Proto Name Meaning
+=========== ======== ===================== ============================================
+01F1/1 ALL(1) setup_sects The size of the setup in sectors

+0264/4 2.11+ handover_offset Offset of handover entry point
+0268/4 2.15+ kernel_info_offset Offset of the kernel_info
+=========== ======== ===================== ============================================
+
+.. note::
+ (1) For backwards compatibility, if the setup_sects field contains 0,
+ the real value is 4.
+
+ (2) For boot protocol prior to 2.04, the upper two bytes of the syssize
+ field are unusable, which means the size of a bzImage kernel
+ cannot be determined.
+
+ (3) Ignored, but safe to set, for boot protocols 2.02-2.09.
+
+If the "HdrS" (0x53726448) magic number is not found at offset 0x202,
+the boot protocol version is "old". Loading an old kernel, the
+following parameters should be assumed::
+
+ Image type = zImage
+ initrd not supported
+ Real-mode kernel must be located at 0x90000.
+
+Otherwise, the "version" field contains the protocol version,
+e.g. protocol version 2.01 will contain 0x0201 in this field. When
+setting fields in the header, you must make sure only to set fields
+supported by the protocol version in use.
+
+
+Details of Header Fields
+========================
+
+For each field, some are information from the kernel to the bootloader
+("read"), some are expected to be filled out by the bootloader
+("write"), and some are expected to be read and modified by the
+bootloader ("modify").
+
+All general purpose boot loaders should write the fields marked
+(obligatory). Boot loaders who want to load the kernel at a
+nonstandard address should fill in the fields marked (reloc); other
+boot loaders can ignore those fields.
+
+The byte order of all fields is little endian (this is x86, after all.)
+
+============ ===========
+Field name: setup_sects
+Type: read
+Offset/size: 0x1f1/1
+Protocol: ALL
+============ ===========
+
+ The size of the setup code in 512-byte sectors. If this field is
+ 0, the real value is 4. The real-mode code consists of the boot
+ sector (always one 512-byte sector) plus the setup code.
+
+============ =================
+Field name: root_flags
+Type: modify (optional)
+Offset/size: 0x1f2/2
+Protocol: ALL
+============ =================
+
+ If this field is nonzero, the root defaults to readonly. The use of
+ this field is deprecated; use the "ro" or "rw" options on the
+ command line instead.
+
+============ ===============================================
+Field name: syssize
+Type: read
+Offset/size: 0x1f4/4 (protocol 2.04+) 0x1f4/2 (protocol ALL)
+Protocol: 2.04+
+============ ===============================================
+
+ The size of the protected-mode code in units of 16-byte paragraphs.
+ For protocol versions older than 2.04 this field is only two bytes
+ wide, and therefore cannot be trusted for the size of a kernel if
+ the LOAD_HIGH flag is set.
+
+============ ===============
+Field name: ram_size
+Type: kernel internal
+Offset/size: 0x1f8/2
+Protocol: ALL
+============ ===============
+
+ This field is obsolete.
+
+============ ===================
+Field name: vid_mode

+
+============ ===============
+Field name: setup_data
+Type: write (special)
+Offset/size: 0x250/8
+Protocol: 2.09+
+============ ===============
+
+ The 64-bit physical pointer to NULL terminated single linked list of
+ struct setup_data. This is used to define a more extensible boot
+ parameters passing mechanism. The definition of struct setup_data is
+ as follow::
+
+ struct setup_data {
+ __u64 next;
+ __u32 type;
+ __u32 len;
+ __u8 data[];
+ }
+
+ Where, the next is a 64-bit physical pointer to the next node of
+ linked list, the next field of the last node is 0; the type is used
+ to identify the contents of data; the len is the length of data
+ field; the data holds the real payload.
+
+ This list may be modified at a number of points during the bootup
+ process. Therefore, when modifying this list one should always make
+ sure to consider the case where the linked list already contains
+ entries.
+
+ The setup_data is a bit awkward to use for extremely large data objects,
+ both because the setup_data header has to be adjacent to the data object
+ and because it has a 32-bit length field. However, it is important that
+ intermediate stages of the boot process have a way to identify which
+ chunks of memory are occupied by kernel data.
+
+ Thus setup_indirect struct and SETUP_INDIRECT type were introduced in
+ protocol 2.15::
+
+ struct setup_indirect {
+ __u32 type;
+ __u32 reserved; /* Reserved, must be set to zero. */
+ __u64 len;
+ __u64 addr;
+ };
+
+ The type member is a SETUP_INDIRECT | SETUP_* type. However, it cannot be
+ SETUP_INDIRECT itself since making the setup_indirect a tree structure
+ could require a lot of stack space in something that needs to parse it
+ and stack space can be limited in boot contexts.
+
+ Let's give an example how to point to SETUP_E820_EXT data using setup_indirect.
+ In this case setup_data and setup_indirect will look like this::
+
+ struct setup_data {
+ .next = 0, /* or <addr_of_next_setup_data_struct> */
+ .type = SETUP_INDIRECT,
+ .len = sizeof(setup_indirect),
+ .data[sizeof(setup_indirect)] = (struct setup_indirect) {
+ .type = SETUP_INDIRECT | SETUP_E820_EXT,
+ .reserved = 0,
+ .len = <len_of_SETUP_E820_EXT_data>,
+ .addr = <addr_of_SETUP_E820_EXT_data>,
+ },
+ }
+
+.. note::
+ SETUP_INDIRECT | SETUP_NONE objects cannot be properly distinguished
+ from SETUP_INDIRECT itself. So, this kind of objects cannot be provided
+ by the bootloaders.
+
+============ ============
+Field name: pref_address
+Type: read (reloc)
+Offset/size: 0x258/8
+Protocol: 2.10+
+============ ============
+
+ This field, if nonzero, represents a preferred load address for the
+ kernel. A relocating bootloader should attempt to load at this
+ address if possible.
+
+ A non-relocatable kernel will unconditionally move itself and to run
+ at this address. A relocatable kernel will move itself to this address if it
+ loaded below this address.
+
+============ =======
+Field name: init_size
+Type: read
+Offset/size: 0x260/4
+============ =======
+
+ This field indicates the amount of linear contiguous memory starting
+ at the kernel runtime start address that the kernel needs before it
+ is capable of examining its memory map. This is not the same thing
+ as the total amount of memory the kernel needs to boot, but it can
+ be used by a relocating boot loader to help select a safe load
+ address for the kernel.
+
+ The kernel runtime start address is determined by the following algorithm::
+
+ if (relocatable_kernel) {
+ if (load_address < pref_address)
+ load_address = pref_address;
+ runtime_start = align_up(load_address, kernel_alignment);
+ } else {
+ runtime_start = pref_address;
+ }
+
+Hence the necessary memory window location and size can be estimated by
+a boot loader as::
+
+ memory_window_start = runtime_start;
+ memory_window_size = init_size;
+
+============ ===============
+Field name: handover_offset
+Type: read
+Offset/size: 0x264/4
+============ ===============
+
+ This field is the offset from the beginning of the kernel image to
+ the EFI handover protocol entry point. Boot loaders using the EFI
+ handover protocol to boot the kernel should jump to this offset.
+
+ See EFI HANDOVER PROTOCOL below for more details.
+
+============ ==================
+Field name: kernel_info_offset
+Type: read
+Offset/size: 0x268/4
+Protocol: 2.15+
+============ ==================
+
+ This field is the offset from the beginning of the kernel image to the
+ kernel_info. The kernel_info structure is embedded in the Linux image
+ in the uncompressed protected mode region.
+
+
+The kernel_info
+===============
+
+The relationships between the headers are analogous to the various data
+sections::
+
+ setup_header = .data
+ boot_params/setup_data = .bss
+
+What is missing from the above list? That's right::
+
+ kernel_info = .rodata
+
+We have been (ab)using .data for things that could go into .rodata or .bss for
+a long time, for lack of alternatives and -- especially early on -- inertia.
+Also, the BIOS stub is responsible for creating boot_params, so it isn't
+available to a BIOS-based loader (setup_data is, though).
+
+setup_header is permanently limited to 144 bytes due to the reach of the
+2-byte jump field, which doubles as a length field for the structure, combined
+with the size of the "hole" in struct boot_params that a protected-mode loader
+or the BIOS stub has to copy it into. It is currently 119 bytes long, which
+leaves us with 25 very precious bytes. This isn't something that can be fixed
+without revising the boot protocol entirely, breaking backwards compatibility.
+
+boot_params proper is limited to 4096 bytes, but can be arbitrarily extended
+by adding setup_data entries. It cannot be used to communicate properties of
+the kernel image, because it is .bss and has no image-provided content.
+
+kernel_info solves this by providing an extensible place for information about
+the kernel image. It is readonly, because the kernel cannot rely on a
+bootloader copying its contents anywhere, but that is OK; if it becomes
+necessary it can still contain data items that an enabled bootloader would be
+expected to copy into a setup_data chunk.
+
+All kernel_info data should be part of this structure. Fixed size data have to
+be put before kernel_info_var_len_data label. Variable size data have to be put
+after kernel_info_var_len_data label. Each chunk of variable size data has to
+be prefixed with header/magic and its size, e.g.::
+
+ kernel_info:
+ .ascii "LToP" /* Header, Linux top (structure). */
+ .long kernel_info_var_len_data - kernel_info
+ .long kernel_info_end - kernel_info
+ .long 0x01234567 /* Some fixed size data for the bootloaders. */
+ kernel_info_var_len_data:
+ example_struct: /* Some variable size data for the bootloaders. */
+ .ascii "0123" /* Header/Magic. */
+ .long example_struct_end - example_struct
+ .ascii "Struct"
+ .long 0x89012345
+ example_struct_end:
+ example_strings: /* Some variable size data for the bootloaders. */
+ .ascii "ABCD" /* Header/Magic. */
+ .long example_strings_end - example_strings
+ .asciz "String_0"
+ .asciz "String_1"
+ example_strings_end:
+ kernel_info_end:
+
+This way the kernel_info is self-contained blob.
+
+.. note::
+ Each variable size data header/magic can be any 4-character string,
+ without \0 at the end of the string, which does not collide with
+ existing variable length data headers/magics.

+
+The Kernel Command Line
+=======================
+
+The kernel command line has become an important way for the boot
+loader to communicate with the kernel. Some of its options are also
+relevant to the boot loader itself, see "special command line options"
+below.
+
+The kernel command line is a null-terminated string. The maximum
+length can be retrieved from the field cmdline_size. Before protocol
+version 2.06, the maximum was 255 characters. A string that is too
+long will be automatically truncated by the kernel.
+
+If the boot protocol version is 2.02 or later, the address of the
+kernel command line is given by the header field cmd_line_ptr (see
+above.) This address can be anywhere between the end of the setup
+heap and 0xA0000.
+
+If the protocol version is *not* 2.02 or higher, the kernel
+command line is entered using the following protocol:
+
+ - At offset 0x0020 (word), "cmd_line_magic", enter the magic
+ number 0xA33F.
+
+ - At offset 0x0022 (word), "cmd_line_offset", enter the offset
+ of the kernel command line (relative to the start of the
+ real-mode kernel).
+
+ - The kernel command line *must* be within the memory region
+ covered by setup_move_size, so you may need to adjust this
+ field.
+
+
+Memory Layout of The Real-Mode Code
+===================================
+
+The real-mode code requires a stack/heap to be set up, as well as
+memory allocated for the kernel command line. This needs to be done
+in the real-mode accessible memory in bottom megabyte.
+
+It should be noted that modern machines often have a sizable Extended
+BIOS Data Area (EBDA). As a result, it is advisable to use as little
+of the low megabyte as possible.
+
+Unfortunately, under the following circumstances the 0x90000 memory
+segment has to be used:
+
+ - When loading a zImage kernel ((loadflags & 0x01) == 0).
+ - When loading a 2.01 or earlier boot protocol kernel.
+
+.. note::
+ For the 2.00 and 2.01 boot protocols, the real-mode code
+ can be loaded at another address, but it is internally
+ relocated to 0x90000. For the "old" protocol, the
+ real-mode code must be loaded at 0x90000.
+
+When loading at 0x90000, avoid using memory above 0x9a000.
+
+For boot protocol 2.02 or higher, the command line does not have to be
+located in the same 64K segment as the real-mode setup code; it is
+thus permitted to give the stack/heap the full 64K segment and locate
+the command line above it.
+
+The kernel command line should not be located below the real-mode
+code, nor should it be located in high memory.
+
+
+Sample Boot Configuration
+=========================
+
+As a sample configuration, assume the following layout of the real
+mode segment.
+
+ When loading below 0x90000, use the entire segment:
+
+ ============= ===================
+ 0x0000-0x7fff Real mode kernel
+ 0x8000-0xdfff Stack and heap
+ 0xe000-0xffff Kernel command line
+ ============= ===================
+
+ When loading at 0x90000 OR the protocol version is 2.01 or earlier:
+
+ ============= ===================
+ 0x0000-0x7fff Real mode kernel
+ 0x8000-0x97ff Stack and heap
+ 0x9800-0x9fff Kernel command line
+ ============= ===================
+
+Such a boot loader should enter the following fields in the header::
+
+ unsigned long base_ptr; /* base address for real-mode segment */
+
+ if (setup_sects == 0)
+ setup_sects = 4;
+
+ if (protocol >= 0x0200) {
+ type_of_loader = <type code>;
+ if (loading_initrd) {
+ ramdisk_image = <initrd_address>;
+ ramdisk_size = <initrd_size>;
+ }
+
+ if (protocol >= 0x0202 && loadflags & 0x01)
+ heap_end = 0xe000;
+ else
+ heap_end = 0x9800;
+
+ if (protocol >= 0x0201) {
+ heap_end_ptr = heap_end - 0x200;
+ loadflags |= 0x80; /* CAN_USE_HEAP */
+ }
+
+ if (protocol >= 0x0202) {
+ cmd_line_ptr = base_ptr + heap_end;
+ strcpy(cmd_line_ptr, cmdline);
+ } else {
+ cmd_line_magic = 0xA33F;
+ cmd_line_offset = heap_end;
+ setup_move_size = heap_end + strlen(cmdline) + 1;
+ strcpy(base_ptr + cmd_line_offset, cmdline);
+ }
+ } else {
+ /* Very old kernel */
+
+ heap_end = 0x9800;
+
+ cmd_line_magic = 0xA33F;
+ cmd_line_offset = heap_end;
+
+ /* A very old kernel MUST have its real-mode code loaded at 0x90000 */
+ if (base_ptr != 0x90000) {
+ /* Copy the real-mode kernel */
+ memcpy(0x90000, base_ptr, (setup_sects + 1) * 512);
+ base_ptr = 0x90000; /* Relocated */
+ }
+
+ strcpy(0x90000 + cmd_line_offset, cmdline);
+
+ /* It is recommended to clear memory up to the 32K mark */
+ memset(0x90000 + (setup_sects + 1) * 512, 0, (64 - (setup_sects + 1)) * 512);
+ }
+
+
+Loading The Rest of The Kernel
+==============================
+
+The 32-bit (non-real-mode) kernel starts at offset (setup_sects + 1) * 512
+in the kernel file (again, if setup_sects == 0 the real value is 4.)
+It should be loaded at address 0x10000 for Image/zImage kernels and
+0x100000 for bzImage kernels.
+
+The kernel is a bzImage kernel if the protocol >= 2.00 and the 0x01
+bit (LOAD_HIGH) in the loadflags field is set::
+
+ is_bzImage = (protocol >= 0x0200) && (loadflags & 0x01);
+ load_address = is_bzImage ? 0x100000 : 0x10000;
+
+.. note::
+ Image/zImage kernels can be up to 512K in size, and thus use the entire
+ 0x10000-0x90000 range of memory. This means it is pretty much a
+ requirement for these kernels to load the real-mode part at 0x90000.
+ bzImage kernels allow much more flexibility.
+
+Special Command Line Options
+============================
+
+If the command line provided by the boot loader is entered by the
+user, the user may expect the following command line options to work.
+They should normally not be deleted from the kernel command line even
+though not all of them are actually meaningful to the kernel. Boot
+loader authors who need additional command line options for the boot
+loader itself should get them registered in
+Documentation/admin-guide/kernel-parameters.rst to make sure they will not
+conflict with actual kernel options now or in the future.
+
+ vga=<mode>
+ <mode> here is either an integer (in C notation, either
+ decimal, octal, or hexadecimal) or one of the strings
+ "normal" (meaning 0xFFFF), "ext" (meaning 0xFFFE) or "ask"
+ (meaning 0xFFFD). This value should be entered into the
+ vid_mode field, as it is used by the kernel before the command
+ line is parsed.
+
+ mem=<size>
+ <size> is an integer in C notation optionally followed by
+ (case insensitive) K, M, G, T, P or E (meaning << 10, << 20,
+ << 30, << 40, << 50 or << 60). This specifies the end of
+ memory to the kernel. This affects the possible placement of
+ an initrd, since an initrd should be placed near end of
+ memory. Note that this is an option to *both* the kernel and
+ the bootloader!
+
+ initrd=<file>
+ An initrd should be loaded. The meaning of <file> is
+ obviously bootloader-dependent, and some boot loaders
+ (e.g. LILO) do not have such a command.
+
+In addition, some boot loaders add the following options to the
+user-specified command line:
+
+ BOOT_IMAGE=<file>
+ The boot image which was loaded. Again, the meaning of <file>
+ is obviously bootloader-dependent.
+
+ auto
+ The kernel was booted without explicit user intervention.
+
+If these options are added by the boot loader, it is highly
+recommended that they are located *first*, before the user-specified
+or configuration-specified command line. Otherwise, "init=/bin/sh"
+gets confused by the "auto" option.
+
+
+Running the Kernel
+==================
+
+The kernel is started by jumping to the kernel entry point, which is
+located at *segment* offset 0x20 from the start of the real mode
+kernel. This means that if you loaded your real-mode kernel code at
+0x90000, the kernel entry point is 9020:0000.
+
+At entry, ds = es = ss should point to the start of the real-mode
+kernel code (0x9000 if the code is loaded at 0x90000), sp should be
+set up properly, normally pointing to the top of the heap, and
+interrupts should be disabled. Furthermore, to guard against bugs in
+the kernel, it is recommended that the boot loader sets fs = gs = ds =
+es = ss.
+
+In our example from above, we would do::
+
+ /*
+ * Note: in the case of the "old" kernel protocol, base_ptr must
+ * be == 0x90000 at this point; see the previous sample code.
+ */
+ seg = base_ptr >> 4;
+
+ cli(); /* Enter with interrupts disabled! */
+
+ /* Set up the real-mode kernel stack */
+ _SS = seg;
+ _SP = heap_end;
+
+ _DS = _ES = _FS = _GS = seg;
+ jmp_far(seg + 0x20, 0); /* Run the kernel */
+
+If your boot sector accesses a floppy drive, it is recommended to
+switch off the floppy motor before running the kernel, since the
+kernel boot leaves interrupts off and thus the motor will not be
+switched off, especially if the loaded kernel has the floppy driver as
+a demand-loaded module!
+
+
+Advanced Boot Loader Hooks
+==========================
+
+If the boot loader runs in a particularly hostile environment (such as
+LOADLIN, which runs under DOS) it may be impossible to follow the
+standard memory location requirements. Such a boot loader may use the
+following hooks that, if set, are invoked by the kernel at the
+appropriate time. The use of these hooks should probably be
+considered an absolutely last resort!
+
+IMPORTANT: All the hooks are required to preserve %esp, %ebp, %esi and
+%edi across invocation.
+
+ realmode_swtch:
+ A 16-bit real mode far subroutine invoked immediately before
+ entering protected mode. The default routine disables NMI, so
+ your routine should probably do so, too.
+
+ code32_start:
+ A 32-bit flat-mode routine *jumped* to immediately after the
+ transition to protected mode, but before the kernel is
+ uncompressed. No segments, except CS, are guaranteed to be
+ set up (current kernels do, but older ones do not); you should
+ set them up to BOOT_DS (0x18) yourself.
+
+ After completing your hook, you should jump to the address
+ that was in this field before your boot loader overwrote it
+ (relocated, if appropriate.)
+
+
+32-bit Boot Protocol
+====================
+
+For machine with some new BIOS other than legacy BIOS, such as EFI,
+LinuxBIOS, etc, and kexec, the 16-bit real mode setup code in kernel
+based on legacy BIOS can not be used, so a 32-bit boot protocol needs
+to be defined.
+
+In 32-bit boot protocol, the first step in loading a Linux kernel
+should be to setup the boot parameters (struct boot_params,
+traditionally known as "zero page"). The memory for struct boot_params
+should be allocated and initialized to all zero. Then the setup header
+from offset 0x01f1 of kernel image on should be loaded into struct
+boot_params and examined. The end of setup header can be calculated as
+follow::
+
+ 0x0202 + byte value at offset 0x0201
+
+In addition to read/modify/write the setup header of the struct
+boot_params as that of 16-bit boot protocol, the boot loader should
+also fill the additional fields of the struct boot_params as
+described in chapter Documentation/arch/x86/zero-page.rst.
+
+After setting up the struct boot_params, the boot loader can load the
+32/64-bit kernel in the same way as that of 16-bit boot protocol.
+
+In 32-bit boot protocol, the kernel is started by jumping to the
+32-bit kernel entry point, which is the start address of loaded
+32/64-bit kernel.
+
+At entry, the CPU must be in 32-bit protected mode with paging
+disabled; a GDT must be loaded with the descriptors for selectors
+__BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat
+segment; __BOOT_CS must have execute/read permission, and __BOOT_DS
+must have read/write permission; CS must be __BOOT_CS and DS, ES, SS
+must be __BOOT_DS; interrupt must be disabled; %esi must hold the base
+address of the struct boot_params; %ebp, %edi and %ebx must be zero.
+
+64-bit Boot Protocol
+====================
+
+For machine with 64bit cpus and 64bit kernel, we could use 64bit bootloader
+and we need a 64-bit boot protocol.
+
+In 64-bit boot protocol, the first step in loading a Linux kernel
+should be to setup the boot parameters (struct boot_params,
+traditionally known as "zero page"). The memory for struct boot_params
+could be allocated anywhere (even above 4G) and initialized to all zero.
+Then, the setup header at offset 0x01f1 of kernel image on should be
+loaded into struct boot_params and examined. The end of setup header
+can be calculated as follows::
+
+ 0x0202 + byte value at offset 0x0201
+
+In addition to read/modify/write the setup header of the struct
+boot_params as that of 16-bit boot protocol, the boot loader should
+also fill the additional fields of the struct boot_params as described
+in chapter Documentation/arch/x86/zero-page.rst.
+
+After setting up the struct boot_params, the boot loader can load
+64-bit kernel in the same way as that of 16-bit boot protocol, but
+kernel could be loaded above 4G.
+
+In 64-bit boot protocol, the kernel is started by jumping to the
+64-bit kernel entry point, which is the start address of loaded
+64-bit kernel plus 0x200.
+
+At entry, the CPU must be in 64-bit mode with paging enabled.
+The range with setup_header.init_size from start address of loaded
+kernel and zero page and command line buffer get ident mapping;
+a GDT must be loaded with the descriptors for selectors
+__BOOT_CS(0x10) and __BOOT_DS(0x18); both descriptors must be 4G flat
+segment; __BOOT_CS must have execute/read permission, and __BOOT_DS
+must have read/write permission; CS must be __BOOT_CS and DS, ES, SS
+must be __BOOT_DS; interrupt must be disabled; %rsi must hold the base
+address of the struct boot_params.
+
+EFI Handover Protocol (deprecated)
+==================================
+
+This protocol allows boot loaders to defer initialisation to the EFI
+boot stub. The boot loader is required to load the kernel/initrd(s)
+from the boot media and jump to the EFI handover protocol entry point
+which is hdr->handover_offset bytes from the beginning of
+startup_{32,64}.
+
+The boot loader MUST respect the kernel's PE/COFF metadata when it comes
+to section alignment, the memory footprint of the executable image beyond
+the size of the file itself, and any other aspect of the PE/COFF header
+that may affect correct operation of the image as a PE/COFF binary in the
+execution context provided by the EFI firmware.
+
+The function prototype for the handover entry point looks like this::
+
+ void efi_stub_entry(void *handle, efi_system_table_t *table, struct boot_params *bp);
+
+'handle' is the EFI image handle passed to the boot loader by the EFI
+firmware, 'table' is the EFI system table - these are the first two
+arguments of the "handoff state" as described in section 2.3 of the
+UEFI specification. 'bp' is the boot loader-allocated boot params.
+
+The boot loader *must* fill out the following fields in bp::
+
+ - hdr.cmd_line_ptr
+ - hdr.ramdisk_image (if applicable)
+ - hdr.ramdisk_size (if applicable)
+
+All other fields should be zero.
+
+.. note::
+ The EFI Handover Protocol is deprecated in favour of the ordinary PE/COFF
+ entry point described below.
+
+.. _pe-coff-entry-point:
+
+PE/COFF entry point
+===================
+
+When compiled with ``CONFIG_EFI_STUB=y``, the kernel can be executed as a
+regular PE/COFF binary. See Documentation/admin-guide/efi-stub.rst for
+implementation details.
+
+The stub loader can request the initrd via a UEFI protocol. For this to work,
+the firmware or bootloader needs to register a handle which carries
+implementations of the ``EFI_LOAD_FILE2`` protocol and the device path
+protocol exposing the ``LINUX_EFI_INITRD_MEDIA_GUID`` vendor media device path.
+In this case, a kernel booting via the EFI stub will invoke
+``LoadFile2::LoadFile()`` method on the registered protocol to instruct the
+firmware to load the initrd into a memory location chosen by the kernel/EFI
+stub.
+
+This approach removes the need for any knowledge on the part of the EFI
+bootloader regarding the internal representation of boot_params or any
+requirements/limitations regarding the placement of the command line and
+ramdisk in memory, or the placement of the kernel image itself.

+x86 Feature Flags
+=================
+
+Introduction
+============
+
+The list of feature flags in /proc/cpuinfo is not complete and
+represents an ill-fated attempt from long time ago to put feature flags
+in an easy to find place for userspace.
+
+However, the number of feature flags is growing with each CPU generation,
+leading to unparseable and unwieldy /proc/cpuinfo.
+
+What is more, those feature flags do not even need to be in that file
+because userspace doesn't care about them - glibc et al already use
+CPUID to find out what the target machine supports and what not.
+
+And even if it doesn't show a particular feature flag - although the CPU
+still does have support for the respective hardware functionality and
+said CPU supports CPUID faulting - userspace can simply probe for the
+feature and figure out if it is supported or not, regardless of whether
+it is being advertised somewhere.
+
+Furthermore, those flag strings become an ABI the moment they appear
+there and maintaining them forever when nothing even uses them is a lot
+of wasted effort.
+
+So, the current use of /proc/cpuinfo is to show features which the
+kernel has *enabled* and *supports*. As in: the CPUID feature flag is
+there, there's an additional setup which the kernel has done while
+booting and the functionality is ready to use. A perfect example for
+that is "user_shstk" where additional code enablement is present in the
+kernel to support shadow stack for user programs.
+
+So, if users want to know if a feature is available on a given system,
+they try to find the flag in /proc/cpuinfo. If a given flag is present,
+it means that
+
+* the kernel knows about the feature enough to have an X86_FEATURE bit
+
+* the kernel supports it and is currently making it available either to
+ userspace or some other part of the kernel
+
+* if the flag represents a hardware feature the hardware supports it.
+
+The absence of a flag in /proc/cpuinfo by itself means almost nothing to
+an end user.
+
+On the one hand, a feature like "vaes" might be fully available to user
+applications on a kernel that has not defined X86_FEATURE_VAES and thus
+there is no "vaes" in /proc/cpuinfo.
+
+On the other hand, a new kernel running on non-VAES hardware would also
+have no "vaes" in /proc/cpuinfo. There's no way for an application or
+user to tell the difference.
+
+The end result is that the flags field in /proc/cpuinfo is marginally
+useful for kernel debugging, but not really for anything else.
+Applications should instead use things like the glibc facilities for
+querying CPU support. Users should rely on tools like
+tools/arch/x86/kcpuid and cpuid(1).
+
+Regarding implementation, flags appearing in /proc/cpuinfo have an
+X86_FEATURE definition in arch/x86/include/asm/cpufeatures.h. These flags
+represent hardware features as well as software features.
+
+If the kernel cares about a feature or KVM want to expose the feature to
+a KVM guest, it should only then expose it to the guest when the guest
+needs to parse /proc/cpuinfo. Which, as mentioned above, is highly
+unlikely. KVM can synthesize the CPUID bit and the KVM guest can simply
+query CPUID and figure out what the hypervisor supports and what not. As
+already stated, /proc/cpuinfo is not a dumping ground for useless
+feature flags.
+
+
+How are feature flags created?
+==============================
+
+Feature flags can be derived from the contents of CPUID leaves
+--------------------------------------------------------------
+
+These feature definitions are organized mirroring the layout of CPUID
+leaves and grouped in words with offsets as mapped in enum cpuid_leafs
+in cpufeatures.h (see arch/x86/include/asm/cpufeatures.h for details).
+If a feature is defined with a X86_FEATURE_<name> definition in
+cpufeatures.h, and if it is detected at run time, the flags will be
+displayed accordingly in /proc/cpuinfo. For example, the flag "avx2"
+comes from X86_FEATURE_AVX2 in cpufeatures.h.
+
+Flags can be from scattered CPUID-based features
+------------------------------------------------
+
+Hardware features enumerated in sparsely populated CPUID leaves get
+software-defined values. Still, CPUID needs to be queried to determine
+if a given feature is present. This is done in init_scattered_cpuid_features().
+For instance, X86_FEATURE_CQM_LLC is defined as 11*32 + 0 and its presence is
+checked at runtime in the respective CPUID leaf [EAX=f, ECX=0] bit EDX[1].
+
+The intent of scattering CPUID leaves is to not bloat struct
+cpuinfo_x86.x86_capability[] unnecessarily. For instance, the CPUID leaf
+[EAX=7, ECX=0] has 30 features and is dense, but the CPUID leaf [EAX=7, EAX=1]
+has only one feature and would waste 31 bits of space in the x86_capability[]
+array. Since there is a struct cpuinfo_x86 for each possible CPU, the wasted
+memory is not trivial.
+
+Flags can be created synthetically under certain conditions for hardware features
+---------------------------------------------------------------------------------
+
+Examples of conditions include whether certain features are present in
+MSR_IA32_CORE_CAPS or specific CPU models are identified. If the needed
+conditions are met, the features are enabled by the set_cpu_cap or
+setup_force_cpu_cap macros. For example, if bit 5 is set in MSR_IA32_CORE_CAPS,
+the feature X86_FEATURE_SPLIT_LOCK_DETECT will be enabled and
+"split_lock_detect" will be displayed. The flag "ring3mwait" will be
+displayed only when running on INTEL_XEON_PHI_[KNL|KNM] processors.
+
+Flags can represent purely software features
+--------------------------------------------
+These flags do not represent hardware features. Instead, they represent a
+software feature implemented in the kernel. For example, Kernel Page Table
+Isolation is purely software feature and its feature flag X86_FEATURE_PTI is
+also defined in cpufeatures.h.
+
+Naming of Flags
+===============
+
+The script arch/x86/kernel/cpu/mkcapflags.sh processes the
+#define X86_FEATURE_<name> from cpufeatures.h and generates the
+x86_cap/bug_flags[] arrays in kernel/cpu/capflags.c. The names in the
+resulting x86_cap/bug_flags[] are used to populate /proc/cpuinfo. The naming
+of flags in the x86_cap/bug_flags[] are as follows:
+
+Flags do not appear by default in /proc/cpuinfo
+-----------------------------------------------
+
+Feature flags are omitted by default from /proc/cpuinfo as it does not make
+sense for the feature to be exposed to userspace in most cases. For example,
+X86_FEATURE_ALWAYS is defined in cpufeatures.h but that flag is an internal
+kernel feature used in the alternative runtime patching functionality. So the
+flag does not appear in /proc/cpuinfo.
+
+Specify a flag name if absolutely needed
+----------------------------------------
+
+If the comment on the line for the #define X86_FEATURE_* starts with a
+double-quote character (""), the string inside the double-quote characters
+will be the name of the flags. For example, the flag "sse4_1" comes from
+the comment "sse4_1" following the X86_FEATURE_XMM4_1 definition.
+
+There are situations in which overriding the displayed name of the flag is
+needed. For instance, /proc/cpuinfo is a userspace interface and must remain
+constant. If, for some reason, the naming of X86_FEATURE_<name> changes, one
+shall override the new naming with the name already used in /proc/cpuinfo.
+
+Flags are missing when one or more of these happen
+==================================================
+
+The hardware does not enumerate support for it
+----------------------------------------------
+
+For example, when a new kernel is running on old hardware or the feature is
+not enabled by boot firmware. Even if the hardware is new, there might be a
+problem enabling the feature at run time, the flag will not be displayed.
+
+The kernel does not know about the flag
+---------------------------------------
+
+For example, when an old kernel is running on new hardware.
+
+The kernel disabled support for it at compile-time
+--------------------------------------------------
+
+For example, if Linear Address Masking (LAM) is not enabled when building (i.e.,
+CONFIG_ADDRESS_MASKING is not selected) the flag "lam" will not show up.
+Even though the feature will still be detected via CPUID, the kernel disables
+it by clearing via setup_clear_cpu_cap(X86_FEATURE_LAM).
+
+The feature is disabled at boot-time
+------------------------------------
+A feature can be disabled either using a command-line parameter or because
+it failed to be enabled. The command-line parameter clearcpuid= can be used
+to disable features using the feature number as defined in
+/arch/x86/include/asm/cpufeatures.h. For instance, User Mode Instruction
+Protection can be disabled using clearcpuid=514. The number 514 is calculated
+from #define X86_FEATURE_UMIP (16*32 + 2).
+
+In addition, there exists a variety of custom command-line parameters that
+disable specific features. The list of parameters includes, but is not limited
+to, nofsgsbase, nosgx, noxsave, etc. 5-level paging can also be disabled using
+"no5lvl".
+
+The feature was known to be non-functional
+------------------------------------------
+
+The feature was known to be non-functional because a dependency was
+missing at runtime. For example, AVX flags will not show up if XSAVE feature
+is disabled since they depend on XSAVE feature. Another example would be broken
+CPUs and them missing microcode patches. Due to that, the kernel decides not to
+enable a feature.

+x86 IOMMU Support
+=================
+
+The architecture specs can be obtained from the below locations.
+
+- Intel: http://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/vt-directed-io-spec.pdf
+- AMD: https://www.amd.com/content/dam/amd/en/documents/processor-tech-docs/specifications/48882_3_07_PUB.pdf
+
+This guide gives a quick cheat sheet for some basic understanding.
+
+Basic stuff
+-----------
+
+ACPI enumerates and lists the different IOMMUs on the platform, and
+device scope relationships between devices and which IOMMU controls
+them.
+
+Some ACPI Keywords:
+
+- DMAR - Intel DMA Remapping table
+- DRHD - Intel DMA Remapping Hardware Unit Definition
+- RMRR - Intel Reserved Memory Region Reporting Structure
+- IVRS - AMD I/O Virtualization Reporting Structure
+- IVDB - AMD I/O Virtualization Definition Block
+- IVHD - AMD I/O Virtualization Hardware Definition
+
+What is Intel RMRR?
+^^^^^^^^^^^^^^^^^^^
+
+There are some devices the BIOS controls, for e.g USB devices to perform
+PS2 emulation. The regions of memory used for these devices are marked
+reserved in the e820 map. When we turn on DMA translation, DMA to those
+regions will fail. Hence BIOS uses RMRR to specify these regions along with
+devices that need to access these regions. OS is expected to setup
+unity mappings for these regions for these devices to access these regions.
+
+What is AMD IVRS?
+^^^^^^^^^^^^^^^^^
+
+The architecture defines an ACPI-compatible data structure called an I/O
+Virtualization Reporting Structure (IVRS) that is used to convey information
+related to I/O virtualization to system software. The IVRS describes the
+configuration and capabilities of the IOMMUs contained in the platform as
+well as information about the devices that each IOMMU virtualizes.
+
+The IVRS provides information about the following:
+
+- IOMMUs present in the platform including their capabilities and proper configuration
+- System I/O topology relevant to each IOMMU
+- Peripheral devices that cannot be otherwise enumerated
+- Memory regions used by SMI/SMM, platform firmware, and platform hardware. These are generally exclusion ranges to be configured by system software.
+
+How is an I/O Virtual Address (IOVA) generated?
+-----------------------------------------------
+
+Well behaved drivers call dma_map_*() calls before sending command to device
+that needs to perform DMA. Once DMA is completed and mapping is no longer
+required, driver performs dma_unmap_*() calls to unmap the region.
+
+Intel Specific Notes
+--------------------
+
+Graphics Problems?
+^^^^^^^^^^^^^^^^^^
+
+If you encounter issues with graphics devices, you can try adding
+option intel_iommu=igfx_off to turn off the integrated graphics engine.
+If this fixes anything, please ensure you file a bug reporting the problem.
+
+Some exceptions to IOVA
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Interrupt ranges are not address translated, (0xfee00000 - 0xfeefffff).
+The same is true for peer to peer transactions. Hence we reserve the
+address from PCI MMIO ranges so they are not allocated for IOVA addresses.
+
+AMD Specific Notes
+------------------
+
+Graphics Problems?
+^^^^^^^^^^^^^^^^^^
+
+If you encounter issues with integrated graphics devices, you can try adding
+option iommu=pt to the kernel command line use a 1:1 mapping for the IOMMU. If
+this fixes anything, please ensure you file a bug reporting the problem.
+
+Fault reporting
+---------------
+When errors are reported, the IOMMU signals via an interrupt. The fault
+reason and device that caused it is printed on the console.
+
+
+Kernel Log Samples
+------------------
+
+Intel Boot Messages
+^^^^^^^^^^^^^^^^^^^
+
+Something like this gets printed indicating presence of DMAR tables
+in ACPI:
+
+::
+
+ ACPI: DMAR (v001 A M I OEMDMAR 0x00000001 MSFT 0x00000097) @ 0x000000007f5b5ef0
+
+When DMAR is being processed and initialized by ACPI, prints DMAR locations
+and any RMRR's processed:
+
+::
+
+ ACPI DMAR:Host address width 36
+ ACPI DMAR:DRHD (flags: 0x00000000)base: 0x00000000fed90000
+ ACPI DMAR:DRHD (flags: 0x00000000)base: 0x00000000fed91000

+ ACPI DMAR:RMRR base: 0x000000007f600000 end: 0x000000007fffffff
+
+When DMAR is enabled for use, you will notice:
+
+::
+
+ PCI-DMA: Using DMAR IOMMU

+::
+

+======================================================
+Control-flow Enforcement Technology (CET) Shadow Stack
+======================================================
+
+CET Background
+==============
+
+Control-flow Enforcement Technology (CET) covers several related x86 processor
+features that provide protection against control flow hijacking attacks. CET
+can protect both applications and the kernel.
+
+CET introduces shadow stack and indirect branch tracking (IBT). A shadow stack
+is a secondary stack allocated from memory which cannot be directly modified by
+applications. When executing a CALL instruction, the processor pushes the
+return address to both the normal stack and the shadow stack. Upon
+function return, the processor pops the shadow stack copy and compares it
+to the normal stack copy. If the two differ, the processor raises a
+control-protection fault. IBT verifies indirect CALL/JMP targets are intended
+as marked by the compiler with 'ENDBR' opcodes. Not all CPU's have both Shadow
+Stack and Indirect Branch Tracking. Today in the 64-bit kernel, only userspace
+shadow stack and kernel IBT are supported.
+
+Requirements to use Shadow Stack
+================================
+
+To use userspace shadow stack you need HW that supports it, a kernel
+configured with it and userspace libraries compiled with it.
+
+The kernel Kconfig option is X86_USER_SHADOW_STACK. When compiled in, shadow
+stacks can be disabled at runtime with the kernel parameter: nousershstk.
+
+To build a user shadow stack enabled kernel, Binutils v2.29 or LLVM v6 or later
+are required.
+
+At run time, /proc/cpuinfo shows CET features if the processor supports
+CET. "user_shstk" means that userspace shadow stack is supported on the current
+kernel and HW.
+
+Application Enabling
+====================
+
+An application's CET capability is marked in its ELF note and can be verified
+from readelf/llvm-readelf output::
+
+ readelf -n <application> | grep -a SHSTK
+ properties: x86 feature: SHSTK
+
+The kernel does not process these applications markers directly. Applications
+or loaders must enable CET features using the interface described in section 4.
+Typically this would be done in dynamic loader or static runtime objects, as is
+the case in GLIBC.
+
+Enabling arch_prctl()'s
+=======================
+
+Elf features should be enabled by the loader using the below arch_prctl's. They
+are only supported in 64 bit user applications. These operate on the features
+on a per-thread basis. The enablement status is inherited on clone, so if the
+feature is enabled on the first thread, it will propagate to all the thread's
+in an app.
+
+arch_prctl(ARCH_SHSTK_ENABLE, unsigned long feature)
+ Enable a single feature specified in 'feature'. Can only operate on
+ one feature at a time.
+
+arch_prctl(ARCH_SHSTK_DISABLE, unsigned long feature)
+ Disable a single feature specified in 'feature'. Can only operate on
+ one feature at a time.
+
+arch_prctl(ARCH_SHSTK_LOCK, unsigned long features)
+ Lock in features at their current enabled or disabled status. 'features'
+ is a mask of all features to lock. All bits set are processed, unset bits
+ are ignored. The mask is ORed with the existing value. So any feature bits
+ set here cannot be enabled or disabled afterwards.
+
+arch_prctl(ARCH_SHSTK_UNLOCK, unsigned long features)
+ Unlock features. 'features' is a mask of all features to unlock. All
+ bits set are processed, unset bits are ignored. Only works via ptrace.
+
+arch_prctl(ARCH_SHSTK_STATUS, unsigned long addr)
+ Copy the currently enabled features to the address passed in addr. The
+ features are described using the bits passed into the others in
+ 'features'.
+
+The return values are as follows. On success, return 0. On error, errno can
+be::
+
+ -EPERM if any of the passed feature are locked.
+ -ENOTSUPP if the feature is not supported by the hardware or
+ kernel.
+ -EINVAL arguments (non existing feature, etc)
+ -EFAULT if could not copy information back to userspace
+
+The feature's bits supported are::
+
+ ARCH_SHSTK_SHSTK - Shadow stack
+ ARCH_SHSTK_WRSS - WRSS
+
+Currently shadow stack and WRSS are supported via this interface. WRSS
+can only be enabled with shadow stack, and is automatically disabled
+if shadow stack is disabled.
+
+Proc Status
+===========
+To check if an application is actually running with shadow stack, the
+user can read the /proc/$PID/status. It will report "wrss" or "shstk"
+depending on what is enabled. The lines look like this::
+
+ x86_Thread_features: shstk wrss
+ x86_Thread_features_locked: shstk wrss
+
+Implementation of the Shadow Stack
+==================================
+
+Shadow Stack Size
+-----------------
+
+A task's shadow stack is allocated from memory to a fixed size of
+MIN(RLIMIT_STACK, 4 GB). In other words, the shadow stack is allocated to
+the maximum size of the normal stack, but capped to 4 GB. In the case
+of the clone3 syscall, there is a stack size passed in and shadow stack
+uses this instead of the rlimit.
+
+Signal
+------
+
+The main program and its signal handlers use the same shadow stack. Because
+the shadow stack stores only return addresses, a large shadow stack covers
+the condition that both the program stack and the signal alternate stack run
+out.
+
+When a signal happens, the old pre-signal state is pushed on the stack. When
+shadow stack is enabled, the shadow stack specific state is pushed onto the
+shadow stack. Today this is only the old SSP (shadow stack pointer), pushed
+in a special format with bit 63 set. On sigreturn this old SSP token is
+verified and restored by the kernel. The kernel will also push the normal
+restorer address to the shadow stack to help userspace avoid a shadow stack
+violation on the sigreturn path that goes through the restorer.
+
+So the shadow stack signal frame format is as follows::
+
+ |1...old SSP| - Pointer to old pre-signal ssp in sigframe token format
+ (bit 63 set to 1)
+ | ...| - Other state may be added in the future
+
+
+32 bit ABI signals are not supported in shadow stack processes. Linux prevents
+32 bit execution while shadow stack is enabled by the allocating shadow stacks
+outside of the 32 bit address space. When execution enters 32 bit mode, either
+via far call or returning to userspace, a #GP is generated by the hardware
+which, will be delivered to the process as a segfault. When transitioning to
+userspace the register's state will be as if the userspace ip being returned to
+caused the segfault.
+
+Fork
+----
+
+The shadow stack's vma has VM_SHADOW_STACK flag set; its PTEs are required
+to be read-only and dirty. When a shadow stack PTE is not RO and dirty, a
+shadow access triggers a page fault with the shadow stack access bit set
+in the page fault error code.
+
+When a task forks a child, its shadow stack PTEs are copied and both the
+parent's and the child's shadow stack PTEs are cleared of the dirty bit.
+Upon the next shadow stack access, the resulting shadow stack page fault
+is handled by page copy/re-use.
+
+When a pthread child is created, the kernel allocates a new shadow stack
+for the new thread. New shadow stack creation behaves like mmap() with respect
+to ASLR behavior. Similarly, on thread exit the thread's shadow stack is
+disabled.
+
+Exec
+----
+
+On exec, shadow stack features are disabled by the kernel. At which point,
+userspace can choose to re-enable, or lock them.

+=====================================
+Intel Trust Domain Extensions (TDX)
+=====================================
+
+Intel's Trust Domain Extensions (TDX) protect confidential guest VMs from
+the host and physical attacks by isolating the guest register state and by
+encrypting the guest memory. In TDX, a special module running in a special
+mode sits between the host and the guest and manages the guest/host
+separation.
+
+TDX Host Kernel Support
+=======================
+
+TDX introduces a new CPU mode called Secure Arbitration Mode (SEAM) and
+a new isolated range pointed by the SEAM Ranger Register (SEAMRR). A
+CPU-attested software module called 'the TDX module' runs inside the new
+isolated range to provide the functionalities to manage and run protected
+VMs.
+
+TDX also leverages Intel Multi-Key Total Memory Encryption (MKTME) to
+provide crypto-protection to the VMs. TDX reserves part of MKTME KeyIDs
+as TDX private KeyIDs, which are only accessible within the SEAM mode.
+BIOS is responsible for partitioning legacy MKTME KeyIDs and TDX KeyIDs.
+
+Before the TDX module can be used to create and run protected VMs, it
+must be loaded into the isolated range and properly initialized. The TDX
+architecture doesn't require the BIOS to load the TDX module, but the
+kernel assumes it is loaded by the BIOS.
+
+TDX boot-time detection
+-----------------------
+
+The kernel detects TDX by detecting TDX private KeyIDs during kernel
+boot. Below dmesg shows when TDX is enabled by BIOS::
+
+ [..] virt/tdx: BIOS enabled: private KeyID range: [16, 64)
+
+TDX module initialization
+---------------------------------------
+
+The kernel talks to the TDX module via the new SEAMCALL instruction. The
+TDX module implements SEAMCALL leaf functions to allow the kernel to
+initialize it.
+
+If the TDX module isn't loaded, the SEAMCALL instruction fails with a
+special error. In this case the kernel fails the module initialization
+and reports the module isn't loaded::
+
+ [..] virt/tdx: module not loaded
+
+Initializing the TDX module consumes roughly ~1/256th system RAM size to
+use it as 'metadata' for the TDX memory. It also takes additional CPU
+time to initialize those metadata along with the TDX module itself. Both
+are not trivial. The kernel initializes the TDX module at runtime on
+demand.
+
+Besides initializing the TDX module, a per-cpu initialization SEAMCALL
+must be done on one cpu before any other SEAMCALLs can be made on that
+cpu.
+
+The kernel provides two functions, tdx_enable() and tdx_cpu_enable() to
+allow the user of TDX to enable the TDX module and enable TDX on local
+cpu respectively.
+
+Making SEAMCALL requires VMXON has been done on that CPU. Currently only
+KVM implements VMXON. For now both tdx_enable() and tdx_cpu_enable()
+don't do VMXON internally (not trivial), but depends on the caller to
+guarantee that.
+
+To enable TDX, the caller of TDX should: 1) temporarily disable CPU
+hotplug; 2) do VMXON and tdx_enable_cpu() on all online cpus; 3) call
+tdx_enable(). For example::
+
+ cpus_read_lock();
+ on_each_cpu(vmxon_and_tdx_cpu_enable());
+ ret = tdx_enable();
+ cpus_read_unlock();
+ if (ret)
+ goto no_tdx;
+ // TDX is ready to use
+
+And the caller of TDX must guarantee the tdx_cpu_enable() has been
+successfully done on any cpu before it wants to run any other SEAMCALL.
+A typical usage is do both VMXON and tdx_cpu_enable() in CPU hotplug
+online callback, and refuse to online if tdx_cpu_enable() fails.
+
+User can consult dmesg to see whether the TDX module has been initialized.
+
+If the TDX module is initialized successfully, dmesg shows something
+like below::
+
+ [..] virt/tdx: 262668 KBs allocated for PAMT
+ [..] virt/tdx: module initialized
+
+If the TDX module failed to initialize, dmesg also shows it failed to
+initialize::
+
+ [..] virt/tdx: module initialization failed ...
+
+TDX Interaction to Other Kernel Components
+------------------------------------------
+
+TDX Memory Policy
+~~~~~~~~~~~~~~~~~
+
+TDX reports a list of "Convertible Memory Region" (CMR) to tell the
+kernel which memory is TDX compatible. The kernel needs to build a list
+of memory regions (out of CMRs) as "TDX-usable" memory and pass those
+regions to the TDX module. Once this is done, those "TDX-usable" memory
+regions are fixed during module's lifetime.
+
+To keep things simple, currently the kernel simply guarantees all pages
+in the page allocator are TDX memory. Specifically, the kernel uses all
+system memory in the core-mm "at the time of TDX module initialization"
+as TDX memory, and in the meantime, refuses to online any non-TDX-memory
+in the memory hotplug.
+
+Physical Memory Hotplug
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Note TDX assumes convertible memory is always physically present during
+machine's runtime. A non-buggy BIOS should never support hot-removal of
+any convertible memory. This implementation doesn't handle ACPI memory
+removal but depends on the BIOS to behave correctly.
+
+CPU Hotplug
+~~~~~~~~~~~
+
+TDX module requires the per-cpu initialization SEAMCALL must be done on
+one cpu before any other SEAMCALLs can be made on that cpu. The kernel
+provides tdx_cpu_enable() to let the user of TDX to do it when the user
+wants to use a new cpu for TDX task.
+
+TDX doesn't support physical (ACPI) CPU hotplug. During machine boot,
+TDX verifies all boot-time present logical CPUs are TDX compatible before
+enabling TDX. A non-buggy BIOS should never support hot-add/removal of
+physical CPU. Currently the kernel doesn't handle physical CPU hotplug,
+but depends on the BIOS to behave correctly.
+
+Note TDX works with CPU logical online/offline, thus the kernel still
+allows to offline logical CPU and online it again.
+
+Erratum
+~~~~~~~
+
+The first few generations of TDX hardware have an erratum. A partial
+write to a TDX private memory cacheline will silently "poison" the
+line. Subsequent reads will consume the poison and generate a machine
+check.
+
+A partial write is a memory write where a write transaction of less than
+cacheline lands at the memory controller. The CPU does these via
+non-temporal write instructions (like MOVNTI), or through UC/WC memory
+mappings. Devices can also do partial writes via DMA.
+
+Theoretically, a kernel bug could do partial write to TDX private memory
+and trigger unexpected machine check. What's more, the machine check
+code will present these as "Hardware error" when they were, in fact, a
+software-triggered issue. But in the end, this issue is hard to trigger.
+
+If the platform has such erratum, the kernel prints additional message in
+machine check handler to tell user the machine check may be caused by
+kernel bug on TDX private memory.
+
+Kexec
+~~~~~~~
+
+Currently kexec doesn't work on the TDX platforms with the aforementioned
+erratum. It fails when loading the kexec kernel image. Otherwise it
+works normally.
+
+Interaction vs S3 and deeper states
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+TDX cannot survive from S3 and deeper states. The hardware resets and
+disables TDX completely when platform goes to S3 and deeper. Both TDX
+guests and the TDX module get destroyed permanently.
+
+The kernel uses S3 for suspend-to-ram, and use S4 and deeper states for
+hibernation. Currently, for simplicity, the kernel chooses to make TDX
+mutually exclusive with S3 and hibernation.
+
+The kernel disables TDX during early boot when hibernation support is
+available::
+
+ [..] virt/tdx: initialization failed: Hibernation support is enabled
+
+Add 'nohibernate' kernel command line to disable hibernation in order to
+use TDX.
+
+ACPI S3 is disabled during kernel early boot if TDX is enabled. The user
+needs to turn off TDX in the BIOS in order to use S3.
+
+TDX Guest Support
+=================
+Since the host cannot directly access guest registers or memory, much
+normal functionality of a hypervisor must be moved into the guest. This is
+implemented using a Virtualization Exception (#VE) that is handled by the
+guest kernel. A #VE is handled entirely inside the guest kernel, but some
+require the hypervisor to be consulted.
+
+TDX includes new hypercall-like mechanisms for communicating from the
+guest to the hypervisor or the TDX module.
+
+New TDX Exceptions
+------------------
+
+TDX guests behave differently from bare-metal and traditional VMX guests.
+In TDX guests, otherwise normal instructions or memory accesses can cause
+#VE or #GP exceptions.
+
+Instructions marked with an '*' conditionally cause exceptions. The
+details for these instructions are discussed below.
+
+Instruction-based #VE
+~~~~~~~~~~~~~~~~~~~~~
+
+- Port I/O (INS, OUTS, IN, OUT)
+- HLT
+- MONITOR, MWAIT
+- WBINVD, INVD
+- VMCALL
+- RDMSR*,WRMSR*
+- CPUID*
+
+Instruction-based #GP
+~~~~~~~~~~~~~~~~~~~~~
+
+- All VMX instructions: INVEPT, INVVPID, VMCLEAR, VMFUNC, VMLAUNCH,
+ VMPTRLD, VMPTRST, VMREAD, VMRESUME, VMWRITE, VMXOFF, VMXON
+- ENCLS, ENCLU
+- GETSEC
+- RSM
+- ENQCMD
+- RDMSR*,WRMSR*
+
+RDMSR/WRMSR Behavior
+~~~~~~~~~~~~~~~~~~~~
+
+MSR access behavior falls into three categories:
+
+- #GP generated
+- #VE generated
+- "Just works"
+
+In general, the #GP MSRs should not be used in guests. Their use likely
+indicates a bug in the guest. The guest may try to handle the #GP with a
+hypercall but it is unlikely to succeed.
+
+The #VE MSRs are typically able to be handled by the hypervisor. Guests
+can make a hypercall to the hypervisor to handle the #VE.
+
+The "just works" MSRs do not need any special guest handling. They might
+be implemented by directly passing through the MSR to the hardware or by
+trapping and handling in the TDX module. Other than possibly being slow,
+these MSRs appear to function just as they would on bare metal.
+
+CPUID Behavior
+~~~~~~~~~~~~~~
+
+For some CPUID leaves and sub-leaves, the virtualized bit fields of CPUID
+return values (in guest EAX/EBX/ECX/EDX) are configurable by the
+hypervisor. For such cases, the Intel TDX module architecture defines two
+virtualization types:
+
+- Bit fields for which the hypervisor controls the value seen by the guest
+ TD.
+
+- Bit fields for which the hypervisor configures the value such that the
+ guest TD either sees their native value or a value of 0. For these bit
+ fields, the hypervisor can mask off the native values, but it can not
+ turn *on* values.
+
+A #VE is generated for CPUID leaves and sub-leaves that the TDX module does
+not know how to handle. The guest kernel may ask the hypervisor for the
+value with a hypercall.
+
+#VE on Memory Accesses
+----------------------
+
+There are essentially two classes of TDX memory: private and shared.
+Private memory receives full TDX protections. Its content is protected
+against access from the hypervisor. Shared memory is expected to be
+shared between guest and hypervisor and does not receive full TDX
+protections.
+
+A TD guest is in control of whether its memory accesses are treated as
+private or shared. It selects the behavior with a bit in its page table
+entries. This helps ensure that a guest does not place sensitive
+information in shared memory, exposing it to the untrusted hypervisor.
+
+#VE on Shared Memory
+~~~~~~~~~~~~~~~~~~~~
+
+Access to shared mappings can cause a #VE. The hypervisor ultimately
+controls whether a shared memory access causes a #VE, so the guest must be
+careful to only reference shared pages it can safely handle a #VE. For
+instance, the guest should be careful not to access shared memory in the
+#VE handler before it reads the #VE info structure (TDG.VP.VEINFO.GET).
+
+Shared mapping content is entirely controlled by the hypervisor. The guest
+should only use shared mappings for communicating with the hypervisor.
+Shared mappings must never be used for sensitive memory content like kernel
+stacks. A good rule of thumb is that hypervisor-shared memory should be
+treated the same as memory mapped to userspace. Both the hypervisor and
+userspace are completely untrusted.
+
+MMIO for virtual devices is implemented as shared memory. The guest must
+be careful not to access device MMIO regions unless it is also prepared to
+handle a #VE.
+
+#VE on Private Pages
+~~~~~~~~~~~~~~~~~~~~
+
+An access to private mappings can also cause a #VE. Since all kernel
+memory is also private memory, the kernel might theoretically need to
+handle a #VE on arbitrary kernel memory accesses. This is not feasible, so
+TDX guests ensure that all guest memory has been "accepted" before memory
+is used by the kernel.
+
+A modest amount of memory (typically 512M) is pre-accepted by the firmware
+before the kernel runs to ensure that the kernel can start up without
+being subjected to a #VE.
+
+The hypervisor is permitted to unilaterally move accepted pages to a
+"blocked" state. However, if it does this, page access will not generate a
+#VE. It will, instead, cause a "TD Exit" where the hypervisor is required
+to handle the exception.
+
+Linux #VE handler
+-----------------
+
+Just like page faults or #GP's, #VE exceptions can be either handled or be
+fatal. Typically, an unhandled userspace #VE results in a SIGSEGV.
+An unhandled kernel #VE results in an oops.
+
+Handling nested exceptions on x86 is typically nasty business. A #VE
+could be interrupted by an NMI which triggers another #VE and hilarity
+ensues. The TDX #VE architecture anticipated this scenario and includes a
+feature to make it slightly less nasty.
+
+During #VE handling, the TDX module ensures that all interrupts (including
+NMIs) are blocked. The block remains in place until the guest makes a
+TDG.VP.VEINFO.GET TDCALL. This allows the guest to control when interrupts
+or a new #VE can be delivered.
+
+However, the guest kernel must still be careful to avoid potential
+#VE-triggering actions (discussed above) while this block is in place.
+While the block is in place, any #VE is elevated to a double fault (#DF)
+which is not recoverable.
+
+MMIO handling
+-------------
+
+In non-TDX VMs, MMIO is usually implemented by giving a guest access to a
+mapping which will cause a VMEXIT on access, and then the hypervisor
+emulates the access. That is not possible in TDX guests because VMEXIT
+will expose the register state to the host. TDX guests don't trust the host
+and can't have their state exposed to the host.
+
+In TDX, MMIO regions typically trigger a #VE exception in the guest. The
+guest #VE handler then emulates the MMIO instruction inside the guest and
+converts it into a controlled TDCALL to the host, rather than exposing
+guest state to the host.
+
+MMIO addresses on x86 are just special physical addresses. They can
+theoretically be accessed with any instruction that accesses memory.
+However, the kernel instruction decoding method is limited. It is only
+designed to decode instructions like those generated by io.h macros.
+
+MMIO access via other means (like structure overlays) may result in an
+oops.
+
+Shared Memory Conversions
+-------------------------
+
+All TDX guest memory starts out as private at boot. This memory can not
+be accessed by the hypervisor. However, some kernel users like device
+drivers might have a need to share data with the hypervisor. To do this,
+memory must be converted between shared and private. This can be
+accomplished using some existing memory encryption helpers:
+
+ * set_memory_decrypted() converts a range of pages to shared.
+ * set_memory_encrypted() converts memory back to private.
+
+Device drivers are the primary user of shared memory, but there's no need
+to touch every driver. DMA buffers and ioremap() do the conversions
+automatically.
+
+TDX uses SWIOTLB for most DMA allocations. The SWIOTLB buffer is
+converted to shared on boot.
+
+For coherent DMA allocation, the DMA buffer gets converted on the
+allocation. Check force_dma_unencrypted() for details.
+
+Attestation
+===========
+
+Attestation is used to verify the TDX guest trustworthiness to other
+entities before provisioning secrets to the guest. For example, a key
+server may want to use attestation to verify that the guest is the
+desired one before releasing the encryption keys to mount the encrypted
+rootfs or a secondary drive.
+
+The TDX module records the state of the TDX guest in various stages of
+the guest boot process using the build time measurement register (MRTD)
+and runtime measurement registers (RTMR). Measurements related to the
+guest initial configuration and firmware image are recorded in the MRTD
+register. Measurements related to initial state, kernel image, firmware
+image, command line options, initrd, ACPI tables, etc are recorded in
+RTMR registers. For more details, as an example, please refer to TDX
+Virtual Firmware design specification, section titled "TD Measurement".
+At TDX guest runtime, the attestation process is used to attest to these
+measurements.
+
+The attestation process consists of two steps: TDREPORT generation and
+Quote generation.
+
+TDX guest uses TDCALL[TDG.MR.REPORT] to get the TDREPORT (TDREPORT_STRUCT)
+from the TDX module. TDREPORT is a fixed-size data structure generated by
+the TDX module which contains guest-specific information (such as build
+and boot measurements), platform security version, and the MAC to protect
+the integrity of the TDREPORT. A user-provided 64-Byte REPORTDATA is used
+as input and included in the TDREPORT. Typically it can be some nonce
+provided by attestation service so the TDREPORT can be verified uniquely.
+More details about the TDREPORT can be found in Intel TDX Module
+specification, section titled "TDG.MR.REPORT Leaf".
+
+After getting the TDREPORT, the second step of the attestation process
+is to send it to the Quoting Enclave (QE) to generate the Quote. TDREPORT
+by design can only be verified on the local platform as the MAC key is
+bound to the platform. To support remote verification of the TDREPORT,
+TDX leverages Intel SGX Quoting Enclave to verify the TDREPORT locally
+and convert it to a remotely verifiable Quote. Method of sending TDREPORT
+to QE is implementation specific. Attestation software can choose
+whatever communication channel available (i.e. vsock or TCP/IP) to
+send the TDREPORT to QE and receive the Quote.

+============
+
+This documents and clarifies the main aspects of x86 topology modelling and
+representation in the kernel. Update/change when doing changes to the
+respective code.
+
+The architecture-agnostic topology definitions are in
+Documentation/admin-guide/cputopology.rst. This file holds x86-specific
+differences/specialities which must not necessarily apply to the generic
+definitions. Thus, the way to read up on Linux topology on x86 is to start
+with the generic one and look at this one in parallel for the x86 specifics.
+
+Needless to say, code should use the generic functions - this file is *only*
+here to *document* the inner workings of x86 topology.
+
+Started by Thomas Gleixner <tglx@linutronix.de> and Borislav Petkov <bp@alien8.de>.
+
+The main aim of the topology facilities is to present adequate interfaces to
+code which needs to know/query/use the structure of the running system wrt
+threads, cores, packages, etc.
+
+The kernel does not care about the concept of physical sockets because a
+socket has no relevance to software. It's an electromechanical component. In
+the past a socket always contained a single package (see below), but with the
+advent of Multi Chip Modules (MCM) a socket can hold more than one package. So
+there might be still references to sockets in the code, but they are of
+historical nature and should be cleaned up.
+
+The topology of a system is described in the units of:
+
+ - packages
+ - cores
+ - threads
+
+Package
+=======
+Packages contain a number of cores plus shared resources, e.g. DRAM
+controller, shared caches etc.
+
+Modern systems may also use the term 'Die' for package.
+
+AMD nomenclature for package is 'Node'.
+
+Package-related topology information in the kernel:
+
+ - topology_num_threads_per_package()
+
+ The number of threads in a package.
+
+ - topology_num_cores_per_package()
+
+ The number of cores in a package.
+
+ - topology_max_dies_per_package()
+
+ The maximum number of dies in a package.
+
+ - cpuinfo_x86.topo.die_id:
+
+ The physical ID of the die.
+
+ - cpuinfo_x86.topo.pkg_id:
+
+ The physical ID of the package. This information is retrieved via CPUID
+ and deduced from the APIC IDs of the cores in the package.
+
+ Modern systems use this value for the socket. There may be multiple
+ packages within a socket. This value may differ from topo.die_id.
+
+ - cpuinfo_x86.topo.logical_pkg_id:
+
+ The logical ID of the package. As we do not trust BIOSes to enumerate the
+ packages in a consistent way, we introduced the concept of logical package
+ ID so we can sanely calculate the number of maximum possible packages in
+ the system and have the packages enumerated linearly.
+
+ - topology_max_packages():
+
+ The maximum possible number of packages in the system. Helpful for per
+ package facilities to preallocate per package information.
+
+ - cpuinfo_x86.topo.llc_id:
+
+ - On Intel, the first APIC ID of the list of CPUs sharing the Last Level
+ Cache
+
+ - On AMD, the Node ID or Core Complex ID containing the Last Level
+ Cache. In general, it is a number identifying an LLC uniquely on the
+ system.
+
+Cores
+=====
+A core consists of 1 or more threads. It does not matter whether the threads
+are SMT- or CMT-type threads.
+
+AMDs nomenclature for a CMT core is "Compute Unit". The kernel always uses
+"core".
+
+Threads
+=======
+A thread is a single scheduling unit. It's the equivalent to a logical Linux
+CPU.
+
+AMDs nomenclature for CMT threads is "Compute Unit Core". The kernel always
+uses "thread".
+
+Thread-related topology information in the kernel:
+
+ - topology_core_cpumask():
+
+ The cpumask contains all online threads in the package to which a thread
+ belongs.
+
+ The number of online threads is also printed in /proc/cpuinfo "siblings."
+
+ - topology_sibling_cpumask():
+
+ The cpumask contains all online threads in the core to which a thread
+ belongs.
+
+ - topology_logical_package_id():
+
+ The logical package ID to which a thread belongs.
+
+ - topology_physical_package_id():
+
+ The physical package ID to which a thread belongs.
+
+ - topology_core_id();
+
+ The ID of the core to which a thread belongs. It is also printed in /proc/cpuinfo
+ "core_id."
+
+ - topology_logical_core_id();
+
+ The logical core ID to which a thread belongs.
+
+
+
+System topology enumeration
+===========================
+
+The topology on x86 systems can be discovered using a combination of vendor
+specific CPUID leaves which enumerate the processor topology and the cache
+hierarchy.
+
+The CPUID leaves in their preferred order of parsing for each x86 vendor is as
+follows:
+
+1) AMD
+
+ 1) CPUID leaf 0x80000026 [Extended CPU Topology] (Core::X86::Cpuid::ExCpuTopology)
+
+ The extended CPUID leaf 0x80000026 is the extension of the CPUID leaf 0xB
+ and provides the topology information of Core, Complex, CCD (Die), and
+ Socket in each level.
+
+ Support for the leaf is discovered by checking if the maximum extended
+ CPUID level is >= 0x80000026 and then checking if `LogProcAtThisLevel`
+ in `EBX[15:0]` at a particular level (starting from 0) is non-zero.
+
+ The `LevelType` in `ECX[15:8]` at the level provides the topology domain
+ the level describes - Core, Complex, CCD(Die), or the Socket.
+
+ The kernel uses the `CoreMaskWidth` from `EAX[4:0]` to discover the
+ number of bits that need to be right-shifted from `ExtendedLocalApicId`
+ in `EDX[31:0]` in order to get a unique Topology ID for the topology
+ level. CPUs with the same Topology ID share the resources at that level.
+
+ CPUID leaf 0x80000026 also provides more information regarding the power
+ and efficiency rankings, and about the core type on AMD processors with
+ heterogeneous characteristics.
+
+ If CPUID leaf 0x80000026 is supported, further parsing is not required.
+
+ 2) CPUID leaf 0x0000000B [Extended Topology Enumeration] (Core::X86::Cpuid::ExtTopEnum)
+
+ The extended CPUID leaf 0x0000000B is the predecessor on the extended
+ CPUID leaf 0x80000026 and only describes the core, and the socket domains
+ of the processor topology.
+
+ The support for the leaf is discovered by checking if the maximum supported
+ CPUID level is >= 0xB and then if `EBX[31:0]` at a particular level
+ (starting from 0) is non-zero.
+
+ The `LevelType` in `ECX[15:8]` at the level provides the topology domain
+ that the level describes - Thread, or Processor (Socket).
+
+ The kernel uses the `CoreMaskWidth` from `EAX[4:0]` to discover the
+ number of bits that need to be right-shifted from the `ExtendedLocalApicId`
+ in `EDX[31:0]` to get a unique Topology ID for that topology level. CPUs
+ sharing the Topology ID share the resources at that level.
+
+ If CPUID leaf 0xB is supported, further parsing is not required.
+
+
+ 3) CPUID leaf 0x80000008 ECX [Size Identifiers] (Core::X86::Cpuid::SizeId)
+
+ If neither the CPUID leaf 0x80000026 nor 0xB is supported, the number of
+ CPUs on the package is detected using the Size Identifier leaf
+ 0x80000008 ECX.
+
+ The support for the leaf is discovered by checking if the supported
+ extended CPUID level is >= 0x80000008.
+
+ The shifts from the APIC ID for the Socket ID is calculated from the
+ `ApicIdSize` field in `ECX[15:12]` if it is non-zero.
+
+ If `ApicIdSize` is reported to be zero, the shift is calculated as the
+ order of the `number of threads` calculated from `NC` field in
+ `ECX[7:0]` which describes the `number of threads - 1` on the package.
+
+ Unless Extended APIC ID is supported, the APIC ID used to find the
+ Socket ID is from the `LocalApicId` field of CPUID leaf 0x00000001
+ `EBX[31:24]`.
+
+ The topology parsing continues to detect if Extended APIC ID is
+ supported or not.
+
+
+ 4) CPUID leaf 0x8000001E [Extended APIC ID, Core Identifiers, Node Identifiers]
+ (Core::X86::Cpuid::{ExtApicId,CoreId,NodeId})
+
+ The support for Extended APIC ID can be detected by checking for the
+ presence of `TopologyExtensions` in `ECX[22]` of CPUID leaf 0x80000001
+ [Feature Identifiers] (Core::X86::Cpuid::FeatureExtIdEcx).
+
+ If Topology Extensions is supported, the APIC ID from `ExtendedApicId`
+ from CPUID leaf 0x8000001E `EAX[31:0]` should be preferred over that from
+ `LocalApicId` field of CPUID leaf 0x00000001 `EBX[31:24]` for topology
+ enumeration.
+
+ On processors of Family 0x17 and above that do not support CPUID leaf
+ 0x80000026 or CPUID leaf 0xB, the shifts from the APIC ID for the Core
+ ID is calculated using the order of `number of threads per core`
+ calculated using the `ThreadsPerCore` field in `EBX[15:8]` which
+ describes `number of threads per core - 1`.
+
+ On Processors of Family 0x15, the Core ID from `EBX[7:0]` is used as the
+ `cu_id` (Compute Unit ID) to detect CPUs that share the compute units.
+
+
+ All AMD processors that support the `TopologyExtensions` feature store the
+ `NodeId` from the `ECX[7:0]` of CPUID leaf 0x8000001E
+ (Core::X86::Cpuid::NodeId) as the per-CPU `node_id`. On older processors,
+ the `node_id` was discovered using MSR_FAM10H_NODE_ID MSR (MSR
+ 0x0xc001_100c). The presence of the NODE_ID MSR was detected by checking
+ `ECX[19]` of CPUID leaf 0x80000001 [Feature Identifiers]
+ (Core::X86::Cpuid::FeatureExtIdEcx).
+
+
+2) Intel
+
+ On Intel platforms, the CPUID leaves that enumerate the processor
+ topology are as follows:
+
+ 1) CPUID leaf 0x1F (V2 Extended Topology Enumeration Leaf)
+
+ The CPUID leaf 0x1F is the extension of the CPUID leaf 0xB and provides
+ the topology information of Core, Module, Tile, Die, DieGrp, and Socket
+ in each level.
+
+ The support for the leaf is discovered by checking if the supported
+ CPUID level is >= 0x1F and then `EBX[31:0]` at a particular level
+ (starting from 0) is non-zero.
+
+ The `Domain Type` in `ECX[15:8]` of the sub-leaf provides the topology
+ domain that the level describes - Core, Module, Tile, Die, DieGrp, and
+ Socket.
+
+ The kernel uses the value from `EAX[4:0]` to discover the number of
+ bits that need to be right shifted from the `x2APIC ID` in `EDX[31:0]`
+ to get a unique Topology ID for the topology level. CPUs with the same
+ Topology ID share the resources at that level.
+
+ If CPUID leaf 0x1F is supported, further parsing is not required.
+
+
+ 2) CPUID leaf 0x0000000B (Extended Topology Enumeration Leaf)
+
+ The extended CPUID leaf 0x0000000B is the predecessor of the V2 Extended
+ Topology Enumeration Leaf 0x1F and only describes the core, and the
+ socket domains of the processor topology.
+
+ The support for the leaf is iscovered by checking if the supported CPUID
+ level is >= 0xB and then checking if `EBX[31:0]` at a particular level
+ (starting from 0) is non-zero.
+
+ CPUID leaf 0x0000000B shares the same layout as CPUID leaf 0x1F and
+ should be enumerated in a similar manner.
+
+ If CPUID leaf 0xB is supported, further parsing is not required.
+
+
+ 3) CPUID leaf 0x00000004 (Deterministic Cache Parameters Leaf)
+
+ On Intel processors that support neither CPUID leaf 0x1F, nor CPUID leaf
+ 0xB, the shifts for the SMT domains is calculated using the number of
+ CPUs sharing the L1 cache.
+
+ Processors that feature Hyper-Threading is detected using `EDX[28]` of
+ CPUID leaf 0x1 (Basic CPUID Information).
+
+ The order of `Maximum number of addressable IDs for logical processors
+ sharing this cache` from `EAX[25:14]` of level-0 of CPUID 0x4 provides
+ the shifts from the APIC ID required to compute the Core ID.
+
+ The APIC ID and Package information is computed using the data from
+ CPUID leaf 0x1.
+
+
+ 4) CPUID leaf 0x00000001 (Basic CPUID Information)
+
+ The mask and shifts to derive the Physical Package (socket) ID is
+ computed using the `Maximum number of addressable IDs for logical
+ processors in this physical package` from `EBX[23:16]` of CPUID leaf
+ 0x1.
+
+ The APIC ID on the legacy platforms is derived from the `Initial APIC
+ ID` field from `EBX[31:24]` of CPUID leaf 0x1.
+
+
+3) Centaur and Zhaoxin
+
+ Similar to Intel, Centaur and Zhaoxin use a combination of CPUID leaf
+ 0x00000004 (Deterministic Cache Parameters Leaf) and CPUID leaf 0x00000001
+ (Basic CPUID Information) to derive the topology information.
+
+

+System topology examples

+ the same whether threads are enabled or not. That's merely an implementation
+ detail and has no practical impact.

+=========================================
+Flexible Return and Event Delivery (FRED)
+=========================================
+
+Overview
+========
+
+The FRED architecture defines simple new transitions that change
+privilege level (ring transitions). The FRED architecture was
+designed with the following goals:
+
+1) Improve overall performance and response time by replacing event
+ delivery through the interrupt descriptor table (IDT event
+ delivery) and event return by the IRET instruction with lower
+ latency transitions.
+
+2) Improve software robustness by ensuring that event delivery
+ establishes the full supervisor context and that event return
+ establishes the full user context.
+
+The new transitions defined by the FRED architecture are FRED event
+delivery and, for returning from events, two FRED return instructions.
+FRED event delivery can effect a transition from ring 3 to ring 0, but
+it is used also to deliver events incident to ring 0. One FRED
+instruction (ERETU) effects a return from ring 0 to ring 3, while the
+other (ERETS) returns while remaining in ring 0. Collectively, FRED
+event delivery and the FRED return instructions are FRED transitions.
+
+In addition to these transitions, the FRED architecture defines a new
+instruction (LKGS) for managing the state of the GS segment register.
+The LKGS instruction can be used by 64-bit operating systems that do
+not use the new FRED transitions.
+
+Furthermore, the FRED architecture is easy to extend for future CPU
+architectures.
+
+Software based event dispatching
+================================
+
+FRED operates differently from IDT in terms of event handling. Instead
+of directly dispatching an event to its handler based on the event
+vector, FRED requires the software to dispatch an event to its handler
+based on both the event's type and vector. Therefore, an event dispatch
+framework must be implemented to facilitate the event-to-handler
+dispatch process. The FRED event dispatch framework takes control
+once an event is delivered, and employs a two-level dispatch.
+
+The first level dispatching is event type based, and the second level
+dispatching is event vector based.
+
+Full supervisor/user context
+============================
+
+FRED event delivery atomically save and restore full supervisor/user
+context upon event delivery and return. Thus it avoids the problem of
+transient states due to %cr2 and/or %dr6, and it is no longer needed
+to handle all the ugly corner cases caused by half baked entry states.
+
+FRED allows explicit unblock of NMI with new event return instructions
+ERETS/ERETU, avoiding the mess caused by IRET which unconditionally
+unblocks NMI, e.g., when an exception happens during NMI handling.
+
+FRED always restores the full value of %rsp, thus ESPFIX is no longer
+needed when FRED is enabled.
+
+LKGS
+====
+
+LKGS behaves like the MOV to GS instruction except that it loads the
+base address into the IA32_KERNEL_GS_BASE MSR instead of the GS
+segment’s descriptor cache. With LKGS, it ends up with avoiding
+mucking with kernel GS, i.e., an operating system can always operate
+with its own GS base address.
+
+Because FRED event delivery from ring 3 and ERETU both swap the value
+of the GS base address and that of the IA32_KERNEL_GS_BASE MSR, plus
+the introduction of LKGS instruction, the SWAPGS instruction is no
+longer needed when FRED is enabled, thus is disallowed (#UD).
+
+Stack levels
+============
+
+4 stack levels 0~3 are introduced to replace the nonreentrant IST for
+event handling, and each stack level should be configured to use a
+dedicated stack.
+
+The current stack level could be unchanged or go higher upon FRED
+event delivery. If unchanged, the CPU keeps using the current event
+stack. If higher, the CPU switches to a new event stack specified by
+the MSR of the new stack level, i.e., MSR_IA32_FRED_RSP[123].
+
+Only execution of a FRED return instruction ERET[US], could lower the
+current stack level, causing the CPU to switch back to the stack it was
+on before a previous event delivery that promoted the stack level.

+ when seen both in absolute addresses and in distance-from-top notation.
+
+ For example 0xffffe90000000000 == -23 TB, it's 23 TB lower than the top of the
+ 64-bit address space (ffffffffffffffff).
+
+ Note that as we get closer to the top of the address space, the notation changes
+ from TB to GB and then MB/KB.
+
+ - "16M TB" might look weird at first sight, but it's an easier way to visualize size
+ notation than "16 EB", which few will recognize at first sight as 16 exabytes.
+ It also shows it nicely how incredibly large 64-bit address space is.

+Architecture defines a 64-bit virtual address. Implementations can support
+less. Currently supported are 48- and 57-bit virtual addresses. Bits 63
+through to the most-significant implemented bit are sign extended.
+This causes hole between user space and kernel addresses if you interpret them
+as unsigned.
+
+The direct mapping covers all memory in the system up to the highest

+
+We map EFI runtime services in the 'efi_pgd' PGD in a 64GB large virtual

+The mappings are not part of any other kernel PGD and are only available

+
+Note that if CONFIG_RANDOMIZE_MEMORY is enabled, the direct mapping of all

+General note on [U]EFI x86_64 support
+=====================================
+
+The nomenclature EFI and UEFI are used interchangeably in this document.
+
+Although the tools below are _not_ needed for building the kernel,
+the needed bootloader support and associated tools for x86_64 platforms
+with EFI firmware and specifications are listed below.
+
+1. UEFI specification: http://www.uefi.org
+
+2. Booting Linux kernel on UEFI x86_64 platform can either be
+ done using the <Documentation/admin-guide/efi-stub.rst> or using a
+ separate bootloader.
+
+3. x86_64 platform with EFI/UEFI firmware.
+
+Mechanics
+---------
+
+Refer to <Documentation/admin-guide/efi-stub.rst> to learn how to use the EFI stub.
+
+Below are general EFI setup guidelines on the x86_64 platform,
+regardless of whether you use the EFI stub or a separate bootloader.
+
+- Build the kernel with the following configuration::
+
+ CONFIG_FB_EFI=y
+ CONFIG_FRAMEBUFFER_CONSOLE=y
+
+ If EFI runtime services are expected, the following configuration should
+ be selected::
+
+ CONFIG_EFI=y
+ CONFIG_EFIVAR_FS=y or m # optional
+
+- Create a VFAT partition on the disk with the EFI System flag
+ You can do this with fdisk with the following commands:
+
+ 1. g - initialize a GPT partition table
+ 2. n - create a new partition
+ 3. t - change the partition type to "EFI System" (number 1)
+ 4. w - write and save the changes
+
+ Afterwards, initialize the VFAT filesystem by running mkfs::
+
+ mkfs.fat /dev/<your-partition>
+
+- Copy the boot files to the VFAT partition:
+ If you use the EFI stub method, the kernel acts also as an EFI executable.
+
+ You can just copy the bzImage to the EFI/boot/bootx64.efi path on the partition
+ so that it will automatically get booted, see the <Documentation/admin-guide/efi-stub.rst> page
+ for additional instructions regarding passage of kernel parameters and initramfs.
+
+ If you use a custom bootloader, refer to the relevant documentation for help on this part.
+
+- If some or all EFI runtime services don't work, you can try following
+ kernel command line parameters to turn off some or all EFI runtime
+ services.
+
+ noefi
+ turn off all EFI runtime services
+ reboot_type=k
+ turn off EFI reboot runtime service
+
+- If the EFI memory map has additional entries not in the E820 map,
+ you can include those entries in the kernels memory map of available
+ physical RAM by using the following kernel command line parameter.
+
+ add_efi_memmap
+ include EFI memory map of available physical RAM

+Using XSTATE features in user space applications
+================================================
+
+The x86 architecture supports floating-point extensions which are
+enumerated via CPUID. Applications consult CPUID and use XGETBV to
+evaluate which features have been enabled by the kernel XCR0.
+
+Up to AVX-512 and PKRU states, these features are automatically enabled by
+the kernel if available. Features like AMX TILE_DATA (XSTATE component 18)
+are enabled by XCR0 as well, but the first use of related instruction is
+trapped by the kernel because by default the required large XSTATE buffers
+are not allocated automatically.
+
+The purpose for dynamic features
+--------------------------------
+
+Legacy userspace libraries often have hard-coded, static sizes for
+alternate signal stacks, often using MINSIGSTKSZ which is typically 2KB.
+That stack must be able to store at *least* the signal frame that the
+kernel sets up before jumping into the signal handler. That signal frame
+must include an XSAVE buffer defined by the CPU.
+
+However, that means that the size of signal stacks is dynamic, not static,
+because different CPUs have differently-sized XSAVE buffers. A compiled-in
+size of 2KB with existing applications is too small for new CPU features
+like AMX. Instead of universally requiring larger stack, with the dynamic
+enabling, the kernel can enforce userspace applications to have
+properly-sized altstacks.
+
+Using dynamically enabled XSTATE features in user space applications
+--------------------------------------------------------------------
+
+The kernel provides an arch_prctl(2) based mechanism for applications to
+request the usage of such features. The arch_prctl(2) options related to
+this are:
+
+-ARCH_GET_XCOMP_SUPP
+
+ arch_prctl(ARCH_GET_XCOMP_SUPP, &features);
+
+ ARCH_GET_XCOMP_SUPP stores the supported features in userspace storage of
+ type uint64_t. The second argument is a pointer to that storage.
+
+-ARCH_GET_XCOMP_PERM
+
+ arch_prctl(ARCH_GET_XCOMP_PERM, &features);
+
+ ARCH_GET_XCOMP_PERM stores the features for which the userspace process
+ has permission in userspace storage of type uint64_t. The second argument
+ is a pointer to that storage.
+
+-ARCH_REQ_XCOMP_PERM
+
+ arch_prctl(ARCH_REQ_XCOMP_PERM, feature_nr);
+
+ ARCH_REQ_XCOMP_PERM allows to request permission for a dynamically enabled
+ feature or a feature set. A feature set can be mapped to a facility, e.g.
+ AMX, and can require one or more XSTATE components to be enabled.
+
+ The feature argument is the number of the highest XSTATE component which
+ is required for a facility to work.
+
+When requesting permission for a feature, the kernel checks the
+availability. The kernel ensures that sigaltstacks in the process's tasks
+are large enough to accommodate the resulting large signal frame. It
+enforces this both during ARCH_REQ_XCOMP_SUPP and during any subsequent
+sigaltstack(2) calls. If an installed sigaltstack is smaller than the
+resulting sigframe size, ARCH_REQ_XCOMP_SUPP results in -ENOSUPP. Also,
+sigaltstack(2) results in -ENOMEM if the requested altstack is too small
+for the permitted features.
+
+Permission, when granted, is valid per process. Permissions are inherited
+on fork(2) and cleared on exec(3).
+
+The first use of an instruction related to a dynamically enabled feature is
+trapped by the kernel. The trap handler checks whether the process has
+permission to use the feature. If the process has no permission then the
+kernel sends SIGILL to the application. If the process has permission then
+the handler allocates a larger xstate buffer for the task so the large
+state can be context switched. In the unlikely cases that the allocation
+fails, the kernel sends SIGSEGV.
+
+AMX TILE_DATA enabling example
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Below is the example of how userspace applications enable
+TILE_DATA dynamically:
+
+ 1. The application first needs to query the kernel for AMX
+ support::
+
+ #include <asm/prctl.h>
+ #include <sys/syscall.h>
+ #include <stdio.h>
+ #include <unistd.h>
+
+ #ifndef ARCH_GET_XCOMP_SUPP
+ #define ARCH_GET_XCOMP_SUPP 0x1021
+ #endif
+
+ #ifndef ARCH_XCOMP_TILECFG
+ #define ARCH_XCOMP_TILECFG 17
+ #endif
+
+ #ifndef ARCH_XCOMP_TILEDATA
+ #define ARCH_XCOMP_TILEDATA 18
+ #endif
+
+ #define MASK_XCOMP_TILE ((1 << ARCH_XCOMP_TILECFG) | \
+ (1 << ARCH_XCOMP_TILEDATA))
+
+ unsigned long features;
+ long rc;
+
+ ...
+
+ rc = syscall(SYS_arch_prctl, ARCH_GET_XCOMP_SUPP, &features);
+
+ if (!rc && (features & MASK_XCOMP_TILE) == MASK_XCOMP_TILE)
+ printf("AMX is available.\n");
+
+ 2. After that, determining support for AMX, an application must
+ explicitly ask permission to use it::
+
+ #ifndef ARCH_REQ_XCOMP_PERM
+ #define ARCH_REQ_XCOMP_PERM 0x1023
+ #endif
+
+ ...
+
+ rc = syscall(SYS_arch_prctl, ARCH_REQ_XCOMP_PERM, ARCH_XCOMP_TILEDATA);
+
+ if (!rc)
+ printf("AMX is ready for use.\n");
+
+Note this example does not include the sigaltstack preparation.
+
+Dynamic features in signal frames
+---------------------------------
+
+Dynamically enabled features are not written to the signal frame upon signal
+entry if the feature is in its initial configuration. This differs from
+non-dynamic features which are always written regardless of their
+configuration. Signal handlers can examine the XSAVE buffer's XSTATE_BV
+field to determine if a features was written.
+
+Dynamic features for virtual machines
+-------------------------------------
+
+The permission for the guest state component needs to be managed separately
+from the host, as they are exclusive to each other. A coupled of options
+are extended to control the guest permission:
+
+-ARCH_GET_XCOMP_GUEST_PERM
+
+ arch_prctl(ARCH_GET_XCOMP_GUEST_PERM, &features);
+
+ ARCH_GET_XCOMP_GUEST_PERM is a variant of ARCH_GET_XCOMP_PERM. So it
+ provides the same semantics and functionality but for the guest
+ components.
+
+-ARCH_REQ_XCOMP_GUEST_PERM
+
+ arch_prctl(ARCH_REQ_XCOMP_GUEST_PERM, feature_nr);
+
+ ARCH_REQ_XCOMP_GUEST_PERM is a variant of ARCH_REQ_XCOMP_PERM. It has the
+ same semantics for the guest permission. While providing a similar
+ functionality, this comes with a constraint. Permission is frozen when the
+ first VCPU is created. Any attempt to change permission after that point
+ is going to be rejected. So, the permission has to be requested before the
+ first VCPU creation.
+
+Note that some VMMs may have already established a set of supported state
+components. These options are not presumed to support any particular VMM.

-================================================
-The Unified Extensible Firmware Interface (UEFI)
-================================================
-
-UEFI, the Unified Extensible Firmware Interface, is a specification
-governing the behaviours of compatible firmware interfaces. It is
-maintained by the UEFI Forum - http://www.uefi.org/.
-
-UEFI is an evolution of its predecessor 'EFI', so the terms EFI and
-UEFI are used somewhat interchangeably in this document and associated
-source code. As a rule, anything new uses 'UEFI', whereas 'EFI' refers
-to legacy code or specifications.
-
-UEFI support in Linux
-=====================
-Booting on a platform with firmware compliant with the UEFI specification
-makes it possible for the kernel to support additional features:
-
-- UEFI Runtime Services
-- Retrieving various configuration information through the standardised
- interface of UEFI configuration tables. (ACPI, SMBIOS, ...)
-
-For actually enabling [U]EFI support, enable:
-
-- CONFIG_EFI=y
-- CONFIG_EFIVAR_FS=y or m
-
-The implementation depends on receiving information about the UEFI environment
-in a Flattened Device Tree (FDT) - so is only available with CONFIG_OF.
-
-UEFI stub
-=========
-The "stub" is a feature that extends the Image/zImage into a valid UEFI
-PE/COFF executable, including a loader application that makes it possible to
-load the kernel directly from the UEFI shell, boot menu, or one of the
-lightweight bootloaders like Gummiboot or rEFInd.
-
-The kernel image built with stub support remains a valid kernel image for
-booting in non-UEFI environments.
-
-UEFI kernel support on ARM
-==========================
-UEFI kernel support on the ARM architectures (arm and arm64) is only available
-when boot is performed through the stub.
-
-When booting in UEFI mode, the stub deletes any memory nodes from a provided DT.
-Instead, the kernel reads the UEFI memory map.
-
-The stub populates the FDT /chosen node with (and the kernel scans for) the
-following parameters:
-
-========================== ====== ===========================================
-Name Size Description
-========================== ====== ===========================================
-linux,uefi-system-table 64-bit Physical address of the UEFI System Table.
-
-linux,uefi-mmap-start 64-bit Physical address of the UEFI memory map,
- populated by the UEFI GetMemoryMap() call.
-
-linux,uefi-mmap-size 32-bit Size in bytes of the UEFI memory map
- pointed to in previous entry.
-
-linux,uefi-mmap-desc-size 32-bit Size in bytes of each entry in the UEFI
- memory map.
-
-linux,uefi-mmap-desc-ver 32-bit Version of the mmap descriptor format.
-
-kaslr-seed 64-bit Entropy used to randomize the kernel image
- base address location.

-=======================================================
-Activity Monitors Unit (AMU) extension in AArch64 Linux
-=======================================================
-
-Author: Ionela Voinescu <ionela.voinescu@arm.com>
-
-Date: 2019-09-10
-
-This document briefly describes the provision of Activity Monitors Unit
-support in AArch64 Linux.
-
-
-Architecture overview
----------------------
-
-The activity monitors extension is an optional extension introduced by the
-ARMv8.4 CPU architecture.
-
-The activity monitors unit, implemented in each CPU, provides performance
-counters intended for system management use. The AMU extension provides a
-system register interface to the counter registers and also supports an
-optional external memory-mapped interface.
-
-Version 1 of the Activity Monitors architecture implements a counter group
-of four fixed and architecturally defined 64-bit event counters.
-
- - CPU cycle counter: increments at the frequency of the CPU.
- - Constant counter: increments at the fixed frequency of the system
- clock.
- - Instructions retired: increments with every architecturally executed
- instruction.
- - Memory stall cycles: counts instruction dispatch stall cycles caused by
- misses in the last level cache within the clock domain.
-
-When in WFI or WFE these counters do not increment.
-
-The Activity Monitors architecture provides space for up to 16 architected
-event counters. Future versions of the architecture may use this space to
-implement additional architected event counters.
-
-Additionally, version 1 implements a counter group of up to 16 auxiliary
-64-bit event counters.
-
-On cold reset all counters reset to 0.
-
-
-Basic support
--------------
-
-The kernel can safely run a mix of CPUs with and without support for the
-activity monitors extension. Therefore, when CONFIG_ARM64_AMU_EXTN is
-selected we unconditionally enable the capability to allow any late CPU
-(secondary or hotplugged) to detect and use the feature.
-
-When the feature is detected on a CPU, we flag the availability of the
-feature but this does not guarantee the correct functionality of the
-counters, only the presence of the extension.
-
-Firmware (code running at higher exception levels, e.g. arm-tf) support is
-needed to:
-
- - Enable access for lower exception levels (EL2 and EL1) to the AMU
- registers.
- - Enable the counters. If not enabled these will read as 0.
- - Save/restore the counters before/after the CPU is being put/brought up
- from the 'off' power state.
-
-When using kernels that have this feature enabled but boot with broken
-firmware the user may experience panics or lockups when accessing the
-counter registers. Even if these symptoms are not observed, the values
-returned by the register reads might not correctly reflect reality. Most
-commonly, the counters will read as 0, indicating that they are not
-enabled.
-
-If proper support is not provided in firmware it's best to disable
-CONFIG_ARM64_AMU_EXTN. To be noted that for security reasons, this does not
-bypass the setting of AMUSERENR_EL0 to trap accesses from EL0 (userspace) to
-EL1 (kernel). Therefore, firmware should still ensure accesses to AMU registers
-are not trapped in EL2/EL3.
-
-The fixed counters of AMUv1 are accessible though the following system
-register definitions:
-
- - SYS_AMEVCNTR0_CORE_EL0
- - SYS_AMEVCNTR0_CONST_EL0
- - SYS_AMEVCNTR0_INST_RET_EL0
- - SYS_AMEVCNTR0_MEM_STALL_EL0
-
-Auxiliary platform specific counters can be accessed using
-SYS_AMEVCNTR1_EL0(n), where n is a value between 0 and 15.
-
-Details can be found in: arch/arm64/include/asm/sysreg.h.
-
-
-Userspace access
-----------------
-
-Currently, access from userspace to the AMU registers is disabled due to:
-
- - Security reasons: they might expose information about code executed in
- secure mode.
- - Purpose: AMU counters are intended for system management use.
-
-Also, the presence of the feature is not visible to userspace.
-
-
-Virtualization
---------------
-
-Currently, access from userspace (EL0) and kernelspace (EL1) on the KVM
-guest side is disabled due to:
-
- - Security reasons: they might expose information about code executed
- by other guests or the host.
-
-Any attempt to access the AMU registers will result in an UNDEFINED
-exception being injected into the guest.

-=====================
-Booting AArch64 Linux
-=====================
-
-Author: Will Deacon <will.deacon@arm.com>
-
-Date : 07 September 2012
-
-This document is based on the ARM booting document by Russell King and
-is relevant to all public releases of the AArch64 Linux kernel.
-
-The AArch64 exception model is made up of a number of exception levels
-(EL0 - EL3), with EL0, EL1 and EL2 having a secure and a non-secure
-counterpart. EL2 is the hypervisor level, EL3 is the highest priority
-level and exists only in secure mode. Both are architecturally optional.
-
-For the purposes of this document, we will use the term `boot loader`
-simply to define all software that executes on the CPU(s) before control
-is passed to the Linux kernel. This may include secure monitor and
-hypervisor code, or it may just be a handful of instructions for
-preparing a minimal boot environment.
-
-Essentially, the boot loader should provide (as a minimum) the
-following:
-
-1. Setup and initialise the RAM
-2. Setup the device tree
-3. Decompress the kernel image
-4. Call the kernel image
-
-
-1. Setup and initialise RAM
----------------------------
-
-Requirement: MANDATORY
-
-The boot loader is expected to find and initialise all RAM that the
-kernel will use for volatile data storage in the system. It performs
-this in a machine dependent manner. (It may use internal algorithms
-to automatically locate and size all RAM, or it may use knowledge of
-the RAM in the machine, or any other method the boot loader designer
-sees fit.)
-
-
-2. Setup the device tree
--------------------------
-
-Requirement: MANDATORY
-
-The device tree blob (dtb) must be placed on an 8-byte boundary and must
-not exceed 2 megabytes in size. Since the dtb will be mapped cacheable
-using blocks of up to 2 megabytes in size, it must not be placed within
-any 2M region which must be mapped with any specific attributes.
-
-NOTE: versions prior to v4.2 also require that the DTB be placed within
-the 512 MB region starting at text_offset bytes below the kernel Image.
-
-3. Decompress the kernel image
-------------------------------
-
-Requirement: OPTIONAL
-
-The AArch64 kernel does not currently provide a decompressor and
-therefore requires decompression (gzip etc.) to be performed by the boot
-loader if a compressed Image target (e.g. Image.gz) is used. For
-bootloaders that do not implement this requirement, the uncompressed
-Image target is available instead.
-
-
-4. Call the kernel image
-------------------------
-
-Requirement: MANDATORY
-
-The decompressed kernel image contains a 64-byte header as follows::
-
- u32 code0; /* Executable code */
- u32 code1; /* Executable code */
- u64 text_offset; /* Image load offset, little endian */
- u64 image_size; /* Effective Image size, little endian */
- u64 flags; /* kernel flags, little endian */
- u64 res2 = 0; /* reserved */
- u64 res3 = 0; /* reserved */
- u64 res4 = 0; /* reserved */
- u32 magic = 0x644d5241; /* Magic number, little endian, "ARM\x64" */
- u32 res5; /* reserved (used for PE COFF offset) */
-
-
-Header notes:
-
-- As of v3.17, all fields are little endian unless stated otherwise.
-
-- code0/code1 are responsible for branching to stext.
-
-- when booting through EFI, code0/code1 are initially skipped.
- res5 is an offset to the PE header and the PE header has the EFI
- entry point (efi_stub_entry). When the stub has done its work, it
- jumps to code0 to resume the normal boot process.
-
-- Prior to v3.17, the endianness of text_offset was not specified. In
- these cases image_size is zero and text_offset is 0x80000 in the
- endianness of the kernel. Where image_size is non-zero image_size is
- little-endian and must be respected. Where image_size is zero,
- text_offset can be assumed to be 0x80000.
-
-- The flags field (introduced in v3.17) is a little-endian 64-bit field
- composed as follows:
-
- ============= ===============================================================
- Bit 0 Kernel endianness. 1 if BE, 0 if LE.
- Bit 1-2 Kernel Page size.
-
- * 0 - Unspecified.
- * 1 - 4K
- * 2 - 16K
- * 3 - 64K
- Bit 3 Kernel physical placement
-
- 0
- 2MB aligned base should be as close as possible
- to the base of DRAM, since memory below it is not
- accessible via the linear mapping
- 1
- 2MB aligned base such that all image_size bytes
- counted from the start of the image are within
- the 48-bit addressable range of physical memory
- Bits 4-63 Reserved.
- ============= ===============================================================
-
-- When image_size is zero, a bootloader should attempt to keep as much
- memory as possible free for use by the kernel immediately after the
- end of the kernel image. The amount of space required will vary
- depending on selected features, and is effectively unbound.
-
-The Image must be placed text_offset bytes from a 2MB aligned base
-address anywhere in usable system RAM and called there. The region
-between the 2 MB aligned base address and the start of the image has no
-special significance to the kernel, and may be used for other purposes.
-At least image_size bytes from the start of the image must be free for
-use by the kernel.
-NOTE: versions prior to v4.6 cannot make use of memory below the
-physical offset of the Image so it is recommended that the Image be
-placed as close as possible to the start of system RAM.
-
-If an initrd/initramfs is passed to the kernel at boot, it must reside
-entirely within a 1 GB aligned physical memory window of up to 32 GB in
-size that fully covers the kernel Image as well.
-
-Any memory described to the kernel (even that below the start of the
-image) which is not marked as reserved from the kernel (e.g., with a
-memreserve region in the device tree) will be considered as available to
-the kernel.
-
-Before jumping into the kernel, the following conditions must be met:
-
-- Quiesce all DMA capable devices so that memory does not get
- corrupted by bogus network packets or disk data. This will save
- you many hours of debug.
-
-- Primary CPU general-purpose register settings:
-
- - x0 = physical address of device tree blob (dtb) in system RAM.
- - x1 = 0 (reserved for future use)
- - x2 = 0 (reserved for future use)
- - x3 = 0 (reserved for future use)
-
-- CPU mode
-
- All forms of interrupts must be masked in PSTATE.DAIF (Debug, SError,
- IRQ and FIQ).
- The CPU must be in non-secure state, either in EL2 (RECOMMENDED in order
- to have access to the virtualisation extensions), or in EL1.
-
-- Caches, MMUs
-
- The MMU must be off.
-
- The instruction cache may be on or off, and must not hold any stale
- entries corresponding to the loaded kernel image.
-
- The address range corresponding to the loaded kernel image must be
- cleaned to the PoC. In the presence of a system cache or other
- coherent masters with caches enabled, this will typically require
- cache maintenance by VA rather than set/way operations.
- System caches which respect the architected cache maintenance by VA
- operations must be configured and may be enabled.
- System caches which do not respect architected cache maintenance by VA
- operations (not recommended) must be configured and disabled.
-
-- Architected timers
-
- CNTFRQ must be programmed with the timer frequency and CNTVOFF must
- be programmed with a consistent value on all CPUs. If entering the
- kernel at EL1, CNTHCTL_EL2 must have EL1PCTEN (bit 0) set where
- available.
-
-- Coherency
-
- All CPUs to be booted by the kernel must be part of the same coherency
- domain on entry to the kernel. This may require IMPLEMENTATION DEFINED
- initialisation to enable the receiving of maintenance operations on
- each CPU.
-
-- System registers
-
- All writable architected system registers at or below the exception
- level where the kernel image will be entered must be initialised by
- software at a higher exception level to prevent execution in an UNKNOWN
- state.
-

- - If EL3 is present:

- - If the kernel is entered at EL1 and EL2 is present:
-
- - HCR_EL2.ATA (bit 56) must be initialised to 0b1.
-
- For CPUs with the Scalable Matrix Extension version 2 (FEAT_SME2):
-
- - If EL3 is present:
-
- - SMCR_EL3.EZT0 (bit 30) must be initialised to 0b1.
-
- - If the kernel is entered at EL1 and EL2 is present:
-
- - SMCR_EL2.EZT0 (bit 30) must be initialised to 0b1.
-
-The requirements described above for CPU mode, caches, MMUs, architected
-timers, coherency and system registers apply to all CPUs. All CPUs must
-enter the kernel in the same exception level. Where the values documented
-disable traps it is permissible for these traps to be enabled so long as
-those traps are handled transparently by higher exception levels as though
-the values documented were set.
-
-The boot loader is expected to enter the kernel on each CPU in the
-following manner:
-
-- The primary CPU must jump directly to the first instruction of the
- kernel image. The device tree blob passed by this CPU must contain
- an 'enable-method' property for each cpu node. The supported
- enable-methods are described below.
-
- It is expected that the bootloader will generate these device tree
- properties and insert them into the blob prior to kernel entry.
-
-- CPUs with a "spin-table" enable-method must have a 'cpu-release-addr'
- property in their cpu node. This property identifies a
- naturally-aligned 64-bit zero-initalised memory location.
-
- These CPUs should spin outside of the kernel in a reserved area of
- memory (communicated to the kernel by a /memreserve/ region in the
- device tree) polling their cpu-release-addr location, which must be
- contained in the reserved region. A wfe instruction may be inserted
- to reduce the overhead of the busy-loop and a sev will be issued by
- the primary CPU. When a read of the location pointed to by the
- cpu-release-addr returns a non-zero value, the CPU must jump to this
- value. The value will be written as a single 64-bit little-endian
- value, so CPUs must convert the read value to their native endianness
- before jumping to it.
-
-- CPUs with a "psci" enable method should remain outside of
- the kernel (i.e. outside of the regions of memory described to the
- kernel in the memory node, or in a reserved area of memory described
- to the kernel by a /memreserve/ region in the device tree). The
- kernel will issue CPU_ON calls as described in ARM document number ARM
- DEN 0022A ("Power State Coordination Interface System Software on ARM
- processors") to bring CPUs into the kernel.
-
- The device tree should contain a 'psci' node, as described in
- Documentation/devicetree/bindings/arm/psci.yaml.
-
-- Secondary CPU general-purpose register settings

- - x0 = 0 (reserved for future use)
- - x1 = 0 (reserved for future use)
- - x2 = 0 (reserved for future use)
- - x3 = 0 (reserved for future use)

-================
-ARM64 ELF hwcaps
-================
-
-This document describes the usage and semantics of the arm64 ELF hwcaps.
-
-
-1. Introduction
----------------
-
-Some hardware or software features are only available on some CPU
-implementations, and/or with certain kernel configurations, but have no
-architected discovery mechanism available to userspace code at EL0. The
-kernel exposes the presence of these features to userspace through a set
-of flags called hwcaps, exposed in the auxiliary vector.
-
-Userspace software can test for features by acquiring the AT_HWCAP or
-AT_HWCAP2 entry of the auxiliary vector, and testing whether the relevant
-flags are set, e.g.::
-
- bool floating_point_is_present(void)
- {
- unsigned long hwcaps = getauxval(AT_HWCAP);
- if (hwcaps & HWCAP_FP)
- return true;
-
- return false;
- }
-
-Where software relies on a feature described by a hwcap, it should check
-the relevant hwcap flag to verify that the feature is present before
-attempting to make use of the feature.
-
-Features cannot be probed reliably through other means. When a feature
-is not available, attempting to use it may result in unpredictable
-behaviour, and is not guaranteed to result in any reliable indication
-that the feature is unavailable, such as a SIGILL.
-
-
-2. Interpretation of hwcaps
----------------------------
-
-The majority of hwcaps are intended to indicate the presence of features
-which are described by architected ID registers inaccessible to
-userspace code at EL0. These hwcaps are defined in terms of ID register
-fields, and should be interpreted with reference to the definition of
-these fields in the ARM Architecture Reference Manual (ARM ARM).
-
-Such hwcaps are described below in the form::
-
- Functionality implied by idreg.field == val.
-
-Such hwcaps indicate the availability of functionality that the ARM ARM
-defines as being present when idreg.field has value val, but do not
-indicate that idreg.field is precisely equal to val, nor do they
-indicate the absence of functionality implied by other values of
-idreg.field.
-
-Other hwcaps may indicate the presence of features which cannot be
-described by ID registers alone. These may be described without
-reference to ID registers, and may refer to other documentation.

-==============================
-Memory Layout on AArch64 Linux
-==============================
-
-Author: Catalin Marinas <catalin.marinas@arm.com>
-
-This document describes the virtual memory layout used by the AArch64
-Linux kernel. The architecture allows up to 4 levels of translation
-tables with a 4KB page size and up to 3 levels with a 64KB page size.
-
-AArch64 Linux uses either 3 levels or 4 levels of translation tables
-with the 4KB page configuration, allowing 39-bit (512GB) or 48-bit
-(256TB) virtual addresses, respectively, for both user and kernel. With
-64KB pages, only 2 levels of translation tables, allowing 42-bit (4TB)
-virtual address, are used but the memory layout is the same.
-
-ARMv8.2 adds optional support for Large Virtual Address space. This is
-only available when running with a 64KB page size and expands the
-number of descriptors in the first level of translation.
-
-User addresses have bits 63:48 set to 0 while the kernel addresses have
-the same bits set to 1. TTBRx selection is given by bit 63 of the
-virtual address. The swapper_pg_dir contains only kernel (global)
-mappings while the user pgd contains only user (non-global) mappings.
-The swapper_pg_dir address is written to TTBR1 and never written to
-TTBR0.

-
-When using KVM without the Virtualization Host Extensions, the
-hypervisor maps kernel pages in EL2 at a fixed (and potentially
-random) offset from the linear mapping. See the kern_hyp_va macro and
-kvm_update_va_mask function for more details. MMIO devices such as
-GICv2 gets mapped next to the HYP idmap page, as do vectors when
-ARM64_SPECTRE_V3A is enabled for particular CPUs.
-
-When using KVM with the Virtualization Host Extensions, no additional
-mappings are created, since the host kernel runs directly in EL2.
-
-52-bit VA support in the kernel
--------------------------------
-If the ARMv8.2-LVA optional feature is present, and we are running
-with a 64KB page size; then it is possible to use 52-bits of address
-space for both userspace and kernel addresses. However, any kernel
-binary that supports 52-bit must also be able to fall back to 48-bit
-at early boot time if the hardware feature is not present.
-
-This fallback mechanism necessitates the kernel .text to be in the
-higher addresses such that they are invariant to 48/52-bit VAs. Due
-to the kasan shadow being a fraction of the entire kernel VA space,
-the end of the kasan shadow must also be in the higher half of the
-kernel VA space for both 48/52-bit. (Switching from 48-bit to 52-bit,
-the end of the kasan shadow is invariant and dependent on ~0UL,
-whilst the start address will "grow" towards the lower addresses).
-
-In order to optimise phys_to_virt and virt_to_phys, the PAGE_OFFSET
-is kept constant at 0xFFF0000000000000 (corresponding to 52-bit),
-this obviates the need for an extra variable read. The physvirt
-offset and vmemmap offsets are computed at early boot to enable
-this logic.
-
-As a single binary will need to support both 48-bit and 52-bit VA
-spaces, the VMEMMAP must be sized large enough for 52-bit VAs and
-also must be sized large enough to accommodate a fixed PAGE_OFFSET.
-
-Most code in the kernel should not need to consider the VA_BITS, for
-code that does need to know the VA size the variables are
-defined as follows:
-
-VA_BITS constant the *maximum* VA space size
-
-VA_BITS_MIN constant the *minimum* VA space size
-
-vabits_actual variable the *actual* VA space size
-
-
-Maximum and minimum sizes can be useful to ensure that buffers are
-sized large enough or that addresses are positioned close enough for
-the "worst" case.
-
-52-bit userspace VAs
---------------------
-To maintain compatibility with software that relies on the ARMv8.0
-VA space maximum size of 48-bits, the kernel will, by default,
-return virtual addresses to userspace from a 48-bit range.
-
-Software can "opt-in" to receiving VAs from a 52-bit space by
-specifying an mmap hint parameter that is larger than 48-bit.
-
-For example:
-
-.. code-block:: c
-
- maybe_high_address = mmap(~0UL, size, prot, flags,...);
-
-It is also possible to build a debug kernel that returns addresses
-from a 52-bit space by enabling the following kernel config options:
-

-Perf Event Attributes
-=====================
-
-:Author: Andrew Murray <andrew.murray@arm.com>
-:Date: 2019-03-06
-
-exclude_user
-------------
-
-This attribute excludes userspace.
-
-Userspace always runs at EL0 and thus this attribute will exclude EL0.
-
-
-exclude_kernel
---------------
-
-This attribute excludes the kernel.
-
-The kernel runs at EL2 with VHE and EL1 without. Guest kernels always run
-at EL1.
-
-For the host this attribute will exclude EL1 and additionally EL2 on a VHE
-system.
-
-For the guest this attribute will exclude EL1. Please note that EL2 is
-never counted within a guest.
-
-
-exclude_hv
-----------
-
-This attribute excludes the hypervisor.
-
-For a VHE host this attribute is ignored as we consider the host kernel to
-be the hypervisor.
-
-For a non-VHE host this attribute will exclude EL2 as we consider the
-hypervisor to be any code that runs at EL2 which is predominantly used for
-guest/host transitions.
-
-For the guest this attribute has no effect. Please note that EL2 is
-never counted within a guest.
-
-
-exclude_host / exclude_guest
-----------------------------
-
-These attributes exclude the KVM host and guest, respectively.
-
-The KVM host may run at EL0 (userspace), EL1 (non-VHE kernel) and EL2 (VHE
-kernel or non-VHE hypervisor).
-
-The KVM guest may run at EL0 (userspace) and EL1 (kernel).
-
-Due to the overlapping exception levels between host and guests we cannot
-exclusively rely on the PMU's hardware exception filtering - therefore we
-must enable/disable counting on the entry and exit to the guest. This is
-performed differently on VHE and non-VHE systems.
-
-For non-VHE systems we exclude EL2 for exclude_host - upon entering and
-exiting the guest we disable/enable the event as appropriate based on the
-exclude_host and exclude_guest attributes.
-
-For VHE systems we exclude EL1 for exclude_guest and exclude both EL0,EL2
-for exclude_host. Upon entering and exiting the guest we modify the event
-to include/exclude EL0 as appropriate based on the exclude_host and
-exclude_guest attributes.
-
-The statements above also apply when these attributes are used within a
-non-VHE guest however please note that EL2 is never counted within a guest.
-
-
-Accuracy
---------
-
-On non-VHE hosts we enable/disable counters on the entry/exit of host/guest
-transition at EL2 - however there is a period of time between
-enabling/disabling the counters and entering/exiting the guest. We are
-able to eliminate counters counting host events on the boundaries of guest
-entry/exit when counting guest events by filtering out EL2 for
-exclude_host. However when using !exclude_hv there is a small blackout
-window at the guest entry/exit where host events are not captured.
-
-On VHE systems there are no blackout windows.
-
-Perf Userspace PMU Hardware Counter Access
-==========================================
-
-Overview
---------
-The perf userspace tool relies on the PMU to monitor events. It offers an
-abstraction layer over the hardware counters since the underlying
-implementation is cpu-dependent.
-Arm64 allows userspace tools to have access to the registers storing the
-hardware counters' values directly.
-
-This targets specifically self-monitoring tasks in order to reduce the overhead
-by directly accessing the registers without having to go through the kernel.
-
-How-to
-------
-The focus is set on the armv8 PMUv3 which makes sure that the access to the pmu
-registers is enabled and that the userspace has access to the relevant
-information in order to use them.
-
-In order to have access to the hardware counters, the global sysctl
-kernel/perf_user_access must first be enabled:
-
-.. code-block:: sh
-
- echo 1 > /proc/sys/kernel/perf_user_access
-
-It is necessary to open the event using the perf tool interface with config1:1
-attr bit set: the sys_perf_event_open syscall returns a fd which can
-subsequently be used with the mmap syscall in order to retrieve a page of memory
-containing information about the event. The PMU driver uses this page to expose
-to the user the hardware counter's index and other necessary data. Using this
-index enables the user to access the PMU registers using the `mrs` instruction.
-Access to the PMU registers is only valid while the sequence lock is unchanged.
-In particular, the PMSELR_EL0 register is zeroed each time the sequence lock is
-changed.
-
-The userspace access is supported in libperf using the perf_evsel__mmap()
-and perf_evsel__read() functions. See `tools/lib/perf/tests/test-evsel.c`_ for
-an example.
-
-About heterogeneous systems
----------------------------
-On heterogeneous systems such as big.LITTLE, userspace PMU counter access can
-only be enabled when the tasks are pinned to a homogeneous subset of cores and
-the corresponding PMU instance is opened by specifying the 'type' attribute.
-The use of generic event types is not supported in this case.
-
-Have a look at `tools/perf/arch/arm64/tests/user-events.c`_ for an example. It
-can be run using the perf tool to check that the access to the registers works
-correctly from userspace:
-
-.. code-block:: sh
-
- perf test -v user
-
-About chained events and counter sizes
---------------------------------------
-The user can request either a 32-bit (config1:0 == 0) or 64-bit (config1:0 == 1)
-counter along with userspace access. The sys_perf_event_open syscall will fail
-if a 64-bit counter is requested and the hardware doesn't support 64-bit
-counters. Chained events are not supported in conjunction with userspace counter
-access. If a 32-bit counter is requested on hardware with 64-bit counters, then
-userspace must treat the upper 32-bits read from the counter as UNKNOWN. The
-'pmc_width' field in the user page will indicate the valid width of the counter
-and should be used to mask the upper bits as needed.

-=======================================
-Silicon Errata and Software Workarounds
-=======================================
-
-Author: Will Deacon <will.deacon@arm.com>
-
-Date : 27 November 2015
-
-It is an unfortunate fact of life that hardware is often produced with
-so-called "errata", which can cause it to deviate from the architecture
-under specific circumstances. For hardware produced by ARM, these
-errata are broadly classified into the following categories:
-
- ========== ========================================================
- Category A A critical error without a viable workaround.
- Category B A significant or critical error with an acceptable
- workaround.
- Category C A minor error that is not expected to occur under normal
- operation.
- ========== ========================================================
-
-For more information, consult one of the "Software Developers Errata
-Notice" documents available on infocenter.arm.com (registration
-required).
-
-As far as Linux is concerned, Category B errata may require some special
-treatment in the operating system. For example, avoiding a particular
-sequence of code, or configuring the processor in a particular way. A
-less common situation may require similar actions in order to declassify
-a Category A erratum into a Category C erratum. These are collectively
-known as "software workarounds" and are only required in the minority of
-cases (e.g. those cases that both require a non-secure workaround *and*
-can be triggered by Linux).
-
-For software workarounds that may adversely impact systems unaffected by
-the erratum in question, a Kconfig entry is added under "Kernel
-Features" -> "ARM errata workarounds via the alternatives framework".
-These are enabled by default and patched in at runtime when an affected
-CPU is detected. For less-intrusive workarounds, a Kconfig option is not
-available and the code is structured (preferably with a comment) in such
-a way that the erratum will not be hit.
-
-This approach can make it slightly onerous to determine exactly which
-errata are worked around in an arbitrary kernel source tree, so this
-file acts as a registry of software workarounds in the Linux Kernel and
-will be updated when new workarounds are committed and backported to
-stable kernels.

+Hardware-wrapped keys
+=====================
+
+Motivation and threat model
+---------------------------
+
+Linux storage encryption (dm-crypt, fscrypt, eCryptfs, etc.) traditionally
+relies on the raw encryption key(s) being present in kernel memory so that the
+encryption can be performed. This traditionally isn't seen as a problem because
+the key(s) won't be present during an offline attack, which is the main type of
+attack that storage encryption is intended to protect from.
+
+However, there is an increasing desire to also protect users' data from other
+types of attacks (to the extent possible), including:
+
+- Cold boot attacks, where an attacker with physical access to a system suddenly
+ powers it off, then immediately dumps the system memory to extract recently
+ in-use encryption keys, then uses these keys to decrypt user data on-disk.
+
+- Online attacks where the attacker is able to read kernel memory without fully
+ compromising the system, followed by an offline attack where any extracted
+ keys can be used to decrypt user data on-disk. An example of such an online
+ attack would be if the attacker is able to run some code on the system that
+ exploits a Meltdown-like vulnerability but is unable to escalate privileges.
+
+- Online attacks where the attacker fully compromises the system, but their data
+ exfiltration is significantly time-limited and/or bandwidth-limited, so in
+ order to completely exfiltrate the data they need to extract the encryption
+ keys to use in a later offline attack.
+
+Hardware-wrapped keys are a feature of inline encryption hardware that is
+designed to protect users' data from the above attacks (to the extent possible),
+without introducing limitations such as a maximum number of keys.
+
+Note that it is impossible to **fully** protect users' data from these attacks.
+Even in the attacks where the attacker "just" gets read access to kernel memory,
+they can still extract any user data that is present in memory, including
+plaintext pagecache pages of encrypted files. The focus here is just on
+protecting the encryption keys, as those instantly give access to **all** user
+data in any following offline attack, rather than just some of it (where which
+data is included in that "some" might not be controlled by the attacker).
+
+Solution overview
+-----------------
+
+Inline encryption hardware typically has "keyslots" into which software can
+program keys for the hardware to use; the contents of keyslots typically can't
+be read back by software. As such, the above security goals could be achieved
+if the kernel simply erased its copy of the key(s) after programming them into
+keyslot(s) and thereafter only referred to them via keyslot number.
+
+However, that naive approach runs into a couple problems:
+
+- It limits the number of unlocked keys to the number of keyslots, which
+ typically is a small number. In cases where there is only one encryption key
+ system-wide (e.g., a full-disk encryption key), that can be tolerable.
+ However, in general there can be many logged-in users with many different
+ keys, and/or many running applications with application-specific encrypted
+ storage areas. This is especially true if file-based encryption (e.g.
+ fscrypt) is being used.
+
+- Inline crypto engines typically lose the contents of their keyslots if the
+ storage controller (usually UFS or eMMC) is reset. Resetting the storage
+ controller is a standard error recovery procedure that is executed if certain
+ types of storage errors occur, and such errors can occur at any time.
+ Therefore, when inline crypto is being used, the operating system must always
+ be ready to reprogram the keyslots without user intervention.
+
+Thus, it is important for the kernel to still have a way to "remind" the
+hardware about a key, without actually having the raw key itself.
+
+Somewhat less importantly, it is also desirable that the raw keys are never
+visible to software at all, even while being initially unlocked. This would
+ensure that a read-only compromise of system memory will never allow a key to be
+extracted to be used off-system, even if it occurs when a key is being unlocked.
+
+To solve all these problems, some vendors of inline encryption hardware have
+made their hardware support *hardware-wrapped keys*. Hardware-wrapped keys
+are encrypted keys that can only be unwrapped (decrypted) and used by hardware
+-- either by the inline encryption hardware itself, or by a dedicated hardware
+block that can directly provision keys to the inline encryption hardware.
+
+(We refer to them as "hardware-wrapped keys" rather than simply "wrapped keys"
+to add some clarity in cases where there could be other types of wrapped keys,
+such as in file-based encryption. Key wrapping is a commonly used technique.)
+
+The key which wraps (encrypts) hardware-wrapped keys is a hardware-internal key
+that is never exposed to software; it is either a persistent key (a "long-term
+wrapping key") or a per-boot key (an "ephemeral wrapping key"). The long-term
+wrapped form of the key is what is initially unlocked, but it is erased from
+memory as soon as it is converted into an ephemerally-wrapped key. In-use
+hardware-wrapped keys are always ephemerally-wrapped, not long-term wrapped.
+
+As inline encryption hardware can only be used to encrypt/decrypt data on-disk,
+the hardware also includes a level of indirection; it doesn't use the unwrapped
+key directly for inline encryption, but rather derives both an inline encryption
+key and a "software secret" from it. Software can use the "software secret" for
+tasks that can't use the inline encryption hardware, such as filenames
+encryption. The software secret is not protected from memory compromise.
+
+Key hierarchy
+-------------
+
+Here is the key hierarchy for a hardware-wrapped key::
+
+ Hardware-wrapped key
+ |
+ |
+ <Hardware KDF>
+ |
+ -----------------------------
+ | |
+ Inline encryption key Software secret
+
+The components are:
+
+- *Hardware-wrapped key*: a key for the hardware's KDF (Key Derivation
+ Function), in ephemerally-wrapped form. The key wrapping algorithm is a
+ hardware implementation detail that doesn't impact kernel operation, but a
+ strong authenticated encryption algorithm such as AES-256-GCM is recommended.
+
+- *Hardware KDF*: a KDF (Key Derivation Function) which the hardware uses to
+ derive subkeys after unwrapping the wrapped key. The hardware's choice of KDF
+ doesn't impact kernel operation, but it does need to be known for testing
+ purposes, and it's also assumed to have at least a 256-bit security strength.
+ All known hardware uses the SP800-108 KDF in Counter Mode with AES-256-CMAC,
+ with a particular choice of labels and contexts; new hardware should use this
+ already-vetted KDF.
+
+- *Inline encryption key*: a derived key which the hardware directly provisions
+ to a keyslot of the inline encryption hardware, without exposing it to
+ software. In all known hardware, this will always be an AES-256-XTS key.
+ However, in principle other encryption algorithms could be supported too.
+ Hardware must derive distinct subkeys for each supported encryption algorithm.
+
+- *Software secret*: a derived key which the hardware returns to software so
+ that software can use it for cryptographic tasks that can't use inline
+ encryption. This value is cryptographically isolated from the inline
+ encryption key, i.e. knowing one doesn't reveal the other. (The KDF ensures
+ this.) Currently, the software secret is always 32 bytes and thus is suitable
+ for cryptographic applications that require up to a 256-bit security strength.
+ Some use cases (e.g. full-disk encryption) won't require the software secret.
+
+Example: in the case of fscrypt, the fscrypt master key (the key that protects a
+particular set of encrypted directories) is made hardware-wrapped. The inline
+encryption key is used as the file contents encryption key, while the software
+secret (rather than the master key directly) is used to key fscrypt's KDF
+(HKDF-SHA512) to derive other subkeys such as filenames encryption keys.
+
+Note that currently this design assumes a single inline encryption key per
+hardware-wrapped key, without any further key derivation. Thus, in the case of
+fscrypt, currently hardware-wrapped keys are only compatible with the "inline
+encryption optimized" settings, which use one file contents encryption key per
+encryption policy rather than one per file. This design could be extended to
+make the hardware derive per-file keys using per-file nonces passed down the
+storage stack, and in fact some hardware already supports this; future work is
+planned to remove this limitation by adding the corresponding kernel support.
+
+Kernel support
+--------------
+
+The inline encryption support of the kernel's block layer ("blk-crypto") has
+been extended to support hardware-wrapped keys as an alternative to raw keys,
+when hardware support is available. This works in the following way:
+
+- A ``key_types_supported`` field is added to the crypto capabilities in
+ ``struct blk_crypto_profile``. This allows device drivers to declare that
+ they support raw keys, hardware-wrapped keys, or both.
+
+- ``struct blk_crypto_key`` can now contain a hardware-wrapped key as an
+ alternative to a raw key; a ``key_type`` field is added to
+ ``struct blk_crypto_config`` to distinguish between the different key types.
+ This allows users of blk-crypto to en/decrypt data using a hardware-wrapped
+ key in a way very similar to using a raw key.
+
+- A new method ``blk_crypto_ll_ops::derive_sw_secret`` is added. Device drivers
+ that support hardware-wrapped keys must implement this method. Users of
+ blk-crypto can call ``blk_crypto_derive_sw_secret()`` to access this method.
+
+- The programming and eviction of hardware-wrapped keys happens via
+ ``blk_crypto_ll_ops::keyslot_program`` and
+ ``blk_crypto_ll_ops::keyslot_evict``, just like it does for raw keys. If a
+ driver supports hardware-wrapped keys, then it must handle hardware-wrapped
+ keys being passed to these methods.
+
+blk-crypto-fallback doesn't support hardware-wrapped keys. Therefore,
+hardware-wrapped keys can only be used with actual inline encryption hardware.
+
+All the above deals with hardware-wrapped keys in ephemerally-wrapped form only.
+To get such keys in the first place, new block device ioctls have been added to
+provide a generic interface to creating and preparing such keys:
+
+- ``BLKCRYPTOIMPORTKEY`` converts a raw key to long-term wrapped form. It takes
+ in a pointer to a ``struct blk_crypto_import_key_arg``. The caller must set
+ ``raw_key_ptr`` and ``raw_key_size`` to the pointer and size (in bytes) of the
+ raw key to import. On success, ``BLKCRYPTOIMPORTKEY`` returns 0 and writes
+ the resulting long-term wrapped key blob to the buffer pointed to by
+ ``lt_key_ptr``, which is of maximum size ``lt_key_size``. It also updates
+ ``lt_key_size`` to be the actual size of the key. On failure, it returns -1
+ and sets errno. An errno of ``EOPNOTSUPP`` indicates that the block device
+ does not support hardware-wrapped keys. An errno of ``EOVERFLOW`` indicates
+ that the output buffer did not have enough space for the key blob.
+
+- ``BLKCRYPTOGENERATEKEY`` is like ``BLKCRYPTOIMPORTKEY``, but it has the
+ hardware generate the key instead of importing one. It takes in a pointer to
+ a ``struct blk_crypto_generate_key_arg``.
+
+- ``BLKCRYPTOPREPAREKEY`` converts a key from long-term wrapped form to
+ ephemerally-wrapped form. It takes in a pointer to a ``struct
+ blk_crypto_prepare_key_arg``. The caller must set ``lt_key_ptr`` and
+ ``lt_key_size`` to the pointer and size (in bytes) of the long-term wrapped
+ key blob to convert. On success, ``BLKCRYPTOPREPAREKEY`` returns 0 and writes
+ the resulting ephemerally-wrapped key blob to the buffer pointed to by
+ ``eph_key_ptr``, which is of maximum size ``eph_key_size``. It also updates
+ ``eph_key_size`` to be the actual size of the key. On failure, it returns -1
+ and sets errno. Errno values of ``EOPNOTSUPP`` and ``EOVERFLOW`` mean the
+ same as they do for ``BLKCRYPTOIMPORTKEY``. An errno of ``EBADMSG`` indicates
+ that the long-term wrapped key is invalid.
+
+Userspace needs to use either ``BLKCRYPTOIMPORTKEY`` or ``BLKCRYPTOGENERATEKEY``
+once to create a key, and then ``BLKCRYPTOPREPAREKEY`` each time the key is
+unlocked and added to the kernel. Note that these ioctls have no relevance for
+raw keys; they are only for hardware-wrapped keys.
+
+Testability
+-----------
+
+Both the hardware KDF and the inline encryption itself are well-defined
+algorithms that don't depend on any secrets other than the unwrapped key.
+Therefore, if the unwrapped key is known to software, these algorithms can be
+reproduced in software in order to verify the ciphertext that is written to disk
+by the inline encryption hardware.
+
+However, the unwrapped key will only be known to software for testing if the
+"import" functionality is used. Proper testing is not possible in the
+"generate" case where the hardware generates the key itself. The correct
+operation of the "generate" mode thus relies on the security and correctness of
+the hardware RNG and its use to generate the key, as well as the testing of the
+"import" mode as that should cover all parts other than the key generation.
+
+For an example of a test that verifies the ciphertext written to disk in the
+"import" mode, see the fscrypt hardware-wrapped key tests in xfstests, or
+`Android's vts_kernel_encryption_test
+<https://android.googlesource.com/platform/test/vts-testcase/kernel/+/refs/heads/main/encryption/>`_.

Zero copy
---------
-Zero copy is a generic requirement for nbd, fuse or similar drivers. A
-problem [#xiaoguang]_ Xiaoguang mentioned is that pages mapped to userspace
-can't be remapped any more in kernel with existing mm interfaces. This can
-occurs when destining direct IO to ``/dev/ublkb*``. Also, he reported that
-big requests (IO size >= 256 KB) may benefit a lot from zero copy.
+ublk zero copy relies on io_uring's fixed kernel buffer, which provides
+two APIs: `io_buffer_register_bvec()` and `io_buffer_unregister_bvec`.
+
+ublk adds IO command of `UBLK_IO_REGISTER_IO_BUF` to call
+`io_buffer_register_bvec()` for ublk server to register client request
+buffer into io_uring buffer table, then ublk server can submit io_uring
+IOs with the registered buffer index. IO command of `UBLK_IO_UNREGISTER_IO_BUF`
+calls `io_buffer_unregister_bvec()` to unregister the buffer, which is
+guaranteed to be live between calling `io_buffer_register_bvec()` and
+`io_buffer_unregister_bvec()`. Any io_uring operation which supports this
+kind of kernel buffer will grab one reference of the buffer until the
+operation is completed.
+
+ublk server implementing zero copy or user copy has to be CAP_SYS_ADMIN and
+be trusted, because it is ublk server's responsibility to make sure IO buffer
+filled with data for handling read command, and ublk server has to return
+correct result to ublk driver when handling READ command, and the result
+has to match with how many bytes filled to the IO buffer. Otherwise,
+uninitialized kernel IO buffer will be exposed to client application.
+
+ublk server needs to align the parameter of `struct ublk_param_dma_align`
+with backend for zero copy to work correctly.
+
+For reaching best IO performance, ublk server should align its segment
+parameter of `struct ublk_param_segment` with backend for avoiding
+unnecessary IO split, which usually hurts io_uring performance.
+
+Auto Buffer Registration
+------------------------
+
+The ``UBLK_F_AUTO_BUF_REG`` feature automatically handles buffer registration
+and unregistration for I/O requests, which simplifies the buffer management
+process and reduces overhead in the ublk server implementation.
+
+This is another feature flag for using zero copy, and it is compatible with
+``UBLK_F_SUPPORT_ZERO_COPY``.
+
+Feature Overview
+~~~~~~~~~~~~~~~~
+
+This feature automatically registers request buffers to the io_uring context
+before delivering I/O commands to the ublk server and unregisters them when
+completing I/O commands. This eliminates the need for manual buffer
+registration/unregistration via ``UBLK_IO_REGISTER_IO_BUF`` and
+``UBLK_IO_UNREGISTER_IO_BUF`` commands, then IO handling in ublk server
+can avoid dependency on the two uring_cmd operations.
+
+IOs can't be issued concurrently to io_uring if there is any dependency
+among these IOs. So this way not only simplifies ublk server implementation,
+but also makes concurrent IO handling becomes possible by removing the
+dependency on buffer registration & unregistration commands.
+
+Usage Requirements
+~~~~~~~~~~~~~~~~~~
+1. The ublk server must create a sparse buffer table on the same ``io_ring_ctx``
+ used for ``UBLK_IO_FETCH_REQ`` and ``UBLK_IO_COMMIT_AND_FETCH_REQ``. If
+ uring_cmd is issued on a different ``io_ring_ctx``, manual buffer
+ unregistration is required.
+
+2. Buffer registration data must be passed via uring_cmd's ``sqe->addr`` with the
+ following structure::
+
+ struct ublk_auto_buf_reg {
+ __u16 index; /* Buffer index for registration */
+ __u8 flags; /* Registration flags */
+ __u8 reserved0; /* Reserved for future use */
+ __u32 reserved1; /* Reserved for future use */
+ };
+
+ ublk_auto_buf_reg_to_sqe_addr() is for converting the above structure into
+ ``sqe->addr``.
+
+3. All reserved fields in ``ublk_auto_buf_reg`` must be zeroed.
+
+4. Optional flags can be passed via ``ublk_auto_buf_reg.flags``.
+
+Fallback Behavior
+~~~~~~~~~~~~~~~~~
+
+If auto buffer registration fails:
+
+1. When ``UBLK_AUTO_BUF_REG_FALLBACK`` is enabled:
+
+ - The uring_cmd is completed
+ - ``UBLK_IO_F_NEED_REG_BUF`` is set in ``ublksrv_io_desc.op_flags``
+ - The ublk server must manually deal with the failure, such as, register
+ the buffer manually, or using user copy feature for retrieving the data
+ for handling ublk IO
+
+2. If fallback is not enabled:
+
+ - The ublk I/O request fails silently
+ - The uring_cmd won't be completed
+
+Limitations
+~~~~~~~~~~~
+
+- Requires same ``io_ring_ctx`` for all operations
+- May require manual buffer management in fallback cases
+- io_ring_ctx buffer table has a max size of 16K, which may not be enough
+ in case that too many ublk devices are handled by this single io_ring_ctx
+ and each one has very large queue depth

BPF Iterators
=============
+--------
+Overview
+--------
+
+BPF supports two separate entities collectively known as "BPF iterators": BPF
+iterator *program type* and *open-coded* BPF iterators. The former is
+a stand-alone BPF program type which, when attached and activated by user,
+will be called once for each entity (task_struct, cgroup, etc) that is being
+iterated. The latter is a set of BPF-side APIs implementing iterator
+functionality and available across multiple BPF program types. Open-coded
+iterators provide similar functionality to BPF iterator programs, but gives
+more flexibility and control to all other BPF program types. BPF iterator
+programs, on the other hand, can be used to implement anonymous or BPF
+FS-mounted special files, whose contents are generated by attached BPF iterator
+program, backed by seq_file functionality. Both are useful depending on
+specific needs.
+
+When adding a new BPF iterator program, it is expected that similar
+functionality will be added as open-coded iterator for maximum flexibility.
+It's also expected that iteration logic and code will be maximally shared and
+reused between two iterator API surfaces.
-----------
-Motivation
-----------
+------------------------
+Open-coded BPF Iterators
+------------------------
+
+Open-coded BPF iterators are implemented as tightly-coupled trios of kfuncs
+(constructor, next element fetch, destructor) and iterator-specific type
+describing on-the-stack iterator state, which is guaranteed by the BPF
+verifier to not be tampered with outside of the corresponding
+constructor/destructor/next APIs.
+
+Each kind of open-coded BPF iterator has its own associated
+struct bpf_iter_<type>, where <type> denotes a specific type of iterator.
+bpf_iter_<type> state needs to live on BPF program stack, so make sure it's
+small enough to fit on BPF stack. For performance reasons its best to avoid
+dynamic memory allocation for iterator state and size the state struct big
+enough to fit everything necessary. But if necessary, dynamic memory
+allocation is a way to bypass BPF stack limitations. Note, state struct size
+is part of iterator's user-visible API, so changing it will break backwards
+compatibility, so be deliberate about designing it.
+
+All kfuncs (constructor, next, destructor) have to be named consistently as
+bpf_iter_<type>_{new,next,destroy}(), respectively. <type> represents iterator
+type, and iterator state should be represented as a matching
+`struct bpf_iter_<type>` state type. Also, all iter kfuncs should have
+a pointer to this `struct bpf_iter_<type>` as the very first argument.
+
+Additionally:
+ - Constructor, i.e., `bpf_iter_<type>_new()`, can have arbitrary extra
+ number of arguments. Return type is not enforced either.
+ - Next method, i.e., `bpf_iter_<type>_next()`, has to return a pointer
+ type and should have exactly one argument: `struct bpf_iter_<type> *`
+ (const/volatile/restrict and typedefs are ignored).
+ - Destructor, i.e., `bpf_iter_<type>_destroy()`, should return void and
+ should have exactly one argument, similar to the next method.
+ - `struct bpf_iter_<type>` size is enforced to be positive and
+ a multiple of 8 bytes (to fit stack slots correctly).
+
+Such strictness and consistency allows to build generic helpers abstracting
+important, but boilerplate, details to be able to use open-coded iterators
+effectively and ergonomically (see libbpf's bpf_for_each() macro). This is
+enforced at kfunc registration point by the kernel.
+
+Constructor/next/destructor implementation contract is as follows:
+ - constructor, `bpf_iter_<type>_new()`, always initializes iterator state on
+ the stack. If any of the input arguments are invalid, constructor should
+ make sure to still initialize it such that subsequent next() calls will
+ return NULL. I.e., on error, *return error and construct empty iterator*.
+ Constructor kfunc is marked with KF_ITER_NEW flag.
+
+ - next method, `bpf_iter_<type>_next()`, accepts pointer to iterator state
+ and produces an element. Next method should always return a pointer. The
+ contract between BPF verifier is that next method *guarantees* that it
+ will eventually return NULL when elements are exhausted. Once NULL is
+ returned, subsequent next calls *should keep returning NULL*. Next method
+ is marked with KF_ITER_NEXT (and should also have KF_RET_NULL as
+ NULL-returning kfunc, of course).
+
+ - destructor, `bpf_iter_<type>_destroy()`, is always called once. Even if
+ constructor failed or next returned nothing. Destructor frees up any
+ resources and marks stack space used by `struct bpf_iter_<type>` as usable
+ for something else. Destructor is marked with KF_ITER_DESTROY flag.
+
+Any open-coded BPF iterator implementation has to implement at least these
+three methods. It is enforced that for any given type of iterator only
+applicable constructor/destructor/next are callable. I.e., verifier ensures
+you can't pass number iterator state into, say, cgroup iterator's next method.
+
+From a 10,000-feet BPF verification point of view, next methods are the points
+of forking a verification state, which are conceptually similar to what
+verifier is doing when validating conditional jumps. Verifier is branching out
+`call bpf_iter_<type>_next` instruction and simulates two outcomes: NULL
+(iteration is done) and non-NULL (new element is returned). NULL is simulated
+first and is supposed to reach exit without looping. After that non-NULL case
+is validated and it either reaches exit (for trivial examples with no real
+loop), or reaches another `call bpf_iter_<type>_next` instruction with the
+state equivalent to already (partially) validated one. State equivalency at
+that point means we technically are going to be looping forever without
+"breaking out" out of established "state envelope" (i.e., subsequent
+iterations don't add any new knowledge or constraints to the verifier state,
+so running 1, 2, 10, or a million of them doesn't matter). But taking into

All the BTF ID lists and sets are compiled in the .BTF_ids section and
resolved during the linking phase of kernel build by ``resolve_btfids`` tool.
+4.4 .BTF.base section
+---------------------
+Split BTF - where the .BTF section only contains types not in the associated
+base .BTF section - is an extremely efficient way to encode type information
+for kernel modules, since they generally consist of a few module-specific
+types along with a large set of shared kernel types. The former are encoded
+in split BTF, while the latter are encoded in base BTF, resulting in more
+compact representations. A type in split BTF that refers to a type in
+base BTF refers to it using its base BTF ID, and split BTF IDs start
+at last_base_BTF_ID + 1.
+
+The downside of this approach however is that this makes the split BTF
+somewhat brittle - when the base BTF changes, base BTF ID references are
+no longer valid and the split BTF itself becomes useless. The role of the
+.BTF.base section is to make split BTF more resilient for cases where
+the base BTF may change, as is the case for kernel modules not built every
+time the kernel is for example. .BTF.base contains named base types; INTs,
+FLOATs, STRUCTs, UNIONs, ENUM[64]s and FWDs. INTs and FLOATs are fully
+described in .BTF.base sections, while composite types like structs
+and unions are not fully defined - the .BTF.base type simply serves as
+a description of the type the split BTF referred to, so structs/unions
+have 0 members in the .BTF.base section. ENUM[64]s are similarly recorded
+with 0 members. Any other types are added to the split BTF. This
+distillation process then leaves us with a .BTF.base section with
+such minimal descriptions of base types and .BTF split section which refers
+to those base types. Later, we can relocate the split BTF using both the
+information stored in the .BTF.base section and the new .BTF base; the type
+information in the .BTF.base section allows us to update the split BTF
+references to point at the corresponding new base BTF IDs.
+
+BTF relocation happens on kernel module load when a kernel module has a
+.BTF.base section, and libbpf also provides a btf__relocate() API to
+accomplish this.
+
+As an example consider the following base BTF::
+
+ [1] INT 'int' size=4 bits_offset=0 nr_bits=32 encoding=SIGNED
+ [2] STRUCT 'foo' size=8 vlen=2
+ 'f1' type_id=1 bits_offset=0
+ 'f2' type_id=1 bits_offset=32
+
+...and associated split BTF::
+
+ [3] PTR '(anon)' type_id=2
+
+i.e. split BTF describes a pointer to struct foo { int f1; int f2 };
+
+.BTF.base will consist of::
+
+ [1] INT 'int' size=4 bits_offset=0 nr_bits=32 encoding=SIGNED
+ [2] STRUCT 'foo' size=8 vlen=0
+
+If we relocate the split BTF later using the following new base BTF::
+
+ [1] INT 'long unsigned int' size=8 bits_offset=0 nr_bits=64 encoding=(none)
+ [2] INT 'int' size=4 bits_offset=0 nr_bits=32 encoding=SIGNED
+ [3] STRUCT 'foo' size=8 vlen=2
+ 'f1' type_id=2 bits_offset=0
+ 'f2' type_id=2 bits_offset=32
+
+...we can use our .BTF.base description to know that the split BTF reference
+is to struct foo, and relocation results in new split BTF::
+
+ [4] PTR '(anon)' type_id=3
+
+Note that we had to update BTF ID and start BTF ID for the split BTF.
+
+So we see how .BTF.base plays the role of facilitating later relocation,
+leading to more resilient split BTF.
+
+.BTF.base sections will be generated automatically for out-of-tree kernel module
+builds - i.e. where KBUILD_EXTMOD is set (as it would be for "make M=path/2/mod"
+cases). .BTF.base generation requires pahole support for the "distilled_base"
+BTF feature; this is available in pahole v1.28 and later.

-Instruction encoding
-====================
-
-eBPF has two instruction encodings:
-
-* the basic instruction encoding, which uses 64 bits to encode an instruction
-* the wide instruction encoding, which appends a second 64-bit immediate (i.e.,
- constant) value after the basic instruction for a total of 128 bits.
-
-The basic instruction encoding is as follows, where MSB and LSB mean the most significant
-bits and least significant bits, respectively:
-
-============= ======= ======= ======= ============
-32 bits (MSB) 16 bits 4 bits 4 bits 8 bits (LSB)
-============= ======= ======= ======= ============
-imm offset src_reg dst_reg opcode
-============= ======= ======= ======= ============
-
-**imm**
- signed integer immediate value
-
-**offset**
- signed integer offset used with pointer arithmetic
-
-**src_reg**
- the source register number (0-10), except where otherwise specified
- (`64-bit immediate instructions`_ reuse this field for other purposes)
-
-**dst_reg**
- destination register number (0-10)
-
-**opcode**
- operation to perform
-
-Note that most instructions do not use all of the fields.
-Unused fields shall be cleared to zero.
-
-As discussed below in `64-bit immediate instructions`_, a 64-bit immediate
-instruction uses a 64-bit immediate value that is constructed as follows.
-The 64 bits following the basic instruction contain a pseudo instruction
-using the same format but with opcode, dst_reg, src_reg, and offset all set to zero,
-and imm containing the high 32 bits of the immediate value.
-
-================= ==================
-64 bits (MSB) 64 bits (LSB)
-================= ==================
-basic instruction pseudo instruction
-================= ==================
-
-Thus the 64-bit immediate value is constructed as follows:
-
- imm64 = (next_imm << 32) | imm
-
-where 'next_imm' refers to the imm value of the pseudo instruction
-following the basic instruction.
-
-Instruction classes
--------------------
-
-The three LSB bits of the 'opcode' field store the instruction class:

-Arithmetic instructions
------------------------
-
-``BPF_ALU`` uses 32-bit wide operands while ``BPF_ALU64`` uses 64-bit wide operands for
-otherwise identical operations.
-The 'code' field encodes the operation as below, where 'src' and 'dst' refer
-to the values of the source and destination registers, respectively.
-
-======== ===== ==========================================================
-code value description
-======== ===== ==========================================================
-BPF_ADD 0x00 dst += src
-BPF_SUB 0x10 dst -= src
-BPF_MUL 0x20 dst \*= src
-BPF_DIV 0x30 dst = (src != 0) ? (dst / src) : 0
-BPF_OR 0x40 dst \|= src
-BPF_AND 0x50 dst &= src
-BPF_LSH 0x60 dst <<= src

-BPF_ARSH 0xc0 sign extending shift right
-BPF_END 0xd0 byte swap operations (see `Byte swap instructions`_ below)
-======== ===== ==========================================================
-
-Underflow and overflow are allowed during arithmetic operations, meaning
-the 64-bit or 32-bit value will wrap. If eBPF program execution would
-result in division by zero, the destination register is instead set to zero.
-If execution would result in modulo by zero, for ``BPF_ALU64`` the value of
-the destination register is unchanged whereas for ``BPF_ALU`` the upper
-32 bits of the destination register are zeroed.
-
-``BPF_ADD | BPF_X | BPF_ALU`` means::
-
- dst = (u32) ((u32) dst + (u32) src)
-
-where '(u32)' indicates that the upper 32 bits are zeroed.
-
-``BPF_ADD | BPF_X | BPF_ALU64`` means::
-
- dst = dst + src
-
-``BPF_XOR | BPF_K | BPF_ALU`` means::
-
- dst = (u32) dst ^ (u32) imm32
-
-``BPF_XOR | BPF_K | BPF_ALU64`` means::
-
- dst = dst ^ imm32
-
-Also note that the division and modulo operations are unsigned. Thus, for
-``BPF_ALU``, 'imm' is first interpreted as an unsigned 32-bit value, whereas
-for ``BPF_ALU64``, 'imm' is first sign extended to 64 bits and the result
-interpreted as an unsigned 64-bit value. There are no instructions for
-signed division or modulo.
-
-Byte swap instructions
-~~~~~~~~~~~~~~~~~~~~~~
-
-The byte swap instructions use an instruction class of ``BPF_ALU`` and a 4-bit
-'code' field of ``BPF_END``.
-
-The byte swap instructions operate on the destination register
-only and do not use a separate source register or immediate value.
-
-The 1-bit source operand field in the opcode is used to select what byte
-order the operation convert from or to:
-
-========= ===== =================================================
-source value description
-========= ===== =================================================
-BPF_TO_LE 0x00 convert between host byte order and little endian
-BPF_TO_BE 0x08 convert between host byte order and big endian
-========= ===== =================================================
-
-The 'imm' field encodes the width of the swap operations. The following widths
-are supported: 16, 32 and 64.
-
-Examples:
-
-``BPF_ALU | BPF_TO_LE | BPF_END`` with imm = 16 means::
-
- dst = htole16(dst)
-
-``BPF_ALU | BPF_TO_BE | BPF_END`` with imm = 64 means::
-
- dst = htobe64(dst)
-
-Jump instructions
------------------
-
-``BPF_JMP32`` uses 32-bit wide operands while ``BPF_JMP`` uses 64-bit wide operands for
-otherwise identical operations.
-The 'code' field encodes the operation as below:
-
-======== ===== ========================= ============

-======== ===== ========================= ============
-BPF_JA 0x00 PC += off BPF_JMP only
-BPF_JEQ 0x10 PC += off if dst == src

-BPF_JSET 0x40 PC += off if dst & src
-BPF_JNE 0x50 PC += off if dst != src

- BPF_H 0x08 half word (2 bytes)
- BPF_B 0x10 byte
- BPF_DW 0x18 double word (8 bytes)
- ============= ===== =====================
-
-Regular load and store operations
----------------------------------
-
-The ``BPF_MEM`` mode modifier is used to encode regular load and store
-instructions that transfer data between a register and memory.
-
-``BPF_MEM | <size> | BPF_STX`` means::
-
- *(size *) (dst + offset) = src
-
-``BPF_MEM | <size> | BPF_ST`` means::
-
- *(size *) (dst + offset) = imm32
-
-``BPF_MEM | <size> | BPF_LDX`` means::
-
- dst = *(size *) (src + offset)
-
-Where size is one of: ``BPF_B``, ``BPF_H``, ``BPF_W``, or ``BPF_DW``.
-
-Atomic operations
------------------
-
-Atomic operations are operations that operate on memory and can not be
-interrupted or corrupted by other access to the same memory region
-by other eBPF programs or means outside of this specification.
-
-All atomic operations supported by eBPF are encoded as store operations
-that use the ``BPF_ATOMIC`` mode modifier as follows:
-
-* ``BPF_ATOMIC | BPF_W | BPF_STX`` for 32-bit operations
-* ``BPF_ATOMIC | BPF_DW | BPF_STX`` for 64-bit operations
-* 8-bit and 16-bit wide atomic operations are not supported.
-
-The 'imm' field is used to encode the actual atomic operation.
-Simple atomic operation use a subset of the values defined to encode
-arithmetic operations in the 'imm' field to encode the atomic operation:
-
-======== ===== ===========
-imm value description
-======== ===== ===========
-BPF_ADD 0x00 atomic add
-BPF_OR 0x40 atomic or
-BPF_AND 0x50 atomic and
-BPF_XOR 0xa0 atomic xor
-======== ===== ===========
-
-
-``BPF_ATOMIC | BPF_W | BPF_STX`` with 'imm' = BPF_ADD means::
-
- *(u32 *)(dst + offset) += src
-
-``BPF_ATOMIC | BPF_DW | BPF_STX`` with 'imm' = BPF ADD means::
-
- *(u64 *)(dst + offset) += src
-
-In addition to the simple atomic operations, there also is a modifier and
-two complex atomic operations:
-
-=========== ================ ===========================
-imm value description
-=========== ================ ===========================
-BPF_FETCH 0x01 modifier: return old value
-BPF_XCHG 0xe0 | BPF_FETCH atomic exchange
-BPF_CMPXCHG 0xf0 | BPF_FETCH atomic compare and exchange
-=========== ================ ===========================
-
-The ``BPF_FETCH`` modifier is optional for simple atomic operations, and
-always set for the complex atomic operations. If the ``BPF_FETCH`` flag
-is set, then the operation also overwrites ``src`` with the value that
-was in memory before it was modified.
-
-The ``BPF_XCHG`` operation atomically exchanges ``src`` with the value
-addressed by ``dst + offset``.
-
-The ``BPF_CMPXCHG`` operation atomically compares the value addressed by
-``dst + offset`` with ``R0``. If they match, the value addressed by
-``dst + offset`` is replaced with ``src``. In either case, the
-value that was at ``dst + offset`` before the operation is zero-extended
-and loaded back to ``R0``.
-
-64-bit immediate instructions
------------------------------
-
-Instructions with the ``BPF_IMM`` 'mode' modifier use the wide instruction
-encoding for an extra imm64 value.
-
-There is currently only one such instruction.
-
-``BPF_LD | BPF_DW | BPF_IMM`` means::
-
- dst = imm64
-
-
-Legacy BPF Packet access instructions
--------------------------------------
-
-eBPF previously introduced special instructions for access to packet data that were
-carried over from classic BPF. However, these instructions are
-deprecated and should no longer be used.

+libbpf Overview
+===============
+
+libbpf is a C-based library containing a BPF loader that takes compiled BPF
+object files and prepares and loads them into the Linux kernel. libbpf takes the
+heavy lifting of loading, verifying, and attaching BPF programs to various
+kernel hooks, allowing BPF application developers to focus only on BPF program
+correctness and performance.
+
+The following are the high-level features supported by libbpf:
+
+* Provides high-level and low-level APIs for user space programs to interact
+ with BPF programs. The low-level APIs wrap all the bpf system call
+ functionality, which is useful when users need more fine-grained control
+ over the interactions between user space and BPF programs.
+* Provides overall support for the BPF object skeleton generated by bpftool.
+ The skeleton file simplifies the process for the user space programs to access
+ global variables and work with BPF programs.
+* Provides BPF-side APIS, including BPF helper definitions, BPF maps support,
+ and tracing helpers, allowing developers to simplify BPF code writing.
+* Supports BPF CO-RE mechanism, enabling BPF developers to write portable
+ BPF programs that can be compiled once and run across different kernel
+ versions.
+
+This document will delve into the above concepts in detail, providing a deeper
+understanding of the capabilities and advantages of libbpf and how it can help
+you develop BPF applications efficiently.
+
+BPF App Lifecycle and libbpf APIs
+==================================
+
+A BPF application consists of one or more BPF programs (either cooperating or
+completely independent), BPF maps, and global variables. The global
+variables are shared between all BPF programs, which allows them to cooperate on
+a common set of data. libbpf provides APIs that user space programs can use to
+manipulate the BPF programs by triggering different phases of a BPF application
+lifecycle.
+
+The following section provides a brief overview of each phase in the BPF life
+cycle:
+
+* **Open phase**: In this phase, libbpf parses the BPF
+ object file and discovers BPF maps, BPF programs, and global variables. After
+ a BPF app is opened, user space apps can make additional adjustments
+ (setting BPF program types, if necessary; pre-setting initial values for
+ global variables, etc.) before all the entities are created and loaded.
+
+* **Load phase**: In the load phase, libbpf creates BPF
+ maps, resolves various relocations, and verifies and loads BPF programs into
+ the kernel. At this point, libbpf validates all the parts of a BPF application
+ and loads the BPF program into the kernel, but no BPF program has yet been
+ executed. After the load phase, it’s possible to set up the initial BPF map
+ state without racing with the BPF program code execution.
+
+* **Attachment phase**: In this phase, libbpf
+ attaches BPF programs to various BPF hook points (e.g., tracepoints, kprobes,
+ cgroup hooks, network packet processing pipeline, etc.). During this
+ phase, BPF programs perform useful work such as processing
+ packets, or updating BPF maps and global variables that can be read from user
+ space.
+
+* **Tear down phase**: In the tear down phase,
+ libbpf detaches BPF programs and unloads them from the kernel. BPF maps are
+ destroyed, and all the resources used by the BPF app are freed.
+
+BPF Object Skeleton File
+========================
+
+BPF skeleton is an alternative interface to libbpf APIs for working with BPF
+objects. Skeleton code abstract away generic libbpf APIs to significantly
+simplify code for manipulating BPF programs from user space. Skeleton code
+includes a bytecode representation of the BPF object file, simplifying the
+process of distributing your BPF code. With BPF bytecode embedded, there are no
+extra files to deploy along with your application binary.
+
+You can generate the skeleton header file ``(.skel.h)`` for a specific object
+file by passing the BPF object to the bpftool. The generated BPF skeleton
+provides the following custom functions that correspond to the BPF lifecycle,
+each of them prefixed with the specific object name:
+
+* ``<name>__open()`` – creates and opens BPF application (``<name>`` stands for
+ the specific bpf object name)
+* ``<name>__load()`` – instantiates, loads,and verifies BPF application parts
+* ``<name>__attach()`` – attaches all auto-attachable BPF programs (it’s
+ optional, you can have more control by using libbpf APIs directly)
+* ``<name>__destroy()`` – detaches all BPF programs and
+ frees up all used resources
+
+Using the skeleton code is the recommended way to work with bpf programs. Keep
+in mind, BPF skeleton provides access to the underlying BPF object, so whatever
+was possible to do with generic libbpf APIs is still possible even when the BPF
+skeleton is used. It's an additive convenience feature, with no syscalls, and no
+cumbersome code.
+
+Other Advantages of Using Skeleton File
+---------------------------------------
+
+* BPF skeleton provides an interface for user space programs to work with BPF
+ global variables. The skeleton code memory maps global variables as a struct
+ into user space. The struct interface allows user space programs to initialize
+ BPF programs before the BPF load phase and fetch and update data from user
+ space afterward.
+
+* The ``skel.h`` file reflects the object file structure by listing out the
+ available maps, programs, etc. BPF skeleton provides direct access to all the
+ BPF maps and BPF programs as struct fields. This eliminates the need for
+ string-based lookups with ``bpf_object_find_map_by_name()`` and
+ ``bpf_object_find_program_by_name()`` APIs, reducing errors due to BPF source
+ code and user-space code getting out of sync.
+
+* The embedded bytecode representation of the object file ensures that the
+ skeleton and the BPF object file are always in sync.
+
+BPF Helpers
+===========
+
+libbpf provides BPF-side APIs that BPF programs can use to interact with the
+system. The BPF helpers definition allows developers to use them in BPF code as
+any other plain C function. For example, there are helper functions to print
+debugging messages, get the time since the system was booted, interact with BPF
+maps, manipulate network packets, etc.
+
+For a complete description of what the helpers do, the arguments they take, and
+the return value, see the `bpf-helpers
+<https://man7.org/linux/man-pages/man7/bpf-helpers.7.html>`_ man page.
+
+BPF CO-RE (Compile Once – Run Everywhere)
+=========================================
+
+BPF programs work in the kernel space and have access to kernel memory and data
+structures. One limitation that BPF applications come across is the lack of
+portability across different kernel versions and configurations. `BCC
+<https://github.com/iovisor/bcc/>`_ is one of the solutions for BPF
+portability. However, it comes with runtime overhead and a large binary size
+from embedding the compiler with the application.
+
+libbpf steps up the BPF program portability by supporting the BPF CO-RE concept.
+BPF CO-RE brings together BTF type information, libbpf, and the compiler to
+produce a single executable binary that you can run on multiple kernel versions
+and configurations.
+
+To make BPF programs portable libbpf relies on the BTF type information of the
+running kernel. Kernel also exposes this self-describing authoritative BTF
+information through ``sysfs`` at ``/sys/kernel/btf/vmlinux``.
+
+You can generate the BTF information for the running kernel with the following
+command:
+
+::
+
+ $ bpftool btf dump file /sys/kernel/btf/vmlinux format c > vmlinux.h
+
+The command generates a ``vmlinux.h`` header file with all kernel types
+(:doc:`BTF types <../btf>`) that the running kernel uses. Including
+``vmlinux.h`` in your BPF program eliminates dependency on system-wide kernel
+headers.
+
+libbpf enables portability of BPF programs by looking at the BPF program’s
+recorded BTF type and relocation information and matching them to BTF
+information (vmlinux) provided by the running kernel. libbpf then resolves and
+matches all the types and fields, and updates necessary offsets and other
+relocatable data to ensure that BPF program’s logic functions correctly for a
+specific kernel on the host. BPF CO-RE concept thus eliminates overhead
+associated with BPF development and allows developers to write portable BPF
+applications without modifications and runtime source code compilation on the
+target machine.
+
+The following code snippet shows how to read the parent field of a kernel
+``task_struct`` using BPF CO-RE and libbf. The basic helper to read a field in a
+CO-RE relocatable manner is ``bpf_core_read(dst, sz, src)``, which will read
+``sz`` bytes from the field referenced by ``src`` into the memory pointed to by
+``dst``.
+
+.. code-block:: C
+ :emphasize-lines: 6
+
+ //...
+ struct task_struct *task = (void *)bpf_get_current_task();
+ struct task_struct *parent_task;
+ int err;
+
+ err = bpf_core_read(&parent_task, sizeof(void *), &task->parent);
+ if (err) {
+ /* handle error */
+ }
+
+ /* parent_task contains the value of task->parent pointer */
+
+In the code snippet, we first get a pointer to the current ``task_struct`` using
+``bpf_get_current_task()``. We then use ``bpf_core_read()`` to read the parent
+field of task struct into the ``parent_task`` variable. ``bpf_core_read()`` is
+just like ``bpf_probe_read_kernel()`` BPF helper, except it records information
+about the field that should be relocated on the target kernel. i.e, if the
+``parent`` field gets shifted to a different offset within
+``struct task_struct`` due to some new field added in front of it, libbpf will
+automatically adjust the actual offset to the proper value.
+
+Getting Started with libbpf
+===========================
+
+Check out the `libbpf-bootstrap <https://github.com/libbpf/libbpf-bootstrap>`_
+repository with simple examples of using libbpf to build various BPF
+applications.
+
+See also `libbpf API documentation
+<https://libbpf.readthedocs.io/en/latest/api.html>`_.
+
+libbpf and Rust
+===============
+
+If you are building BPF applications in Rust, it is recommended to use the
+`Libbpf-rs <https://github.com/libbpf/libbpf-rs>`_ library instead of bindgen
+bindings directly to libbpf. Libbpf-rs wraps libbpf functionality in
+Rust-idiomatic interfaces and provides libbpf-cargo plugin to handle BPF code
+compilation and skeleton generation. Using Libbpf-rs will make building user
+space part of the BPF application easier. Note that the BPF program themselves
+must still be written in plain C.
+
+libbpf logging
+==============
+
+By default, libbpf logs informational and warning messages to stderr. The
+verbosity of these messages can be controlled by setting the environment
+variable LIBBPF_LOG_LEVEL to either warn, info, or debug. A custom log
+callback can be set using ``libbpf_set_print()``.

+
+=================
+CO-RE Relocations
+=================
+
+From object file point of view CO-RE mechanism is implemented as a set
+of CO-RE specific relocation records. These relocation records are not
+related to ELF relocations and are encoded in .BTF.ext section.
+See :ref:`Documentation/bpf/btf.rst <BTF_Ext_Section>` for more
+information on .BTF.ext structure.
+
+CO-RE relocations are applied to BPF instructions to update immediate
+or offset fields of the instruction at load time with information
+relevant for target kernel.
+
+Field to patch is selected basing on the instruction class:
+
+* For BPF_ALU, BPF_ALU64, BPF_LD `immediate` field is patched;
+* For BPF_LDX, BPF_STX, BPF_ST `offset` field is patched;
+* BPF_JMP, BPF_JMP32 instructions **should not** be patched.
+
+Relocation kinds
+================
+
+There are several kinds of CO-RE relocations that could be split in
+three groups:
+
+* Field-based - patch instruction with field related information, e.g.
+ change offset field of the BPF_LDX instruction to reflect offset
+ of a specific structure field in the target kernel.
+
+* Type-based - patch instruction with type related information, e.g.
+ change immediate field of the BPF_ALU move instruction to 0 or 1 to
+ reflect if specific type is present in the target kernel.
+
+* Enum-based - patch instruction with enum related information, e.g.
+ change immediate field of the BPF_LD_IMM64 instruction to reflect
+ value of a specific enum literal in the target kernel.
+
+The complete list of relocation kinds is represented by the following enum:
+
+.. code-block:: c
+
+ enum bpf_core_relo_kind {
+ BPF_CORE_FIELD_BYTE_OFFSET = 0, /* field byte offset */
+ BPF_CORE_FIELD_BYTE_SIZE = 1, /* field size in bytes */
+ BPF_CORE_FIELD_EXISTS = 2, /* field existence in target kernel */
+ BPF_CORE_FIELD_SIGNED = 3, /* field signedness (0 - unsigned, 1 - signed) */
+ BPF_CORE_FIELD_LSHIFT_U64 = 4, /* bitfield-specific left bitshift */
+ BPF_CORE_FIELD_RSHIFT_U64 = 5, /* bitfield-specific right bitshift */
+ BPF_CORE_TYPE_ID_LOCAL = 6, /* type ID in local BPF object */
+ BPF_CORE_TYPE_ID_TARGET = 7, /* type ID in target kernel */
+ BPF_CORE_TYPE_EXISTS = 8, /* type existence in target kernel */
+ BPF_CORE_TYPE_SIZE = 9, /* type size in bytes */
+ BPF_CORE_ENUMVAL_EXISTS = 10, /* enum value existence in target kernel */
+ BPF_CORE_ENUMVAL_VALUE = 11, /* enum value integer value */
+ BPF_CORE_TYPE_MATCHES = 12, /* type match in target kernel */
+ };
+
+Notes:
+
+* ``BPF_CORE_FIELD_LSHIFT_U64`` and ``BPF_CORE_FIELD_RSHIFT_U64`` are
+ supposed to be used to read bitfield values using the following
+ algorithm:
+
+ .. code-block:: c
+
+ // To read bitfield ``f`` from ``struct s``
+ is_signed = relo(s->f, BPF_CORE_FIELD_SIGNED)
+ off = relo(s->f, BPF_CORE_FIELD_BYTE_OFFSET)
+ sz = relo(s->f, BPF_CORE_FIELD_BYTE_SIZE)
+ l = relo(s->f, BPF_CORE_FIELD_LSHIFT_U64)
+ r = relo(s->f, BPF_CORE_FIELD_RSHIFT_U64)
+ // define ``v`` as signed or unsigned integer of size ``sz``
+ v = *({s|u}<sz> *)((void *)s + off)
+ v <<= l
+ v >>= r
+
+* The ``BPF_CORE_TYPE_MATCHES`` queries matching relation, defined as
+ follows:
+
+ * for integers: types match if size and signedness match;
+ * for arrays & pointers: target types are recursively matched;
+ * for structs & unions:
+
+ * local members need to exist in target with the same name;
+
+ * for each member we recursively check match unless it is already behind a
+ pointer, in which case we only check matching names and compatible kind;
+
+ * for enums:
+
+ * local variants have to have a match in target by symbolic name (but not
+ numeric value);
+
+ * size has to match (but enum may match enum64 and vice versa);
+
+ * for function pointers:
+
+ * number and position of arguments in local type has to match target;
+ * for each argument and the return value we recursively check match.
+
+CO-RE Relocation Record
+=======================
+
+Relocation record is encoded as the following structure:
+
+.. code-block:: c
+
+ struct bpf_core_relo {
+ __u32 insn_off;
+ __u32 type_id;
+ __u32 access_str_off;
+ enum bpf_core_relo_kind kind;
+ };
+
+* ``insn_off`` - instruction offset (in bytes) within a code section
+ associated with this relocation;
+
+* ``type_id`` - BTF type ID of the "root" (containing) entity of a
+ relocatable type or field;
+
+* ``access_str_off`` - offset into corresponding .BTF string section.
+ String interpretation depends on specific relocation kind:
+
+ * for field-based relocations, string encodes an accessed field using
+ a sequence of field and array indices, separated by colon (:). It's
+ conceptually very close to LLVM's `getelementptr <GEP_>`_ instruction's
+ arguments for identifying offset to a field. For example, consider the
+ following C code:
+
+ .. code-block:: c
+
+ struct sample {
+ int a;
+ int b;
+ struct { int c[10]; };
+ } __attribute__((preserve_access_index));
+ struct sample *s;
+
+ * Access to ``s[0].a`` would be encoded as ``0:0``:
+
+ * ``0``: first element of ``s`` (as if ``s`` is an array);
+ * ``0``: index of field ``a`` in ``struct sample``.
+
+ * Access to ``s->a`` would be encoded as ``0:0`` as well.
+ * Access to ``s->b`` would be encoded as ``0:1``:
+
+ * ``0``: first element of ``s``;
+ * ``1``: index of field ``b`` in ``struct sample``.
+
+ * Access to ``s[1].c[5]`` would be encoded as ``1:2:0:5``:
+
+ * ``1``: second element of ``s``;
+ * ``2``: index of anonymous structure field in ``struct sample``;
+ * ``0``: index of field ``c`` in anonymous structure;
+ * ``5``: access to array element #5.
+
+ * for type-based relocations, string is expected to be just "0";
+
+ * for enum value-based relocations, string contains an index of enum
+ value within its enum type;
+
+* ``kind`` - one of ``enum bpf_core_relo_kind``.

+=========
+
+This section of the document is targeted at Linux developers and describes
+aspects of the map implementations that are not considered stable ABI. The
+following details are subject to change in future versions of the kernel.
+
+``BPF_MAP_TYPE_LRU_HASH`` and variants
+--------------------------------------
+
+Updating elements in LRU maps may trigger eviction behaviour when the capacity
+of the map is reached. There are various steps that the update algorithm
+attempts in order to enforce the LRU property which have increasing impacts on
+other CPUs involved in the following operation attempts:
+
+- Attempt to use CPU-local state to batch operations
+- Attempt to fetch ``target_free`` free nodes from global lists
+- Attempt to pull any node from a global list and remove it from the hashmap
+- Attempt to pull any node from any CPU's list and remove it from the hashmap
+
+The number of nodes to borrow from the global list in a batch, ``target_free``,
+depends on the size of the map. Larger batch size reduces lock contention, but
+may also exhaust the global structure. The value is computed at map init to
+avoid exhaustion, by limiting aggregate reservation by all CPUs to half the map
+size. With a minimum of a single element and maximum budget of 128 at a time.
+
+This algorithm is described visually in the following diagram. See the
+description in commit 3a08c2fd7634 ("bpf: LRU List") for a full explanation of
+the corresponding operations:
+
+.. kernel-figure:: map_lru_hash_update.dot
+ :alt: Diagram outlining the LRU eviction steps taken during map update.
+
+ LRU hash eviction during map update for ``BPF_MAP_TYPE_LRU_HASH`` and
+ variants. See the dot file source for kernel function name code references.
+
+Map updates start from the oval in the top right "begin ``bpf_map_update()``"
+and progress through the graph towards the bottom where the result may be
+either a successful update or a failure with various error codes. The key in
+the top right provides indicators for which locks may be involved in specific
+operations. This is intended as a visual hint for reasoning about how map
+contention may impact update operations, though the map type and flags may
+impact the actual contention on those locks, based on the logic described in
+the table above. For instance, if the map is created with type
+``BPF_MAP_TYPE_LRU_PERCPU_HASH`` and flags ``BPF_F_NO_COMMON_LRU`` then all map
+properties would be per-cpu.

+BPF ABI Recommended Conventions and Guidelines v1.0
+===================================================
+
+This is version 1.0 of an informational document containing recommended
+conventions and guidelines for producing portable BPF program binaries.
+
+Registers and calling convention
+================================
+
+BPF has 10 general purpose registers and a read-only frame pointer register,
+all of which are 64-bits wide.
+
+The BPF calling convention is defined as:
+
+* R0: return value from function calls, and exit value for BPF programs
+* R1 - R5: arguments for function calls
+* R6 - R9: callee saved registers that function calls will preserve
+* R10: read-only frame pointer to access stack
+
+R0 - R5 are scratch registers and BPF programs needs to spill/fill them if
+necessary across calls.
+
+The BPF program needs to store the return value into register R0 before doing an
+``EXIT``.

+======================================
+BPF Instruction Set Architecture (ISA)
+======================================
+
+eBPF, also commonly
+referred to as BPF, is a technology with origins in the Linux kernel
+that can run untrusted programs in a privileged context such as an
+operating system kernel. This document specifies the BPF instruction
+set architecture (ISA).
+
+As a historical note, BPF originally stood for Berkeley Packet Filter,
+but now that it can do so much more than packet filtering, the acronym
+no longer makes sense. BPF is now considered a standalone term that
+does not stand for anything. The original BPF is sometimes referred to
+as cBPF (classic BPF) to distinguish it from the now widely deployed
+eBPF (extended BPF).
+
+Documentation conventions
+=========================
+
+The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
+"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
+"OPTIONAL" in this document are to be interpreted as described in
+BCP 14 `<https://www.rfc-editor.org/info/rfc2119>`_
+`<https://www.rfc-editor.org/info/rfc8174>`_
+when, and only when, they appear in all capitals, as shown here.
+
+For brevity and consistency, this document refers to families
+of types using a shorthand syntax and refers to several expository,
+mnemonic functions when describing the semantics of instructions.
+The range of valid values for those types and the semantics of those
+functions are defined in the following subsections.
+
+Types
+-----
+This document refers to integer types with the notation `SN` to specify
+a type's signedness (`S`) and bit width (`N`), respectively.
+

+ 8 8 bits
+ 16 16 bits
+ 32 32 bits
+ 64 64 bits
+ 128 128 bits
+ ===== =========
+
+For example, `u32` is a type whose valid values are all the 32-bit unsigned
+numbers and `s16` is a type whose valid values are all the 16-bit signed
+numbers.
+
+Functions
+---------
+
+The following byteswap functions are direction-agnostic. That is,
+the same function is used for conversion in either direction discussed
+below.
+
+* be16: Takes an unsigned 16-bit number and converts it between
+ host byte order and big-endian
+ (`IEN137 <https://www.rfc-editor.org/ien/ien137.txt>`_) byte order.
+* be32: Takes an unsigned 32-bit number and converts it between
+ host byte order and big-endian byte order.
+* be64: Takes an unsigned 64-bit number and converts it between
+ host byte order and big-endian byte order.
+* bswap16: Takes an unsigned 16-bit number in either big- or little-endian
+ format and returns the equivalent number with the same bit width but
+ opposite endianness.
+* bswap32: Takes an unsigned 32-bit number in either big- or little-endian
+ format and returns the equivalent number with the same bit width but
+ opposite endianness.
+* bswap64: Takes an unsigned 64-bit number in either big- or little-endian
+ format and returns the equivalent number with the same bit width but
+ opposite endianness.
+* le16: Takes an unsigned 16-bit number and converts it between
+ host byte order and little-endian byte order.
+* le32: Takes an unsigned 32-bit number and converts it between
+ host byte order and little-endian byte order.
+* le64: Takes an unsigned 64-bit number and converts it between
+ host byte order and little-endian byte order.

+
+Conformance groups
+------------------
+
+An implementation does not need to support all instructions specified in this
+document (e.g., deprecated instructions). Instead, a number of conformance
+groups are specified. An implementation MUST support the base32 conformance
+group and MAY support additional conformance groups, where supporting a
+conformance group means it MUST support all instructions in that conformance
+group.
+
+The use of named conformance groups enables interoperability between a runtime
+that executes instructions, and tools such as compilers that generate
+instructions for the runtime. Thus, capability discovery in terms of
+conformance groups might be done manually by users or automatically by tools.
+
+Each conformance group has a short ASCII label (e.g., "base32") that
+corresponds to a set of instructions that are mandatory. That is, each
+instruction has one or more conformance groups of which it is a member.
+
+This document defines the following conformance groups:
+
+* base32: includes all instructions defined in this
+ specification unless otherwise noted.
+* base64: includes base32, plus instructions explicitly noted
+ as being in the base64 conformance group.
+* atomic32: includes 32-bit atomic operation instructions (see `Atomic operations`_).
+* atomic64: includes atomic32, plus 64-bit atomic operation instructions.
+* divmul32: includes 32-bit division, multiplication, and modulo instructions.
+* divmul64: includes divmul32, plus 64-bit division, multiplication,
+ and modulo instructions.
+* packet: deprecated packet access instructions.
+
+Instruction encoding
+====================
+
+BPF has two instruction encodings:
+
+* the basic instruction encoding, which uses 64 bits to encode an instruction
+* the wide instruction encoding, which appends a second 64 bits
+ after the basic instruction for a total of 128 bits.
+
+Basic instruction encoding
+--------------------------
+
+A basic instruction is encoded as follows::
+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | opcode | regs | offset |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | imm |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+
+**opcode**
+ operation to perform, encoded as follows::
+
+ +-+-+-+-+-+-+-+-+
+ |specific |class|
+ +-+-+-+-+-+-+-+-+
+
+ **specific**
+ The format of these bits varies by instruction class
+
+ **class**
+ The instruction class (see `Instruction classes`_)
+
+**regs**
+ The source and destination register numbers, encoded as follows
+ on a little-endian host::
+
+ +-+-+-+-+-+-+-+-+
+ |src_reg|dst_reg|
+ +-+-+-+-+-+-+-+-+
+
+ and as follows on a big-endian host::
+
+ +-+-+-+-+-+-+-+-+
+ |dst_reg|src_reg|
+ +-+-+-+-+-+-+-+-+
+
+ **src_reg**
+ the source register number (0-10), except where otherwise specified
+ (`64-bit immediate instructions`_ reuse this field for other purposes)
+
+ **dst_reg**
+ destination register number (0-10), unless otherwise specified
+ (future instructions might reuse this field for other purposes)
+
+**offset**
+ signed integer offset used with pointer arithmetic, except where
+ otherwise specified (some arithmetic instructions reuse this field
+ for other purposes)
+
+**imm**
+ signed integer immediate value
+
+Note that the contents of multi-byte fields ('offset' and 'imm') are
+stored using big-endian byte ordering on big-endian hosts and
+little-endian byte ordering on little-endian hosts.
+
+For example::
+
+ opcode offset imm assembly
+ src_reg dst_reg
+ 07 0 1 00 00 44 33 22 11 r1 += 0x11223344 // little
+ dst_reg src_reg
+ 07 1 0 00 00 11 22 33 44 r1 += 0x11223344 // big
+
+Note that most instructions do not use all of the fields.
+Unused fields SHALL be cleared to zero.
+
+Wide instruction encoding
+--------------------------
+
+Some instructions are defined to use the wide instruction encoding,
+which uses two 32-bit immediate values. The 64 bits following
+the basic instruction format contain a pseudo instruction
+with 'opcode', 'dst_reg', 'src_reg', and 'offset' all set to zero.
+
+This is depicted in the following figure::
+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | opcode | regs | offset |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | imm |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | reserved |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | next_imm |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+
+**opcode**
+ operation to perform, encoded as explained above
+
+**regs**
+ The source and destination register numbers (unless otherwise
+ specified), encoded as explained above
+
+**offset**
+ signed integer offset used with pointer arithmetic, unless
+ otherwise specified
+
+**imm**
+ signed integer immediate value
+
+**reserved**
+ unused, set to zero
+
+**next_imm**
+ second signed integer immediate value
+
+Instruction classes
+-------------------
+
+The three least significant bits of the 'opcode' field store the instruction class:
+
+.. table:: Instruction class

+
+Arithmetic and jump instructions
+================================
+
+For arithmetic and jump instructions (``ALU``, ``ALU64``, ``JMP`` and
+``JMP32``), the 8-bit 'opcode' field is divided into three parts::
+
+ +-+-+-+-+-+-+-+-+
+ | code |s|class|
+ +-+-+-+-+-+-+-+-+
+
+**code**
+ the operation code, whose meaning varies by instruction class
+
+**s (source)**

+ the instruction class (see `Instruction classes`_)
+
+Arithmetic instructions
+-----------------------
+
+``ALU`` uses 32-bit wide operands while ``ALU64`` uses 64-bit wide operands for
+otherwise identical operations. ``ALU64`` instructions belong to the
+base64 conformance group unless noted otherwise.
+The 'code' field encodes the operation as below, where 'src' refers to the
+the source operand and 'dst' refers to the value of the destination
+register.

+
+Underflow and overflow are allowed during arithmetic operations, meaning
+the 64-bit or 32-bit value will wrap. If BPF program execution would
+result in division by zero, the destination register is instead set to zero.
+Otherwise, for ``ALU64``, if execution would result in ``LLONG_MIN``
+divided by -1, the destination register is instead set to ``LLONG_MIN``. For
+``ALU``, if execution would result in ``INT_MIN`` divided by -1, the
+destination register is instead set to ``INT_MIN``.
+
+If execution would result in modulo by zero, for ``ALU64`` the value of
+the destination register is unchanged whereas for ``ALU`` the upper
+32 bits of the destination register are zeroed. Otherwise, for ``ALU64``,
+if execution would resuslt in ``LLONG_MIN`` modulo -1, the destination
+register is instead set to 0. For ``ALU``, if execution would result in
+``INT_MIN`` modulo -1, the destination register is instead set to 0.
+
+``{ADD, X, ALU}``, where 'code' = ``ADD``, 'source' = ``X``, and 'class' = ``ALU``, means::
+
+ dst = (u32) ((u32) dst + (u32) src)
+
+where '(u32)' indicates that the upper 32 bits are zeroed.
+
+``{ADD, X, ALU64}`` means::
+
+ dst = dst + src
+
+``{XOR, K, ALU}`` means::
+
+ dst = (u32) dst ^ (u32) imm
+
+``{XOR, K, ALU64}`` means::
+
+ dst = dst ^ imm
+
+Note that most arithmetic instructions have 'offset' set to 0. Only three instructions
+(``SDIV``, ``SMOD``, ``MOVSX``) have a non-zero 'offset'.
+
+Division, multiplication, and modulo operations for ``ALU`` are part
+of the "divmul32" conformance group, and division, multiplication, and
+modulo operations for ``ALU64`` are part of the "divmul64" conformance
+group.
+The division and modulo operations support both unsigned and signed flavors.
+
+For unsigned operations (``DIV`` and ``MOD``), for ``ALU``,
+'imm' is interpreted as a 32-bit unsigned value. For ``ALU64``,
+'imm' is first :term:`sign extended<Sign Extend>` from 32 to 64 bits, and then
+interpreted as a 64-bit unsigned value.
+
+For signed operations (``SDIV`` and ``SMOD``), for ``ALU``,
+'imm' is interpreted as a 32-bit signed value. For ``ALU64``, 'imm'
+is first :term:`sign extended<Sign Extend>` from 32 to 64 bits, and then
+interpreted as a 64-bit signed value.
+
+Note that there are varying definitions of the signed modulo operation
+when the dividend or divisor are negative, where implementations often
+vary by language such that Python, Ruby, etc. differ from C, Go, Java,
+etc. This specification requires that signed modulo MUST use truncated division
+(where -13 % 3 == -1) as implemented in C, Go, etc.::
+
+ a % n = a - n * trunc(a / n)
+
+The ``MOVSX`` instruction does a move operation with sign extension.
+``{MOVSX, X, ALU}`` :term:`sign extends<Sign Extend>` 8-bit and 16-bit operands into
+32-bit operands, and zeroes the remaining upper 32 bits.
+``{MOVSX, X, ALU64}`` :term:`sign extends<Sign Extend>` 8-bit, 16-bit, and 32-bit
+operands into 64-bit operands. Unlike other arithmetic instructions,
+``MOVSX`` is only defined for register source operands (``X``).
+
+``{MOV, K, ALU64}`` means::
+
+ dst = (s64)imm
+
+``{MOV, X, ALU}`` means::
+
+ dst = (u32)src
+
+``{MOVSX, X, ALU}`` with 'offset' 8 means::
+
+ dst = (u32)(s32)(s8)src
+
+
+The ``NEG`` instruction is only defined when the source bit is clear
+(``K``).
+
+Shift operations use a mask of 0x3F (63) for 64-bit operations and 0x1F (31)
+for 32-bit operations.
+
+Byte swap instructions
+----------------------
+
+The byte swap instructions use instruction classes of ``ALU`` and ``ALU64``
+and a 4-bit 'code' field of ``END``.
+
+The byte swap instructions operate on the destination register
+only and do not use a separate source register or immediate value.
+
+For ``ALU``, the 1-bit source operand field in the opcode is used to
+select what byte order the operation converts from or to. For
+``ALU64``, the 1-bit source operand field in the opcode is reserved
+and MUST be set to 0.
+
+.. table:: Byte swap instructions
+
+ ===== ======== ===== =================================================

+ ===== ======== ===== =================================================
+ ALU LE 0 convert between host byte order and little endian
+ ALU BE 1 convert between host byte order and big endian
+ ALU64 Reserved 0 do byte swap unconditionally
+ ===== ======== ===== =================================================
+
+The 'imm' field encodes the width of the swap operations. The following widths
+are supported: 16, 32 and 64. Width 64 operations belong to the base64
+conformance group and other swap operations belong to the base32
+conformance group.
+
+Examples:
+
+``{END, LE, ALU}`` with 'imm' = 16/32/64 means::
+
+ dst = le16(dst)
+ dst = le32(dst)
+ dst = le64(dst)
+
+``{END, BE, ALU}`` with 'imm' = 16/32/64 means::
+
+ dst = be16(dst)
+ dst = be32(dst)
+ dst = be64(dst)
+
+``{END, TO, ALU64}`` with 'imm' = 16/32/64 means::
+
+ dst = bswap16(dst)
+ dst = bswap32(dst)
+ dst = bswap64(dst)
+
+Jump instructions
+-----------------
+
+``JMP32`` uses 32-bit wide operands and indicates the base32
+conformance group, while ``JMP`` uses 64-bit wide operands for
+otherwise identical operations, and indicates the base64 conformance
+group unless otherwise specified.
+The 'code' field encodes the operation as below:
+
+.. table:: Jump instructions

+
+where 'PC' denotes the program counter, and the offset to increment by
+is in units of 64-bit instructions relative to the instruction following
+the jump instruction. Thus 'PC += 1' skips execution of the next
+instruction if it's a basic instruction or results in undefined behavior
+if the next instruction is a 128-bit wide instruction.
+
+Example:
+
+``{JSGE, X, JMP32}`` means::
+
+ if (s32)dst s>= (s32)src goto +offset
+
+where 's>=' indicates a signed '>=' comparison.
+
+``{JLE, K, JMP}`` means::
+
+ if dst <= (u64)(s64)imm goto +offset
+
+``{JA, K, JMP32}`` means::
+
+ gotol +imm
+
+where 'imm' means the branch offset comes from the 'imm' field.
+
+Note that there are two flavors of ``JA`` instructions. The
+``JMP`` class permits a 16-bit jump offset specified by the 'offset'
+field, whereas the ``JMP32`` class permits a 32-bit jump offset
+specified by the 'imm' field. A > 16-bit conditional jump may be
+converted to a < 16-bit conditional jump plus a 32-bit unconditional
+jump.
+
+All ``CALL`` and ``JA`` instructions belong to the
+base32 conformance group.
+
+Helper functions
+~~~~~~~~~~~~~~~~
+
+Helper functions are a concept whereby BPF programs can call into a
+set of function calls exposed by the underlying platform.
+
+Historically, each helper function was identified by a static ID
+encoded in the 'imm' field. Further documentation of helper functions
+is outside the scope of this document and standardization is left for
+future work, but use is widely deployed and more information can be
+found in platform-specific documentation (e.g., Linux kernel documentation).
+
+Platforms that support the BPF Type Format (BTF) support identifying
+a helper function by a BTF ID encoded in the 'imm' field, where the BTF ID
+identifies the helper name and type. Further documentation of BTF
+is outside the scope of this document and standardization is left for
+future work, but use is widely deployed and more information can be
+found in platform-specific documentation (e.g., Linux kernel documentation).
+
+Program-local functions
+~~~~~~~~~~~~~~~~~~~~~~~
+Program-local functions are functions exposed by the same BPF program as the
+caller, and are referenced by offset from the instruction following the call
+instruction, similar to ``JA``. The offset is encoded in the 'imm' field of
+the call instruction. An ``EXIT`` within the program-local function will
+return to the caller.
+
+Load and store instructions
+===========================
+
+For load and store instructions (``LD``, ``LDX``, ``ST``, and ``STX``), the
+8-bit 'opcode' field is divided as follows::
+
+ +-+-+-+-+-+-+-+-+
+ |mode |sz |class|
+ +-+-+-+-+-+-+-+-+

+
+**class**
+ The instruction class (see `Instruction classes`_)
+
+Regular load and store operations
+---------------------------------
+
+The ``MEM`` mode modifier is used to encode regular load and store
+instructions that transfer data between a register and memory.
+
+``{MEM, <size>, STX}`` means::
+
+ *(size *) (dst + offset) = src
+
+``{MEM, <size>, ST}`` means::
+
+ *(size *) (dst + offset) = imm
+
+``{MEM, <size>, LDX}`` means::
+
+ dst = *(unsigned size *) (src + offset)
+
+Where '<size>' is one of: ``B``, ``H``, ``W``, or ``DW``, and
+'unsigned size' is one of: u8, u16, u32, or u64.
+
+Sign-extension load operations
+------------------------------
+
+The ``MEMSX`` mode modifier is used to encode :term:`sign-extension<Sign Extend>` load
+instructions that transfer data between a register and memory.
+
+``{MEMSX, <size>, LDX}`` means::
+
+ dst = *(signed size *) (src + offset)
+
+Where '<size>' is one of: ``B``, ``H``, or ``W``, and
+'signed size' is one of: s8, s16, or s32.
+
+Atomic operations
+-----------------
+
+Atomic operations are operations that operate on memory and can not be
+interrupted or corrupted by other access to the same memory region
+by other BPF programs or means outside of this specification.
+
+All atomic operations supported by BPF are encoded as store operations
+that use the ``ATOMIC`` mode modifier as follows:
+
+* ``{ATOMIC, W, STX}`` for 32-bit operations, which are
+ part of the "atomic32" conformance group.
+* ``{ATOMIC, DW, STX}`` for 64-bit operations, which are
+ part of the "atomic64" conformance group.
+* 8-bit and 16-bit wide atomic operations are not supported.
+
+The 'imm' field is used to encode the actual atomic operation.
+Simple atomic operation use a subset of the values defined to encode
+arithmetic operations in the 'imm' field to encode the atomic operation:
+
+.. table:: Simple atomic operations
+
+ ======== ===== ===========
+ imm value description
+ ======== ===== ===========
+ ADD 0x00 atomic add
+ OR 0x40 atomic or
+ AND 0x50 atomic and
+ XOR 0xa0 atomic xor
+ ======== ===== ===========
+
+
+``{ATOMIC, W, STX}`` with 'imm' = ADD means::
+
+ *(u32 *)(dst + offset) += src
+
+``{ATOMIC, DW, STX}`` with 'imm' = ADD means::
+
+ *(u64 *)(dst + offset) += src
+
+In addition to the simple atomic operations, there also is a modifier and
+two complex atomic operations:
+
+.. table:: Complex atomic operations
+
+ =========== ================ ===========================
+ imm value description
+ =========== ================ ===========================
+ FETCH 0x01 modifier: return old value
+ XCHG 0xe0 | FETCH atomic exchange
+ CMPXCHG 0xf0 | FETCH atomic compare and exchange
+ =========== ================ ===========================
+
+The ``FETCH`` modifier is optional for simple atomic operations, and
+always set for the complex atomic operations. If the ``FETCH`` flag
+is set, then the operation also overwrites ``src`` with the value that
+was in memory before it was modified.
+
+The ``XCHG`` operation atomically exchanges ``src`` with the value
+addressed by ``dst + offset``.
+
+The ``CMPXCHG`` operation atomically compares the value addressed by
+``dst + offset`` with ``R0``. If they match, the value addressed by
+``dst + offset`` is replaced with ``src``. In either case, the
+value that was at ``dst + offset`` before the operation is zero-extended
+and loaded back to ``R0``.
+
+64-bit immediate instructions
+-----------------------------
+
+Instructions with the ``IMM`` 'mode' modifier use the wide instruction
+encoding defined in `Instruction encoding`_, and use the 'src_reg' field of the
+basic instruction to hold an opcode subtype.
+
+The following table defines a set of ``{IMM, DW, LD}`` instructions
+with opcode subtypes in the 'src_reg' field, using new terms such as "map"
+defined further below:
+
+.. table:: 64-bit immediate instructions
+
+ ======= ========================================= =========== ==============
+ src_reg pseudocode imm type dst type
+ ======= ========================================= =========== ==============
+ 0x0 dst = (next_imm << 32) | imm integer integer
+ 0x1 dst = map_by_fd(imm) map fd map
+ 0x2 dst = map_val(map_by_fd(imm)) + next_imm map fd data address
+ 0x3 dst = var_addr(imm) variable id data address
+ 0x4 dst = code_addr(imm) integer code address
+ 0x5 dst = map_by_idx(imm) map index map
+ 0x6 dst = map_val(map_by_idx(imm)) + next_imm map index data address
+ ======= ========================================= =========== ==============
+
+where
+
+* map_by_fd(imm) means to convert a 32-bit file descriptor into an address of a map (see `Maps`_)
+* map_by_idx(imm) means to convert a 32-bit index into an address of a map
+* map_val(map) gets the address of the first value in a given map
+* var_addr(imm) gets the address of a platform variable (see `Platform Variables`_) with a given id
+* code_addr(imm) gets the address of the instruction at a specified relative offset in number of (64-bit) instructions
+* the 'imm type' can be used by disassemblers for display
+* the 'dst type' can be used for verification and JIT compilation purposes
+
+Maps
+~~~~
+
+Maps are shared memory regions accessible by BPF programs on some platforms.
+A map can have various semantics as defined in a separate document, and may or
+may not have a single contiguous memory region, but the 'map_val(map)' is
+currently only defined for maps that do have a single contiguous memory region.
+
+Each map can have a file descriptor (fd) if supported by the platform, where
+'map_by_fd(imm)' means to get the map with the specified file descriptor. Each
+BPF program can also be defined to use a set of maps associated with the
+program at load time, and 'map_by_idx(imm)' means to get the map with the given
+index in the set associated with the BPF program containing the instruction.
+
+Platform Variables
+~~~~~~~~~~~~~~~~~~
+
+Platform variables are memory regions, identified by integer ids, exposed by
+the runtime and accessible by BPF programs on some platforms. The
+'var_addr(imm)' operation means to get the address of the memory region
+identified by the given id.
+
+Legacy BPF Packet access instructions
+-------------------------------------
+
+BPF previously introduced special instructions for access to packet data that were
+carried over from classic BPF. These instructions used an instruction
+class of ``LD``, a size modifier of ``W``, ``H``, or ``B``, and a
+mode modifier of ``ABS`` or ``IND``. The 'dst_reg' and 'offset' fields were
+set to zero, and 'src_reg' was set to zero for ``ABS``. However, these
+instructions are deprecated and SHOULD no longer be used. All legacy packet
+access instructions belong to the "packet" conformance group.

- enum bpf_reg_liveness {
- REG_LIVE_NONE = 0,
- REG_LIVE_READ32 = 0x1,
- REG_LIVE_READ64 = 0x2,

- }
-
-* ``REG_LIVE_NONE`` is an initial value assigned to ``->live`` fields upon new
- verifier state creation;
-
-* ``REG_LIVE_WRITTEN`` means that the value of the register (or stack slot) is
- defined by some instruction verified between this verifier state's parent and
- verifier state itself;
-
-* ``REG_LIVE_READ{32,64}`` means that the value of the register (or stack slot)
- is read by a some child state of this verifier state;
-
-* ``REG_LIVE_DONE`` is a marker used by ``clean_verifier_state()`` to avoid
- processing same verifier state multiple times and for some sanity checks;
-
-* ``->live`` field values are formed by combining ``enum bpf_reg_liveness``
- values using bitwise or.
-
-Register parentage chains
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In order to propagate information between parent and child states, a *register
-parentage chain* is established. Each register or stack slot is linked to a
-corresponding register or stack slot in its parent state via a ``->parent``
-pointer. This link is established upon state creation in ``is_state_visited()``
-and might be modified by ``set_callee_state()`` called from
-``__check_func_call()``.
-
-The rules for correspondence between registers / stack slots are as follows:
-
-* For the current stack frame, registers and stack slots of the new state are
- linked to the registers and stack slots of the parent state with the same
- indices.
-
-* For the outer stack frames, only caller saved registers (r6-r9) and stack
- slots are linked to the registers and stack slots of the parent state with the
- same indices.
-
-* When function call is processed a new ``struct bpf_func_state`` instance is
- allocated, it encapsulates a new set of registers and stack slots. For this
- new frame, parent links for r6-r9 and stack slots are set to nil, parent links
- for r1-r5 are set to match caller r1-r5 parent links.
-
-This could be illustrated by the following diagram (arrows stand for
-``->parent`` pointers)::
-
- ... ; Frame #0, some instructions
- --- checkpoint #0 ---
- 1 : r6 = 42 ; Frame #0
- --- checkpoint #1 ---

- r6 read mark is propagated via these links
- all the way up to checkpoint #1.
- The checkpoint #1 contains a write mark for r6
- because of instruction (1), thus read propagation
- does not reach checkpoint #0 (see section below).
-
-Liveness marks tracking
-~~~~~~~~~~~~~~~~~~~~~~~
-
-For each processed instruction, the verifier tracks read and written registers
-and stack slots. The main idea of the algorithm is that read marks propagate
-back along the state parentage chain until they hit a write mark, which 'screens
-off' earlier states from the read. The information about reads is propagated by
-function ``mark_reg_read()`` which could be summarized as follows::
-
- mark_reg_read(struct bpf_reg_state *state, ...):
- parent = state->parent
- while parent:
- if state->live & REG_LIVE_WRITTEN:
- break
- if parent->live & REG_LIVE_READ64:
- break
- parent->live |= REG_LIVE_READ64
- state = parent
- parent = state->parent
-
-Notes:
-
-* The read marks are applied to the **parent** state while write marks are
- applied to the **current** state. The write mark on a register or stack slot
- means that it is updated by some instruction in the straight-line code leading
- from the parent state to the current state.
-
-* Details about REG_LIVE_READ32 are omitted.
-
-* Function ``propagate_liveness()`` (see section :ref:`read_marks_for_cache_hits`)
- might override the first parent link. Please refer to the comments in the
- ``propagate_liveness()`` and ``mark_reg_read()`` source code for further
- details.
-
-Because stack writes could have different sizes ``REG_LIVE_WRITTEN`` marks are
-applied conservatively: stack slots are marked as written only if write size
-corresponds to the size of the register, e.g. see function ``save_register_state()``.
-
-Consider the following example::
-
- 0: (*u64)(r10 - 8) = 0 ; define 8 bytes of fp-8
- --- checkpoint #0 ---
- 1: (*u32)(r10 - 8) = 1 ; redefine lower 4 bytes
- 2: r1 = (*u32)(r10 - 8) ; read lower 4 bytes defined at (1)
- 3: r2 = (*u32)(r10 - 4) ; read upper 4 bytes defined at (0)
-
-As stated above, the write at (1) does not count as ``REG_LIVE_WRITTEN``. Should
-it be otherwise, the algorithm above wouldn't be able to propagate the read mark
-from (3) to checkpoint #0.
-
-Once the ``BPF_EXIT`` instruction is reached ``update_branch_counts()`` is
-called to update the ``->branches`` counter for each verifier state in a chain
-of parent verifier states. When the ``->branches`` counter reaches zero the
-verifier state becomes a valid entry in a set of cached verifier states.
-
-Each entry of the verifier states cache is post-processed by a function
-``clean_live_states()``. This function marks all registers and stack slots
-without ``REG_LIVE_READ{32,64}`` marks as ``NOT_INIT`` or ``STACK_INVALID``.
-Registers/stack slots marked in this way are ignored in function ``stacksafe()``
-called from ``states_equal()`` when a state cache entry is considered for
-equivalence with a current state.
-
-Now it is possible to explain how the example from the beginning of the section
-works::
-
- 0: call bpf_get_prandom_u32()
- 1: r1 = 0
- 2: if r0 == 0 goto +1
- 3: r0 = 1
- --- checkpoint[0] ---
- 4: r0 = r1
- 5: exit
-
-* At instruction #2 branching point is reached and state ``{ r0 == 0, r1 == 0, pc == 4 }``
- is pushed to states processing queue (pc stands for program counter).
-
-* At instruction #4:
-
- * ``checkpoint[0]`` states cache entry is created: ``{ r0 == 1, r1 == 0, pc == 4 }``;
- * ``checkpoint[0].r0`` is marked as written;
- * ``checkpoint[0].r1`` is marked as read;
-
-* At instruction #5 exit is reached and ``checkpoint[0]`` can now be processed
- by ``clean_live_states()``. After this processing ``checkpoint[0].r0`` has a
- read mark and all other registers and stack slots are marked as ``NOT_INIT``
- or ``STACK_INVALID``
-
-* The state ``{ r0 == 0, r1 == 0, pc == 4 }`` is popped from the states queue
- and is compared against a cached state ``{ r1 == 0, pc == 4 }``, the states
- are considered equivalent.
-
-.. _read_marks_for_cache_hits:
-
-Read marks propagation for cache hits
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Another point is the handling of read marks when a previously verified state is
-found in the states cache. Upon cache hit verifier must behave in the same way
-as if the current state was verified to the program exit. This means that all
-read marks, present on registers and stack slots of the cached state, must be
-propagated over the parentage chain of the current state. Example below shows
-why this is important. Function ``propagate_liveness()`` handles this case.
-
-Consider the following state parentage chain (S is a starting state, A-E are
-derived states, -> arrows show which state is derived from which)::
-
- r1 read
- <------------- A[r1] == 0
- C[r1] == 0
- S ---> A ---> B ---> exit E[r1] == 1
- |
- ` ---> C ---> D
- |
- ` ---> E ^
- |___ suppose all these
- ^ states are at insn #Y
- |
- suppose all these
- states are at insn #X
-
-* Chain of states ``S -> A -> B -> exit`` is verified first.
-
-* While ``B -> exit`` is verified, register ``r1`` is read and this read mark is
- propagated up to state ``A``.
-
-* When chain of states ``C -> D`` is verified the state ``D`` turns out to be
- equivalent to state ``B``.
-
-* The read mark for ``r1`` has to be propagated to state ``C``, otherwise state
- ``C`` might get mistakenly marked as equivalent to state ``E`` even though
- values for register ``r1`` differ between ``C`` and ``E``.

-Packet writing
-==============
-
-Getting started quick
----------------------
-
-- Select packet support in the block device section and UDF support in
- the file system section.
-
-- Compile and install kernel and modules, reboot.
-
-- You need the udftools package (pktsetup, mkudffs, cdrwtool).
- Download from https://github.com/pali/udftools
-
-- Grab a new CD-RW disc and format it (assuming CD-RW is hdc, substitute
- as appropriate)::
-
- # cdrwtool -d /dev/hdc -q
-
-- Setup your writer::
-
- # pktsetup dev_name /dev/hdc
-
-- Now you can mount /dev/pktcdvd/dev_name and copy files to it. Enjoy::
-
- # mount /dev/pktcdvd/dev_name /cdrom -t udf -o rw,noatime
-
-
-Packet writing for DVD-RW media
--------------------------------
-
-DVD-RW discs can be written to much like CD-RW discs if they are in
-the so called "restricted overwrite" mode. To put a disc in restricted
-overwrite mode, run::
-
- # dvd+rw-format /dev/hdc
-
-You can then use the disc the same way you would use a CD-RW disc::
-
- # pktsetup dev_name /dev/hdc
- # mount /dev/pktcdvd/dev_name /cdrom -t udf -o rw,noatime
-
-
-Packet writing for DVD+RW media
--------------------------------
-
-According to the DVD+RW specification, a drive supporting DVD+RW discs
-shall implement "true random writes with 2KB granularity", which means
-that it should be possible to put any filesystem with a block size >=
-2KB on such a disc. For example, it should be possible to do::
-
- # dvd+rw-format /dev/hdc (only needed if the disc has never
- been formatted)
- # mkudffs /dev/hdc
- # mount /dev/hdc /cdrom -t udf -o rw,noatime
-
-However, some drives don't follow the specification and expect the
-host to perform aligned writes at 32KB boundaries. Other drives do
-follow the specification, but suffer bad performance problems if the
-writes are not 32KB aligned.
-
-Both problems can be solved by using the pktcdvd driver, which always
-generates aligned writes::
-
- # dvd+rw-format /dev/hdc
- # pktsetup dev_name /dev/hdc
- # mkudffs /dev/pktcdvd/dev_name
- # mount /dev/pktcdvd/dev_name /cdrom -t udf -o rw,noatime
-
-
-Packet writing for DVD-RAM media
---------------------------------
-
-DVD-RAM discs are random writable, so using the pktcdvd driver is not
-necessary. However, using the pktcdvd driver can improve performance
-in the same way it does for DVD+RW media.
-
-
-Notes
------
-
-- CD-RW media can usually not be overwritten more than about 1000
- times, so to avoid unnecessary wear on the media, you should always
- use the noatime mount option.
-
-- Defect management (ie automatic remapping of bad sectors) has not
- been implemented yet, so you are likely to get at least some
- filesystem corruption if the disc wears out.
-
-- Since the pktcdvd driver makes the disc appear as a regular block
- device with a 2KB block size, you can put any filesystem you like on
- the disc. For example, run::
-
- # /sbin/mke2fs /dev/pktcdvd/dev_name
-
- to create an ext2 filesystem on the disc.
-
-
-Using the pktcdvd sysfs interface
----------------------------------
-
-Since Linux 2.6.20, the pktcdvd module has a sysfs interface
-and can be controlled by it. For example the "pktcdvd" tool uses
-this interface. (see http://tom.ist-im-web.de/linux/software/pktcdvd )
-
-"pktcdvd" works similar to "pktsetup", e.g.::
-
- # pktcdvd -a dev_name /dev/hdc
- # mkudffs /dev/pktcdvd/dev_name
- # mount -t udf -o rw,noatime /dev/pktcdvd/dev_name /dvdram
- # cp files /dvdram
- # umount /dvdram
- # pktcdvd -r dev_name
-
-
-For a description of the sysfs interface look into the file:
-
- Documentation/ABI/testing/sysfs-class-pktcdvd
-
-
-Using the pktcdvd debugfs interface
------------------------------------
-
-To read pktcdvd device infos in human readable form, do::
-
- # cat /sys/kernel/debug/pktcdvd/pktcdvd[0-7]/info
-
-For a description of the debugfs interface look into the file:
-
- Documentation/ABI/testing/debugfs-pktcdvd

--------------------------------
+Streaming DMA allows to map an existing buffer for DMA transfers and then

+return value must be checked.
+
+.. note::
+
+ In particular, mapping may fail for memory not addressable by the

+Floating-point API
+==================
+
+Kernel code is normally prohibited from using floating-point (FP) registers or
+instructions, including the C float and double data types. This rule reduces
+system call overhead, because the kernel does not need to save and restore the
+userspace floating-point register state.
+
+However, occasionally drivers or library functions may need to include FP code.
+This is supported by isolating the functions containing FP code to a separate
+translation unit (a separate source file), and saving/restoring the FP register
+state around calls to those functions. This creates "critical sections" of
+floating-point usage.
+
+The reason for this isolation is to prevent the compiler from generating code
+touching the FP registers outside these critical sections. Compilers sometimes
+use FP registers to optimize inlined ``memcpy`` or variable assignment, as
+floating-point registers may be wider than general-purpose registers.
+
+Usability of floating-point code within the kernel is architecture-specific.
+Additionally, because a single kernel may be configured to support platforms
+both with and without a floating-point unit, FPU availability must be checked
+both at build time and at run time.
+
+Several architectures implement the generic kernel floating-point API from
+``linux/fpu.h``, as described below. Some other architectures implement their
+own unique APIs, which are documented separately.
+
+Build-time API
+--------------
+
+Floating-point code may be built if the option ``ARCH_HAS_KERNEL_FPU_SUPPORT``
+is enabled. For C code, such code must be placed in a separate file, and that
+file must have its compilation flags adjusted using the following pattern::
+
+ CFLAGS_foo.o += $(CC_FLAGS_FPU)
+ CFLAGS_REMOVE_foo.o += $(CC_FLAGS_NO_FPU)
+
+Architectures are expected to define one or both of these variables in their
+top-level Makefile as needed. For example::
+
+ CC_FLAGS_FPU := -mhard-float
+
+or::
+
+ CC_FLAGS_NO_FPU := -msoft-float
+
+Normal kernel code is assumed to use the equivalent of ``CC_FLAGS_NO_FPU``.
+
+Runtime API
+-----------
+
+The runtime API is provided in ``linux/fpu.h``. This header cannot be included
+from files implementing FP code (those with their compilation flags adjusted as
+above). Instead, it must be included when defining the FP critical sections.
+
+.. c:function:: bool kernel_fpu_available( void )
+
+ This function reports if floating-point code can be used on this CPU or
+ platform. The value returned by this function is not expected to change
+ at runtime, so it only needs to be called once, not before every
+ critical section.
+
+.. c:function:: void kernel_fpu_begin( void )
+ void kernel_fpu_end( void )
+
+ These functions create a floating-point critical section. It is only
+ valid to call ``kernel_fpu_begin()`` after a previous call to
+ ``kernel_fpu_available()`` returned ``true``. These functions are only
+ guaranteed to be callable from (preemptible or non-preemptible) process
+ context.
+
+ Preemption may be disabled inside critical sections, so their size
+ should be minimized. They are *not* required to be reentrant. If the
+ caller expects to nest critical sections, it must implement its own
+ reference counting.

+
+
+Overview
+========
+
+The folio_queue struct forms a single segment in a segmented list of folios
+that can be used to form an I/O buffer. As such, the list can be iterated over
+using the ITER_FOLIOQ iov_iter type.
+
+The publicly accessible members of the structure are::
+
+ struct folio_queue {
+ struct folio_queue *next;
+ struct folio_queue *prev;
+ ...
+ };
+
+A pair of pointers are provided, ``next`` and ``prev``, that point to the
+segments on either side of the segment being accessed. Whilst this is a
+doubly-linked list, it is intentionally not a circular list; the outward
+sibling pointers in terminal segments should be NULL.
+
+Each segment in the list also stores:
+
+ * an ordered sequence of folio pointers,
+ * the size of each folio and
+ * three 1-bit marks per folio,
+
+but these should not be accessed directly as the underlying data structure may
+change, but rather the access functions outlined below should be used.
+
+The facility can be made accessible by::
+
+ #include <linux/folio_queue.h>
+
+and to use the iterator::
+
+ #include <linux/uio.h>
+
+
+Initialisation
+==============
+
+A segment should be initialised by calling::
+
+ void folioq_init(struct folio_queue *folioq);
+
+with a pointer to the segment to be initialised. Note that this will not
+necessarily initialise all the folio pointers, so care must be taken to check
+the number of folios added.
+
+
+Adding and removing folios
+==========================
+
+Folios can be set in the next unused slot in a segment struct by calling one
+of::
+
+ unsigned int folioq_append(struct folio_queue *folioq,
+ struct folio *folio);
+
+ unsigned int folioq_append_mark(struct folio_queue *folioq,
+ struct folio *folio);
+
+Both functions update the stored folio count, store the folio and note its
+size. The second function also sets the first mark for the folio added. Both
+functions return the number of the slot used. [!] Note that no attempt is made
+to check that the capacity wasn't overrun and the list will not be extended
+automatically.
+
+A folio can be excised by calling::
+
+ void folioq_clear(struct folio_queue *folioq, unsigned int slot);
+
+This clears the slot in the array and also clears all the marks for that folio,
+but doesn't change the folio count - so future accesses of that slot must check
+if the slot is occupied.
+
+
+Querying information about a folio
+==================================
+
+Information about the folio in a particular slot may be queried by the
+following function::
+
+ struct folio *folioq_folio(const struct folio_queue *folioq,
+ unsigned int slot);
+
+If a folio has not yet been set in that slot, this may yield an undefined
+pointer. The size of the folio in a slot may be queried with either of::
+
+ unsigned int folioq_folio_order(const struct folio_queue *folioq,
+ unsigned int slot);
+
+ size_t folioq_folio_size(const struct folio_queue *folioq,
+ unsigned int slot);
+
+The first function returns the size as an order and the second as a number of
+bytes.
+
+
+Querying information about a folio_queue
+========================================
+
+Information may be retrieved about a particular segment with the following
+functions::
+
+ unsigned int folioq_nr_slots(const struct folio_queue *folioq);
+
+ unsigned int folioq_count(struct folio_queue *folioq);
+
+ bool folioq_full(struct folio_queue *folioq);
+
+The first function returns the maximum capacity of a segment. It must not be
+assumed that this won't vary between segments. The second returns the number
+of folios added to a segments and the third is a shorthand to indicate if the
+segment has been filled to capacity.
+
+Not that the count and fullness are not affected by clearing folios from the
+segment. These are more about indicating how many slots in the array have been
+initialised, and it assumed that slots won't get reused, but rather the segment
+will get discarded as the queue is consumed.
+
+
+Folio marks
+===========
+
+Folios within a queue can also have marks assigned to them. These marks can be
+used to note information such as if a folio needs folio_put() calling upon it.
+There are three marks available to be set for each folio.
+
+The marks can be set by::
+
+ void folioq_mark(struct folio_queue *folioq, unsigned int slot);
+ void folioq_mark2(struct folio_queue *folioq, unsigned int slot);
+
+Cleared by::
+
+ void folioq_unmark(struct folio_queue *folioq, unsigned int slot);
+ void folioq_unmark2(struct folio_queue *folioq, unsigned int slot);
+
+And the marks can be queried by::
+
+ bool folioq_is_marked(const struct folio_queue *folioq, unsigned int slot);
+ bool folioq_is_marked2(const struct folio_queue *folioq, unsigned int slot);
+
+The marks can be used for any purpose and are not interpreted by this API.
+
+
+Folio queue iteration
+=====================
+
+A list of segments may be iterated over using the I/O iterator facility using
+an ``iov_iter`` iterator of ``ITER_FOLIOQ`` type. The iterator may be
+initialised with::
+
+ void iov_iter_folio_queue(struct iov_iter *i, unsigned int direction,
+ const struct folio_queue *folioq,
+ unsigned int first_slot, unsigned int offset,
+ size_t count);
+
+This may be told to start at a particular segment, slot and offset within a
+queue. The iov iterator functions will follow the next pointers when advancing
+and prev pointers when reverting when needed.

+Lockless simultaneous production/consumption issues
+===================================================
+
+If properly managed, the list can be extended by the producer at the head end
+and shortened by the consumer at the tail end simultaneously without the need
+to take locks. The ITER_FOLIOQ iterator inserts appropriate barriers to aid
+with this.
+
+Care must be taken when simultaneously producing and consuming a list. If the
+last segment is reached and the folios it refers to are entirely consumed by
+the IOV iterators, an iov_iter struct will be left pointing to the last segment
+with a slot number equal to the capacity of that segment. The iterator will
+try to continue on from this if there's another segment available when it is
+used again, but care must be taken lest the segment got removed and freed by
+the consumer before the iterator was advanced.
+
+It is recommended that the queue always contain at least one segment, even if
+that segment has never been filled or is entirely spent. This prevents the
+head and tail pointers from collapsing.

-The function will return a pointer to the irq_domain on success. The caller

+struct irq_domain could be defined as an irq domain controller. That
+is, it handles the mapping between hardware and virtual interrupt
+numbers for a given interrupt domain. The domain structure is
+generally created by the PIC code for a given PIC instance (though a
+domain can cover more than one PIC if they have a flat number model).
+It is the domain callbacks that are responsible for setting the
+irq_chip on a given irq_desc after it has been mapped.
+
+The host code and data structures use a fwnode_handle pointer to
+identify the domain. In some cases, and in order to preserve source
+code compatibility, this fwnode pointer is "upgraded" to a DT
+device_node. For those firmware infrastructures that do not provide a

In most cases, the irq_domain will begin empty without any mappings

+=======================
+Kexec Handover Concepts
+=======================
+
+Kexec HandOver (KHO) is a mechanism that allows Linux to preserve memory
+regions, which could contain serialized system states, across kexec.
+
+It introduces multiple concepts:
+
+KHO FDT
+=======
+
+Every KHO kexec carries a KHO specific flattened device tree (FDT) blob
+that describes preserved memory regions. These regions contain either
+serialized subsystem states, or in-memory data that shall not be touched
+across kexec. After KHO, subsystems can retrieve and restore preserved
+memory regions from KHO FDT.
+
+KHO only uses the FDT container format and libfdt library, but does not
+adhere to the same property semantics that normal device trees do: Properties
+are passed in native endianness and standardized properties like ``regs`` and
+``ranges`` do not exist, hence there are no ``#...-cells`` properties.
+
+KHO is still under development. The FDT schema is unstable and would change
+in the future.
+
+Scratch Regions
+===============
+
+To boot into kexec, we need to have a physically contiguous memory range that
+contains no handed over memory. Kexec then places the target kernel and initrd
+into that region. The new kernel exclusively uses this region for memory
+allocations before during boot up to the initialization of the page allocator.
+
+We guarantee that we always have such regions through the scratch regions: On
+first boot KHO allocates several physically contiguous memory regions. Since
+after kexec these regions will be used by early memory allocations, there is a
+scratch region per NUMA node plus a scratch region to satisfy allocations
+requests that do not require particular NUMA node assignment.
+By default, size of the scratch region is calculated based on amount of memory
+allocated during boot. The ``kho_scratch`` kernel command line option may be
+used to explicitly define size of the scratch regions.
+The scratch regions are declared as CMA when page allocator is initialized so
+that their memory can be used during system lifetime. CMA gives us the
+guarantee that no handover pages land in that region, because handover pages
+must be at a static physical memory location and CMA enforces that only
+movable pages can be located inside.
+
+After KHO kexec, we ignore the ``kho_scratch`` kernel command line option and
+instead reuse the exact same region that was originally allocated. This allows
+us to recursively execute any amount of KHO kexecs. Because we used this region
+for boot memory allocations and as target memory for kexec blobs, some parts
+of that memory region may be reserved. These reservations are irrelevant for
+the next KHO, because kexec can overwrite even the original kernel.
+
+.. _kho-finalization-phase:
+
+KHO finalization phase
+======================
+
+To enable user space based kexec file loader, the kernel needs to be able to
+provide the FDT that describes the current kernel's state before
+performing the actual kexec. The process of generating that FDT is
+called serialization. When the FDT is generated, some properties
+of the system may become immutable because they are already written down
+in the FDT. That state is called the KHO finalization phase.

+KHO FDT
+=======
+
+KHO uses the flattened device tree (FDT) container format and libfdt
+library to create and parse the data that is passed between the
+kernels. The properties in KHO FDT are stored in native format.
+It includes the physical address of an in-memory structure describing
+all preserved memory regions, as well as physical addresses of KHO users'
+own FDTs. Interpreting those sub FDTs is the responsibility of KHO users.
+
+KHO nodes and properties
+========================
+
+Property ``preserved-memory-map``
+---------------------------------
+
+KHO saves a special property named ``preserved-memory-map`` under the root node.
+This node contains the physical address of an in-memory structure for KHO to
+preserve memory regions across kexec.
+
+Property ``compatible``
+-----------------------
+
+The ``compatible`` property determines compatibility between the kernel
+that created the KHO FDT and the kernel that attempts to load it.
+If the kernel that loads the KHO FDT is not compatible with it, the entire
+KHO process will be bypassed.
+
+Property ``fdt``
+----------------
+
+Generally, a KHO user serialize its state into its own FDT and instructs
+KHO to preserve the underlying memory, such that after kexec, the new kernel
+can recover its state from the preserved FDT.
+
+A KHO user thus can create a node in KHO root tree and save the physical address
+of its own FDT in that node's property ``fdt`` .
+
+Examples
+========
+
+The following example demonstrates KHO FDT that preserves two memory
+regions created with ``reserve_mem`` kernel command line parameter::
+
+ /dts-v1/;
+
+ / {
+ compatible = "kho-v1";
+
+ preserved-memory-map = <0x40be16 0x1000000>;
+
+ memblock {
+ fdt = <0x1517 0x1000000>;
+ };
+ };
+
+where the ``memblock`` node contains an FDT that is requested by the
+subsystem memblock for preservation. The FDT contains the following
+serialized data::
+
+ /dts-v1/;
+
+ / {
+ compatible = "memblock-v1";
+
+ n1 {
+ compatible = "reserve-mem-v1";
+ start = <0xc06b 0x4000000>;
+ size = <0x04 0x00>;
+ };
+
+ n2 {
+ compatible = "reserve-mem-v1";
+ start = <0xc067 0x4000000>;
+ size = <0x04 0x00>;
+ };
+ };

+Linked Lists in Linux
+=====================
+
+:Author: Nicolas Frattaroli <nicolas.frattaroli@collabora.com>
+
+.. contents::
+
+Introduction
+============
+
+Linked lists are one of the most basic data structures used in many programs.
+The Linux kernel implements several different flavours of linked lists. The
+purpose of this document is not to explain linked lists in general, but to show
+new kernel developers how to use the Linux kernel implementations of linked
+lists.
+
+Please note that while linked lists certainly are ubiquitous, they are rarely
+the best data structure to use in cases where a simple array doesn't already
+suffice. In particular, due to their poor data locality, linked lists are a bad
+choice in situations where performance may be of consideration. Familiarizing
+oneself with other in-kernel generic data structures, especially for concurrent
+accesses, is highly encouraged.
+
+Linux implementation of doubly linked lists
+===========================================
+
+Linux's linked list implementations can be used by including the header file
+``<linux/list.h>``.
+
+The doubly-linked list will likely be the most familiar to many readers. It's a
+list that can efficiently be traversed forwards and backwards.
+
+The Linux kernel's doubly-linked list is circular in nature. This means that to
+get from the head node to the tail, we can just travel one edge backwards.
+Similarly, to get from the tail node to the head, we can simply travel forwards
+"beyond" the tail and arrive back at the head.
+
+Declaring a node
+----------------
+
+A node in a doubly-linked list is declared by adding a struct list_head
+member to the data structure you wish to be contained in the list:
+
+.. code-block:: c
+
+ struct clown {
+ unsigned long long shoe_size;
+ const char *name;
+ struct list_head node; /* the aforementioned member */
+ };
+
+This may be an unfamiliar approach to some, as the classical explanation of a
+linked list is a list node data structure with pointers to the previous and next
+list node, as well the payload data. Linux chooses this approach because it
+allows for generic list modification code regardless of what data structure is
+contained within the list. Since the struct list_head member is not a pointer
+but part of the data structure proper, the container_of() pattern can be used by
+the list implementation to access the payload data regardless of its type, while
+staying oblivious to what said type actually is.
+
+Declaring and initializing a list
+---------------------------------
+
+A doubly-linked list can then be declared as just another struct list_head,
+and initialized with the LIST_HEAD_INIT() macro during initial assignment, or
+with the INIT_LIST_HEAD() function later:
+
+.. code-block:: c
+
+ struct clown_car {
+ int tyre_pressure[4];
+ struct list_head clowns; /* Looks like a node! */
+ };
+
+ /* ... Somewhere later in our driver ... */
+
+ static int circus_init(struct circus_priv *circus)
+ {
+ struct clown_car other_car = {
+ .tyre_pressure = {10, 12, 11, 9},
+ .clowns = LIST_HEAD_INIT(other_car.clowns)
+ };
+
+ INIT_LIST_HEAD(&circus->car.clowns);
+
+ return 0;
+ }
+
+A further point of confusion to some may be that the list itself doesn't really
+have its own type. The concept of the entire linked list and a
+struct list_head member that points to other entries in the list are one and
+the same.
+
+Adding nodes to the list
+------------------------
+
+Adding a node to the linked list is done through the list_add() macro.
+
+We'll return to our clown car example to illustrate how nodes get added to the
+list:
+
+.. code-block:: c
+
+ static int circus_fill_car(struct circus_priv *circus)
+ {
+ struct clown_car *car = &circus->car;
+ struct clown *grock;
+ struct clown *dimitri;
+
+ /* State 1 */
+
+ grock = kzalloc(sizeof(*grock), GFP_KERNEL);
+ if (!grock)
+ return -ENOMEM;
+ grock->name = "Grock";
+ grock->shoe_size = 1000;
+
+ /* Note that we're adding the "node" member */
+ list_add(&grock->node, &car->clowns);
+
+ /* State 2 */
+
+ dimitri = kzalloc(sizeof(*dimitri), GFP_KERNEL);
+ if (!dimitri)
+ return -ENOMEM;
+ dimitri->name = "Dimitri";
+ dimitri->shoe_size = 50;
+
+ list_add(&dimitri->node, &car->clowns);
+
+ /* State 3 */
+
+ return 0;
+ }
+
+In State 1, our list of clowns is still empty::
+
+ .------.
+ v |
+ .--------. |
+ | clowns |--'
+ '--------'
+
+This diagram shows the singular "clowns" node pointing at itself. In this
+diagram, and all following diagrams, only the forward edges are shown, to aid in
+clarity.
+
+In State 2, we've added Grock after the list head::
+
+ .--------------------.
+ v |
+ .--------. .-------. |
+ | clowns |---->| Grock |--'
+ '--------' '-------'
+
+This diagram shows the "clowns" node pointing at a new node labeled "Grock".
+The Grock node is pointing back at the "clowns" node.
+
+In State 3, we've added Dimitri after the list head, resulting in the following::
+
+ .------------------------------------.
+ v |
+ .--------. .---------. .-------. |
+ | clowns |---->| Dimitri |---->| Grock |--'
+ '--------' '---------' '-------'
+
+This diagram shows the "clowns" node pointing at a new node labeled "Dimitri",
+which then points at the node labeled "Grock". The "Grock" node still points
+back at the "clowns" node.
+
+If we wanted to have Dimitri inserted at the end of the list instead, we'd use
+list_add_tail(). Our code would then look like this:
+
+.. code-block:: c
+
+ static int circus_fill_car(struct circus_priv *circus)
+ {
+ /* ... */
+
+ list_add_tail(&dimitri->node, &car->clowns);
+
+ /* State 3b */
+
+ return 0;
+ }
+
+This results in the following list::
+
+ .------------------------------------.
+ v |
+ .--------. .-------. .---------. |
+ | clowns |---->| Grock |---->| Dimitri |--'
+ '--------' '-------' '---------'
+
+This diagram shows the "clowns" node pointing at the node labeled "Grock",
+which points at the new node labeled "Dimitri". The node labeled "Dimitri"
+points back at the "clowns" node.
+
+Traversing the list
+-------------------
+
+To iterate the list, we can loop through all nodes within the list with
+list_for_each().
+
+In our clown example, this results in the following somewhat awkward code:
+
+.. code-block:: c
+
+ static unsigned long long circus_get_max_shoe_size(struct circus_priv *circus)
+ {
+ unsigned long long res = 0;
+ struct clown *e;
+ struct list_head *cur;
+
+ list_for_each(cur, &circus->car.clowns) {
+ e = list_entry(cur, struct clown, node);
+ if (e->shoe_size > res)
+ res = e->shoe_size;
+ }
+
+ return res;
+ }
+
+The list_entry() macro internally uses the aforementioned container_of() to
+retrieve the data structure instance that ``node`` is a member of.
+
+Note how the additional list_entry() call is a little awkward here. It's only
+there because we're iterating through the ``node`` members, but we really want
+to iterate through the payload, i.e. the ``struct clown`` that contains each
+node's struct list_head. For this reason, there is a second macro:
+list_for_each_entry()
+
+Using it would change our code to something like this:
+
+.. code-block:: c
+
+ static unsigned long long circus_get_max_shoe_size(struct circus_priv *circus)
+ {
+ unsigned long long res = 0;
+ struct clown *e;
+
+ list_for_each_entry(e, &circus->car.clowns, node) {
+ if (e->shoe_size > res)
+ res = e->shoe_size;
+ }
+
+ return res;
+ }
+
+This eliminates the need for the list_entry() step, and our loop cursor is now
+of the type of our payload. The macro is given the member name that corresponds
+to the list's struct list_head within the clown data structure so that it can
+still walk the list.
+
+Removing nodes from the list
+----------------------------
+
+The list_del() function can be used to remove entries from the list. It not only
+removes the given entry from the list, but poisons the entry's ``prev`` and
+``next`` pointers, so that unintended use of the entry after removal does not
+go unnoticed.
+
+We can extend our previous example to remove one of the entries:
+
+.. code-block:: c
+
+ static int circus_fill_car(struct circus_priv *circus)
+ {
+ /* ... */
+
+ list_add(&dimitri->node, &car->clowns);
+
+ /* State 3 */
+
+ list_del(&dimitri->node);
+
+ /* State 4 */
+
+ return 0;
+ }
+
+The result of this would be this::
+
+ .--------------------.
+ v |
+ .--------. .-------. | .---------.
+ | clowns |---->| Grock |--' | Dimitri |
+ '--------' '-------' '---------'
+
+This diagram shows the "clowns" node pointing at the node labeled "Grock",
+which points back at the "clowns" node. Off to the side is a lone node labeled
+"Dimitri", which has no arrows pointing anywhere.
+
+Note how the Dimitri node does not point to itself; its pointers are
+intentionally set to a "poison" value that the list code refuses to traverse.
+
+If we wanted to reinitialize the removed node instead to make it point at itself
+again like an empty list head, we can use list_del_init() instead:
+
+.. code-block:: c
+
+ static int circus_fill_car(struct circus_priv *circus)
+ {
+ /* ... */
+
+ list_add(&dimitri->node, &car->clowns);
+
+ /* State 3 */
+
+ list_del_init(&dimitri->node);
+
+ /* State 4b */
+
+ return 0;
+ }
+
+This results in the deleted node pointing to itself again::
+
+ .--------------------. .-------.
+ v | v |
+ .--------. .-------. | .---------. |
+ | clowns |---->| Grock |--' | Dimitri |--'
+ '--------' '-------' '---------'
+
+This diagram shows the "clowns" node pointing at the node labeled "Grock",
+which points back at the "clowns" node. Off to the side is a lone node labeled
+"Dimitri", which points to itself.
+
+Traversing whilst removing nodes
+--------------------------------
+
+Deleting entries while we're traversing the list will cause problems if we use
+list_for_each() and list_for_each_entry(), as deleting the current entry would
+modify the ``next`` pointer of it, which means the traversal can't properly
+advance to the next list entry.
+
+There is a solution to this however: list_for_each_safe() and
+list_for_each_entry_safe(). These take an additional parameter of a pointer to
+a struct list_head to use as temporary storage for the next entry during
+iteration, solving the issue.
+
+An example of how to use it:
+

+ list_for_each_entry_safe(e, n, &circus->car.clowns, node) {

+ list_del(&e->node);
+ }
+ }
+
+Proper memory management (i.e. freeing the deleted node while making sure
+nothing still references it) in this case is left as an exercise to the reader.
+
+Cutting a list
+--------------
+
+There are two helper functions to cut lists with. Both take elements from the
+list ``head``, and replace the contents of the list ``list``.
+
+The first such function is list_cut_position(). It removes all list entries from
+``head`` up to and including ``entry``, placing them in ``list`` instead.
+
+In this example, it's assumed we start with the following list::
+
+ .----------------------------------------------------------------.
+ v |
+ .--------. .-------. .---------. .-----. .---------. |
+ | clowns |---->| Grock |---->| Dimitri |---->| Pic |---->| Alfredo |--'
+ '--------' '-------' '---------' '-----' '---------'
+
+With the following code, every clown up to and including "Pic" is moved from
+the "clowns" list head to a separate struct list_head initialized at local
+stack variable ``retirement``:
+
+.. code-block:: c
+
+ static void circus_retire_clowns(struct circus_priv *circus)
+ {
+ struct list_head retirement = LIST_HEAD_INIT(retirement);
+ struct clown *grock, *dimitri, *pic, *alfredo;
+ struct clown_car *car = &circus->car;
+
+ /* ... clown initialization, list adding ... */
+
+ list_cut_position(&retirement, &car->clowns, &pic->node);
+
+ /* State 1 */
+ }
+
+The resulting ``car->clowns`` list would be this::
+
+ .----------------------.
+ v |
+ .--------. .---------. |
+ | clowns |---->| Alfredo |--'
+ '--------' '---------'
+
+Meanwhile, the ``retirement`` list is transformed to the following::
+
+ .--------------------------------------------------.
+ v |
+ .------------. .-------. .---------. .-----. |
+ | retirement |---->| Grock |---->| Dimitri |---->| Pic |--'
+ '------------' '-------' '---------' '-----'
+
+The second function, list_cut_before(), is much the same, except it cuts before
+the ``entry`` node, i.e. it removes all list entries from ``head`` up to but
+excluding ``entry``, placing them in ``list`` instead. This example assumes the
+same initial starting list as the previous example:
+
+.. code-block:: c
+
+ static void circus_retire_clowns(struct circus_priv *circus)
+ {
+ struct list_head retirement = LIST_HEAD_INIT(retirement);
+ struct clown *grock, *dimitri, *pic, *alfredo;
+ struct clown_car *car = &circus->car;
+
+ /* ... clown initialization, list adding ... */
+
+ list_cut_before(&retirement, &car->clowns, &pic->node);
+
+ /* State 1b */
+ }
+
+The resulting ``car->clowns`` list would be this::
+
+ .----------------------------------.
+ v |
+ .--------. .-----. .---------. |
+ | clowns |---->| Pic |---->| Alfredo |--'
+ '--------' '-----' '---------'
+
+Meanwhile, the ``retirement`` list is transformed to the following::
+
+ .--------------------------------------.
+ v |
+ .------------. .-------. .---------. |
+ | retirement |---->| Grock |---->| Dimitri |--'
+ '------------' '-------' '---------'
+
+It should be noted that both functions will destroy links to any existing nodes
+in the destination ``struct list_head *list``.
+
+Moving entries and partial lists
+--------------------------------
+
+The list_move() and list_move_tail() functions can be used to move an entry
+from one list to another, to either the start or end respectively.
+
+In the following example, we'll assume we start with two lists ("clowns" and
+"sidewalk" in the following initial state "State 0"::
+
+ .----------------------------------------------------------------.
+ v |
+ .--------. .-------. .---------. .-----. .---------. |
+ | clowns |---->| Grock |---->| Dimitri |---->| Pic |---->| Alfredo |--'
+ '--------' '-------' '---------' '-----' '---------'
+
+ .-------------------.
+ v |
+ .----------. .-----. |
+ | sidewalk |---->| Pio |--'
+ '----------' '-----'
+
+We apply the following example code to the two lists:
+
+.. code-block:: c
+
+ static void circus_clowns_exit_car(struct circus_priv *circus)
+ {
+ struct list_head sidewalk = LIST_HEAD_INIT(sidewalk);
+ struct clown *grock, *dimitri, *pic, *alfredo, *pio;
+ struct clown_car *car = &circus->car;
+
+ /* ... clown initialization, list adding ... */
+
+ /* State 0 */
+
+ list_move(&pic->node, &sidewalk);
+
+ /* State 1 */
+
+ list_move_tail(&dimitri->node, &sidewalk);
+
+ /* State 2 */
+ }
+
+In State 1, we arrive at the following situation::
+
+ .-----------------------------------------------------.
+ | |
+ v |
+ .--------. .-------. .---------. .---------. |
+ | clowns |---->| Grock |---->| Dimitri |---->| Alfredo |--'
+ '--------' '-------' '---------' '---------'
+
+ .-------------------------------.
+ v |
+ .----------. .-----. .-----. |
+ | sidewalk |---->| Pic |---->| Pio |--'
+ '----------' '-----' '-----'
+
+In State 2, after we've moved Dimitri to the tail of sidewalk, the situation
+changes as follows::
+
+ .-------------------------------------.
+ | |
+ v |
+ .--------. .-------. .---------. |
+ | clowns |---->| Grock |---->| Alfredo |--'
+ '--------' '-------' '---------'
+
+ .-----------------------------------------------.
+ v |
+ .----------. .-----. .-----. .---------. |
+ | sidewalk |---->| Pic |---->| Pio |---->| Dimitri |--'
+ '----------' '-----' '-----' '---------'
+
+As long as the source and destination list head are part of the same list, we
+can also efficiently bulk move a segment of the list to the tail end of the
+list. We continue the previous example by adding a list_bulk_move_tail() after
+State 2, moving Pic and Pio to the tail end of the sidewalk list.
+
+.. code-block:: c
+
+ static void circus_clowns_exit_car(struct circus_priv *circus)
+ {
+ struct list_head sidewalk = LIST_HEAD_INIT(sidewalk);
+ struct clown *grock, *dimitri, *pic, *alfredo, *pio;
+ struct clown_car *car = &circus->car;
+
+ /* ... clown initialization, list adding ... */
+
+ /* State 0 */
+
+ list_move(&pic->node, &sidewalk);
+
+ /* State 1 */
+
+ list_move_tail(&dimitri->node, &sidewalk);
+
+ /* State 2 */
+
+ list_bulk_move_tail(&sidewalk, &pic->node, &pio->node);
+
+ /* State 3 */
+ }
+
+For the sake of brevity, only the altered "sidewalk" list at State 3 is depicted
+in the following diagram::
+
+ .-----------------------------------------------.
+ v |
+ .----------. .---------. .-----. .-----. |
+ | sidewalk |---->| Dimitri |---->| Pic |---->| Pio |--'
+ '----------' '---------' '-----' '-----'
+
+Do note that list_bulk_move_tail() does not do any checking as to whether all
+three supplied ``struct list_head *`` parameters really do belong to the same
+list. If you use it outside the constraints the documentation gives, then the
+result is a matter between you and the implementation.
+
+Rotating entries
+----------------
+
+A common write operation on lists, especially when using them as queues, is
+to rotate it. A list rotation means entries at the front are sent to the back.
+
+For rotation, Linux provides us with two functions: list_rotate_left() and
+list_rotate_to_front(). The former can be pictured like a bicycle chain, taking
+the entry after the supplied ``struct list_head *`` and moving it to the tail,
+which in essence means the entire list, due to its circular nature, rotates by
+one position.
+
+The latter, list_rotate_to_front(), takes the same concept one step further:
+instead of advancing the list by one entry, it advances it *until* the specified
+entry is the new front.
+
+In the following example, our starting state, State 0, is the following::
+
+ .-----------------------------------------------------------------.
+ v |
+ .--------. .-------. .---------. .-----. .---------. .-----. |
+ | clowns |-->| Grock |-->| Dimitri |-->| Pic |-->| Alfredo |-->| Pio |-'
+ '--------' '-------' '---------' '-----' '---------' '-----'
+
+The example code being used to demonstrate list rotations is the following:
+
+.. code-block:: c
+
+ static void circus_clowns_rotate(struct circus_priv *circus)
+ {
+ struct clown *grock, *dimitri, *pic, *alfredo, *pio;
+ struct clown_car *car = &circus->car;
+
+ /* ... clown initialization, list adding ... */
+
+ /* State 0 */
+
+ list_rotate_left(&car->clowns);
+
+ /* State 1 */
+
+ list_rotate_to_front(&alfredo->node, &car->clowns);
+
+ /* State 2 */
+
+ }
+
+In State 1, we arrive at the following situation::
+
+ .-----------------------------------------------------------------.
+ v |
+ .--------. .---------. .-----. .---------. .-----. .-------. |
+ | clowns |-->| Dimitri |-->| Pic |-->| Alfredo |-->| Pio |-->| Grock |-'
+ '--------' '---------' '-----' '---------' '-----' '-------'
+
+Next, after the list_rotate_to_front() call, we arrive in the following
+State 2::
+
+ .-----------------------------------------------------------------.
+ v |
+ .--------. .---------. .-----. .-------. .---------. .-----. |
+ | clowns |-->| Alfredo |-->| Pio |-->| Grock |-->| Dimitri |-->| Pic |-'
+ '--------' '---------' '-----' '-------' '---------' '-----'
+
+As is hopefully evident from the diagrams, the entries in front of "Alfredo"
+were cycled to the tail end of the list.
+
+Swapping entries
+----------------
+
+Another common operation is that two entries need to be swapped with each other.
+
+For this, Linux provides us with list_swap().
+
+In the following example, we have a list with three entries, and swap two of
+them. This is our starting state in "State 0"::
+
+ .-----------------------------------------.
+ v |
+ .--------. .-------. .---------. .-----. |
+ | clowns |-->| Grock |-->| Dimitri |-->| Pic |-'
+ '--------' '-------' '---------' '-----'
+
+.. code-block:: c
+
+ static void circus_clowns_swap(struct circus_priv *circus)
+ {
+ struct clown *grock, *dimitri, *pic;
+ struct clown_car *car = &circus->car;
+
+ /* ... clown initialization, list adding ... */
+
+ /* State 0 */
+
+ list_swap(&dimitri->node, &pic->node);
+
+ /* State 1 */
+ }
+
+The resulting list at State 1 is the following::
+
+ .-----------------------------------------.
+ v |
+ .--------. .-------. .-----. .---------. |
+ | clowns |-->| Grock |-->| Pic |-->| Dimitri |-'
+ '--------' '-------' '-----' '---------'
+
+As is evident by comparing the diagrams, the "Pic" and "Dimitri" nodes have
+traded places.
+
+Splicing two lists together
+---------------------------
+
+Say we have two lists, in the following example one represented by a list head
+we call "knie" and one we call "stey". In a hypothetical circus acquisition,
+the two list of clowns should be spliced together. The following is our
+situation in "State 0"::
+
+ .-----------------------------------------.
+ | |
+ v |
+ .------. .-------. .---------. .-----. |
+ | knie |-->| Grock |-->| Dimitri |-->| Pic |--'
+ '------' '-------' '---------' '-----'
+
+ .-----------------------------.
+ v |
+ .------. .---------. .-----. |
+ | stey |-->| Alfredo |-->| Pio |--'
+ '------' '---------' '-----'
+
+The function to splice these two lists together is list_splice(). Our example
+code is as follows:
+
+.. code-block:: c
+
+ static void circus_clowns_splice(void)
+ {
+ struct clown *grock, *dimitri, *pic, *alfredo, *pio;
+ struct list_head knie = LIST_HEAD_INIT(knie);
+ struct list_head stey = LIST_HEAD_INIT(stey);
+
+ /* ... Clown allocation and initialization here ... */
+
+ list_add_tail(&grock->node, &knie);
+ list_add_tail(&dimitri->node, &knie);
+ list_add_tail(&pic->node, &knie);
+ list_add_tail(&alfredo->node, &stey);
+ list_add_tail(&pio->node, &stey);
+
+ /* State 0 */
+
+ list_splice(&stey, &dimitri->node);
+
+ /* State 1 */
+ }
+
+The list_splice() call here adds all the entries in ``stey`` to the list
+``dimitri``'s ``node`` list_head is in, after the ``node`` of ``dimitri``. A
+somewhat surprising diagram of the resulting "State 1" follows::
+
+ .-----------------------------------------------------------------.
+ | |
+ v |
+ .------. .-------. .---------. .---------. .-----. .-----. |
+ | knie |-->| Grock |-->| Dimitri |-->| Alfredo |-->| Pio |-->| Pic |--'
+ '------' '-------' '---------' '---------' '-----' '-----'
+ ^
+ .-------------------------------'
+ |
+ .------. |
+ | stey |--'
+ '------'
+
+Traversing the ``stey`` list no longer results in correct behavior. A call of
+list_for_each() on ``stey`` results in an infinite loop, as it never returns
+back to the ``stey`` list head.
+
+This is because list_splice() did not reinitialize the list_head it took
+entries from, leaving its pointer pointing into what is now a different list.
+
+If we want to avoid this situation, list_splice_init() can be used. It does the
+same thing as list_splice(), except reinitalizes the donor list_head after the
+transplant.
+
+Concurrency considerations
+--------------------------
+
+Concurrent access and modification of a list needs to be protected with a lock
+in most cases. Alternatively and preferably, one may use the RCU primitives for
+lists in read-mostly use-cases, where read accesses to the list are common but
+modifications to the list less so. See Documentation/RCU/listRCU.rst for more
+details.

+Introduction

+
+The Min Heap API provides a set of functions and macros for managing min-heaps
+in the Linux kernel. A min-heap is a binary tree structure where the value of
+each node is less than or equal to the values of its children, ensuring that
+the smallest element is always at the root.
+
+This document provides a guide to the Min Heap API, detailing how to define and
+use min-heaps. Users should not directly call functions with **__min_heap_*()**
+prefixes, but should instead use the provided macro wrappers.
+
+In addition to the standard version of the functions, the API also includes a
+set of inline versions for performance-critical scenarios. These inline
+functions have the same names as their non-inline counterparts but include an
+**_inline** suffix. For example, **__min_heap_init_inline** and its
+corresponding macro wrapper **min_heap_init_inline**. The inline versions allow
+custom comparison and swap functions to be called directly, rather than through
+indirect function calls. This can significantly reduce overhead, especially
+when CONFIG_MITIGATION_RETPOLINE is enabled, as indirect function calls become
+more expensive. As with the non-inline versions, it is important to use the
+macro wrappers for inline functions instead of directly calling the functions
+themselves.
+
+Data Structures
+===============
+
+Min-Heap Definition
+-------------------
+
+The core data structure for representing a min-heap is defined using the
+**MIN_HEAP_PREALLOCATED** and **DEFINE_MIN_HEAP** macros. These macros allow
+you to define a min-heap with a preallocated buffer or dynamically allocated
+memory.
+
+Example:
+
+.. code-block:: c
+
+ #define MIN_HEAP_PREALLOCATED(_type, _name, _nr)
+ struct _name {
+ size_t nr; /* Number of elements in the heap */
+ size_t size; /* Maximum number of elements that can be held */
+ _type *data; /* Pointer to the heap data */
+ _type preallocated[_nr]; /* Static preallocated array */
+ }
+
+ #define DEFINE_MIN_HEAP(_type, _name) MIN_HEAP_PREALLOCATED(_type, _name, 0)
+
+A typical heap structure will include a counter for the number of elements
+(`nr`), the maximum capacity of the heap (`size`), and a pointer to an array of
+elements (`data`). Optionally, you can specify a static array for preallocated
+heap storage using **MIN_HEAP_PREALLOCATED**.
+
+Min Heap Callbacks
+------------------
+
+The **struct min_heap_callbacks** provides customization options for ordering
+elements in the heap and swapping them. It contains two function pointers:
+
+.. code-block:: c
+
+ struct min_heap_callbacks {
+ bool (*less)(const void *lhs, const void *rhs, void *args);
+ void (*swp)(void *lhs, void *rhs, void *args);
+ };
+
+- **less** is the comparison function used to establish the order of elements.
+- **swp** is a function for swapping elements in the heap. If swp is set to
+ NULL, the default swap function will be used, which swaps the elements based on their size
+
+Macro Wrappers
+==============
+
+The following macro wrappers are provided for interacting with the heap in a
+user-friendly manner. Each macro corresponds to a function that operates on the
+heap, and they abstract away direct calls to internal functions.
+
+Each macro accepts various parameters that are detailed below.
+
+Heap Initialization
+--------------------
+
+.. code-block:: c
+
+ min_heap_init(heap, data, size);
+
+- **heap**: A pointer to the min-heap structure to be initialized.
+- **data**: A pointer to the buffer where the heap elements will be stored. If
+ `NULL`, the preallocated buffer within the heap structure will be used.
+- **size**: The maximum number of elements the heap can hold.
+
+This macro initializes the heap, setting its initial state. If `data` is
+`NULL`, the preallocated memory inside the heap structure will be used for
+storage. Otherwise, the user-provided buffer is used. The operation is **O(1)**.
+
+**Inline Version:** min_heap_init_inline(heap, data, size)
+
+Accessing the Top Element
+-------------------------
+
+.. code-block:: c
+
+ element = min_heap_peek(heap);
+
+- **heap**: A pointer to the min-heap from which to retrieve the smallest
+ element.
+
+This macro returns a pointer to the smallest element (the root) of the heap, or
+`NULL` if the heap is empty. The operation is **O(1)**.
+
+**Inline Version:** min_heap_peek_inline(heap)
+
+Heap Insertion
+--------------
+
+.. code-block:: c
+
+ success = min_heap_push(heap, element, callbacks, args);
+
+- **heap**: A pointer to the min-heap into which the element should be inserted.
+- **element**: A pointer to the element to be inserted into the heap.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+ `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro inserts an element into the heap. It returns `true` if the insertion
+was successful and `false` if the heap is full. The operation is **O(log n)**.
+
+**Inline Version:** min_heap_push_inline(heap, element, callbacks, args)
+
+Heap Removal
+------------
+
+.. code-block:: c
+
+ success = min_heap_pop(heap, callbacks, args);
+
+- **heap**: A pointer to the min-heap from which to remove the smallest element.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+ `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro removes the smallest element (the root) from the heap. It returns
+`true` if the element was successfully removed, or `false` if the heap is
+empty. The operation is **O(log n)**.
+
+**Inline Version:** min_heap_pop_inline(heap, callbacks, args)
+
+Heap Maintenance
+----------------
+
+You can use the following macros to maintain the heap's structure:
+
+.. code-block:: c
+
+ min_heap_sift_down(heap, pos, callbacks, args);
+
+- **heap**: A pointer to the min-heap.
+- **pos**: The index from which to start sifting down.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+ `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro restores the heap property by moving the element at the specified
+index (`pos`) down the heap until it is in the correct position. The operation
+is **O(log n)**.
+
+**Inline Version:** min_heap_sift_down_inline(heap, pos, callbacks, args)
+
+.. code-block:: c
+
+ min_heap_sift_up(heap, idx, callbacks, args);
+
+- **heap**: A pointer to the min-heap.
+- **idx**: The index of the element to sift up.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+ `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro restores the heap property by moving the element at the specified
+index (`idx`) up the heap. The operation is **O(log n)**.
+
+**Inline Version:** min_heap_sift_up_inline(heap, idx, callbacks, args)
+
+.. code-block:: c
+
+ min_heapify_all(heap, callbacks, args);
+
+- **heap**: A pointer to the min-heap.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+ `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro ensures that the entire heap satisfies the heap property. It is
+called when the heap is built from scratch or after many modifications. The
+operation is **O(n)**.
+
+**Inline Version:** min_heapify_all_inline(heap, callbacks, args)
+
+Removing Specific Elements
+--------------------------
+
+.. code-block:: c
+
+ success = min_heap_del(heap, idx, callbacks, args);
+
+- **heap**: A pointer to the min-heap.
+- **idx**: The index of the element to delete.
+- **callbacks**: A pointer to a `struct min_heap_callbacks` providing the
+ `less` and `swp` functions.
+- **args**: Optional arguments passed to the `less` and `swp` functions.
+
+This macro removes an element at the specified index (`idx`) from the heap and
+restores the heap property. The operation is **O(log n)**.
+
+**Inline Version:** min_heap_del_inline(heap, idx, callbacks, args)
+
+Other Utilities
+===============
+
+- **min_heap_full(heap)**: Checks whether the heap is full.
+ Complexity: **O(1)**.
+
+.. code-block:: c
+
+ bool full = min_heap_full(heap);
+
+- `heap`: A pointer to the min-heap to check.
+
+This macro returns `true` if the heap is full, otherwise `false`.
+
+**Inline Version:** min_heap_full_inline(heap)
+
+- **min_heap_empty(heap)**: Checks whether the heap is empty.
+ Complexity: **O(1)**.

+
+**Inline Version:** min_heap_empty_inline(heap)
+
+Example Usage
+=============
+
+An example usage of the min-heap API would involve defining a heap structure,
+initializing it, and inserting and removing elements as needed.
+
+.. code-block:: c
+
+ #include <linux/min_heap.h>
+
+ int my_less_function(const void *lhs, const void *rhs, void *args) {
+ return (*(int *)lhs < *(int *)rhs);
+ }
+
+ struct min_heap_callbacks heap_cb = {
+ .less = my_less_function, /* Comparison function for heap order */
+ .swp = NULL, /* Use default swap function */
+ };
+
+ void example_usage(void) {
+ /* Pre-populate the buffer with elements */
+ int buffer[5] = {5, 2, 8, 1, 3};
+ /* Declare a min-heap */
+ DEFINE_MIN_HEAP(int, my_heap);
+
+ /* Initialize the heap with preallocated buffer and size */
+ min_heap_init(&my_heap, buffer, 5);
+
+ /* Build the heap using min_heapify_all */
+ my_heap.nr = 5; /* Set the number of elements in the heap */
+ min_heapify_all(&my_heap, &heap_cb, NULL);
+
+ /* Peek at the top element (should be 1 in this case) */
+ int *top = min_heap_peek(&my_heap);
+ pr_info("Top element: %d\n", *top);
+
+ /* Pop the top element (1) and get the new top (2) */
+ min_heap_pop(&my_heap, &heap_cb, NULL);
+ top = min_heap_peek(&my_heap);
+ pr_info("New top element: %d\n", *top);
+
+ /* Insert a new element (0) and recheck the top */
+ int new_element = 0;
+ min_heap_push(&my_heap, &new_element, &heap_cb, NULL);
+ top = min_heap_peek(&my_heap);
+ pr_info("Top element after insertion: %d\n", *top);
+ }

We always think of our offsets as if there were no quirk, and we translate
them afterwards, before accessing the memory region.
+Note on buffer lengths not multiple of 4
+----------------------------------------
+
+To deal with memory layout quirks where groups of 4 bytes are laid out "little
+endian" relative to each other, but "big endian" within the group itself, the
+concept of groups of 4 bytes is intrinsic to the packing API (not to be
+confused with the memory access, which is performed byte by byte, though).
+
+With buffer lengths not multiple of 4, this means one group will be incomplete.
+Depending on the quirks, this may lead to discontinuities in the bit fields

+the intention of the memory layout, so it avoids them by effectively logically
+shortening the most significant group of 4 octets to the number of octets
+actually available.
+

+describes.
+
+There are 3 supported usage patterns, detailed below.
+
+packing()
+^^^^^^^^^
+
+This API function is deprecated.
The packing() function returns an int-encoded error code, which protects the
programmer against incorrect API use. The errors are not expected to occur
-during runtime, therefore it is reasonable for xxx_packing() to return void
-and simply swallow those errors. Optionally it can dump stack or print the

+during runtime, therefore it is reasonable to wrap packing() into a custom

+
+.. code-block:: c

+ {
+ int err;
+
+ /* Adjust quirks accordingly */

+ return;

+ startbit, endbit);
+ else
+ pr_err("Cannot store %llx inside bits %d-%d (would truncate)\n",
+ *val, startbit, endbit);
+ }
+ dump_stack();
+ }
+
+pack() and unpack()
+^^^^^^^^^^^^^^^^^^^
+
+These are const-correct variants of packing(), and eliminate the last "enum
+packing_op op" argument.
+
+Calling pack(...) is equivalent, and preferred, to calling packing(..., PACK).
+
+Calling unpack(...) is equivalent, and preferred, to calling packing(..., UNPACK).
+
+pack_fields() and unpack_fields()
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The library exposes optimized functions for the scenario where there are many
+fields represented in a buffer, and it encourages consumer drivers to avoid
+repetitive calls to pack() and unpack() for each field, but instead use
+pack_fields() and unpack_fields(), which reduces the code footprint.
+
+These APIs use field definitions in arrays of ``struct packed_field_u8`` or
+``struct packed_field_u16``, allowing consumer drivers to minimize the size
+of these arrays according to their custom requirements.
+
+The pack_fields() and unpack_fields() API functions are actually macros which
+automatically select the appropriate function at compile time, based on the
+type of the fields array passed in.
+
+An additional benefit over pack() and unpack() is that sanity checks on the
+field definitions are handled at compile time with ``BUILD_BUG_ON`` rather
+than only when the offending code is executed. These functions return void and
+wrapping them to handle unexpected errors is not necessary.
+
+It is recommended, but not required, that you wrap your packed buffer into a
+structured type with a fixed size. This generally makes it easier for the
+compiler to enforce that the correct size buffer is used.
+
+Here is an example of how to use the fields APIs:
+
+.. code-block:: c
+
+ /* Ordering inside the unpacked structure is flexible and can be different
+ * from the packed buffer. Here, it is optimized to reduce padding.
+ */
+ struct data {
+ u64 field3;
+ u32 field4;
+ u16 field1;
+ u8 field2;
+ };
+
+ #define SIZE 13
+
+ typedef struct __packed { u8 buf[SIZE]; } packed_buf_t;
+
+ static const struct packed_field_u8 fields[] = {
+ PACKED_FIELD(100, 90, struct data, field1),
+ PACKED_FIELD(90, 87, struct data, field2),
+ PACKED_FIELD(86, 30, struct data, field3),
+ PACKED_FIELD(29, 0, struct data, field4),
+ };
+
+ void unpack_your_data(const packed_buf_t *buf, struct data *unpacked)
+ {
+ BUILD_BUG_ON(sizeof(*buf) != SIZE;
+
+ unpack_fields(buf, sizeof(*buf), unpacked, fields,
+ QUIRK_LITTLE_ENDIAN);
+ }
+
+ void pack_your_data(const struct data *unpacked, packed_buf_t *buf)
+ {
+ BUILD_BUG_ON(sizeof(*buf) != SIZE;
+
+ pack_fields(buf, sizeof(*buf), unpacked, fields,
+ QUIRK_LITTLE_ENDIAN);
+ }

+=============================================
+Porting an architecture to support PREEMPT_RT
+=============================================
+
+:Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+
+This list outlines the architecture specific requirements that must be
+implemented in order to enable PREEMPT_RT. Once all required features are
+implemented, ARCH_SUPPORTS_RT can be selected in architecture’s Kconfig to make
+PREEMPT_RT selectable.
+Many prerequisites (genirq support for example) are enforced by the common code
+and are omitted here.
+
+The optional features are not strictly required but it is worth to consider
+them.
+
+Requirements
+------------
+
+Forced threaded interrupts
+ CONFIG_IRQ_FORCED_THREADING must be selected. Any interrupts that must
+ remain in hard-IRQ context must be marked with IRQF_NO_THREAD. This
+ requirement applies for instance to clocksource event interrupts,
+ perf interrupts and cascading interrupt-controller handlers.
+
+PREEMPTION support
+ Kernel preemption must be supported and requires that
+ CONFIG_ARCH_NO_PREEMPT remain unselected. Scheduling requests, such as those
+ issued from an interrupt or other exception handler, must be processed
+ immediately.
+
+POSIX CPU timers and KVM
+ POSIX CPU timers must expire from thread context rather than directly within
+ the timer interrupt. This behavior is enabled by setting the configuration
+ option CONFIG_HAVE_POSIX_CPU_TIMERS_TASK_WORK.
+ When KVM is enabled, CONFIG_KVM_XFER_TO_GUEST_WORK must also be set to ensure
+ that any pending work, such as POSIX timer expiration, is handled before
+ transitioning into guest mode.
+
+Hard-IRQ and Soft-IRQ stacks
+ Soft interrupts are handled in the thread context in which they are raised. If
+ a soft interrupt is triggered from hard-IRQ context, its execution is deferred
+ to the ksoftirqd thread. Preemption is never disabled during soft interrupt
+ handling, which makes soft interrupts preemptible.
+ If an architecture provides a custom __do_softirq() implementation that uses a
+ separate stack, it must select CONFIG_HAVE_SOFTIRQ_ON_OWN_STACK. The
+ functionality should only be enabled when CONFIG_SOFTIRQ_ON_OWN_STACK is set.
+
+FPU and SIMD access in kernel mode
+ FPU and SIMD registers are typically not used in kernel mode and are therefore
+ not saved during kernel preemption. As a result, any kernel code that uses
+ these registers must be enclosed within a kernel_fpu_begin() and
+ kernel_fpu_end() section.
+ The kernel_fpu_begin() function usually invokes local_bh_disable() to prevent
+ interruptions from softirqs and to disable regular preemption. This allows the
+ protected code to run safely in both thread and softirq contexts.
+ On PREEMPT_RT kernels, however, kernel_fpu_begin() must not call
+ local_bh_disable(). Instead, it should use preempt_disable(), since softirqs
+ are always handled in thread context under PREEMPT_RT. In this case, disabling
+ preemption alone is sufficient.
+ The crypto subsystem operates on memory pages and requires users to "walk and
+ map" these pages while processing a request. This operation must occur outside
+ the kernel_fpu_begin()/ kernel_fpu_end() section because it requires preemption
+ to be enabled. These preemption points are generally sufficient to avoid
+ excessive scheduling latency.
+
+Exception handlers
+ Exception handlers, such as the page fault handler, typically enable interrupts
+ early, before invoking any generic code to process the exception. This is
+ necessary because handling a page fault may involve operations that can sleep.
+ Enabling interrupts is especially important on PREEMPT_RT, where certain
+ locks, such as spinlock_t, become sleepable. For example, handling an
+ invalid opcode may result in sending a SIGILL signal to the user task. A
+ debug excpetion will send a SIGTRAP signal.
+ In both cases, if the exception occurred in user space, it is safe to enable
+ interrupts early. Sending a signal requires both interrupts and kernel
+ preemption to be enabled.
+
+Optional features
+-----------------
+
+Timer and clocksource
+ A high-resolution clocksource and clockevents device are recommended. The
+ clockevents device should support the CLOCK_EVT_FEAT_ONESHOT feature for
+ optimal timer behavior. In most cases, microsecond-level accuracy is
+ sufficient
+
+Lazy preemption
+ This mechanism allows an in-kernel scheduling request for non-real-time tasks
+ to be delayed until the task is about to return to user space. It helps avoid
+ preempting a task that holds a sleeping lock at the time of the scheduling
+ request.
+ With CONFIG_GENERIC_IRQ_ENTRY enabled, supporting this feature requires
+ defining a bit for TIF_NEED_RESCHED_LAZY, preferably near TIF_NEED_RESCHED.
+
+Serial console with NBCON
+ With PREEMPT_RT enabled, all console output is handled by a dedicated thread
+ rather than directly from the context in which printk() is invoked. This design
+ allows printk() to be safely used in atomic contexts.
+ However, this also means that if the kernel crashes and cannot switch to the
+ printing thread, no output will be visible preventing the system from printing
+ its final messages.
+ There are exceptions for immediate output, such as during panic() handling. To
+ support this, the console driver must implement new-style lock handling. This
+ involves setting the CON_NBCON flag in console::flags and providing
+ implementations for the write_atomic, write_thread, device_lock, and
+ device_unlock callbacks.

+===========================
+How realtime kernels differ
+===========================
+
+:Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+
+Preface
+=======
+
+With forced-threaded interrupts and sleeping spin locks, code paths that
+previously caused long scheduling latencies have been made preemptible and
+moved into process context. This allows the scheduler to manage them more
+effectively and respond to higher-priority tasks with reduced latency.
+
+The following chapters provide an overview of key differences between a
+PREEMPT_RT kernel and a standard, non-PREEMPT_RT kernel.
+
+Locking
+=======
+
+Spinning locks such as spinlock_t are used to provide synchronization for data
+structures accessed from both interrupt context and process context. For this
+reason, locking functions are also available with the _irq() or _irqsave()
+suffixes, which disable interrupts before acquiring the lock. This ensures that
+the lock can be safely acquired in process context when interrupts are enabled.
+
+However, on a PREEMPT_RT system, interrupts are forced-threaded and no longer
+run in hard IRQ context. As a result, there is no need to disable interrupts as
+part of the locking procedure when using spinlock_t.
+
+For low-level core components such as interrupt handling, the scheduler, or the
+timer subsystem the kernel uses raw_spinlock_t. This lock type preserves
+traditional semantics: it disables preemption and, when used with _irq() or
+_irqsave(), also disables interrupts. This ensures proper synchronization in
+critical sections that must remain non-preemptible or with interrupts disabled.
+
+Execution context
+=================
+
+Interrupt handling in a PREEMPT_RT system is invoked in process context through
+the use of threaded interrupts. Other parts of the kernel also shift their
+execution into threaded context by different mechanisms. The goal is to keep
+execution paths preemptible, allowing the scheduler to interrupt them when a
+higher-priority task needs to run.
+
+Below is an overview of the kernel subsystems involved in this transition to
+threaded, preemptible execution.
+
+Interrupt handling
+------------------
+
+All interrupts are forced-threaded in a PREEMPT_RT system. The exceptions are
+interrupts that are requested with the IRQF_NO_THREAD, IRQF_PERCPU, or
+IRQF_ONESHOT flags.
+
+The IRQF_ONESHOT flag is used together with threaded interrupts, meaning those
+registered using request_threaded_irq() and providing only a threaded handler.
+Its purpose is to keep the interrupt line masked until the threaded handler has
+completed.
+
+If a primary handler is also provided in this case, it is essential that the
+handler does not acquire any sleeping locks, as it will not be threaded. The
+handler should be minimal and must avoid introducing delays, such as
+busy-waiting on hardware registers.
+
+
+Soft interrupts, bottom half handling
+-------------------------------------
+
+Soft interrupts are raised by the interrupt handler and are executed after the
+handler returns. Since they run in thread context, they can be preempted by
+other threads. Do not assume that softirq context runs with preemption
+disabled. This means you must not rely on mechanisms like local_bh_disable() in
+process context to protect per-CPU variables. Because softirq handlers are
+preemptible under PREEMPT_RT, this approach does not provide reliable
+synchronization.
+
+If this kind of protection is required for performance reasons, consider using
+local_lock_nested_bh(). On non-PREEMPT_RT kernels, this allows lockdep to
+verify that bottom halves are disabled. On PREEMPT_RT systems, it adds the
+necessary locking to ensure proper protection.
+
+Using local_lock_nested_bh() also makes the locking scope explicit and easier
+for readers and maintainers to understand.
+
+
+per-CPU variables
+-----------------
+
+Protecting access to per-CPU variables solely by using preempt_disable() should
+be avoided, especially if the critical section has unbounded runtime or may
+call APIs that can sleep.
+
+If using a spinlock_t is considered too costly for performance reasons,
+consider using local_lock_t. On non-PREEMPT_RT configurations, this introduces
+no runtime overhead when lockdep is disabled. With lockdep enabled, it verifies
+that the lock is only acquired in process context and never from softirq or
+hard IRQ context.
+
+On a PREEMPT_RT kernel, local_lock_t is implemented using a per-CPU spinlock_t,
+which provides safe local protection for per-CPU data while keeping the system
+preemptible.
+
+Because spinlock_t on PREEMPT_RT does not disable preemption, it cannot be used
+to protect per-CPU data by relying on implicit preemption disabling. If this
+inherited preemption disabling is essential and if local_lock_t cannot be used
+due to performance constraints, brevity of the code, or abstraction boundaries
+within an API then preempt_disable_nested() may be a suitable alternative. On
+non-PREEMPT_RT kernels, it verifies with lockdep that preemption is already
+disabled. On PREEMPT_RT, it explicitly disables preemption.
+
+Timers
+------
+
+By default, an hrtimer is executed in hard interrupt context. The exception is
+timers initialized with the HRTIMER_MODE_SOFT flag, which are executed in
+softirq context.
+
+On a PREEMPT_RT kernel, this behavior is reversed: hrtimers are executed in
+softirq context by default, typically within the ktimersd thread. This thread
+runs at the lowest real-time priority, ensuring it executes before any
+SCHED_OTHER tasks but does not interfere with higher-priority real-time
+threads. To explicitly request execution in hard interrupt context on
+PREEMPT_RT, the timer must be marked with the HRTIMER_MODE_HARD flag.
+
+Memory allocation
+-----------------
+
+The memory allocation APIs, such as kmalloc() and alloc_pages(), require a
+gfp_t flag to indicate the allocation context. On non-PREEMPT_RT kernels, it is
+necessary to use GFP_ATOMIC when allocating memory from interrupt context or
+from sections where preemption is disabled. This is because the allocator must
+not sleep in these contexts waiting for memory to become available.
+
+However, this approach does not work on PREEMPT_RT kernels. The memory
+allocator in PREEMPT_RT uses sleeping locks internally, which cannot be
+acquired when preemption is disabled. Fortunately, this is generally not a
+problem, because PREEMPT_RT moves most contexts that would traditionally run
+with preemption or interrupts disabled into threaded context, where sleeping is
+allowed.
+
+What remains problematic is code that explicitly disables preemption or
+interrupts. In such cases, memory allocation must be performed outside the
+critical section.
+
+This restriction also applies to memory deallocation routines such as kfree()
+and free_pages(), which may also involve internal locking and must not be
+called from non-preemptible contexts.
+
+IRQ work
+--------
+
+The irq_work API provides a mechanism to schedule a callback in interrupt
+context. It is designed for use in contexts where traditional scheduling is not
+possible, such as from within NMI handlers or from inside the scheduler, where
+using a workqueue would be unsafe.
+
+On non-PREEMPT_RT systems, all irq_work items are executed immediately in
+interrupt context. Items marked with IRQ_WORK_LAZY are deferred until the next
+timer tick but are still executed in interrupt context.
+
+On PREEMPT_RT systems, the execution model changes. Because irq_work callbacks
+may acquire sleeping locks or have unbounded execution time, they are handled
+in thread context by a per-CPU irq_work kernel thread. This thread runs at the
+lowest real-time priority, ensuring it executes before any SCHED_OTHER tasks
+but does not interfere with higher-priority real-time threads.
+
+The exception are work items marked with IRQ_WORK_HARD_IRQ, which are still
+executed in hard interrupt context. Lazy items (IRQ_WORK_LAZY) continue to be
+deferred until the next timer tick and are also executed by the irq_work/
+thread.
+
+RCU callbacks
+-------------
+
+RCU callbacks are invoked by default in softirq context. Their execution is
+important because, depending on the use case, they either free memory or ensure
+progress in state transitions. Running these callbacks as part of the softirq
+chain can lead to undesired situations, such as contention for CPU resources
+with other SCHED_OTHER tasks when executed within ksoftirqd.
+
+To avoid running callbacks in softirq context, the RCU subsystem provides a
+mechanism to execute them in process context instead. This behavior can be
+enabled by setting the boot command-line parameter rcutree.use_softirq=0. This
+setting is enforced in kernels configured with PREEMPT_RT.
+
+Spin until ready
+================
+
+The "spin until ready" pattern involves repeatedly checking (spinning on) the
+state of a data structure until it becomes available. This pattern assumes that
+preemption, soft interrupts, or interrupts are disabled. If the data structure
+is marked busy, it is presumed to be in use by another CPU, and spinning should
+eventually succeed as that CPU makes progress.
+
+Some examples are hrtimer_cancel() or timer_delete_sync(). These functions
+cancel timers that execute with interrupts or soft interrupts disabled. If a
+thread attempts to cancel a timer and finds it active, spinning until the
+callback completes is safe because the callback can only run on another CPU and
+will eventually finish.
+
+On PREEMPT_RT kernels, however, timer callbacks run in thread context. This
+introduces a challenge: a higher-priority thread attempting to cancel the timer
+may preempt the timer callback thread. Since the scheduler cannot migrate the
+callback thread to another CPU due to affinity constraints, spinning can result
+in livelock even on multiprocessor systems.
+
+To avoid this, both the canceling and callback sides must use a handshake
+mechanism that supports priority inheritance. This allows the canceling thread
+to suspend until the callback completes, ensuring forward progress without
+risking livelock.
+
+In order to solve the problem at the API level, the sequence locks were extended
+to allow a proper handover between the the spinning reader and the maybe
+blocked writer.
+
+Sequence locks
+--------------
+
+Sequence counters and sequential locks are documented in
+Documentation/locking/seqlock.rst.
+
+The interface has been extended to ensure proper preemption states for the
+writer and spinning reader contexts. This is achieved by embedding the writer
+serialization lock directly into the sequence counter type, resulting in
+composite types such as seqcount_spinlock_t or seqcount_mutex_t.
+
+These composite types allow readers to detect an ongoing write and actively
+boost the writer’s priority to help it complete its update instead of spinning
+and waiting for its completion.
+
+If the plain seqcount_t is used, extra care must be taken to synchronize the
+reader with the writer during updates. The writer must ensure its update is
+serialized and non-preemptible relative to the reader. This cannot be achieved
+using a regular spinlock_t because spinlock_t on PREEMPT_RT does not disable
+preemption. In such cases, using seqcount_spinlock_t is the preferred solution.
+
+However, if there is no spinning involved i.e., if the reader only needs to
+detect whether a write has started and not serialize against it then using
+seqcount_t is reasonable.

+=====================
+Theory of operation
+=====================
+
+:Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+
+Preface
+=======
+
+PREEMPT_RT transforms the Linux kernel into a real-time kernel. It achieves
+this by replacing locking primitives, such as spinlock_t, with a preemptible
+and priority-inheritance aware implementation known as rtmutex, and by enforcing
+the use of threaded interrupts. As a result, the kernel becomes fully
+preemptible, with the exception of a few critical code paths, including entry
+code, the scheduler, and low-level interrupt handling routines.
+
+This transformation places the majority of kernel execution contexts under the
+control of the scheduler and significantly increasing the number of preemption
+points. Consequently, it reduces the latency between a high-priority task
+becoming runnable and its actual execution on the CPU.
+
+Scheduling
+==========
+
+The core principles of Linux scheduling and the associated user-space API are
+documented in the man page sched(7)
+`sched(7) <https://man7.org/linux/man-pages/man7/sched.7.html>`_.
+By default, the Linux kernel uses the SCHED_OTHER scheduling policy. Under
+this policy, a task is preempted when the scheduler determines that it has
+consumed a fair share of CPU time relative to other runnable tasks. However,
+the policy does not guarantee immediate preemption when a new SCHED_OTHER task
+becomes runnable. The currently running task may continue executing.
+
+This behavior differs from that of real-time scheduling policies such as
+SCHED_FIFO. When a task with a real-time policy becomes runnable, the
+scheduler immediately selects it for execution if it has a higher priority than
+the currently running task. The task continues to run until it voluntarily
+yields the CPU, typically by blocking on an event.
+
+Sleeping spin locks
+===================
+
+The various lock types and their behavior under real-time configurations are
+described in detail in Documentation/locking/locktypes.rst.
+In a non-PREEMPT_RT configuration, a spinlock_t is acquired by first disabling
+preemption and then actively spinning until the lock becomes available. Once
+the lock is released, preemption is enabled. From a real-time perspective,
+this approach is undesirable because disabling preemption prevents the
+scheduler from switching to a higher-priority task, potentially increasing
+latency.
+
+To address this, PREEMPT_RT replaces spinning locks with sleeping spin locks
+that do not disable preemption. On PREEMPT_RT, spinlock_t is implemented using
+rtmutex. Instead of spinning, a task attempting to acquire a contended lock
+disables CPU migration, donates its priority to the lock owner (priority
+inheritance), and voluntarily schedules out while waiting for the lock to
+become available.
+
+Disabling CPU migration provides the same effect as disabling preemption, while
+still allowing preemption and ensuring that the task continues to run on the
+same CPU while holding a sleeping lock.
+
+Priority inheritance
+====================
+
+Lock types such as spinlock_t and mutex_t in a PREEMPT_RT enabled kernel are
+implemented on top of rtmutex, which provides support for priority inheritance
+(PI). When a task blocks on such a lock, the PI mechanism temporarily
+propagates the blocked task’s scheduling parameters to the lock owner.
+
+For example, if a SCHED_FIFO task A blocks on a lock currently held by a
+SCHED_OTHER task B, task A’s scheduling policy and priority are temporarily
+inherited by task B. After this inheritance, task A is put to sleep while
+waiting for the lock, and task B effectively becomes the highest-priority task
+in the system. This allows B to continue executing, make progress, and
+eventually release the lock.
+
+Once B releases the lock, it reverts to its original scheduling parameters, and
+task A can resume execution.
+
+Threaded interrupts
+===================
+
+Interrupt handlers are another source of code that executes with preemption
+disabled and outside the control of the scheduler. To bring interrupt handling
+under scheduler control, PREEMPT_RT enforces threaded interrupt handlers.
+
+With forced threading, interrupt handling is split into two stages. The first
+stage, the primary handler, is executed in IRQ context with interrupts disabled.
+Its sole responsibility is to wake the associated threaded handler. The second
+stage, the threaded handler, is the function passed to request_irq() as the
+interrupt handler. It runs in process context, scheduled by the kernel.
+
+From waking the interrupt thread until threaded handling is completed, the
+interrupt source is masked in the interrupt controller. This ensures that the
+device interrupt remains pending but does not retrigger the CPU, allowing the
+system to exit IRQ context and handle the interrupt in a scheduled thread.
+
+By default, the threaded handler executes with the SCHED_FIFO scheduling policy
+and a priority of 50 (MAX_RT_PRIO / 2), which is midway between the minimum and
+maximum real-time priorities.
+
+If the threaded interrupt handler raises any soft interrupts during its
+execution, those soft interrupt routines are invoked after the threaded handler
+completes, within the same thread. Preemption remains enabled during the
+execution of the soft interrupt handler.
+
+Summary
+=======
+
+By using sleeping locks and forced-threaded interrupts, PREEMPT_RT
+significantly reduces sections of code where interrupts or preemption is
+disabled, allowing the scheduler to preempt the current execution context and
+switch to a higher-priority task.

+===============
+DMA and swiotlb
+===============
+
+swiotlb is a memory buffer allocator used by the Linux kernel DMA layer. It is
+typically used when a device doing DMA can't directly access the target memory
+buffer because of hardware limitations or other requirements. In such a case,
+the DMA layer calls swiotlb to allocate a temporary memory buffer that conforms
+to the limitations. The DMA is done to/from this temporary memory buffer, and
+the CPU copies the data between the temporary buffer and the original target
+memory buffer. This approach is generically called "bounce buffering", and the
+temporary memory buffer is called a "bounce buffer".
+
+Device drivers don't interact directly with swiotlb. Instead, drivers inform
+the DMA layer of the DMA attributes of the devices they are managing, and use
+the normal DMA map, unmap, and sync APIs when programming a device to do DMA.
+These APIs use the device DMA attributes and kernel-wide settings to determine
+if bounce buffering is necessary. If so, the DMA layer manages the allocation,
+freeing, and sync'ing of bounce buffers. Since the DMA attributes are per
+device, some devices in a system may use bounce buffering while others do not.
+
+Because the CPU copies data between the bounce buffer and the original target
+memory buffer, doing bounce buffering is slower than doing DMA directly to the
+original memory buffer, and it consumes more CPU resources. So it is used only
+when necessary for providing DMA functionality.
+
+Usage Scenarios
+---------------
+swiotlb was originally created to handle DMA for devices with addressing
+limitations. As physical memory sizes grew beyond 4 GiB, some devices could
+only provide 32-bit DMA addresses. By allocating bounce buffer memory below
+the 4 GiB line, these devices with addressing limitations could still work and
+do DMA.
+
+More recently, Confidential Computing (CoCo) VMs have the guest VM's memory
+encrypted by default, and the memory is not accessible by the host hypervisor
+and VMM. For the host to do I/O on behalf of the guest, the I/O must be
+directed to guest memory that is unencrypted. CoCo VMs set a kernel-wide option
+to force all DMA I/O to use bounce buffers, and the bounce buffer memory is set
+up as unencrypted. The host does DMA I/O to/from the bounce buffer memory, and
+the Linux kernel DMA layer does "sync" operations to cause the CPU to copy the
+data to/from the original target memory buffer. The CPU copying bridges between
+the unencrypted and the encrypted memory. This use of bounce buffers allows
+device drivers to "just work" in a CoCo VM, with no modifications
+needed to handle the memory encryption complexity.
+
+Other edge case scenarios arise for bounce buffers. For example, when IOMMU
+mappings are set up for a DMA operation to/from a device that is considered
+"untrusted", the device should be given access only to the memory containing
+the data being transferred. But if that memory occupies only part of an IOMMU
+granule, other parts of the granule may contain unrelated kernel data. Since
+IOMMU access control is per-granule, the untrusted device can gain access to
+the unrelated kernel data. This problem is solved by bounce buffering the DMA
+operation and ensuring that unused portions of the bounce buffers do not
+contain any unrelated kernel data.
+
+Core Functionality
+------------------
+The primary swiotlb APIs are swiotlb_tbl_map_single() and
+swiotlb_tbl_unmap_single(). The "map" API allocates a bounce buffer of a
+specified size in bytes and returns the physical address of the buffer. The
+buffer memory is physically contiguous. The expectation is that the DMA layer
+maps the physical memory address to a DMA address, and returns the DMA address
+to the driver for programming into the device. If a DMA operation specifies
+multiple memory buffer segments, a separate bounce buffer must be allocated for
+each segment. swiotlb_tbl_map_single() always does a "sync" operation (i.e., a
+CPU copy) to initialize the bounce buffer to match the contents of the original
+buffer.
+
+swiotlb_tbl_unmap_single() does the reverse. If the DMA operation might have
+updated the bounce buffer memory and DMA_ATTR_SKIP_CPU_SYNC is not set, the
+unmap does a "sync" operation to cause a CPU copy of the data from the bounce
+buffer back to the original buffer. Then the bounce buffer memory is freed.
+
+swiotlb also provides "sync" APIs that correspond to the dma_sync_*() APIs that
+a driver may use when control of a buffer transitions between the CPU and the
+device. The swiotlb "sync" APIs cause a CPU copy of the data between the
+original buffer and the bounce buffer. Like the dma_sync_*() APIs, the swiotlb
+"sync" APIs support doing a partial sync, where only a subset of the bounce
+buffer is copied to/from the original buffer.
+
+Core Functionality Constraints
+------------------------------
+The swiotlb map/unmap/sync APIs must operate without blocking, as they are
+called by the corresponding DMA APIs which may run in contexts that cannot
+block. Hence the default memory pool for swiotlb allocations must be
+pre-allocated at boot time (but see Dynamic swiotlb below). Because swiotlb
+allocations must be physically contiguous, the entire default memory pool is
+allocated as a single contiguous block.
+
+The need to pre-allocate the default swiotlb pool creates a boot-time tradeoff.
+The pool should be large enough to ensure that bounce buffer requests can
+always be satisfied, as the non-blocking requirement means requests can't wait
+for space to become available. But a large pool potentially wastes memory, as
+this pre-allocated memory is not available for other uses in the system. The
+tradeoff is particularly acute in CoCo VMs that use bounce buffers for all DMA
+I/O. These VMs use a heuristic to set the default pool size to ~6% of memory,
+with a max of 1 GiB, which has the potential to be very wasteful of memory.
+Conversely, the heuristic might produce a size that is insufficient, depending
+on the I/O patterns of the workload in the VM. The dynamic swiotlb feature
+described below can help, but has limitations. Better management of the swiotlb
+default memory pool size remains an open issue.
+
+A single allocation from swiotlb is limited to IO_TLB_SIZE * IO_TLB_SEGSIZE
+bytes, which is 256 KiB with current definitions. When a device's DMA settings
+are such that the device might use swiotlb, the maximum size of a DMA segment
+must be limited to that 256 KiB. This value is communicated to higher-level
+kernel code via dma_map_mapping_size() and swiotlb_max_mapping_size(). If the
+higher-level code fails to account for this limit, it may make requests that
+are too large for swiotlb, and get a "swiotlb full" error.
+
+A key device DMA setting is "min_align_mask", which is a power of 2 minus 1
+so that some number of low order bits are set, or it may be zero. swiotlb
+allocations ensure these min_align_mask bits of the physical address of the
+bounce buffer match the same bits in the address of the original buffer. When
+min_align_mask is non-zero, it may produce an "alignment offset" in the address
+of the bounce buffer that slightly reduces the maximum size of an allocation.
+This potential alignment offset is reflected in the value returned by
+swiotlb_max_mapping_size(), which can show up in places like
+/sys/block/<device>/queue/max_sectors_kb. For example, if a device does not use
+swiotlb, max_sectors_kb might be 512 KiB or larger. If a device might use
+swiotlb, max_sectors_kb will be 256 KiB. When min_align_mask is non-zero,
+max_sectors_kb might be even smaller, such as 252 KiB.
+
+swiotlb_tbl_map_single() also takes an "alloc_align_mask" parameter. This
+parameter specifies the allocation of bounce buffer space must start at a
+physical address with the alloc_align_mask bits set to zero. But the actual
+bounce buffer might start at a larger address if min_align_mask is non-zero.
+Hence there may be pre-padding space that is allocated prior to the start of
+the bounce buffer. Similarly, the end of the bounce buffer is rounded up to an
+alloc_align_mask boundary, potentially resulting in post-padding space. Any
+pre-padding or post-padding space is not initialized by swiotlb code. The
+"alloc_align_mask" parameter is used by IOMMU code when mapping for untrusted
+devices. It is set to the granule size - 1 so that the bounce buffer is
+allocated entirely from granules that are not used for any other purpose.
+
+Data structures concepts
+------------------------
+Memory used for swiotlb bounce buffers is allocated from overall system memory
+as one or more "pools". The default pool is allocated during system boot with a
+default size of 64 MiB. The default pool size may be modified with the
+"swiotlb=" kernel boot line parameter. The default size may also be adjusted
+due to other conditions, such as running in a CoCo VM, as described above. If
+CONFIG_SWIOTLB_DYNAMIC is enabled, additional pools may be allocated later in
+the life of the system. Each pool must be a contiguous range of physical
+memory. The default pool is allocated below the 4 GiB physical address line so
+it works for devices that can only address 32-bits of physical memory (unless
+architecture-specific code provides the SWIOTLB_ANY flag). In a CoCo VM, the
+pool memory must be decrypted before swiotlb is used.
+
+Each pool is divided into "slots" of size IO_TLB_SIZE, which is 2 KiB with
+current definitions. IO_TLB_SEGSIZE contiguous slots (128 slots) constitute
+what might be called a "slot set". When a bounce buffer is allocated, it
+occupies one or more contiguous slots. A slot is never shared by multiple
+bounce buffers. Furthermore, a bounce buffer must be allocated from a single
+slot set, which leads to the maximum bounce buffer size being IO_TLB_SIZE *
+IO_TLB_SEGSIZE. Multiple smaller bounce buffers may co-exist in a single slot
+set if the alignment and size constraints can be met.
+
+Slots are also grouped into "areas", with the constraint that a slot set exists
+entirely in a single area. Each area has its own spin lock that must be held to
+manipulate the slots in that area. The division into areas avoids contending
+for a single global spin lock when swiotlb is heavily used, such as in a CoCo
+VM. The number of areas defaults to the number of CPUs in the system for
+maximum parallelism, but since an area can't be smaller than IO_TLB_SEGSIZE
+slots, it might be necessary to assign multiple CPUs to the same area. The
+number of areas can also be set via the "swiotlb=" kernel boot parameter.
+
+When allocating a bounce buffer, if the area associated with the calling CPU
+does not have enough free space, areas associated with other CPUs are tried
+sequentially. For each area tried, the area's spin lock must be obtained before
+trying an allocation, so contention may occur if swiotlb is relatively busy
+overall. But an allocation request does not fail unless all areas do not have
+enough free space.
+
+IO_TLB_SIZE, IO_TLB_SEGSIZE, and the number of areas must all be powers of 2 as
+the code uses shifting and bit masking to do many of the calculations. The
+number of areas is rounded up to a power of 2 if necessary to meet this
+requirement.
+
+The default pool is allocated with PAGE_SIZE alignment. If an alloc_align_mask
+argument to swiotlb_tbl_map_single() specifies a larger alignment, one or more
+initial slots in each slot set might not meet the alloc_align_mask criterium.
+Because a bounce buffer allocation can't cross a slot set boundary, eliminating
+those initial slots effectively reduces the max size of a bounce buffer.
+Currently, there's no problem because alloc_align_mask is set based on IOMMU
+granule size, and granules cannot be larger than PAGE_SIZE. But if that were to
+change in the future, the initial pool allocation might need to be done with
+alignment larger than PAGE_SIZE.
+
+Dynamic swiotlb
+---------------
+When CONFIG_SWIOTLB_DYNAMIC is enabled, swiotlb can do on-demand expansion of
+the amount of memory available for allocation as bounce buffers. If a bounce
+buffer request fails due to lack of available space, an asynchronous background
+task is kicked off to allocate memory from general system memory and turn it
+into an swiotlb pool. Creating an additional pool must be done asynchronously
+because the memory allocation may block, and as noted above, swiotlb requests
+are not allowed to block. Once the background task is kicked off, the bounce
+buffer request creates a "transient pool" to avoid returning an "swiotlb full"
+error. A transient pool has the size of the bounce buffer request, and is
+deleted when the bounce buffer is freed. Memory for this transient pool comes
+from the general system memory atomic pool so that creation does not block.
+Creating a transient pool has relatively high cost, particularly in a CoCo VM
+where the memory must be decrypted, so it is done only as a stopgap until the
+background task can add another non-transient pool.
+
+Adding a dynamic pool has limitations. Like with the default pool, the memory
+must be physically contiguous, so the size is limited to MAX_PAGE_ORDER pages
+(e.g., 4 MiB on a typical x86 system). Due to memory fragmentation, a max size
+allocation may not be available. The dynamic pool allocator tries smaller sizes
+until it succeeds, but with a minimum size of 1 MiB. Given sufficient system
+memory fragmentation, dynamically adding a pool might not succeed at all.
+
+The number of areas in a dynamic pool may be different from the number of areas
+in the default pool. Because the new pool size is typically a few MiB at most,
+the number of areas will likely be smaller. For example, with a new pool size
+of 4 MiB and the 256 KiB minimum area size, only 16 areas can be created. If
+the system has more than 16 CPUs, multiple CPUs must share an area, creating
+more lock contention.
+
+New pools added via dynamic swiotlb are linked together in a linear list.
+swiotlb code frequently must search for the pool containing a particular
+swiotlb physical address, so that search is linear and not performant with a
+large number of dynamic pools. The data structures could be improved for
+faster searches.
+
+Overall, dynamic swiotlb works best for small configurations with relatively
+few CPUs. It allows the default swiotlb pool to be smaller so that memory is
+not wasted, with dynamic pools making more space available if needed (as long
+as fragmentation isn't an obstacle). It is less useful for large CoCo VMs.
+
+Data Structure Details
+----------------------
+swiotlb is managed with four primary data structures: io_tlb_mem, io_tlb_pool,
+io_tlb_area, and io_tlb_slot. io_tlb_mem describes a swiotlb memory allocator,
+which includes the default memory pool and any dynamic or transient pools
+linked to it. Limited statistics on swiotlb usage are kept per memory allocator
+and are stored in this data structure. These statistics are available under
+/sys/kernel/debug/swiotlb when CONFIG_DEBUG_FS is set.
+
+io_tlb_pool describes a memory pool, either the default pool, a dynamic pool,
+or a transient pool. The description includes the start and end addresses of
+the memory in the pool, a pointer to an array of io_tlb_area structures, and a
+pointer to an array of io_tlb_slot structures that are associated with the pool.
+
+io_tlb_area describes an area. The primary field is the spin lock used to
+serialize access to slots in the area. The io_tlb_area array for a pool has an
+entry for each area, and is accessed using a 0-based area index derived from the
+calling processor ID. Areas exist solely to allow parallel access to swiotlb
+from multiple CPUs.
+
+io_tlb_slot describes an individual memory slot in the pool, with size
+IO_TLB_SIZE (2 KiB currently). The io_tlb_slot array is indexed by the slot
+index computed from the bounce buffer address relative to the starting memory
+address of the pool. The size of struct io_tlb_slot is 24 bytes, so the
+overhead is about 1% of the slot size.
+
+The io_tlb_slot array is designed to meet several requirements. First, the DMA
+APIs and the corresponding swiotlb APIs use the bounce buffer address as the
+identifier for a bounce buffer. This address is returned by
+swiotlb_tbl_map_single(), and then passed as an argument to
+swiotlb_tbl_unmap_single() and the swiotlb_sync_*() functions. The original
+memory buffer address obviously must be passed as an argument to
+swiotlb_tbl_map_single(), but it is not passed to the other APIs. Consequently,
+swiotlb data structures must save the original memory buffer address so that it
+can be used when doing sync operations. This original address is saved in the
+io_tlb_slot array.
+
+Second, the io_tlb_slot array must handle partial sync requests. In such cases,
+the argument to swiotlb_sync_*() is not the address of the start of the bounce
+buffer but an address somewhere in the middle of the bounce buffer, and the
+address of the start of the bounce buffer isn't known to swiotlb code. But
+swiotlb code must be able to calculate the corresponding original memory buffer
+address to do the CPU copy dictated by the "sync". So an adjusted original
+memory buffer address is populated into the struct io_tlb_slot for each slot
+occupied by the bounce buffer. An adjusted "alloc_size" of the bounce buffer is
+also recorded in each struct io_tlb_slot so a sanity check can be performed on
+the size of the "sync" operation. The "alloc_size" field is not used except for
+the sanity check.
+
+Third, the io_tlb_slot array is used to track available slots. The "list" field
+in struct io_tlb_slot records how many contiguous available slots exist starting
+at that slot. A "0" indicates that the slot is occupied. A value of "1"
+indicates only the current slot is available. A value of "2" indicates the
+current slot and the next slot are available, etc. The maximum value is
+IO_TLB_SEGSIZE, which can appear in the first slot in a slot set, and indicates
+that the entire slot set is available. These values are used when searching for
+available slots to use for a new bounce buffer. They are updated when allocating
+a new bounce buffer and when freeing a bounce buffer. At pool creation time, the
+"list" field is initialized to IO_TLB_SEGSIZE down to 1 for the slots in every
+slot set.
+
+Fourth, the io_tlb_slot array keeps track of any "padding slots" allocated to
+meet alloc_align_mask requirements described above. When
+swiotlb_tbl_map_single() allocates bounce buffer space to meet alloc_align_mask
+requirements, it may allocate pre-padding space across zero or more slots. But
+when swiotlb_tbl_unmap_single() is called with the bounce buffer address, the
+alloc_align_mask value that governed the allocation, and therefore the
+allocation of any padding slots, is not known. The "pad_slots" field records
+the number of padding slots so that swiotlb_tbl_unmap_single() can free them.
+The "pad_slots" value is recorded only in the first non-padding slot allocated
+to the bounce buffer.
+
+Restricted pools
+----------------
+The swiotlb machinery is also used for "restricted pools", which are pools of
+memory separate from the default swiotlb pool, and that are dedicated for DMA
+use by a particular device. Restricted pools provide a level of DMA memory
+protection on systems with limited hardware protection capabilities, such as
+those lacking an IOMMU. Such usage is specified by DeviceTree entries and
+requires that CONFIG_DMA_RESTRICTED_POOL is set. Each restricted pool is based
+on its own io_tlb_mem data structure that is independent of the main swiotlb
+io_tlb_mem.
+
+Restricted pools add swiotlb_alloc() and swiotlb_free() APIs, which are called
+from the dma_alloc_*() and dma_free_*() APIs. The swiotlb_alloc/free() APIs

+Union-Find in Linux
+====================

+:Date: June 21, 2024

+
+What is union-find, and what is it used for?
+------------------------------------------------
+
+Union-find is a data structure used to handle the merging and querying
+of disjoint sets. The primary operations supported by union-find are:
+
+ Initialization: Resetting each element as an individual set, with
+ each set's initial parent node pointing to itself.
+
+ Find: Determine which set a particular element belongs to, usually by
+ returning a “representative element” of that set. This operation
+ is used to check if two elements are in the same set.
+
+ Union: Merge two sets into one.
+
+As a data structure used to maintain sets (groups), union-find is commonly
+utilized to solve problems related to offline queries, dynamic connectivity,
+and graph theory. It is also a key component in Kruskal's algorithm for
+computing the minimum spanning tree, which is crucial in scenarios like
+network routing. Consequently, union-find is widely referenced. Additionally,
+union-find has applications in symbolic computation, register allocation,
+and more.
+
+Space Complexity: O(n), where n is the number of nodes.
+
+Time Complexity: Using path compression can reduce the time complexity of
+the find operation, and using union by rank can reduce the time complexity
+of the union operation. These optimizations reduce the average time
+complexity of each find and union operation to O(α(n)), where α(n) is the
+inverse Ackermann function. This can be roughly considered a constant time
+complexity for practical purposes.
+
+This document covers use of the Linux union-find implementation. For more
+information on the nature and implementation of union-find, see:
+
+ Wikipedia entry on union-find
+ https://en.wikipedia.org/wiki/Disjoint-set_data_structure
+
+Linux implementation of union-find
+-----------------------------------
+
+Linux's union-find implementation resides in the file "lib/union_find.c".
+To use it, "#include <linux/union_find.h>".
+
+The union-find data structure is defined as follows::
+
+ struct uf_node {
+ struct uf_node *parent;
+ unsigned int rank;
+ };
+
+In this structure, parent points to the parent node of the current node.
+The rank field represents the height of the current tree. During a union
+operation, the tree with the smaller rank is attached under the tree with the
+larger rank to maintain balance.
+
+Initializing union-find
+-----------------------
+
+You can complete the initialization using either static or initialization
+interface. Initialize the parent pointer to point to itself and set the rank
+to 0.
+Example::
+
+ struct uf_node my_node = UF_INIT_NODE(my_node);
+
+or
+
+ uf_node_init(&my_node);
+
+Find the Root Node of union-find
+--------------------------------
+
+This operation is mainly used to determine whether two nodes belong to the same
+set in the union-find. If they have the same root, they are in the same set.
+During the find operation, path compression is performed to improve the
+efficiency of subsequent find operations.
+Example::
+
+ int connected;
+ struct uf_node *root1 = uf_find(&node_1);
+ struct uf_node *root2 = uf_find(&node_2);
+ if (root1 == root2)
+ connected = 1;
+ else
+ connected = 0;
+
+Union Two Sets in union-find
+----------------------------
+
+To union two sets in the union-find, you first find their respective root nodes
+and then link the smaller node to the larger node based on the rank of the root
+nodes.
+Example::
+
+ uf_union(&node_1, &node_2);

+Affinity Scopes
+===============
+
+An unbound workqueue groups CPUs according to its affinity scope to improve
+cache locality. For example, if a workqueue is using the default affinity
+scope of "cache", it will group CPUs according to last level cache
+boundaries. A work item queued on the workqueue will be assigned to a worker
+on one of the CPUs which share the last level cache with the issuing CPU.
+Once started, the worker may or may not be allowed to move outside the scope
+depending on the ``affinity_strict`` setting of the scope.
+
+Workqueue currently supports the following affinity scopes.
+
+``default``
+ Use the scope in module parameter ``workqueue.default_affinity_scope``
+ which is always set to one of the scopes below.
+
+``cpu``
+ CPUs are not grouped. A work item issued on one CPU is processed by a
+ worker on the same CPU. This makes unbound workqueues behave as per-cpu
+ workqueues without concurrency management.
+
+``smt``
+ CPUs are grouped according to SMT boundaries. This usually means that the
+ logical threads of each physical CPU core are grouped together.
+
+``cache``
+ CPUs are grouped according to cache boundaries. Which specific cache
+ boundary is used is determined by the arch code. L3 is used in a lot of
+ cases. This is the default affinity scope.
+
+``numa``
+ CPUs are grouped according to NUMA boundaries.
+
+``system``
+ All CPUs are put in the same group. Workqueue makes no effort to process a
+ work item on a CPU close to the issuing CPU.
+
+The default affinity scope can be changed with the module parameter
+``workqueue.default_affinity_scope`` and a specific workqueue's affinity
+scope can be changed using ``apply_workqueue_attrs()``.
+
+If ``WQ_SYSFS`` is set, the workqueue will have the following affinity scope
+related interface files under its ``/sys/devices/virtual/workqueue/WQ_NAME/``
+directory.
+
+``affinity_scope``
+ Read to see the current affinity scope. Write to change.
+
+ When default is the current scope, reading this file will also show the
+ current effective scope in parentheses, for example, ``default (cache)``.
+
+``affinity_strict``
+ 0 by default indicating that affinity scopes are not strict. When a work
+ item starts execution, workqueue makes a best-effort attempt to ensure
+ that the worker is inside its affinity scope, which is called
+ repatriation. Once started, the scheduler is free to move the worker
+ anywhere in the system as it sees fit. This enables benefiting from scope
+ locality while still being able to utilize other CPUs if necessary and
+ available.
+
+ If set to 1, all workers of the scope are guaranteed always to be in the
+ scope. This may be useful when crossing affinity scopes has other
+ implications, for example, in terms of power consumption or workload
+ isolation. Strict NUMA scope can also be used to match the workqueue
+ behavior of older kernels.
+
+
+Affinity Scopes and Performance
+===============================
+
+It'd be ideal if an unbound workqueue's behavior is optimal for vast
+majority of use cases without further tuning. Unfortunately, in the current
+kernel, there exists a pronounced trade-off between locality and utilization
+necessitating explicit configurations when workqueues are heavily used.
+
+Higher locality leads to higher efficiency where more work is performed for
+the same number of consumed CPU cycles. However, higher locality may also
+cause lower overall system utilization if the work items are not spread
+enough across the affinity scopes by the issuers. The following performance
+testing with dm-crypt clearly illustrates this trade-off.
+
+The tests are run on a CPU with 12-cores/24-threads split across four L3
+caches (AMD Ryzen 9 3900x). CPU clock boost is turned off for consistency.
+``/dev/dm-0`` is a dm-crypt device created on NVME SSD (Samsung 990 PRO) and
+opened with ``cryptsetup`` with default settings.
+
+
+Scenario 1: Enough issuers and work spread across the machine

+ --iodepth=64 --runtime=60 --numjobs=24 --time_based --group_reporting \
+ --name=iops-test-job --verify=sha512
+
+There are 24 issuers, each issuing 64 IOs concurrently. ``--verify=sha512``
+makes ``fio`` generate and read back the content each time which makes
+execution locality matter between the issuer and ``kcryptd``. The following
+are the read bandwidths and CPU utilizations depending on different affinity
+scope settings on ``kcryptd`` measured over five runs. Bandwidths are in
+MiBps, and CPU util in percents.

+ - 99.34 ±0.01
+
+ * - cache (strict)
+ - 1166.00 ±0.71
+ - 99.35 ±0.01
+
+With enough issuers spread across the system, there is no downside to
+"cache", strict or otherwise. All three configurations saturate the whole
+machine but the cache-affine ones outperform by 0.6% thanks to improved
+locality.
+
+
+Scenario 2: Fewer issuers, enough work for saturation
+-----------------------------------------------------
+
+The command used: ::
+

+ --ioengine=libaio --iodepth=64 --runtime=60 --numjobs=8 \
+ --time_based --group_reporting --name=iops-test-job --verify=sha512
+
+The only difference from the previous scenario is ``--numjobs=8``. There are
+a third of the issuers but is still enough total work to saturate the
+system.

+ - 96.15 ±0.09
+
+ * - cache (strict)
+ - 1112.00 ±4.64
+ - 93.26 ±0.35
+
+This is more than enough work to saturate the system. Both "system" and
+"cache" are nearly saturating the machine but not fully. "cache" is using
+less CPU but the better efficiency puts it at the same bandwidth as
+"system".
+
+Eight issuers moving around over four L3 cache scope still allow "cache
+(strict)" to mostly saturate the machine but the loss of work conservation
+is now starting to hurt with 3.7% bandwidth loss.

+Again, the only difference is ``--numjobs=4``. With the number of issuers
+reduced to four, there now isn't enough work to saturate the whole system
+and the bandwidth becomes dependent on completion latencies.

+
+Now, the tradeoff between locality and utilization is clearer. "cache" shows
+2% bandwidth loss compared to "system" and "cache (struct)" whopping 20%.
+
+
+Conclusion and Recommendations
+------------------------------
+
+In the above experiments, the efficiency advantage of the "cache" affinity
+scope over "system" is, while consistent and noticeable, small. However, the
+impact is dependent on the distances between the scopes and may be more
+pronounced in processors with more complex topologies.
+
+While the loss of work-conservation in certain scenarios hurts, it is a lot
+better than "cache (strict)" and maximizing workqueue utilization is
+unlikely to be the common case anyway. As such, "cache" is the default
+affinity scope for unbound pools.
+
+* As there is no one option which is great for most cases, workqueue usages
+ that may consume a significant amount of CPU are recommended to configure
+ the workqueues using ``apply_workqueue_attrs()`` and/or enable
+ ``WQ_SYSFS``.
+
+* An unbound workqueue with strict "cpu" affinity scope behaves the same as
+ ``WQ_CPU_INTENSIVE`` per-cpu workqueue. There is no real advanage to the
+ latter and an unbound workqueue provides a lot more flexibility.
+
+* Affinity scopes are introduced in Linux v6.5. To emulate the previous
+ behavior, use strict "numa" affinity scope.
+
+* The loss of work-conservation in non-strict affinity scopes is likely
+ originating from the scheduler. There is no theoretical reason why the
+ kernel wouldn't be able to do the right thing and maintain
+ work-conservation in most cases. As such, it is possible that future
+ scheduler improvements may make most of these tunables unnecessary.

+
+Small Buffer
+------------
+
+To pass small pieces of data about, such as keys, a buffer structure is
+defined, giving a pointer to the data and the size of that data::
+
+ struct krb5_buffer {
+ unsigned int len;
+ void *data;
+ };
+
+Encoding Type
+=============
+
+The encoding type is defined by the following structure::
+
+ struct krb5_enctype {
+ int etype;
+ int ctype;
+ const char *name;
+ u16 key_bytes;
+ u16 key_len;
+ u16 Kc_len;
+ u16 Ke_len;
+ u16 Ki_len;
+ u16 prf_len;
+ u16 block_len;
+ u16 conf_len;
+ u16 cksum_len;
+ ...
+ };
+
+The fields of interest to the user of the API are as follows:
+
+ * ``etype`` and ``ctype`` indicate the protocol number for this encoding
+ type for encryption and checksumming respectively. They hold
+ ``KRB5_ENCTYPE_*`` and ``KRB5_CKSUMTYPE_*`` constants.
+
+ * ``name`` is the formal name of the encoding.
+
+ * ``key_len`` and ``key_bytes`` are the input key length and the derived key
+ length. (I think they only differ for DES, which isn't supported here).
+
+ * ``Kc_len``, ``Ke_len`` and ``Ki_len`` are the sizes of the derived Kc, Ke
+ and Ki keys. Kc is used for in checksum mode; Ke and Ki are used in
+ encryption mode.
+
+ * ``prf_len`` is the size of the result from the PRF+ function calculation.
+
+ * ``block_len``, ``conf_len`` and ``cksum_len`` are the encryption block
+ length, confounder length and checksum length respectively. All three are
+ used in encryption mode, but only the checksum length is used in checksum
+ mode.
+
+The encoding type is looked up by number using the following function::
+
+ const struct krb5_enctype *crypto_krb5_find_enctype(u32 enctype);
+
+Key Derivation
+==============
+
+Once the application has selected an encryption type, the keys that will be
+used to do the actual crypto can be derived from the transport key.
+
+PRF+ Calculation
+----------------
+
+To aid in key derivation, a function to calculate the Kerberos GSSAPI
+mechanism's PRF+ is provided::
+
+ int crypto_krb5_calc_PRFplus(const struct krb5_enctype *krb5,
+ const struct krb5_buffer *K,
+ unsigned int L,
+ const struct krb5_buffer *S,
+ struct krb5_buffer *result,
+ gfp_t gfp);
+
+This can be used to derive the transport key from a source key plus additional
+data to limit its use.
+
+Crypto Functions
+================
+
+Once the keys have been derived, crypto can be performed on the data. The
+caller must leave gaps in the buffer for the storage of the confounder (if
+needed) and the checksum when preparing a message for transmission. An enum
+and a pair of functions are provided to aid in this::
+
+ enum krb5_crypto_mode {
+ KRB5_CHECKSUM_MODE,
+ KRB5_ENCRYPT_MODE,
+ };
+
+ size_t crypto_krb5_how_much_buffer(const struct krb5_enctype *krb5,
+ enum krb5_crypto_mode mode,
+ size_t data_size, size_t *_offset);
+
+ size_t crypto_krb5_how_much_data(const struct krb5_enctype *krb5,
+ enum krb5_crypto_mode mode,
+ size_t *_buffer_size, size_t *_offset);
+
+All these functions take the encoding type and an indication the mode of crypto
+(checksum-only or full encryption).
+
+The first function returns how big the buffer will need to be to house a given
+amount of data; the second function returns how much data will fit in a buffer
+of a particular size, and adjusts down the size of the required buffer
+accordingly. In both cases, the offset of the data within the buffer is also
+returned.
+
+When a message has been received, the location and size of the data with the
+message can be determined by calling::
+
+ void crypto_krb5_where_is_the_data(const struct krb5_enctype *krb5,
+ enum krb5_crypto_mode mode,
+ size_t *_offset, size_t *_len);
+
+The caller provides the offset and length of the message to the function, which
+then alters those values to indicate the region containing the data (plus any
+padding). It is up to the caller to determine how much padding there is.
+
+Preparation Functions
+---------------------
+
+Two functions are provided to allocated and prepare a crypto object for use by
+the action functions::
+
+ struct crypto_aead *
+ crypto_krb5_prepare_encryption(const struct krb5_enctype *krb5,
+ const struct krb5_buffer *TK,
+ u32 usage, gfp_t gfp);
+ struct crypto_shash *
+ crypto_krb5_prepare_checksum(const struct krb5_enctype *krb5,
+ const struct krb5_buffer *TK,
+ u32 usage, gfp_t gfp);
+
+Both of these functions take the encoding type, the transport key and the usage
+value used to derive the appropriate subkey(s). They create an appropriate
+crypto object, an AEAD template for encryption and a synchronous hash for
+checksumming, set the key(s) on it and configure it. The caller is expected to
+pass these handles to the action functions below.
+
+Encryption Mode
+---------------
+
+A pair of functions are provided to encrypt and decrypt a message::
+
+ ssize_t crypto_krb5_encrypt(const struct krb5_enctype *krb5,
+ struct crypto_aead *aead,
+ struct scatterlist *sg, unsigned int nr_sg,
+ size_t sg_len,
+ size_t data_offset, size_t data_len,
+ bool preconfounded);
+ int crypto_krb5_decrypt(const struct krb5_enctype *krb5,
+ struct crypto_aead *aead,
+ struct scatterlist *sg, unsigned int nr_sg,
+ size_t *_offset, size_t *_len);
+
+In both cases, the input and output buffers are indicated by the same
+scatterlist.
+
+For the encryption function, the output buffer may be larger than is needed
+(the amount of output generated is returned) and the location and size of the
+data are indicated (which must match the encoding). If no confounder is set,
+the function will insert one.
+
+For the decryption function, the offset and length of the message in buffer are
+supplied and these are shrunk to fit the data. The decryption function will
+verify any checksums within the message and give an error if they don't match.
+
+Checksum Mode
+-------------
+
+A pair of function are provided to generate the checksum on a message and to
+verify that checksum::
+
+ ssize_t crypto_krb5_get_mic(const struct krb5_enctype *krb5,
+ struct crypto_shash *shash,
+ const struct krb5_buffer *metadata,
+ struct scatterlist *sg, unsigned int nr_sg,
+ size_t sg_len,
+ size_t data_offset, size_t data_len);
+ int crypto_krb5_verify_mic(const struct krb5_enctype *krb5,
+ struct crypto_shash *shash,
+ const struct krb5_buffer *metadata,
+ struct scatterlist *sg, unsigned int nr_sg,
+ size_t *_offset, size_t *_len);
+
+In both cases, the input and output buffers are indicated by the same
+scatterlist. Additional metadata can be passed in which will get added to the
+hash before the data.
+
+For the get_mic function, the output buffer may be larger than is needed (the
+amount of output generated is returned) and the location and size of the data
+are indicated (which must match the encoding).
+
+For the verification function, the offset and length of the message in buffer
+are supplied and these are shrunk to fit the data. An error will be returned
+if the checksums don't match.
+
+The krb5enc AEAD algorithm
+==========================
+
+A template AEAD crypto algorithm, called "krb5enc", is provided that hashes the
+plaintext before encrypting it (the reverse of authenc). The handle returned
+by ``crypto_krb5_prepare_encryption()`` may be one of these, but there's no
+requirement for the user of this API to interact with it directly.
+
+For reference, its key format begins with a BE32 of the format number. Only
+format 1 is provided and that continues with a BE32 of the Ke key length
+followed by a BE32 of the Ki key length, followed by the bytes from the Ke key
+and then the Ki key.
+
+Using specifically ordered words means that the static test data doesn't
+require byteswapping.

+SHA-3 Algorithm Collection
+==========================
+
+.. contents::
+
+Overview
+========
+
+The SHA-3 family of algorithms, as specified in NIST FIPS-202 [1]_, contains six
+algorithms based on the Keccak sponge function. The differences between them
+are: the "rate" (how much of the state buffer gets updated with new data between
+invocations of the Keccak function and analogous to the "block size"), what
+domain separation suffix gets appended to the input data, and how much output
+data is extracted at the end. The Keccak sponge function is designed such that
+arbitrary amounts of output can be obtained for certain algorithms.
+
+Four digest algorithms are provided:
+
+ - SHA3-224
+ - SHA3-256
+ - SHA3-384
+ - SHA3-512
+
+Additionally, two Extendable-Output Functions (XOFs) are provided:
+
+ - SHAKE128
+ - SHAKE256
+
+The SHA-3 library API supports all six of these algorithms. The four digest
+algorithms are also supported by the crypto_shash and crypto_ahash APIs.
+
+This document describes the SHA-3 library API.
+
+
+Digests
+=======
+
+The following functions compute SHA-3 digests::
+
+ void sha3_224(const u8 *in, size_t in_len, u8 out[SHA3_224_DIGEST_SIZE]);
+ void sha3_256(const u8 *in, size_t in_len, u8 out[SHA3_256_DIGEST_SIZE]);
+ void sha3_384(const u8 *in, size_t in_len, u8 out[SHA3_384_DIGEST_SIZE]);
+ void sha3_512(const u8 *in, size_t in_len, u8 out[SHA3_512_DIGEST_SIZE]);
+
+For users that need to pass in data incrementally, an incremental API is also
+provided. The incremental API uses the following struct::
+
+ struct sha3_ctx { ... };
+
+Initialization is done with one of::
+
+ void sha3_224_init(struct sha3_ctx *ctx);
+ void sha3_256_init(struct sha3_ctx *ctx);
+ void sha3_384_init(struct sha3_ctx *ctx);
+ void sha3_512_init(struct sha3_ctx *ctx);
+
+Input data is then added with any number of calls to::
+
+ void sha3_update(struct sha3_ctx *ctx, const u8 *in, size_t in_len);
+
+Finally, the digest is generated using::
+
+ void sha3_final(struct sha3_ctx *ctx, u8 *out);
+
+which also zeroizes the context. The length of the digest is determined by the
+initialization function that was called.
+
+
+Extendable-Output Functions
+===========================
+
+The following functions compute the SHA-3 extendable-output functions (XOFs)::
+
+ void shake128(const u8 *in, size_t in_len, u8 *out, size_t out_len);
+ void shake256(const u8 *in, size_t in_len, u8 *out, size_t out_len);
+
+For users that need to provide the input data incrementally and/or receive the
+output data incrementally, an incremental API is also provided. The incremental
+API uses the following struct::
+
+ struct shake_ctx { ... };
+
+Initialization is done with one of::
+
+ void shake128_init(struct shake_ctx *ctx);
+ void shake256_init(struct shake_ctx *ctx);
+
+Input data is then added with any number of calls to::
+
+ void shake_update(struct shake_ctx *ctx, const u8 *in, size_t in_len);
+
+Finally, the output data is extracted with any number of calls to::
+
+ void shake_squeeze(struct shake_ctx *ctx, u8 *out, size_t out_len);
+
+and telling it how much data should be extracted. Note that performing multiple
+squeezes, with the output laid consecutively in a buffer, gets exactly the same
+output as doing a single squeeze for the combined amount over the same buffer.
+
+More input data cannot be added after squeezing has started.
+
+Once all the desired output has been extracted, zeroize the context::
+
+ void shake_zeroize_ctx(struct shake_ctx *ctx);
+
+
+Testing
+=======
+
+To test the SHA-3 code, use sha3_kunit (CONFIG_CRYPTO_LIB_SHA3_KUNIT_TEST).
+
+Since the SHA-3 algorithms are FIPS-approved, when the kernel is booted in FIPS
+mode the SHA-3 library also performs a simple self-test. This is purely to meet
+a FIPS requirement. Normal testing done by kernel developers and integrators
+should use the much more comprehensive KUnit test suite instead.

+===================================
+Using AutoFDO with the Linux kernel
+===================================
+
+This enables AutoFDO build support for the kernel when using
+the Clang compiler. AutoFDO (Auto-Feedback-Directed Optimization)
+is a type of profile-guided optimization (PGO) used to enhance the
+performance of binary executables. It gathers information about the
+frequency of execution of various code paths within a binary using
+hardware sampling. This data is then used to guide the compiler's
+optimization decisions, resulting in a more efficient binary. AutoFDO
+is a powerful optimization technique, and data indicates that it can
+significantly improve kernel performance. It's especially beneficial
+for workloads affected by front-end stalls.
+
+For AutoFDO builds, unlike non-FDO builds, the user must supply a
+profile. Acquiring an AutoFDO profile can be done in several ways.
+AutoFDO profiles are created by converting hardware sampling using
+the "perf" tool. It is crucial that the workload used to create these
+perf files is representative; they must exhibit runtime
+characteristics similar to the workloads that are intended to be
+optimized. Failure to do so will result in the compiler optimizing
+for the wrong objective.
+
+The AutoFDO profile often encapsulates the program's behavior. If the
+performance-critical codes are architecture-independent, the profile
+can be applied across platforms to achieve performance gains. For
+instance, using the profile generated on Intel architecture to build
+a kernel for AMD architecture can also yield performance improvements.
+
+There are two methods for acquiring a representative profile:
+(1) Sample real workloads using a production environment.
+(2) Generate the profile using a representative load test.
+When enabling the AutoFDO build configuration without providing an
+AutoFDO profile, the compiler only modifies the dwarf information in
+the kernel without impacting runtime performance. It's advisable to
+use a kernel binary built with the same AutoFDO configuration to
+collect the perf profile. While it's possible to use a kernel built
+with different options, it may result in inferior performance.
+
+One can collect profiles using AutoFDO build for the previous kernel.
+AutoFDO employs relative line numbers to match the profiles, offering
+some tolerance for source changes. This mode is commonly used in a
+production environment for profile collection.
+
+In a profile collection based on a load test, the AutoFDO collection
+process consists of the following steps:
+
+#. Initial build: The kernel is built with AutoFDO options
+ without a profile.
+
+#. Profiling: The above kernel is then run with a representative
+ workload to gather execution frequency data. This data is
+ collected using hardware sampling, via perf. AutoFDO is most
+ effective on platforms supporting advanced PMU features like
+ LBR on Intel machines.
+
+#. AutoFDO profile generation: Perf output file is converted to
+ the AutoFDO profile via offline tools.
+
+The support requires a Clang compiler LLVM 17 or later.
+
+Preparation
+===========
+
+Configure the kernel with::
+
+ CONFIG_AUTOFDO_CLANG=y
+
+Customization
+=============
+
+The default CONFIG_AUTOFDO_CLANG setting covers kernel space objects for
+AutoFDO builds. One can, however, enable or disable AutoFDO build for
+individual files and directories by adding a line similar to the following
+to the respective kernel Makefile:
+
+- For enabling a single file (e.g. foo.o) ::
+
+ AUTOFDO_PROFILE_foo.o := y
+
+- For enabling all files in one directory ::
+
+ AUTOFDO_PROFILE := y
+
+- For disabling one file ::
+
+ AUTOFDO_PROFILE_foo.o := n
+
+- For disabling all files in one directory ::
+
+ AUTOFDO_PROFILE := n
+
+Workflow
+========
+
+Here is an example workflow for AutoFDO kernel:
+
+1) Build the kernel on the host machine with LLVM enabled,
+ for example, ::
+
+ $ make menuconfig LLVM=1
+
+ Turn on AutoFDO build config::
+
+ CONFIG_AUTOFDO_CLANG=y
+
+ With a configuration that with LLVM enabled, use the following command::
+
+ $ scripts/config -e AUTOFDO_CLANG
+
+ After getting the config, build with ::
+
+ $ make LLVM=1
+
+2) Install the kernel on the test machine.
+
+3) Run the load tests. The '-c' option in perf specifies the sample
+ event period. We suggest using a suitable prime number, like 500009,
+ for this purpose.
+
+ - For Intel platforms::
+
+ $ perf record -e BR_INST_RETIRED.NEAR_TAKEN:k -a -N -b -c <count> -o <perf_file> -- <loadtest>
+
+ - For AMD platforms:
+
+ The supported systems are: Zen3 with BRS, or Zen4 with amd_lbr_v2. To check,
+
+ For Zen3::
+
+ $ cat /proc/cpuinfo | grep " brs"
+
+ For Zen4::
+
+ $ cat /proc/cpuinfo | grep amd_lbr_v2
+
+ The following command generated the perf data file::
+
+ $ perf record --pfm-events RETIRED_TAKEN_BRANCH_INSTRUCTIONS:k -a -N -b -c <count> -o <perf_file> -- <loadtest>
+
+4) (Optional) Download the raw perf file to the host machine.
+
+5) To generate an AutoFDO profile, two offline tools are available:
+ create_llvm_prof and llvm_profgen. The create_llvm_prof tool is part
+ of the AutoFDO project and can be found on GitHub
+ (https://github.com/google/autofdo), version v0.30.1 or later.
+ The llvm_profgen tool is included in the LLVM compiler itself. It's
+ important to note that the version of llvm_profgen doesn't need to match
+ the version of Clang. It needs to be the LLVM 19 release of Clang
+ or later, or just from the LLVM trunk. ::
+
+ $ llvm-profgen --kernel --binary=<vmlinux> --perfdata=<perf_file> -o <profile_file>
+
+ or ::
+
+ $ create_llvm_prof --binary=<vmlinux> --profile=<perf_file> --format=extbinary --out=<profile_file>
+
+ Note that multiple AutoFDO profile files can be merged into one via::
+
+ $ llvm-profdata merge -o <profile_file> <profile_1> <profile_2> ... <profile_n>
+
+6) Rebuild the kernel using the AutoFDO profile file with the same config as step 1,
+ (Note CONFIG_AUTOFDO_CLANG needs to be enabled)::
+
+ $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<profile_file>

+UAPI Checker
+============
+
+The UAPI checker (``scripts/check-uapi.sh``) is a shell script which
+checks UAPI header files for userspace backwards-compatibility across
+the git tree.
+
+Options
+=======
+
+This section will describe the options with which ``check-uapi.sh``
+can be run.
+
+Usage::
+
+ check-uapi.sh [-b BASE_REF] [-p PAST_REF] [-j N] [-l ERROR_LOG] [-i] [-q] [-v]
+
+Available options::
+
+ -b BASE_REF Base git reference to use for comparison. If unspecified or empty,
+ will use any dirty changes in tree to UAPI files. If there are no
+ dirty changes, HEAD will be used.
+ -p PAST_REF Compare BASE_REF to PAST_REF (e.g. -p v6.1). If unspecified or empty,
+ will use BASE_REF^1. Must be an ancestor of BASE_REF. Only headers
+ that exist on PAST_REF will be checked for compatibility.
+ -j JOBS Number of checks to run in parallel (default: number of CPU cores).
+ -l ERROR_LOG Write error log to file (default: no error log is generated).
+ -i Ignore ambiguous changes that may or may not break UAPI compatibility.
+ -q Quiet operation.
+ -v Verbose operation (print more information about each header being checked).
+
+Environmental args::
+
+ ABIDIFF Custom path to abidiff binary
+ CC C compiler (default is "gcc")
+ ARCH Target architecture of C compiler (default is host arch)
+
+Exit codes::
+
+ 0) Success
+ 1) ABI difference detected
+ 2) Prerequisite not met
+
+Examples

+
+This is a change to an arm64-specific UAPI header file. In this example, I'm

+
+With an x86 compiler, we can't check header files in ``arch/arm64``, so the

+
+If we want to check the header file, we'll have to use an arm64 compiler and

+------------------------------------
+
+You can use the ``-b`` and ``-p`` options to examine different chunks of your
+git tree. For example, to check all changed UAPI header files between tags
+v6.0 and v6.1, you'd run::
+
+ % ./scripts/check-uapi.sh -b v6.1 -p v6.0
+ Installing user-facing UAPI headers from v6.1... OK

+
+Note: Before v5.3, a header file needed by the script is not present,
+so the script is unable to check changes before then.
+
+You'll notice that the script detected many UAPI changes that are not
+backwards compatible. Knowing that kernel UAPIs are supposed to be stable
+forever, this is an alarming result. This brings us to the next section:
+caveats.
+
+Caveats
+=======
+
+The UAPI checker makes no assumptions about the author's intention, so some
+types of changes may be flagged even though they intentionally break UAPI.
+
+Removals For Refactoring or Deprecation
+---------------------------------------
+
+Sometimes drivers for very old hardware are removed, such as in this example::
+
+ % ./scripts/check-uapi.sh -b ba47652ba655
+ Installing user-facing UAPI headers from ba47652ba655... OK
+ Installing user-facing UAPI headers from ba47652ba655^1... OK
+ Checking changes to UAPI headers between ba47652ba655^1 and ba47652ba655...
+ ==== UAPI header include/linux/meye.h was removed between ba47652ba655^1 and ba47652ba655 ====
+
+ error - 1/910 UAPI headers compatible with x86 appear _not_ to be backwards compatible
+
+The script will always flag removals (even if they're intentional).
+
+Struct Expansions
+-----------------
+
+Depending on how a structure is handled in kernelspace, a change which
+expands a struct could be non-breaking.
+
+If a struct is used as the argument to an ioctl, then the kernel driver
+must be able to handle ioctl commands of any size. Beyond that, you need
+to be careful when copying data from the user. Say, for example, that
+``struct foo`` is changed like this::
+
+ struct foo {
+ __u64 a; /* added in version 1 */
+ + __u32 b; /* added in version 2 */
+ + __u32 c; /* added in version 2 */
+ }
+
+By default, the script will flag this kind of change for further review::
+
+ [C] 'struct foo' changed:
+ type size changed from 64 to 128 (in bits)
+ 2 data member insertions:
+ '__u32 b', at offset 64 (in bits)
+ '__u32 c', at offset 96 (in bits)
+
+However, it is possible that this change was made safely.
+
+If a userspace program was built with version 1, it will think
+``sizeof(struct foo)`` is 8. That size will be encoded in the
+ioctl value that gets sent to the kernel. If the kernel is built
+with version 2, it will think the ``sizeof(struct foo)`` is 16.
+
+The kernel can use the ``_IOC_SIZE`` macro to get the size encoded
+in the ioctl code that the user passed in and then use
+``copy_struct_from_user()`` to safely copy the value::
+
+ int handle_ioctl(unsigned long cmd, unsigned long arg)
+ {
+ switch _IOC_NR(cmd) {
+ 0x01: {
+ struct foo my_cmd; /* size 16 in the kernel */
+
+ ret = copy_struct_from_user(&my_cmd, arg, sizeof(struct foo), _IOC_SIZE(cmd));
+ ...
+
+``copy_struct_from_user`` will zero the struct in the kernel and then copy
+only the bytes passed in from the user (leaving new members zeroized).
+If the user passed in a larger struct, the extra members are ignored.
+
+If you know this situation is accounted for in the kernel code, you can
+pass ``-i`` to the script, and struct expansions like this will be ignored.
+
+Flex Array Migration
+--------------------
+
+While the script handles expansion into an existing flex array, it does
+still flag initial migration to flex arrays from 1-element fake flex
+arrays. For example::
+
+ struct foo {
+ __u32 x;
+ - __u32 flex[1]; /* fake flex */
+ + __u32 flex[]; /* real flex */
+ };
+
+This change would be flagged by the script::
+
+ [C] 'struct foo' changed:
+ type size changed from 64 to 32 (in bits)
+ 1 data member change:
+ type of '__u32 flex[1]' changed:
+ type name changed from '__u32[1]' to '__u32[]'
+ array type size changed from 32 to 'unknown'
+ array type subrange 1 changed length from 1 to 'unknown'
+
+At this time, there's no way to filter these types of changes, so be
+aware of this possible false positive.
+
+Summary
+-------
+
+While many types of false positives are filtered out by the script,
+it's possible there are some cases where the script flags a change
+which does not break UAPI. It's also possible a change which *does*
+break userspace would not be flagged by this script. While the script
+has been run on much of the kernel history, there could still be corner
+cases that are not accounted for.
+
+The intention is for this script to be used as a quick check for
+maintainers or automated tooling, not as the end-all authority on
+patch compatibility. It's best to remember: use your best judgment
+(and ideally a unit test in userspace) to make sure your UAPI changes
+are backwards-compatible!

-Debugging kernel and modules via gdb
-====================================
-
-The kernel debugger kgdb, hypervisors like QEMU or JTAG-based hardware
-interfaces allow to debug the Linux kernel and its modules during runtime
-using gdb. Gdb comes with a powerful scripting interface for python. The
-kernel provides a collection of helper scripts that can simplify typical
-kernel debugging steps. This is a short tutorial about how to enable and use
-them. It focuses on QEMU/KVM virtual machines as target, but the examples can
-be transferred to the other gdb stubs as well.
-
-
-Requirements
-------------
-
-- gdb 7.2+ (recommended: 7.4+) with python support enabled (typically true
- for distributions)
-
-
-Setup
------
-
-- Create a virtual Linux machine for QEMU/KVM (see www.linux-kvm.org and
- www.qemu.org for more details). For cross-development,
- https://landley.net/aboriginal/bin keeps a pool of machine images and
- toolchains that can be helpful to start from.
-
-- Build the kernel with CONFIG_GDB_SCRIPTS enabled, but leave
- CONFIG_DEBUG_INFO_REDUCED off. If your architecture supports
- CONFIG_FRAME_POINTER, keep it enabled.
-
-- Install that kernel on the guest, turn off KASLR if necessary by adding
- "nokaslr" to the kernel command line.
- Alternatively, QEMU allows to boot the kernel directly using -kernel,
- -append, -initrd command line switches. This is generally only useful if
- you do not depend on modules. See QEMU documentation for more details on
- this mode. In this case, you should build the kernel with
- CONFIG_RANDOMIZE_BASE disabled if the architecture supports KASLR.
-
-- Build the gdb scripts (required on kernels v5.1 and above)::
-
- make scripts_gdb
-
-- Enable the gdb stub of QEMU/KVM, either
-
- - at VM startup time by appending "-s" to the QEMU command line
-
- or
-
- - during runtime by issuing "gdbserver" from the QEMU monitor
- console
-
-- cd /path/to/linux-build
-
-- Start gdb: gdb vmlinux
-
- Note: Some distros may restrict auto-loading of gdb scripts to known safe
- directories. In case gdb reports to refuse loading vmlinux-gdb.py, add::
-
- add-auto-load-safe-path /path/to/linux-build
-
- to ~/.gdbinit. See gdb help for more details.
-
-- Attach to the booted guest::
-
- (gdb) target remote :1234
-
-
-Examples of using the Linux-provided gdb helpers
-------------------------------------------------
-
-- Load module (and main kernel) symbols::
-
- (gdb) lx-symbols
- loading vmlinux
- scanning for modules in /home/user/linux/build
- loading @0xffffffffa0020000: /home/user/linux/build/net/netfilter/xt_tcpudp.ko

+Linux Kernel GPIO based sloppy logic analyzer
+=============================================
+
+:Author: Wolfram Sang
+
+Introduction
+============
+
+This document briefly describes how to run the GPIO based in-kernel sloppy
+logic analyzer running on an isolated CPU.
+
+The sloppy logic analyzer will utilize a few GPIO lines in input mode on a
+system to rapidly sample these digital lines, which will, if the Nyquist
+criteria is met, result in a time series log with approximate waveforms as they
+appeared on these lines. One way to use it is to analyze external traffic
+connected to these GPIO lines with wires (i.e. digital probes), acting as a
+common logic analyzer.
+
+Another feature is to snoop on on-chip peripherals if the I/O cells of these
+peripherals can be used in GPIO input mode at the same time as they are being
+used as inputs or outputs for the peripheral. That means you could e.g. snoop
+I2C traffic without any wiring (if your hardware supports it). In the pin
+control subsystem such pin controllers are called "non-strict": a certain pin
+can be used with a certain peripheral and as a GPIO input line at the same
+time.
+
+Note that this is a last resort analyzer which can be affected by latencies,
+non-deterministic code paths and non-maskable interrupts. It is called 'sloppy'
+for a reason. However, for e.g. remote development, it may be useful to get a
+first view and aid further debugging.
+
+Setup
+=====
+
+Your kernel must have CONFIG_DEBUG_FS and CONFIG_CPUSETS enabled. Ideally, your
+runtime environment does not utilize cpusets otherwise, then isolation of a CPU
+core is easiest. If you do need cpusets, check that helper script for the
+sloppy logic analyzer does not interfere with your other settings.
+
+Tell the kernel which GPIOs are used as probes. For a Device Tree based system,
+you need to use the following bindings. Because these bindings are only for
+debugging, there is no official schema::
+
+ i2c-analyzer {
+ compatible = "gpio-sloppy-logic-analyzer";
+ probe-gpios = <&gpio6 21 GPIO_OPEN_DRAIN>, <&gpio6 4 GPIO_OPEN_DRAIN>;
+ probe-names = "SCL", "SDA";
+ };
+
+Note that you must provide a name for every GPIO specified. Currently a
+maximum of 8 probes are supported. 32 are likely possible but are not
+implemented yet.
+
+Usage
+=====
+
+The logic analyzer is configurable via files in debugfs. However, it is
+strongly recommended to not use them directly, but to use the script
+``tools/gpio/gpio-sloppy-logic-analyzer``. Besides checking parameters more
+extensively, it will isolate the CPU core so you will have the least
+disturbance while measuring.
+
+The script has a help option explaining the parameters. For the above DT
+snippet which analyzes an I2C bus at 400kHz on a Renesas Salvator-XS board, the
+following settings are used: The isolated CPU shall be CPU1 because it is a big
+core in a big.LITTLE setup. Because CPU1 is the default, we don't need a
+parameter. The bus speed is 400kHz. So, the sampling theorem says we need to
+sample at least at 800kHz. However, falling edges of both signals in an I2C
+start condition happen faster, so we need a higher sampling frequency, e.g.
+``-s 1500000`` for 1.5MHz. Also, we don't want to sample right away but wait
+for a start condition on an idle bus. So, we need to set a trigger to a falling
+edge on SDA while SCL stays high, i.e. ``-t 1H+2F``. Last is the duration, let
+us assume 15ms here which results in the parameter ``-d 15000``. So,
+altogether::
+
+ gpio-sloppy-logic-analyzer -s 1500000 -t 1H+2F -d 15000
+
+Note that the process will return you back to the prompt but a sub-process is
+still sampling in the background. Unless this has finished, you will not find a
+result file in the current or specified directory. For the above example, we
+will then need to trigger I2C communication::
+
+ i2cdetect -y -r <your bus number>
+
+Result is a .sr file to be consumed with PulseView or sigrok-cli from the free
+`sigrok`_ project. It is a zip file which also contains the binary sample data
+which may be consumed by other software. The filename is the logic analyzer
+instance name plus a since-epoch timestamp.

Remote coverage collection
--------------------------
-With KCOV_ENABLE coverage is collected only for syscalls that are issued
-from the current process. With KCOV_REMOTE_ENABLE it's possible to collect
-coverage for arbitrary parts of the kernel code, provided that those parts
-are annotated with kcov_remote_start()/kcov_remote_stop().
-
-This allows to collect coverage from two types of kernel background
-threads: the global ones, that are spawned during kernel boot in a limited
-number of instances (e.g. one USB hub_event() worker thread is spawned per
-USB HCD); and the local ones, that are spawned when a user interacts with
-some kernel interface (e.g. vhost workers); as well as from soft
-interrupts.
-
-To enable collecting coverage from a global background thread or from a
-softirq, a unique global handle must be assigned and passed to the
-corresponding kcov_remote_start() call. Then a userspace process can pass
-a list of such handles to the KCOV_REMOTE_ENABLE ioctl in the handles
-array field of the kcov_remote_arg struct. This will attach the used kcov
-device to the code sections, that are referenced by those handles.
-
-Since there might be many local background threads spawned from different
-userspace processes, we can't use a single global handle per annotation.
-Instead, the userspace process passes a non-zero handle through the
-common_handle field of the kcov_remote_arg struct. This common handle gets
-saved to the kcov_handle field in the current task_struct and needs to be
-passed to the newly spawned threads via custom annotations. Those threads
-should in turn be annotated with kcov_remote_start()/kcov_remote_stop().
-
-Internally kcov stores handles as u64 integers. The top byte of a handle
-is used to denote the id of a subsystem that this handle belongs to, and
-the lower 4 bytes are used to denote the id of a thread instance within
-that subsystem. A reserved value 0 is used as a subsystem id for common
-handles as they don't belong to a particular subsystem. The bytes 4-7 are
-currently reserved and must be zero. In the future the number of bytes
-used for the subsystem or handle ids might be increased.
-
-When a particular userspace process collects coverage via a common
-handle, kcov will collect coverage for each code section that is annotated
-to use the common handle obtained as kcov_handle from the current
-task_struct. However non common handles allow to collect coverage
-selectively from different subsystems.
+Besides collecting coverage data from handlers of syscalls issued from a
+userspace process, KCOV can also collect coverage for parts of the kernel
+executing in other contexts - so-called "remote" coverage.
+
+Using KCOV to collect remote coverage requires:
+
+1. Modifying kernel code to annotate the code section from where coverage
+ should be collected with ``kcov_remote_start`` and ``kcov_remote_stop``.
+
+2. Using ``KCOV_REMOTE_ENABLE`` instead of ``KCOV_ENABLE`` in the userspace
+ process that collects coverage.
+
+Both ``kcov_remote_start`` and ``kcov_remote_stop`` annotations and the
+``KCOV_REMOTE_ENABLE`` ioctl accept handles that identify particular coverage
+collection sections. The way a handle is used depends on the context where the
+matching code section executes.
+
+KCOV supports collecting remote coverage from the following contexts:
+
+1. Global kernel background tasks. These are the tasks that are spawned during
+ kernel boot in a limited number of instances (e.g. one USB ``hub_event``
+ worker is spawned per one USB HCD).
+
+2. Local kernel background tasks. These are spawned when a userspace process
+ interacts with some kernel interface and are usually killed when the process
+ exits (e.g. vhost workers).
+
+3. Soft interrupts.
+
+For #1 and #3, a unique global handle must be chosen and passed to the
+corresponding ``kcov_remote_start`` call. Then a userspace process must pass
+this handle to ``KCOV_REMOTE_ENABLE`` in the ``handles`` array field of the
+``kcov_remote_arg`` struct. This will attach the used KCOV device to the code
+section referenced by this handle. Multiple global handles identifying
+different code sections can be passed at once.
+
+For #2, the userspace process instead must pass a non-zero handle through the
+``common_handle`` field of the ``kcov_remote_arg`` struct. This common handle
+gets saved to the ``kcov_handle`` field in the current ``task_struct`` and
+needs to be passed to the newly spawned local tasks via custom kernel code
+modifications. Those tasks should in turn use the passed handle in their
+``kcov_remote_start`` and ``kcov_remote_stop`` annotations.
+
+KCOV follows a predefined format for both global and common handles. Each
+handle is a ``u64`` integer. Currently, only the one top and the lower 4 bytes
+are used. Bytes 4-7 are reserved and must be zero.
+
+For global handles, the top byte of the handle denotes the id of a subsystem
+this handle belongs to. For example, KCOV uses ``1`` as the USB subsystem id.
+The lower 4 bytes of a global handle denote the id of a task instance within
+that subsystem. For example, each ``hub_event`` worker uses the USB bus number
+as the task instance id.
+
+For common handles, a reserved value ``0`` is used as a subsystem id, as such
+handles don't belong to a particular subsystem. The lower 4 bytes of a common
+handle identify a collective instance of all local tasks spawned by the
+userspace process that passed a common handle to ``KCOV_REMOTE_ENABLE``.
+
+In practice, any value can be used for common handle instance id if coverage
+is only collected from a single userspace process on the system. However, if
+common handles are used by multiple processes, unique instance ids must be
+used for each process. One option is to use the process id as the common
+handle instance id.
+
+The following program demonstrates using KCOV to collect coverage from both
+local tasks spawned by the process and the global task that handles USB bus #1:

+configured a desired upper timeout for the test. Only a few tests override

+KUnit can be accessed from userspace via the debugfs filesystem (See more

+
+If ``CONFIG_KUNIT_DEBUGFS`` is enabled, the KUnit debugfs filesystem is
+mounted at /sys/kernel/debug/kunit. You can use this filesystem to perform
+the following actions.
+
+Retrieve Test Results
+=====================
+
+You can use debugfs to retrieve KUnit test results. The test results are
+accessible from the debugfs filesystem in the following read-only file:
+
+.. code-block :: bash
+
+ /sys/kernel/debug/kunit/<test_suite>/results
+
+The test results are printed in a KTAP document. Note this document is separate
+to the kernel log and thus, may have different test suite numbering.
+
+Run Tests After Kernel Has Booted
+=================================
+
+You can use the debugfs filesystem to trigger built-in tests to run after
+boot. To run the test suite, you can use the following command to write to
+the ``/sys/kernel/debug/kunit/<test_suite>/run`` file:
+
+.. code-block :: bash
+
+ echo "any string" > /sys/kernel/debugfs/kunit/<test_suite>/run
+
+As a result, the test suite runs and the results are printed to the kernel
+log.
+
+However, this feature is not available with KUnit suites that use init data,
+because init data may have been discarded after the kernel boots. KUnit
+suites that use init data should be defined using the
+kunit_test_init_section_suites() macro.
+
+Also, you cannot use this feature to run tests concurrently. Instead a test
+will wait to run until other tests have completed or failed.
+
.. note ::
- If ``CONFIG_KUNIT_DEBUGFS`` is enabled, KUnit test results will
- be accessible from the ``debugfs`` filesystem (if mounted).
- They will be in ``/sys/kernel/debug/kunit/<test_suite>/results``, in
- TAP format.
+ For test authors, to use this feature, tests will need to correctly initialise
+ and/or clean up any data, so the test runs correctly a second time.

+Test Attributes and Filtering
+=============================
+
+Test suites and cases can be marked with test attributes, such as speed of
+test. These attributes will later be printed in test output and can be used to
+filter test execution.
+
+Marking Test Attributes
+-----------------------
+
+Tests are marked with an attribute by including a ``kunit_attributes`` object
+in the test definition.
+
+Test cases can be marked using the ``KUNIT_CASE_ATTR(test_name, attributes)``
+macro to define the test case instead of ``KUNIT_CASE(test_name)``.
+
+.. code-block:: c
+
+ static const struct kunit_attributes example_attr = {
+ .speed = KUNIT_VERY_SLOW,
+ };
+
+ static struct kunit_case example_test_cases[] = {
+ KUNIT_CASE_ATTR(example_test, example_attr),
+ };
+
+.. note::
+ To mark a test case as slow, you can also use ``KUNIT_CASE_SLOW(test_name)``.
+ This is a helpful macro as the slow attribute is the most commonly used.
+
+Test suites can be marked with an attribute by setting the "attr" field in the
+suite definition.
+
+.. code-block:: c
+
+ static const struct kunit_attributes example_attr = {
+ .speed = KUNIT_VERY_SLOW,
+ };
+
+ static struct kunit_suite example_test_suite = {
+ ...,
+ .attr = example_attr,
+ };
+
+.. note::
+ Not all attributes need to be set in a ``kunit_attributes`` object. Unset
+ attributes will remain uninitialized and act as though the attribute is set
+ to 0 or NULL. Thus, if an attribute is set to 0, it is treated as unset.
+ These unset attributes will not be reported and may act as a default value
+ for filtering purposes.
+
+Reporting Attributes
+--------------------
+
+When a user runs tests, attributes will be present in the raw kernel output (in
+KTAP format). Note that attributes will be hidden by default in kunit.py output
+for all passing tests but the raw kernel output can be accessed using the
+``--raw_output`` flag. This is an example of how test attributes for test cases
+will be formatted in kernel output:
+
+.. code-block:: none
+
+ # example_test.speed: slow
+ ok 1 example_test
+
+This is an example of how test attributes for test suites will be formatted in
+kernel output:
+
+.. code-block:: none
+
+ KTAP version 2
+ # Subtest: example_suite
+ # module: kunit_example_test
+ 1..3
+ ...
+ ok 1 example_suite
+
+Additionally, users can output a full attribute report of tests with their
+attributes, using the command line flag ``--list_tests_attr``:
+
+.. code-block:: bash
+
+ kunit.py run "example" --list_tests_attr
+
+.. note::
+ This report can be accessed when running KUnit manually by passing in the
+ module_param ``kunit.action=list_attr``.
+
+Filtering
+---------
+
+Users can filter tests using the ``--filter`` command line flag when running
+tests. As an example:
+
+.. code-block:: bash
+
+ kunit.py run --filter speed=slow
+
+
+You can also use the following operations on filters: "<", ">", "<=", ">=",
+"!=", and "=". Example:
+
+.. code-block:: bash
+
+ kunit.py run --filter "speed>slow"
+
+This example will run all tests with speeds faster than slow. Note that the
+characters < and > are often interpreted by the shell, so they may need to be
+quoted or escaped, as above.
+
+Additionally, you can use multiple filters at once. Simply separate filters
+using commas. Example:
+
+.. code-block:: bash
+
+ kunit.py run --filter "speed>slow, module=kunit_example_test"
+
+.. note::
+ You can use this filtering feature when running KUnit manually by passing
+ the filter as a module param: ``kunit.filter="speed>slow, speed<=normal"``.
+
+Filtered tests will not run or show up in the test output. You can use the
+``--filter_action=skip`` flag to skip filtered tests instead. These tests will be
+shown in the test output in the test but will not run. To use this feature when
+running KUnit manually, use the module param ``kunit.filter_action=skip``.
+
+Rules of Filtering Procedure
+----------------------------
+
+Since both suites and test cases can have attributes, there may be conflicts
+between attributes during filtering. The process of filtering follows these
+rules:
+
+- Filtering always operates at a per-test level.
+
+- If a test has an attribute set, then the test's value is filtered on.
+
+- Otherwise, the value falls back to the suite's value.
+
+- If neither are set, the attribute has a global "default" value, which is used.
+
+List of Current Attributes
+--------------------------
+
+``speed``
+
+This attribute indicates the speed of a test's execution (how slow or fast the
+test is).
+
+This attribute is saved as an enum with the following categories: "normal",
+"slow", or "very_slow". The assumed default speed for tests is "normal". This
+indicates that the test takes a relatively trivial amount of time (less than
+1 second), regardless of the machine it is running on. Any test slower than
+this could be marked as "slow" or "very_slow".
+
+The macro ``KUNIT_CASE_SLOW(test_name)`` can be easily used to set the speed
+of a test case to "slow".
+
+``module``
+
+This attribute indicates the name of the module associated with the test.
+
+This attribute is automatically saved as a string and is printed for each suite.
+Tests can also be filtered using this attribute.
+
+``is_init``
+
+This attribute indicates whether the test uses init data or functions.
+
+This attribute is automatically saved as a boolean and tests can also be
+filtered using this attribute.

+KUnit tests are often compiled as a separate module. To avoid conflicting
+with regular modules, KUnit modules should be named after the test suite,

+Test source files, whether compiled as a separate module or an

Parameterized Testing
~~~~~~~~~~~~~~~~~~~~~
-The table-driven testing pattern is common enough that KUnit has special
-support for it.
+To run a test case against multiple inputs, KUnit provides a parameterized
+testing framework. This feature formalizes and extends the concept of
+table-driven tests discussed previously.
+
+A KUnit test is determined to be parameterized if a parameter generator function
+is provided when registering the test case. A test user can either write their
+own generator function or use one that is provided by KUnit. The generator
+function is stored in ``kunit_case->generate_params`` and can be set using the
+macros described in the section below.
+
+To establish the terminology, a "parameterized test" is a test which is run
+multiple times (once per "parameter" or "parameter run"). Each parameter run has
+both its own independent ``struct kunit`` (the "parameter run context") and
+access to a shared parent ``struct kunit`` (the "parameterized test context").

+Custom Parameter Generator Function:
+
+ The generator function is responsible for generating parameters one-by-one
+ and has the following signature:
+ ``const void* (*)(struct kunit *test, const void *prev, char *desc)``.
+ You can pass the generator function to the ``KUNIT_CASE_PARAM``
+ or ``KUNIT_CASE_PARAM_WITH_INIT`` macros.
+
+ The function receives the previously generated parameter as the ``prev`` argument
+ (which is ``NULL`` on the first call) and can also access the parameterized
+ test context passed as the ``test`` argument. KUnit calls this function

+ test ended.

+
+Runtime Parameter Array Registration in the Init Function:
+
+ For scenarios where you might need to initialize a parameterized test, you
+ can directly register a parameter array to the parameterized test context.
+
+ To do this, you must pass the parameterized test context, the array itself,
+ the array size, and a ``get_description()`` function to the
+ ``kunit_register_params_array()`` macro. This macro populates
+ ``struct kunit_params`` within the parameterized test context, effectively
+ storing a parameter array object. The ``get_description()`` function will
+ be used for populating parameter descriptions and has the following signature:
+ ``void (*)(struct kunit *test, const void *param, char *desc)``. Note that it
+ also has access to the parameterized test context.
+
+ .. important::
+ When using this way to register a parameter array, you will need to
+ manually pass ``kunit_array_gen_params()`` as the generator function to
+ ``KUNIT_CASE_PARAM_WITH_INIT``. ``kunit_array_gen_params()`` is a KUnit
+ helper that will use the registered array to generate the parameters.
+
+ If needed, instead of passing the KUnit helper, you can also pass your
+ own custom generator function that utilizes the parameter array. To
+ access the parameter array from within the parameter generator
+ function use ``test->params_array.params``.
+
+ The ``kunit_register_params_array()`` macro should be called within a
+ ``param_init()`` function that initializes the parameterized test and has
+ the following signature ``int (*)(struct kunit *test)``. For a detailed
+ explanation of this mechanism please refer to the "Adding Shared Resources"
+ section that is after this one. This method supports registering both
+ dynamically built and static parameter arrays.
+
+ The code snippet below shows the ``example_param_init_dynamic_arr`` test that
+ utilizes ``make_fibonacci_params()`` to create a dynamic array, which is then
+ registered using ``kunit_register_params_array()``. To see the full code

+
+Adding Shared Resources
+^^^^^^^^^^^^^^^^^^^^^^^
+All parameter runs in this framework hold a reference to the parameterized test
+context, which can be accessed using the parent ``struct kunit`` pointer. The
+parameterized test context is not used to execute any test logic itself; instead,
+it serves as a container for shared resources.
+
+It's possible to add resources to share between parameter runs within a
+parameterized test by using ``KUNIT_CASE_PARAM_WITH_INIT``, to which you pass
+custom ``param_init()`` and ``param_exit()`` functions. These functions run once
+before and once after the parameterized test, respectively.
+
+The ``param_init()`` function, with the signature ``int (*)(struct kunit *test)``,
+can be used for adding resources to the ``resources`` or ``priv`` fields of
+the parameterized test context, registering the parameter array, and any other
+initialization logic.
+
+The ``param_exit()`` function, with the signature ``void (*)(struct kunit *test)``,
+can be used to release any resources that were not parameterized test managed (i.e.
+not automatically cleaned up after the parameterized test ends) and for any other
+exit logic.
+
+Both ``param_init()`` and ``param_exit()`` are passed the parameterized test
+context behind the scenes. However, the test case function receives the parameter
+run context. Therefore, to manage and access shared resources from within a test
+case function, you must use ``test->parent``.
+
+For instance, finding a shared resource allocated by the Resource API requires
+passing ``test->parent`` to ``kunit_find_resource()``. This principle extends to
+all other APIs that might be used in the test case function, including
+``kunit_kzalloc()``, ``kunit_kmalloc_array()``, and others (see
+Documentation/dev-tools/kunit/api/test.rst and the
+Documentation/dev-tools/kunit/api/resource.rst).
+
+.. note::
+ The ``suite->init()`` function, which executes before each parameter run,
+ receives the parameter run context. Therefore, any resources set up in
+ ``suite->init()`` are cleaned up after each parameter run.
+
+The code below shows how you can add the shared resources. Note that this code
+utilizes the Resource API, which you can read more about here:

+
+As an alternative to using the KUnit Resource API for sharing resources, you can
+place them in ``test->parent->priv``. This serves as a more lightweight method
+for resource storage, best for scenarios where complex resource management is
+not required.
+
+As stated previously ``param_init()`` and ``param_exit()`` get the parameterized
+test context. So, you can directly use ``test->priv`` within ``param_init/exit``
+to manage shared resources. However, from within the test case function, you must
+navigate up to the parent ``struct kunit`` i.e. the parameterized test context.
+Therefore, you need to use ``test->parent->priv`` to access those same
+resources.
+
+The resources placed in ``test->parent->priv`` will need to be allocated in
+memory to persist across the parameter runs. If memory is allocated using the
+KUnit memory allocation APIs (described more in the "Allocating Memory" section
+below), you won't need to worry about deallocation. The APIs will make the memory
+parameterized test 'managed', ensuring that it will automatically get cleaned up
+after the parameterized test concludes.
+

+resources:

+Registering Cleanup Actions
+---------------------------
+
+If you need to perform some cleanup beyond simple use of ``kunit_kzalloc``,
+you can register a custom "deferred action", which is a cleanup function
+run when the test exits (whether cleanly, or via a failed assertion).
+
+Actions are simple functions with no return value, and a single ``void*``
+context argument, and fulfill the same role as "cleanup" functions in Python
+and Go tests, "defer" statements in languages which support them, and
+(in some cases) destructors in RAII languages.
+
+These are very useful for unregistering things from global lists, closing
+files or other resources, or freeing resources.
+
+For example:
+
+.. code-block:: C
+
+ static void cleanup_device(void *ctx)
+ {
+ struct device *dev = (struct device *)ctx;
+
+ device_unregister(dev);
+ }
+
+ void example_device_test(struct kunit *test)
+ {
+ struct my_device dev;
+
+ device_register(&dev);
+
+ kunit_add_action(test, &cleanup_device, &dev);
+ }
+
+Note that, for functions like device_unregister which only accept a single
+pointer-sized argument, it's possible to automatically generate a wrapper
+with the ``KUNIT_DEFINE_ACTION_WRAPPER()`` macro, for example:
+
+.. code-block:: C
+
+ KUNIT_DEFINE_ACTION_WRAPPER(device_unregister, device_unregister_wrapper, struct device *);
+ kunit_add_action(test, &device_unregister_wrapper, &dev);
+
+You should do this in preference to manually casting to the ``kunit_action_t`` type,
+as casting function pointers will break Control Flow Integrity (CFI).
+
+``kunit_add_action`` can fail if, for example, the system is out of memory.
+You can use ``kunit_add_action_or_reset`` instead which runs the action
+immediately if it cannot be deferred.
+
+If you need more control over when the cleanup function is called, you
+can trigger it early using ``kunit_release_action``, or cancel it entirely
+with ``kunit_remove_action``.
+
Testing Static Functions
------------------------
-If we do not want to expose functions or variables for testing, one option is to
-conditionally ``#include`` the test file at the end of your .c file. For
-example:
+If you want to test static functions without exposing those functions outside of
+testing, one option is conditionally export the symbol. When KUnit is enabled,
+the symbol is exposed but remains static otherwise. To use this method, follow
+the template below.
+
+.. code-block:: c
+
+ /* In the file containing functions to test "my_file.c" */
+
+ #include <kunit/visibility.h>
+ #include <my_file.h>
+ ...
+ VISIBLE_IF_KUNIT int do_interesting_thing()
+ {
+ ...
+ }
+ EXPORT_SYMBOL_IF_KUNIT(do_interesting_thing);
+
+ /* In the header file "my_file.h" */
+
+ #if IS_ENABLED(CONFIG_KUNIT)
+ int do_interesting_thing(void);
+ #endif
+
+ /* In the KUnit test file "my_file_test.c" */
+
+ #include <kunit/visibility.h>
+ #include <my_file.h>
+ ...
+ MODULE_IMPORT_NS("EXPORTED_FOR_KUNIT_TESTING");
+ ...
+ // Use do_interesting_thing() in tests
+
+For a full example, see this `patch <https://lore.kernel.org/all/20221207014024.340230-3-rmoar@google.com/>`_
+where a test is modified to conditionally expose static functions for testing
+using the macros above.
+
+As an **alternative** to the method above, you could conditionally ``#include``
+the test file at the end of your .c file. This is not recommended but works
+if needed. For example:
.. code-block:: c
- /* In my_file.c */
+ /* In "my_file.c" */
static int do_interesting_thing();

KUnit is not enabled, or if no test is running in the current task, it will do
nothing. This compiles down to either a no-op or a static key check, so will
have a negligible performance impact when no test is running.
+
+Managing Fake Devices and Drivers
+---------------------------------
+
+When testing drivers or code which interacts with drivers, many functions will
+require a ``struct device`` or ``struct device_driver``. In many cases, setting
+up a real device is not required to test any given function, so a fake device
+can be used instead.
+
+KUnit provides helper functions to create and manage these fake devices, which
+are internally of type ``struct kunit_device``, and are attached to a special
+``kunit_bus``. These devices support managed device resources (devres), as
+described in Documentation/driver-api/driver-model/devres.rst
+
+To create a KUnit-managed ``struct device_driver``, use ``kunit_driver_create()``,
+which will create a driver with the given name, on the ``kunit_bus``. This driver
+will automatically be destroyed when the corresponding test finishes, but can also
+be manually destroyed with ``driver_unregister()``.
+
+To create a fake device, use the ``kunit_device_register()``, which will create
+and register a device, using a new KUnit-managed driver created with ``kunit_driver_create()``.
+To provide a specific, non-KUnit-managed driver, use ``kunit_device_register_with_driver()``
+instead. Like with managed drivers, KUnit-managed fake devices are automatically
+cleaned up when the test finishes, but can be manually cleaned up early with
+``kunit_device_unregister()``.
+
+The KUnit devices should be used in preference to ``root_device_register()``, and
+instead of ``platform_device_register()`` in cases where the device is not otherwise
+a platform device.
+
+For example:
+
+.. code-block:: c
+
+ #include <kunit/device.h>
+
+ static void test_my_device(struct kunit *test)
+ {
+ struct device *fake_device;
+ const char *dev_managed_string;
+
+ // Create a fake device.
+ fake_device = kunit_device_register(test, "my_device");
+ KUNIT_ASSERT_NOT_ERR_OR_NULL(test, fake_device)
+
+ // Pass it to functions which need a device.
+ dev_managed_string = devm_kstrdup(fake_device, "Hello, World!");
+
+ // Everything is cleaned up automatically when the test ends.

+=====================================
+Using Propeller with the Linux kernel
+=====================================
+
+This enables Propeller build support for the kernel when using Clang
+compiler. Propeller is a profile-guided optimization (PGO) method used
+to optimize binary executables. Like AutoFDO, it utilizes hardware
+sampling to gather information about the frequency of execution of
+different code paths within a binary. Unlike AutoFDO, this information
+is then used right before linking phase to optimize (among others)
+block layout within and across functions.
+
+A few important notes about adopting Propeller optimization:
+
+#. Although it can be used as a standalone optimization step, it is
+ strongly recommended to apply Propeller on top of AutoFDO,
+ AutoFDO+ThinLTO or Instrument FDO. The rest of this document
+ assumes this paradigm.
+
+#. Propeller uses another round of profiling on top of
+ AutoFDO/AutoFDO+ThinLTO/iFDO. The whole build process involves
+ "build-afdo - train-afdo - build-propeller - train-propeller -
+ build-optimized".
+
+#. Propeller requires LLVM 19 release or later for Clang/Clang++
+ and the linker(ld.lld).
+
+#. In addition to LLVM toolchain, Propeller requires a profiling
+ conversion tool: https://github.com/google/autofdo with a release
+ after v0.30.1: https://github.com/google/autofdo/releases/tag/v0.30.1.
+
+The Propeller optimization process involves the following steps:
+
+#. Initial building: Build the AutoFDO or AutoFDO+ThinLTO binary as
+ you would normally do, but with a set of compile-time / link-time
+ flags, so that a special metadata section is created within the
+ kernel binary. The special section is only intend to be used by the
+ profiling tool, it is not part of the runtime image, nor does it
+ change kernel run time text sections.
+
+#. Profiling: The above kernel is then run with a representative
+ workload to gather execution frequency data. This data is collected
+ using hardware sampling, via perf. Propeller is most effective on
+ platforms supporting advanced PMU features like LBR on Intel
+ machines. This step is the same as profiling the kernel for AutoFDO
+ (the exact perf parameters can be different).
+
+#. Propeller profile generation: Perf output file is converted to a
+ pair of Propeller profiles via an offline tool.
+
+#. Optimized build: Build the AutoFDO or AutoFDO+ThinLTO optimized
+ binary as you would normally do, but with a compile-time /
+ link-time flag to pick up the Propeller compile time and link time
+ profiles. This build step uses 3 profiles - the AutoFDO profile,
+ the Propeller compile-time profile and the Propeller link-time
+ profile.
+
+#. Deployment: The optimized kernel binary is deployed and used
+ in production environments, providing improved performance
+ and reduced latency.
+
+Preparation
+===========
+
+Configure the kernel with::
+
+ CONFIG_AUTOFDO_CLANG=y
+ CONFIG_PROPELLER_CLANG=y
+
+Customization
+=============
+
+The default CONFIG_PROPELLER_CLANG setting covers kernel space objects
+for Propeller builds. One can, however, enable or disable Propeller build
+for individual files and directories by adding a line similar to the
+following to the respective kernel Makefile:
+
+- For enabling a single file (e.g. foo.o)::
+
+ PROPELLER_PROFILE_foo.o := y
+
+- For enabling all files in one directory::
+
+ PROPELLER_PROFILE := y
+
+- For disabling one file::
+
+ PROPELLER_PROFILE_foo.o := n
+
+- For disabling all files in one directory::
+
+ PROPELLER__PROFILE := n
+
+
+Workflow
+========
+
+Here is an example workflow for building an AutoFDO+Propeller kernel:
+
+1) Assuming an AutoFDO profile is already collected following
+ instructions in the AutoFDO document, build the kernel on the host
+ machine, with AutoFDO and Propeller build configs ::
+
+ CONFIG_AUTOFDO_CLANG=y
+ CONFIG_PROPELLER_CLANG=y
+
+ and ::
+
+ $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<autofdo-profile-name>
+
+2) Install the kernel on the test machine.
+
+3) Run the load tests. The '-c' option in perf specifies the sample
+ event period. We suggest using a suitable prime number, like 500009,
+ for this purpose.
+
+ - For Intel platforms::
+
+ $ perf record -e BR_INST_RETIRED.NEAR_TAKEN:k -a -N -b -c <count> -o <perf_file> -- <loadtest>
+
+ - For AMD platforms::
+
+ $ perf record --pfm-event RETIRED_TAKEN_BRANCH_INSTRUCTIONS:k -a -N -b -c <count> -o <perf_file> -- <loadtest>
+
+ Note you can repeat the above steps to collect multiple <perf_file>s.
+
+4) (Optional) Download the raw perf file(s) to the host machine.
+
+5) Use the create_llvm_prof tool (https://github.com/google/autofdo) to
+ generate Propeller profile. ::
+
+ $ create_llvm_prof --binary=<vmlinux> --profile=<perf_file>
+ --format=propeller --propeller_output_module_name
+ --out=<propeller_profile_prefix>_cc_profile.txt
+ --propeller_symorder=<propeller_profile_prefix>_ld_profile.txt
+
+ "<propeller_profile_prefix>" can be something like "/home/user/dir/any_string".
+
+ This command generates a pair of Propeller profiles:
+ "<propeller_profile_prefix>_cc_profile.txt" and
+ "<propeller_profile_prefix>_ld_profile.txt".
+
+ If there are more than 1 perf_file collected in the previous step,
+ you can create a temp list file "<perf_file_list>" with each line
+ containing one perf file name and run::
+
+ $ create_llvm_prof --binary=<vmlinux> --profile=@<perf_file_list>
+ --format=propeller --propeller_output_module_name
+ --out=<propeller_profile_prefix>_cc_profile.txt
+ --propeller_symorder=<propeller_profile_prefix>_ld_profile.txt
+
+6) Rebuild the kernel using the AutoFDO and Propeller
+ profiles. ::
+
+ CONFIG_AUTOFDO_CLANG=y
+ CONFIG_PROPELLER_CLANG=y
+
+ and ::
+
+ $ make LLVM=1 CLANG_AUTOFDO_PROFILE=<profile_file> CLANG_PROPELLER_PROFILE_PREFIX=<propeller_profile_prefix>

+Device testing with kselftest
+=============================
+
+
+There are a few different kselftests available for testing devices generically,
+with some overlap in coverage and different requirements. This document aims to
+give an overview of each one.
+
+Note: Paths in this document are relative to the kselftest folder
+(``tools/testing/selftests``).
+
+Device oriented kselftests:
+
+* Devicetree (``dt``)
+
+ * **Coverage**: Probe status for devices described in Devicetree
+ * **Requirements**: None
+
+* Error logs (``devices/error_logs``)
+
+ * **Coverage**: Error (or more critical) log messages presence coming from any
+ device
+ * **Requirements**: None
+
+* Discoverable bus (``devices/probe``)
+
+ * **Coverage**: Presence and probe status of USB or PCI devices that have been
+ described in the reference file
+ * **Requirements**: Manually describe the devices that should be tested in a
+ YAML reference file (see ``devices/probe/boards/google,spherion.yaml`` for
+ an example)
+
+* Exist (``devices/exist``)
+
+ * **Coverage**: Presence of all devices
+ * **Requirements**: Generate the reference (see ``devices/exist/README.rst``
+ for details) on a known-good kernel
+
+Therefore, the suggestion is to enable the error log and devicetree tests on all
+(DT-based) platforms, since they don't have any requirements. Then to greatly
+improve coverage, generate the reference for each platform and enable the exist
+test. The discoverable bus test can be used to verify the probe status of
+specific USB or PCI devices, but is probably not worth it for most cases.

+description: |+
+ Common access controllers properties
+
+ Access controllers are in charge of stating which of the hardware blocks under
+ their responsibility (their domain) can be accesssed by which compartment. A
+ compartment can be a cluster of CPUs (or coprocessors), a range of addresses
+ or a group of hardware blocks. An access controller's domain is the set of
+ resources covered by the access controller.
+
+ This device tree binding can be used to bind devices to their access
+ controller provided by access-controllers property. In this case, the device
+ is a consumer and the access controller is the provider.
+
+ An access controller can be represented by any node in the device tree and
+ can provide one or more configuration parameters, needed to control parameters
+ of the consumer device. A consumer node can refer to the provider by phandle
+ and a set of phandle arguments, specified by '#access-controller-cells'
+ property in the access controller node.
+
+ Access controllers are typically used to set/read the permissions of a
+ hardware block and grant access to it. Any of which depends on the access
+ controller. The capabilities of each access controller are defined by the
+ binding of the access controller device.
+
+ Each node can be a consumer for the several access controllers.

+
+ The Coresight dummy sink component is for the specific coresight sink devices

+ debug and trace capabilities. For this device, a dummy driver is needed to

+ created in the driver. Then the trace flow would be transferred to EUD via
+ coresight link of AP processor. It provides Coresight API for operations on
+ dummy source devices, such as enabling and disabling them. It also provides
+ the Coresight dummy source paths for debugging.
+
+ The primary use case of the coresight dummy sink is to build path in kernel

-Freescale Vybrid Miscellaneous System Control - Interrupt Router
-
-The MSCM IP contains multiple sub modules, this binding describes the second
-block of registers which control the interrupt router. The interrupt router
-allows to configure the recipient of each peripheral interrupt. Furthermore
-it controls the directed processor interrupts. The module is available in all
-Vybrid SoC's but is only really useful in dual core configurations (VF6xx
-which comes with a Cortex-A5/Cortex-M4 combination).
-
-Required properties:
-- compatible: "fsl,vf610-mscm-ir"
-- reg: the register range of the MSCM Interrupt Router
-- fsl,cpucfg: The handle to the MSCM CPU configuration node, required
- to get the current CPU ID
-- interrupt-controller: Identifies the node as an interrupt controller
-- #interrupt-cells: Two cells, interrupt number and cells.
- The hardware interrupt number according to interrupt
- assignment of the interrupt router is required.
- Flags get passed only when using GIC as parent. Flags
- encoding as documented by the GIC bindings.
-
-Example:
- mscm_ir: interrupt-controller@40001800 {
- compatible = "fsl,vf610-mscm-ir";
- reg = <0x40001800 0x400>;
- fsl,cpucfg = <&mscm_cpucfg>;
- interrupt-controller;
- #interrupt-cells = <2>;
- interrupt-parent = <&intc>;
- }

+
+ Currently upstream this is devices using "gs101" SoC which is found in Pixel
+ 6, Pixel 6 Pro and Pixel 6a.
+
+ Google have a few different names for the SoC:
+ - Marketing name ("Tensor")
+ - Codename ("Whitechapel")
+ - SoC ID ("gs101")
+ - Die ID ("S5P9845")
+
+ Likewise there are a couple of names for the actual device
+ - Marketing name ("Pixel 6")
+ - Codename ("Oriole")
+
+ Devicetrees should use the lowercased SoC ID and lowercased board codename,
+ e.g. gs101 and gs101-oriole.

-SYSTEM CONTROLLER 1
-===================
-
-Thermal:
---------
-
-For common binding part and usage, refer to
-Documentation/devicetree/bindings/thermal/thermal*.yaml
-
-The thermal IP can probe the temperature all around the processor. It
-may feature several channels, each of them wired to one sensor.
-
-It is possible to setup an overheat interrupt by giving at least one
-critical point to any subnode of the thermal-zone node.
-
-Required properties:
-- compatible: must be one of:
- * marvell,armada-ap806-thermal
-- reg: register range associated with the thermal functions.
-
-Optional properties:
-- interrupts: overheat interrupt handle. Should point to line 18 of the
- SEI irqchip. See interrupt-controller/interrupts.txt
-- #thermal-sensor-cells: shall be <1> when thermal-zones subnodes refer
- to this IP and represents the channel ID. There is one sensor per
- channel. O refers to the thermal IP internal channel, while positive
- IDs refer to each CPU.
-
-Example:
-ap_syscon1: system-controller@6f8000 {
- compatible = "syscon", "simple-mfd";
- reg = <0x6f8000 0x1000>;
-
- ap_thermal: thermal-sensor@80 {
- compatible = "marvell,armada-ap806-thermal";
- reg = <0x80 0x10>;

-Marvell Armada CP110 System Controller
-======================================
-
-The CP110 is one of the two core HW blocks of the Marvell Armada 7K/8K
-SoCs. It contains system controllers, which provide several registers
-giving access to numerous features: clocks, pin-muxing and many other
-SoC configuration items. This DT binding allows to describe these
-system controllers.
-
-For the top level node:
- - compatible: must be: "syscon", "simple-mfd";
- - reg: register area of the CP110 system controller
-
-SYSTEM CONTROLLER 0
-===================
-
-Clocks:
--------
-
-The Device Tree node representing this System Controller 0 provides a
-number of clocks:
-
- - a set of core clocks
- - a set of gatable clocks
-
-Those clocks can be referenced by other Device Tree nodes using two
-cells:
- - The first cell must be 0 or 1. 0 for the core clocks and 1 for the
- gatable clocks.
- - The second cell identifies the particular core clock or gatable
- clocks.
-
-The following clocks are available:
- - Core clocks
- - 0 0 APLL
- - 0 1 PPv2 core
- - 0 2 EIP
- - 0 3 Core
- - 0 4 NAND core
- - 0 5 SDIO core
- - Gatable clocks
- - 1 0 Audio
- - 1 1 Comm Unit
- - 1 2 NAND
- - 1 3 PPv2
- - 1 4 SDIO
- - 1 5 MG Domain
- - 1 6 MG Core
- - 1 7 XOR1
- - 1 8 XOR0
- - 1 9 GOP DP
- - 1 11 PCIe x1 0
- - 1 12 PCIe x1 1
- - 1 13 PCIe x4
- - 1 14 PCIe / XOR
- - 1 15 SATA
- - 1 16 SATA USB
- - 1 17 Main
- - 1 18 SD/MMC/GOP
- - 1 21 Slow IO (SPI, NOR, BootROM, I2C, UART)
- - 1 22 USB3H0
- - 1 23 USB3H1
- - 1 24 USB3 Device
- - 1 25 EIP150
- - 1 26 EIP197
-
-Required properties:
-
- - compatible: must be:
- "marvell,cp110-clock"
- - #clock-cells: must be set to 2
-
-Pinctrl:
---------
-
-For common binding part and usage, refer to the file
-Documentation/devicetree/bindings/pinctrl/marvell,mvebu-pinctrl.txt.
-
-Required properties:
-
-- compatible: "marvell,armada-7k-pinctrl", "marvell,armada-8k-cpm-pinctrl",
- "marvell,armada-8k-cps-pinctrl" or "marvell,cp115-standalone-pinctrl"
- depending on the specific variant of the SoC being used.

-GPIO:
------
-
-For common binding part and usage, refer to
-Documentation/devicetree/bindings/gpio/gpio-mvebu.yaml.
-
-Required properties:
-
-- compatible: "marvell,armada-8k-gpio"
-
-- offset: offset address inside the syscon block
-
-Example:
-
-CP110_LABEL(syscon0): system-controller@440000 {
- compatible = "syscon", "simple-mfd";
- reg = <0x440000 0x1000>;
-
- CP110_LABEL(clk): clock {
- compatible = "marvell,cp110-clock";
- #clock-cells = <2>;
- };
-
- CP110_LABEL(pinctrl): pinctrl {
- compatible = "marvell,armada-8k-cpm-pinctrl";

-SYSTEM CONTROLLER 1
-===================
-
-Thermal:
---------
-
-The thermal IP can probe the temperature all around the processor. It
-may feature several channels, each of them wired to one sensor.
-
-It is possible to setup an overheat interrupt by giving at least one
-critical point to any subnode of the thermal-zone node.
-
-For common binding part and usage, refer to
-Documentation/devicetree/bindings/thermal/thermal*.yaml
-
-Required properties:
-- compatible: must be one of:
- * marvell,armada-cp110-thermal
-- reg: register range associated with the thermal functions.
-
-Optional properties:
-- interrupts-extended: overheat interrupt handle. Should point to
- a line of the ICU-SEI irqchip (116 is what is usually used by the
- firmware). The ICU-SEI will redirect towards interrupt line #37 of the
- AP SEI which is shared across all CPs.
- See interrupt-controller/interrupts.txt
-- #thermal-sensor-cells: shall be <1> when thermal-zones subnodes refer
- to this IP and represents the channel ID. There is one sensor per
- channel. O refers to the thermal IP internal channel.
-
-Example:
-CP110_LABEL(syscon1): system-controller@6f8000 {
- compatible = "syscon", "simple-mfd";
- reg = <0x6f8000 0x1000>;
-
- CP110_LABEL(thermal): thermal-sensor@70 {
- compatible = "marvell,armada-cp110-thermal";
- reg = <0x70 0x10>;
- interrupts-extended = <&CP110_LABEL(icu_sei) 116 IRQ_TYPE_LEVEL_HIGH>;
- #thermal-sensor-cells = <1>;
- };
-};

-MediaTek AUDSYS controller
-============================
-
-The MediaTek AUDSYS controller provides various clocks to the system.
-
-Required Properties:
-
-- compatible: Should be one of:
- - "mediatek,mt2701-audsys", "syscon"
- - "mediatek,mt6765-audsys", "syscon"
- - "mediatek,mt6779-audio", "syscon"
- - "mediatek,mt7622-audsys", "syscon"
- - "mediatek,mt7623-audsys", "mediatek,mt2701-audsys", "syscon"
- - "mediatek,mt8167-audiosys", "syscon"
- - "mediatek,mt8183-audiosys", "syscon"
- - "mediatek,mt8192-audsys", "syscon"
- - "mediatek,mt8516-audsys", "syscon"
-- #clock-cells: Must be 1
-
-The AUDSYS controller uses the common clk binding from
-Documentation/devicetree/bindings/clock/clock-bindings.txt
-The available clocks are defined in dt-bindings/clock/mt*-clk.h.
-
-Required sub-nodes:
--------
-For common binding part and usage, refer to
-../sonud/mt2701-afe-pcm.txt.
-
-Example:
-
- audsys: clock-controller@11220000 {
- compatible = "mediatek,mt7622-audsys", "syscon";
- reg = <0 0x11220000 0 0x2000>;
- #clock-cells = <1>;
-
- afe: audio-controller {

-QCOM Idle States for cpuidle driver
-
-ARM provides idle-state node to define the cpuidle states, as defined in [1].
-cpuidle-qcom is the cpuidle driver for Qualcomm SoCs and uses these idle
-states. Idle states have different enter/exit latency and residency values.
-The idle states supported by the QCOM SoC are defined as -
-
- * Standby
- * Retention
- * Standalone Power Collapse (Standalone PC or SPC)
- * Power Collapse (PC)
-
-Standby: Standby does a little more in addition to architectural clock gating.
-When the WFI instruction is executed the ARM core would gate its internal
-clocks. In addition to gating the clocks, QCOM cpus use this instruction as a
-trigger to execute the SPM state machine. The SPM state machine waits for the
-interrupt to trigger the core back in to active. This triggers the cache
-hierarchy to enter standby states, when all cpus are idle. An interrupt brings
-the SPM state machine out of its wait, the next step is to ensure that the
-cache hierarchy is also out of standby, and then the cpu is allowed to resume
-execution. This state is defined as a generic ARM WFI state by the ARM cpuidle
-driver and is not defined in the DT. The SPM state machine should be
-configured to execute this state by default and after executing every other
-state below.
-
-Retention: Retention is a low power state where the core is clock gated and
-the memory and the registers associated with the core are retained. The
-voltage may be reduced to the minimum value needed to keep the processor
-registers active. The SPM should be configured to execute the retention
-sequence and would wait for interrupt, before restoring the cpu to execution
-state. Retention may have a slightly higher latency than Standby.
-
-Standalone PC: A cpu can power down and warmboot if there is a sufficient time
-between the time it enters idle and the next known wake up. SPC mode is used
-to indicate a core entering a power down state without consulting any other
-cpu or the system resources. This helps save power only on that core. The SPM
-sequence for this idle state is programmed to power down the supply to the
-core, wait for the interrupt, restore power to the core, and ensure the
-system state including cache hierarchy is ready before allowing core to
-resume. Applying power and resetting the core causes the core to warmboot
-back into Elevation Level (EL) which trampolines the control back to the
-kernel. Entering a power down state for the cpu, needs to be done by trapping
-into a EL. Failing to do so, would result in a crash enforced by the warm boot
-code in the EL for the SoC. On SoCs with write-back L1 cache, the cache has to
-be flushed in s/w, before powering down the core.
-
-Power Collapse: This state is similar to the SPC mode, but distinguishes
-itself in that the cpu acknowledges and permits the SoC to enter deeper sleep
-modes. In a hierarchical power domain SoC, this means L2 and other caches can
-be flushed, system bus, clocks - lowered, and SoC main XO clock gated and
-voltages reduced, provided all cpus enter this state. Since the span of low
-power modes possible at this state is vast, the exit latency and the residency
-of this low power mode would be considered high even though at a cpu level,
-this essentially is cpu power down. The SPM in this state also may handshake
-with the Resource power manager (RPM) processor in the SoC to indicate a
-complete application processor subsystem shut down.
-
-The idle-state for QCOM SoCs are distinguished by the compatible property of
-the idle-states device node.
-
-The devicetree representation of the idle state should be -

- which are assigned to clients. Clients can query the slice details, activate
- and deactivate them.

-SPM AVS Wrapper 2 (SAW2)
-
-The SAW2 is a wrapper around the Subsystem Power Manager (SPM) and the
-Adaptive Voltage Scaling (AVS) hardware. The SPM is a programmable
-power-controller that transitions a piece of hardware (like a processor or
-subsystem) into and out of low power modes via a direct connection to
-the PMIC. It can also be wired up to interact with other processors in the
-system, notifying them when a low power state is entered or exited.
-
-Multiple revisions of the SAW hardware are supported using these Device Nodes.
-SAW2 revisions differ in the register offset and configuration data. Also, the
-same revision of the SAW in different SoCs may have different configuration
-data due the differences in hardware capabilities. Hence the SoC name, the
-version of the SAW hardware in that SoC and the distinction between cpu (big
-or Little) or cache, may be needed to uniquely identify the SAW register
-configuration and initialization data. The compatible string is used to
-indicate this parameter.

-* Qualcomm SSBI
-
-Some Qualcomm MSM devices contain a point-to-point serial bus used to
-communicate with a limited range of devices (mostly power management
-chips).
-
-These require the following properties:
-
-- compatible: "qcom,ssbi"
-
-- qcom,controller-type
- indicates the SSBI bus variant the controller should use to talk
- with the slave device. This should be one of "ssbi", "ssbi2", or
- "pmic-arbiter". The type chosen is determined by the attached
- slave.
-
-The slave device should be the single child node of the ssbi device
-with a compatible field.

+ The Trace Memory Controller(TMC) is used for Embedded Trace Buffer(ETB),
+ Embedded Trace FIFO(ETF) and Embedded Trace Router(ETR) configurations.
+ The configuration mode (ETB, ETF, ETR) is discovered at boot time when
+ the device is probed.
+
+ The Coresight TMC Control unit controls various Coresight behaviors.
+ It works as a helper device when connected to TMC ETR device.
+ It is responsible for controlling the data filter function based on
+ the source device's Trace ID for TMC ETR device. The trace data with
+ that Trace id can get into ETR's buffer while other trace data gets
+ ignored.

+description: >
+ The Trace Network On Chip (TNOC) is an integration hierarchy hardware
+ component that integrates the functionalities of TPDA and funnels.
+
+ It sits in the different subsystem of SOC and aggregates the trace and
+ transports it to Aggregation TNOC or to coresight trace sink eventually.
+ TNOC embeds bridges for all the interfaces APB, ATB, TPDA and NTS (Narrow
+ Time Stamp).
+
+ TNOC can take inputs from different trace sources i.e. ATB, TPDM.
+
+ Note this binding is specifically intended for Aggregator TNOC instances.

-Synaptics SoC Device Tree Bindings
-
-According to https://www.synaptics.com/company/news/conexant-marvell
-Synaptics has acquired the Multimedia Solutions Business of Marvell, so
-berlin SoCs are now Synaptics' SoCs now.
-
----------------------------------------------------------------
-
-Work in progress statement:
-
-Device tree files and bindings applying to Marvell Berlin SoCs and boards are
-considered "unstable". Any Marvell Berlin device tree binding may change at any
-time. Be sure to use a device tree binary and a kernel image generated from the
-same source tree.
-
-Please refer to Documentation/devicetree/bindings/ABI.rst for a definition of a
-stable binding/ABI.
-
----------------------------------------------------------------
-
-Boards with a SoC of the Marvell Berlin family, e.g. Armada 1500
-shall have the following properties:
-
-* Required root node properties:
-compatible: must contain "marvell,berlin"
-
-In addition, the above compatible shall be extended with the specific
-SoC and board used. Currently known SoC compatibles are:
- "marvell,berlin2" for Marvell Armada 1500 (BG2, 88DE3100),
- "marvell,berlin2cd" for Marvell Armada 1500-mini (BG2CD, 88DE3005)
- "marvell,berlin2ct" for Marvell Armada ? (BG2CT, 88DE????)
- "marvell,berlin2q" for Marvell Armada 1500-pro (BG2Q, 88DE3114)
- "marvell,berlin3" for Marvell Armada ? (BG3, 88DE????)
-
-* Example:
-
-/ {
- model = "Sony NSZ-GS7";
- compatible = "sony,nsz-gs7", "marvell,berlin2", "marvell,berlin";
-
- ...
-}
-
-* Marvell Berlin CPU control bindings
-
-CPU control register allows various operations on CPUs, like resetting them
-independently.
-
-Required properties:
-- compatible: should be "marvell,berlin-cpu-ctrl"
-- reg: address and length of the register set
-
-Example:
-
-cpu-ctrl@f7dd0000 {
- compatible = "marvell,berlin-cpu-ctrl";
- reg = <0xf7dd0000 0x10000>;
-};
-
-* Marvell Berlin2 chip control binding
-
-Marvell Berlin SoCs have a chip control register set providing several
-individual registers dealing with pinmux, padmux, clock, reset, and secondary
-CPU boot address. Unfortunately, the individual registers are spread among the
-chip control registers, so there should be a single DT node only providing the
-different functions which are described below.
-
-Required properties:
-- compatible:
- * the first and second values must be:
- "simple-mfd", "syscon"
-- reg: address and length of following register sets for
- BG2/BG2CD: chip control register set
- BG2Q: chip control register set and cpu pll registers
-
-* Marvell Berlin2 system control binding
-
-Marvell Berlin SoCs have a system control register set providing several
-individual registers dealing with pinmux, padmux, and reset.
-
-Required properties:
-- compatible:
- * the first and second values must be:
- "simple-mfd", "syscon"
-- reg: address and length of the system control register set
-
-Example:
-
-chip: chip-control@ea0000 {
- compatible = "simple-mfd", "syscon";
- reg = <0xea0000 0x400>;
-
- /* sub-device nodes */
-};
-
-sysctrl: system-controller@d000 {
- compatible = "simple-mfd", "syscon";
- reg = <0xd000 0x100>;
-
- /* sub-device nodes */
-};

- This is a Pad configuration node. On Tegra SOCs a pad is a set of
- pins which are configured as a group. The pin grouping is a fixed
- attribute of the hardware. The PMC can be used to set pad power state
- and signaling voltage. A pad can be either in active or power down mode.
- The support for power state and signaling voltage configuration varies
- depending on the pad in question. 3.3V and 1.8V signaling voltages
- are supported on pins where software controllable signaling voltage
- switching is available.
-
- The pad configuration state nodes are placed under the pmc node and they
- are referred to by the pinctrl client properties. For more information
- see Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt.
- The pad name should be used as the value of the pins property in pin
- configuration nodes.
-
- The following pads are present on Tegra124 and Tegra132
- audio, bb, cam, comp, csia, csb, cse, dsi, dsib, dsic, dsid, hdmi, hsic,
- hv, lvds, mipi-bias, nand, pex-bias, pex-clk1, pex-clk2, pex-cntrl,
- sdmmc1, sdmmc3, sdmmc4, sys_ddc, uart, usb0, usb1, usb2, usb_bias.
-
- The following pads are present on Tegra210
- audio, audio-hv, cam, csia, csib, csic, csid, csie, csif, dbg,

-* APM X-Gene 6.0 Gb/s SATA host controller nodes
-
-SATA host controller nodes are defined to describe on-chip Serial ATA
-controllers. Each SATA controller (pair of ports) have its own node.
-
-Required properties:
-- compatible : Shall contain:
- * "apm,xgene-ahci"
-- reg : First memory resource shall be the AHCI memory
- resource.
- Second memory resource shall be the host controller
- core memory resource.
- Third memory resource shall be the host controller
- diagnostic memory resource.
- 4th memory resource shall be the host controller
- AXI memory resource.
- 5th optional memory resource shall be the host
- controller MUX memory resource if required.
-- interrupts : Interrupt-specifier for SATA host controller IRQ.
-- clocks : Reference to the clock entry.
-- phys : A list of phandles + phy-specifiers, one for each
- entry in phy-names.
-- phy-names : Should contain:
- * "sata-phy" for the SATA 6.0Gbps PHY
-
-Optional properties:
-- dma-coherent : Present if dma operations are coherent
-- status : Shall be "ok" if enabled or "disabled" if disabled.
- Default is "ok".
-
-Example:
- sataclk: sataclk {
- compatible = "fixed-clock";
- #clock-cells = <1>;

+description:
+ The Maxim MAX6958/6959 7-segment LED display controller provides
+ an I2C interface to up to four 7-segment LED digits. The MAX6959,
+ in comparison to MAX6958, adds input support. Type of the chip can
+ be autodetected via specific register read, and hence the features
+ may be enabled in the driver at run-time, in case they are requested
+ via Device Tree. A given hardware is simple and does not provide
+ any additional pins, such as reset or power enable.

-Freescale Reference Board Bindings
-
-This document describes device tree bindings for various devices that
-exist on some Freescale reference boards.
-
-* Board Control and Status (BCSR)
-
-Required properties:
-
- - compatible : Should be "fsl,<board>-bcsr"
- - reg : Offset and length of the register set for the device
-
-Example:
-
- bcsr@f8000000 {
- compatible = "fsl,mpc8360mds-bcsr";
- reg = <f8000000 8000>;
- };
-
-* Freescale on-board FPGA
-
-This is the memory-mapped registers for on board FPGA.
-
-Required properties:
-- compatible: should be a board-specific string followed by a string
- indicating the type of FPGA. Example:
- "fsl,<board>-fpga", "fsl,fpga-pixis", or
- "fsl,<board>-fpga", "fsl,fpga-qixis"
-- reg: should contain the address and the length of the FPGA register set.
-
-Optional properties:
-- interrupts: should specify event (wakeup) IRQ.
-
-Example (P1022DS):
-
- board-control@3,0 {
- compatible = "fsl,p1022ds-fpga", "fsl,fpga-ngpixis";
- reg = <3 0 0x30>;
- interrupt-parent = <&mpic>;
- interrupts = <8 8 0 0>;
- };
-
-Example (LS2080A-RDB):
-
- cpld@3,0 {
- compatible = "fsl,ls2080ardb-fpga", "fsl,fpga-qixis";
- reg = <0x3 0 0x10000>;
- };
-
-* Freescale on-board FPGA connected on I2C bus
-
-Some Freescale boards like BSC9132QDS have on board FPGA connected on
-the i2c bus.
-
-Required properties:
-- compatible: Should be a board-specific string followed by a string
- indicating the type of FPGA. Example:
- "fsl,<board>-fpga", "fsl,fpga-qixis-i2c"
-- reg: Should contain the address of the FPGA
-
-Example:
- fpga: fpga@66 {
- compatible = "fsl,bsc9132qds-fpga", "fsl,fpga-qixis-i2c";
- reg = <0x66>;
- };
-
-* Freescale on-board CPLD
-
-Some Freescale boards like T1040RDB have an on board CPLD connected.
-
-Required properties:
-- compatible: Should be a board-specific string like "fsl,<board>-cpld"
- Example:
- "fsl,t1040rdb-cpld", "fsl,t1042rdb-cpld", "fsl,t1042rdb_pi-cpld"
-- reg: should describe CPLD registers
-
-Example:
- cpld@3,0 {
- compatible = "fsl,t1040rdb-cpld";
- reg = <3 0 0x300>;
- };

-Device tree bindings for i.MX Wireless External Interface Module (WEIM)
-
-The term "wireless" does not imply that the WEIM is literally an interface
-without wires. It simply means that this module was originally designed for
-wireless and mobile applications that use low-power technology.
-
-The actual devices are instantiated from the child nodes of a WEIM node.
-
-Required properties:
-
- - compatible: Should contain one of the following:
- "fsl,imx1-weim"
- "fsl,imx27-weim"
- "fsl,imx51-weim"
- "fsl,imx50-weim"
- "fsl,imx6q-weim"
- - reg: A resource specifier for the register space
- (see the example below)
- - clocks: the clock, see the example below.
- - #address-cells: Must be set to 2 to allow memory address translation
- - #size-cells: Must be set to 1 to allow CS address passing
- - ranges: Must be set up to reflect the memory layout with four
- integer values for each chip-select line in use:
-
- <cs-number> 0 <physical address of mapping> <size>
-
-Optional properties:
-
- - fsl,weim-cs-gpr: For "fsl,imx50-weim" and "fsl,imx6q-weim" type of
- devices, it should be the phandle to the system General
- Purpose Register controller that contains WEIM CS GPR
- register, e.g. IOMUXC_GPR1 on i.MX6Q. IOMUXC_GPR1[11:0]
- should be set up as one of the following 4 possible
- values depending on the CS space configuration.
-
- IOMUXC_GPR1[11:0] CS0 CS1 CS2 CS3
- ---------------------------------------------
- 05 128M 0M 0M 0M
- 033 64M 64M 0M 0M
- 0113 64M 32M 32M 0M
- 01111 32M 32M 32M 32M
-
- In case that the property is absent, the reset value or
- what bootloader sets up in IOMUXC_GPR1[11:0] will be
- used.
-
- - fsl,burst-clk-enable For "fsl,imx50-weim" and "fsl,imx6q-weim" type of
- devices, the presence of this property indicates that
- the weim bus should operate in Burst Clock Mode.
-
- - fsl,continuous-burst-clk Make Burst Clock to output continuous clock.
- Without this option Burst Clock will output clock
- only when necessary. This takes effect only if
- "fsl,burst-clk-enable" is set.
-
-Timing property for child nodes. It is mandatory, not optional.
-
- - fsl,weim-cs-timing: The timing array, contains timing values for the
- child node. We get the CS indexes from the address
- ranges in the child node's "reg" property.
- The number of registers depends on the selected chip:
- For i.MX1, i.MX21 ("fsl,imx1-weim") there are two
- registers: CSxU, CSxL.
- For i.MX25, i.MX27, i.MX31 and i.MX35 ("fsl,imx27-weim")
- there are three registers: CSCRxU, CSCRxL, CSCRxA.
- For i.MX50, i.MX53 ("fsl,imx50-weim"),
- i.MX51 ("fsl,imx51-weim") and i.MX6Q ("fsl,imx6q-weim")
- there are six registers: CSxGCR1, CSxGCR2, CSxRCR1,
- CSxRCR2, CSxWCR1, CSxWCR2.
-
-Example for an imx6q-sabreauto board, the NOR flash connected to the WEIM:
-
- weim: weim@21b8000 {
- compatible = "fsl,imx6q-weim";
- reg = <0x021b8000 0x4000>;
- clocks = <&clks 196>;
- #address-cells = <2>;
- #size-cells = <1>;
- ranges = <0 0 0x08000000 0x08000000>;
- fsl,weim-cs-gpr = <&gpr>;
-
- nor@0,0 {
- compatible = "cfi-flash";
- reg = <0 0 0x02000000>;
- #address-cells = <1>;
- #size-cells = <1>;
- bank-width = <2>;
- fsl,weim-cs-timing = <0x00620081 0x00000001 0x1c022000
- 0x0000c000 0x1404a38e 0x00000000>;
- };
- };
-
-Example for an imx6q-based board, a multi-chipselect device connected to WEIM:
-
-In this case, both chip select 0 and 1 will be configured with the same timing
-array values.
-
- weim: weim@21b8000 {
- compatible = "fsl,imx6q-weim";
- reg = <0x021b8000 0x4000>;
- clocks = <&clks 196>;
- #address-cells = <2>;
- #size-cells = <1>;
- ranges = <0 0 0x08000000 0x02000000

-Qualcomm External Bus Interface 2 (EBI2)
-
-The EBI2 contains two peripheral blocks: XMEM and LCDC. The XMEM handles any
-external memory (such as NAND or other memory-mapped peripherals) whereas
-LCDC handles LCD displays.
-
-As it says it connects devices to an external bus interface, meaning address
-lines (up to 9 address lines so can only address 1KiB external memory space),
-data lines (16 bits), OE (output enable), ADV (address valid, used on some
-NOR flash memories), WE (write enable). This on top of 6 different chip selects
-(CS0 thru CS5) so that in theory 6 different devices can be connected.
-
-Apparently this bus is clocked at 64MHz. It has dedicated pins on the package
-and the bus can only come out on these pins, however if some of the pins are
-unused they can be left unconnected or remuxed to be used as GPIO or in some
-cases other orthogonal functions as well.
-
-Also CS1 and CS2 has -A and -B signals. Why they have that is unclear to me.
-
-The chip selects have the following memory range assignments. This region of
-memory is referred to as "Chip Peripheral SS FPB0" and is 168MB big.
-
-Chip Select Physical address base
-CS0 GPIO134 0x1a800000-0x1b000000 (8MB)
-CS1 GPIO39 (A) / GPIO123 (B) 0x1b000000-0x1b800000 (8MB)
-CS2 GPIO40 (A) / GPIO124 (B) 0x1b800000-0x1c000000 (8MB)
-CS3 GPIO133 0x1d000000-0x25000000 (128 MB)
-CS4 GPIO132 0x1c800000-0x1d000000 (8MB)
-CS5 GPIO131 0x1c000000-0x1c800000 (8MB)
-
-The APQ8060 Qualcomm Application Processor User Guide, 80-N7150-14 Rev. A,
-August 6, 2012 contains some incomplete documentation of the EBI2.
-
-FIXME: the manual mentions "write precharge cycles" and "precharge cycles".
-We have not been able to figure out which bit fields these correspond to
-in the hardware, or what valid values exist. The current hypothesis is that
-this is something just used on the FAST chip selects and that the SLOW
-chip selects are understood fully. There is also a "byte device enable"
-flag somewhere for 8bit memories.
-
-FIXME: The chipselects have SLOW and FAST configuration registers. It's a bit
-unclear what this means, if they are mutually exclusive or can be used
-together, or if some chip selects are hardwired to be FAST and others are SLOW
-by design.
-
-The XMEM registers are totally undocumented but could be partially decoded
-because the Cypress AN49576 Antioch Westbridge apparently has suspiciously
-similar register layout, see: http://www.cypress.com/file/105771/download
-
-Required properties:
-- compatible: should be one of:
- "qcom,msm8660-ebi2"
- "qcom,apq8060-ebi2"
-- #address-cells: should be <2>: the first cell is the chipselect,
- the second cell is the offset inside the memory range
-- #size-cells: should be <1>
-- ranges: should be set to:
- ranges = <0 0x0 0x1a800000 0x00800000>,
- <1 0x0 0x1b000000 0x00800000>,

- <4 0x0 0x1c800000 0x00800000>,
- <5 0x0 0x1c000000 0x00800000>;
-- reg: two ranges of registers: EBI2 config and XMEM config areas
-- reg-names: should be "ebi2", "xmem"
-- clocks: two clocks, EBI_2X and EBI
-- clock-names: should be "ebi2x", "ebi2"
-
-Optional subnodes:
-- Nodes inside the EBI2 will be considered device nodes.
-
-The following optional properties are properties that can be tagged onto
-any device subnode. We are assuming that there can be only ONE device per
-chipselect subnode, else the properties will become ambiguous.
-
-Optional properties arrays for SLOW chip selects:
-- qcom,xmem-recovery-cycles: recovery cycles is the time the memory continues to
- drive the data bus after OE is de-asserted, in order to avoid contention on
- the data bus. They are inserted when reading one CS and switching to another
- CS or read followed by write on the same CS. Valid values 0 thru 15. Minimum
- value is actually 1, so a value of 0 will still yield 1 recovery cycle.
-- qcom,xmem-write-hold-cycles: write hold cycles, these are extra cycles
- inserted after every write minimum 1. The data out is driven from the time
- WE is asserted until CS is asserted. With a hold of 1 (value = 0), the CS
- stays active for 1 extra cycle etc. Valid values 0 thru 15.
-- qcom,xmem-write-delta-cycles: initial latency for write cycles inserted for
- the first write to a page or burst memory. Valid values 0 thru 255.
-- qcom,xmem-read-delta-cycles: initial latency for read cycles inserted for the
- first read to a page or burst memory. Valid values 0 thru 255.
-- qcom,xmem-write-wait-cycles: number of wait cycles for every write access, 0=1
- cycle. Valid values 0 thru 15.
-- qcom,xmem-read-wait-cycles: number of wait cycles for every read access, 0=1
- cycle. Valid values 0 thru 15.
-
-Optional properties arrays for FAST chip selects:
-- qcom,xmem-address-hold-enable: this is a boolean property stating that we
- shall hold the address for an extra cycle to meet hold time requirements
- with ADV assertion.
-- qcom,xmem-adv-to-oe-recovery-cycles: the number of cycles elapsed before an OE
- assertion, with respect to the cycle where ADV (address valid) is asserted.
- 2 means 2 cycles between ADV and OE. Valid values 0, 1, 2 or 3.
-- qcom,xmem-read-hold-cycles: the length in cycles of the first segment of a
- read transfer. For a single read transfer this will be the time from CS
- assertion to OE assertion. Valid values 0 thru 15.
-

+
+description: |
+ CDX bus controller for AMD devices is implemented to dynamically
+ detect CDX bus and devices using the firmware.
+ The CDX bus manages multiple FPGA based hardware devices, which
+ can support network, crypto or any other specialized type of
+ devices. These FPGA based devices can be added/modified dynamically
+ on run-time.
+
+ All devices on the CDX bus will have a unique streamid (for IOMMU)
+ and a unique device ID (for MSI) corresponding to a requestor ID
+ (one to one associated with the device). The streamid and deviceid
+ are used to configure SMMU and GIC-ITS respectively.
+
+ iommu-map property is used to define the set of stream ids
+ corresponding to each device and the associated IOMMU.
+
+ The MSI writes are accompanied by sideband data (Device ID).
+ The msi-map property is used to associate the devices with the
+ device ID as well as the associated ITS controller.
+
+ rproc property (xlnx,rproc) is used to identify the remote processor
+ with which APU (Application Processor Unit) interacts to find out
+ the bus and device configuration.

+ LLCC (Last Level Cache Controller) provides last level of cache memory in SoC,
+ that can be shared by multiple clients. Clients here are different cores in the
+ SoC, the idea is to minimize the local caches at the clients and migrate to
+ common pool of memory. Cache memory is divided into partitions called slices
+ which are assigned to clients. Clients can query the slice details, activate
+ and deactivate them.

-* Actions Semi Owl Clock Management Unit (CMU)
-
-The Actions Semi Owl Clock Management Unit generates and supplies clock
-to various controllers within the SoC. The clock binding described here is
-applicable to S900, S700 and S500 SoC's.
-
-Required Properties:
-
-- compatible: should be one of the following,
- "actions,s900-cmu"
- "actions,s700-cmu"
- "actions,s500-cmu"
-- reg: physical base address of the controller and length of memory mapped
- region.
-- clocks: Reference to the parent clocks ("hosc", "losc")
-- #clock-cells: should be 1.
-- #reset-cells: should be 1.
-
-Each clock is assigned an identifier, and client nodes can use this identifier
-to specify the clock which they consume.
-
-All available clocks are defined as preprocessor macros in corresponding
-dt-bindings/clock/actions,s900-cmu.h or actions,s700-cmu.h or
-actions,s500-cmu.h header and can be used in device tree sources.
-
-External clocks:
-
-The hosc clock used as input for the plls is generated outside the SoC. It is
-expected that it is defined using standard clock bindings as "hosc".
-
-Actions Semi S900 CMU also requires one more clock:
- - "losc" - internal low frequency oscillator
-
-Example: Clock Management Unit node:
-
- cmu: clock-controller@e0160000 {
- compatible = "actions,s900-cmu";
- reg = <0x0 0xe0160000 0x0 0x1000>;
- clocks = <&hosc>, <&losc>;
- #clock-cells = <1>;
- #reset-cells = <1>;
- };
-
-Example: UART controller node that consumes clock generated by the clock
-management unit:
-
- uart: serial@e012a000 {
- compatible = "actions,s900-uart", "actions,owl-uart";
- reg = <0x0 0xe012a000 0x0 0x2000>;
- interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&cmu CLK_UART5>;

-Alphascale Clock Controller
-
-The ACC (Alphascale Clock Controller) is responsible of choising proper
-clock source, setting deviders and clock gates.
-
-Required properties for the ACC node:
- - compatible: must be "alphascale,asm9260-clock-controller"
- - reg: must contain the ACC register base and size
- - #clock-cells : shall be set to 1.
-
-Simple one-cell clock specifier format is used, where the only cell is used
-as an index of the clock inside the provider.
-It is encouraged to use dt-binding for clock index definitions. SoC specific
-dt-binding should be included to the device tree descriptor. For example
-Alphascale ASM9260:
-#include <dt-bindings/clock/alphascale,asm9260.h>
-
-This binding contains two types of clock providers:
- _AHB_ - AHB gate;
- _SYS_ - adjustable clock source. Not all peripheral have _SYS_ clock provider.
-All clock specific details can be found in the SoC documentation.

-- fixed-divider : If clocks have a fixed divider value, use this property.
-- clk-gate : For "socfpga-gate-clk", clk-gate contains the gating register
- and the bit index.
-- div-reg : For "socfpga-gate-clk" and "socfpga-periph-clock", div-reg contains
- the divider register, bit shift, and width.
-- clk-phase : For the sdmmc_clk, contains the value of the clock phase that controls
- the SDMMC CIU clock. The first value is the clk_sample(smpsel), and the second
- value is the cclk_in_drv(drvsel). The clk-phase is used to enable the correct
- hold/delay times that is needed for the SD/MMC CIU clock. The values of both
- can be 0-315 degrees, in 45 degree increments.

-* Amlogic AXG Audio Clock Controllers
-
-The Amlogic AXG audio clock controller generates and supplies clock to the
-other elements of the audio subsystem, such as fifos, i2s, spdif and pdm
-devices.
-
-Required Properties:
-
-- compatible : should be "amlogic,axg-audio-clkc" for the A113X and A113D,
- "amlogic,g12a-audio-clkc" for G12A,
- "amlogic,sm1-audio-clkc" for S905X3.
-- reg : physical base address of the clock controller and length of
- memory mapped region.
-- clocks : a list of phandle + clock-specifier pairs for the clocks listed
- in clock-names.
-- clock-names : must contain the following:
- * "pclk" - Main peripheral bus clock
- may contain the following:
- * "mst_in[0-7]" - 8 input plls to generate clock signals
- * "slv_sclk[0-9]" - 10 slave bit clocks provided by external
- components.
- * "slv_lrclk[0-9]" - 10 slave sample clocks provided by external
- components.
-- resets : phandle of the internal reset line
-- #clock-cells : should be 1.
-- #reset-cells : should be 1 on the g12a (and following) soc family
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume. All available clocks are defined as
-preprocessor macros in the dt-bindings/clock/axg-audio-clkc.h header and can be
-used in device tree sources.
-
-Example:
-
-clkc_audio: clock-controller@0 {
- compatible = "amlogic,axg-audio-clkc";
- reg = <0x0 0x0 0x0 0xb4>;
- #clock-cells = <1>;

-* Amlogic GXBB AO Clock and Reset Unit
-
-The Amlogic GXBB AO clock controller generates and supplies clock to various
-controllers within the Always-On part of the SoC.
-
-Required Properties:
-
-- compatible: value should be different for each SoC family as :
- - GXBB (S905) : "amlogic,meson-gxbb-aoclkc"
- - GXL (S905X, S905D) : "amlogic,meson-gxl-aoclkc"
- - GXM (S912) : "amlogic,meson-gxm-aoclkc"
- - AXG (A113D, A113X) : "amlogic,meson-axg-aoclkc"
- - G12A (S905X2, S905D2, S905Y2) : "amlogic,meson-g12a-aoclkc"
- followed by the common "amlogic,meson-gx-aoclkc"
-- clocks: list of clock phandle, one for each entry clock-names.
-- clock-names: should contain the following:
- * "xtal" : the platform xtal
- * "mpeg-clk" : the main clock controller mother clock (aka clk81)
- * "ext-32k-0" : external 32kHz reference #0 if any (optional)
- * "ext-32k-1" : external 32kHz reference #1 if any (optional - gx only)
- * "ext-32k-2" : external 32kHz reference #2 if any (optional - gx only)
-
-- #clock-cells: should be 1.
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume. All available clocks are defined as
-preprocessor macros in the dt-bindings/clock/gxbb-aoclkc.h header and can be
-used in device tree sources.
-
-- #reset-cells: should be 1.

-Each reset is assigned an identifier and client nodes can use this identifier
-to specify the reset which they consume. All available resets are defined as
-preprocessor macros in the dt-bindings/reset/gxbb-aoclkc.h header and can be
-used in device tree sources.
-
-Parent node should have the following properties :
-- compatible: "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd"
-- reg: base address and size of the AO system control register space.
-
-Example: AO Clock controller node:
-
-ao_sysctrl: sys-ctrl@0 {
- compatible = "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd";
- reg = <0x0 0x0 0x0 0x100>;
-
- clkc_AO: clock-controller {
- compatible = "amlogic,meson-gxbb-aoclkc", "amlogic,meson-gx-aoclkc";
- #clock-cells = <1>;
- #reset-cells = <1>;
- clocks = <&xtal>, <&clkc CLKID_CLK81>;
- clock-names = "xtal", "mpeg-clk";
- };
-
-Example: UART controller node that consumes the clock and reset generated
- by the clock controller:
-
- uart_AO: serial@4c0 {
- compatible = "amlogic,meson-uart";

-* Amlogic GXBB Clock and Reset Unit
-
-The Amlogic GXBB clock controller generates and supplies clock to various
-controllers within the SoC.
-
-Required Properties:
-
-- compatible: should be:
- "amlogic,gxbb-clkc" for GXBB SoC,
- "amlogic,gxl-clkc" for GXL and GXM SoC,
- "amlogic,axg-clkc" for AXG SoC.
- "amlogic,g12a-clkc" for G12A SoC.
- "amlogic,g12b-clkc" for G12B SoC.
- "amlogic,sm1-clkc" for SM1 SoC.
-- clocks : list of clock phandle, one for each entry clock-names.
-- clock-names : should contain the following:
- * "xtal": the platform xtal
-
-- #clock-cells: should be 1.
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume. All available clocks are defined as
-preprocessor macros in the dt-bindings/clock/gxbb-clkc.h header and can be
-used in device tree sources.
-
-Parent node should have the following properties :
-- compatible: "syscon", "simple-mfd, and "amlogic,meson-gx-hhi-sysctrl" or
- "amlogic,meson-axg-hhi-sysctrl"
-- reg: base address and size of the HHI system control register space.
-
-Example: Clock controller node:
-
-sysctrl: system-controller@0 {
- compatible = "amlogic,meson-gx-hhi-sysctrl", "syscon", "simple-mfd";
- reg = <0 0 0 0x400>;
-
- clkc: clock-controller {
- #clock-cells = <1>;
- compatible = "amlogic,gxbb-clkc";
- clocks = <&xtal>;
- clock-names = "xtal";
- };
-};
-
-Example: UART controller node that consumes the clock generated by the clock
- controller:
-
- uart_AO: serial@c81004c0 {
- compatible = "amlogic,meson-uart";
- reg = <0xc81004c0 0x14>;
- interrupts = <0 90 1>;
- clocks = <&clkc CLKID_CLK81>;

-* Time Base Generator Clock bindings for Marvell Armada 37xx SoCs
-
-Marvell Armada 37xx SoCs provide Time Base Generator clocks which are
-used as parent clocks for the peripheral clocks.
-
-The TBG clock consumer should specify the desired clock by having the
-clock ID in its "clocks" phandle cell.
-
-The following is a list of provided IDs and clock names on Armada 3700:
- 0 = TBG A P
- 1 = TBG B P
- 2 = TBG A S
- 3 = TBG B S
-
-Required properties:
-- compatible : shall be "marvell,armada-3700-tbg-clock"
-- reg : must be the register address of North Bridge PLL register
-- #clock-cells : from common clock binding; shall be set to 1
-
-Example:
-
-tbg: tbg@13200 {
- compatible = "marvell,armada-3700-tbg-clock";
- reg = <0x13200 0x1000>;
- clocks = <&xtalclk>;

-There are two external inputs to the main clock controller which should be
-provided using the common clock bindings.
-- "sys_refclk": External 50 Mhz oscillator (required)
-- "i2s_refclk": Alternate audio reference clock (optional).
-
-Main clock controller

-Required properties:
-- #clock-cells: Should be <1>
- See dt-bindings/clock/axis,artpec6-clkctrl.h for the list of valid identifiers.
-- compatible: Should be "axis,artpec6-clkctrl"
-- reg: Must contain the base address and length of the system controller
-- clocks: Must contain a phandle entry for each clock in clock-names
-- clock-names: Must include the external oscillator ("sys_refclk"). Optional
- ones are the audio reference clock ("i2s_refclk") and the audio fractional
- dividers ("frac_clk0" and "frac_clk1").

+description: |
+ ARTPEC-8 clock controller is comprised of several CMU (Clock Management Unit)
+ units, generating clocks for different domains. Those CMU units are modeled
+ as separate device tree nodes, and might depend on each other.
+ The root clock in that root tree is an external clock: OSCCLK (25 MHz).
+ This external clock must be defined as a fixed-rate clock in dts.
+
+ CMU_CMU is a top-level CMU, where all base clocks are prepared using PLLs and
+ dividers; all other clocks of function blocks (other CMUs) are usually
+ derived from CMU_CMU.
+
+ Each clock is assigned an identifier and client nodes can use this identifier
+ to specify the clock which they consume. All clocks available for usage
+ in clock consumer nodes are defined as preprocessor macros in
+ 'include/dt-bindings/clock/axis,artpec8-clk.h' header.

-Broadcom BCM2835 CPRMAN clocks
-
-This binding uses the common clock binding:
- Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-The CPRMAN clock controller generates clocks in the audio power domain
-of the BCM2835. There is a level of PLLs deriving from an external
-oscillator, a level of PLL dividers that produce channels off of the
-few PLLs, and a level of mostly-generic clock generators sourcing from
-the PLL channels. Most other hardware components source from the
-clock generators, but a few (like the ARM or HDMI) will source from
-the PLL dividers directly.
-
-Required properties:
-- compatible: should be one of the following,
- "brcm,bcm2711-cprman"
- "brcm,bcm2835-cprman"
-- #clock-cells: Should be <1>. The permitted clock-specifier values can be
- found in include/dt-bindings/clock/bcm2835.h
-- reg: Specifies base physical address and size of the registers
-- clocks: phandles to the parent clocks used as input to the module, in
- the following order:
-
- - External oscillator
- - DSI0 byte clock
- - DSI0 DDR2 clock
- - DSI0 DDR clock
- - DSI1 byte clock
- - DSI1 DDR2 clock
- - DSI1 DDR clock
-
- Only external oscillator is required. The DSI clocks may
- not be present, in which case their children will be
- unusable.
-
-Example:
-
- clk_osc: clock@3 {
- compatible = "fixed-clock";
- reg = <3>;
- #clock-cells = <0>;
- clock-output-names = "osc";
- clock-frequency = <19200000>;

-Broadcom BCM53573 ILP clock
-===========================
-
-This binding uses the common clock binding:
- Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-This binding is used for ILP clock (sometimes referred as "slow clock")
-on Broadcom BCM53573 devices using Cortex-A7 CPU.
-
-ILP's rate has to be calculated on runtime and it depends on ALP clock
-which has to be referenced.
-
-This clock is part of PMU (Power Management Unit), a Broadcom's device
-handing power-related aspects. Its node must be sub-node of the PMU
-device.
-
-Required properties:
-- compatible: "brcm,bcm53573-ilp"
-- clocks: has to reference an ALP clock
-- #clock-cells: should be <0>
-- clock-output-names: from common clock bindings, should contain clock
- name
-
-Example:
-
-pmu@18012000 {
- compatible = "simple-mfd", "syscon";
- reg = <0x18012000 0x00001000>;

-Broadcom Kona Family Clocks
-
-This binding is associated with Broadcom SoCs having "Kona" style
-clock control units (CCUs). A CCU is a clock provider that manages
-a set of clock signals. Each CCU is represented by a node in the
-device tree.
-
-This binding uses the common clock binding:
- Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible
- Shall have a value of the form "brcm,<model>-<which>-ccu",
- where <model> is a Broadcom SoC model number and <which> is
- the name of a defined CCU. For example:
- "brcm,bcm11351-root-ccu"
- The compatible strings used for each supported SoC family
- are defined below.
-- reg
- Shall define the base and range of the address space
- containing clock control registers
-- #clock-cells
- Shall have value <1>. The permitted clock-specifier values
- are defined below.
-- clock-output-names
- Shall be an ordered list of strings defining the names of
- the clocks provided by the CCU.
-
-Device tree example:
-
- slave_ccu: slave_ccu {
- compatible = "brcm,bcm11351-slave-ccu";
- reg = <0x3e011000 0x0f00>;

+description: |
+ Freescale QorIQ chips take primary clocking input from the external
+ SYSCLK signal. The SYSCLK input (frequency) is multiplied using
+ multiple phase locked loops (PLL) to create a variety of frequencies
+ which can then be passed to a variety of internal logic, including
+ cores and peripheral IP blocks.
+ Please refer to the Reference Manual for details.
+
+ All references to "1.0" and "2.0" refer to the QorIQ chassis version to

+description: |
+ Google GS101 clock controller is comprised of several CMU units, generating
+ clocks for different domains. Those CMU units are modeled as separate device
+ tree nodes, and might depend on each other. The root clock in that clock tree
+ is OSCCLK (24.576 MHz). That external clock must be defined as a fixed-rate
+ clock in dts.
+
+ CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
+ dividers; all other leaf clocks (other CMUs) are usually derived from CMU_TOP.
+
+ Each clock is assigned an identifier and client nodes can use this identifier
+ to specify the clock which they consume. All clocks available for usage
+ in clock consumer nodes are defined as preprocessor macros in
+ 'dt-bindings/clock/gs101.h' header.

+description: |
+ Pistachio has four clock controllers (core clock, peripheral clock, peripheral
+ general control, and top general control) which are instantiated individually
+ from the device-tree.
+
+ Core clock controller:
+
+ The core clock controller generates clocks for the CPU, RPU (WiFi + BT
+ co-processor), audio, and several peripherals.
+
+ Peripheral clock controller:
+
+ The peripheral clock controller generates clocks for the DDR, ROM, and other
+ peripherals. The peripheral system clock ("periph_sys") generated by the core
+ clock controller is the input clock to the peripheral clock controller.
+
+ Peripheral general control:
+
+ The peripheral general control block generates system interface clocks and
+ resets for various peripherals. It also contains miscellaneous peripheral
+ control registers.
+
+ Top-level general control:
+
+ The top-level general control block contains miscellaneous control registers
+ and gates for the external clocks "audio_clk_in" and "enet_clk_in".

-* NXP LPC1850 Clock Generation Unit (CGU)
-
-The CGU generates multiple independent clocks for the core and the
-peripheral blocks of the LPC18xx. Each independent clock is called
-a base clock and itself is one of the inputs to the two Clock
-Control Units (CCUs) which control the branch clocks to the
-individual peripherals.
-
-The CGU selects the inputs to the clock generators from multiple
-clock sources, controls the clock generation, and routes the outputs
-of the clock generators through the clock source bus to the output
-stages. Each output stage provides an independent clock source and
-corresponds to one of the base clocks for the LPC18xx.
-
- - Above text taken from NXP LPC1850 User Manual.
-
-
-This binding uses the common clock binding:
- Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible:
- Should be "nxp,lpc1850-cgu"
-- reg:
- Shall define the base and range of the address space
- containing clock control registers
-- #clock-cells:
- Shall have value <1>. The permitted clock-specifier values
- are the base clock numbers defined below.
-- clocks:
- Shall contain a list of phandles for the external input
- sources to the CGU. The list shall be in the following
- order: xtal, 32khz, enet_rx_clk, enet_tx_clk, gp_clkin.
-- clock-indices:
- Shall be an ordered list of numbers defining the base clock
- number provided by the CGU.
-- clock-output-names:
- Shall be an ordered list of strings defining the names of
- the clocks provided by the CGU.
-
-Which base clocks that are available on the CGU depends on the
-specific LPC part. Base clocks are numbered from 0 to 27.
-
-Number: Name: Description:
- 0 BASE_SAFE_CLK Base safe clock (always on) for WWDT

-* NXP LPC1850 CREG clocks
-
-The NXP LPC18xx/43xx CREG (Configuration Registers) block contains
-control registers for two low speed clocks. One of the clocks is a
-32 kHz oscillator driver with power up/down and clock gating. Next
-is a fixed divider that creates a 1 kHz clock from the 32 kHz osc.
-
-These clocks are used by the RTC and the Event Router peripherials.
-The 32 kHz can also be routed to other peripherials to enable low
-power modes.
-
-This binding uses the common clock binding:
- Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible:
- Should be "nxp,lpc1850-creg-clk"
-- #clock-cells:
- Shall have value <1>.
-- clocks:
- Shall contain a phandle to the fixed 32 kHz crystal.
-
-The creg-clk node must be a child of the creg syscon node.
-
-The following clocks are available from the clock node.
-
-Clock ID Name
- 0 1 kHz clock
- 1 32 kHz Oscillator
-
-Example:
-soc {
- creg: syscon@40043000 {

-Device Tree Clock bindings for Marvell Berlin
-
-This binding uses the common clock binding[1].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Clock related registers are spread among the chip control registers. Berlin
-clock node should be a sub-node of the chip controller node. Marvell Berlin2
-(BG2, BG2CD, BG2Q) SoCs share the same IP for PLLs and clocks, with some
-minor differences in features and register layout.
-
-Required properties:
-- compatible: must be "marvell,berlin2-clk" or "marvell,berlin2q-clk"
-- #clock-cells: must be 1
-- clocks: must be the input parent clock phandle
-- clock-names: name of the input parent clock
- Allowed clock-names for the reference clocks are
- "refclk" for the SoCs oscillator input on all SoCs,
- and SoC-specific input clocks for
- BG2/BG2CD: "video_ext0" for the external video clock input
-
-
-Example:
-
-chip_clk: clock {
- compatible = "marvell,berlin2q-clk";
-
- #clock-cells = <1>;
- clocks = <&refclk>;

-Devicetree bindings for Maxim MAX9485 Programmable Audio Clock Generator
-
-This device exposes 4 clocks in total:
-
-- MAX9485_MCLKOUT: A gated, buffered output of the input clock of 27 MHz
-- MAX9485_CLKOUT: A PLL that can be configured to 16 different discrete
- frequencies
-- MAX9485_CLKOUT[1,2]: Two gated outputs for MAX9485_CLKOUT
-
-MAX9485_CLKOUT[1,2] are children of MAX9485_CLKOUT which upchain all rate set
-requests.
-
-Required properties:
-- compatible: "maxim,max9485"
-- clocks: Input clock, must provice 27.000 MHz
-- clock-names: Must be set to "xclk"
-- #clock-cells: From common clock binding; shall be set to 1
-
-Optional properties:
-- reset-gpios: GPIO descriptor connected to the #RESET input pin
-- vdd-supply: A regulator node for Vdd
-- clock-output-names: Name of output clocks, as defined in common clock
- bindings
-
-If not explicitly set, the output names are "mclkout", "clkout", "clkout1"
-and "clkout2".
-
-Clocks are defined as preprocessor macros in the dt-binding header.
-
-Example:
-
- #include <dt-bindings/clock/maxim,max9485.h>
-
- xo-27mhz: xo-27mhz {
- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <27000000>;
- };
-
- &i2c0 {
- max9485: audio-clock@63 {
- reg = <0x63>;
- compatible = "maxim,max9485";
- clock-names = "xclk";
- clocks = <&xo-27mhz>;
- reset-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;
- vdd-supply = <&3v3-reg>;
- #clock-cells = <1>;
- };
- };
-
- // Clock consumer node
-
- foo@0 {
- compatible = "bar,foo";
- /* ... */
- clock-names = "foo-input-clk";
- clocks = <&max9485 MAX9485_CLKOUT1>;

+ Phandle to the "Hardware Voter" (HWV), as named in the vendor
+ documentation for MT8196/MT6991.
+
+ The HWV is a SoC-internal fixed-function MCU used to collect votes from
+ both the Application Processor and other remote processors within the SoC.
+ It is intended to transparently enable or disable hardware resources (such
+ as power domains or clocks) based on internal vote aggregation handled by
+ the MCU's internal state machine.
+
+ However, in practice, this design is incomplete. While the HWV performs
+ some internal vote aggregation,software is still required to
+ - Manually enable power supplies externally, if present and if required
+ - Manually enable parent clocks via direct MMIO writes to clock controllers
+ - Enable the FENC after the clock has been ungated via direct MMIO
+ writes to clock controllers
+
+ As such, the HWV behaves more like a hardware-managed clock reference
+ counter than a true voter. Furthermore, it is not a separate
+ controller. It merely serves as an alternative interface to the same
+ underlying clock or power controller. Actual control still requires
+ direct access to the controller's own MMIO register space, in
+ addition to writing to the HWV's MMIO region.
+
+ For this reason, a custom phandle is used here - drivers need to directly
+ access the HWV MMIO region in a syscon-like fashion, due to how the
+ hardware is wired. This differs from true hardware voting systems, which
+ typically do not require custom phandles and rely instead on generic APIs
+ (clocks, power domains, interconnects).
+
+ The name "hardware-voter" is retained to match vendor documentation, but
+ this should not be reused or misunderstood as a proper voting mechanism.

+ provided as well as derived clocks for the bus and the peripherals.
+
+ Each clock is assigned an identifier and client nodes use this identifier
+ to specify the clock which they consume.

-Microchip PIC32 Clock Controller Binding
-----------------------------------------
-Microchip clock controller is consists of few oscillators, PLL, multiplexer
-and few divider modules.
-
-This binding uses common clock bindings.
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible: shall be "microchip,pic32mzda-clk".
-- reg: shall contain base address and length of clock registers.
-- #clock-cells: shall be 1.
-
-Optional properties:
-- microchip,pic32mzda-sosc: shall be added only if platform has
- secondary oscillator connected.
-
-Example:
- rootclk: clock-controller@1f801200 {
- compatible = "microchip,pic32mzda-clk";
- reg = <0x1f801200 0x200>;
- #clock-cells = <1>;
- /* optional */
- microchip,pic32mzda-sosc;
- };
-
-
-The clock consumer shall specify the desired clock-output of the clock
-controller (as defined in [2]) by specifying output-id in its "clock"
-phandle cell.
-[2] include/dt-bindings/clock/microchip,pic32-clock.h
-
-For example for UART2:
-uart2: serial@2 {
- compatible = "microchip,pic32mzda-uart";
- reg = <>;
- interrupts = <>;
- clocks = <&rootclk PB2CLK>;

-* Nuvoton NPCM7XX Clock Controller
-
-Nuvoton Poleg BMC NPCM7XX contains an integrated clock controller, which
-generates and supplies clocks to all modules within the BMC.
-
-External clocks:
-
-There are six fixed clocks that are generated outside the BMC. All clocks are of
-a known fixed value that cannot be changed. clk_refclk, clk_mcbypck and
-clk_sysbypck are inputs to the clock controller.
-clk_rg1refck, clk_rg2refck and clk_xin are external clocks suppling the
-network. They are set on the device tree, but not used by the clock module. The
-network devices use them directly.
-Example can be found below.
-
-All available clocks are defined as preprocessor macros in:
-dt-bindings/clock/nuvoton,npcm7xx-clock.h
-and can be reused as DT sources.
-
-Required Properties of clock controller:
-
- - compatible: "nuvoton,npcm750-clk" : for clock controller of Nuvoton
- Poleg BMC NPCM750
-
- - reg: physical base address of the clock controller and length of
- memory mapped region.
-
- - #clock-cells: should be 1.
-
-Example: Clock controller node:
-
- clk: clock-controller@f0801000 {
- compatible = "nuvoton,npcm750-clk";
- #clock-cells = <1>;
- reg = <0xf0801000 0x1000>;
- clock-names = "refclk", "sysbypck", "mcbypck";
- clocks = <&clk_refclk>, <&clk_sysbypck>, <&clk_mcbypck>;
- };
-
-Example: Required external clocks for network:
-
- /* external reference clock */
- clk_refclk: clk-refclk {
- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <25000000>;
- clock-output-names = "refclk";
- };
-
- /* external reference clock for cpu. float in normal operation */
- clk_sysbypck: clk-sysbypck {
- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <800000000>;
- clock-output-names = "sysbypck";
- };
-
- /* external reference clock for MC. float in normal operation */
- clk_mcbypck: clk-mcbypck {
- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <800000000>;
- clock-output-names = "mcbypck";
- };
-
- /* external clock signal rg1refck, supplied by the phy */
- clk_rg1refck: clk-rg1refck {
- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <125000000>;
- clock-output-names = "clk_rg1refck";
- };
-
- /* external clock signal rg2refck, supplied by the phy */
- clk_rg2refck: clk-rg2refck {
- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <125000000>;
- clock-output-names = "clk_rg2refck";

- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <50000000>;
- clock-output-names = "clk_xin";
- };
-
-
-Example: GMAC controller node that consumes two clocks: a generated clk by the
-clock controller and a fixed clock from DT (clk_rg1refck).
-
- ethernet0: ethernet@f0802000 {
- compatible = "snps,dwmac";

+title: NXP LPC1850 Clock Generation Unit (CGU)
+
+description: >
+ The CGU generates multiple independent clocks for the core and the
+ peripheral blocks of the LPC18xx. Each independent clock is called
+ a base clock and itself is one of the inputs to the two Clock
+ Control Units (CCUs) which control the branch clocks to the
+ individual peripherals.
+
+ The CGU selects the inputs to the clock generators from multiple
+ clock sources, controls the clock generation, and routes the outputs
+ of the clock generators through the clock source bus to the output
+ stages. Each output stage provides an independent clock source and
+ corresponds to one of the base clocks for the LPC18xx.

-Imagination Technologies Pistachio SoC clock controllers
-========================================================
-
-Pistachio has four clock controllers (core clock, peripheral clock, peripheral
-general control, and top general control) which are instantiated individually
-from the device-tree.
-
-External clocks:
-----------------
-
-There are three external inputs to the clock controllers which should be
-defined with the following clock-output-names:
-- "xtal": External 52Mhz oscillator (required)
-- "audio_clk_in": Alternate audio reference clock (optional)
-- "enet_clk_in": Alternate ethernet PHY clock (optional)
-
-Core clock controller:
-----------------------
-
-The core clock controller generates clocks for the CPU, RPU (WiFi + BT
-co-processor), audio, and several peripherals.
-
-Required properties:
-- compatible: Must be "img,pistachio-clk".
-- reg: Must contain the base address and length of the core clock controller.
-- #clock-cells: Must be 1. The single cell is the clock identifier.
- See dt-bindings/clock/pistachio-clk.h for the list of valid identifiers.
-- clocks: Must contain an entry for each clock in clock-names.
-- clock-names: Must include "xtal" (see "External clocks") and
- "audio_clk_in_gate", "enet_clk_in_gate" which are generated by the
- top-level general control.
-
-Example:
- clk_core: clock-controller@18144000 {
- compatible = "img,pistachio-clk";
- reg = <0x18144000 0x800>;
- clocks = <&xtal>, <&cr_top EXT_CLK_AUDIO_IN>,
- <&cr_top EXT_CLK_ENET_IN>;
- clock-names = "xtal", "audio_clk_in_gate", "enet_clk_in_gate";
-
- #clock-cells = <1>;
- };
-
-Peripheral clock controller:
-----------------------------
-
-The peripheral clock controller generates clocks for the DDR, ROM, and other
-peripherals. The peripheral system clock ("periph_sys") generated by the core
-clock controller is the input clock to the peripheral clock controller.
-
-Required properties:
-- compatible: Must be "img,pistachio-periph-clk".
-- reg: Must contain the base address and length of the peripheral clock
- controller.
-- #clock-cells: Must be 1. The single cell is the clock identifier.
- See dt-bindings/clock/pistachio-clk.h for the list of valid identifiers.
-- clocks: Must contain an entry for each clock in clock-names.
-- clock-names: Must include "periph_sys", the peripheral system clock generated
- by the core clock controller.
-
-Example:
- clk_periph: clock-controller@18144800 {
- compatible = "img,pistachio-clk-periph";
- reg = <0x18144800 0x800>;
- clocks = <&clk_core CLK_PERIPH_SYS>;
- clock-names = "periph_sys";
-
- #clock-cells = <1>;
- };
-
-Peripheral general control:
----------------------------
-
-The peripheral general control block generates system interface clocks and
-resets for various peripherals. It also contains miscellaneous peripheral
-control registers. The system clock ("sys") generated by the peripheral clock
-controller is the input clock to the system clock controller.
-
-Required properties:
-- compatible: Must include "img,pistachio-periph-cr" and "syscon".
-- reg: Must contain the base address and length of the peripheral general
- control registers.
-- #clock-cells: Must be 1. The single cell is the clock identifier.
- See dt-bindings/clock/pistachio-clk.h for the list of valid identifiers.
-- clocks: Must contain an entry for each clock in clock-names.
-- clock-names: Must include "sys", the system clock generated by the peripheral
- clock controller.
-
-Example:
- cr_periph: syscon@18144800 {
- compatible = "img,pistachio-cr-periph", "syscon";
- reg = <0x18148000 0x1000>;
- clocks = <&clock_periph PERIPH_CLK_PERIPH_SYS>;
- clock-names = "sys";
-
- #clock-cells = <1>;
- };
-
-Top-level general control:
---------------------------
-
-The top-level general control block contains miscellaneous control registers and
-gates for the external clocks "audio_clk_in" and "enet_clk_in".
-
-Required properties:
-- compatible: Must include "img,pistachio-cr-top" and "syscon".
-- reg: Must contain the base address and length of the top-level
- control registers.
-- clocks: Must contain an entry for each clock in clock-names.
-- clock-names: Two optional clocks, "audio_clk_in" and "enet_clk_in" (see
- "External clocks").
-- #clock-cells: Must be 1. The single cell is the clock identifier.
- See dt-bindings/clock/pistachio-clk.h for the list of valid identifiers.
-
-Example:
- cr_top: syscon@18144800 {
- compatible = "img,pistachio-cr-top", "syscon";
- reg = <0x18149000 0x200>;
- clocks = <&audio_refclk>, <&ext_enet_in>;
- clock-names = "audio_clk_in", "enet_clk_in";
-
- #clock-cells = <1>;

+description:
+ The CMN (or common) PLL clock controller expects a reference

+ networking hardware include PPE (packet process engine), PCS
+ and the externally connected switch or PHY devices. The CMN
+ PLL block also outputs fixed rate clocks to GCC. The PLL's
+ primary function is to enable fixed rate output clocks for
+ networking hardware functions used with the IPQ SoC.

-* Clock Block on Freescale QorIQ Platforms
-
-Freescale QorIQ chips take primary clocking input from the external
-SYSCLK signal. The SYSCLK input (frequency) is multiplied using
-multiple phase locked loops (PLL) to create a variety of frequencies
-which can then be passed to a variety of internal logic, including
-cores and peripheral IP blocks.
-Please refer to the Reference Manual for details.
-
-All references to "1.0" and "2.0" refer to the QorIQ chassis version to
-which the chip complies.
-
-Chassis Version Example Chips
---------------- -------------
-1.0 p4080, p5020, p5040
-2.0 t4240, b4860
-
-1. Clock Block Binding
-
-Required properties:
-- compatible: Should contain a chip-specific clock block compatible
- string and (if applicable) may contain a chassis-version clock
- compatible string.
-
- Chip-specific strings are of the form "fsl,<chip>-clockgen", such as:
- * "fsl,p2041-clockgen"
- * "fsl,p3041-clockgen"
- * "fsl,p4080-clockgen"
- * "fsl,p5020-clockgen"
- * "fsl,p5040-clockgen"
- * "fsl,t1023-clockgen"
- * "fsl,t1024-clockgen"
- * "fsl,t1040-clockgen"
- * "fsl,t1042-clockgen"
- * "fsl,t2080-clockgen"
- * "fsl,t2081-clockgen"
- * "fsl,t4240-clockgen"
- * "fsl,b4420-clockgen"
- * "fsl,b4860-clockgen"
- * "fsl,ls1012a-clockgen"
- * "fsl,ls1021a-clockgen"
- * "fsl,ls1028a-clockgen"
- * "fsl,ls1043a-clockgen"
- * "fsl,ls1046a-clockgen"
- * "fsl,ls1088a-clockgen"
- * "fsl,ls2080a-clockgen"
- * "fsl,lx2160a-clockgen"
- Chassis-version clock strings include:
- * "fsl,qoriq-clockgen-1.0": for chassis 1.0 clocks
- * "fsl,qoriq-clockgen-2.0": for chassis 2.0 clocks
-- reg: Describes the address of the device's resources within the
- address space defined by its parent bus, and resource zero
- represents the clock register set
-
-Optional properties:
-- ranges: Allows valid translation between child's address space and
- parent's. Must be present if the device has sub-nodes.
-- #address-cells: Specifies the number of cells used to represent
- physical base addresses. Must be present if the device has
- sub-nodes and set to 1 if present
-- #size-cells: Specifies the number of cells used to represent
- the size of an address. Must be present if the device has
- sub-nodes and set to 1 if present
-- clock-frequency: Input system clock frequency (SYSCLK)
-- clocks: If clock-frequency is not specified, sysclk may be provided
- as an input clock. Either clock-frequency or clocks must be
- provided.
- A second input clock, called "coreclk", may be provided if
- core PLLs are based on a different input clock from the
- platform PLL.
-- clock-names: Required if a coreclk is present. Valid names are
- "sysclk" and "coreclk".
-
-2. Clock Provider
-
-The clockgen node should act as a clock provider, though in older device
-trees the children of the clockgen node are the clock providers.
-
-When the clockgen node is a clock provider, #clock-cells = <2>.
-The first cell of the clock specifier is the clock type, and the
-second cell is the clock index for the specified type.
-
- Type# Name Index Cell
- 0 sysclk must be 0
- 1 cmux index (n in CLKCnCSR)
- 2 hwaccel index (n in CLKCGnHWACSR)
- 3 fman 0 for fm1, 1 for fm2
- 4 platform pll n=pll/(n+1). For example, when n=1,
- that means output_freq=PLL_freq/2.
- 5 coreclk must be 0
-
-3. Example
-
- clockgen: global-utilities@e1000 {
- compatible = "fsl,p5020-clockgen", "fsl,qoriq-clockgen-1.0";
- clock-frequency = <133333333>;
- reg = <0xe1000 0x1000>;
- #clock-cells = <2>;
- };
-
- fman@400000 {
- ...
- clocks = <&clockgen 3 0>;
- ...
- };
-}
-4. Legacy Child Nodes
-
-NOTE: These nodes are deprecated. Kernels should continue to support
-device trees with these nodes, but new device trees should not use them.
-
-Most of the bindings are from the common clock binding[1].
- [1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible : Should include one of the following:
- * "fsl,qoriq-core-pll-1.0" for core PLL clocks (v1.0)
- * "fsl,qoriq-core-pll-2.0" for core PLL clocks (v2.0)
- * "fsl,qoriq-core-mux-1.0" for core mux clocks (v1.0)
- * "fsl,qoriq-core-mux-2.0" for core mux clocks (v2.0)
- * "fsl,qoriq-sysclk-1.0": for input system clock (v1.0).
- It takes parent's clock-frequency as its clock.
- * "fsl,qoriq-sysclk-2.0": for input system clock (v2.0).
- It takes parent's clock-frequency as its clock.
- * "fsl,qoriq-platform-pll-1.0" for the platform PLL clock (v1.0)
- * "fsl,qoriq-platform-pll-2.0" for the platform PLL clock (v2.0)
-- #clock-cells: From common clock binding. The number of cells in a
- clock-specifier. Should be <0> for "fsl,qoriq-sysclk-[1,2].0"
- clocks, or <1> for "fsl,qoriq-core-pll-[1,2].0" clocks.
- For "fsl,qoriq-core-pll-[1,2].0" clocks, the single
- clock-specifier cell may take the following values:
- * 0 - equal to the PLL frequency
- * 1 - equal to the PLL frequency divided by 2
- * 2 - equal to the PLL frequency divided by 4
-
-Recommended properties:
-- clocks: Should be the phandle of input parent clock
-- clock-names: From common clock binding, indicates the clock name
-- clock-output-names: From common clock binding, indicates the names of
- output clocks
-- reg: Should be the offset and length of clock block base address.
- The length should be 4.

+
+description: |
+ The 5P35023 is a VersaClock programmable clock generator and
+ is designed for low-power, consumer, and high-performance PCI
+ express applications. The 5P35023 device is a three PLL
+ architecture design, and each PLL is individually programmable
+ and allowing for up to 6 unique frequency outputs.
+
+ An internal OTP memory allows the user to store the configuration
+ in the device. After power up, the user can change the device register
+ settings through the I2C interface when I2C mode is selected.
+
+ The driver can read a full register map from the DT, and will use that
+ register map to initialize the attached part (via I2C) when the system
+ boots. Any configuration not supported by the common clock framework
+ must be done via the full register map, including optimized settings.

-* Rockchip RK3328 Clock and Reset Unit
-
-The RK3328 clock controller generates and supplies clock to various
-controllers within the SoC and also implements a reset controller for SoC
-peripherals.
-
-Required Properties:
-
-- compatible: should be "rockchip,rk3328-cru"
-- reg: physical base address of the controller and length of memory mapped
- region.
-- #clock-cells: should be 1.
-- #reset-cells: should be 1.
-
-Optional Properties:
-
-- rockchip,grf: phandle to the syscon managing the "general register files"
- If missing pll rates are not changeable, due to the missing pll lock status.
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume. All available clocks are defined as
-preprocessor macros in the dt-bindings/clock/rk3328-cru.h headers and can be
-used in device tree sources. Similar macros exist for the reset sources in
-these files.
-
-External clocks:
-
-There are several clocks that are generated outside the SoC. It is expected
-that they are defined using standard clock bindings with following
-clock-output-names:
- - "xin24m" - crystal input - required,
- - "clkin_i2s" - external I2S clock - optional,
- - "gmac_clkin" - external GMAC clock - optional
- - "phy_50m_out" - output clock of the pll in the mac phy
- - "hdmi_phy" - output clock of the hdmi phy pll - optional
-
-Example: Clock controller node:
-
- cru: clock-controller@ff440000 {
- compatible = "rockchip,rk3328-cru";
- reg = <0x0 0xff440000 0x0 0x1000>;
- rockchip,grf = <&grf>;
-
- #clock-cells = <1>;
- #reset-cells = <1>;
- };
-
-Example: UART controller node that consumes the clock generated by the clock
- controller:
-
- uart0: serial@ff120000 {
- compatible = "snps,dw-apb-uart";
- reg = <0xff120000 0x100>;
- interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>;
- reg-shift = <2>;
- reg-io-width = <4>;
- clocks = <&cru SCLK_UART0>;

+description: |
+ The RK3328 clock controller generates and supplies clocks to various
+ controllers within the SoC and also implements a reset controller for SoC
+ peripherals.
+ Each clock is assigned an identifier and client nodes can use this identifier
+ to specify the clock which they consume. All available clocks are defined as
+ preprocessor macros in the dt-bindings/clock/rk3328-cru.h headers and can be
+ used in device tree sources. Similar macros exist for the reset sources in
+ these files.
+ There are several clocks that are generated outside the SoC. It is expected
+ that they are defined using standard clock bindings with following
+ clock-output-names:
+ - "xin24m" - crystal input - required,
+ - "clkin_i2s" - external I2S clock - optional,
+ - "gmac_clkin" - external GMAC clock - optional
+ - "phy_50m_out" - output clock of the pll in the mac phy
+ - "hdmi_phy" - output clock of the hdmi phy pll - optional

+description: |
+ Exynos2200 clock controller is comprised of several CMU units, generating
+ clocks for different domains. Those CMU units are modeled as separate device
+ tree nodes, and might depend on each other. The root clocks in that root tree
+ are two external clocks: XTCXO (76.8 MHz) and RTCCLK (32768 Hz). XTCXO must be
+ defined as a fixed-rate clock in dts, whereas RTCCLK originates from PMIC.
+
+ CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
+ dividers; all other clocks of function blocks (other CMUs) are usually
+ derived from CMU_TOP.
+
+ Each clock is assigned an identifier and client nodes can use this identifier
+ to specify the clock which they consume. All clocks available for usage
+ in clock consumer nodes are defined as preprocessor macros in
+ 'include/dt-bindings/clock/samsung,exynos2200-cmu.h' header.

+description: |
+ Exynos8895 clock controller is comprised of several CMU units, generating
+ clocks for different domains. Those CMU units are modeled as separate device
+ tree nodes, and might depend on each other. The root clock in that root tree
+ is an external clock: OSCCLK (26 MHz). This external clock must be defined
+ as a fixed-rate clock in dts.
+
+ CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
+ dividers; all other clocks of function blocks (other CMUs) are usually
+ derived from CMU_TOP.
+
+ Each clock is assigned an identifier and client nodes can use this identifier
+ to specify the clock which they consume. All clocks available for usage
+ in clock consumer nodes are defined as preprocessor macros in
+ 'include/dt-bindings/clock/samsung,exynos8895.h' header.

-* Samsung S3C64xx Clock Controller
-
-The S3C64xx clock controller generates and supplies clock to various controllers
-within the SoC. The clock binding described here is applicable to all SoCs in
-the S3C64xx family.
-
-Required Properties:
-
-- compatible: should be one of the following.
- - "samsung,s3c6400-clock" - controller compatible with S3C6400 SoC.
- - "samsung,s3c6410-clock" - controller compatible with S3C6410 SoC.
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-
-- #clock-cells: should be 1.
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume. Some of the clocks are available only
-on a particular S3C64xx SoC and this is specified where applicable.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/samsung,s3c64xx-clock.h header and can be used in device
-tree sources.
-
-External clocks:
-
-There are several clocks that are generated outside the SoC. It is expected
-that they are defined using standard clock bindings with following
-clock-output-names:
- - "fin_pll" - PLL input clock (xtal/extclk) - required,
- - "xusbxti" - USB xtal - required,
- - "iiscdclk0" - I2S0 codec clock - optional,
- - "iiscdclk1" - I2S1 codec clock - optional,
- - "iiscdclk2" - I2S2 codec clock - optional,
- - "pcmcdclk0" - PCM0 codec clock - optional,
- - "pcmcdclk1" - PCM1 codec clock - optional, only S3C6410.
-
-Example: Clock controller node:
-
- clock: clock-controller@7e00f000 {
- compatible = "samsung,s3c6410-clock";
- reg = <0x7e00f000 0x1000>;
- #clock-cells = <1>;
- };
-
-Example: Required external clocks:
-
- fin_pll: clock-fin-pll {
- compatible = "fixed-clock";
- clock-output-names = "fin_pll";
- clock-frequency = <12000000>;
- #clock-cells = <0>;
- };
-
- xusbxti: clock-xusbxti {
- compatible = "fixed-clock";
- clock-output-names = "xusbxti";
- clock-frequency = <48000000>;
- #clock-cells = <0>;
- };
-
-Example: UART controller node that consumes the clock generated by the clock
- controller (refer to the standard clock bindings for information about
- "clocks" and "clock-names" properties):
-
- uart0: serial@7f005000 {
- compatible = "samsung,s3c6400-uart";
- reg = <0x7f005000 0x100>;

-
-The Si5341 and Si5340 are programmable i2c clock generators with up to 10 output
-clocks. The chip contains a PLL that sources 5 (or 4) multisynth clocks, which
-in turn can be directed to any of the 10 (or 4) outputs through a divider.
-The internal structure of the clock generators can be found in [2].
-The Si5345 is similar to the Si5341 with the addition of fractional input
-dividers and automatic input selection, as described in [3].
-The Si5342 and Si5344 are smaller versions of the Si5345, with 2 or 4 outputs.
-
-The driver can be used in "as is" mode, reading the current settings from the
-chip at boot, in case you have a (pre-)programmed device. If the PLL is not
-configured when the driver probes, it assumes the driver must fully initialize
-it.
-
-The device type, speed grade and revision are determined runtime by probing.
-
-The driver currently does not support any fancy input configurations. They can
-still be programmed into the chip and the driver will leave them "as is".
-
-==I2C device node==
-
-Required properties:
-- compatible: shall be one of the following:
- "silabs,si5340" - Si5340 A/B/C/D
- "silabs,si5341" - Si5341 A/B/C/D
- "silabs,si5342" - Si5342 A/B/C/D
- "silabs,si5344" - Si5344 A/B/C/D
- "silabs,si5345" - Si5345 A/B/C/D
-- reg: i2c device address, usually 0x74
-- #clock-cells: from common clock binding; shall be set to 2.
- The first value is "0" for outputs, "1" for synthesizers.
- The second value is the output or synthesizer index.
-- clocks: from common clock binding; list of parent clock handles,
- corresponding to inputs. Use a fixed clock for the "xtal" input.
- At least one must be present.
-- clock-names: One of: "xtal", "in0", "in1", "in2"
-
-Optional properties:
-- vdd-supply: Regulator node for VDD
-- vdda-supply: Regulator node for VDDA
-- vdds-supply: Regulator node for VDDS
-- silabs,pll-m-num, silabs,pll-m-den: Numerator and denominator for PLL
- feedback divider. Must be such that the PLL output is in the valid range. For
- example, to create 14GHz from a 48MHz xtal, use m-num=14000 and m-den=48. Only
- the fraction matters, using 3500 and 12 will deliver the exact same result.
- If these are not specified, and the PLL is not yet programmed when the driver
- probes, the PLL will be set to 14GHz.
-- silabs,reprogram: When present, the driver will always assume the device must
- be initialized, and always performs the soft-reset routine. Since this will
- temporarily stop all output clocks, don't do this if the chip is generating
- the CPU clock for example.
-- silabs,xaxb-ext-clk: When present, indicates that the XA/XB pins are used
- in EXTCLK (external reference clock) rather than XTAL (crystal) mode.
-- interrupts: Interrupt for INTRb pin.
-- silabs,iovdd-33: When present, indicates that the I2C lines are using 3.3V
- rather than 1.8V thresholds.
-- vddoX-supply (where X is an output index): Regulator node for VDDO for the
- specified output. The driver selects the output VDD_SEL setting based on this
- voltage.
-- #address-cells: shall be set to 1.
-- #size-cells: shall be set to 0.
-
-
-== Child nodes: Outputs ==
-
-The child nodes list the output clocks.
-
-Each of the clock outputs can be overwritten individually by using a child node.
-If a child node for a clock output is not set, the configuration remains
-unchanged.
-
-Required child node properties:
-- reg: number of clock output.
-
-Optional child node properties:
-- silabs,format: Output format, one of:
- 1 = differential (defaults to LVDS levels)
- 2 = low-power (defaults to HCSL levels)
- 4 = LVCMOS
-- silabs,common-mode: Manually override output common mode, see [2] for values
-- silabs,amplitude: Manually override output amplitude, see [2] for values
-- silabs,synth-master: boolean. If present, this output is allowed to change the
- multisynth frequency dynamically.
-- silabs,silabs,disable-high: boolean. If set, the clock output is driven HIGH
- when disabled, otherwise it's driven LOW.

-Spreadtrum SC9860 Clock Binding
-------------------------
-
-Required properties:
-- compatible: should contain the following compatible strings:
- - "sprd,sc9860-pmu-gate"
- - "sprd,sc9860-pll"
- - "sprd,sc9860-ap-clk"
- - "sprd,sc9860-aon-prediv"
- - "sprd,sc9860-apahb-gate"
- - "sprd,sc9860-aon-gate"
- - "sprd,sc9860-aonsecure-clk"
- - "sprd,sc9860-agcp-gate"
- - "sprd,sc9860-gpu-clk"
- - "sprd,sc9860-vsp-clk"
- - "sprd,sc9860-vsp-gate"
- - "sprd,sc9860-cam-clk"
- - "sprd,sc9860-cam-gate"
- - "sprd,sc9860-disp-clk"
- - "sprd,sc9860-disp-gate"
- - "sprd,sc9860-apapb-gate"
-
-- #clock-cells: must be 1
-
-- clocks : Should be the input parent clock(s) phandle for the clock, this
- property here just simply shows which clock group the clocks'
- parents are in, since each clk node would represent many clocks
- which are defined in the driver. The detailed dependency
- relationship (i.e. how many parents and which are the parents)
- are implemented in driver code.
-
-Optional properties:
-
-- reg: Contain the registers base address and length. It must be configured
- only if no 'sprd,syscon' under the node.
-
-- sprd,syscon: phandle to the syscon which is in the same address area with
- the clock, and so we can get regmap for the clocks from the
- syscon device.
-
-Example:
-
- pmu_gate: pmu-gate {
- compatible = "sprd,sc9860-pmu-gate";
- sprd,syscon = <&pmu_regs>;
- clocks = <&ext_26m>;
- #clock-cells = <1>;
- };
-
- pll: pll {
- compatible = "sprd,sc9860-pll";
- sprd,syscon = <&ana_regs>;
- clocks = <&pmu_gate 0>;
- #clock-cells = <1>;
- };
-
- ap_clk: clock-controller@20000000 {
- compatible = "sprd,sc9860-ap-clk";
- reg = <0 0x20000000 0 0x400>;
- clocks = <&ext_26m>, <&pll 0>,
- <&pmu_gate 0>;
- #clock-cells = <1>;

-STMicroelectronics STM32 Reset and Clock Controller
-===================================================
-
-The RCC IP is both a reset and a clock controller.
-
-Please refer to clock-bindings.txt for common clock controller binding usage.
-Please also refer to reset.txt for common reset controller binding usage.
-
-Required properties:
-- compatible: Should be:
- "st,stm32f42xx-rcc"
- "st,stm32f469-rcc"
- "st,stm32f746-rcc"
- "st,stm32f769-rcc"
-
-- reg: should be register base and length as documented in the
- datasheet
-- #reset-cells: 1, see below
-- #clock-cells: 2, device nodes should specify the clock in their "clocks"
- property, containing a phandle to the clock device node, an index selecting
- between gated clocks and other clocks and an index specifying the clock to
- use.
-- clocks: External oscillator clock phandle
- - high speed external clock signal (HSE)
- - external I2S clock (I2S_CKIN)
-
-Example:
-
- rcc: rcc@40023800 {
- #reset-cells = <1>;
- #clock-cells = <2>
- compatible = "st,stm32f42xx-rcc", "st,stm32-rcc";
- reg = <0x40023800 0x400>;
- clocks = <&clk_hse>, <&clk_i2s_ckin>;
- };
-
-Specifying gated clocks
-=======================
-
-The primary index must be set to 0.
-
-The secondary index is the bit number within the RCC register bank, starting
-from the first RCC clock enable register (RCC_AHB1ENR, address offset 0x30).
-
-It is calculated as: index = register_offset / 4 * 32 + bit_offset.
-Where bit_offset is the bit offset within the register (LSB is 0, MSB is 31).
-
-To simplify the usage and to share bit definition with the reset and clock
-drivers of the RCC IP, macros are available to generate the index in
-human-readble format.
-
-For STM32F4 series, the macro are available here:
- - include/dt-bindings/mfd/stm32f4-rcc.h
-
-Example:
-
- /* Gated clock, AHB1 bit 0 (GPIOA) */
- ... {
- clocks = <&rcc 0 STM32F4_AHB1_CLOCK(GPIOA)>
- };
-
- /* Gated clock, AHB2 bit 4 (CRYP) */
- ... {
- clocks = <&rcc 0 STM32F4_AHB2_CLOCK(CRYP)>
- };
-
-Specifying other clocks
-=======================
-
-The primary index must be set to 1.
-
-The secondary index is bound with the following magic numbers:
-
- 0 SYSTICK
- 1 FCLK
- 2 CLK_LSI (low-power clock source)
- 3 CLK_LSE (generated from a 32.768 kHz low-speed external
- crystal or ceramic resonator)
- 4 CLK_HSE_RTC (HSE division factor for RTC clock)
- 5 CLK_RTC (real-time clock)
- 6 PLL_VCO_I2S (vco frequency of I2S pll)
- 7 PLL_VCO_SAI (vco frequency of SAI pll)
- 8 CLK_LCD (LCD-TFT)
- 9 CLK_I2S (I2S clocks)
- 10 CLK_SAI1 (audio clocks)
- 11 CLK_SAI2
- 12 CLK_I2SQ_PDIV (post divisor of pll i2s q divisor)
- 13 CLK_SAIQ_PDIV (post divisor of pll sai q divisor)
-
- 14 CLK_HSI (Internal ocscillator clock)
- 15 CLK_SYSCLK (System Clock)
- 16 CLK_HDMI_CEC (HDMI-CEC clock)
- 17 CLK_SPDIF (SPDIF-Rx clock)
- 18 CLK_USART1 (U(s)arts clocks)
- 19 CLK_USART2
- 20 CLK_USART3
- 21 CLK_UART4
- 22 CLK_UART5
- 23 CLK_USART6
- 24 CLK_UART7
- 25 CLK_UART8
- 26 CLK_I2C1 (I2S clocks)
- 27 CLK_I2C2
- 28 CLK_I2C3
- 29 CLK_I2C4
- 30 CLK_LPTIMER (LPTimer1 clock)
- 31 CLK_PLL_SRC
- 32 CLK_DFSDM1
- 33 CLK_ADFSDM1
- 34 CLK_F769_DSI
-)
-
-Example:
-
- /* Misc clock, FCLK */
- ... {
- clocks = <&rcc 1 STM32F4_APB1_CLOCK(TIM2)>
- };
-
-
-Specifying softreset control of devices
-=======================================
-
-Device nodes should specify the reset channel required in their "resets"
-property, containing a phandle to the reset device node and an index specifying
-which channel to use.
-The index is the bit number within the RCC registers bank, starting from RCC
-base address.
-It is calculated as: index = register_offset / 4 * 32 + bit_offset.
-Where bit_offset is the bit offset within the register.
-For example, for CRC reset:
- crc = AHB1RSTR_offset / 4 * 32 + CRCRST_bit_offset = 0x10 / 4 * 32 + 12 = 140
-
-example:
-
- timer2 {
- resets = <&rcc STM32F4_APB1_RESET(TIM2)>;
- };

-Please refer to clock-bindings.txt for common clock controller binding usage.
-Please also refer to reset.txt for common reset controller binding usage.
-
-Required properties:
-- compatible: Should be:
- "st,stm32h743-rcc"
-
-- reg: should be register base and length as documented in the
- datasheet
-
-- #reset-cells: 1, see below

-- #clock-cells : from common clock binding; shall be set to 1
-
-- clocks: External oscillator clock phandle
- - high speed external clock signal (HSE)
- - low speed external clock signal (LSE)
- - external I2S clock (I2S_CKIN)
-
-Optional properties:
-- st,syscfg: phandle for pwrcfg, mandatory to disable/enable backup domain
- write protection (RTC clock).
-
-Example:
-
- rcc: reset-clock-controller@58024400 {
- compatible = "st,stm32h743-rcc", "st,stm32-rcc";
- reg = <0x58024400 0x400>;

- #clock-cells = <1>;
- clocks = <&clk_hse>, <&clk_lse>, <&clk_i2s_ckin>;
-
- st,syscfg = <&pwrcfg>;
-};
-
-The peripheral clock consumer should specify the desired clock by
-having the clock ID in its "clocks" phandle cell.
-
-Example:
-
- timer5: timer@40000c00 {
- compatible = "st,stm32-timer";
- reg = <0x40000c00 0x400>;
- interrupts = <50>;

+
+description:
+ These PLLs are high speed, low jitter frequency synthesizers in the JH7110.
+ Each PLL works in integer mode or fraction mode, with configuration
+ registers in the sys syscon. So the PLLs node should be a child of
+ SYS-SYSCON node.
+ The formula for calculating frequency is
+ Fvco = Fref * (NI + NF) / M / Q1

-Binding for TI divider clock
-
-Binding status: Unstable - ABI compatibility may be broken in the future
-
-This binding uses the common clock binding[1]. It assumes a
-register-mapped adjustable clock rate divider that does not gate and has
-only one input clock or parent. By default the value programmed into
-the register is one less than the actual divisor value. E.g:
-
-register value actual divisor value
-0 1
-1 2
-2 3
-
-This assumption may be modified by the following optional properties:
-
-ti,index-starts-at-one - valid divisor values start at 1, not the default
-of 0. E.g:
-register value actual divisor value
-1 1
-2 2
-3 3
-
-ti,index-power-of-two - valid divisor values are powers of two. E.g:
-register value actual divisor value
-0 1
-1 2
-2 4
-
-Additionally an array of valid dividers may be supplied like so:
-
- ti,dividers = <4>, <8>, <0>, <16>;
-
-Which will map the resulting values to a divisor table by their index:
-register value actual divisor value
-0 4
-1 8
-2 <invalid divisor, skipped>
-3 16
-
-Any zero value in this array means the corresponding bit-value is invalid
-and must not be used.
-
-The binding must also provide the register to control the divider and
-unless the divider array is provided, min and max dividers. Optionally
-the number of bits to shift that mask, if necessary. If the shift value
-is missing it is the same as supplying a zero shift.
-
-This binding can also optionally provide support to the hardware autoidle
-feature, see [2].

-
-Optional properties:
-- clock-output-names : from common clock binding.
-- ti,dividers : array of integers defining divisors
-- ti,bit-shift : number of bits to shift the divider value, defaults to 0
-- ti,min-div : min divisor for dividing the input clock rate, only
- needed if the first divisor is offset from the default value (1)
-- ti,max-div : max divisor for dividing the input clock rate, only needed
- if ti,dividers is not defined.
-- ti,index-starts-at-one : valid divisor programming starts at 1, not zero,
- only valid if ti,dividers is not defined.
-- ti,index-power-of-two : valid divisor programming must be a power of two,
- only valid if ti,dividers is not defined.
-- ti,autoidle-shift : bit shift of the autoidle enable bit for the clock,
- see [2]
-- ti,invert-autoidle-bit : autoidle is enabled by setting the bit to 0,
- see [2]
-- ti,set-rate-parent : clk_set_rate is propagated to parent

-Binding for TI mux clock.
-
-Binding status: Unstable - ABI compatibility may be broken in the future
-
-This binding uses the common clock binding[1]. It assumes a
-register-mapped multiplexer with multiple input clock signals or
-parents, one of which can be selected as output. This clock does not
-gate or adjust the parent rate via a divider or multiplier.
-
-By default the "clocks" property lists the parents in the same order
-as they are programmed into the regster. E.g:
-
- clocks = <&foo_clock>, <&bar_clock>, <&baz_clock>;
-
-results in programming the register as follows:
-
-register value selected parent clock
-0 foo_clock
-1 bar_clock
-2 baz_clock
-
-Some clock controller IPs do not allow a value of zero to be programmed
-into the register, instead indexing begins at 1. The optional property
-"index-starts-at-one" modified the scheme as follows:
-
-register value selected clock parent
-1 foo_clock
-2 bar_clock
-3 baz_clock
-
-The binding must provide the register to control the mux. Optionally
-the number of bits to shift the control field in the register can be
-supplied. If the shift value is missing it is the same as supplying
-a zero shift.
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt

-Required properties:
-- compatible : shall be "ti,mux-clock" or "ti,composite-mux-clock".
-- #clock-cells : from common clock binding; shall be set to 0.
-- clocks : link phandles of parent clocks
-- reg : register offset for register controlling adjustable mux
-
-Optional properties:
-- clock-output-names : from common clock binding.
-- ti,bit-shift : number of bits to shift the bit-mask, defaults to
- 0 if not present
-- ti,index-starts-at-one : valid input select programming starts at 1, not

-- ti,set-rate-parent : clk_set_rate is propagated to parent clock,

+ Some clocks in TI SoC support the autoidle feature. These properties are

+ mapped clock which can be put to idle automatically by hardware based on
+ usage and configuration bit setting. Autoidle clock is never an individual
+ clock, it is always a derivative of some basic clock like a gate, divider, or
+ fixed-factor.

+description: |
+ This clock It assumes a register-mapped adjustable clock rate divider
+ that does not gate and has only one input clock or parent. By default the
+ value programmed into the register is one less than the actual divisor value.
+ E.g:
+
+ register value actual divisor value
+ 0 1
+ 1 2
+ 2 3
+
+ This assumption may be modified by the following optional properties:
+
+ ti,index-starts-at-one - valid divisor values start at 1, not the default
+ of 0. E.g:
+ register value actual divisor value
+ 1 1
+ 2 2
+ 3 3
+
+ ti,index-power-of-two - valid divisor values are powers of two. E.g:
+ register value actual divisor value
+ 0 1
+ 1 2
+ 2 4
+
+ Additionally an array of valid dividers may be supplied like so:
+
+ ti,dividers = <4>, <8>, <0>, <16>;
+
+ Which will map the resulting values to a divisor table by their index:
+ register value actual divisor value
+ 0 4
+ 1 8
+ 2 <invalid divisor, skipped>
+ 3 16
+
+ Any zero value in this array means the corresponding bit-value is invalid
+ and must not be used.
+
+ The binding must also provide the register to control the divider and
+ unless the divider array is provided, min and max dividers. Optionally
+ the number of bits to shift that mask, if necessary. If the shift value
+ is missing it is the same as supplying a zero shift.
+
+ This binding can also optionally provide support to the hardware autoidle
+ feature.

-===========================================
-CPU topology binding description
-===========================================
-
-===========================================
-1 - Introduction
-===========================================
-
-In a SMP system, the hierarchy of CPUs is defined through three entities that
-are used to describe the layout of physical CPUs in the system:
-
-- socket
-- cluster
-- core
-- thread
-
-The bottom hierarchy level sits at core or thread level depending on whether
-symmetric multi-threading (SMT) is supported or not.
-
-For instance in a system where CPUs support SMT, "cpu" nodes represent all
-threads existing in the system and map to the hierarchy level "thread" above.
-In systems where SMT is not supported "cpu" nodes represent all cores present
-in the system and map to the hierarchy level "core" above.
-
-CPU topology bindings allow one to associate cpu nodes with hierarchical groups
-corresponding to the system hierarchy; syntactically they are defined as device
-tree nodes.
-
-Currently, only ARM/RISC-V intend to use this cpu topology binding but it may be
-used for any other architecture as well.
-
-The cpu nodes, as per bindings defined in [4], represent the devices that
-correspond to physical CPUs and are to be mapped to the hierarchy levels.
-
-A topology description containing phandles to cpu nodes that are not compliant
-with bindings standardized in [4] is therefore considered invalid.
-
-===========================================
-2 - cpu-map node
-===========================================
-
-The ARM/RISC-V CPU topology is defined within the cpu-map node, which is a direct
-child of the cpus node and provides a container where the actual topology
-nodes are listed.
-
-- cpu-map node
-
- Usage: Optional - On SMP systems provide CPUs topology to the OS.
- Uniprocessor systems do not require a topology
- description and therefore should not define a
- cpu-map node.
-
- Description: The cpu-map node is just a container node where its
- subnodes describe the CPU topology.
-
- Node name must be "cpu-map".
-
- The cpu-map node's parent node must be the cpus node.
-
- The cpu-map node's child nodes can be:
-
- - one or more cluster nodes or
- - one or more socket nodes in a multi-socket system
-
- Any other configuration is considered invalid.
-
-The cpu-map node can only contain 4 types of child nodes:
-
-- socket node
-- cluster node
-- core node
-- thread node
-
-whose bindings are described in paragraph 3.
-
-The nodes describing the CPU topology (socket/cluster/core/thread) can
-only be defined within the cpu-map node and every core/thread in the
-system must be defined within the topology. Any other configuration is
-invalid and therefore must be ignored.
-
-===========================================
-2.1 - cpu-map child nodes naming convention
-===========================================
-
-cpu-map child nodes must follow a naming convention where the node name
-must be "socketN", "clusterN", "coreN", "threadN" depending on the node type
-(ie socket/cluster/core/thread) (where N = {0, 1, ...} is the node number; nodes
-which are siblings within a single common parent node must be given a unique and
-sequential N value, starting from 0).
-cpu-map child nodes which do not share a common parent node can have the same
-name (ie same number N as other cpu-map child nodes at different device tree
-levels) since name uniqueness will be guaranteed by the device tree hierarchy.
-
-===========================================
-3 - socket/cluster/core/thread node bindings
-===========================================
-
-Bindings for socket/cluster/cpu/thread nodes are defined as follows:
-
-- socket node
-
- Description: must be declared within a cpu-map node, one node
- per physical socket in the system. A system can
- contain single or multiple physical socket.
- The association of sockets and NUMA nodes is beyond
- the scope of this bindings, please refer [2] for
- NUMA bindings.
-
- This node is optional for a single socket system.
-
- The socket node name must be "socketN" as described in 2.1 above.
- A socket node can not be a leaf node.
-
- A socket node's child nodes must be one or more cluster nodes.
-
- Any other configuration is considered invalid.
-
-- cluster node
-
- Description: must be declared within a cpu-map node, one node
- per cluster. A system can contain several layers of
- clustering within a single physical socket and cluster
- nodes can be contained in parent cluster nodes.
-
- The cluster node name must be "clusterN" as described in 2.1 above.
- A cluster node can not be a leaf node.
-
- A cluster node's child nodes must be:
-
- - one or more cluster nodes; or
- - one or more core nodes
-
- Any other configuration is considered invalid.
-
-- core node
-
- Description: must be declared in a cluster node, one node per core in
- the cluster. If the system does not support SMT, core
- nodes are leaf nodes, otherwise they become containers of
- thread nodes.
-
- The core node name must be "coreN" as described in 2.1 above.
-
- A core node must be a leaf node if SMT is not supported.
-
- Properties for core nodes that are leaf nodes:
-
- - cpu
- Usage: required
- Value type: <phandle>
- Definition: a phandle to the cpu node that corresponds to the
- core node.
-
- If a core node is not a leaf node (CPUs supporting SMT) a core node's
- child nodes can be:
-
- - one or more thread nodes
-
- Any other configuration is considered invalid.
-
-- thread node
-
- Description: must be declared in a core node, one node per thread
- in the core if the system supports SMT. Thread nodes are
- always leaf nodes in the device tree.
-
- The thread node name must be "threadN" as described in 2.1 above.
-
- A thread node must be a leaf node.
-
- A thread node must contain the following property:
-
- - cpu
- Usage: required
- Value type: <phandle>
- Definition: a phandle to the cpu node that corresponds to
- the thread node.

just supports idle_standby, an idle-states node is not required.
===========================================
- 6 - References

+ ===========================================
+
+ Idle states have different enter/exit latency and residency values.
+ The idle states supported by the QCOM SoC are defined as -
+
+ * Standby
+ * Retention
+ * Standalone Power Collapse (Standalone PC or SPC)
+ * Power Collapse (PC)
+
+ Standby: Standby does a little more in addition to architectural clock gating.
+ When the WFI instruction is executed the ARM core would gate its internal
+ clocks. In addition to gating the clocks, QCOM cpus use this instruction as a
+ trigger to execute the SPM state machine. The SPM state machine waits for the
+ interrupt to trigger the core back in to active. This triggers the cache
+ hierarchy to enter standby states, when all cpus are idle. An interrupt brings
+ the SPM state machine out of its wait, the next step is to ensure that the
+ cache hierarchy is also out of standby, and then the cpu is allowed to resume
+ execution. This state is defined as a generic ARM WFI state by the ARM cpuidle
+ driver and is not defined in the DT. The SPM state machine should be
+ configured to execute this state by default and after executing every other
+ state below.
+
+ Retention: Retention is a low power state where the core is clock gated and
+ the memory and the registers associated with the core are retained. The
+ voltage may be reduced to the minimum value needed to keep the processor
+ registers active. The SPM should be configured to execute the retention
+ sequence and would wait for interrupt, before restoring the cpu to execution
+ state. Retention may have a slightly higher latency than Standby.
+
+ Standalone PC: A cpu can power down and warmboot if there is a sufficient time
+ between the time it enters idle and the next known wake up. SPC mode is used
+ to indicate a core entering a power down state without consulting any other
+ cpu or the system resources. This helps save power only on that core. The SPM
+ sequence for this idle state is programmed to power down the supply to the
+ core, wait for the interrupt, restore power to the core, and ensure the
+ system state including cache hierarchy is ready before allowing core to
+ resume. Applying power and resetting the core causes the core to warmboot
+ back into Elevation Level (EL) which trampolines the control back to the
+ kernel. Entering a power down state for the cpu, needs to be done by trapping
+ into a EL. Failing to do so, would result in a crash enforced by the warm boot
+ code in the EL for the SoC. On SoCs with write-back L1 cache, the cache has to
+ be flushed in s/w, before powering down the core.
+
+ Power Collapse: This state is similar to the SPC mode, but distinguishes
+ itself in that the cpu acknowledges and permits the SoC to enter deeper sleep
+ modes. In a hierarchical power domain SoC, this means L2 and other caches can
+ be flushed, system bus, clocks - lowered, and SoC main XO clock gated and
+ voltages reduced, provided all cpus enter this state. Since the span of low
+ power modes possible at this state is vast, the exit latency and the residency
+ of this low power mode would be considered high even though at a cpu level,
+ this essentially is cpu power down. The SPM in this state also may handshake
+ with the Resource power manager (RPM) processor in the SoC to indicate a
+ complete application processor subsystem shut down.

+description: |
+ On newer Airoha SoC, CPU Frequency is scaled indirectly with SMC commands
+ to ATF.
+
+ A virtual clock is exposed. This virtual clock is a get-only clock and
+ is used to expose the current global CPU clock. The frequency info comes
+ by the output of the SMC command that reports the clock in MHz.
+
+ The SMC sets the CPU clock by providing an index, this is modelled as
+ performance states in a power domain.
+
+ CPUs can't be individually scaled as the CPU frequency is shared across
+ all CPUs and is global.

-Binding for MediaTek's CPUFreq driver
-=====================================
-
-Required properties:
-- clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock names.
-- clock-names: Should contain the following:
- "cpu" - The multiplexer for clock input of CPU cluster.
- "intermediate" - A parent of "cpu" clock which is used as "intermediate" clock
- source (usually MAINPLL) when the original CPU PLL is under
- transition and not stable yet.
- Please refer to Documentation/devicetree/bindings/clock/clock-bindings.txt for
- generic clock consumer properties.
-- operating-points-v2: Please refer to Documentation/devicetree/bindings/opp/opp-v2.yaml
- for detail.
-- proc-supply: Regulator for Vproc of CPU cluster.
-
-Optional properties:
-- sram-supply: Regulator for Vsram of CPU cluster. When present, the cpufreq driver
- needs to do "voltage tracking" to step by step scale up/down Vproc and
- Vsram to fit SoC specific needs. When absent, the voltage scaling
- flow is handled by hardware, hence no software "voltage tracking" is
- needed.
-- mediatek,cci:
- Used to confirm the link status between cpufreq and mediatek cci. Because
- cpufreq and mediatek cci could share the same regulator in some MediaTek SoCs.
- To prevent the issue of high frequency and low voltage, we need to use this
- property to make sure mediatek cci is ready.
- For details of mediatek cci, please refer to
- Documentation/devicetree/bindings/interconnect/mediatek,cci.yaml
-- #cooling-cells:
- For details, please refer to

-TI CPUFreq and OPP bindings
-================================
-
-Certain TI SoCs, like those in the am335x, am437x, am57xx, and dra7xx
-families support different OPPs depending on the silicon variant in use.
-The ti-cpufreq driver can use revision and an efuse value from the SoC to
-provide the OPP framework with supported hardware information. This is
-used to determine which OPPs from the operating-points-v2 table get enabled
-when it is parsed by the OPP framework.
-
-Required properties:
---------------------
-In 'cpus' nodes:
-- operating-points-v2: Phandle to the operating-points-v2 table to use.
-
-In 'operating-points-v2' table:
-- compatible: Should be
- - 'operating-points-v2-ti-cpu' for am335x, am43xx, and dra7xx/am57xx,
- omap34xx, omap36xx and am3517 SoCs
-- syscon: A phandle pointing to a syscon node representing the control module
- register space of the SoC.
-
-Optional properties:
---------------------
-- "vdd-supply", "vbb-supply": to define two regulators for dra7xx
-- "cpu0-supply", "vbb-supply": to define two regulators for omap36xx
-
-For each opp entry in 'operating-points-v2' table:
-- opp-supported-hw: Two bitfields indicating:
- 1. Which revision of the SoC the OPP is supported by
- 2. Which eFuse bits indicate this OPP is available
-
- A bitwise AND is performed against these values and if any bit
- matches, the OPP gets enabled.
-
-Example:
---------
-
-/* From arch/arm/boot/dts/am33xx.dtsi */
-cpus {
- #address-cells = <1>;
- #size-cells = <0>;
- cpu@0 {
- compatible = "arm,cortex-a8";

- clocks = <&dpll_mpu_ck>;
- clock-names = "cpu";
-
- clock-latency = <300000>; /* From omap-cpufreq driver */
- };
-};
-

- * cpu0 has different OPPs depending on SoC revision and some on revisions
- * 0x2 and 0x4 have eFuse bits that indicate if they are available or not
- */

+description: |
+ NOTE: the SEC 4 is also known as Freescale's Cryptographic Accelerator
+ Accelerator and Assurance Module (CAAM).
+
+ SEC 4 h/w can process requests from 2 types of sources.
+ 1. DPAA Queue Interface (HW interface between Queue Manager & SEC 4).
+ 2. Job Rings (HW interface between cores & SEC 4 registers).
+
+ High Speed Data Path Configuration:
+
+ HW interface between QM & SEC 4 and also BM & SEC 4, on DPAA-enabled parts
+ such as the P4080. The number of simultaneous dequeues the QI can make is
+ equal to the number of Descriptor Controller (DECO) engines in a particular
+ SEC version. E.g., the SEC 4.0 in the P4080 has 5 DECOs and can thus
+ dequeue from 5 subportals simultaneously.
+
+ Job Ring Data Path Configuration:
+
+ Each JR is located on a separate 4k page, they may (or may not) be made visible
+ in the memory partition devoted to a particular core. The P4080 has 4 JRs, so
+ up to 4 JRs can be configured; and all 4 JRs process requests in parallel.

-Overview
-
-DESCRIPTION
-
-SEC 4 h/w can process requests from 2 types of sources.
-1. DPAA Queue Interface (HW interface between Queue Manager & SEC 4).
-2. Job Rings (HW interface between cores & SEC 4 registers).
-
-High Speed Data Path Configuration:
-
-HW interface between QM & SEC 4 and also BM & SEC 4, on DPAA-enabled parts
-such as the P4080. The number of simultaneous dequeues the QI can make is
-equal to the number of Descriptor Controller (DECO) engines in a particular
-SEC version. E.g., the SEC 4.0 in the P4080 has 5 DECOs and can thus
-dequeue from 5 subportals simultaneously.
-
-Job Ring Data Path Configuration:
-
-Each JR is located on a separate 4k page, they may (or may not) be made visible
-in the memory partition devoted to a particular core. The P4080 has 4 JRs, so
-up to 4 JRs can be configured; and all 4 JRs process requests in parallel.
-
-=====================================================================

-
- - ranges
- Usage: required
- Value type: <prop-encoded-array>
- Definition: A standard property. Specifies the physical address
- range of the SEC 6.0 register space (-SNVS not included). A
- triplet that includes the child address, parent address, &
- length.
-
- Note: All other standard properties (see the Devicetree Specification)
- are allowed but are optional.
-
-EXAMPLE
- crypto@a0000 {
- compatible = "fsl,sec-v6.0";
- fsl,sec-era = <6>;
- #address-cells = <1>;
- #size-cells = <1>;
- reg = <0xa0000 0x20000>;
- ranges = <0 0xa0000 0x20000>;
- };
-
-=====================================================================
-Job Ring (JR) Node
-
- Child of the crypto node defines data processing interface to SEC 6
- across the peripheral bus for purposes of processing
- cryptographic descriptors. The specified address
- range can be made visible to one (or more) cores.
- The interrupt defined for this node is controlled within
- the address range of this node.
-
- - compatible
- Usage: required
- Value type: <string>
- Definition: Must include "fsl,sec-v6.0-job-ring".
-
- - reg
- Usage: required
- Value type: <prop-encoded-array>
- Definition: Specifies a two JR parameters: an offset from
- the parent physical address and the length the JR registers.
-
- - interrupts
- Usage: required
- Value type: <prop_encoded-array>
- Definition: Specifies the interrupts generated by this
- device. The value of the interrupts property
- consists of one interrupt specifier. The format
- of the specifier is defined by the binding document
- describing the node's interrupt parent.
-
-EXAMPLE
- jr@1000 {
- compatible = "fsl,sec-v6.0-job-ring";
- reg = <0x1000 0x1000>;
- interrupts = <49 2 0 0>;
- };
-
-===================================================================
-Full Example
-
-Since some chips may contain more than one SEC, the dtsi contains
-only the node contents, not the node itself. A chip using the SEC
-should include the dtsi inside each SEC node. Example:
-
-In qoriq-sec6.0.dtsi:
-
- compatible = "fsl,sec-v6.0";
- fsl,sec-era = <6>;
- #address-cells = <1>;
- #size-cells = <1>;
-
- jr@1000 {
- compatible = "fsl,sec-v6.0-job-ring",
- "fsl,sec-v5.2-job-ring",
- "fsl,sec-v5.0-job-ring",
- "fsl,sec-v4.4-job-ring",
- "fsl,sec-v4.0-job-ring";
- reg = <0x1000 0x1000>;
- };
-
- jr@2000 {
- compatible = "fsl,sec-v6.0-job-ring",
- "fsl,sec-v5.2-job-ring",
- "fsl,sec-v5.0-job-ring",
- "fsl,sec-v4.4-job-ring",
- "fsl,sec-v4.0-job-ring";
- reg = <0x2000 0x1000>;
- };
-
-In the C293 device tree, we add the include of public property:
-
- crypto@a0000 {
- /include/ "qoriq-sec6.0.dtsi"
- }
-
- crypto@a0000 {
- reg = <0xa0000 0x20000>;
- ranges = <0 0xa0000 0x20000>;
-
- jr@1000 {
- interrupts = <49 2 0 0>;
- };
-
- jr@2000 {
- interrupts = <50 2 0 0>;
- };
- };

-Device-Tree bindings for Atmel's HLCDC (High LCD Controller) DRM driver
-
-The Atmel HLCDC Display Controller is subdevice of the HLCDC MFD device.
-See ../../mfd/atmel-hlcdc.txt for more details.
-
-Required properties:
- - compatible: value should be "atmel,hlcdc-display-controller"
- - pinctrl-names: the pin control state names. Should contain "default".
- - pinctrl-0: should contain the default pinctrl states.
- - #address-cells: should be set to 1.
- - #size-cells: should be set to 0.
-
-Required children nodes:
- Children nodes are encoding available output ports and their connections
- to external devices using the OF graph reprensentation (see ../graph.txt).
- At least one port node is required.
-
-Optional properties in grandchild nodes:
- Any endpoint grandchild node may specify a desired video interface
- according to ../../media/video-interfaces.txt, specifically
- - bus-width: recognized values are <12>, <16>, <18> and <24>, and
- override any output mode selection heuristic, forcing "rgb444",
- "rgb565", "rgb666" and "rgb888" respectively.
-
-Example:
-
- hlcdc: hlcdc@f0030000 {
- compatible = "atmel,sama5d3-hlcdc";
- reg = <0xf0030000 0x2000>;
- interrupts = <36 IRQ_TYPE_LEVEL_HIGH 0>;
- clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>;
- clock-names = "periph_clk","sys_clk", "slow_clk";
-
- hlcdc-display-controller {
- compatible = "atmel,hlcdc-display-controller";
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb888>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- port@0 {
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0>;
-
- hlcdc_panel_output: endpoint@0 {
- reg = <0>;
- remote-endpoint = <&panel_input>;
- };
- };
- };
-
- hlcdc_pwm: hlcdc-pwm {
- compatible = "atmel,hlcdc-pwm";
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_lcd_pwm>;
- #pwm-cells = <3>;
- };
- };
-
-Example 2: With a video interface override to force rgb565; as above
-but with these changes/additions:
-
- &hlcdc {
- hlcdc-display-controller {
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb565>;
-
- port@0 {
- hlcdc_panel_output: endpoint@0 {
- bus-width = <16>;
- };
- };
- };
- };

+maintainers:

+
+description: |
+ The IT6263 is a high-performance single-chip De-SSC(De-Spread Spectrum) LVDS
+ to HDMI converter. Combined with LVDS receiver and HDMI 1.4a transmitter,
+ the IT6263 supports LVDS input and HDMI 1.4 output by conversion function.
+ The built-in LVDS receiver can support single-link and dual-link LVDS inputs,
+ and the built-in HDMI transmitter is fully compliant with HDMI 1.4a/3D, HDCP
+ 1.2 and backward compatible with DVI 1.0 specification.
+
+ The IT6263 also encodes and transmits up to 8 channels of I2S digital audio,
+ with sampling rate up to 192KHz and sample size up to 24 bits. In addition,
+ an S/PDIF input port takes in compressed audio of up to 192KHz frame rate.
+
+ The newly supported High-Bit Rate(HBR) audio by HDMI specifications v1.3 is
+ provided by the IT6263 in two interfaces: the four I2S input ports or the
+ S/PDIF input port. With both interfaces the highest possible HBR frame rate
+ is supported at up to 768KHz.

+
+ Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output
+
+ Each bridge has a dedicated flash containing firmware for supporting the custom

+
+ The hardware do not provide control over the video processing pipeline, as the

-Drivers for the second video output of the GE B850v3:
- STDP4028-ge-b850v3-fw bridges (LVDS-DP)
- STDP2690-ge-b850v3-fw bridges (DP-DP++)
-
-The video processing pipeline on the second output on the GE B850v3:
-
- Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output
-
-Each bridge has a dedicated flash containing firmware for supporting the custom
-design. The result is that, in this design, neither the STDP4028 nor the
-STDP2690 behave as the stock bridges would. The compatible strings include the
-suffix "-ge-b850v3-fw" to make it clear that the driver is for the bridges with
-the firmware specific for the GE B850v3.
-
-The hardware do not provide control over the video processing pipeline, as the
-two bridges behaves as a single one. The only interfaces exposed by the
-hardware are EDID, HPD, and interrupts.
-

- - compatible : "megachips,stdp4028-ge-b850v3-fw"

+
+description: |
+ A blit operation (block based image transfer) reads up to 3 source images
+ from memory and computes one destination image from it, which is written
+ back to memory. The following basic operations are supported:
+
+ * Buffer Fill
+ Fills a buffer with constant color
+
+ * Buffer Copy
+ Copies one source to a destination buffer.
+
+ * Image Blend
+ Combines two source images by a blending equation and writes result to
+ destination (which can be one of the sources).
+
+ * Image Rop2/3
+ Combines up to three source images by a logical equation (raster operation)
+ and writes result to destination (which can be one of the sources).
+
+ * Image Flip
+ Mirrors the source image in horizontal and/or vertical direction.
+
+ * Format Convert
+ Convert between the supported color and buffer formats.
+
+ * Color Transform
+ Modify colors by linear or non-linear transformations.
+
+ * Image Scale
+ Changes size of the source image.
+
+ * Image Rotate
+ Rotates the source image by any angle.
+
+ * Image Filter
+ Performs an FIR filter operation on the source image.
+
+ * Image Warp
+ Performs a re-sampling of the source image with any pattern. The sample
+ point positions are read from a compressed coordinate buffer.
+
+ * Buffer Pack
+ Writes an image with color components stored in up to three different
+ buffers (planar formats) into a single buffer (packed format).
+
+ * Chroma Resample
+ Converts between different YUV formats that differ in chroma sampling rate
+ (4:4:4, 4:2:2, 4:2:0).

+
+description: |
+ The Command Sequencer is designed to autonomously process command lists.
+ By that it can load setups into the DC configuration and synchronize to
+ hardware events. This releases a system's CPU from workload, because it
+ does not need to wait for certain events. Also it simplifies SW architecture,
+ because no interrupt handlers are required. Setups are read via AXI bus,
+ while write access to configuration registers occurs directly via an internal
+ bus. This saves bandwidth for the AXI interconnect and improves the system
+ architecture in terms of safety aspects.

+
+description: |
+ The unit can increase the physical color resolution of a display from 5, 6, 7
+ or 8 bits per RGB channel to a virtual resolution of 10 bits. The physical
+ resolution can be set individually for each channel.
+
+ The resolution is increased by mixing the two physical colors that are nearest
+ to the virtual color code in a variable ratio either by time (temporal
+ dithering) or by position (spatial dithering).
+
+ An optimized algorithm for temporal dithering minimizes noise artifacts on the
+ output image.
+
+ The dither operation can be individually enabled or disabled for each pixel
+ using the alpha input bit.

+description: |
+ The unit can change the dimension of the input frame by nearest or linear
+ re-sampling with 1/32 sub pixel precision.
+
+ Internally it consist of two independent blocks for horizontal and vertical
+ scaling. The sequence of both operations is arbitrary.
+
+ Any frame dimensions between 1 and 16384 pixels in width and height are
+ supported, except that the vertical scaler has a frame width maximum
+ depending of the system's functional limitations.
+
+ In general all scale factors are supported inside the supported frame
+ dimensions. In range of scale factors 1/16..16 the filtered output colors
+ are LSBit precise (e.g. DC ripple free).

+
+description: |
+ The Store unit is the interface between the internal pixel processing
+ pipeline, which is 30-bit RGB plus 8-bit Alpha, and the AXI bus for
+ destination buffer access. It is used for the destination of Blit Engines.
+ It comprises a set of built-in functions to generate a wide range of buffer
+ formats. Note, that these are exactly inverse to corresponding functions in
+ the Fetch Unit.

-Device-Tree bindings for LVDS Display Bridge (ldb)
-
-LVDS Display Bridge
-===================
-
-The LVDS Display Bridge device tree node contains up to two lvds-channel
-nodes describing each of the two LVDS encoder channels of the bridge.
-
-Required properties:
- - #address-cells : should be <1>
- - #size-cells : should be <0>
- - compatible : should be "fsl,imx53-ldb" or "fsl,imx6q-ldb".
- Both LDB versions are similar, but i.MX6 has an additional
- multiplexer in the front to select any of the four IPU display
- interfaces as input for each LVDS channel.
- - gpr : should be <&gpr> on i.MX53 and i.MX6q.
- The phandle points to the iomuxc-gpr region containing the LVDS
- control register.
-- clocks, clock-names : phandles to the LDB divider and selector clocks and to
- the display interface selector clocks, as described in
- Documentation/devicetree/bindings/clock/clock-bindings.txt
- The following clocks are expected on i.MX53:
- "di0_pll" - LDB LVDS channel 0 mux
- "di1_pll" - LDB LVDS channel 1 mux
- "di0" - LDB LVDS channel 0 gate
- "di1" - LDB LVDS channel 1 gate
- "di0_sel" - IPU1 DI0 mux
- "di1_sel" - IPU1 DI1 mux
- On i.MX6q the following additional clocks are needed:
- "di2_sel" - IPU2 DI0 mux
- "di3_sel" - IPU2 DI1 mux
- The needed clock numbers for each are documented in
- Documentation/devicetree/bindings/clock/imx5-clock.yaml, and in
- Documentation/devicetree/bindings/clock/imx6q-clock.yaml.
-
-Optional properties:
- - pinctrl-names : should be "default" on i.MX53, not used on i.MX6q
- - pinctrl-0 : a phandle pointing to LVDS pin settings on i.MX53,
- not used on i.MX6q
- - fsl,dual-channel : boolean. if it exists, only LVDS channel 0 should
- be configured - one input will be distributed on both outputs in dual
- channel mode
-
-LVDS Channel
-============
-
-Each LVDS Channel has to contain either an of graph link to a panel device node
-or a display-timings node that describes the video timings for the connected
-LVDS display as well as the fsl,data-mapping and fsl,data-width properties.
-
-Required properties:
- - reg : should be <0> or <1>
- - port: Input and output port nodes with endpoint definitions as defined in
- Documentation/devicetree/bindings/graph.txt.
- On i.MX5, the internal two-input-multiplexer is used. Due to hardware
- limitations, only one input port (port@[0,1]) can be used for each channel
- (lvds-channel@[0,1], respectively).
- On i.MX6, there should be four input ports (port@[0-3]) that correspond
- to the four LVDS multiplexer inputs.
- A single output port (port@2 on i.MX5, port@4 on i.MX6) must be connected
- to a panel input port. Optionally, the output port can be left out if
- display-timings are used instead.
-
-Optional properties (required if display-timings are used):
- - ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
- - display-timings : A node that describes the display timings as defined in
- Documentation/devicetree/bindings/display/panel/display-timing.txt.
- - fsl,data-mapping : should be "spwg" or "jeida"
- This describes how the color bits are laid out in the
- serialized LVDS signal.
- - fsl,data-width : should be <18> or <24>
-
-example:
-
-gpr: iomuxc-gpr@53fa8000 {
- /* ... */
-};
-
-ldb: ldb@53fa8008 {
- #address-cells = <1>;

+description:
+ ETHDR (ET High Dynamic Range) is a MediaTek internal HDR engine and is
+ designed for HDR video and graphics conversion in the external display path.
+ It handles multiple HDR input types and performs tone mapping, color
+ space/color format conversion, and then combine different layers,
+ output the required HDR or SDR signal to the subsequent display path.
+ This engine is composed of two video frontends, two graphic frontends,
+ one video backend and a mixer. ETHDR has two DMA function blocks, DS and ADL.
+ These two function blocks read the pre-programmed registers from DRAM and
+ set them to HW in the v-blanking period.

+description: |
+ This panel requires a dual-channel DSI host to operate. It supports two modes:
+ - left-right: each channel drives the left or right half of the screen
+ - even-odd: each channel drives the even or odd lines of the screen
+
+ Each of the DSI channels controls a separate DSI peripheral. The peripheral
+ driven by the first link (DSI-LINK1) is considered the primary peripheral
+ and controls the device. The 'link2' property contains a phandle to the
+ peripheral driven by the second link (DSI-LINK2).

+description: |
+ This binding file is a collection of eDP panels from before the generic
+ "edp-panel" compatible was introduced. It is kept around to support old
+ dts files. The only reason one might add a new panel here instead of using
+ the generic "edp-panel" is if it needed to be used on an eDP controller
+ that doesn't support the generic "edp-panel" compatible, but it should be
+ a strong preference to add the generic "edp-panel" compatible instead.

+ This panel requires a dual-channel DSI host to operate and it supports
+ only left-right split mode, where each channel drives the left or right
+ half of the screen and only video mode.
+
+ Each of the DSI channels controls a separate DSI peripheral.
+ The peripheral driven by the first link (DSI-LINK1), left one, is
+ considered the primary peripheral and controls the device.

+description: |
+ The STMicroelectronics STM32 LVDS Display Interface Transmitter handles the
+ LVDS protocol: it maps the pixels received from the upstream Pixel-DMA (LTDC)
+ onto the LVDS PHY.
+
+ It is composed of three sub blocks:
+ - LVDS host: handles the LVDS protocol (FPD / OpenLDI) and maps its input
+ pixels onto the data lanes of the PHY
+ - LVDS PHY: parallelize the data and drives the LVDS data lanes
+ - LVDS wrapper: handles top-level settings
+
+ The LVDS controller driver supports the following high-level features:
+ - FDP-Link-I and OpenLDI (v0.95) protocols
+ - Single-Link or Dual-Link operation
+ - Single-Display or Double-Display (with the same content duplicated on both)
+ - Flexible Bit-Mapping, including JEIDA and VESA
+ - RGB888 or RGB666 output
+ - Synchronous design, with one input pixel per clock cycle

- - adi,source-bus-width,
- adi,destination-bus-width: Width of the source or destination bus in bits.
- - adi,source-bus-type,
- adi,destination-bus-type: Type of the source or destination bus. Must be one
- of the following:
- 0 (AXI_DMAC_TYPE_AXI_MM): Memory mapped AXI interface
- 1 (AXI_DMAC_TYPE_AXI_STREAM): Streaming AXI interface
- 2 (AXI_DMAC_TYPE_AXI_FIFO): FIFO interface
-
-Deprecated optional channel properties:
- - adi,length-width: Width of the DMA transfer length register.
- - adi,cyclic: Must be set if the channel supports hardware cyclic DMA
- transfers.
- - adi,2d: Must be set if the channel supports hardware 2D DMA transfers.
-
-DMA clients connected to the AXI-DMAC DMA controller must use the format

-Applied Micro X-Gene SoC DMA nodes
-
-DMA nodes are defined to describe on-chip DMA interfaces in
-APM X-Gene SoC.
-
-Required properties for DMA interfaces:
-- compatible: Should be "apm,xgene-dma".
-- device_type: set to "dma".
-- reg: Address and length of the register set for the device.
- It contains the information of registers in the following order:
- 1st - DMA control and status register address space.
- 2nd - Descriptor ring control and status register address space.
- 3rd - Descriptor ring command register address space.
- 4th - Soc efuse register address space.
-- interrupts: DMA has 5 interrupts sources. 1st interrupt is
- DMA error reporting interrupt. 2nd, 3rd, 4th and 5th interrupts
- are completion interrupts for each DMA channels.
-- clocks: Reference to the clock entry.
-

-* Freescale Direct Memory Access (DMA) Controller for i.MX
-
-This document will only describe differences to the generic DMA Controller and
-DMA request bindings as described in dma/dma.txt .
-
-* DMA controller
-
-Required properties:
-- compatible : Should be "fsl,<chip>-dma". chip can be imx1, imx21 or imx27
-- reg : Should contain DMA registers location and length
-- interrupts : First item should be DMA interrupt, second one is optional and
- should contain DMA Error interrupt
-- #dma-cells : Has to be 1. imx-dma does not support anything else.
-
-Optional properties:
-- dma-channels : Number of DMA channels supported. Should be 16.
-- #dma-channels : deprecated
-- dma-requests : Number of DMA requests supported.
-- #dma-requests : deprecated
-
-Example:
-
- dma: dma@10001000 {
- compatible = "fsl,imx27-dma";
- reg = <0x10001000 0x1000>;
- interrupts = <32 33>;
- #dma-cells = <1>;
- dma-channels = <16>;
- };
-
-
-* DMA client
-
-Clients have to specify the DMA requests with phandles in a list.
-
-Required properties:
-- dmas: List of one or more DMA request specifiers. One DMA request specifier
- consists of a phandle to the DMA controller followed by the integer
- specifying the request line.
-- dma-names: List of string identifiers for the DMA requests. For the correct
- names, have a look at the specific client driver.
-
-Example:
-
- sdhci1: sdhci@10013000 {
- ...
- dmas = <&dma 7>;
- dma-names = "rx-tx";
- ...
- };

- "fsl,ls1043a-qdma": for ls1043A Board
- "fsl,ls1046a-qdma": for ls1046A Board
-- reg: Should contain the register's base address and length.
-- interrupts: Should contain a reference to the interrupt used by this
- device.
-- interrupt-names: Should contain interrupt names:
- "qdma-queue0": the block0 interrupt
- "qdma-queue1": the block1 interrupt
- "qdma-queue2": the block2 interrupt
- "qdma-queue3": the block3 interrupt
- "qdma-error": the error interrupt

-This device follows the generic DMA bindings defined in dma/dma.txt.
-
-Required properties:
-
-- compatible: Must be one of
- "mediatek,mt7622-hsdma": for MT7622 SoC
- "mediatek,mt7623-hsdma": for MT7623 SoC
-- reg: Should contain the register's base address and length.
-- interrupts: Should contain a reference to the interrupt used by this
- device.
-- clocks: Should be the clock specifiers corresponding to the entry in
- clock-names property.
-- clock-names: Should contain "hsdma" entries.
-- power-domains: Phandle to the power domain that the device is part of
-- #dma-cells: The length of the DMA specifier, must be <1>. This one cell
- in dmas property of a client device represents the channel
- number.
-Example:
-
- hsdma: dma-controller@1b007000 {

-* NVIDIA Tegra APB DMA controller
-
-Required properties:
-- compatible: Should be "nvidia,<chip>-apbdma"
-- reg: Should contain DMA registers location and length. This shuld include
- all of the per-channel registers.
-- interrupts: Should contain all of the per-channel DMA interrupts.
-- clocks: Must contain one entry, for the module clock.
- See ../clocks/clock-bindings.txt for details.
-- resets : Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names : Must include the following entries:
- - dma
-- #dma-cells : Must be <1>. This dictates the length of DMA specifiers in
- client nodes' dmas properties. The specifier represents the DMA request
- select value for the peripheral. For more details, consult the Tegra TRM's
- documentation of the APB DMA channel control register REQ_SEL field.

-Qualcomm Technologies HIDMA Management interface
-
-Qualcomm Technologies HIDMA is a high speed DMA device. It only supports
-memcpy and memset capabilities. It has been designed for virtualized
-environments.
-
-Each HIDMA HW instance consists of multiple DMA channels. These channels
-share the same bandwidth. The bandwidth utilization can be partitioned
-among channels based on the priority and weight assignments.
-
-There are only two priority levels and 15 weigh assignments possible.
-
-Other parameters here determine how much of the system bus this HIDMA
-instance can use like maximum read/write request and number of bytes to
-read/write in a single burst.
-
-Main node required properties:
-- compatible: "qcom,hidma-mgmt-1.0";
-- reg: Address range for DMA device
-- dma-channels: Number of channels supported by this DMA controller.
-- max-write-burst-bytes: Maximum write burst in bytes that HIDMA can
- occupy the bus for in a single transaction. A memcpy requested is
- fragmented to multiples of this amount. This parameter is used while
- writing into destination memory. Setting this value incorrectly can
- starve other peripherals in the system.
-- max-read-burst-bytes: Maximum read burst in bytes that HIDMA can
- occupy the bus for in a single transaction. A memcpy request is
- fragmented to multiples of this amount. This parameter is used while
- reading the source memory. Setting this value incorrectly can starve
- other peripherals in the system.
-- max-write-transactions: This value is how many times a write burst is
- applied back to back while writing to the destination before yielding
- the bus.
-- max-read-transactions: This value is how many times a read burst is
- applied back to back while reading the source before yielding the bus.
-- channel-reset-timeout-cycles: Channel reset timeout in cycles for this SOC.
- Once a reset is applied to the HW, HW starts a timer for reset operation
- to confirm. If reset is not completed within this time, HW reports reset
- failure.
-
-Sub-nodes:
-
-HIDMA has one or more DMA channels that are used to move data from one
-memory location to another.
-
-When the OS is not in control of the management interface (i.e. it's a guest),
-the channel nodes appear on their own, not under a management node.
-
-Required properties:
-- compatible: must contain "qcom,hidma-1.0" for initial HW or
- "qcom,hidma-1.1"/"qcom,hidma-1.2" for MSI capable HW.
-- reg: Addresses for the transfer and event channel
-- interrupts: Should contain the event interrupt
-- desc-count: Number of asynchronous requests this channel can handle
-- iommus: required a iommu node
-
-Optional properties for MSI:
-- msi-parent : See the generic MSI binding described in
- devicetree/bindings/interrupt-controller/msi.txt for a description of the
- msi-parent property.
-
-Example:
-
-Hypervisor OS configuration:
-
- hidma-mgmt@f9984000 = {
- compatible = "qcom,hidma-mgmt-1.0";
- reg = <0xf9984000 0x15000>;

+=====================================
+Devicetree Sources (DTS) Coding Style
+=====================================
+
+When writing Devicetree Sources (DTS) please observe below guidelines. They
+should be considered complementary to any rules expressed already in
+the Devicetree Specification and the dtc compiler (including W=1 and W=2
+builds).
+
+Individual architectures and subarchitectures can define additional rules,
+making the coding style stricter.
+
+Naming and Valid Characters
+---------------------------
+
+The Devicetree Specification allows a broad range of characters in node
+and property names, but this coding style narrows the range down to achieve
+better code readability.
+
+1. Node and property names can use only the following characters:
+
+ * Lowercase characters: [a-z]
+ * Digits: [0-9]
+ * Dash: -
+
+2. Labels can use only the following characters:
+
+ * Lowercase characters: [a-z]
+ * Digits: [0-9]
+ * Underscore: _
+
+3. Unless a bus defines differently, unit addresses shall use lowercase
+ hexadecimal digits, without leading zeros (padding).
+
+4. Hex values in properties, e.g. "reg", shall use lowercase hex. The address
+ part can be padded with leading zeros.
+
+Example::
+
+ gpi_dma2: dma-controller@a00000 {
+ compatible = "qcom,sm8550-gpi-dma", "qcom,sm6350-gpi-dma";
+ reg = <0x0 0x00a00000 0x0 0x60000>;
+ }
+
+Order of Nodes
+--------------
+
+1. Nodes on any bus, thus using unit addresses for children, shall be
+ ordered by unit address in ascending order.
+ Alternatively for some subarchitectures, nodes of the same type can be
+ grouped together, e.g. all I2C controllers one after another even if this
+ breaks unit address ordering.
+
+2. Nodes without unit addresses shall be ordered alpha-numerically by the node
+ name. For a few node types, they can be ordered by the main property, e.g.
+ pin configuration states ordered by value of "pins" property.
+
+3. When extending nodes in the board DTS via &label, the entries shall be
+ ordered either alpha-numerically or by keeping the order from DTSI, where
+ the choice depends on the subarchitecture.
+
+The above-described ordering rules are easy to enforce during review, reduce
+chances of conflicts for simultaneous additions of new nodes to a file and help
+in navigating through the DTS source.
+
+Example::
+
+ /* SoC DTSI */
+
+ / {
+ cpus {
+ /* ... */
+ };
+
+ psci {
+ /* ... */
+ };
+
+ soc@0 {
+ dma: dma-controller@10000 {
+ /* ... */
+ };
+
+ clk: clock-controller@80000 {
+ /* ... */
+ };
+ };
+ };
+
+ /* Board DTS - alphabetical order */
+
+ &clk {
+ /* ... */
+ };
+
+ &dma {
+ /* ... */
+ };
+
+ /* Board DTS - alternative order, keep as DTSI */
+
+ &dma {
+ /* ... */
+ };
+
+ &clk {
+ /* ... */
+ };
+
+Order of Properties in Device Node
+----------------------------------
+
+The following order of properties in device nodes is preferred:
+
+1. "compatible"
+2. "reg"
+3. "ranges"
+4. Standard/common properties (defined by common bindings, e.g. without
+ vendor-prefixes)
+5. Vendor-specific properties
+6. "status" (if applicable), preceded by a blank line if there is content
+ before the property
+7. Child nodes, where each node is preceded with a blank line
+
+The "status" property is by default "okay", thus it can be omitted.
+
+The above-described ordering follows this approach:
+
+1. Most important properties start the node: compatible then bus addressing to
+ match unit address.
+2. Each node will have common properties in similar place.
+3. Status is the last information to annotate that device node is or is not
+ finished (board resources are needed).
+
+The individual properties inside each group shall use natural sort order by
+the property name.
+
+Example::
+
+ /* SoC DTSI */
+
+ device_node: device-class@6789abc {
+ compatible = "vendor,device";
+ reg = <0x0 0x06789abc 0x0 0xa123>;
+ ranges = <0x0 0x0 0x06789abc 0x1000>;
+ #dma-cells = <1>;
+ clocks = <&clock_controller 0>, <&clock_controller 1>;
+ clock-names = "bus", "host";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ vendor,custom-property = <2>;
+
+ status = "disabled";
+
+ child_node: child-class@100 {
+ reg = <0x100 0x200>;
+ /* ... */
+ };
+ };
+
+ /* Board DTS */
+
+ &device_node {
+ vdd-0v9-supply = <&board_vreg1>;
+ vdd-1v8-supply = <&board_vreg4>;
+ vdd-3v3-supply = <&board_vreg2>;
+ vdd-12v-supply = <&board_vreg3>;
+
+ status = "okay";
+ }
+
+Indentation and wrapping
+------------------------
+
+1. Use indentation and wrap lines according to
+ Documentation/process/coding-style.rst.
+2. Each entry in arrays with multiple cells, e.g. "reg" with two IO addresses,
+ shall be enclosed in <>.
+3. For arrays spanning across lines, it is preferred to split on item boundary
+ and align the continued entries with opening < from the first line.
+ Usually avoid splitting individual items unless they significantly exceed
+ line wrap limit.
+
+Example::
+
+ thermal-sensor@c271000 {
+ compatible = "qcom,sm8550-tsens", "qcom,tsens-v2";
+ reg = <0x0 0x0c271000 0x0 0x1000>,
+ <0x0 0x0c222000 0x0 0x1000>;
+ /* Lines exceeding coding style line wrap limit: */
+ interconnects = <&aggre1_noc MASTER_USB3_0 0 &mc_virt SLAVE_EBI1 0>,
+ <&gem_noc MASTER_APPSS_PROC 0 &config_noc SLAVE_USB3_0 0>;
+ };
+
+Organizing DTSI and DTS
+-----------------------
+
+The DTSI and DTS files shall be organized in a way representing the common,
+reusable parts of hardware. Typically, this means organizing DTSI and DTS files
+into several files:
+
+1. DTSI with contents of the entire SoC, without nodes for hardware not present
+ on the SoC.
+2. If applicable: DTSI with common or re-usable parts of the hardware, e.g.
+ entire System-on-Module.
+3. DTS representing the board.
+
+Hardware components that are present on the board shall be placed in the
+board DTS, not in the SoC or SoM DTSI. A partial exception is a common
+external reference SoC input clock, which could be coded as a fixed-clock in
+the SoC DTSI with its frequency provided by each board DTS.

-Stratix10 SoCFPGA ECC Manager (ARM64)
-The Stratix10 SoC ECC Manager handles the IRQs for each peripheral
-in a shared register similar to the Arria10. However, Stratix10 ECC
-requires access to registers that can only be read from Secure Monitor
-with SMC calls. Therefore the device tree is slightly different. Note
-that only 1 interrupt is sent in Stratix10 because the double bit errors
-are treated as SErrors in ARM64 instead of IRQs in ARM32.
-
-Required Properties:
-- compatible : Should be "altr,socfpga-s10-ecc-manager"
-- altr,sysgr-syscon : phandle to Stratix10 System Manager Block
- containing the ECC manager registers.
-- interrupts : Should be single bit error interrupt.
-- interrupt-controller : boolean indicator that ECC Manager is an interrupt controller
-- #interrupt-cells : must be set to 2.
-- #address-cells: must be 1
-- #size-cells: must be 1
-- ranges : standard definition, should translate from local addresses
-
-Subcomponents:
-
-SDRAM ECC
-Required Properties:
-- compatible : Should be "altr,sdram-edac-s10"
-- interrupts : Should be single bit error interrupt.
-
-On-Chip RAM ECC
-Required Properties:

-- reg : Address and size for ECC block registers.
-- altr,ecc-parent : phandle to parent OCRAM node.
-- interrupts : Should be single bit error interrupt.
-
-Ethernet FIFO ECC
-Required Properties:
-- compatible : Should be "altr,socfpga-s10-eth-mac-ecc"
-- reg : Address and size for ECC block registers.
-- altr,ecc-parent : phandle to parent Ethernet node.
-- interrupts : Should be single bit error interrupt.
-

-Required Properties:
-- compatible : Should be "altr,socfpga-s10-usb-ecc"
-- reg : Address and size for ECC block registers.
-- altr,ecc-parent : phandle to parent USB node.
-- interrupts : Should be single bit error interrupt.
-
-SDMMC FIFO ECC
-Required Properties:
-- compatible : Should be "altr,socfpga-s10-sdmmc-ecc"
-- reg : Address and size for ECC block registers.

+description:
+ Different from other Qualcomm Snapdragon sc8180x and sc8280xp-based
+ machines, the Huawei Matebook E Go tablets use embedded controllers
+ while others use a system called PMIC GLink which handles battery,
+ UCSI, USB Type-C DP Alt Mode. In addition, Huawei's implementation
+ also handles additional features, such as charging thresholds, FN
+ lock, smart charging, tablet lid status, thermal sensors, and more.

-The Richtek RT8973A is Micro USB Switch with OVP and I2C interface. The RT8973A
-is a USB port accessory detector and switch that is optimized to protect low
-voltage system from abnormal high input voltage (up to 28V) and supports high
-speed USB operation. Also, RT8973A support 'auto-configuration' mode.
-If auto-configuration mode is enabled, RT8973A would control internal h/w patch
-for USB D-/D+ switching.
-
-Required properties:
-- compatible: Should be "richtek,rt8973a-muic"
-- reg: Specifies the I2C slave address of the MUIC block. It should be 0x14
-- interrupts: Interrupt specifiers for detection interrupt sources.

-Intel Service Layer Driver for Stratix10 SoC
-============================================
-Intel Stratix10 SoC is composed of a 64 bit quad-core ARM Cortex A53 hard
-processor system (HPS) and Secure Device Manager (SDM). When the FPGA is
-configured from HPS, there needs to be a way for HPS to notify SDM the
-location and size of the configuration data. Then SDM will get the
-configuration data from that location and perform the FPGA configuration.
-
-To meet the whole system security needs and support virtual machine requesting
-communication with SDM, only the secure world of software (EL3, Exception
-Layer 3) can interface with SDM. All software entities running on other
-exception layers must channel through the EL3 software whenever it needs
-service from SDM.
-
-Intel Stratix10 service layer driver, running at privileged exception level
-(EL1, Exception Layer 1), interfaces with the service providers and provides
-the services for FPGA configuration, QSPI, Crypto and warm reset. Service layer
-driver also manages secure monitor call (SMC) to communicate with secure monitor
-code running in EL3.
-
-Required properties:
--------------------
-The svc node has the following mandatory properties, must be located under
-the firmware node.
-
-- compatible: "intel,stratix10-svc" or "intel,agilex-svc"
-- method: smc or hvc
- smc - Secure Monitor Call
- hvc - Hypervisor Call
-- memory-region:
- phandle to the reserved memory node. See
- Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt
- for details
-
-Example:
--------
-
- reserved-memory {
- #address-cells = <2>;
- #size-cells = <2>;
- ranges;
-
- service_reserved: svcbuffer@0 {
- compatible = "shared-dma-pool";
- reg = <0x0 0x0 0x0 0x1000000>;
- alignment = <0x1000>;
- no-map;
- };
- };
-
- firmware {
- svc {
- compatible = "intel,stratix10-svc";
- method = "smc";
- memory-region = <&service_reserved>;

+title: T-HEAD TH1520 AON (Always-On) Firmware
+
+description: |
+ The Always-On (AON) subsystem in the TH1520 SoC is responsible for managing
+ low-power states, system wakeup events, and power management tasks. It is
+ designed to operate independently in a dedicated power domain, allowing it to
+ remain functional even during the SoC's deep sleep states.
+
+ At the heart of the AON subsystem is the E902, a low-power core that executes
+ firmware responsible for coordinating tasks such as power domain control,
+ clock management, and system wakeup signaling. Communication between the main
+ SoC and the AON subsystem is handled through a mailbox interface, which
+ enables message-based interactions with the AON firmware.

-Introduction
-============
-
-FPGA Regions represent FPGA's and partial reconfiguration regions of FPGA's in
-the Device Tree. FPGA Regions provide a way to program FPGAs under device tree
-control.
-
-This device tree binding document hits some of the high points of FPGA usage and
-attempts to include terminology used by both major FPGA manufacturers. This
-document isn't a replacement for any manufacturers specifications for FPGA
-usage.
-
-
-Terminology
-===========
-
-Full Reconfiguration
- * The entire FPGA is programmed.
-
-Partial Reconfiguration (PR)
- * A section of an FPGA is reprogrammed while the rest of the FPGA is not
- affected.
- * Not all FPGA's support PR.
-
-Partial Reconfiguration Region (PRR)
- * Also called a "reconfigurable partition"
- * A PRR is a specific section of an FPGA reserved for reconfiguration.
- * A base (or static) FPGA image may create a set of PRR's that later may
- be independently reprogrammed many times.
- * The size and specific location of each PRR is fixed.
- * The connections at the edge of each PRR are fixed. The image that is loaded
- into a PRR must fit and must use a subset of the region's connections.
- * The busses within the FPGA are split such that each region gets its own
- branch that may be gated independently.
-
-Persona
- * Also called a "partial bit stream"
- * An FPGA image that is designed to be loaded into a PRR. There may be
- any number of personas designed to fit into a PRR, but only one at at time
- may be loaded.
- * A persona may create more regions.
-
-FPGA Bridge
- * FPGA Bridges gate bus signals between a host and FPGA.
- * FPGA Bridges should be disabled while the FPGA is being programmed to
- prevent spurious signals on the cpu bus and to the soft logic.
- * FPGA bridges may be actual hardware or soft logic on an FPGA.
- * During Full Reconfiguration, hardware bridges between the host and FPGA
- will be disabled.
- * During Partial Reconfiguration of a specific region, that region's bridge
- will be used to gate the busses. Traffic to other regions is not affected.
- * In some implementations, the FPGA Manager transparantly handles gating the
- buses, eliminating the need to show the hardware FPGA bridges in the
- device tree.
- * An FPGA image may create a set of reprogrammable regions, each having its
- own bridge and its own split of the busses in the FPGA.
-
-FPGA Manager
- * An FPGA Manager is a hardware block that programs an FPGA under the control
- of a host processor.
-
-Base Image
- * Also called the "static image"
- * An FPGA image that is designed to do full reconfiguration of the FPGA.
- * A base image may set up a set of partial reconfiguration regions that may
- later be reprogrammed.

-Figure 1: An FPGA set up with a base image that created three regions. Each
-region (PRR0-2) gets its own split of the busses that is independently gated by
-a soft logic bridge (Bridge0-2) in the FPGA. The contents of each PRR can be
-reprogrammed independently while the rest of the system continues to function.
-
-
-Sequence
-========
-
-When a DT overlay that targets an FPGA Region is applied, the FPGA Region will
-do the following:
-
- 1. Disable appropriate FPGA bridges.
- 2. Program the FPGA using the FPGA manager.
- 3. Enable the FPGA bridges.
- 4. The Device Tree overlay is accepted into the live tree.
- 5. Child devices are populated.
-
-When the overlay is removed, the child nodes will be removed and the FPGA Region
-will disable the bridges.
-
-
-FPGA Region
-===========
-
-FPGA Regions represent FPGA's and FPGA PR regions in the device tree. An FPGA
-Region brings together the elements needed to program on a running system and
-add the child devices:
-
- * FPGA Manager
- * FPGA Bridges
- * image-specific information needed to to the programming.
- * child nodes
-
-The intended use is that a Device Tree overlay (DTO) can be used to reprogram an
-FPGA while an operating system is running.
-
-An FPGA Region that exists in the live Device Tree reflects the current state.
-If the live tree shows a "firmware-name" property or child nodes under an FPGA
-Region, the FPGA already has been programmed. A DTO that targets an FPGA Region
-and adds the "firmware-name" property is taken as a request to reprogram the
-FPGA. After reprogramming is successful, the overlay is accepted into the live
-tree.
-
-The base FPGA Region in the device tree represents the FPGA and supports full
-reconfiguration. It must include a phandle to an FPGA Manager. The base
-FPGA region will be the child of one of the hardware bridges (the bridge that
-allows register access) between the cpu and the FPGA. If there are more than
-one bridge to control during FPGA programming, the region will also contain a
-list of phandles to the additional hardware FPGA Bridges.
-
-For partial reconfiguration (PR), each PR region will have an FPGA Region.
-These FPGA regions are children of FPGA bridges which are then children of the
-base FPGA region. The "Full Reconfiguration to add PRR's" example below shows
-this.
-
-If an FPGA Region does not specify an FPGA Manager, it will inherit the FPGA
-Manager specified by its ancestor FPGA Region. This supports both the case
-where the same FPGA Manager is used for all of an FPGA as well the case where
-a different FPGA Manager is used for each region.
-
-FPGA Regions do not inherit their ancestor FPGA regions' bridges. This prevents
-shutting down bridges that are upstream from the other active regions while one
-region is getting reconfigured (see Figure 1 above). During PR, the FPGA's
-hardware bridges remain enabled. The PR regions' bridges will be FPGA bridges
-within the static image of the FPGA.
-
-Required properties:
-- compatible : should contain "fpga-region"
-- fpga-mgr : should contain a phandle to an FPGA Manager. Child FPGA Regions
- inherit this property from their ancestor regions. An fpga-mgr property
- in a region will override any inherited FPGA manager.
-- #address-cells, #size-cells, ranges : must be present to handle address space
- mapping for child nodes.
-
-Optional properties:
-- firmware-name : should contain the name of an FPGA image file located on the
- firmware search path. If this property shows up in a live device tree
- it indicates that the FPGA has already been programmed with this image.
- If this property is in an overlay targeting an FPGA region, it is a
- request to program the FPGA with that image.
-- fpga-bridges : should contain a list of phandles to FPGA Bridges that must be
- controlled during FPGA programming along with the parent FPGA bridge.
- This property is optional if the FPGA Manager handles the bridges.
- If the fpga-region is the child of an fpga-bridge, the list should not
- contain the parent bridge.
-- partial-fpga-config : boolean, set if partial reconfiguration is to be done,
- otherwise full reconfiguration is done.
-- external-fpga-config : boolean, set if the FPGA has already been configured
- prior to OS boot up.
-- encrypted-fpga-config : boolean, set if the bitstream is encrypted
-- region-unfreeze-timeout-us : The maximum time in microseconds to wait for
- bridges to successfully become enabled after the region has been
- programmed.
-- region-freeze-timeout-us : The maximum time in microseconds to wait for
- bridges to successfully become disabled before the region has been
- programmed.
-- config-complete-timeout-us : The maximum time in microseconds time for the
- FPGA to go to operating mode after the region has been programmed.
-- child nodes : devices in the FPGA after programming.
-
-In the example below, when an overlay is applied targeting fpga-region0,
-fpga_mgr is used to program the FPGA. Two bridges are controlled during
-programming: the parent fpga_bridge0 and fpga_bridge1. Because the region is
-the child of fpga_bridge0, only fpga_bridge1 needs to be specified in the
-fpga-bridges property. During programming, these bridges are disabled, the
-firmware specified in the overlay is loaded to the FPGA using the FPGA manager
-specified in the region. If FPGA programming succeeds, the bridges are
-reenabled and the overlay makes it into the live device tree. The child devices
-are then populated. If FPGA programming fails, the bridges are left disabled
-and the overlay is rejected. The overlay's ranges property maps the lwhps
-bridge's region (0xff200000) and the hps bridge's region (0xc0000000) for use by
-the two child devices.

-Supported Use Models
-====================
-
-In all cases the live DT must have the FPGA Manager, FPGA Bridges (if any), and
-a FPGA Region. The target of the Device Tree Overlay is the FPGA Region. Some
-uses are specific to an FPGA device.
-
- * No FPGA Bridges
- In this case, the FPGA Manager which programs the FPGA also handles the
- bridges behind the scenes. No FPGA Bridge devices are needed for full
- reconfiguration.
-
- * Full reconfiguration with hardware bridges
- In this case, there are hardware bridges between the processor and FPGA that
- need to be controlled during full reconfiguration. Before the overlay is
- applied, the live DT must include the FPGA Manager, FPGA Bridges, and a
- FPGA Region. The FPGA Region is the child of the bridge that allows
- register access to the FPGA. Additional bridges may be listed in a
- fpga-bridges property in the FPGA region or in the device tree overlay.
-
- * Partial reconfiguration with bridges in the FPGA
- In this case, the FPGA will have one or more PRR's that may be programmed
- separately while the rest of the FPGA can remain active. To manage this,
- bridges need to exist in the FPGA that can gate the buses going to each FPGA
- region while the buses are enabled for other sections. Before any partial
- reconfiguration can be done, a base FPGA image must be loaded which includes
- PRR's with FPGA bridges. The device tree should have an FPGA region for each
- PRR.
-
-Device Tree Examples
-====================
-
-The intention of this section is to give some simple examples, focusing on
-the placement of the elements detailed above, especially:
- * FPGA Manager
- * FPGA Bridges
- * FPGA Region
- * ranges
- * target-path or target
-
-For the purposes of this section, I'm dividing the Device Tree into two parts,
-each with its own requirements. The two parts are:
- * The live DT prior to the overlay being added
- * The DT overlay
-
-The live Device Tree must contain an FPGA Region, an FPGA Manager, and any FPGA
-Bridges. The FPGA Region's "fpga-mgr" property specifies the manager by phandle
-to handle programming the FPGA. If the FPGA Region is the child of another FPGA
-Region, the parent's FPGA Manager is used. If FPGA Bridges need to be involved,
-they are specified in the FPGA Region by the "fpga-bridges" property. During
-FPGA programming, the FPGA Region will disable the bridges that are in its
-"fpga-bridges" list and will re-enable them after FPGA programming has
-succeeded.
-
-The Device Tree Overlay will contain:
- * "target-path" or "target"
- The insertion point where the contents of the overlay will go into the
- live tree. target-path is a full path, while target is a phandle.
- * "ranges"
- The address space mapping from processor to FPGA bus(ses).
- * "firmware-name"
- Specifies the name of the FPGA image file on the firmware search
- path. The search path is described in the firmware class documentation.
- * "partial-fpga-config"
- This binding is a boolean and should be present if partial reconfiguration
- is to be done.
- * child nodes corresponding to hardware that will be loaded in this region of
- the FPGA.
-
-Device Tree Example: Full Reconfiguration without Bridges
-=========================================================
-
-Live Device Tree contains:
- fpga_mgr0: fpga-mgr@f8007000 {
- compatible = "xlnx,zynq-devcfg-1.0";
- reg = <0xf8007000 0x100>;
- interrupt-parent = <&intc>;
- interrupts = <0 8 4>;
- clocks = <&clkc 12>;
- clock-names = "ref_clk";
- syscon = <&slcr>;
- };
-
- fpga_region0: fpga-region0 {
- compatible = "fpga-region";
- fpga-mgr = <&fpga_mgr0>;
- #address-cells = <0x1>;
- #size-cells = <0x1>;
- ranges;
- };
-
-DT Overlay contains:
-
-/dts-v1/;
-/plugin/;
-
-&fpga_region0 {
- #address-cells = <1>;
- #size-cells = <1>;
-
- firmware-name = "zynq-gpio.bin";
-
- gpio1: gpio@40000000 {
- compatible = "xlnx,xps-gpio-1.00.a";

- gpio-controller;
- #gpio-cells = <0x2>;
- xlnx,gpio-width= <0x6>;
- };
-};
-
-Device Tree Example: Full Reconfiguration to add PRR's
-======================================================
-
-The base FPGA Region is specified similar to the first example above.
-
-This example programs the FPGA to have two regions that can later be partially
-configured. Each region has its own bridge in the FPGA fabric.
-
-DT Overlay contains:
-
-/dts-v1/;
-/plugin/;
-
-&fpga_region0 {
- #address-cells = <1>;
- #size-cells = <1>;
-
- firmware-name = "base.rbf";
-
- fpga-bridge@4400 {
- compatible = "altr,freeze-bridge-controller";
- reg = <0x4400 0x10>;
-
- fpga_region1: fpga-region1 {
- compatible = "fpga-region";
- #address-cells = <0x1>;
- #size-cells = <0x1>;
- ranges;
- };
- };
-
- fpga-bridge@4420 {
- compatible = "altr,freeze-bridge-controller";
- reg = <0x4420 0x10>;
-
- fpga_region2: fpga-region2 {
- compatible = "fpga-region";
- #address-cells = <0x1>;
- #size-cells = <0x1>;
- ranges;
- };
- };
-};
-
-Device Tree Example: Partial Reconfiguration
-============================================
-
-This example reprograms one of the PRR's set up in the previous example.
-
-The sequence that occurs when this overlay is similar to the above, the only
-differences are that the FPGA is partially reconfigured due to the
-"partial-fpga-config" boolean and the only bridge that is controlled during
-programming is the FPGA based bridge of fpga_region1.
-
-/dts-v1/;
-/plugin/;
-
-&fpga_region1 {
- #address-cells = <1>;
- #size-cells = <1>;
-
- firmware-name = "soc_image2.rbf";
- partial-fpga-config;
-
- gpio@10040 {

- clocks = <0x2>;
- altr,ngpio = <0x4>;

-};
-
-Constraints
-===========
-
-It is beyond the scope of this document to fully describe all the FPGA design
-constraints required to make partial reconfiguration work[1] [2] [3], but a few
-deserve quick mention.
-
-A persona must have boundary connections that line up with those of the partion
-or region it is designed to go into.
-
-During programming, transactions through those connections must be stopped and
-the connections must be held at a fixed logic level. This can be achieved by
-FPGA Bridges that exist on the FPGA fabric prior to the partial reconfiguration.

+ Introduction
+ ============
+
+ FPGA Regions represent FPGA's and partial reconfiguration regions of FPGA's in
+ the Device Tree. FPGA Regions provide a way to program FPGAs under device tree
+ control.
+
+ The documentation hits some of the high points of FPGA usage and
+ attempts to include terminology used by both major FPGA manufacturers. This
+ document isn't a replacement for any manufacturers specifications for FPGA
+ usage.
+
+ Terminology
+ ===========
+
+ Full Reconfiguration
+ * The entire FPGA is programmed.
+
+ Partial Reconfiguration (PR)
+ * A section of an FPGA is reprogrammed while the rest of the FPGA is not
+ affected.
+ * Not all FPGA's support PR.
+
+ Partial Reconfiguration Region (PRR)
+ * Also called a "reconfigurable partition"
+ * A PRR is a specific section of an FPGA reserved for reconfiguration.
+ * A base (or static) FPGA image may create a set of PRR's that later may
+ be independently reprogrammed many times.
+ * The size and specific location of each PRR is fixed.
+ * The connections at the edge of each PRR are fixed. The image that is loaded
+ into a PRR must fit and must use a subset of the region's connections.
+ * The busses within the FPGA are split such that each region gets its own
+ branch that may be gated independently.
+
+ Persona
+ * Also called a "partial bit stream"
+ * An FPGA image that is designed to be loaded into a PRR. There may be
+ any number of personas designed to fit into a PRR, but only one at a time
+ may be loaded.
+ * A persona may create more regions.
+
+ FPGA Bridge
+ * FPGA Bridges gate bus signals between a host and FPGA.
+ * FPGA Bridges should be disabled while the FPGA is being programmed to
+ prevent spurious signals on the cpu bus and to the soft logic.
+ * FPGA bridges may be actual hardware or soft logic on an FPGA.
+ * During Full Reconfiguration, hardware bridges between the host and FPGA
+ will be disabled.
+ * During Partial Reconfiguration of a specific region, that region's bridge
+ will be used to gate the busses. Traffic to other regions is not affected.
+ * In some implementations, the FPGA Manager transparently handles gating the
+ buses, eliminating the need to show the hardware FPGA bridges in the
+ device tree.
+ * An FPGA image may create a set of reprogrammable regions, each having its
+ own bridge and its own split of the busses in the FPGA.
+
+ FPGA Manager
+ * An FPGA Manager is a hardware block that programs an FPGA under the control
+ of a host processor.
+
+ Base Image
+ * Also called the "static image"
+ * An FPGA image that is designed to do full reconfiguration of the FPGA.
+ * A base image may set up a set of partial reconfiguration regions that may
+ later be reprogrammed.

+ Figure 1: An FPGA set up with a base image that created three regions. Each
+ region (PRR0-2) gets its own split of the busses that is independently gated by
+ a soft logic bridge (Bridge0-2) in the FPGA. The contents of each PRR can be
+ reprogrammed independently while the rest of the system continues to function.
+
+ Sequence
+ ========
+
+ When a DT overlay that targets an FPGA Region is applied, the FPGA Region will
+ do the following:
+
+ 1. Disable appropriate FPGA bridges.
+ 2. Program the FPGA using the FPGA manager.
+ 3. Enable the FPGA bridges.
+ 4. The Device Tree overlay is accepted into the live tree.
+ 5. Child devices are populated.
+
+ When the overlay is removed, the child nodes will be removed and the FPGA Region
+ will disable the bridges.
+
+ FPGA Region
+ ===========
+
+ FPGA Regions represent FPGA's and FPGA PR regions in the device tree. An FPGA
+ Region brings together the elements needed to program on a running system and
+ add the child devices:
+
+ * FPGA Manager
+ * FPGA Bridges
+ * image-specific information needed to the programming.
+ * child nodes
+
+ The intended use is that a Device Tree overlay (DTO) can be used to reprogram an
+ FPGA while an operating system is running.
+
+ An FPGA Region that exists in the live Device Tree reflects the current state.
+ If the live tree shows a "firmware-name" property or child nodes under an FPGA
+ Region, the FPGA already has been programmed. A DTO that targets an FPGA Region
+ and adds the "firmware-name" property is taken as a request to reprogram the
+ FPGA. After reprogramming is successful, the overlay is accepted into the live
+ tree.
+
+ The base FPGA Region in the device tree represents the FPGA and supports full
+ reconfiguration. It must include a phandle to an FPGA Manager. The base
+ FPGA region will be the child of one of the hardware bridges (the bridge that
+ allows register access) between the cpu and the FPGA. If there are more than
+ one bridge to control during FPGA programming, the region will also contain a
+ list of phandles to the additional hardware FPGA Bridges.
+
+ For partial reconfiguration (PR), each PR region will have an FPGA Region.
+ These FPGA regions are children of FPGA bridges which are then children of the
+ base FPGA region. The "Full Reconfiguration to add PRR's" example below shows
+ this.
+
+ If an FPGA Region does not specify an FPGA Manager, it will inherit the FPGA
+ Manager specified by its ancestor FPGA Region. This supports both the case
+ where the same FPGA Manager is used for all of an FPGA as well the case where
+ a different FPGA Manager is used for each region.
+
+ FPGA Regions do not inherit their ancestor FPGA regions' bridges. This prevents
+ shutting down bridges that are upstream from the other active regions while one
+ region is getting reconfigured (see Figure 1 above). During PR, the FPGA's
+ hardware bridges remain enabled. The PR regions' bridges will be FPGA bridges
+ within the static image of the FPGA.
+
+ Supported Use Models

-GPIO controllers on MPC8xxx SoCs
-
-This is for the non-QE/CPM/GUTs GPIO controllers as found on
-8349, 8572, 8610 and compatible.
-
-Every GPIO controller node must have #gpio-cells property defined,
-this information will be used to translate gpio-specifiers.
-See bindings/gpio/gpio.txt for details of how to specify GPIO
-information for devices.
-
-The GPIO module usually is connected to the SoC's internal interrupt
-controller, see bindings/interrupt-controller/interrupts.txt (the
-interrupt client nodes section) for details how to specify this GPIO
-module's interrupt.
-
-The GPIO module may serve as another interrupt controller (cascaded to
-the SoC's internal interrupt controller). See the interrupt controller
-nodes section in bindings/interrupt-controller/interrupts.txt for
-details.
-
-Required properties:
-- compatible: "fsl,<chip>-gpio" followed by "fsl,mpc8349-gpio"
- for 83xx, "fsl,mpc8572-gpio" for 85xx, or
- "fsl,mpc8610-gpio" for 86xx.
-- #gpio-cells: Should be two. The first cell is the pin number
- and the second cell is used to specify optional
- parameters (currently unused).
-- interrupts: Interrupt mapping for GPIO IRQ.
-- gpio-controller: Marks the port as GPIO controller.
-
-Optional properties:
-- interrupt-controller: Empty boolean property which marks the GPIO
- module as an IRQ controller.
-- #interrupt-cells: Should be two. Defines the number of integer
- cells required to specify an interrupt within
- this interrupt controller. The first cell
- defines the pin number, the second cell
- defines additional flags (trigger type,
- trigger polarity). Note that the available
- set of trigger conditions supported by the
- GPIO module depends on the actual SoC.
-
-Example of gpio-controller nodes for a MPC8347 SoC:
-
- gpio1: gpio-controller@c00 {
- #gpio-cells = <2>;
- compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
- reg = <0xc00 0x100>;
- interrupt-parent = <&ipic>;
- interrupts = <74 0x8>;
- gpio-controller;
- interrupt-controller;
- #interrupt-cells = <2>;
- };
-
- gpio2: gpio-controller@d00 {
- #gpio-cells = <2>;
- compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
- reg = <0xd00 0x100>;
- interrupt-parent = <&ipic>;
- interrupts = <75 0x8>;
- gpio-controller;
- };
-
-Example of a peripheral using the GPIO module as an IRQ controller:
-
- funkyfpga@0 {
- compatible = "funky-fpga";
- ...
- interrupt-parent = <&gpio1>;
- interrupts = <4 3>;
- };

-Broadcom Kona Family GPIO
-=========================
-
-This GPIO driver is used in the following Broadcom SoCs:
- BCM11130, BCM11140, BCM11351, BCM28145, BCM28155
-
-The Broadcom GPIO Controller IP can be configured prior to synthesis to
-support up to 8 banks of 32 GPIOs where each bank has its own IRQ. The
-GPIO controller only supports edge, not level, triggering of interrupts.
-
-Required properties
--------------------
-
-- compatible: "brcm,bcm11351-gpio", "brcm,kona-gpio"
-- reg: Physical base address and length of the controller's registers.
-- interrupts: The interrupt outputs from the controller. There is one GPIO
- interrupt per GPIO bank. The number of interrupts listed depends on the
- number of GPIO banks on the SoC. The interrupts must be ordered by bank,
- starting with bank 0. There is always a 1:1 mapping between banks and
- IRQs.
-- #gpio-cells: Should be <2>. The first cell is the pin number, the second
- cell is used to specify optional parameters:
- - bit 0 specifies polarity (0 for normal, 1 for inverted)
- See also "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.
-- #interrupt-cells: Should be <2>. The first cell is the GPIO number. The
- second cell is used to specify flags. The following subset of flags is
- supported:
- - trigger type (bits[1:0]):
- 1 = low-to-high edge triggered.
- 2 = high-to-low edge triggered.
- 3 = low-to-high or high-to-low edge triggered
- Valid values are 1, 2, 3
- See also .../devicetree/bindings/interrupt-controller/interrupts.txt.
-- gpio-controller: Marks the device node as a GPIO controller.
-- interrupt-controller: Marks the device node as an interrupt controller.
-
-Example:
- gpio: gpio@35003000 {
- compatible = "brcm,bcm11351-gpio", "brcm,kona-gpio";
- reg = <0x35003000 0x800>;
- interrupts =
- <GIC_SPI 106 IRQ_TYPE_LEVEL_HIGH
- GIC_SPI 115 IRQ_TYPE_LEVEL_HIGH
- GIC_SPI 114 IRQ_TYPE_LEVEL_HIGH
- GIC_SPI 113 IRQ_TYPE_LEVEL_HIGH

-Keystone 2 DSP GPIO controller bindings
-
-HOST OS userland running on ARM can send interrupts to DSP cores using
-the DSP GPIO controller IP. It provides 28 IRQ signals per each DSP core.
-This is one of the component used by the IPC mechanism used on Keystone SOCs.
-
-For example TCI6638K2K SoC has 8 DSP GPIO controllers:
- - 8 for C66x CorePacx CPUs 0-7
-
-Keystone 2 DSP GPIO controller has specific features:
-- each GPIO can be configured only as output pin;
-- setting GPIO value to 1 causes IRQ generation on target DSP core;
-- reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still
- pending.
-
-Required Properties:
-- compatible: should be "ti,keystone-dsp-gpio"
-- ti,syscon-dev: phandle/offset pair. The phandle to syscon used to
- access device state control registers and the offset of device's specific
- registers within device state control registers range.
-- gpio-controller: Marks the device node as a gpio controller.
-- #gpio-cells: Should be 2.
-
-Please refer to gpio.txt in this directory for details of the common GPIO
-bindings used by client devices.

-* IBM/AMCC/APM GPIO Controller for PowerPC 4XX series and compatible SoCs
-
-All GPIOs are pin-shared with other functions. DCRs control whether a
-particular pin that has GPIO capabilities acts as a GPIO or is used for
-another purpose. GPIO outputs are separately programmable to emulate
-an open-drain driver.
-
-Required properties:
- - compatible: must be "ibm,ppc4xx-gpio"
- - reg: address and length of the register set for the device
- - #gpio-cells: must be set to 2. The first cell is the pin number
- and the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low
- - gpio-controller: marks the device node as a gpio controller.
-
-Example:
-
-GPIO0: gpio@ef600b00 {
- compatible = "ibm,ppc4xx-gpio";
- reg = <0xef600b00 0x00000048>;
- #gpio-cells = <2>;
- gpio-controller;

+ This SGPIO controller is for NUVOTON NPCM7xx and NPCM8xx SoC and detailed
+ information is in the NPCM7XX/8XX SERIAL I/O EXPANSION INTERFACE section.
+ Nuvoton NPCM7xx SGPIO module is combines a serial to parallel IC (HC595)
+ and a parallel to serial IC (HC165).
+ Clock is a division of the APB3 clock.
+ This interface has 4 pins (D_out , D_in, S_CLK, LDSH).
+ NPCM7xx/NPCM8xx have two sgpio modules. Each module can support up
+ to 64 output pins, and up to 64 input pins, the pin is only for GPI or GPO.
+ GPIO pins can be programmed to support the following options
+ - Support interrupt option for each input port and various interrupt
+ sensitivity options (level-high, level-low, edge-high, edge-low)
+ - ngpios is number of nuvoton,input-ngpios GPIO lines and nuvoton,output-ngpios GPIO lines.
+ nuvoton,input-ngpios GPIO lines is only for GPI.
+ nuvoton,output-ngpios GPIO lines is only for GPO.

-Raspberry Pi GPIO expander
-
-The Raspberry Pi 3 GPIO expander is controlled by the VC4 firmware. The
-firmware exposes a mailbox interface that allows the ARM core to control the
-GPIO lines on the expander.
-
-The Raspberry Pi GPIO expander node must be a child node of the Raspberry Pi
-firmware node.
-
-Required properties:
-
-- compatible : Should be "raspberrypi,firmware-gpio"
-- gpio-controller : Marks the device node as a gpio controller
-- #gpio-cells : Should be two. The first cell is the pin number, and
- the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low

- mboxes = <&mailbox>;
-
- expgpio: gpio {

-=== ST Microelectronics SPEAr SPI CS Driver ===
-
-SPEAr platform provides a provision to control chipselects of ARM PL022 Prime
-Cell spi controller through its system registers, which otherwise remains under
-PL022 control. If chipselect remain under PL022 control then they would be
-released as soon as transfer is over and TxFIFO becomes empty. This is not
-desired by some of the device protocols above spi which expect (multiple)
-transfers without releasing their chipselects.
-
-Chipselects can be controlled by software by turning them as GPIOs. SPEAr
-provides another interface through system registers through which software can
-directly control each PL022 chipselect. Hence, it is natural for SPEAr to export
-the control of this interface as gpio.
-
-Required properties:
-
- * compatible: should be defined as "st,spear-spics-gpio"
- * reg: mentioning address range of spics controller
- * st-spics,peripcfg-reg: peripheral configuration register offset
- * st-spics,sw-enable-bit: bit offset to enable sw control
- * st-spics,cs-value-bit: bit offset to drive chipselect low or high
- * st-spics,cs-enable-mask: chip select number bit mask
- * st-spics,cs-enable-shift: chip select number program offset
- * gpio-controller: Marks the device node as gpio controller
- * #gpio-cells: should be 1 and will mention chip select number
-
-All the above bit offsets are within peripcfg register.
-
-Example:
--------
-spics: spics@e0700000{
- compatible = "st,spear-spics-gpio";
- reg = <0xe0700000 0x1000>;
- st-spics,peripcfg-reg = <0x3b0>;
- st-spics,sw-enable-bit = <12>;
- st-spics,cs-value-bit = <11>;
- st-spics,cs-enable-mask = <3>;
- st-spics,cs-enable-shift = <8>;
- gpio-controller;
- #gpio-cells = <2>;

- cs-gpios = <&gpio1 7 0>, <&spics 0>,

+ HOST OS userland running on ARM can send interrupts to DSP cores using

+ This is one of the component used by the IPC mechanism used on Keystone SOCs.
+
+ For example TCI6638K2K SoC has 8 DSP GPIO controllers:
+ - 8 for C66x CorePacx CPUs 0-7
+
+ Keystone 2 DSP GPIO controller has specific features:
+ - each GPIO can be configured only as output pin;
+ - setting GPIO value to 1 causes IRQ generation on target DSP core;
+ - reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still
+ pending.

-Bindings for the Western Digital's MyBook Live memory-mapped GPIO controllers.
-
-The Western Digital MyBook Live has two memory-mapped GPIO controllers.
-Both GPIO controller only have a single 8-bit data register, where GPIO
-state can be read and/or written.
-
-Required properties:
- - compatible: should be "wd,mbl-gpio"
- - reg-names: must contain
- "dat" - data register
- - reg: address + size pairs describing the GPIO register sets;
- order must correspond with the order of entries in reg-names
- - #gpio-cells: must be set to 2. The first cell is the pin number and
- the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low
- - gpio-controller: Marks the device node as a gpio controller.
-
-Optional properties:
- - no-output: GPIOs are read-only.
-
-Examples:
- gpio0: gpio0@e0000000 {
- compatible = "wd,mbl-gpio";
- reg-names = "dat";
- reg = <0xe0000000 0x1>;

- Currently recognized values:
- - nvidia,gk20a
- - nvidia,gm20b
- - nvidia,gp10b
- - nvidia,gv11b
-- reg: Physical base address and length of the controller's registers.
- Must contain two entries:
- - first entry for bar0
- - second entry for bar1
-- interrupts: Must contain an entry for each entry in interrupt-names.
- See ../interrupt-controller/interrupts.txt for details.
-- interrupt-names: Must include the following entries:
- - stall
- - nonstall
-- vdd-supply: regulator for supply voltage. Only required for GPUs not using
- power domains.
-- clocks: Must contain an entry for each entry in clock-names.
- See ../clocks/clock-bindings.txt for details.
-- clock-names: Must include the following entries:
- - gpu
- - pwr
-If the compatible string is "nvidia,gm20b", then the following clock
-is also required:
- - ref
-If the compatible string is "nvidia,gv11b", then the following clock is also
-required:
- - fuse
-- resets: Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names: Must include the following entries:
- - gpu
-- power-domains: GPUs that make use of power domains can define this property
- instead of vdd-supply. Currently "nvidia,gp10b" makes use of this.

-SPRD Hardware Spinlock Device Binding
--------------------------------------

-Required properties :
-- compatible : should be "sprd,hwspinlock-r3p0".
-- reg : the register address of hwspinlock.
-- #hwlock-cells : hwlock users only use the hwlock id to represent a specific
- hwlock, so the number of cells should be <1> here.
-- clock-names : Must contain "enable".
-- clocks : Must contain a phandle entry for the clock in clock-names, see the
- common clock bindings.
-
-Please look at the generic hwlock binding for usage information for consumers,

- - reg: I2C address
-
- Optional properties:
- - ti,single-shot: This chip has two power modes: single-shot (chip takes one
- measurement and then shuts itself down) and continuous (
- chip takes continuous measurements). The continuous mode is
- more reliable and suitable for hardware monitor type device,
- but the single-shot mode is more power-friendly and useful
- for battery-powered device which cares power consumptions
- while still needs some measurements occasionally.
- If this property is present, the single-shot mode will be
- used, instead of the default continuous one for monitoring.

- = The node contains optional child nodes for three channels =
- = Each child node describes the information of input source =

- 12000000 uV.
-- maxim,fan-prescale : Pre-scaling value, as per datasheet [1]. Lower values
- allow more fine-grained control of slower fans.
- Valid: 1, 2, 4, 8, 16.
-- maxim,fan-target-rpm: Initial requested fan rotation speed. If specified, the
- driver selects closed-loop mode and the requested speed.
- This ensures the fan is already running before userspace
- takes over.

-
-Optional properties:

-- interrupts : This contains an interrupt specifier for each fan
- tachometer output connected to an interrupt source.
- The output signal must generate a defined number of

+ summation control function. This function adds the single
+ shunt-voltage conversions for the desired channels in order to
+ compare the combined sum to the programmed limit. The Shunt-Voltage
+ Sum Limit register contains the programmed value that is compared
+ to the value in the Shunt-Voltage Sum register in order to
+ determine if the total summed limit is exceeded. If the
+ shunt-voltage sum limit value is exceeded, the critical alert pin
+ is asserted.
+
+ For the summation limit to have a meaningful value, it is necessary
+ to use the same shunt-resistor value on all enabled channels. If
+ this is not the case or if a channel should not be used for
+ triggering the critical alert pin, then this property can be used
+ exclude specific channels from the summation control function.

-GPIO-based I2C Arbitration Using a Challenge & Response Mechanism
-=================================================================
-This uses GPIO lines and a challenge & response mechanism to arbitrate who is
-the master of an I2C bus in a multimaster situation.
-
-In many cases using GPIOs to arbitrate is not needed and a design can use
-the standard I2C multi-master rules. Using GPIOs is generally useful in
-the case where there is a device on the bus that has errata and/or bugs
-that makes standard multimaster mode not feasible.
-
-Note that this scheme works well enough but has some downsides:
-* It is nonstandard (not using standard I2C multimaster)
-* Having two masters on a bus in general makes it relatively hard to debug
- problems (hard to tell if i2c issues were caused by one master, another, or
- some device on the bus).
-
-
-Algorithm:
-
-All masters on the bus have a 'bus claim' line which is an output that the
-others can see. These are all active low with pull-ups enabled. We'll
-describe these lines as:
-
-- OUR_CLAIM: output from us signaling to other hosts that we want the bus
-- THEIR_CLAIMS: output from others signaling that they want the bus
-
-The basic algorithm is to assert your line when you want the bus, then make
-sure that the other side doesn't want it also. A detailed explanation is best
-done with an example.
-
-Let's say we want to claim the bus. We:
-1. Assert OUR_CLAIM.
-2. Waits a little bit for the other sides to notice (slew time, say 10
- microseconds).
-3. Check THEIR_CLAIMS. If none are asserted then the we have the bus and we are
- done.
-4. Otherwise, wait for a few milliseconds and see if THEIR_CLAIMS are released.
-5. If not, back off, release the claim and wait for a few more milliseconds.
-6. Go back to 1 (until retry time has expired).
-
-
-Required properties:
-- compatible: i2c-arb-gpio-challenge
-- our-claim-gpio: The GPIO that we use to claim the bus.
-- their-claim-gpios: The GPIOs that the other sides use to claim the bus.
- Note that some implementations may only support a single other master.
-- I2C arbitration bus node. See i2c-arb.txt in this directory.
-
-Optional properties:
-- slew-delay-us: microseconds to wait for a GPIO to go high. Default is 10 us.
-- wait-retry-us: we'll attempt another claim after this many microseconds.
- Default is 3000 us.
-- wait-free-us: we'll give up after this many microseconds. Default is 50000 us.
-
-
-Example:
- i2c@12ca0000 {
- compatible = "acme,some-i2c-device";
- #address-cells = <1>;
- #size-cells = <0>;
- };
-
- i2c-arbitrator {
- compatible = "i2c-arb-gpio-challenge";
-
- i2c-parent = <&{/i2c@12CA0000}>;
-
- our-claim-gpio = <&gpf0 3 1>;
- their-claim-gpios = <&gpe0 4 1>;
- slew-delay-us = <10>;
- wait-retry-us = <3000>;
- wait-free-us = <50000>;
-
- i2c-arb {
- #address-cells = <1>;
- #size-cells = <0>;
-
- i2c@52 {
- // Normal I2C device

-Generic device tree bindings for I2C busses
-===========================================
-
-This document describes generic bindings which can be used to describe I2C
-busses and their child devices in a device tree.
-
-Required properties (per bus)
------------------------------
-
-- #address-cells - should be <1>. Read more about addresses below.
-- #size-cells - should be <0>.
-- compatible - name of I2C bus controller
-
-For other required properties e.g. to describe register sets,
-clocks, etc. check the binding documentation of the specific driver.
-
-The cells properties above define that an address of children of an I2C bus
-are described by a single value.
-
-Optional properties (per bus)
------------------------------
-
-These properties may not be supported by all drivers. However, if a driver
-wants to support one of the below features, it should adapt these bindings.
-
-- clock-frequency
- frequency of bus clock in Hz.
-
-- i2c-bus
- For I2C adapters that have child nodes that are a mixture of both I2C
- devices and non-I2C devices, the 'i2c-bus' subnode can be used for
- populating I2C devices. If the 'i2c-bus' subnode is present, only
- subnodes of this will be considered as I2C slaves. The properties,
- '#address-cells' and '#size-cells' must be defined under this subnode
- if present.
-
-- i2c-scl-falling-time-ns
- Number of nanoseconds the SCL signal takes to fall; t(f) in the I2C
- specification.
-
-- i2c-scl-internal-delay-ns
- Number of nanoseconds the IP core additionally needs to setup SCL.
-
-- i2c-scl-rising-time-ns
- Number of nanoseconds the SCL signal takes to rise; t(r) in the I2C
- specification.
-
-- i2c-sda-falling-time-ns
- Number of nanoseconds the SDA signal takes to fall; t(f) in the I2C
- specification.
-
-- i2c-analog-filter
- Enable analog filter for i2c lines.
-
-- i2c-digital-filter
- Enable digital filter for i2c lines.
-
-- i2c-digital-filter-width-ns
- Width of spikes which can be filtered by digital filter
- (i2c-digital-filter). This width is specified in nanoseconds.
-
-- i2c-analog-filter-cutoff-frequency
- Frequency that the analog filter (i2c-analog-filter) uses to distinguish
- which signal to filter. Signal with higher frequency than specified will
- be filtered out. Only lower frequency will pass (this is applicable to
- a low-pass analog filter). Typical value should be above the normal
- i2c bus clock frequency (clock-frequency).
- Specified in Hz.
-
-- multi-master
- states that there is another master active on this bus. The OS can use
- this information to adapt power management to keep the arbitration awake
- all the time, for example. Can not be combined with 'single-master'.
-
-- pinctrl
- add extra pinctrl to configure SCL/SDA pins to GPIO function for bus
- recovery, call it "gpio" or "recovery" (deprecated) state
-
-- scl-gpios
- specify the gpio related to SCL pin. Used for GPIO bus recovery.
-
-- sda-gpios
- specify the gpio related to SDA pin. Optional for GPIO bus recovery.
-
-- single-master
- states that there is no other master active on this bus. The OS can use
- this information to detect a stalled bus more reliably, for example.
- Can not be combined with 'multi-master'.
-
-- smbus
- states that additional SMBus restrictions and features apply to this bus.
- An example of feature is SMBusHostNotify. Examples of restrictions are
- more reserved addresses and timeout definitions.
-
-- smbus-alert
- states that the optional SMBus-Alert feature apply to this bus.
-
-- mctp-controller
- indicates that the system is accessible via this bus as an endpoint for
- MCTP over I2C transport.
-
-Required properties (per child device)
---------------------------------------
-
-- compatible
- name of I2C slave device
-
-- reg
- One or many I2C slave addresses. These are usually a 7 bit addresses.
- However, flags can be attached to an address. I2C_TEN_BIT_ADDRESS is
- used to mark a 10 bit address. It is needed to avoid the ambiguity
- between e.g. a 7 bit address of 0x50 and a 10 bit address of 0x050
- which, in theory, can be on the same bus.
- Another flag is I2C_OWN_SLAVE_ADDRESS to mark addresses on which we
- listen to be devices ourselves.
-
-Optional properties (per child device)
---------------------------------------
-
-These properties may not be supported by all drivers. However, if a driver
-wants to support one of the below features, it should adapt these bindings.
-
-- host-notify
- device uses SMBus host notify protocol instead of interrupt line.
-
-- interrupts
- interrupts used by the device.
-
-- interrupt-names
- "irq", "wakeup" and "smbus_alert" names are recognized by I2C core,
- other names are left to individual drivers.
-
-- reg-names
- Names of map programmable addresses.
- It can contain any map needing another address than default one.
-
-- wakeup-source
- device can be used as a wakeup source.
-
-Binding may contain optional "interrupts" property, describing interrupts
-used by the device. I2C core will assign "irq" interrupt (or the very first
-interrupt if not using interrupt names) as primary interrupt for the slave.
-
-Alternatively, devices supporting SMBus Host Notify, and connected to
-adapters that support this feature, may use "host-notify" property. I2C
-core will create a virtual interrupt for Host Notify and assign it as
-primary interrupt for the slave.
-
-Also, if device is marked as a wakeup source, I2C core will set up "wakeup"
-interrupt for the device. If "wakeup" interrupt name is not present in the
-binding, then primary interrupt will be used as wakeup interrupt.

+description: |
+ Analog Devices AD717x ADC's:
+ The AD717x family offer a complete integrated Sigma-Delta ADC solution which
+ can be used in high precision, low noise single channel applications
+ (Life Science measurements) or higher speed multiplexed applications
+ (Factory Automation PLC Input modules). The Sigma-Delta ADC is intended
+ primarily for measurement of signals close to DC but also delivers
+ outstanding performance with input bandwidths out to ~10kHz.
+
+ Analog Devices AD411x ADC's:
+ The AD411X family encompasses a series of low power, low noise, 24-bit,
+ sigma-delta analog-to-digital converters that offer a versatile range of
+ specifications. They integrate an analog front end suitable for processing
+ fully differential/single-ended and bipolar voltage inputs.

+ This property indicates the SPI wiring configuration.
+
+ When this property is omitted, it is assumed that the device is using what
+ the datasheet calls "4-wire mode". This is the conventional SPI mode used
+ when there are multiple devices on the same bus. In this mode, the CNV
+ line is used to initiate the conversion and the SDI line is connected to
+ CS on the SPI controller.
+
+ When this property is present, it indicates that the device is using one
+ of the following alternative wiring configurations:
+
+ * single: The datasheet calls this "3-wire mode". (NOTE: The datasheet's
+ definition of 3-wire mode is NOT at all related to the standard
+ spi-3wire property!) This mode is often used when the ADC is the only
+ device on the bus. In this mode, SDI is tied to VIO, and the CNV line
+ can be connected to the CS line of the SPI controller or to a GPIO, in
+ which case the CS line of the controller is unused.
+ * chain: The datasheet calls this "chain mode". This mode is used to save
+ on wiring when multiple ADCs are used. In this mode, the SDI line of
+ one chip is tied to the SDO of the next chip in the chain and the SDI of
+ the last chip in the chain is tied to GND. Only the first chip in the
+ chain is connected to the SPI bus. The CNV line of all chips are tied
+ together. The CS line of the SPI controller can be used as the CNV line
+ only if it is active high.

+ The ADE9000 is a highly accurate, fully integrated, multiphase energy and power
+ quality monitoring device. Superior analog performance and a digital signal
+ processing (DSP) core enable accurate energy monitoring over a wide dynamic

+ with a combined drift of less than ±25 ppm/°C maximum for the entire channel
+ including a programmable gain amplifier (PGA) and an analog-to-digital

+
+description: |
+ The MAX34408/MAX34409 are two- and four-channel current monitors that are
+ configured and monitored with a standard I2C/SMBus serial interface. Each
+ unidirectional current sensor offers precision high-side operation with a
+ low full-scale sense voltage. The devices automatically sequence through
+ two or four channels and collect the current-sense samples and average them
+ to reduce the effect of impulse noise. The raw ADC samples are compared to
+ user-programmable digital thresholds to indicate overcurrent conditions.
+ Overcurrent conditions trigger a hardware output to provide an immediate
+ indication to shut down any necessary external circuitry.
+
+ Specifications about the devices can be found at:

+description: |
+ The AD3530/AD3530R (8-channel) and AD3531/AD3531R (4-channel) are low-power,
+ 16-bit, buffered voltage output digital-to-analog converters (DACs) with
+ software-programmable gain controls, providing full-scale output spans of 2.5V
+ or 5V for reference voltages of 2.5V. These devices operate from a single 2.7V
+ to 5.5V supply and are guaranteed monotonic by design. The "R" variants
+ include a 2.5V, 5ppm/°C internal reference, which is disabled by default.

+title: Honeywell TruStability HSC and SSC pressure sensor series
+
+description: |
+ support for Honeywell TruStability HSC and SSC digital pressure sensor
+ series.
+
+ These sensors have either an I2C, an SPI or an analog interface. Only the
+ digital versions are supported by this driver.
+
+ There are 118 models with different pressure ranges available in each family.
+ The vendor calls them "HSC series" and "SSC series". All of them have an
+ identical programming model but differ in pressure range, unit and transfer
+ function.
+
+ To support different models one needs to specify the pressure range as well
+ as the transfer function. Pressure range can either be provided via
+ pressure-triplet (directly extracted from the part number) or in case it's
+ a custom chip via numerical range limits converted to pascals.
+
+ The transfer function defines the ranges of raw conversion values delivered
+ by the sensor. pmin-pascal and pmax-pascal corespond to the minimum and
+ maximum pressure that can be measured.
+
+ Please note that in case of an SPI-based sensor, the clock signal should not
+ exceed 800kHz and the MOSI signal is not required.
+
+ Specifications about the devices can be found at:
+ https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/products/sensors/pressure-sensors/board-mount-pressure-sensors/trustability-hsc-series/documents/sps-siot-trustability-hsc-series-high-accuracy-board-mount-pressure-sensors-50099148-a-en-ciid-151133.pdf

+
+description: |
+ Honeywell pressure sensor of model mprls0025pa.
+
+ This sensor has an I2C and SPI interface.
+
+ There are many models with different pressure ranges available. The vendor
+ calls them "mpr series". All of them have the identical programming model and
+ differ in the pressure range, unit and transfer function.
+
+ To support different models one need to specify its pressure triplet as well
+ as the transfer function.
+
+ For custom silicon chips not covered by the Honeywell MPR series datasheet,
+ the pressure values can be specified manually via honeywell,pmin-pascal and
+ honeywell,pmax-pascal.
+ The minimal range value stands for the minimum pressure and the maximum value
+ also for the maximum pressure with linear relation inside the range.
+
+ The transfer function defines the ranges of numerical values delivered by the
+ sensor.
+
+ Specifications about the devices can be found at:
+ https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/

+ Awinic's AW96103/AW96105 proximity sensor.
+ The specific absorption rate (SAR) is a metric that measures
+ the degree of absorption of electromagnetic radiation emitted by
+ wireless devices, such as mobile phones and tablets, by human tissue.
+ In mobile phone applications, the proximity sensor is primarily
+ used to detect the proximity of the human body to the phone. When the
+ phone approaches the human body, it will actively reduce the transmit
+ power of the antenna to keep the SAR within a safe range. Therefore,
+ we also refer to the proximity sensor as a SAR sensor.

+
+maintainers:

+
+description: |
+ The AD2S1210 is a complete 10-bit to 16-bit resolution tracking
+ resolver-to-digital converter, integrating an on-board programmable
+ sinusoidal oscillator that provides sine wave excitation for
+ resolvers.
+
+ The AD2S1210 allows the user to read the angular position or the
+ angular velocity data directly from the parallel outputs or through
+ the serial interface.
+
+ The mode of operation of the communication channel (parallel or serial) is
+ selected by the A0 and A1 input pins. In normal mode, data is latched by
+ toggling the SAMPLE line and can then be read directly. In configuration mode,
+ data is read or written using a register access scheme (address byte with
+ read/write flag and data byte).
+
+ A1 A0 Result
+ 0 0 Normal mode - position output
+ 0 1 Normal mode - velocity output
+ 1 0 Reserved
+ 1 1 Configuration mode
+
+ In normal mode, the resolution of the digital output is selected using
+ the RES0 and RES1 input pins. In configuration mode, the resolution is
+ selected by setting the RES0 and RES1 bits in the control register.
+
+ RES1 RES0 Resolution (Bits)
+ 0 0 10
+ 0 1 12
+ 1 0 14
+ 1 1 16
+
+ Note on SPI connections: The CS line on the AD2S1210 should hard-wired to
+ logic low and the WR/FSYNC line on the AD2S1210 should be connected to the
+ SPI CSn output of the SPI controller.

+
+ Following list of devices is an incomplete schema with a goal to pass DT schema

-Dialog Semiconductor DA7280 Haptics bindings
-
-Required properties:
-- compatible: Should be "dlg,da7280".
-- reg: Specifies the I2C slave address.
-
-- interrupt-parent : Specifies the phandle of the interrupt controller to
- which the IRQs from DA7280 are delivered to.
-
-- dlg,actuator-type: Set Actuator type. it should be one of:
- "LRA" - Linear Resonance Actuator type.
- "ERM-bar" - Bar type Eccentric Rotating Mass.
- "ERM-coin" - Coin type Eccentric Rotating Mass.
-
-- dlg,const-op-mode: Haptic operation mode for FF_CONSTANT.
- Possible values:
- 1 - Direct register override(DRO) mode triggered by i2c(default),
- 2 - PWM data source mode controlled by PWM duty,
-- dlg,periodic-op-mode: Haptic operation mode for FF_PERIODIC.
- Possible values:
- 1 - Register triggered waveform memory(RTWM) mode, the pattern
- assigned to the PS_SEQ_ID played as much times as PS_SEQ_LOOP,
- 2 - Edge triggered waveform memory(ETWM) mode, external GPI(N)
- control are required to enable/disable and it needs to keep
- device enabled by sending magnitude (X > 0),
- the pattern is assigned to the GPI(N)_SEQUENCE_ID below.
- The default value is 1 for both of the operation modes.
- For more details, please see the datasheet.
-
-- dlg,nom-microvolt: Nominal actuator voltage rating.
- Valid values: 0 - 6000000.
-- dlg,abs-max-microvolt: Absolute actuator maximum voltage rating.
- Valid values: 0 - 6000000.
-- dlg,imax-microamp: Actuator max current rating.
- Valid values: 0 - 252000.
- Default: 130000.
-- dlg,impd-micro-ohms: the impedance of the actuator in micro ohms.
- Valid values: 0 - 1500000000.
-
-Optional properties:
-- pwms : phandle to the physical PWM(Pulse Width Modulation) device.
- PWM properties should be named "pwms". And number of cell is different
- for each pwm device.
- (See Documentation/devicetree/bindings/pwm/pwm.txt
- for further information relating to pwm properties)
-
-- dlg,ps-seq-id: the PS_SEQ_ID(pattern ID in waveform memory inside chip)
- to play back when RTWM-MODE is enabled.
- Valid range: 0 - 15.
-- dlg,ps-seq-loop: the PS_SEQ_LOOP, Number of times the pre-stored sequence
- pointed to by PS_SEQ_ID or GPI(N)_SEQUENCE_ID is repeated.
- Valid range: 0 - 15.
-- dlg,gpiN-seq-id: the GPI(N)_SEQUENCE_ID, pattern to play
- when gpi0 is triggered, 'N' must be 0 - 2.
- Valid range: 0 - 15.
-- dlg,gpiN-mode: the pattern mode which can select either
- "Single-pattern" or "Multi-pattern", 'N' must be 0 - 2.
-- dlg,gpiN-polarity: gpiN polarity which can be chosen among
- "Rising-edge", "Falling-edge" and "Both-edge",
- 'N' must be 0 - 2
- Haptic will work by this edge option in case of ETWM mode.
-
-- dlg,resonant-freq-hz: use in case of LRA.
- the frequency range: 50 - 300.
- Default: 205.
-
-- dlg,bemf-sens-enable: Enable for internal loop computations.
-- dlg,freq-track-enable: Enable for resonant frequency tracking.

-* GPIO driven matrix keypad device tree bindings
-
-GPIO driven matrix keypad is used to interface a SoC with a matrix keypad.
-The matrix keypad supports multiple row and column lines, a key can be
-placed at each intersection of a unique row and a unique column. The matrix
-keypad can sense a key-press and key-release by means of GPIO lines and
-report the event using GPIO interrupts to the cpu.
-
-Required Properties:
-- compatible: Should be "gpio-matrix-keypad"
-- row-gpios: List of gpios used as row lines. The gpio specifier
- for this property depends on the gpio controller to
- which these row lines are connected.
-- col-gpios: List of gpios used as column lines. The gpio specifier
- for this property depends on the gpio controller to
- which these column lines are connected.
-- linux,keymap: The definition can be found at
- bindings/input/matrix-keymap.txt
-
-Optional Properties:
-- linux,no-autorepeat: do no enable autorepeat feature.
-- wakeup-source: use any event on keypad as wakeup event.
- (Legacy property supported: "linux,wakeup")
-- debounce-delay-ms: debounce interval in milliseconds
-- col-scan-delay-us: delay, measured in microseconds, that is needed
- before we can scan keypad after activating column gpio
-- drive-inactive-cols: drive inactive columns during scan,
- default is to turn inactive columns into inputs.
-
-Example:
- matrix-keypad {
- compatible = "gpio-matrix-keypad";
- debounce-delay-ms = <5>;
- col-scan-delay-us = <2>;

-SPI driven touch screen controllers.
-
-The node for this driver must be a child node of a SPI controller, hence
-all mandatory properties described in
-
- Documentation/devicetree/bindings/spi/spi-bus.txt
-
-must be specified.
-
-Additional required properties:
-
- compatible Must be one of the following, depending on the

- This value depends on the touch screen.
-- pre-charge-time: the touch screen need some time to precharge.
- This value depends on the touch screen.
-- touchscreen-average-samples: Number of data samples which are averaged for
- each read. Valid values are 1, 4, 8, 16 and 32.

+ description: |
+ List of nodes defining segments (touch areas) on the touchscreen.
+
+ This object can be used to describe a series of segments to restrict
+ the region within touch events are reported or buttons with a specific
+ functionality.
+
+ This is of special interest if the touchscreen is shipped with a physical
+ overlay on top of it with a frame that hides some part of the original
+ touchscreen area. Printed buttons on that overlay are also a typical
+ use case.
+
+ A new touchscreen area is defined as a sub-node without a key code. If a
+ key code is defined in the sub-node, it will be interpreted as a button.
+
+ The x-origin and y-origin properties of a touchscreen area define the
+ offset of a new origin from where the touchscreen events are referenced.
+ This offset is applied to the events accordingly. The x-size and y-size
+ properties define the size of the touchscreen effective area.
+
+ The following example shows a new touchscreen area with the new origin
+ (0',0') for the touch events generated by the device.
+
+ Touchscreen (full area)
+ ┌────────────────────────────────────────┐
+ │ ┌───────────────────────────────┐ │

+ (0,0)
+
+ where (0',0') = (0+x-origin,0+y-origin)
+
+ Sub-nodes with key codes report the touch events on their surface as key
+ events instead.
+
+ The following example shows a touchscreen with a single button on it.
+

+
+ Segments defining buttons and clipped toushcreen areas can be combined
+ as shown in the following example.
+ In that case only the events within the touchscreen area are reported
+ as touch events. Events within the button areas report their associated
+ key code. Any events outside the defined areas are ignored.

-TB10x Top Level Interrupt Controller
-====================================
-
-The Abilis TB10x SOC contains a custom interrupt controller. It performs
-one-to-one mapping of external interrupt sources to CPU interrupts and
-provides support for reconfigurable trigger modes.
-
-Required properties
--------------------
-
-- compatible: Should be "abilis,tb10x-ictl"
-- reg: specifies physical base address and size of register range.
-- interrupt-congroller: Identifies the node as an interrupt controller.
-- #interrupt cells: Specifies the number of cells used to encode an interrupt
- source connected to this controller. The value shall be 2.
-- interrupts: Specifies the list of interrupt lines which are handled by
- the interrupt controller in the parent controller's notation. Interrupts
- are mapped one-to-one to parent interrupts.
-
-Example
--------
-
-intc: interrupt-controller { /* Parent interrupt controller */
- interrupt-controller;
- #interrupt-cells = <1>; /* For example below */
- /* ... */
-};
-
-tb10x_ictl: pic@2000 { /* TB10x interrupt controller */
- compatible = "abilis,tb10x-ictl";
- reg = <0x2000 0x20>;
- interrupt-controller;
- #interrupt-cells = <2>;
- interrupt-parent = <&intc>;
- interrupts = <5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
- 20 21 22 23 24 25 26 27 28 29 30 31>;

- sources. The cell is a u32 and defines the interrupt number.
-- reg: The register bank for the FPGA interrupt controller.
-- clear-mask: a u32 number representing the mask written to clear all IRQs
- on the controller at boot for example.
-- valid-mask: a u32 number representing a bit mask determining which of
- the interrupts are valid. Unconnected/unused lines are set to 0, and
- the system till not make it possible for devices to request these
- interrupts.
-
-Example:
-
-pic: pic@14000000 {
- compatible = "arm,versatile-fpga-irq";
- #interrupt-cells = <1>;
- interrupt-controller;
- reg = <0x14000000 0x100>;
- clear-mask = <0xffffffff>;
- valid-mask = <0x003fffff>;
-};
-
-Optional properties:
-- interrupts: if the FPGA IRQ controller is cascaded, i.e. if its IRQ
- output is simply connected to the input of another IRQ controller,
- then the parent IRQ shall be specified in this property.

-BCM2835 Top-Level ("ARMCTRL") Interrupt Controller
-
-The BCM2835 contains a custom top-level interrupt controller, which supports
-72 interrupt sources using a 2-level register scheme. The interrupt
-controller, or the HW block containing it, is referred to occasionally
-as "armctrl" in the SoC documentation, hence naming of this binding.
-
-The BCM2836 contains the same interrupt controller with the same
-interrupts, but the per-CPU interrupt controller is the root, and an
-interrupt there indicates that the ARMCTRL has an interrupt to handle.
-
-Required properties:
-
-- compatible : should be "brcm,bcm2835-armctrl-ic" or
- "brcm,bcm2836-armctrl-ic"
-- reg : Specifies base physical address and size of the registers.
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an

+description: >
+ The BCM2835 contains a custom top-level interrupt controller, which supports
+ 72 interrupt sources using a 2-level register scheme. The interrupt
+ controller, or the HW block containing it, is referred to occasionally as
+ "armctrl" in the SoC documentation, hence naming of this binding.
+
+ The BCM2836 contains the same interrupt controller with the same interrupts,
+ but the per-CPU interrupt controller is the root, and an interrupt there
+ indicates that the ARMCTRL has an interrupt to handle.
+
+ The interrupt sources are as follows:
+
+ Bank 0:
+ 0: ARM_TIMER
+ 1: ARM_MAILBOX
+ 2: ARM_DOORBELL_0

-Broadcom BCM6345-style Level 1 interrupt controller

-
-Key elements of the hardware design include:
-
-- 32, 64 or 128 incoming level IRQ lines
-
-- Most onchip peripherals are wired directly to an L1 input
-
-- A separate instance of the register set for each CPU, allowing individual
- peripheral IRQs to be routed to any CPU
-
-- Contains one or more enable/status word pairs per CPU
-
-- No atomic set/clear operations
-
-- No polarity/level/edge settings
-
-- No FIFO or priority encoder logic; software is expected to read all
- 2-4 status words to determine which IRQs are pending
-
-Required properties:
-
-- compatible: should be "brcm,bcm<soc>-l1-intc", "brcm,bcm6345-l1-intc"
-- reg: specifies the base physical address and size of the registers;
- the number of supported IRQs is inferred from the size argument
-- interrupt-controller: identifies the node as an interrupt controller
-- #interrupt-cells: specifies the number of cells needed to encode an interrupt
- source, should be 1.
-- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
- node; valid values depend on the type of parent interrupt controller
-
-If multiple reg ranges and interrupt-parent entries are present on an SMP
-system, the driver will allow IRQ SMP affinity to be set up through the
-/proc/irq/ interface. In the simplest possible configuration, only one
-reg range and one interrupt-parent is needed.

+title: Freescale i.MX8qxp Display Controller interrupt controller
+
+description: |
+ The Display Controller has a built-in interrupt controller with the following
+ features for all relevant HW events:
+
+ * Enable bit (mask)
+ * Status bit (set by an HW event)
+ * Preset bit (can be used by SW to set status)
+ * Clear bit (used by SW to reset the status)
+
+ Each interrupt can be connected as IRQ (maskable) and/or NMI (non-maskable).
+ Alternatively the un-masked trigger signals for all HW events are provided,
+ allowing it to use a global interrupt controller instead.
+
+ Each interrupt can be protected against SW running in user mode. In that case,
+ only privileged AHB access can control the interrupt status.

+description: |
+ The Freescale hypervisor and msi-address-64
+ -------------------------------------------
+
+ Normally, PCI devices have access to all of CCSR via an ATMU mapping. The
+ Freescale MSI driver calculates the address of MSIIR (in the MSI register
+ block) and sets that address as the MSI message address.
+
+ In a virtualized environment, the hypervisor may need to create an IOMMU
+ mapping for MSIIR. The Freescale ePAPR hypervisor has this requirement
+ because of hardware limitations of the Peripheral Access Management Unit
+ (PAMU), which is currently the only IOMMU that the hypervisor supports.
+ The ATMU is programmed with the guest physical address, and the PAMU
+ intercepts transactions and reroutes them to the true physical address.
+
+ In the PAMU, each PCI controller is given only one primary window. The
+ PAMU restricts DMA operations so that they can only occur within a window.
+ Because PCI devices must be able to DMA to memory, the primary window must
+ be used to cover all of the guest's memory space.
+
+ PAMU primary windows can be divided into 256 subwindows, and each
+ subwindow can have its own address mapping ("guest physical" to "true
+ physical"). However, each subwindow has to have the same alignment, which
+ means they cannot be located at just any address. Because of these
+ restrictions, it is usually impossible to create a 4KB subwindow that
+ covers MSIIR where it's normally located.
+
+ Therefore, the hypervisor has to create a subwindow inside the same
+ primary window used for memory, but mapped to the MSIR block (where MSIIR
+ lives). The first subwindow after the end of guest memory is used for
+ this. The address specified in the msi-address-64 property is the PCI
+ address of MSIIR. The hypervisor configures the PAMU to map that address to
+ the true physical address of MSIIR.

-Hisilicon mbigen device tree bindings.
-=======================================
-
-Mbigen means: message based interrupt generator.
-
-MBI is kind of msi interrupt only used on Non-PCI devices.
-
-To reduce the wired interrupt number connected to GIC,
-Hisilicon designed mbigen to collect and generate interrupt.
-
-
-Non-pci devices can connect to mbigen and generate the
-interrupt by writing ITS register.
-
-The mbigen chip and devices connect to mbigen have the following properties:
-
-Mbigen main node required properties:
--------------------------------------------
-- compatible: Should be "hisilicon,mbigen-v2"
-
-- reg: Specifies the base physical address and size of the Mbigen
- registers.
-
-Mbigen sub node required properties:
-------------------------------------------
-- interrupt controller: Identifies the node as an interrupt controller
-
-- msi-parent: Specifies the MSI controller this mbigen use.
- For more detail information,please refer to the generic msi-parent binding in
- Documentation/devicetree/bindings/interrupt-controller/msi.txt.
-
-- num-pins: the total number of pins implemented in this Mbigen
- instance.
-
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source. The value must be 2.
-
- The 1st cell is hardware pin number of the interrupt.This number is local to
- each mbigen chip and in the range from 0 to the maximum interrupts number
- of the mbigen.
-
- The 2nd cell is the interrupt trigger type.
- The value of this cell should be:
- 1: rising edge triggered
- or
- 4: high level triggered
-
-Examples:
-
- mbigen_chip_dsa {
- compatible = "hisilicon,mbigen-v2";
- reg = <0x0 0xc0080000 0x0 0x10000>;
-
- mbigen_gmac:intc_gmac {
- interrupt-controller;
- msi-parent = <&its_dsa 0x40b1c>;
- num-pins = <9>;
- #interrupt-cells = <2>;
- };
-
- mbigen_i2c:intc_i2c {
- interrupt-controller;
- msi-parent = <&its_dsa 0x40b0e>;
- num-pins = <2>;
- #interrupt-cells = <2>;
- };
- };
-
-Devices connect to mbigen required properties:
-----------------------------------------------------
--interrupts:Specifies the interrupt source.
- For the specific information of each cell in this property,please refer to
- the "interrupt-cells" description mentioned above.
-
-Examples:
- gmac0: ethernet@c2080000 {
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0 0xc2080000 0 0x20000>,
- <0 0xc0000000 0 0x1000>;
- interrupt-parent = <&mbigen_device_gmac>;
- interrupts = <656 1>,
- <657 1>;

-* ImgTec Powerdown Controller (PDC) Interrupt Controller Binding
-
-This binding specifies what properties must be available in the device tree
-representation of a PDC IRQ controller. This has a number of input interrupt
-lines which can wake the system, and are passed on through output interrupt
-lines.
-
-Required properties:
-
- - compatible: Specifies the compatibility list for the interrupt controller.
- The type shall be <string> and the value shall include "img,pdc-intc".
-
- - reg: Specifies the base PDC physical address(s) and size(s) of the
- addressable register space. The type shall be <prop-encoded-array>.
-
- - interrupt-controller: The presence of this property identifies the node
- as an interrupt controller. No property value shall be defined.
-
- - #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt source. The type shall be a <u32> and the value shall be 2.
-
- - num-perips: Number of waking peripherals.
-
- - num-syswakes: Number of SysWake inputs.
-
- - interrupts: List of interrupt specifiers. The first specifier shall be the
- shared SysWake interrupt, and remaining specifies shall be PDC peripheral
- interrupts in order.
-
-* Interrupt Specifier Definition
-
- Interrupt specifiers consists of 2 cells encoded as follows:
-
- - <1st-cell>: The interrupt-number that identifies the interrupt source.
- 0-7: Peripheral interrupts
- 8-15: SysWake interrupts
-
- - <2nd-cell>: The level-sense information, encoded using the Linux interrupt
- flags as follows (only 4 valid for peripheral interrupts):
- 0 = none (decided by software)
- 1 = low-to-high edge triggered
- 2 = high-to-low edge triggered
- 3 = both edge triggered
- 4 = active-high level-sensitive (required for perip irqs)
- 8 = active-low level-sensitive
-
-* Examples
-
-Example 1:
-
- /*
- * TZ1090 PDC block
- */
- pdc: pdc@02006000 {
- // This is an interrupt controller node.
- interrupt-controller;
-
- // Three cells to encode interrupt sources.
- #interrupt-cells = <2>;
-
- // Offset address of 0x02006000 and size of 0x1000.
- reg = <0x02006000 0x1000>;
-
- // Compatible with Meta hardware trigger block.
- compatible = "img,pdc-intc";
-
- // Three peripherals are connected.
- num-perips = <3>;
-
- // Four SysWakes are connected.
- num-syswakes = <4>;
-
- interrupts = <18 4 /* level */>, /* Syswakes */
- <30 4 /* level */>, /* Peripheral 0 (RTC) */
- <29 4 /* level */>, /* Peripheral 1 (IR) */
- <31 4 /* level */>; /* Peripheral 2 (WDT) */
- };
-
-Example 2:
-
- /*
- * An SoC peripheral that is wired through the PDC.
- */
- rtc0 {
- // The interrupt controller that this device is wired to.
- interrupt-parent = <&pdc>;
-
- // Interrupt source Peripheral 0
- interrupts = <0 /* Peripheral 0 (RTC) */
- 4> /* IRQ_TYPE_LEVEL_HIGH */
- };
-
-Example 3:
-
- /*
- * An interrupt generating device that is wired to a SysWake pin.
- */
- touchscreen0 {
- // The interrupt controller that this device is wired to.
- interrupt-parent = <&pdc>;
-
- // Interrupt source SysWake 0 that is active-low level-sensitive
- interrupts = <8 /* SysWake0 */
- 8 /* IRQ_TYPE_LEVEL_LOW */>;

-J-Core Advanced Interrupt Controller
-
-Required properties:
-
-- compatible: Should be "jcore,aic1" for the (obsolete) first-generation aic
- with 8 interrupt lines with programmable priorities, or "jcore,aic2" for
- the "aic2" core with 64 interrupts.
-
-- reg: Memory region(s) for configuration. For SMP, there should be one
- region per cpu, indexed by the sequential, zero-based hardware cpu
- number.
-
-- interrupt-controller: Identifies the node as an interrupt controller
-
-- #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt source. The value shall be 1.
-
-
-Example:
-
-aic: interrupt-controller@200 {
- compatible = "jcore,aic2";
- reg = < 0x200 0x30 0x500 0x30 >;
- interrupt-controller;
- #interrupt-cells = <1>;

-Marvell Armada 370, 375, 38x, XP Interrupt Controller
------------------------------------------------------
-
-Required properties:
-- compatible: Should be "marvell,mpic"
-- interrupt-controller: Identifies the node as an interrupt controller.
-- msi-controller: Identifies the node as an PCI Message Signaled
- Interrupt controller.
-- #interrupt-cells: The number of cells to define the interrupts. Should be 1.
- The cell is the IRQ number
-
-- reg: Should contain PMIC registers location and length. First pair
- for the main interrupt registers, second pair for the per-CPU
- interrupt registers. For this last pair, to be compliant with SMP
- support, the "virtual" must be use (For the record, these registers
- automatically map to the interrupt controller registers of the
- current CPU)
-
-Optional properties:
-
-- interrupts: If defined, then it indicates that this MPIC is
- connected as a slave to another interrupt controller. This is
- typically the case on Armada 375 and Armada 38x, where the MPIC is
- connected as a slave to the Cortex-A9 GIC. The provided interrupt
- indicate to which GIC interrupt the MPIC output is connected.
-
-Example:
-
- mpic: interrupt-controller@d0020000 {
- compatible = "marvell,mpic";

-Marvell GICP Controller
------------------------
-
-GICP is a Marvell extension of the GIC that allows to trigger GIC SPI
-interrupts by doing a memory transaction. It is used by the ICU
-located in the Marvell CP110 to turn wired interrupts inside the CP
-into GIC SPI interrupts.
-
-Required properties:
-
-- compatible: Must be "marvell,ap806-gicp"
-
-- reg: Must be the address and size of the GICP SPI registers
-
-- marvell,spi-ranges: tuples of GIC SPI interrupts ranges available
- for this GICP
-
-- msi-controller: indicates that this is an MSI controller
-
-Example:

-Required properties for the icu_nsr/icu_sei subnodes:
-
-- compatible: Should be one of:

-
-- interrupt-controller: Identifies the node as an interrupt

-
-Note: each 'interrupts' property referring to any 'icu_xxx' node shall
- have a different number within [0:206].
-
-Example:
-
-icu: interrupt-controller@1e0000 {

-Marvell SEI (System Error Interrupt) Controller
------------------------------------------------
-
-Marvell SEI (System Error Interrupt) controller is an interrupt
-aggregator. It receives interrupts from several sources and aggregates
-them to a single interrupt line (an SPI) on the parent interrupt
-controller.
-
-This interrupt controller can handle up to 64 SEIs, a set comes from the
-AP and is wired while a second set comes from the CPs by the mean of
-MSIs.
-
-Required properties:
-
-- compatible: should be one of:
- * "marvell,ap806-sei"
-- reg: SEI registers location and length.
-- interrupts: identifies the parent IRQ that will be triggered.
-- #interrupt-cells: number of cells to define an SEI wired interrupt
- coming from the AP, should be 1. The cell is the IRQ
- number.
-- interrupt-controller: identifies the node as an interrupt controller
- for AP interrupts.
-- msi-controller: identifies the node as an MSI controller for the CPs
- interrupts.
-
-Example:
-
- sei: interrupt-controller@3f0200 {
- compatible = "marvell,ap806-sei";
- reg = <0x3f0200 0x40>;

-Microchip PIC32 Interrupt Controller
-====================================
-
-The Microchip PIC32 contains an Enhanced Vectored Interrupt Controller (EVIC).
-It handles all internal and external interrupts. This controller exists outside
-of the CPU and is the arbitrator of all interrupts (including interrupts from
-the CPU itself) before they are presented to the CPU.
-
-External interrupts have a software configurable edge polarity. Non external
-interrupts have a type and polarity that is determined by the source of the
-interrupt.
-
-Required properties
--------------------
-
-- compatible: Should be "microchip,pic32mzda-evic"
-- reg: Specifies physical base address and size of register range.
-- interrupt-controller: Identifies the node as an interrupt controller.
-- #interrupt cells: Specifies the number of cells used to encode an interrupt
- source connected to this controller. The value shall be 2 and interrupt
- descriptor shall have the following format:
-
- <hw_irq irq_type>
-
- hw_irq - represents the hardware interrupt number as in the data sheet.
- irq_type - is used to describe the type and polarity of an interrupt. For
- internal interrupts use IRQ_TYPE_EDGE_RISING for non persistent interrupts and
- IRQ_TYPE_LEVEL_HIGH for persistent interrupts. For external interrupts use
- IRQ_TYPE_EDGE_RISING or IRQ_TYPE_EDGE_FALLING to select the desired polarity.
-
-Optional properties
--------------------
-- microchip,external-irqs: u32 array of external interrupts with software
- polarity configuration. This array corresponds to the bits in the INTCON
- SFR.
-
-Example
--------
-
-evic: interrupt-controller@1f810000 {
- compatible = "microchip,pic32mzda-evic";
- interrupt-controller;
- #interrupt-cells = <2>;
- reg = <0x1f810000 0x1000>;
- microchip,external-irqs = <3 8 13 18 23>;
-};
-
-Each device/peripheral must request its interrupt line with the associated type
-and polarity.
-
-Internal interrupt DTS snippet
-------------------------------
-
-device@1f800000 {
- ...
- interrupts = <113 IRQ_TYPE_LEVEL_HIGH>;
- ...
-};
-
-External interrupt DTS snippet
-------------------------------
-
-device@1f800000 {
- ...
- interrupts = <3 IRQ_TYPE_EDGE_RISING>;
- ...
-};

-NVIDIA Legacy Interrupt Controller
-
-All Tegra SoCs contain a legacy interrupt controller that routes
-interrupts to the GIC, and also serves as a wakeup source. It is also
-referred to as "ictlr", hence the name of the binding.
-
-The HW block exposes a number of interrupt controllers, each
-implementing a set of 32 interrupts.
-
-Required properties:
-
-- compatible : should be: "nvidia,tegra<chip>-ictlr". The LIC on
- subsequent SoCs remained backwards-compatible with Tegra30, so on
- Tegra generations later than Tegra30 the compatible value should
- include "nvidia,tegra30-ictlr".
-- reg : Specifies base physical address and size of the registers.
- Each controller must be described separately (Tegra20 has 4 of them,
- whereas Tegra30 and later have 5).
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source. The value must be 3.
-
-Notes:
-
-- Because this HW ultimately routes interrupts to the GIC, the
- interrupt specifier must be that of the GIC.
-- Only SPIs can use the ictlr as an interrupt parent. SGIs and PPIs
- are explicitly forbidden.
-
-Example:
-
- ictlr: interrupt-controller@60004000 {

-* Open PIC Binding
-
-This binding specifies what properties must be available in the device tree
-representation of an Open PIC compliant interrupt controller. This binding is
-based on the binding defined for Open PIC in [1] and is a superset of that
-binding.
-
-Required properties:
-
- NOTE: Many of these descriptions were paraphrased here from [1] to aid
- readability.
-
- - compatible: Specifies the compatibility list for the PIC. The type
- shall be <string> and the value shall include "open-pic".
-
- - reg: Specifies the base physical address(s) and size(s) of this
- PIC's addressable register space. The type shall be <prop-encoded-array>.
-
- - interrupt-controller: The presence of this property identifies the node
- as an Open PIC. No property value shall be defined.
-
- - #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt source. The type shall be a <u32> and the value shall be 2.
-
- - #address-cells: Specifies the number of cells needed to encode an
- address. The type shall be <u32> and the value shall be 0. As such,
- 'interrupt-map' nodes do not have to specify a parent unit address.
-
-Optional properties:
-
- - pic-no-reset: The presence of this property indicates that the PIC
- shall not be reset during runtime initialization. No property value shall
- be defined. The presence of this property also mandates that any
- initialization related to interrupt sources shall be limited to sources
- explicitly referenced in the device tree.
-
-* Interrupt Specifier Definition
-
- Interrupt specifiers consists of 2 cells encoded as
- follows:
-
- - <1st-cell>: The interrupt-number that identifies the interrupt source.
-
- - <2nd-cell>: The level-sense information, encoded as follows:
- 0 = low-to-high edge triggered
- 1 = active low level-sensitive
- 2 = active high level-sensitive
- 3 = high-to-low edge triggered
-
-* Examples
-
-Example 1:
-
- /*
- * An Open PIC interrupt controller
- */
- mpic: pic@40000 {
- // This is an interrupt controller node.
- interrupt-controller;
-
- // No address cells so that 'interrupt-map' nodes which reference
- // this Open PIC node do not need a parent address specifier.
- #address-cells = <0>;
-
- // Two cells to encode interrupt sources.
- #interrupt-cells = <2>;
-
- // Offset address of 0x40000 and size of 0x40000.
- reg = <0x40000 0x40000>;
-
- // Compatible with Open PIC.
- compatible = "open-pic";
-
- // The PIC shall not be reset.
- pic-no-reset;
- };
-
-Example 2:
-
- /*
- * An interrupt generating device that is wired to an Open PIC.
- */
- serial0: serial@4500 {
- // Interrupt source '42' that is active high level-sensitive.
- // Note that there are only two cells as specified in the interrupt
- // parent's '#interrupt-cells' property.
- interrupts = <42 2>;
-
- // The interrupt controller that this device is wired to.
- interrupt-parent = <&mpic>;
- };

-RISC-V Hart-Level Interrupt Controller (HLIC)
----------------------------------------------
-
-RISC-V cores include Control Status Registers (CSRs) which are local to each
-CPU core (HART in RISC-V terminology) and can be read or written by software.
-Some of these CSRs are used to control local interrupts connected to the core.
-Every interrupt is ultimately routed through a hart's HLIC before it
-interrupts that hart.
-
-The RISC-V supervisor ISA manual specifies three interrupt sources that are
-attached to every HLIC: software interrupts, the timer interrupt, and external
-interrupts. Software interrupts are used to send IPIs between cores. The
-timer interrupt comes from an architecturally mandated real-time timer that is
-controlled via Supervisor Binary Interface (SBI) calls and CSR reads. External
-interrupts connect all other device interrupts to the HLIC, which are routed
-via the platform-level interrupt controller (PLIC).
-
-All RISC-V systems that conform to the supervisor ISA specification are
-required to have a HLIC with these three interrupt sources present. Since the
-interrupt map is defined by the ISA it's not listed in the HLIC's device tree
-entry, though external interrupt controllers (like the PLIC, for example) will
-need to define how their interrupts map to the relevant HLICs. This means
-a PLIC interrupt property will typically list the HLICs for all present HARTs
-in the system.
-
-Required properties:
-- compatible : "riscv,cpu-intc"
-- #interrupt-cells : should be <1>. The interrupt sources are defined by the
- RISC-V supervisor ISA manual, with only the following three interrupts being
- defined for supervisor mode:
- - Source 1 is the supervisor software interrupt, which can be sent by an SBI
- call and is reserved for use by software.
- - Source 5 is the supervisor timer interrupt, which can be configured by
- SBI calls and implements a one-shot timer.
- - Source 9 is the supervisor external interrupt, which chains to all other
- device interrupts.
-- interrupt-controller : Identifies the node as an interrupt controller
-
-Furthermore, this interrupt-controller MUST be embedded inside the cpu
-definition of the hart whose CSRs control these local interrupts.
-
-An example device tree entry for a HLIC is show below.
-
- cpu1: cpu@1 {
- compatible = "riscv";
- ...
- cpu1-intc: interrupt-controller {
- #interrupt-cells = <1>;
- compatible = "sifive,fu540-c000-cpu-intc", "riscv,cpu-intc";

+title: RISC-V Incoming MSI Controller (IMSIC)
+
+maintainers:
+ - Anup Patel <anup@brainfault.org>
+
+description: |
+ The RISC-V advanced interrupt architecture (AIA) defines a per-CPU incoming
+ MSI controller (IMSIC) for handling MSIs in a RISC-V platform. The RISC-V
+ AIA specification can be found at https://github.com/riscv/riscv-aia.
+
+ The IMSIC is a per-CPU (or per-HART) device with separate interrupt file
+ for each privilege level (machine or supervisor). The configuration of
+ a IMSIC interrupt file is done using AIA CSRs and it also has a 4KB MMIO
+ space to receive MSIs from devices. Each IMSIC interrupt file supports a
+ fixed number of interrupt identities (to distinguish MSIs from devices)
+ which is same for given privilege level across CPUs (or HARTs).
+
+ The device tree of a RISC-V platform will have one IMSIC device tree node
+ for each privilege level (machine or supervisor) which collectively describe
+ IMSIC interrupt files at that privilege level across CPUs (or HARTs).
+
+ The arrangement of IMSIC interrupt files in MMIO space of a RISC-V platform
+ follows a particular scheme defined by the RISC-V AIA specification. A IMSIC
+ group is a set of IMSIC interrupt files co-located in MMIO space and we can
+ have multiple IMSIC groups (i.e. clusters, sockets, chiplets, etc) in a
+ RISC-V platform. The MSI target address of a IMSIC interrupt file at given
+ privilege level (machine or supervisor) encodes group index, HART index,
+ and guest index (shown below).

-Properties:
-
-- compatible: "snps,archs-idu-intc"
-- interrupt-controller: This is an interrupt controller.
-- #interrupt-cells: Must be <1> or <2>.
-
- Value of the first cell specifies the "common" IRQ from peripheral to IDU.
- Number N of the particular interrupt line of IDU corresponds to the line N+24
- of the core interrupt controller.
-
- The (optional) second cell specifies any of the following flags:
- - bits[3:0] trigger type and level flags
- 1 = low-to-high edge triggered
- 2 = NOT SUPPORTED (high-to-low edge triggered)
- 4 = active high level-sensitive <<< DEFAULT
- 8 = NOT SUPPORTED (active low level-sensitive)
- When no second cell is specified, the interrupt is assumed to be level
- sensitive.
-
- The interrupt controller is accessed via the special ARC AUX register
- interface, hence "reg" property is not specified.

-Synopsys DesignWare APB interrupt controller (dw_apb_ictl)
-
-Synopsys DesignWare provides interrupt controller IP for APB known as
-dw_apb_ictl. The IP is used as secondary interrupt controller in some SoCs with
-APB bus, e.g. Marvell Armada 1500. It can also be used as primary interrupt
-controller in some SoCs, e.g. Hisilicon SD5203.
-
-Required properties:
-- compatible: shall be "snps,dw-apb-ictl"
-- reg: physical base address of the controller and length of memory mapped
- region starting with ENABLE_LOW register
-- interrupt-controller: identifies the node as an interrupt controller
-- #interrupt-cells: number of cells to encode an interrupt-specifier, shall be 1
-
-Additional required property when it's used as secondary interrupt controller:
-- interrupts: interrupt reference to primary interrupt controller
-
-The interrupt sources map to the corresponding bits in the interrupt
-registers, i.e.
-- 0 maps to bit 0 of low interrupts,
-- 1 maps to bit 1 of low interrupts,
-- 32 maps to bit 0 of high interrupts,
-- 33 maps to bit 1 of high interrupts,
-- (optional) fast interrupts start at 64.

- /* dw_apb_ictl is used as secondary interrupt controller */

+description: |
+ SPEAr3xx architecture includes shared/multiplexed irqs for certain set of
+ devices. The multiplexor provides a single interrupt to parent interrupt
+ controller (VIC) on behalf of a group of devices.
+
+ There can be multiple groups available on SPEAr3xx variants but not exceeding
+ 4. The number of devices in a group can differ, further they may share same
+ set of status/mask registers spanning across different bit masks. Also in some
+ cases the group may not have enable or other registers. This makes software
+ little complex.
+
+ A single node in the device tree is used to describe the shared interrupt
+ multiplexer (one node for all groups). A group in the interrupt controller
+ shares config/control registers with other groups. For example, a 32-bit
+ interrupt enable/disable config register can accommodate up to 4 interrupt
+ groups.

-* SPEAr Shared IRQ layer (shirq)
-
-SPEAr3xx architecture includes shared/multiplexed irqs for certain set
-of devices. The multiplexor provides a single interrupt to parent
-interrupt controller (VIC) on behalf of a group of devices.
-
-There can be multiple groups available on SPEAr3xx variants but not
-exceeding 4. The number of devices in a group can differ, further they
-may share same set of status/mask registers spanning across different
-bit masks. Also in some cases the group may not have enable or other
-registers. This makes software little complex.
-
-A single node in the device tree is used to describe the shared
-interrupt multiplexor (one node for all groups). A group in the
-interrupt controller shares config/control registers with other groups.
-For example, a 32-bit interrupt enable/disable config register can
-accommodate up to 4 interrupt groups.
-
-Required properties:
- - compatible: should be, either of
- - "st,spear300-shirq"
- - "st,spear310-shirq"
- - "st,spear320-shirq"
- - interrupt-controller: Identifies the node as an interrupt controller.
- - #interrupt-cells: should be <1> which basically contains the offset
- (starting from 0) of interrupts for all the groups.
- - reg: Base address and size of shirq registers.
- - interrupts: The list of interrupts generated by the groups which are
- then connected to a parent interrupt controller. Each group is
- associated with one of the interrupts, hence number of interrupts (to
- parent) is equal to number of groups. The format of the interrupt
- specifier depends in the interrupt parent controller.
-
-Example:
-
-The following is an example from the SPEAr320 SoC dtsi file.
-
-shirq: interrupt-controller@b3000000 {
- compatible = "st,spear320-shirq";
- reg = <0xb3000000 0x1000>;
- interrupts = <28 29 30 1>;
- #interrupt-cells = <1>;
- interrupt-controller;

-STMicroelectronics STi System Configuration Controlled IRQs
------------------------------------------------------------
-
-On STi based systems; External, CTI (Core Sight), PMU (Performance Management),
-and PL310 L2 Cache IRQs are controlled using System Configuration registers.
-This driver is used to unmask them prior to use.
-
-Required properties:
-- compatible : Should be set to one of:
- "st,stih415-irq-syscfg"
- "st,stih416-irq-syscfg"
- "st,stih407-irq-syscfg"
- "st,stid127-irq-syscfg"
-- st,syscfg : Phandle to Cortex-A9 IRQ system config registers
-- st,irq-device : Array of IRQs to enable - should be 2 in length
-- st,fiq-device : Array of FIQs to enable - should be 2 in length
-
-Optional properties:
-- st,invert-ext : External IRQs can be inverted at will. This property inverts
- these IRQs using bitwise logic. A number of defines have been
- provided for convenience:
- ST_IRQ_SYSCFG_EXT_1_INV
- ST_IRQ_SYSCFG_EXT_2_INV
- ST_IRQ_SYSCFG_EXT_3_INV
-Example:
-
-irq-syscfg {
- compatible = "st,stih416-irq-syscfg";
- st,syscfg = <&syscfg_cpu>;
- st,irq-device = <ST_IRQ_SYSCFG_PMU_0>,

- st,fiq-device = <ST_IRQ_SYSCFG_DISABLED>,
- <ST_IRQ_SYSCFG_DISABLED>;
- st,invert-ext = <(ST_IRQ_SYSCFG_EXT_1_INV | ST_IRQ_SYSCFG_EXT_3_INV)>;

-* OMAP Interrupt Controller
-
-OMAP2/3 are using a TI interrupt controller that can support several
-configurable number of interrupts.
-
-Main node required properties:
-
-- compatible : should be:
- "ti,omap2-intc"
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source. The type shall be a <u32> and the value shall be 1.
-
- The cell contains the interrupt number in the range [0-128].
-- ti,intc-size: Number of interrupts handled by the interrupt controller.
-- reg: physical base address and size of the intc registers map.
-
-Example:
-
- intc: interrupt-controller@1 {
- compatible = "ti,omap2-intc";
- interrupt-controller;
- #interrupt-cells = <1>;
- ti,intc-size = <96>;

-All TI OMAP4/5 (and their derivatives) an interrupt controller that
-routes interrupts to the GIC, and also serves as a wakeup source. It
-is also referred to as "WUGEN-MPU", hence the name of the binding.
-
-Required properties:
-
-- compatible : should contain at least "ti,omap4-wugen-mpu" or
- "ti,omap5-wugen-mpu"
-- reg : Specifies base physical address and size of the registers.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source. The value must be 3.
-
-Notes:
-
-- Because this HW ultimately routes interrupts to the GIC, the
- interrupt specifier must be that of the GIC.
-- Only SPIs can use the WUGEN as an interrupt parent. SGIs and PPIs
- are explicitly forbidden.

-* QCOM IOMMU
-
-The MSM IOMMU is an implementation compatible with the ARM VMSA short
-descriptor page tables. It provides address translation for bus masters outside
-of the CPU, each connected to the IOMMU through a port called micro-TLB.
-
-Required Properties:
-
- - compatible: Must contain "qcom,apq8064-iommu".
- - reg: Base address and size of the IOMMU registers.
- - interrupts: Specifiers for the MMU fault interrupts. For instances that
- support secure mode two interrupts must be specified, for non-secure and
- secure mode, in that order. For instances that don't support secure mode a
- single interrupt must be specified.
- - #iommu-cells: The number of cells needed to specify the stream id. This
- is always 1.
- - qcom,ncb: The total number of context banks in the IOMMU.
- - clocks : List of clocks to be used during SMMU register access. See
- Documentation/devicetree/bindings/clock/clock-bindings.txt
- for information about the format. For each clock specified
- here, there must be a corresponding entry in clock-names
- (see below).
-
- - clock-names : List of clock names corresponding to the clocks specified in
- the "clocks" property (above).
- Should be "smmu_pclk" for specifying the interface clock
- required for iommu's register accesses.
- Should be "smmu_clk" for specifying the functional clock
- required by iommu for bus accesses.
-
-Each bus master connected to an IOMMU must reference the IOMMU in its device
-node with the following property:
-
- - iommus: A reference to the IOMMU in multiple cells. The first cell is a
- phandle to the IOMMU and the second cell is the stream id.
- A single master device can be connected to more than one iommu
- and multiple contexts in each of the iommu. So multiple entries
- are required to list all the iommus and the stream ids that the
- master is connected to.
-
-Example: mdp iommu and its bus master
-

-* QCOM IOMMU v1 Implementation
-
-Qualcomm "B" family devices which are not compatible with arm-smmu have
-a similar looking IOMMU but without access to the global register space,
-and optionally requiring additional configuration to route context irqs
-to non-secure vs secure interrupt line.
-
-** Required properties:
-
-- compatible : Should be one of:
-
- "qcom,msm8916-iommu"
- "qcom,msm8953-iommu"
-
- Followed by "qcom,msm-iommu-v1".
-
-- clock-names : Should be a pair of "iface" (required for IOMMUs
- register group access) and "bus" (required for
- the IOMMUs underlying bus access).
-
-- clocks : Phandles for respective clocks described by
- clock-names.
-
-- #address-cells : must be 1.
-
-- #size-cells : must be 1.
-
-- #iommu-cells : Must be 1. Index identifies the context-bank #.
-
-- ranges : Base address and size of the iommu context banks.
-
-- qcom,iommu-secure-id : secure-id.
-
-- List of sub-nodes, one per translation context bank. Each sub-node
- has the following required properties:
-
- - compatible : Should be one of:
- - "qcom,msm-iommu-v1-ns" : non-secure context bank
- - "qcom,msm-iommu-v1-sec" : secure context bank
- - reg : Base address and size of context bank within the iommu
- - interrupts : The context fault irq.
-
-** Optional properties:
-
-- reg : Base address and size of the SMMU local base, should
- be only specified if the iommu requires configuration
- for routing of context bank irq's to secure vs non-
- secure lines. (Ie. if the iommu contains secure
- context banks)

+maintainers:

+
+description: |
+ The RISC-V IOMMU provides memory address translation and isolation for
+ input and output devices, supporting per-device translation context,
+ shared process address spaces including the ATS and PRI components of
+ the PCIe specification, two stage address translation and MSI remapping.
+ It supports identical translation table format to the RISC-V address
+ translation tables with page level access and protection attributes.
+ Hardware uses in-memory command and fault reporting queues with wired
+ interrupt or MSI notifications.
+
+ Visit https://github.com/riscv-non-isa/riscv-iommu for more details.
+
+ For information on assigning RISC-V IOMMU to its peripheral devices,
+ see generic IOMMU bindings.
+
+properties:
+ # For PCIe IOMMU hardware compatible property should contain the vendor
+ # and device ID according to the PCI Bus Binding specification.
+ # Since PCI provides built-in identification methods, compatible is not

+ # should be specified along with 'reg' property providing MMIO location.

+
+description: |
+ The TPS61310/TPS61311 is a flash LED driver with I2C interface.
+ Its power stage is capable of supplying a maximum total current of roughly 1500mA.
+ The TPS6131x provides three constant-current sinks, capable of sinking
+ up to 2 x 400mA (LED1 and LED3) and 800mA (LED2) in flash mode.
+ In torch mode, each sink (LED1, LED2, LED3) supports currents up to 175mA.
+ Since the three current sinks share most of the control components such as
+ flash timer, control logic, safety timer and the operating mode, they cannot
+ be used completely independently of each other. Therefore, only one LED is
+ supported, but the current sinks can be combined accordingly.

+ - Cristian Marussi <cristian.marussi@arm.com>
+
+description: |
+ The Arm Message Handling Unit (MHU) Version 3 is a mailbox controller that
+ enables unidirectional communications with remote processors through various
+ possible transport protocols.
+ The controller can optionally support a varying number of extensions that, in
+ turn, enable different kinds of transport to be used for communication.
+ Number, type and characteristics of each supported extension can be discovered
+ dynamically at runtime.
+
+ Given the unidirectional nature of the controller, an MHUv3 mailbox controller
+ is composed of a MHU Sender (MHUS) containing a PostBox (PBX) block and a MHU
+ Receiver (MHUR) containing a MailBox (MBX) block, where
+
+ PBX is used to
+ - Configure the MHU
+ - Send Transfers to the Receiver
+ - Optionally receive acknowledgment of a Transfer from the Receiver
+
+ MBX is used to
+ - Configure the MHU
+ - Receive Transfers from the Sender
+ - Optionally acknowledge Transfers sent by the Sender
+
+ Both PBX and MBX need to be present and defined in the DT description if you
+ need to establish a bidirectional communication, since you will have to
+ acquire two distinct unidirectional channels, one for each block.
+
+ As a consequence both blocks needs to be represented separately and specified
+ as distinct DT nodes in order to properly describe their resources.
+
+ Note that, though, thanks to the runtime discoverability, there is no need to
+ identify the type of blocks with distinct compatibles.
+
+ Following are the MHUv3 possible extensions.
+
+ - Doorbell Extension (DBE): DBE defines a type of channel called a Doorbell
+ Channel (DBCH). DBCH enables a single bit Transfer to be sent from the
+ Sender to Receiver. The Transfer indicates that an event has occurred.
+ When DBE is implemented, the number of DBCHs that an implementation of the
+ MHU can support is between 1 and 128, numbered starting from 0 in ascending
+ order and discoverable at run-time.
+ Each DBCH contains 32 individual fields, referred to as flags, each of which
+ can be used independently. It is possible for the Sender to send multiple
+ Transfers at once using a single DBCH, so long as each Transfer uses
+ a different flag in the DBCH.
+ Optionally, data may be transmitted through an out-of-band shared memory
+ region, wherein the MHU Doorbell is used strictly as an interrupt generation
+ mechanism, but this is out of the scope of these bindings.
+
+ - FastChannel Extension (FCE): FCE defines a type of channel called a Fast
+ Channel (FCH). FCH is intended for lower overhead communication between
+ Sender and Receiver at the expense of determinism. An FCH allows the Sender
+ to update the channel value at any time, regardless of whether the previous
+ value has been seen by the Receiver. When the Receiver reads the channel's
+ content it gets the last value written to the channel.
+ FCH is considered lossy in nature, and means that the Sender has no way of
+ knowing if, or when, the Receiver will act on the Transfer.
+ FCHs are expected to behave as RAM which generates interrupts when writes
+ occur to the locations within the RAM.
+ When FCE is implemented, the number of FCHs that an implementation of the
+ MHU can support is between 1-1024, if the FastChannel word-size is 32-bits,
+ or between 1-512, when the FastChannel word-size is 64-bits.
+ FCHs are numbered from 0 in ascending order.
+ Note that the number of FCHs and the word-size are implementation defined,
+ not configurable but discoverable at run-time.
+ Optionally, data may be transmitted through an out-of-band shared memory
+ region, wherein the MHU FastChannel is used as an interrupt generation
+ mechanism which carries also a pointer to such out-of-band data, but this
+ is out of the scope of these bindings.
+
+ - FIFO Extension (FE): FE defines a Channel type called a FIFO Channel (FFCH).
+ FFCH allows a Sender to send
+ - Multiple Transfers to the Receiver without having to wait for the
+ previous Transfer to be acknowledged by the Receiver, as long as the
+ FIFO has room for the Transfer.
+ - Transfers which require the Receiver to provide acknowledgment.
+ - Transfers which have in-band payload.
+ In all cases, the data is guaranteed to be observed by the Receiver in the
+ same order which the Sender sent it.
+ When FE is implemented, the number of FFCHs that an implementation of the
+ MHU can support is between 1 and 64, numbered starting from 0 in ascending
+ order. The number of FFCHs, their depth (same for all implemented FFCHs) and
+ the access-granularity are implementation defined, not configurable but
+ discoverable at run-time.
+ Optionally, additional data may be transmitted through an out-of-band shared
+ memory region, wherein the MHU FIFO is used to transmit, in order, a small
+ part of the payload (like a header) and a reference to the shared memory
+ area holding the remaining, bigger, chunk of the payload, but this is out of
+ the scope of these bindings.

+ mechanism that allows processors to send and receive messages through
+ dedicated channels.
+
+ The mailbox's tx/rx are independent, meaning that one processor can send a
+ message while another processor is receiving a message simultaneously.
+ There are 4 channels available for both tx and rx operations. Each channel
+ has a FIFO buffer that can hold messages of a fixed size (32 bytes in this
+ case).
+
+ The mailbox controller also supports interrupt generation, allowing
+ processors to notify each other when a message is available or when an event
+ occurs.

-Broadcom FlexRM Ring Manager
-============================
-The Broadcom FlexRM ring manager provides a set of rings which can be
-used to submit work to offload engines. An SoC may have multiple FlexRM
-hardware blocks. There is one device tree entry per FlexRM block. The
-FlexRM driver will create a mailbox-controller instance for given FlexRM
-hardware block where each mailbox channel is a separate FlexRM ring.
-
-Required properties:
---------------------
-- compatible: Should be "brcm,iproc-flexrm-mbox"
-- reg: Specifies base physical address and size of the FlexRM
- ring registers
-- msi-parent: Phandles (and potential Device IDs) to MSI controllers
- The FlexRM engine will send MSIs (instead of wired
- interrupts) to CPU. There is one MSI for each FlexRM ring.
- Refer devicetree/bindings/interrupt-controller/msi.txt
-- #mbox-cells: Specifies the number of cells needed to encode a mailbox
- channel. This should be 3.
-
- The 1st cell is the mailbox channel number.
-
- The 2nd cell contains MSI completion threshold. This is the
- number of completion messages for which FlexRM will inject
- one MSI interrupt to CPU.
-
- The 3nd cell contains MSI timer value representing time for
- which FlexRM will wait to accumulate N completion messages
- where N is the value specified by 2nd cell above. If FlexRM
- does not get required number of completion messages in time
- specified by this cell then it will inject one MSI interrupt
- to CPU provided atleast one completion message is available.
-
-Optional properties:
---------------------
-- dma-coherent: Present if DMA operations made by the FlexRM engine (such
- as DMA descriptor access, access to buffers pointed by DMA
- descriptors and read/write pointer updates to DDR) are
- cache coherent with the CPU.
-
-Example:
---------
-crypto_mbox: mbox@67000000 {
- compatible = "brcm,iproc-flexrm-mbox";
- reg = <0x67000000 0x200000>;
- msi-parent = <&gic_its 0x7f00>;
- #mbox-cells = <3>;
-};
-
-crypto@672c0000 {
- compatible = "brcm,spu2-v2-crypto";
- reg = <0x672c0000 0x1000>;
- mboxes = <&crypto_mbox 0 0x1 0xffff>,
- <&crypto_mbox 1 0x1 0xffff>,
- <&crypto_mbox 16 0x1 0xffff>,
- <&crypto_mbox 17 0x1 0xffff>,
- <&crypto_mbox 30 0x1 0xffff>,
- <&crypto_mbox 31 0x1 0xffff>;
-};

+description:
+ The Cixtech mailbox controller, used in the Cixtech Sky1 SoC,
+ is used for message transmission between multiple processors
+ within the SoC, such as the AP, PM, audio DSP, SensorHub MCU,
+ and others
+
+ Each Cixtech mailbox controller is unidirectional, so they are
+ typically used in pairs-one for receiving and one for transmitting.
+
+ Each Cixtech mailbox supports 11 channels with different transmission modes
+ channel 0-7 - Fast channel with 32bit transmit register and IRQ support
+ channel 8 - Doorbell mode,using the mailbox as an interrupt-generating
+ mechanism.
+ channel 9 - Fifo based channel with 32*32bit depth fifo and IRQ support
+ channel 10 - Reg based channel with 32*32bit transmit register and
+ Doorbell+transmit acknowledgment IRQ support
+
+ In the CIX Sky1 SoC use case, there are 4 pairs of mailbox controllers
+ AP <--> PM - using Doorbell transfer mode
+ AP <--> SE - using REG transfer mode
+ AP <--> DSP - using FIFO transfer mode
+ AP <--> SensorHub - using FIFO transfer mode

+title: MediaTek Global Command Engine Common Properties
+
+maintainers:

+
+description:
+ The Global Command Engine (GCE) is an instruction based, multi-threaded,
+ single-core command dispatcher for MediaTek hardware. The Command Queue
+ (CMDQ) mailbox driver is a driver for GCE, implemented using the Linux
+ mailbox framework. It is used to receive messages from mailbox consumers
+ and configure GCE to execute the specified instruction set in the message.
+ We use mediatek,gce-mailbox.yaml to define the properties for CMDQ mailbox
+ driver. A device driver that uses the CMDQ driver to configure its hardware
+ registers is a mailbox consumer. The mailbox consumer can request a mailbox
+ channel corresponding to a GCE hardware thread to send a message, specifying
+ that the GCE thread to configure its hardware. The mailbox provider can also
+ reserve a mailbox channel to configure GCE hardware register by the specific
+ GCE thread. This binding defines the common GCE properties for both mailbox
+ provider and consumers.
+
+properties:
+ mediatek,gce-events:
+ description:
+ GCE has an event table in SRAM, consisting of 1024 event IDs (0~1023).
+ Each event ID has a boolean event value with the default value 0.
+ The property mediatek,gce-events is used to obtain the event IDs.
+ Some gce-events are hardware-bound and cannot be changed by software.
+ For instance, in MT8195, when VDO0_MUTEX is stream done, VDO_MUTEX will
+ send an event signal to GCE, setting the value of event ID 597 to 1.
+ Similarly, in MT8188, the value of event ID 574 will be set to 1 when
+ VOD0_MUTEX is stream done.
+ On the other hand, some gce-events are not hardware-bound and can be
+ changed by software. For example, in MT8188, we can set the value of
+ event ID 855, which is not bound to any hardware, to 1 when the driver
+ in the secure world completes a task. However, in MT8195, event ID 855
+ is already bound to VDEC_LAT1, so we need to select another event ID to
+ achieve the same purpose. This event ID can be any ID that is not bound
+ to any hardware and is not yet used in any software driver.
+ To determine if the event ID is bound to the hardware or used by a
+ software driver, refer to the GCE header
+ include/dt-bindings/gce/<chip>-gce.h of each chip.

-The APM X-Gene SLIMpro mailbox is used to communicate messages between
-the ARM64 processors and the Cortex M3 (dubbed SLIMpro). It uses a simple
-interrupt based door bell mechanism and can exchange simple messages using the
-internal registers.
-
-There are total of 8 interrupts in this mailbox. Each used for an individual
-door bell (or mailbox channel).
-
-Required properties:
-- compatible: Should be as "apm,xgene-slimpro-mbox".
-
-- reg: Contains the mailbox register address range.
-
-- interrupts: 8 interrupts must be from 0 to 7, interrupt 0 define the
- the interrupt for mailbox channel 0 and interrupt 1 for
- mailbox channel 1 and so likewise for the reminder.
-
-- #mbox-cells: only one to specify the mailbox channel number.

-Example:
-
-Mailbox Node:
- mailbox: mailbox@10540000 {

-Cadence MIPI-CSI2 RX controller
-===============================
-
-The Cadence MIPI-CSI2 RX controller is a CSI-2 bridge supporting up to 4 CSI
-lanes in input, and 4 different pixel streams in output.
-
-Required properties:
- - compatible: must be set to "cdns,csi2rx" and an SoC-specific compatible
- - reg: base address and size of the memory mapped region
- - clocks: phandles to the clocks driving the controller
- - clock-names: must contain:
- * sys_clk: main clock
- * p_clk: register bank clock
- * pixel_if[0-3]_clk: pixel stream output clock, one for each stream
- implemented in hardware, between 0 and 3
-
-Optional properties:
- - phys: phandle to the external D-PHY, phy-names must be provided
- - phy-names: must contain "dphy", if the implementation uses an
- external D-PHY
-
-Required subnodes:
- - ports: A ports node with one port child node per device input and output
- port, in accordance with the video interface bindings defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt. The
- port nodes are numbered as follows:
-
- Port Description
- -----------------------------
- 0 CSI-2 input
- 1 Stream 0 output
- 2 Stream 1 output
- 3 Stream 2 output
- 4 Stream 3 output
-
- The stream output port nodes are optional if they are not
- connected to anything at the hardware level or implemented
- in the design.Since there is only one endpoint per port,
- the endpoints are not numbered.
-
-
-Example:
-
-csi2rx: csi-bridge@0d060000 {
- compatible = "cdns,csi2rx";
- reg = <0x0d060000 0x1000>;
- clocks = <&byteclock>, <&byteclock>
- <&coreclock>, <&coreclock>,
- <&coreclock>, <&coreclock>;
- clock-names = "sys_clk", "p_clk",
- "pixel_if0_clk", "pixel_if1_clk",
- "pixel_if2_clk", "pixel_if3_clk";
-
- ports {
- #address-cells = <1>;
- #size-cells = <0>;
-
- port@0 {
- reg = <0>;
-
- csi2rx_in_sensor: endpoint {
- remote-endpoint = <&sensor_out_csi2rx>;
- clock-lanes = <0>;
- data-lanes = <1 2>;
- };
- };
-
- port@1 {
- reg = <1>;
-
- csi2rx_out_grabber0: endpoint {
- remote-endpoint = <&grabber0_in_csi2rx>;
- };
- };
-
- port@2 {
- reg = <2>;
-
- csi2rx_out_grabber1: endpoint {
- remote-endpoint = <&grabber1_in_csi2rx>;
- };
- };
-
- port@3 {
- reg = <3>;
-
- csi2rx_out_grabber2: endpoint {
- remote-endpoint = <&grabber2_in_csi2rx>;
- };
- };
-
- port@4 {

-Freescale Video Data Order Adapter
-==================================
-
-The Video Data Order Adapter (VDOA) is present on the i.MX6q. Its sole purpose
-is to reorder video data from the macroblock tiled order produced by the CODA
-960 VPU to the conventional raster-scan order for scanout.
-
-Required properties:
-- compatible: must be "fsl,imx6q-vdoa"
-- reg: the register base and size for the device registers
-- interrupts: the VDOA interrupt
-- clocks: the vdoa clock
-
-Example:
-
-vdoa@21e4000 {
- compatible = "fsl,imx6q-vdoa";
- reg = <0x021e4000 0x4000>;
- interrupts = <0 18 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&clks IMX6QDL_CLK_VDOA>;

+ The MAX96714 deserializer converts GMSL2 serial inputs into MIPI
+ CSI-2 D-PHY formatted output. The device allows the GMSL2 link to

+ interconnects. The device cans operate in pixel or tunnel mode. In pixel mode
+ the MAX96714 can select individual video stream, while the tunnel mode forward all
+ the MIPI data received by the serializer.
+
+ The GMSL2 serial link operates at a fixed rate of 3Gbps or 6Gbps in the
+ forward direction and 187.5Mbps in the reverse direction.
+ MAX96714F only supports a fixed rate of 3Gbps in the forward direction.

+ - RGB 12bit per color (36 bits total): R[11:0] B[11:0] G[11:0]
+ - YUV444 12bit per color (36 bits total): Y[11:0] Cb[11:0] Cr[11:0]

+ - YUV422 BT656 12bit per component (12 bits total): YCbCr[11:0] (2-cycles)
+
+ The Video port output pins are mapped via 4-bit 'pin groups' allowing
+ for a variety of connection possibilities including swapping pin order within
+ pin groups. The video_portcfg device-tree property consists of register mapping
+ pairs which map a chip-specific VP output register to a 4-bit pin group. If
+ the pin group needs to be bit-swapped you can use the *_S pin-group defines.

-The TDA19973 Video port output pins can be used as follows:
- - RGB 12bit per color (36 bits total): R[11:0] B[11:0] G[11:0]
- - YUV444 12bit per color (36 bits total): Y[11:0] Cb[11:0] Cr[11:0]
- - YUV422 semi-planar 12bit per component (24 bits total): Y[11:0] CbCr[11:0]
- - YUV422 BT656 12bit per component (12 bits total): YCbCr[11:0] (2-cycles)
-
-The Video port output pins are mapped via 4-bit 'pin groups' allowing
-for a variety of connection possibilities including swapping pin order within
-pin groups. The video_portcfg device-tree property consists of register mapping
-pairs which map a chip-specific VP output register to a 4-bit pin group. If
-the pin group needs to be bit-swapped you can use the *_S pin-group defines.
-
-Required Properties:
- - compatible :
- - "nxp,tda19971" for the TDA19971
- - "nxp,tda19973" for the TDA19973
- - reg : I2C slave address
- - interrupts : The interrupt number
- - DOVDD-supply : Digital I/O supply
- - DVDD-supply : Digital Core supply
- - AVDD-supply : Analog supply
- - nxp,vidout-portcfg : array of pairs mapping VP output pins to pin groups.
-
-Optional Properties:
- - nxp,audout-format : DAI bus format: "i2s" or "spdif".
- - nxp,audout-width : width of audio output data bus (1-4).
- - nxp,audout-layout : data layout (0=AP0 used, 1=AP0/AP1/AP2/AP3 used).
- - nxp,audout-mclk-fs : Multiplication factor between stream rate and codec
- mclk.
-
-The port node shall contain one endpoint child node for its digital
-output video port, in accordance with the video interface bindings defined in
-Documentation/devicetree/bindings/media/video-interfaces.txt.
-
-Optional Endpoint Properties:
- The following three properties are defined in video-interfaces.txt and
- are valid for the output parallel bus endpoint:
- - hsync-active: Horizontal synchronization polarity. Defaults to active high.
- - vsync-active: Vertical synchronization polarity. Defaults to active high.
- - data-active: Data polarity. Defaults to active high.

-Freescale i.MX Media Video Device
-=================================
-
-Video Media Controller node
----------------------------
-
-This is the media controller node for video capture support. It is a
-virtual device that lists the camera serial interface nodes that the
-media device will control.
-
-Required properties:
-- compatible : "fsl,imx-capture-subsystem";
-- ports : Should contain a list of phandles pointing to camera
- sensor interface ports of IPU devices
-
-example:
-
-capture-subsystem {
- compatible = "fsl,imx-capture-subsystem";
- ports = <&ipu1_csi0>, <&ipu1_csi1>;
-};
-
-
-mipi_csi2 node
---------------
-
-This is the device node for the MIPI CSI-2 Receiver core in the i.MX
-SoC. This is a Synopsys Designware MIPI CSI-2 host controller core
-combined with a D-PHY core mixed into the same register block. In
-addition this device consists of an i.MX-specific "CSI2IPU gasket"
-glue logic, also controlled from the same register block. The CSI2IPU
-gasket demultiplexes the four virtual channel streams from the host
-controller's 32-bit output image bus onto four 16-bit parallel busses
-to the i.MX IPU CSIs.
-
-Required properties:
-- compatible : "fsl,imx6-mipi-csi2";
-- reg : physical base address and length of the register set;
-- clocks : the MIPI CSI-2 receiver requires three clocks: hsi_tx
- (the D-PHY clock), video_27m (D-PHY PLL reference
- clock), and eim_podf;
-- clock-names : must contain "dphy", "ref", "pix";
-- port@* : five port nodes must exist, containing endpoints
- connecting to the source and sink devices according to
- of_graph bindings. The first port is an input port,
- connecting with a MIPI CSI-2 source, and ports 1
- through 4 are output ports connecting with parallel
- bus sink endpoint nodes and correspond to the four
- MIPI CSI-2 virtual channel outputs.
-
-Optional properties:
-- interrupts : must contain two level-triggered interrupts,
- in order: 100 and 101;

-
- As above, there are parent and child devices, child mean each hardware. The child device
- controls the information of each hardware independent which include clk/power/irq.
-
- There are two workqueues in parent device: lat workqueue and core workqueue. They are used
- to lat and core hardware deocder. Lat workqueue need to get input bitstream and lat buffer,
- then enable lat to decode, writing the result to lat buffer, dislabe hardware when lat decode
- done. Core workqueue need to get lat buffer and output buffer, then enable core to decode,
- writing the result to output buffer, disable hardware when core decode done. These two
- hardwares will decode each frame cyclically.
-
- For the smi common may not the same for each hardware, can't combine all hardware in one node,
- or leading to iommu fault when access dram data.
-
- Lat soc is a hardware which is related with some larb(local arbiter) ports. For mt8195
- platform, there are some ports like RDMA, UFO in lat soc larb, need to enable its power and
- clock when lat start to work, don't have interrupt.

+ MediaTek Video Decode Accelerator is the video decoding hardware present in
+ MediaTek SoCs that supports high-resolution decoding functionalities.
+ It consists of parent and child nodes.
+
+ The decoder hardware block diagram is shown below:
+
+ +------------------------------------------------+------------------------------+
+ | | |
+ | input -> LAT-SoC HW -> LAT HW -> LAT buffer --|--> Core HW -> output buffer |
+ | || || | || |
+ +--------------||-----------||-------------------+-------||---------------------+

+ | enable/disable |
+ | clk power irq iommu |
+ | (lat/lat-soc/core0/core1) |
+ +-------------------------------------------------------------+
+
+ The child nodes represent the individual hardware blocks within the decoding
+ pipeline, such as LAT-SoC, LAT and Core.
+ Each child node is responsible for managing the dedicated resources of the
+ hardware, such as clocks, power domains, interrupts and IOMMUs.
+
+ The parent node is a central point of control for the child nodes.
+ It identifies the specific video decoding pipeline architecture used by the
+ SoC, manages the shared resources like workqueues and platform data, and
+ handles V4L2 API calls on behalf of the underlying hardware.
+
+ The parent utilizes two workqueues to manage the decoding process.
+ 1. LAT Workqueue, for LAT-SoC and LAT decoder:
+ Its workers take input bitstream and LAT buffer, enable the hardware for
+ decoding tasks, write the result to LAT buffer, and disable the hardware
+ after the LAT decoding is done.
+ 2. Core Workqueue, for Core decoder:
+ Its workers take LAT buffer and output buffer, enable the hardware for
+ decoding tasks, write the result to output buffer, and disable the hardware
+ after the Core decoding is done.
+
+ These hardware decode each frame cyclically.
+
+ The hardware might be associated with different SMI-common devices.
+ To prevent IOMMU faults during DRAM access in such cases, each hardware with
+ the unique SMI-common device must be placed under a separate parent node in
+ the device tree.
+
+ LAT-SoC refers to another hardware block that connected to additional LARB
+ (local arbiter) ports, such as RDMA and UFO.
+ It requires independent power and clock control to work with LAT decoder, and
+ it doesn't have a dedicated interrupt.
+
+ The used video decoding pipeline architecture across various Mediatek SoC:
+ MT8195: LAT-SoC + LAT + Core
+ MT8192: LAT + Core
+ MT8188: LAT + Core

-* Samsung Multi Format Codec (MFC)
-
-Multi Format Codec (MFC) is the IP present in Samsung SoCs which
-supports high resolution decoding and encoding functionalities.
-The MFC device driver is a v4l2 driver which can encode/decode
-video raw/elementary streams and has support for all popular
-video codecs.
-
-Required properties:
- - compatible : value should be either one among the following
- (a) "samsung,mfc-v5" for MFC v5 present in Exynos4 SoCs
- (b) "samsung,mfc-v6" for MFC v6 present in Exynos5 SoCs
- (c) "samsung,exynos3250-mfc", "samsung,mfc-v7" for MFC v7
- present in Exynos3250 SoC
- (d) "samsung,mfc-v7" for MFC v7 present in Exynos5420 SoC
- (e) "samsung,mfc-v8" for MFC v8 present in Exynos5800 SoC
- (f) "samsung,exynos5433-mfc" for MFC v8 present in Exynos5433 SoC
- (g) "samsung,mfc-v10" for MFC v10 present in Exynos7880 SoC
-
- - reg : Physical base address of the IP registers and length of memory
- mapped region.
-
- - interrupts : MFC interrupt number to the CPU.
- - clocks : from common clock binding: handle to mfc clock.
- - clock-names : from common clock binding: must contain "mfc",
- corresponding to entry in the clocks property.
-
-Optional properties:
- - power-domains : power-domain property defined with a phandle
- to respective power domain.
- - memory-region : from reserved memory binding: phandles to two reserved
- memory regions, first is for "left" mfc memory bus interfaces,
- second if for the "right" mfc memory bus, used when no SYSMMU
- support is available; used only by MFC v5 present in Exynos4 SoCs
-
-Obsolete properties:
- - samsung,mfc-r, samsung,mfc-l : support removed, please use memory-region
- property instead
-
-
-Example:
-SoC specific DT entry:
-
-mfc: codec@13400000 {
- compatible = "samsung,mfc-v5";
- reg = <0x13400000 0x10000>;
- interrupts = <0 94 0>;
- power-domains = <&pd_mfc>;
- clocks = <&clock 273>;
- clock-names = "mfc";
-};
-
-Reserved memory specific DT entry for given board (see reserved memory binding
-for more information):
-
-reserved-memory {
- #address-cells = <1>;
- #size-cells = <1>;
- ranges;
-
- mfc_left: region@51000000 {
- compatible = "shared-dma-pool";
- no-map;
- reg = <0x51000000 0x800000>;
- };
-
- mfc_right: region@43000000 {
- compatible = "shared-dma-pool";
- no-map;
- reg = <0x43000000 0x800000>;
- };
-};
-
-Board specific DT entry:
-
-codec@13400000 {
- memory-region = <&mfc_left>, <&mfc_right>;
-};

-Samsung S5P/Exynos SoC Camera Subsystem (FIMC)
-----------------------------------------------
-
-The S5P/Exynos SoC Camera subsystem comprises of multiple sub-devices
-represented by separate device tree nodes. Currently this includes: FIMC (in
-the S5P SoCs series known as CAMIF), MIPI CSIS, FIMC-LITE and FIMC-IS (ISP).
-
-The sub-subdevices are defined as child nodes of the common 'camera' node which
-also includes common properties of the whole subsystem not really specific to
-any single sub-device, like common camera port pins or the CAMCLK clock outputs
-for external image sensors attached to an SoC.
-
-Common 'camera' node
---------------------
-
-Required properties:
-
-- compatible: must be "samsung,fimc", "simple-bus"
-- clocks: list of clock specifiers, corresponding to entries in
- the clock-names property;
-- clock-names : must contain "sclk_cam0", "sclk_cam1", "pxl_async0",
- "pxl_async1" entries, matching entries in the clocks property.
-
-- #clock-cells: from the common clock bindings (../clock/clock-bindings.txt),
- must be 1. A clock provider is associated with the 'camera' node and it should
- be referenced by external sensors that use clocks provided by the SoC on
- CAM_*_CLKOUT pins. The clock specifier cell stores an index of a clock.
- The indices are 0, 1 for CAM_A_CLKOUT, CAM_B_CLKOUT clocks respectively.
-
-- clock-output-names: from the common clock bindings, should contain names of
- clocks registered by the camera subsystem corresponding to CAM_A_CLKOUT,
- CAM_B_CLKOUT output clocks respectively.
-
-The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
-to define a required pinctrl state named "default" and optional pinctrl states:
-"idle", "active-a", active-b". These optional states can be used to switch the
-camera port pinmux at runtime. The "idle" state should configure both the camera
-ports A and B into high impedance state, especially the CAMCLK clock output
-should be inactive. For the "active-a" state the camera port A must be activated
-and the port B deactivated and for the state "active-b" it should be the other
-way around.
-
-The 'camera' node must include at least one 'fimc' child node.
-
-
-'fimc' device nodes
--------------------
-
-Required properties:
-
-- compatible: "samsung,s5pv210-fimc" for S5PV210, "samsung,exynos4210-fimc"
- for Exynos4210 and "samsung,exynos4212-fimc" for Exynos4x12 SoCs;
-- reg: physical base address and length of the registers set for the device;
-- interrupts: should contain FIMC interrupt;
-- clocks: list of clock specifiers, must contain an entry for each required
- entry in clock-names;
-- clock-names: must contain "fimc", "sclk_fimc" entries.
-- samsung,pix-limits: an array of maximum supported image sizes in pixels, for
- details refer to Table 2-1 in the S5PV210 SoC User Manual; The meaning of
- each cell is as follows:
- 0 - scaler input horizontal size,
- 1 - input horizontal size for the scaler bypassed,
- 2 - REAL_WIDTH without input rotation,
- 3 - REAL_HEIGHT with input rotation,
-- samsung,sysreg: a phandle to the SYSREG node.
-
-Each FIMC device should have an alias in the aliases node, in the form of
-fimc<n>, where <n> is an integer specifying the IP block instance.
-

-Samsung S5C73M3 8Mp camera ISP
-------------------------------
-
-The S5C73M3 camera ISP supports MIPI CSI-2 and parallel (ITU-R BT.656) video
-data busses. The I2C bus is the main control bus and additionally the SPI bus
-is used, mostly for transferring the firmware to and from the device. Two
-slave device nodes corresponding to these control bus interfaces are required
-and should be placed under respective bus controller nodes.

- configured to operate, in Hz; if this property is not
- specified default 24 MHz value will be used.
-
-The common video interfaces bindings (see video-interfaces.txt) should be used
-to specify link from the S5C73M3 to an external image data receiver. The S5C73M3
-device node should contain one 'port' child node with an 'endpoint' subnode for
-this purpose. The data link from a raw image sensor to the S5C73M3 can be
-similarly specified, but it is optional since the S5C73M3 ISP and a raw image
-sensor are usually inseparable and form a hybrid module.
-
-Following properties are valid for the endpoint node(s):
-
-endpoint subnode
-----------------
-
-- data-lanes : (optional) specifies MIPI CSI-2 data lanes as covered in

-STMicroelectronics STi c8sectpfe binding
-============================================
-
-This document describes the c8sectpfe device bindings that is used to get transport
-stream data into the SoC on the TS pins, and into DDR for further processing.
-
-It is typically used in conjunction with one or more demodulator and tuner devices
-which converts from the RF to digital domain. Demodulators and tuners are usually
-located on an external DVB frontend card connected to SoC TS input pins.
-
-Currently 7 TS input (tsin) channels are supported on the stih407 family SoC.
-
-Required properties (controller (parent) node):
-- compatible : Should be "stih407-c8sectpfe"
-
-- reg : Address and length of register sets for each device in
- "reg-names"
-
-- reg-names : The names of the register addresses corresponding to the
- registers filled in "reg":
- - c8sectpfe: c8sectpfe registers
- - c8sectpfe-ram: c8sectpfe internal sram
-
-- clocks : phandle list of c8sectpfe clocks
-- clock-names : should be "c8sectpfe"
-See: Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-- pinctrl-names : a pinctrl state named tsin%d-serial or tsin%d-parallel (where %d is tsin-num)
- must be defined for each tsin child node.
-- pinctrl-0 : phandle referencing pin configuration for this tsin configuration
-See: Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
-
-
-Required properties (tsin (child) node):
-
-- tsin-num : tsin id of the InputBlock (must be between 0 to 6)
-- i2c-bus : phandle to the I2C bus DT node which the demodulators & tuners on this tsin channel are connected.
-- reset-gpios : reset gpio for this tsin channel.
-
-Optional properties (tsin (child) node):
-
-- invert-ts-clk : Bool property to control sense of ts input clock (data stored on falling edge of clk).
-- serial-not-parallel : Bool property to configure input bus width (serial on ts_data<7>).
-- async-not-sync : Bool property to control if data is received in asynchronous mode
- (all bits/bytes with ts_valid or ts_packet asserted are valid).
-
-- dvb-card : Describes the NIM card connected to this tsin channel.
-
-Example:
-
-/* stih410 SoC b2120 + b2004a + stv0367-pll(NIMB) + stv0367-tda18212 (NIMA) DT example) */

+title: Qualcomm External Bus Interface 2 (EBI2)
+
+description: |
+ The EBI2 contains two peripheral blocks: XMEM and LCDC. The XMEM handles any
+ external memory (such as NAND or other memory-mapped peripherals) whereas
+ LCDC handles LCD displays.
+
+ As it says it connects devices to an external bus interface, meaning address
+ lines (up to 9 address lines so can only address 1KiB external memory space),
+ data lines (16 bits), OE (output enable), ADV (address valid, used on some
+ NOR flash memories), WE (write enable). This on top of 6 different chip selects
+ (CS0 thru CS5) so that in theory 6 different devices can be connected.
+
+ Apparently this bus is clocked at 64MHz. It has dedicated pins on the package
+ and the bus can only come out on these pins, however if some of the pins are
+ unused they can be left unconnected or remuxed to be used as GPIO or in some
+ cases other orthogonal functions as well.
+
+ Also CS1 and CS2 has -A and -B signals. Why they have that is unclear to me.
+
+ The chip selects have the following memory range assignments. This region of
+ memory is referred to as "Chip Peripheral SS FPB0" and is 168MB big.
+
+ Chip Select Physical address base
+ CS0 GPIO134 0x1a800000-0x1b000000 (8MB)
+ CS1 GPIO39 (A) / GPIO123 (B) 0x1b000000-0x1b800000 (8MB)
+ CS2 GPIO40 (A) / GPIO124 (B) 0x1b800000-0x1c000000 (8MB)
+ CS3 GPIO133 0x1d000000-0x25000000 (128 MB)
+ CS4 GPIO132 0x1c800000-0x1d000000 (8MB)
+ CS5 GPIO131 0x1c000000-0x1c800000 (8MB)
+
+ The APQ8060 Qualcomm Application Processor User Guide, 80-N7150-14 Rev. A,
+ August 6, 2012 contains some incomplete documentation of the EBI2.
+
+ FIXME: the manual mentions "write precharge cycles" and "precharge cycles".
+ We have not been able to figure out which bit fields these correspond to
+ in the hardware, or what valid values exist. The current hypothesis is that
+ this is something just used on the FAST chip selects and that the SLOW
+ chip selects are understood fully. There is also a "byte device enable"
+ flag somewhere for 8bit memories.
+
+ FIXME: The chipselects have SLOW and FAST configuration registers. It's a bit
+ unclear what this means, if they are mutually exclusive or can be used
+ together, or if some chip selects are hardwired to be FAST and others are SLOW
+ by design.
+
+ The XMEM registers are totally undocumented but could be partially decoded
+ because the Cypress AN49576 Antioch Westbridge apparently has suspiciously
+ similar register layout, see: http://www.cypress.com/file/105771/download

-AS3711 is an I2C PMIC from Austria MicroSystems with multiple DCDC and LDO power
-supplies, a battery charger and an RTC. So far only bindings for the two stepup
-DCDC converters are defined. Other DCDC and LDO supplies are configured, using
-standard regulator properties, they must belong to a sub-node, called
-"regulators" and be called "sd1" to "sd4" and "ldo1" to "ldo8." Stepup converter
-configuration should be placed in a subnode, called "backlight."
-
-Compulsory properties:
-- compatible : must be "ams,as3711"
-- reg : specifies the I2C address
-
-To use the SU1 converter as a backlight source the following two properties must
-be provided:
-- su1-dev : framebuffer phandle
-- su1-max-uA : maximum current
-
-To use the SU2 converter as a backlight source the following two properties must
-be provided:
-- su2-dev : framebuffer phandle
-- su1-max-uA : maximum current
-
-Additionally one of these properties must be provided to select the type of
-feedback used:
-- su2-feedback-voltage : voltage feedback is used
-- su2-feedback-curr1 : CURR1 input used for current feedback
-- su2-feedback-curr2 : CURR2 input used for current feedback
-- su2-feedback-curr3 : CURR3 input used for current feedback
-- su2-feedback-curr-auto: automatic current feedback selection
-
-and one of these to select the over-voltage protection pin
-- su2-fbprot-lx-sd4 : LX_SD4 is used for over-voltage protection
-- su2-fbprot-gpio2 : GPIO2 is used for over-voltage protection
-- su2-fbprot-gpio3 : GPIO3 is used for over-voltage protection
-- su2-fbprot-gpio4 : GPIO4 is used for over-voltage protection
-
-If "su2-feedback-curr-auto" is selected, one or more of the following properties
-have to be specified:
-- su2-auto-curr1 : use CURR1 input for current feedback
-- su2-auto-curr2 : use CURR2 input for current feedback
-- su2-auto-curr3 : use CURR3 input for current feedback

-title: Freescale i.MX8qm/qxp Control and Status Registers Module
-
-maintainers:
- - Liu Ying <victor.liu@nxp.com>
-
-description: |
- As a system controller, the Freescale i.MX8qm/qxp Control and Status
- Registers(CSR) module represents a set of miscellaneous registers of a
- specific subsystem. It may provide control and/or status report interfaces
- to a mix of standalone hardware devices within that subsystem. One typical
- use-case is for some other nodes to acquire a reference to the syscon node
- by phandle, and the other typical use-case is that the operating system
- should consider all subnodes of the CSR module as separate child devices.

-* Maxim MAX8998, National/TI LP3974 multi-function device
-
-The Maxim MAX8998 is a multi-function device which includes voltage/current
-regulators, real time clock, battery charging controller and several
-other sub-blocks. It is interfaced using an I2C interface. Each sub-block
-is addressed by the host system using different i2c slave address.
-
-PMIC sub-block
---------------
-
-The PMIC sub-block contains a number of voltage and current regulators,
-with controllable parameters and dynamic voltage scaling capability.
-In addition, it includes a real time clock and battery charging controller
-as well. It is accessible at I2C address 0x66.
-
-Required properties:
-- compatible: Should be one of the following:
- - "maxim,max8998" for Maxim MAX8998
- - "national,lp3974" or "ti,lp3974" for National/TI LP3974.
-- reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
-
-Optional properties:
-- interrupts: Interrupt specifiers for two interrupt sources.
- - First interrupt specifier is for main interrupt.
- - Second interrupt specifier is for power-on/-off interrupt.
-- max8998,pmic-buck1-dvs-gpios: GPIO specifiers for two host gpios used
- for buck 1 dvs. The format of the gpio specifier depends on the gpio
- controller.
-- max8998,pmic-buck2-dvs-gpio: GPIO specifier for host gpio used
- for buck 2 dvs. The format of the gpio specifier depends on the gpio
- controller.

-Spreadtrum SC27xx Power Management Integrated Circuit (PMIC)
-
-The Spreadtrum SC27xx series PMICs contain SC2720, SC2721, SC2723, SC2730
-and SC2731. The Spreadtrum PMIC belonging to SC27xx series integrates all
-mobile handset power management, audio codec, battery management and user
-interface support function in a single chip. It has 6 major functional
-blocks:
-- DCDCs to support CPU, memory.
-- LDOs to support both internal and external requirement.
-- Battery management system, such as charger, fuel gauge.
-- Audio codec.
-- User interface function, such as indicator, flash LED and so on.
-- IC level interface, such as power on/off control, RTC and typec and so on.
-
-Required properties:
-- compatible: Should be one of the following:
- "sprd,sc2720"
- "sprd,sc2721"
- "sprd,sc2723"
- "sprd,sc2730"
- "sprd,sc2731"
-- reg: The address of the device chip select, should be 0.
-- spi-max-frequency: Typically set to 26000000.
-- interrupts: The interrupt line the device is connected to.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: The number of cells to describe an PMIC IRQ, must be 2.
-- #address-cells: Child device offset number of cells, must be 1.
-- #size-cells: Child device size number of cells, must be 0.

+ System controller node represents a register region containing a set
+ of miscellaneous registers. The registers are not cohesive enough to
+ represent as any specific type of device. The typical use-case is
+ for some other node's driver, or platform-specific code, to acquire
+ a reference to the syscon node (e.g. by phandle, node path, or
+ search using a specific compatible value), interrogate the node (or
+ associated OS driver) to determine the location of the registers,
+ and access the registers directly.

-title: TI J721e System Controller Registers R/W
-
-description: |
- This represents the Control Module registers (CTRL_MMR0) on the SoC.
- System controller node represents a register region containing a set
- of miscellaneous registers. The registers are not cohesive enough to
- represent as any specific type of device. The typical use-case is
- for some other node's driver, or platform-specific code, to acquire
- a reference to the syscon node (e.g. by phandle, node path, or
- search using a specific compatible value), interrogate the node (or
- associated OS driver) to determine the location of the registers,
- and access the registers directly.

-Texas Instruments TWL family (twl4030) reset and power management module
-
-The power management module inside the TWL family provides several facilities
-to control the power resources, including power scripts. For now, the
-binding only supports the complete shutdown of the system after poweroff.
-
-Required properties:
-- compatible : must be one of the following
- "ti,twl4030-power"
- "ti,twl4030-power-reset"
- "ti,twl4030-power-idle"
- "ti,twl4030-power-idle-osc-off"
-
-The use of ti,twl4030-power-reset is recommended at least on
-3530 that needs a special configuration for warm reset to work.
-
-When using ti,twl4030-power-idle, the TI recommended configuration
-for idle modes is loaded to the tlw4030 PMIC.
-
-When using ti,twl4030-power-idle-osc-off, the TI recommended
-configuration is used with the external oscillator being shut
-down during off-idle. Note that this does not work on all boards
-depending on how the external oscillator is wired.
-
-Optional properties:
-
-- ti,system-power-controller: This indicates that TWL4030 is the
- power supply master of the system. With this flag, the chip will
- initiate an ACTIVE-to-OFF or SLEEP-to-OFF transition when the
- system poweroffs.

-The AST2500 supports a SW generated interrupt
-
-Required properties:
-- reg: address and length of the register for the device.
-- compatible: "aspeed,cvic" and one of:
- "aspeed,ast2400-cvic"
- or
- "aspeed,ast2500-cvic"
-
-- valid-sources: One cell, bitmap of supported sources for the implementation
-
-Optional properties;
-- copro-sw-interrupts: List of interrupt numbers that can be used as
- SW interrupts from the ARM to the coprocessor.
- (AST2500 only)

-Optional properties:
- - atmel,clk-from-rk-pin: bool property.
- - When SSC works in slave mode, according to the hardware design, the
- clock can get from TK pin, and also can get from RK pin. So, add
- this parameter to choose where the clock from.

-* Freescale Management Complex
-
-The Freescale Management Complex (fsl-mc) is a hardware resource
-manager that manages specialized hardware objects used in
-network-oriented packet processing applications. After the fsl-mc
-block is enabled, pools of hardware resources are available, such as
-queues, buffer pools, I/O interfaces. These resources are building
-blocks that can be used to create functional hardware objects/devices
-such as network interfaces, crypto accelerator instances, L2 switches,
-etc.
-
-For an overview of the DPAA2 architecture and fsl-mc bus see:
-Documentation/networking/device_drivers/ethernet/freescale/dpaa2/overview.rst
-
-As described in the above overview, all DPAA2 objects in a DPRC share the
-same hardware "isolation context" and a 10-bit value called an ICID
-(isolation context id) is expressed by the hardware to identify
-the requester.
-
-The generic 'iommus' property is insufficient to describe the relationship
-between ICIDs and IOMMUs, so an iommu-map property is used to define
-the set of possible ICIDs under a root DPRC and how they map to
-an IOMMU.
-
-For generic IOMMU bindings, see
-Documentation/devicetree/bindings/iommu/iommu.txt.
-
-For arm-smmu binding, see:
-Documentation/devicetree/bindings/iommu/arm,smmu.yaml.
-
-The MSI writes are accompanied by sideband data which is derived from the ICID.
-The msi-map property is used to associate the devices with both the ITS
-controller and the sideband data which accompanies the writes.
-
-For generic MSI bindings, see
-Documentation/devicetree/bindings/interrupt-controller/msi.txt.
-
-For GICv3 and GIC ITS bindings, see:
-Documentation/devicetree/bindings/interrupt-controller/arm,gic-v3.yaml.
-
-Required properties:
-
- - compatible
- Value type: <string>
- Definition: Must be "fsl,qoriq-mc". A Freescale Management Complex
- compatible with this binding must have Block Revision
- Registers BRR1 and BRR2 at offset 0x0BF8 and 0x0BFC in
- the MC control register region.
-
- - reg
- Value type: <prop-encoded-array>
- Definition: A standard property. Specifies one or two regions
- defining the MC's registers:
-
- -the first region is the command portal for the
- this machine and must always be present
-
- -the second region is the MC control registers. This
- region may not be present in some scenarios, such
- as in the device tree presented to a virtual machine.
-
- - ranges
- Value type: <prop-encoded-array>
- Definition: A standard property. Defines the mapping between the child
- MC address space and the parent system address space.
-
- The MC address space is defined by 3 components:
- <region type> <offset hi> <offset lo>
-
- Valid values for region type are
- 0x0 - MC portals
- 0x1 - QBMAN portals
-
- - #address-cells
- Value type: <u32>
- Definition: Must be 3. (see definition in 'ranges' property)
-
- - #size-cells
- Value type: <u32>
- Definition: Must be 1.
-
-Sub-nodes:
-
- The fsl-mc node may optionally have dpmac sub-nodes that describe
- the relationship between the Ethernet MACs which belong to the MC
- and the Ethernet PHYs on the system board.
-
- The dpmac nodes must be under a node named "dpmacs" which contains
- the following properties:
-
- - #address-cells
- Value type: <u32>
- Definition: Must be present if dpmac sub-nodes are defined and must
- have a value of 1.
-
- - #size-cells
- Value type: <u32>
- Definition: Must be present if dpmac sub-nodes are defined and must
- have a value of 0.
-
- These nodes must have the following properties:
-
- - compatible
- Value type: <string>
- Definition: Must be "fsl,qoriq-mc-dpmac".
-
- - reg
- Value type: <prop-encoded-array>
- Definition: Specifies the id of the dpmac.
-
- - phy-handle
- Value type: <phandle>
- Definition: Specifies the phandle to the PHY device node associated
- with the this dpmac.
-Optional properties:
-
-- iommu-map: Maps an ICID to an IOMMU and associated iommu-specifier

-
- The property is an arbitrary number of tuples of
- (icid-base,iommu,iommu-base,length).
-
- Any ICID i in the interval [icid-base, icid-base + length) is

-* Amlogic Meson6, Meson8 and Meson8b SDIO/MMC controller
-
-The highspeed MMC host controller on Amlogic SoCs provides an interface
-for MMC, SD, SDIO and SDHC types of memory cards.
-
-Supported maximum speeds are the ones of the eMMC standard 4.41 as well
-as the speed of SD standard 2.0.
-
-The hardware provides an internal "mux" which allows up to three slots
-to be controlled. Only one slot can be accessed at a time.
-
-Required properties:
- - compatible : must be one of
- - "amlogic,meson8-sdio"
- - "amlogic,meson8b-sdio"
- along with the generic "amlogic,meson-mx-sdio"
- - reg : mmc controller base registers
- - interrupts : mmc controller interrupt
- - #address-cells : must be 1
- - size-cells : must be 0
- - clocks : phandle to clock providers
- - clock-names : must contain "core" and "clkin"
-
-Required child nodes:
-A node for each slot provided by the MMC controller is required.
-NOTE: due to a driver limitation currently only one slot (= child node)
- is supported!
-
-Required properties on each child node (= slot):
- - compatible : must be "mmc-slot" (see mmc.txt within this directory)
- - reg : the slot (or "port") ID
-
-Optional properties on each child node (= slot):
- - bus-width : must be 1 or 4 (8-bit bus is not supported)
- - for cd and all other additional generic mmc parameters
- please refer to mmc.txt within this directory
-
-Examples:
- mmc@c1108c20 {
- compatible = "amlogic,meson8-sdio", "amlogic,meson-mx-sdio";

-* Atmel High Speed MultiMedia Card Interface
-
-This controller on atmel products provides an interface for MMC, SD and SDIO
-types of memory cards.
-
-This file documents differences between the core properties described
-by mmc.txt and the properties used by the atmel-mci driver.
-
-1) MCI node
-
-Required properties:
-- compatible: should be "atmel,hsmci"
-- #address-cells: should be one. The cell is the slot id.
-- #size-cells: should be zero.
-- at least one slot node
-- clock-names: tuple listing input clock names.
- Required elements: "mci_clk"
-- clocks: phandles to input clocks.
-
-The node contains child nodes for each slot that the platform uses
-
-Example MCI node:
-
-mmc0: mmc@f0008000 {
- compatible = "atmel,hsmci";
- reg = <0xf0008000 0x600>;
- interrupts = <12 4>;
- #address-cells = <1>;
- #size-cells = <0>;
- clock-names = "mci_clk";
- clocks = <&mci0_clk>;
-
- [ child node definitions...]
-};
-
-2) slot nodes
-
-Required properties:
-- reg: should contain the slot id.
-- bus-width: number of data lines connected to the controller
-
-Optional properties:
-- cd-gpios: specify GPIOs for card detection
-- cd-inverted: invert the value of external card detect gpio line
-- wp-gpios: specify GPIOs for write protection
-
-Example slot node:
-

+ # low." Therefore, using the "cd-inverted" property means, that the
+ # CD line is active high, i.e. it is high, when a card is
+ # inserted. Similar logic applies to the "wp-inverted" property.
+ #
+ # CD and WP lines can be implemented on the hardware in one of two
+ # ways: as GPIOs, specified in cd-gpios and wp-gpios properties, or
+ # as dedicated pins. Polarity of dedicated pins can be specified,
+ # using *-inverted properties. GPIO polarity can also be specified
+ # using the GPIO_ACTIVE_LOW flag. This creates an ambiguity in the
+ # latter case. We choose to use the XOR logic for GPIO CD and WP
+ # lines. This means, the two properties are "superimposed," for

- # of the "normal" and "inverted" line levels. We choose to follow
- # the SDHCI standard, which specifies both those lines as "active
- # low." Therefore, using the "cd-inverted" property means, that the
- # CD line is active high, i.e. it is high, when a card is
- # inserted. Similar logic applies to the "wp-inverted" property.
- #
- # CD and WP lines can be implemented on the hardware in one of two
- # ways: as GPIOs, specified in cd-gpios and wp-gpios properties, or
- # as dedicated pins. Polarity of dedicated pins can be specified,
- # using *-inverted properties. GPIO polarity can also be specified
- # using the GPIO_ACTIVE_LOW flag. This creates an ambiguity in the
- # latter case. We choose to use the XOR logic for GPIO CD and WP
- # lines. This means, the two properties are "superimposed," for
- # example leaving the GPIO_ACTIVE_LOW flag clear and specifying the
- # respective *-inverted property property results in a
- # double-inversion and actually means the "normal" line polarity is

-* Atmel SDHCI controller
-
-This file documents the differences between the core properties in
-Documentation/devicetree/bindings/mmc/mmc.txt and the properties used by the
-sdhci-of-at91 driver.
-
-Required properties:
-- compatible: Must be "atmel,sama5d2-sdhci" or "microchip,sam9x60-sdhci".
-- clocks: Phandlers to the clocks.
-- clock-names: Must be "hclock", "multclk", "baseclk" for
- "atmel,sama5d2-sdhci".
- Must be "hclock", "multclk" for "microchip,sam9x60-sdhci".
-
-Optional properties:
-- assigned-clocks: The same with "multclk".
-- assigned-clock-rates The rate of "multclk" in order to not rely on the
- gck configuration set by previous components.
-- microchip,sdcal-inverted: when present, polarity on the SDCAL SoC pin is
- inverted. The default polarity for this signal is described in the datasheet.
- For instance on SAMA5D2, the pin is usually tied to the GND with a resistor
- and a capacitor (see "SDMMC I/O Calibration" chapter).
-
-Example:
-

-* Spreadtrum SDHCI controller (sdhci-sprd)
-
-The Secure Digital (SD) Host controller on Spreadtrum SoCs provides an interface
-for MMC, SD and SDIO types of cards.
-
-This file documents differences between the core properties in mmc.txt
-and the properties used by the sdhci-sprd driver.
-
-Required properties:
-- compatible: Should contain "sprd,sdhci-r11".
-- reg: physical base address of the controller and length.
-- interrupts: Interrupts used by the SDHCI controller.
-- clocks: Should contain phandle for the clock feeding the SDHCI controller
-- clock-names: Should contain the following:
- "sdio" - SDIO source clock (required)
- "enable" - gate clock which used for enabling/disabling the device (required)
- "2x_enable" - gate clock controlling the device for some special platforms (optional)
-
-Optional properties:
-- assigned-clocks: the same with "sdio" clock
-- assigned-clock-parents: the default parent of "sdio" clock
-- pinctrl-names: should be "default", "state_uhs"
-- pinctrl-0: should contain default/high speed pin control
-- pinctrl-1: should contain uhs mode pin control
-
-PHY DLL delays are used to delay the data valid window, and align the window
-to sampling clock. PHY DLL delays can be configured by following properties,
-and each property contains 4 cells which are used to configure the clock data
-write line delay value, clock read command line delay value, clock read data
-positive edge delay value and clock read data negative edge delay value.
-Each cell's delay value unit is cycle of the PHY clock.
-
-- sprd,phy-delay-legacy: Delay value for legacy timing.
-- sprd,phy-delay-sd-highspeed: Delay value for SD high-speed timing.
-- sprd,phy-delay-sd-uhs-sdr50: Delay value for SD UHS SDR50 timing.
-- sprd,phy-delay-sd-uhs-sdr104: Delay value for SD UHS SDR50 timing.
-- sprd,phy-delay-mmc-highspeed: Delay value for MMC high-speed timing.

-
-Required properties:
- - compatible : "cdns,hp-nfc"
- - reg : Contains two entries, each of which is a tuple consisting of a
- physical address and length. The first entry is the address and
- length of the controller register set. The second entry is the
- address and length of the Slave DMA data port.
- - reg-names: should contain "reg" and "sdma"
- - #address-cells: should be 1. The cell encodes the chip select connection.
- - #size-cells : should be 0.
- - interrupts : The interrupt number.
- - clocks: phandle of the controller core clock (nf_clk).
-
-Optional properties:
- - dmas: shall reference DMA channel associated to the NAND controller
- - cdns,board-delay-ps : Estimated Board delay. The value includes the total
- round trip delay for the signals and is used for deciding on values
- associated with data read capture. The example formula for SDR mode is
- the following:
- board delay = RE#PAD delay + PCB trace to device + PCB trace from device
- + DQ PAD delay
-
-Child nodes represent the available NAND chips.
-
-Required properties of NAND chips:
- - reg: shall contain the native Chip Select ids from 0 to max supported by
- the cadence nand flash controller
-
-See Documentation/devicetree/bindings/mtd/nand-controller.yaml for more details on
-generic bindings.

-Marvell NAND Flash Controller (NFC)
-
-Required properties:
-- compatible: can be one of the following:
- * "marvell,armada-8k-nand-controller"
- * "marvell,armada370-nand-controller"
- * "marvell,pxa3xx-nand-controller"
- * "marvell,armada-8k-nand" (deprecated)
- * "marvell,armada370-nand" (deprecated)
- * "marvell,pxa3xx-nand" (deprecated)
- Compatibles marked deprecated support only the old bindings described
- at the bottom.
-- reg: NAND flash controller memory area.
-- #address-cells: shall be set to 1. Encode the NAND CS.
-- #size-cells: shall be set to 0.
-- interrupts: shall define the NAND controller interrupt.
-- clocks: shall reference the NAND controller clocks, the second one is
- is only needed for the Armada 7K/8K SoCs
-- clock-names: mandatory if there is a second clock, in this case there
- should be one clock named "core" and another one named "reg"
-- marvell,system-controller: Set to retrieve the syscon node that handles
- NAND controller related registers (only required with the
- "marvell,armada-8k-nand[-controller]" compatibles).
-
-Optional properties:
-- label: see partition.txt. New platforms shall omit this property.
-- dmas: shall reference DMA channel associated to the NAND controller.
- This property is only used with "marvell,pxa3xx-nand[-controller]"
- compatible strings.
-- dma-names: shall be "rxtx".
- This property is only used with "marvell,pxa3xx-nand[-controller]"
- compatible strings.
-
-Optional children nodes:
-Children nodes represent the available NAND chips.
-
-Required properties:
-- reg: shall contain the native Chip Select ids (0-3).
-- nand-rb: see nand-controller.yaml (0-1).
-
-Optional properties:
-- marvell,nand-keep-config: orders the driver not to take the timings
- from the core and leaving them completely untouched. Bootloader
- timings will then be used.
-- label: MTD name.
-- nand-on-flash-bbt: see nand-controller.yaml.
-- nand-ecc-mode: see nand-controller.yaml. Will use hardware ECC if not specified.
-- nand-ecc-algo: see nand-controller.yaml. This property is essentially useful when
- not using hardware ECC. Howerver, it may be added when using hardware
- ECC for clarification but will be ignored by the driver because ECC
- mode is chosen depending on the page size and the strength required by
- the NAND chip. This value may be overwritten with nand-ecc-strength
- property.
-- nand-ecc-strength: see nand-controller.yaml.
-- nand-ecc-step-size: see nand-controller.yaml. Marvell's NAND flash controller does
- use fixed strength (1-bit for Hamming, 16-bit for BCH), so the actual
- step size will shrink or grow in order to fit the required strength.
- Step sizes are not completely random for all and follow certain
- patterns described in AN-379, "Marvell SoC NFC ECC".
-
-See Documentation/devicetree/bindings/mtd/nand-controller.yaml for more details on
-generic bindings.
-
-
-Example:
-nand_controller: nand-controller@d0000 {
- compatible = "marvell,armada370-nand-controller";
- reg = <0xd0000 0x54>;
- #address-cells = <1>;
- #size-cells = <0>;
- interrupts = <GIC_SPI 84 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&coredivclk 0>;
-
- nand@0 {
- reg = <0>;
- label = "main-storage";
- nand-rb = <0>;
- nand-ecc-mode = "hw";
- marvell,nand-keep-config;
- nand-on-flash-bbt;
- nand-ecc-strength = <4>;
- nand-ecc-step-size = <512>;
-
- partitions {
- compatible = "fixed-partitions";
- #address-cells = <1>;
- #size-cells = <1>;
-
- partition@0 {
- label = "Rootfs";
- reg = <0x00000000 0x40000000>;
- };
- };
- };
-};
-
-
-Note on legacy bindings: One can find, in not-updated device trees,
-bindings slightly different than described above with other properties
-described below as well as the partitions node at the root of a so
-called "nand" node (without clear controller/chip separation).
-
-Legacy properties:
-- marvell,nand-enable-arbiter: To enable the arbiter, all boards blindly
- used it, this bit was set by the bootloader for many boards and even if
- it is marked reserved in several datasheets, it might be needed to set
- it (otherwise it is harmless) so whether or not this property is set,
- the bit is selected by the driver.
-- num-cs: Number of chip-select lines to use, all boards blindly set 1
- to this and for a reason, other values would have failed. The value of
- this property is ignored.
-
-Example:
-
- nand0: nand@43100000 {
- compatible = "marvell,pxa3xx-nand";
- reg = <0x43100000 90>;
- interrupts = <45>;
- dmas = <&pdma 97 0>;
- dma-names = "rxtx";
- #address-cells = <1>;
- marvell,nand-keep-config;
- marvell,nand-enable-arbiter;
- num-cs = <1>;
- /* Partitions (optional) */

+description: The SEAttle iMAge (SEAMA) partition is a type of partition
+ used for NAND flash devices. This type of flash image is found in some
+ D-Link routers such as DIR-645, DIR-842, DIR-859, DIR-860L, DIR-885L,
+ DIR890L and DCH-M225, as well as in WD and NEC routers on the ath79
+ (MIPS), Broadcom BCM53xx, and RAMIPS platforms. This partition type
+ does not have children defined in the device tree, they need to be
+ detected by software.

-Freescale's NAND flash controller (NFC)
-
-This variant of the Freescale NAND flash controller (NFC) can be found on
-Vybrid (vf610), MPC5125, MCF54418 and Kinetis K70.
-
-Required properties:
-- compatible: Should be set to "fsl,vf610-nfc".
-- reg: address range of the NFC.
-- interrupts: interrupt of the NFC.
-- #address-cells: shall be set to 1. Encode the nand CS.
-- #size-cells : shall be set to 0.
-- assigned-clocks: main clock from the SoC, for Vybrid <&clks VF610_CLK_NFC>;
-- assigned-clock-rates: The NAND bus timing is derived from this clock
- rate and should not exceed maximum timing for any NAND memory chip
- in a board stuffing. Typical NAND memory timings derived from this
- clock are found in the SoC hardware reference manual. Furthermore,
- there might be restrictions on maximum rates when using hardware ECC.
-
-- #address-cells, #size-cells : Must be present if the device has sub-nodes
- representing partitions.
-
-Required children nodes:
-Children nodes represent the available nand chips. Currently the driver can
-only handle one NAND chip.
-
-Required properties:
-- compatible: Should be set to "fsl,vf610-nfc-cs".
-- nand-bus-width: see nand-controller.yaml
-- nand-ecc-mode: see nand-controller.yaml
-
-Required properties for hardware ECC:
-- nand-ecc-strength: supported strengths are 24 and 32 bit (see nand-controller.yaml)
-- nand-ecc-step-size: step size equals page size, currently only 2k pages are
- supported
-- nand-on-flash-bbt: see nand-controller.yaml
-
-Example:
-
- nfc: nand@400e0000 {
- compatible = "fsl,vf610-nfc";
- #address-cells = <1>;
- #size-cells = <0>;
- reg = <0x400e0000 0x4000>;
- interrupts = <GIC_SPI 83 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&clks VF610_CLK_NFC>;
- clock-names = "nfc";
- assigned-clocks = <&clks VF610_CLK_NFC>;
- assigned-clock-rates = <33000000>;

- reg = <0>;
- nand-bus-width = <8>;
- nand-ecc-mode = "hw";

+ Aeonsemi AS21xxx Ethernet PHYs requires a firmware to be loaded to actually
+ work. The same firmware is compatible with various PHYs of the same family.
+
+ A PHY with not firmware loaded will be exposed on the MDIO bus with ID
+ 0x7500 0x7500 or 0x7500 0x9410 on C45 registers.
+
+ This can be done and is implemented by OEM in 2 different way:
+ - Attached SPI flash directly to the PHY with the firmware. The PHY
+ will self load the firmware in the presence of this configuration.
+ - Manually provided firmware loaded from a file in the filesystem.
+
+ Each PHY can support up to 5 LEDs.

- - MAC registers
- - PCS registers
- - SerDes Rx/Tx registers
- - SerDes integration registers (1/2)
- - SerDes integration registers (2/2)
-- interrupts: Should contain the amd-xgbe interrupt(s). The first interrupt
- listed is required and is the general device interrupt. If the optional
- amd,per-channel-interrupt property is specified, then one additional
- interrupt for each DMA channel supported by the device should be specified.
- The last interrupt listed should be the PCS auto-negotiation interrupt.
-- clocks:
- - DMA clock for the amd-xgbe device (used for calculating the
- correct Rx interrupt watchdog timer value on a DMA channel
- for coalescing)
- - PTP clock for the amd-xgbe device
-- clock-names: Should be the names of the clocks
- - "dma_clk" for the DMA clock
- - "ptp_clk" for the PTP clock
-- phy-mode: See ethernet.txt file in the same directory
-
-Optional properties:
-- dma-coherent: Present if dma operations are coherent
-- amd,per-channel-interrupt: Indicates that Rx and Tx complete will generate
- a unique interrupt for each DMA channel - this requires an additional
- interrupt be configured for each DMA channel
-- amd,speed-set: Speed capabilities of the device
- 0 - 1GbE and 10GbE (default)
- 1 - 2.5GbE and 10GbE
-
-The MAC address will be determined using the optional properties defined in
-ethernet.txt.
-
-The following optional properties are represented by an array with each
-value corresponding to a particular speed. The first array value represents
-the setting for the 1GbE speed, the second value for the 2.5GbE speed and
-the third value for the 10GbE speed. All three values are required if the
-property is used.
-- amd,serdes-blwc: Baseline wandering correction enablement

+MediaTek UART based Bluetooth Devices
+==================================
+
+This device is a serial attached device to UART device and thus it must be a
+child node of the serial node with UART.
+
+Please refer to the following documents for generic properties:
+
+ Documentation/devicetree/bindings/serial/serial.yaml
+
+Required properties:
+
+- compatible: Must be
+ "mediatek,mt7663u-bluetooth": for MT7663U device
+ "mediatek,mt7668u-bluetooth": for MT7668U device
+- vcc-supply: Main voltage regulator
+
+If the pin controller on the platform can support both pinmux and GPIO
+control such as the most of MediaTek platform. Please use below properties.
+
+- pinctrl-names: Should be "default", "runtime"
+- pinctrl-0: Should contain UART RXD low when the device is powered up to
+ enter proper bootstrap mode.
+- pinctrl-1: Should contain UART mode pin ctrl
+
+Else, the pin controller on the platform only can support pinmux control and
+the GPIO control still has to rely on the dedicated GPIO controller such as
+a legacy MediaTek SoC, MT7621. Please use the below properties.
+
+- boot-gpios: GPIO same to the pin as UART RXD and used to keep LOW when
+ the device is powered up to enter proper bootstrap mode when
+- pinctrl-names: Should be "default"
+- pinctrl-0: Should contain UART mode pin ctrl
+
+Optional properties:
+
+- reset-gpios: GPIO used to reset the device whose initial state keeps low,
+ if the GPIO is missing, then board-level design should be
+ guaranteed.
+- clocks: Should be the clock specifiers corresponding to the entry in
+ clock-names property. If the clock is missing, then board-level
+ design should be guaranteed.
+- clock-names: Should contain "osc" entry for the external oscillator.
+- current-speed: Current baud rate of the device whose defaults to 921600
+
+Example:
+
+ uart1_pins_boot: uart1-default {
+ pins-dat {
+ pinmux = <MT7623_PIN_81_URXD1_FUNC_GPIO81>;
+ output-low;
+ };

+ pinmux = <MT7623_PIN_81_URXD1_FUNC_URXD1>,
+ <MT7623_PIN_82_UTXD1_FUNC_UTXD1>;
+ };
+ };

+ "mediatek,mt6577-uart";

+ Message RAM configuration data.
+ Multiple M_CAN instances can share the same Message RAM
+ and each element(e.g Rx FIFO or Tx Buffer and etc) number
+ in Message RAM is also configurable, so this property is
+ telling driver how the shared or private Message RAM are
+ used by this M_CAN controller.
+
+ The format should be as follows:
+ <offset sidf_elems xidf_elems rxf0_elems rxf1_elems rxb_elems txe_elems txb_elems>
+ The 'offset' is an address offset of the Message RAM where
+ the following elements start from. This is usually set to
+ 0x0 if you're using a private Message RAM. The remain cells
+ are used to specify how many elements are used for each FIFO/Buffer.
+
+ M_CAN includes the following elements according to user manual:
+ 11-bit Filter 0-128 elements / 0-128 words
+ 29-bit Filter 0-64 elements / 0-128 words
+ Rx FIFO 0 0-64 elements / 0-1152 words
+ Rx FIFO 1 0-64 elements / 0-1152 words
+ Rx Buffers 0-64 elements / 0-1152 words
+ Tx Event FIFO 0-32 elements / 0-64 words
+ Tx Buffers 0-32 elements / 0-576 words

-Atheros AR9331 built-in switch
-=============================
-
-It is a switch built-in to Atheros AR9331 WiSoC and addressable over internal
-MDIO bus. All PHYs are built-in as well.
-
-Required properties:
-
- - compatible: should be: "qca,ar9331-switch"
- - reg: Address on the MII bus for the switch.
- - resets : Must contain an entry for each entry in reset-names.
- - reset-names : Must include the following entries: "switch"
- - interrupt-parent: Phandle to the parent interrupt controller
- - interrupts: IRQ line for the switch
- - interrupt-controller: Indicates the switch is itself an interrupt
- controller. This is used for the PHY interrupts.
- - #interrupt-cells: must be 1
- - mdio: Container of PHY and devices on the switches MDIO bus.

-Marvell DSA Switch Device Tree Bindings
----------------------------------------
-
-WARNING: This binding is currently unstable. Do not program it into a
-FLASH never to be changed again. Once this binding is stable, this
-warning will be removed.
-
-If you need a stable binding, use the old dsa.txt binding.
-
-Marvell Switches are MDIO devices. The following properties should be
-placed as a child node of an mdio device.
-
-The properties described here are those specific to Marvell devices.
-Additional required and optional properties can be found in dsa.txt.
-
-The compatibility string is used only to find an identification register,
-which is at a different MDIO base address in different switch families.

+description:
+ The Micrel KS8995 DSA Switches are 100 Mbit switches that were produced in
+ the early-to-mid 2000s. The chip features a CPU port and four outgoing ports,
+ each with an internal PHY. The chip itself is managed over SPI, but all the
+ PHYs need to be accessed from an external MDIO channel.
+
+ Further, a fifth PHY is available and can be used separately from the switch
+ fabric, connected to an external MII interface name MII-P5. This is
+ unrelated from the CPU-facing port 5 which is used for DSA MII traffic.

-Vitesse VSC73xx Switches
-========================
-
-This defines device tree bindings for the Vitesse VSC73xx switch chips.
-The Vitesse company has been acquired by Microsemi and Microsemi has
-been acquired Microchip but retains this vendor branding.
-
-The currently supported switch chips are:
-Vitesse VSC7385 SparX-G5 5+1-port Integrated Gigabit Ethernet Switch
-Vitesse VSC7388 SparX-G8 8-port Integrated Gigabit Ethernet Switch
-Vitesse VSC7395 SparX-G5e 5+1-port Integrated Gigabit Ethernet Switch
-Vitesse VSC7398 SparX-G8e 8-port Integrated Gigabit Ethernet Switch
-
-This switch could have two different management interface.
-
-If SPI interface is used, the device tree node is an SPI device so it must
-reside inside a SPI bus device tree node, see spi/spi-bus.txt
-
-When the chip is connected to a parallel memory bus and work in memory-mapped
-I/O mode, a platform device is used to represent the vsc73xx. In this case it
-must reside inside a platform bus device tree node.
-
-Required properties:
-
-- compatible: must be exactly one of:
- "vitesse,vsc7385"
- "vitesse,vsc7388"
- "vitesse,vsc7395"
- "vitesse,vsc7398"
-- gpio-controller: indicates that this switch is also a GPIO controller,
- see gpio/gpio.txt
-- #gpio-cells: this must be set to <2> and indicates that we are a twocell
- GPIO controller, see gpio/gpio.txt
-
-Optional properties:
-
-- reset-gpios: a handle to a GPIO line that can issue reset of the chip.
- It should be tagged as active low.
-
-Required subnodes:
-
-See net/dsa/dsa.txt for a list of additional required and optional properties
-and subnodes of DSA switches.
-
-Examples:
-
-SPI:

+#
+# 'phy-modes' & 'phy-connection-type' properties 'rgmii', 'rgmii-id',
+# 'rgmii-rxid', and 'rgmii-txid' are frequently used wrongly by
+# developers. This informative section clarifies their usage.
+#
+# The RGMII specification requires a 2ns delay between the data and
+# clock signals on the RGMII bus. How this delay is implemented is not
+# specified.
+#
+# One option is to make the clock traces on the PCB longer than the
+# data traces. A sufficient difference in length can provide the 2ns
+# delay. If both the RX and TX delays are implemented in this manner,
+# 'rgmii' should be used, so indicating the PCB adds the delays.
+#
+# If the PCB does not add these delays via extra long traces,
+# 'rgmii-id' should be used. Here, 'id' refers to 'internal delay',
+# where either the MAC or PHY adds the delay.
+#
+# If only one of the two delays are implemented via extra long clock
+# lines, either 'rgmii-rxid' or 'rgmii-txid' should be used,
+# indicating the MAC or PHY should implement one of the delays
+# internally, while the PCB implements the other delay.
+#
+# Device Tree describes hardware, and in this case, it describes the
+# PCB between the MAC and the PHY, if the PCB implements delays or
+# not.
+#
+# In practice, very few PCBs make use of extra long clock lines. Hence
+# any RGMII phy mode other than 'rgmii-id' is probably wrong, and is
+# unlikely to be accepted during review without details provided in
+# the commit description and comments in the .dts file.
+#
+# When the PCB does not implement the delays, the MAC or PHY must. As
+# such, this is software configuration, and so not described in Device
+# Tree.
+#
+# The following describes how Linux implements the configuration of
+# the MAC and PHY to add these delays when the PCB does not. As stated
+# above, developers often get this wrong, and the aim of this section
+# is reduce the frequency of these errors by Linux developers. Other
+# users of the Device Tree may implement it differently, and still be
+# consistent with both the normative and informative description
+# above.
+#
+# By default in Linux, when using phylib/phylink, the MAC is expected
+# to read the 'phy-mode' from Device Tree, not implement any delays,
+# and pass the value to the PHY. The PHY will then implement delays as
+# specified by the 'phy-mode'. The PHY should always be reconfigured
+# to implement the needed delays, replacing any setting performed by
+# strapping or the bootloader, etc.
+#
+# Experience to date is that all PHYs which implement RGMII also
+# implement the ability to add or not add the needed delays. Hence
+# this default is expected to work in all cases. Ignoring this default
+# is likely to be questioned by Reviews, and require a strong argument
+# to be accepted.
+#
+# There are a small number of cases where the MAC has hard coded
+# delays which cannot be disabled. The 'phy-mode' only describes the
+# PCB. The inability to disable the delays in the MAC does not change
+# the meaning of 'phy-mode'. It does however mean that a 'phy-mode' of
+# 'rgmii' is now invalid, it cannot be supported, since both the PCB
+# and the MAC and PHY adding delays cannot result in a functional
+# link. Thus the MAC should report a fatal error for any modes which
+# cannot be supported. When the MAC implements the delay, it must
+# ensure that the PHY does not also implement the same delay. So it
+# must modify the phy-mode it passes to the PHY, removing the delay it
+# has added. Failure to remove the delay will result in a
+# non-functioning link.
+#
+# Sometimes there is a need to fine tune the delays. Often the MAC or
+# PHY can perform this fine tuning. In the MAC node, the Device Tree
+# properties 'rx-internal-delay-ps' and 'tx-internal-delay-ps' should
+# be used to indicate fine tuning performed by the MAC. The values
+# expected here are small. A value of 2000ps, i.e 2ns, and a phy-mode
+# of 'rgmii' will not be accepted by Reviewers.
+#
+# If the PHY is to perform fine tuning, the properties
+# 'rx-internal-delay-ps' and 'tx-internal-delay-ps' in the PHY node
+# should be used. When the PHY is implementing delays, e.g. 'rgmii-id'
+# these properties should have a value near to 2000ps. If the PCB is
+# implementing delays, e.g. 'rgmii', a small value can be used to fine
+# tune the delay added by the PCB.

+
+description:
+ This binding describes the MDIO is a bus to which the PHY devices are
+ connected. For each device that exists on this bus, a child node should be
+ created.
+
+ Some TSECs are associated with an internal Ten-Bit Interface (TBI) PHY. This
+ PHY is accessed through the local MDIO bus. These buses are defined similarly
+ to the mdio buses, except they are compatible with "fsl,gianfar-tbi". The TBI
+ PHYs underneath them are similar to normal PHYs, but the reg property is
+ considered instructive, rather than descriptive. The reg property should be
+ chosen so it doesn't interfere with other PHYs on the bus.

-* ENETC ethernet device tree bindings
-
-Depending on board design and ENETC port type (internal or
-external) there are two supported link modes specified by
-below device tree bindings.
-
-Required properties:
-
-- reg : Specifies PCIe Device Number and Function
- Number of the ENETC endpoint device, according
- to parent node bindings.
-- compatible : Should be "fsl,enetc".
-
-1. The ENETC external port is connected to a MDIO configurable phy
-
-1.1. Using the local ENETC Port MDIO interface
-
-In this case, the ENETC node should include a "mdio" sub-node
-that in turn should contain the "ethernet-phy" node describing the
-external phy. Below properties are required, their bindings
-already defined in Documentation/devicetree/bindings/net/ethernet.txt or
-Documentation/devicetree/bindings/net/phy.txt.
-
-Required:
-
-- phy-handle : Phandle to a PHY on the MDIO bus.
- Defined in ethernet.txt.
-
-- phy-connection-type : Defined in ethernet.txt.
-
-- mdio : "mdio" node, defined in mdio.txt.
-
-- ethernet-phy : "ethernet-phy" node, defined in phy.txt.
-
-Example:
-
- ethernet@0,0 {
- compatible = "fsl,enetc";
- reg = <0x000000 0 0 0 0>;
- phy-handle = <&sgmii_phy0>;
- phy-connection-type = "sgmii";
-
- mdio {
- #address-cells = <1>;
- #size-cells = <0>;
- sgmii_phy0: ethernet-phy@2 {
- reg = <0x2>;
- };
- };
- };
-
-1.2. Using the central MDIO PCIe endpoint device
-
-In this case, the mdio node should be defined as another PCIe
-endpoint node, at the same level with the ENETC port nodes.
-
-Required properties:
-
-- reg : Specifies PCIe Device Number and Function
- Number of the ENETC endpoint device, according
- to parent node bindings.
-- compatible : Should be "fsl,enetc-mdio".
-
-The remaining required mdio bus properties are standard, their bindings
-already defined in Documentation/devicetree/bindings/net/mdio.txt.
-
-Example:
-
- ethernet@0,0 {
- compatible = "fsl,enetc";
- reg = <0x000000 0 0 0 0>;
- phy-handle = <&sgmii_phy0>;
- phy-connection-type = "sgmii";
- };
-
- mdio@0,3 {
- compatible = "fsl,enetc-mdio";
- reg = <0x000300 0 0 0 0>;
- #address-cells = <1>;
- #size-cells = <0>;
- sgmii_phy0: ethernet-phy@2 {
- reg = <0x2>;
- };
- };
-
-2. The ENETC port is an internal port or has a fixed-link external
-connection
-
-In this case, the ENETC port node defines a fixed link connection,
-as specified by Documentation/devicetree/bindings/net/fixed-link.txt.
-
-Required:
-
-- fixed-link : "fixed-link" node, defined in "fixed-link.txt".
-
-Example:
- ethernet@0,2 {
- compatible = "fsl,enetc";
- reg = <0x000200 0 0 0 0>;
- fixed-link {
- speed = <1000>;
- full-duplex;
- };
- };
-
-* Integrated Endpoint Register Block bindings
-
-Optionally, the fsl_enetc driver can probe on the Integrated Endpoint Register
-Block, which preconfigures the FIFO limits for the ENETC ports. This is a node
-with the following properties:
-
-- reg : Specifies the address in the SoC memory space.
-- compatible : Must be "fsl,ls1028a-enetc-ierb".
-
-Example:
- ierb@1f0800000 {
- compatible = "fsl,ls1028a-enetc-ierb";
- reg = <0x01 0xf0800000 0x0 0x10000>;
- };

- internal PCS registers may result in having the
- MDIO_CFG[MDIO_RD_ER] bit set, even when there is no error and
- read data (MDIO_DATA[MDIO_DATA]) is correct.
- Software may get false read error when reading internal
- PCS registers through MDIO. As a workaround, all internal
- MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.
-
-For internal PHY device on internal mdio bus, a PHY node should be created.
-See the definition of the PHY node in booting-without-of.txt for an
-example of how to define a PHY (Internal PHY has no interrupt line).
-- For "fsl,fman-mdio" compatible internal mdio bus, the PHY is TBI PHY.
-- For "fsl,fman-memac-mdio" compatible internal mdio bus, the PHY is PCS PHY.
- The PCS PHY address should correspond to the value of the appropriate
- MDEV_PORT.

* MDIO IO device
-The MDIO is a bus to which the PHY devices are connected. For each
-device that exists on this bus, a child node should be created. See
-the definition of the PHY node in booting-without-of.txt for an example
-of how to define a PHY.
-
-Required properties:
- - reg : Offset and length of the register set for the device, and optionally
- the offset and length of the TBIPA register (TBI PHY address
- register). If TBIPA register is not specified, the driver will
- attempt to infer it from the register set specified (your mileage may
- vary).
- - compatible : Should define the compatible device type for the
- mdio. Currently supported strings/devices are:
- - "fsl,gianfar-tbi"
- - "fsl,gianfar-mdio"
- - "fsl,etsec2-tbi"
- - "fsl,etsec2-mdio"
- - "fsl,ucc-mdio"
- - "fsl,fman-mdio"
- When device_type is "mdio", the following strings are also considered:
- - "gianfar"
- - "ucc_geth_phy"
-
-Example:
-
- mdio@24520 {
- reg = <24520 20>;
- compatible = "fsl,gianfar-mdio";
-
- ethernet-phy@0 {
- ......
- };
- };
+Refer to Documentation/devicetree/bindings/net/fsl,gianfar-mdio.yaml
* TBI Internal MDIO bus
-As of this writing, every tsec is associated with an internal TBI PHY.
-This PHY is accessed through the local MDIO bus. These buses are defined
-similarly to the mdio buses, except they are compatible with "fsl,gianfar-tbi".
-The TBI PHYs underneath them are similar to normal PHYs, but the reg property
-is considered instructive, rather than descriptive. The reg property should
-be chosen so it doesn't interfere with other PHYs on the bus.
+Refer to Documentation/devicetree/bindings/net/fsl,gianfar-mdio.yaml
* Gianfar-compatible ethernet nodes
-Properties:
-
- - device_type : Should be "network"
- - model : Model of the device. Can be "TSEC", "eTSEC", or "FEC"
- - compatible : Should be "gianfar"
- - reg : Offset and length of the register set for the device
- - interrupts : For FEC devices, the first interrupt is the device's
- interrupt. For TSEC and eTSEC devices, the first interrupt is
- transmit, the second is receive, and the third is error.
- - phy-handle : See ethernet.txt file in the same directory.
- - fixed-link : See fixed-link.txt in the same directory.
- - phy-connection-type : See ethernet.txt file in the same directory.
- This property is only really needed if the connection is of type
- "rgmii-id", as all other connection types are detected by hardware.
- - fsl,magic-packet : If present, indicates that the hardware supports
- waking up via magic packet.
- - fsl,wake-on-filer : If present, indicates that the hardware supports
- waking up by Filer General Purpose Interrupt (FGPI) asserted on the
- Rx int line. This is an advanced power management capability allowing
- certain packet types (user) defined by filer rules to wake up the system.
- - bd-stash : If present, indicates that the hardware supports stashing
- buffer descriptors in the L2.
- - rx-stash-len : Denotes the number of bytes of a received buffer to stash
- in the L2.
- - rx-stash-idx : Denotes the index of the first byte from the received
- buffer to stash in the L2.
-
-Example:
- ethernet@24000 {
- device_type = "network";
- model = "TSEC";
- compatible = "gianfar";
- reg = <0x24000 0x1000>;
- local-mac-address = [ 00 E0 0C 00 73 00 ];

-Marvell 8897/8997 (sd8897/sd8997) bluetooth devices (SDIO or USB based)
-------
-The 8997 devices supports multiple interfaces. When used on SDIO interfaces,
-the btmrvl driver is used and when used on USB interface, the btusb driver is
-used.
-
-Required properties:
-
- - compatible : should be one of the following:
- * "marvell,sd8897-bt" (for SDIO)
- * "marvell,sd8997-bt" (for SDIO)
- * "usb1286,204e" (for USB)
-
-Optional properties:
-
- - marvell,cal-data: Calibration data downloaded to the device during
- initialization. This is an array of 28 values(u8).
- This is only applicable to SDIO devices.
-
- - marvell,wakeup-pin: It represents wakeup pin number of the bluetooth chip.
- firmware will use the pin to wakeup host system (u16).
- - marvell,wakeup-gap-ms: wakeup gap represents wakeup latency of the host
- platform. The value will be configured to firmware. This
- is needed to work chip's sleep feature as expected (u16).
- - interrupt-names: Used only for USB based devices (See below)
- - interrupts : specifies the interrupt pin number to the cpu. For SDIO, the
- driver will use the first interrupt specified in the interrupt
- array. For USB based devices, the driver will use the interrupt
- named "wakeup" from the interrupt-names and interrupt arrays.
- The driver will request an irq based on this interrupt number.
- During system suspend, the irq will be enabled so that the
- bluetooth chip can wakeup host platform under certain
- conditions. During system resume, the irq will be disabled
- to make sure unnecessary interrupt is not received.
-
-Example:
-
-IRQ pin 119 is used as system wakeup source interrupt.
-wakeup pin 13 and gap 100ms are configured so that firmware can wakeup host
-using this device side pin and wakeup latency.
-
-Example for SDIO device follows (calibration data is also available in
-below example).

- to be chosen between 128 and 16352 and it also has to be aligned to 32.
- Otherwise the driver would adjust a given number or choose default if
- not set.
-- pool<0 : 3>,pkt-size: maximum size of a packet accepted by a given buffer
- pointers' pool (id 0 : 3). It will be taken into consideration only when pool
- type is 'short'. For 'long' ones it would be overridden by port's MTU.
- If not set a driver will choose a default value.

-MediaTek SoC built-in Bluetooth Devices
-==================================
-
-This device is a serial attached device to BTIF device and thus it must be a
-child node of the serial node with BTIF. The dt-bindings details for BTIF
-device can be known via Documentation/devicetree/bindings/serial/8250.yaml.
-
-Required properties:
-
-- compatible: Must be
- "mediatek,mt7622-bluetooth": for MT7622 SoC
-- clocks: Should be the clock specifiers corresponding to the entry in
- clock-names property.
-- clock-names: Should contain "ref" entries.
-- power-domains: Phandle to the power domain that the device is part of

-MediaTek UART based Bluetooth Devices
-==================================
-
-This device is a serial attached device to UART device and thus it must be a
-child node of the serial node with UART.
-
-Please refer to the following documents for generic properties:
-
- Documentation/devicetree/bindings/serial/serial.yaml
-
-Required properties:
-

- "mediatek,mt7663u-bluetooth": for MT7663U device
- "mediatek,mt7668u-bluetooth": for MT7668U device
-- vcc-supply: Main voltage regulator
-
-If the pin controller on the platform can support both pinmux and GPIO
-control such as the most of MediaTek platform. Please use below properties.
-
-- pinctrl-names: Should be "default", "runtime"
-- pinctrl-0: Should contain UART RXD low when the device is powered up to
- enter proper bootstrap mode.
-- pinctrl-1: Should contain UART mode pin ctrl
-
-Else, the pin controller on the platform only can support pinmux control and
-the GPIO control still has to rely on the dedicated GPIO controller such as
-a legacy MediaTek SoC, MT7621. Please use the below properties.
-
-- boot-gpios: GPIO same to the pin as UART RXD and used to keep LOW when
- the device is powered up to enter proper bootstrap mode when
-- pinctrl-names: Should be "default"
-- pinctrl-0: Should contain UART mode pin ctrl
-
-Optional properties:
-
-- reset-gpios: GPIO used to reset the device whose initial state keeps low,
- if the GPIO is missing, then board-level design should be
- guaranteed.
-- clocks: Should be the clock specifiers corresponding to the entry in
- clock-names property. If the clock is missing, then board-level
- design should be guaranteed.
-- clock-names: Should contain "osc" entry for the external oscillator.
-- current-speed: Current baud rate of the device whose defaults to 921600

-Optional properties:
-- vsc8531,vddmac : The vddmac in mV. Allowed values is listed
- in the first row of Table 1 (below).
- This property is only used in combination
- with the 'edge-slowdown' property.
- Default value is 3300.
-- vsc8531,edge-slowdown : % the edge should be slowed down relative to
- the fastest possible edge time.
- Edge rate sets the drive strength of the MAC
- interface output signals. Changing the
- drive strength will affect the edge rate of
- the output signal. The goal of this setting
- is to help reduce electrical emission (EMI)
- by being able to reprogram drive strength
- and in effect slow down the edge rate if
- desired.
- To adjust the edge-slowdown, the 'vddmac'
- must be specified. Table 1 lists the
- supported edge-slowdown values for a given
- 'vddmac'.
- Default value is 0%.
- Ref: Table:1 - Edge rate change (below).
-- vsc8531,led-[N]-mode : LED mode. Specify how the LED[N] should behave.
- N depends on the number of LEDs supported by a
- PHY.
- Allowed values are defined in
- "include/dt-bindings/net/mscc-phy-vsc8531.h".
- Default values are VSC8531_LINK_1000_ACTIVITY (1),
- VSC8531_LINK_100_ACTIVITY (2),
- VSC8531_LINK_ACTIVITY (0) and
- VSC8531_DUPLEX_COLLISION (8).

- hardware clock (PHC).

+description:
+ Synopsys DesignWare Ethernet Physical Coding Sublayer provides an interface
+ between Media Access Control and Physical Medium Attachment Sublayer through
+ the Media Independent Interface (XGMII, USXGMII, XLGMII, GMII, etc)
+ controlled by means of the IEEE std. Clause 45 registers set. The PCS can be
+ optionally synthesized with a vendor-specific interface connected to
+ Synopsys PMA (also called DesignWare Consumer/Enterprise PHY) although in
+ general it can be used to communicate with any compatible PHY.
+
+ The PCS CSRs can be accessible either over the Ethernet MDIO bus or directly
+ by means of the APB3/MCI interfaces. In the later case the XPCS can be mapped
+ right to the system IO memory space.

-* Qualcomm QCA7000
-
-The QCA7000 is a serial-to-powerline bridge with a host interface which could
-be configured either as SPI or UART slave. This configuration is done by
-the QCA7000 firmware.
-
-(a) Ethernet over SPI
-
-In order to use the QCA7000 as SPI device it must be defined as a child of a
-SPI master in the device tree.
-
-Required properties:
-- compatible : Should be "qca,qca7000"
-- reg : Should specify the SPI chip select
-- interrupts : The first cell should specify the index of the source
- interrupt and the second cell should specify the trigger
- type as rising edge
-- spi-cpha : Must be set
-- spi-cpol : Must be set
-
-Optional properties:
-- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at.
- Numbers smaller than 1000000 or greater than 16000000
- are invalid. Missing the property will set the SPI
- frequency to 8000000 Hertz.
-- qca,legacy-mode : Set the SPI data transfer of the QCA7000 to legacy mode.
- In this mode the SPI master must toggle the chip select
- between each data word. In burst mode these gaps aren't
- necessary, which is faster. This setting depends on how
- the QCA7000 is setup via GPIO pin strapping. If the
- property is missing the driver defaults to burst mode.
-
-The MAC address will be determined using the optional properties
-defined in ethernet.txt.
-
-SPI Example:
-
-/* Freescale i.MX28 SPI master*/
-ssp2: spi@80014000 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "fsl,imx28-spi";
- pinctrl-names = "default";
- pinctrl-0 = <&spi2_pins_a>;
-
- qca7000: ethernet@0 {
- compatible = "qca,qca7000";
- reg = <0x0>;
- interrupt-parent = <&gpio3>; /* GPIO Bank 3 */
- interrupts = <25 0x1>; /* Index: 25, rising edge */
- spi-cpha; /* SPI mode: CPHA=1 */
- spi-cpol; /* SPI mode: CPOL=1 */
- spi-max-frequency = <8000000>; /* freq: 8 MHz */
- local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
- };
-};
-
-(b) Ethernet over UART
-
-In order to use the QCA7000 as UART slave it must be defined as a child of a
-UART master in the device tree. It is possible to preconfigure the UART
-settings of the QCA7000 firmware, but it's not possible to change them during
-runtime.
-
-Required properties:
-- compatible : Should be "qca,qca7000"
-
-Optional properties:
-- local-mac-address : see ./ethernet.txt
-- current-speed : current baud rate of QCA7000 which defaults to 115200
- if absent, see also ../serial/serial.yaml
-
-UART Example:
-
-/* Freescale i.MX28 UART */
-auart0: serial@8006a000 {
- compatible = "fsl,imx28-auart", "fsl,imx23-auart";
- reg = <0x8006a000 0x2000>;
- pinctrl-names = "default";
- pinctrl-0 = <&auart0_2pins_a>;
-
- qca7000: ethernet {
- compatible = "qca,qca7000";
- local-mac-address = [ A0 B0 C0 D0 E0 F0 ];
- current-speed = <38400>;
- };

+
+description: |
+ The Ethernet functionality in the PPE (Packet Process Engine) is comprised
+ of three components, the switch core, port wrapper and Ethernet DMA.
+
+ The Switch core in the IPQ9574 PPE has maximum of 6 front panel ports and
+ two FIFO interfaces. One of the two FIFO interfaces is used for Ethernet
+ port to host CPU communication using Ethernet DMA. The other is used
+ communicating to the EIP engine which is used for IPsec offload. On the
+ IPQ9574, the PPE includes 6 GMAC/XGMACs that can be connected with external
+ Ethernet PHY. Switch core also includes BM (Buffer Management), QM (Queue
+ Management) and SCH (Scheduler) modules for supporting the packet processing.
+
+ The port wrapper provides connections from the 6 GMAC/XGMACS to UNIPHY (PCS)
+ supporting various modes such as SGMII/QSGMII/PSGMII/USXGMII/10G-BASER. There
+ are 3 UNIPHY (PCS) instances supported on the IPQ9574.
+
+ Ethernet DMA is used to transmit and receive packets between the six Ethernet
+ ports and ARM host CPU.
+
+ The follow diagram shows the PPE hardware block along with its connectivity
+ to the external hardware blocks such clock hardware blocks (CMNPLL, GCC,
+ NSS clock controller) and Ethernet PCS/PHY blocks. For depicting the PHY
+ connectivity, one 4x1 Gbps PHY (QCA8075) and two 10 GBps PHYs are used as an
+ example.

+description: |
+ Qualcomm QCA8072/5 Ethernet PHY is PHY package of 2 or 5
+ IEEE 802.3 clause 22 compliant 10BASE-Te, 100BASE-TX and
+ 1000BASE-T PHY-s.
+
+ They feature 2 SerDes, one for PSGMII or QSGMII connection with
+ MAC, while second one is SGMII for connection to MAC or fiber.
+
+ Both models have a combo port that supports 1000BASE-X and
+ 100BASE-FX fiber.
+
+ Each PHY inside of QCA807x series has 4 digitally controlled
+ output only pins that natively drive LED-s for up to 2 attached
+ LEDs. Some vendor also use these 4 output for GPIO usage without
+ attaching LEDs.
+
+ Note that output pins can be set to drive LEDs OR GPIO, mixed
+ definition are not accepted.

-Altera SOCFPGA SoC DWMAC controller
-
-This is a variant of the dwmac/stmmac driver an inherits all descriptions
-present in Documentation/devicetree/bindings/net/stmmac.txt.
-
-The device node has additional properties:
-
-Required properties:
- - compatible : For Cyclone5/Arria5 SoCs it should contain
- "altr,socfpga-stmmac". For Arria10/Agilex/Stratix10 SoCs
- "altr,socfpga-stmmac-a10-s10".
- Along with "snps,dwmac" and any applicable more detailed
- designware version numbers documented in stmmac.txt
- - altr,sysmgr-syscon : Should be the phandle to the system manager node that
- encompasses the glue register, the register offset, and the register shift.
- On Cyclone5/Arria5, the register shift represents the PHY mode bits, while
- on the Arria10/Stratix10/Agilex platforms, the register shift represents
- bit for each emac to enable/disable signals from the FPGA fabric to the
- EMAC modules.
- - altr,f2h_ptp_ref_clk use f2h_ptp_ref_clk instead of default eosc1 clock
- for ptp ref clk. This affects all emacs as the clock is common.
-
-Optional properties:
-altr,emac-splitter: Should be the phandle to the emac splitter soft IP node if
- DWMAC controller is connected emac splitter.
-phy-mode: The phy mode the ethernet operates in
-altr,sgmii-to-sgmii-converter: phandle to the TSE SGMII converter
-
-This device node has additional phandle dependency, the sgmii converter:
-
-Required properties:
- - compatible : Should be altr,gmii-to-sgmii-2.0
- - reg-names : Should be "eth_tse_control_port"
-
-Example:
-
-gmii_to_sgmii_converter: phy@100000240 {
- compatible = "altr,gmii-to-sgmii-2.0";
- reg = <0x00000001 0x00000240 0x00000008>,
- <0x00000001 0x00000200 0x00000040>;
- reg-names = "eth_tse_control_port";
- clocks = <&sgmii_1_clk_0 &emac1 1 &sgmii_clk_125 &sgmii_clk_125>;
- clock-names = "tse_pcs_ref_clk_clock_connection", "tse_rx_cdr_refclk";
-};
-

+ The TH1520 GMAC is described in the TH1520 Peripheral Interface User Manual
+ https://git.beagleboard.org/beaglev-ahead/beaglev-ahead/-/tree/main/docs
+
+ Features include
+ - Compliant with IEEE802.3 Specification
+ - IEEE 1588-2008 standard for precision networked clock synchronization
+ - Supports 10/100/1000Mbps data transfer rate
+ - Supports RGMII/MII interface
+ - Preamble and start of frame data (SFD) insertion in Transmit path
+ - Preamble and SFD deletion in the Receive path
+ - Automatic CRC and pad generation options for receive frames
+ - MDIO master interface for PHY device configuration and management
+
+ The GMAC Registers consists of two parts
+ - APB registers are used to configure clock frequency/clock enable/clock
+ direction/PHY interface type.
+ - AHB registers are use to configure GMAC core (DesignWare Core part).
+ GMAC core register consists of DMA registers and GMAC registers.

-------
-
-This node provides properties for controlling the Marvell SDIO/PCIE wireless device.
-The node is expected to be specified as a child node to the SDIO/PCIE controller that
-connects the device to the system.
-
-Required properties:
-
- - compatible : should be one of the following:
- * "marvell,sd8787"
- * "marvell,sd8897"
- * "marvell,sd8978"
- * "marvell,sd8997"
- * "nxp,iw416"
- * "pci11ab,2b42"
- * "pci1b4b,2b42"
-
-Optional properties:
-
- - marvell,caldata* : A series of properties with marvell,caldata prefix,
- represent calibration data downloaded to the device during
- initialization. This is an array of unsigned 8-bit values.
- the properties should follow below property name and
- corresponding array length:
- "marvell,caldata-txpwrlimit-2g" (length = 566).
- "marvell,caldata-txpwrlimit-5g-sub0" (length = 502).
- "marvell,caldata-txpwrlimit-5g-sub1" (length = 688).
- "marvell,caldata-txpwrlimit-5g-sub2" (length = 750).
- "marvell,caldata-txpwrlimit-5g-sub3" (length = 502).
- - marvell,wakeup-pin : a wakeup pin number of wifi chip which will be configured
- to firmware. Firmware will wakeup the host using this pin
- during suspend/resume.
- - interrupts : interrupt pin number to the cpu. driver will request an irq based on
- this interrupt number. during system suspend, the irq will be enabled
- so that the wifi chip can wakeup host platform under certain condition.
- during system resume, the irq will be disabled to make sure
- unnecessary interrupt is not received.
- - vmmc-supply: a phandle of a regulator, supplying VCC to the card
- - mmc-pwrseq: phandle to the MMC power sequence node. See "mmc-pwrseq-*"
- for documentation of MMC power sequence bindings.
-
-Example:
-
-Tx power limit calibration data is configured in below example.
-The calibration data is an array of unsigned values, the length
-can vary between hw versions.
-IRQ pin 38 is used as system wakeup source interrupt. wakeup pin 3 is configured
-so that firmware can wakeup host using this device side pin.

+description: |
+ Qualcomm Technologies IEEE 802.11be PCIe devices with WSI interface.
+
+ The ath12k devices (QCN9274) feature WSI support. WSI stands for
+ WLAN Serial Interface. It is used for the exchange of specific
+ control information across radios based on the doorbell mechanism.
+ This WSI connection is essential to exchange control information
+ among these devices.
+
+ The WSI interface includes TX and RX ports, which are used to connect
+ multiple WSI-supported devices together, forming a WSI group.
+
+ Diagram to represent one WSI connection (one WSI group) among
+ three devices.

-XILINX AXI ETHERNET Device Tree Bindings
---------------------------------------------------------
-
-Also called AXI 1G/2.5G Ethernet Subsystem, the xilinx axi ethernet IP core
-provides connectivity to an external ethernet PHY supporting different
-interfaces: MII, GMII, RGMII, SGMII, 1000BaseX. It also includes two
-segments of memory for buffering TX and RX, as well as the capability of
-offloading TX/RX checksum calculation off the processor.
-
-Management configuration is done through the AXI interface, while payload is
-sent and received through means of an AXI DMA controller. This driver
-includes the DMA driver code, so this driver is incompatible with AXI DMA
-driver.
-
-For more details about mdio please refer phy.txt file in the same directory.
-
-Required properties:
-- compatible : Must be one of "xlnx,axi-ethernet-1.00.a",
- "xlnx,axi-ethernet-1.01.a", "xlnx,axi-ethernet-2.01.a"
-- reg : Address and length of the IO space, as well as the address
- and length of the AXI DMA controller IO space, unless
- axistream-connected is specified, in which case the reg
- attribute of the node referenced by it is used.
-- interrupts : Should be a list of 2 or 3 interrupts: TX DMA, RX DMA,
- and optionally Ethernet core. If axistream-connected is
- specified, the TX/RX DMA interrupts should be on that node
- instead, and only the Ethernet core interrupt is optionally
- specified here.
-- phy-handle : Should point to the external phy device if exists. Pointing
- this to the PCS/PMA PHY is deprecated and should be avoided.
- See ethernet.txt file in the same directory.
-- xlnx,rxmem : Set to allocated memory buffer for Rx/Tx in the hardware
-
-Optional properties:
-- phy-mode : See ethernet.txt
-- xlnx,phy-type : Deprecated, do not use, but still accepted in preference
- to phy-mode.
-- xlnx,txcsum : 0 or empty for disabling TX checksum offload,
- 1 to enable partial TX checksum offload,
- 2 to enable full TX checksum offload
-- xlnx,rxcsum : Same values as xlnx,txcsum but for RX checksum offload
-- xlnx,switch-x-sgmii : Boolean to indicate the Ethernet core is configured to
- support both 1000BaseX and SGMII modes. If set, the phy-mode
- should be set to match the mode selected on core reset (i.e.
- by the basex_or_sgmii core input line).
-- clock-names: Tuple listing input clock names. Possible clocks:
- s_axi_lite_clk: Clock for AXI register slave interface
- axis_clk: AXI4-Stream clock for TXD RXD TXC and RXS interfaces
- ref_clk: Ethernet reference clock, used by signal delay
- primitives and transceivers
- mgt_clk: MGT reference clock (used by optional internal
- PCS/PMA PHY)
-
- Note that if s_axi_lite_clk is not specified by name, the
- first clock of any name is used for this. If that is also not
- specified, the clock rate is auto-detected from the CPU clock
- (but only on platforms where this is possible). New device
- trees should specify all applicable clocks by name - the
- fallbacks to an unnamed clock or to CPU clock are only for
- backward compatibility.
-- clocks: Phandles to input clocks matching clock-names. Refer to common
- clock bindings.
-- axistream-connected: Reference to another node which contains the resources
- for the AXI DMA controller used by this device.
- If this is specified, the DMA-related resources from that
- device (DMA registers and DMA TX/RX interrupts) rather
- than this one will be used.
- - mdio : Child node for MDIO bus. Must be defined if PHY access is
- required through the core's MDIO interface (i.e. always,
- unless the PHY is accessed through a different bus).
- Non-standard MDIO bus frequency is supported via
- "clock-frequency", see mdio.yaml.
-
- - pcs-handle: Phandle to the internal PCS/PMA PHY in SGMII or 1000Base-X
- modes, where "pcs-handle" should be used to point
- to the PCS/PMA PHY, and "phy-handle" should point to an
- external PHY if exists.
-
-Example:
- axi_ethernet_eth: ethernet@40c00000 {
- compatible = "xlnx,axi-ethernet-1.00.a";
- device_type = "network";
- interrupt-parent = <&microblaze_0_axi_intc>;
- interrupts = <2 0 1>;
- clock-names = "s_axi_lite_clk", "axis_clk", "ref_clk", "mgt_clk";
- clocks = <&axi_clk>, <&axi_clk>, <&pl_enet_ref_clk>, <&mgt_clk>;

-XILINX GMIITORGMII Converter Driver Device Tree Bindings
---------------------------------------------------------
-
-The Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media
-Independent Interface (RGMII) core provides the RGMII between RGMII-compliant
-Ethernet physical media devices (PHY) and the Gigabit Ethernet controller.
-This core can be used in all three modes of operation(10/100/1000 Mb/s).
-The Management Data Input/Output (MDIO) interface is used to configure the
-Speed of operation. This core can switch dynamically between the three
-Different speed modes by configuring the conveter register through mdio write.
-
-This converter sits between the ethernet MAC and the external phy.
-MAC <==> GMII2RGMII <==> RGMII_PHY
-
-For more details about mdio please refer phy.txt file in the same directory.
-
-Required properties:
-- compatible : Should be "xlnx,gmii-to-rgmii-1.0"
-- reg : The ID number for the phy, usually a small integer
-- phy-handle : Should point to the external phy device.
- See ethernet.txt file in the same directory.
-
-Example:
- mdio {
- #address-cells = <1>;
- #size-cells = <0>;
- phy: ethernet-phy@0 {
- ......
- };
- gmiitorgmii: gmiitorgmii@8 {
- compatible = "xlnx,gmii-to-rgmii-1.0";
- reg = <8>;
- phy-handle = <&phy>;
- };
- };

+title: AXI 1G/2.5G Ethernet Subsystem
+
+description: |
+ Also called AXI 1G/2.5G Ethernet Subsystem, the xilinx axi ethernet IP core
+ provides connectivity to an external ethernet PHY supporting different
+ interfaces: MII, GMII, RGMII, SGMII, 1000BaseX. It also includes two
+ segments of memory for buffering TX and RX, as well as the capability of
+ offloading TX/RX checksum calculation off the processor.
+
+ Management configuration is done through the AXI interface, while payload is
+ sent and received through means of an AXI DMA controller. This driver
+ includes the DMA driver code, so this driver is incompatible with AXI DMA
+ driver.

-==============================================================================
-NUMA binding description.
-==============================================================================
-
-==============================================================================
-1 - Introduction
-==============================================================================
-
-Systems employing a Non Uniform Memory Access (NUMA) architecture contain
-collections of hardware resources including processors, memory, and I/O buses,
-that comprise what is commonly known as a NUMA node.
-Processor accesses to memory within the local NUMA node is generally faster
-than processor accesses to memory outside of the local NUMA node.
-DT defines interfaces that allow the platform to convey NUMA node
-topology information to OS.
-
-==============================================================================
-2 - numa-node-id
-==============================================================================
-
-For the purpose of identification, each NUMA node is associated with a unique
-token known as a node id. For the purpose of this binding
-a node id is a 32-bit integer.
-
-A device node is associated with a NUMA node by the presence of a
-numa-node-id property which contains the node id of the device.
-
-Example:
- /* numa node 0 */
- numa-node-id = <0>;
-
- /* numa node 1 */
- numa-node-id = <1>;
-
-==============================================================================
-3 - distance-map
-==============================================================================
-
-The optional device tree node distance-map describes the relative
-distance (memory latency) between all numa nodes.
-
-- compatible : Should at least contain "numa-distance-map-v1".
-
-- distance-matrix
- This property defines a matrix to describe the relative distances
- between all numa nodes.
- It is represented as a list of node pairs and their relative distance.
-
- Note:
- 1. Each entry represents distance from first node to second node.
- The distances are equal in either direction.
- 2. The distance from a node to self (local distance) is represented
- with value 10 and all internode distance should be represented with
- a value greater than 10.
- 3. distance-matrix should have entries in lexicographical ascending
- order of nodes.
- 4. There must be only one device node distance-map which must
- reside in the root node.
- 5. If the distance-map node is not present, a default
- distance-matrix is used.
-
-Example:
- 4 nodes connected in mesh/ring topology as below,
-
- 0_______20______1
- | |
- | |
- 20 20
- | |
- | |
- |_______________|
- 3 20 2
-
- if relative distance for each hop is 20,
- then internode distance would be,
- 0 -> 1 = 20
- 1 -> 2 = 20
- 2 -> 3 = 20
- 3 -> 0 = 20
- 0 -> 2 = 40
- 1 -> 3 = 40
-
- and dt presentation for this distance matrix is,
-
- distance-map {
- compatible = "numa-distance-map-v1";
- distance-matrix = <0 0 10>,
- <0 1 20>,
- <0 2 40>,
- <0 3 20>,
- <1 0 20>,
- <1 1 10>,
- <1 2 20>,
- <1 3 40>,
- <2 0 40>,
- <2 1 20>,
- <2 2 10>,
- <2 3 20>,
- <3 0 20>,
- <3 1 40>,
- <3 2 20>,
- <3 3 10>;
- };
-
-==============================================================================
-4 - Empty memory nodes
-==============================================================================
-
-Empty memory nodes, which no memory resides in, are allowed. There are no
-device nodes for these empty memory nodes. However, the NUMA node IDs and
-distance maps are still valid and memory may be added into them through
-hotplug afterwards.
-
-Example:
-
- memory@0 {
- device_type = "memory";
- reg = <0x0 0x0 0x0 0x80000000>;
- numa-node-id = <0>;
- };
-
- memory@80000000 {
- device_type = "memory";
- reg = <0x0 0x80000000 0x0 0x80000000>;
- numa-node-id = <1>;
- };
-
- /* Empty memory node 2 and 3 */
- distance-map {
- compatible = "numa-distance-map-v1";

-title: U-Boot environment variables
-
-description: |
- U-Boot uses environment variables to store device parameters and
- configuration. They may be used for booting process, setup or keeping end user
- info.
-
- Data is stored using U-Boot specific formats (variant specific header and NUL
- separated key-value pairs).
-
- Environment data can be stored on various storage entities, e.g.:
- 1. Raw flash partition
- 2. UBI volume
-
- This binding allows marking storage device (as containing env data) and
- specifying used format.
-
- Right now only flash partition case is covered but it may be extended to e.g.
- UBI volumes in the future.
-
- Variables can be defined as NVMEM device subnodes.

-Texas Instruments OMAP compatible OPP supply description
-
-OMAP5, DRA7, and AM57 family of SoCs have Class0 AVS eFuse registers which
-contain data that can be used to adjust voltages programmed for some of their
-supplies for more efficient operation. This binding provides the information
-needed to read these values and use them to program the main regulator during
-an OPP transitions.
-
-Also, some supplies may have an associated vbb-supply which is an Adaptive Body
-Bias regulator which much be transitioned in a specific sequence with regards
-to the vdd-supply and clk when making an OPP transition. By supplying two
-regulators to the device that will undergo OPP transitions we can make use
-of the multi regulator binding that is part of the OPP core described here [1]
-to describe both regulators needed by the platform.
-
-[1] Documentation/devicetree/bindings/opp/opp-v2.yaml
-
-Required Properties for Device Node:
-- vdd-supply: phandle to regulator controlling VDD supply
-- vbb-supply: phandle to regulator controlling Body Bias supply
- (Usually Adaptive Body Bias regulator)
-
-Required Properties for opp-supply node:
-- compatible: Should be one of:
- "ti,omap-opp-supply" - basic OPP supply controlling VDD and VBB
- "ti,omap5-opp-supply" - OMAP5+ optimized voltages in efuse(class0)VDD
- along with VBB
- "ti,omap5-core-opp-supply" - OMAP5+ optimized voltages in efuse(class0) VDD
- but no VBB.
-- reg: Address and length of the efuse register set for the device (mandatory
- only for "ti,omap5-opp-supply")
-- ti,efuse-settings: An array of u32 tuple items providing information about
- optimized efuse configuration. Each item consists of the following:
- volt: voltage in uV - reference voltage (OPP voltage)
- efuse_offseet: efuse offset from reg where the optimized voltage is stored.
-- ti,absolute-max-voltage-uv: absolute maximum voltage for the OPP supply.
-
-Example:
-
-/* Device Node (CPU) */
-cpus {
- cpu0: cpu@0 {
- device_type = "cpu";
-
- ...
-
- vdd-supply = <&vcc>;
- vbb-supply = <&abb_mpu>;

-* Bus Enumeration by Freescale PCI-X Agent
-
-Typically any Freescale PCI-X bridge hardware strapped into Agent mode
-is prevented from enumerating the bus. The PrPMC form-factor requires
-all mezzanines to be PCI-X Agents, but one per system may still
-enumerate the bus.
-
-The property defined below will allow a PCI-X bridge to be used for bus
-enumeration despite being strapped into Agent mode.
-
-Required properties:
-- fsl,pci-agent-force-enum : There is no value associated with this
- property. The property itself is treated as a boolean.
-
-Example:
-
- /* PCI-X bridge known to be PrPMC Monarch */
- pci0: pci@ef008000 {
- fsl,pci-agent-force-enum;
- #interrupt-cells = <1>;
- #size-cells = <2>;
- #address-cells = <3>;

-Freescale Layerscape PCIe controller
-
-This PCIe host controller is based on the Synopsys DesignWare PCIe IP
-and thus inherits all the common properties defined in snps,dw-pcie.yaml.
-
-This controller derives its clocks from the Reset Configuration Word (RCW)
-which is used to describe the PLL settings at the time of chip-reset.
-
-Also as per the available Reference Manuals, there is no specific 'version'
-register available in the Freescale PCIe controller register set,
-which can allow determining the underlying DesignWare PCIe controller version
-information.
-
-Required properties:
-- compatible: should contain the platform identifier such as:
- RC mode:
- "fsl,ls1021a-pcie"
- "fsl,ls2080a-pcie", "fsl,ls2085a-pcie"
- "fsl,ls2088a-pcie"
- "fsl,ls1088a-pcie"
- "fsl,ls1046a-pcie"
- "fsl,ls1043a-pcie"
- "fsl,ls1012a-pcie"
- "fsl,ls1028a-pcie"
- EP mode:
- "fsl,ls1028a-pcie-ep", "fsl,ls-pcie-ep"
- "fsl,ls1046a-pcie-ep", "fsl,ls-pcie-ep"
- "fsl,ls1088a-pcie-ep", "fsl,ls-pcie-ep"
- "fsl,ls2088a-pcie-ep", "fsl,ls-pcie-ep"
- "fsl,lx2160ar2-pcie-ep", "fsl,ls-pcie-ep"
-- reg: base addresses and lengths of the PCIe controller register blocks.
-- interrupts: A list of interrupt outputs of the controller. Must contain an
- entry for each entry in the interrupt-names property.
-- interrupt-names: It could include the following entries:
- "aer": Used for interrupt line which reports AER events when
- non MSI/MSI-X/INTx mode is used
- "pme": Used for interrupt line which reports PME events when
- non MSI/MSI-X/INTx mode is used
- "intr": Used for SoCs(like ls2080a, lx2160a, ls2080a, ls2088a, ls1088a)
- which has a single interrupt line for miscellaneous controller
- events(could include AER and PME events).
-- fsl,pcie-scfg: Must include two entries.
- The first entry must be a link to the SCFG device node
- The second entry is the physical PCIe controller index starting from '0'.
- This is used to get SCFG PEXN registers
-- dma-coherent: Indicates that the hardware IP block can ensure the coherency
- of the data transferred from/to the IP block. This can avoid the software
- cache flush/invalid actions, and improve the performance significantly.
-
-Optional properties:
-- big-endian: If the PEX_LUT and PF register block is in big-endian, specify
- this property.
-
-Example:
-
- pcie@3400000 {
- compatible = "fsl,ls1088a-pcie";
- reg = <0x00 0x03400000 0x0 0x00100000>, /* controller registers */

+
+ * w is the 'target ID' value for the MBus window

-MediaTek Gen2 PCIe controller
-
-Required properties:
-- compatible: Should contain one of the following strings:
- "mediatek,mt2701-pcie"
- "mediatek,mt2712-pcie"
- "mediatek,mt7622-pcie"
- "mediatek,mt7623-pcie"
- "mediatek,mt7629-pcie"
- "airoha,en7523-pcie"
-- device_type: Must be "pci"
-- reg: Base addresses and lengths of the root ports.
-- reg-names: Names of the above areas to use during resource lookup.
-- #address-cells: Address representation for root ports (must be 3)
-- #size-cells: Size representation for root ports (must be 2)
-- clocks: Must contain an entry for each entry in clock-names.
- See ../clocks/clock-bindings.txt for details.
-- clock-names:
- Mandatory entries:
- - sys_ckN :transaction layer and data link layer clock
- Required entries for MT2701/MT7623:
- - free_ck :for reference clock of PCIe subsys
- Required entries for MT2712/MT7622:
- - ahb_ckN :AHB slave interface operating clock for CSR access and RC
- initiated MMIO access
- Required entries for MT7622:
- - axi_ckN :application layer MMIO channel operating clock
- - aux_ckN :pe2_mac_bridge and pe2_mac_core operating clock when
- pcie_mac_ck/pcie_pipe_ck is turned off
- - obff_ckN :OBFF functional block operating clock
- - pipe_ckN :LTSSM and PHY/MAC layer operating clock
- where N starting from 0 to one less than the number of root ports.
-- phys: List of PHY specifiers (used by generic PHY framework).
-- phy-names : Must be "pcie-phy0", "pcie-phy1", "pcie-phyN".. based on the
- number of PHYs as specified in *phys* property.
-- power-domains: A phandle and power domain specifier pair to the power domain
- which is responsible for collapsing and restoring power to the peripheral.
-- bus-range: Range of bus numbers associated with this controller.
-- ranges: Ranges for the PCI memory and I/O regions.
-
-Required properties for MT7623/MT2701:
-- #interrupt-cells: Size representation for interrupts (must be 1)
-- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties
- Please refer to the standard PCI bus binding document for a more detailed
- explanation.
-- resets: Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names: Must be "pcie-rst0", "pcie-rst1", "pcie-rstN".. based on the
- number of root ports.
-
-Required properties for MT2712/MT7622/MT7629:
--interrupts: A list of interrupt outputs of the controller, must have one
- entry for each PCIe port
-- interrupt-names: Must include the following entries:
- - "pcie_irq": The interrupt that is asserted when an MSI/INTX is received
-- linux,pci-domain: PCI domain ID. Should be unique for each host controller
-
-In addition, the device tree node must have sub-nodes describing each
-PCIe port interface, having the following mandatory properties:
-
-Required properties:
-- device_type: Must be "pci"
-- reg: Only the first four bytes are used to refer to the correct bus number
- and device number.
-- #address-cells: Must be 3
-- #size-cells: Must be 2
-- #interrupt-cells: Must be 1
-- interrupt-map-mask and interrupt-map: Standard PCI IRQ mapping properties
- Please refer to the standard PCI bus binding document for a more detailed
- explanation.
-- ranges: Sub-ranges distributed from the PCIe controller node. An empty
- property is sufficient.

-* Marvell EBU PCIe interfaces
-
-Mandatory properties:
-
-- compatible: one of the following values:
- marvell,armada-370-pcie
- marvell,armada-xp-pcie
- marvell,dove-pcie
- marvell,kirkwood-pcie
-- #address-cells, set to <3>
-- #size-cells, set to <2>
-- #interrupt-cells, set to <1>
-- bus-range: PCI bus numbers covered
-- device_type, set to "pci"
-- ranges: ranges describing the MMIO registers to control the PCIe
- interfaces, and ranges describing the MBus windows needed to access
- the memory and I/O regions of each PCIe interface.
-- msi-parent: Link to the hardware entity that serves as the Message
- Signaled Interrupt controller for this PCI controller.
-
-The ranges describing the MMIO registers have the following layout:
-
- 0x82000000 0 r MBUS_ID(0xf0, 0x01) r 0 s
-
-where:
-
- * r is a 32-bits value that gives the offset of the MMIO
- registers of this PCIe interface, from the base of the internal
- registers.
-
- * s is a 32-bits value that give the size of this MMIO
- registers area. This range entry translates the '0x82000000 0 r' PCI
- address into the 'MBUS_ID(0xf0, 0x01) r' CPU address, which is part
- of the internal register window (as identified by MBUS_ID(0xf0,
- 0x01)).
-
-The ranges describing the MBus windows have the following layout:
-
- 0x8t000000 s 0 MBUS_ID(w, a) 0 1 0
-
-where:
-
- * t is the type of the MBus window (as defined by the standard PCI DT
- bindings), 1 for I/O and 2 for memory.
-
- * s is the PCI slot that corresponds to this PCIe interface
-
- * w is the 'target ID' value for the MBus window
-
- * a the 'attribute' value for the MBus window.
-
-Since the location and size of the different MBus windows is not fixed in
-hardware, and only determined in runtime, those ranges cover the full first
-4 GB of the physical address space, and do not translate into a valid CPU
-address.
-
-In addition, the device tree node must have sub-nodes describing each
-PCIe interface, having the following mandatory properties:
-
-- reg: used only for interrupt mapping, so only the first four bytes
- are used to refer to the correct bus number and device number.
-- assigned-addresses: reference to the MMIO registers used to control
- this PCIe interface.
-- clocks: the clock associated to this PCIe interface
-- marvell,pcie-port: the physical PCIe port number
-- status: either "disabled" or "okay"
-- device_type, set to "pci"
-- #address-cells, set to <3>
-- #size-cells, set to <2>
-- #interrupt-cells, set to <1>
-- ranges, translating the MBus windows ranges of the parent node into
- standard PCI addresses.
-- interrupt-map-mask and interrupt-map, standard PCI properties to
- define the mapping of the PCIe interface to interrupt numbers.
-
-and the following optional properties:
-- marvell,pcie-lane: the physical PCIe lane number, for ports having
- multiple lanes. If this property is not found, we assume that the
- value is 0.
-- num-lanes: number of SerDes PCIe lanes for this link (1 or 4)
-- reset-gpios: optional GPIO to PERST#
-- reset-delay-us: delay in us to wait after reset de-assertion, if not
- specified will default to 100ms, as required by the PCIe specification.
-- interrupt-names: list of interrupt names, supported are:
- - "intx" - interrupt line triggered by one of the legacy interrupt
-- interrupts or interrupts-extended: List of the interrupt sources which
- corresponding to the "interrupt-names". If non-empty then also additional
- 'interrupt-controller' subnode must be defined.

+ A PCI Endpoint (EP) can use MSI as a doorbell function. This is achieved by

-This document describes the generic device tree binding for describing the
-relationship between PCI(e) devices and IOMMU(s).
-
-Each PCI(e) device under a root complex is uniquely identified by its Requester
-ID (AKA RID). A Requester ID is a triplet of a Bus number, Device number, and
-Function number.
-
-For the purpose of this document, when treated as a numeric value, a RID is
-formatted such that:
-
-* Bits [15:8] are the Bus number.
-* Bits [7:3] are the Device number.
-* Bits [2:0] are the Function number.
-* Any other bits required for padding must be zero.
-
-IOMMUs may distinguish PCI devices through sideband data derived from the
-Requester ID. While a given PCI device can only master through one IOMMU, a
-root complex may split masters across a set of IOMMUs (e.g. with one IOMMU per
-bus).
-
-The generic 'iommus' property is insufficient to describe this relationship,
-and a mechanism is required to map from a PCI device to its IOMMU and sideband
-data.
-
-For generic IOMMU bindings, see
-Documentation/devicetree/bindings/iommu/iommu.txt.

-This document describes the generic device tree binding for describing the
-relationship between PCI devices and MSI controllers.
-
-Each PCI device under a root complex is uniquely identified by its Requester ID
-(AKA RID). A Requester ID is a triplet of a Bus number, Device number, and
-Function number.
-
-For the purpose of this document, when treated as a numeric value, a RID is
-formatted such that:
-
-* Bits [15:8] are the Bus number.
-* Bits [7:3] are the Device number.
-* Bits [2:0] are the Function number.
-* Any other bits required for padding must be zero.
-
-MSIs may be distinguished in part through the use of sideband data accompanying
-writes. In the case of PCI devices, this sideband data may be derived from the
-Requester ID. A mechanism is required to associate a device with both the MSI
-controllers it can address, and the sideband data that will be associated with
-its writes to those controllers.
-
-For generic MSI bindings, see
-Documentation/devicetree/bindings/interrupt-controller/msi.txt.
-
-
-PCI root complex
-================
-
-Optional properties
--------------------
-
-- msi-map: Maps a Requester ID to an MSI controller and associated
- msi-specifier data. The property is an arbitrary number of tuples of
- (rid-base,msi-controller,msi-base,length), where:
-
- * rid-base is a single cell describing the first RID matched by the entry.
-
- * msi-controller is a single phandle to an MSI controller
-
- * msi-base is an msi-specifier describing the msi-specifier produced for the
- first RID matched by the entry.
-
- * length is a single cell describing how many consecutive RIDs are matched
- following the rid-base.
-
- Any RID r in the interval [rid-base, rid-base + length) is associated with
- the listed msi-controller, with the msi-specifier (r - rid-base + msi-base).
-
-- msi-map-mask: A mask to be applied to each Requester ID prior to being mapped
- to an msi-specifier per the msi-map property.
-
-- msi-parent: Describes the MSI parent of the root complex itself. Where
- the root complex and MSI controller do not pass sideband data with MSI
- writes, this property may be used to describe the MSI controller(s)
- used by PCI devices under the root complex, if defined as such in the
- binding for the root complex.

-PCI bus bridges have standardized Device Tree bindings:
-
-PCI Bus Binding to: IEEE Std 1275-1994
-https://www.devicetree.org/open-firmware/bindings/pci/pci2_1.pdf
-
-And for the interrupt mapping part:
-
-Open Firmware Recommended Practice: Interrupt Mapping
-https://www.devicetree.org/open-firmware/practice/imap/imap0_9d.pdf
-
-Additionally to the properties specified in the above standards a host bridge
-driver implementation may support the following properties:
-
-- linux,pci-domain:
- If present this property assigns a fixed PCI domain number to a host bridge,
- otherwise an unstable (across boots) unique number will be assigned.
- It is required to either not set this property at all or set it for all
- host bridges in the system, otherwise potentially conflicting domain numbers
- may be assigned to root buses behind different host bridges. The domain
- number for each host bridge in the system must be unique.
-- max-link-speed:
- If present this property specifies PCI gen for link capability. Host
- drivers could add this as a strategy to avoid unnecessary operation for
- unsupported link speed, for instance, trying to do training for
- unsupported link speed, etc. Must be '4' for gen4, '3' for gen3, '2'
- for gen2, and '1' for gen1. Any other values are invalid.
-- reset-gpios:
- If present this property specifies PERST# GPIO. Host drivers can parse the
- GPIO and apply fundamental reset to endpoints.
-- supports-clkreq:
- If present this property specifies that CLKREQ signal routing exists from
- root port to downstream device and host bridge drivers can do programming
- which depends on CLKREQ signal existence. For example, programming root port
- not to advertise ASPM L1 Sub-States support if there is no CLKREQ signal.
-
-PCI-PCI Bridge properties
--------------------------
-
-PCIe root ports and switch ports may be described explicitly in the device
-tree, as children of the host bridge node. Even though those devices are
-discoverable by probing, it might be necessary to describe properties that
-aren't provided by standard PCIe capabilities.
-
-Required properties:
-
-- reg:
- Identifies the PCI-PCI bridge. As defined in the IEEE Std 1275-1994
- document, it is a five-cell address encoded as (phys.hi phys.mid
- phys.lo size.hi size.lo). phys.hi should contain the device's BDF as
- 0b00000000 bbbbbbbb dddddfff 00000000. The other cells should be zero.
-
- The bus number is defined by firmware, through the standard bridge
- configuration mechanism. If this port is a switch port, then firmware
- allocates the bus number and writes it into the Secondary Bus Number
- register of the bridge directly above this port. Otherwise, the bus
- number of a root port is the first number in the bus-range property,
- defaulting to zero.
-
- If firmware leaves the ARI Forwarding Enable bit set in the bridge
- above this port, then phys.hi contains the 8-bit function number as
- 0b00000000 bbbbbbbb ffffffff 00000000. Note that the PCIe specification
- recommends that firmware only leaves ARI enabled when it knows that the
- OS is ARI-aware.
-
-Optional properties:
-
-- external-facing:
- When present, the port is external-facing. All bridges and endpoints
- downstream of this port are external to the machine. The OS can, for
- example, use this information to identify devices that cannot be
- trusted with relaxed DMA protection, as users could easily attach
- malicious devices to this port.
-
-Example:
-
-pcie@10000000 {
- compatible = "pci-host-ecam-generic";
- ...
- pcie@0008 {
- /* Root port 00:01.0 is external-facing */
- reg = <0x00000800 0 0 0 0>;
- external-facing;
- };
-};

-V3 Semiconductor V360 EPC PCI bridge
-
-This bridge is found in the ARM Integrator/AP (Application Platform)
-
-Required properties:
-- compatible: should be one of:
- "v3,v360epc-pci"
- "arm,integrator-ap-pci", "v3,v360epc-pci"
-- reg: should contain two register areas:
- first the base address of the V3 host bridge controller, 64KB
- second the configuration area register space, 16MB
-- interrupts: should contain a reference to the V3 error interrupt
- as routed on the system.
-- bus-range: see pci.txt
-- ranges: this follows the standard PCI bindings in the IEEE Std
- 1275-1994 (see pci.txt) with the following restriction:
- - The non-prefetchable and prefetchable memory windows must
- each be exactly 256MB (0x10000000) in size.
- - The prefetchable memory window must be immediately adjacent
- to the non-prefetcable memory window
-- dma-ranges: three ranges for the inbound memory region. The ranges must
- be aligned to a 1MB boundary, and may be 1MB, 2MB, 4MB, 8MB, 16MB, 32MB,
- 64MB, 128MB, 256MB, 512MB, 1GB or 2GB in size. The memory should be marked
- as pre-fetchable. Two ranges are supported by the hardware.
-
-Integrator-specific required properties:
-- syscon: should contain a link to the syscon device node, since
- on the Integrator, some registers in the syscon are required to
- operate the V3 host bridge.
-
-Example:

-* APM X-Gene SoC PMU bindings
-
-This is APM X-Gene SoC PMU (Performance Monitoring Unit) module.
-The following PMU devices are supported:
-
- L3C - L3 cache controller
- IOB - IO bridge
- MCB - Memory controller bridge
- MC - Memory controller
-
-The following section describes the SoC PMU DT node binding.
-
-Required properties:
-- compatible : Shall be "apm,xgene-pmu" for revision 1 or
- "apm,xgene-pmu-v2" for revision 2.
-- regmap-csw : Regmap of the CPU switch fabric (CSW) resource.
-- regmap-mcba : Regmap of the MCB-A (memory bridge) resource.
-- regmap-mcbb : Regmap of the MCB-B (memory bridge) resource.
-- reg : First resource shall be the CPU bus PMU resource.
-- interrupts : Interrupt-specifier for PMU IRQ.
-
-Required properties for L3C subnode:
-- compatible : Shall be "apm,xgene-pmu-l3c".
-- reg : First resource shall be the L3C PMU resource.
-
-Required properties for IOB subnode:
-- compatible : Shall be "apm,xgene-pmu-iob".
-- reg : First resource shall be the IOB PMU resource.
-
-Required properties for MCB subnode:
-- compatible : Shall be "apm,xgene-pmu-mcb".
-- reg : First resource shall be the MCB PMU resource.
-- enable-bit-index : The bit indicates if the according MCB is enabled.
-
-Required properties for MC subnode:
-- compatible : Shall be "apm,xgene-pmu-mc".
-- reg : First resource shall be the MC PMU resource.
-- enable-bit-index : The bit indicates if the according MC is enabled.

-Rockchip EMMC PHY
------------------------
-
-Required properties:
- - compatible: rockchip,rk3399-emmc-phy
- - #phy-cells: must be 0
- - reg: PHY register address offset and length in "general
- register files"
-
-Optional properties:
- - clock-names: Should contain "emmcclk". Although this is listed as optional
- (because most boards can get basic functionality without having
- access to it), it is strongly suggested.
- See ../clock/clock-bindings.txt for details.
- - clocks: Should have a phandle to the card clock exported by the SDHCI driver.
- - drive-impedance-ohm: Specifies the drive impedance in Ohm.
- Possible values are 33, 40, 50, 66 and 100.
- If not set, the default value of 50 will be applied.
- - rockchip,enable-strobe-pulldown: Enable internal pull-down for the strobe
- line. If not set, pull-down is not used.
- - rockchip,output-tapdelay-select: Specifies the phyctrl_otapdlysec register.
- If not set, the register defaults to 0x4.
- Maximum value 0xf.
-
-Example:
-
-
-grf: syscon@ff770000 {
- compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd";

-Actions Semi S700 Pin Controller
-
-This binding describes the pin controller found in the S700 SoC.
-
-Required Properties:
-
-- compatible: Should be "actions,s700-pinctrl"
-- reg: Should contain the register base address and size of
- the pin controller.
-- clocks: phandle of the clock feeding the pin controller
-- gpio-controller: Marks the device node as a GPIO controller.
-- gpio-ranges: Specifies the mapping between gpio controller and
- pin-controller pins.
-- #gpio-cells: Should be two. The first cell is the gpio pin number
- and the second cell is used for optional parameters.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt. Shall be set to 2. The first cell
- defines the interrupt number, the second encodes
- the trigger flags described in
- bindings/interrupt-controller/interrupts.txt
-- interrupts: The interrupt outputs from the controller. There is one GPIO
- interrupt per GPIO bank. The number of interrupts listed depends
- on the number of GPIO banks on the SoC. The interrupts must be
- ordered by bank, starting with bank 0.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-The pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those group(s), and various pin configuration
-parameters, such as pull-up, drive strength, etc.
-
-PIN CONFIGURATION NODES:
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function.
-
-Pinmux functions are available only for the pin groups while pinconf
-parameters are available for both pin groups and individual pins.
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pin configuration subnode:
-

-Actions Semi S900 Pin Controller
-
-This binding describes the pin controller found in the S900 SoC.
-
-Required Properties:
-
-- compatible: Should be "actions,s900-pinctrl"
-- reg: Should contain the register base address and size of
- the pin controller.
-- clocks: phandle of the clock feeding the pin controller
-- gpio-controller: Marks the device node as a GPIO controller.
-- gpio-ranges: Specifies the mapping between gpio controller and
- pin-controller pins.
-- #gpio-cells: Should be two. The first cell is the gpio pin number
- and the second cell is used for optional parameters.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt. Shall be set to 2. The first cell
- defines the interrupt number, the second encodes
- the trigger flags described in
- bindings/interrupt-controller/interrupts.txt
-- interrupts: The interrupt outputs from the controller. There is one GPIO
- interrupt per GPIO bank. The number of interrupts listed depends
- on the number of GPIO banks on the SoC. The interrupts must be
- ordered by bank, starting with bank 0.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-The pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those group(s), and various pin configuration
-parameters, such as pull-up, drive strength, etc.
-
-PIN CONFIGURATION NODES:
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function.
-
-Pinmux functions are available only for the pin groups while pinconf
-parameters are available for both pin groups and individual pins.
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pin configuration subnode:
-
-Required Properties:

-* Atmel AT91 Pinmux Controller
-
-The AT91 Pinmux Controller, enables the IC
-to share one PAD to several functional blocks. The sharing is done by
-multiplexing the PAD input/output signals. For each PAD there are up to
-8 muxing options (called periph modes). Since different modules require
-different PAD settings (like pull up, keeper, etc) the controller controls
-also the PAD settings parameters.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-Atmel AT91 pin configuration node is a node of a group of pins which can be
-used for a specific device or function. This node represents both mux and config
-of the pins in that group. The 'pins' selects the function mode(also named pin
-mode) this pin can work on and the 'config' configures various pad settings
-such as pull-up, multi drive, etc.
-
-Required properties for iomux controller:
-- compatible: "atmel,at91rm9200-pinctrl" or "atmel,at91sam9x5-pinctrl"
- or "atmel,sama5d3-pinctrl" or "microchip,sam9x60-pinctrl"
-- atmel,mux-mask: array of mask (periph per bank) to describe if a pin can be
- configured in this periph mode. All the periph and bank need to be describe.
-
-How to create such array:
-
-Each column will represent the possible peripheral of the pinctrl
-Each line will represent a pio bank
-
-Take an example on the 9260
-Peripheral: 2 ( A and B)
-Bank: 3 (A, B and C)
-=>
-
- /* A B */
- 0xffffffff 0xffc00c3b /* pioA */
- 0xffffffff 0x7fff3ccf /* pioB */
- 0xffffffff 0x007fffff /* pioC */
-
-For each peripheral/bank we will describe in a u32 if a pin can be
-configured in it by putting 1 to the pin bit (1 << pin)
-
-Let's take the pioA on peripheral B
-From the datasheet Table 10-2.

-Required properties for pin configuration node:
-- atmel,pins: 4 integers array, represents a group of pins mux and config
- setting. The format is atmel,pins = <PIN_BANK PIN_BANK_NUM PERIPH CONFIG>.
- The PERIPH 0 means gpio, PERIPH 1 is periph A, PERIPH 2 is periph B...
- PIN_BANK 0 is pioA, PIN_BANK 1 is pioB...
-
-Bits used for CONFIG:
-PULL_UP (1 << 0): indicate this pin needs a pull up.
-MULTIDRIVE (1 << 1): indicate this pin needs to be configured as multi-drive.
- Multi-drive is equivalent to open-drain type output.
-DEGLITCH (1 << 2): indicate this pin needs deglitch.
-PULL_DOWN (1 << 3): indicate this pin needs a pull down.
-DIS_SCHMIT (1 << 4): indicate this pin needs to the disable schmitt trigger.
-DRIVE_STRENGTH (3 << 5): indicate the drive strength of the pin using the
- following values:
- 00 - No change (reset state value kept)
- 01 - Low
- 10 - Medium
- 11 - High
-OUTPUT (1 << 7): indicate this pin need to be configured as an output.
-OUTPUT_VAL (1 << 8): output val (1 = high, 0 = low)
-SLEWRATE (1 << 9): slew rate of the pin: 0 = disable, 1 = enable
-DEBOUNCE (1 << 16): indicate this pin needs debounce.
-DEBOUNCE_VAL (0x3fff << 17): debounce value.
-
-NOTE:
-Some requirements for using atmel,at91rm9200-pinctrl binding:
-1. We have pin function node defined under at91 controller node to represent
- what pinmux functions this SoC supports.
-2. The driver can use the function node's name and pin configuration node's
- name describe the pin function and group hierarchy.
- For example, Linux at91 pinctrl driver takes the function node's name
- as the function name and pin configuration node's name as group name to
- create the map table.
-3. Each pin configuration node should have a phandle, devices can set pins
- configurations by referring to the phandle of that pin configuration node.
-4. The gpio controller must be describe in the pinctrl simple-bus.
-
-For each bank the required properties are:
-- compatible: "atmel,at91sam9x5-gpio" or "atmel,at91rm9200-gpio" or
- "microchip,sam9x60-gpio"
-- reg: physical base address and length of the controller's registers
-- interrupts: interrupt outputs from the controller
-- interrupt-controller: marks the device node as an interrupt controller
-- #interrupt-cells: should be 2; refer to ../interrupt-controller/interrupts.txt
- for more details.
-- gpio-controller
-- #gpio-cells: should be 2; the first cell is the GPIO number and the second
- cell specifies GPIO flags as defined in <dt-bindings/gpio/gpio.h>.
-- clocks: bank clock

-* Pin-controller driver for the Marvell Berlin SoCs
-
-Pin control registers are part of both chip controller and system
-controller register sets. Pin controller nodes should be a sub-node of
-either the chip controller or system controller node. The pins
-controlled are organized in groups, so no actual pin information is
-needed.
-
-A pin-controller node should contain subnodes representing the pin group
-configurations, one per function. Each subnode has the group name and
-the muxing function used.
-
-Be aware the Marvell Berlin datasheets use the keyword 'mode' for what
-is called a 'function' in the pin-controller subsystem.
-
-Required properties:
-- compatible: should be one of:
- "marvell,berlin2-soc-pinctrl",
- "marvell,berlin2-system-pinctrl",
- "marvell,berlin2cd-soc-pinctrl",
- "marvell,berlin2cd-system-pinctrl",
- "marvell,berlin2q-soc-pinctrl",
- "marvell,berlin2q-system-pinctrl",
- "marvell,berlin4ct-avio-pinctrl",
- "marvell,berlin4ct-soc-pinctrl",
- "marvell,berlin4ct-system-pinctrl",
- "syna,as370-soc-pinctrl"
-
-Required subnode-properties:
-- groups: a list of strings describing the group names.
-- function: a string describing the function used to mux the groups.
-
-Example:
-
-sys_pinctrl: pin-controller {
- compatible = "marvell,berlin2q-system-pinctrl";
-
- uart0_pmux: uart0-pmux {
- groups = "GSM12";
- function = "uart0";
- };
-};
-
-&uart0 {
- pinctrl-0 = <&uart0_pmux>;
- pinctrl-names = "default";
-};

-Bitmain BM1880 Pin Controller
-
-This binding describes the pin controller found in the BM1880 SoC.
-
-Required Properties:
-
-- compatible: Should be "bitmain,bm1880-pinctrl"
-- reg: Offset and length of pinctrl space in SCTRL.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-The pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration for BM1880 SoC
-includes pinmux and various pin configuration parameters, such as pull-up,
-slew rate etc...
-
-Each configuration node can consist of multiple nodes describing the pinmux
-options. The name of each subnode is not important; all subnodes should be
-enumerated and processed purely based on their content.
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pinmux subnode:
-

-Broadcom BCM281xx Pin Controller
-
-This is a pin controller for the Broadcom BCM281xx SoC family, which includes
-BCM11130, BCM11140, BCM11351, BCM28145, and BCM28155 SoCs.
-
-=== Pin Controller Node ===
-
-Required Properties:
-
-- compatible: Must be "brcm,bcm11351-pinctrl"
-- reg: Base address of the PAD Controller register block and the size
- of the block.
-
-For example, the following is the bare minimum node:
-
- pinctrl@35004800 {
- compatible = "brcm,bcm11351-pinctrl";
- reg = <0x35004800 0x430>;
- };
-
-As a pin controller device, in addition to the required properties, this node
-should also contain the pin configuration nodes that client devices reference,
-if any.
-
-=== Pin Configuration Node ===
-
-Each pin configuration node is a sub-node of the pin controller node and is a
-container of an arbitrary number of subnodes, called pin group nodes in this
-document.
-
-Please refer to the pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the definition of a
-"pin configuration node".
-
-=== Pin Group Node ===
-
-A pin group node specifies the desired pin mux and/or pin configuration for an
-arbitrary number of pins. The name of the pin group node is optional and not
-used.
-
-A pin group node only affects the properties specified in the node, and has no
-effect on any properties that are omitted.
-
-The pin group node accepts a subset of the generic pin config properties. For
-details generic pin config properties, please refer to pinctrl-bindings.txt
-and <include/linux/pinctrl/pinconfig-generic.h>.
-
-Each pin controlled by this pin controller belong to one of three types:
-Standard, I2C, and HDMI. Each type accepts a different set of pin config
-properties. A list of pins and their types is provided below.
-
-Required Properties (applicable to all pins):
-
-- pins: Multiple strings. Specifies the name(s) of one or more pins to
- be configured by this node.
-
-Optional Properties (for standard pins):
-
-- function: String. Specifies the pin mux selection. Values
- must be one of: "alt1", "alt2", "alt3", "alt4"
-- input-schmitt-enable: No arguments. Enable schmitt-trigger mode.
-- input-schmitt-disable: No arguments. Disable schmitt-trigger mode.
-- bias-pull-up: No arguments. Pull up on pin.
-- bias-pull-down: No arguments. Pull down on pin.
-- bias-disable: No arguments. Disable pin bias.
-- slew-rate: Integer. Meaning depends on configured pin mux:
- *_SCL or *_SDA:
- 0: Standard(100kbps)& Fast(400kbps) mode
- 1: Highspeed (3.4Mbps) mode
- IC_DM or IC_DP:
- 0: normal slew rate
- 1: fast slew rate
- Otherwise:
- 0: fast slew rate
- 1: normal slew rate
-- input-enable: No arguments. Enable input (does not affect
- output.)
-- input-disable: No arguments. Disable input (does not affect
- output.)
-- drive-strength: Integer. Drive strength in mA. Valid values are
- 2, 4, 6, 8, 10, 12, 14, 16 mA.
-
-Optional Properties (for I2C pins):
-
-- function: String. Specifies the pin mux selection. Values
- must be one of: "alt1", "alt2", "alt3", "alt4"
-- bias-pull-up: Integer. Pull up strength in Ohm. There are 3
- pull-up resistors (1.2k, 1.8k, 2.7k) available
- in parallel for I2C pins, so the valid values
- are: 568, 720, 831, 1080, 1200, 1800, 2700 Ohm.
-- bias-disable: No arguments. Disable pin bias.
-- slew-rate: Integer. Meaning depends on configured pin mux:
- *_SCL or *_SDA:
- 0: Standard(100kbps)& Fast(400kbps) mode
- 1: Highspeed (3.4Mbps) mode
- IC_DM or IC_DP:
- 0: normal slew rate
- 1: fast slew rate
- Otherwise:
- 0: fast slew rate
- 1: normal slew rate
-- input-enable: No arguments. Enable input (does not affect
- output.)
-- input-disable: No arguments. Disable input (does not affect
- output.)
-
-Optional Properties (for HDMI pins):
-
-- function: String. Specifies the pin mux selection. Values
- must be one of: "alt1", "alt2", "alt3", "alt4"
-- slew-rate: Integer. Controls slew rate.
- 0: Standard(100kbps)& Fast(400kbps) mode
- 1: Highspeed (3.4Mbps) mode
-- input-enable: No arguments. Enable input (does not affect
- output.)
-- input-disable: No arguments. Disable input (does not affect
- output.)
-
-Example:
-// pin controller node
-pinctrl@35004800 {
- compatible = "brcm,bcm11351-pinctrl";
- reg = <0x35004800 0x430>;
-
- // pin configuration node
- dev_a_default: dev_a_active {
- //group node defining 1 standard pin
- grp_1 {
- pins = "std_pin1";
- function = "alt1";
- input-schmitt-enable;
- bias-disable;
- slew-rate = <1>;
- drive-strength = <4>;
- };
-
- // group node defining 2 I2C pins
- grp_2 {
- pins = "i2c_pin1", "i2c_pin2";
- function = "alt2";
- bias-pull-up = <720>;
- input-enable;
- };
-
- // group node defining 2 HDMI pins
- grp_3 {
- pins = "hdmi_pin1", "hdmi_pin2";
- function = "alt3";
- slew-rate = <1>;
- };
-
- // other pin group nodes
- ...
- };
-
- // other pin configuration nodes
- ...
-};
-
-In the example above, "dev_a_active" is a pin configuration node with a number
-of sub-nodes. In the pin group node "grp_1", one pin, "std_pin1", is defined in
-the "pins" property. Thus, the remaining properties in the "grp_1" node applies
-only to this pin, including the following settings:
- - setting pinmux to "alt1"
- - enabling schmitt-trigger (hystersis) mode
- - disabling pin bias
- - setting the slew-rate to 1
- - setting the drive strength to 4 mA
-Note that neither "input-enable" nor "input-disable" was specified - the pinctrl
-subsystem will therefore leave this property unchanged from whatever state it
-was in before applying these changes.
-
-The "pins" property in the pin group node "grp_2" specifies two pins -
-"i2c_pin1" and "i2c_pin2"; the remaining properties in this pin group node,
-therefore, applies to both of these pins. The properties include:
- - setting pinmux to "alt2"
- - setting pull-up resistance to 720 Ohm (ie. enabling 1.2k and 1.8k resistors
- in parallel)
- - enabling both pins' input
-"slew-rate" is not specified in this pin group node, so the slew-rate for these
-pins are left as-is.
-
-Finally, "grp_3" defines two HDMI pins. The following properties are applied to
-both pins:
- - setting pinmux to "alt3"
- - setting slew-rate to 1; for HDMI pins, this corresponds to the 3.4 Mbps
- Highspeed mode
-The input is neither enabled or disabled, and is left untouched.
-

-Broadcom BCM2835 GPIO (and pinmux) controller
-
-The BCM2835 GPIO module is a combined GPIO controller, (GPIO) interrupt
-controller, and pinmux/control device.
-
-Required properties:
-- compatible: "brcm,bcm2835-gpio"
-- compatible: should be one of:
- "brcm,bcm2835-gpio" - BCM2835 compatible pinctrl
- "brcm,bcm7211-gpio" - BCM7211 compatible pinctrl
- "brcm,bcm2711-gpio" - BCM2711 compatible pinctrl
- "brcm,bcm7211-gpio" - BCM7211 compatible pinctrl
-- reg: Should contain the physical address of the GPIO module's registers.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells : Should be two. The first cell is the pin number and the
- second cell is used to specify optional parameters:
- - bit 0 specifies polarity (0 for normal, 1 for inverted)
-- interrupts : The interrupt outputs from the controller. One interrupt per
- individual bank followed by the "all banks" interrupt. For BCM7211, an
- additional set of per-bank interrupt line and an "all banks" wake-up
- interrupt may be specified.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells : Should be 2.
- The first cell is the GPIO number.
- The second cell is used to specify flags:
- bits[3:0] trigger type and level flags:
- 1 = low-to-high edge triggered.
- 2 = high-to-low edge triggered.
- 4 = active high level-sensitive.
- 8 = active low level-sensitive.
- Valid combinations are 1, 2, 3, 4, 8.
-
-Please refer to ../gpio/gpio.txt for a general description of GPIO bindings.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-Each pin configuration node lists the pin(s) to which it applies, and one or
-more of the mux function to select on those pin(s), and pull-up/down
-configuration. Each subnode only affects those parameters that are explicitly
-listed. In other words, a subnode that lists only a mux function implies no
-information about any pull configuration. Similarly, a subnode that lists only
-a pul parameter implies no information about the mux function.
-
-The BCM2835 pin configuration and multiplexing supports the generic bindings.
-For details on each properties, you can refer to ./pinctrl-bindings.txt.
-
-Required sub-node properties:
- - pins
- - function
-
-Optional sub-node properties:
- - bias-disable
- - bias-pull-up
- - bias-pull-down
- - output-high
- - output-low
-
-Legacy pin configuration and multiplexing binding:
-*** (Its use is deprecated, use generic multiplexing and configuration
-bindings instead)
-
-Required subnode-properties:
-- brcm,pins: An array of cells. Each cell contains the ID of a pin. Valid IDs
- are the integer GPIO IDs; 0==GPIO0, 1==GPIO1, ... 53==GPIO53.
-
-Optional subnode-properties:
-- brcm,function: Integer, containing the function to mux to the pin(s):
- 0: GPIO in
- 1: GPIO out
- 2: alt5
- 3: alt4
- 4: alt0
- 5: alt1
- 6: alt2
- 7: alt3
-- brcm,pull: Integer, representing the pull-down/up to apply to the pin(s):
- 0: none
- 1: down
- 2: up
-
-Each of brcm,function and brcm,pull may contain either a single value which
-will be applied to all pins in brcm,pins, or 1 value for each entry in
-brcm,pins.
-
-Example:
-
- gpio: gpio {
- compatible = "brcm,bcm2835-gpio";
- reg = <0x2200000 0xb4>;
- interrupts = <2 17>, <2 19>, <2 18>, <2 20>;
-
- gpio-controller;
- #gpio-cells = <2>;
-
- interrupt-controller;
- #interrupt-cells = <2>;

-Broadcom iProc GPIO/PINCONF Controller
-
-Required properties:
-
-- compatible:
- "brcm,iproc-gpio" for the generic iProc based GPIO controller IP that
- supports full-featured pinctrl and GPIO functions used in various iProc
- based SoCs
-
- May contain an SoC-specific compatibility string to accommodate any
- SoC-specific features
-
- "brcm,cygnus-ccm-gpio", "brcm,cygnus-asiu-gpio", or
- "brcm,cygnus-crmu-gpio" for Cygnus SoCs
-
- "brcm,iproc-nsp-gpio" for the iProc NSP SoC that has drive strength support
- disabled
-
- "brcm,iproc-stingray-gpio" for the iProc Stingray SoC that has the general
- pinctrl support completely disabled in this IP block. In Stingray, a
- different IP block is used to handle pinctrl related functions
-
-- reg:
- Define the base and range of the I/O address space that contains SoC
-GPIO/PINCONF controller registers
-
-- ngpios:
- Total number of in-use slots in GPIO controller
-
-- #gpio-cells:
- Must be two. The first cell is the GPIO pin number (within the
-controller's pin space) and the second cell is used for the following:
- bit[0]: polarity (0 for active high and 1 for active low)
-
-- gpio-controller:
- Specifies that the node is a GPIO controller
-
-Optional properties:
-
-- interrupts:
- Interrupt ID
-
-- interrupt-controller:
- Specifies that the node is an interrupt controller
-
-- gpio-ranges:
- Specifies the mapping between gpio controller and pin-controllers pins.
- This requires 4 fields in cells defined as -
- 1. Phandle of pin-controller.
- 2. GPIO base pin offset.
- 3 Pin-control base pin offset.
- 4. number of gpio pins which are linearly mapped from pin base.
-
-Supported generic PINCONF properties in child nodes:
-
-- pins:
- The list of pins (within the controller's own pin space) that properties
-in the node apply to. Pin names are "gpio-<pin>"
-
-- bias-disable:
- Disable pin bias
-
-- bias-pull-up:
- Enable internal pull up resistor
-
-- bias-pull-down:
- Enable internal pull down resistor
-
-- drive-strength:
- Valid drive strength values include 2, 4, 6, 8, 10, 12, 14, 16 (mA)
-
-Example:
- gpio_ccm: gpio@1800a000 {
- compatible = "brcm,cygnus-ccm-gpio";

-* Freescale i.MX7ULP IOMUX Controller
-
-i.MX 7ULP has three IOMUXC instances: IOMUXC0 for M4 ports, IOMUXC1 for A7
-ports and IOMUXC DDR for DDR interface.
-
-Note:
-This binding doc is only for the IOMUXC1 support in A7 Domain and it only
-supports generic pin config.
-
-Please refer to fsl,imx-pinctrl.txt in this directory for common binding
-part and usage.
-
-Required properties:
-- compatible: "fsl,imx7ulp-iomuxc1".
-- fsl,pins: Each entry consists of 5 integers which represents the mux
- and config setting for one pin. The first 4 integers
- <mux_conf_reg input_reg mux_mode input_val> are specified
- using a PIN_FUNC_ID macro, which can be found in
- imx7ulp-pinfunc.h in the device tree source folder.
- The last integer CONFIG is the pad setting value like
- pull-up on this pin.
-
- Please refer to i.MX7ULP Reference Manual for detailed
- CONFIG settings.

-* Freescale MXS Pin Controller
-
-The pins controlled by mxs pin controller are organized in banks, each bank
-has 32 pins. Each pin has 4 multiplexing functions, and generally, the 4th
-function is GPIO. The configuration on the pins includes drive strength,
-voltage and pull-up.
-
-Required properties:
-- compatible: "fsl,imx23-pinctrl" or "fsl,imx28-pinctrl"
-- reg: Should contain the register physical address and length for the
- pin controller.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices.
-
-The node of mxs pin controller acts as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for
-a group of pins, and only affects those parameters that are explicitly listed.
-In other words, a subnode that describes a drive strength parameter implies no
-information about pull-up. For this reason, even seemingly boolean values are
-actually tristates in this binding: unspecified, off, or on. Unspecified is
-represented as an absent property, and off/on are represented as integer
-values 0 and 1.
-
-Those subnodes under mxs pin controller node will fall into two categories.
-One is to set up a group of pins for a function, both mux selection and pin
-configurations, and it's called group node in the binding document. The other
-one is to adjust the pin configuration for some particular pins that need a
-different configuration than what is defined in group node. The binding
-document calls this type of node config node.
-
-On mxs, there is no hardware pin group. The pin group in this binding only
-means a group of pins put together for particular peripheral to work in
-particular function, like SSP0 functioning as mmc0-8bit. That said, the
-group node should include all the pins needed for one function rather than
-having these pins defined in several group nodes. It also means each of
-"pinctrl-*" phandle in client device node should only have one group node
-pointed in there, while the phandle can have multiple config node referenced
-there to adjust configurations for some pins in the group.
-
-Required subnode-properties:
-- fsl,pinmux-ids: An integer array. Each integer in the array specify a pin
- with given mux function, with bank, pin and mux packed as below.
-
- [15..12] : bank number
- [11..4] : pin number
- [3..0] : mux selection
-
- This integer with mux selection packed is used as an entity by both group
- and config nodes to identify a pin. The mux selection in the integer takes
- effects only on group node, and will get ignored by driver with config node,
- since config node is only meant to set up pin configurations.
-
- Valid values for these integers are listed below.
-
-- reg: Should be the index of the group nodes for same function. This property
- is required only for group nodes, and should not be present in any config
- nodes.
-
-Optional subnode-properties:
-- fsl,drive-strength: Integer.
- 0: MXS_DRIVE_4mA
- 1: MXS_DRIVE_8mA
- 2: MXS_DRIVE_12mA
- 3: MXS_DRIVE_16mA
-- fsl,voltage: Integer.
- 0: MXS_VOLTAGE_LOW - 1.8 V
- 1: MXS_VOLTAGE_HIGH - 3.3 V
-- fsl,pull-up: Integer.
- 0: MXS_PULL_DISABLE - Disable the internal pull-up
- 1: MXS_PULL_ENABLE - Enable the internal pull-up
-
-Note that when enabling the pull-up, the internal pad keeper gets disabled.
-Also, some pins doesn't have a pull up, in that case, setting the fsl,pull-up
-will only disable the internal pad keeper.
-
-Examples:
-
-pinctrl@80018000 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "fsl,imx28-pinctrl";
- reg = <0x80018000 2000>;
-
- mmc0_8bit_pins_a: mmc0-8bit@0 {
- reg = <0>;
- fsl,pinmux-ids = <
- MX28_PAD_SSP0_DATA0__SSP0_D0
- MX28_PAD_SSP0_DATA1__SSP0_D1
- MX28_PAD_SSP0_DATA2__SSP0_D2
- MX28_PAD_SSP0_DATA3__SSP0_D3
- MX28_PAD_SSP0_DATA4__SSP0_D4
- MX28_PAD_SSP0_DATA5__SSP0_D5
- MX28_PAD_SSP0_DATA6__SSP0_D6
- MX28_PAD_SSP0_DATA7__SSP0_D7
- MX28_PAD_SSP0_CMD__SSP0_CMD
- MX28_PAD_SSP0_DETECT__SSP0_CARD_DETECT
- MX28_PAD_SSP0_SCK__SSP0_SCK
- >;
- fsl,drive-strength = <MXS_DRIVE_4mA>;
- fsl,voltage = <MXS_VOLTAGE_HIGH>;
- fsl,pull-up = <MXS_PULL_ENABLE>;
- };
-
- mmc_cd_cfg: mmc-cd-cfg {
- fsl,pinmux-ids = <MX28_PAD_SSP0_DETECT__SSP0_CARD_DETECT>;
- fsl,pull-up = <MXS_PULL_DISABLE>;
- };
-
- mmc_sck_cfg: mmc-sck-cfg {
- fsl,pinmux-ids = <MX28_PAD_SSP0_SCK__SSP0_SCK>;
- fsl,drive-strength = <MXS_DRIVE_12mA>;
- fsl,pull-up = <MXS_PULL_DISABLE>;
- };
-};
-
-In this example, group node mmc0-8bit defines a group of pins for mxs SSP0
-to function as a 8-bit mmc device, with 8mA, 3.3V and pull-up configurations
-applied on all these pins. And config nodes mmc-cd-cfg and mmc-sck-cfg are
-adjusting the configuration for pins card-detection and clock from what group
-node mmc0-8bit defines. Only the configuration properties to be adjusted need
-to be listed in the config nodes.
-
-Valid values for i.MX28/i.MX23 pinmux-id are defined in
-arch/arm/boot/dts/imx28-pinfunc.h and arch/arm/boot/dts/imx23-pinfunc.h.
-The definitions for the padconfig properties can be found in
-arch/arm/boot/dts/mxs-pinfunc.h.

- - reg: address and size of registers controlling irq functionality
-
-=== GPIO sub-nodes ===
-
-The GPIO bank for the controller is represented as a sub-node and it acts as a
-GPIO controller.
-
-Required properties for sub-nodes are:
- - reg: should contain a list of address and size, one tuple for each entry
- in reg-names.
- - reg-names: an array of strings describing the "reg" entries.
- Must contain "mux" and "gpio".
- May contain "pull", "pull-enable" and "ds" when appropriate.
- - gpio-controller: identifies the node as a gpio controller
- - #gpio-cells: must be 2
-
-=== Other sub-nodes ===
-
-Child nodes without the "gpio-controller" represent some desired
-configuration for a pin or a group. Those nodes can be pinmux nodes or
-configuration nodes.
-
-Required properties for pinmux nodes are:
- - groups: a list of pinmux groups. The list of all available groups
- depends on the SoC and can be found in driver sources.
- - function: the name of a function to activate for the specified set
- of groups. The list of all available functions depends on the SoC
- and can be found in driver sources.
-
-Required properties for configuration nodes:
- - pins: a list of pin names
-
-Configuration nodes support the following generic properties, as
-described in file pinctrl-bindings.txt:
- - "bias-disable"
- - "bias-pull-up"
- - "bias-pull-down"
- - "output-enable"
- - "output-disable"
- - "output-low"
- - "output-high"
-
-Optional properties :
- - drive-strength-microamp: Drive strength for the specified pins in uA.
- This property is only valid for G12A and newer.

-NXP LPC18xx/43xx SCU pin controller Device Tree Bindings
---------------------------------------------------------
-
-Required properties:
-- compatible : Should be "nxp,lpc1850-scu"
-- reg : Address and length of the register set for the device
-- clocks : Clock specifier (see clock bindings for details)
-
-The lpc1850-scu driver uses the generic pin multiplexing and generic pin
-configuration documented in pinctrl-bindings.txt.
-
-The following generic nodes are supported:
- - function
- - pins
- - bias-disable
- - bias-pull-up
- - bias-pull-down
- - drive-strength
- - input-enable
- - input-disable
- - input-schmitt-enable
- - input-schmitt-disable
- - slew-rate
-
-NXP specific properties:
- - nxp,gpio-pin-interrupt : Assign pin to gpio pin interrupt controller
- irq number 0 to 7. See example below.
-
-Not all pins support all properties so either refer to the NXP 1850/4350
-user manual or the pin table in the pinctrl-lpc18xx driver for supported
-pin properties.
-
-Example:
-pinctrl: pinctrl@40086000 {
- compatible = "nxp,lpc1850-scu";
- reg = <0x40086000 0x1000>;
- clocks = <&ccu1 CLK_CPU_SCU>;

-Microchip MCP2308/MCP23S08/MCP23017/MCP23S17 driver for

-
-Required properties:
-- compatible : Should be
- - "mcp,mcp23s08" (DEPRECATED) for 8 GPIO SPI version
- - "mcp,mcp23s17" (DEPRECATED) for 16 GPIO SPI version
- - "mcp,mcp23008" (DEPRECATED) for 8 GPIO I2C version or
- - "mcp,mcp23017" (DEPRECATED) for 16 GPIO I2C version of the chip
-
- - "microchip,mcp23s08" for 8 GPIO SPI version
- - "microchip,mcp23s17" for 16 GPIO SPI version
- - "microchip,mcp23s18" for 16 GPIO SPI version
- - "microchip,mcp23008" for 8 GPIO I2C version or
- - "microchip,mcp23017" for 16 GPIO I2C version of the chip
- - "microchip,mcp23018" for 16 GPIO I2C version
- NOTE: Do not use the old mcp prefix any more. It is deprecated and will be
- removed.
-- #gpio-cells : Should be two.
- - first cell is the pin number
- - second cell is used to specify flags as described in
- 'Documentation/devicetree/bindings/gpio/gpio.txt'. Allowed values defined by
- 'include/dt-bindings/gpio/gpio.h' (e.g. GPIO_ACTIVE_LOW).
-- gpio-controller : Marks the device node as a GPIO controller.
-- reg : For an address on its bus. I2C uses this a the I2C address of the chip.
- SPI uses this to specify the chipselect line which the chip is
- connected to. The driver and the SPI variant of the chip support
- multiple chips on the same chipselect. Have a look at
- microchip,spi-present-mask below.
-
-Required device specific properties (only for SPI chips):
-- mcp,spi-present-mask (DEPRECATED)
-- microchip,spi-present-mask : This is a present flag, that makes only sense for SPI
- chips - as the name suggests. Multiple SPI chips can share the same
- SPI chipselect. Set a bit in bit0-7 in this mask to 1 if there is a
- chip connected with the corresponding spi address set. For example if
- you have a chip with address 3 connected, you have to set bit3 to 1,
- which is 0x08. mcp23s08 chip variant only supports bits 0-3. It is not
- possible to mix mcp23s08 and mcp23s17 on the same chipselect. Set at
- least one bit to 1 for SPI chips.
- NOTE: Do not use the old mcp prefix any more. It is deprecated and will be
- removed.
-- spi-max-frequency = The maximum frequency this chip is able to handle
-
-Optional properties:
-- #interrupt-cells : Should be two.
- - first cell is the pin number
- - second cell is used to specify flags.
-- interrupt-controller: Marks the device node as a interrupt controller.
-- drive-open-drain: Sets the ODR flag in the IOCON register. This configures
- the IRQ output as open drain active low.
-- reset-gpios: Corresponds to the active-low RESET# pin for the chip
-
-Optional device specific properties:
-- microchip,irq-mirror: Sets the mirror flag in the IOCON register. Devices
- with two interrupt outputs (these are the devices ending with 17 and
- those that have 16 IOs) have two IO banks: IO 0-7 form bank 1 and
- IO 8-15 are bank 2. These chips have two different interrupt outputs:
- One for bank 1 and another for bank 2. If irq-mirror is set, both
- interrupts are generated regardless of the bank that an input change
- occurred on. If it is not set, the interrupt are only generated for the
- bank they belong to.
- On devices with only one interrupt output this property is useless.
-- microchip,irq-active-high: Sets the INTPOL flag in the IOCON register. This
- configures the IRQ output polarity as active high.
-
-Example I2C (with interrupt):
-gpiom1: gpio@20 {
- compatible = "microchip,mcp23017";
- gpio-controller;
- #gpio-cells = <2>;
- reg = <0x20>;
-
- interrupt-parent = <&gpio1>;
- interrupts = <17 IRQ_TYPE_LEVEL_LOW>;
- interrupt-controller;
- #interrupt-cells=<2>;
- microchip,irq-mirror;
-};
-
-Example SPI:
-gpiom1: gpio@0 {
- compatible = "microchip,mcp23s17";
- gpio-controller;
- #gpio-cells = <2>;
- microchip,spi-present-mask = <0x01>;
- reg = <0>;
- spi-max-frequency = <1000000>;
-};
-
-Pull-up configuration
-=====================
-
-If pins are used as output, they can also be configured with pull-ups. This is
-done with pinctrl.
-
-Please refer file <devicetree/bindings/pinctrl/pinctrl-bindings.txt>
-for details of the common pinctrl bindings used by client devices,
-including the meaning of the phrase "pin configuration node".
-
-Optional Pinmux properties:
---------------------------
-Following properties are required if default setting of pins are required
-at boot.
-- pinctrl-names: A pinctrl state named per <pinctrl-bindings.txt>.
-- pinctrl[0...n]: Properties to contain the phandle for pinctrl states per
- <pinctrl-bindings.txt>.
-
-The pin configurations are defined as child of the pinctrl states node. Each
-sub-node have following properties:
-
-Required properties:
-------------------
-- pins: List of pins. Valid values of pins properties are:
- gpio0 ... gpio7 for the devices with 8 GPIO pins and
- gpio0 ... gpio15 for the devices with 16 GPIO pins.
-
-Optional properties:
--------------------
-The following optional property is defined in the pinmux DT binding document
-<pinctrl-bindings.txt>. Absence of this property will leave the configuration
-in its default state.
- bias-pull-up
-
-Example with pinctrl to pull-up output pins:
-gpio21: gpio@21 {
- compatible = "microchip,mcp23017";
- gpio-controller;
- #gpio-cells = <0x2>;
- reg = <0x21>;
- interrupt-parent = <&socgpio>;

- pinctrl-names = "default";
- pinctrl-0 = <&i2cgpio0irq>, <&gpio21pullups>;
- reset-gpios = <&gpio6 15 GPIO_ACTIVE_LOW>;
-
- gpio21pullups: pinmux {
- pins = "gpio0", "gpio1", "gpio2", "gpio3",
- "gpio4", "gpio5", "gpio6", "gpio7",
- "gpio8", "gpio9", "gpio10", "gpio11",

-- pinctrl-single,register-width : pinmux register access width in bits
-
-- pinctrl-single,function-mask : mask of allowed pinmux function bits
- in the pinmux register
-
-Optional properties:
-- pinctrl-single,function-off : function off mode for disabled state if
- available and same for all registers; if not specified, disabling of
- pin functions is ignored
-
-- pinctrl-single,bit-per-mux : boolean to indicate that one register controls
- more than one pin, for which "pinctrl-single,function-mask" property specifies
- position mask of pin.
-
-- pinctrl-single,drive-strength : array of value that are used to configure
- drive strength in the pinmux register. They're value of drive strength
- current and drive strength mask.
-
- /* drive strength current, mask */
- pinctrl-single,power-source = <0x30 0xf0>;

- /* input, enabled pulldown bits, disabled pulldown bits, mask */
- pinctrl-single,bias-pulldown = <2 2 0 2>;
-
- * Two bits to control input bias pullup and pulldown: User should use
- pinctrl-single,bias-pullup & pinctrl-single,bias-pulldown. One bit means
- pullup, and the other one bit means pulldown.
- * Three bits to control input bias enable, pullup and pulldown. User should
- use pinctrl-single,bias-pullup & pinctrl-single,bias-pulldown. Input bias
- enable bit should be included in pullup or pulldown bits.
- * Although driver could set PIN_CONFIG_BIAS_DISABLE, there's no property as
- pinctrl-single,bias-disable. Because pinctrl single driver could implement
- it by calling pulldown, pullup disabled.
-
-- pinctrl-single,input-schmitt : array of value that are used to configure

- pinctrl-single,low-power-mode = <0x288 0x388>;
-
-- pinctrl-single,gpio-range : list of value that are used to configure a GPIO
- range. They're value of subnode phandle, pin base in pinctrl device, pin
- number in this range, GPIO function value of this GPIO range.
- The number of parameters is depend on #pinctrl-single,gpio-range-cells

-- interrupt-controller : standard interrupt controller binding if using
- interrupts for wake-up events for example. In this case pinctrl-single
- is set up as a chained interrupt controller and the wake-up interrupts
- can be requested by the drivers using request_irq().
-
-- #interrupt-cells : standard interrupt binding if using interrupts
-
-This driver assumes that there is only one register for each pin (unless the
-pinctrl-single,bit-per-mux is set), and uses the common pinctrl bindings as
-specified in the pinctrl-bindings.txt document in this directory.
-
-The pin configuration nodes for pinctrl-single are specified as pinctrl
-register offset and values using pinctrl-single,pins. Only the bits specified
-in pinctrl-single,function-mask are updated.
-
-When #pinctrl-cells = 1, then setting a pin for a device could be done with:
-
- pinctrl-single,pins = <0xdc 0x118>;
-
-Where 0xdc is the offset from the pinctrl register base address for the device
-pinctrl register, and 0x118 contains the desired value of the pinctrl register.
-
-When #pinctrl-cells = 2, then setting a pin for a device could be done with:
-
- pinctrl-single,pins = <0xdc 0x30 0x07>;
-
-Where 0x30 is the pin configuration value and 0x07 is the pin mux mode value.
-These two values are OR'd together to produce the value stored at offset 0xdc.
-See the device example and static board pins example below for more information.
-
-In case when one register changes more than one pin's mux the
-pinctrl-single,bits need to be used which takes three parameters:
-
- pinctrl-single,bits = <0xdc 0x18 0xff>;
-
-Where 0xdc is the offset from the pinctrl register base address for the
-device pinctrl register, 0x18 is the desired value, and 0xff is the sub mask to
-be used when applying this change to the register.
-
-
-Optional sub-node: In case some pins could be configured as GPIO in the pinmux
-register, those pins could be defined as a GPIO range. This sub-node is required
-by pinctrl-single,gpio-range property.
-
-Required properties in sub-node:
-- #pinctrl-single,gpio-range-cells : the number of parameters after phandle in
- pinctrl-single,gpio-range property.

+ Some pin controller devices use a single register for one or more pins. The
+ range of pin control registers can vary from one to many for each controller
+ instance. Some SoCs from Altera, Broadcom, HiSilicon, Ralink, and TI have this

-Required properties:
-- compatible: "qcom,apq8064-pinctrl"
-- reg: Should be the base address and length of the TLMM block.
-- interrupts: Should be the parent IRQ of the TLMM block.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Should be two.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells : Should be two.
- The first cell is the gpio pin number and the
- second cell is used for optional parameters.
-- gpio-ranges: see ../gpio/gpio.txt
-
-Optional properties:
-
-- gpio-reserved-ranges: see ../gpio/gpio.txt
-
-Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
-a general description of GPIO and interrupt bindings.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-Qualcomm's pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those pin(s)/group(s), and various pin configuration
-parameters, such as pull-up, drive strength, etc.
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function.
-
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pin configuration subnode:
-
- pins, function, bias-disable, bias-pull-down, bias-pull-up, drive-strength,
- output-low, output-high.
-
-Non-empty subnodes must specify the 'pins' property.
-
-Valid values for pins are:
- gpio0-gpio89
-
-Valid values for function are:
- cam_mclk, codec_mic_i2s, codec_spkr_i2s, gp_clk_0a, gp_clk_0b, gp_clk_1a,
- gp_clk_1b, gp_clk_2a, gp_clk_2b, gpio, gsbi1, gsbi2, gsbi3, gsbi4,
- gsbi4_cam_i2c, gsbi5, gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6,
- gsbi6_spi_cs1, gsbi6_spi_cs2, gsbi6_spi_cs3, gsbi7, gsbi7_spi_cs1,
- gsbi7_spi_cs2, gsbi7_spi_cs3, gsbi_cam_i2c, hdmi, mi2s, riva_bt, riva_fm,
- riva_wlan, sdc2, sdc4, slimbus, spkr_i2s, tsif1, tsif2, usb2_hsic, ps_hold
-
-Example:
-
- msmgpio: pinctrl@800000 {
- compatible = "qcom,apq8064-pinctrl";

-Qualcomm Atheros IPQ4019 TLMM block
-
-This is the Top Level Mode Multiplexor block found on the Qualcomm IPQ8019
-platform, it provides pinctrl, pinmux, pinconf, and gpiolib facilities.
-
-Required properties:
-- compatible: "qcom,ipq4019-pinctrl"
-- reg: Should be the base address and length of the TLMM block.
-- interrupts: Should be the parent IRQ of the TLMM block.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Should be two.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells : Should be two.
- The first cell is the gpio pin number and the
- second cell is used for optional parameters.
-- gpio-ranges: see ../gpio/gpio.txt
-
-Optional properties:
-
-- gpio-reserved-ranges: see ../gpio/gpio.txt
-
-Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
-a general description of GPIO and interrupt bindings.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-The pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those pin(s)/group(s), and various pin configuration
-parameters, such as pull-up, drive strength, etc.
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function.
-
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pin configuration subnode:
- pins, function, bias-disable, bias-pull-down, bias-pull-up, drive-open-drain,
- drive-strength.
-
-Non-empty subnodes must specify the 'pins' property.
-Note that not all properties are valid for all pins.
-
-
-Valid values for qcom,pins are:
- gpio0-gpio99
- Supports mux, bias and drive-strength
-
-Valid values for qcom,function are:
-aud_pin, audio_pwm, blsp_i2c0, blsp_i2c1, blsp_spi0, blsp_spi1, blsp_uart0,
-blsp_uart1, chip_rst, gpio, i2s_rx, i2s_spdif_in, i2s_spdif_out, i2s_td, i2s_tx,
-jtag, led0, led1, led2, led3, led4, led5, led6, led7, led8, led9, led10, led11,
-mdc, mdio, pcie, pmu, prng_rosc, qpic, rgmii, rmii, sdio, smart0, smart1,
-smart2, smart3, tm, wifi0, wifi1
-
-Example:
-
- tlmm: pinctrl@1000000 {
- compatible = "qcom,ipq4019-pinctrl";
- reg = <0x1000000 0x300000>;

- #gpio-cells = <2>;
- gpio-ranges = <&tlmm 0 0 100>;
- interrupt-controller;
- #interrupt-cells = <2>;
- interrupts = <0 208 0>;
-
- serial_pins: serial_pinmux {
- mux {
- pins = "gpio60", "gpio61";
- function = "blsp_uart0";
- bias-disable;
- };
- };

-Qualcomm IPQ8064 TLMM block
-
-Required properties:
-- compatible: "qcom,ipq8064-pinctrl"
-- reg: Should be the base address and length of the TLMM block.
-- interrupts: Should be the parent IRQ of the TLMM block.
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells: Should be two.
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells : Should be two.
- The first cell is the gpio pin number and the
- second cell is used for optional parameters.
-- gpio-ranges: see ../gpio/gpio.txt
-
-Optional properties:
-
-- gpio-reserved-ranges: see ../gpio/gpio.txt
-
-Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
-a general description of GPIO and interrupt bindings.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-Qualcomm's pin configuration nodes act as a container for an arbitrary number of
-subnodes. Each of these subnodes represents some desired configuration for a
-pin, a group, or a list of pins or groups. This configuration can include the
-mux function to select on those pin(s)/group(s), and various pin configuration
-parameters, such as pull-up, drive strength, etc.
-
-The name of each subnode is not important; all subnodes should be enumerated
-and processed purely based on their content.
-
-Each subnode only affects those parameters that are explicitly listed. In
-other words, a subnode that lists a mux function but no pin configuration
-parameters implies no information about any pin configuration parameters.
-Similarly, a pin subnode that describes a pullup parameter implies no
-information about e.g. the mux function.
-
-
-The following generic properties as defined in pinctrl-bindings.txt are valid
-to specify in a pin configuration subnode:
-
- pins, function, bias-disable, bias-pull-down, bias-pull-up, drive-strength,
- output-low, output-high.
-
-Non-empty subnodes must specify the 'pins' property.
-
-Valid values for qcom,pins are:
- gpio0-gpio68
- Supports mux, bias, and drive-strength
-
- sdc3_clk, sdc3_cmd, sdc3_data
- Supports bias and drive-strength
-
-
-Valid values for function are:
- mdio, mi2s, pdm, ssbi, spmi, audio_pcm, gpio, gsbi1, gsbi2, gsbi4, gsbi5,
- gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6, gsbi7, nss_spi, sdc1,
- spdif, nand, tsif1, tsif2, usb_fs_n, usb_fs, usb2_hsic, rgmii2, sata,
- pcie1_rst, pcie1_prsnt, pcie1_pwren_n, pcie1_pwren, pcie1_pwrflt,
- pcie1_clk_req, pcie2_rst, pcie2_prsnt, pcie2_pwren_n, pcie2_pwren,
- pcie2_pwrflt, pcie2_clk_req, pcie3_rst, pcie3_prsnt, pcie3_pwren_n,
- pcie3_pwren, pcie3_pwrflt, pcie3_clk_req, ps_hold
-
-Example:
-
- pinmux: pinctrl@800000 {

+description:
+ The Renesas RZ/T2H and RZ/N2H SoCs feature a combined Pin and GPIO controller.
+ Pin multiplexing and GPIO configuration are performed on a per-pin basis.
+ Each port supports up to 8 pins, each configurable for either GPIO (port mode)
+ or alternate function mode. Each pin supports function mode values ranging from
+ 0x0 to 0x2A, allowing selection from up to 43 different functions.

-* Spreadtrum Pin Controller
-
-The Spreadtrum pin controller are organized in 3 blocks (types).
-
-The first block comprises some global control registers, and each
-register contains several bit fields with one bit or several bits
-to configure for some global common configuration, such as domain
-pad driving level, system control select and so on ("domain pad
-driving level": One pin can output 3.0v or 1.8v, depending on the
-related domain pad driving selection, if the related domain pad
-slect 3.0v, then the pin can output 3.0v. "system control" is used
-to choose one function (like: UART0) for which system, since we
-have several systems (AP/CP/CM4) on one SoC.).
-
-There are too much various configuration that we can not list all
-of them, so we can not make every Spreadtrum-special configuration
-as one generic configuration, and maybe it will add more strange
-global configuration in future. Then we add one "sprd,control" to
-set these various global control configuration, and we need use
-magic number for this property.
-
-Moreover we recognise every fields comprising one bit or several
-bits in one global control register as one pin, thus we should
-record every pin's bit offset, bit width and register offset to
-configure this field (pin).
-
-The second block comprises some common registers which have unified
-register definition, and each register described one pin is used
-to configure the pin sleep mode, function select and sleep related
-configuration.
-
-Now we have 4 systems for sleep mode on SC9860 SoC: AP system,
-PUBCP system, TGLDSP system and AGDSP system. And the pin sleep
-related configuration are:
-- input-enable
-- input-disable
-- output-high
-- output-low
-- bias-pull-up
-- bias-pull-down
-
-In some situation we need set the pin sleep mode and pin sleep related
-configuration, to set the pin sleep related configuration automatically
-by hardware when the system specified by sleep mode goes into deep
-sleep mode. For example, if we set the pin sleep mode as PUBCP_SLEEP
-and set the pin sleep related configuration as "input-enable", which
-means when PUBCP system goes into deep sleep mode, this pin will be set
-input enable automatically.
-
-Moreover we can not use the "sleep" state, since some systems (like:
-PUBCP system) do not run linux kernel OS (only AP system run linux
-kernel on SC9860 platform), then we can not select "sleep" state
-when the PUBCP system goes into deep sleep mode. Thus we introduce
-"sprd,sleep-mode" property to set pin sleep mode.
-
-The last block comprises some misc registers which also have unified
-register definition, and each register described one pin is used to
-configure drive strength, pull up/down and so on. Especially for pull
-up, we have two kind pull up resistor: 20K and 4.7K.
-
-Required properties for Spreadtrum pin controller:
-- compatible: "sprd,<soc>-pinctrl"
- Please refer to each sprd,<soc>-pinctrl.txt binding doc for supported SoCs.
-- reg: The register address of pin controller device.
-- pins : An array of pin names.
-

+title: Spreadtrum SC9860 Pin Controller
+
+maintainers:
+ - Baolin Wang <baolin.wang@linux.alibaba.com>
+
+description: >
+ The Spreadtrum pin controller are organized in 3 blocks (types).
+
+ The first block comprises some global control registers, and each
+ register contains several bit fields with one bit or several bits
+ to configure for some global common configuration, such as domain
+ pad driving level, system control select and so on ("domain pad
+ driving level": One pin can output 3.0v or 1.8v, depending on the
+ related domain pad driving selection, if the related domain pad
+ select 3.0v, then the pin can output 3.0v. "system control" is used
+ to choose one function (like: UART0) for which system, since we
+ have several systems (AP/CP/CM4) on one SoC.).
+
+ There are too much various configuration that we can not list all
+ of them, so we can not make every Spreadtrum-special configuration
+ as one generic configuration, and maybe it will add more strange
+ global configuration in future. Then we add one "sprd,control" to
+ set these various global control configuration, and we need use
+ magic number for this property.
+
+ Moreover we recognize every fields comprising one bit or several
+ bits in one global control register as one pin, thus we should
+ record every pin's bit offset, bit width and register offset to
+ configure this field (pin).
+
+ The second block comprises some common registers which have unified
+ register definition, and each register described one pin is used
+ to configure the pin sleep mode, function select and sleep related
+ configuration.
+
+ Now we have 4 systems for sleep mode on SC9860 SoC: AP system,
+ PUBCP system, TGLDSP system and AGDSP system. And the pin sleep
+ related configuration are:
+ - input-enable
+ - input-disable
+ - output-high
+ - output-low
+ - bias-pull-up
+ - bias-pull-down
+
+ In some situation we need set the pin sleep mode and pin sleep related
+ configuration, to set the pin sleep related configuration automatically
+ by hardware when the system specified by sleep mode goes into deep
+ sleep mode. For example, if we set the pin sleep mode as PUBCP_SLEEP
+ and set the pin sleep related configuration as "input-enable", which
+ means when PUBCP system goes into deep sleep mode, this pin will be set
+ input enable automatically.
+
+ Moreover we can not use the "sleep" state, since some systems (like:
+ PUBCP system) do not run linux kernel OS (only AP system run linux
+ kernel on SC9860 platform), then we can not select "sleep" state
+ when the PUBCP system goes into deep sleep mode. Thus we introduce
+ "sprd,sleep-mode" property to set pin sleep mode.
+
+ The last block comprises some misc registers which also have unified
+ register definition, and each register described one pin is used to
+ configure drive strength, pull up/down and so on. Especially for pull
+ up, we have two kind pull up resistor: 20K and 4.7K.

+description: |
+ Pinmux and pinconf controller in the T-Head TH1520 RISC-V SoC.
+
+ The TH1520 has 3 groups of pads each controlled from different memory ranges.
+ Confusingly the memory ranges are named
+ PADCTRL_AOSYS -> PAD Group 1
+ PADCTRL1_APSYS -> PAD Group 2
+ PADCTRL0_APSYS -> PAD Group 3
+
+ Each pad can be muxed individually to up to 6 different functions. For most
+ pads only a few of those 6 configurations are valid though, and a few pads in
+ group 1 does not support muxing at all.
+
+ Pinconf is fairly regular except for a few pads in group 1 that either can't
+ be configured or has some special functions. The rest have configurable drive
+ strength, input enable, schmitt trigger, slew rate, pull-up and pull-down in
+ addition to a special strong pull up.
+
+ Certain pads in group 1 can be muxed to AUDIO_PA0 - AUDIO_PA30 functions and
+ are then meant to be used by the audio co-processor. Each such pad can then
+ be further muxed to either audio GPIO or one of 4 functions such as UART, I2C
+ and I2S. If the audio pad is muxed to one of the 4 functions then pinconf is
+ also configured in different registers. All of this is done from a different
+ AUDIO_IOCTRL memory range and is left to the audio co-processor for now.

+ pin, a group, or a list of pins or groups. This configuration can include the
+ mux function to select on those pin(s)/group(s), and various pin configuration

+ The name of each subnode is not important; all subnodes should be enumerated
+ and processed purely based on their content.

+description: |
+ Please refer to pinctrl-bindings.txt in this directory for details of the
+ common pinctrl bindings used by client devices, including the meaning of the
+ phrase "pin configuration node".
+
+ Versal's pin configuration nodes act as a container for an arbitrary number of
+ subnodes. Each of these subnodes represents some desired configuration for a
+ pin, a group, or a list of pins or groups. This configuration can include the
+ mux function to select on those pin(s)/group(s), and various pin configuration
+ parameters, such as pull-up, slew rate, etc.
+
+ Each configuration node can consist of multiple nodes describing the pinmux and
+ pinconf options. Those nodes can be pinmux nodes or pinconf nodes.

-description: |
- Please refer to pinctrl-bindings.txt in this directory for details of the
- common pinctrl bindings used by client devices, including the meaning of the
- phrase "pin configuration node".
-
- Zynq's pin configuration nodes act as a container for an arbitrary number of
- subnodes. Each of these subnodes represents some desired configuration for a
- pin, a group, or a list of pins or groups. This configuration can include the
- mux function to select on those pin(s)/group(s), and various pin configuration
- parameters, such as pull-up, slew rate, etc.
-
- Each configuration node can consist of multiple nodes describing the pinmux and
- pinconf options. Those nodes can be pinmux nodes or pinconf nodes.
-
- The name of each subnode is not important; all subnodes should be enumerated
- and processed purely based on their content.

-Device-tree bindings for persistent memory regions
------------------------------------------------------
-
-Persistent memory refers to a class of memory devices that are:
-
- a) Usable as main system memory (i.e. cacheable), and
- b) Retain their contents across power failure.
-
-Given b) it is best to think of persistent memory as a kind of memory mapped
-storage device. To ensure data integrity the operating system needs to manage
-persistent regions separately to the normal memory pool. To aid with that this
-binding provides a standardised interface for discovering where persistent
-memory regions exist inside the physical address space.
-
-Bindings for the region nodes:
------------------------------
-
-Required properties:
- - compatible = "pmem-region"
-
- - reg = <base, size>;
- The reg property should specificy an address range that is
- translatable to a system physical address range. This address
- range should be mappable as normal system memory would be
- (i.e cacheable).
-
- If the reg property contains multiple address ranges
- each address range will be treated as though it was specified
- in a separate device node. Having multiple address ranges in a
- node implies no special relationship between the two ranges.
-
-Optional properties:
- - Any relevant NUMA assocativity properties for the target platform.
-
- - volatile; This property indicates that this region is actually
- backed by non-persistent memory. This lets the OS know that it
- may skip the cache flushes required to ensure data is made
- persistent after a write.
-
- If this property is absent then the OS must assume that the region
- is backed by non-volatile memory.
-
-Examples:
---------------------
-
- /*
- * This node specifies one 4KB region spanning from
- * 0x5000 to 0x5fff that is backed by non-volatile memory.
- */
- pmem@5000 {
- compatible = "pmem-region";
- reg = <0x00005000 0x00001000>;
- };
-
- /*
- * This node specifies two 4KB regions that are backed by
- * volatile (normal) memory.
- */
- pmem@6000 {
- compatible = "pmem-region";
- reg = < 0x00006000 0x00001000
- 0x00008000 0x00001000 >;
- volatile;
- };

+title: Persistent Memory Regions
+
+description: |
+ Persistent memory refers to a class of memory devices that are:
+
+ a) Usable as main system memory (i.e. cacheable), and
+ b) Retain their contents across power failure.
+
+ Given b) it is best to think of persistent memory as a kind of memory mapped
+ storage device. To ensure data integrity the operating system needs to manage
+ persistent regions separately to the normal memory pool. To aid with that this
+ binding provides a standardised interface for discovering where persistent
+ memory regions exist inside the physical address space.

+description: |
+ The Toradex Embedded Controller (EC) is used on Toradex SMARC modules,
+ primarily to manage power and reset functionalities.
+
+ The EC provides the following functions:
+ - Reads the SMARC POWER_BTN# and RESET_IN# signals and controls the PMIC accordingly.
+ - Controls the SoC boot mode signals based on the SMARC BOOT_SEL# and FORCE_RECOV# inputs.
+ - Manages the CARRIER_STDBY# signal in response to relevant SoC signals.
+
+ The EC runs a small firmware, factory programmed into its internal flash, and communicates over I2C.
+ It allows software to control power-off and reset functionalities of the module.

+description: |
+ The RT9756/RT9757 is a high efficiency and high charge current charger.
+
+ The efficiency is up to 98.2% when VBAT = 4V, IBAT = 2A in DIV2 mode and 99.1%
+ when VBAT=4V, IBAT=1A in bypass mode. The maximum charger current is up to 8A
+ in DIV2 mode and 5A in bypass mode. The device integrates smart cap divider
+ topology, direct charging mode, external over-voltage protection control, an
+ input reverse blocking NFET and 2-way regulation, a dual phase charge pump
+ core, 8-Channel high speed ADCs and USB BC 1.2 detection.
+
+ RT9770 is almost the same with RT9756/57, only BC 1.2 detection function is
+ removed to shrink the die size.

+ The STC3117 includes the STMicroelectronics OptimGauge algorithm.
+ It provides accurate battery state-of-charge (SOC) monitoring, tracks
+ battery parameter changes with operation conditions, temperature,
+ and aging, and allows the application to get a battery state-of-health
+ (SOH) indication.
+
+ An alarm output signals low SOC or low voltage conditions and also
+ indicates fault conditions like a missing or swapped battery.

-thermistor-on-batctrl:
- A boolean value indicating thermistor interface to battery
-
- Note:
- 'btemp' and 'batctrl' are the pins interfaced for battery temperature

- 'batctrl' pin is used when NTC resister is internal to battery.
-
- Example:
- ab8500_battery: ab8500_battery {

- indicates: NTC resister is internal to battery, 'batctrl' is used
- for thermal measurement.
-
- The absence of property 'thermal-on-batctrl' indicates
- NTC resister is external to battery and 'btemp' signal is used

-
-Required properties:
-
-- compatible : must include "fsl,elo-dma"
-- reg : DMA General Status Register, i.e. DGSR which contains
- status for all the 4 DMA channels
-- ranges : describes the mapping between the address space of the
- DMA channels and the address space of the DMA controller
-- cell-index : controller index. 0 for controller @ 0x8100
-- interrupts : interrupt specifier for DMA IRQ
-
-- DMA channel nodes:
- - compatible : must include "fsl,elo-dma-channel"
- However, see note below.
- - reg : DMA channel specific registers
- - cell-index : DMA channel index starts at 0.
-
-Optional properties:
- - interrupts : interrupt specifier for DMA channel IRQ
- (on 83xx this is expected to be identical to
- the interrupts property of the parent node)

-Note on DMA channel compatible properties: The compatible property must say
-"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel" to be used by the Elo DMA
-driver (fsldma). Any DMA channel used by fsldma cannot be used by another
-DMA driver, such as the SSI sound drivers for the MPC8610. Therefore, any DMA
-channel that should be used for another driver should not use
-"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel". For the SSI drivers, for
-example, the compatible property should be "fsl,ssi-dma-channel". See ssi.txt
-for more information.

-=====================================================================
-Freescale MPIC Interrupt Controller Node
-Copyright (C) 2010,2011 Freescale Semiconductor Inc.
-=====================================================================
-
-The Freescale MPIC interrupt controller is found on all PowerQUICC
-and QorIQ processors and is compatible with the Open PIC. The
-notable difference from Open PIC binding is the addition of 2
-additional cells in the interrupt specifier defining interrupt type
-information.
-
-PROPERTIES
-
- - compatible
- Usage: required
- Value type: <string>
- Definition: Shall include "fsl,mpic". Freescale MPIC
- controllers compatible with this binding have Block
- Revision Registers BRR1 and BRR2 at offset 0x0 and
- 0x10 in the MPIC.
-
- - reg
- Usage: required
- Value type: <prop-encoded-array>
- Definition: A standard property. Specifies the physical
- offset and length of the device's registers within the
- CCSR address space.
-
- - interrupt-controller
- Usage: required
- Value type: <empty>
- Definition: Specifies that this node is an interrupt
- controller
-
- - #interrupt-cells
- Usage: required
- Value type: <u32>
- Definition: Shall be 2 or 4. A value of 2 means that interrupt
- specifiers do not contain the interrupt-type or type-specific
- information cells.
-
- - #address-cells
- Usage: required
- Value type: <u32>
- Definition: Shall be 0.
-
- - pic-no-reset
- Usage: optional
- Value type: <empty>
- Definition: The presence of this property specifies that the
- MPIC must not be reset by the client program, and that
- the boot program has initialized all interrupt source
- configuration registers to a sane state-- masked or
- directed at other cores. This ensures that the client
- program will not receive interrupts for sources not belonging
- to the client. The presence of this property also mandates
- that any initialization related to interrupt sources shall
- be limited to sources explicitly referenced in the device tree.
-
- - big-endian
- Usage: optional
- Value type: <empty>
- If present the MPIC will be assumed to be big-endian. Some
- device-trees omit this property on MPIC nodes even when the MPIC is
- in fact big-endian, so certain boards override this property.
-
- - single-cpu-affinity
- Usage: optional
- Value type: <empty>
- If present the MPIC will be assumed to only be able to route
- non-IPI interrupts to a single CPU at a time (EG: Freescale MPIC).
-
- - last-interrupt-source
- Usage: optional
- Value type: <u32>
- Some MPICs do not correctly report the number of hardware sources
- in the global feature registers. If specified, this field will
- override the value read from MPIC_GREG_FEATURE_LAST_SRC.
-
-INTERRUPT SPECIFIER DEFINITION
-
- Interrupt specifiers consists of 4 cells encoded as
- follows:
-
- <1st-cell> interrupt-number
-
- Identifies the interrupt source. The meaning
- depends on the type of interrupt.
-
- Note: If the interrupt-type cell is undefined
- (i.e. #interrupt-cells = 2), this cell
- should be interpreted the same as for
- interrupt-type 0-- i.e. an external or
- normal SoC device interrupt.
-
- <2nd-cell> level-sense information, encoded as follows:
- 0 = low-to-high edge triggered
- 1 = active low level-sensitive
- 2 = active high level-sensitive
- 3 = high-to-low edge triggered
-
- <3rd-cell> interrupt-type
-
- The following types are supported:
-
- 0 = external or normal SoC device interrupt
-
- The interrupt-number cell contains
- the SoC device interrupt number. The
- type-specific cell is undefined. The
- interrupt-number is derived from the
- MPIC a block of registers referred to as
- the "Interrupt Source Configuration Registers".
- Each source has 32-bytes of registers
- (vector/priority and destination) in this
- region. So interrupt 0 is at offset 0x0,
- interrupt 1 is at offset 0x20, and so on.
-
- 1 = error interrupt
-
- The interrupt-number cell contains
- the SoC device interrupt number for
- the error interrupt. The type-specific
- cell identifies the specific error
- interrupt number.
-
- 2 = MPIC inter-processor interrupt (IPI)
-
- The interrupt-number cell identifies
- the MPIC IPI number. The type-specific
- cell is undefined.
-
- 3 = MPIC timer interrupt
-
- The interrupt-number cell identifies
- the MPIC timer number. The type-specific
- cell is undefined.
-
- <4th-cell> type-specific information
-
- The type-specific cell is encoded as follows:
-
- - For interrupt-type 1 (error interrupt),
- the type-specific cell contains the
- bit number of the error interrupt in the
- Error Interrupt Summary Register.
-

-* Freescale MSI interrupt controller
-
-Required properties:
-- compatible : compatible list, may contain one or two entries
- The first is "fsl,CHIP-msi", where CHIP is the processor(mpc8610, mpc8572,
- etc.) and the second is "fsl,mpic-msi" or "fsl,ipic-msi" or
- "fsl,mpic-msi-v4.3" depending on the parent type and version. If mpic
- version is 4.3, the number of MSI registers is increased to 16, MSIIR1 is
- provided to access these 16 registers, and compatible "fsl,mpic-msi-v4.3"
- should be used. The first entry is optional; the second entry is
- required.
-
-- reg : It may contain one or two regions. The first region should contain
- the address and the length of the shared message interrupt register set.
- The second region should contain the address of aliased MSIIR or MSIIR1
- register for platforms that have such an alias, if using MSIIR1, the second
- region must be added because different MSI group has different MSIIR1 offset.
-
-- interrupts : each one of the interrupts here is one entry per 32 MSIs,
- and routed to the host interrupt controller. the interrupts should
- be set as edge sensitive. If msi-available-ranges is present, only
- the interrupts that correspond to available ranges shall be present.
-
-Optional properties:
-- msi-available-ranges: use <start count> style section to define which
- msi interrupt can be used in the 256 msi interrupts. This property is
- optional, without this, all the MSI interrupts can be used.
- Each available range must begin and end on a multiple of 32 (i.e.
- no splitting an individual MSI register or the associated PIC interrupt).
- MPIC v4.3 does not support this property because the 32 interrupts of an
- individual register are not continuous when using MSIIR1.
-
-- msi-address-64: 64-bit PCI address of the MSIIR register. The MSIIR register
- is used for MSI messaging. The address of MSIIR in PCI address space is
- the MSI message address.
-
- This property may be used in virtualized environments where the hypervisor
- has created an alternate mapping for the MSIR block. See below for an
- explanation.
-

-The Freescale hypervisor and msi-address-64
--------------------------------------------
-Normally, PCI devices have access to all of CCSR via an ATMU mapping. The
-Freescale MSI driver calculates the address of MSIIR (in the MSI register
-block) and sets that address as the MSI message address.
-
-In a virtualized environment, the hypervisor may need to create an IOMMU
-mapping for MSIIR. The Freescale ePAPR hypervisor has this requirement
-because of hardware limitations of the Peripheral Access Management Unit
-(PAMU), which is currently the only IOMMU that the hypervisor supports.
-The ATMU is programmed with the guest physical address, and the PAMU
-intercepts transactions and reroutes them to the true physical address.
-
-In the PAMU, each PCI controller is given only one primary window. The
-PAMU restricts DMA operations so that they can only occur within a window.
-Because PCI devices must be able to DMA to memory, the primary window must
-be used to cover all of the guest's memory space.
-
-PAMU primary windows can be divided into 256 subwindows, and each
-subwindow can have its own address mapping ("guest physical" to "true
-physical"). However, each subwindow has to have the same alignment, which
-means they cannot be located at just any address. Because of these
-restrictions, it is usually impossible to create a 4KB subwindow that
-covers MSIIR where it's normally located.
-
-Therefore, the hypervisor has to create a subwindow inside the same
-primary window used for memory, but mapped to the MSIR block (where MSIIR
-lives). The first subwindow after the end of guest memory is used for
-this. The address specified in the msi-address-64 property is the PCI
-address of MSIIR. The hypervisor configures the PAMU to map that address to
-the true physical address of MSIIR.

+ panels have different backlight specifications in terms of minimum/maximum
+ values for PWM frequency. If the LCDC PWM frequency range does not match the
+ LCD display panel, it is possible to use the standalone PWM Controller to
+ drive the backlight.

-Freescale FlexTimer Module (FTM) PWM controller
-
-The same FTM PWM device can have a different endianness on different SoCs. The
-device tree provides a property to describing this so that an operating system
-device driver can handle all variants of the device. Refer to the table below
-for the endianness of the FTM PWM block as integrated into the existing SoCs:
-
- SoC | FTM-PWM endianness
- --------+-------------------
- Vybrid | LE
- LS1 | BE
- LS2 | LE
-
-Please see ../regmap/regmap.txt for more detail about how to specify endian
-modes in device tree.

- compatible strings:
- - "fsl,vf610-ftm-pwm" for PWM compatible with the one integrated on VF610
- - "fsl,imx8qm-ftm-pwm" for PWM compatible with the one integrated on i.MX8QM
-- reg: Physical base address and length of the controller's registers
-- #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of
- the cells format.
-- clock-names: Should include the following module clock source entries:
- "ftm_sys" (module clock, also can be used as counter clock),
- "ftm_ext" (external counter clock),
- "ftm_fix" (fixed counter clock),
- "ftm_cnt_clk_en" (external and fixed counter clock enable/disable).
-- clocks: Must contain a phandle and clock specifier for each entry in
- clock-names, please see clock/clock-bindings.txt for details of the property
- values.
-- pinctrl-names: Must contain a "default" entry.
-- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
- See pinctrl/pinctrl-bindings.txt for details of the property values.
-- big-endian: Boolean property, required if the FTM PWM registers use a big-

+description: |
+ RZ/G2L General PWM Timer (GPT) composed of 8 channels with 32-bit timer
+ (GPT32E). It supports the following functions
+ * 32 bits x 8 channels.
+ * Up-counting or down-counting (saw waves) or up/down-counting
+ (triangle waves) for each counter.
+ * Clock sources independently selectable for each channel.
+ * Two I/O pins per channel.
+ * Two output compare/input capture registers per channel.
+ * For the two output compare/input capture registers of each channel,
+ four registers are provided as buffer registers and are capable of
+ operating as comparison registers when buffering is not in use.
+ * In output compare operation, buffer switching can be at crests or
+ troughs, enabling the generation of laterally asymmetric PWM waveforms.
+ * Registers for setting up frame cycles in each channel (with capability
+ for generating interrupts at overflow or underflow)
+ * Generation of dead times in PWM operation.
+ * Synchronous starting, stopping and clearing counters for arbitrary
+ channels.
+ * Starting, stopping, clearing and up/down counters in response to input
+ level comparison.
+ * Starting, clearing, stopping and up/down counters in response to a
+ maximum of four external triggers.
+ * Output pin disable function by dead time error and detected
+ short-circuits between output pins.
+ * A/D converter start triggers can be generated (GPT32E0 to GPT32E3)
+ * Enables the noise filter for input capture and external trigger
+ operation.
+
+ The below pwm channels are supported.

-MCP16502 PMIC
-
-Required properties:
-- compatible: "microchip,mcp16502"
-- reg: I2C slave address
-- lpm-gpios: GPIO for LPM pin. Note that this GPIO *must* remain high during
- suspend-to-ram, keeping the PMIC into HIBERNATE mode; this
- property is optional;
-- regulators: A node that houses a sub-node for each regulator within
- the device. Each sub-node is identified using the node's
- name. The content of each sub-node is defined by the
- standard binding for regulators; see regulator.txt.
-
-Regulators of MCP16502 PMIC:
-1) VDD_IO - Buck (1.2 - 3.7 V)
-2) VDD_DDR - Buck (0.6 - 1.85 V)
-3) VDD_CORE - Buck (0.6 - 1.85 V)
-4) VDD_OTHER - BUCK (0.6 - 1.85 V)
-5) LDO1 - LDO (1.2 - 3.7 V)
-6) LDO2 - LDO (1.2 - 3.7 V)
-
-Regulator modes:
-2 - FPWM: higher precision, higher consumption
-4 - AutoPFM: lower precision, lower consumption
-
-Each regulator is defined using the standard binding for regulators.

-All voltage regulators provided by the MT6358 PMIC are described as the
-subnodes of the MT6358 regulators node. Each regulator is named according
-to its regulator type, buck_<name> and ldo_<name>. The definition for each
-of these nodes is defined using the standard binding for regulators at
-Documentation/devicetree/bindings/regulator/regulator.txt.
-
-The valid names for regulators are::
-BUCK:

+description: |
+ The RAA215300 is a high-performance, low-cost 9-channel PMIC designed for
+ 32-bit and 64-bit MCU and MPU applications. It supports DDR3, DDR3L, DDR4,
+ and LPDDR4 memory power requirements. The internally compensated regulators,
+ built-in Real-Time Clock (RTC), 32kHz crystal oscillator, and coin cell
+ battery charger provide a highly integrated, small footprint power solution
+ ideal for System-On-Module (SOM) applications. A spread spectrum feature
+ provides an ease-of-use solution for noise-sensitive audio or RF applications.
+
+ This device exposes two devices via I2C. One for the integrated RTC IP, and

+ operation modes for all buck rails, automatic power saving mode (Auto mode) and forced continuous
+ conduction mode (FCCM).
+
+ The definition of modes is in the datasheet which is available in below link
+ and their meaning is::
+ 0 - Auto mode for power saving, which reducing the switching frequency at light load condition
+ to maintain high frequency.
+ 1 - FCCM to meet the strict voltage regulation accuracy, which keeping constant switching frequency.
+
+ Datasheet will be available soon at
+ https://www.richtek.com/assets/Products

-
-Optional properties:
-- interrupt-parent : Specifies the reference to the interrupt controller.
-- interrupts : IRQ line information.
-- dlg,cs-gpios : Specify a valid GPIO for chip select
-
-Sub-nodes:

-Optional Subnode:
-Device supports two regulators OUTP and OUTN. A sub node within the
- device node describe the properties of these regulators. The sub-node
- names must be as follows:
- -For regulator outp, the sub node name should be "outp".
- -For regulator outn, the sub node name should be "outn".

--enable-gpios:(active high, output) Regulators are controlled by the input pins.
- If it is connected to GPIO through host system then provide the
- gpio number as per gpio.txt.
--active-discharge-gpios: (active high, output) Some configurations use delay mechanisms
- on the enable pin, to keep the regulator enabled for some time after
- the enable signal goes low. This GPIO is used to actively discharge
- the delay mechanism. Requires specification of ti,active-discharge-time-us
--ti,active-discharge-time-us: how long the active discharge gpio should be
- asserted for during active discharge, in microseconds.

-Bindings for Voltage controlled regulators
-==========================================
-
-Required properties:
---------------------
-- compatible : must be "vctrl-regulator".
-- regulator-min-microvolt : smallest voltage consumers may set
-- regulator-max-microvolt : largest voltage consumers may set
-- ctrl-supply : The regulator supplying the control voltage.
-- ctrl-voltage-range : an array of two integer values describing the range
- (min/max) of the control voltage. The values specify
- the control voltage needed to generate the corresponding
- regulator-min/max-microvolt output voltage.
-
-Optional properties:
---------------------
-- ovp-threshold-percent : overvoltage protection (OVP) threshold of the
- regulator in percent. Some regulators have an OVP
- circuitry which shuts down the regulator when the
- actual output voltage deviates beyond a certain
- margin from the expected value for a given control
- voltage. On larger voltage decreases this can occur
- undesiredly since the output voltage does not adjust
- inmediately to changes in the control voltage. To
- avoid this situation the vctrl driver breaks down
- larger voltage decreases into multiple steps, where
- each step is within the OVP threshold.
-- min-slew-down-rate : Describes how slowly the regulator voltage will decay
- down in the worst case (lightest expected load).
- Specified in uV / us (like main regulator ramp rate).
- This value is required when ovp-threshold-percent is
- specified.
-
-Example:
-
- vctrl-reg {
- compatible = "vctrl-regulator";
- regulator-name = "vctrl_reg";
-
- ctrl-supply = <&ctrl_reg>;
-
- regulator-min-microvolt = <800000>;
- regulator-max-microvolt = <1500000>;
-
- ctrl-voltage-range = <200000 500000>;
-
- min-slew-down-rate = <225>;
- ovp-threshold-percent = <16>;
- };

+ The firmware running on the processor inside the RPM subsystem allows each
+ component in the system to vote for state of the system resources, such as
+ clocks, regulators and bus frequencies. It implements multiple separate
+ communication interfaces that are described in subnodes, e.g. SMD and MPM:
+
+ +------------------------------+

+ | MPM Hardware |

+
+ The services provided by the firmware are only available after the firmware
+ has been loaded and the processor has been released from reset. Usually this
+ happens early in the boot process before the operating system is started.

-description: >
- Reserved memory is specified as a node under the /reserved-memory node. The
- operating system shall exclude reserved memory from normal usage one can
- create child nodes describing particular reserved (excluded from normal use)
- memory regions. Such memory regions are usually designed for the special
- usage by various device drivers.
-
- Each child of the reserved-memory node specifies one or more regions
- of reserved memory. Each child node may either use a 'reg' property to
- specify a specific range of reserved memory, or a 'size' property with
- optional constraints to request a dynamically allocated block of
- memory.
-
- Following the generic-names recommended practice, node names should
- reflect the purpose of the node (ie. "framebuffer" or "dma-pool").
- Unit address (@<address>) should be appended to the name if the node
- is a static allocation.

-
- The specifier consists of an address/size pair and denotes the IO
- virtual address range of the region for the given device. The exact
- format depends on the values of the "#address-cells" and "#size-cells"
- properties of the device referenced via the phandle.
-
- When used in combination with a "reg" property, an IOVA mapping is to
- be established for this memory region. One example where this can be
- useful is to create an identity mapping for physical memory that the
- firmware has configured some hardware to access (such as a bootsplash
- framebuffer).
-
- If no "reg" property is specified, the "iommu-addresses" property

+description: |
+ The Zynq UltraScale+ MPSoC and Versal has several different resets.
+
+ The PS reset subsystem is responsible for handling the external reset
+ input to the device and that all internal reset requirements are met
+ for the system (as a whole) and for the functional units.
+
+ Please also refer to reset.txt in this directory for common reset
+ controller binding usage. Device nodes that need access to reset
+ lines should specify them as a reset phandle in their corresponding
+ node as specified in reset.txt.

+description: |
+ RISC-V has a large number of extensions, some of which are "standard"
+ extensions, meaning they are ratified by RISC-V International, and others
+ are "vendor" extensions.
+ This document defines properties that indicate whether a hart supports a
+ given extension.
+
+ Once a standard extension has been ratified, no changes in behaviour can be
+ made without the creation of a new extension.
+ The properties for standard extensions therefore map to their originally
+ ratified states, with the exception of the I, Zicntr & Zihpm extensions.

-Intersil ISL12057 I2C RTC/Alarm chip
-
-ISL12057 is a trivial I2C device (it has simple device tree bindings,
-consisting of a compatible field, an address and possibly an interrupt
-line).
-
-Nonetheless, it also supports an option boolean property
-("wakeup-source") to handle the specific use-case found
-on at least three in-tree users of the chip (NETGEAR ReadyNAS 102, 104
-and 2120 ARM-based NAS); On those devices, the IRQ#2 pin of the chip
-(associated with the alarm supported by the driver) is not connected
-to the SoC but to a PMIC. It allows the device to be powered up when
-RTC alarm rings. In order to mark the device has a wakeup source and
-get access to the 'wakealarm' sysfs entry, this specific property can
-be set when the IRQ#2 pin of the chip is not connected to the SoC but
-can wake up the device.
-
-Required properties supported by the device:
-
- - "compatible": must be "isil,isl12057"
- - "reg": I2C bus address of the device
-
-Optional properties:
-
- - "wakeup-source": mark the chip as a wakeup source, independently of
- the availability of an IRQ line connected to the SoC.
-
-
-Example isl12057 node without IRQ#2 pin connected (no alarm support):
-
- isl12057: isl12057@68 {
- compatible = "isil,isl12057";
- reg = <0x68>;
- };
-
-
-Example isl12057 node with IRQ#2 pin connected to main SoC via MPP6 (note
-that the pinctrl-related properties below are given for completeness and
-may not be required or may be different depending on your system or
-SoC, and the main function of the MPP used as IRQ line, i.e.
-"interrupt-parent" and "interrupts" are usually sufficient):
-
- pinctrl {
- ...
-
- rtc_alarm_pin: rtc_alarm_pin {
- marvell,pins = "mpp6";
- marvell,function = "gpio";
- };
-

- interrupt-parent = <&gpio0>;

+title: Real Time Clock of the Sophgo CV1800 SoC
+
+description:
+ The RTC (Real Time Clock) is an independently powered module in the chip. It
+ contains a 32KHz oscillator and a Power-On-Reset (POR) sub-module, which can
+ be used for time display and scheduled alarm produce. In addition, the
+ hardware state machine provides triggering and timing control for chip
+ power-on, power-off and reset.
+
+ Furthermore, the 8051 subsystem is located within RTCSYS and is independently
+ powered. System software can use the 8051 to manage wake conditions and wake
+ the system while the system is asleep, and communicate with external devices
+ through peripheral controllers.

-Binding for Conexant Digicolor USART
-
-Note: this binding is only applicable for using the USART peripheral as
-UART. USART also support synchronous serial protocols like SPI and I2S. Use
-the binding that matches the wiring of your system.
-
-Required properties:
-- compatible : should be "cnxt,cx92755-usart".
-- reg: Should contain USART controller registers location and length.
-- interrupts: Should contain a single USART controller interrupt.
-- clocks: Must contain phandles to the USART clock
- See ../clocks/clock-bindings.txt for details.
-
-Note: Each UART port should have an alias correctly numbered
-in "aliases" node.
-
-Example:
- aliases {
- serial0 = &uart0;
- };
-
- uart0: uart@f0000740 {
- compatible = "cnxt,cx92755-usart";
- reg = <0xf0000740 0x20>;
- clocks = <&main_clk>;
- interrupts = <44>;

-* Marvell UART : Non standard UART used in some of Marvell EBU SoCs
- e.g., Armada-3700.
-
-Required properties:
-- compatible:
- - "marvell,armada-3700-uart" for the standard variant of the UART
- (32 bytes FIFO, no DMA, level interrupts, 8-bit access to the
- FIFO), called also UART1.
- - "marvell,armada-3700-uart-ext" for the extended variant of the
- UART (128 bytes FIFO, DMA, front interrupts, 8-bit or 32-bit
- accesses to the FIFO), called also UART2.
-- reg: offset and length of the register set for the device.
-- clocks: UART reference clock used to derive the baudrate. If no clock
- is provided (possible only with the "marvell,armada-3700-uart"
- compatible string for backward compatibility), it will only work
- if the baudrate was initialized by the bootloader and no baudrate
- change will then be possible. When provided it should be UART1-clk
- for standard variant of UART and UART2-clk for extended variant
- of UART. TBG clock (with UART TBG divisors d1=d2=1) or xtal clock
- should not be used and are supported only for backward compatibility.
-- interrupts:
- - Must contain three elements for the standard variant of the IP
- (marvell,armada-3700-uart): "uart-sum", "uart-tx" and "uart-rx",
- respectively the UART sum interrupt, the UART TX interrupt and
- UART RX interrupt. A corresponding interrupt-names property must
- be defined.
- - Must contain two elements for the extended variant of the IP
- (marvell,armada-3700-uart-ext): "uart-tx" and "uart-rx",
- respectively the UART TX interrupt and the UART RX interrupt. A
- corresponding interrupt-names property must be defined.
- - For backward compatibility reasons, a single element interrupts
- property is also supported for the standard variant of the IP,
- containing only the UART sum interrupt. This form is deprecated
- and should no longer be used.
-
-Example:
- uart0: serial@12000 {
- compatible = "marvell,armada-3700-uart";
- reg = <0x12000 0x18>;
- clocks = <&uartclk 0>;

-
-Optional properties:
-- nvidia,enable-modem-interrupt: Enable modem interrupts. Should be enable
- only if all 8 lines of UART controller are pinmuxed.
-- nvidia,adjust-baud-rates: List of entries providing percentage of baud rate
- adjustment within a range.
- Each entry contains sets of 3 values. Range low/high and adjusted rate.
- <range_low range_high adjusted_rate>
- When baud rate set on controller falls within the range mentioned in this
- field, baud rate will be adjusted by percentage mentioned here.
- Ex: <9600 115200 200>
- Increase baud rate by 2% when set baud rate falls within range 9600 to 115200
-
-Baud Rate tolerance:
- Standard UART devices are expected to have tolerance for baud rate error by
- -4 to +4 %. All Tegra devices till Tegra210 had this support. However,
- Tegra186 chip has a known hardware issue. UART Rx baud rate tolerance level
- is 0% to +4% in 1-stop config. Otherwise, the received data will have
- corruption/invalid framing errors. Parker errata suggests adjusting baud
- rate to be higher than the deviations observed in Tx.
-
- Tx deviation of connected device can be captured over scope (or noted from
- its spec) for valid range and Tegra baud rate has to be set above actual
- Tx baud rate observed. To do this we use nvidia,adjust-baud-rates
-
- As an example, consider there is deviation observed in Tx for baud rates as
- listed below.
- 0 to 9600 has 1% deviation
- 9600 to 115200 2% deviation
- This slight deviation is expcted and Tegra UART is expected to handle it. Due
- to the issue stated above, baud rate on Tegra UART should be set equal to or
- above deviation observed for avoiding frame errors.
- Property should be set like this
- nvidia,adjust-baud-rates = <0 9600 100>,

-Required properties:
-- compatible: Should be one of the following:
- - "nxp,sc16is740" for NXP SC16IS740,
- - "nxp,sc16is741" for NXP SC16IS741,
- - "nxp,sc16is750" for NXP SC16IS750,

- - "nxp,sc16is760" for NXP SC16IS760,
- - "nxp,sc16is762" for NXP SC16IS762.
-- reg: I2C address of the SC16IS7xx device.
-- interrupts: Should contain the UART interrupt
-- clocks: Reference to the IC source clock.
- OR (when there is no clock provider visible to the platform)
-- clock-frequency: The source clock frequency for the IC.
-
-Optional properties:
-- gpio-controller: Marks the device node as a GPIO controller.
-- #gpio-cells: Should be two. The first cell is the GPIO number and
- the second cell is used to specify the GPIO polarity:
- 0 = active high,
- 1 = active low.
-- irda-mode-ports: An array that lists the indices of the port that
- should operate in IrDA mode.
-
-Example:
- sc16is750: sc16is750@51 {

-
-The Buffer Manager is part of the Data-Path Acceleration Architecture (DPAA).
-BMan supports hardware allocation and deallocation of buffers belonging to pools
-originally created by software with configurable depletion thresholds. This
-binding covers the CCSR space programming model
-

- Definition: PAMU property used for dynamic LIODN assignment
-
- For additional details about the PAMU/LIODN binding(s) see pamu.txt
-
-Devices connected to a BMan instance via Direct Connect Portals (DCP) must link
-to the respective BMan instance
-
-- fsl,bman
- Usage: Required
- Value type: <prop-encoded-array>
- Description: List of phandle and DCP index pairs, to the BMan instance
- to which this device is connected via the DCP
-
-BMan Private Memory Node
-
-BMan requires a contiguous range of physical memory used for the backing store
-for BMan Free Buffer Proxy Records (FBPR). This memory is reserved/allocated as
-a node under the /reserved-memory node.
-
-The BMan FBPR memory node must be named "bman-fbpr"
-
-PROPERTIES
-
-- compatible
- Usage: required
- Value type: <stringlist>
- Definition: PPC platforms: Must include "fsl,bman-fbpr"
- ARM platforms: Must include "shared-dma-pool"
- as well as the "no-map" property
-
-The following constraints are relevant to the FBPR private memory:
- - The size must be 2^(size + 1), with size = 11..33. That is 4 KiB to
- 16 GiB
- - The alignment must be a muliptle of the memory size
-
-The size of the FBPR must be chosen by observing the hardware features configured
-via the Reset Configuration Word (RCW) and that are relevant to a specific board
-(e.g. number of MAC(s) pinned-out, number of offline/host command FMan ports,
-etc.). The size configured in the DT must reflect the hardware capabilities and
-not the specific needs of an application
-
-For additional details about reserved memory regions see reserved-memory.txt
-
-EXAMPLE
-
-The example below shows a BMan FBPR dynamic allocation memory node
-
- reserved-memory {
- #address-cells = <2>;
- #size-cells = <2>;
- ranges;
-
- bman_fbpr: bman-fbpr {
- compatible = "shared-mem-pool";
- size = <0 0x1000000>;
- alignment = <0 0x1000000>;
- no-map;
- };
- };
-
-The example below shows a (P4080) BMan CCSR-space node
-
- bportals: bman-portals@ff4000000 {
- ...

-* Freescale QUICC Engine module (QE)
-This represents qe module that is installed on PowerQUICC II Pro.
-
-NOTE: This is an interim binding; it should be updated to fit
-in with the CPM binding later in this document.
-
-Basically, it is a bus of devices, that could act more or less
-as a complete entity (UCC, USB etc ). All of them should be siblings on
-the "root" qe node, using the common properties from there.
-The description below applies to the qe of MPC8360 and
-more nodes and properties would be extended in the future.
-
-i) Root QE device
-
-Required properties:
-- compatible : should be "fsl,qe";
-- model : precise model of the QE, Can be "QE", "CPM", or "CPM2"
-- reg : offset and length of the device registers.
-- bus-frequency : the clock frequency for QUICC Engine.
-- fsl,qe-num-riscs: define how many RISC engines the QE has.
-- fsl,qe-snums: This property has to be specified as '/bits/ 8' value,
- defining the array of serial number (SNUM) values for the virtual
- threads.
-
-Optional properties:
-- fsl,firmware-phandle:
- Usage: required only if there is no fsl,qe-firmware child node
- Value type: <phandle>
- Definition: Points to a firmware node (see "QE Firmware Node" below)
- that contains the firmware that should be uploaded for this QE.
- The compatible property for the firmware node should say,
- "fsl,qe-firmware".
-
-Recommended properties
-- brg-frequency : the internal clock source frequency for baud-rate
- generators in Hz.
-
-Deprecated properties
-- fsl,qe-num-snums: define how many serial number(SNUM) the QE can use
- for the threads. Use fsl,qe-snums instead to not only specify the
- number of snums, but also their values.
-
-Example:
- qe@e0100000 {
- #address-cells = <1>;
- #size-cells = <1>;
- #interrupt-cells = <2>;
- compatible = "fsl,qe";
- ranges = <0 e0100000 00100000>;
- reg = <e0100000 480>;
- brg-frequency = <0>;
- bus-frequency = <179A7B00>;
- fsl,qe-snums = /bits/ 8 <
- 0x04 0x05 0x0C 0x0D 0x14 0x15 0x1C 0x1D
- 0x24 0x25 0x2C 0x2D 0x34 0x35 0x88 0x89
- 0x98 0x99 0xA8 0xA9 0xB8 0xB9 0xC8 0xC9
- 0xD8 0xD9 0xE8 0xE9>;
- }
-
-* Multi-User RAM (MURAM)
-
-Required properties:
-- compatible : should be "fsl,qe-muram", "fsl,cpm-muram".
-- mode : the could be "host" or "slave".
-- ranges : Should be defined as specified in 1) to describe the
- translation of MURAM addresses.
-- data-only : sub-node which defines the address area under MURAM
- bus that can be allocated as data/parameter
-
-Example:
-
- muram@10000 {
- compatible = "fsl,qe-muram", "fsl,cpm-muram";
- ranges = <0 00010000 0000c000>;
-
- data-only@0{
- compatible = "fsl,qe-muram-data",
- "fsl,cpm-muram-data";
- reg = <0 c000>;
- };
- };
-
-* Interrupt Controller (IC)
-
-Required properties:
-- compatible : should be "fsl,qe-ic".
-- reg : Address range of IC register set.
-- interrupts : interrupts generated by the device.
-- interrupt-controller : this device is a interrupt controller.
-
-Example:
-
- qeic: interrupt-controller@80 {
- interrupt-controller;
- compatible = "fsl,qe-ic";
- #address-cells = <0>;
- #interrupt-cells = <1>;
- reg = <0x80 0x80>;
- interrupts = <95 2 0 0 94 2 0 0>;
- };
-
-* Serial Interface Block (SI)
-
-The SI manages the routing of eight TDM lines to the QE block serial drivers
-, the MCC and the UCCs, for receive and transmit.
-
-Required properties:
-- compatible : must be "fsl,<chip>-qe-si". For t1040, must contain
- "fsl,t1040-qe-si".
-- reg : Address range of SI register set.
-
-Example:
-
- si1: si@700 {
- compatible = "fsl,t1040-qe-si";
- reg = <0x700 0x80>;
- };
-
-* Serial Interface Block RAM(SIRAM)
-
-store the routing entries of SI
-
-Required properties:
-- compatible : should be "fsl,<chip>-qe-siram". For t1040, must contain
- "fsl,t1040-qe-siram".
-- reg : Address range of SI RAM.
-
-Example:
-
- siram1: siram@1000 {
- compatible = "fsl,t1040-qe-siram";
- reg = <0x1000 0x800>;
- };
-
-* QE Firmware Node
-
-This node defines a firmware binary that is embedded in the device tree, for
-the purpose of passing the firmware from bootloader to the kernel, or from
-the hypervisor to the guest.
-
-The firmware node itself contains the firmware binary contents, a compatible
-property, and any firmware-specific properties. The node should be placed
-inside a QE node that needs it. Doing so eliminates the need for a
-fsl,firmware-phandle property. Other QE nodes that need the same firmware
-should define an fsl,firmware-phandle property that points to the firmware node
-in the first QE node.
-
-The fsl,firmware property can be specified in the DTS (possibly using incbin)
-or can be inserted by the boot loader at boot time.
-
-Required properties:
- - compatible
- Usage: required
- Value type: <string>
- Definition: A standard property. Specify a string that indicates what
- kind of firmware it is. For QE, this should be "fsl,qe-firmware".
-
- - fsl,firmware
- Usage: required
- Value type: <prop-encoded-array>, encoded as an array of bytes
- Definition: A standard property. This property contains the firmware
- binary "blob".
-
-Example:
- qe1@e0080000 {
- compatible = "fsl,qe";
- qe_firmware:qe-firmware {
- compatible = "fsl,qe-firmware";
- fsl,firmware = [0x70 0xcd 0x00 0x00 0x01 0x46 0x45 ...];
- };
- ...
- };
-
- qe2@e0090000 {
- compatible = "fsl,qe";
- fsl,firmware-phandle = <&qe_firmware>;
- ...
- };

+ This memory is reserved/allocated as a node under the /reserved-memory node.
+
+ BMan requires a contiguous range of physical memory used for the backing store
+ for BMan Free Buffer Proxy Records (FBPR). This memory is reserved/allocated as
+ a node under the /reserved-memory node.
+
+ The QMan FQD memory node must be named "qman-fqd"
+ The QMan PFDR memory node must be named "qman-pfdr"
+ The BMan FBPR memory node must be named "bman-fbpr"
+
+ The following constraints are relevant to the FQD and PFDR private memory:
+ - The size must be 2^(size + 1), with size = 11..29. That is 4 KiB to
+ 1 GiB
+ - The alignment must be a muliptle of the memory size
+
+ The size of the FQD and PFDP must be chosen by observing the hardware features
+ configured via the Reset Configuration Word (RCW) and that are relevant to a
+ specific board (e.g. number of MAC(s) pinned-out, number of offline/host command

-The following constraints are relevant to the FQD and PFDR private memory:
- - The size must be 2^(size + 1), with size = 11..29. That is 4 KiB to
- 1 GiB
- - The alignment must be a muliptle of the memory size
-
-The size of the FQD and PFDP must be chosen by observing the hardware features
-configured via the Reset Configuration Word (RCW) and that are relevant to a
-specific board (e.g. number of MAC(s) pinned-out, number of offline/host command
-FMan ports, etc.). The size configured in the DT must reflect the hardware

-* Run Control and Power Management
--------------------------------------------
-The RCPM performs all device-level tasks associated with device run control
-and power management.
-
-Required properites:
- - reg : Offset and length of the register set of the RCPM block.
- - #fsl,rcpm-wakeup-cells : The number of IPPDEXPCR register cells in the
- fsl,rcpm-wakeup property.
- - compatible : Must contain a chip-specific RCPM block compatible string
- and (if applicable) may contain a chassis-version RCPM compatible
- string. Chip-specific strings are of the form "fsl,<chip>-rcpm",
- such as:
- * "fsl,p2041-rcpm"
- * "fsl,p5020-rcpm"
- * "fsl,t4240-rcpm"
-
- Chassis-version strings are of the form "fsl,qoriq-rcpm-<version>",
- such as:
- * "fsl,qoriq-rcpm-1.0": for chassis 1.0 rcpm
- * "fsl,qoriq-rcpm-2.0": for chassis 2.0 rcpm
- * "fsl,qoriq-rcpm-2.1": for chassis 2.1 rcpm
- * "fsl,qoriq-rcpm-2.1+": for chassis 2.1+ rcpm
-
-All references to "1.0" and "2.0" refer to the QorIQ chassis version to
-which the chip complies.
-Chassis Version Example Chips
---------------- -------------------------------
-1.0 p4080, p5020, p5040, p2041, p3041
-2.0 t4240, b4860, b4420
-2.1 t1040,
-2.1+ ls1021a, ls1012a, ls1043a, ls1046a
-
-Optional properties:
- - little-endian : RCPM register block is Little Endian. Without it RCPM
- will be Big Endian (default case).
-
-Example:
-The RCPM node for T4240:
- rcpm: global-utilities@e2000 {
- compatible = "fsl,t4240-rcpm", "fsl,qoriq-rcpm-2.0";
- reg = <0xe2000 0x1000>;
- #fsl,rcpm-wakeup-cells = <2>;
- };
-
-* Freescale RCPM Wakeup Source Device Tree Bindings
--------------------------------------------
-Required fsl,rcpm-wakeup property should be added to a device node if the device
-can be used as a wakeup source.
-
- - fsl,rcpm-wakeup: Consists of a phandle to the rcpm node and the IPPDEXPCR
- register cells. The number of IPPDEXPCR register cells is defined in
- "#fsl,rcpm-wakeup-cells" in the rcpm node. The first register cell is
- the bit mask that should be set in IPPDEXPCR0, and the second register
- cell is for IPPDEXPCR1, and so on.
-
- Note: IPPDEXPCR(IP Powerdown Exception Control Register) provides a
- mechanism for keeping certain blocks awake during STANDBY and MEM, in
- order to use them as wake-up sources.
-
-Example:
- lpuart0: serial@2950000 {
- compatible = "fsl,ls1021a-lpuart";
- reg = <0x0 0x2950000 0x0 0x1000>;

+description: |
+ The Qualcomm RPM (Resource Power Manager) architecture includes a concept
+ of "RPM Masters". They can be thought of as "the local gang leaders", usually
+ spanning a single subsystem (e.g. APSS, ADSP, CDSP). All of the RPM decisions
+ (particularly around entering hardware-driven low power modes: XO shutdown
+ and total system-wide power collapse) are first made at Master-level, and
+ only then aggregated for the entire system.
+
+ The Master Stats provide a few useful bits that can be used to assess whether
+ our device has entered the desired low-power mode, how long it took to do so,
+ the duration of that residence, how long it took to come back online,
+ how many times a given sleep state was entered and which cores are actively
+ voting for staying awake.
+
+ This scheme has been used on various SoCs in the 2013-2023 era, with some
+ newer or higher-end designs providing this information through an SMEM query.

+ The USI IP-core provides configurable support for serial protocols, enabling

+ I2C1, SPI, UART, High-Speed I2C0 and I2C1 or both High-Speed
+ I2C1 and UART.
+
+ In USIv2, only one protocol can be active at a time, either UART, SPI, or

+ This is a pad configuration node. On Tegra SoCs a pad is a set of pins
+ which are configured as a group. The pin grouping is a fixed attribute
+ of the hardware. The PMC can be used to set pad power state and
+ signaling voltage. A pad can be either in active or power down mode.
+ The support for power state and signaling voltage configuration varies
+ depending on the pad in question. 3.3V and 1.8V signaling voltages are
+ supported on pins where software controllable signaling voltage
+ switching is available.
+
+ The pad configuration state nodes are placed under the pmc node and
+ they are referred to by the pinctrl client properties. For more
+ information see:
+
+ Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
+
+ The pad name should be used as the value of the pins property in pin
+ configuration nodes.

+ search using a specific compatible value), interrogate the node (or
+ associated OS driver) to determine the location of the registers,

-LogicoreIP designed compatible with Xilinx ZYNQ family.
--------------------------------------------------------
-
-General concept
----------------
-
-LogicoreIP design to provide the isolation between processing system
-and programmable logic. Also provides the list of register set to configure
-the frequency.
-
-Required properties:
-- compatible: shall be one of:
- "xlnx,vcu"
- "xlnx,vcu-logicoreip-1.0"
-- reg : The base offset and size of the VCU_PL_SLCR register space.
-- clocks: phandle for aclk and pll_ref clocksource
-- clock-names: The identification string, "aclk", is always required for
- the axi clock. "pll_ref" is required for pll.
-Example:
-
- xlnx_vcu: vcu@a0040000 {
- compatible = "xlnx,vcu-logicoreip-1.0";
- reg = <0x0 0xa0040000 0x0 0x1000>;
- clocks = <&si570_1>, <&clkc 71>;
- clock-names = "pll_ref", "aclk";

- line is de-asserted. That also means that clocks cannot be changed

- One (undocumented) workaround is to assert and de-assert the PDN bit
- in the MODE2 register. This workaround can be enabled with this DT
- property.

-* Dialog DA9055 Audio CODEC
-
-DA9055 provides Audio CODEC support (I2C only).
-
-The Audio CODEC device in DA9055 has its own I2C address which is configurable,
-so the device is instantiated separately from the PMIC (MFD) device.
-
-For details on accompanying PMIC I2C device, see the following:
-Documentation/devicetree/bindings/mfd/da9055.txt
-
-Required properties:
-
- - compatible: "dlg,da9055-codec"
- - reg: Specifies the I2C slave address
-
-
-Example:
-
- codec: da9055-codec@1a {
- compatible = "dlg,da9055-codec";
- reg = <0x1a>;

-Texas Instruments DaVinci McBSP module
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This binding describes the "Multi-channel Buffered Serial Port" (McBSP)
-audio interface found in some TI DaVinci processors like the OMAP-L138 or AM180x.
-
-
-Required properties:
-~~~~~~~~~~~~~~~~~~~~
-- compatible :
- "ti,da850-mcbsp" : for DA850, AM180x and OPAM-L138 platforms
-
-- reg : physical base address and length of the controller memory mapped
- region(s).
-- reg-names : Should contain:
- * "mpu" for the main registers (required).
- * "dat" for the data FIFO (optional).
-
-- dmas: three element list of DMA controller phandles, DMA request line and
- TC channel ordered triplets.
-- dma-names: identifier string for each DMA request line in the dmas property.
- These strings correspond 1:1 with the ordered pairs in dmas. The dma
- identifiers must be "rx" and "tx".
-
-Optional properties:
-~~~~~~~~~~~~~~~~~~~~
-- interrupts : Interrupt numbers for McBSP
-- interrupt-names : Known interrupt names are "rx" and "tx"
-
-- pinctrl-0: Should specify pin control group used for this controller.
-- pinctrl-names: Should contain only one value - "default", for more details
- please refer to pinctrl-bindings.txt

-Freescale Asynchronous Sample Rate Converter (ASRC) Controller
-
-The Asynchronous Sample Rate Converter (ASRC) converts the sampling rate of a
-signal associated with an input clock into a signal associated with a different
-output clock. The driver currently works as a Front End of DPCM with other Back
-Ends Audio controller such as ESAI, SSI and SAI. It has three pairs to support
-three substreams within totally 10 channels.
-
-Required properties:
-
- - compatible : Compatible list, should contain one of the following
- compatibles:
- "fsl,imx35-asrc",
- "fsl,imx53-asrc",
- "fsl,imx8qm-asrc",
- "fsl,imx8qxp-asrc",
-
- - reg : Offset and length of the register set for the device.
-
- - interrupts : Contains the spdif interrupt.
-
- - dmas : Generic dma devicetree binding as described in
- Documentation/devicetree/bindings/dma/dma.txt.
-
- - dma-names : Contains "rxa", "rxb", "rxc", "txa", "txb" and "txc".
-
- - clocks : Contains an entry for each entry in clock-names.
-
- - clock-names : Contains the following entries
- "mem" Peripheral access clock to access registers.
- "ipg" Peripheral clock to driver module.
- "asrck_<0-f>" Clock sources for input and output clock.
- "spba" The spba clock is required when ASRC is placed as a
- bus slave of the Shared Peripheral Bus and when two
- or more bus masters (CPU, DMA or DSP) try to access
- it. This property is optional depending on the SoC
- design.
-
- - fsl,asrc-rate : Defines a mutual sample rate used by DPCM Back Ends.
-
- - fsl,asrc-width : Defines a mutual sample width used by DPCM Back Ends.
-
- - fsl,asrc-clk-map : Defines clock map used in driver. which is required
- by imx8qm/imx8qxp platform
- <0> - select the map for asrc0 in imx8qm/imx8qxp
- <1> - select the map for asrc1 in imx8qm/imx8qxp
-
-Optional properties:
-
- - big-endian : If this property is absent, the little endian mode
- will be in use as default. Otherwise, the big endian
- mode will be in use for all the device registers.
-
- - fsl,asrc-format : Defines a mutual sample format used by DPCM Back
- Ends, which can replace the fsl,asrc-width.
- The value is 2 (S16_LE), or 6 (S24_LE).
-
-Example:
-

-NXP Audio Mixer (AUDMIX).
-
-The Audio Mixer is a on-chip functional module that allows mixing of two
-audio streams into a single audio stream. Audio Mixer has two input serial
-audio interfaces. These are driven by two Synchronous Audio interface
-modules (SAI). Each input serial interface carries 8 audio channels in its
-frame in TDM manner. Mixer mixes audio samples of corresponding channels
-from two interfaces into a single sample. Before mixing, audio samples of
-two inputs can be attenuated based on configuration. The output of the
-Audio Mixer is also a serial audio interface. Like input interfaces it has
-the same TDM frame format. This output is used to drive the serial DAC TDM
-interface of audio codec and also sent to the external pins along with the
-receive path of normal audio SAI module for readback by the CPU.
-
-The output of Audio Mixer can be selected from any of the three streams
- - serial audio input 1
- - serial audio input 2
- - mixed audio
-
-Mixing operation is independent of audio sample rate but the two audio
-input streams must have same audio sample rate with same number of channels
-in TDM frame to be eligible for mixing.
-
-Device driver required properties:
-=================================
- - compatible : Compatible list, contains "fsl,imx8qm-audmix"
-
- - reg : Offset and length of the register set for the device.
-
- - clocks : Must contain an entry for each entry in clock-names.
-
- - clock-names : Must include the "ipg" for register access.
-
- - power-domains : Must contain the phandle to AUDMIX power domain node
-
- - dais : Must contain a list of phandles to AUDMIX connected
- DAIs. The current implementation requires two phandles
- to SAI interfaces to be provided, the first SAI in the
- list being used to route the AUDMIX output.
-
-Device driver configuration example:
-======================================
- audmix: audmix@59840000 {
- compatible = "fsl,imx8qm-audmix";
- reg = <0x0 0x59840000 0x0 0x10000>;
- clocks = <&clk IMX8QXP_AUD_AUDMIX_IPG>;
- clock-names = "ipg";
- power-domains = <&pd_audmix>;
- dais = <&sai4>, <&sai5>;

-Freescale Enhanced Serial Audio Interface (ESAI) Controller
-
-The Enhanced Serial Audio Interface (ESAI) provides a full-duplex serial port
-for serial communication with a variety of serial devices, including industry
-standard codecs, Sony/Phillips Digital Interface (S/PDIF) transceivers, and
-other DSPs. It has up to six transmitters and four receivers.
-
-Required properties:
-
- - compatible : Compatible list, should contain one of the following
- compatibles:
- "fsl,imx35-esai",
- "fsl,vf610-esai",
- "fsl,imx6ull-esai",
- "fsl,imx8qm-esai",
-
- - reg : Offset and length of the register set for the device.
-
- - interrupts : Contains the spdif interrupt.
-
- - dmas : Generic dma devicetree binding as described in
- Documentation/devicetree/bindings/dma/dma.txt.
-
- - dma-names : Two dmas have to be defined, "tx" and "rx".
-
- - clocks : Contains an entry for each entry in clock-names.
-
- - clock-names : Includes the following entries:
- "core" The core clock used to access registers
- "extal" The esai baud clock for esai controller used to
- derive HCK, SCK and FS.
- "fsys" The system clock derived from ahb clock used to
- derive HCK, SCK and FS.
- "spba" The spba clock is required when ESAI is placed as a
- bus slave of the Shared Peripheral Bus and when two
- or more bus masters (CPU, DMA or DSP) try to access
- it. This property is optional depending on the SoC
- design.
-
- - fsl,fifo-depth : The number of elements in the transmit and receive
- FIFOs. This number is the maximum allowed value for
- TFCR[TFWM] or RFCR[RFWM].
-
- - fsl,esai-synchronous: This is a boolean property. If present, indicating
- that ESAI would work in the synchronous mode, which
- means all the settings for Receiving would be
- duplicated from Transmition related registers.
-
-Optional properties:
-
- - big-endian : If this property is absent, the native endian mode
- will be in use as default, or the big endian mode
- will be in use for all the device registers.
-
-Example:
-
-esai: esai@2024000 {
- compatible = "fsl,imx35-esai";
- reg = <0x02024000 0x4000>;
- interrupts = <0 51 0x04>;

-Freescale Synchronous Serial Interface
-
-The SSI is a serial device that communicates with audio codecs. It can
-be programmed in AC97, I2S, left-justified, or right-justified modes.
-
-Required properties:
-- compatible: Compatible list, should contain one of the following
- compatibles:
- fsl,mpc8610-ssi
- fsl,imx51-ssi
- fsl,imx35-ssi
- fsl,imx21-ssi
-- cell-index: The SSI, <0> = SSI1, <1> = SSI2, and so on.
-- reg: Offset and length of the register set for the device.
-- interrupts: <a b> where a is the interrupt number and b is a
- field that represents an encoding of the sense and
- level information for the interrupt. This should be
- encoded based on the information in section 2)
- depending on the type of interrupt controller you
- have.
-- fsl,fifo-depth: The number of elements in the transmit and receive FIFOs.
- This number is the maximum allowed value for SFCSR[TFWM0].
- - clocks: "ipg" - Required clock for the SSI unit
- "baud" - Required clock for SSI master mode. Otherwise this
- clock is not used
-
-Required are also ac97 link bindings if ac97 is used. See
-Documentation/devicetree/bindings/sound/soc-ac97link.txt for the necessary
-bindings.
-
-Optional properties:
-- codec-handle: Phandle to a 'codec' node that defines an audio
- codec connected to this SSI. This node is typically
- a child of an I2C or other control node.
-- fsl,fiq-stream-filter: Bool property. Disabled DMA and use FIQ instead to
- filter the codec stream. This is necessary for some boards
- where an incompatible codec is connected to this SSI, e.g.
- on pca100 and pcm043.
-- dmas: Generic dma devicetree binding as described in
- Documentation/devicetree/bindings/dma/dma.txt.
-- dma-names: Two dmas have to be defined, "tx" and "rx", if fsl,imx-fiq
- is not defined.
-- fsl,mode: The operating mode for the AC97 interface only.
- "ac97-slave" - AC97 mode, SSI is clock slave
- "ac97-master" - AC97 mode, SSI is clock master
-- fsl,ssi-asynchronous:
- If specified, the SSI is to be programmed in asynchronous
- mode. In this mode, pins SRCK, STCK, SRFS, and STFS must
- all be connected to valid signals. In synchronous mode,
- SRCK and SRFS are ignored. Asynchronous mode allows
- playback and capture to use different sample sizes and
- sample rates. Some drivers may require that SRCK and STCK
- be connected together, and SRFS and STFS be connected
- together. This would still allow different sample sizes,
- but not different sample rates.
-- fsl,playback-dma: Phandle to a node for the DMA channel to use for
- playback of audio. This is typically dictated by SOC
- design. See the notes below.
- Only used on Power Architecture.
-- fsl,capture-dma: Phandle to a node for the DMA channel to use for
- capture (recording) of audio. This is typically dictated
- by SOC design. See the notes below.
- Only used on Power Architecture.
-
-Child 'codec' node required properties:
-- compatible: Compatible list, contains the name of the codec
-
-Child 'codec' node optional properties:
-- clock-frequency: The frequency of the input clock, which typically comes
- from an on-board dedicated oscillator.
-
-Notes on fsl,playback-dma and fsl,capture-dma:
-
-On SOCs that have an SSI, specific DMA channels are hard-wired for playback
-and capture. On the MPC8610, for example, SSI1 must use DMA channel 0 for
-playback and DMA channel 1 for capture. SSI2 must use DMA channel 2 for
-playback and DMA channel 3 for capture. The developer can choose which
-DMA controller to use, but the channels themselves are hard-wired. The
-purpose of these two properties is to represent this hardware design.
-
-The device tree nodes for the DMA channels that are referenced by
-"fsl,playback-dma" and "fsl,capture-dma" must be marked as compatible with
-"fsl,ssi-dma-channel". The SOC-specific compatible string (e.g.
-"fsl,mpc8610-dma-channel") can remain. If these nodes are left as
-"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel", then the generic Elo DMA
-drivers (fsldma) will attempt to use them, and it will conflict with the
-sound drivers.

-Freescale Generic ASoC Sound Card with ASRC support
-
-The Freescale Generic ASoC Sound Card can be used, ideally, for all Freescale
-SoCs connecting with external CODECs.
-
-The idea of this generic sound card is a bit like ASoC Simple Card. However,
-for Freescale SoCs (especially those released in recent years), most of them
-have ASRC (Documentation/devicetree/bindings/sound/fsl,asrc.txt) inside. And
-this is a specific feature that might be painstakingly controlled and merged
-into the Simple Card.
-
-So having this generic sound card allows all Freescale SoC users to benefit
-from the simplification of a new card support and the capability of the wide
-sample rates support through ASRC.
-
-Note: The card is initially designed for those sound cards who use AC'97, I2S
- and PCM DAI formats. However, it'll be also possible to support those non
- AC'97/I2S/PCM type sound cards, such as S/PDIF audio and HDMI audio, as
- long as the driver has been properly upgraded.
-
-
-The compatible list for this generic sound card currently:
- "fsl,imx-audio-ac97"
-
- "fsl,imx-audio-cs42888"
-
- "fsl,imx-audio-cs427x"
- (compatible with CS4271 and CS4272)
-
- "fsl,imx-audio-wm8962"
-
- "fsl,imx-audio-sgtl5000"
- (compatible with Documentation/devicetree/bindings/sound/imx-audio-sgtl5000.txt)
-
- "fsl,imx-audio-wm8960"
-
- "fsl,imx-audio-mqs"
-
- "fsl,imx-audio-wm8524"
-
- "fsl,imx-audio-tlv320aic32x4"
-
- "fsl,imx-audio-tlv320aic31xx"
-
- "fsl,imx-audio-si476x"
-
- "fsl,imx-audio-wm8958"
-
-Required properties:
-
- - compatible : Contains one of entries in the compatible list.
-
- - model : The user-visible name of this sound complex
-
- - audio-cpu : The phandle of an CPU DAI controller
-
- - audio-codec : The phandle of an audio codec
-
-Optional properties:
-
- - audio-asrc : The phandle of ASRC. It can be absent if there's no
- need to add ASRC support via DPCM.
-
- - audio-routing : A list of the connections between audio components.
- Each entry is a pair of strings, the first being the
- connection's sink, the second being the connection's
- source. There're a few pre-designed board connectors:
- * Line Out Jack
- * Line In Jack
- * Headphone Jack
- * Mic Jack
- * Ext Spk
- * AMIC (stands for Analog Microphone Jack)
- * DMIC (stands for Digital Microphone Jack)
-
- Note: The "Mic Jack" and "AMIC" are redundant while
- coexisting in order to support the old bindings
- of wm8962 and sgtl5000.
-
- - hp-det-gpio : The GPIO that detect headphones are plugged in
- - mic-det-gpio : The GPIO that detect microphones are plugged in
- - bitclock-master : Indicates dai-link bit clock master; for details see simple-card.yaml.
- - frame-master : Indicates dai-link frame master; for details see simple-card.yaml.
- - dai-format : audio format, for details see simple-card.yaml.
- - frame-inversion : dai-link uses frame clock inversion, for details see simple-card.yaml.
- - bitclock-inversion : dai-link uses bit clock inversion, for details see simple-card.yaml.
- - mclk-id : main clock id, specific for each card configuration.
-
-Optional unless SSI is selected as a CPU DAI:
-
- - mux-int-port : The internal port of the i.MX audio muxer (AUDMUX)
-
- - mux-ext-port : The external port of the i.MX audio muxer
-
-Example:
-sound-cs42888 {
- compatible = "fsl,imx-audio-cs42888";
- model = "cs42888-audio";
- audio-cpu = <&esai>;
- audio-asrc = <&asrc>;
- audio-codec = <&cs42888>;
- audio-routing =
- "Line Out Jack", "AOUT1L",
- "Line Out Jack", "AOUT1R",
- "Line Out Jack", "AOUT2L",
- "Line Out Jack", "AOUT2R",
- "Line Out Jack", "AOUT3L",
- "Line Out Jack", "AOUT3R",
- "Line Out Jack", "AOUT4L",
- "Line Out Jack", "AOUT4R",
- "AIN1L", "Line In Jack",
- "AIN1R", "Line In Jack",
- "AIN2L", "Line In Jack",
- "AIN2R", "Line In Jack";

-Invensense ICS-43432-compatible MEMS microphone with I2S output.
-
-There are no software configuration options for this device, indeed, the only
-host connection is the I2S interface. Apart from requirements on clock
-frequency (460 kHz to 3.379 MHz according to the data sheet) there must be
-64 clock cycles in each stereo output frame; 24 of the 32 available bits
-contain audio data. A hardware pin determines if the device outputs data
-on the left or right channel of the I2S frame.
-
-Required properties:
- - compatible: should be one of the following.
- "invensense,ics43432": For the Invensense ICS43432
- "cui,cmm-4030d-261": For the CUI CMM-4030D-261-I2S-TR
