-What: /sys/class/dax/
-Date: May, 2016
-KernelVersion: v4.7
-Contact: nvdimm@lists.linux.dev
-Description: Device DAX is the device-centric analogue of Filesystem
- DAX (CONFIG_FS_DAX). It allows memory ranges to be
- allocated and mapped without need of an intervening file
- system. Device DAX is strict, precise and predictable.
- Specifically this interface:
-
- 1. Guarantees fault granularity with respect to a given
- page size (pte, pmd, or pud) set at configuration time.
-
- 2. Enforces deterministic behavior by being strict about
- what fault scenarios are supported.
-
- The /sys/class/dax/ interface enumerates all the
- device-dax instances in the system. The ABI is
- deprecated and will be removed after 2020. It is
- replaced with the DAX bus interface /sys/bus/dax/ where
- device-dax instances can be found under
- /sys/bus/dax/devices/

+Description:
+ Storage devices may report a physical block size that is
+ bigger than the logical block size (for instance a drive
+ with 4KB physical sectors exposing 512-byte logical
+ blocks to the operating system). This parameter
+ indicates how many bytes the beginning of the device is

+Description:
+ The /sys/block/<disk>/diskseq files reports the disk
+ sequence number, which is a monotonically increasing
+ number assigned to every drive.
+ Some devices, like the loop device, refresh such number
+ every time the backing file is changed.
+ The value type is 64 bit unsigned.

+What: /sys/block/<disk>/inflight
+Date: October 2009
+Contact: Jens Axboe <axboe@kernel.dk>, Nikanth Karthikesan <knikanth@suse.de>
+Description:
+ Reports the number of I/O requests currently in progress
+ (pending / in flight) in a device driver. This can be less
+ than the number of requests queued in the block device queue.
+ The report contains 2 fields: one for read requests
+ and one for write requests.
+ The value type is unsigned int.
+ Cf. Documentation/block/stat.rst which contains a single value for
+ requests in flight.
+ This is related to /sys/block/<disk>/queue/nr_requests
+ and for SCSI device also its queue_depth.

+Description:
+ [RO] The presence of this sub-directory of the
+ /sys/block/xxx/queue/ directory indicates that the device is
+ capable of executing requests targeting different sector ranges
+ in parallel. For instance, single LUN multi-actuator hard-disks
+ will have an independent_access_ranges directory if the device
+ correctly advertizes the sector ranges of its actuators.
+
+ The independent_access_ranges directory contains one directory
+ per access range, with each range described using the sector
+ (RO) attribute file to indicate the first sector of the range
+ and the nr_sectors (RO) attribute file to indicate the total
+ number of sectors in the range starting from the first sector of
+ the range. For example, a dual-actuator hard-disk will have the
+ following independent_access_ranges entries.::
+
+ $ tree /sys/block/<disk>/queue/independent_access_ranges/
+ /sys/block/<disk>/queue/independent_access_ranges/
+ |-- 0
+ | |-- nr_sectors
+ | `-- sector
+ `-- 1
+ |-- nr_sectors
+ `-- sector
+
+ The sector and nr_sectors attributes use 512B sector unit,
+ regardless of the actual block size of the device. Independent
+ access ranges do not overlap and include all sectors within the
+ device capacity. The access ranges are numbered in increasing
+ order of the range start sector, that is, the sector attribute
+ of range 0 always has the value 0.

+Description:
+ [RW] If polling is enabled, this controls what kind of polling

+ In this mode, the CPU will repeatedly ask for completions
+ without giving up any time. If set to 0, a hybrid polling mode
+ is used, where the kernel will attempt to make an educated guess
+ at when the IO will complete. Based on this guess, the kernel
+ will put the process issuing IO to sleep for an amount of time,
+ before entering a classic poll loop. This mode might be a little
+ slower than pure classic polling, but it will be more efficient.

-Description:
- Storage devices may report a physical block size that is
- bigger than the logical block size (for instance a drive
- with 4KB physical sectors exposing 512-byte logical
- blocks to the operating system). This parameter
- indicates how many bytes the beginning of the device is

-
-What: /sys/block/<disk>/queue/physical_block_size
-Date: May 2009
-Contact: Martin K. Petersen <martin.petersen@oracle.com>
-Description:
- This is the smallest unit a physical storage device can
- write atomically. It is usually the same as the logical
- block size but may be bigger. One example is SATA
- drives with 4KB sectors that expose a 512-byte logical
- block size to the operating system. For stacked block
- devices the physical_block_size variable contains the
- maximum physical_block_size of the component devices.
-
-What: /sys/block/<disk>/queue/minimum_io_size
-Date: April 2009
-Contact: Martin K. Petersen <martin.petersen@oracle.com>
-Description:
- Storage devices may report a granularity or preferred
- minimum I/O size which is the smallest request the
- device can perform without incurring a performance
- penalty. For disk drives this is often the physical
- block size. For RAID arrays it is often the stripe
- chunk size. A properly aligned multiple of
- minimum_io_size is the preferred request size for
- workloads where a high number of I/O operations is
- desired.
-
-What: /sys/block/<disk>/queue/optimal_io_size
-Date: April 2009
-Contact: Martin K. Petersen <martin.petersen@oracle.com>
-Description:
- Storage devices may report an optimal I/O size, which is
- the device's preferred unit for sustained I/O. This is
- rarely reported for disk drives. For RAID arrays it is
- usually the stripe width or the internal track size. A
- properly aligned multiple of optimal_io_size is the
- preferred request size for workloads where sustained
- throughput is desired. If no optimal I/O size is
- reported this file contains 0.
-
-What: /sys/block/<disk>/queue/nomerges
-Date: January 2010
-Contact:
-Description:
- Standard I/O elevator operations include attempts to
- merge contiguous I/Os. For known random I/O loads these
- attempts will always fail and result in extra cycles
- being spent in the kernel. This allows one to turn off
- this behavior on one of two ways: When set to 1, complex
- merge checks are disabled, but the simple one-shot merges
- with the previous I/O request are enabled. When set to 2,
- all merge tries are disabled. The default value is 0 -
- which enables all types of merge tries.

-What: /sys/block/<disk>/discard_alignment
-Date: May 2011
-Contact: Martin K. Petersen <martin.petersen@oracle.com>
-Description:
- Devices that support discard functionality may
- internally allocate space in units that are bigger than
- the exported logical block size. The discard_alignment
- parameter indicates how many bytes the beginning of the
- device is offset from the internal allocation unit's
- natural alignment.

-
-What: /sys/block/<disk>/queue/discard_granularity
-Date: May 2011
-Contact: Martin K. Petersen <martin.petersen@oracle.com>
-Description:
- Devices that support discard functionality may
- internally allocate space using units that are bigger
- than the logical block size. The discard_granularity
- parameter indicates the size of the internal allocation
- unit in bytes if reported by the device. Otherwise the
- discard_granularity will be set to match the device's
- physical block size. A discard_granularity of 0 means
- that the device does not support discard functionality.
-
-What: /sys/block/<disk>/queue/discard_max_bytes
-Date: May 2011
-Contact: Martin K. Petersen <martin.petersen@oracle.com>
-Description:
- Devices that support discard functionality may have
- internal limits on the number of bytes that can be
- trimmed or unmapped in a single operation. Some storage
- protocols also have inherent limits on the number of
- blocks that can be described in a single command. The
- discard_max_bytes parameter is set by the device driver
- to the maximum number of bytes that can be discarded in
- a single operation. Discard requests issued to the
- device must not exceed this limit. A discard_max_bytes
- value of 0 means that the device does not support
- discard functionality.

- for discards, and don't read this file.
-
-What: /sys/block/<disk>/queue/write_same_max_bytes
-Date: January 2012
-Contact: Martin K. Petersen <martin.petersen@oracle.com>
-Description:
- Some devices support a write same operation in which a
- single data block can be written to a range of several
- contiguous blocks on storage. This can be used to wipe
- areas on disk or to initialize drives in a RAID
- configuration. write_same_max_bytes indicates how many
- bytes can be written in a single write same command. If
- write_same_max_bytes is 0, write same is not supported
- by the device.
-
-What: /sys/block/<disk>/queue/write_zeroes_max_bytes
-Date: November 2016
-Contact: Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com>
-Description:
- Devices that support write zeroes operation in which a
- single request can be issued to zero out the range of
- contiguous blocks on storage without having any payload
- in the request. This can be used to optimize writing zeroes
- to the devices. write_zeroes_max_bytes indicates how many
- bytes can be written in a single write zeroes command. If
- write_zeroes_max_bytes is 0, write zeroes is not supported
- by the device.
-
-What: /sys/block/<disk>/queue/zoned
-Date: September 2016
-Contact: Damien Le Moal <damien.lemoal@wdc.com>
-Description:
- zoned indicates if the device is a zoned block device
- and the zone model of the device if it is indeed zoned.
- The possible values indicated by zoned are "none" for
- regular block devices and "host-aware" or "host-managed"
- for zoned block devices. The characteristics of
- host-aware and host-managed zoned block devices are
- described in the ZBC (Zoned Block Commands) and ZAC
- (Zoned Device ATA Command Set) standards. These standards
- also define the "drive-managed" zone model. However,
- since drive-managed zoned block devices do not support
- zone commands, they will be treated as regular block
- devices and zoned will report "none".
-
-What: /sys/block/<disk>/queue/nr_zones
-Date: November 2018
-Contact: Damien Le Moal <damien.lemoal@wdc.com>
-Description:
- nr_zones indicates the total number of zones of a zoned block
- device ("host-aware" or "host-managed" zone model). For regular
- block devices, the value is always 0.
-
-What: /sys/block/<disk>/queue/max_active_zones
-Date: July 2020
-Contact: Niklas Cassel <niklas.cassel@wdc.com>
-Description:
- For zoned block devices (zoned attribute indicating
- "host-managed" or "host-aware"), the sum of zones belonging to
- any of the zone states: EXPLICIT OPEN, IMPLICIT OPEN or CLOSED,
- is limited by this value. If this value is 0, there is no limit.

-
-What: /sys/block/<disk>/queue/chunk_sectors
-Date: September 2016
-Contact: Hannes Reinecke <hare@suse.com>
-Description:
- chunk_sectors has different meaning depending on the type
- of the disk. For a RAID device (dm-raid), chunk_sectors
- indicates the size in 512B sectors of the RAID volume
- stripe segment. For a zoned block device, either
- host-aware or host-managed, chunk_sectors indicates the
- size in 512B sectors of the zones of the device, with
- the eventual exception of the last zone of the device
- which may be smaller.
-
-What: /sys/block/<disk>/queue/io_timeout
-Date: November 2018
-Contact: Weiping Zhang <zhangweiping@didiglobal.com>
-Description:
- io_timeout is the request timeout in milliseconds. If a request
- does not complete in this time then the block driver timeout
- handler is invoked. That timeout handler can decide to retry
- the request, to fail it or to start a device recovery strategy.

+7. ANALOGY WITH REFERENCE COUNTING
+-----------------------------------
+
+The reader-writer analogy (illustrated by the previous section) is not
+always the best way to think about using RCU. Another helpful analogy
+considers RCU an effective reference count on everything which is
+protected by RCU.
+
+A reference count typically does not prevent the referenced object's
+values from changing, but does prevent changes to type -- particularly the
+gross change of type that happens when that object's memory is freed and
+re-allocated for some other purpose. Once a type-safe reference to the
+object is obtained, some other mechanism is needed to ensure consistent
+access to the data in the object. This could involve taking a spinlock,
+but with RCU the typical approach is to perform reads with SMP-aware
+operations such as smp_load_acquire(), to perform updates with atomic
+read-modify-write operations, and to provide the necessary ordering.
+RCU provides a number of support functions that embed the required
+operations and ordering, such as the list_for_each_entry_rcu() macro
+used in the previous section.
+
+A more focused view of the reference counting behavior is that,
+between rcu_read_lock() and rcu_read_unlock(), any reference taken with
+rcu_dereference() on a pointer marked as ``__rcu`` can be treated as
+though a reference-count on that object has been temporarily increased.
+This prevents the object from changing type. Exactly what this means
+will depend on normal expectations of objects of that type, but it
+typically includes that spinlocks can still be safely locked, normal
+reference counters can be safely manipulated, and ``__rcu`` pointers
+can be safely dereferenced.
+
+Some operations that one might expect to see on an object for
+which an RCU reference is held include:
+
+ - Copying out data that is guaranteed to be stable by the object's type.
+ - Using kref_get_unless_zero() or similar to get a longer-term
+ reference. This may fail of course.
+ - Acquiring a spinlock in the object, and checking if the object still
+ is the expected object and if so, manipulating it freely.
+
+The understanding that RCU provides a reference that only prevents a
+change of type is particularly visible with objects allocated from a
+slab cache marked ``SLAB_TYPESAFE_BY_RCU``. RCU operations may yield a
+reference to an object from such a cache that has been concurrently
+freed and the memory reallocated to a completely different object,
+though of the same type. In this case RCU doesn't even protect the
+identity of the object from changing, only its type. So the object
+found may not be the one expected, but it will be one where it is safe
+to take a reference or spinlock and then confirm that the identity
+matches the expectations.
+
+With traditional reference counting -- such as that implemented by the
+kref library in Linux -- there is typically code that runs when the last
+reference to an object is dropped. With kref, this is the function
+passed to kref_put(). When RCU is being used, such finalization code
+must not be run until all ``__rcu`` pointers referencing the object have
+been updated, and then a grace period has passed. Every remaining
+globally visible pointer to the object must be considered to be a
+potential counted reference, and the finalization code is typically run
+using call_rcu() only after all those pointers have been changed.
+
+To see how to choose between these two analogies -- of RCU as a
+reader-writer lock and RCU as a reference counting system -- it is useful
+to reflect on the scale of the thing being protected. The reader-writer
+lock analogy looks at larger multi-part objects such as a linked list
+and shows how RCU can facilitate concurrency while elements are added
+to, and removed from, the list. The reference-count analogy looks at
+the individual objects and looks at how they can be accessed safely
+within whatever whole they are a part of.

+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 chip is instantiated, this hierarchy
+will be translated to appropriate device properties. The general structure is:
+
+**Group:** ``/config/gpio-sim``
+
+This is the top directory of the gpio-sim configfs tree.
+
+**Group:** ``/config/gpio-sim/gpio-device``
+
+**Attribute:** ``/config/gpio-sim/gpio-device/dev_name``
+
+**Attribute:** ``/config/gpio-sim/gpio-device/live``
+
+This is a directory representing a GPIO platform device. The ``'dev_name'``
+attribute is read-only and allows the user-space to read the platform device
+name (e.g. ``'gpio-sim.0'``). 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 simulated device and ``'0'`` to disable and tear
+it down.
+
+**Group:** ``/config/gpio-sim/gpio-device/gpio-bankX``
+
+**Attribute:** ``/config/gpio-sim/gpio-device/gpio-bankX/chip_name``
+
+**Attribute:** ``/config/gpio-sim/gpio-device/gpio-bankX/num_lines``
+
+This group represents a bank of GPIOs under the top platform device. The
+``'chip_name'`` attribute is read-only and allows the user-space to read the
+device name of the bank device. The ``'num_lines'`` attribute allows to specify
+the number of lines exposed by this bank.
+
+**Group:** ``/config/gpio-sim/gpio-device/gpio-bankX/lineY``
+
+**Attribute:** ``/config/gpio-sim/gpio-device/gpio-bankX/lineY/name``
+
+This group represents a single line at the offset Y. The 'name' attribute
+allows to set the line name as represented by the 'gpio-line-names' property.
+
+**Item:** ``/config/gpio-sim/gpio-device/gpio-bankX/lineY/hog``
+
+**Attribute:** ``/config/gpio-sim/gpio-device/gpio-bankX/lineY/hog/name``
+
+**Attribute:** ``/config/gpio-sim/gpio-device/gpio-bankX/lineY/hog/direction``
+
+This item makes the gpio-sim module hog the associated line. The ``'name'``
+attribute specifies the in-kernel consumer name to use. The ``'direction'``
+attribute specifies the hog direction and must be one of: ``'input'``,
+``'output-high'`` and ``'output-low'``.
+
+Inside each bank directory, there's a set of attributes that can be used to
+configure the new chip. Additionally the user can ``mkdir()`` subdirectories
+inside the chip's directory that allow to pass additional configuration for
+specific lines. The name of those subdirectories must take the form of:
+``'line<offset>'`` (e.g. ``'line0'``, ``'line20'``, etc.) as the name will be
+used by the module to assign the config to the specific line at given offset.
+
+Once the confiuration is complete, the ``'live'`` attribute must be set to 1 in
+order to instantiate the chip. It can be set back to 0 to destroy the simulated
+chip. 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.
+
+Simulated GPIO chips can also be defined in device-tree. The compatible string
+must be: ``"gpio-simulator"``. Supported properties are:
+
+ ``"gpio-sim,label"`` - chip label
+
+Other standard GPIO properties (like ``"gpio-line-names"``, ``"ngpios"`` or
+``"gpio-hog"``) are also supported. Please refer to the GPIO documentation for
+details.
+
+An example device-tree code defining a GPIO simulator:
+
+.. code-block :: none
+
+ gpio-sim {
+ compatible = "gpio-simulator";
+
+ bank0 {
+ gpio-controller;
+ #gpio-cells = <2>;
+ ngpios = <16>;
+ gpio-sim,label = "dt-bank0";
+ gpio-line-names = "", "sim-foo", "", "sim-bar";
+ };
+
+ bank1 {
+ gpio-controller;
+ #gpio-cells = <2>;
+ ngpios = <8>;
+ gpio-sim,label = "dt-bank1";
+
+ line3 {
+ gpio-hog;
+ gpios = <3 0>;
+ output-high;
+ line-name = "sim-hog-from-dt";
+ };
+ };
+ };
+
+Manipulating simulated lines
+----------------------------
+
+Each simulated GPIO chip creates a separate sysfs group under its device
+directory for each exposed line
+(e.g. ``/sys/devices/platform/gpio-sim.X/gpiochipY/``). The name of each group
+is of the form: ``'sim_gpioX'`` where X is the offset of the line. Inside each
+group there are two attibutes:
+
+ ``pull`` - allows to read and set the current simulated pull setting for
+ every line, when writing the value must be one of: ``'pull-up'``,
+ ``'pull-down'``
+
+ ``value`` - allows to read the current value of the line which may be
+ different from the pull if the line is being driven from
+ user-space

+================================================
+HiSilicon PCIe Performance Monitoring Unit (PMU)
+================================================
+
+On Hip09, HiSilicon PCIe Performance Monitoring Unit (PMU) could monitor
+bandwidth, latency, bus utilization and buffer occupancy data of PCIe.
+
+Each PCIe Core has a PMU to monitor multi Root Ports of this PCIe Core and
+all Endpoints downstream these Root Ports.
+
+
+HiSilicon PCIe PMU driver
+=========================
+
+The PCIe PMU driver registers a perf PMU with the name of its sicl-id and PCIe
+Core id.::
+
+ /sys/bus/event_source/hisi_pcie<sicl>_<core>
+
+PMU driver provides description of available events and filter options in sysfs,
+see /sys/bus/event_source/devices/hisi_pcie<sicl>_<core>.
+
+The "format" directory describes all formats of the config (events) and config1
+(filter options) fields of the perf_event_attr structure. The "events" directory
+describes all documented events shown in perf list.
+
+The "identifier" sysfs file allows users to identify the version of the
+PMU hardware device.
+
+The "bus" sysfs file allows users to get the bus number of Root Ports
+monitored by PMU.
+
+Example usage of perf::
+
+ $# perf list
+ hisi_pcie0_0/rx_mwr_latency/ [kernel PMU event]
+ hisi_pcie0_0/rx_mwr_cnt/ [kernel PMU event]
+ ------------------------------------------

+ $# perf stat -e hisi_pcie0_0/rx_mwr_cnt/
+ $# perf stat -g -e hisi_pcie0_0/rx_mwr_latency/ -e hisi_pcie0_0/rx_mwr_cnt/
+
+The current driver does not support sampling. So "perf record" is unsupported.
+Also attach to a task is unsupported for PCIe PMU.
+
+Filter options
+--------------
+
+1. Target filter
+PMU could only monitor the performance of traffic downstream target Root Ports
+or downstream target Endpoint. PCIe PMU driver support "port" and "bdf"
+interfaces for users, and these two interfaces aren't supported at the same
+time.
+
+-port
+"port" filter can be used in all PCIe PMU events, target Root Port can be
+selected by configuring the 16-bits-bitmap "port". Multi ports can be selected
+for AP-layer-events, and only one port can be selected for TL/DL-layer-events.
+
+For example, if target Root Port is 0000:00:00.0 (x8 lanes), bit0 of bitmap
+should be set, port=0x1; if target Root Port is 0000:00:04.0 (x4 lanes),
+bit8 is set, port=0x100; if these two Root Ports are both monitored, port=0x101.
+
+Example usage of perf::
+
+ $# perf stat -e hisi_pcie0_0/rx_mwr_latency,port=0x1/ sleep 5
+
+-bdf
+
+"bdf" filter can only be used in bandwidth events, target Endpoint is selected
+by configuring BDF to "bdf". Counter only counts the bandwidth of message
+requested by target Endpoint.
+
+For example, "bdf=0x3900" means BDF of target Endpoint is 0000:39:00.0.
+
+Example usage of perf::
+
+ $# perf stat -e hisi_pcie0_0/rx_mrd_flux,bdf=0x3900/ sleep 5
+
+2. Trigger filter
+Event statistics start when the first time TLP length is greater/smaller
+than trigger condition. You can set the trigger condition by writing "trig_len",
+and set the trigger mode by writing "trig_mode". This filter can only be used
+in bandwidth events.
+
+For example, "trig_len=4" means trigger condition is 2^4 DW, "trig_mode=0"
+means statistics start when TLP length > trigger condition, "trig_mode=1"
+means start when TLP length < condition.
+
+Example usage of perf::
+
+ $# perf stat -e hisi_pcie0_0/rx_mrd_flux,trig_len=0x4,trig_mode=1/ sleep 5
+
+3. Threshold filter
+Counter counts when TLP length within the specified range. You can set the
+threshold by writing "thr_len", and set the threshold mode by writing
+"thr_mode". This filter can only be used in bandwidth events.
+
+For example, "thr_len=4" means threshold is 2^4 DW, "thr_mode=0" means
+counter counts when TLP length >= threshold, and "thr_mode=1" means counts
+when TLP length < threshold.
+
+Example usage of perf::
+
+ $# perf stat -e hisi_pcie0_0/rx_mrd_flux,thr_len=0x4,thr_mode=1/ sleep 5

+``amd-pstate`` CPU Performance Scaling Driver
+===============================================

+
+:Author: Huang Rui <ray.huang@amd.com>
+
+
+Introduction
+===================
+
+``amd-pstate`` is the AMD CPU performance scaling driver that introduces a
+new CPU frequency control mechanism on modern AMD APU and CPU series in
+Linux kernel. The new mechanism is based on Collaborative Processor
+Performance Control (CPPC) which provides finer grain frequency management
+than legacy ACPI hardware P-States. Current AMD CPU/APU platforms are using
+the ACPI P-states driver to manage CPU frequency and clocks with switching
+only in 3 P-states. CPPC replaces the ACPI P-states controls, allows a
+flexible, low-latency interface for the Linux kernel to directly
+communicate the performance hints to hardware.
+
+``amd-pstate`` leverages the Linux kernel governors such as ``schedutil``,
+``ondemand``, etc. to manage the performance hints which are provided by
+CPPC hardware functionality that internally follows the hardware
+specification (for details refer to AMD64 Architecture Programmer's Manual
+Volume 2: System Programming [1]_). Currently ``amd-pstate`` supports basic
+frequency control function according to kernel governors on some of the
+Zen2 and Zen3 processors, and we will implement more AMD specific functions
+in future after we verify them on the hardware and SBIOS.
+
+
+AMD CPPC Overview
+=======================
+
+Collaborative Processor Performance Control (CPPC) interface enumerates a
+continuous, abstract, and unit-less performance value in a scale that is
+not tied to a specific performance state / frequency. This is an ACPI
+standard [2]_ which software can specify application performance goals and
+hints as a relative target to the infrastructure limits. AMD processors
+provides the low latency register model (MSR) instead of AML code
+interpreter for performance adjustments. ``amd-pstate`` will initialize a
+``struct cpufreq_driver`` instance ``amd_pstate_driver`` with the callbacks
+to manage each performance update behavior. ::

+ AMD P-States Performance Scale
+
+
+.. _perf_cap:
+
+AMD CPPC Performance Capability
+--------------------------------
+
+Highest Performance (RO)
+.........................
+
+It is the absolute maximum performance an individual processor may reach,
+assuming ideal conditions. This performance level may not be sustainable
+for long durations and may only be achievable if other platform components
+are in a specific state; for example, it may require other processors be in
+an idle state. This would be equivalent to the highest frequencies
+supported by the processor.
+
+Nominal (Guaranteed) Performance (RO)
+......................................
+
+It is the maximum sustained performance level of the processor, assuming
+ideal operating conditions. In absence of an external constraint (power,
+thermal, etc.) this is the performance level the processor is expected to
+be able to maintain continuously. All cores/processors are expected to be
+able to sustain their nominal performance state simultaneously.
+
+Lowest non-linear Performance (RO)
+...................................
+
+It is the lowest performance level at which nonlinear power savings are
+achieved, for example, due to the combined effects of voltage and frequency
+scaling. Above this threshold, lower performance levels should be generally
+more energy efficient than higher performance levels. This register
+effectively conveys the most efficient performance level to ``amd-pstate``.
+
+Lowest Performance (RO)
+........................
+
+It is the absolute lowest performance level of the processor. Selecting a
+performance level lower than the lowest nonlinear performance level may
+cause an efficiency penalty but should reduce the instantaneous power
+consumption of the processor.
+
+AMD CPPC Performance Control
+------------------------------
+
+``amd-pstate`` passes performance goals through these registers. The
+register drives the behavior of the desired performance target.
+
+Minimum requested performance (RW)
+...................................
+
+``amd-pstate`` specifies the minimum allowed performance level.
+
+Maximum requested performance (RW)
+...................................
+
+``amd-pstate`` specifies a limit the maximum performance that is expected
+to be supplied by the hardware.
+
+Desired performance target (RW)
+...................................
+
+``amd-pstate`` specifies a desired target in the CPPC performance scale as
+a relative number. This can be expressed as percentage of nominal
+performance (infrastructure max). Below the nominal sustained performance
+level, desired performance expresses the average performance level of the
+processor subject to hardware. Above the nominal performance level,
+processor must provide at least nominal performance requested and go higher
+if current operating conditions allow.
+
+Energy Performance Preference (EPP) (RW)
+.........................................
+
+Provides a hint to the hardware if software wants to bias toward performance
+(0x0) or energy efficiency (0xff).
+
+
+Key Governors Support
+=======================
+
+``amd-pstate`` can be used with all the (generic) scaling governors listed
+by the ``scaling_available_governors`` policy attribute in ``sysfs``. Then,
+it is responsible for the configuration of policy objects corresponding to
+CPUs and provides the ``CPUFreq`` core (and the scaling governors attached
+to the policy objects) with accurate information on the maximum and minimum
+operating frequencies supported by the hardware. Users can check the
+``scaling_cur_freq`` information comes from the ``CPUFreq`` core.
+
+``amd-pstate`` mainly supports ``schedutil`` and ``ondemand`` for dynamic
+frequency control. It is to fine tune the processor configuration on
+``amd-pstate`` to the ``schedutil`` with CPU CFS scheduler. ``amd-pstate``
+registers adjust_perf callback to implement the CPPC similar performance
+update behavior. It is initialized by ``sugov_start`` and then populate the
+CPU's update_util_data pointer to assign ``sugov_update_single_perf`` as
+the utilization update callback function in CPU scheduler. CPU scheduler
+will call ``cpufreq_update_util`` and assign the target performance
+according to the ``struct sugov_cpu`` that utilization update belongs to.
+Then ``amd-pstate`` updates the desired performance according to the CPU
+scheduler assigned.
+
+
+Processor Support
+=======================
+
+The ``amd-pstate`` initialization will fail if the _CPC in ACPI SBIOS is
+not existed at the detected processor, and it uses ``acpi_cpc_valid`` to
+check the _CPC existence. All Zen based processors support legacy ACPI
+hardware P-States function, so while the ``amd-pstate`` fails to be
+initialized, the kernel will fall back to initialize ``acpi-cpufreq``
+driver.
+
+There are two types of hardware implementations for ``amd-pstate``: one is
+`Full MSR Support <perf_cap_>`_ and another is `Shared Memory Support
+<perf_cap_>`_. It can use :c:macro:`X86_FEATURE_CPPC` feature flag (for
+details refer to Processor Programming Reference (PPR) for AMD Family
+19h Model 51h, Revision A1 Processors [3]_) to indicate the different
+types. ``amd-pstate`` is to register different ``static_call`` instances
+for different hardware implementations.
+
+Currently, some of Zen2 and Zen3 processors support ``amd-pstate``. In the
+future, it will be supported on more and more AMD processors.
+
+Full MSR Support
+-----------------
+
+Some new Zen3 processors such as Cezanne provide the MSR registers directly
+while the :c:macro:`X86_FEATURE_CPPC` CPU feature flag is set.
+``amd-pstate`` can handle the MSR register to implement the fast switch
+function in ``CPUFreq`` that can shrink latency of frequency control on the
+interrupt context. The functions with ``pstate_xxx`` prefix represent the
+operations of MSR registers.
+
+Shared Memory Support
+----------------------
+
+If :c:macro:`X86_FEATURE_CPPC` CPU feature flag is not set, that means the
+processor supports shared memory solution. In this case, ``amd-pstate``
+uses the ``cppc_acpi`` helper methods to implement the callback functions
+that defined on ``static_call``. The functions with ``cppc_xxx`` prefix
+represent the operations of acpi cppc helpers for shared memory solution.
+
+
+AMD P-States and ACPI hardware P-States always can be supported in one
+processor. But AMD P-States has the higher priority and if it is enabled
+with :c:macro:`MSR_AMD_CPPC_ENABLE` or ``cppc_set_enable``, it will respond
+to the request from AMD P-States.
+
+
+User Space Interface in ``sysfs``
+==================================
+
+``amd-pstate`` exposes several global attributes (files) in ``sysfs`` to
+control its functionality at the system level. They located in the
+``/sys/devices/system/cpu/cpufreq/policyX/`` directory and affect all CPUs. ::
+
+ root@hr-test1:/home/ray# ls /sys/devices/system/cpu/cpufreq/policy0/*amd*
+ /sys/devices/system/cpu/cpufreq/policy0/amd_pstate_highest_perf
+ /sys/devices/system/cpu/cpufreq/policy0/amd_pstate_lowest_nonlinear_freq
+ /sys/devices/system/cpu/cpufreq/policy0/amd_pstate_max_freq
+
+
+``amd_pstate_highest_perf / amd_pstate_max_freq``
+
+Maximum CPPC performance and CPU frequency that the driver is allowed to
+set in percent of the maximum supported CPPC performance level (the highest
+performance supported in `AMD CPPC Performance Capability <perf_cap_>`_).
+In some of ASICs, the highest CPPC performance is not the one in the _CPC
+table, so we need to expose it to sysfs. If boost is not active but
+supported, this maximum frequency will be larger than the one in
+``cpuinfo``.
+This attribute is read-only.
+
+``amd_pstate_lowest_nonlinear_freq``
+
+The lowest non-linear CPPC CPU frequency that the driver is allowed to set
+in percent of the maximum supported CPPC performance level (Please see the
+lowest non-linear performance in `AMD CPPC Performance Capability
+<perf_cap_>`_).
+This attribute is read-only.
+
+For other performance and frequency values, we can read them back from
+``/sys/devices/system/cpu/cpuX/acpi_cppc/``, see :ref:`cppc_sysfs`.
+
+
+``amd-pstate`` vs ``acpi-cpufreq``
+======================================
+
+On majority of AMD platforms supported by ``acpi-cpufreq``, the ACPI tables
+provided by the platform firmware used for CPU performance scaling, but
+only provides 3 P-states on AMD processors.
+However, on modern AMD APU and CPU series, it provides the collaborative
+processor performance control according to ACPI protocol and customize this
+for AMD platforms. That is fine-grain and continuous frequency range
+instead of the legacy hardware P-states. ``amd-pstate`` is the kernel
+module which supports the new AMD P-States mechanism on most of future AMD
+platforms. The AMD P-States mechanism will be the more performance and energy
+efficiency frequency management method on AMD processors.
+
+Kernel Module Options for ``amd-pstate``
+=========================================
+
+``shared_mem``
+Use a module param (shared_mem) to enable related processors manually with
+**amd_pstate.shared_mem=1**.
+Due to the performance issue on the processors with `Shared Memory Support
+<perf_cap_>`_, so we disable it for the moment and will enable this by default
+once we address performance issue on this solution.
+
+The way to check whether current processor is `Full MSR Support <perf_cap_>`_
+or `Shared Memory Support <perf_cap_>`_ : ::
+
+ ray@hr-test1:~$ lscpu | grep cppc
+ Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm constant_tsc rep_good nopl nonstop_tsc cpuid extd_apicid aperfmperf rapl pni pclmulqdq monitor ssse3 fma cx16 sse4_1 sse4_2 x2apic movbe popcnt aes xsave avx f16c rdrand lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs skinit wdt tce topoext perfctr_core perfctr_nb bpext perfctr_llc mwaitx cpb cat_l3 cdp_l3 hw_pstate ssbd mba ibrs ibpb stibp vmmcall fsgsbase bmi1 avx2 smep bmi2 erms invpcid cqm rdt_a rdseed adx smap clflushopt clwb sha_ni xsaveopt xsavec xgetbv1 xsaves cqm_llc cqm_occup_llc cqm_mbm_total cqm_mbm_local clzero irperf xsaveerptr rdpru wbnoinvd cppc arat npt lbrv svm_lock nrip_save tsc_scale vmcb_clean flushbyasid decodeassists pausefilter pfthreshold avic v_vmsave_vmload vgif v_spec_ctrl umip pku ospke vaes vpclmulqdq rdpid overflow_recov succor smca fsrm
+
+If CPU Flags have cppc, then this processor supports `Full MSR Support
+<perf_cap_>`_. Otherwise it supports `Shared Memory Support <perf_cap_>`_.
+
+
+``cpupower`` tool support for ``amd-pstate``
+===============================================
+
+``amd-pstate`` is supported on ``cpupower`` tool that can be used to dump the frequency
+information. And it is in progress to support more and more operations for new
+``amd-pstate`` module with this tool. ::
+
+ root@hr-test1:/home/ray# cpupower frequency-info

+ AMD PSTATE Lowest Performance: 15. Lowest Frequency: 400 MHz.
+
+
+Diagnostics and Tuning
+=======================
+
+Trace Events
+--------------
+
+There are two static trace events that can be used for ``amd-pstate``
+diagnostics. One of them is the cpu_frequency trace event generally used
+by ``CPUFreq``, and the other one is the ``amd_pstate_perf`` trace event
+specific to ``amd-pstate``. The following sequence of shell commands can
+be used to enable them and see their output (if the kernel is generally
+configured to support event tracing). ::
+

+
+Important note on ARC processors configurability
+################################################
+
+ARC processors are highly configurable and several configurable options
+are supported in Linux. Some options are transparent to software
+(i.e cache geometries, some can be detected at runtime and configured
+and used accordingly, while some need to be explicitly selected or configured
+in the kernel's configuration utility (AKA "make menuconfig").
+
+However not all configurable options are supported when an ARC processor
+is to run Linux. SoC design teams should refer to "Appendix E:
+Configuration for ARC Linux" in the ARC HS Databook for configurability
+guidelines.
+
+Following these guidelines and selecting valid configuration options
+up front is critical to help prevent any unwanted issues during
+SoC bringup and software development in general.
+
+Building the Linux kernel for ARC processors
+############################################
+
+The process of kernel building for ARC processors is the same as for any other
+architecture and could be done in 2 ways:
+
+- Cross-compilation: process of compiling for ARC targets on a development
+ host with a different processor architecture (generally x86_64/amd64).
+- Native compilation: process of compiling for ARC on a ARC platform
+ (hardware board or a simulator like QEMU) with complete development environment
+ (GNU toolchain, dtc, make etc) installed on the platform.
+
+In both cases, up-to-date GNU toolchain for ARC for the host is needed.
+Synopsys offers prebuilt toolchain releases which can be used for this purpose,
+available from:
+
+- Synopsys GNU toolchain releases:
+ `<https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases>`_
+
+- Linux kernel compilers collection:
+ `<https://mirrors.edge.kernel.org/pub/tools/crosstool>`_
+
+- Bootlin's toolchain collection: `<https://toolchains.bootlin.com>`_
+
+Once the toolchain is installed in the system, make sure its "bin" folder
+is added in your ``PATH`` environment variable. Then set ``ARCH=arc`` &
+``CROSS_COMPILE=arc-linux`` (or whatever matches installed ARC toolchain prefix)
+and then as usual ``make defconfig && make``.
+
+This will produce "vmlinux" file in the root of the kernel source tree
+usable for loading on the target system via JTAG.
+If you need to get an image usable with U-Boot bootloader,
+type ``make uImage`` and ``uImage`` will be produced in ``arch/arc/boot``
+folder.

Perf Event Attributes

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.

-Queue sysfs files
-=================
-
-This text file will detail the queue files that are located in the sysfs tree
-for each block device. Note that stacked devices typically do not export
-any settings, since their queue merely functions as a remapping target.
-These files are the ones found in the /sys/block/xxx/queue/ directory.
-
-Files denoted with a RO postfix are readonly and the RW postfix means
-read-write.
-
-add_random (RW)
----------------
-This file allows to turn off the disk entropy contribution. Default
-value of this file is '1'(on).
-
-chunk_sectors (RO)
-------------------
-This has different meaning depending on the type of the block device.
-For a RAID device (dm-raid), chunk_sectors indicates the size in 512B sectors
-of the RAID volume stripe segment. For a zoned block device, either host-aware
-or host-managed, chunk_sectors indicates the size in 512B sectors of the zones
-of the device, with the eventual exception of the last zone of the device which
-may be smaller.
-
-dax (RO)
---------
-This file indicates whether the device supports Direct Access (DAX),
-used by CPU-addressable storage to bypass the pagecache. It shows '1'
-if true, '0' if not.
-
-discard_granularity (RO)
-------------------------
-This shows the size of internal allocation of the device in bytes, if
-reported by the device. A value of '0' means device does not support
-the discard functionality.
-
-discard_max_hw_bytes (RO)
--------------------------
-Devices that support discard functionality may have internal limits on
-the number of bytes that can be trimmed or unmapped in a single operation.
-The `discard_max_hw_bytes` parameter is set by the device driver to the
-maximum number of bytes that can be discarded in a single operation.
-Discard requests issued to the device must not exceed this limit.
-A `discard_max_hw_bytes` value of 0 means that the device does not support
-discard functionality.
-
-discard_max_bytes (RW)
-----------------------
-While discard_max_hw_bytes is the hardware limit for the device, this
-setting is the software limit. Some devices exhibit large latencies when
-large discards are issued, setting this value lower will make Linux issue
-smaller discards and potentially help reduce latencies induced by large
-discard operations.
-
-discard_zeroes_data (RO)
-------------------------
-Obsolete. Always zero.
-
-fua (RO)
---------
-Whether or not the block driver supports the FUA flag for write requests.
-FUA stands for Force Unit Access. If the FUA flag is set that means that
-write requests must bypass the volatile cache of the storage device.
-
-hw_sector_size (RO)
--------------------
-This is the hardware sector size of the device, in bytes.
-
-io_poll (RW)
-------------
-When read, this file shows whether polling is enabled (1) or disabled
-(0). Writing '0' to this file will disable polling for this device.
-Writing any non-zero value will enable this feature.
-
-io_poll_delay (RW)
-------------------
-If polling is enabled, this controls what kind of polling will be
-performed. It defaults to -1, which is classic polling. In this mode,
-the CPU will repeatedly ask for completions without giving up any time.
-If set to 0, a hybrid polling mode is used, where the kernel will attempt
-to make an educated guess at when the IO will complete. Based on this
-guess, the kernel will put the process issuing IO to sleep for an amount
-of time, before entering a classic poll loop. This mode might be a
-little slower than pure classic polling, but it will be more efficient.
-If set to a value larger than 0, the kernel will put the process issuing
-IO to sleep for this amount of microseconds before entering classic
-polling.
-
-io_timeout (RW)
----------------
-io_timeout is the request timeout in milliseconds. If a request does not
-complete in this time then the block driver timeout handler is invoked.
-That timeout handler can decide to retry the request, to fail it or to start
-a device recovery strategy.
-
-iostats (RW)
--------------
-This file is used to control (on/off) the iostats accounting of the
-disk.
-
-logical_block_size (RO)
------------------------
-This is the logical block size of the device, in bytes.
-
-max_discard_segments (RO)
--------------------------
-The maximum number of DMA scatter/gather entries in a discard request.
-
-max_hw_sectors_kb (RO)
-----------------------
-This is the maximum number of kilobytes supported in a single data transfer.
-
-max_integrity_segments (RO)
----------------------------
-Maximum number of elements in a DMA scatter/gather list with integrity
-data that will be submitted by the block layer core to the associated
-block driver.
-
-max_active_zones (RO)
----------------------
-For zoned block devices (zoned attribute indicating "host-managed" or
-"host-aware"), the sum of zones belonging to any of the zone states:
-EXPLICIT OPEN, IMPLICIT OPEN or CLOSED, is limited by this value.
-If this value is 0, there is no limit.
-
-If the host attempts to exceed this limit, the driver should report this error
-with BLK_STS_ZONE_ACTIVE_RESOURCE, which user space may see as the EOVERFLOW
-errno.
-
-max_open_zones (RO)
--------------------
-For zoned block devices (zoned attribute indicating "host-managed" or
-"host-aware"), the sum of zones belonging to any of the zone states:
-EXPLICIT OPEN or IMPLICIT OPEN, is limited by this value.
-If this value is 0, there is no limit.
-
-If the host attempts to exceed this limit, the driver should report this error
-with BLK_STS_ZONE_OPEN_RESOURCE, which user space may see as the ETOOMANYREFS
-errno.
-
-max_sectors_kb (RW)
--------------------
-This is the maximum number of kilobytes that the block layer will allow
-for a filesystem request. Must be smaller than or equal to the maximum
-size allowed by the hardware.
-
-max_segments (RO)
------------------
-Maximum number of elements in a DMA scatter/gather list that is submitted
-to the associated block driver.
-
-max_segment_size (RO)
----------------------
-Maximum size in bytes of a single element in a DMA scatter/gather list.
-
-minimum_io_size (RO)
---------------------
-This is the smallest preferred IO size reported by the device.
-
-nomerges (RW)
--------------
-This enables the user to disable the lookup logic involved with IO
-merging requests in the block layer. By default (0) all merges are
-enabled. When set to 1 only simple one-hit merges will be tried. When
-set to 2 no merge algorithms will be tried (including one-hit or more
-complex tree/hash lookups).
-
-nr_requests (RW)
-----------------
-This controls how many requests may be allocated in the block layer for
-read or write requests. Note that the total allocated number may be twice
-this amount, since it applies only to reads or writes (not the accumulated
-sum).
-
-To avoid priority inversion through request starvation, a request
-queue maintains a separate request pool per each cgroup when
-CONFIG_BLK_CGROUP is enabled, and this parameter applies to each such
-per-block-cgroup request pool. IOW, if there are N block cgroups,
-each request queue may have up to N request pools, each independently
-regulated by nr_requests.
-
-nr_zones (RO)
--------------
-For zoned block devices (zoned attribute indicating "host-managed" or
-"host-aware"), this indicates the total number of zones of the device.
-This is always 0 for regular block devices.
-
-optimal_io_size (RO)
---------------------
-This is the optimal IO size reported by the device.
-
-physical_block_size (RO)
-------------------------
-This is the physical block size of device, in bytes.
-
-read_ahead_kb (RW)
-------------------
-Maximum number of kilobytes to read-ahead for filesystems on this block
-device.
-
-rotational (RW)
----------------
-This file is used to stat if the device is of rotational type or
-non-rotational type.
-
-rq_affinity (RW)
-----------------
-If this option is '1', the block layer will migrate request completions to the
-cpu "group" that originally submitted the request. For some workloads this
-provides a significant reduction in CPU cycles due to caching effects.
-
-For storage configurations that need to maximize distribution of completion
-processing setting this option to '2' forces the completion to run on the
-requesting cpu (bypassing the "group" aggregation logic).
-
-scheduler (RW)
---------------
-When read, this file will display the current and available IO schedulers
-for this block device. The currently active IO scheduler will be enclosed
-in [] brackets. Writing an IO scheduler name to this file will switch
-control of this block device to that new IO scheduler. Note that writing
-an IO scheduler name to this file will attempt to load that IO scheduler
-module, if it isn't already present in the system.
-
-write_cache (RW)
-----------------
-When read, this file will display whether the device has write back
-caching enabled or not. It will return "write back" for the former
-case, and "write through" for the latter. Writing to this file can
-change the kernels view of the device, but it doesn't alter the
-device state. This means that it might not be safe to toggle the
-setting from "write back" to "write through", since that will also
-eliminate cache flushes issued by the kernel.
-
-write_same_max_bytes (RO)
--------------------------
-This is the number of bytes the device can write in a single write-same
-command. A value of '0' means write-same is not supported by this
-device.
-
-wbt_lat_usec (RW)
------------------
-If the device is registered for writeback throttling, then this file shows
-the target minimum read latency. If this latency is exceeded in a given
-window of time (see wb_window_usec), then the writeback throttling will start
-scaling back writes. Writing a value of '0' to this file disables the
-feature. Writing a value of '-1' to this file resets the value to the
-default setting.
-
-throttle_sample_time (RW)
--------------------------
-This is the time window that blk-throttle samples data, in millisecond.
-blk-throttle makes decision based on the samplings. Lower time means cgroups
-have more smooth throughput, but higher CPU overhead. This exists only when
-CONFIG_BLK_DEV_THROTTLING_LOW is enabled.
-
-write_zeroes_max_bytes (RO)
----------------------------
-For block drivers that support REQ_OP_WRITE_ZEROES, the maximum number of
-bytes that can be zeroed at once. The value 0 means that REQ_OP_WRITE_ZEROES
-is not supported.
-
-zone_append_max_bytes (RO)
---------------------------
-This is the maximum number of bytes that can be written to a sequential
-zone of a zoned block device using a zone append write operation
-(REQ_OP_ZONE_APPEND). This value is always 0 for regular block devices.
-
-zoned (RO)
-----------
-This indicates if the device is a zoned block device and the zone model of the
-device if it is indeed zoned. The possible values indicated by zoned are
-"none" for regular block devices and "host-aware" or "host-managed" for zoned
-block devices. The characteristics of host-aware and host-managed zoned block
-devices are described in the ZBC (Zoned Block Commands) and ZAC
-(Zoned Device ATA Command Set) standards. These standards also define the
-"drive-managed" zone model. However, since drive-managed zoned block devices
-do not support zone commands, they will be treated as regular block devices
-and zoned will report "none".
-
-zone_write_granularity (RO)
----------------------------
-This indicates the alignment constraint, in bytes, for write operations in
-sequential zones of zoned block devices (devices with a zoned attributed
-that reports "host-managed" or "host-aware"). This value is always 0 for
-regular block devices.
-
-independent_access_ranges (RO)
-------------------------------
-
-The presence of this sub-directory of the /sys/block/xxx/queue/ directory
-indicates that the device is capable of executing requests targeting
-different sector ranges in parallel. For instance, single LUN multi-actuator
-hard-disks will have an independent_access_ranges directory if the device
-correctly advertizes the sector ranges of its actuators.
-
-The independent_access_ranges directory contains one directory per access
-range, with each range described using the sector (RO) attribute file to
-indicate the first sector of the range and the nr_sectors (RO) attribute file
-to indicate the total number of sectors in the range starting from the first
-sector of the range. For example, a dual-actuator hard-disk will have the
-following independent_access_ranges entries.::
-
- $ tree /sys/block/<device>/queue/independent_access_ranges/
- /sys/block/<device>/queue/independent_access_ranges/
- |-- 0
- | |-- nr_sectors
- | `-- sector
- `-- 1
- |-- nr_sectors
- `-- sector
-
-The sector and nr_sectors attributes use 512B sector unit, regardless of
-the actual block size of the device. Independent access ranges do not
-overlap and include all sectors within the device capacity. The access
-ranges are numbered in increasing order of the range start sector,
-that is, the sector attribute of range 0 always has the value 0.

+===================
+Classic BPF vs eBPF
+===================
+
+eBPF is designed to be JITed with one to one mapping, which can also open up
+the possibility for GCC/LLVM compilers to generate optimized eBPF code through
+an eBPF backend that performs almost as fast as natively compiled code.
+
+Some core changes of the eBPF format from classic BPF:
+
+- Number of registers increase from 2 to 10:
+
+ The old format had two registers A and X, and a hidden frame pointer. The
+ new layout extends this to be 10 internal registers and a read-only frame
+ pointer. Since 64-bit CPUs are passing arguments to functions via registers
+ the number of args from eBPF program to in-kernel function is restricted
+ to 5 and one register is used to accept return value from an in-kernel
+ function. Natively, x86_64 passes first 6 arguments in registers, aarch64/
+ sparcv9/mips64 have 7 - 8 registers for arguments; x86_64 has 6 callee saved
+ registers, and aarch64/sparcv9/mips64 have 11 or more callee saved registers.
+
+ Thus, all eBPF registers map one to one to HW registers on x86_64, aarch64,
+ etc, and eBPF calling convention maps directly to ABIs used by the kernel on
+ 64-bit architectures.
+
+ On 32-bit architectures JIT may map programs that use only 32-bit arithmetic
+ and may let more complex programs to be interpreted.
+
+ R0 - R5 are scratch registers and eBPF program needs spill/fill them if
+ necessary across calls. Note that there is only one eBPF program (== one
+ eBPF main routine) and it cannot call other eBPF functions, it can only
+ call predefined in-kernel functions, though.
+
+- Register width increases from 32-bit to 64-bit:
+
+ Still, the semantics of the original 32-bit ALU operations are preserved
+ via 32-bit subregisters. All eBPF registers are 64-bit with 32-bit lower
+ subregisters that zero-extend into 64-bit if they are being written to.
+ That behavior maps directly to x86_64 and arm64 subregister definition, but
+ makes other JITs more difficult.
+
+ 32-bit architectures run 64-bit eBPF programs via interpreter.
+ Their JITs may convert BPF programs that only use 32-bit subregisters into
+ native instruction set and let the rest being interpreted.
+
+ Operation is 64-bit, because on 64-bit architectures, pointers are also
+ 64-bit wide, and we want to pass 64-bit values in/out of kernel functions,
+ so 32-bit eBPF registers would otherwise require to define register-pair
+ ABI, thus, there won't be able to use a direct eBPF register to HW register
+ mapping and JIT would need to do combine/split/move operations for every
+ register in and out of the function, which is complex, bug prone and slow.
+ Another reason is the use of atomic 64-bit counters.
+
+- Conditional jt/jf targets replaced with jt/fall-through:
+
+ While the original design has constructs such as ``if (cond) jump_true;
+ else jump_false;``, they are being replaced into alternative constructs like
+ ``if (cond) jump_true; /* else fall-through */``.
+
+- Introduces bpf_call insn and register passing convention for zero overhead
+ calls from/to other kernel functions:
+
+ Before an in-kernel function call, the eBPF program needs to
+ place function arguments into R1 to R5 registers to satisfy calling
+ convention, then the interpreter will take them from registers and pass
+ to in-kernel function. If R1 - R5 registers are mapped to CPU registers
+ that are used for argument passing on given architecture, the JIT compiler
+ doesn't need to emit extra moves. Function arguments will be in the correct
+ registers and BPF_CALL instruction will be JITed as single 'call' HW
+ instruction. This calling convention was picked to cover common call
+ situations without performance penalty.
+
+ After an in-kernel function call, R1 - R5 are reset to unreadable and R0 has
+ a return value of the function. Since R6 - R9 are callee saved, their state
+ is preserved across the call.
+
+ For example, consider three C functions::
+
+ u64 f1() { return (*_f2)(1); }
+ u64 f2(u64 a) { return f3(a + 1, a); }
+ u64 f3(u64 a, u64 b) { return a - b; }
+
+ GCC can compile f1, f3 into x86_64::
+
+ f1:
+ movl $1, %edi
+ movq _f2(%rip), %rax
+ jmp *%rax
+ f3:
+ movq %rdi, %rax
+ subq %rsi, %rax
+ ret
+
+ Function f2 in eBPF may look like::
+
+ f2:
+ bpf_mov R2, R1
+ bpf_add R1, 1
+ bpf_call f3
+ bpf_exit
+
+ If f2 is JITed and the pointer stored to ``_f2``. The calls f1 -> f2 -> f3 and
+ returns will be seamless. Without JIT, __bpf_prog_run() interpreter needs to
+ be used to call into f2.
+
+ For practical reasons all eBPF programs have only one argument 'ctx' which is
+ already placed into R1 (e.g. on __bpf_prog_run() startup) and the programs
+ can call kernel functions with up to 5 arguments. Calls with 6 or more arguments
+ are currently not supported, but these restrictions can be lifted if necessary
+ in the future.
+
+ On 64-bit architectures all register map to HW registers one to one. For
+ example, x86_64 JIT compiler can map them as ...
+
+ ::
+
+ R0 - rax
+ R1 - rdi
+ R2 - rsi
+ R3 - rdx
+ R4 - rcx
+ R5 - r8
+ R6 - rbx
+ R7 - r13
+ R8 - r14
+ R9 - r15
+ R10 - rbp
+
+ ... since x86_64 ABI mandates rdi, rsi, rdx, rcx, r8, r9 for argument passing
+ and rbx, r12 - r15 are callee saved.
+
+ Then the following eBPF pseudo-program::
+
+ bpf_mov R6, R1 /* save ctx */
+ bpf_mov R2, 2
+ bpf_mov R3, 3
+ bpf_mov R4, 4
+ bpf_mov R5, 5
+ bpf_call foo
+ bpf_mov R7, R0 /* save foo() return value */
+ bpf_mov R1, R6 /* restore ctx for next call */
+ bpf_mov R2, 6
+ bpf_mov R3, 7
+ bpf_mov R4, 8
+ bpf_mov R5, 9
+ bpf_call bar
+ bpf_add R0, R7
+ bpf_exit
+
+ After JIT to x86_64 may look like::
+
+ push %rbp
+ mov %rsp,%rbp
+ sub $0x228,%rsp
+ mov %rbx,-0x228(%rbp)
+ mov %r13,-0x220(%rbp)
+ mov %rdi,%rbx
+ mov $0x2,%esi
+ mov $0x3,%edx
+ mov $0x4,%ecx
+ mov $0x5,%r8d
+ callq foo
+ mov %rax,%r13
+ mov %rbx,%rdi
+ mov $0x6,%esi
+ mov $0x7,%edx
+ mov $0x8,%ecx
+ mov $0x9,%r8d
+ callq bar
+ add %r13,%rax
+ mov -0x228(%rbp),%rbx
+ mov -0x220(%rbp),%r13
+ leaveq
+ retq
+
+ Which is in this example equivalent in C to::
+
+ u64 bpf_filter(u64 ctx)
+ {
+ return foo(ctx, 2, 3, 4, 5) + bar(ctx, 6, 7, 8, 9);
+ }
+
+ In-kernel functions foo() and bar() with prototype: u64 (*)(u64 arg1, u64
+ arg2, u64 arg3, u64 arg4, u64 arg5); will receive arguments in proper
+ registers and place their return value into ``%rax`` which is R0 in eBPF.
+ Prologue and epilogue are emitted by JIT and are implicit in the
+ interpreter. R0-R5 are scratch registers, so eBPF program needs to preserve
+ them across the calls as defined by calling convention.
+
+ For example the following program is invalid::
+
+ bpf_mov R1, 1
+ bpf_call foo
+ bpf_mov R0, R1
+ bpf_exit
+
+ After the call the registers R1-R5 contain junk values and cannot be read.
+ An in-kernel verifier.rst is used to validate eBPF programs.
+
+Also in the new design, eBPF is limited to 4096 insns, which means that any
+program will terminate quickly and will only call a fixed number of kernel
+functions. Original BPF and eBPF are two operand instructions,
+which helps to do one-to-one mapping between eBPF insn and x86 insn during JIT.
+
+The input context pointer for invoking the interpreter function is generic,
+its content is defined by a specific use case. For seccomp register R1 points
+to seccomp_data, for converted BPF filters R1 points to a skb.
+
+A program, that is translated internally consists of the following elements::
+
+ op:16, jt:8, jf:8, k:32 ==> op:8, dst_reg:4, src_reg:4, off:16, imm:32
+
+So far 87 eBPF instructions were implemented. 8-bit 'op' opcode field
+has room for new instructions. Some of them may use 16/24/32 byte encoding. New
+instructions must be multiple of 8 bytes to preserve backward compatibility.
+
+eBPF is a general purpose RISC instruction set. Not every register and
+every instruction are used during translation from original BPF to eBPF.
+For example, socket filters are not using ``exclusive add`` instruction, but
+tracing filters may do to maintain counters of events, for example. Register R9
+is not used by socket filters either, but more complex filters may be running
+out of registers and would have to resort to spill/fill to stack.
+
+eBPF can be used as a generic assembler for last step performance
+optimizations, socket filters and seccomp are using it as assembler. Tracing
+filters may use it as assembler to generate code from kernel. In kernel usage
+may not be bounded by security considerations, since generated eBPF code
+may be optimizing internal code path and not being exposed to the user space.
+Safety of eBPF can come from the verifier.rst. In such use cases as
+described, it may be used as safe instruction set.
+
+Just like the original BPF, eBPF runs within a controlled environment,
+is deterministic and the kernel can easily prove that. The safety of the program
+can be determined in two steps: first step does depth-first-search to disallow
+loops and other CFG validation; second step starts from the first insn and
+descends all possible paths. It simulates execution of every insn and observes
+the state change of registers and stack.
+
+opcode encoding
+===============
+
+eBPF is reusing most of the opcode encoding from classic to simplify conversion
+of classic BPF to eBPF.
+
+For arithmetic and jump instructions the 8-bit 'code' field is divided into three
+parts::
+
+ +----------------+--------+--------------------+
+ | 4 bits | 1 bit | 3 bits |
+ | operation code | source | instruction class |
+ +----------------+--------+--------------------+
+ (MSB) (LSB)
+
+Three LSB bits store instruction class which is one of:
+
+ =================== ===============
+ Classic BPF classes eBPF classes
+ =================== ===============
+ BPF_LD 0x00 BPF_LD 0x00
+ BPF_LDX 0x01 BPF_LDX 0x01
+ BPF_ST 0x02 BPF_ST 0x02
+ BPF_STX 0x03 BPF_STX 0x03
+ BPF_ALU 0x04 BPF_ALU 0x04
+ BPF_JMP 0x05 BPF_JMP 0x05
+ BPF_RET 0x06 BPF_JMP32 0x06
+ BPF_MISC 0x07 BPF_ALU64 0x07
+ =================== ===============
+
+The 4th bit encodes the source operand ...
+
+ ::
+
+ BPF_K 0x00
+ BPF_X 0x08
+
+ * in classic BPF, this means::
+
+ BPF_SRC(code) == BPF_X - use register X as source operand
+ BPF_SRC(code) == BPF_K - use 32-bit immediate as source operand
+
+ * in eBPF, this means::
+
+ BPF_SRC(code) == BPF_X - use 'src_reg' register as source operand
+ BPF_SRC(code) == BPF_K - use 32-bit immediate as source operand
+
+... and four MSB bits store operation code.
+
+If BPF_CLASS(code) == BPF_ALU or BPF_ALU64 [ in eBPF ], BPF_OP(code) is one of::
+
+ BPF_ADD 0x00
+ BPF_SUB 0x10
+ BPF_MUL 0x20
+ BPF_DIV 0x30
+ BPF_OR 0x40
+ BPF_AND 0x50
+ BPF_LSH 0x60
+ BPF_RSH 0x70
+ BPF_NEG 0x80
+ BPF_MOD 0x90
+ BPF_XOR 0xa0
+ BPF_MOV 0xb0 /* eBPF only: mov reg to reg */
+ BPF_ARSH 0xc0 /* eBPF only: sign extending shift right */
+ BPF_END 0xd0 /* eBPF only: endianness conversion */
+
+If BPF_CLASS(code) == BPF_JMP or BPF_JMP32 [ in eBPF ], BPF_OP(code) is one of::
+
+ BPF_JA 0x00 /* BPF_JMP only */
+ BPF_JEQ 0x10
+ BPF_JGT 0x20
+ BPF_JGE 0x30
+ BPF_JSET 0x40
+ BPF_JNE 0x50 /* eBPF only: jump != */
+ BPF_JSGT 0x60 /* eBPF only: signed '>' */
+ BPF_JSGE 0x70 /* eBPF only: signed '>=' */
+ BPF_CALL 0x80 /* eBPF BPF_JMP only: function call */
+ BPF_EXIT 0x90 /* eBPF BPF_JMP only: function return */
+ BPF_JLT 0xa0 /* eBPF only: unsigned '<' */
+ BPF_JLE 0xb0 /* eBPF only: unsigned '<=' */
+ BPF_JSLT 0xc0 /* eBPF only: signed '<' */
+ BPF_JSLE 0xd0 /* eBPF only: signed '<=' */
+
+So BPF_ADD | BPF_X | BPF_ALU means 32-bit addition in both classic BPF
+and eBPF. There are only two registers in classic BPF, so it means A += X.
+In eBPF it means dst_reg = (u32) dst_reg + (u32) src_reg; similarly,
+BPF_XOR | BPF_K | BPF_ALU means A ^= imm32 in classic BPF and analogous
+src_reg = (u32) src_reg ^ (u32) imm32 in eBPF.
+
+Classic BPF is using BPF_MISC class to represent A = X and X = A moves.
+eBPF is using BPF_MOV | BPF_X | BPF_ALU code instead. Since there are no
+BPF_MISC operations in eBPF, the class 7 is used as BPF_ALU64 to mean
+exactly the same operations as BPF_ALU, but with 64-bit wide operands
+instead. So BPF_ADD | BPF_X | BPF_ALU64 means 64-bit addition, i.e.:
+dst_reg = dst_reg + src_reg
+
+Classic BPF wastes the whole BPF_RET class to represent a single ``ret``
+operation. Classic BPF_RET | BPF_K means copy imm32 into return register
+and perform function exit. eBPF is modeled to match CPU, so BPF_JMP | BPF_EXIT
+in eBPF means function exit only. The eBPF program needs to store return
+value into register R0 before doing a BPF_EXIT. Class 6 in eBPF is used as
+BPF_JMP32 to mean exactly the same operations as BPF_JMP, but with 32-bit wide
+operands for the comparisons instead.
+
+For load and store instructions the 8-bit 'code' field is divided as::
+
+ +--------+--------+-------------------+
+ | 3 bits | 2 bits | 3 bits |
+ | mode | size | instruction class |
+ +--------+--------+-------------------+
+ (MSB) (LSB)
+
+Size modifier is one of ...
+
+::
+
+ BPF_W 0x00 /* word */
+ BPF_H 0x08 /* half word */
+ BPF_B 0x10 /* byte */
+ BPF_DW 0x18 /* eBPF only, double word */
+
+... which encodes size of load/store operation::
+
+ B - 1 byte
+ H - 2 byte
+ W - 4 byte
+ DW - 8 byte (eBPF only)
+
+Mode modifier is one of::
+
+ BPF_IMM 0x00 /* used for 32-bit mov in classic BPF and 64-bit in eBPF */
+ BPF_ABS 0x20
+ BPF_IND 0x40
+ BPF_MEM 0x60
+ BPF_LEN 0x80 /* classic BPF only, reserved in eBPF */
+ BPF_MSH 0xa0 /* classic BPF only, reserved in eBPF */
+ BPF_ATOMIC 0xc0 /* eBPF only, atomic operations */

+====================
+eBPF Instruction Set
+====================
+
+Registers and calling convention
+================================
+
+eBPF has 10 general purpose registers and a read-only frame pointer register,
+all of which are 64-bits wide.
+
+The eBPF calling convention is defined as:
+
+ * R0: return value from function calls, and exit value for eBPF 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 eBPF programs needs to spill/fill them if
+necessary across calls.
+
+Instruction encoding
+====================
+
+eBPF uses 64-bit instructions with the following encoding:
+
+ ============= ======= =============== ==================== ============
+ 32 bits (MSB) 16 bits 4 bits 4 bits 8 bits (LSB)
+ ============= ======= =============== ==================== ============
+ immediate offset source register destination register opcode
+ ============= ======= =============== ==================== ============
+
+Note that most instructions do not use all of the fields.
+Unused fields shall be cleared to zero.
+
+Instruction classes
+-------------------
+
+The three LSB bits of the 'opcode' field store the instruction class:
+
+ ========= ===== ===============================
+ class value description
+ ========= ===== ===============================
+ BPF_LD 0x00 non-standard load operations
+ BPF_LDX 0x01 load into register operations
+ BPF_ST 0x02 store from immediate operations
+ BPF_STX 0x03 store from register operations
+ BPF_ALU 0x04 32-bit arithmetic operations
+ BPF_JMP 0x05 64-bit jump operations
+ BPF_JMP32 0x06 32-bit jump operations
+ BPF_ALU64 0x07 64-bit arithmetic operations
+ ========= ===== ===============================
+
+Arithmetic and jump instructions
+================================
+
+For arithmetic and jump instructions (BPF_ALU, BPF_ALU64, BPF_JMP and
+BPF_JMP32), the 8-bit 'opcode' field is divided into three parts:
+
+ ============== ====== =================
+ 4 bits (MSB) 1 bit 3 bits (LSB)
+ ============== ====== =================
+ operation code source instruction class
+ ============== ====== =================
+
+The 4th bit encodes the source operand:
+
+ ====== ===== ========================================
+ source value description
+ ====== ===== ========================================
+ BPF_K 0x00 use 32-bit immediate as source operand
+ BPF_X 0x08 use 'src_reg' register as source operand
+ ====== ===== ========================================
+
+The four MSB bits store the operation code.
+
+
+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:
+
+ ======== ===== ==========================
+ code value description
+ ======== ===== ==========================
+ BPF_ADD 0x00 dst += src
+ BPF_SUB 0x10 dst -= src

+ BPF_XOR 0xa0 dst ^= src
+ BPF_MOV 0xb0 dst = src
+ BPF_ARSH 0xc0 sign extending shift right
+ BPF_END 0xd0 endianness conversion

+
+BPF_ADD | BPF_X | BPF_ALU means::
+
+ dst_reg = (u32) dst_reg + (u32) src_reg;

+BPF_ADD | BPF_X | BPF_ALU64 means::
+
+ dst_reg = dst_reg + src_reg
+
+BPF_XOR | BPF_K | BPF_ALU means::
+
+ src_reg = (u32) src_reg ^ (u32) imm32
+
+BPF_XOR | BPF_K | BPF_ALU64 means::
+
+ src_reg = src_reg ^ imm32
+
+
+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:
+
+ ======== ===== ========================= ============
+ code value description notes
+ ======== ===== ========================= ============
+ BPF_JA 0x00 PC += off BPF_JMP only
+ BPF_JEQ 0x10 PC += off if dst == src

+ BPF_JLE 0xb0 PC += off if dst <= src unsigned
+ BPF_JSLT 0xc0 PC += off if dst < src signed
+ BPF_JSLE 0xd0 PC += off if dst <= src signed
+ ======== ===== ========================= ============
+
+The eBPF program needs to store the return value into register R0 before doing a
+BPF_EXIT.
+
+
+Load and store instructions
+===========================
+
+For load and store instructions (BPF_LD, BPF_LDX, BPF_ST and BPF_STX), the
+8-bit 'opcode' field is divided as:
+
+ ============ ====== =================
+ 3 bits (MSB) 2 bits 3 bits (LSB)
+ ============ ====== =================

+ BPF_W 0x00 word (4 bytes)
+ BPF_H 0x08 half word (2 bytes)
+ BPF_B 0x10 byte

+ BPF_IND 0x40 legacy BPF packet access
+ BPF_MEM 0x60 all normal load and store operations
+ BPF_ATOMIC 0xc0 atomic operations
+ ============= ===== ====================================
+
+BPF_MEM | <size> | BPF_STX means::
+
+ *(size *) (dst_reg + off) = src_reg
+
+BPF_MEM | <size> | BPF_ST means::
+
+ *(size *) (dst_reg + off) = imm32
+
+BPF_MEM | <size> | BPF_LDX means::
+
+ dst_reg = *(size *) (src_reg + off)
+
+Where size is one of: BPF_B or BPF_H or BPF_W or BPF_DW.
+
+Atomic operations
+-----------------
+
+eBPF includes atomic operations, which use the immediate field for extra
+encoding::
+
+ .imm = BPF_ADD, .code = BPF_ATOMIC | BPF_W | BPF_STX: lock xadd *(u32 *)(dst_reg + off16) += src_reg
+ .imm = BPF_ADD, .code = BPF_ATOMIC | BPF_DW | BPF_STX: lock xadd *(u64 *)(dst_reg + off16) += src_reg
+
+The basic atomic operations supported are::
+
+ BPF_ADD
+ BPF_AND
+ BPF_OR
+ BPF_XOR
+
+Each having equivalent semantics with the ``BPF_ADD`` example, that is: the
+memory location addresed by ``dst_reg + off`` is atomically modified, with
+``src_reg`` as the other operand. If the ``BPF_FETCH`` flag is set in the
+immediate, then these operations also overwrite ``src_reg`` with the
+value that was in memory before it was modified.
+
+The more special operations are::
+
+ BPF_XCHG
+
+This atomically exchanges ``src_reg`` with the value addressed by ``dst_reg +
+off``. ::
+
+ BPF_CMPXCHG
+
+This atomically compares the value addressed by ``dst_reg + off`` with
+``R0``. If they match it is replaced with ``src_reg``. In either case, the
+value that was there before is zero-extended and loaded back to ``R0``.
+
+Note that 1 and 2 byte atomic operations are not supported.
+
+Clang can generate atomic instructions by default when ``-mcpu=v3`` is
+enabled. If a lower version for ``-mcpu`` is set, the only atomic instruction
+Clang can generate is ``BPF_ADD`` *without* ``BPF_FETCH``. If you need to enable
+the atomics features, while keeping a lower ``-mcpu`` version, you can use
+``-Xclang -target-feature -Xclang +alu32``.
+
+You may encounter ``BPF_XADD`` - this is a legacy name for ``BPF_ATOMIC``,
+referring to the exclusive-add operation encoded when the immediate field is
+zero.
+
+16-byte instructions
+--------------------
+
+eBPF has one 16-byte instruction: ``BPF_LD | BPF_DW | BPF_IMM`` which consists
+of two consecutive ``struct bpf_insn`` 8-byte blocks and interpreted as single
+instruction that loads 64-bit immediate value into a dst_reg.
+
+Packet access instructions
+--------------------------
+
+eBPF has two non-generic instructions: (BPF_ABS | <size> | BPF_LD) and
+(BPF_IND | <size> | BPF_LD) which are used to access packet data.
+
+They had to be carried over from classic BPF to have strong performance of
+socket filters running in eBPF interpreter. These instructions can only
+be used when interpreter context is a pointer to ``struct sk_buff`` and
+have seven implicit operands. Register R6 is an implicit input that must
+contain pointer to sk_buff. Register R0 is an implicit output which contains
+the data fetched from the packet. Registers R1-R5 are scratch registers
+and must not be used to store the data across BPF_ABS | BPF_LD or
+BPF_IND | BPF_LD instructions.
+
+These instructions have implicit program exit condition as well. When
+eBPF program is trying to access the data beyond the packet boundary,
+the interpreter will abort the execution of the program. JIT compilers
+therefore must preserve this property. src_reg and imm32 fields are
+explicit inputs to these instructions.
+
+For example, BPF_IND | BPF_W | BPF_LD means::
+
+ R0 = ntohl(*(u32 *) (((struct sk_buff *) R6)->data + src_reg + imm32))
+
+and R1 - R5 are clobbered.

+eBPF maps
+=========
+
+'maps' is a generic storage of different types for sharing data between kernel
+and userspace.
+
+The maps are accessed from user space via BPF syscall, which has commands:
+
+- create a map with given type and attributes
+ ``map_fd = bpf(BPF_MAP_CREATE, union bpf_attr *attr, u32 size)``
+ using attr->map_type, attr->key_size, attr->value_size, attr->max_entries
+ returns process-local file descriptor or negative error
+
+- lookup key in a given map
+ ``err = bpf(BPF_MAP_LOOKUP_ELEM, union bpf_attr *attr, u32 size)``
+ using attr->map_fd, attr->key, attr->value
+ returns zero and stores found elem into value or negative error
+
+- create or update key/value pair in a given map
+ ``err = bpf(BPF_MAP_UPDATE_ELEM, union bpf_attr *attr, u32 size)``
+ using attr->map_fd, attr->key, attr->value
+ returns zero or negative error
+
+- find and delete element by key in a given map
+ ``err = bpf(BPF_MAP_DELETE_ELEM, union bpf_attr *attr, u32 size)``
+ using attr->map_fd, attr->key
+
+- to delete map: close(fd)
+ Exiting process will delete maps automatically
+
+userspace programs use this syscall to create/access maps that eBPF programs
+are concurrently updating.
+
+maps can have different types: hash, array, bloom filter, radix-tree, etc.
+
+The map is defined by:
+
+ - type
+ - max number of elements
+ - key size in bytes
+ - value size in bytes

+eBPF verifier
+=============
+
+The safety of the eBPF program is determined in two steps.
+
+First step does DAG check to disallow loops and other CFG validation.
+In particular it will detect programs that have unreachable instructions.
+(though classic BPF checker allows them)
+
+Second step starts from the first insn and descends all possible paths.
+It simulates execution of every insn and observes the state change of
+registers and stack.
+
+At the start of the program the register R1 contains a pointer to context
+and has type PTR_TO_CTX.
+If verifier sees an insn that does R2=R1, then R2 has now type
+PTR_TO_CTX as well and can be used on the right hand side of expression.
+If R1=PTR_TO_CTX and insn is R2=R1+R1, then R2=SCALAR_VALUE,
+since addition of two valid pointers makes invalid pointer.
+(In 'secure' mode verifier will reject any type of pointer arithmetic to make
+sure that kernel addresses don't leak to unprivileged users)
+
+If register was never written to, it's not readable::
+
+ bpf_mov R0 = R2
+ bpf_exit
+
+will be rejected, since R2 is unreadable at the start of the program.
+
+After kernel function call, R1-R5 are reset to unreadable and
+R0 has a return type of the function.
+
+Since R6-R9 are callee saved, their state is preserved across the call.
+
+::
+
+ bpf_mov R6 = 1
+ bpf_call foo
+ bpf_mov R0 = R6
+ bpf_exit
+
+is a correct program. If there was R1 instead of R6, it would have
+been rejected.
+
+load/store instructions are allowed only with registers of valid types, which
+are PTR_TO_CTX, PTR_TO_MAP, PTR_TO_STACK. They are bounds and alignment checked.
+For example::
+
+ bpf_mov R1 = 1
+ bpf_mov R2 = 2
+ bpf_xadd *(u32 *)(R1 + 3) += R2
+ bpf_exit
+
+will be rejected, since R1 doesn't have a valid pointer type at the time of
+execution of instruction bpf_xadd.
+
+At the start R1 type is PTR_TO_CTX (a pointer to generic ``struct bpf_context``)
+A callback is used to customize verifier to restrict eBPF program access to only
+certain fields within ctx structure with specified size and alignment.
+
+For example, the following insn::
+
+ bpf_ld R0 = *(u32 *)(R6 + 8)
+
+intends to load a word from address R6 + 8 and store it into R0
+If R6=PTR_TO_CTX, via is_valid_access() callback the verifier will know
+that offset 8 of size 4 bytes can be accessed for reading, otherwise
+the verifier will reject the program.
+If R6=PTR_TO_STACK, then access should be aligned and be within
+stack bounds, which are [-MAX_BPF_STACK, 0). In this example offset is 8,
+so it will fail verification, since it's out of bounds.
+
+The verifier will allow eBPF program to read data from stack only after
+it wrote into it.
+
+Classic BPF verifier does similar check with M[0-15] memory slots.
+For example::
+
+ bpf_ld R0 = *(u32 *)(R10 - 4)
+ bpf_exit
+
+is invalid program.
+Though R10 is correct read-only register and has type PTR_TO_STACK
+and R10 - 4 is within stack bounds, there were no stores into that location.
+
+Pointer register spill/fill is tracked as well, since four (R6-R9)
+callee saved registers may not be enough for some programs.
+
+Allowed function calls are customized with bpf_verifier_ops->get_func_proto()
+The eBPF verifier will check that registers match argument constraints.
+After the call register R0 will be set to return type of the function.
+
+Function calls is a main mechanism to extend functionality of eBPF programs.
+Socket filters may let programs to call one set of functions, whereas tracing
+filters may allow completely different set.
+
+If a function made accessible to eBPF program, it needs to be thought through
+from safety point of view. The verifier will guarantee that the function is
+called with valid arguments.
+
+seccomp vs socket filters have different security restrictions for classic BPF.
+Seccomp solves this by two stage verifier: classic BPF verifier is followed
+by seccomp verifier. In case of eBPF one configurable verifier is shared for
+all use cases.
+
+See details of eBPF verifier in kernel/bpf/verifier.c
+
+Register value tracking
+=======================
+
+In order to determine the safety of an eBPF program, the verifier must track
+the range of possible values in each register and also in each stack slot.
+This is done with ``struct bpf_reg_state``, defined in include/linux/
+bpf_verifier.h, which unifies tracking of scalar and pointer values. Each
+register state has a type, which is either NOT_INIT (the register has not been
+written to), SCALAR_VALUE (some value which is not usable as a pointer), or a
+pointer type. The types of pointers describe their base, as follows:
+
+
+ PTR_TO_CTX
+ Pointer to bpf_context.
+ CONST_PTR_TO_MAP
+ Pointer to struct bpf_map. "Const" because arithmetic
+ on these pointers is forbidden.
+ PTR_TO_MAP_VALUE
+ Pointer to the value stored in a map element.
+ PTR_TO_MAP_VALUE_OR_NULL
+ Either a pointer to a map value, or NULL; map accesses
+ (see maps.rst) return this type, which becomes a
+ PTR_TO_MAP_VALUE when checked != NULL. Arithmetic on
+ these pointers is forbidden.
+ PTR_TO_STACK
+ Frame pointer.
+ PTR_TO_PACKET
+ skb->data.
+ PTR_TO_PACKET_END
+ skb->data + headlen; arithmetic forbidden.
+ PTR_TO_SOCKET
+ Pointer to struct bpf_sock_ops, implicitly refcounted.
+ PTR_TO_SOCKET_OR_NULL
+ Either a pointer to a socket, or NULL; socket lookup
+ returns this type, which becomes a PTR_TO_SOCKET when
+ checked != NULL. PTR_TO_SOCKET is reference-counted,
+ so programs must release the reference through the
+ socket release function before the end of the program.
+ Arithmetic on these pointers is forbidden.
+
+However, a pointer may be offset from this base (as a result of pointer
+arithmetic), and this is tracked in two parts: the 'fixed offset' and 'variable
+offset'. The former is used when an exactly-known value (e.g. an immediate
+operand) is added to a pointer, while the latter is used for values which are
+not exactly known. The variable offset is also used in SCALAR_VALUEs, to track
+the range of possible values in the register.
+
+The verifier's knowledge about the variable offset consists of:
+
+* minimum and maximum values as unsigned
+* minimum and maximum values as signed
+
+* knowledge of the values of individual bits, in the form of a 'tnum': a u64
+ 'mask' and a u64 'value'. 1s in the mask represent bits whose value is unknown;
+ 1s in the value represent bits known to be 1. Bits known to be 0 have 0 in both
+ mask and value; no bit should ever be 1 in both. For example, if a byte is read
+ into a register from memory, the register's top 56 bits are known zero, while
+ the low 8 are unknown - which is represented as the tnum (0x0; 0xff). If we
+ then OR this with 0x40, we get (0x40; 0xbf), then if we add 1 we get (0x0;
+ 0x1ff), because of potential carries.
+
+Besides arithmetic, the register state can also be updated by conditional
+branches. For instance, if a SCALAR_VALUE is compared > 8, in the 'true' branch
+it will have a umin_value (unsigned minimum value) of 9, whereas in the 'false'
+branch it will have a umax_value of 8. A signed compare (with BPF_JSGT or
+BPF_JSGE) would instead update the signed minimum/maximum values. Information
+from the signed and unsigned bounds can be combined; for instance if a value is
+first tested < 8 and then tested s> 4, the verifier will conclude that the value
+is also > 4 and s< 8, since the bounds prevent crossing the sign boundary.
+
+PTR_TO_PACKETs with a variable offset part have an 'id', which is common to all
+pointers sharing that same variable offset. This is important for packet range
+checks: after adding a variable to a packet pointer register A, if you then copy
+it to another register B and then add a constant 4 to A, both registers will
+share the same 'id' but the A will have a fixed offset of +4. Then if A is
+bounds-checked and found to be less than a PTR_TO_PACKET_END, the register B is
+now known to have a safe range of at least 4 bytes. See 'Direct packet access',
+below, for more on PTR_TO_PACKET ranges.
+
+The 'id' field is also used on PTR_TO_MAP_VALUE_OR_NULL, common to all copies of
+the pointer returned from a map lookup. This means that when one copy is
+checked and found to be non-NULL, all copies can become PTR_TO_MAP_VALUEs.
+As well as range-checking, the tracked information is also used for enforcing
+alignment of pointer accesses. For instance, on most systems the packet pointer
+is 2 bytes after a 4-byte alignment. If a program adds 14 bytes to that to jump
+over the Ethernet header, then reads IHL and addes (IHL * 4), the resulting
+pointer will have a variable offset known to be 4n+2 for some n, so adding the 2
+bytes (NET_IP_ALIGN) gives a 4-byte alignment and so word-sized accesses through
+that pointer are safe.
+The 'id' field is also used on PTR_TO_SOCKET and PTR_TO_SOCKET_OR_NULL, common
+to all copies of the pointer returned from a socket lookup. This has similar
+behaviour to the handling for PTR_TO_MAP_VALUE_OR_NULL->PTR_TO_MAP_VALUE, but
+it also handles reference tracking for the pointer. PTR_TO_SOCKET implicitly
+represents a reference to the corresponding ``struct sock``. To ensure that the
+reference is not leaked, it is imperative to NULL-check the reference and in
+the non-NULL case, and pass the valid reference to the socket release function.
+
+Direct packet access
+====================
+
+In cls_bpf and act_bpf programs the verifier allows direct access to the packet
+data via skb->data and skb->data_end pointers.
+Ex::
+
+ 1: r4 = *(u32 *)(r1 +80) /* load skb->data_end */
+ 2: r3 = *(u32 *)(r1 +76) /* load skb->data */
+ 3: r5 = r3
+ 4: r5 += 14
+ 5: if r5 > r4 goto pc+16
+ R1=ctx R3=pkt(id=0,off=0,r=14) R4=pkt_end R5=pkt(id=0,off=14,r=14) R10=fp
+ 6: r0 = *(u16 *)(r3 +12) /* access 12 and 13 bytes of the packet */
+
+this 2byte load from the packet is safe to do, since the program author
+did check ``if (skb->data + 14 > skb->data_end) goto err`` at insn #5 which
+means that in the fall-through case the register R3 (which points to skb->data)
+has at least 14 directly accessible bytes. The verifier marks it
+as R3=pkt(id=0,off=0,r=14).
+id=0 means that no additional variables were added to the register.
+off=0 means that no additional constants were added.
+r=14 is the range of safe access which means that bytes [R3, R3 + 14) are ok.
+Note that R5 is marked as R5=pkt(id=0,off=14,r=14). It also points
+to the packet data, but constant 14 was added to the register, so
+it now points to ``skb->data + 14`` and accessible range is [R5, R5 + 14 - 14)
+which is zero bytes.
+
+More complex packet access may look like::
+
+
+ R0=inv1 R1=ctx R3=pkt(id=0,off=0,r=14) R4=pkt_end R5=pkt(id=0,off=14,r=14) R10=fp
+ 6: r0 = *(u8 *)(r3 +7) /* load 7th byte from the packet */
+ 7: r4 = *(u8 *)(r3 +12)
+ 8: r4 *= 14
+ 9: r3 = *(u32 *)(r1 +76) /* load skb->data */
+ 10: r3 += r4
+ 11: r2 = r1
+ 12: r2 <<= 48
+ 13: r2 >>= 48
+ 14: r3 += r2
+ 15: r2 = r3
+ 16: r2 += 8
+ 17: r1 = *(u32 *)(r1 +80) /* load skb->data_end */
+ 18: if r2 > r1 goto pc+2
+ R0=inv(id=0,umax_value=255,var_off=(0x0; 0xff)) R1=pkt_end R2=pkt(id=2,off=8,r=8) R3=pkt(id=2,off=0,r=8) R4=inv(id=0,umax_value=3570,var_off=(0x0; 0xfffe)) R5=pkt(id=0,off=14,r=14) R10=fp
+ 19: r1 = *(u8 *)(r3 +4)
+
+The state of the register R3 is R3=pkt(id=2,off=0,r=8)
+id=2 means that two ``r3 += rX`` instructions were seen, so r3 points to some
+offset within a packet and since the program author did
+``if (r3 + 8 > r1) goto err`` at insn #18, the safe range is [R3, R3 + 8).
+The verifier only allows 'add'/'sub' operations on packet registers. Any other
+operation will set the register state to 'SCALAR_VALUE' and it won't be
+available for direct packet access.
+
+Operation ``r3 += rX`` may overflow and become less than original skb->data,
+therefore the verifier has to prevent that. So when it sees ``r3 += rX``
+instruction and rX is more than 16-bit value, any subsequent bounds-check of r3
+against skb->data_end will not give us 'range' information, so attempts to read
+through the pointer will give "invalid access to packet" error.
+
+Ex. after insn ``r4 = *(u8 *)(r3 +12)`` (insn #7 above) the state of r4 is
+R4=inv(id=0,umax_value=255,var_off=(0x0; 0xff)) which means that upper 56 bits
+of the register are guaranteed to be zero, and nothing is known about the lower
+8 bits. After insn ``r4 *= 14`` the state becomes
+R4=inv(id=0,umax_value=3570,var_off=(0x0; 0xfffe)), since multiplying an 8-bit
+value by constant 14 will keep upper 52 bits as zero, also the least significant
+bit will be zero as 14 is even. Similarly ``r2 >>= 48`` will make
+R2=inv(id=0,umax_value=65535,var_off=(0x0; 0xffff)), since the shift is not sign
+extending. This logic is implemented in adjust_reg_min_max_vals() function,
+which calls adjust_ptr_min_max_vals() for adding pointer to scalar (or vice
+versa) and adjust_scalar_min_max_vals() for operations on two scalars.
+
+The end result is that bpf program author can access packet directly
+using normal C code as::
+
+ void *data = (void *)(long)skb->data;
+ void *data_end = (void *)(long)skb->data_end;
+ struct eth_hdr *eth = data;
+ struct iphdr *iph = data + sizeof(*eth);
+ struct udphdr *udp = data + sizeof(*eth) + sizeof(*iph);
+
+ if (data + sizeof(*eth) + sizeof(*iph) + sizeof(*udp) > data_end)
+ return 0;
+ if (eth->h_proto != htons(ETH_P_IP))
+ return 0;
+ if (iph->protocol != IPPROTO_UDP || iph->ihl != 5)
+ return 0;
+ if (udp->dest == 53 || udp->source == 9)
+ ...;
+
+which makes such programs easier to write comparing to LD_ABS insn
+and significantly faster.
+
+Pruning
+=======
+
+The verifier does not actually walk all possible paths through the program. For
+each new branch to analyse, the verifier looks at all the states it's previously
+been in when at this instruction. If any of them contain the current state as a
+subset, the branch is 'pruned' - that is, the fact that the previous state was
+accepted implies the current state would be as well. For instance, if in the
+previous state, r1 held a packet-pointer, and in the current state, r1 holds a
+packet-pointer with a range as long or longer and at least as strict an
+alignment, then r1 is safe. Similarly, if r2 was NOT_INIT before then it can't
+have been used by any path from that point, so any value in r2 (including
+another NOT_INIT) is safe. The implementation is in the function regsafe().
+Pruning considers not only the registers but also the stack (and any spilled
+registers it may hold). They must all be safe for the branch to be pruned.
+This is implemented in states_equal().
+
+Understanding eBPF verifier messages
+====================================
+
+The following are few examples of invalid eBPF programs and verifier error
+messages as seen in the log:

@@ -268,6 +268,56 @@ marked operations, if all accesses to a variable that is accessed concurrently
are properly marked, KCSAN will never trigger a watchpoint and therefore never
report the accesses.
+Modeling Weak Memory
+~~~~~~~~~~~~~~~~~~~~
+
+KCSAN's approach to detecting data races due to missing memory barriers is
+based on modeling access reordering (with ``CONFIG_KCSAN_WEAK_MEMORY=y``).
+Each plain memory access for which a watchpoint is set up, is also selected for
+simulated reordering within the scope of its function (at most 1 in-flight
+access).
+
+Once an access has been selected for reordering, it is checked along every
+other access until the end of the function scope. If an appropriate memory
+barrier is encountered, the access will no longer be considered for simulated
+reordering.
+
+When the result of a memory operation should be ordered by a barrier, KCSAN can
+then detect data races where the conflict only occurs as a result of a missing
+barrier. Consider the example::
+
+ int x, flag;
+ void T1(void)
+ {
+ x = 1; // data race!
+ WRITE_ONCE(flag, 1); // correct: smp_store_release(&flag, 1)
+ }
+ void T2(void)
+ {
+ while (!READ_ONCE(flag)); // correct: smp_load_acquire(&flag)
+ ... = x; // data race!
+ }
+
+When weak memory modeling is enabled, KCSAN can consider ``x`` in ``T1`` for
+simulated reordering. After the write of ``flag``, ``x`` is again checked for
+concurrent accesses: because ``T2`` is able to proceed after the write of
+``flag``, a data race is detected. With the correct barriers in place, ``x``
+would not be considered for reordering after the proper release of ``flag``,
+and no data race would be detected.
+
+Deliberate trade-offs in complexity but also practical limitations mean only a
+subset of data races due to missing memory barriers can be detected. With
+currently available compiler support, the implementation is limited to modeling
+the effects of "buffering" (delaying accesses), since the runtime cannot
+"prefetch" accesses. Also recall that watchpoints are only set up for plain
+accesses, and the only access type for which KCSAN simulates reordering. This
+means reordering of marked accesses is not modeled.
+
+A consequence of the above is that acquire operations do not require barrier
+instrumentation (no prefetching). Furthermore, marked accesses introducing
+address or control dependencies do not require special handling (the marked
+access cannot be reordered, later dependent accesses cannot be prefetched).

+========================================
+The Kernel Test Anything Protocol (KTAP)
+========================================
+
+TAP, or the Test Anything Protocol is a format for specifying test results used
+by a number of projects. It's website and specification are found at this `link
+<https://testanything.org/>`_. The Linux Kernel largely uses TAP output for test
+results. However, Kernel testing frameworks have special needs for test results
+which don't align with the original TAP specification. Thus, a "Kernel TAP"
+(KTAP) format is specified to extend and alter TAP to support these use-cases.
+This specification describes the generally accepted format of KTAP as it is
+currently used in the kernel.
+
+KTAP test results describe a series of tests (which may be nested: i.e., test
+can have subtests), each of which can contain both diagnostic data -- e.g., log
+lines -- and a final result. The test structure and results are
+machine-readable, whereas the diagnostic data is unstructured and is there to
+aid human debugging.
+
+KTAP output is built from four different types of lines:
+- Version lines
+- Plan lines
+- Test case result lines
+- Diagnostic lines
+
+In general, valid KTAP output should also form valid TAP output, but some
+information, in particular nested test results, may be lost. Also note that
+there is a stagnant draft specification for TAP14, KTAP diverges from this in
+a couple of places (notably the "Subtest" header), which are described where
+relevant later in this document.
+
+Version lines
+-------------
+
+All KTAP-formatted results begin with a "version line" which specifies which
+version of the (K)TAP standard the result is compliant with.
+
+For example:
+- "KTAP version 1"
+- "TAP version 13"
+- "TAP version 14"
+
+Note that, in KTAP, subtests also begin with a version line, which denotes the
+start of the nested test results. This differs from TAP14, which uses a
+separate "Subtest" line.
+
+While, going forward, "KTAP version 1" should be used by compliant tests, it
+is expected that most parsers and other tooling will accept the other versions
+listed here for compatibility with existing tests and frameworks.
+
+Plan lines
+----------
+
+A test plan provides the number of tests (or subtests) in the KTAP output.
+
+Plan lines must follow the format of "1..N" where N is the number of tests or subtests.
+Plan lines follow version lines to indicate the number of nested tests.
+
+While there are cases where the number of tests is not known in advance -- in
+which case the test plan may be omitted -- it is strongly recommended one is
+present where possible.
+
+Test case result lines
+----------------------
+
+Test case result lines indicate the final status of a test.
+They are required and must have the format:
+
+.. code-block::
+
+ <result> <number> [<description>][ # [<directive>] [<diagnostic data>]]
+
+The result can be either "ok", which indicates the test case passed,
+or "not ok", which indicates that the test case failed.
+
+<number> represents the number of the test being performed. The first test must
+have the number 1 and the number then must increase by 1 for each additional
+subtest within the same test at the same nesting level.
+
+The description is a description of the test, generally the name of
+the test, and can be any string of words (can't include #). The
+description is optional, but recommended.
+
+The directive and any diagnostic data is optional. If either are present, they
+must follow a hash sign, "#".
+
+A directive is a keyword that indicates a different outcome for a test other
+than passed and failed. The directive is optional, and consists of a single
+keyword preceding the diagnostic data. In the event that a parser encounters
+a directive it doesn't support, it should fall back to the "ok" / "not ok"
+result.
+
+Currently accepted directives are:
+
+- "SKIP", which indicates a test was skipped (note the result of the test case
+ result line can be either "ok" or "not ok" if the SKIP directive is used)
+- "TODO", which indicates that a test is not expected to pass at the moment,
+ e.g. because the feature it is testing is known to be broken. While this
+ directive is inherited from TAP, its use in the kernel is discouraged.
+- "XFAIL", which indicates that a test is expected to fail. This is similar
+ to "TODO", above, and is used by some kselftest tests.
+- “TIMEOUTâ€, which indicates a test has timed out (note the result of the test
+ case result line should be “not ok†if the TIMEOUT directive is used)
+- “ERRORâ€, which indicates that the execution of a test has failed due to a
+ specific error that is included in the diagnostic data. (note the result of
+ the test case result line should be “not ok†if the ERROR directive is used)
+
+The diagnostic data is a plain-text field which contains any additional details
+about why this result was produced. This is typically an error message for ERROR
+or failed tests, or a description of missing dependencies for a SKIP result.
+
+The diagnostic data field is optional, and results which have neither a
+directive nor any diagnostic data do not need to include the "#" field
+separator.
+
+Example result lines include:
+
+.. code-block::
+
+ ok 1 test_case_name
+
+The test "test_case_name" passed.
+
+.. code-block::
+
+ not ok 1 test_case_name
+
+The test "test_case_name" failed.
+
+.. code-block::
+
+ ok 1 test # SKIP necessary dependency unavailable
+
+The test "test" was SKIPPED with the diagnostic message "necessary dependency
+unavailable".
+
+.. code-block::
+
+ not ok 1 test # TIMEOUT 30 seconds
+
+The test "test" timed out, with diagnostic data "30 seconds".
+
+.. code-block::
+
+ ok 5 check return code # rcode=0
+
+The test "check return code" passed, with additional diagnostic data “rcode=0â€
+
+
+Diagnostic lines
+----------------
+
+If tests wish to output any further information, they should do so using
+"diagnostic lines". Diagnostic lines are optional, freeform text, and are
+often used to describe what is being tested and any intermediate results in
+more detail than the final result and diagnostic data line provides.
+
+Diagnostic lines are formatted as "# <diagnostic_description>", where the
+description can be any string. Diagnostic lines can be anywhere in the test
+output. As a rule, diagnostic lines regarding a test are directly before the
+test result line for that test.
+
+Note that most tools will treat unknown lines (see below) as diagnostic lines,
+even if they do not start with a "#": this is to capture any other useful
+kernel output which may help debug the test. It is nevertheless recommended
+that tests always prefix any diagnostic output they have with a "#" character.
+
+Unknown lines
+-------------
+
+There may be lines within KTAP output that do not follow the format of one of
+the four formats for lines described above. This is allowed, however, they will
+not influence the status of the tests.
+
+Nested tests
+------------
+
+In KTAP, tests can be nested. This is done by having a test include within its
+output an entire set of KTAP-formatted results. This can be used to categorize
+and group related tests, or to split out different results from the same test.
+
+The "parent" test's result should consist of all of its subtests' results,
+starting with another KTAP version line and test plan, and end with the overall
+result. If one of the subtests fail, for example, the parent test should also

+
+Additionally, all result lines in a subtest should be indented. One level of
+indentation is two spaces: " ". The indentation should begin at the version
+line and should end before the parent test's result line.

+An example of a test with two nested subtests:
+
+.. code-block::

+ KTAP version 1

+ KTAP version 1
+ 1..2
+ KTAP version 1
+ 1..2
+ not ok 1 test_1
+ ok 2 test_2
+ not ok 1 test_3
+ ok 2 test_4 # SKIP
+ not ok 1 example_test_1
+ ok 2 example_test_2
+
+
+Major differences between TAP and KTAP
+--------------------------------------
+
+Note the major differences between the TAP and KTAP specification:
+- yaml and json are not recommended in diagnostic messages
+- TODO directive not recognized
+- KTAP allows for an arbitrary number of tests to be nested
+
+The TAP14 specification does permit nested tests, but instead of using another
+nested version line, uses a line of the form
+"Subtest: <name>" where <name> is the name of the parent test.
+
+Example KTAP output
+--------------------
+.. code-block::
+
+ KTAP version 1
+ 1..1
+ KTAP version 1
+ 1..3
+ KTAP version 1
+ 1..1
+ # test_1: initializing test_1
+ ok 1 test_1
+ ok 1 example_test_1
+ KTAP version 1
+ 1..2
+ ok 1 test_1 # SKIP test_1 skipped
+ ok 2 test_2
+ ok 2 example_test_2
+ KTAP version 1
+ 1..3
+ ok 1 test_1
+ # test_2: FAIL
+ not ok 2 test_2
+ ok 3 test_3 # SKIP test_3 skipped
+ not ok 3 example_test_3
+ not ok 1 main_test
+
+This output defines the following hierarchy:
+
+A single test called "main_test", which fails, and has three subtests:
+- "example_test_1", which passes, and has one subtest:
+
+ - "test_1", which passes, and outputs the diagnostic message "test_1: initializing test_1"
+
+- "example_test_2", which passes, and has two subtests:
+
+ - "test_1", which is skipped, with the explanation "test_1 skipped"
+ - "test_2", which passes
+
+- "example_test_3", which fails, and has three subtests
+
+ - "test_1", which passes
+ - "test_2", which outputs the diagnostic line "test_2: FAIL", and fails.
+ - "test_3", which is skipped with the explanation "test_3 skipped"
+
+Note that the individual subtests with the same names do not conflict, as they
+are found in different parent tests. This output also exhibits some sensible
+rules for "bubbling up" test results: a test fails if any of its subtests fail.
+Skipped tests do not affect the result of the parent test (though it often
+makes sense for a test to be marked skipped if _all_ of its subtests have been
+skipped).

+==================
+KUnit Architecture
+==================
+
+The KUnit architecture can be divided into two parts:
+
+- Kernel testing library
+- kunit_tool (Command line test harness)
+
+In-Kernel Testing Framework
+===========================
+
+The kernel testing library supports KUnit tests written in C using
+KUnit. KUnit tests are kernel code. KUnit does several things:
+
+- Organizes tests
+- Reports test results
+- Provides test utilities
+
+Test Cases
+----------
+
+The fundamental unit in KUnit is the test case. The KUnit test cases are
+grouped into KUnit suites. A KUnit test case is a function with type
+signature ``void (*)(struct kunit *test)``.
+These test case functions are wrapped in a struct called
+``struct kunit_case``. For code, see:
+
+.. kernel-doc:: include/kunit/test.h
+ :identifiers: kunit_case
+
+.. note:
+ ``generate_params`` is optional for non-parameterized tests.
+
+Each KUnit test case gets a ``struct kunit`` context
+object passed to it that tracks a running test. The KUnit assertion
+macros and other KUnit utilities use the ``struct kunit`` context
+object. As an exception, there are two fields:
+
+- ``->priv``: The setup functions can use it to store arbitrary test
+ user data.
+
+- ``->param_value``: It contains the parameter value which can be
+ retrieved in the parameterized tests.
+
+Test Suites
+-----------
+
+A KUnit suite includes a collection of test cases. The KUnit suites
+are represented by the ``struct kunit_suite``. For example:
+
+.. code-block:: c
+
+ static struct kunit_case example_test_cases[] = {
+ KUNIT_CASE(example_test_foo),
+ KUNIT_CASE(example_test_bar),
+ KUNIT_CASE(example_test_baz),
+ {}
+ };
+
+ static struct kunit_suite example_test_suite = {
+ .name = "example",
+ .init = example_test_init,
+ .exit = example_test_exit,
+ .test_cases = example_test_cases,
+ };
+ kunit_test_suite(example_test_suite);
+
+In the above example, the test suite ``example_test_suite``, runs the
+test cases ``example_test_foo``, ``example_test_bar``, and
+``example_test_baz``. Before running the test, the ``example_test_init``
+is called and after running the test, ``example_test_exit`` is called.
+The ``kunit_test_suite(example_test_suite)`` registers the test suite
+with the KUnit test framework.
+
+Executor
+--------
+
+The KUnit executor can list and run built-in KUnit tests on boot.
+The Test suites are stored in a linker section
+called ``.kunit_test_suites``. For code, see:
+https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/asm-generic/vmlinux.lds.h?h=v5.15#n945.
+The linker section consists of an array of pointers to
+``struct kunit_suite``, and is populated by the ``kunit_test_suites()``
+macro. To run all tests compiled into the kernel, the KUnit executor
+iterates over the linker section array.
+
+.. kernel-figure:: kunit_suitememorydiagram.svg
+ :alt: KUnit Suite Memory
+
+ KUnit Suite Memory Diagram
+
+On the kernel boot, the KUnit executor uses the start and end addresses
+of this section to iterate over and run all tests. For code, see:
+https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/lib/kunit/executor.c
+
+When built as a module, the ``kunit_test_suites()`` macro defines a
+``module_init()`` function, which runs all the tests in the compilation
+unit instead of utilizing the executor.
+
+In KUnit tests, some error classes do not affect other tests
+or parts of the kernel, each KUnit case executes in a separate thread
+context. For code, see:
+https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/lib/kunit/try-catch.c?h=v5.15#n58
+
+Assertion Macros
+----------------
+
+KUnit tests verify state using expectations/assertions.
+All expectations/assertions are formatted as:
+``KUNIT_{EXPECT|ASSERT}_<op>[_MSG](kunit, property[, message])``
+
+- ``{EXPECT|ASSERT}`` determines whether the check is an assertion or an
+ expectation.
+
+ - For an expectation, if the check fails, marks the test as failed
+ and logs the failure.
+
+ - An assertion, on failure, causes the test case to terminate
+ immediately.
+
+ - Assertions call function:
+ ``void __noreturn kunit_abort(struct kunit *)``.
+
+ - ``kunit_abort`` calls function:
+ ``void __noreturn kunit_try_catch_throw(struct kunit_try_catch *try_catch)``.
+
+ - ``kunit_try_catch_throw`` calls function:
+ ``void complete_and_exit(struct completion *, long) __noreturn;``
+ and terminates the special thread context.
+
+- ``<op>`` denotes a check with options: ``TRUE`` (supplied property
+ has the boolean value “trueâ€), ``EQ`` (two supplied properties are
+ equal), ``NOT_ERR_OR_NULL`` (supplied pointer is not null and does not
+ contain an “err†value).
+
+- ``[_MSG]`` prints a custom message on failure.
+
+Test Result Reporting
+---------------------
+KUnit prints test results in KTAP format. KTAP is based on TAP14, see:
+https://github.com/isaacs/testanything.github.io/blob/tap14/tap-version-14-specification.md.
+KTAP (yet to be standardized format) works with KUnit and Kselftest.
+The KUnit executor prints KTAP results to dmesg, and debugfs
+(if configured).
+
+Parameterized Tests
+-------------------
+
+Each KUnit parameterized test is associated with a collection of
+parameters. The test is invoked multiple times, once for each parameter
+value and the parameter is stored in the ``param_value`` field.
+The test case includes a ``KUNIT_CASE_PARAM()`` macro that accepts a
+generator function.
+The generator function is passed the previous parameter and returns the next
+parameter. It also provides a macro to generate common-case generators based on
+arrays.
+
+For code, see:
+
+.. kernel-doc:: include/kunit/test.h
+ :identifiers: KUNIT_ARRAY_PARAM
+
+
+kunit_tool (Command Line Test Harness)
+======================================
+
+kunit_tool is a Python script ``(tools/testing/kunit/kunit.py)``
+that can be used to configure, build, exec, parse and run (runs other
+commands in order) test results. You can either run KUnit tests using
+kunit_tool or can include KUnit in kernel and parse manually.
+
+- ``configure`` command generates the kernel ``.config`` from a
+ ``.kunitconfig`` file (and any architecture-specific options).
+ For some architectures, additional config options are specified in the
+ ``qemu_config`` Python script
+ (For example: ``tools/testing/kunit/qemu_configs/powerpc.py``).
+ It parses both the existing ``.config`` and the ``.kunitconfig`` files
+ and ensures that ``.config`` is a superset of ``.kunitconfig``.
+ If this is not the case, it will combine the two and run
+ ``make olddefconfig`` to regenerate the ``.config`` file. It then
+ verifies that ``.config`` is now a superset. This checks if all
+ Kconfig dependencies are correctly specified in ``.kunitconfig``.
+ ``kunit_config.py`` includes the parsing Kconfigs code. The code which
+ runs ``make olddefconfig`` is a part of ``kunit_kernel.py``. You can
+ invoke this command via: ``./tools/testing/kunit/kunit.py config`` and
+ generate a ``.config`` file.
+- ``build`` runs ``make`` on the kernel tree with required options
+ (depends on the architecture and some options, for example: build_dir)
+ and reports any errors.
+ To build a KUnit kernel from the current ``.config``, you can use the
+ ``build`` argument: ``./tools/testing/kunit/kunit.py build``.
+- ``exec`` command executes kernel results either directly (using
+ User-mode Linux configuration), or via an emulator such
+ as QEMU. It reads results from the log via standard
+ output (stdout), and passes them to ``parse`` to be parsed.
+ If you already have built a kernel with built-in KUnit tests,
+ you can run the kernel and display the test results with the ``exec``
+ argument: ``./tools/testing/kunit/kunit.py exec``.
+- ``parse`` extracts the KTAP output from a kernel log, parses
+ the test results, and prints a summary. For failed tests, any
+ diagnostic output will be included.

+This section details the kernel unit testing framework.
+
+Introduction
+============
+
+KUnit (Kernel unit testing framework) provides a common framework for
+unit tests within the Linux kernel. Using KUnit, you can define groups
+of test cases called test suites. The tests either run on kernel boot
+if built-in, or load as a module. KUnit automatically flags and reports
+failed test cases in the kernel log. The test results appear in `TAP
+(Test Anything Protocol) format <https://testanything.org/>`_. It is inspired by
+JUnit, Python’s unittest.mock, and GoogleTest/GoogleMock (C++ unit testing
+framework).
+
+KUnit tests are part of the kernel, written in the C (programming)
+language, and test parts of the Kernel implementation (example: a C
+language function). Excluding build time, from invocation to
+completion, KUnit can run around 100 tests in less than 10 seconds.
+KUnit can test any kernel component, for example: file system, system
+calls, memory management, device drivers and so on.
+
+KUnit follows the white-box testing approach. The test has access to
+internal system functionality. KUnit runs in kernel space and is not
+restricted to things exposed to user-space.
+
+In addition, KUnit has kunit_tool, a script (``tools/testing/kunit/kunit.py``)
+that configures the Linux kernel, runs KUnit tests under QEMU or UML (`User Mode
+Linux <http://user-mode-linux.sourceforge.net/>`_), parses the test results and
+displays them in a user friendly manner.
+
+Features
+--------
+
+- Provides a framework for writing unit tests.
+- Runs tests on any kernel architecture.
+- Runs a test in milliseconds.
+
+Prerequisites
+-------------
+
+- Any Linux kernel compatible hardware.
+- For Kernel under test, Linux kernel version 5.5 or greater.
+
+Unit Testing
+============
+
+A unit test tests a single unit of code in isolation. A unit test is the finest
+granularity of testing and allows all possible code paths to be tested in the
+code under test. This is possible if the code under test is small and does not
+have any external dependencies outside of the test's control like hardware.
+
+
+Write Unit Tests
+----------------
+
+To write good unit tests, there is a simple but powerful pattern:
+Arrange-Act-Assert. This is a great way to structure test cases and
+defines an order of operations.
+
+- Arrange inputs and targets: At the start of the test, arrange the data
+ that allows a function to work. Example: initialize a statement or
+ object.
+- Act on the target behavior: Call your function/code under test.
+- Assert expected outcome: Verify that the result (or resulting state) is as
+ expected.
+
+Unit Testing Advantages
+-----------------------
+
+- Increases testing speed and development in the long run.
+- Detects bugs at initial stage and therefore decreases bug fix cost
+ compared to acceptance testing.
+- Improves code quality.
+- Encourages writing testable code.

+Run Tests without kunit_tool
+============================
+
+If we do not want to use kunit_tool (For example: we want to integrate
+with other systems, or run tests on real hardware), we can
+include KUnit in any kernel, read out results, and parse manually.
+
+.. note:: KUnit is not designed for use in a production system. It is
+ possible that tests may reduce the stability or security of
+ the system.
+
+Configure the Kernel
+====================
+
+KUnit tests can run without kunit_tool. This can be useful, if:
+
+- We have an existing kernel configuration to test.
+- Need to run on real hardware (or using an emulator/VM kunit_tool
+ does not support).
+- Wish to integrate with some existing testing systems.
+
+KUnit is configured with the ``CONFIG_KUNIT`` option, and individual
+tests can also be built by enabling their config options in our
+``.config``. KUnit tests usually (but don't always) have config options
+ending in ``_KUNIT_TEST``. Most tests can either be built as a module,
+or be built into the kernel.
+
+.. note ::
+
+ We can enable the ``KUNIT_ALL_TESTS`` config option to
+ automatically enable all tests with satisfied dependencies. This is
+ a good way of quickly testing everything applicable to the current
+ config.
+
+Once we have built our kernel (and/or modules), it is simple to run
+the tests. If the tests are built-in, they will run automatically on the
+kernel boot. The results will be written to the kernel log (``dmesg``)
+in TAP format.
+
+If the tests are built as modules, they will run when the module is
+loaded.
+
+.. code-block :: bash
+
+ # modprobe example-test
+
+The results will appear in TAP format in ``dmesg``.
+
+.. 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.

+=========================
+Run Tests with kunit_tool
+=========================
+
+We can either run KUnit tests using kunit_tool or can run tests
+manually, and then use kunit_tool to parse the results. To run tests
+manually, see: Documentation/dev-tools/kunit/run_manual.rst.
+As long as we can build the kernel, we can run KUnit.
+
+kunit_tool is a Python script which configures and builds a kernel, runs
+tests, and formats the test results.
+
+Run command:
+
+.. code-block::
+
+ ./tools/testing/kunit/kunit.py run
+
+We should see the following:
+
+.. code-block::
+
+ Generating .config...
+ Building KUnit kernel...
+ Starting KUnit kernel...
+
+We may want to use the following options:
+
+.. code-block::
+
+ ./tools/testing/kunit/kunit.py run --timeout=30 --jobs=`nproc --all
+
+- ``--timeout`` sets a maximum amount of time for tests to run.
+- ``--jobs`` sets the number of threads to build the kernel.
+
+kunit_tool will generate a ``.kunitconfig`` with a default
+configuration, if no other ``.kunitconfig`` file exists
+(in the build directory). In addition, it verifies that the
+generated ``.config`` file contains the ``CONFIG`` options in the
+``.kunitconfig``.
+It is also possible to pass a separate ``.kunitconfig`` fragment to
+kunit_tool. This is useful if we have several different groups of
+tests we want to run independently, or if we want to use pre-defined
+test configs for certain subsystems.
+
+To use a different ``.kunitconfig`` file (such as one
+provided to test a particular subsystem), pass it as an option:
+
+.. code-block::
+
+ ./tools/testing/kunit/kunit.py run --kunitconfig=fs/ext4/.kunitconfig
+
+To view kunit_tool flags (optional command-line arguments), run:
+
+.. code-block::
+
+ ./tools/testing/kunit/kunit.py run --help
+
+Create a ``.kunitconfig`` File
+===============================
+
+If we want to run a specific set of tests (rather than those listed
+in the KUnit ``defconfig``), we can provide Kconfig options in the
+``.kunitconfig`` file. For default .kunitconfig, see:
+https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/testing/kunit/configs/default.config.
+A ``.kunitconfig`` is a ``minconfig`` (a .config
+generated by running ``make savedefconfig``), used for running a
+specific set of tests. This file contains the regular Kernel configs
+with specific test targets. The ``.kunitconfig`` also
+contains any other config options required by the tests (For example:
+dependencies for features under tests, configs that enable/disable
+certain code blocks, arch configs and so on).
+
+To create a ``.kunitconfig``, using the KUnit ``defconfig``:
+
+.. code-block::
+
+ cd $PATH_TO_LINUX_REPO
+ cp tools/testing/kunit/configs/default.config .kunit/.kunitconfig
+
+We can then add any other Kconfig options. For example:
+
+.. code-block::
+
+ CONFIG_LIST_KUNIT_TEST=y
+
+kunit_tool ensures that all config options in ``.kunitconfig`` are
+set in the kernel ``.config`` before running the tests. It warns if we
+have not included the options dependencies.
+
+.. note:: Removing something from the ``.kunitconfig`` will
+ not rebuild the ``.config file``. The configuration is only
+ updated if the ``.kunitconfig`` is not a subset of ``.config``.
+ This means that we can use other tools
+ (For example: ``make menuconfig``) to adjust other config options.
+ The build dir needs to be set for ``make menuconfig`` to
+ work, therefore by default use ``make O=.kunit menuconfig``.
+
+Configure, Build, and Run Tests
+===============================
+
+If we want to make manual changes to the KUnit build process, we
+can run part of the KUnit build process independently.
+When running kunit_tool, from a ``.kunitconfig``, we can generate a
+``.config`` by using the ``config`` argument:
+
+.. code-block::
+
+ ./tools/testing/kunit/kunit.py config
+
+To build a KUnit kernel from the current ``.config``, we can use the
+``build`` argument:
+
+.. code-block::
+
+ ./tools/testing/kunit/kunit.py build
+
+If we already have built UML kernel with built-in KUnit tests, we
+can run the kernel, and display the test results with the ``exec``
+argument:
+
+.. code-block::
+
+ ./tools/testing/kunit/kunit.py exec
+
+The ``run`` command discussed in section: **Run Tests with kunit_tool**,
+is equivalent to running the above three commands in sequence.
+
+Parse Test Results
+==================
+
+KUnit tests output displays results in TAP (Test Anything Protocol)
+format. When running tests, kunit_tool parses this output and prints
+a summary. To see the raw test results in TAP format, we can pass the
+``--raw_output`` argument:
+
+.. code-block::
+
+ ./tools/testing/kunit/kunit.py run --raw_output
+
+If we have KUnit results in the raw TAP format, we can parse them and
+print the human-readable summary with the ``parse`` command for
+kunit_tool. This accepts a filename for an argument, or will read from
+standard input.
+
+.. code-block:: bash
+
+ # Reading from a file
+ ./tools/testing/kunit/kunit.py parse /var/log/dmesg
+ # Reading from stdin
+ dmesg | ./tools/testing/kunit/kunit.py parse
+
+Run Selected Test Suites
+========================
+
+By passing a bash style glob filter to the ``exec`` or ``run``
+commands, we can run a subset of the tests built into a kernel . For
+example: if we only want to run KUnit resource tests, use:
+
+.. code-block::
+
+ ./tools/testing/kunit/kunit.py run 'kunit-resource*'
+
+This uses the standard glob format with wildcard characters.
+
+Run Tests on qemu
+=================
+
+kunit_tool supports running tests on qemu as well as
+via UML. To run tests on qemu, by default it requires two flags:
+
+- ``--arch``: Selects a configs collection (Kconfig, qemu config options
+ and so on), that allow KUnit tests to be run on the specified
+ architecture in a minimal way. The architecture argument is same as
+ the option name passed to the ``ARCH`` variable used by Kbuild.
+ Not all architectures currently support this flag, but we can use
+ ``--qemu_config`` to handle it. If ``um`` is passed (or this flag
+ is ignored), the tests will run via UML. Non-UML architectures,
+ for example: i386, x86_64, arm and so on; run on qemu.
+
+- ``--cross_compile``: Specifies the Kbuild toolchain. It passes the
+ same argument as passed to the ``CROSS_COMPILE`` variable used by
+ Kbuild. As a reminder, this will be the prefix for the toolchain
+ binaries such as GCC. For example:
+
+ - ``sparc64-linux-gnu`` if we have the sparc toolchain installed on
+ our system.
+
+ - ``$HOME/toolchains/microblaze/gcc-9.2.0-nolibc/microblaze-linux/bin/microblaze-linux``
+ if we have downloaded the microblaze toolchain from the 0-day
+ website to a directory in our home directory called toolchains.
+
+If we want to run KUnit tests on an architecture not supported by
+the ``--arch`` flag, or want to run KUnit tests on qemu using a
+non-default configuration; then we can write our own``QemuConfig``.
+These ``QemuConfigs`` are written in Python. They have an import line
+``from..qemu_config import QemuArchParams`` at the top of the file.
+The file must contain a variable called ``QEMU_ARCH`` that has an
+instance of ``QemuArchParams`` assigned to it. See example in:
+``tools/testing/kunit/qemu_configs/x86_64.py``.
+
+Once we have a ``QemuConfig``, we can pass it into kunit_tool,
+using the ``--qemu_config`` flag. When used, this flag replaces the
+``--arch`` flag. For example: using
+``tools/testing/kunit/qemu_configs/x86_64.py``, the invocation appear
+as
+
+.. code-block:: bash
+
+ ./tools/testing/kunit/kunit.py run \
+ --timeout=60 \
+ --jobs=12 \
+ --qemu_config=./tools/testing/kunit/qemu_configs/x86_64.py
+
+To run existing KUnit tests on non-UML architectures, see:
+Documentation/dev-tools/kunit/non_uml.rst.
+
+Command-Line Arguments
+======================
+
+kunit_tool has a number of other command-line arguments which can
+be useful for our test environment. Below the most commonly used
+command line arguments:
+
+- ``--help``: Lists all available options. To list common options,
+ place ``--help`` before the command. To list options specific to that
+ command, place ``--help`` after the command.
+
+ .. note:: Different commands (``config``, ``build``, ``run``, etc)
+ have different supported options.
+- ``--build_dir``: Specifies kunit_tool build directory. It includes
+ the ``.kunitconfig``, ``.config`` files and compiled kernel.
+
+- ``--make_options``: Specifies additional options to pass to make, when
+ compiling a kernel (using ``build`` or ``run`` commands). For example:
+ to enable compiler warnings, we can pass ``--make_options W=1``.
+
+- ``--alltests``: Builds a UML kernel with all config options enabled
+ using ``make allyesconfig``. This allows us to run as many tests as
+ possible.
+
+ .. note:: It is slow and prone to breakage as new options are
+ added or modified. Instead, enable all tests
+ which have satisfied dependencies by adding
+ ``CONFIG_KUNIT_ALL_TESTS=y`` to your ``.kunitconfig``.

+
+Creating a ``.kunitconfig``
+---------------------------
+
+By default, kunit_tool runs a selection of tests. However, you can specify which
+unit tests to run by creating a ``.kunitconfig`` file with kernel config options
+that enable only a specific set of tests and their dependencies.
+The ``.kunitconfig`` file contains a list of kconfig options which are required
+to run the desired targets. The ``.kunitconfig`` also contains any other test
+specific config options, such as test dependencies. For example: the
+``FAT_FS`` tests - ``FAT_KUNIT_TEST``, depends on
+``FAT_FS``. ``FAT_FS`` can be enabled by selecting either ``MSDOS_FS``
+or ``VFAT_FS``. To run ``FAT_KUNIT_TEST``, the ``.kunitconfig`` has:
-Creating a .kunitconfig
------------------------
-If you want to run a specific set of tests (rather than those listed in the
-KUnit defconfig), you can provide Kconfig options in the ``.kunitconfig`` file.
-This file essentially contains the regular Kernel config, with the specific
-test targets as well. The ``.kunitconfig`` should also contain any other config
-options required by the tests.
+.. code-block:: none
+
+ CONFIG_KUNIT=y
+ CONFIG_MSDOS_FS=y
+ CONFIG_FAT_KUNIT_TEST=y
-A good starting point for a ``.kunitconfig`` is the KUnit defconfig:
+1. A good starting point for the ``.kunitconfig``, is the KUnit default
+ config. Run the command:
.. code-block:: bash
cd $PATH_TO_LINUX_REPO
cp tools/testing/kunit/configs/default.config .kunitconfig
-You can then add any other Kconfig options you wish, e.g.:
+.. note ::
+ You may want to remove CONFIG_KUNIT_ALL_TESTS from the ``.kunitconfig`` as
+ it will enable a number of additional tests that you may not want.
+
+2. You can then add any other Kconfig options, for example:
.. code-block:: none
CONFIG_LIST_KUNIT_TEST=y
-:doc:`kunit_tool <kunit-tool>` will ensure that all config options set in
-``.kunitconfig`` are set in the kernel ``.config`` before running the tests.
-It'll warn you if you haven't included the dependencies of the options you're
-using.
+Before running the tests, kunit_tool ensures that all config options
+set in ``.kunitconfig`` are set in the kernel ``.config``. It will warn
+you if you have not included dependencies for the options used.
-.. note::
- Note that removing something from the ``.kunitconfig`` will not trigger a
- rebuild of the ``.config`` file: the configuration is only updated if the
- ``.kunitconfig`` is not a subset of ``.config``. This means that you can use
- other tools (such as make menuconfig) to adjust other config options.
+.. note ::
+ If you change the ``.kunitconfig``, kunit.py will trigger a rebuild of the
+ ``.config`` file. But you can edit the ``.config`` file directly or with

-Using KUnit
-===========

-This document is organized into two main sections: Testing and Common Patterns.

-What is KUnit?
---------------
-
-"K" is short for "kernel" so "KUnit" is the "(Linux) Kernel Unit Testing
-Framework." KUnit is intended first and foremost for writing unit tests; it is
-general enough that it can be used to write integration tests; however, this is
-a secondary goal. KUnit has no ambition of being the only testing framework for
-the kernel; for example, it does not intend to be an end-to-end testing
-framework.
-
-What is Unit Testing?
----------------------
-
-A `unit test <https://martinfowler.com/bliki/UnitTest.html>`_ is a test that
-tests code at the smallest possible scope, a *unit* of code. In the C
-programming language that's a function.
-
-Unit tests should be written for all the publicly exposed functions in a
-compilation unit; so that is all the functions that are exported in either a
-*class* (defined below) or all functions which are **not** static.

Isolating Behavior

+project that does not use a standardized object oriented library (like GNOME's
+GObject) has their own slightly different way of doing object oriented
+programming; the Linux kernel is no exception.
The central concept in kernel object oriented programming is the class. In the
kernel, a *class* is a struct that contains function pointers. This creates a
contract between *implementers* and *users* since it forces them to use the
-same function signature without having to call the function directly. In order
-for it to truly be a class, the function pointers must specify that a pointer

-it possible for the member functions (also known as *methods*) to have access
-to member variables (more commonly known as *fields*) allowing the same
-implementation to have multiple *instances*.
-
-Typically a class can be *overridden* by *child classes* by embedding the
-*parent class* in the child class. Then when a method provided by the child
-class is called, the child implementation knows that the pointer passed to it is
-of a parent contained within the child; because of this, the child can compute
-the pointer to itself because the pointer to the parent is always a fixed offset

-Running existing KUnit tests on non-UML architectures

+Exiting Early on Failed Expectations
+------------------------------------
-There are some special considerations when running existing KUnit tests on
-non-UML architectures:
+We can use ``KUNIT_EXPECT_EQ`` to mark the test as failed and continue
+execution. In some cases, it is unsafe to continue. We can use the
+``KUNIT_ASSERT`` variant to exit on failure.
-* Hardware may not be deterministic, so a test that always passes or fails
- when run under UML may not always do so on real hardware.
-* Hardware and VM environments may not be hermetic. KUnit tries its best to
- provide a hermetic environment to run tests; however, it cannot manage state
- that it doesn't know about outside of the kernel. Consequently, tests that
- may be hermetic on UML may not be hermetic on other architectures.
-* Some features and tooling may not be supported outside of UML.
-* Hardware and VMs are slower than UML.

-entirely possible to support other emulators and even actual hardware, but for

-are supported directly in the KUnit Wrapper via QEMU. Currently, supported
-architectures on QEMU include:
+Allocating Memory

-* i386
-* x86_64
-* arm
-* arm64
-* alpha
-* powerpc
-* riscv
-* s390
-* sparc
+Where you might use ``kzalloc``, you can instead use ``kunit_kzalloc`` as KUnit
+will then ensure that the memory is freed once the test completes.
-In order to run KUnit tests on one of these architectures via QEMU with the
-KUnit wrapper, all you need to do is specify the flags ``--arch`` and
-``--cross_compile`` when invoking the KUnit Wrapper. For example, we could run
-the default KUnit tests on ARM in the following manner (assuming we have an ARM
-toolchain installed):
+This is useful because it lets us use the ``KUNIT_ASSERT_EQ`` macros to exit
+early from a test without having to worry about remembering to call ``kfree``.

-Alternatively, if you want to run your tests on real hardware or in some other

-Kconfig options for the tests you would like to run, and merge them into
-whatever config your are using for your platform. That's it!
+ KUNIT_ASSERT_STREQ(test, buffer, "");
+ }
-For example, let's say you have the following kunitconfig:
-.. code-block:: none
+Testing Static Functions
+------------------------
- CONFIG_KUNIT=y
- CONFIG_KUNIT_EXAMPLE_TEST=y
+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 wanted to run this test on an x86 VM, you might add the following config
-options to your ``.config``:

- CONFIG_KUNIT_EXAMPLE_TEST=y

-All these new options do is enable support for a common serial console needed
-for logging.
+ #ifdef CONFIG_MY_KUNIT_TEST
+ #include "my_kunit_test.c"
+ #endif
-Next, you could build a kernel with these tests as follows:
+Injecting Test-Only Code
+------------------------
+Similar to as shown above, we can add test-specific logic. For example:
-.. code-block:: bash
+.. code-block:: c
- make ARCH=x86 olddefconfig
- make ARCH=x86
+ /* In my_file.h */
-Once you have built a kernel, you could run it on QEMU as follows:
+ #ifdef CONFIG_MY_KUNIT_TEST
+ /* Defined in my_kunit_test.c */
+ void test_only_hook(void);
+ #else
+ void test_only_hook(void) { }
+ #endif
-.. code-block:: bash
+This test-only code can be made more useful by accessing the current ``kunit_test``
+as shown in next section: *Accessing The Current Test*.
- qemu-system-x86_64 -enable-kvm \
- -m 1024 \
- -kernel arch/x86_64/boot/bzImage \
- -append 'console=ttyS0' \
- --nographic
+Accessing The Current Test
+--------------------------
-Interspersed in the kernel logs you might see the following:
+In some cases, we need to call test-only code from outside the test file.
+For example, see example in section *Injecting Test-Only Code* or if
+we are providing a fake implementation of an ops struct. Using
+``kunit_test`` field in ``task_struct``, we can access it via
+``current->kunit_test``.
-.. code-block:: none
+The example below includes how to implement "mocking":
- TAP version 14
- # Subtest: example
- 1..1
- # example_simple_test: initializing
- ok 1 - example_simple_test
- ok 1 - example
+.. code-block:: c
-Congratulations, you just ran a KUnit test on the x86 architecture!
+ #include <linux/sched.h> /* for current */
-In a similar manner, kunit and kunit tests can also be built as modules,
-so if you wanted to run tests in this way you might add the following config
-options to your ``.config``:
+ struct test_data {
+ int foo_result;
+ int want_foo_called_with;
+ };
-.. code-block:: none
+ static int fake_foo(int arg)
+ {
+ struct kunit *test = current->kunit_test;
+ struct test_data *test_data = test->priv;
- CONFIG_KUNIT=m
- CONFIG_KUNIT_EXAMPLE_TEST=m
+ KUNIT_EXPECT_EQ(test, test_data->want_foo_called_with, arg);
+ return test_data->foo_result;
+ }
-Once the kernel is built and installed, a simple
+ static void example_simple_test(struct kunit *test)
+ {
+ /* Assume priv (private, a member used to pass test data from
+ * the init function) is allocated in the suite's .init */
+ struct test_data *test_data = test->priv;
-.. code-block:: bash
+ test_data->foo_result = 42;
+ test_data->want_foo_called_with = 1;
- modprobe example-test
+ /* In a real test, we'd probably pass a pointer to fake_foo somewhere
+ * like an ops struct, etc. instead of calling it directly. */
+ KUNIT_EXPECT_EQ(test, fake_foo(1), 42);
+ }
-...will run the tests.
+In this example, we are using the ``priv`` member of ``struct kunit`` as a way
+of passing data to the test from the init function. In general ``priv`` is
+pointer that can be used for any user data. This is preferred over static
+variables, as it avoids concurrency issues.
-.. note::
- Note that you should make sure your test depends on ``KUNIT=y`` in Kconfig
- if the test does not support module build. Otherwise, it will trigger
- compile errors if ``CONFIG_KUNIT`` is ``m``.
+Had we wanted something more flexible, we could have used a named ``kunit_resource``.
+Each test can have multiple resources which have string names providing the same
+flexibility as a ``priv`` member, but also, for example, allowing helper

-configuration, other people may want to run your tests and may not have access

-does not depend on physical hardware: if some of your test cases don't need the
-hardware, only require the hardware for tests that actually need it.
-
-Now that you have narrowed down exactly what bits are hardware specific, the
-actual procedure for writing and running the tests is pretty much the same as
-writing normal KUnit tests. One special caveat is that you have to reset
-hardware state in between test cases; if this is not possible, you may only be
-able to run one test case per invocation.

- dependent KUnit test.

-KUnit debugfs representation
-============================
-When kunit test suites are initialized, they create an associated directory
-in ``/sys/kernel/debug/kunit/<test-suite>``. The directory contains one file
+ kunit_fail_current_test("data %p is invalid", data);
-- results: "cat results" displays results of each test case and the results
- of the entire suite for the last test run.
+ /* Normal, non-KUnit, error reporting code here. */
+ }
+ #else
+ static void my_debug_function(void) { }
+ #endif
-The debugfs representation is primarily of use when kunit test suites are
-run in a native environment, either as modules or builtin. Having a way
-to display results like this is valuable as otherwise results can be
-intermixed with other events in dmesg output. The maximum size of each
-results file is KUNIT_LOG_SIZE bytes (defined in ``include/kunit/test.h``).

-Required properties:
-- compatible: Should contain one of the following:
- - "nvidia,tegra186-pmc": for Tegra186
- - "nvidia,tegra194-pmc": for Tegra194
- - "nvidia,tegra234-pmc": for Tegra234
-- reg: Must contain an (offset, length) pair of the register set for each
- entry in reg-names.
-- reg-names: Must include the following entries:
- - "pmc"
- - "wake"
- - "aotag"
- - "scratch"
- - "misc" (Only for Tegra194 and later)
-
-Optional properties:
-- nvidia,invert-interrupt: If present, inverts the PMU interrupt signal.
-- 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 2.
-
-Example:
-
-SoC DTSI:
-
- pmc@c3600000 {
- compatible = "nvidia,tegra186-pmc";
- reg = <0 0x0c360000 0 0x10000>,

- <0 0x0c390000 0 0x10000>;
- reg-names = "pmc", "wake", "aotag", "scratch";
- };
-
-Board DTS:
-
- pmc@c360000 {
- nvidia,invert-interrupt;
- };
-
-== Pad Control ==
-
-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. 3.3 V and
-1.8 V signaling voltages are supported on pins where software
-controllable signaling voltage switching is available.
-
-Pad configurations are described with pin configuration nodes which
-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 following pads are present on Tegra186:
-csia csib dsi mipi-bias
-pex-clk-bias pex-clk3 pex-clk2 pex-clk1
-usb0 usb1 usb2 usb-bias
-uart audio hsic dbg
-hdmi-dp0 hdmi-dp1 pex-cntrl sdmmc2-hv
-sdmmc4 cam dsib dsic
-dsid csic csid csie
-dsif spi ufs dmic-hv
-edp sdmmc1-hv sdmmc3-hv conn
-audio-hv ao-hv
-
-Required pin configuration properties:
- - pins: A list of strings, each of which contains the name of a pad
- to be configured.
-
-Optional pin configuration properties:
- - low-power-enable: Configure the pad into power down mode
- - low-power-disable: Configure the pad into active mode
- - power-source: Must contain either TEGRA_IO_PAD_VOLTAGE_1V8 or
- TEGRA_IO_PAD_VOLTAGE_3V3 to select between signaling voltages.
- The values are defined in
- include/dt-bindings/pinctrl/pinctrl-tegra-io-pad.h.
-
-Note: The power state can be configured on all of the above pads except
- for ao-hv. Following pads have software configurable signaling
- voltages: sdmmc2-hv, dmic-hv, sdmmc1-hv, sdmmc3-hv, audio-hv,
- ao-hv.
-
-Pad configuration state example:
- pmc: pmc@7000e400 {
- compatible = "nvidia,tegra186-pmc";
- reg = <0 0x0c360000 0 0x10000>,
- <0 0x0c370000 0 0x10000>,
- <0 0x0c380000 0 0x10000>,
- <0 0x0c390000 0 0x10000>;
- reg-names = "pmc", "wake", "aotag", "scratch";
-
- ...
-
- sdmmc1_3v3: sdmmc1-3v3 {
- pins = "sdmmc1-hv";
- power-source = <TEGRA_IO_PAD_VOLTAGE_3V3>;
- };
-
- sdmmc1_1v8: sdmmc1-1v8 {
- pins = "sdmmc1-hv";
- power-source = <TEGRA_IO_PAD_VOLTAGE_1V8>;
- };
-

- pins = "hdmi";
- low-power-enable;
- }
-
- hdmi_on: hdmi-on {
- pins = "hdmi";
- low-power-disable;

- };
-
-Pinctrl client example:
- sdmmc1: sdhci@3400000 {
- ...
- pinctrl-names = "sdmmc-3v3", "sdmmc-1v8";
- pinctrl-0 = <&sdmmc1_3v3>;

+ These are pad configuration nodes. 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. 3.3 V and
+ 1.8 V signaling voltages are supported on pins where software
+ controllable signaling voltage switching is available.
+
+ Pad configurations are described with pin configuration nodes
+ which 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

+ determine which peripherals are available to it and the range over which

-* Samsung Exynos5260 Clock Controller
-
-Exynos5260 has 13 clock controllers which are instantiated
-independently from the device-tree. These clock controllers
-generate and supply clocks to various hardware blocks within
-the SoC.
-
-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
-dt-bindings/clock/exynos5260-clk.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 from XXTI
- - "xrtcxti" - input clock from XRTCXTI
- - "ioclk_pcm_extclk" - pcm external operation clock
- - "ioclk_spdif_extclk" - spdif external operation clock
- - "ioclk_i2s_cdclk" - i2s0 codec clock
-
-Phy clocks:
-
-There are several clocks which are generated by specific PHYs.
-These clocks are fed into the clock controller and then routed to
-the hardware blocks. These clocks are defined as fixed clocks in the
-driver with following names:
-
- - "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3
- - "phyclk_dptx_phy_ch2_txd_clk" - dp phy clock for channel 2
- - "phyclk_dptx_phy_ch1_txd_clk" - dp phy clock for channel 1
- - "phyclk_dptx_phy_ch0_txd_clk" - dp phy clock for channel 0
- - "phyclk_hdmi_phy_tmds_clko" - hdmi phy tmds clock
- - "phyclk_hdmi_phy_pixel_clko" - hdmi phy pixel clock
- - "phyclk_hdmi_link_o_tmds_clkhi" - hdmi phy for hdmi link
- - "phyclk_dptx_phy_o_ref_clk_24m" - dp phy reference clock
- - "phyclk_dptx_phy_clk_div2"
- - "phyclk_mipi_dphy_4l_m_rxclkesc0"
- - "phyclk_usbhost20_phy_phyclock" - usb 2.0 phy clock
- - "phyclk_usbhost20_phy_freeclk"
- - "phyclk_usbhost20_phy_clk48mohci"
- - "phyclk_usbdrd30_udrd30_pipe_pclk"
- - "phyclk_usbdrd30_udrd30_phyclock" - usb 3.0 phy clock
-

-* Samsung Exynos7 Clock Controller
-
-Exynos7 clock controller has various blocks which are instantiated
-independently from the device-tree. These clock controllers
-generate and supply clocks to various hardware blocks within
-the SoC.
-
-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
-dt-bindings/clock/exynos7-clk.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 from XXTI
-
-Required Properties for Clock Controller:
-
- - compatible: clock controllers will use one of the following
- compatible strings to indicate the clock controller
- functionality.
-
- - "samsung,exynos7-clock-topc"
- - "samsung,exynos7-clock-top0"
- - "samsung,exynos7-clock-top1"

+description: |
+ Expected external clocks, defined in DTS as fixed-rate clocks with a matching
+ name::
+ - "fin_pll" - PLL input clock from XXTI
+ - "xrtcxti" - input clock from XRTCXTI
+ - "ioclk_pcm_extclk" - pcm external operation clock
+ - "ioclk_spdif_extclk" - spdif external operation clock
+ - "ioclk_i2s_cdclk" - i2s0 codec clock
+
+ Phy clocks::
+ There are several clocks which are generated by specific PHYs. These clocks
+ are fed into the clock controller and then routed to the hardware blocks.
+ These clocks are defined as fixed clocks in the driver with following names::
+ - "phyclk_dptx_phy_ch3_txd_clk" - dp phy clock for channel 3
+ - "phyclk_dptx_phy_ch2_txd_clk" - dp phy clock for channel 2
+ - "phyclk_dptx_phy_ch1_txd_clk" - dp phy clock for channel 1
+ - "phyclk_dptx_phy_ch0_txd_clk" - dp phy clock for channel 0
+ - "phyclk_hdmi_phy_tmds_clko" - hdmi phy tmds clock
+ - "phyclk_hdmi_phy_pixel_clko" - hdmi phy pixel clock
+ - "phyclk_hdmi_link_o_tmds_clkhi" - hdmi phy for hdmi link
+ - "phyclk_dptx_phy_o_ref_clk_24m" - dp phy reference clock
+ - "phyclk_dptx_phy_clk_div2"
+ - "phyclk_mipi_dphy_4l_m_rxclkesc0"

+ - "phyclk_usbdrd30_udrd30_pipe_pclk"
+ - "phyclk_usbdrd30_udrd30_phyclock" - usb 3.0 phy clock
+
+ All available clocks are defined as preprocessor macros in
+ include/dt-bindings/clock/exynos5260-clk.h header.

+description: |
+ Exynos7885 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 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/exynos7885.h' header.

-* Samsung S5P6442/S5PC110/S5PV210 Clock Controller
-
-Samsung S5P6442, S5PC110 and S5PV210 SoCs contain integrated clock
-controller, which generates and supplies clock to various controllers
-within the SoC.
-
-Required Properties:
-
-- compatible: should be one of following:
- - "samsung,s5pv210-clock" : for clock controller of Samsung
- S5PC110/S5PV210 SoCs,
- - "samsung,s5p6442-clock" : for clock controller of Samsung
- S5P6442 SoC.
-
-- reg: physical base address of the controller and length of memory mapped
- region.
-
-- #clock-cells: should be 1.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/s5pv210.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:
- - "xxti": external crystal oscillator connected to XXTI and XXTO pins of
-the SoC,
- - "xusbxti": external crystal oscillator connected to XUSBXTI and XUSBXTO
-pins of the SoC,
-
-A subset of above clocks available on given board shall be specified in
-board device tree, including the system base clock, as selected by XOM[0]
-pin of the SoC. Refer to generic fixed rate clock bindings
-documentation[1] for more information how to specify these clocks.
-
-[1] Documentation/devicetree/bindings/clock/fixed-clock.yaml
-
-Example: Clock controller node:
-
- clock: clock-controller@7e00f000 {
- compatible = "samsung,s5pv210-clock";
- reg = <0x7e00f000 0x1000>;
- #clock-cells = <1>;
- };
-
-Example: Required external clocks:
-
- xxti: clock-xxti {
- compatible = "fixed-clock";
- clock-output-names = "xxti";
- clock-frequency = <24000000>;
- #clock-cells = <0>;
- };
-
- xusbxti: clock-xusbxti {
- compatible = "fixed-clock";
- clock-output-names = "xusbxti";
- clock-frequency = <24000000>;
- #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@e2900000 {
- compatible = "samsung,s5pv210-uart";
- reg = <0xe2900000 0x400>;
- interrupt-parent = <&vic1>;
- interrupts = <10>;
- clock-names = "uart", "clk_uart_baud0",
- "clk_uart_baud1";
- clocks = <&clocks UART0>, <&clocks UART0>,
- <&clocks SCLK_UART0>;
- };

+description: |
+ The Unisoc DRM master device is a virtual device needed to list all
+ DPU devices or other display interface nodes that comprise the
+ graphics subsystem.
+
+ Unisoc's display pipeline have several components as below description,
+ multi display controllers and corresponding physical interfaces.
+ For different display scenarios, dpu0 and dpu1 maybe binding to different
+ encoder.
+
+ E.g:
+ dpu0 and dpu1 both binding to DSI for dual mipi-dsi display;
+ dpu0 binding to DSI for primary display, and dpu1 binding to DP for external display;

-NVIDIA Tegra Boot and Power Management Processor (BPMP)
-
-The BPMP is a specific processor in Tegra chip, which is designed for
-booting process handling and offloading the power management, clock
-management, and reset control tasks from the CPU. The binding document
-defines the resources that would be used by the BPMP firmware driver,
-which can create the interprocessor communication (IPC) between the CPU
-and BPMP.
-
-Required properties:
-- compatible
- Array of strings
- One of:
- - "nvidia,tegra186-bpmp"
-- mboxes : The phandle of mailbox controller and the mailbox specifier.
-- shmem : List of the phandle of the TX and RX shared memory area that
- the IPC between CPU and BPMP is based on.
-- #clock-cells : Should be 1.
-- #power-domain-cells : Should be 1.
-- #reset-cells : Should be 1.
-
-This node is a mailbox consumer. See the following files for details of
-the mailbox subsystem, and the specifiers implemented by the relevant
-provider(s):
-
-- .../mailbox/mailbox.txt
-- .../mailbox/nvidia,tegra186-hsp.txt
-
-This node is a clock, power domain, and reset provider. See the following
-files for general documentation of those features, and the specifiers
-implemented by this node:
-
-- .../clock/clock-bindings.txt
-- <dt-bindings/clock/tegra186-clock.h>
-- ../power/power-domain.yaml
-- <dt-bindings/power/tegra186-powergate.h>
-- .../reset/reset.txt
-- <dt-bindings/reset/tegra186-reset.h>
-
-The BPMP implements some services which must be represented by separate nodes.
-For example, it can provide access to certain I2C controllers, and the I2C
-bindings represent each I2C controller as a device tree node. Such nodes should
-be nested directly inside the main BPMP node.
-
-Software can determine whether a child node of the BPMP node represents a device
-by checking for a compatible property. Any node with a compatible property
-represents a device that can be instantiated. Nodes without a compatible
-property may be used to provide configuration information regarding the BPMP
-itself, although no such configuration nodes are currently defined by this
-binding.
-
-The BPMP firmware defines no single global name-/numbering-space for such
-services. Put another way, the numbering scheme for I2C buses is distinct from
-the numbering scheme for any other service the BPMP may provide (e.g. a future
-hypothetical SPI bus service). As such, child device nodes will have no reg
-property, and the BPMP node will have no #address-cells or #size-cells property.
-
-The shared memory bindings for BPMP
------------------------------------
-
-The shared memory area for the IPC TX and RX between CPU and BPMP are
-predefined and work on top of sysram, which is an SRAM inside the chip.
-
-See ".../sram/sram.txt" for the bindings.
-
-Example:
-
-hsp_top0: hsp@3c00000 {
- ...
- #mbox-cells = <2>;

-NVIDIA Tegra20/Tegra30/Tegr114/Tegra124 fuse block.
-
-Required properties:
-- compatible : For Tegra20, must contain "nvidia,tegra20-efuse". For Tegra30,
- must contain "nvidia,tegra30-efuse". For Tegra114, must contain
- "nvidia,tegra114-efuse". For Tegra124, must contain "nvidia,tegra124-efuse".
- For Tegra132 must contain "nvidia,tegra132-efuse", "nvidia,tegra124-efuse".
- For Tegra210 must contain "nvidia,tegra210-efuse". For Tegra186 must contain
- "nvidia,tegra186-efuse". For Tegra194 must contain "nvidia,tegra194-efuse".
- For Tegra234 must contain "nvidia,tegra234-efuse".
- Details:
- nvidia,tegra20-efuse: Tegra20 requires using APB DMA to read the fuse data
- due to a hardware bug. Tegra20 also lacks certain information which is
- available in later generations such as fab code, lot code, wafer id,..
- nvidia,tegra30-efuse, nvidia,tegra114-efuse and nvidia,tegra124-efuse:
- The differences between these SoCs are the size of the efuse array,
- the location of the spare (OEM programmable) bits and the location of
- the speedo data.
-- reg: Should contain 1 entry: the entry gives the physical address and length
- of the fuse registers.
-- 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:
- - 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:
- - fuse

-
-Required properties:
-
-- compatible:
- Must be "brcm,brcmstb-gpio"
-
-- reg:
- Define the base and range of the I/O address space containing
- the brcmstb GPIO controller registers
-
-- #gpio-cells:
- Should be <2>. The first cell is the pin number (within the controller's

-
-- gpio-controller:
- Specifies that the node is a GPIO controller.
-
-- brcm,gpio-bank-widths:
- Number of GPIO lines for each bank. Number of elements must

-
-Optional properties:
-
-- interrupts:
- The interrupt shared by all GPIO lines for this controller.
-
-- interrupts-extended:
- Alternate form of specifying interrupts and parents that allows for
- multiple parents. This takes precedence over 'interrupts' and
- 'interrupt-parent'. Wakeup-capable GPIO controllers often route their
- wakeup interrupt lines through a different interrupt controller than the
- primary interrupt line, making this property necessary.
-
-- #interrupt-cells:
- Should be <2>. The first cell is the GPIO number, the second should specify
- flags. The following subset of flags is supported:
- - 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.

-NVIDIA Tegra186 GPIO controllers
-
-Tegra186 contains two GPIO controllers; a main controller and an "AON"
-controller. This binding document applies to both controllers. The register
-layouts for the controllers share many similarities, but also some significant
-differences. Hence, this document describes closely related but different
-bindings and compatible values.
-
-The Tegra186 GPIO controller allows software to set the IO direction of, and
-read/write the value of, numerous GPIO signals. Routing of GPIO signals to
-package balls is under the control of a separate pin controller HW block. Two
-major sets of registers exist:
-
-a) Security registers, which allow configuration of allowed access to the GPIO
-register set. These registers exist in a single contiguous block of physical
-address space. The size of this block, and the security features available,
-varies between the different GPIO controllers.
-
-Access to this set of registers is not necessary in all circumstances. Code
-that wishes to configure access to the GPIO registers needs access to these
-registers to do so. Code which simply wishes to read or write GPIO data does not
-need access to these registers.
-
-b) GPIO registers, which allow manipulation of the GPIO signals. In some GPIO
-controllers, these registers are exposed via multiple "physical aliases" in
-address space, each of which access the same underlying state. See the hardware
-documentation for rationale. Any particular GPIO client is expected to access
-just one of these physical aliases.
-
-Tegra HW documentation describes a unified naming convention for all GPIOs
-implemented by the SoC. Each GPIO is assigned to a port, and a port may control
-a number of GPIOs. Thus, each GPIO is named according to an alphabetical port
-name and an integer GPIO name within the port. For example, GPIO_PA0, GPIO_PN6,
-or GPIO_PCC3.
-
-The number of ports implemented by each GPIO controller varies. The number of
-implemented GPIOs within each port varies. GPIO registers within a controller
-are grouped and laid out according to the port they affect.
-
-The mapping from port name to the GPIO controller that implements that port, and
-the mapping from port name to register offset within a controller, are both
-extremely non-linear. The header file <dt-bindings/gpio/tegra186-gpio.h>
-describes the port-level mapping. In that file, the naming convention for ports
-matches the HW documentation. The values chosen for the names are alphabetically
-sorted within a particular controller. Drivers need to map between the DT GPIO
-IDs and HW register offsets using a lookup table.
-
-Each GPIO controller can generate a number of interrupt signals. Each signal
-represents the aggregate status for all GPIOs within a set of ports. Thus, the
-number of interrupt signals generated by a controller varies as a rough function
-of the number of ports it implements. Note that the HW documentation refers to
-both the overall controller HW module and the sets-of-ports as "controllers".
-
-Each GPIO controller in fact generates multiple interrupts signals for each set
-of ports. Each GPIO may be configured to feed into a specific one of the
-interrupt signals generated by a set-of-ports. The intent is for each generated
-signal to be routed to a different CPU, thus allowing different CPUs to each
-handle subsets of the interrupts within a port. The status of each of these
-per-port-set signals is reported via a separate register. Thus, a driver needs
-to know which status register to observe. This binding currently defines no
-configuration mechanism for this. By default, drivers should use register
-GPIO_${port}_INTERRUPT_STATUS_G1_0. Future revisions to the binding could
-define a property to configure this.
-
-Required properties:
-- compatible
- Array of strings.
- One of:
- - "nvidia,tegra186-gpio".
- - "nvidia,tegra186-gpio-aon".
- - "nvidia,tegra194-gpio".
- - "nvidia,tegra194-gpio-aon".
-- reg-names
- Array of strings.
- Contains a list of names for the register spaces described by the reg
- property. May contain the following entries, in any order:
- - "gpio": Mandatory. GPIO control registers. This may cover either:
- a) The single physical alias that this OS should use.
- b) All physical aliases that exist in the controller. This is
- appropriate when the OS is responsible for managing assignment of
- the physical aliases.
- - "security": Optional. Security configuration registers.
- Users of this binding MUST look up entries in the reg property by name,
- using this reg-names property to do so.
-- reg
- Array of (physical base address, length) tuples.
- Must contain one entry per entry in the reg-names property, in a matching
- order.
-- interrupts
- Array of interrupt specifiers.
- The interrupt outputs from the HW block, one per set of ports, in the
- order the HW manual describes them. The number of entries required varies
- depending on compatible value:
- - "nvidia,tegra186-gpio": 6 entries.
- - "nvidia,tegra186-gpio-aon": 1 entry.
- - "nvidia,tegra194-gpio": 6 entries.
- - "nvidia,tegra194-gpio-aon": 1 entry.
-- gpio-controller
- Boolean.
- Marks the device node as a GPIO controller/provider.
-- #gpio-cells
- Single-cell integer.
- Must be <2>.
- Indicates how many cells are used in a consumer's GPIO specifier.
- In the specifier:
- - The first cell is the pin number.
- See <dt-bindings/gpio/tegra186-gpio.h>.
- - The second cell contains flags:
- - Bit 0 specifies polarity
- - 0: Active-high (normal).
- - 1: Active-low (inverted).
-- interrupt-controller
- Boolean.
- Marks the device node as an interrupt controller/provider.
-- #interrupt-cells
- Single-cell integer.
- Must be <2>.
- Indicates how many cells are used in a consumer's interrupt specifier.
- In the specifier:
- - The first cell is the GPIO number.
- See <dt-bindings/gpio/tegra186-gpio.h>.
- - The second cell is contains flags:
- - Bits [3:0] indicate trigger type and level:
- - 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.

-Pinctrl-based I2C Bus Mux
-
-This binding describes an I2C bus multiplexer that uses pin multiplexing to
-route the I2C signals, and represents the pin multiplexing configuration
-using the pinctrl device tree bindings.

-
-Required properties:
-- compatible: i2c-mux-pinctrl
-- i2c-parent: The phandle of the I2C bus that this multiplexer's master-side
- port is connected to.
-
-Also required are:
-
-* Standard pinctrl properties that specify the pin mux state for each child
- bus. See ../pinctrl/pinctrl-bindings.txt.
-
-* Standard I2C mux properties. See i2c-mux.yaml in this directory.
-
-* I2C child bus nodes. See i2c-mux.yaml in this directory.
-
-For each named state defined in the pinctrl-names property, an I2C child bus
-will be created. I2C child bus numbers are assigned based on the index into
-the pinctrl-names property.
-
-The only exception is that no bus will be created for a state named "idle". If
-such a state is defined, it must be the last entry in pinctrl-names. For
-example:
-
- pinctrl-names = "ddc", "pta", "idle" -> ddc = bus 0, pta = bus 1
- pinctrl-names = "ddc", "idle", "pta" -> Invalid ("idle" not last)
- pinctrl-names = "idle", "ddc", "pta" -> Invalid ("idle" not last)
-
-Whenever an access is made to a device on a child bus, the relevant pinctrl
-state will be programmed into hardware.
-
-If an idle state is defined, whenever an access is not being made to a device
-on a child bus, the idle pinctrl state will be programmed into hardware.
-
-If an idle state is not defined, the most recently used pinctrl state will be
-left programmed into hardware whenever no access is being made of a device on
-a child bus.
-
-Example:
-
- i2cmux {
- compatible = "i2c-mux-pinctrl";
- #address-cells = <1>;
- #size-cells = <0>;
-
- i2c-parent = <&i2c1>;
-
- pinctrl-names = "ddc", "pta", "idle";
- pinctrl-0 = <&state_i2cmux_ddc>;
- pinctrl-1 = <&state_i2cmux_pta>;
- pinctrl-2 = <&state_i2cmux_idle>;
-
- i2c@0 {
- reg = <0>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- eeprom {
- compatible = "eeprom";
- reg = <0x50>;
- };
- };
-

+ signals, and represents the pin multiplexing configuration using the pinctrl device tree
+ bindings.

+ For each named state defined in the pinctrl-names property, an I2C child bus will be created.
+ I2C child bus numbers are assigned based on the index into the pinctrl-names property.
+
+ The only exception is that no bus will be created for a state named "idle". If such a state is
+ defined, it must be the last entry in pinctrl-names. For example:
+
+ pinctrl-names = "ddc", "pta", "idle" -> ddc = bus 0, pta = bus 1
+ pinctrl-names = "ddc", "idle", "pta" -> Invalid ("idle" not last)
+ pinctrl-names = "idle", "ddc", "pta" -> Invalid ("idle" not last)
+
+ Whenever an access is made to a device on a child bus, the relevant pinctrl state will be
+ programmed into hardware.
+
+ If an idle state is defined, whenever an access is not being made to a device on a child bus,
+ the idle pinctrl state will be programmed into hardware.
+
+ If an idle state is not defined, the most recently used pinctrl state will be left programmed
+ into hardware whenever no access is being made of a device on a child bus.

-
-The BPMP I2C node must be located directly inside the main BPMP node. See
-../firmware/nvidia,tegra186-bpmp.txt for details of the BPMP binding.
-
-This node represents an I2C controller. See ../i2c/i2c.txt for details of the

-NVIDIA Tegra20/Tegra30/Tegra114 I2C controller driver.
-
-Required properties:
-- compatible : For Tegra20, must be one of "nvidia,tegra20-i2c-dvc" or
- "nvidia,tegra20-i2c". For Tegra30, must be "nvidia,tegra30-i2c".
- For Tegra114, must be "nvidia,tegra114-i2c". Otherwise, must be
- "nvidia,<chip>-i2c", plus at least one of the above, where <chip> is
- tegra124, tegra132, or tegra210.
- Details of compatible are as follows:
- nvidia,tegra20-i2c-dvc: Tegra20 has specific I2C controller called as DVC I2C
- controller. This only support master mode of I2C communication. Register
- interface/offset and interrupts handling are different than generic I2C
- controller. Driver of DVC I2C controller is only compatible with
- "nvidia,tegra20-i2c-dvc".
- nvidia,tegra20-i2c: Tegra20 has 4 generic I2C controller. This can support
- master and slave mode of I2C communication. The i2c-tegra driver only
- support master mode of I2C communication. Driver of I2C controller is
- only compatible with "nvidia,tegra20-i2c".
- nvidia,tegra30-i2c: Tegra30 has 5 generic I2C controller. This controller is
- very much similar to Tegra20 I2C controller with additional feature:
- Continue Transfer Support. This feature helps to implement M_NO_START
- as per I2C core API transfer flags. Driver of I2C controller is
- compatible with "nvidia,tegra30-i2c" to enable the continue transfer
- support. This is also compatible with "nvidia,tegra20-i2c" without
- continue transfer support.
- nvidia,tegra114-i2c: Tegra114 has 5 generic I2C controller. This controller is
- very much similar to Tegra30 I2C controller with some hardware
- modification:
- - Tegra30/Tegra20 I2C controller has 2 clock source called div-clk and
- fast-clk. Tegra114 has only one clock source called as div-clk and
- hence clock mechanism is changed in I2C controller.
- - Tegra30/Tegra20 I2C controller has enabled per packet transfer by
- default and there is no way to disable it. Tegra114 has this
- interrupt disable by default and SW need to enable explicitly.
- Due to above changes, Tegra114 I2C driver makes incompatible with
- previous hardware driver. Hence, tegra114 I2C controller is compatible
- with "nvidia,tegra114-i2c".
- nvidia,tegra210-i2c-vi: Tegra210 has one I2C controller that is on host1x bus
- and is part of VE power domain and typically used for camera use-cases.
- This VI I2C controller is mostly compatible with the programming model
- of the regular I2C controllers with a few exceptions. The I2C registers
- start at an offset of 0xc00 (instead of 0), registers are 16 bytes
- apart (rather than 4) and the controller does not support slave mode.
-- reg: Should contain I2C controller registers physical address and length.
-- interrupts: Should contain I2C controller interrupts.
-- address-cells: Address cells for I2C device address.
-- size-cells: Size of the I2C device address.
-- 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:
- Tegra20/Tegra30:
- - div-clk
- - fast-clk
- Tegra114:
- - div-clk
- Tegra210:
- - div-clk
- - slow (only for nvidia,tegra210-i2c-vi compatible node)
-- resets: Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names: Must include the following entries:
- - i2c
-- power-domains: Only for nvidia,tegra210-i2c-vi compatible node and must
- include venc powergate node as vi i2c is part of VE power domain.
- tegra210-i2c-vi:
- - pd_venc
-- dmas: Must contain an entry for each entry in clock-names.
- See ../dma/dma.txt for details.
-- dma-names: Must include the following entries:
- - rx
- - tx
-
-Example:
-
- i2c@7000c000 {

-* PWM vibrator device tree bindings
-
-Registers a PWM device as vibrator. It is expected, that the vibrator's
-strength increases based on the duty cycle of the enable PWM channel
-(100% duty cycle meaning strongest vibration, 0% meaning no vibration).
-
-The binding supports an optional direction PWM channel, that can be
-driven at fixed duty cycle. If available this is can be used to increase
-the vibration effect of some devices.
-
-Required properties:
-- compatible: should contain "pwm-vibrator"

-- pwms: Should contain a PWM handle for each entry in pwm-names
-
-Optional properties:
-- vcc-supply: Phandle for the regulator supplying power

-LEDs connected to Broadcom BCM6328 controller
-
-This controller is present on BCM6318, BCM6328, BCM6362 and BCM63268.
-In these SoCs it's possible to control LEDs both as GPIOs or by hardware.
-However, on some devices there are Serial LEDs (LEDs connected to a 74x164
-controller), which can either be controlled by software (exporting the 74x164
-as spi-gpio. See Documentation/devicetree/bindings/gpio/fairchild,74hc595.yaml),
-or by hardware using this driver.
-Some of these Serial LEDs are hardware controlled (e.g. ethernet LEDs) and
-exporting the 74x164 as spi-gpio prevents those LEDs to be hardware
-controlled, so the only chance to keep them working is by using this driver.
-
-BCM6328 LED controller has a HWDIS register, which controls whether a LED
-should be controlled by a hardware signal instead of the MODE register value,
-with 0 meaning hardware control enabled and 1 hardware control disabled. This
-is usually 1:1 for hardware to LED signals, but through the activity/link
-registers you have some limited control over rerouting the LEDs (as
-explained later in brcm,link-signal-sources). Even if a LED is hardware
-controlled you are still able to make it blink or light it up if it isn't,
-but you can't turn it off if the hardware decides to light it up. For this
-reason, hardware controlled LEDs aren't registered as LED class devices.
-
-Required properties:
- - compatible : should be "brcm,bcm6328-leds".
- - #address-cells : must be 1.
- - #size-cells : must be 0.
- - reg : BCM6328 LED controller address and size.
-
-Optional properties:
- - brcm,serial-leds : Boolean, enables Serial LEDs.
- Default : false
- - brcm,serial-mux : Boolean, enables Serial LEDs multiplexing.
- Default : false
- - brcm,serial-clk-low : Boolean, makes clock signal active low.
- Default : false
- - brcm,serial-dat-low : Boolean, makes data signal active low.
- Default : false
- - brcm,serial-shift-inv : Boolean, inverts Serial LEDs shift direction.
- Default : false
-
-Each LED is represented as a sub-node of the brcm,bcm6328-leds device.
-
-LED sub-node required properties:
- - reg : LED pin number (only LEDs 0 to 23 are valid).
-
-LED sub-node optional properties:
- a) Optional properties for sub-nodes related to software controlled LEDs:
- - label : see Documentation/devicetree/bindings/leds/common.txt
- - active-low : Boolean, makes LED active low.
- Default : false
- - default-state : see
- Documentation/devicetree/bindings/leds/common.txt
- - linux,default-trigger : see
- Documentation/devicetree/bindings/leds/common.txt
-
- b) Optional properties for sub-nodes related to hardware controlled LEDs:
- - brcm,hardware-controlled : Boolean, makes this LED hardware controlled.
- Default : false
- - brcm,link-signal-sources : An array of hardware link
- signal sources. Up to four link hardware signals can get muxed into
- these LEDs. Only valid for LEDs 0 to 7, where LED signals 0 to 3 may
- be muxed to LEDs 0 to 3, and signals 4 to 7 may be muxed to LEDs
- 4 to 7. A signal can be muxed to more than one LED, and one LED can
- have more than one source signal.
- - brcm,activity-signal-sources : An array of hardware activity
- signal sources. Up to four activity hardware signals can get muxed into
- these LEDs. Only valid for LEDs 0 to 7, where LED signals 0 to 3 may
- be muxed to LEDs 0 to 3, and signals 4 to 7 may be muxed to LEDs
- 4 to 7. A signal can be muxed to more than one LED, and one LED can

-NVIDIA Tegra Hardware Synchronization Primitives (HSP)
-
-The HSP modules are used for the processors to share resources and communicate
-together. It provides a set of hardware synchronization primitives for
-interprocessor communication. So the interprocessor communication (IPC)
-protocols can use hardware synchronization primitives, when operating between
-two processors not in an SMP relationship.
-
-The features that HSP supported are shared mailboxes, shared semaphores,
-arbitrated semaphores and doorbells.
-
-Required properties:
-- name : Should be hsp
-- compatible
- Array of strings.
- one of:
- - "nvidia,tegra186-hsp"
- - "nvidia,tegra194-hsp", "nvidia,tegra186-hsp"
-- reg : Offset and length of the register set for the device.
-- interrupt-names
- Array of strings.
- Contains a list of names for the interrupts described by the interrupt
- property. May contain the following entries, in any order:
- - "doorbell"
- - "sharedN", where 'N' is a number from zero up to the number of
- external interrupts supported by the HSP instance minus one.
- Users of this binding MUST look up entries in the interrupt property
- by name, using this interrupt-names property to do so.
-- interrupts
- Array of interrupt specifiers.
- Must contain one entry per entry in the interrupt-names property,
- in a matching order.
-- #mbox-cells : Should be 2.
-
-The mbox specifier of the "mboxes" property in the client node should contain
-two cells. The first cell determines the HSP type and the second cell is used
-to identify the mailbox that the client is going to use.
-
-For doorbells, the second cell specifies the index of the doorbell to use.
-
-For shared mailboxes, the second cell is composed of two fields:
-- bits 31..24:
- A bit mask of flags that further specify how the shared mailbox will be
- used. Valid flags are:
- - bit 31:
- Defines the direction of the mailbox. If set, the mailbox will be used
- as a producer (i.e. used to send data). If cleared, the mailbox is the
- consumer of data sent by a producer.
-
-- bits 23.. 0:
- The index of the shared mailbox to use. The number of available mailboxes
- may vary by instance of the HSP block and SoC generation.

- main I2C ports. Each map has it own I2C address and acts as a standard
- slave device on the I2C bus. The main address is mandatory, others are
- optional and remain at default values if not specified.
-
-Optional Properties:
-
- - interrupt-names: Should specify the interrupts as "intrq1", "intrq2" and/or
- "intrq3". All interrupts are optional. The "intrq3" interrupt
- is only available on the adv7481
- - interrupts: Specify the interrupt lines for the ADV748x
- - reg-names : Names of maps with programmable addresses.
- It shall contain all maps needing a non-default address.
- Possible map names are:
- "main", "dpll", "cp", "hdmi", "edid", "repeater",
- "infoframe", "cbus", "cec", "sdp", "txa", "txb"
-
-The device node must contain 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.
-
- Name Type Port
- ---------------------------------------
- AIN0 sink 0
- AIN1 sink 1
- AIN2 sink 2
- AIN3 sink 3
- AIN4 sink 4
- AIN5 sink 5
- AIN6 sink 6
- AIN7 sink 7
- HDMI sink 8
- TTL sink 9
- TXA source 10
- TXB source 11
-
-The digital output port nodes, when present, shall contain at least one
-endpoint. Each of those endpoints shall contain the data-lanes property as
-described in video-interfaces.txt.
-
-Required source endpoint properties:
- - data-lanes: an array of physical data lane indexes
- The accepted value(s) for this property depends on which of the two
- sources are described. For TXA 1, 2 or 4 data lanes can be described
- while for TXB only 1 data lane is valid. See video-interfaces.txt
- for detailed description.
-
-Ports are optional if they are not connected to anything at the hardware level.
-

+title: Quad GMSL2 to CSI-2 Deserializer with GMSL1 Compatibility
+
+maintainers:
+ - Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>
+
+description: |
+ The MAX96712 deserializer converts GMSL2 or GMSL1 serial inputs into MIPI
+ CSI-2 D-PHY or C-PHY formatted outputs. The device allows each link to
+ simultaneously transmit bidirectional control-channel data while forward
+ video transmissions are in progress. The MAX96712 can accommodate as many as
+ four remotely located sensors using industry-standard coax or STP
+ interconnects.
+
+ Each GMSL2 serial link operates at a fixed rate of 3Gbps or 6Gbps in the
+ forward direction and 187.5Mbps in the reverse direction. In GMSL1 mode, the
+ MAX96712 can be paired with first-generation 3.12Gbps or 1.5Gbps GMSL1
+ serializers or operate up to 3.12Gbps with GMSL2 serializers in GMSL1 mode.

-* ROHM BD9571MWV/BD9574MWF Power Management Integrated Circuit (PMIC) bindings
-
-Required properties:
- - compatible : Should be "rohm,bd9571mwv" or "rohm,bd9574mwf".
- - reg : I2C slave address.
- - 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 IRQ, should be 2.
- The first cell is the IRQ number.
- The second cell is the flags, encoded as trigger
- masks from ../interrupt-controller/interrupts.txt.
- - 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 flags.
- See ../gpio/gpio.txt for more information.
- - regulators: : List of child nodes that specify the regulator
- initialization data. Child nodes must be named
- after their hardware counterparts:
- - vd09
- - vd18
- - vd25
- - vd33
- - dvfs
- Each child node is defined using the standard
- binding for regulators.
-
-Optional properties:
- - rohm,ddr-backup-power : Value to use for DDR-Backup Power (default 0).
- This is a bitmask that specifies which DDR power
- rails need to be kept powered when backup mode is
- entered, for system suspend:
- - bit 0: DDR0
- - bit 1: DDR1
- - bit 2: DDR0C
- - bit 3: DDR1C
- These bits match the KEEPON_DDR* bits in the
- documentation for the "BKUP Mode Cnt" register.
- - rohm,rstbmode-level: The RSTB signal is configured for level mode, to
- accommodate a toggle power switch (the RSTBMODE pin is
- strapped low).
- - rohm,rstbmode-pulse: The RSTB signal is configured for pulse mode, to
- accommodate a momentary power switch (the RSTBMODE pin
- is strapped high).
- The two properties above are mutually exclusive.
-
-Example:
-
- pmic: pmic@30 {

-* ROHM BD70528 Power Management Integrated Circuit bindings
-
-BD70528MWV is an ultra-low quiescent current general purpose, single-chip,
-power management IC for battery-powered portable devices. The IC
-integrates 3 ultra-low current consumption buck converters, 3 LDOs and 2
-LED Drivers. Also included are 4 GPIOs, a real-time clock (RTC), a 32kHz
-clock gate, high-accuracy VREF for use with an external ADC, flexible
-dual-input power path, 10 bit SAR ADC for battery temperature monitor and
-1S battery charger with scalable charge currents.
-
-Required properties:
- - compatible : Should be "rohm,bd70528"
- - reg : I2C slave address.
- - interrupts : The interrupt line the device is connected to.
- - interrupt-controller : To indicate BD70528 acts as an interrupt controller.
- - #interrupt-cells : Should be 2. Usage is compliant to the 2 cells
- variant of ../interrupt-controller/interrupts.txt
- - gpio-controller : To indicate BD70528 acts as a GPIO controller.
- - #gpio-cells : Should be 2. The first cell is the pin number and
- the second cell is used to specify flags. See
- ../gpio/gpio.txt for more information.
- - #clock-cells : Should be 0.
- - regulators: : List of child nodes that specify the regulators.
- Please see ../regulator/rohm,bd70528-regulator.txt
-
-Optional properties:
- - clock-output-names : Should contain name for output clock.
-
-Example:
-/* External oscillator */
-osc: oscillator {
- compatible = "fixed-clock";
- #clock-cells = <1>;
- clock-frequency = <32768>;
- clock-output-names = "osc";

-* NVIDIA Tegra Secure Digital Host Controller
-
-This controller on Tegra family SoCs 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 sdhci-tegra driver.
-
-Required properties:
-- compatible : should be one of:
- - "nvidia,tegra20-sdhci": for Tegra20
- - "nvidia,tegra30-sdhci": for Tegra30
- - "nvidia,tegra114-sdhci": for Tegra114
- - "nvidia,tegra124-sdhci": for Tegra124 and Tegra132
- - "nvidia,tegra210-sdhci": for Tegra210
- - "nvidia,tegra186-sdhci": for Tegra186
- - "nvidia,tegra194-sdhci": for Tegra194
-- clocks: For Tegra210, Tegra186 and Tegra194 must contain two entries.
- One for the module clock and one for the timeout clock.
- For all other Tegra devices, must contain a single entry for
- the module clock. See ../clocks/clock-bindings.txt for details.
-- clock-names: For Tegra210, Tegra186 and Tegra194 must contain the
- strings 'sdhci' and 'tmclk' to represent the module and
- the timeout clocks, respectively.
- For all other Tegra devices must contain the string 'sdhci'
- to represent the module clock.
-- resets : Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names : Must include the following entries:
- - sdhci
-
-Optional properties:
-- power-gpios : Specify GPIOs for power control
-
-Example:
-
-sdhci@c8000200 {
- compatible = "nvidia,tegra20-sdhci";
- reg = <0xc8000200 0x200>;
- interrupts = <47>;
- clocks = <&tegra_car 14>;
- resets = <&tegra_car 14>;
- reset-names = "sdhci";
- cd-gpios = <&gpio 69 0>; /* gpio PI5 */
- wp-gpios = <&gpio 57 0>; /* gpio PH1 */
- power-gpios = <&gpio 155 0>; /* gpio PT3 */
- bus-width = <8>;
-};
-
-Optional properties for Tegra210, Tegra186 and Tegra194:
-- pinctrl-names, pinctrl-0, pinctrl-1 : Specify pad voltage
- configurations. Valid pinctrl-names are "sdmmc-3v3" and "sdmmc-1v8"
- for controllers supporting multiple voltage levels. The order of names
- should correspond to the pin configuration states in pinctrl-0 and
- pinctrl-1.
-- pinctrl-names : "sdmmc-3v3-drv" and "sdmmc-1v8-drv" are applicable for
- Tegra210 where pad config registers are in the pinmux register domain
- for pull-up-strength and pull-down-strength values configuration when
- using pads at 3V3 and 1V8 levels.
-- nvidia,only-1-8-v : The presence of this property indicates that the
- controller operates at a 1.8 V fixed I/O voltage.
-- nvidia,pad-autocal-pull-up-offset-3v3,
- nvidia,pad-autocal-pull-down-offset-3v3 : Specify drive strength
- calibration offsets for 3.3 V signaling modes.
-- nvidia,pad-autocal-pull-up-offset-1v8,
- nvidia,pad-autocal-pull-down-offset-1v8 : Specify drive strength
- calibration offsets for 1.8 V signaling modes.
-- nvidia,pad-autocal-pull-up-offset-3v3-timeout,
- nvidia,pad-autocal-pull-down-offset-3v3-timeout : Specify drive
- strength used as a fallback in case the automatic calibration times
- out on a 3.3 V signaling mode.
-- nvidia,pad-autocal-pull-up-offset-1v8-timeout,
- nvidia,pad-autocal-pull-down-offset-1v8-timeout : Specify drive
- strength used as a fallback in case the automatic calibration times
- out on a 1.8 V signaling mode.
-- nvidia,pad-autocal-pull-up-offset-sdr104,
- nvidia,pad-autocal-pull-down-offset-sdr104 : Specify drive strength
- calibration offsets for SDR104 mode.
-- nvidia,pad-autocal-pull-up-offset-hs400,
- nvidia,pad-autocal-pull-down-offset-hs400 : Specify drive strength
- calibration offsets for HS400 mode.
-- nvidia,default-tap : Specify the default inbound sampling clock
- trimmer value for non-tunable modes.
-- nvidia,default-trim : Specify the default outbound clock trimmer
- value.
-- nvidia,dqs-trim : Specify DQS trim value for HS400 timing
-
- Notes on the pad calibration pull up and pulldown offset values:
- - The property values are drive codes which are programmed into the
- PD_OFFSET and PU_OFFSET sections of the
- SDHCI_TEGRA_AUTO_CAL_CONFIG register.
- - A higher value corresponds to higher drive strength. Please refer
- to the reference manual of the SoC for correct values.
- - The SDR104 and HS400 timing specific values are used in
- corresponding modes if specified.
-
- Notes on tap and trim values:
- - The values are used for compensating trace length differences
- by adjusting the sampling point.
- - The values are programmed to the Vendor Clock Control Register.
- Please refer to the reference manual of the SoC for correct
- values.
- - The DQS trim values are only used on controllers which support
- HS400 timing. Only SDMMC4 on Tegra210 and Tegra 186 supports
- HS400.

- for information on the property specifics.
-- phy-mode: see ethernet.txt file in the same directory
-- #address-cells: should be 1
-- #size-cells: should be 1
-
-Optional properties:
-- clocks: When provided, must be two phandles to the functional clocks nodes
- of the GENET block. The first phandle is the main GENET clock used during
- normal operation, while the second phandle is the Wake-on-LAN clock.
-- clock-names: When provided, names of the functional clock phandles, first
- name should be "enet" and second should be "enet-wol".
-

-Properties for an MDIO bus multiplexer found in Broadcom iProc based SoCs.
-
-This MDIO bus multiplexer defines buses that could be internal as well as
-external to SoCs and could accept MDIO transaction compatible to C-22 or
-C-45 Clause. When child bus is selected, one needs to select these two
-properties as well to generate desired MDIO transaction on appropriate bus.
-
-Required properties in addition to the generic multiplexer properties:
-
-MDIO multiplexer node:
-- compatible: brcm,mdio-mux-iproc.
-
-Every non-ethernet PHY requires a compatible so that it could be probed based
-on this compatible string.
-
-Optional properties:
-- clocks: phandle of the core clock which drives the mdio block.
-
-Additional information regarding generic multiplexer properties can be found
-at- Documentation/devicetree/bindings/net/mdio-mux.yaml
-
-
-for example:
- mdio_mux_iproc: mdio-mux@66020000 {

+description: |
+ The BAM Data Multiplexer provides access to the network data channels
+ of modems integrated into many older Qualcomm SoCs, e.g. Qualcomm MSM8916
+ or MSM8974. It is built using a simple protocol layer on top of a DMA engine
+ (Qualcomm BAM DMA) and bidirectional interrupts to coordinate power control.
+
+ Note that this schema does not directly describe a hardware block but rather
+ a firmware convention that combines several other hardware blocks (such as the
+ DMA engine). As such it is specific to a firmware version, not a particular
+ SoC or hardware version.

- PAXB-based root complex is used for external endpoint devices. PAXC-based
-root complex is connected to emulated endpoint devices internal to the ASIC
-- reg: base address and length of the PCIe controller I/O register space
-- #interrupt-cells: set to <1>
-- interrupt-map-mask and interrupt-map, standard PCI properties to define the
- mapping of the PCIe interface to interrupt numbers
-- linux,pci-domain: PCI domain ID. Should be unique for each host controller
-- bus-range: PCI bus numbers covered
-- #address-cells: set to <3>
-- #size-cells: set to <2>
-- device_type: set to "pci"
-- ranges: ranges for the PCI memory and I/O regions
-
-Optional properties:
-- phys: phandle of the PCIe PHY device
-- phy-names: must be "pcie-phy"
-- dma-coherent: present if DMA operations are coherent
-- dma-ranges: Some PAXB-based root complexes do not have inbound mapping done
- by the ASIC after power on reset. In this case, SW is required to configure
-the mapping, based on inbound memory regions specified by this property.
-
-- brcm,pcie-ob: Some iProc SoCs do not have the outbound address mapping done
-by the ASIC after power on reset. In this case, SW needs to configure it
-
-If the brcm,pcie-ob property is present, the following properties become
-effective:
-
-Required:
-- brcm,pcie-ob-axi-offset: The offset from the AXI address to the internal
-address used by the iProc PCIe core (not the PCIe address)
-
-MSI support (optional):
-
-For older platforms without MSI integrated in the GIC, iProc PCIe core provides
-an event queue based MSI support. The iProc MSI uses host memories to store
-MSI posted writes in the event queues
-
-On newer iProc platforms, gicv2m or gicv3-its based MSI support should be used
-
-- msi-map: Maps a Requester ID to an MSI controller and associated MSI
-sideband data
-
-- msi-parent: Link to the device node of the MSI controller, used when no MSI
-sideband data is passed between the iProc PCIe controller and the MSI
-controller
-
-Refer to the following binding documents for more detailed description on
-the use of 'msi-map' and 'msi-parent':
- Documentation/devicetree/bindings/pci/pci-msi.txt
- Documentation/devicetree/bindings/interrupt-controller/msi.txt
-
-When the iProc event queue based MSI is used, one needs to define the
-following properties in the MSI device node:
-- compatible: Must be "brcm,iproc-msi"
-- msi-controller: claims itself as an MSI controller
-- interrupts: List of interrupt IDs from its parent interrupt device
-

+description: |
+ The Tag-and-Data units (TADs) maintain coherence and contain CN10K
+ shared on-chip last level cache (LLC). The tad pmu measures the
+ performance of last-level cache. Each tad pmu supports up to eight
+ counters.
+
+ The DT setup comprises of number of tad blocks, the sizes of pmu
+ regions, tad blocks and overall base address of the HW.

-
-pinctrl-use-default: Boolean. Indicates that the OS can use the boot default

-
-The pin configuration nodes need not be direct children of the pin controller
-device; they may be grandchildren, for example. Whether this is legal, and
-whether there is any interaction between the child and intermediate parent
-nodes, is again defined entirely by the binding for the individual pin

+description: |
+ Pin controller devices should contain the pin configuration nodes that client
+ devices reference.
+
+ The contents of each of those pin configuration child nodes is defined
+ entirely by the binding for the individual pin controller device. There
+ exists no common standard for this content. The pinctrl framework only
+ provides generic helper bindings that the pin controller driver can use.
+
+ The pin configuration nodes need not be direct children of the pin controller
+ device; they may be grandchildren, for example. Whether this is legal, and
+ whether there is any interaction between the child and intermediate parent
+ nodes, is again defined entirely by the binding for the individual pin
+ controller device.

+
+description: |
+ Bindings for the JH7100 RISC-V SoC from StarFive Ltd.
+
+ Out of the SoC's many pins only the ones named PAD_GPIO[0] to PAD_GPIO[63]
+ and PAD_FUNC_SHARE[0] to PAD_FUNC_SHARE[141] can be multiplexed and have
+ configurable bias, drive strength, schmitt trigger etc. The SoC has an
+ interesting 2-layered approach to pin muxing best illustrated by the diagram
+ below.
+
+ Signal group 0, 1, ... or 6
+ ___|___
+ | |
+ LCD output -----------------| |
+ CMOS Camera interface ------| |--- PAD_GPIO[0]
+ Ethernet PHY interface -----| MUX |--- PAD_GPIO[1]

+ | | -----|---|-- GPIO63 ---| |
+ | | | | | | -------
+ UART0 UART1 --
+
+
+ The big MUX in the diagram only has 7 different ways of mapping peripherals
+ on the left to pins on the right. StarFive calls the 7 configurations "signal
+ groups".
+ However some peripherals have their I/O go through the 64 "GPIOs". The
+ diagram only shows UART0 and UART1, but this also includes a number of other
+ UARTs, I2Cs, SPIs, PWMs etc. All these peripherals are connected to all 64
+ GPIOs such that any GPIO can be set up to be controlled by any of the
+ peripherals.
+ Note that signal group 0 doesn't map any of the GPIOs to pins, and only
+ signal group 1 maps the GPIOs to the pins named PAD_GPIO[0] to PAD_GPIO[63].

+ represents a generic power domain provider, as documented in

-Binding for Maxim MAX77686 regulators
-
-This is a part of the device tree bindings of MAX77686 multi-function device.
-More information can be found in ../mfd/max77686.txt file.
-
-The MAX77686 PMIC has 9 high-efficiency Buck and 26 Low-DropOut (LDO)
-regulators that can be controlled over I2C.
-
-Following properties should be present in main device node of the MFD chip.
-
-Optional node:
-- voltage-regulators : The regulators of max77686 have to be instantiated
- under subnode named "voltage-regulators" using the following format.
-
- regulator_name {
- regulator-compatible = LDOn/BUCKn
- standard regulator constraints....
- };
- refer Documentation/devicetree/bindings/regulator/regulator.txt
-
- The regulator node's name should be initialized with a string
-to get matched with their hardware counterparts as follow:
-
- -LDOn : for LDOs, where n can lie in range 1 to 26.
- example: LDO1, LDO2, LDO26.
- -BUCKn : for BUCKs, where n can lie in range 1 to 9.
- example: BUCK1, BUCK5, BUCK9.
-
- Regulators which can be turned off during system suspend:
- -LDOn : 2, 6-8, 10-12, 14-16,
- -BUCKn : 1-4.
- Use standard regulator bindings for it ('regulator-off-in-suspend').
-
- LDO20, LDO21, LDO22, BUCK8 and BUCK9 can be configured to GPIO enable
- control. To turn this feature on this property must be added to the regulator
- sub-node:
- - maxim,ena-gpios : one GPIO specifier enable control (the gpio
- flags are actually ignored and always
- ACTIVE_HIGH is used)
-
-Example:
-
- max77686: pmic@9 {
- compatible = "maxim,max77686";
- interrupt-parent = <&wakeup_eint>;
- interrupts = <26 IRQ_TYPE_LEVEL_LOW>;
- reg = <0x09>;

-Command DB
----------
-
-Command DB is a database that provides a mapping between resource key and the
-resource address for a system resource managed by a remote processor. The data
-is stored in a shared memory region and is loaded by the remote processor.
-
-Some of the Qualcomm Technologies Inc SoC's have hardware accelerators for
-controlling shared resources. Depending on the board configuration the shared
-resource properties may change. These properties are dynamically probed by the
-remote processor and made available in the shared memory.
-
-The bindings for Command DB is specified in the reserved-memory section in
-devicetree. The devicetree representation of the command DB driver should be:
-
-Properties:
-- compatible:
- Usage: required
- Value type: <string>
- Definition: Should be "qcom,cmd-db"
-
-- reg:
- Usage: required
- Value type: <prop encoded array>
- Definition: The register address that points to the actual location of
- the Command DB in memory.
-
-Example:
-
- reserved-memory {
- [...]
- reserved-memory@85fe0000 {
- reg = <0x0 0x85fe0000 0x0 0x20000>;

+description: |
+ In Tegra186, the BPMP (Boot and Power Management Processor) implements
+ an interface that is used to read system temperatures, including CPU
+ cluster and GPU temperatures. This binding describes the thermal
+ sensor that is exposed by BPMP.
+
+ The BPMP thermal node must be located directly inside the main BPMP
+ node. See ../firmware/nvidia,tegra186-bpmp.yaml for details of the
+ BPMP binding.
+
+ This node represents a thermal sensor. See
+
+ Documentation/devicetree/bindings/thermal/thermal-sensor.yaml
+
+ for details of the core thermal binding.

Auxiliary Bus
=============
-In some subsystems, the functionality of the core device (PCI/ACPI/other) is
-too complex for a single device to be managed by a monolithic driver
-(e.g. Sound Open Firmware), multiple devices might implement a common
-intersection of functionality (e.g. NICs + RDMA), or a driver may want to
-export an interface for another subsystem to drive (e.g. SIOV Physical Function
-export Virtual Function management). A split of the functionality into child-
-devices representing sub-domains of functionality makes it possible to
-compartmentalize, layer, and distribute domain-specific concerns via a Linux
-device-driver model.
-
-An example for this kind of requirement is the audio subsystem where a single
-IP is handling multiple entities such as HDMI, Soundwire, local devices such as
-mics/speakers etc. The split for the core's functionality can be arbitrary or
-be defined by the DSP firmware topology and include hooks for test/debug. This
-allows for the audio core device to be minimal and focused on hardware-specific
-control and communication.
-
-Each auxiliary_device represents a part of its parent functionality. The
-generic behavior can be extended and specialized as needed by encapsulating an
-auxiliary_device within other domain-specific structures and the use of .ops
-callbacks. Devices on the auxiliary bus do not share any structures and the use
-of a communication channel with the parent is domain-specific.
-
-Note that ops are intended as a way to augment instance behavior within a class
-of auxiliary devices, it is not the mechanism for exporting common
-infrastructure from the parent. Consider EXPORT_SYMBOL_NS() to convey
-infrastructure from the parent module to the auxiliary module(s).
-
+.. kernel-doc:: drivers/base/auxiliary.c
+ :doc: PURPOSE
When Should the Auxiliary Bus Be Used
=====================================
-The auxiliary bus is to be used when a driver and one or more kernel modules,
-who share a common header file with the driver, need a mechanism to connect and
-provide access to a shared object allocated by the auxiliary_device's
-registering driver. The registering driver for the auxiliary_device(s) and the
-kernel module(s) registering auxiliary_drivers can be from the same subsystem,
-or from multiple subsystems.
-
-The emphasis here is on a common generic interface that keeps subsystem
-customization out of the bus infrastructure.
-
-One example is a PCI network device that is RDMA-capable and exports a child
-device to be driven by an auxiliary_driver in the RDMA subsystem. The PCI
-driver allocates and registers an auxiliary_device for each physical
-function on the NIC. The RDMA driver registers an auxiliary_driver that claims
-each of these auxiliary_devices. This conveys data/ops published by the parent
-PCI device/driver to the RDMA auxiliary_driver.
-
-Another use case is for the PCI device to be split out into multiple sub
-functions. For each sub function an auxiliary_device is created. A PCI sub
-function driver binds to such devices that creates its own one or more class
-devices. A PCI sub function auxiliary device is likely to be contained in a
-struct with additional attributes such as user defined sub function number and
-optional attributes such as resources and a link to the parent device. These
-attributes could be used by systemd/udev; and hence should be initialized
-before a driver binds to an auxiliary_device.
-
-A key requirement for utilizing the auxiliary bus is that there is no
-dependency on a physical bus, device, register accesses or regmap support.
-These individual devices split from the core cannot live on the platform bus as
-they are not physical devices that are controlled by DT/ACPI. The same
-argument applies for not using MFD in this scenario as MFD relies on individual
-function devices being physical devices.
-
-Auxiliary Device
-================
-
-An auxiliary_device represents a part of its parent device's functionality. It
-is given a name that, combined with the registering drivers KBUILD_MODNAME,
-creates a match_name that is used for driver binding, and an id that combined
-with the match_name provide a unique name to register with the bus subsystem.
-
-Registering an auxiliary_device is a two-step process. First call
-auxiliary_device_init(), which checks several aspects of the auxiliary_device
-struct and performs a device_initialize(). After this step completes, any
-error state must have a call to auxiliary_device_uninit() in its resolution path.
-The second step in registering an auxiliary_device is to perform a call to
-auxiliary_device_add(), which sets the name of the device and add the device to
-the bus.
-
-Unregistering an auxiliary_device is also a two-step process to mirror the
-register process. First call auxiliary_device_delete(), then call
-auxiliary_device_uninit().
-
-.. code-block:: c
-
- struct auxiliary_device {
- struct device dev;
- const char *name;
- u32 id;
- };
-
-If two auxiliary_devices both with a match_name "mod.foo" are registered onto
-the bus, they must have unique id values (e.g. "x" and "y") so that the
-registered devices names are "mod.foo.x" and "mod.foo.y". If match_name + id
-are not unique, then the device_add fails and generates an error message.
-
-The auxiliary_device.dev.type.release or auxiliary_device.dev.release must be
-populated with a non-NULL pointer to successfully register the auxiliary_device.
-
-The auxiliary_device.dev.parent must also be populated.

Auxiliary Device Memory Model and Lifespan
------------------------------------------
-The registering driver is the entity that allocates memory for the
-auxiliary_device and register it on the auxiliary bus. It is important to note
-that, as opposed to the platform bus, the registering driver is wholly
-responsible for the management for the memory used for the driver object.
-
-A parent object, defined in the shared header file, contains the
-auxiliary_device. It also contains a pointer to the shared object(s), which
-also is defined in the shared header. Both the parent object and the shared
-object(s) are allocated by the registering driver. This layout allows the
-auxiliary_driver's registering module to perform a container_of() call to go
-from the pointer to the auxiliary_device, that is passed during the call to the
-auxiliary_driver's probe function, up to the parent object, and then have
-access to the shared object(s).
-
-The memory for the auxiliary_device is freed only in its release() callback
-flow as defined by its registering driver.
-
-The memory for the shared object(s) must have a lifespan equal to, or greater
-than, the lifespan of the memory for the auxiliary_device. The auxiliary_driver
-should only consider that this shared object is valid as long as the
-auxiliary_device is still registered on the auxiliary bus. It is up to the
-registering driver to manage (e.g. free or keep available) the memory for the
-shared object beyond the life of the auxiliary_device.
-
-The registering driver must unregister all auxiliary devices before its own
-driver.remove() is completed.
+.. kernel-doc:: include/linux/auxiliary_bus.h
+ :doc: DEVICE_LIFESPAN
+
Auxiliary Drivers
=================
-Auxiliary drivers follow the standard driver model convention, where
-discovery/enumeration is handled by the core, and drivers
-provide probe() and remove() methods. They support power management
-and shutdown notifications using the standard conventions.
-

- int (*suspend)(struct auxiliary_device *, pm_message_t);
- int (*resume)(struct auxiliary_device *);
- struct device_driver driver;
- const struct auxiliary_device_id *id_table;
- };
-
-Auxiliary drivers register themselves with the bus by calling
-auxiliary_driver_register(). The id_table contains the match_names of auxiliary
-devices that a driver can bind with.
+.. kernel-doc:: drivers/base/auxiliary.c
+ :identifiers: __auxiliary_driver_register auxiliary_driver_unregister
Example Usage
=============
-Auxiliary devices are created and registered by a subsystem-level core device
-that needs to break up its functionality into smaller fragments. One way to
-extend the scope of an auxiliary_device is to encapsulate it within a domain-
-pecific structure defined by the parent device. This structure contains the
-auxiliary_device and any associated shared data/callbacks needed to establish
-the connection with the parent.
-
-An example is:
-
-.. code-block:: c
-
- struct foo {
- struct auxiliary_device auxdev;
- void (*connect)(struct auxiliary_device *auxdev);
- void (*disconnect)(struct auxiliary_device *auxdev);
- void *data;
- };
-
-The parent device then registers the auxiliary_device by calling
-auxiliary_device_init(), and then auxiliary_device_add(), with the pointer to
-the auxdev member of the above structure. The parent provides a name for the
-auxiliary_device that, combined with the parent's KBUILD_MODNAME, creates a
-match_name that is be used for matching and binding with a driver.
-
-Whenever an auxiliary_driver is registered, based on the match_name, the
-auxiliary_driver's probe() is invoked for the matching devices. The
-auxiliary_driver can also be encapsulated inside custom drivers that make the
-core device's functionality extensible by adding additional domain-specific ops
-as follows:
-
-.. code-block:: c
-
- struct my_ops {
- void (*send)(struct auxiliary_device *auxdev);
- void (*receive)(struct auxiliary_device *auxdev);
- };
-
-
- struct my_driver {
- struct auxiliary_driver auxiliary_drv;
- const struct my_ops ops;
- };
-
-An example of this type of usage is:
-
-.. code-block:: c
-
- const struct auxiliary_device_id my_auxiliary_id_table[] = {
- { .name = "foo_mod.foo_dev" },
- { },
- };
-
- const struct my_ops my_custom_ops = {
- .send = my_tx,
- .receive = my_rx,
- };
-
- const struct my_driver my_drv = {
- .auxiliary_drv = {
- .name = "myauxiliarydrv",
- .id_table = my_auxiliary_id_table,
- .probe = my_probe,
- .remove = my_remove,
- .shutdown = my_shutdown,
- },
- .ops = my_custom_ops,
- };

-
-
-Line Discipline
----------------
-
-Line disciplines are registered with tty_register_ldisc() passing the
-discipline number and the ldisc structure. At the point of registration the
-discipline must be ready to use and it is possible it will get used before
-the call returns success. If the call returns an error then it won't get
-called. Do not re-use ldisc numbers as they are part of the userspace ABI
-and writing over an existing ldisc will cause demons to eat your computer.
-After the return the ldisc data has been copied so you may free your own
-copy of the structure. You must not re-register over the top of the line
-discipline even with the same data or your computer again will be eaten by
-demons.
-
-In order to remove a line discipline call tty_unregister_ldisc().
-In ancient times this always worked. In modern times the function will
-return -EBUSY if the ldisc is currently in use. Since the ldisc referencing
-code manages the module counts this should not usually be a concern.
-
-Heed this warning: the reference count field of the registered copies of the
-tty_ldisc structure in the ldisc table counts the number of lines using this
-discipline. The reference count of the tty_ldisc structure within a tty
-counts the number of active users of the ldisc at this instant. In effect it
-counts the number of threads of execution within an ldisc method (plus those
-about to enter and exit although this detail matters not).

-TTY side interfaces
-^^^^^^^^^^^^^^^^^^^
-
-======================= =======================================================
-open() Called when the line discipline is attached to
- the terminal. No other call into the line
- discipline for this tty will occur until it
- completes successfully. Should initialize any
- state needed by the ldisc, and set receive_room
- in the tty_struct to the maximum amount of data
- the line discipline is willing to accept from the
- driver with a single call to receive_buf().
- Returning an error will prevent the ldisc from
- being attached. Can sleep.
-
-close() This is called on a terminal when the line
- discipline is being unplugged. At the point of
- execution no further users will enter the
- ldisc code for this tty. Can sleep.
-
-hangup() Called when the tty line is hung up.
- The line discipline should cease I/O to the tty.
- No further calls into the ldisc code will occur.
- Can sleep.
-
-read() (optional) A process requests reading data from
- the line. Multiple read calls may occur in parallel
- and the ldisc must deal with serialization issues.
- If not defined, the process will receive an EIO
- error. May sleep.
-
-write() (optional) A process requests writing data to the
- line. Multiple write calls are serialized by the
- tty layer for the ldisc. If not defined, the
- process will receive an EIO error. May sleep.
-
-flush_buffer() (optional) May be called at any point between
- open and close, and instructs the line discipline
- to empty its input buffer.
-
-set_termios() (optional) Called on termios structure changes.
- The caller passes the old termios data and the
- current data is in the tty. Called under the
- termios semaphore so allowed to sleep. Serialized
- against itself only.
-
-poll() (optional) Check the status for the poll/select
- calls. Multiple poll calls may occur in parallel.
- May sleep.
-
-ioctl() (optional) Called when an ioctl is handed to the
- tty layer that might be for the ldisc. Multiple
- ioctl calls may occur in parallel. May sleep.
-
-compat_ioctl() (optional) Called when a 32 bit ioctl is handed
- to the tty layer that might be for the ldisc.
- Multiple ioctl calls may occur in parallel.
- May sleep.
-======================= =======================================================
-
-Driver Side Interfaces
-^^^^^^^^^^^^^^^^^^^^^^
-
-======================= =======================================================
-receive_buf() (optional) Called by the low-level driver to hand
- a buffer of received bytes to the ldisc for
- processing. The number of bytes is guaranteed not
- to exceed the current value of tty->receive_room.
- All bytes must be processed.
-
-receive_buf2() (optional) Called by the low-level driver to hand
- a buffer of received bytes to the ldisc for
- processing. Returns the number of bytes processed.
-
- If both receive_buf() and receive_buf2() are
- defined, receive_buf2() should be preferred.
-
-write_wakeup() May be called at any point between open and close.
- The TTY_DO_WRITE_WAKEUP flag indicates if a call
- is needed but always races versus calls. Thus the
- ldisc must be careful about setting order and to
- handle unexpected calls. Must not sleep.
-
- The driver is forbidden from calling this directly
- from the ->write call from the ldisc as the ldisc
- is permitted to call the driver write method from
- this function. In such a situation defer it.
-
-dcd_change() Report to the tty line the current DCD pin status
- changes and the relative timestamp. The timestamp
- cannot be NULL.
-======================= =======================================================
-
-
-Driver Access
-^^^^^^^^^^^^^
-
-Line discipline methods can call the following methods of the underlying
-hardware driver through the function pointers within the tty->driver
-structure:
-
-======================= =======================================================
-write() Write a block of characters to the tty device.
- Returns the number of characters accepted. The
- character buffer passed to this method is already
- in kernel space.
-
-put_char() Queues a character for writing to the tty device.
- If there is no room in the queue, the character is
- ignored.
-
-flush_chars() (Optional) If defined, must be called after
- queueing characters with put_char() in order to
- start transmission.
-
-write_room() Returns the numbers of characters the tty driver
- will accept for queueing to be written.
-
-ioctl() Invoke device specific ioctl.
- Expects data pointers to refer to userspace.
- Returns ENOIOCTLCMD for unrecognized ioctl numbers.
-
-set_termios() Notify the tty driver that the device's termios
- settings have changed. New settings are in
- tty->termios. Previous settings should be passed in
- the "old" argument.
-
- The API is defined such that the driver should return
- the actual modes selected. This means that the
- driver function is responsible for modifying any
- bits in the request it cannot fulfill to indicate
- the actual modes being used. A device with no
- hardware capability for change (e.g. a USB dongle or
- virtual port) can provide NULL for this method.
-
-throttle() Notify the tty driver that input buffers for the
- line discipline are close to full, and it should
- somehow signal that no more characters should be
- sent to the tty.
-
-unthrottle() Notify the tty driver that characters can now be
- sent to the tty without fear of overrunning the
- input buffers of the line disciplines.
-
-stop() Ask the tty driver to stop outputting characters
- to the tty device.
-
-start() Ask the tty driver to resume sending characters
- to the tty device.
-
-hangup() Ask the tty driver to hang up the tty device.
-
-break_ctl() (Optional) Ask the tty driver to turn on or off
- BREAK status on the RS-232 port. If state is -1,
- then the BREAK status should be turned on; if
- state is 0, then BREAK should be turned off.
- If this routine is not implemented, use ioctls
- TIOCSBRK / TIOCCBRK instead.
-
-wait_until_sent() Waits until the device has written out all of the
- characters in its transmitter FIFO.
-
-send_xchar() Send a high-priority XON/XOFF character to the device.
-======================= =======================================================
-
-
-Flags
-^^^^^
-
-Line discipline methods have access to tty->flags field containing the
-following interesting flags:
-
-======================= =======================================================
-TTY_THROTTLED Driver input is throttled. The ldisc should call
- tty->driver->unthrottle() in order to resume
- reception when it is ready to process more data.
-
-TTY_DO_WRITE_WAKEUP If set, causes the driver to call the ldisc's
- write_wakeup() method in order to resume
- transmission when it can accept more data
- to transmit.
-
-TTY_IO_ERROR If set, causes all subsequent userspace read/write
- calls on the tty to fail, returning -EIO.
-
-TTY_OTHER_CLOSED Device is a pty and the other side has closed.
-
-TTY_NO_WRITE_SPLIT Prevent driver from splitting up writes into
- smaller chunks.
-======================= =======================================================
-
-
-Locking
-^^^^^^^
-
-Callers to the line discipline functions from the tty layer are required to
-take line discipline locks. The same is true of calls from the driver side
-but not yet enforced.
-
-Three calls are now provided::
-
- ldisc = tty_ldisc_ref(tty);
-
-takes a handle to the line discipline in the tty and returns it. If no ldisc
-is currently attached or the ldisc is being closed and re-opened at this
-point then NULL is returned. While this handle is held the ldisc will not
-change or go away::
-
- tty_ldisc_deref(ldisc)
-
-Returns the ldisc reference and allows the ldisc to be closed. Returning the
-reference takes away your right to call the ldisc functions until you take
-a new reference::
-
- ldisc = tty_ldisc_ref_wait(tty);
-
-Performs the same function as tty_ldisc_ref except that it will wait for an
-ldisc change to complete and then return a reference to the new ldisc.
-
-While these functions are slightly slower than the old code they should have
-minimal impact as most receive logic uses the flip buffers and they only
-need to take a reference when they push bits up through the driver.
-
-A caution: The ldisc->open(), ldisc->close() and driver->set_ldisc
-functions are called with the ldisc unavailable. Thus tty_ldisc_ref will
-fail in this situation if used within these functions. Ldisc and driver
-code calling its own functions must be careful in this case.
-
-
-Driver Interface
-----------------
-
-======================= =======================================================
-open() Called when a device is opened. May sleep
-
-close() Called when a device is closed. At the point of
- return from this call the driver must make no
- further ldisc calls of any kind. May sleep
-
-write() Called to write bytes to the device. May not
- sleep. May occur in parallel in special cases.
- Because this includes panic paths drivers generally
- shouldn't try and do clever locking here.
-
-put_char() Stuff a single character onto the queue. The
- driver is guaranteed following up calls to
- flush_chars.
-
-flush_chars() Ask the kernel to write put_char queue
-
-write_room() Return the number of characters that can be stuffed
- into the port buffers without overflow (or less).
- The ldisc is responsible for being intelligent
- about multi-threading of write_room/write calls
-
-ioctl() Called when an ioctl may be for the driver
-
-set_termios() Called on termios change, serialized against
- itself by a semaphore. May sleep.
-
-set_ldisc() Notifier for discipline change. At the point this
- is done the discipline is not yet usable. Can now
- sleep (I think)
-
-throttle() Called by the ldisc to ask the driver to do flow
- control. Serialization including with unthrottle
- is the job of the ldisc layer.
-
-unthrottle() Called by the ldisc to ask the driver to stop flow
- control.
-
-stop() Ldisc notifier to the driver to stop output. As with
- throttle the serializations with start() are down
- to the ldisc layer.
-
-start() Ldisc notifier to the driver to start output.
-
-hangup() Ask the tty driver to cause a hangup initiated
- from the host side. [Can sleep ??]
-
-break_ctl() Send RS232 break. Can sleep. Can get called in
- parallel, driver must serialize (for now), and
- with write calls.
-
-wait_until_sent() Wait for characters to exit the hardware queue
- of the driver. Can sleep
-
-send_xchar() Send XON/XOFF and if possible jump the queue with
- it in order to get fast flow control responses.
- Cannot sleep ??

-FS-Cache Cache backend API
-==========================
+=================
+Cache Backend API
+=================
The FS-Cache system provides an API by which actual caches can be supplied to
FS-Cache for it to then serve out to network filesystems and other interested
-parties.
+parties. This API is used by::
-This API is declared in <linux/fscache-cache.h>.
+ #include <linux/fscache-cache.h>.
-Initialising and Registering a Cache
-====================================
-
-To start off, a cache definition must be initialised and registered for each
-cache the backend wants to make available. For instance, CacheFS does this in
-the fill_super() operation on mounting.
-
-The cache definition (struct fscache_cache) should be initialised by calling::
-
- void fscache_init_cache(struct fscache_cache *cache,
- struct fscache_cache_ops *ops,
- const char *idfmt,
- ...);
-
-Where:
-
- * "cache" is a pointer to the cache definition;
-
- * "ops" is a pointer to the table of operations that the backend supports on
- this cache; and
-
- * "idfmt" is a format and printf-style arguments for constructing a label
- for the cache.
-
-
-The cache should then be registered with FS-Cache by passing a pointer to the
-previously initialised cache definition to::
-
- int fscache_add_cache(struct fscache_cache *cache,
- struct fscache_object *fsdef,
- const char *tagname);
-
-Two extra arguments should also be supplied:
-
- * "fsdef" which should point to the object representation for the FS-Cache
- master index in this cache. Netfs primary index entries will be created
- here. FS-Cache keeps the caller's reference to the index object if
- successful and will release it upon withdrawal of the cache.
-
- * "tagname" which, if given, should be a text string naming this cache. If
- this is NULL, the identifier will be used instead. For CacheFS, the
- identifier is set to name the underlying block device and the tag can be
- supplied by mount.
-
-This function may return -ENOMEM if it ran out of memory or -EEXIST if the tag
-is already in use. 0 will be returned on success.
-
-
-Unregistering a Cache
-=====================
-
-A cache can be withdrawn from the system by calling this function with a
-pointer to the cache definition::
-
- void fscache_withdraw_cache(struct fscache_cache *cache);
-
-In CacheFS's case, this is called by put_super().
-
-
-Security
+Overview
========
-The cache methods are executed one of two contexts:
-
- (1) that of the userspace process that issued the netfs operation that caused
- the cache method to be invoked, or
-
- (2) that of one of the processes in the FS-Cache thread pool.
-
-In either case, this may not be an appropriate context in which to access the
-cache.
-
-The calling process's fsuid, fsgid and SELinux security identities may need to
-be masqueraded for the duration of the cache driver's access to the cache.
-This is left to the cache to handle; FS-Cache makes no effort in this regard.
-
+Interaction with the API is handled on three levels: cache, volume and data
+storage, and each level has its own type of cookie object:
-Control and Statistics Presentation
-===================================
+ ======================= =======================
+ COOKIE C TYPE
+ ======================= =======================
+ Cache cookie struct fscache_cache
+ Volume cookie struct fscache_volume
+ Data storage cookie struct fscache_cookie
+ ======================= =======================
-The cache may present data to the outside world through FS-Cache's interfaces
-in sysfs and procfs - the former for control and the latter for statistics.
+Cookies are used to provide some filesystem data to the cache, manage state and
+pin the cache during access in addition to acting as reference points for the
+API functions. Each cookie has a debugging ID that is included in trace points
+to make it easier to correlate traces. Note, though, that debugging IDs are
+simply allocated from incrementing counters and will eventually wrap.
-A sysfs directory called /sys/fs/fscache/<cachetag>/ is created if CONFIG_SYSFS
-is enabled. This is accessible through the kobject struct fscache_cache::kobj
-and is for use by the cache as it sees fit.
+The cache backend and the network filesystem can both ask for cache cookies -
+and if they ask for one of the same name, they'll get the same cookie. Volume
+and data cookies, however, are created at the behest of the filesystem only.
-Relevant Data Structures
-========================
+Cache Cookies
+=============
- * Index/Data file FS-Cache representation cookie::
+Caches are represented in the API by cache cookies. These are objects of
+type::
- struct fscache_cookie {
- struct fscache_object_def *def;
- struct fscache_netfs *netfs;
- void *netfs_data;
- ...
- };
-
- The fields that might be of use to the backend describe the object
- definition, the netfs definition and the netfs's data for this cookie.
- The object definition contain functions supplied by the netfs for loading
- and matching index entries; these are required to provide some of the
- cache operations.
-
-
- * In-cache object representation::
-
- struct fscache_object {
- int debug_id;
- enum {
- FSCACHE_OBJECT_RECYCLING,
- ...
- } state;
- spinlock_t lock
- struct fscache_cache *cache;
- struct fscache_cookie *cookie;
+ struct fscache_cache {
+ void *cache_priv;
+ unsigned int debug_id;
+ char *name;
...
};
- Structures of this type should be allocated by the cache backend and
- passed to FS-Cache when requested by the appropriate cache operation. In
- the case of CacheFS, they're embedded in CacheFS's internal object
- structures.
+There are a few fields that the cache backend might be interested in. The
+``debug_id`` can be used in tracing to match lines referring to the same cache
+and ``name`` is the name the cache was registered with. The ``cache_priv``
+member is private data provided by the cache when it is brought online. The
+other fields are for internal use.
- The debug_id is a simple integer that can be used in debugging messages
- that refer to a particular object. In such a case it should be printed
- using "OBJ%x" to be consistent with FS-Cache.
- Each object contains a pointer to the cookie that represents the object it
- is backing. An object should retired when put_object() is called if it is
- in state FSCACHE_OBJECT_RECYCLING. The fscache_object struct should be
- initialised by calling fscache_object_init(object).
+Registering a Cache
+===================
+When a cache backend wants to bring a cache online, it should first register
+the cache name and that will get it a cache cookie. This is done with::
- * FS-Cache operation record::
+ struct fscache_cache *fscache_acquire_cache(const char *name);
- struct fscache_operation {
- atomic_t usage;
- struct fscache_object *object;
- unsigned long flags;
- #define FSCACHE_OP_EXCLUSIVE
- void (*processor)(struct fscache_operation *op);
- void (*release)(struct fscache_operation *op);
- ...
- };
+This will look up and potentially create a cache cookie. The cache cookie may
+have already been created by a network filesystem looking for it, in which case
+that cache cookie will be used. If the cache cookie is not in use by another
+cache, it will be moved into the preparing state, otherwise it will return
+busy.
- FS-Cache has a pool of threads that it uses to give CPU time to the
- various asynchronous operations that need to be done as part of driving
- the cache. These are represented by the above structure. The processor
- method is called to give the op CPU time, and the release method to get
- rid of it when its usage count reaches 0.
+If successful, the cache backend can then start setting up the cache. In the
+event that the initialisation fails, the cache backend should call::
- An operation can be made exclusive upon an object by setting the
- appropriate flag before enqueuing it with fscache_enqueue_operation(). If
- an operation needs more processing time, it should be enqueued again.
+ void fscache_relinquish_cookie(struct fscache_cache *cache);
+to reset and discard the cookie.
- * FS-Cache retrieval operation record::
- struct fscache_retrieval {
- struct fscache_operation op;
- struct address_space *mapping;
- struct list_head *to_do;
- ...
- };
+Bringing a Cache Online
+=======================
- A structure of this type is allocated by FS-Cache to record retrieval and
- allocation requests made by the netfs. This struct is then passed to the
- backend to do the operation. The backend may get extra refs to it by
- calling fscache_get_retrieval() and refs may be discarded by calling
- fscache_put_retrieval().
+Once the cache is set up, it can be brought online by calling::
- A retrieval operation can be used by the backend to do retrieval work. To
- do this, the retrieval->op.processor method pointer should be set
- appropriately by the backend and fscache_enqueue_retrieval() called to
- submit it to the thread pool. CacheFiles, for example, uses this to queue
- page examination when it detects PG_lock being cleared.
+ int fscache_add_cache(struct fscache_cache *cache,
+ const struct fscache_cache_ops *ops,
+ void *cache_priv);
- The to_do field is an empty list available for the cache backend to use as
- it sees fit.
+This stores the cache operations table pointer and cache private data into the
+cache cookie and moves the cache to the active state, thereby allowing accesses
+to take place.
- * FS-Cache storage operation record::
+Withdrawing a Cache From Service
+================================
- struct fscache_storage {
- struct fscache_operation op;
- pgoff_t store_limit;
- ...
- };
+The cache backend can withdraw a cache from service by calling this function::
- A structure of this type is allocated by FS-Cache to record outstanding
- writes to be made. FS-Cache itself enqueues this operation and invokes
- the write_page() method on the object at appropriate times to effect
- storage.
+ void fscache_withdraw_cache(struct fscache_cache *cache);
+This moves the cache to the withdrawn state to prevent new cache- and
+volume-level accesses from starting and then waits for outstanding cache-level
+accesses to complete.
-Cache Operations
-================
+The cache must then go through the data storage objects it has and tell fscache
+to withdraw them, calling::
-The cache backend provides FS-Cache with a table of operations that can be
-performed on the denizens of the cache. These are held in a structure of type:
+ void fscache_withdraw_cookie(struct fscache_cookie *cookie);
- ::
+on the cookie that each object belongs to. This schedules the specified cookie
+for withdrawal. This gets offloaded to a workqueue. The cache backend can
+test for completion by calling::
- struct fscache_cache_ops
+ bool fscache_are_objects_withdrawn(struct fscache_cookie *cache);
- * Name of cache provider [mandatory]::
+Once all the cookies are withdrawn, a cache backend can withdraw all the
+volumes, calling::
- const char *name
+ void fscache_withdraw_volume(struct fscache_volume *volume);
- This isn't strictly an operation, but should be pointed at a string naming
- the backend.
+to tell fscache that a volume has been withdrawn. This waits for all
+outstanding accesses on the volume to complete before returning.
+When the the cache is completely withdrawn, fscache should be notified by
+calling::
- * Allocate a new object [mandatory]::
+ void fscache_cache_relinquish(struct fscache_cache *cache);
- struct fscache_object *(*alloc_object)(struct fscache_cache *cache,
- struct fscache_cookie *cookie)
+to clear fields in the cookie and discard the caller's ref on it.
- This method is used to allocate a cache object representation to back a
- cookie in a particular cache. fscache_object_init() should be called on
- the object to initialise it prior to returning.
- This function may also be used to parse the index key to be used for
- multiple lookup calls to turn it into a more convenient form. FS-Cache
- will call the lookup_complete() method to allow the cache to release the
- form once lookup is complete or aborted.
+Volume Cookies
+==============
+Within a cache, the data storage objects are organised into logical volumes.
+These are represented in the API as objects of type::
- * Look up and create object [mandatory]::
+ struct fscache_volume {
+ struct fscache_cache *cache;
+ void *cache_priv;
+ unsigned int debug_id;
+ char *key;
+ unsigned int key_hash;
+ ...
+ u8 coherency_len;
+ u8 coherency[];
+ };
- void (*lookup_object)(struct fscache_object *object)
+There are a number of fields here that are of interest to the caching backend:
- This method is used to look up an object, given that the object is already
- allocated and attached to the cookie. This should instantiate that object
- in the cache if it can.
+ * ``cache`` - The parent cache cookie.
- The method should call fscache_object_lookup_negative() as soon as
- possible if it determines the object doesn't exist in the cache. If the
- object is found to exist and the netfs indicates that it is valid then
- fscache_obtained_object() should be called once the object is in a
- position to have data stored in it. Similarly, fscache_obtained_object()
- should also be called once a non-present object has been created.
+ * ``cache_priv`` - A place for the cache to stash private data.
- If a lookup error occurs, fscache_object_lookup_error() should be called
- to abort the lookup of that object.
+ * ``debug_id`` - A debugging ID for logging in tracepoints.
+ * ``key`` - A printable string with no '/' characters in it that represents
+ the index key for the volume. The key is NUL-terminated and padded out to
+ a multiple of 4 bytes.
- * Release lookup data [mandatory]::
+ * ``key_hash`` - A hash of the index key. This should work out the same, no
+ matter the cpu arch and endianness.
- void (*lookup_complete)(struct fscache_object *object)
+ * ``coherency`` - A piece of coherency data that should be checked when the
+ volume is bound to in the cache.
- This method is called to ask the cache to release any resources it was
- using to perform a lookup.
+ * ``coherency_len`` - The amount of data in the coherency buffer.
- * Increment object refcount [mandatory]::
+Data Storage Cookies
+====================
- struct fscache_object *(*grab_object)(struct fscache_object *object)
+A volume is a logical group of data storage objects, each of which is
+represented to the network filesystem by a cookie. Cookies are represented in
+the API as objects of type::
- This method is called to increment the reference count on an object. It
- may fail (for instance if the cache is being withdrawn) by returning NULL.
- It should return the object pointer if successful.
+ struct fscache_cookie {
+ struct fscache_volume *volume;
+ void *cache_priv;
+ unsigned long flags;
+ unsigned int debug_id;
+ unsigned int inval_counter;
+ loff_t object_size;
+ u8 advice;
+ u32 key_hash;
+ u8 key_len;
+ u8 aux_len;
+ ...
+ };
+The fields in the cookie that are of interest to the cache backend are:
- * Lock/Unlock object [mandatory]::
+ * ``volume`` - The parent volume cookie.
- void (*lock_object)(struct fscache_object *object)
- void (*unlock_object)(struct fscache_object *object)
+ * ``cache_priv`` - A place for the cache to stash private data.
- These methods are used to exclusively lock an object. It must be possible
- to schedule with the lock held, so a spinlock isn't sufficient.
+ * ``flags`` - A collection of bit flags, including:
+ * FSCACHE_COOKIE_NO_DATA_TO_READ - There is no data available in the
+ cache to be read as the cookie has been created or invalidated.
- * Pin/Unpin object [optional]::
+ * FSCACHE_COOKIE_NEEDS_UPDATE - The coherency data and/or object size has
+ been changed and needs committing.
- int (*pin_object)(struct fscache_object *object)
- void (*unpin_object)(struct fscache_object *object)
+ * FSCACHE_COOKIE_LOCAL_WRITE - The netfs's data has been modified
+ locally, so the cache object may be in an incoherent state with respect
+ to the server.
- These methods are used to pin an object into the cache. Once pinned an
- object cannot be reclaimed to make space. Return -ENOSPC if there's not
- enough space in the cache to permit this.
+ * FSCACHE_COOKIE_HAVE_DATA - The backend should set this if it
+ successfully stores data into the cache.
+ * FSCACHE_COOKIE_RETIRED - The cookie was invalidated when it was
+ relinquished and the cached data should be discarded.
- * Check coherency state of an object [mandatory]::
+ * ``debug_id`` - A debugging ID for logging in tracepoints.
- int (*check_consistency)(struct fscache_object *object)
+ * ``inval_counter`` - The number of invalidations done on the cookie.
- This method is called to have the cache check the saved auxiliary data of
- the object against the netfs's idea of the state. 0 should be returned
- if they're consistent and -ESTALE otherwise. -ENOMEM and -ERESTARTSYS
- may also be returned.
+ * ``advice`` - Information about how the cookie is to be used.
- * Update object [mandatory]::
+ * ``key_hash`` - A hash of the index key. This should work out the same, no
+ matter the cpu arch and endianness.
- int (*update_object)(struct fscache_object *object)
+ * ``key_len`` - The length of the index key.
- This is called to update the index entry for the specified object. The
- new information should be in object->cookie->netfs_data. This can be
- obtained by calling object->cookie->def->get_aux()/get_attr().
+ * ``aux_len`` - The length of the coherency data buffer.
+Each cookie has an index key, which may be stored inline to the cookie or
+elsewhere. A pointer to this can be obtained by calling::
- * Invalidate data object [mandatory]::
+ void *fscache_get_key(struct fscache_cookie *cookie);
- int (*invalidate_object)(struct fscache_operation *op)
+The index key is a binary blob, the storage for which is padded out to a
+multiple of 4 bytes.
- This is called to invalidate a data object (as pointed to by op->object).
- All the data stored for this object should be discarded and an
- attr_changed operation should be performed. The caller will follow up
- with an object update operation.
+Each cookie also has a buffer for coherency data. This may also be inline or
+detached from the cookie and a pointer is obtained by calling::
- fscache_op_complete() must be called on op before returning.
+ void *fscache_get_aux(struct fscache_cookie *cookie);
- * Discard object [mandatory]::
- void (*drop_object)(struct fscache_object *object)
+Cookie Accounting
+=================
- This method is called to indicate that an object has been unbound from its
- cookie, and that the cache should release the object's resources and
- retire it if it's in state FSCACHE_OBJECT_RECYCLING.
+Data storage cookies are counted and this is used to block cache withdrawal
+completion until all objects have been destroyed. The following functions are
+provided to the cache to deal with that::
- This method should not attempt to release any references held by the
- caller. The caller will invoke the put_object() method as appropriate.
+ void fscache_count_object(struct fscache_cache *cache);
+ void fscache_uncount_object(struct fscache_cache *cache);
+ void fscache_wait_for_objects(struct fscache_cache *cache);
+The count function records the allocation of an object in a cache and the
+uncount function records its destruction. Warning: by the time the uncount
+function returns, the cache may have been destroyed.
- * Release object reference [mandatory]::
+The wait function can be used during the withdrawal procedure to wait for
+fscache to finish withdrawing all the objects in the cache. When it completes,
+there will be no remaining objects referring to the cache object or any volume
+objects.
- void (*put_object)(struct fscache_object *object)
- This method is used to discard a reference to an object. The object may
- be freed when all the references to it are released.
+Cache Management API
+====================
+The cache backend implements the cache management API by providing a table of
+operations that fscache can use to manage various aspects of the cache. These
+are held in a structure of type::
- * Synchronise a cache [mandatory]::
+ struct fscache_cache_ops {
+ const char *name;
+ ...
+ };
- void (*sync)(struct fscache_cache *cache)
+This contains a printable name for the cache backend driver plus a number of
+pointers to methods to allow fscache to request management of the cache:
- This is called to ask the backend to synchronise a cache with its backing
- device.
+ * Set up a volume cookie [optional]::
+ void (*acquire_volume)(struct fscache_volume *volume);
- * Dissociate a cache [mandatory]::
+ This method is called when a volume cookie is being created. The caller
+ holds a cache-level access pin to prevent the cache from going away for
+ the duration. This method should set up the resources to access a volume
+ in the cache and should not return until it has done so.
- void (*dissociate_pages)(struct fscache_cache *cache)
+ If successful, it can set ``cache_priv`` to its own data.
- This is called to ask a cache to perform any page dissociations as part of
- cache withdrawal.
+ * Clean up volume cookie [optional]::
- * Notification that the attributes on a netfs file changed [mandatory]::
+ void (*free_volume)(struct fscache_volume *volume);
- int (*attr_changed)(struct fscache_object *object);
+ This method is called when a volume cookie is being released if
+ ``cache_priv`` is set.
- This is called to indicate to the cache that certain attributes on a netfs
- file have changed (for example the maximum size a file may reach). The
- cache can read these from the netfs by calling the cookie's get_attr()
- method.
- The cache may use the file size information to reserve space on the cache.
- It should also call fscache_set_store_limit() to indicate to FS-Cache the
- highest byte it's willing to store for an object.
+ * Look up a cookie in the cache [mandatory]::
- This method may return -ve if an error occurred or the cache object cannot
- be expanded. In such a case, the object will be withdrawn from service.
+ bool (*lookup_cookie)(struct fscache_cookie *cookie);
- This operation is run asynchronously from FS-Cache's thread pool, and
- storage and retrieval operations from the netfs are excluded during the
- execution of this operation.
+ This method is called to look up/create the resources needed to access the
+ data storage for a cookie. It is called from a worker thread with a
+ volume-level access pin in the cache to prevent it from being withdrawn.
+ True should be returned if successful and false otherwise. If false is
+ returned, the withdraw_cookie op (see below) will be called.
- * Reserve cache space for an object's data [optional]::
+ If lookup fails, but the object could still be created (e.g. it hasn't
+ been cached before), then::
- int (*reserve_space)(struct fscache_object *object, loff_t size);
+ void fscache_cookie_lookup_negative(
+ struct fscache_cookie *cookie);
- This is called to request that cache space be reserved to hold the data
- for an object and the metadata used to track it. Zero size should be
- taken as request to cancel a reservation.
+ can be called to let the network filesystem proceed and start downloading
+ stuff whilst the cache backend gets on with the job of creating things.
- This should return 0 if successful, -ENOSPC if there isn't enough space
- available, or -ENOMEM or -EIO on other errors.
+ If successful, ``cookie->cache_priv`` can be set.
- The reservation may exceed the current size of the object, thus permitting
- future expansion. If the amount of space consumed by an object would
- exceed the reservation, it's permitted to refuse requests to allocate
- pages, but not required. An object may be pruned down to its reservation
- size if larger than that already.
+ * Withdraw an object without any cookie access counts held [mandatory]::
- * Request page be read from cache [mandatory]::
+ void (*withdraw_cookie)(struct fscache_cookie *cookie);
- int (*read_or_alloc_page)(struct fscache_retrieval *op,
- struct page *page,
- gfp_t gfp)
+ This method is called to withdraw a cookie from service. It will be
+ called when the cookie is relinquished by the netfs, withdrawn or culled
+ by the cache backend or closed after a period of non-use by fscache.
- This is called to attempt to read a netfs page from the cache, or to
- reserve a backing block if not. FS-Cache will have done as much checking
- as it can before calling, but most of the work belongs to the backend.
+ The caller doesn't hold any access pins, but it is called from a
+ non-reentrant work item to manage races between the various ways
+ withdrawal can occur.
- If there's no page in the cache, then -ENODATA should be returned if the
- backend managed to reserve a backing block; -ENOBUFS or -ENOMEM if it
- didn't.
+ The cookie will have the ``FSCACHE_COOKIE_RETIRED`` flag set on it if the
+ associated data is to be removed from the cache.
- If there is suitable data in the cache, then a read operation should be
- queued and 0 returned. When the read finishes, fscache_end_io() should be
- called.
- The fscache_mark_pages_cached() should be called for the page if any cache
- metadata is retained. This will indicate to the netfs that the page needs
- explicit uncaching. This operation takes a pagevec, thus allowing several
- pages to be marked at once.
+ * Change the size of a data storage object [mandatory]::
- The retrieval record pointed to by op should be retained for each page
- queued and released when I/O on the page has been formally ended.
- fscache_get/put_retrieval() are available for this purpose.
+ void (*resize_cookie)(struct netfs_cache_resources *cres,
+ loff_t new_size);
- The retrieval record may be used to get CPU time via the FS-Cache thread
- pool. If this is desired, the op->op.processor should be set to point to
- the appropriate processing routine, and fscache_enqueue_retrieval() should
- be called at an appropriate point to request CPU time. For instance, the
- retrieval routine could be enqueued upon the completion of a disk read.
- The to_do field in the retrieval record is provided to aid in this.
+ This method is called to inform the cache backend of a change in size of
+ the netfs file due to local truncation. The cache backend should make all
+ of the changes it needs to make before returning as this is done under the
+ netfs inode mutex.
- If an I/O error occurs, fscache_io_error() should be called and -ENOBUFS
- returned if possible or fscache_end_io() called with a suitable error
- code.
+ The caller holds a cookie-level access pin to prevent a race with
+ withdrawal and the netfs must have the cookie marked in-use to prevent
+ garbage collection or culling from removing any resources.
- fscache_put_retrieval() should be called after a page or pages are dealt
- with. This will complete the operation when all pages are dealt with.
+ * Invalidate a data storage object [mandatory]::
- * Request pages be read from cache [mandatory]::
+ bool (*invalidate_cookie)(struct fscache_cookie *cookie);
- int (*read_or_alloc_pages)(struct fscache_retrieval *op,
- struct list_head *pages,
- unsigned *nr_pages,
- gfp_t gfp)
+ This is called when the network filesystem detects a third-party
+ modification or when an O_DIRECT write is made locally. This requests
+ that the cache backend should throw away all the data in the cache for
+ this object and start afresh. It should return true if successful and
+ false otherwise.
- This is like the read_or_alloc_page() method, except it is handed a list
- of pages instead of one page. Any pages on which a read operation is
- started must be added to the page cache for the specified mapping and also
- to the LRU. Such pages must also be removed from the pages list and
- ``*nr_pages`` decremented per page.
+ On entry, new I O/operations are blocked. Once the cache is in a position
+ to accept I/O again, the backend should release the block by calling::
- If there was an error such as -ENOMEM, then that should be returned; else
- if one or more pages couldn't be read or allocated, then -ENOBUFS should
- be returned; else if one or more pages couldn't be read, then -ENODATA
- should be returned. If all the pages are dispatched then 0 should be
- returned.
+ void fscache_resume_after_invalidation(struct fscache_cookie *cookie);
+ If the method returns false, caching will be withdrawn for this cookie.
- * Request page be allocated in the cache [mandatory]::
- int (*allocate_page)(struct fscache_retrieval *op,
- struct page *page,
- gfp_t gfp)
+ * Prepare to make local modifications to the cache [mandatory]::
- This is like the read_or_alloc_page() method, except that it shouldn't
- read from the cache, even if there's data there that could be retrieved.
- It should, however, set up any internal metadata required such that
- the write_page() method can write to the cache.
+ void (*prepare_to_write)(struct fscache_cookie *cookie);
- If there's no backing block available, then -ENOBUFS should be returned
- (or -ENOMEM if there were other problems). If a block is successfully
- allocated, then the netfs page should be marked and 0 returned.
+ This method is called when the network filesystem finds that it is going
+ to need to modify the contents of the cache due to local writes or
+ truncations. This gives the cache a chance to note that a cache object
+ may be incoherent with respect to the server and may need writing back
+ later. This may also cause the cached data to be scrapped on later
+ rebinding if not properly committed.
- * Request pages be allocated in the cache [mandatory]::
+ * Begin an operation for the netfs lib [mandatory]::
- int (*allocate_pages)(struct fscache_retrieval *op,
- struct list_head *pages,
- unsigned *nr_pages,
- gfp_t gfp)
+ bool (*begin_operation)(struct netfs_cache_resources *cres,
+ enum fscache_want_state want_state);
- This is an multiple page version of the allocate_page() method. pages and
- nr_pages should be treated as for the read_or_alloc_pages() method.
+ This method is called when an I/O operation is being set up (read, write
+ or resize). The caller holds an access pin on the cookie and must have
+ marked the cookie as in-use.
+ If it can, the backend should attach any resources it needs to keep around
+ to the netfs_cache_resources object and return true.
- * Request page be written to cache [mandatory]::
+ If it can't complete the setup, it should return false.
- int (*write_page)(struct fscache_storage *op,
- struct page *page);
+ The want_state parameter indicates the state the caller needs the cache
+ object to be in and what it wants to do during the operation:
- This is called to write from a page on which there was a previously
- successful read_or_alloc_page() call or similar. FS-Cache filters out
- pages that don't have mappings.
+ * ``FSCACHE_WANT_PARAMS`` - The caller just wants to access cache
+ object parameters; it doesn't need to do data I/O yet.
- This method is called asynchronously from the FS-Cache thread pool. It is
- not required to actually store anything, provided -ENODATA is then
- returned to the next read of this page.
+ * ``FSCACHE_WANT_READ`` - The caller wants to read data.
- If an error occurred, then a negative error code should be returned,
- otherwise zero should be returned. FS-Cache will take appropriate action
- in response to an error, such as withdrawing this object.
+ * ``FSCACHE_WANT_WRITE`` - The caller wants to write to or resize the
+ cache object.
- If this method returns success then FS-Cache will inform the netfs
- appropriately.
+ Note that there won't necessarily be anything attached to the cookie's
+ cache_priv yet if the cookie is still being created.
- * Discard retained per-page metadata [mandatory]::
+Data I/O API
+============
- void (*uncache_page)(struct fscache_object *object, struct page *page)
+A cache backend provides a data I/O API by through the netfs library's ``struct
+netfs_cache_ops`` attached to a ``struct netfs_cache_resources`` by the
+``begin_operation`` method described above.
- This is called when a netfs page is being evicted from the pagecache. The
- cache backend should tear down any internal representation or tracking it
- maintains for this page.
+See the Documentation/filesystems/netfs_library.rst for a description.
-FS-Cache Utilities
-==================
+Miscellaneous Functions
+=======================
FS-Cache provides some utilities that a cache backend may make use of:
* Note occurrence of an I/O error in a cache::
- void fscache_io_error(struct fscache_cache *cache)
+ void fscache_io_error(struct fscache_cache *cache);
- This tells FS-Cache that an I/O error occurred in the cache. After this
- has been called, only resource dissociation operations (object and page
- release) will be passed from the netfs to the cache backend for the
- specified cache.
+ This tells FS-Cache that an I/O error occurred in the cache. This
+ prevents any new I/O from being started on the cache.
This does not actually withdraw the cache. That must be done separately.
+ * Note cessation of caching on a cookie due to failure::
- * Invoke the retrieval I/O completion function::
-
- void fscache_end_io(struct fscache_retrieval *op, struct page *page,
- int error);
-
- This is called to note the end of an attempt to retrieve a page. The
- error value should be 0 if successful and an error otherwise.
-
-
- * Record that one or more pages being retrieved or allocated have been dealt
- with::
-
- void fscache_retrieval_complete(struct fscache_retrieval *op,
- int n_pages);
-
- This is called to record the fact that one or more pages have been dealt
- with and are no longer the concern of this operation. When the number of
- pages remaining in the operation reaches 0, the operation will be
- completed.
-
-
- * Record operation completion::
-
- void fscache_op_complete(struct fscache_operation *op);
-
- This is called to record the completion of an operation. This deducts
- this operation from the parent object's run state, potentially permitting
- one or more pending operations to start running.
-
-
- * Set highest store limit::
-
- void fscache_set_store_limit(struct fscache_object *object,
- loff_t i_size);
-
- This sets the limit FS-Cache imposes on the highest byte it's willing to
- try and store for a netfs. Any page over this limit is automatically
- rejected by fscache_read_alloc_page() and co with -ENOBUFS.
-
-
- * Mark pages as being cached::
-
- void fscache_mark_pages_cached(struct fscache_retrieval *op,
- struct pagevec *pagevec);
-
- This marks a set of pages as being cached. After this has been called,
- the netfs must call fscache_uncache_page() to unmark the pages.
-
-
- * Perform coherency check on an object::
-
- enum fscache_checkaux fscache_check_aux(struct fscache_object *object,
- const void *data,
- uint16_t datalen);
-
- This asks the netfs to perform a coherency check on an object that has
- just been looked up. The cookie attached to the object will determine the
- netfs to use. data and datalen should specify where the auxiliary data
- retrieved from the cache can be found.
-
- One of three values will be returned:
-
- FSCACHE_CHECKAUX_OKAY
- The coherency data indicates the object is valid as is.
-
- FSCACHE_CHECKAUX_NEEDS_UPDATE
- The coherency data needs updating, but otherwise the object is
- valid.
-
- FSCACHE_CHECKAUX_OBSOLETE
- The coherency data indicates that the object is obsolete and should
- be discarded.
-
-
- * Initialise a freshly allocated object::
-
- void fscache_object_init(struct fscache_object *object);
-
- This initialises all the fields in an object representation.
-
-
- * Indicate the destruction of an object::
-
- void fscache_object_destroyed(struct fscache_cache *cache);
-
- This must be called to inform FS-Cache that an object that belonged to a
- cache has been destroyed and deallocated. This will allow continuation
- of the cache withdrawal process when it is stopped pending destruction of
- all the objects.
-
-
- * Indicate negative lookup on an object::
-
- void fscache_object_lookup_negative(struct fscache_object *object);
-
- This is called to indicate to FS-Cache that a lookup process for an object
- found a negative result.
-
- This changes the state of an object to permit reads pending on lookup
- completion to go off and start fetching data from the netfs server as it's
- known at this point that there can't be any data in the cache.
-
- This may be called multiple times on an object. Only the first call is
- significant - all subsequent calls are ignored.
-
-
- * Indicate an object has been obtained::
-
- void fscache_obtained_object(struct fscache_object *object);
-
- This is called to indicate to FS-Cache that a lookup process for an object
- produced a positive result, or that an object was created. This should
- only be called once for any particular object.
-
- This changes the state of an object to indicate:
-
- (1) if no call to fscache_object_lookup_negative() has been made on
- this object, that there may be data available, and that reads can
- now go and look for it; and
-
- (2) that writes may now proceed against this object.
-
-
- * Indicate that object lookup failed::
-
- void fscache_object_lookup_error(struct fscache_object *object);
-
- This marks an object as having encountered a fatal error (usually EIO)
- and causes it to move into a state whereby it will be withdrawn as soon
- as possible.
-
-
- * Indicate that a stale object was found and discarded::
-
- void fscache_object_retrying_stale(struct fscache_object *object);
-
- This is called to indicate that the lookup procedure found an object in
- the cache that the netfs decided was stale. The object has been
- discarded from the cache and the lookup will be performed again.
-
-
- * Indicate that the caching backend killed an object::
-
- void fscache_object_mark_killed(struct fscache_object *object,
- enum fscache_why_object_killed why);
-
- This is called to indicate that the cache backend preemptively killed an
- object. The why parameter should be set to indicate the reason:
+ void fscache_caching_failed(struct fscache_cookie *cookie);
- FSCACHE_OBJECT_IS_STALE
- - the object was stale and needs discarding.
+ This notes that a the caching that was being done on a cookie failed in
+ some way, for instance the backing storage failed to be created or
+ invalidation failed and that no further I/O operations should take place
+ on it until the cache is reset.
- FSCACHE_OBJECT_NO_SPACE
- - there was insufficient cache space
+ * Count I/O requests::
- FSCACHE_OBJECT_WAS_RETIRED
- - the object was retired when relinquished.
+ void fscache_count_read(void);
+ void fscache_count_write(void);
- FSCACHE_OBJECT_WAS_CULLED
- - the object was culled to make space.
+ These record reads and writes from/to the cache. The numbers are
+ displayed in /proc/fs/fscache/stats.
+ * Count out-of-space errors::
- * Get and release references on a retrieval record::
+ void fscache_count_no_write_space(void);
+ void fscache_count_no_create_space(void);
- void fscache_get_retrieval(struct fscache_retrieval *op);
- void fscache_put_retrieval(struct fscache_retrieval *op);
+ These record ENOSPC errors in the cache, divided into failures of data
+ writes and failures of filesystem object creations (e.g. mkdir).
- These two functions are used to retain a retrieval record while doing
- asynchronous data retrieval and block allocation.
+ * Count objects culled::
+ void fscache_count_culled(void);
- * Enqueue a retrieval record for processing::
+ This records the culling of an object.
- void fscache_enqueue_retrieval(struct fscache_retrieval *op);
+ * Get the cookie from a set of cache resources::
- This enqueues a retrieval record for processing by the FS-Cache thread
- pool. One of the threads in the pool will invoke the retrieval record's
- op->op.processor callback function. This function may be called from
- within the callback function.
+ struct fscache_cookie *fscache_cres_cookie(struct netfs_cache_resources *cres)
+ Pull a pointer to the cookie from the cache resources. This may return a
+ NULL cookie if no cookie was set.
- * List of object state names::
- const char *fscache_object_states[];
+API Function Reference
+======================
- For debugging purposes, this may be used to turn the state that an object
- is in into a text string for display purposes.

- (5) Cookies are used to represent indices, files and other objects to the

- indices.
-
- (7) Data I/O is done direct to and from the netfs's pages. The netfs

- saying whether a match was made or not, this can also specify that an
- entry should be updated or deleted.

-In the example above, you can see two netfs's being backed: NFS and AFS. These
-have different index hierarchies:
-
- * The NFS primary index contains per-server indices. Each server index is
- indexed by NFS file handles to get data file objects. Each data file
- objects can have an array of pages, but may also have further child
- objects, such as extended attributes and directory entries. Extended
- attribute objects themselves have page-array contents.
-
- * The AFS primary index contains per-cell indices. Each cell index contains
- per-logical-volume indices. Each of volume index contains up to three
- indices for the read-write, read-only and backup mirrors of those volumes.
- Each of these contains vnode data file objects, each of which contains an
- array of pages.
-
-The very top index is the FS-Cache master index in which individual netfs's
-have entries.
-
-Any index object may reside in more than one cache, provided it only has index
-children. Any index with non-index object children will be assumed to only
-reside in one cache.
+ * There are three types of cookie: cache, volume and data file cookies.
+ Cache cookies represent the cache as a whole and are not normally visible
+ to the netfs; the netfs gets a volume cookie to represent a collection of
+ files (typically something that a netfs would get for a superblock); and
+ data file cookies are used to cache data (something that would be got for
+ an inode).
+
+ * Volumes are matched using a key. This is a printable string that is used
+ to encode all the information that might be needed to distinguish one
+ superblock, say, from another. This would be a compound of things like
+ cell name or server address, volume name or share path. It must be a
+ valid pathname.
+
+ * Cookies are matched using a key. This is a binary blob and is used to
+ represent the object within a volume (so the volume key need not form
+ part of the blob). This might include things like an inode number and
+ uniquifier or a file handle.
+
+ * Cookie resources are set up and pinned by marking the cookie in-use.
+ This prevents the backing resources from being culled. Timed garbage
+ collection is employed to eliminate cookies that haven't been used for a
+ short while, thereby reducing resource overload. This is intended to be
+ used when a file is opened or closed.
+
+ A cookie can be marked in-use multiple times simultaneously; each mark
+ must be unused.
+
+ * Begin/end access functions are provided to delay cache withdrawal for the
+ duration of an operation and prevent structs from being freed whilst
+ we're looking at them.
+
+ * Data I/O is done by asynchronous DIO to/from a buffer described by the
+ netfs using an iov_iter.
+
+ * An invalidation facility is available to discard data from the cache and
+ to deal with I/O that's in progress that is accessing old data.
+
+ * Cookies can be "retired" upon release, thereby causing the object to be
+ removed from the cache.

-FS-Cache Network Filesystem API

+==============================
+Network Filesystem Caching API
+==============================
-There's an API by which a network filesystem can make use of the FS-Cache
-facilities. This is based around a number of principles:
+Fscache provides an API by which a network filesystem can make use of local
+caching facilities. The API is arranged around a number of principles:
- (1) Caches can store a number of different object types. There are two main
- object types: indices and files. The first is a special type used by
- FS-Cache to make finding objects faster and to make retiring of groups of
- objects easier.
+ (1) A cache is logically organised into volumes and data storage objects
+ within those volumes.
- (2) Every index, file or other object is represented by a cookie. This cookie
- may or may not have anything associated with it, but the netfs doesn't
- need to care.
+ (2) Volumes and data storage objects are represented by various types of
+ cookie.
- (3) Barring the top-level index (one entry per cached netfs), the index
- hierarchy for each netfs is structured according the whim of the netfs.
+ (3) Cookies have keys that distinguish them from their peers.
-This API is declared in <linux/fscache.h>.
+ (4) Cookies have coherency data that allows a cache to determine if the
+ cached data is still valid.

-
-Network Filesystem Definition
-=============================
-
-FS-Cache needs a description of the network filesystem. This is specified
-using a record of the following structure::
-
- struct fscache_netfs {
- uint32_t version;
- const char *name;
- struct fscache_cookie *primary_index;
- ...
- };
-
-This first two fields should be filled in before registration, and the third
-will be filled in by the registration function; any other fields should just be
-ignored and are for internal use only.
-
-The fields are:
-
- (1) The name of the netfs (used as the key in the toplevel index).
-
- (2) The version of the netfs (if the name matches but the version doesn't, the
- entire in-cache hierarchy for this netfs will be scrapped and begun
- afresh).
-
- (3) The cookie representing the primary index will be allocated according to
- another parameter passed into the registration function.
-
-For example, kAFS (linux/fs/afs/) uses the following definitions to describe
-itself::
-
- struct fscache_netfs afs_cache_netfs = {
- .version = 0,
- .name = "afs",
- };
-
-
-Index Definition
-================
-
-Indices are used for two purposes:
-
- (1) To aid the finding of a file based on a series of keys (such as AFS's
- "cell", "volume ID", "vnode ID").
-
- (2) To make it easier to discard a subset of all the files cached based around
- a particular key - for instance to mirror the removal of an AFS volume.
-
-However, since it's unlikely that any two netfs's are going to want to define
-their index hierarchies in quite the same way, FS-Cache tries to impose as few
-restraints as possible on how an index is structured and where it is placed in
-the tree. The netfs can even mix indices and data files at the same level, but
-it's not recommended.
-
-Each index entry consists of a key of indeterminate length plus some auxiliary
-data, also of indeterminate length.
-
-There are some limits on indices:
-
- (1) Any index containing non-index objects should be restricted to a single
- cache. Any such objects created within an index will be created in the
- first cache only. The cache in which an index is created can be
- controlled by cache tags (see below).
-
- (2) The entry data must be atomically journallable, so it is limited to about
- 400 bytes at present. At least 400 bytes will be available.
-
- (3) The depth of the index tree should be judged with care as the search
- function is recursive. Too many layers will run the kernel out of stack.
-
-
-Object Definition
-=================
-
-To define an object, a structure of the following type should be filled out::
-
- struct fscache_cookie_def
- {
- uint8_t name[16];
- uint8_t type;
-
- struct fscache_cache_tag *(*select_cache)(
- const void *parent_netfs_data,
- const void *cookie_netfs_data);
-
- enum fscache_checkaux (*check_aux)(void *cookie_netfs_data,
- const void *data,
- uint16_t datalen,
- loff_t object_size);
-
- void (*get_context)(void *cookie_netfs_data, void *context);
-
- void (*put_context)(void *cookie_netfs_data, void *context);
-
- void (*mark_pages_cached)(void *cookie_netfs_data,
- struct address_space *mapping,
- struct pagevec *cached_pvec);
- };
-
-This has the following fields:
-
- (1) The type of the object [mandatory].
-
- This is one of the following values:
-
- FSCACHE_COOKIE_TYPE_INDEX
- This defines an index, which is a special FS-Cache type.
-
- FSCACHE_COOKIE_TYPE_DATAFILE
- This defines an ordinary data file.
-
- Any other value between 2 and 255
- This defines an extraordinary object such as an XATTR.
-
- (2) The name of the object type (NUL terminated unless all 16 chars are used)
- [optional].
-
- (3) A function to select the cache in which to store an index [optional].
-
- This function is invoked when an index needs to be instantiated in a cache
- during the instantiation of a non-index object. Only the immediate index
- parent for the non-index object will be queried. Any indices above that
- in the hierarchy may be stored in multiple caches. This function does not
- need to be supplied for any non-index object or any index that will only
- have index children.
-
- If this function is not supplied or if it returns NULL then the first
- cache in the parent's list will be chosen, or failing that, the first
- cache in the master list.
-
- (4) A function to check the auxiliary data [optional].
-
- This function will be called to check that a match found in the cache for
- this object is valid. For instance with AFS it could check the auxiliary
- data against the data version number returned by the server to determine
- whether the index entry in a cache is still valid.
-
- If this function is absent, it will be assumed that matching objects in a
- cache are always valid.
-
- The function is also passed the cache's idea of the object size and may
- use this to manage coherency also.
-
- If present, the function should return one of the following values:
-
- FSCACHE_CHECKAUX_OKAY
- - the entry is okay as is
-
- FSCACHE_CHECKAUX_NEEDS_UPDATE
- - the entry requires update
-
- FSCACHE_CHECKAUX_OBSOLETE
- - the entry should be deleted
+ (5) I/O is done asynchronously where possible.
- This function can also be used to extract data from the auxiliary data in
- the cache and copy it into the netfs's structures.
+This API is used by::
- (5) A pair of functions to manage contexts for the completion callback
- [optional].
+ #include <linux/fscache.h>.
- The cache read/write functions are passed a context which is then passed
- to the I/O completion callback function. To ensure this context remains
- valid until after the I/O completion is called, two functions may be
- provided: one to get an extra reference on the context, and one to drop a
- reference to it.
-
- If the context is not used or is a type of object that won't go out of
- scope, then these functions are not required. These functions are not
- required for indices as indices may not contain data. These functions may
- be called in interrupt context and so may not sleep.
-
- (6) A function to mark a page as retaining cache metadata [optional].
-
- This is called by the cache to indicate that it is retaining in-memory
- information for this page and that the netfs should uncache the page when
- it has finished. This does not indicate whether there's data on the disk
- or not. Note that several pages at once may be presented for marking.
-
- The PG_fscache bit is set on the pages before this function would be
- called, so the function need not be provided if this is sufficient.
-
- This function is not required for indices as they're not permitted data.
-
- (7) A function to unmark all the pages retaining cache metadata [mandatory].
-
- This is called by FS-Cache to indicate that a backing store is being
- unbound from a cookie and that all the marks on the pages should be
- cleared to prevent confusion. Note that the cache will have torn down all
- its tracking information so that the pages don't need to be explicitly
- uncached.
-
- This function is not required for indices as they're not permitted data.
-
-
-Network Filesystem (Un)registration
-===================================
-
-The first step is to declare the network filesystem to the cache. This also
-involves specifying the layout of the primary index (for AFS, this would be the
-"cell" level).
-
-The registration function is::
-
- int fscache_register_netfs(struct fscache_netfs *netfs);
-
-It just takes a pointer to the netfs definition. It returns 0 or an error as
-appropriate.
-
-For kAFS, registration is done as follows::
-
- ret = fscache_register_netfs(&afs_cache_netfs);
-
-The last step is, of course, unregistration::
-
- void fscache_unregister_netfs(struct fscache_netfs *netfs);
-
-
-Cache Tag Lookup
-================
-
-FS-Cache permits the use of more than one cache. To permit particular index
-subtrees to be bound to particular caches, the second step is to look up cache
-representation tags. This step is optional; it can be left entirely up to
-FS-Cache as to which cache should be used. The problem with doing that is that
-FS-Cache will always pick the first cache that was registered.
-
-To get the representation for a named tag::
-
- struct fscache_cache_tag *fscache_lookup_cache_tag(const char *name);
-
-This takes a text string as the name and returns a representation of a tag. It
-will never return an error. It may return a dummy tag, however, if it runs out
-of memory; this will inhibit caching with this tag.
-
-Any representation so obtained must be released by passing it to this function::
-
- void fscache_release_cache_tag(struct fscache_cache_tag *tag);
+.. This document contains the following sections:
-The tag will be retrieved by FS-Cache when it calls the object definition

+
+
+Overview
+========
+
+The fscache hierarchy is organised on two levels from a network filesystem's
+point of view. The upper level represents "volumes" and the lower level
+represents "data storage objects". These are represented by two types of
+cookie, hereafter referred to as "volume cookies" and "cookies".
+
+A network filesystem acquires a volume cookie for a volume using a volume key,
+which represents all the information that defines that volume (e.g. cell name
+or server address, volume ID or share name). This must be rendered as a
+printable string that can be used as a directory name (ie. no '/' characters
+and shouldn't begin with a '.'). The maximum name length is one less than the
+maximum size of a filename component (allowing the cache backend one char for
+its own purposes).
+
+A filesystem would typically have a volume cookie for each superblock.
+
+The filesystem then acquires a cookie for each file within that volume using an
+object key. Object keys are binary blobs and only need to be unique within
+their parent volume. The cache backend is reponsible for rendering the binary
+blob into something it can use and may employ hash tables, trees or whatever to
+improve its ability to find an object. This is transparent to the network
+filesystem.
+
+A filesystem would typically have a cookie for each inode, and would acquire it
+in iget and relinquish it when evicting the cookie.
+
+Once it has a cookie, the filesystem needs to mark the cookie as being in use.
+This causes fscache to send the cache backend off to look up/create resources
+for the cookie in the background, to check its coherency and, if necessary, to
+mark the object as being under modification.
+
+A filesystem would typically "use" the cookie in its file open routine and
+unuse it in file release and it needs to use the cookie around calls to
+truncate the cookie locally. It *also* needs to use the cookie when the
+pagecache becomes dirty and unuse it when writeback is complete. This is
+slightly tricky, and provision is made for it.
+
+When performing a read, write or resize on a cookie, the filesystem must first
+begin an operation. This copies the resources into a holding struct and puts
+extra pins into the cache to stop cache withdrawal from tearing down the
+structures being used. The actual operation can then be issued and conflicting
+invalidations can be detected upon completion.
+
+The filesystem is expected to use netfslib to access the cache, but that's not
+actually required and it can use the fscache I/O API directly.
+
+
+Volume Registration
+===================
+
+The first step for a network filsystem is to acquire a volume cookie for the
+volume it wants to access::
+
+ struct fscache_volume *
+ fscache_acquire_volume(const char *volume_key,
+ const char *cache_name,
+ const void *coherency_data,
+ size_t coherency_len);
+
+This function creates a volume cookie with the specified volume key as its name
+and notes the coherency data.
+
+The volume key must be a printable string with no '/' characters in it. It
+should begin with the name of the filesystem and should be no longer than 254
+characters. It should uniquely represent the volume and will be matched with
+what's stored in the cache.
+
+The caller may also specify the name of the cache to use. If specified,
+fscache will look up or create a cache cookie of that name and will use a cache
+of that name if it is online or comes online. If no cache name is specified,
+it will use the first cache that comes to hand and set the name to that.
+
+The specified coherency data is stored in the cookie and will be matched
+against coherency data stored on disk. The data pointer may be NULL if no data
+is provided. If the coherency data doesn't match, the entire cache volume will
+be invalidated.
+
+This function can return errors such as EBUSY if the volume key is already in
+use by an acquired volume or ENOMEM if an allocation failure occured. It may
+also return a NULL volume cookie if fscache is not enabled. It is safe to
+pass a NULL cookie to any function that takes a volume cookie. This will
+cause that function to do nothing.
+
+
+When the network filesystem has finished with a volume, it should relinquish it
+by calling::
+
+ void fscache_relinquish_volume(struct fscache_volume *volume,
+ const void *coherency_data,
+ bool invalidate);
+
+This will cause the volume to be committed or removed, and if sealed the
+coherency data will be set to the value supplied. The amount of coherency data
+must match the length specified when the volume was acquired. Note that all
+data cookies obtained in this volume must be relinquished before the volume is
+relinquished.
-Index Registration
-==================
+Data File Registration
+======================
-The third step is to inform FS-Cache about part of an index hierarchy that can
-be used to locate files. This is done by requesting a cookie for each index in
-the path to the file::
+Once it has a volume cookie, a network filesystem can use it to acquire a
+cookie for data storage::
struct fscache_cookie *
- fscache_acquire_cookie(struct fscache_cookie *parent,
- const struct fscache_object_def *def,
+ fscache_acquire_cookie(struct fscache_volume *volume,
+ u8 advice,
const void *index_key,
size_t index_key_len,
const void *aux_data,
size_t aux_data_len,
- void *netfs_data,
- loff_t object_size,
- bool enable);
+ loff_t object_size)
-This function creates an index entry in the index represented by parent,
-filling in the index entry by calling the operations pointed to by def.
+This creates the cookie in the volume using the specified index key. The index
+key is a binary blob of the given length and must be unique for the volume.
+This is saved into the cookie. There are no restrictions on the content, but
+its length shouldn't exceed about three quarters of the maximum filename length
+to allow for encoding.
-A unique key that represents the object within the parent must be pointed to by
-index_key and is of length index_key_len.
+The caller should also pass in a piece of coherency data in aux_data. A buffer
+of size aux_data_len will be allocated and the coherency data copied in. It is
+assumed that the size is invariant over time. The coherency data is used to
+check the validity of data in the cache. Functions are provided by which the
+coherency data can be updated.
-An optional blob of auxiliary data that is to be stored within the cache can be
-pointed to with aux_data and should be of length aux_data_len. This would
-typically be used for storing coherency data.
+The file size of the object being cached should also be provided. This may be
+used to trim the data and will be stored with the coherency data.
-The netfs may pass an arbitrary value in netfs_data and this will be presented
-to it in the event of any calling back. This may also be used in tracing or
-logging of messages.
+This function never returns an error, though it may return a NULL cookie on
+allocation failure or if fscache is not enabled. It is safe to pass in a NULL
+volume cookie and pass the NULL cookie returned to any function that takes it.
+This will cause that function to do nothing.
-The cache tracks the size of the data attached to an object and this set to be
-object_size. For indices, this should be 0. This value will be passed to the
-->check_aux() callback.
-Note that this function never returns an error - all errors are handled
-internally. It may, however, return NULL to indicate no cookie. It is quite
-acceptable to pass this token back to this function as the parent to another
-acquisition (or even to the relinquish cookie, read page and write page
-functions - see below).
+When the network filesystem has finished with a cookie, it should relinquish it
+by calling::
-Note also that no indices are actually created in a cache until a non-index
-object needs to be created somewhere down the hierarchy. Furthermore, an index
-may be created in several different caches independently at different times.
-This is all handled transparently, and the netfs doesn't see any of it.
+ void fscache_relinquish_cookie(struct fscache_cookie *cookie,
+ bool retire);
-A cookie will be created in the disabled state if enabled is false. A cookie
-must be enabled to do anything with it. A disabled cookie can be enabled by
-calling fscache_enable_cookie() (see below).
+This will cause fscache to either commit the storage backing the cookie or
+delete it.
-For example, with AFS, a cell would be added to the primary index. This index
-entry would have a dependent inode containing volume mappings within this cell::
- cell->cache =
- fscache_acquire_cookie(afs_cache_netfs.primary_index,
- &afs_cell_cache_index_def,
- cell->name, strlen(cell->name),
- NULL, 0,
- cell, 0, true);
+Marking A Cookie In-Use
+=======================
-And then a particular volume could be added to that index by ID, creating
-another index for vnodes (AFS inode equivalents)::
+Once a cookie has been acquired by a network filesystem, the filesystem should
+tell fscache when it intends to use the cookie (typically done on file open)
+and should say when it has finished with it (typically on file close)::
- volume->cache =
- fscache_acquire_cookie(volume->cell->cache,
- &afs_volume_cache_index_def,
- &volume->vid, sizeof(volume->vid),
- NULL, 0,
- volume, 0, true);
+ void fscache_use_cookie(struct fscache_cookie *cookie,
+ bool will_modify);
+ void fscache_unuse_cookie(struct fscache_cookie *cookie,
+ const void *aux_data,
+ const loff_t *object_size);
+The *use* function tells fscache that it will use the cookie and, additionally,
+indicate if the user is intending to modify the contents locally. If not yet
+done, this will trigger the cache backend to go and gather the resources it
+needs to access/store data in the cache. This is done in the background, and
+so may not be complete by the time the function returns.
-Data File Registration
-======================
+The *unuse* function indicates that a filesystem has finished using a cookie.
+It optionally updates the stored coherency data and object size and then
+decreases the in-use counter. When the last user unuses the cookie, it is
+scheduled for garbage collection. If not reused within a short time, the
+resources will be released to reduce system resource consumption.
-The fourth step is to request a data file be created in the cache. This is
-identical to index cookie acquisition. The only difference is that the type in
-the object definition should be something other than index type::
+A cookie must be marked in-use before it can be accessed for read, write or
+resize - and an in-use mark must be kept whilst there is dirty data in the
+pagecache in order to avoid an oops due to trying to open a file during process
+exit.
- vnode->cache =
- fscache_acquire_cookie(volume->cache,
- &afs_vnode_cache_object_def,
- &key, sizeof(key),
- &aux, sizeof(aux),
- vnode, vnode->status.size, true);
+Note that in-use marks are cumulative. For each time a cookie is marked
+in-use, it must be unused.
-Miscellaneous Object Registration
+Resizing A Data File (Truncation)
=================================
-An optional step is to request an object of miscellaneous type be created in
-the cache. This is almost identical to index cookie acquisition. The only
-difference is that the type in the object definition should be something other
-than index type. While the parent object could be an index, it's more likely
-it would be some other type of object such as a data file::
-
- xattr->cache =
- fscache_acquire_cookie(vnode->cache,
- &afs_xattr_cache_object_def,
- &xattr->name, strlen(xattr->name),
- NULL, 0,
- xattr, strlen(xattr->val), true);
-
-Miscellaneous objects might be used to store extended attributes or directory
-entries for example.
-
-
-Setting the Data File Size
-==========================
+If a network filesystem file is resized locally by truncation, the following
+should be called to notify the cache::
-The fifth step is to set the physical attributes of the file, such as its size.
-This doesn't automatically reserve any space in the cache, but permits the
-cache to adjust its metadata for data tracking appropriately::
+ void fscache_resize_cookie(struct fscache_cookie *cookie,
+ loff_t new_size);
- int fscache_attr_changed(struct fscache_cookie *cookie);
+The caller must have first marked the cookie in-use. The cookie and the new
+size are passed in and the cache is synchronously resized. This is expected to
+be called from ``->setattr()`` inode operation under the inode lock.
-The cache will return -ENOBUFS if there is no backing cache or if there is no
-space to allocate any extra metadata required in the cache.
-Note that attempts to read or write data pages in the cache over this size may
-be rebuffed with -ENOBUFS.
+Data I/O API
+============
-This operation schedules an attribute adjustment to happen asynchronously at
-some point in the future, and as such, it may happen after the function returns
-to the caller. The attribute adjustment excludes read and write operations.
+To do data I/O operations directly through a cookie, the following functions
+are available::

-Page alloc/read/write
-=====================
+The *begin* function sets up an operation, attaching the resources required to
+the cache resources block from the cookie. Assuming it doesn't return an error
+(for instance, it will return -ENOBUFS if given a NULL cookie, but otherwise do
+nothing), then one of the other two functions can be issued.
-And the sixth step is to store and retrieve pages in the cache. There are
-three functions that are used to do this.
+The *read* and *write* functions initiate a direct-IO operation. Both take the
+previously set up cache resources block, an indication of the start file
+position, and an I/O iterator that describes buffer and indicates the amount of
+data.
-Note:
+The read function also takes a parameter to indicate how it should handle a
+partially populated region (a hole) in the disk content. This may be to ignore
+it, skip over an initial hole and place zeros in the buffer or give an error.
- (1) A page should not be re-read or re-allocated without uncaching it first.
-
- (2) A read or allocated page must be uncached when the netfs page is released
- from the pagecache.
-
- (3) A page should only be written to the cache if previous read or allocated.
-
-This permits the cache to maintain its page tracking in proper order.
-
-
-PAGE READ
----------
-
-Firstly, the netfs should ask FS-Cache to examine the caches and read the
-contents cached for a particular page of a particular file if present, or else
-allocate space to store the contents if not::
+The read and write functions can be given an optional termination function that
+will be run on completion::
typedef
- void (*fscache_rw_complete_t)(struct page *page,
- void *context,
- int error);
-
- int fscache_read_or_alloc_page(struct fscache_cookie *cookie,
- struct page *page,
- fscache_rw_complete_t end_io_func,
- void *context,
- gfp_t gfp);
-
-The cookie argument must specify a cookie for an object that isn't an index,
-the page specified will have the data loaded into it (and is also used to
-specify the page number), and the gfp argument is used to control how any
-memory allocations made are satisfied.
-
-If the cookie indicates the inode is not cached:
-
- (1) The function will return -ENOBUFS.
-
-Else if there's a copy of the page resident in the cache:
-
- (1) The mark_pages_cached() cookie operation will be called on that page.
+ void (*netfs_io_terminated_t)(void *priv, ssize_t transferred_or_error,
+ bool was_async);
- (2) The function will submit a request to read the data from the cache's
- backing device directly into the page specified.
+If a termination function is given, the operation will be run asynchronously
+and the termination function will be called upon completion. If not given, the
+operation will be run synchronously. Note that in the asynchronous case, it is
+possible for the operation to complete before the function returns.
- (3) The function will return 0.
+Both the read and write functions end the operation when they complete,
+detaching any pinned resources.
- (4) When the read is complete, end_io_func() will be invoked with:
+The read operation will fail with ESTALE if invalidation occurred whilst the
+operation was ongoing.
- * The netfs data supplied when the cookie was created.
- * The page descriptor.
+Data File Coherency
+===================
- * The context argument passed to the above function. This will be
- maintained with the get_context/put_context functions mentioned above.
-
- * An argument that's 0 on success or negative for an error code.
-
- If an error occurs, it should be assumed that the page contains no usable
- data. fscache_readpages_cancel() may need to be called.
-
- end_io_func() will be called in process context if the read is results in
- an error, but it might be called in interrupt context if the read is
- successful.
-
-Otherwise, if there's not a copy available in cache, but the cache may be able
-to store the page:
-
- (1) The mark_pages_cached() cookie operation will be called on that page.
-
- (2) A block may be reserved in the cache and attached to the object at the
- appropriate place.
-
- (3) The function will return -ENODATA.
-
-This function may also return -ENOMEM or -EINTR, in which case it won't have
-read any data from the cache.
-
-
-Page Allocate
--------------
-
-Alternatively, if there's not expected to be any data in the cache for a page
-because the file has been extended, a block can simply be allocated instead::
-
- int fscache_alloc_page(struct fscache_cookie *cookie,
- struct page *page,
- gfp_t gfp);
-
-This is similar to the fscache_read_or_alloc_page() function, except that it
-never reads from the cache. It will return 0 if a block has been allocated,
-rather than -ENODATA as the other would. One or the other must be performed
-before writing to the cache.
-
-The mark_pages_cached() cookie operation will be called on the page if
-successful.
-
-
-Page Write
-----------
-
-Secondly, if the netfs changes the contents of the page (either due to an
-initial download or if a user performs a write), then the page should be
-written back to the cache::
-
- int fscache_write_page(struct fscache_cookie *cookie,
- struct page *page,
- loff_t object_size,
- gfp_t gfp);
-
-The cookie argument must specify a data file cookie, the page specified should
-contain the data to be written (and is also used to specify the page number),
-object_size is the revised size of the object and the gfp argument is used to
-control how any memory allocations made are satisfied.
-
-The page must have first been read or allocated successfully and must not have
-been uncached before writing is performed.
-
-If the cookie indicates the inode is not cached then:
-
- (1) The function will return -ENOBUFS.
-
-Else if space can be allocated in the cache to hold this page:
-
- (1) PG_fscache_write will be set on the page.
-
- (2) The function will submit a request to write the data to cache's backing
- device directly from the page specified.
-
- (3) The function will return 0.
-
- (4) When the write is complete PG_fscache_write is cleared on the page and
- anyone waiting for that bit will be woken up.
-
-Else if there's no space available in the cache, -ENOBUFS will be returned. It
-is also possible for the PG_fscache_write bit to be cleared when no write took
-place if unforeseen circumstances arose (such as a disk error).
-
-Writing takes place asynchronously.
-
-
-Multiple Page Read
-------------------
-
-A facility is provided to read several pages at once, as requested by the
-readpages() address space operation::
-
- int fscache_read_or_alloc_pages(struct fscache_cookie *cookie,
- struct address_space *mapping,
- struct list_head *pages,
- int *nr_pages,
- fscache_rw_complete_t end_io_func,
- void *context,
- gfp_t gfp);
-
-This works in a similar way to fscache_read_or_alloc_page(), except:
-
- (1) Any page it can retrieve data for is removed from pages and nr_pages and
- dispatched for reading to the disk. Reads of adjacent pages on disk may
- be merged for greater efficiency.
-
- (2) The mark_pages_cached() cookie operation will be called on several pages
- at once if they're being read or allocated.
-
- (3) If there was an general error, then that error will be returned.
-
- Else if some pages couldn't be allocated or read, then -ENOBUFS will be
- returned.
-
- Else if some pages couldn't be read but were allocated, then -ENODATA will
- be returned.
-
- Otherwise, if all pages had reads dispatched, then 0 will be returned, the
- list will be empty and ``*nr_pages`` will be 0.
-
- (4) end_io_func will be called once for each page being read as the reads
- complete. It will be called in process context if error != 0, but it may
- be called in interrupt context if there is no error.
-
-Note that a return of -ENODATA, -ENOBUFS or any other error does not preclude
-some of the pages being read and some being allocated. Those pages will have
-been marked appropriately and will need uncaching.
-
-
-Cancellation of Unread Pages
-----------------------------
-
-If one or more pages are passed to fscache_read_or_alloc_pages() but not then
-read from the cache and also not read from the underlying filesystem then
-those pages will need to have any marks and reservations removed. This can be
-done by calling::
-
- void fscache_readpages_cancel(struct fscache_cookie *cookie,
- struct list_head *pages);
-
-prior to returning to the caller. The cookie argument should be as passed to
-fscache_read_or_alloc_pages(). Every page in the pages list will be examined
-and any that have PG_fscache set will be uncached.
-
-
-Page Uncaching
-==============
-
-To uncache a page, this function should be called::
-
- void fscache_uncache_page(struct fscache_cookie *cookie,
- struct page *page);
-
-This function permits the cache to release any in-memory representation it
-might be holding for this netfs page. This function must be called once for
-each page on which the read or write page functions above have been called to
-make sure the cache's in-memory tracking information gets torn down.
-
-Note that pages can't be explicitly deleted from the a data file. The whole
-data file must be retired (see the relinquish cookie function below).
-
-Furthermore, note that this does not cancel the asynchronous read or write
-operation started by the read/alloc and write functions, so the page
-invalidation functions must use::
-
- bool fscache_check_page_write(struct fscache_cookie *cookie,
- struct page *page);
-
-to see if a page is being written to the cache, and::
-
- void fscache_wait_on_page_write(struct fscache_cookie *cookie,
- struct page *page);
-
-to wait for it to finish if it is.
-
-
-When releasepage() is being implemented, a special FS-Cache function exists to
-manage the heuristics of coping with vmscan trying to eject pages, which may
-conflict with the cache trying to write pages to the cache (which may itself
-need to allocate memory)::
-
- bool fscache_maybe_release_page(struct fscache_cookie *cookie,
- struct page *page,
- gfp_t gfp);
-
-This takes the netfs cookie, and the page and gfp arguments as supplied to
-releasepage(). It will return false if the page cannot be released yet for
-some reason and if it returns true, the page has been uncached and can now be
-released.
-
-To make a page available for release, this function may wait for an outstanding
-storage request to complete, or it may attempt to cancel the storage request -
-in which case the page will not be stored in the cache this time.
-
-
-Bulk Image Page Uncache
------------------------
-
-A convenience routine is provided to perform an uncache on all the pages
-attached to an inode. This assumes that the pages on the inode correspond on a
-1:1 basis with the pages in the cache::
-
- void fscache_uncache_all_inode_pages(struct fscache_cookie *cookie,
- struct inode *inode);
-
-This takes the netfs cookie that the pages were cached with and the inode that
-the pages are attached to. This function will wait for pages to finish being
-written to the cache and for the cache to finish with the page generally. No
-error is returned.
-
-
-Index and Data File consistency
-===============================
-
-To find out whether auxiliary data for an object is up to data within the
-cache, the following function can be called::
-
- int fscache_check_consistency(struct fscache_cookie *cookie,
- const void *aux_data);
-
-This will call back to the netfs to check whether the auxiliary data associated
-with a cookie is correct; if aux_data is non-NULL, it will update the auxiliary
-data buffer first. It returns 0 if it is and -ESTALE if it isn't; it may also
-return -ENOMEM and -ERESTARTSYS.
-
-To request an update of the index data for an index or other object, the
-following function should be called::
+To request an update of the coherency data and file size on a cookie, the
+following should be called::
void fscache_update_cookie(struct fscache_cookie *cookie,
- const void *aux_data);
-
-This function will update the cookie's auxiliary data buffer from aux_data if
-that is non-NULL and then schedule this to be stored on disk. The update
-method in the parent index definition will be called to transfer the data.
-
-Note that partial updates may happen automatically at other times, such as when
-data blocks are added to a data file object.
-
-
-Cookie Enablement
-=================
-
-Cookies exist in one of two states: enabled and disabled. If a cookie is
-disabled, it ignores all attempts to acquire child cookies; check, update or
-invalidate its state; allocate, read or write backing pages - though it is
-still possible to uncache pages and relinquish the cookie.
-
-The initial enablement state is set by fscache_acquire_cookie(), but the cookie
-can be enabled or disabled later. To disable a cookie, call::
-
- void fscache_disable_cookie(struct fscache_cookie *cookie,
- const void *aux_data,
- bool invalidate);
-
-If the cookie is not already disabled, this locks the cookie against other
-enable and disable ops, marks the cookie as being disabled, discards or
-invalidates any backing objects and waits for cessation of activity on any
-associated object before unlocking the cookie.
-
-All possible failures are handled internally. The caller should consider
-calling fscache_uncache_all_inode_pages() afterwards to make sure all page
-markings are cleared up.
-
-Cookies can be enabled or reenabled with::
-
- void fscache_enable_cookie(struct fscache_cookie *cookie,
const void *aux_data,
- loff_t object_size,
- bool (*can_enable)(void *data),
- void *data)
-
-If the cookie is not already enabled, this locks the cookie against other
-enable and disable ops, invokes can_enable() and, if the cookie is not an index
-cookie, will begin the procedure of acquiring backing objects.
-
-The optional can_enable() function is passed the data argument and returns a
-ruling as to whether or not enablement should actually be permitted to begin.
+ const loff_t *object_size);
-All possible failures are handled internally. The cookie will only be marked
-as enabled if provisional backing objects are allocated.
+This will update the cookie's coherency data and/or file size.
-The object's data size is updated from object_size and is passed to the
-->check_aux() function.
-In both cases, the cookie's auxiliary data buffer is updated from aux_data if
-that is non-NULL inside the enablement lock before proceeding.
-
-
-Miscellaneous Cookie operations
-===============================
+Data File Invalidation
+======================
-There are a number of operations that can be used to control cookies:
+Sometimes it will be necessary to invalidate an object that contains data.
+Typically this will be necessary when the server informs the network filesystem
+of a remote third-party change - at which point the filesystem has to throw
+away the state and cached data that it had for an file and reload from the
+server.
- * Cookie pinning::
+To indicate that a cache object should be invalidated, the following should be
+called::
- int fscache_pin_cookie(struct fscache_cookie *cookie);
- void fscache_unpin_cookie(struct fscache_cookie *cookie);
+ void fscache_invalidate(struct fscache_cookie *cookie,
+ const void *aux_data,
+ loff_t size,
+ unsigned int flags);
- These operations permit data cookies to be pinned into the cache and to
- have the pinning removed. They are not permitted on index cookies.
+This increases the invalidation counter in the cookie to cause outstanding
+reads to fail with -ESTALE, sets the coherency data and file size from the
+information supplied, blocks new I/O on the cookie and dispatches the cache to
+go and get rid of the old data.
- The pinning function will return 0 if successful, -ENOBUFS in the cookie
- isn't backed by a cache, -EOPNOTSUPP if the cache doesn't support pinning,
- -ENOSPC if there isn't enough space to honour the operation, -ENOMEM or
- -EIO if there's any other problem.
+Invalidation runs asynchronously in a worker thread so that it doesn't block
+too much.
- * Data space reservation::
- int fscache_reserve_space(struct fscache_cookie *cookie, loff_t size);
+Write-Back Resource Management
+==============================
- This permits a netfs to request cache space be reserved to store up to the
- given amount of a file. It is permitted to ask for more than the current
- size of the file to allow for future file expansion.
+To write data to the cache from network filesystem writeback, the cache
+resources required need to be pinned at the point the modification is made (for
+instance when the page is marked dirty) as it's not possible to open a file in
+a thread that's exiting.
- If size is given as zero then the reservation will be cancelled.
+The following facilities are provided to manage this:
- The function will return 0 if successful, -ENOBUFS in the cookie isn't
- backed by a cache, -EOPNOTSUPP if the cache doesn't support reservations,
- -ENOSPC if there isn't enough space to honour the operation, -ENOMEM or
- -EIO if there's any other problem.
+ * An inode flag, ``I_PINNING_FSCACHE_WB``, is provided to indicate that an
+ in-use is held on the cookie for this inode. It can only be changed if the
+ the inode lock is held.
- Note that this doesn't pin an object in a cache; it can still be culled to
- make space if it's not in use.
+ * A flag, ``unpinned_fscache_wb`` is placed in the ``writeback_control``
+ struct that gets set if ``__writeback_single_inode()`` clears
+ ``I_PINNING_FSCACHE_WB`` because all the dirty pages were cleared.
+To support this, the following functions are provided::
-Cookie Unregistration
-=====================
+ int fscache_set_page_dirty(struct page *page,
+ struct fscache_cookie *cookie);
+ void fscache_unpin_writeback(struct writeback_control *wbc,
+ struct fscache_cookie *cookie);
+ void fscache_clear_inode_writeback(struct fscache_cookie *cookie,
+ struct inode *inode,
+ const void *aux);
-To get rid of a cookie, this function should be called::
+The *set* function is intended to be called from the filesystem's
+``set_page_dirty`` address space operation. If ``I_PINNING_FSCACHE_WB`` is not
+set, it sets that flag and increments the use count on the cookie (the caller
+must already have called ``fscache_use_cookie()``).
- void fscache_relinquish_cookie(struct fscache_cookie *cookie,
- const void *aux_data,
- bool retire);
+The *unpin* function is intended to be called from the filesystem's
+``write_inode`` superblock operation. It cleans up after writing by unusing
+the cookie if unpinned_fscache_wb is set in the writeback_control struct.
-If retire is non-zero, then the object will be marked for recycling, and all
-copies of it will be removed from all active caches in which it is present.
-Not only that but all child objects will also be retired.
+The *clear* function is intended to be called from the netfs's ``evict_inode``
+superblock operation. It must be called *after*
+``truncate_inode_pages_final()``, but *before* ``clear_inode()``. This cleans
+up any hanging ``I_PINNING_FSCACHE_WB``. It also allows the coherency data to
+be updated.
-If retire is zero, then the object may be available again when next the
-acquisition function is called. Retirement here will overrule the pinning on a
-cookie.
-The cookie's auxiliary data will be updated from aux_data if that is non-NULL
-so that the cache can lazily update it on disk.
+Caching of Local Modifications
+==============================
-One very important note - relinquish must NOT be called for a cookie unless all
-the cookies for "child" indices, objects and pages have been relinquished
-first.
+If a network filesystem has locally modified data that it wants to write to the
+cache, it needs to mark the pages to indicate that a write is in progress, and
+if the mark is already present, it needs to wait for it to be removed first
+(presumably due to an already in-progress operation). This prevents multiple
+competing DIO writes to the same storage in the cache.
+Firstly, the netfs should determine if caching is available by doing something
+like::
-Index Invalidation
-==================
+ bool caching = fscache_cookie_enabled(cookie);
-There is no direct way to invalidate an index subtree. To do this, the caller
-should relinquish and retire the cookie they have, and then acquire a new one.
+If caching is to be attempted, pages should be waited for and then marked using
+the following functions provided by the netfs helper library::
+ void set_page_fscache(struct page *page);
+ void wait_on_page_fscache(struct page *page);
+ int wait_on_page_fscache_killable(struct page *page);
-Data File Invalidation
-======================
+Once all the pages in the span are marked, the netfs can ask fscache to
+schedule a write of that region::
-Sometimes it will be necessary to invalidate an object that contains data.
-Typically this will be necessary when the server tells the netfs of a foreign
-change - at which point the netfs has to throw away all the state it had for an
-inode and reload from the server.
+ void fscache_write_to_cache(struct fscache_cookie *cookie,
+ struct address_space *mapping,
+ loff_t start, size_t len, loff_t i_size,
+ netfs_io_terminated_t term_func,
+ void *term_func_priv,
+ bool caching)
-To indicate that a cache object should be invalidated, the following function
-can be called::
+And if an error occurs before that point is reached, the marks can be removed
+by calling::
- void fscache_invalidate(struct fscache_cookie *cookie);
+ void fscache_clear_page_bits(struct fscache_cookie *cookie,
+ struct address_space *mapping,
+ loff_t start, size_t len,
+ bool caching)
-This can be called with spinlocks held as it defers the work to a thread pool.
-All extant storage, retrieval and attribute change ops at this point are
-cancelled and discarded. Some future operations will be rejected until the
-cache has had a chance to insert a barrier in the operations queue. After
-that, operations will be queued again behind the invalidation operation.
+In both of these functions, the cookie representing the cache object to be
+written to and a pointer to the mapping to which the source pages are attached
+are passed in; start and len indicate the size of the region that's going to be
+written (it doesn't have to align to page boundaries necessarily, but it does
+have to align to DIO boundaries on the backing filesystem). The caching
+parameter indicates if caching should be skipped, and if false, the functions
+do nothing.
-The invalidation operation will perform an attribute change operation and an
-auxiliary data update operation as it is very likely these will have changed.
+The write function takes some additional parameters: i_size indicates the size
+of the netfs file and term_func indicates an optional completion function, to
+which term_func_priv will be passed, along with the error or amount written.
-Using the following function, the netfs can wait for the invalidation operation
-to have reached a point at which it can start submitting ordinary operations
-once again::
+Note that the write function will always run asynchronously and will unmark all
+the pages upon completion before calling term_func.
- void fscache_wait_on_invalidate(struct fscache_cookie *cookie);
+Page Release and Invalidation
+=============================
-FS-cache Specific Page Flag
-===========================
+Fscache keeps track of whether we have any data in the cache yet for a cache
+object we've just created. It knows it doesn't have to do any reading until it
+has done a write and then the page it wrote from has been released by the VM,
+after which it *has* to look in the cache.
-FS-Cache makes use of a page flag, PG_private_2, for its own purpose. This is
-given the alternative name PG_fscache.
+To inform fscache that a page might now be in the cache, the following function
+should be called from the ``releasepage`` address space op::
-PG_fscache is used to indicate that the page is known by the cache, and that
-the cache must be informed if the page is going to go away. It's an indication
-to the netfs that the cache has an interest in this page, where an interest may
-be a pointer to it, resources allocated or reserved for it, or I/O in progress
-upon it.
+ void fscache_note_page_release(struct fscache_cookie *cookie);
-The netfs can use this information in methods such as releasepage() to
-determine whether it needs to uncache a page or update it.
+if the page has been released (ie. releasepage returned true).
-Furthermore, if this bit is set, releasepage() and invalidatepage() operations
-will be called on a page to get rid of it, even if PG_private is not set. This
-allows caching to attempted on a page before read_cache_pages() to be called
-after fscache_read_or_alloc_pages() as the former will try and release pages it
-was given under certain circumstances.
+Page release and page invalidation should also wait for any mark left on the
+page to say that a DIO write is underway from that page::
-This bit does not overlap with such as PG_private. This means that FS-Cache
-can be used with a filesystem that uses the block buffering code.
+ void wait_on_page_fscache(struct page *page);
+ int wait_on_page_fscache_killable(struct page *page);
-There are a number of operations defined on this flag::
- int PageFsCache(struct page *page);
- void SetPageFsCache(struct page *page)
- void ClearPageFsCache(struct page *page)
- int TestSetPageFsCache(struct page *page)
- int TestClearPageFsCache(struct page *page)
+API Function Reference
+======================
-These functions are bit test, bit set, bit clear, bit test and set and bit
-test and clear operations on PG_fscache.

-Representation
-==============
-
-FS-Cache maintains an in-kernel representation of each object that a netfs is
-currently interested in. Such objects are represented by the fscache_cookie
-struct and are referred to as cookies.
-
-FS-Cache also maintains a separate in-kernel representation of the objects that
-a cache backend is currently actively caching. Such objects are represented by
-the fscache_object struct. The cache backends allocate these upon request, and
-are expected to embed them in their own representations. These are referred to
-as objects.
-
-There is a 1:N relationship between cookies and objects. A cookie may be
-represented by multiple objects - an index may exist in more than one cache -
-or even by no objects (it may not be cached).
-
-Furthermore, both cookies and objects are hierarchical. The two hierarchies
-correspond, but the cookies tree is a superset of the union of the object trees
-of multiple caches::

-In the above illustration, ICookie and IObject represent indices and DCookie
-and DObject represent data storage objects. Indices may have representation in
-multiple caches, but currently, non-index objects may not. Objects of any type
-may also be entirely unrepresented.
-
-As far as the netfs API goes, the netfs is only actually permitted to see
-pointers to the cookies. The cookies themselves and any objects attached to
-those cookies are hidden from it.
-
-
-Object Management State Machine
-===============================
-
-Within FS-Cache, each active object is managed by its own individual state
-machine. The state for an object is kept in the fscache_object struct, in
-object->state. A cookie may point to a set of objects that are in different
-states.
-
-Each state has an action associated with it that is invoked when the machine
-wakes up in that state. There are four logical sets of states:
-
- (1) Preparation: states that wait for the parent objects to become ready. The
- representations are hierarchical, and it is expected that an object must
- be created or accessed with respect to its parent object.
-
- (2) Initialisation: states that perform lookups in the cache and validate
- what's found and that create on disk any missing metadata.
-
- (3) Normal running: states that allow netfs operations on objects to proceed
- and that update the state of objects.
-
- (4) Termination: states that detach objects from their netfs cookies, that
- delete objects from disk, that handle disk and system errors and that free
- up in-memory resources.
-
-
-In most cases, transitioning between states is in response to signalled events.
-When a state has finished processing, it will usually set the mask of events in
-which it is interested (object->event_mask) and relinquish the worker thread.
-Then when an event is raised (by calling fscache_raise_event()), if the event
-is not masked, the object will be queued for processing (by calling
-fscache_enqueue_object()).
-
-
-Provision of CPU Time
----------------------
-
-The work to be done by the various states was given CPU time by the threads of
-the slow work facility. This was used in preference to the workqueue facility
-because:
-
- (1) Threads may be completely occupied for very long periods of time by a
- particular work item. These state actions may be doing sequences of
- synchronous, journalled disk accesses (lookup, mkdir, create, setxattr,
- getxattr, truncate, unlink, rmdir, rename).
-
- (2) Threads may do little actual work, but may rather spend a lot of time
- sleeping on I/O. This means that single-threaded and 1-per-CPU-threaded
- workqueues don't necessarily have the right numbers of threads.
-
-
-Locking Simplification
-----------------------
-
-Because only one worker thread may be operating on any particular object's
-state machine at once, this simplifies the locking, particularly with respect
-to disconnecting the netfs's representation of a cache object (fscache_cookie)
-from the cache backend's representation (fscache_object) - which may be
-requested from either end.
-
-
-The Set of States
-=================
-
-The object state machine has a set of states that it can be in. There are
-preparation states in which the object sets itself up and waits for its parent
-object to transit to a state that allows access to its children:
-
- (1) State FSCACHE_OBJECT_INIT.
-
- Initialise the object and wait for the parent object to become active. In
- the cache, it is expected that it will not be possible to look an object
- up from the parent object, until that parent object itself has been looked
- up.
-
-There are initialisation states in which the object sets itself up and accesses
-disk for the object metadata:
-
- (2) State FSCACHE_OBJECT_LOOKING_UP.
-
- Look up the object on disk, using the parent as a starting point.
- FS-Cache expects the cache backend to probe the cache to see whether this
- object is represented there, and if it is, to see if it's valid (coherency
- management).
-
- The cache should call fscache_object_lookup_negative() to indicate lookup
- failure for whatever reason, and should call fscache_obtained_object() to
- indicate success.
-
- At the completion of lookup, FS-Cache will let the netfs go ahead with
- read operations, no matter whether the file is yet cached. If not yet
- cached, read operations will be immediately rejected with ENODATA until
- the first known page is uncached - as to that point there can be no data
- to be read out of the cache for that file that isn't currently also held
- in the pagecache.
-
- (3) State FSCACHE_OBJECT_CREATING.
-
- Create an object on disk, using the parent as a starting point. This
- happens if the lookup failed to find the object, or if the object's
- coherency data indicated what's on disk is out of date. In this state,
- FS-Cache expects the cache to create
-
- The cache should call fscache_obtained_object() if creation completes
- successfully, fscache_object_lookup_negative() otherwise.
-
- At the completion of creation, FS-Cache will start processing write
- operations the netfs has queued for an object. If creation failed, the
- write ops will be transparently discarded, and nothing recorded in the
- cache.
-
-There are some normal running states in which the object spends its time
-servicing netfs requests:
-
- (4) State FSCACHE_OBJECT_AVAILABLE.
-
- A transient state in which pending operations are started, child objects
- are permitted to advance from FSCACHE_OBJECT_INIT state, and temporary
- lookup data is freed.
-
- (5) State FSCACHE_OBJECT_ACTIVE.
-
- The normal running state. In this state, requests the netfs makes will be
- passed on to the cache.
-
- (6) State FSCACHE_OBJECT_INVALIDATING.
-
- The object is undergoing invalidation. When the state comes here, it
- discards all pending read, write and attribute change operations as it is
- going to clear out the cache entirely and reinitialise it. It will then
- continue to the FSCACHE_OBJECT_UPDATING state.
-
- (7) State FSCACHE_OBJECT_UPDATING.
-
- The state machine comes here to update the object in the cache from the
- netfs's records. This involves updating the auxiliary data that is used
- to maintain coherency.
-
-And there are terminal states in which an object cleans itself up, deallocates
-memory and potentially deletes stuff from disk:
-
- (8) State FSCACHE_OBJECT_LC_DYING.
-
- The object comes here if it is dying because of a lookup or creation
- error. This would be due to a disk error or system error of some sort.
- Temporary data is cleaned up, and the parent is released.
-
- (9) State FSCACHE_OBJECT_DYING.
-
- The object comes here if it is dying due to an error, because its parent
- cookie has been relinquished by the netfs or because the cache is being
- withdrawn.
-
- Any child objects waiting on this one are given CPU time so that they too
- can destroy themselves. This object waits for all its children to go away
- before advancing to the next state.
-
-(10) State FSCACHE_OBJECT_ABORT_INIT.
-
- The object comes to this state if it was waiting on its parent in
- FSCACHE_OBJECT_INIT, but its parent died. The object will destroy itself
- so that the parent may proceed from the FSCACHE_OBJECT_DYING state.
-
-(11) State FSCACHE_OBJECT_RELEASING.
-(12) State FSCACHE_OBJECT_RECYCLING.
-
- The object comes to one of these two states when dying once it is rid of
- all its children, if it is dying because the netfs relinquished its
- cookie. In the first state, the cached data is expected to persist, and
- in the second it will be deleted.
-
-(13) State FSCACHE_OBJECT_WITHDRAWING.
-
- The object transits to this state if the cache decides it wants to
- withdraw the object from service, perhaps to make space, but also due to
- error or just because the whole cache is being withdrawn.
-
-(14) State FSCACHE_OBJECT_DEAD.
-
- The object transits to this state when the in-memory object record is
- ready to be deleted. The object processor shouldn't ever see an object in
- this state.
-
-
-The Set of Events
------------------
-
-There are a number of events that can be raised to an object state machine:
-
- FSCACHE_OBJECT_EV_UPDATE
- The netfs requested that an object be updated. The state machine will ask
- the cache backend to update the object, and the cache backend will ask the
- netfs for details of the change through its cookie definition ops.
-
- FSCACHE_OBJECT_EV_CLEARED
- This is signalled in two circumstances:
-
- (a) when an object's last child object is dropped and
-
- (b) when the last operation outstanding on an object is completed.
-
- This is used to proceed from the dying state.
-
- FSCACHE_OBJECT_EV_ERROR
- This is signalled when an I/O error occurs during the processing of some
- object.
-
- FSCACHE_OBJECT_EV_RELEASE, FSCACHE_OBJECT_EV_RETIRE
- These are signalled when the netfs relinquishes a cookie it was using.
- The event selected depends on whether the netfs asks for the backing
- object to be retired (deleted) or retained.
-
- FSCACHE_OBJECT_EV_WITHDRAW
- This is signalled when the cache backend wants to withdraw an object.
- This means that the object will have to be detached from the netfs's
- cookie.
-
-Because the withdrawing releasing/retiring events are all handled by the object
-state machine, it doesn't matter if there's a collision with both ends trying
-to sever the connection at the same time. The state machine can just pick
-which one it wants to honour, and that effects the other.

-Asynchronous Operations Handling

-
-Overview
-========
-
-FS-Cache has an asynchronous operations handling facility that it uses for its
-data storage and retrieval routines. Its operations are represented by
-fscache_operation structs, though these are usually embedded into some other
-structure.
-
-This facility is available to and expected to be used by the cache backends,
-and FS-Cache will create operations and pass them off to the appropriate cache
-backend for completion.
-
-To make use of this facility, <linux/fscache-cache.h> should be #included.
-
-
-Operation Record Initialisation
-===============================
-
-An operation is recorded in an fscache_operation struct::
-
- struct fscache_operation {
- union {
- struct work_struct fast_work;
- struct slow_work slow_work;
- };
- unsigned long flags;
- fscache_operation_processor_t processor;
- ...
- };
-
-Someone wanting to issue an operation should allocate something with this
-struct embedded in it. They should initialise it by calling::
-
- void fscache_operation_init(struct fscache_operation *op,
- fscache_operation_release_t release);
-
-with the operation to be initialised and the release function to use.
-
-The op->flags parameter should be set to indicate the CPU time provision and
-the exclusivity (see the Parameters section).
-
-The op->fast_work, op->slow_work and op->processor flags should be set as
-appropriate for the CPU time provision (see the Parameters section).
-
-FSCACHE_OP_WAITING may be set in op->flags prior to each submission of the
-operation and waited for afterwards.
-
-
-Parameters
-==========
-
-There are a number of parameters that can be set in the operation record's flag
-parameter. There are three options for the provision of CPU time in these
-operations:
-
- (1) The operation may be done synchronously (FSCACHE_OP_MYTHREAD). A thread
- may decide it wants to handle an operation itself without deferring it to
- another thread.
-
- This is, for example, used in read operations for calling readpages() on
- the backing filesystem in CacheFiles. Although readpages() does an
- asynchronous data fetch, the determination of whether pages exist is done
- synchronously - and the netfs does not proceed until this has been
- determined.
-
- If this option is to be used, FSCACHE_OP_WAITING must be set in op->flags
- before submitting the operation, and the operating thread must wait for it
- to be cleared before proceeding::
-
- wait_on_bit(&op->flags, FSCACHE_OP_WAITING,
- TASK_UNINTERRUPTIBLE);
-
-
- (2) The operation may be fast asynchronous (FSCACHE_OP_FAST), in which case it
- will be given to keventd to process. Such an operation is not permitted
- to sleep on I/O.
-
- This is, for example, used by CacheFiles to copy data from a backing fs
- page to a netfs page after the backing fs has read the page in.
-
- If this option is used, op->fast_work and op->processor must be
- initialised before submitting the operation::
-
- INIT_WORK(&op->fast_work, do_some_work);
-
-
- (3) The operation may be slow asynchronous (FSCACHE_OP_SLOW), in which case it
- will be given to the slow work facility to process. Such an operation is
- permitted to sleep on I/O.
-
- This is, for example, used by FS-Cache to handle background writes of
- pages that have just been fetched from a remote server.
-
- If this option is used, op->slow_work and op->processor must be
- initialised before submitting the operation::
-
- fscache_operation_init_slow(op, processor)
-
-
-Furthermore, operations may be one of two types:
-
- (1) Exclusive (FSCACHE_OP_EXCLUSIVE). Operations of this type may not run in
- conjunction with any other operation on the object being operated upon.
-
- An example of this is the attribute change operation, in which the file
- being written to may need truncation.
-
- (2) Shareable. Operations of this type may be running simultaneously. It's
- up to the operation implementation to prevent interference between other
- operations running at the same time.
-
-
-Procedure
-=========
-
-Operations are used through the following procedure:
-
- (1) The submitting thread must allocate the operation and initialise it
- itself. Normally this would be part of a more specific structure with the
- generic op embedded within.
-
- (2) The submitting thread must then submit the operation for processing using
- one of the following two functions::
-
- int fscache_submit_op(struct fscache_object *object,
- struct fscache_operation *op);
-
- int fscache_submit_exclusive_op(struct fscache_object *object,
- struct fscache_operation *op);
-
- The first function should be used to submit non-exclusive ops and the
- second to submit exclusive ones. The caller must still set the
- FSCACHE_OP_EXCLUSIVE flag.
-
- If successful, both functions will assign the operation to the specified
- object and return 0. -ENOBUFS will be returned if the object specified is
- permanently unavailable.
-
- The operation manager will defer operations on an object that is still
- undergoing lookup or creation. The operation will also be deferred if an
- operation of conflicting exclusivity is in progress on the object.
-
- If the operation is asynchronous, the manager will retain a reference to
- it, so the caller should put their reference to it by passing it to::
-
- void fscache_put_operation(struct fscache_operation *op);
-
- (3) If the submitting thread wants to do the work itself, and has marked the
- operation with FSCACHE_OP_MYTHREAD, then it should monitor
- FSCACHE_OP_WAITING as described above and check the state of the object if
- necessary (the object might have died while the thread was waiting).
-
- When it has finished doing its processing, it should call
- fscache_op_complete() and fscache_put_operation() on it.
-
- (4) The operation holds an effective lock upon the object, preventing other
- exclusive ops conflicting until it is released. The operation can be
- enqueued for further immediate asynchronous processing by adjusting the
- CPU time provisioning option if necessary, eg::
-
- op->flags &= ~FSCACHE_OP_TYPE;
- op->flags |= ~FSCACHE_OP_FAST;
-
- and calling::
-
- void fscache_enqueue_operation(struct fscache_operation *op)
-
- This can be used to allow other things to have use of the worker thread
- pools.
-
-
-Asynchronous Callback
-=====================
-
-When used in asynchronous mode, the worker thread pool will invoke the
-processor method with a pointer to the operation. This should then get at the
-container struct by using container_of()::
-
- static void fscache_write_op(struct fscache_operation *_op)
- {
- struct fscache_storage *op =
- container_of(_op, struct fscache_storage, op);
- ...
- }
-
-The caller holds a reference on the operation, and will invoke
-fscache_put_operation() when the processor function returns. The processor
-function is at liberty to call fscache_enqueue_operation() or to take extra
-references.

-Shortcircuting
---------------
-
-Currently, the implementation of idmapped mounts enforces that the filesystem
-is mounted with the initial idmapping. The reason is simply that none of the
-filesystems that we targeted were mountable with a non-initial idmapping. But
-that might change soon enough. As we've seen above, thanks to the properties of
-idmappings the translation works for both filesystems mounted with the initial
-idmapping and filesystem with non-initial idmappings.
-
-Based on this current restriction to filesystem mounted with the initial
-idmapping two noticeable shortcuts have been taken:
-
-1. We always stash a reference to the initial user namespace in ``struct
- vfsmount``. Idmapped mounts are thus mounts that have a non-initial user
- namespace attached to them.
-
- In order to support idmapped mounts this needs to be changed. Instead of
- stashing the initial user namespace the user namespace the filesystem was
- mounted with must be stashed. An idmapped mount is then any mount that has
- a different user namespace attached then the filesystem was mounted with.
- This has no user-visible consequences.
-
-2. The translation algorithms in ``mapped_fs*id()`` and ``i_*id_into_mnt()``
- are simplified.
-
- Let's consider ``mapped_fs*id()`` first. This function translates the
- caller's kernel id into a kernel id in the filesystem's idmapping via
- a mount's idmapping. The full algorithm is::
-
- mapped_fsuid(kid):
- /* Map the kernel id up into a userspace id in the mount's idmapping. */
- from_kuid(mount-idmapping, kid) = uid
-
- /* Map the userspace id down into a kernel id in the filesystem's idmapping. */
- make_kuid(filesystem-idmapping, uid) = kuid
-
- We know that the filesystem is always mounted with the initial idmapping as
- we enforce this in ``mount_setattr()``. So this can be shortened to::
-
- mapped_fsuid(kid):
- /* Map the kernel id up into a userspace id in the mount's idmapping. */
- from_kuid(mount-idmapping, kid) = uid
-
- /* Map the userspace id down into a kernel id in the filesystem's idmapping. */
- KUIDT_INIT(uid) = kuid
-
- Similarly, for ``i_*id_into_mnt()`` which translated the filesystem's kernel
- id into a mount's kernel id::
-
- i_uid_into_mnt(kid):
- /* Map the kernel id up into a userspace id in the filesystem's idmapping. */
- from_kuid(filesystem-idmapping, kid) = uid
-
- /* Map the userspace id down into a kernel id in the mounts's idmapping. */
- make_kuid(mount-idmapping, uid) = kuid
-
- Again, we know that the filesystem is always mounted with the initial
- idmapping as we enforce this in ``mount_setattr()``. So this can be
- shortened to::
-
- i_uid_into_mnt(kid):
- /* Map the kernel id up into a userspace id in the filesystem's idmapping. */
- __kuid_val(kid) = uid
-
- /* Map the userspace id down into a kernel id in the mounts's idmapping. */
- make_kuid(mount-idmapping, uid) = kuid
-
-Handling filesystems mounted with non-initial idmappings requires that the
-translation functions be converted to their full form. They can still be
-shortcircuited on non-idmapped mounts. This has no user-visible consequences.

-Because it is partially shared with other operating systems, the Display Core
-Driver is divided in two pieces.
-
-1. **Display Core (DC)** contains the OS-agnostic components. Things like
- hardware programming and resource management are handled here.
-2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
- amdgpu base driver and DRM are implemented here.
-
-It doesn't help that the entire package is frequently referred to as DC. But
-with the context in mind, it should be clear.
-
-When CONFIG_DRM_AMD_DC is enabled, DC will be initialized by default for
-supported ASICs. To force disable, set `amdgpu.dc=0` on kernel command line.
-Likewise, to force enable on unsupported ASICs, set `amdgpu.dc=1`.

+========================
+Display Core Debug tools
+========================
+
+DC Visual Confirmation
+======================
+
+Display core provides a feature named visual confirmation, which is a set of
+bars added at the scanout time by the driver to convey some specific
+information. In general, you can enable this debug option by using::
+
+ echo <N> > /sys/kernel/debug/dri/0/amdgpu_dm_visual_confirm
+
+Where `N` is an integer number for some specific scenarios that the developer
+wants to enable, you will see some of these debug cases in the following
+subsection.
+
+Multiple Planes Debug
+---------------------
+
+If you want to enable or debug multiple planes in a specific user-space
+application, you can leverage a debug feature named visual confirm. For
+enabling it, you will need::
+
+ echo 1 > /sys/kernel/debug/dri/0/amdgpu_dm_visual_confirm
+
+You need to reload your GUI to see the visual confirmation. When the plane
+configuration changes or a full update occurs there will be a colored bar at
+the bottom of each hardware plane being drawn on the screen.
+
+* The color indicates the format - For example, red is AR24 and green is NV12
+* The height of the bar indicates the index of the plane
+* Pipe split can be observed if there are two bars with a difference in height
+ covering the same plane
+
+Consider the video playback case in which a video is played in a specific
+plane, and the desktop is drawn in another plane. The video plane should
+feature one or two green bars at the bottom of the video depending on pipe
+split configuration.
+
+* There should **not** be any visual corruption
+* There should **not** be any underflow or screen flashes
+* There should **not** be any black screens
+* There should **not** be any cursor corruption
+* Multiple plane **may** be briefly disabled during window transitions or
+ resizing but should come back after the action has finished
+
+Pipe Split Debug
+----------------
+
+Sometimes we need to debug if DCN is splitting pipes correctly, and visual
+confirmation is also handy for this case. Similar to the MPO case, you can use
+the below command to enable visual confirmation::
+
+ echo 1 > /sys/kernel/debug/dri/0/amdgpu_dm_visual_confirm
+
+In this case, if you have a pipe split, you will see one small red bar at the
+bottom of the display covering the entire display width and another bar
+covering the second pipe. In other words, you will see a bit high bar in the
+second pipe.
+
+DTN Debug
+=========
+
+DC (DCN) provides an extensive log that dumps multiple details from our
+hardware configuration. Via debugfs, you can capture those status values by
+using Display Test Next (DTN) log, which can be captured via debugfs by using::
+
+ cat /sys/kernel/debug/dri/0/amdgpu_dm_dtn_log
+
+Since this log is updated accordingly with DCN status, you can also follow the
+change in real-time by using something like::
+
+ sudo watch -d cat /sys/kernel/debug/dri/0/amdgpu_dm_dtn_log
+
+When reporting a bug related to DC, consider attaching this log before and
+after you reproduce the bug.

+=======================
+Display Core Next (DCN)
+=======================
+
+To equip our readers with the basic knowledge of how AMD Display Core Next
+(DCN) works, we need to start with an overview of the hardware pipeline. Below
+you can see a picture that provides a DCN overview, keep in mind that this is a
+generic diagram, and we have variations per ASIC.
+
+.. kernel-figure:: dc_pipeline_overview.svg
+
+Based on this diagram, we can pass through each block and briefly describe
+them:
+
+* **Display Controller Hub (DCHUB)**: This is the gateway between the Scalable
+ Data Port (SDP) and DCN. This component has multiple features, such as memory
+ arbitration, rotation, and cursor manipulation.
+
+* **Display Pipe and Plane (DPP)**: This block provides pre-blend pixel
+ processing such as color space conversion, linearization of pixel data, tone
+ mapping, and gamut mapping.
+
+* **Multiple Pipe/Plane Combined (MPC)**: This component performs blending of
+ multiple planes, using global or per-pixel alpha.
+
+* **Output Pixel Processing (OPP)**: Process and format pixels to be sent to
+ the display.
+
+* **Output Pipe Timing Combiner (OPTC)**: It generates time output to combine
+ streams or divide capabilities. CRC values are generated in this block.
+
+* **Display Output (DIO)**: Codify the output to the display connected to our
+ GPU.
+
+* **Display Writeback (DWB)**: It provides the ability to write the output of
+ the display pipe back to memory as video frames.
+
+* **Multi-Media HUB (MMHUBBUB)**: Memory controller interface for DMCUB and DWB
+ (Note that DWB is not hooked yet).
+
+* **DCN Management Unit (DMU)**: It provides registers with access control and
+ interrupts the controller to the SOC host interrupt unit. This block includes
+ the Display Micro-Controller Unit - version B (DMCUB), which is handled via
+ firmware.
+
+* **DCN Clock Generator Block (DCCG)**: It provides the clocks and resets
+ for all of the display controller clock domains.
+
+* **Azalia (AZ)**: Audio engine.
+
+The above diagram is an architecture generalization of DCN, which means that
+every ASIC has variations around this base model. Notice that the display
+pipeline is connected to the Scalable Data Port (SDP) via DCHUB; you can see
+the SDP as the element from our Data Fabric that feeds the display pipe.
+
+Always approach the DCN architecture as something flexible that can be
+configured and reconfigured in multiple ways; in other words, each block can be
+setup or ignored accordingly with userspace demands. For example, if we
+want to drive an 8k@60Hz with a DSC enabled, our DCN may require 4 DPP and 2
+OPP. It is DC's responsibility to drive the best configuration for each
+specific scenario. Orchestrate all of these components together requires a
+sophisticated communication interface which is highlighted in the diagram by
+the edges that connect each block; from the chart, each connection between
+these blocks represents:
+
+1. Pixel data interface (red): Represents the pixel data flow;
+2. Global sync signals (green): It is a set of synchronization signals composed
+ by VStartup, VUpdate, and VReady;
+3. Config interface: Responsible to configure blocks;
+4. Sideband signals: All other signals that do not fit the previous one.
+
+These signals are essential and play an important role in DCN. Nevertheless,
+the Global Sync deserves an extra level of detail described in the next
+section.
+
+All of these components are represented by a data structure named dc_state.
+From DCHUB to MPC, we have a representation called dc_plane; from MPC to OPTC,
+we have dc_stream, and the output (DIO) is handled by dc_link. Keep in mind
+that HUBP accesses a surface using a specific format read from memory, and our
+dc_plane should work to convert all pixels in the plane to something that can
+be sent to the display via dc_stream and dc_link.
+
+Front End and Back End
+----------------------
+
+Display pipeline can be broken down into two components that are usually
+referred as **Front End (FE)** and **Back End (BE)**, where FE consists of:
+
+* DCHUB (Mainly referring to a subcomponent named HUBP)
+* DPP
+* MPC
+
+On the other hand, BE consist of
+
+* OPP
+* OPTC
+* DIO (DP/HDMI stream encoder and link encoder)
+
+OPP and OPTC are two joining blocks between FE and BE. On a side note, this is
+a one-to-one mapping of the link encoder to PHY, but we can configure the DCN
+to choose which link encoder to connect to which PHY. FE's main responsibility
+is to change, blend and compose pixel data, while BE's job is to frame a
+generic pixel stream to a specific display's pixel stream.
+
+Data Flow
+---------
+
+Initially, data is passed in from VRAM through Data Fabric (DF) in native pixel
+formats. Such data format stays through till HUBP in DCHUB, where HUBP unpacks
+different pixel formats and outputs them to DPP in uniform streams through 4
+channels (1 for alpha + 3 for colors).
+
+The Converter and Cursor (CNVC) in DPP would then normalize the data
+representation and convert them to a DCN specific floating-point format (i.e.,
+different from the IEEE floating-point format). In the process, CNVC also
+applies a degamma function to transform the data from non-linear to linear
+space to relax the floating-point calculations following. Data would stay in
+this floating-point format from DPP to OPP.
+
+Starting OPP, because color transformation and blending have been completed
+(i.e alpha can be dropped), and the end sinks do not require the precision and
+dynamic range that floating points provide (i.e. all displays are in integer
+depth format), bit-depth reduction/dithering would kick in. In OPP, we would
+also apply a regamma function to introduce the gamma removed earlier back.
+Eventually, we output data in integer format at DIO.
+
+Global Sync
+-----------
+
+Many DCN registers are double buffered, most importantly the surface address.
+This allows us to update DCN hardware atomically for page flips, as well as
+for most other updates that don't require enabling or disabling of new pipes.
+
+(Note: There are many scenarios when DC will decide to reserve extra pipes
+in order to support outputs that need a very high pixel clock, or for
+power saving purposes.)
+
+These atomic register updates are driven by global sync signals in DCN. In
+order to understand how atomic updates interact with DCN hardware, and how DCN
+signals page flip and vblank events it is helpful to understand how global sync
+is programmed.
+
+Global sync consists of three signals, VSTARTUP, VUPDATE, and VREADY. These are
+calculated by the Display Mode Library - DML (drivers/gpu/drm/amd/display/dc/dml)
+based on a large number of parameters and ensure our hardware is able to feed
+the DCN pipeline without underflows or hangs in any given system configuration.
+The global sync signals always happen during VBlank, are independent from the
+VSync signal, and do not overlap each other.
+
+VUPDATE is the only signal that is of interest to the rest of the driver stack
+or userspace clients as it signals the point at which hardware latches to
+atomically programmed (i.e. double buffered) registers. Even though it is
+independent of the VSync signal we use VUPDATE to signal the VSync event as it
+provides the best indication of how atomic commits and hardware interact.
+
+Since DCN hardware is double-buffered the DC driver is able to program the
+hardware at any point during the frame.
+
+The below picture illustrates the global sync signals:
+
+.. kernel-figure:: global_sync_vblank.svg
+
+These signals affect core DCN behavior. Programming them incorrectly will lead
+to a number of negative consequences, most of them quite catastrophic.
+
+The following picture shows how global sync allows for a mailbox style of
+updates, i.e. it allows for multiple re-configurations between VUpdate
+events where only the last configuration programmed before the VUpdate signal
+becomes effective.

+drm/amd/display - Display Core (DC)
+===================================
+
+AMD display engine is partially shared with other operating systems; for this
+reason, our Display Core Driver is divided into two pieces:
+
+1. **Display Core (DC)** contains the OS-agnostic components. Things like
+ hardware programming and resource management are handled here.
+2. **Display Manager (DM)** contains the OS-dependent components. Hooks to the
+ amdgpu base driver and DRM are implemented here.
+
+The display pipe is responsible for "scanning out" a rendered frame from the
+GPU memory (also called VRAM, FrameBuffer, etc.) to a display. In other words,
+it would:
+
+1. Read frame information from memory;
+2. Perform required transformation;
+3. Send pixel data to sink devices.
+
+If you want to learn more about our driver details, take a look at the below
+table of content:

+============================
+ Core Driver Infrastructure
+============================
+
+GPU Hardware Structure
+======================
+
+Each ASIC is a collection of hardware blocks. We refer to them as
+"IPs" (Intellectual Property blocks). Each IP encapsulates certain
+functionality. IPs are versioned and can also be mixed and matched.
+E.g., you might have two different ASICs that both have System DMA (SDMA) 5.x IPs.
+The driver is arranged by IPs. There are driver components to handle
+the initialization and operation of each IP. There are also a bunch
+of smaller IPs that don't really need much if any driver interaction.
+Those end up getting lumped into the common stuff in the soc files.
+The soc files (e.g., vi.c, soc15.c nv.c) contain code for aspects of
+the SoC itself rather than specific IPs. E.g., things like GPU resets
+and register access functions are SoC dependent.
+
+An APU contains more than just CPU and GPU, it also contains all of
+the platform stuff (audio, usb, gpio, etc.). Also, a lot of
+components are shared between the CPU, platform, and the GPU (e.g.,
+SMU, PSP, etc.). Specific components (CPU, GPU, etc.) usually have
+their interface to interact with those common components. For things
+like S0i3 there is a ton of coordination required across all the
+components, but that is probably a bit beyond the scope of this
+section.
+
+With respect to the GPU, we have the following major IPs:
+
+GMC (Graphics Memory Controller)
+ This was a dedicated IP on older pre-vega chips, but has since
+ become somewhat decentralized on vega and newer chips. They now
+ have dedicated memory hubs for specific IPs or groups of IPs. We
+ still treat it as a single component in the driver however since
+ the programming model is still pretty similar. This is how the
+ different IPs on the GPU get the memory (VRAM or system memory).
+ It also provides the support for per process GPU virtual address
+ spaces.
+
+IH (Interrupt Handler)
+ This is the interrupt controller on the GPU. All of the IPs feed
+ their interrupts into this IP and it aggregates them into a set of
+ ring buffers that the driver can parse to handle interrupts from
+ different IPs.
+
+PSP (Platform Security Processor)
+ This handles security policy for the SoC and executes trusted
+ applications, and validates and loads firmwares for other blocks.
+
+SMU (System Management Unit)
+ This is the power management microcontroller. It manages the entire
+ SoC. The driver interacts with it to control power management
+ features like clocks, voltages, power rails, etc.
+
+DCN (Display Controller Next)
+ This is the display controller. It handles the display hardware.
+ It is described in more details in :ref:`Display Core <amdgpu-display-core>`.
+
+SDMA (System DMA)
+ This is a multi-purpose DMA engine. The kernel driver uses it for
+ various things including paging and GPU page table updates. It's also
+ exposed to userspace for use by user mode drivers (OpenGL, Vulkan,
+ etc.)
+
+GC (Graphics and Compute)
+ This is the graphics and compute engine, i.e., the block that
+ encompasses the 3D pipeline and and shader blocks. This is by far the
+ largest block on the GPU. The 3D pipeline has tons of sub-blocks. In
+ addition to that, it also contains the CP microcontrollers (ME, PFP,
+ CE, MEC) and the RLC microcontroller. It's exposed to userspace for
+ user mode drivers (OpenGL, Vulkan, OpenCL, etc.)
+
+VCN (Video Core Next)
+ This is the multi-media engine. It handles video and image encode and
+ decode. It's exposed to userspace for user mode drivers (VA-API,
+ OpenMAX, etc.)
+
+Graphics and Compute Microcontrollers
+-------------------------------------
+
+CP (Command Processor)
+ The name for the hardware block that encompasses the front end of the
+ GFX/Compute pipeline. Consists mainly of a bunch of microcontrollers
+ (PFP, ME, CE, MEC). The firmware that runs on these microcontrollers
+ provides the driver interface to interact with the GFX/Compute engine.
+
+ MEC (MicroEngine Compute)
+ This is the microcontroller that controls the compute queues on the
+ GFX/compute engine.
+
+ MES (MicroEngine Scheduler)
+ This is a new engine for managing queues. This is currently unused.
+
+RLC (RunList Controller)
+ This is another microcontroller in the GFX/Compute engine. It handles
+ power management related functionality within the GFX/Compute engine.
+ The name is a vestige of old hardware where it was originally added
+ and doesn't really have much relation to what the engine does now.
+
+Driver Structure
+================
+
+In general, the driver has a list of all of the IPs on a particular
+SoC and for things like init/fini/suspend/resume, more or less just
+walks the list and handles each IP.
+
+Some useful constructs:
+
+KIQ (Kernel Interface Queue)
+ This is a control queue used by the kernel driver to manage other gfx
+ and compute queues on the GFX/compute engine. You can use it to
+ map/unmap additional queues, etc.
+
+IB (Indirect Buffer)
+ A command buffer for a particular engine. Rather than writing
+ commands directly to the queue, you can write the commands into a
+ piece of memory and then put a pointer to the memory into the queue.
+ The hardware will then follow the pointer and execute the commands in
+ the memory, then returning to the rest of the commands in the ring.

+ASUS mainboards publish hardware monitoring information via WMI interface.
+
+ASUS WMI interface provides a methods to get list of sensors and values of
+such, which is utilized by this driver to publish those sensor readings to the
+HWMON system.
+
+The driver is aware of and reads the following sensors:
+ * CPU Core Voltage,
+ * CPU SOC Voltage,
+ * DRAM Voltage,
+ * VDDP Voltage,
+ * 1.8V PLL Voltage,
+ * +12V Voltage,
+ * +5V Voltage,
+ * 3VSB Voltage,
+ * VBAT Voltage,
+ * AVCC3 Voltage,
+ * SB 1.05V Voltage,
+ * CPU Core Voltage,
+ * CPU SOC Voltage,
+ * DRAM Voltage,
+ * CPU Fan RPM,
+ * Chassis Fan 1 RPM,
+ * Chassis Fan 2 RPM,
+ * Chassis Fan 3 RPM,
+ * HAMP Fan RPM,
+ * Water Pump RPM,
+ * CPU OPT RPM,
+ * Water Flow RPM,
+ * AIO Pump RPM,
+ * CPU Temperature,

+ * Motherboard Temperature,
+ * Chipset Temperature,
+ * Tsensor 1 Temperature,
+ * CPU VRM Temperature,
+ * Water In,
+ * Water Out,
+ * CPU VRM Output Current.
+
+Known Issues:
+ * The WMI implementation in some of Asus' BIOSes is buggy. This can result in
+ fans stopping, fans getting stuck at max speed, or temperature readouts
+ getting stuck. This is not an issue with the driver, but the BIOS. The Prime
+ X470 Pro seems particularly bad for this. The more frequently the WMI
+ interface is polled the greater the potential for this to happen. Until you
+ have subjected your computer to an extended soak test while polling the
+ sensors frequently, don't leave you computer unattended. Upgrading to new
+ BIOS version with method version greater than or equal to two should
+ rectify the issue.
+ * A few boards report 12v voltages to be ~10v.

+Kernel driver nzxt-smart2
+=========================
+
+Supported devices:
+
+- NZXT RGB & Fan controller
+- NZXT Smart Device v2
+
+Description
+-----------
+
+This driver implements monitoring and control of fans plugged into the device.
+Besides typical speed monitoring and PWM duty cycle control, voltage and current
+is reported for every fan.
+
+The device also has two connectors for RGB LEDs; support for them isn't
+implemented (mainly because there is no standardized sysfs interface).
+
+Also, the device has a noise sensor, but the sensor seems to be completely
+useless (and very imprecise), so support for it isn't implemented too.
+
+Usage Notes
+-----------
+
+The device should be autodetected, and the driver should load automatically.
+
+If fans are plugged in/unplugged while the system is powered on, the driver
+must be reloaded to detect configuration changes; otherwise, new fans can't
+be controlled (`pwm*` changes will be ignored). It is necessary because the
+device has a dedicated "detect fans" command, and currently, it is executed only
+during initialization. Speed, voltage, current monitoring will work even without
+reload. As an alternative to reloading the module, a userspace tool (like
+`liquidctl`_) can be used to run "detect fans" command through hidraw interface.
+
+The driver coexists with userspace tools that access the device through hidraw
+interface with no known issues.

+Sysfs entries

+
+======================= ========================================================
+fan[1-3]_input Fan speed monitoring (in rpm).
+curr[1-3]_input Current supplied to the fan (in milliamperes).
+in[0-2]_input Voltage supplied to the fan (in millivolts).
+pwm[1-3] Controls fan speed: PWM duty cycle for PWM-controlled
+ fans, voltage for other fans. Voltage can be changed in
+ 9-12 V range, but the value of the sysfs attribute is
+ always in 0-255 range (1 = 9V, 255 = 12V). Setting the
+ attribute to 0 turns off the fan completely.
+pwm[1-3]_enable 1 if the fan can be controlled by writing to the
+ corresponding pwm* attribute, 0 otherwise. The device
+ can control only the fans it detected itself, so the
+ attribute is read-only.
+pwm[1-3]_mode Read-only, 1 for PWM-controlled fans, 0 for other fans
+ (or if no fan connected).
+update_interval The interval at which all inputs are updated (in
+ milliseconds). The default is 1000ms. Minimum is 250ms.

+
+On/off RTR frames reception
+===========================
+
+For most flexcan IP cores the driver supports 2 RX modes:
+
+- FIFO
+- mailbox
+
+The older flexcan cores (integrated into the i.MX25, i.MX28, i.MX35
+and i.MX53 SOCs) only receive RTR frames if the controller is
+configured for RX-FIFO mode.
+
+The RX FIFO mode uses a hardware FIFO with a depth of 6 CAN frames,
+while the mailbox mode uses a software FIFO with a depth of up to 62
+CAN frames. With the help of the bigger buffer, the mailbox mode
+performs better under high system load situations.
+
+As reception of RTR frames is part of the CAN standard, all flexcan
+cores come up in a mode where RTR reception is possible.
+
+With the "rx-rtr" private flag the ability to receive RTR frames can
+be waived at the expense of losing the ability to receive RTR
+messages. This trade off is beneficial in certain use cases.
+
+"rx-rtr" on
+ Receive RTR frames. (default)
+
+ The CAN controller can and will receive RTR frames.
+
+ On some IP cores the controller cannot receive RTR frames in the
+ more performant "RX mailbox" mode and will use "RX FIFO" mode
+ instead.
+
+"rx-rtr" off
+
+ Waive ability to receive RTR frames. (not supported on all IP cores)
+
+ This mode activates the "RX mailbox mode" for better performance, on
+ some IP cores RTR frames cannot be received anymore.

+
+ ip link set dev can0 down
+ ethtool --set-priv-flags can0 rx-rtr {off|on}

originates from [e]xtended BPF is not the same as BPF extensions! While

sparc64, arm32, riscv64, riscv32 perform JIT compilation from eBPF
instruction set.
-Some core changes of the new internal format:
-
-- Number of registers increase from 2 to 10:
-
- The old format had two registers A and X, and a hidden frame pointer. The
- new layout extends this to be 10 internal registers and a read-only frame
- pointer. Since 64-bit CPUs are passing arguments to functions via registers
- the number of args from eBPF program to in-kernel function is restricted
- to 5 and one register is used to accept return value from an in-kernel
- function. Natively, x86_64 passes first 6 arguments in registers, aarch64/
- sparcv9/mips64 have 7 - 8 registers for arguments; x86_64 has 6 callee saved
- registers, and aarch64/sparcv9/mips64 have 11 or more callee saved registers.
-
- Therefore, eBPF calling convention is defined as:
-
- * R0 - return value from in-kernel function, and exit value for eBPF program
- * R1 - R5 - arguments from eBPF program to in-kernel function
- * R6 - R9 - callee saved registers that in-kernel function will preserve
- * R10 - read-only frame pointer to access stack
-
- Thus, all eBPF registers map one to one to HW registers on x86_64, aarch64,
- etc, and eBPF calling convention maps directly to ABIs used by the kernel on
- 64-bit architectures.
-
- On 32-bit architectures JIT may map programs that use only 32-bit arithmetic
- and may let more complex programs to be interpreted.
-
- R0 - R5 are scratch registers and eBPF program needs spill/fill them if
- necessary across calls. Note that there is only one eBPF program (== one
- eBPF main routine) and it cannot call other eBPF functions, it can only
- call predefined in-kernel functions, though.
-
-- Register width increases from 32-bit to 64-bit:
-
- Still, the semantics of the original 32-bit ALU operations are preserved
- via 32-bit subregisters. All eBPF registers are 64-bit with 32-bit lower
- subregisters that zero-extend into 64-bit if they are being written to.
- That behavior maps directly to x86_64 and arm64 subregister definition, but
- makes other JITs more difficult.
-
- 32-bit architectures run 64-bit internal BPF programs via interpreter.
- Their JITs may convert BPF programs that only use 32-bit subregisters into
- native instruction set and let the rest being interpreted.
-
- Operation is 64-bit, because on 64-bit architectures, pointers are also
- 64-bit wide, and we want to pass 64-bit values in/out of kernel functions,
- so 32-bit eBPF registers would otherwise require to define register-pair
- ABI, thus, there won't be able to use a direct eBPF register to HW register
- mapping and JIT would need to do combine/split/move operations for every
- register in and out of the function, which is complex, bug prone and slow.
- Another reason is the use of atomic 64-bit counters.
-
-- Conditional jt/jf targets replaced with jt/fall-through:
-
- While the original design has constructs such as ``if (cond) jump_true;
- else jump_false;``, they are being replaced into alternative constructs like
- ``if (cond) jump_true; /* else fall-through */``.
-
-- Introduces bpf_call insn and register passing convention for zero overhead
- calls from/to other kernel functions:
-
- Before an in-kernel function call, the internal BPF program needs to
- place function arguments into R1 to R5 registers to satisfy calling
- convention, then the interpreter will take them from registers and pass
- to in-kernel function. If R1 - R5 registers are mapped to CPU registers
- that are used for argument passing on given architecture, the JIT compiler
- doesn't need to emit extra moves. Function arguments will be in the correct
- registers and BPF_CALL instruction will be JITed as single 'call' HW
- instruction. This calling convention was picked to cover common call
- situations without performance penalty.
-
- After an in-kernel function call, R1 - R5 are reset to unreadable and R0 has
- a return value of the function. Since R6 - R9 are callee saved, their state
- is preserved across the call.
-
- For example, consider three C functions::
-
- u64 f1() { return (*_f2)(1); }
- u64 f2(u64 a) { return f3(a + 1, a); }
- u64 f3(u64 a, u64 b) { return a - b; }
-
- GCC can compile f1, f3 into x86_64::
-
- f1:
- movl $1, %edi
- movq _f2(%rip), %rax
- jmp *%rax
- f3:
- movq %rdi, %rax
- subq %rsi, %rax
- ret
-
- Function f2 in eBPF may look like::
-
- f2:
- bpf_mov R2, R1
- bpf_add R1, 1
- bpf_call f3
- bpf_exit
-
- If f2 is JITed and the pointer stored to ``_f2``. The calls f1 -> f2 -> f3 and
- returns will be seamless. Without JIT, __bpf_prog_run() interpreter needs to
- be used to call into f2.
-
- For practical reasons all eBPF programs have only one argument 'ctx' which is
- already placed into R1 (e.g. on __bpf_prog_run() startup) and the programs
- can call kernel functions with up to 5 arguments. Calls with 6 or more arguments
- are currently not supported, but these restrictions can be lifted if necessary
- in the future.
-
- On 64-bit architectures all register map to HW registers one to one. For
- example, x86_64 JIT compiler can map them as ...
-
- ::
-
- R0 - rax
- R1 - rdi
- R2 - rsi
- R3 - rdx
- R4 - rcx
- R5 - r8
- R6 - rbx
- R7 - r13
- R8 - r14
- R9 - r15
- R10 - rbp
-
- ... since x86_64 ABI mandates rdi, rsi, rdx, rcx, r8, r9 for argument passing
- and rbx, r12 - r15 are callee saved.
-
- Then the following internal BPF pseudo-program::
-
- bpf_mov R6, R1 /* save ctx */
- bpf_mov R2, 2
- bpf_mov R3, 3
- bpf_mov R4, 4
- bpf_mov R5, 5
- bpf_call foo
- bpf_mov R7, R0 /* save foo() return value */
- bpf_mov R1, R6 /* restore ctx for next call */
- bpf_mov R2, 6
- bpf_mov R3, 7
- bpf_mov R4, 8
- bpf_mov R5, 9
- bpf_call bar
- bpf_add R0, R7
- bpf_exit
-
- After JIT to x86_64 may look like::
-
- push %rbp
- mov %rsp,%rbp
- sub $0x228,%rsp
- mov %rbx,-0x228(%rbp)
- mov %r13,-0x220(%rbp)
- mov %rdi,%rbx
- mov $0x2,%esi
- mov $0x3,%edx
- mov $0x4,%ecx
- mov $0x5,%r8d
- callq foo
- mov %rax,%r13
- mov %rbx,%rdi
- mov $0x6,%esi
- mov $0x7,%edx
- mov $0x8,%ecx
- mov $0x9,%r8d
- callq bar
- add %r13,%rax
- mov -0x228(%rbp),%rbx
- mov -0x220(%rbp),%r13
- leaveq
- retq
-
- Which is in this example equivalent in C to::
-
- u64 bpf_filter(u64 ctx)
- {
- return foo(ctx, 2, 3, 4, 5) + bar(ctx, 6, 7, 8, 9);
- }
-
- In-kernel functions foo() and bar() with prototype: u64 (*)(u64 arg1, u64
- arg2, u64 arg3, u64 arg4, u64 arg5); will receive arguments in proper
- registers and place their return value into ``%rax`` which is R0 in eBPF.
- Prologue and epilogue are emitted by JIT and are implicit in the
- interpreter. R0-R5 are scratch registers, so eBPF program needs to preserve
- them across the calls as defined by calling convention.
-
- For example the following program is invalid::
-
- bpf_mov R1, 1
- bpf_call foo
- bpf_mov R0, R1
- bpf_exit
-
- After the call the registers R1-R5 contain junk values and cannot be read.
- An in-kernel eBPF verifier is used to validate internal BPF programs.
-
-Also in the new design, eBPF is limited to 4096 insns, which means that any
-program will terminate quickly and will only call a fixed number of kernel
-functions. Original BPF and the new format are two operand instructions,
-which helps to do one-to-one mapping between eBPF insn and x86 insn during JIT.
-
-The input context pointer for invoking the interpreter function is generic,
-its content is defined by a specific use case. For seccomp register R1 points
-to seccomp_data, for converted BPF filters R1 points to a skb.
-
-A program, that is translated internally consists of the following elements::
-
- op:16, jt:8, jf:8, k:32 ==> op:8, dst_reg:4, src_reg:4, off:16, imm:32
-
-So far 87 internal BPF instructions were implemented. 8-bit 'op' opcode field
-has room for new instructions. Some of them may use 16/24/32 byte encoding. New
-instructions must be multiple of 8 bytes to preserve backward compatibility.
-
-Internal BPF is a general purpose RISC instruction set. Not every register and
-every instruction are used during translation from original BPF to new format.
-For example, socket filters are not using ``exclusive add`` instruction, but
-tracing filters may do to maintain counters of events, for example. Register R9
-is not used by socket filters either, but more complex filters may be running
-out of registers and would have to resort to spill/fill to stack.
-
-Internal BPF can be used as a generic assembler for last step performance
-optimizations, socket filters and seccomp are using it as assembler. Tracing
-filters may use it as assembler to generate code from kernel. In kernel usage
-may not be bounded by security considerations, since generated internal BPF code
-may be optimizing internal code path and not being exposed to the user space.
-Safety of internal BPF can come from a verifier (TBD). In such use cases as
-described, it may be used as safe instruction set.
-
-Just like the original BPF, the new format runs within a controlled environment,
-is deterministic and the kernel can easily prove that. The safety of the program
-can be determined in two steps: first step does depth-first-search to disallow
-loops and other CFG validation; second step starts from the first insn and
-descends all possible paths. It simulates execution of every insn and observes
-the state change of registers and stack.

-eBPF opcode encoding
---------------------
-
-eBPF is reusing most of the opcode encoding from classic to simplify conversion
-of classic BPF to eBPF. For arithmetic and jump instructions the 8-bit 'code'
-field is divided into three parts::
-
- +----------------+--------+--------------------+
- | 4 bits | 1 bit | 3 bits |
- | operation code | source | instruction class |
- +----------------+--------+--------------------+
- (MSB) (LSB)
-
-Three LSB bits store instruction class which is one of:
-
- =================== ===============
- Classic BPF classes eBPF classes
- =================== ===============
- BPF_LD 0x00 BPF_LD 0x00
- BPF_LDX 0x01 BPF_LDX 0x01
- BPF_ST 0x02 BPF_ST 0x02
- BPF_STX 0x03 BPF_STX 0x03
- BPF_ALU 0x04 BPF_ALU 0x04
- BPF_JMP 0x05 BPF_JMP 0x05
- BPF_RET 0x06 BPF_JMP32 0x06
- BPF_MISC 0x07 BPF_ALU64 0x07
- =================== ===============
-
-When BPF_CLASS(code) == BPF_ALU or BPF_JMP, 4th bit encodes source operand ...
-
- ::
-
- BPF_K 0x00
- BPF_X 0x08
-
- * in classic BPF, this means::
-
- BPF_SRC(code) == BPF_X - use register X as source operand
- BPF_SRC(code) == BPF_K - use 32-bit immediate as source operand
-
- * in eBPF, this means::
-
- BPF_SRC(code) == BPF_X - use 'src_reg' register as source operand
- BPF_SRC(code) == BPF_K - use 32-bit immediate as source operand
-
-... and four MSB bits store operation code.
-
-If BPF_CLASS(code) == BPF_ALU or BPF_ALU64 [ in eBPF ], BPF_OP(code) is one of::
-
- BPF_ADD 0x00
- BPF_SUB 0x10
- BPF_MUL 0x20
- BPF_DIV 0x30
- BPF_OR 0x40
- BPF_AND 0x50
- BPF_LSH 0x60
- BPF_RSH 0x70
- BPF_NEG 0x80
- BPF_MOD 0x90
- BPF_XOR 0xa0
- BPF_MOV 0xb0 /* eBPF only: mov reg to reg */
- BPF_ARSH 0xc0 /* eBPF only: sign extending shift right */
- BPF_END 0xd0 /* eBPF only: endianness conversion */
-
-If BPF_CLASS(code) == BPF_JMP or BPF_JMP32 [ in eBPF ], BPF_OP(code) is one of::
-
- BPF_JA 0x00 /* BPF_JMP only */
- BPF_JEQ 0x10
- BPF_JGT 0x20
- BPF_JGE 0x30
- BPF_JSET 0x40
- BPF_JNE 0x50 /* eBPF only: jump != */
- BPF_JSGT 0x60 /* eBPF only: signed '>' */
- BPF_JSGE 0x70 /* eBPF only: signed '>=' */
- BPF_CALL 0x80 /* eBPF BPF_JMP only: function call */
- BPF_EXIT 0x90 /* eBPF BPF_JMP only: function return */
- BPF_JLT 0xa0 /* eBPF only: unsigned '<' */
- BPF_JLE 0xb0 /* eBPF only: unsigned '<=' */
- BPF_JSLT 0xc0 /* eBPF only: signed '<' */
- BPF_JSLE 0xd0 /* eBPF only: signed '<=' */
-
-So BPF_ADD | BPF_X | BPF_ALU means 32-bit addition in both classic BPF
-and eBPF. There are only two registers in classic BPF, so it means A += X.
-In eBPF it means dst_reg = (u32) dst_reg + (u32) src_reg; similarly,
-BPF_XOR | BPF_K | BPF_ALU means A ^= imm32 in classic BPF and analogous
-src_reg = (u32) src_reg ^ (u32) imm32 in eBPF.
-
-Classic BPF is using BPF_MISC class to represent A = X and X = A moves.
-eBPF is using BPF_MOV | BPF_X | BPF_ALU code instead. Since there are no
-BPF_MISC operations in eBPF, the class 7 is used as BPF_ALU64 to mean
-exactly the same operations as BPF_ALU, but with 64-bit wide operands
-instead. So BPF_ADD | BPF_X | BPF_ALU64 means 64-bit addition, i.e.:
-dst_reg = dst_reg + src_reg
-
-Classic BPF wastes the whole BPF_RET class to represent a single ``ret``
-operation. Classic BPF_RET | BPF_K means copy imm32 into return register
-and perform function exit. eBPF is modeled to match CPU, so BPF_JMP | BPF_EXIT
-in eBPF means function exit only. The eBPF program needs to store return
-value into register R0 before doing a BPF_EXIT. Class 6 in eBPF is used as
-BPF_JMP32 to mean exactly the same operations as BPF_JMP, but with 32-bit wide
-operands for the comparisons instead.
-
-For load and store instructions the 8-bit 'code' field is divided as::
-
- +--------+--------+-------------------+
- | 3 bits | 2 bits | 3 bits |
- | mode | size | instruction class |
- +--------+--------+-------------------+
- (MSB) (LSB)
-
-Size modifier is one of ...
-
-::
-
- BPF_W 0x00 /* word */
- BPF_H 0x08 /* half word */
- BPF_B 0x10 /* byte */
- BPF_DW 0x18 /* eBPF only, double word */
-
-... which encodes size of load/store operation::
-
- B - 1 byte
- H - 2 byte
- W - 4 byte
- DW - 8 byte (eBPF only)
-
-Mode modifier is one of::
-
- BPF_IMM 0x00 /* used for 32-bit mov in classic BPF and 64-bit in eBPF */
- BPF_ABS 0x20
- BPF_IND 0x40
- BPF_MEM 0x60
- BPF_LEN 0x80 /* classic BPF only, reserved in eBPF */
- BPF_MSH 0xa0 /* classic BPF only, reserved in eBPF */
- BPF_ATOMIC 0xc0 /* eBPF only, atomic operations */
-
-eBPF has two non-generic instructions: (BPF_ABS | <size> | BPF_LD) and
-(BPF_IND | <size> | BPF_LD) which are used to access packet data.
-
-They had to be carried over from classic to have strong performance of
-socket filters running in eBPF interpreter. These instructions can only
-be used when interpreter context is a pointer to ``struct sk_buff`` and
-have seven implicit operands. Register R6 is an implicit input that must
-contain pointer to sk_buff. Register R0 is an implicit output which contains
-the data fetched from the packet. Registers R1-R5 are scratch registers
-and must not be used to store the data across BPF_ABS | BPF_LD or
-BPF_IND | BPF_LD instructions.
-
-These instructions have implicit program exit condition as well. When
-eBPF program is trying to access the data beyond the packet boundary,
-the interpreter will abort the execution of the program. JIT compilers
-therefore must preserve this property. src_reg and imm32 fields are
-explicit inputs to these instructions.
-
-For example::
-
- BPF_IND | BPF_W | BPF_LD means:
-
- R0 = ntohl(*(u32 *) (((struct sk_buff *) R6)->data + src_reg + imm32))
- and R1 - R5 were scratched.
-
-Unlike classic BPF instruction set, eBPF has generic load/store operations::
-
- BPF_MEM | <size> | BPF_STX: *(size *) (dst_reg + off) = src_reg
- BPF_MEM | <size> | BPF_ST: *(size *) (dst_reg + off) = imm32
- BPF_MEM | <size> | BPF_LDX: dst_reg = *(size *) (src_reg + off)
-
-Where size is one of: BPF_B or BPF_H or BPF_W or BPF_DW.
-
-It also includes atomic operations, which use the immediate field for extra
-encoding::
-
- .imm = BPF_ADD, .code = BPF_ATOMIC | BPF_W | BPF_STX: lock xadd *(u32 *)(dst_reg + off16) += src_reg
- .imm = BPF_ADD, .code = BPF_ATOMIC | BPF_DW | BPF_STX: lock xadd *(u64 *)(dst_reg + off16) += src_reg
-
-The basic atomic operations supported are::
-
- BPF_ADD
- BPF_AND
- BPF_OR
- BPF_XOR
-
-Each having equivalent semantics with the ``BPF_ADD`` example, that is: the
-memory location addresed by ``dst_reg + off`` is atomically modified, with
-``src_reg`` as the other operand. If the ``BPF_FETCH`` flag is set in the
-immediate, then these operations also overwrite ``src_reg`` with the
-value that was in memory before it was modified.
-
-The more special operations are::
-
- BPF_XCHG
-
-This atomically exchanges ``src_reg`` with the value addressed by ``dst_reg +
-off``. ::
-
- BPF_CMPXCHG
-
-This atomically compares the value addressed by ``dst_reg + off`` with
-``R0``. If they match it is replaced with ``src_reg``. In either case, the
-value that was there before is zero-extended and loaded back to ``R0``.
-
-Note that 1 and 2 byte atomic operations are not supported.
-
-Clang can generate atomic instructions by default when ``-mcpu=v3`` is
-enabled. If a lower version for ``-mcpu`` is set, the only atomic instruction
-Clang can generate is ``BPF_ADD`` *without* ``BPF_FETCH``. If you need to enable
-the atomics features, while keeping a lower ``-mcpu`` version, you can use
-``-Xclang -target-feature -Xclang +alu32``.
-
-You may encounter ``BPF_XADD`` - this is a legacy name for ``BPF_ATOMIC``,
-referring to the exclusive-add operation encoded when the immediate field is
-zero.
-
-eBPF has one 16-byte instruction: ``BPF_LD | BPF_DW | BPF_IMM`` which consists
-of two consecutive ``struct bpf_insn`` 8-byte blocks and interpreted as single
-instruction that loads 64-bit immediate value into a dst_reg.
-Classic BPF has similar instruction: ``BPF_LD | BPF_W | BPF_IMM`` which loads
-32-bit immediate value into a register.
-
-eBPF verifier
--------------
-The safety of the eBPF program is determined in two steps.
-
-First step does DAG check to disallow loops and other CFG validation.
-In particular it will detect programs that have unreachable instructions.
-(though classic BPF checker allows them)
-
-Second step starts from the first insn and descends all possible paths.
-It simulates execution of every insn and observes the state change of
-registers and stack.
-
-At the start of the program the register R1 contains a pointer to context
-and has type PTR_TO_CTX.
-If verifier sees an insn that does R2=R1, then R2 has now type
-PTR_TO_CTX as well and can be used on the right hand side of expression.
-If R1=PTR_TO_CTX and insn is R2=R1+R1, then R2=SCALAR_VALUE,
-since addition of two valid pointers makes invalid pointer.
-(In 'secure' mode verifier will reject any type of pointer arithmetic to make
-sure that kernel addresses don't leak to unprivileged users)
-
-If register was never written to, it's not readable::
-
- bpf_mov R0 = R2
- bpf_exit
-
-will be rejected, since R2 is unreadable at the start of the program.
-
-After kernel function call, R1-R5 are reset to unreadable and
-R0 has a return type of the function.
-
-Since R6-R9 are callee saved, their state is preserved across the call.
-
-::
-
- bpf_mov R6 = 1
- bpf_call foo
- bpf_mov R0 = R6
- bpf_exit
-
-is a correct program. If there was R1 instead of R6, it would have
-been rejected.
-
-load/store instructions are allowed only with registers of valid types, which
-are PTR_TO_CTX, PTR_TO_MAP, PTR_TO_STACK. They are bounds and alignment checked.
-For example::
-
- bpf_mov R1 = 1
- bpf_mov R2 = 2
- bpf_xadd *(u32 *)(R1 + 3) += R2
- bpf_exit
-
-will be rejected, since R1 doesn't have a valid pointer type at the time of
-execution of instruction bpf_xadd.
-
-At the start R1 type is PTR_TO_CTX (a pointer to generic ``struct bpf_context``)
-A callback is used to customize verifier to restrict eBPF program access to only
-certain fields within ctx structure with specified size and alignment.
-
-For example, the following insn::
-
- bpf_ld R0 = *(u32 *)(R6 + 8)
-
-intends to load a word from address R6 + 8 and store it into R0
-If R6=PTR_TO_CTX, via is_valid_access() callback the verifier will know
-that offset 8 of size 4 bytes can be accessed for reading, otherwise
-the verifier will reject the program.
-If R6=PTR_TO_STACK, then access should be aligned and be within
-stack bounds, which are [-MAX_BPF_STACK, 0). In this example offset is 8,
-so it will fail verification, since it's out of bounds.
-
-The verifier will allow eBPF program to read data from stack only after
-it wrote into it.
-
-Classic BPF verifier does similar check with M[0-15] memory slots.
-For example::
-
- bpf_ld R0 = *(u32 *)(R10 - 4)
- bpf_exit
-
-is invalid program.
-Though R10 is correct read-only register and has type PTR_TO_STACK
-and R10 - 4 is within stack bounds, there were no stores into that location.
-
-Pointer register spill/fill is tracked as well, since four (R6-R9)
-callee saved registers may not be enough for some programs.
-
-Allowed function calls are customized with bpf_verifier_ops->get_func_proto()
-The eBPF verifier will check that registers match argument constraints.
-After the call register R0 will be set to return type of the function.
-
-Function calls is a main mechanism to extend functionality of eBPF programs.
-Socket filters may let programs to call one set of functions, whereas tracing
-filters may allow completely different set.
-
-If a function made accessible to eBPF program, it needs to be thought through
-from safety point of view. The verifier will guarantee that the function is
-called with valid arguments.
-
-seccomp vs socket filters have different security restrictions for classic BPF.
-Seccomp solves this by two stage verifier: classic BPF verifier is followed
-by seccomp verifier. In case of eBPF one configurable verifier is shared for
-all use cases.
-
-See details of eBPF verifier in kernel/bpf/verifier.c
-
-Register value tracking
------------------------
-In order to determine the safety of an eBPF program, the verifier must track
-the range of possible values in each register and also in each stack slot.
-This is done with ``struct bpf_reg_state``, defined in include/linux/
-bpf_verifier.h, which unifies tracking of scalar and pointer values. Each
-register state has a type, which is either NOT_INIT (the register has not been
-written to), SCALAR_VALUE (some value which is not usable as a pointer), or a
-pointer type. The types of pointers describe their base, as follows:
-
-
- PTR_TO_CTX
- Pointer to bpf_context.
- CONST_PTR_TO_MAP
- Pointer to struct bpf_map. "Const" because arithmetic
- on these pointers is forbidden.
- PTR_TO_MAP_VALUE
- Pointer to the value stored in a map element.
- PTR_TO_MAP_VALUE_OR_NULL
- Either a pointer to a map value, or NULL; map accesses
- (see section 'eBPF maps', below) return this type,
- which becomes a PTR_TO_MAP_VALUE when checked != NULL.
- Arithmetic on these pointers is forbidden.
- PTR_TO_STACK
- Frame pointer.
- PTR_TO_PACKET
- skb->data.
- PTR_TO_PACKET_END
- skb->data + headlen; arithmetic forbidden.
- PTR_TO_SOCKET
- Pointer to struct bpf_sock_ops, implicitly refcounted.
- PTR_TO_SOCKET_OR_NULL
- Either a pointer to a socket, or NULL; socket lookup
- returns this type, which becomes a PTR_TO_SOCKET when
- checked != NULL. PTR_TO_SOCKET is reference-counted,
- so programs must release the reference through the
- socket release function before the end of the program.
- Arithmetic on these pointers is forbidden.
-
-However, a pointer may be offset from this base (as a result of pointer
-arithmetic), and this is tracked in two parts: the 'fixed offset' and 'variable
-offset'. The former is used when an exactly-known value (e.g. an immediate
-operand) is added to a pointer, while the latter is used for values which are
-not exactly known. The variable offset is also used in SCALAR_VALUEs, to track
-the range of possible values in the register.
-
-The verifier's knowledge about the variable offset consists of:
-
-* minimum and maximum values as unsigned
-* minimum and maximum values as signed
-
-* knowledge of the values of individual bits, in the form of a 'tnum': a u64
- 'mask' and a u64 'value'. 1s in the mask represent bits whose value is unknown;
- 1s in the value represent bits known to be 1. Bits known to be 0 have 0 in both
- mask and value; no bit should ever be 1 in both. For example, if a byte is read
- into a register from memory, the register's top 56 bits are known zero, while
- the low 8 are unknown - which is represented as the tnum (0x0; 0xff). If we
- then OR this with 0x40, we get (0x40; 0xbf), then if we add 1 we get (0x0;
- 0x1ff), because of potential carries.
-
-Besides arithmetic, the register state can also be updated by conditional
-branches. For instance, if a SCALAR_VALUE is compared > 8, in the 'true' branch
-it will have a umin_value (unsigned minimum value) of 9, whereas in the 'false'
-branch it will have a umax_value of 8. A signed compare (with BPF_JSGT or
-BPF_JSGE) would instead update the signed minimum/maximum values. Information
-from the signed and unsigned bounds can be combined; for instance if a value is
-first tested < 8 and then tested s> 4, the verifier will conclude that the value
-is also > 4 and s< 8, since the bounds prevent crossing the sign boundary.
-
-PTR_TO_PACKETs with a variable offset part have an 'id', which is common to all
-pointers sharing that same variable offset. This is important for packet range
-checks: after adding a variable to a packet pointer register A, if you then copy
-it to another register B and then add a constant 4 to A, both registers will
-share the same 'id' but the A will have a fixed offset of +4. Then if A is
-bounds-checked and found to be less than a PTR_TO_PACKET_END, the register B is
-now known to have a safe range of at least 4 bytes. See 'Direct packet access',
-below, for more on PTR_TO_PACKET ranges.
-
-The 'id' field is also used on PTR_TO_MAP_VALUE_OR_NULL, common to all copies of
-the pointer returned from a map lookup. This means that when one copy is
-checked and found to be non-NULL, all copies can become PTR_TO_MAP_VALUEs.
-As well as range-checking, the tracked information is also used for enforcing
-alignment of pointer accesses. For instance, on most systems the packet pointer
-is 2 bytes after a 4-byte alignment. If a program adds 14 bytes to that to jump
-over the Ethernet header, then reads IHL and addes (IHL * 4), the resulting
-pointer will have a variable offset known to be 4n+2 for some n, so adding the 2
-bytes (NET_IP_ALIGN) gives a 4-byte alignment and so word-sized accesses through
-that pointer are safe.
-The 'id' field is also used on PTR_TO_SOCKET and PTR_TO_SOCKET_OR_NULL, common
-to all copies of the pointer returned from a socket lookup. This has similar
-behaviour to the handling for PTR_TO_MAP_VALUE_OR_NULL->PTR_TO_MAP_VALUE, but
-it also handles reference tracking for the pointer. PTR_TO_SOCKET implicitly
-represents a reference to the corresponding ``struct sock``. To ensure that the
-reference is not leaked, it is imperative to NULL-check the reference and in
-the non-NULL case, and pass the valid reference to the socket release function.
-
-Direct packet access
---------------------
-In cls_bpf and act_bpf programs the verifier allows direct access to the packet
-data via skb->data and skb->data_end pointers.
-Ex::
-
- 1: r4 = *(u32 *)(r1 +80) /* load skb->data_end */
- 2: r3 = *(u32 *)(r1 +76) /* load skb->data */
- 3: r5 = r3
- 4: r5 += 14
- 5: if r5 > r4 goto pc+16
- R1=ctx R3=pkt(id=0,off=0,r=14) R4=pkt_end R5=pkt(id=0,off=14,r=14) R10=fp
- 6: r0 = *(u16 *)(r3 +12) /* access 12 and 13 bytes of the packet */
-
-this 2byte load from the packet is safe to do, since the program author
-did check ``if (skb->data + 14 > skb->data_end) goto err`` at insn #5 which
-means that in the fall-through case the register R3 (which points to skb->data)
-has at least 14 directly accessible bytes. The verifier marks it
-as R3=pkt(id=0,off=0,r=14).
-id=0 means that no additional variables were added to the register.
-off=0 means that no additional constants were added.
-r=14 is the range of safe access which means that bytes [R3, R3 + 14) are ok.
-Note that R5 is marked as R5=pkt(id=0,off=14,r=14). It also points
-to the packet data, but constant 14 was added to the register, so
-it now points to ``skb->data + 14`` and accessible range is [R5, R5 + 14 - 14)
-which is zero bytes.
-
-More complex packet access may look like::
-
-
- R0=inv1 R1=ctx R3=pkt(id=0,off=0,r=14) R4=pkt_end R5=pkt(id=0,off=14,r=14) R10=fp
- 6: r0 = *(u8 *)(r3 +7) /* load 7th byte from the packet */
- 7: r4 = *(u8 *)(r3 +12)
- 8: r4 *= 14
- 9: r3 = *(u32 *)(r1 +76) /* load skb->data */
- 10: r3 += r4
- 11: r2 = r1
- 12: r2 <<= 48
- 13: r2 >>= 48
- 14: r3 += r2
- 15: r2 = r3
- 16: r2 += 8
- 17: r1 = *(u32 *)(r1 +80) /* load skb->data_end */
- 18: if r2 > r1 goto pc+2
- R0=inv(id=0,umax_value=255,var_off=(0x0; 0xff)) R1=pkt_end R2=pkt(id=2,off=8,r=8) R3=pkt(id=2,off=0,r=8) R4=inv(id=0,umax_value=3570,var_off=(0x0; 0xfffe)) R5=pkt(id=0,off=14,r=14) R10=fp
- 19: r1 = *(u8 *)(r3 +4)
-
-The state of the register R3 is R3=pkt(id=2,off=0,r=8)
-id=2 means that two ``r3 += rX`` instructions were seen, so r3 points to some
-offset within a packet and since the program author did
-``if (r3 + 8 > r1) goto err`` at insn #18, the safe range is [R3, R3 + 8).
-The verifier only allows 'add'/'sub' operations on packet registers. Any other
-operation will set the register state to 'SCALAR_VALUE' and it won't be
-available for direct packet access.
-
-Operation ``r3 += rX`` may overflow and become less than original skb->data,
-therefore the verifier has to prevent that. So when it sees ``r3 += rX``
-instruction and rX is more than 16-bit value, any subsequent bounds-check of r3
-against skb->data_end will not give us 'range' information, so attempts to read
-through the pointer will give "invalid access to packet" error.
-
-Ex. after insn ``r4 = *(u8 *)(r3 +12)`` (insn #7 above) the state of r4 is
-R4=inv(id=0,umax_value=255,var_off=(0x0; 0xff)) which means that upper 56 bits
-of the register are guaranteed to be zero, and nothing is known about the lower
-8 bits. After insn ``r4 *= 14`` the state becomes
-R4=inv(id=0,umax_value=3570,var_off=(0x0; 0xfffe)), since multiplying an 8-bit
-value by constant 14 will keep upper 52 bits as zero, also the least significant
-bit will be zero as 14 is even. Similarly ``r2 >>= 48`` will make
-R2=inv(id=0,umax_value=65535,var_off=(0x0; 0xffff)), since the shift is not sign
-extending. This logic is implemented in adjust_reg_min_max_vals() function,
-which calls adjust_ptr_min_max_vals() for adding pointer to scalar (or vice
-versa) and adjust_scalar_min_max_vals() for operations on two scalars.
-
-The end result is that bpf program author can access packet directly
-using normal C code as::
-
- void *data = (void *)(long)skb->data;
- void *data_end = (void *)(long)skb->data_end;
- struct eth_hdr *eth = data;
- struct iphdr *iph = data + sizeof(*eth);
- struct udphdr *udp = data + sizeof(*eth) + sizeof(*iph);
-
- if (data + sizeof(*eth) + sizeof(*iph) + sizeof(*udp) > data_end)
- return 0;

-eBPF maps
----------
-'maps' is a generic storage of different types for sharing data between kernel
-and userspace.
-
-The maps are accessed from user space via BPF syscall, which has commands:
-
-- create a map with given type and attributes
- ``map_fd = bpf(BPF_MAP_CREATE, union bpf_attr *attr, u32 size)``
- using attr->map_type, attr->key_size, attr->value_size, attr->max_entries
- returns process-local file descriptor or negative error
-
-- lookup key in a given map
- ``err = bpf(BPF_MAP_LOOKUP_ELEM, union bpf_attr *attr, u32 size)``
- using attr->map_fd, attr->key, attr->value
- returns zero and stores found elem into value or negative error
-
-- create or update key/value pair in a given map
- ``err = bpf(BPF_MAP_UPDATE_ELEM, union bpf_attr *attr, u32 size)``
- using attr->map_fd, attr->key, attr->value
- returns zero or negative error
-
-- find and delete element by key in a given map
- ``err = bpf(BPF_MAP_DELETE_ELEM, union bpf_attr *attr, u32 size)``
- using attr->map_fd, attr->key
-
-- to delete map: close(fd)
- Exiting process will delete maps automatically
-
-userspace programs use this syscall to create/access maps that eBPF programs
-are concurrently updating.
-
-maps can have different types: hash, array, bloom filter, radix-tree, etc.
-
-The map is defined by:
-
- - type
- - max number of elements
- - key size in bytes
- - value size in bytes
-
-Pruning
--------
-The verifier does not actually walk all possible paths through the program. For
-each new branch to analyse, the verifier looks at all the states it's previously
-been in when at this instruction. If any of them contain the current state as a
-subset, the branch is 'pruned' - that is, the fact that the previous state was
-accepted implies the current state would be as well. For instance, if in the
-previous state, r1 held a packet-pointer, and in the current state, r1 holds a
-packet-pointer with a range as long or longer and at least as strict an
-alignment, then r1 is safe. Similarly, if r2 was NOT_INIT before then it can't
-have been used by any path from that point, so any value in r2 (including
-another NOT_INIT) is safe. The implementation is in the function regsafe().
-Pruning considers not only the registers but also the stack (and any spilled
-registers it may hold). They must all be safe for the branch to be pruned.
-This is implemented in states_equal().

DEVICE CREATION, DRIVER BINDING
===============================
-The simplest way to arrange to use this driver is to just list it in the
-spi_board_info for a device as the driver it should use: the "modalias"
-entry is "spidev", matching the name of the driver exposing this API.
-Set up the other device characteristics (bits per word, SPI clocking,
-chipselect polarity, etc) as usual, so you won't always need to override
-them later.
-
-(Sysfs also supports userspace driven binding/unbinding of drivers to
-devices. That mechanism might be supported here in the future.)
-
-When you do that, the sysfs node for the SPI device will include a child
-device node with a "dev" attribute that will be understood by udev or mdev.
-(Larger systems will have "udev". Smaller ones may configure "mdev" into
-busybox; it's less featureful, but often enough.) For a SPI device with
-chipselect C on bus B, you should see:
+
+The spidev driver contains lists of SPI devices that are supported for
+the different hardware topology representations.
+
+The following are the SPI device tables supported by the spidev driver:
+
+ - struct spi_device_id spidev_spi_ids[]: list of devices that can be
+ bound when these are defined using a struct spi_board_info with a
+ .modalias field matching one of the entries in the table.
+
+ - struct of_device_id spidev_dt_ids[]: list of devices that can be
+ bound when these are defined using a Device Tree node that has a
+ compatible string matching one of the entries in the table.
+
+ - struct acpi_device_id spidev_acpi_ids[]: list of devices that can
+ be bound when these are defined using a ACPI device object with a
+ _HID matching one of the entries in the table.
+
+You are encouraged to add an entry for your SPI device name to relevant
+tables, if these don't already have an entry for the device. To do that,
+post a patch for spidev to the linux-spi@vger.kernel.org mailing list.
+
+It used to be supported to define an SPI device using the "spidev" name.
+For example, as .modalias = "spidev" or compatible = "spidev". But this
+is no longer supported by the Linux kernel and instead a real SPI device
+name as listed in one of the tables must be used.
+
+Not having a real SPI device name will lead to an error being printed and
+the spidev driver failing to probe.
+
+Sysfs also supports userspace driven binding/unbinding of drivers to
+devices that do not bind automatically using one of the tables above.
+To make the spidev driver bind to such a device, use the following:
+
+ echo spidev > /sys/bus/spi/devices/spiB.C/driver_override
+ echo spiB.C > /sys/bus/spi/drivers/spidev/bind
+
+When the spidev driver is bound to a SPI device, the sysfs node for the
+device will include a child device node with a "dev" attribute that will
+be understood by udev or mdev (udev replacement from BusyBox; it's less
+featureful, but often enough).

+--------------------
+
+There are two kinds of notifications that secure world can use to make
+normal world aware of some event.
+
+1. Synchronous notifications delivered with ``OPTEE_RPC_CMD_NOTIFICATION``
+ using the ``OPTEE_RPC_NOTIFICATION_SEND`` parameter.

+this is only usable when secure world is entered with a yielding call via
+``OPTEE_SMC_CALL_WITH_ARG``. This excludes such notifications from secure
+world interrupt handlers.
+
+An asynchronous notification is delivered via a non-secure edge-triggered
+interrupt to an interrupt handler registered in the OP-TEE driver. The
+actual notification value are retrieved with the fast call
+``OPTEE_SMC_GET_ASYNC_NOTIF_VALUE``. Note that one interrupt can represent
+multiple notifications.
+
+One notification value ``OPTEE_SMC_ASYNC_NOTIF_VALUE_DO_BOTTOM_HALF`` has a
+special meaning. When this value is received it means that normal world is
+supposed to make a yielding call ``OPTEE_MSG_CMD_DO_BOTTOM_HALF``. This
+call is done from the thread assisting the interrupt handler. This is a

+3. 红黑树

+

+
+4. CFS的一些特å¾
+================
+
+CFS使用纳秒粒度的计时,ä¸ä¾èµ–于任何jiffies或HZ的细节。因此CFSå¹¶ä¸åƒä¹‹å‰çš„调度器那样
+有“时间片â€çš„æ¦‚念,也没有任何å¯å‘å¼çš„设计。唯一å¯è°ƒçš„傿•°ï¼ˆä½ éœ€è¦æ‰“å¼€CONFIG_SCHED_DEBUG)是:

+符åˆé¢„期的行为。
+
+CFS调度器处ç†nice级别和SCHED_BATCH的能力比之å‰çš„原始调度器更强:两ç§ç±»åž‹çš„工作负载

+
+
+
+5. 调度策略
+===========
+
+CFS实现了三ç§è°ƒåº¦ç­–略:
+
+ - SCHED_NORMAL:(传统被称为SCHED_OTHER):该调度策略用于普通任务。
+
+ - SCHED_BATCH:抢å ä¸åƒæ™®é€šä»»åŠ¡é‚£æ ·é¢‘ç¹ï¼Œå› æ­¤å…许任务è¿è¡Œæ›´é•¿æ—¶é—´ï¼Œæ›´å¥½åœ°åˆ©ç”¨ç¼“存,

+
+ - SCHED_IDLE:它比nice 19更弱,ä¸è¿‡å®ƒä¸æ˜¯çœŸæ­£çš„idle定时器调度器,因为è¦é¿å…给机器
+ å¸¦æ¥æ­»é”的优先级å转问题。
+
+SCHED_FIFO/_RR被实现在sched/rt.c中,它们由POSIX具体说明。
+
+util-linux-ng 2.13.1.1中的chrt命令å¯ä»¥è®¾ç½®ä»¥ä¸Šæ‰€æœ‰ç­–略,除了SCHED_IDLE。
+
+
+
+6. 调度类
+=========
+
+æ–°çš„CFSè°ƒåº¦å™¨è¢«è®¾è®¡æˆæ”¯æŒâ€œè°ƒåº¦ç±»â€ï¼Œä¸€ç§è°ƒåº¦æ¨¡å—çš„å¯æ‰©å±•层次结构。这些模å—å°è£…了调度策略
+细节,由调度器核心代ç å¤„ç†ï¼Œä¸”无需对它们åšå¤ªå¤šå‡è®¾ã€‚
+
+sched/fair.c 实现了上文æè¿°çš„CFS调度器。
+
+sched/rt.c 实现了SCHED_FIFOå’ŒSCHED_RR语义,且比之å‰çš„原始调度器更简æ´ã€‚它使用了100个
+è¿è¡Œé˜Ÿåˆ—(总共100个实时优先级,替代了之å‰è°ƒåº¦å™¨çš„140个),且ä¸éœ€è¦è¿‡æœŸæ•°ç»„(expired

+
+调度类由sched_class结构体实现,它包括一些函数钩å­ï¼Œå½“感兴趣的事件å‘生时,钩å­è¢«è°ƒç”¨ã€‚
+
+这是(部分)钩å­çš„列表:
+
+ - enqueue_task(...)

+
+ - yield_task(...)
+
+ 这个函数的行为基本上是出队,紧接ç€å…¥é˜Ÿï¼Œé™¤éžcompat_yield sysctl被开å¯ã€‚åœ¨é‚£ç§æƒ…况下,

+

+ è¿™ä¸ªå‡½æ•°é€‰æ‹©æŽ¥ä¸‹æ¥æœ€é€‚åˆè¿è¡Œçš„任务。
+
+ - set_curr_task(...)
+
+ 这个函数在任务改å˜è°ƒåº¦ç±»æˆ–改å˜ä»»åŠ¡ç»„æ—¶è¢«è°ƒç”¨ã€‚
+
+ - task_tick(...)
+
+ 这个函数最常被时间滴答函数调用,它å¯èƒ½å¯¼è‡´è¿›ç¨‹åˆ‡æ¢ã€‚这驱动了è¿è¡Œæ—¶æŠ¢å ã€‚
+
+
+
+
+7. CFS的组调度扩展
+==================
+
+通常,调度器æ“作粒度为任务,努力为æ¯ä¸ªä»»åŠ¡æä¾›å…¬å¹³çš„CPU时间。有时å¯èƒ½å¸Œæœ›å°†ä»»åŠ¡ç¼–ç»„ï¼Œ

+
+Teletypewriter (TTY) layer takes care of all those serial devices. Including
+the virtual ones like pseudoterminal (PTY).
+
+TTY structures
+==============
+
+There are several major TTY structures. Every TTY device in a system has a
+corresponding struct tty_port. These devices are maintained by a TTY driver
+which is struct tty_driver. This structure describes the driver but also
+contains a reference to operations which could be performed on the TTYs. It is
+struct tty_operations. Then, upon open, a struct tty_struct is allocated and
+lives until the final close. During this time, several callbacks from struct
+tty_operations are invoked by the TTY layer.
+
+Every character received by the kernel (both from devices and users) is passed
+through a preselected :doc:`tty_ldisc` (in
+short ldisc; in C, struct tty_ldisc_ops). Its task is to transform characters
+as defined by a particular ldisc or by user too. The default one is n_tty,
+implementing echoes, signal handling, jobs control, special characters
+processing, and more. The transformed characters are passed further to
+user/device, depending on the source.
+
+In-detail description of the named TTY structures is in separate documents:
+
+.. toctree::
+ :maxdepth: 2
+
+ tty_driver
+ tty_port
+ tty_struct
+ tty_ldisc
+ tty_buffer
+ n_tty
+ tty_internals
+
+Writing TTY Driver
+==================
+
+Before one starts writing a TTY driver, they must consider
+:doc:`Serial <../driver-api/serial/driver>` and :doc:`USB Serial
+<../usb/usb-serial>` layers
+first. Drivers for serial devices can often use one of these specific layers to
+implement a serial driver. Only special devices should be handled directly by
+the TTY Layer. If you are about to write such a driver, read on.
+
+A *typical* sequence a TTY driver performs is as follows:
+
+#. Allocate and register a TTY driver (module init)
+#. Create and register TTY devices as they are probed (probe function)
+#. Handle TTY operations and events like interrupts (TTY core invokes the
+ former, the device the latter)
+#. Remove devices as they are going away (remove function)
+#. Unregister and free the TTY driver (module exit)
+
+Steps regarding driver, i.e. 1., 3., and 5. are described in detail in
+:doc:`tty_driver`. For the other two (devices handling), look into
+:doc:`tty_port`.

+TTY Driver and TTY Operations
+=============================
+
+.. contents:: :local:
+
+Allocation
+==========
+
+The first thing a driver needs to do is to allocate a struct tty_driver. This
+is done by tty_alloc_driver() (or __tty_alloc_driver()). Next, the newly
+allocated structure is filled with information. See `TTY Driver Reference`_ at
+the end of this document on what actually shall be filled in.
+
+The allocation routines expect a number of devices the driver can handle at
+most and flags. Flags are those starting ``TTY_DRIVER_`` listed and described
+in `TTY Driver Flags`_ below.
+
+When the driver is about to be freed, tty_driver_kref_put() is called on that.
+It will decrements the reference count and if it reaches zero, the driver is
+freed.
+
+For reference, both allocation and deallocation functions are explained here in
+detail:
+
+.. kernel-doc:: drivers/tty/tty_io.c
+ :identifiers: __tty_alloc_driver tty_driver_kref_put
+
+TTY Driver Flags
+----------------
+
+Here comes the documentation of flags accepted by tty_alloc_driver() (or
+__tty_alloc_driver()):
+
+.. kernel-doc:: include/linux/tty_driver.h
+ :doc: TTY Driver Flags
+
+----
+
+Registration
+============
+
+When a struct tty_driver is allocated and filled in, it can be registered using
+tty_register_driver(). It is recommended to pass ``TTY_DRIVER_DYNAMIC_DEV`` in
+flags of tty_alloc_driver(). If it is not passed, *all* devices are also
+registered during tty_register_driver() and the following paragraph of
+registering devices can be skipped for such drivers. However, the struct
+tty_port part in `Registering Devices`_ is still relevant there.
+
+.. kernel-doc:: drivers/tty/tty_io.c
+ :identifiers: tty_register_driver tty_unregister_driver
+
+Registering Devices
+-------------------
+
+Every TTY device shall be backed by a struct tty_port. Usually, TTY drivers
+embed tty_port into device's private structures. Further details about handling
+tty_port can be found in :doc:`tty_port`. The driver is also recommended to use
+tty_port's reference counting by tty_port_get() and tty_port_put(). The final
+put is supposed to free the tty_port including the device's private struct.
+
+Unless ``TTY_DRIVER_DYNAMIC_DEV`` was passed as flags to tty_alloc_driver(),
+TTY driver is supposed to register every device discovered in the system
+(the latter is preferred). This is performed by tty_register_device(). Or by
+tty_register_device_attr() if the driver wants to expose some information
+through struct attribute_group. Both of them register ``index``'th device and
+upon return, the device can be opened. There are also preferred tty_port
+variants described in `Linking Devices to Ports`_ later. It is up to driver to
+manage free indices and choosing the right one. The TTY layer only refuses to
+register more devices than passed to tty_alloc_driver().
+
+When the device is opened, the TTY layer allocates struct tty_struct and starts
+calling operations from :c:member:`tty_driver.ops`, see `TTY Operations
+Reference`_.
+
+The registration routines are documented as follows:
+
+.. kernel-doc:: drivers/tty/tty_io.c
+ :identifiers: tty_register_device tty_register_device_attr
+ tty_unregister_device
+
+----
+
+Linking Devices to Ports
+------------------------
+As stated earlier, every TTY device shall have a struct tty_port assigned to
+it. It must be known to the TTY layer at :c:member:`tty_driver.ops.install()`
+at latest. There are few helpers to *link* the two. Ideally, the driver uses
+tty_port_register_device() or tty_port_register_device_attr() instead of
+tty_register_device() and tty_register_device_attr() at the registration time.
+This way, the driver needs not care about linking later on.
+
+If that is not possible, the driver still can link the tty_port to a specific
+index *before* the actual registration by tty_port_link_device(). If it still
+does not fit, tty_port_install() can be used from the
+:c:member:`tty_driver.ops.install` hook as a last resort. The last one is
+dedicated mostly for in-memory devices like PTY where tty_ports are allocated
+on demand.
+
+The linking routines are documented here:

+TTY Line Discipline
+===================
+
+.. contents:: :local:
+
+TTY line discipline process all incoming and outgoing character from/to a tty
+device. The default line discipline is :doc:`N_TTY <n_tty>`. It is also a
+fallback if establishing any other discipline for a tty fails. If even N_TTY
+fails, N_NULL takes over. That never fails, but also does not process any
+characters -- it throws them away.
+
+Registration
+============
+
+Line disciplines are registered with tty_register_ldisc() passing the ldisc
+structure. At the point of registration the discipline must be ready to use and
+it is possible it will get used before the call returns success. If the call
+returns an error then it won’t get called. Do not re-use ldisc numbers as they
+are part of the userspace ABI and writing over an existing ldisc will cause
+demons to eat your computer. You must not re-register over the top of the line
+discipline even with the same data or your computer again will be eaten by
+demons. In order to remove a line discipline call tty_unregister_ldisc().
+
+Heed this warning: the reference count field of the registered copies of the
+tty_ldisc structure in the ldisc table counts the number of lines using this
+discipline. The reference count of the tty_ldisc structure within a tty counts
+the number of active users of the ldisc at this instant. In effect it counts
+the number of threads of execution within an ldisc method (plus those about to
+enter and exit although this detail matters not).

+Line discipline methods can call the methods of the underlying hardware driver.

+=========
+
+Line discipline methods have access to :c:member:`tty_struct.flags` field. See
+:doc:`tty_struct`.
+
+Locking
+=======
+
+Callers to the line discipline functions from the tty layer are required to

+but not yet enforced.

+
+While these functions are slightly slower than the old code they should have
+minimal impact as most receive logic uses the flip buffers and they only
+need to take a reference when they push bits up through the driver.
+
+A caution: The :c:member:`tty_ldisc_ops.open()`,
+:c:member:`tty_ldisc_ops.close()` and :c:member:`tty_driver.set_ldisc()`
+functions are called with the ldisc unavailable. Thus tty_ldisc_ref() will fail
+in this situation if used within these functions. Ldisc and driver code
+calling its own functions must be careful in this case.

+ * Notes on power-, reset- and nmi- button and control:
+ * - The -button signals can be used to monitor physical buttons.
+ * - The -control signals can be used to actuate the specific
+ * operation.
+ * - In hardware, the -button signals are connected to the -control
+ * signals through drivers with the -control signals being

- The debug board is an integral part of the MXC 3-stack(PDK)
- platforms, it can be attached or removed from the peripheral
- board. On debug board, several debug devices(ethernet, UART,

- * scan-log-data driver for PPC64 Todd Inglett <tinglett@vnet.ibm.com>
- *
- * When ppc64 hardware fails the service processor dumps internal state
- * of the system. After a reboot the operating system can access a dump
- * of this data using this driver. A dump exists if the device-tree
- * /chosen/ibm,scan-log-data property exists.
- *
- * This driver exports /proc/powerpc/scan-log-dump which can be read.
- * The driver supports only sequential reads.
- *
- * The driver looks at a write to the driver for the single word "reset".
- * If given, the driver will reset the scanlog so the platform can free it.

+ * upper and lower halves and is removed from mm_context_t::pgtable_list.
+ *
+ * When 2KB-pgtable is freed from to fully allocated parent page that
+ * page turns partially allocated and added to mm_context_t::pgtable_list.
+ *
+ * If 2KB-pgtable is freed from the partially allocated parent page that
+ * page turns unused and gets removed from mm_context_t::pgtable_list.
+ * Furthermore, the unused parent page is released.
+ *
+ * As follows from the above, no unallocated or fully allocated parent
+ * pages are contained in mm_context_t::pgtable_list.
+ *
+ * The upper byte (bits 24-31) of the parent page _refcount is used
+ * for tracking contained 2KB-pgtables and has the following format:
+ *
+ * PP AA
+ * 01234567 upper byte (bits 24-31) of struct page::_refcount
+ * || ||
+ * || |+--- upper 2KB-pgtable is allocated
+ * || +---- lower 2KB-pgtable is allocated
+ * |+------- upper 2KB-pgtable is pending for removal
+ * +-------- lower 2KB-pgtable is pending for removal
+ *
+ * (See commit 620b4e903179 ("s390: use _refcount for pgtables") on why
+ * using _refcount is possible).
+ *
+ * When 2KB-pgtable is allocated the corresponding AA bit is set to 1.
+ * The parent page is either:
+ * - added to mm_context_t::pgtable_list in case the second half of the
+ * parent page is still unallocated;
+ * - removed from mm_context_t::pgtable_list in case both hales of the
+ * parent page are allocated;
+ * These operations are protected with mm_context_t::lock.
+ *
+ * When 2KB-pgtable is deallocated the corresponding AA bit is set to 0
+ * and the corresponding PP bit is set to 1 in a single atomic operation.
+ * Thus, PP and AA bits corresponding to the same 2KB-pgtable are mutually
+ * exclusive and may never be both set to 1!
+ * The parent page is either:
+ * - added to mm_context_t::pgtable_list in case the second half of the
+ * parent page is still allocated;
+ * - removed from mm_context_t::pgtable_list in case the second half of
+ * the parent page is unallocated;
+ * These operations are protected with mm_context_t::lock.
+ *
+ * It is important to understand that mm_context_t::lock only protects
+ * mm_context_t::pgtable_list and AA bits, but not the parent page itself
+ * and PP bits.
+ *
+ * Releasing the parent page happens whenever the PP bit turns from 1 to 0,
+ * while both AA bits and the second PP bit are already unset. Then the
+ * parent page does not contain any 2KB-pgtable fragment anymore, and it has
+ * also been removed from mm_context_t::pgtable_list. It is safe to release
+ * the page therefore.
+ *
+ * PGSTE memory spaces use full 4KB-pgtables and do not need most of the
+ * logic described above. Both AA bits are set to 1 to denote a 4KB-pgtable
+ * while the PP bits are never used, nor such a page is added to or removed
+ * from mm_context_t::pgtable_list.

- * of its woken bfq_queues. The rationale behind this
- * additional condition is as follows:
- * - consider a bfq_queue, say Q1, detected as a waker of
- * another bfq_queue, say Q2
- * - by definition of a waker, Q1 blocks the I/O of Q2, i.e.,
- * some I/O of Q1 needs to be completed for new I/O of Q2
- * to arrive. A notable example of waker is journald
- * - so, Q1 and Q2 are in any respect the queues of two
- * cooperating processes (or of two cooperating sets of
- * processes): the goal of Q1's I/O is doing what needs to
- * be done so that new Q2's I/O can finally be
- * issued. Therefore, if the service of Q1's I/O is delayed,
- * then Q2's I/O is delayed too. Conversely, if Q2's I/O is
- * delayed, the goal of Q1's I/O is hindered.
- * - as a consequence, if some I/O of Q1/Q2 arrives while
- * Q2/Q1 is the only queue in service, there is absolutely
- * no point in delaying the service of such an I/O. The
- * only possible result is a throughput loss
- * - so, when the above condition holds, the best option is to
- * have the new I/O dispatched as soon as possible
- * - the most effective and efficient way to attain the above
- * goal is to put the new I/O directly in the dispatch
- * list
- * - as an additional restriction, Q1 and Q2 must be the only
- * busy queues for this commit to put the I/O of Q2/Q1 in
- * the dispatch list. This is necessary, because, if also
- * other queues are waiting for service, then putting new
- * I/O directly in the dispatch list may evidently cause a

+/**
+ * DOC: PURPOSE
+ *
+ * In some subsystems, the functionality of the core device (PCI/ACPI/other) is
+ * too complex for a single device to be managed by a monolithic driver (e.g.
+ * Sound Open Firmware), multiple devices might implement a common intersection
+ * of functionality (e.g. NICs + RDMA), or a driver may want to export an
+ * interface for another subsystem to drive (e.g. SIOV Physical Function export
+ * Virtual Function management). A split of the functionality into child-
+ * devices representing sub-domains of functionality makes it possible to
+ * compartmentalize, layer, and distribute domain-specific concerns via a Linux
+ * device-driver model.
+ *
+ * An example for this kind of requirement is the audio subsystem where a
+ * single IP is handling multiple entities such as HDMI, Soundwire, local
+ * devices such as mics/speakers etc. The split for the core's functionality
+ * can be arbitrary or be defined by the DSP firmware topology and include
+ * hooks for test/debug. This allows for the audio core device to be minimal
+ * and focused on hardware-specific control and communication.
+ *
+ * Each auxiliary_device represents a part of its parent functionality. The
+ * generic behavior can be extended and specialized as needed by encapsulating
+ * an auxiliary_device within other domain-specific structures and the use of
+ * .ops callbacks. Devices on the auxiliary bus do not share any structures and
+ * the use of a communication channel with the parent is domain-specific.
+ *
+ * Note that ops are intended as a way to augment instance behavior within a
+ * class of auxiliary devices, it is not the mechanism for exporting common
+ * infrastructure from the parent. Consider EXPORT_SYMBOL_NS() to convey
+ * infrastructure from the parent module to the auxiliary module(s).
+ */
+
+/**
+ * DOC: USAGE
+ *
+ * The auxiliary bus is to be used when a driver and one or more kernel
+ * modules, who share a common header file with the driver, need a mechanism to
+ * connect and provide access to a shared object allocated by the
+ * auxiliary_device's registering driver. The registering driver for the
+ * auxiliary_device(s) and the kernel module(s) registering auxiliary_drivers
+ * can be from the same subsystem, or from multiple subsystems.
+ *
+ * The emphasis here is on a common generic interface that keeps subsystem
+ * customization out of the bus infrastructure.
+ *
+ * One example is a PCI network device that is RDMA-capable and exports a child
+ * device to be driven by an auxiliary_driver in the RDMA subsystem. The PCI
+ * driver allocates and registers an auxiliary_device for each physical
+ * function on the NIC. The RDMA driver registers an auxiliary_driver that
+ * claims each of these auxiliary_devices. This conveys data/ops published by
+ * the parent PCI device/driver to the RDMA auxiliary_driver.
+ *
+ * Another use case is for the PCI device to be split out into multiple sub
+ * functions. For each sub function an auxiliary_device is created. A PCI sub
+ * function driver binds to such devices that creates its own one or more class
+ * devices. A PCI sub function auxiliary device is likely to be contained in a
+ * struct with additional attributes such as user defined sub function number
+ * and optional attributes such as resources and a link to the parent device.
+ * These attributes could be used by systemd/udev; and hence should be
+ * initialized before a driver binds to an auxiliary_device.
+ *
+ * A key requirement for utilizing the auxiliary bus is that there is no
+ * dependency on a physical bus, device, register accesses or regmap support.
+ * These individual devices split from the core cannot live on the platform bus
+ * as they are not physical devices that are controlled by DT/ACPI. The same
+ * argument applies for not using MFD in this scenario as MFD relies on
+ * individual function devices being physical devices.
+ */
+
+/**
+ * DOC: EXAMPLE
+ *
+ * Auxiliary devices are created and registered by a subsystem-level core
+ * device that needs to break up its functionality into smaller fragments. One
+ * way to extend the scope of an auxiliary_device is to encapsulate it within a
+ * domain- pecific structure defined by the parent device. This structure
+ * contains the auxiliary_device and any associated shared data/callbacks
+ * needed to establish the connection with the parent.
+ *
+ * An example is:
+ *
+ * .. code-block:: c
+ *
+ * struct foo {
+ * struct auxiliary_device auxdev;
+ * void (*connect)(struct auxiliary_device *auxdev);
+ * void (*disconnect)(struct auxiliary_device *auxdev);
+ * void *data;
+ * };
+ *
+ * The parent device then registers the auxiliary_device by calling
+ * auxiliary_device_init(), and then auxiliary_device_add(), with the pointer
+ * to the auxdev member of the above structure. The parent provides a name for
+ * the auxiliary_device that, combined with the parent's KBUILD_MODNAME,
+ * creates a match_name that is be used for matching and binding with a driver.
+ *
+ * Whenever an auxiliary_driver is registered, based on the match_name, the
+ * auxiliary_driver's probe() is invoked for the matching devices. The
+ * auxiliary_driver can also be encapsulated inside custom drivers that make
+ * the core device's functionality extensible by adding additional
+ * domain-specific ops as follows:
+ *
+ * .. code-block:: c
+ *
+ * struct my_ops {
+ * void (*send)(struct auxiliary_device *auxdev);
+ * void (*receive)(struct auxiliary_device *auxdev);
+ * };
+ *
+ *
+ * struct my_driver {
+ * struct auxiliary_driver auxiliary_drv;
+ * const struct my_ops ops;
+ * };
+ *
+ * An example of this type of usage is:
+ *
+ * .. code-block:: c
+ *
+ * const struct auxiliary_device_id my_auxiliary_id_table[] = {
+ * { .name = "foo_mod.foo_dev" },
+ * { },
+ * };
+ *
+ * const struct my_ops my_custom_ops = {
+ * .send = my_tx,
+ * .receive = my_rx,
+ * };
+ *
+ * const struct my_driver my_drv = {
+ * .auxiliary_drv = {
+ * .name = "myauxiliarydrv",
+ * .id_table = my_auxiliary_id_table,
+ * .probe = my_probe,
+ * .remove = my_remove,
+ * .shutdown = my_shutdown,
+ * },
+ * .ops = my_custom_ops,
+ * };
+ */

+ * Message Origin (Should always be 1)
+ * A legacy out-of-tree QAT driver allowed for a set of messages not supported
+ * by this driver; these had a Msg Origin of 0 and are ignored by this driver.
+ *
+ * When a PF or VF attempts to send a message in the lower or upper 16 bits,
+ * respectively, the other 16 bits are written to first with a defined
+ * IN_USE_BY pattern as part of a collision control scheme (see function
+ * adf_gen2_pfvf_send() in adf_pf2vf_msg.c).
+ *
+ *
+ * PF<->VF Gen4 Messaging format
+ *
+ * Similarly to the gen2 messaging format, 32-bit long registers are used for
+ * communication between PF and VFs. However, each VF and PF share a pair of
+ * 32-bits register to avoid collisions: one for PV to VF messages and one
+ * for VF to PF messages.
+ *
+ * Both the Interrupt bit and the Message Origin bit retain the same position
+ * and meaning, although non-system messages are now deprecated and not
+ * expected.

+ * "privacy-screen sw-state" can be set to change the privacy-screen state

+ * In this case the driver must update both the hw-state and the sw-state
+ * to reflect the new value, overwriting any pending state requests in the
+ * sw-state. Any pending sw-state requests are thus discarded.
+ *
+ * Note that the ability for the state to change outside of control of

+ * Driver for the LetSketch / VSON WP9620N drawing tablet.
+ * This drawing tablet is also sold under other brand names such as Case U,
+ * presumably this driver will work for all of them. But it has only been
+ * tested with a LetSketch WP9620N model.
+ *
+ * These tablets also work without a special HID driver, but then only part
+ * of the active area works and both the pad and stylus buttons are hardwired
+ * to special key-combos. E.g. the 2 stylus buttons send right mouse clicks /
+ * resp. "e" key presses.
+ *
+ * This device has 4 USB interfaces:
+ *
+ * Interface 0 EP 0x81 bootclass mouse, rdesc len 18, report id 0x08,
+ * Application(ff00.0001)
+ * This interface sends raw event input reports in a custom format, but only
+ * after doing the special dance from letsketch_probe(). After enabling this
+ * interface the other 3 interfaces are disabled.
+ *
+ * Interface 1 EP 0x82 bootclass mouse, rdesc len 83, report id 0x0a, Tablet
+ * This interface sends absolute events for the pen, including pressure,
+ * but only for some part of the active area due to special "aspect ratio"
+ * correction and only half by default since it assumes it will be used
+ * with a phone in portraid mode, while using the tablet in landscape mode.
+ * Also stylus + pad button events are not reported here.
+ *
+ * Interface 2 EP 0x83 bootclass keybd, rdesc len 64, report id none, Std Kbd
+ * This interfaces send various hard-coded key-combos for the pad buttons
+ * and "e" keypresses for the 2nd stylus button
+ *
+ * Interface 3 EP 0x84 bootclass mouse, rdesc len 75, report id 0x01, Std Mouse
+ * This reports right-click mouse-button events for the 1st stylus button

+ * This driver uses a fixed calibration value in order to scale current/power
+ * based on a fixed shunt resistor value. This allows for conversion within the
+ * device to avoid integer limits whilst current/power accuracy is scaled
+ * relative to the shunt resistor value within the driver. This is similar to
+ * how the ina2xx driver handles current/power scaling.
+ *
+ * The end result of this is that increasing shunt values (from a fixed 20 mOhm
+ * shunt) increase the effective current/power accuracy whilst limiting the
+ * range and decreasing shunt values decrease the effective accuracy but
+ * increase the range.
+ *
+ * The value of the Current register is calculated given the following:
+ * Current (A) = (shunt voltage register * 5) * calibration / 81920
+ *
+ * The maximum shunt voltage is 163.835 mV (0x7fff, ADC_RANGE = 0, gain = 4).
+ * With the maximum current value of 0x7fff and a fixed shunt value results in
+ * a calibration value of 16384 (0x4000).
+ *
+ * 0x7fff = (0x7fff * 5) * calibration / 81920
+ * calibration = 0x4000
+ *
+ * Equivalent calibration is applied for the Power register (maximum value for
+ * bus voltage is 102396.875 mV, 0x7fff), where the maximum power that can
+ * occur is ~16776192 uW (register value 0x147a8):
+ *
+ * This scaling means the resulting values for Current and Power registers need
+ * to be scaled by the difference between the fixed shunt resistor and the
+ * actual shunt resistor:
+ *
+ * shunt = 0x4000 / (819.2 * 10^6) / 0.001 = 20000 uOhms (with 1mA/lsb)
+ *
+ * Current (mA) = register value * 20000 / rshunt / 4 * gain
+ * Power (W) = 0.2 * register value * 20000 / rshunt / 4 * gain

+ * isn't necessarily called a "sector" by the vendor.
+ * @n_sectors: the number of sectors.

+ * @parse_sfdp: true when flash supports SFDP tables. The false value has no

+ * instead use the SPI_NOR_SKIP_SFDP sfdp_flag.
+ * @flags: flags that indicate support that is not defined by the
+ * JESD216 standard in its SFDP tables. Flag meanings:
+ * SPI_NOR_HAS_LOCK: flash supports lock/unlock via SR
+ * SPI_NOR_HAS_TB: flash SR has Top/Bottom (TB) protect bit. Must be
+ * used with SPI_NOR_HAS_LOCK.
+ * SPI_NOR_TB_SR_BIT6: Top/Bottom (TB) is bit 6 of status register.
+ * Must be used with SPI_NOR_HAS_TB.
+ * SPI_NOR_4BIT_BP: flash SR has 4 bit fields (BP0-3) for block
+ * protection.
+ * SPI_NOR_BP3_SR_BIT6: BP3 is bit 6 of status register. Must be used with
+ * SPI_NOR_4BIT_BP.
+ * SPI_NOR_SWP_IS_VOLATILE: flash has volatile software write protection bits.
+ * Usually these will power-up in a write-protected
+ * state.
+ * SPI_NOR_NO_ERASE: no erase command needed.
+ * NO_CHIP_ERASE: chip does not support chip erase.
+ * SPI_NOR_NO_FR: can't do fastread.
+ * USE_CLSR: use CLSR command.
+ * USE_FSR: use flag status register
+ * SPI_NOR_XSR_RDY: S3AN flashes have specific opcode to read the
+ * status register.
+ *
+ * @no_sfdp_flags: flags that indicate support that can be discovered via SFDP.
+ * Used when SFDP tables are not defined in the flash. These
+ * flags are used together with the SPI_NOR_SKIP_SFDP flag.
+ * SPI_NOR_SKIP_SFDP: skip parsing of SFDP tables.
+ * SECT_4K: SPINOR_OP_BE_4K works uniformly.
+ * SECT_4K_PMC: SPINOR_OP_BE_4K_PMC works uniformly.
+ * SPI_NOR_DUAL_READ: flash supports Dual Read.
+ * SPI_NOR_QUAD_READ: flash supports Quad Read.
+ * SPI_NOR_OCTAL_READ: flash supports Octal Read.
+ * SPI_NOR_OCTAL_DTR_READ: flash supports octal DTR Read.
+ * SPI_NOR_OCTAL_DTR_PP: flash supports Octal DTR Page Program.
+ *
+ * @fixup_flags: flags that indicate support that can be discovered via SFDP
+ * ideally, but can not be discovered for this particular flash
+ * because the SFDP table that indicates this support is not
+ * defined by the flash. In case the table for this support is
+ * defined but has wrong values, one should instead use a
+ * post_sfdp() hook to set the SNOR_F equivalent flag.
+ *
+ * SPI_NOR_4B_OPCODES: use dedicated 4byte address op codes to support
+ * memory size above 128Mib.
+ * SPI_NOR_IO_MODE_EN_VOLATILE: flash enables the best available I/O mode
+ * via a volatile bit.
+ * @mfr_flags: manufacturer private flags. Used in the manufacturer fixup
+ * hooks to differentiate support between flashes of the same
+ * manufacturer.
+ * @otp_org: flash's OTP organization.
