+You can also pass arguments to the kernel by setting FDARGS in

+arch/x86/boot/Makefile.
-Hence you want to set bits 0 to 13 as 0, meaning that your RAM disk

+GPIO Testing Driver
+===================
+
+The GPIO Testing Driver (gpio-mockup) provides a way to create simulated GPIO
+chips for testing purposes. The lines exposed by these chips can be accessed
+using the standard GPIO character device interface as well as manipulated
+using the dedicated debugfs directory structure.
+
+Creating simulated chips using module params
+--------------------------------------------
+
+When loading the gpio-mockup driver a number of parameters can be passed to the
+module.
+
+ gpio_mockup_ranges
+
+ This parameter takes an argument in the form of an array of integer
+ pairs. Each pair defines the base GPIO number (if any) and the number
+ of lines exposed by the chip. If the base GPIO is -1, the gpiolib
+ will assign it automatically.
+
+ Example: gpio_mockup_ranges=-1,8,-1,16,405,4
+
+ The line above creates three chips. The first one will expose 8 lines,
+ the second 16 and the third 4. The base GPIO for the third chip is set
+ to 405 while for two first chips it will be assigned automatically.
+
+ gpio_named_lines
+
+ This parameter doesn't take any arguments. It lets the driver know that
+ GPIO lines exposed by it should be named.
+
+ The name format is: gpio-mockup-X-Y where X is mockup chip's ID
+ and Y is the line offset.
+
+Manipulating simulated lines
+----------------------------
+
+Each mockup chip creates its own subdirectory in /sys/kernel/debug/gpio-mockup/.
+The directory is named after the chip's label. A symlink is also created, named
+after the chip's name, which points to the label directory.
+
+Inside each subdirectory, there's a separate attribute for each GPIO line. The
+name of the attribute represents the line's offset in the chip.
+
+Reading from a line attribute returns the current value. Writing to it (0 or 1)
+changes the configuration of the simulated pull-up/pull-down resistor
+(1 - pull-up, 0 - pull-down).

+Rockchip Image Signal Processor (rkisp1)
+=========================================
+
+Introduction
+============
+
+This file documents the driver for the Rockchip ISP1 that is part of RK3288
+and RK3399 SoCs. The driver is located under drivers/staging/media/rkisp1
+and uses the Media-Controller API.
+
+Topology
+========
+.. _rkisp1_topology_graph:
+
+.. kernel-figure:: rkisp1.dot
+ :alt: Diagram of the default media pipeline topology
+ :align: center
+
+
+The driver has 4 video devices:
+
+- rkisp1_mainpath: capture device for retrieving images, usually in higher
+ resolution.
+- rkisp1_selfpath: capture device for retrieving images.
+- rkisp1_stats: a metadata capture device that sends statistics.
+- rkisp1_params: a metadata output device that receives parameters
+ configurations from userspace.
+
+The driver has 3 subdevices:
+
+- rkisp1_resizer_mainpath: used to resize and downsample frames for the
+ mainpath capture device.
+- rkisp1_resizer_selfpath: used to resize and downsample frames for the
+ selfpath capture device.
+- rkisp1_isp: is connected to the sensor and is responsible for all the isp
+ operations.
+
+
+rkisp1_mainpath, rkisp1_selfpath - Frames Capture Video Nodes
+-------------------------------------------------------------
+Those are the `mainpath` and `selfpath` capture devices to capture frames.
+Those entities are the DMA engines that write the frames to memory.
+The selfpath video device can capture YUV/RGB formats. Its input is YUV encoded
+stream and it is able to convert it to RGB. The selfpath is not able to
+capture bayer formats.
+The mainpath can capture both bayer and YUV formats but it is not able to
+capture RGB formats.
+Both capture videos support
+the ``V4L2_CAP_IO_MC`` :ref:`capability <device-capabilities>`.
+
+
+rkisp1_resizer_mainpath, rkisp1_resizer_selfpath - Resizers Subdevices Nodes
+----------------------------------------------------------------------------
+Those are resizer entities for the mainpath and the selfpath. Those entities
+can scale the frames up and down and also change the YUV sampling (for example
+YUV4:2:2 -> YUV4:2:0). They also have cropping capability on the sink pad.
+The resizers entities can only operate on YUV:4:2:2 format
+(MEDIA_BUS_FMT_YUYV8_2X8).
+The mainpath capture device supports capturing video in bayer formats. In that
+case the resizer of the mainpath is set to 'bypass' mode - it just forward the
+frame without operating on it.
+
+rkisp1_isp - Image Signal Processing Subdevice Node
+---------------------------------------------------
+This is the isp entity. It is connected to the sensor on sink pad 0 and
+receives the frames using the CSI-2 protocol. It is responsible of configuring
+the CSI-2 protocol. It has a cropping capability on sink pad 0 that is
+connected to the sensor and on source pad 2 connected to the resizer entities.
+Cropping on sink pad 0 defines the image region from the sensor.
+Cropping on source pad 2 defines the region for the Image Stabilizer (IS).
+
+.. _rkisp1_stats:
+
+rkisp1_stats - Statistics Video Node
+------------------------------------
+The statistics video node outputs the 3A (auto focus, auto exposure and auto
+white balance) statistics, and also histogram statistics for the frames that
+are being processed by the rkisp1 to userspace applications.
+Using these data, applications can implement algorithms and re-parameterize
+the driver through the rkisp_params node to improve image quality during a
+video stream.
+The buffer format is defined by struct :c:type:`rkisp1_stat_buffer`, and
+userspace should set
+:ref:`V4L2_META_FMT_RK_ISP1_STAT_3A <v4l2-meta-fmt-stat-rkisp1>` as the
+dataformat.
+
+.. _rkisp1_params:
+
+rkisp1_params - Parameters Video Node
+-------------------------------------
+The rkisp1_params video node receives a set of parameters from userspace
+to be applied to the hardware during a video stream, allowing userspace
+to dynamically modify values such as black level, cross talk corrections
+and others.
+
+The buffer format is defined by struct :c:type:`rkisp1_params_cfg`, and
+userspace should set
+:ref:`V4L2_META_FMT_RK_ISP1_PARAMS <v4l2-meta-fmt-params-rkisp1>` as the
+dataformat.
+
+
+Capturing Video Frames Example
+==============================
+
+In the following example, the sensor connected to pad 0 of 'rkisp1_isp' is
+imx219.
+
+The following commands can be used to capture video from the selfpath video
+node with dimension 900x800 planar format YUV 4:2:2. It uses all cropping
+capabilities possible, (see explanation right below)
+
+.. code-block:: bash
+
+ # set the links
+ "media-ctl" "-d" "platform:rkisp1" "-r"
+ "media-ctl" "-d" "platform:rkisp1" "-l" "'imx219 4-0010':0 -> 'rkisp1_isp':0 [1]"
+ "media-ctl" "-d" "platform:rkisp1" "-l" "'rkisp1_isp':2 -> 'rkisp1_resizer_selfpath':0 [1]"
+ "media-ctl" "-d" "platform:rkisp1" "-l" "'rkisp1_isp':2 -> 'rkisp1_resizer_mainpath':0 [0]"
+
+ # set format for imx219 4-0010:0
+ "media-ctl" "-d" "platform:rkisp1" "--set-v4l2" '"imx219 4-0010":0 [fmt:SRGGB10_1X10/1640x1232]'
+
+ # set format for rkisp1_isp pads:
+ "media-ctl" "-d" "platform:rkisp1" "--set-v4l2" '"rkisp1_isp":0 [fmt:SRGGB10_1X10/1640x1232 crop: (0,0)/1600x1200]'
+ "media-ctl" "-d" "platform:rkisp1" "--set-v4l2" '"rkisp1_isp":2 [fmt:YUYV8_2X8/1600x1200 crop: (0,0)/1500x1100]'
+
+ # set format for rkisp1_resizer_selfpath pads:
+ "media-ctl" "-d" "platform:rkisp1" "--set-v4l2" '"rkisp1_resizer_selfpath":0 [fmt:YUYV8_2X8/1500x1100 crop: (300,400)/1400x1000]'
+ "media-ctl" "-d" "platform:rkisp1" "--set-v4l2" '"rkisp1_resizer_selfpath":1 [fmt:YUYV8_2X8/900x800]'
+
+ # set format for rkisp1_selfpath:
+ "v4l2-ctl" "-z" "platform:rkisp1" "-d" "rkisp1_selfpath" "-v" "width=900,height=800,"
+ "v4l2-ctl" "-z" "platform:rkisp1" "-d" "rkisp1_selfpath" "-v" "pixelformat=422P"
+
+ # start streaming:
+ v4l2-ctl "-z" "platform:rkisp1" "-d" "rkisp1_selfpath" "--stream-mmap" "--stream-count" "10"
+
+
+In the above example the sensor is configured to bayer format:
+`SRGGB10_1X10/1640x1232`. The rkisp1_isp:0 pad should be configured to the
+same mbus format and dimensions as the sensor, otherwise streaming will fail
+with 'EPIPE' error. So it is also configured to `SRGGB10_1X10/1640x1232`.
+In addition, the rkisp1_isp:0 pad is configured to cropping `(0,0)/1600x1200`.
+
+The cropping dimensions are automatically propagated to be the format of the
+isp source pad `rkisp1_isp:2`. Another cropping operation is configured on
+the isp source pad: `(0,0)/1500x1100`.
+
+The resizer's sink pad `rkisp1_resizer_selfpath` should be configured to format
+`YUYV8_2X8/1500x1100` in order to match the format on the other side of the
+link. In addition a cropping `(300,400)/1400x1000` is configured on it.
+
+The source pad of the resizer, `rkisp1_resizer_selfpath:1` is configured to
+format `YUYV8_2X8/900x800`. That means that the resizer first crop a window
+of `(300,400)/1400x100` from the received frame and then scales this window
+to dimension `900x800`.
+
+Note that the above example does not uses the stats-params control loop.
+Therefore the capture frames will not go through the 3A algorithms and
+probably won't have a good quality, and can even look dark and greenish.
+
+Configuring Quantization
+========================
+
+The driver supports limited and full range quantization on YUV formats,
+where limited is the default.
+To switch between one or the other, userspace should use the Colorspace
+Conversion API (CSC) for subdevices on source pad 2 of the
+isp (`rkisp1_isp:2`). The quantization configured on this pad is the
+quantization of the captured video frames on the mainpath and selfpath
+video nodes.
+Note that the resizer and capture entities will always report
+``V4L2_QUANTIZATION_DEFAULT`` even if the quantization is configured to full
+range on `rkisp1_isp:2`. So in order to get the configured quantization,
+application should get it from pad `rkisp1_isp:2`.

-===================
-NFS Fault Injection
-===================
-
-Fault injection is a method for forcing errors that may not normally occur, or
-may be difficult to reproduce. Forcing these errors in a controlled environment
-can help the developer find and fix bugs before their code is shipped in a
-production system. Injecting an error on the Linux NFS server will allow us to
-observe how the client reacts and if it manages to recover its state correctly.
-
-NFSD_FAULT_INJECTION must be selected when configuring the kernel to use this
-feature.
-
-
-Using Fault Injection
-=====================
-On the client, mount the fault injection server through NFS v4.0+ and do some
-work over NFS (open files, take locks, ...).
-
-On the server, mount the debugfs filesystem to <debug_dir> and ls
-<debug_dir>/nfsd. This will show a list of files that will be used for
-injecting faults on the NFS server. As root, write a number n to the file
-corresponding to the action you want the server to take. The server will then
-process the first n items it finds. So if you want to forget 5 locks, echo '5'
-to <debug_dir>/nfsd/forget_locks. A value of 0 will tell the server to forget
-all corresponding items. A log message will be created containing the number
-of items forgotten (check dmesg).
-
-Go back to work on the client and check if the client recovered from the error
-correctly.
-
-
-Available Faults
-================
-forget_clients:
- The NFS server keeps a list of clients that have placed a mount call. If
- this list is cleared, the server will have no knowledge of who the client
- is, forcing the client to reauthenticate with the server.
-
-forget_openowners:
- The NFS server keeps a list of what files are currently opened and who
- they were opened by. Clearing this list will force the client to reopen
- its files.
-
-forget_locks:
- The NFS server keeps a list of what files are currently locked in the VFS.
- Clearing this list will force the client to reclaim its locks (files are
- unlocked through the VFS as they are cleared from this list).
-
-forget_delegations:
- A delegation is used to assure the client that a file, or part of a file,
- has not changed since the delegation was awarded. Clearing this list will
- force the client to reacquire its delegation before accessing the file
- again.
-
-recall_delegations:
- Delegations can be recalled by the server when another client attempts to
- access a file. This test will notify the client that its delegation has
- been revoked, forcing the client to reacquire the delegation before using
- the file again.
-
-
-tools/nfs/inject_faults.sh script
-=================================
-This script has been created to ease the fault injection process. This script
-will detect the mounted debugfs directory and write to the files located there
-based on the arguments passed by the user. For example, running
-`inject_faults.sh forget_locks 1` as root will instruct the server to forget
-one lock. Running `inject_faults forget_locks` will instruct the server to
-forgetall locks.

+=============================
+Arm Coherent Mesh Network PMU
+=============================
+
+CMN-600 is a configurable mesh interconnect consisting of a rectangular
+grid of crosspoints (XPs), with each crosspoint supporting up to two
+device ports to which various AMBA CHI agents are attached.
+
+CMN implements a distributed PMU design as part of its debug and trace
+functionality. This consists of a local monitor (DTM) at every XP, which
+counts up to 4 event signals from the connected device nodes and/or the
+XP itself. Overflow from these local counters is accumulated in up to 8
+global counters implemented by the main controller (DTC), which provides
+overall PMU control and interrupts for global counter overflow.
+
+PMU events
+----------
+
+The PMU driver registers a single PMU device for the whole interconnect,
+see /sys/bus/event_source/devices/arm_cmn. Multi-chip systems may link
+more than one CMN together via external CCIX links - in this situation,
+each mesh counts its own events entirely independently, and additional
+PMU devices will be named arm_cmn_{1..n}.
+
+Most events are specified in a format based directly on the TRM
+definitions - "type" selects the respective node type, and "eventid" the
+event number. Some events require an additional occupancy ID, which is
+specified by "occupid".
+
+* Since RN-D nodes do not have any distinct events from RN-I nodes, they
+ are treated as the same type (0xa), and the common event templates are
+ named "rnid_*".
+
+* The cycle counter is treated as a synthetic event belonging to the DTC
+ node ("type" == 0x3, "eventid" is ignored).
+
+* XP events also encode the port and channel in the "eventid" field, to
+ match the underlying pmu_event0_id encoding for the pmu_event_sel
+ register. The event templates are named with prefixes to cover all
+ permutations.
+
+By default each event provides an aggregate count over all nodes of the
+given type. To target a specific node, "bynodeid" must be set to 1 and
+"nodeid" to the appropriate value derived from the CMN configuration
+(as defined in the "Node ID Mapping" section of the TRM).
+
+Watchpoints
+-----------
+
+The PMU can also count watchpoint events to monitor specific flit
+traffic. Watchpoints are treated as a synthetic event type, and like PMU
+events can be global or targeted with a particular XP's "nodeid" value.
+Since the watchpoint direction is otherwise implicit in the underlying
+register selection, separate events are provided for flit uploads and
+downloads.
+
+The flit match value and mask are passed in config1 and config2 ("val"
+and "mask" respectively). "wp_dev_sel", "wp_chn_sel", "wp_grp" and
+"wp_exclusive" are specified per the TRM definitions for dtm_wp_config0.
+Where a watchpoint needs to match fields from both match groups on the
+REQ or SNP channel, it can be specified as two events - one for each
+group - with the same nonzero "combine" value. The count for such a
+pair of combined events will be attributed to the primary match.
+Watchpoint events with a "combine" value of 0 are considered independent
+and will count individually.

+Memory Tagging Extension (MTE) in AArch64 Linux
+===============================================
+
+Authors: Vincenzo Frascino <vincenzo.frascino@arm.com>
+ Catalin Marinas <catalin.marinas@arm.com>
+
+Date: 2020-02-25
+
+This document describes the provision of the Memory Tagging Extension
+functionality in AArch64 Linux.
+
+Introduction
+============
+
+ARMv8.5 based processors introduce the Memory Tagging Extension (MTE)
+feature. MTE is built on top of the ARMv8.0 virtual address tagging TBI
+(Top Byte Ignore) feature and allows software to access a 4-bit
+allocation tag for each 16-byte granule in the physical address space.
+Such memory range must be mapped with the Normal-Tagged memory
+attribute. A logical tag is derived from bits 59-56 of the virtual
+address used for the memory access. A CPU with MTE enabled will compare
+the logical tag against the allocation tag and potentially raise an
+exception on mismatch, subject to system registers configuration.
+
+Userspace Support
+=================
+
+When ``CONFIG_ARM64_MTE`` is selected and Memory Tagging Extension is
+supported by the hardware, the kernel advertises the feature to
+userspace via ``HWCAP2_MTE``.
+
+PROT_MTE
+--------
+
+To access the allocation tags, a user process must enable the Tagged
+memory attribute on an address range using a new ``prot`` flag for
+``mmap()`` and ``mprotect()``:
+
+``PROT_MTE`` - Pages allow access to the MTE allocation tags.
+
+The allocation tag is set to 0 when such pages are first mapped in the
+user address space and preserved on copy-on-write. ``MAP_SHARED`` is
+supported and the allocation tags can be shared between processes.
+
+**Note**: ``PROT_MTE`` is only supported on ``MAP_ANONYMOUS`` and
+RAM-based file mappings (``tmpfs``, ``memfd``). Passing it to other
+types of mapping will result in ``-EINVAL`` returned by these system
+calls.
+
+**Note**: The ``PROT_MTE`` flag (and corresponding memory type) cannot
+be cleared by ``mprotect()``.
+
+**Note**: ``madvise()`` memory ranges with ``MADV_DONTNEED`` and
+``MADV_FREE`` may have the allocation tags cleared (set to 0) at any
+point after the system call.
+
+Tag Check Faults
+----------------
+
+When ``PROT_MTE`` is enabled on an address range and a mismatch between
+the logical and allocation tags occurs on access, there are three
+configurable behaviours:
+
+- *Ignore* - This is the default mode. The CPU (and kernel) ignores the
+ tag check fault.
+
+- *Synchronous* - The kernel raises a ``SIGSEGV`` synchronously, with
+ ``.si_code = SEGV_MTESERR`` and ``.si_addr = <fault-address>``. The
+ memory access is not performed. If ``SIGSEGV`` is ignored or blocked
+ by the offending thread, the containing process is terminated with a
+ ``coredump``.
+
+- *Asynchronous* - The kernel raises a ``SIGSEGV``, in the offending
+ thread, asynchronously following one or multiple tag check faults,
+ with ``.si_code = SEGV_MTEAERR`` and ``.si_addr = 0`` (the faulting
+ address is unknown).
+
+The user can select the above modes, per thread, using the
+``prctl(PR_SET_TAGGED_ADDR_CTRL, flags, 0, 0, 0)`` system call where
+``flags`` contain one of the following values in the ``PR_MTE_TCF_MASK``
+bit-field:
+
+- ``PR_MTE_TCF_NONE`` - *Ignore* tag check faults
+- ``PR_MTE_TCF_SYNC`` - *Synchronous* tag check fault mode
+- ``PR_MTE_TCF_ASYNC`` - *Asynchronous* tag check fault mode
+
+The current tag check fault mode can be read using the
+``prctl(PR_GET_TAGGED_ADDR_CTRL, 0, 0, 0, 0)`` system call.
+
+Tag checking can also be disabled for a user thread by setting the
+``PSTATE.TCO`` bit with ``MSR TCO, #1``.
+
+**Note**: Signal handlers are always invoked with ``PSTATE.TCO = 0``,
+irrespective of the interrupted context. ``PSTATE.TCO`` is restored on
+``sigreturn()``.
+
+**Note**: There are no *match-all* logical tags available for user
+applications.
+
+**Note**: Kernel accesses to the user address space (e.g. ``read()``
+system call) are not checked if the user thread tag checking mode is
+``PR_MTE_TCF_NONE`` or ``PR_MTE_TCF_ASYNC``. If the tag checking mode is
+``PR_MTE_TCF_SYNC``, the kernel makes a best effort to check its user
+address accesses, however it cannot always guarantee it.
+
+Excluding Tags in the ``IRG``, ``ADDG`` and ``SUBG`` instructions
+-----------------------------------------------------------------
+
+The architecture allows excluding certain tags to be randomly generated
+via the ``GCR_EL1.Exclude`` register bit-field. By default, Linux
+excludes all tags other than 0. A user thread can enable specific tags
+in the randomly generated set using the ``prctl(PR_SET_TAGGED_ADDR_CTRL,
+flags, 0, 0, 0)`` system call where ``flags`` contains the tags bitmap
+in the ``PR_MTE_TAG_MASK`` bit-field.
+
+**Note**: The hardware uses an exclude mask but the ``prctl()``
+interface provides an include mask. An include mask of ``0`` (exclusion
+mask ``0xffff``) results in the CPU always generating tag ``0``.
+
+Initial process state
+---------------------
+
+On ``execve()``, the new process has the following configuration:
+
+- ``PR_TAGGED_ADDR_ENABLE`` set to 0 (disabled)
+- Tag checking mode set to ``PR_MTE_TCF_NONE``
+- ``PR_MTE_TAG_MASK`` set to 0 (all tags excluded)
+- ``PSTATE.TCO`` set to 0
+- ``PROT_MTE`` not set on any of the initial memory maps
+
+On ``fork()``, the new process inherits the parent's configuration and
+memory map attributes with the exception of the ``madvise()`` ranges
+with ``MADV_WIPEONFORK`` which will have the data and tags cleared (set
+to 0).
+
+The ``ptrace()`` interface
+--------------------------
+
+``PTRACE_PEEKMTETAGS`` and ``PTRACE_POKEMTETAGS`` allow a tracer to read
+the tags from or set the tags to a tracee's address space. The
+``ptrace()`` system call is invoked as ``ptrace(request, pid, addr,
+data)`` where:
+
+- ``request`` - one of ``PTRACE_PEEKMTETAGS`` or ``PTRACE_POKEMTETAGS``.
+- ``pid`` - the tracee's PID.
+- ``addr`` - address in the tracee's address space.
+- ``data`` - pointer to a ``struct iovec`` where ``iov_base`` points to
+ a buffer of ``iov_len`` length in the tracer's address space.
+
+The tags in the tracer's ``iov_base`` buffer are represented as one
+4-bit tag per byte and correspond to a 16-byte MTE tag granule in the
+tracee's address space.
+
+**Note**: If ``addr`` is not aligned to a 16-byte granule, the kernel
+will use the corresponding aligned address.
+
+``ptrace()`` return value:
+
+- 0 - tags were copied, the tracer's ``iov_len`` was updated to the
+ number of tags transferred. This may be smaller than the requested
+ ``iov_len`` if the requested address range in the tracee's or the
+ tracer's space cannot be accessed or does not have valid tags.
+- ``-EPERM`` - the specified process cannot be traced.
+- ``-EIO`` - the tracee's address range cannot be accessed (e.g. invalid
+ address) and no tags copied. ``iov_len`` not updated.
+- ``-EFAULT`` - fault on accessing the tracer's memory (``struct iovec``
+ or ``iov_base`` buffer) and no tags copied. ``iov_len`` not updated.
+- ``-EOPNOTSUPP`` - the tracee's address does not have valid tags (never
+ mapped with the ``PROT_MTE`` flag). ``iov_len`` not updated.
+
+**Note**: There are no transient errors for the requests above, so user
+programs should not retry in case of a non-zero system call return.
+
+``PTRACE_GETREGSET`` and ``PTRACE_SETREGSET`` with ``addr ==
+``NT_ARM_TAGGED_ADDR_CTRL`` allow ``ptrace()`` access to the tagged
+address ABI control and MTE configuration of a process as per the
+``prctl()`` options described in
+Documentation/arm64/tagged-address-abi.rst and above. The corresponding
+``regset`` is 1 element of 8 bytes (``sizeof(long))``).

+=====================
+BPF sk_lookup program
+=====================
+
+BPF sk_lookup program type (``BPF_PROG_TYPE_SK_LOOKUP``) introduces programmability
+into the socket lookup performed by the transport layer when a packet is to be
+delivered locally.
+
+When invoked BPF sk_lookup program can select a socket that will receive the
+incoming packet by calling the ``bpf_sk_assign()`` BPF helper function.
+
+Hooks for a common attach point (``BPF_SK_LOOKUP``) exist for both TCP and UDP.
+
+Motivation
+==========
+
+BPF sk_lookup program type was introduced to address setup scenarios where
+binding sockets to an address with ``bind()`` socket call is impractical, such
+as:
+
+1. receiving connections on a range of IP addresses, e.g. 192.0.2.0/24, when
+ binding to a wildcard address ``INADRR_ANY`` is not possible due to a port
+ conflict,
+2. receiving connections on all or a wide range of ports, i.e. an L7 proxy use
+ case.
+
+Such setups would require creating and ``bind()``'ing one socket to each of the
+IP address/port in the range, leading to resource consumption and potential
+latency spikes during socket lookup.
+
+Attachment
+==========
+
+BPF sk_lookup program can be attached to a network namespace with
+``bpf(BPF_LINK_CREATE, ...)`` syscall using the ``BPF_SK_LOOKUP`` attach type and a
+netns FD as attachment ``target_fd``.
+
+Multiple programs can be attached to one network namespace. Programs will be
+invoked in the same order as they were attached.
+
+Hooks
+=====
+
+The attached BPF sk_lookup programs run whenever the transport layer needs to
+find a listening (TCP) or an unconnected (UDP) socket for an incoming packet.
+
+Incoming traffic to established (TCP) and connected (UDP) sockets is delivered
+as usual without triggering the BPF sk_lookup hook.
+
+The attached BPF programs must return with either ``SK_PASS`` or ``SK_DROP``
+verdict code. As for other BPF program types that are network filters,
+``SK_PASS`` signifies that the socket lookup should continue on to regular
+hashtable-based lookup, while ``SK_DROP`` causes the transport layer to drop the
+packet.
+
+A BPF sk_lookup program can also select a socket to receive the packet by
+calling ``bpf_sk_assign()`` BPF helper. Typically, the program looks up a socket
+in a map holding sockets, such as ``SOCKMAP`` or ``SOCKHASH``, and passes a
+``struct bpf_sock *`` to ``bpf_sk_assign()`` helper to record the
+selection. Selecting a socket only takes effect if the program has terminated
+with ``SK_PASS`` code.
+
+When multiple programs are attached, the end result is determined from return
+codes of all the programs according to the following rules:
+
+1. If any program returned ``SK_PASS`` and selected a valid socket, the socket
+ is used as the result of the socket lookup.
+2. If more than one program returned ``SK_PASS`` and selected a socket, the last
+ selection takes effect.
+3. If any program returned ``SK_DROP``, and no program returned ``SK_PASS`` and
+ selected a socket, socket lookup fails.
+4. If all programs returned ``SK_PASS`` and none of them selected a socket,
+ socket lookup continues on.
+
+API
+===
+
+In its context, an instance of ``struct bpf_sk_lookup``, BPF sk_lookup program
+receives information about the packet that triggered the socket lookup. Namely:
+
+* IP version (``AF_INET`` or ``AF_INET6``),
+* L4 protocol identifier (``IPPROTO_TCP`` or ``IPPROTO_UDP``),
+* source and destination IP address,
+* source and destination L4 port,
+* the socket that has been selected with ``bpf_sk_assign()``.
+
+Refer to ``struct bpf_sk_lookup`` declaration in ``linux/bpf.h`` user API
+header, and `bpf-helpers(7)
+<https://man7.org/linux/man-pages/man7/bpf-helpers.7.html>`_ man-page section
+for ``bpf_sk_assign()`` for details.
+
+Example
+=======
+
+See ``tools/testing/selftests/bpf/prog_tests/sk_lookup.c`` for the reference
+implementation.

+===========================
+Test Style and Nomenclature
+===========================
+
+To make finding, writing, and using KUnit tests as simple as possible, it's
+strongly encouraged that they are named and written according to the guidelines
+below. While it's possible to write KUnit tests which do not follow these rules,
+they may break some tooling, may conflict with other tests, and may not be run
+automatically by testing systems.
+
+It's recommended that you only deviate from these guidelines when:
+
+1. Porting tests to KUnit which are already known with an existing name, or
+2. Writing tests which would cause serious problems if automatically run (e.g.,
+ non-deterministically producing false positives or negatives, or taking an
+ extremely long time to run).
+
+Subsystems, Suites, and Tests
+=============================
+
+In order to make tests as easy to find as possible, they're grouped into suites
+and subsystems. A test suite is a group of tests which test a related area of
+the kernel, and a subsystem is a set of test suites which test different parts
+of the same kernel subsystem or driver.
+
+Subsystems
+----------
+
+Every test suite must belong to a subsystem. A subsystem is a collection of one
+or more KUnit test suites which test the same driver or part of the kernel. A
+rule of thumb is that a test subsystem should match a single kernel module. If
+the code being tested can't be compiled as a module, in many cases the subsystem
+should correspond to a directory in the source tree or an entry in the
+MAINTAINERS file. If unsure, follow the conventions set by tests in similar
+areas.
+
+Test subsystems should be named after the code being tested, either after the
+module (wherever possible), or after the directory or files being tested. Test
+subsystems should be named to avoid ambiguity where necessary.
+
+If a test subsystem name has multiple components, they should be separated by
+underscores. *Do not* include "test" or "kunit" directly in the subsystem name
+unless you are actually testing other tests or the kunit framework itself.
+
+Example subsystems could be:
+
+``ext4``
+ Matches the module and filesystem name.
+``apparmor``
+ Matches the module name and LSM name.
+``kasan``
+ Common name for the tool, prominent part of the path ``mm/kasan``
+``snd_hda_codec_hdmi``
+ Has several components (``snd``, ``hda``, ``codec``, ``hdmi``) separated by
+ underscores. Matches the module name.
+
+Avoid names like these:
+
+``linear-ranges``
+ Names should use underscores, not dashes, to separate words. Prefer
+ ``linear_ranges``.
+``qos-kunit-test``
+ As well as using underscores, this name should not have "kunit-test" as a
+ suffix, and ``qos`` is ambiguous as a subsystem name. ``power_qos`` would be a
+ better name.
+``pc_parallel_port``
+ The corresponding module name is ``parport_pc``, so this subsystem should also
+ be named ``parport_pc``.
+
+.. note::
+ The KUnit API and tools do not explicitly know about subsystems. They're
+ simply a way of categorising test suites and naming modules which
+ provides a simple, consistent way for humans to find and run tests. This
+ may change in the future, though.
+
+Suites
+------
+
+KUnit tests are grouped into test suites, which cover a specific area of
+functionality being tested. Test suites can have shared initialisation and
+shutdown code which is run for all tests in the suite.
+Not all subsystems will need to be split into multiple test suites (e.g. simple drivers).
+
+Test suites are named after the subsystem they are part of. If a subsystem
+contains several suites, the specific area under test should be appended to the
+subsystem name, separated by an underscore.
+
+In the event that there are multiple types of test using KUnit within a
+subsystem (e.g., both unit tests and integration tests), they should be put into
+separate suites, with the type of test as the last element in the suite name.
+Unless these tests are actually present, avoid using ``_test``, ``_unittest`` or
+similar in the suite name.
+
+The full test suite name (including the subsystem name) should be specified as
+the ``.name`` member of the ``kunit_suite`` struct, and forms the base for the
+module name (see below).
+
+Example test suites could include:
+
+``ext4_inode``
+ Part of the ``ext4`` subsystem, testing the ``inode`` area.
+``kunit_try_catch``
+ Part of the ``kunit`` implementation itself, testing the ``try_catch`` area.
+``apparmor_property_entry``
+ Part of the ``apparmor`` subsystem, testing the ``property_entry`` area.
+``kasan``
+ The ``kasan`` subsystem has only one suite, so the suite name is the same as
+ the subsystem name.
+
+Avoid names like:
+
+``ext4_ext4_inode``
+ There's no reason to state the subsystem twice.
+``property_entry``
+ The suite name is ambiguous without the subsystem name.
+``kasan_integration_test``
+ Because there is only one suite in the ``kasan`` subsystem, the suite should
+ just be called ``kasan``. There's no need to redundantly add
+ ``integration_test``. Should a separate test suite with, for example, unit
+ tests be added, then that suite could be named ``kasan_unittest`` or similar.
+
+Test Cases
+----------
+
+Individual tests consist of a single function which tests a constrained
+codepath, property, or function. In the test output, individual tests' results
+will show up as subtests of the suite's results.
+
+Tests should be named after what they're testing. This is often the name of the
+function being tested, with a description of the input or codepath being tested.
+As tests are C functions, they should be named and written in accordance with
+the kernel coding style.
+
+.. note::
+ As tests are themselves functions, their names cannot conflict with
+ other C identifiers in the kernel. This may require some creative
+ naming. It's a good idea to make your test functions `static` to avoid
+ polluting the global namespace.
+
+Example test names include:
+
+``unpack_u32_with_null_name``
+ Tests the ``unpack_u32`` function when a NULL name is passed in.
+``test_list_splice``
+ Tests the ``list_splice`` macro. It has the prefix ``test_`` to avoid a
+ name conflict with the macro itself.
+
+
+Should it be necessary to refer to a test outside the context of its test suite,
+the *fully-qualified* name of a test should be the suite name followed by the
+test name, separated by a colon (i.e. ``suite:test``).
+
+Test Kconfig Entries
+====================
+
+Every test suite should be tied to a Kconfig entry.
+
+This Kconfig entry must:
+
+* be named ``CONFIG_<name>_KUNIT_TEST``: where <name> is the name of the test
+ suite.
+* be listed either alongside the config entries for the driver/subsystem being
+ tested, or be under [Kernel Hacking]→[Kernel Testing and Coverage]
+* depend on ``CONFIG_KUNIT``
+* be visible only if ``CONFIG_KUNIT_ALL_TESTS`` is not enabled.
+* have a default value of ``CONFIG_KUNIT_ALL_TESTS``.
+* have a brief description of KUnit in the help text
+
+Unless there's a specific reason not to (e.g. the test is unable to be built as
+a module), Kconfig entries for tests should be tristate.
+
+An example Kconfig entry:
+
+.. code-block:: none
+
+ config FOO_KUNIT_TEST
+ tristate "KUnit test for foo" if !KUNIT_ALL_TESTS
+ depends on KUNIT
+ default KUNIT_ALL_TESTS
+ help
+ This builds unit tests for foo.
+
+ For more information on KUnit and unit tests in general, please refer
+ to the KUnit documentation in Documentation/dev-tools/kunit
+
+ If unsure, say N
+
+
+Test File and Module Names
+==========================
+
+KUnit tests can often be compiled as a module. These modules should be named
+after the test suite, followed by ``_test``. If this is likely to conflict with
+non-KUnit tests, the suffix ``_kunit`` can also be used.
+
+The easiest way of achieving this is to name the file containing the test suite
+``<suite>_test.c`` (or, as above, ``<suite>_kunit.c``). This file should be
+placed next to the code under test.
+
+If the suite name contains some or all of the name of the test's parent
+directory, it may make sense to modify the source filename to reduce redundancy.
+For example, a ``foo_firmware`` suite could be in the ``foo/firmware_test.c``
+file.

-Hisilicon Hip06 Low Pin Count device
- Hisilicon Hip06 SoCs implement a Low Pin Count (LPC) controller, which
- provides I/O access to some legacy ISA devices.
- Hip06 is based on arm64 architecture where there is no I/O space. So, the
- I/O ports here are not CPU addresses, and there is no 'ranges' property in
- LPC device node.
-
-Required properties:
-- compatible: value should be as follows:
- (a) "hisilicon,hip06-lpc"
- (b) "hisilicon,hip07-lpc"
-- #address-cells: must be 2 which stick to the ISA/EISA binding doc.
-- #size-cells: must be 1 which stick to the ISA/EISA binding doc.
-- reg: base memory range where the LPC register set is mapped.
-
-Note:
- The node name before '@' must be "isa" to represent the binding stick to the
- ISA/EISA binding specification.
-
-Example:
-
-isa@a01b0000 {
- compatible = "hisilicon,hip06-lpc";
- #address-cells = <2>;
- #size-cells = <1>;
- reg = <0x0 0xa01b0000 0x0 0x1000>;

-SiFive FU540 PRCI bindings
-
-On the FU540 family of SoCs, most system-wide clock and reset integration
-is via the PRCI IP block.
-
-Required properties:
-- compatible: Should be "sifive,<chip>-prci". Only one value is
- supported: "sifive,fu540-c000-prci"
-- reg: Should describe the PRCI's register target physical address region
-- clocks: Should point to the hfclk device tree node and the rtcclk
- device tree node. The RTC clock here is not a time-of-day clock,
- but is instead a high-stability clock source for system timers
- and cycle counters.
-- #clock-cells: Should be <1>
-
-The clock consumer should specify the desired clock via the clock ID
-macros defined in include/dt-bindings/clock/sifive-fu540-prci.h.
-These macros begin with PRCI_CLK_.
-
-The hfclk and rtcclk nodes are required, and represent physical
-crystals or resonators located on the PCB. These nodes should be present
-underneath /, rather than /soc.
-
-Examples:
-
-/* under /, in PCB-specific DT data */
-hfclk: hfclk {
- #clock-cells = <0>;
- compatible = "fixed-clock";
- clock-frequency = <33333333>;

-Samsung micro-USB 11-pin connector
-==================================
-
-Samsung micro-USB 11-pin connector is an extension of micro-USB connector.
-It is present in multiple Samsung mobile devices.
-It has additional pins to route MHL traffic simultanously with USB.
-
-The bindings are superset of usb-connector bindings for micro-USB connector[1].
-
-Required properties:
-- compatible: must be: "samsung,usb-connector-11pin", "usb-b-connector",
-- type: must be "micro".
-
-Required nodes:
-- any data bus to the connector should be modeled using the OF graph bindings
- specified in bindings/graph.txt, unless the bus is between parent node and
- the connector. Since single connector can have multpile data buses every bus
- has assigned OF graph port number as follows:
- 0: High Speed (HS),
- 3: Mobile High-Definition Link (MHL), specific to 11-pin Samsung micro-USB.
-
-[1]: bindings/connector/usb-connector.yaml
-
-Example

-
-Micro-USB connector with HS lines routed via controller (MUIC) and MHL lines
-connected to HDMI-MHL bridge (sii8620):

- "anvo,anv32e61w"
- "microchip,25lc040"
- "st,m95m02"
- "st,m95256"
-
-- reg : chip select number

-- pagesize : size of the eeprom page
-- size : total eeprom size in bytes
-- address-width : number of address bits (one of 8, 9, 16, or 24).
- For 9 bits, the MSB of the address is sent as bit 3 of the instruction
- byte, before the address byte.
-
-Optional properties:
-- spi-cpha : SPI shifted clock phase, as per spi-bus bindings.
-- spi-cpol : SPI inverse clock polarity, as per spi-bus bindings.
-- read-only : this parameter-less property disables writes to the eeprom
-- wp-gpios : GPIO to which the write-protect pin of the chip is connected
-
-Obsolete legacy properties can be used in place of "size", "pagesize",
-"address-width", and "read-only":
-- at25,byte-len : total eeprom size in bytes
-- at25,addr-mode : addr-mode flags, as defined in include/linux/spi/eeprom.h
-- at25,page-size : size of the eeprom page
-
-Additional compatible properties are also allowed.

-* Freescale VF610 PORT/GPIO module
-
-The Freescale PORT/GPIO modules are two adjacent modules providing GPIO
-functionality. Each pair serves 32 GPIOs. The VF610 has 5 instances of
-each, and each PORT module has its own interrupt.
-
-Required properties for GPIO node:
-- compatible : Should be "fsl,<soc>-gpio", below is supported list:
- "fsl,vf610-gpio"
- "fsl,imx7ulp-gpio"
-- reg : The first reg tuple represents the PORT module, the second tuple
- the GPIO module.
-- interrupts : Should be the port interrupt shared by all 32 pins.
-- gpio-controller : Marks the device node as a gpio controller.
-- #gpio-cells : Should be two. The first cell is the pin number and
- the second cell is used to specify the gpio polarity:
- 0 = active high
- 1 = active low
-- interrupt-controller: Marks the device node as an interrupt controller.
-- #interrupt-cells : Should be 2. The first cell is the GPIO number.
- The second cell bits[3:0] is used to specify 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.
-
-Optional properties:
--clocks: Must contain an entry for each entry in clock-names.
- See common clock-bindings.txt for details.
--clock-names: A list of clock names. For imx7ulp, it must contain
- "gpio", "port".
-
-Note: Each GPIO port should have an alias correctly numbered in "aliases"
-node.
-
-Examples:
-
-aliases {
- gpio0 = &gpio1;
- gpio1 = &gpio2;

-TI HwSpinlock for OMAP and K3 based SoCs
-=========================================
-
-Required properties:
-- compatible: Should be one of the following,
- "ti,omap4-hwspinlock" for
- OMAP44xx, OMAP54xx, AM33xx, AM43xx, DRA7xx SoCs
- "ti,am654-hwspinlock" for
- K3 AM65x and J721E SoCs
-- reg: Contains the hwspinlock module register address space
- (base address and length)
-- ti,hwmods: Name of the hwmod associated with the hwspinlock device
- (for OMAP architecture based SoCs only)
-- #hwlock-cells: Should be 1. The OMAP hwspinlock users will use a
- 0-indexed relative hwlock number as the argument
- specifier value for requesting a specific hwspinlock
- within a hwspinlock bank.
-
-Please look at the generic hwlock binding for usage information for consumers,
-"Documentation/devicetree/bindings/hwlock/hwlock.txt"

+description: |
+ The MAX20730 is a fully integrated, highly efficient switching regulator
+ with PMBus for applications operating from 4.5V to 16V and requiring
+ up to 25A (max) load. This single-chip regulator provides extremely
+ compact, high efficiency power-delivery solutions with high-precision
+ output voltages and excellent transient response.

+Required Properties:
+
+- compatible : should be "mellanox,i2c-mlxbf1" or "mellanox,i2c-mlxbf2".
+
+- reg : address offset and length of the device registers. The
+ registers consist of the following set of resources:
+ 1) Smbus block registers.
+ 2) Cause master registers.
+ 3) Cause slave registers.
+ 4) Cause coalesce registers (if compatible isn't set

+
+- interrupts : interrupt number.
+
+Optional Properties:
+
+- clock-frequency : bus frequency used to configure timing registers;
+ allowed values are 100000, 400000 and 1000000;
+ those are expressed in Hz. Default is 100000.

-Required properties for the AD7768-1:
-
-- compatible: Must be "adi,ad7768-1"
-- reg: SPI chip select number for the device
-- spi-max-frequency: Max SPI frequency to use
- see: Documentation/devicetree/bindings/spi/spi-bus.txt
-- clocks: phandle to the master clock (mclk)
- see: Documentation/devicetree/bindings/clock/clock-bindings.txt
-- clock-names: Must be "mclk".
-- interrupts: IRQ line for the ADC
- see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-- vref-supply: vref supply can be used as reference for conversion
-- adi,sync-in-gpios: must be the device tree identifier of the SYNC-IN pin. Enables
- synchronization of multiple devices that require simultaneous sampling.
- A pulse is always required if the configuration is changed in any way, for example
- if the filter decimation rate changes. As the line is active low, it should
- be marked GPIO_ACTIVE_LOW.
-
-Optional properties:
-
- - reset-gpios : GPIO spec for the RESET pin. If specified, it will be asserted during
- driver probe. As the line is active low, it should be marked GPIO_ACTIVE_LOW.
-
-Example:
-
- adc@0 {
- compatible = "adi,ad7768-1";
- reg = <0>;

-Nuvoton NPCM Analog to Digital Converter (ADC)
-
-The NPCM ADC is a 10-bit converter for eight channel inputs.
-
-Required properties:
-- compatible: "nuvoton,npcm750-adc" for the NPCM7XX BMC.
-- reg: specifies physical base address and size of the registers.
-- interrupts: Contain the ADC interrupt with flags for falling edge.
-- resets : phandle to the reset control for this device.
-
-Optional properties:
-- clocks: phandle of ADC reference clock, in case the clock is not
- added the ADC will use the default ADC sample rate.
-- vref-supply: The regulator supply ADC reference voltage, in case the
- vref-supply is not added the ADC will use internal voltage
- reference.
-
-Example:
-
-adc: adc@f000c000 {
- compatible = "nuvoton,npcm750-adc";
- reg = <0xf000c000 0x8>;
- interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;

-Freescale vf610 Analog to Digital Converter bindings
-
-The devicetree bindings are for the new ADC driver written for
-vf610/i.MX6slx and upward SoCs from Freescale.
-
-Required properties:
-- compatible: Should contain "fsl,vf610-adc"
-- reg: Offset and length of the register set for the device
-- interrupts: Should contain the interrupt for the device
-- clocks: The clock is needed by the ADC controller, ADC clock source is ipg clock.
-- clock-names: Must contain "adc", matching entry in the clocks property.
-- vref-supply: The regulator supply ADC reference voltage.
-
-Recommended properties:
-- fsl,adck-max-frequency: Maximum frequencies according to datasheets operating
- requirements. Three values are required, depending on conversion mode:
- - Frequency in normal mode (ADLPC=0, ADHSC=0)
- - Frequency in high-speed mode (ADLPC=0, ADHSC=1)
- - Frequency in low-power mode (ADLPC=1, ADHSC=0)
-- min-sample-time: Minimum sampling time in nanoseconds. This value has
- to be chosen according to the conversion mode and the connected analog
- source resistance (R_as) and capacitance (C_as). Refer the datasheet's
- operating requirements. A safe default across a wide range of R_as and
- C_as as well as conversion modes is 1000ns.
-
-Example:
-adc0: adc@4003b000 {
- compatible = "fsl,vf610-adc";
- reg = <0x4003b000 0x1000>;
- interrupts = <0 53 0x04>;

-* Meta External Trigger Controller Binding
-
-This binding specifies what properties must be available in the device tree
-representation of a Meta external trigger controller.
-
-Required properties:
-
- - compatible: Specifies the compatibility list for the interrupt controller.
- The type shall be <string> and the value shall include "img,meta-intc".
-
- - num-banks: Specifies the number of interrupt banks (each of which can
- handle 32 interrupt sources).
-
- - interrupt-controller: The presence of this property identifies the node
- as an interrupt controller. No property value shall be defined.
-
- - #interrupt-cells: Specifies the number of cells needed to encode an
- interrupt source. The type shall be a <u32> and the value shall be 2.
-
- - #address-cells: Specifies the number of cells needed to encode an
- address. The type shall be <u32> and the value shall be 0. As such,
- 'interrupt-map' nodes do not have to specify a parent unit address.
-
-Optional properties:
-
- - no-mask: The controller doesn't have any mask registers.
-
-* Interrupt Specifier Definition
-
- Interrupt specifiers consists of 2 cells encoded as follows:
-
- - <1st-cell>: The interrupt-number that identifies the interrupt source.
-
- - <2nd-cell>: The Linux interrupt flags containing level-sense information,
- encoded as follows:
- 1 = edge triggered
- 4 = level-sensitive
-
-* Examples
-
-Example 1:
-
- /*
- * Meta external trigger block
- */
- intc: intc {
- // This is an interrupt controller node.
- interrupt-controller;
-
- // No address cells so that 'interrupt-map' nodes which
- // reference this interrupt controller node do not need a parent
- // address specifier.
- #address-cells = <0>;
-
- // Two cells to encode interrupt sources.
- #interrupt-cells = <2>;
-
- // Number of interrupt banks
- num-banks = <2>;
-
- // No HWMASKEXT is available (specify on Chorus2 and Comet ES1)
- no-mask;
-
- // Compatible with Meta hardware trigger block.
- compatible = "img,meta-intc";
- };
-
-Example 2:
-
- /*
- * An interrupt generating device that is wired to a Meta external
- * trigger block.
- */
- uart1: uart@02004c00 {
- // Interrupt source '5' that is level-sensitive.
- // Note that there are only two cells as specified in the
- // interrupt parent's '#interrupt-cells' property.
- interrupts = <5 4 /* level */>;
-
- // The interrupt controller that this device is wired to.
- interrupt-parent = <&intc>;

-SiFive Platform-Level Interrupt Controller (PLIC)
--------------------------------------------------
-
-SiFive SOCs include an implementation of the Platform-Level Interrupt Controller
-(PLIC) high-level specification in the RISC-V Privileged Architecture
-specification. The PLIC connects all external interrupts in the system to all
-hart contexts in the system, via the external interrupt source in each hart.
-
-A hart context is a privilege mode in a hardware execution thread. For example,
-in an 4 core system with 2-way SMT, you have 8 harts and probably at least two
-privilege modes per hart; machine mode and supervisor mode.
-
-Each interrupt can be enabled on per-context basis. Any context can claim
-a pending enabled interrupt and then release it once it has been handled.
-
-Each interrupt has a configurable priority. Higher priority interrupts are
-serviced first. Each context can specify a priority threshold. Interrupts
-with priority below this threshold will not cause the PLIC to raise its
-interrupt line leading to the context.
-
-While the PLIC supports both edge-triggered and level-triggered interrupts,
-interrupt handlers are oblivious to this distinction and therefore it is not
-specified in the PLIC device-tree binding.
-
-While the RISC-V ISA doesn't specify a memory layout for the PLIC, the
-"sifive,plic-1.0.0" device is a concrete implementation of the PLIC that
-contains a specific memory layout, which is documented in chapter 8 of the
-SiFive U5 Coreplex Series Manual <https://static.dev.sifive.com/U54-MC-RVCoreIP.pdf>.
-
-Required properties:
-- compatible : "sifive,plic-1.0.0" and a string identifying the actual
- detailed implementation in case that specific bugs need to be worked around.
-- #address-cells : should be <0> or more.
-- #interrupt-cells : should be <1> or more.
-- interrupt-controller : Identifies the node as an interrupt controller.
-- reg : Should contain 1 register range (address and length).
-- interrupts-extended : Specifies which contexts are connected to the PLIC,
- with "-1" specifying that a context is not present. Each node pointed
- to should be a riscv,cpu-intc node, which has a riscv node as parent.
-- riscv,ndev: Specifies how many external interrupts are supported by
- this controller.
-
-Example:
-
- plic: interrupt-controller@c000000 {
- #address-cells = <0>;
- #interrupt-cells = <1>;
- compatible = "sifive,plic-1.0.0", "sifive,fu540-c000-plic";
- interrupt-controller;
- interrupts-extended = <

- reg = <0xc000000 0x4000000>;
- riscv,ndev = <10>;

+description: |
+ Each PRU-ICSS has a single interrupt controller instance that is common
+ to all the PRU cores. Most interrupt controllers can route 64 input events
+ which are then mapped to 10 possible output interrupts through two levels
+ of mapping. The input events can be triggered by either the PRUs and/or
+ various other PRUSS internal and external peripherals. The first 2 output
+ interrupts (0, 1) are fed exclusively to the internal PRU cores, with the
+ remaining 8 (2 through 9) connected to external interrupt controllers
+ including the MPU and/or other PRUSS instances, DSPs or devices.
+
+ The property "ti,irqs-reserved" is used for denoting the connection
+ differences on the output interrupts 2 through 9. If this property is not
+ defined, it implies that all the PRUSS INTC output interrupts 2 through 9
+ (host_intr0 through host_intr7) are connected exclusively to the Arm interrupt
+ controller.
+
+ The K3 family of SoCs can handle 160 input events that can be mapped to 20
+ different possible output interrupts. The additional output interrupts (10
+ through 19) are connected to new sub-modules within the ICSSG instances.
+
+ This interrupt-controller node should be defined as a child node of the

+description: |
+ The ARM's Message-Handling-Unit (MHU) is a mailbox controller that has 3
+ independent channels/links to communicate with remote processor(s). MHU links
+ are hardwired on a platform. A link raises interrupt for any received data.
+ However, there is no specified way of knowing if the sent data has been read
+ by the remote. This driver assumes the sender polls STAT register and the
+ remote clears it after having read the data. The last channel is specified to
+ be a 'Secure' resource, hence can't be used by Linux running NS.
+
+ The MHU hardware also allows operations in doorbell mode. The MHU drives the
+ interrupt signal using a 32-bit register, with all 32-bits logically ORed
+ together. It provides a set of registers to enable software to set, clear and
+ check the status of each of the bits of this register independently. The use
+ of 32 bits per interrupt line enables software to provide more information
+ about the source of the interrupt. For example, each bit of the register can
+ be associated with a type of event that can contribute to raising the
+ interrupt. Each of the 32-bits can be used as "doorbell" to alert the remote
+ processor.

-ARM MHU Mailbox Driver
-======================
-
-The ARM's Message-Handling-Unit (MHU) is a mailbox controller that has
-3 independent channels/links to communicate with remote processor(s).
- MHU links are hardwired on a platform. A link raises interrupt for any
-received data. However, there is no specified way of knowing if the sent
-data has been read by the remote. This driver assumes the sender polls
-STAT register and the remote clears it after having read the data.
-The last channel is specified to be a 'Secure' resource, hence can't be
-used by Linux running NS.
-
-Mailbox Device Node:
-====================
-
-Required properties:
---------------------
-- compatible: Shall be "arm,mhu" & "arm,primecell"
-- reg: Contains the mailbox register address range (base
- address and length)
-- #mbox-cells Shall be 1 - the index of the channel needed.
-- interrupts: Contains the interrupt information corresponding to
- each of the 3 links of MHU.
-
-Example:
---------
-

-Required Properties:
- - compatible: should be one of:
- "ti,am654-sdhci-5.1": SDHCI on AM654 device.
- "ti,j721e-sdhci-8bit": 8 bit SDHCI on J721E device.
- "ti,j721e-sdhci-4bit": 4 bit SDHCI on J721E device.
- - reg: Must be two entries.
- - The first should be the sdhci register space
- - The second should the subsystem/phy register space
- - clocks: Handles to the clock inputs.
- - clock-names: Tuple including "clk_xin" and "clk_ahb"
- - interrupts: Interrupt specifiers
- Output tap delay for each speed mode:
- - ti,otap-del-sel-legacy
- - ti,otap-del-sel-mmc-hs
- - ti,otap-del-sel-sd-hs
- - ti,otap-del-sel-sdr12

- - ti,otap-del-sel-ddr52
- - ti,otap-del-sel-hs200
- - ti,otap-del-sel-hs400
- These bindings must be provided otherwise the driver will disable the
- corresponding speed mode (i.e. all nodes must provide at least -legacy)
-
-Optional Properties (Required for ti,am654-sdhci-5.1 and ti,j721e-sdhci-8bit):
- - ti,trm-icp: DLL trim select
- - ti,driver-strength-ohm: driver strength in ohms.

+Marvell Prestera SwitchDev bindings
+-----------------------------------
+Optional properties:
+- compatible: must be "marvell,prestera"
+- base-mac-provider: describes handle to node which provides base mac address,
+ might be a static base mac address or nvme cell provider.
+
+Example:
+
+eeprom_mac_addr: eeprom-mac-addr {
+ compatible = "eeprom,mac-addr-cell";
+ status = "okay";
+

+ status = "okay";
+
+ base-mac-provider = <&eeprom_mac_addr>;

-
-Optional properties:
-- interrupt-names: A list of interrupt names.
- For the R-Car Gen 3 SoCs this property is mandatory;
- it should include one entry per channel, named "ch%u",
- where %u is the channel number ranging from 0 to 24.
- For other SoCs this property is optional; if present
- it should contain "mux" for a single muxed interrupt.
-- pinctrl-names: pin configuration state name ("default").

+description: |
+ The DP83822 is a low-power, single-port, 10/100 Mbps Ethernet PHY. It
+ provides all of the physical layer functions needed to transmit and receive
+ data over standard, twisted-pair cables or to connect to an external,
+ fiber-optic transceiver. Additionally, the DP83822 provides flexibility to
+ connect to a MAC through a standard MII, RMII, or RGMII interface

- opp-suspend: Marks the OPP to be used during device suspend. If multiple OPPs
in the table have this, the OPP with highest opp-hz will be used.
-- opp-supported-hw: This enables us to select only a subset of OPPs from the
- larger OPP table, based on what version of the hardware we are running on. We
- still can't have multiple nodes with the same opp-hz value in OPP table.
-
- It's a user defined array containing a hierarchy of hardware version numbers,
- supported by the OPP. For example: a platform with hierarchy of three levels
- of versions (A, B and C), this field should be like <X Y Z>, where X
- corresponds to Version hierarchy A, Y corresponds to version hierarchy B and Z
- corresponds to version hierarchy C.
-
- Each level of hierarchy is represented by a 32 bit value, and so there can be
- only 32 different supported version per hierarchy. i.e. 1 bit per version. A
- value of 0xFFFFFFFF will enable the OPP for all versions for that hierarchy
- level. And a value of 0x00000000 will disable the OPP completely, and so we
- never want that to happen.
-
- If 32 values aren't sufficient for a version hierarchy, than that version
- hierarchy can be contained in multiple 32 bit values. i.e. <X Y Z1 Z2> in the
- above example, Z1 & Z2 refer to the version hierarchy Z.
+- opp-supported-hw: This property allows a platform to enable only a subset of
+ the OPPs from the larger set present in the OPP table, based on the current
+ version of the hardware (already known to the operating system).
+
+ Each block present in the array of blocks in this property, represents a
+ sub-group of hardware versions supported by the OPP. i.e. <sub-group A>,
+ <sub-group B>, etc. The OPP will be enabled if _any_ of these sub-groups match
+ the hardware's version.
+
+ Each sub-group is a platform defined array representing the hierarchy of
+ hardware versions supported by the platform. For a platform with three
+ hierarchical levels of version (X.Y.Z), this field shall look like
+
+ opp-supported-hw = <X1 Y1 Z1>, <X2 Y2 Z2>, <X3 Y3 Z3>.
+
+ Each level (eg. X1) in version hierarchy is represented by a 32 bit value, one
+ bit per version and so there can be maximum 32 versions per level. Logical AND
+ (&) operation is performed for each level with the hardware's level version
+ and a non-zero output for _all_ the levels in a sub-group means the OPP is
+ supported by hardware. A value of 0xFFFFFFFF for each level in the sub-group
+ will enable the OPP for all versions for the hardware.

- - reg: Base address and length of each memory resource used by the pin

-
-Optional properties:
-
- - #gpio-range-cells: Mandatory when the PFC doesn't handle GPIO, forbidden
- otherwise. Should be 3.
-
- - interrupts-extended: Specify the interrupts associated with external
- IRQ pins. This property is mandatory when the PFC handles GPIOs and
- forbidden otherwise. When specified, it must contain one interrupt per
- external IRQ, sorted by external IRQ number.
-
-The PFC node also acts as a container for pin configuration nodes. Please refer
-to pinctrl-bindings.txt in this directory for the definition of the term "pin
-configuration node" and for the common pinctrl bindings used by client devices.
-
-Each pin configuration node represents a desired configuration for a pin, a
-pin group, or a list of pins or pin groups. The configuration can include the
-function to select on those pin(s) and pin configuration parameters (such as
-pull-up and pull-down).
-
-Pin configuration nodes contain pin configuration properties, either directly
-or grouped in child subnodes. Both pin muxing and configuration parameters can
-be grouped in that way and referenced as a single pin configuration node by
-client devices.
-
-A configuration node or subnode must reference at least one pin (through the
-pins or pin groups properties) and contain at least a function or one
-configuration parameter. When the function is present only pin groups can be
-used to reference pins.
-
-All pin configuration nodes and subnodes names are ignored. All of those nodes
-are parsed through phandles and processed purely based on their content.
-
-Pin Configuration Node Properties:
-
-- pins : An array of strings, each string containing the name of a pin.
-- groups : An array of strings, each string containing the name of a pin
- group.
-
-- function: A string containing the name of the function to mux to the pin
- group(s) specified by the groups property.
-
- Valid values for pin, group and function names can be found in the group and
- function arrays of the PFC data file corresponding to the SoC
- (drivers/pinctrl/sh-pfc/pfc-*.c)
-
-The pin configuration parameters use the generic pinconf bindings defined in
-pinctrl-bindings.txt in this directory. The supported parameters are
-bias-disable, bias-pull-up, bias-pull-down, drive-strength and power-source. For
-pins that have a configurable I/O voltage, the power-source value should be the
-nominal I/O voltage in millivolts.

- - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
- cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
- GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
-
-The syntax of the gpio specifier used by client nodes should be the following
-with values derived from the SoC user manual.
-
- <[phandle of the gpio controller node]
- [pin number within the gpio controller]
- [flags]>
-
-On other mach-shmobile platforms GPIO is handled by the gpio-rcar driver.
-Please refer to Documentation/devicetree/bindings/gpio/renesas,rcar-gpio.yaml
-for documentation of the GPIO device tree bindings on those platforms.

-Renesas RZ/A1 combined Pin and GPIO controller
-
-The Renesas SoCs of the RZ/A1 family feature a combined Pin and GPIO controller,
-named "Ports" in the hardware reference manual.
-Pin multiplexing and GPIO configuration is performed on a per-pin basis
-writing configuration values to per-port register sets.
-Each "port" features up to 16 pins, each of them configurable for GPIO
-function (port mode) or in alternate function mode.
-Up to 8 different alternate function modes exist for each single pin.
-
-Pin controller node
--------------------
-
-Required properties:
- - compatible: should be:
- - "renesas,r7s72100-ports": for RZ/A1H
- - "renesas,r7s72101-ports", "renesas,r7s72100-ports": for RZ/A1M
- - "renesas,r7s72102-ports": for RZ/A1L
-
- - reg
- address base and length of the memory area where the pin controller
- hardware is mapped to.
-
-Example:
-Pin controller node for RZ/A1H SoC (r7s72100)
-
-pinctrl: pin-controller@fcfe3000 {
- compatible = "renesas,r7s72100-ports";
-
- reg = <0xfcfe3000 0x4230>;
-};
-
-Sub-nodes
----------
-
-The child nodes of the pin controller node describe a pin multiplexing
-function or a GPIO controller alternatively.
-
-- Pin multiplexing sub-nodes:
- A pin multiplexing sub-node describes how to configure a set of
- (or a single) pin in some desired alternate function mode.
- A single sub-node may define several pin configurations.
- A few alternate function require special pin configuration flags to be
- supplied along with the alternate function configuration number.
- The hardware reference manual specifies when a pin function requires
- "software IO driven" mode to be specified. To do so use the generic
- properties from the <include/linux/pinctrl/pinconf_generic.h> header file
- to instruct the pin controller to perform the desired pin configuration
- operation.
- Please refer to pinctrl-bindings.txt to get to know more on generic
- pin properties usage.
-
- The allowed generic formats for a pin multiplexing sub-node are the
- following ones:
-
- node-1 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- node-2 {
- sub-node-1 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- sub-node-2 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- ...
-
- sub-node-n {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
- };
-
- Use the second format when pins part of the same logical group need to have
- different generic pin configuration flags applied.
-
- Client sub-nodes shall refer to pin multiplexing sub-nodes using the phandle
- of the most external one.
-
- Eg.
-
- client-1 {
- ...
- pinctrl-0 = <&node-1>;
- ...
- };
-
- client-2 {
- ...
- pinctrl-0 = <&node-2>;
- ...
- };
-
- Required properties:
- - pinmux:
- integer array representing pin number and pin multiplexing configuration.
- When a pin has to be configured in alternate function mode, use this
- property to identify the pin by its global index, and provide its
- alternate function configuration number along with it.
- When multiple pins are required to be configured as part of the same
- alternate function they shall be specified as members of the same
- argument list of a single "pinmux" property.
- Helper macros to ease assembling the pin index from its position
- (port where it sits on and pin number) and alternate function identifier
- are provided by the pin controller header file at:
- <include/dt-bindings/pinctrl/r7s72100-pinctrl.h>
- Integers values in "pinmux" argument list are assembled as:
- ((PORT * 16 + PIN) | MUX_FUNC << 16)
-
- Optional generic properties:
- - input-enable:
- enable input bufer for pins requiring software driven IO input
- operations.
- - output-high:
- enable output buffer for pins requiring software driven IO output
- operations. output-low can be used alternatively, as line value is
- ignored by the driver.
-
- The hardware reference manual specifies when a pin has to be configured to
- work in bi-directional mode and when the IO direction has to be specified
- by software. Bi-directional pins are managed by the pin controller driver
- internally, while software driven IO direction has to be explicitly
- selected when multiple options are available.
-
- Example:
- A serial communication interface with a TX output pin and an RX input pin.
-
- &pinctrl {
- scif2_pins: serial2 {
- pinmux = <RZA1_PINMUX(3, 0, 6)>, <RZA1_PINMUX(3, 2, 4)>;
- };
- };
-
- Pin #0 on port #3 is configured as alternate function #6.
- Pin #2 on port #3 is configured as alternate function #4.
-
- Example 2:
- I2c master: both SDA and SCL pins need bi-directional operations
-
- &pinctrl {
- i2c2_pins: i2c2 {
- pinmux = <RZA1_PINMUX(1, 4, 1)>, <RZA1_PINMUX(1, 5, 1)>;
- };
- };
-
- Pin #4 on port #1 is configured as alternate function #1.
- Pin #5 on port #1 is configured as alternate function #1.
- Both need to work in bi-directional mode, the driver manages this internally.
-
- Example 3:
- Multi-function timer input and output compare pins.
- Configure TIOC0A as software driven input and TIOC0B as software driven
- output.
-
- &pinctrl {
- tioc0_pins: tioc0 {
- tioc0_input_pins {
- pinumx = <RZA1_PINMUX(4, 0, 2)>;
- input-enable;
- };
-
- tioc0_output_pins {
- pinmux = <RZA1_PINMUX(4, 1, 1)>;
- output-enable;
- };
- };
- };
-
- &tioc0 {
- ...
- pinctrl-0 = <&tioc0_pins>;
- ...
- };
-
- Pin #0 on port #4 is configured as alternate function #2 with IO direction
- specified by software as input.
- Pin #1 on port #4 is configured as alternate function #1 with IO direction
- specified by software as output.
-
-- GPIO controller sub-nodes:
- Each port of the r7s72100 pin controller hardware is itself a GPIO controller.
- Different SoCs have different numbers of available pins per port, but
- generally speaking, each of them can be configured in GPIO ("port") mode
- on this hardware.
- Describe GPIO controllers using sub-nodes with the following properties.
-
- Required properties:
- - gpio-controller
- empty property as defined by the GPIO bindings documentation.
- - #gpio-cells
- number of cells required to identify and configure a GPIO.
- Shall be 2.
- - gpio-ranges
- Describes a GPIO controller specifying its specific pin base, the pin
- base in the global pin numbering space, and the number of controlled
- pins, as defined by the GPIO bindings documentation. Refer to
- Documentation/devicetree/bindings/gpio/gpio.txt file for a more detailed
- description.
-
- Example:
- A GPIO controller node, controlling 16 pins indexed from 0.
- The GPIO controller base in the global pin indexing space is pin 48, thus
- pins [0 - 15] on this controller map to pins [48 - 63] in the global pin
- indexing space.
-
- port3: gpio-3 {
- gpio-controller;
- #gpio-cells = <2>;
- gpio-ranges = <&pinctrl 0 48 16>;
- };
-
- A device node willing to use pins controlled by this GPIO controller, shall
- refer to it as follows:
-
- led1 {
- gpios = <&port3 10 GPIO_ACTIVE_LOW>;
- };

-Renesas RZ/N1 SoC Pinctrl node description.
-
-Pin controller node
--------------------
-Required properties:
-- compatible: SoC-specific compatible string "renesas,<soc-specific>-pinctrl"
- followed by "renesas,rzn1-pinctrl" as fallback. The SoC-specific compatible
- strings must be one of:
- "renesas,r9a06g032-pinctrl" for RZ/N1D
- "renesas,r9a06g033-pinctrl" for RZ/N1S
-- reg: Address base and length of the memory area where the pin controller
- hardware is mapped to.
-- clocks: phandle for the clock, see the description of clock-names below.
-- clock-names: Contains the name of the clock:
- "bus", the bus clock, sometimes described as pclk, for register accesses.
-
-Example:
- pinctrl: pin-controller@40067000 {
- compatible = "renesas,r9a06g032-pinctrl", "renesas,rzn1-pinctrl";
- reg = <0x40067000 0x1000>, <0x51000000 0x480>;
- clocks = <&sysctrl R9A06G032_HCLK_PINCONFIG>;
- clock-names = "bus";
- };
-
-Sub-nodes
----------
-
-The child nodes of the pin controller node describe a pin multiplexing
-function.
-
-- Pin multiplexing sub-nodes:
- A pin multiplexing sub-node describes how to configure a set of
- (or a single) pin in some desired alternate function mode.
- A single sub-node may define several pin configurations.
- Please refer to pinctrl-bindings.txt to get to know more on generic
- pin properties usage.
-
- The allowed generic formats for a pin multiplexing sub-node are the
- following ones:
-
- node-1 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- node-2 {
- sub-node-1 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- sub-node-2 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- ...
-
- sub-node-n {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
- };
-
- node-3 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
-
- sub-node-1 {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
-
- ...
-
- sub-node-n {
- pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
- GENERIC_PINCONFIG;
- };
- };
-
- Use the latter two formats when pins part of the same logical group need to
- have different generic pin configuration flags applied. Note that the generic
- pinconfig in node-3 does not apply to the sub-nodes.
-
- Client sub-nodes shall refer to pin multiplexing sub-nodes using the phandle
- of the most external one.
-
- Eg.
-
- client-1 {
- ...
- pinctrl-0 = <&node-1>;
- ...
- };
-
- client-2 {
- ...
- pinctrl-0 = <&node-2>;
- ...
- };
-
- Required properties:
- - pinmux:
- integer array representing pin number and pin multiplexing configuration.
- When a pin has to be configured in alternate function mode, use this
- property to identify the pin by its global index, and provide its
- alternate function configuration number along with it.
- When multiple pins are required to be configured as part of the same
- alternate function they shall be specified as members of the same
- argument list of a single "pinmux" property.
- Integers values in the "pinmux" argument list are assembled as:
- (PIN | MUX_FUNC << 8)
- where PIN directly corresponds to the pl_gpio pin number and MUX_FUNC is
- one of the alternate function identifiers defined in:
- <include/dt-bindings/pinctrl/rzn1-pinctrl.h>
- These identifiers collapse the IO Multiplex Configuration Level 1 and
- Level 2 numbers that are detailed in the hardware reference manual into a
- single number. The identifiers for Level 2 are simply offset by 10.
- Additional identifiers are provided to specify the MDIO source peripheral.
-
- Optional generic pinconf properties:
- - bias-disable - disable any pin bias
- - bias-pull-up - pull up the pin with 50 KOhm
- - bias-pull-down - pull down the pin with 50 KOhm
- - bias-high-impedance - high impedance mode
- - drive-strength - sink or source at most 4, 6, 8 or 12 mA
-
- Example:
- A serial communication interface with a TX output pin and an RX input pin.
-
- &pinctrl {
- pins_uart0: pins_uart0 {
- pinmux = <
- RZN1_PINMUX(103, RZN1_FUNC_UART0_I) /* UART0_TXD */
- RZN1_PINMUX(104, RZN1_FUNC_UART0_I) /* UART0_RXD */
- >;
- };
- };
-
- Example 2:
- Here we set the pull up on the RXD pin of the UART.
-
- &pinctrl {
- pins_uart0: pins_uart0 {
- pinmux = <RZN1_PINMUX(103, RZN1_FUNC_UART0_I)>; /* TXD */
-
- pins_uart6_rx {
- pinmux = <RZN1_PINMUX(104, RZN1_FUNC_UART0_I)>; /* RXD */
- bias-pull-up;
- };
- };
- };

+description: |
+ Devices on SOCs often have mechanisms for placing devices into low-power
+ states that are decoupled from the devices' own register blocks. Sometimes,
+ this information is more complicated than a cell-index property can
+ reasonably describe. Thus, each device controlled in such a manner
+ may contain a "sleep" property which describes these connections.
+
+ The sleep property consists of one or more sleep resources, each of
+ which consists of a phandle to a sleep controller, followed by a
+ controller-specific sleep specifier of zero or more cells.
+
+ The semantics of what type of low power modes are possible are defined
+ by the sleep controller. Some examples of the types of low power modes
+ that may be supported are:
+
+ - Dynamic: The device may be disabled or enabled at any time.
+ - System Suspend: The device may request to be disabled or remain
+ awake during system suspend, but will not be disabled until then.
+ - Permanent: The device is disabled permanently (until the next hard
+ reset).
+
+ Some devices may share a clock domain with each other, such that they should
+ only be suspended when none of the devices are in use. Where reasonable,
+ such nodes should be placed on a virtual bus, where the bus has the sleep
+ property. If the clock domain is shared among devices that cannot be
+ reasonably grouped in this manner, then create a virtual sleep controller
+ (similar to an interrupt nexus, except that defining a standardized
+ sleep-map should wait until its necessity is demonstrated).

-Unlike most other PWM controllers, the SiFive PWM controller currently only
-supports one period for all channels in the PWM. All PWMs need to run at

-PWM RTL that corresponds to the IP block version numbers can be found
-here:
-
-https://github.com/sifive/sifive-blocks/tree/master/src/main/scala/devices/pwm
-
-Required properties:
-- compatible: Should be "sifive,<chip>-pwm" and "sifive,pwm<version>".
- Supported compatible strings are: "sifive,fu540-c000-pwm" for the SiFive
- PWM v0 as integrated onto the SiFive FU540 chip, and "sifive,pwm0" for the
- SiFive PWM v0 IP block with no chip integration tweaks.
- Please refer to sifive-blocks-ip-versioning.txt for details.
-- reg: physical base address and length of the controller's registers
-- clocks: Should contain a clock identifier for the PWM's parent clock.
-- #pwm-cells: Should be 3. See pwm.yaml in this directory
- for a description of the cell format.
-- interrupts: one interrupt per PWM channel

-PFUZE100 family of regulators
-
-Required properties:
-- compatible: "fsl,pfuze100", "fsl,pfuze200", "fsl,pfuze3000", "fsl,pfuze3001"
-- reg: I2C slave address
-
-Optional properties:
-- fsl,pfuze-support-disable-sw: Boolean, if present disable all unused switch
- regulators to save power consumption. Attention, ensure that all important
- regulators (e.g. DDR ref, DDR supply) has set the "regulator-always-on"
- property. If not present, the switched regulators are always on and can't be
- disabled. This binding is a workaround to keep backward compatibility with
- old dtb's which rely on the fact that the switched regulators are always on
- and don't mark them explicit as "regulator-always-on".
-- fsl,pmic-stby-poweroff: if present, configure the PMIC to shutdown all
- power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
- Use this option if the SoC should be powered off by external power
- management IC (PMIC) on PMIC_STBY_REQ signal.
- As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.
-
-Required child node:
-- regulators: This is the list of child nodes that specify the regulator
- initialization data for defined regulators. Please refer to below doc
- Documentation/devicetree/bindings/regulator/regulator.txt.
-
- The valid names for regulators are:
- --PFUZE100
- sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
- --PFUZE200

+ Richtek RTMV20 is a load switch current regulator that can supply up to 6A.
+ It is used to drive laser diode. There're two signals for chip controls
+ (Enable/Fail), Enable pin to turn chip on, and Fail pin as fault indication.
+ There're still four pins for camera control, two inputs (strobe and vsync),
+ the others for outputs (fsin1 and fsin2). Strobe input to start the current
+ supply, vsync input from IR camera, and fsin1/fsin2 output for the optional.

+
+description: |
+ The TI K3 family of SoCs usually have one or more dual-core Arm Cortex R5F
+ processor subsystems/clusters (R5FSS). The dual core cluster can be used
+ either in a LockStep mode providing safety/fault tolerance features or in a
+ Split mode providing two individual compute cores for doubling the compute
+ capacity. These are used together with other processors present on the SoC
+ to achieve various system level goals.
+
+ Each Dual-Core R5F sub-system is represented as a single DTS node
+ representing the cluster, with a pair of child DT nodes representing
+ the individual R5F cores. Each node has a number of required or optional
+ properties that enable the OS running on the host processor to perform
+ the device management of the remote processor and to communicate with the
+ remote processor.

+ description: |
+ The R5F Sub-System device node should define two R5F child nodes, each
+ node representing a TI instantiation of the Arm Cortex R5F core. There
+ are some specific integration differences for the IP like the usage of
+ a Region Address Translator (RAT) for translating the larger SoC bus
+ addresses into a 32-bit address space for the processor.
+
+ Each R5F core has an associated 64 KB of Tightly-Coupled Memory (TCM)
+ internal memories split between two banks - TCMA and TCMB (further
+ interleaved into two banks TCMB0 and TCMB1). These memories (also called
+ ATCM and BTCM) provide read/write performance on par with the core's L1
+ caches. Each of the TCMs can be enabled or disabled independently and
+ either of them can be configured to appear at that R5F's address 0x0.
+
+ The cores do not use an MMU, but has a Region Address Translater
+ (RAT) module that is accessible only from the R5Fs for providing
+ translations between 32-bit CPU addresses into larger system bus
+ addresses. Cache and memory access settings are provided through a
+ Memory Protection Unit (MPU), programmable only from the R5Fs.

- "mod" - source for tick counter.
- "ahb" - ahb gate.
-
-Optional properties:
-- uart-has-rtscts : Indicate the UART has RTS and CTS lines
- for hardware flow control,
- it also means you enable the DMA support for this UART.
-- {rts,cts,dtr,dsr,rng,dcd}-gpios: specify a GPIO for RTS/CTS/DTR/DSR/RI/DCD
- line respectively. It will use specified PIO instead of the peripheral
- function pin for the USART feature.
- If unsure, don't specify this property.
-
-Example:
-auart0: serial@8006a000 {
- compatible = "fsl,imx28-auart", "fsl,imx23-auart";
- reg = <0x8006a000 0x2000>;
- interrupts = <112>;
- dmas = <&dma_apbx 8>, <&dma_apbx 9>;
- dma-names = "rx", "tx";
- cts-gpios = <&gpio1 15 GPIO_ACTIVE_LOW>;
- dsr-gpios = <&gpio1 16 GPIO_ACTIVE_LOW>;
- dcd-gpios = <&gpio1 17 GPIO_ACTIVE_LOW>;
-};
-
-Note: Each auart port should have an alias correctly numbered in "aliases"
-node.
-
-Example:
-
-aliases {
- serial0 = &auart0;
- serial1 = &auart1;
- serial2 = &auart2;
- serial3 = &auart3;
- serial4 = &auart4;

+
+description: |+
+
+ The Programmable Real-Time Unit and Industrial Communication Subsystem
+ (PRU-ICSS a.k.a. PRUSS) is present on various TI SoCs such as AM335x, AM437x,
+ Keystone 66AK2G, OMAP-L138/DA850 etc. A PRUSS consists of dual 32-bit RISC
+ cores (Programmable Real-Time Units, or PRUs), shared RAM, data and
+ instruction RAMs, some internal peripheral modules to facilitate industrial
+ communication, and an interrupt controller.
+
+ The programmable nature of the PRUs provide flexibility to implement custom
+ peripheral interfaces, fast real-time responses, or specialized data handling.
+ The common peripheral modules include the following,
+ - an Ethernet MII_RT module with two MII ports
+ - an MDIO port to control external Ethernet PHYs
+ - an Industrial Ethernet Peripheral (IEP) to manage/generate Industrial
+ Ethernet functions
+ - an Enhanced Capture Module (eCAP)
+ - an Industrial Ethernet Timer with 7/9 capture and 16 compare events
+ - a 16550-compatible UART to support PROFIBUS
+ - Enhanced GPIO with async capture and serial support
+
+ A PRU-ICSS subsystem can have up to three shared data memories. A PRU core
+ acts on a primary Data RAM (there are usually 2 Data RAMs) at its address
+ 0x0, but also has access to a secondary Data RAM (primary to the other PRU
+ core) at its address 0x2000. A shared Data RAM, if present, can be accessed
+ by both the PRU cores. The Interrupt Controller (INTC) and a CFG module are
+ common to both the PRU cores. Each PRU core also has a private instruction
+ RAM, and specific register spaces for Control and Debug functionalities.
+
+ Various sub-modules within a PRU-ICSS subsystem are represented as individual
+ nodes and are defined using a parent-child hierarchy depending on their
+ integration within the IP and the SoC. These nodes are described in the
+ following sections.
+
+
+ PRU-ICSS Node
+ ==============
+ Each PRU-ICSS instance is represented as its own node with the individual PRU
+ processor cores, the memories node, an INTC node and an MDIO node represented
+ as child nodes within this PRUSS node. This node shall be a child of the
+ corresponding interconnect bus nodes or target-module nodes.
+
+ See ../../mfd/syscon.yaml for generic SysCon binding details.

+description:
+ The CS4234 is a highly versatile CODEC that combines 4 channels of
+ high performance analog to digital conversion, 4 channels of high
+ performance digital to analog conversion for audio, and 1 channel of
+ digital to analog conversion to provide a nondelayed audio reference
+ signal to an external Class H tracking power supply. If not used to
+ drive a tracking power supply, the 5th DAC can instead be used as a
+ standard audio grade DAC, with performance specifications identical
+ to that of the 4 DACs in the audio path. Additionally, the CS4234
+ includes tunable group delay for each of the 4 audio DAC paths to
+ provide lead time for the external switch-mode power supply, and a
+ nondelayed path into the DAC outputs for input signals requiring a
+ low-latency path to the outputs.

-Freescale Sony/Philips Digital Interface Format (S/PDIF) Controller
-
-The Freescale S/PDIF audio block is a stereo transceiver that allows the
-processor to receive and transmit digital audio via an coaxial cable or
-a fibre cable.
-
-Required properties:
-
- - compatible : Compatible list, should contain one of the following
- compatibles:
- "fsl,imx35-spdif",
- "fsl,vf610-spdif",
- "fsl,imx6sx-spdif",
-
- - reg : Offset and length of the register set for the device.
-
- - interrupts : Contains the spdif interrupt.
-
- - dmas : Generic dma devicetree binding as described in
- Documentation/devicetree/bindings/dma/dma.txt.
-
- - dma-names : Two dmas have to be defined, "tx" and "rx".
-
- - clocks : Contains an entry for each entry in clock-names.
-
- - clock-names : Includes the following entries:
- "core" The core clock of spdif controller.
- "rxtx<0-7>" Clock source list for tx and rx clock.
- This clock list should be identical to the source
- list connecting to the spdif clock mux in "SPDIF
- Transceiver Clock Diagram" of SoC reference manual.
- It can also be referred to TxClk_Source bit of
- register SPDIF_STC.
- "spba" The spba clock is required when SPDIF is placed as a
- bus slave of the Shared Peripheral Bus and when two
- or more bus masters (CPU, DMA or DSP) try to access
- it. This property is optional depending on the SoC
- design.
-
-Optional properties:
-
- - big-endian : If this property is absent, the native endian mode
- will be in use as default, or the big endian mode
- will be in use for all the device registers.
-
-Example:
-
-spdif: spdif@2004000 {
- compatible = "fsl,imx35-spdif";
- reg = <0x02004000 0x4000>;

-
-
-
-Optional properties:
-
-- qcom,adsp : Phandle for the audio DSP node
-
-By default, the driver uses up to 4 MI2S SD lines, for a total of 8 channels.
-The SD lines to use can be configured by adding subnodes for each of the DAIs.
-
-Required properties for each DAI (represented by a subnode):
-- reg : Must be one of the DAI IDs
- (usually part of dt-bindings header)
-- qcom,playback-sd-lines: List of serial data lines to use for playback
- Each SD line should be represented by a number from 0-3.
-- qcom,capture-sd-lines : List of serial data lines to use for capture
- Each SD line should be represented by a number from 0-3.
-
-Note that adding a subnode changes the default to "no lines configured",
-so both playback and capture lines should be configured when a subnode is added.
-
-Example:
-

-
-Required properties:
- - #address-cells - Should be <1>.
- - #size-cells - Should be <0>.
- - compatible: - Should contain "ti,tas2562", "ti,tas2563".
- - reg: - The i2c address. Should be 0x4c, 0x4d, 0x4e or 0x4f.
- - ti,imon-slot-no:- TDM TX current sense time slot.
- - ti,vmon-slot-no:- TDM TX voltage sense time slot. This slot must always be
- greater then ti,imon-slot-no.

-There should be only one spi slave device following generic spi bindings.
-It's not recommended to use this controller for devices other than SPI NOR
-flash due to limited transfer capability of this controller.

- <&topckgen CLK_TOP_SPINFI_IFR_SEL>;
- clock-names = "spi", "sf";
- #address-cells = <1>;

-An SPMI controller node can contain zero or more child nodes representing slave

-These are the identifiers "statically assigned by the system integrator", as

-ARM AMBA Primecell SP805 Watchdog
-
-SP805 WDT is a ARM Primecell Peripheral and has a standard-id register that
-can be used to identify the peripheral type, vendor, and revision.
-This value can be used for driver matching.
-
-As SP805 WDT is a primecell IP, it follows the base bindings specified in
-'arm/primecell.txt'
-
-Required properties:
-- compatible: Should be "arm,sp805" & "arm,primecell"
-- reg: Should contain location and length for watchdog timer register
-- clocks: Clocks driving the watchdog timer hardware. This list should be
- 2 clocks. With 2 clocks, the order is wdog_clk, apb_pclk
- wdog_clk can be equal to or be a sub-multiple of the apb_pclk
- frequency
-- clock-names: Shall be "wdog_clk" for first clock and "apb_pclk" for the
- second one
-
-Optional properties:
-- interrupts: Should specify WDT interrupt number
-- timeout-sec: Should specify default WDT timeout in seconds. If unset, the
- default timeout is determined by the driver
-
-Example:
- watchdog@66090000 {
- compatible = "arm,sp805", "arm,primecell";
- reg = <0x66090000 0x1000>;
- interrupts = <GIC_SPI 406 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&wdt_clk>, <&apb_pclk>;

-Revision Information
-====================
-
- May 18, 2005: Rev 0.1
- - Initial draft, no chapter III yet.
-
- May 19, 2005: Rev 0.2
- - Add chapter III and bits & pieces here or
- clarifies the fact that a lot of things are
- optional, the kernel only requires a very
- small device tree, though it is encouraged
- to provide an as complete one as possible.
-
- May 24, 2005: Rev 0.3
- - Precise that DT block has to be in RAM
- - Misc fixes
- - Define version 3 and new format version 16
- for the DT block (version 16 needs kernel
- patches, will be fwd separately).
- String block now has a size, and full path
- is replaced by unit name for more
- compactness.
- linux,phandle is made optional, only nodes
- that are referenced by other nodes need it.
- "name" property is now automatically
- deduced from the unit name
-
- June 1, 2005: Rev 0.4
- - Correct confusion between OF_DT_END and
- OF_DT_END_NODE in structure definition.
- - Change version 16 format to always align
- property data to 4 bytes. Since tokens are
- already aligned, that means no specific
- required alignment between property size
- and property data. The old style variable
- alignment would make it impossible to do
- "simple" insertion of properties using
- memmove (thanks Milton for
- noticing). Updated kernel patch as well
- - Correct a few more alignment constraints
- - Add a chapter about the device-tree
- compiler and the textural representation of
- the tree that can be "compiled" by dtc.
-
- November 21, 2005: Rev 0.5
- - Additions/generalizations for 32-bit
- - Changed to reflect the new arch/powerpc
- structure
- - Added chapter VI
-
-
- ToDo:
- - Add some definitions of interrupt tree (simple/complex)
- - Add some definitions for PCI host bridges
- - Add some common address format examples
- - Add definitions for standard properties and "compatible"
- names for cells that are not already defined by the existing
- OF spec.
- - Compare FSL SOC use of PCI to standard and make sure no new
- node definition required.
- - Add more information about node definitions for SOC devices
- that currently have no standard, like the FSL CPM.

-I - Introduction
-================
-
-During the development of the Linux/ppc64 kernel, and more
-specifically, the addition of new platform types outside of the old
-IBM pSeries/iSeries pair, it was decided to enforce some strict rules
-regarding the kernel entry and bootloader <-> kernel interfaces, in
-order to avoid the degeneration that had become the ppc32 kernel entry
-point and the way a new platform should be added to the kernel. The
-legacy iSeries platform breaks those rules as it predates this scheme,
-but no new board support will be accepted in the main tree that
-doesn't follow them properly. In addition, since the advent of the
-arch/powerpc merged architecture for ppc32 and ppc64, new 32-bit
-platforms and 32-bit platforms which move into arch/powerpc will be
-required to use these rules as well.
-
-The main requirement that will be defined in more detail below is
-the presence of a device-tree whose format is defined after Open
-Firmware specification. However, in order to make life easier
-to embedded board vendors, the kernel doesn't require the device-tree
-to represent every device in the system and only requires some nodes
-and properties to be present. This will be described in detail in
-section III, but, for example, the kernel does not require you to
-create a node for every PCI device in the system. It is a requirement
-to have a node for PCI host bridges in order to provide interrupt
-routing information and memory/IO ranges, among others. It is also
-recommended to define nodes for on chip devices and other buses that
-don't specifically fit in an existing OF specification. This creates a
-great flexibility in the way the kernel can then probe those and match
-drivers to device, without having to hard code all sorts of tables. It
-also makes it more flexible for board vendors to do minor hardware
-upgrades without significantly impacting the kernel code or cluttering
-it with special cases.
-
-
-1) Entry point for arch/arm
----------------------------
-
- There is one single entry point to the kernel, at the start
- of the kernel image. That entry point supports two calling
- conventions. A summary of the interface is described here. A full
- description of the boot requirements is documented in
- Documentation/arm/booting.rst
-
- a) ATAGS interface. Minimal information is passed from firmware
- to the kernel with a tagged list of predefined parameters.
-
- r0 : 0
-
- r1 : Machine type number
-
- r2 : Physical address of tagged list in system RAM
-
- b) Entry with a flattened device-tree block. Firmware loads the
- physical address of the flattened device tree block (dtb) into r2,
- r1 is not used, but it is considered good practice to use a valid
- machine number as described in Documentation/arm/booting.rst.
-
- r0 : 0
-
- r1 : Valid machine type number. When using a device tree,
- a single machine type number will often be assigned to
- represent a class or family of SoCs.
-
- r2 : physical pointer to the device-tree block
- (defined in chapter II) in RAM. Device tree can be located
- anywhere in system RAM, but it should be aligned on a 64 bit
- boundary.
-
- The kernel will differentiate between ATAGS and device tree booting by
- reading the memory pointed to by r2 and looking for either the flattened
- device tree block magic value (0xd00dfeed) or the ATAG_CORE value at
- offset 0x4 from r2 (0x54410001).
-
-2) Entry point for arch/powerpc
--------------------------------
-
- There is one single entry point to the kernel, at the start
- of the kernel image. That entry point supports two calling
- conventions:
-
- a) Boot from Open Firmware. If your firmware is compatible
- with Open Firmware (IEEE 1275) or provides an OF compatible
- client interface API (support for "interpret" callback of
- forth words isn't required), you can enter the kernel with:
-
- r5 : OF callback pointer as defined by IEEE 1275
- bindings to powerpc. Only the 32-bit client interface
- is currently supported
-
- r3, r4 : address & length of an initrd if any or 0
-
- The MMU is either on or off; the kernel will run the
- trampoline located in arch/powerpc/kernel/prom_init.c to
- extract the device-tree and other information from open
- firmware and build a flattened device-tree as described
- in b). prom_init() will then re-enter the kernel using
- the second method. This trampoline code runs in the
- context of the firmware, which is supposed to handle all
- exceptions during that time.
-
- b) Direct entry with a flattened device-tree block. This entry
- point is called by a) after the OF trampoline and can also be
- called directly by a bootloader that does not support the Open
- Firmware client interface. It is also used by "kexec" to
- implement "hot" booting of a new kernel from a previous
- running one. This method is what I will describe in more
- details in this document, as method a) is simply standard Open
- Firmware, and thus should be implemented according to the
- various standard documents defining it and its binding to the
- PowerPC platform. The entry point definition then becomes:
-
- r3 : physical pointer to the device-tree block
- (defined in chapter II) in RAM
-
- r4 : physical pointer to the kernel itself. This is
- used by the assembly code to properly disable the MMU
- in case you are entering the kernel with MMU enabled
- and a non-1:1 mapping.
-
- r5 : NULL (as to differentiate with method a)
-
- Note about SMP entry: Either your firmware puts your other
- CPUs in some sleep loop or spin loop in ROM where you can get
- them out via a soft reset or some other means, in which case
- you don't need to care, or you'll have to enter the kernel
- with all CPUs. The way to do that with method b) will be
- described in a later revision of this document.
-
- Board supports (platforms) are not exclusive config options. An
- arbitrary set of board supports can be built in a single kernel
- image. The kernel will "know" what set of functions to use for a
- given platform based on the content of the device-tree. Thus, you
- should:
-
- a) add your platform support as a _boolean_ option in
- arch/powerpc/Kconfig, following the example of PPC_PSERIES,
- PPC_PMAC and PPC_MAPLE. The later is probably a good
- example of a board support to start from.
-
- b) create your main platform file as
- "arch/powerpc/platforms/myplatform/myboard_setup.c" and add it
- to the Makefile under the condition of your ``CONFIG_``
- option. This file will define a structure of type "ppc_md"
- containing the various callbacks that the generic code will
- use to get to your platform specific code
-
- A kernel image may support multiple platforms, but only if the
- platforms feature the same core architecture. A single kernel build
- cannot support both configurations with Book E and configurations
- with classic Powerpc architectures.
-
-3) Entry point for arch/x86
----------------------------
-
- There is one single 32bit entry point to the kernel at code32_start,
- the decompressor (the real mode entry point goes to the same 32bit
- entry point once it switched into protected mode). That entry point
- supports one calling convention which is documented in
- Documentation/x86/boot.rst
- The physical pointer to the device-tree block (defined in chapter II)
- is passed via setup_data which requires at least boot protocol 2.09.
- The type filed is defined as::
-
- #define SETUP_DTB 2
-
- This device-tree is used as an extension to the "boot page". As such it
- does not parse / consider data which is already covered by the boot
- page. This includes memory size, reserved ranges, command line arguments
- or initrd address. It simply holds information which can not be retrieved
- otherwise like interrupt routing or a list of devices behind an I2C bus.
-
-4) Entry point for arch/mips/bmips
-----------------------------------
-
- Some bootloaders only support a single entry point, at the start of the
- kernel image. Other bootloaders will jump to the ELF start address.
- Both schemes are supported; CONFIG_BOOT_RAW=y and CONFIG_NO_EXCEPT_FILL=y,
- so the first instruction immediately jumps to kernel_entry().
-
- Similar to the arch/arm case (b), a DT-aware bootloader is expected to
- set up the following registers:
-
- a0 : 0
-
- a1 : 0xffffffff
-
- a2 : Physical pointer to the device tree block (defined in chapter
- II) in RAM. The device tree can be located anywhere in the first
- 512MB of the physical address space (0x00000000 - 0x1fffffff),
- aligned on a 64 bit boundary.
-
- Legacy bootloaders do not use this convention, and they do not pass in a
- DT block. In this case, Linux will look for a builtin DTB, selected via
- CONFIG_DT_*.
-
- This convention is defined for 32-bit systems only, as there are not
- currently any 64-bit BMIPS implementations.
-
-5) Entry point for arch/sh
---------------------------
-
- Device-tree-compatible SH bootloaders are expected to provide the physical
- address of the device tree blob in r4. Since legacy bootloaders did not
- guarantee any particular initial register state, kernels built to
- inter-operate with old bootloaders must either use a builtin DTB or
- select a legacy board option (something other than CONFIG_SH_DEVICE_TREE)
- that does not use device tree. Support for the latter is being phased out
- in favor of device tree.
-
-
-II - The DT block format
-========================
-
-
-This chapter defines the actual format of the flattened device-tree
-passed to the kernel. The actual content of it and kernel requirements
-are described later. You can find example of code manipulating that
-format in various places, including arch/powerpc/kernel/prom_init.c
-which will generate a flattened device-tree from the Open Firmware
-representation, or the fs2dt utility which is part of the kexec tools
-which will generate one from a filesystem representation. It is
-expected that a bootloader like uboot provides a bit more support,
-that will be discussed later as well.
-
-Note: The block has to be in main memory. It has to be accessible in
-both real mode and virtual mode with no mapping other than main
-memory. If you are writing a simple flash bootloader, it should copy
-the block to RAM before passing it to the kernel.
-
-
-1) Header
----------
-
- The kernel is passed the physical address pointing to an area of memory
- that is roughly described in include/linux/of_fdt.h by the structure
- boot_param_header:::
-
- struct boot_param_header {
- u32 magic; /* magic word OF_DT_HEADER */
- u32 totalsize; /* total size of DT block */
- u32 off_dt_struct; /* offset to structure */
- u32 off_dt_strings; /* offset to strings */
- u32 off_mem_rsvmap; /* offset to memory reserve map
- */
- u32 version; /* format version */
- u32 last_comp_version; /* last compatible version */
-
- /* version 2 fields below */
- u32 boot_cpuid_phys; /* Which physical CPU id we're
- booting on */
- /* version 3 fields below */
- u32 size_dt_strings; /* size of the strings block */
-
- /* version 17 fields below */
- u32 size_dt_struct; /* size of the DT structure block */
- };
-
- Along with the constants::
-
- /* Definitions used by the flattened device tree */
- #define OF_DT_HEADER 0xd00dfeed /* 4: version,
- 4: total size */
- #define OF_DT_BEGIN_NODE 0x1 /* Start node: full name
- */
- #define OF_DT_END_NODE 0x2 /* End node */
- #define OF_DT_PROP 0x3 /* Property: name off,
- size, content */
- #define OF_DT_END 0x9
-
- All values in this header are in big endian format, the various
- fields in this header are defined more precisely below. All
- "offset" values are in bytes from the start of the header; that is
- from the physical base address of the device tree block.
-
- - magic
-
- This is a magic value that "marks" the beginning of the
- device-tree block header. It contains the value 0xd00dfeed and is
- defined by the constant OF_DT_HEADER
-
- - totalsize
-
- This is the total size of the DT block including the header. The
- "DT" block should enclose all data structures defined in this
- chapter (who are pointed to by offsets in this header). That is,
- the device-tree structure, strings, and the memory reserve map.
-
- - off_dt_struct
-
- This is an offset from the beginning of the header to the start
- of the "structure" part the device tree. (see 2) device tree)
-
- - off_dt_strings
-
- This is an offset from the beginning of the header to the start
- of the "strings" part of the device-tree
-
- - off_mem_rsvmap
-
- This is an offset from the beginning of the header to the start
- of the reserved memory map. This map is a list of pairs of 64-
- bit integers. Each pair is a physical address and a size. The
- list is terminated by an entry of size 0. This map provides the
- kernel with a list of physical memory areas that are "reserved"
- and thus not to be used for memory allocations, especially during
- early initialization. The kernel needs to allocate memory during
- boot for things like un-flattening the device-tree, allocating an
- MMU hash table, etc... Those allocations must be done in such a
- way to avoid overriding critical things like, on Open Firmware
- capable machines, the RTAS instance, or on some pSeries, the TCE
- tables used for the iommu. Typically, the reserve map should
- contain **at least** this DT block itself (header,total_size). If
- you are passing an initrd to the kernel, you should reserve it as
- well. You do not need to reserve the kernel image itself. The map
- should be 64-bit aligned.
-
- - version
-
- This is the version of this structure. Version 1 stops
- here. Version 2 adds an additional field boot_cpuid_phys.
- Version 3 adds the size of the strings block, allowing the kernel
- to reallocate it easily at boot and free up the unused flattened
- structure after expansion. Version 16 introduces a new more
- "compact" format for the tree itself that is however not backward
- compatible. Version 17 adds an additional field, size_dt_struct,
- allowing it to be reallocated or moved more easily (this is
- particularly useful for bootloaders which need to make
- adjustments to a device tree based on probed information). You
- should always generate a structure of the highest version defined
- at the time of your implementation. Currently that is version 17,
- unless you explicitly aim at being backward compatible.
-
- - last_comp_version
-
- Last compatible version. This indicates down to what version of
- the DT block you are backward compatible. For example, version 2
- is backward compatible with version 1 (that is, a kernel build
- for version 1 will be able to boot with a version 2 format). You
- should put a 1 in this field if you generate a device tree of
- version 1 to 3, or 16 if you generate a tree of version 16 or 17
- using the new unit name format.
-
- - boot_cpuid_phys
-
- This field only exist on version 2 headers. It indicate which
- physical CPU ID is calling the kernel entry point. This is used,
- among others, by kexec. If you are on an SMP system, this value
- should match the content of the "reg" property of the CPU node in
- the device-tree corresponding to the CPU calling the kernel entry
- point (see further chapters for more information on the required
- device-tree contents)
-
- - size_dt_strings
-
- This field only exists on version 3 and later headers. It
- gives the size of the "strings" section of the device tree (which
- starts at the offset given by off_dt_strings).
-
- - size_dt_struct
-
- This field only exists on version 17 and later headers. It gives
- the size of the "structure" section of the device tree (which
- starts at the offset given by off_dt_struct).
-
- So the typical layout of a DT block (though the various parts don't
- need to be in that order) looks like this (addresses go from top to
- bottom)::
-
-
- ------------------------------
- base -> | struct boot_param_header |

- --- (base + totalsize)
-
- (*) The alignment gaps are not necessarily present; their presence
- and size are dependent on the various alignment requirements of
- the individual data blocks.
-
-
-2) Device tree generalities
----------------------------
-
-This device-tree itself is separated in two different blocks, a
-structure block and a strings block. Both need to be aligned to a 4
-byte boundary.
-
-First, let's quickly describe the device-tree concept before detailing
-the storage format. This chapter does _not_ describe the detail of the
-required types of nodes & properties for the kernel, this is done
-later in chapter III.
-
-The device-tree layout is strongly inherited from the definition of
-the Open Firmware IEEE 1275 device-tree. It's basically a tree of
-nodes, each node having two or more named properties. A property can
-have a value or not.
-
-It is a tree, so each node has one and only one parent except for the
-root node who has no parent.
-
-A node has 2 names. The actual node name is generally contained in a
-property of type "name" in the node property list whose value is a
-zero terminated string and is mandatory for version 1 to 3 of the
-format definition (as it is in Open Firmware). Version 16 makes it
-optional as it can generate it from the unit name defined below.
-
-There is also a "unit name" that is used to differentiate nodes with
-the same name at the same level, it is usually made of the node
-names, the "@" sign, and a "unit address", which definition is
-specific to the bus type the node sits on.
-
-The unit name doesn't exist as a property per-se but is included in
-the device-tree structure. It is typically used to represent "path" in
-the device-tree. More details about the actual format of these will be
-below.
-
-The kernel generic code does not make any formal use of the
-unit address (though some board support code may do) so the only real
-requirement here for the unit address is to ensure uniqueness of
-the node unit name at a given level of the tree. Nodes with no notion
-of address and no possible sibling of the same name (like /memory or
-/cpus) may omit the unit address in the context of this specification,
-or use the "@0" default unit address. The unit name is used to define
-a node "full path", which is the concatenation of all parent node
-unit names separated with "/".
-
-The root node doesn't have a defined name, and isn't required to have
-a name property either if you are using version 3 or earlier of the
-format. It also has no unit address (no @ symbol followed by a unit
-address). The root node unit name is thus an empty string. The full
-path to the root node is "/".
-
-Every node which actually represents an actual device (that is, a node
-which isn't only a virtual "container" for more nodes, like "/cpus"
-is) is also required to have a "compatible" property indicating the
-specific hardware and an optional list of devices it is fully
-backwards compatible with.
-
-Finally, every node that can be referenced from a property in another
-node is required to have either a "phandle" or a "linux,phandle"
-property. Real Open Firmware implementations provide a unique
-"phandle" value for every node that the "prom_init()" trampoline code
-turns into "linux,phandle" properties. However, this is made optional
-if the flattened device tree is used directly. An example of a node
-referencing another node via "phandle" is when laying out the
-interrupt tree which will be described in a further version of this
-document.
-
-The "phandle" property is a 32-bit value that uniquely
-identifies a node. You are free to use whatever values or system of
-values, internal pointers, or whatever to generate these, the only
-requirement is that every node for which you provide that property has
-a unique value for it.
-
-Here is an example of a simple device-tree. In this example, an "o"
-designates a node followed by the node unit name. Properties are
-presented with their name followed by their content. "content"
-represents an ASCII string (zero terminated) value, while <content>
-represents a 32-bit value, specified in decimal or hexadecimal (the
-latter prefixed 0x). The various nodes in this example will be
-discussed in a later chapter. At this point, it is only meant to give
-you a idea of what a device-tree looks like. I have purposefully kept
-the "name" and "linux,phandle" properties which aren't necessary in
-order to give you a better idea of what the tree looks like in
-practice::
-
- / o device-tree
- |- name = "device-tree"
- |- model = "MyBoardName"
- |- compatible = "MyBoardFamilyName"
- |- #address-cells = <2>
- |- #size-cells = <2>
- |- linux,phandle = <0>
- |
- o cpus
- | | - name = "cpus"
- | | - linux,phandle = <1>
- | | - #address-cells = <1>
- | | - #size-cells = <0>
- | |
- | o PowerPC,970@0
- | |- name = "PowerPC,970"
- | |- device_type = "cpu"
- | |- reg = <0>
- | |- clock-frequency = <0x5f5e1000>
- | |- 64-bit
- | |- linux,phandle = <2>
- |
- o memory@0
- | |- name = "memory"
- | |- device_type = "memory"
- | |- reg = <0x00000000 0x00000000 0x00000000 0x20000000>
- | |- linux,phandle = <3>
- |
- o chosen
- |- name = "chosen"
- |- bootargs = "root=/dev/sda2"
- |- linux,phandle = <4>
-
-This tree is almost a minimal tree. It pretty much contains the
-minimal set of required nodes and properties to boot a linux kernel;
-that is, some basic model information at the root, the CPUs, and the
-physical memory layout. It also includes misc information passed
-through /chosen, like in this example, the platform type (mandatory)
-and the kernel command line arguments (optional).
-
-The /cpus/PowerPC,970@0/64-bit property is an example of a
-property without a value. All other properties have a value. The
-significance of the #address-cells and #size-cells properties will be
-explained in chapter IV which defines precisely the required nodes and
-properties and their content.
-
-
-3) Device tree "structure" block
---------------------------------
-
-The structure of the device tree is a linearized tree structure. The
-"OF_DT_BEGIN_NODE" token starts a new node, and the "OF_DT_END_NODE"
-ends that node definition. Child nodes are simply defined before
-"OF_DT_END_NODE" (that is nodes within the node). A 'token' is a 32
-bit value. The tree has to be "finished" with a OF_DT_END token
-
-Here's the basic structure of a single node:
-
- * token OF_DT_BEGIN_NODE (that is 0x00000001)
- * for version 1 to 3, this is the node full path as a zero
- terminated string, starting with "/". For version 16 and later,
- this is the node unit name only (or an empty string for the
- root node)
- * [align gap to next 4 bytes boundary]
- * for each property:
-
- * token OF_DT_PROP (that is 0x00000003)
- * 32-bit value of property value size in bytes (or 0 if no
- value)
- * 32-bit value of offset in string block of property name
- * property value data if any
- * [align gap to next 4 bytes boundary]
-
- * [child nodes if any]
- * token OF_DT_END_NODE (that is 0x00000002)
-
-So the node content can be summarized as a start token, a full path,
-a list of properties, a list of child nodes, and an end token. Every
-child node is a full node structure itself as defined above.
-
-NOTE: The above definition requires that all property definitions for
-a particular node MUST precede any subnode definitions for that node.
-Although the structure would not be ambiguous if properties and
-subnodes were intermingled, the kernel parser requires that the
-properties come first (up until at least 2.6.22). Any tools
-manipulating a flattened tree must take care to preserve this
-constraint.
-
-4) Device tree "strings" block
-------------------------------
-
-In order to save space, property names, which are generally redundant,
-are stored separately in the "strings" block. This block is simply the
-whole bunch of zero terminated strings for all property names
-concatenated together. The device-tree property definitions in the
-structure block will contain offset values from the beginning of the
-strings block.
-
-
-III - Required content of the device tree
-=========================================
-
-.. Warning::
-
- All ``linux,*`` properties defined in this document apply only
- to a flattened device-tree. If your platform uses a real
- implementation of Open Firmware or an implementation compatible with
- the Open Firmware client interface, those properties will be created
- by the trampoline code in the kernel's prom_init() file. For example,
- that's where you'll have to add code to detect your board model and
- set the platform number. However, when using the flattened device-tree
- entry point, there is no prom_init() pass, and thus you have to
- provide those properties yourself.
-
-
-1) Note about cells and address representation
-----------------------------------------------
-
-The general rule is documented in the various Open Firmware
-documentations. If you choose to describe a bus with the device-tree
-and there exist an OF bus binding, then you should follow the
-specification. However, the kernel does not require every single
-device or bus to be described by the device tree.
-
-In general, the format of an address for a device is defined by the
-parent bus type, based on the #address-cells and #size-cells
-properties. Note that the parent's parent definitions of #address-cells
-and #size-cells are not inherited so every node with children must specify
-them. The kernel requires the root node to have those properties defining
-addresses format for devices directly mapped on the processor bus.
-
-Those 2 properties define 'cells' for representing an address and a
-size. A "cell" is a 32-bit number. For example, if both contain 2
-like the example tree given above, then an address and a size are both
-composed of 2 cells, and each is a 64-bit number (cells are
-concatenated and expected to be in big endian format). Another example
-is the way Apple firmware defines them, with 2 cells for an address
-and one cell for a size. Most 32-bit implementations should define
-#address-cells and #size-cells to 1, which represents a 32-bit value.
-Some 32-bit processors allow for physical addresses greater than 32
-bits; these processors should define #address-cells as 2.
-
-"reg" properties are always a tuple of the type "address size" where
-the number of cells of address and size is specified by the bus
-#address-cells and #size-cells. When a bus supports various address
-spaces and other flags relative to a given address allocation (like
-prefetchable, etc...) those flags are usually added to the top level
-bits of the physical address. For example, a PCI physical address is
-made of 3 cells, the bottom two containing the actual address itself
-while the top cell contains address space indication, flags, and pci
-bus & device numbers.
-
-For buses that support dynamic allocation, it's the accepted practice
-to then not provide the address in "reg" (keep it 0) though while
-providing a flag indicating the address is dynamically allocated, and
-then, to provide a separate "assigned-addresses" property that
-contains the fully allocated addresses. See the PCI OF bindings for
-details.
-
-In general, a simple bus with no address space bits and no dynamic
-allocation is preferred if it reflects your hardware, as the existing
-kernel address parsing functions will work out of the box. If you
-define a bus type with a more complex address format, including things
-like address space bits, you'll have to add a bus translator to the
-prom_parse.c file of the recent kernels for your bus type.
-
-The "reg" property only defines addresses and sizes (if #size-cells is
-non-0) within a given bus. In order to translate addresses upward
-(that is into parent bus addresses, and possibly into CPU physical
-addresses), all buses must contain a "ranges" property. If the
-"ranges" property is missing at a given level, it's assumed that
-translation isn't possible, i.e., the registers are not visible on the
-parent bus. The format of the "ranges" property for a bus is a list
-of::
-
- bus address, parent bus address, size
-
-"bus address" is in the format of the bus this bus node is defining,
-that is, for a PCI bridge, it would be a PCI address. Thus, (bus
-address, size) defines a range of addresses for child devices. "parent
-bus address" is in the format of the parent bus of this bus. For
-example, for a PCI host controller, that would be a CPU address. For a
-PCI<->ISA bridge, that would be a PCI address. It defines the base
-address in the parent bus where the beginning of that range is mapped.
-
-For new 64-bit board support, I recommend either the 2/2 format or
-Apple's 2/1 format which is slightly more compact since sizes usually
-fit in a single 32-bit word. New 32-bit board support should use a
-1/1 format, unless the processor supports physical addresses greater
-than 32-bits, in which case a 2/1 format is recommended.
-
-Alternatively, the "ranges" property may be empty, indicating that the
-registers are visible on the parent bus using an identity mapping
-translation. In other words, the parent bus address space is the same
-as the child bus address space.
-
-2) Note about "compatible" properties
--------------------------------------
-
-These properties are optional, but recommended in devices and the root
-node. The format of a "compatible" property is a list of concatenated
-zero terminated strings. They allow a device to express its
-compatibility with a family of similar devices, in some cases,
-allowing a single driver to match against several devices regardless
-of their actual names.
-
-3) Note about "name" properties
--------------------------------
-
-While earlier users of Open Firmware like OldWorld macintoshes tended
-to use the actual device name for the "name" property, it's nowadays
-considered a good practice to use a name that is closer to the device
-class (often equal to device_type). For example, nowadays, Ethernet
-controllers are named "ethernet", an additional "model" property
-defining precisely the chip type/model, and "compatible" property
-defining the family in case a single driver can driver more than one
-of these chips. However, the kernel doesn't generally put any
-restriction on the "name" property; it is simply considered good
-practice to follow the standard and its evolutions as closely as
-possible.
-
-Note also that the new format version 16 makes the "name" property
-optional. If it's absent for a node, then the node's unit name is then
-used to reconstruct the name. That is, the part of the unit name
-before the "@" sign is used (or the entire unit name if no "@" sign
-is present).
-
-4) Note about node and property names and character set
--------------------------------------------------------
-
-While Open Firmware provides more flexible usage of 8859-1, this
-specification enforces more strict rules. Nodes and properties should
-be comprised only of ASCII characters 'a' to 'z', '0' to
-'9', ',', '.', '_', '+', '#', '?', and '-'. Node names additionally
-allow uppercase characters 'A' to 'Z' (property names should be
-lowercase. The fact that vendors like Apple don't respect this rule is
-irrelevant here). Additionally, node and property names should always
-begin with a character in the range 'a' to 'z' (or 'A' to 'Z' for node
-names).
-
-The maximum number of characters for both nodes and property names
-is 31. In the case of node names, this is only the leftmost part of
-a unit name (the pure "name" property), it doesn't include the unit
-address which can extend beyond that limit.
-
-
-5) Required nodes and properties
---------------------------------
- These are all that are currently required. However, it is strongly
- recommended that you expose PCI host bridges as documented in the
- PCI binding to Open Firmware, and your interrupt tree as documented
- in OF interrupt tree specification.
-
- a) The root node
-
- The root node requires some properties to be present:
-
- - model : this is your board name/model
- - #address-cells : address representation for "root" devices
- - #size-cells: the size representation for "root" devices
- - compatible : the board "family" generally finds its way here,
- for example, if you have 2 board models with a similar layout,
- that typically get driven by the same platform code in the
- kernel, you would specify the exact board model in the
- compatible property followed by an entry that represents the SoC
- model.
-
- The root node is also generally where you add additional properties
- specific to your board like the serial number if any, that sort of
- thing. It is recommended that if you add any "custom" property whose
- name may clash with standard defined ones, you prefix them with your
- vendor name and a comma.
-
- Additional properties for the root node:
-
- - serial-number : a string representing the device's serial number
-
- b) The /cpus node
-
- This node is the parent of all individual CPU nodes. It doesn't
- have any specific requirements, though it's generally good practice
- to have at least::
-
- #address-cells = <00000001>
- #size-cells = <00000000>
-
- This defines that the "address" for a CPU is a single cell, and has
- no meaningful size. This is not necessary but the kernel will assume
- that format when reading the "reg" properties of a CPU node, see
- below
-
- c) The ``/cpus/*`` nodes
-
- So under /cpus, you are supposed to create a node for every CPU on
- the machine. There is no specific restriction on the name of the
- CPU, though it's common to call it <architecture>,<core>. For
- example, Apple uses PowerPC,G5 while IBM uses PowerPC,970FX.
- However, the Generic Names convention suggests that it would be
- better to simply use 'cpu' for each cpu node and use the compatible
- property to identify the specific cpu core.
-
- Required properties:
-
- - device_type : has to be "cpu"
- - reg : This is the physical CPU number, it's a single 32-bit cell
- and is also used as-is as the unit number for constructing the
- unit name in the full path. For example, with 2 CPUs, you would
- have the full path::
-
- /cpus/PowerPC,970FX@0
- /cpus/PowerPC,970FX@1
-
- (unit addresses do not require leading zeroes)
- - d-cache-block-size : one cell, L1 data cache block size in bytes [#]_
- - i-cache-block-size : one cell, L1 instruction cache block size in
- bytes
- - d-cache-size : one cell, size of L1 data cache in bytes
- - i-cache-size : one cell, size of L1 instruction cache in bytes
-
- .. [#] The cache "block" size is the size on which the cache management
- instructions operate. Historically, this document used the cache
- "line" size here which is incorrect. The kernel will prefer the cache
- block size and will fallback to cache line size for backward
- compatibility.
-
- Recommended properties:
-
- - timebase-frequency : a cell indicating the frequency of the
- timebase in Hz. This is not directly used by the generic code,
- but you are welcome to copy/paste the pSeries code for setting
- the kernel timebase/decrementer calibration based on this
- value.
- - clock-frequency : a cell indicating the CPU core clock frequency
- in Hz. A new property will be defined for 64-bit values, but if
- your frequency is < 4Ghz, one cell is enough. Here as well as
- for the above, the common code doesn't use that property, but
- you are welcome to re-use the pSeries or Maple one. A future
- kernel version might provide a common function for this.
- - d-cache-line-size : one cell, L1 data cache line size in bytes
- if different from the block size
- - i-cache-line-size : one cell, L1 instruction cache line size in
- bytes if different from the block size
-
- You are welcome to add any property you find relevant to your board,
- like some information about the mechanism used to soft-reset the
- CPUs. For example, Apple puts the GPIO number for CPU soft reset
- lines in there as a "soft-reset" property since they start secondary
- CPUs by soft-resetting them.
-
-
- d) the /memory node(s)
-
- To define the physical memory layout of your board, you should
- create one or more memory node(s). You can either create a single
- node with all memory ranges in its reg property, or you can create
- several nodes, as you wish. The unit address (@ part) used for the
- full path is the address of the first range of memory defined by a
- given node. If you use a single memory node, this will typically be
- @0.
-
- Required properties:
-
- - device_type : has to be "memory"
- - reg : This property contains all the physical memory ranges of
- your board. It's a list of addresses/sizes concatenated
- together, with the number of cells of each defined by the
- #address-cells and #size-cells of the root node. For example,
- with both of these properties being 2 like in the example given
- earlier, a 970 based machine with 6Gb of RAM could typically
- have a "reg" property here that looks like::
-
- 00000000 00000000 00000000 80000000
- 00000001 00000000 00000001 00000000
-
- That is a range starting at 0 of 0x80000000 bytes and a range
- starting at 0x100000000 and of 0x100000000 bytes. You can see
- that there is no memory covering the IO hole between 2Gb and
- 4Gb. Some vendors prefer splitting those ranges into smaller
- segments, but the kernel doesn't care.
-
- Additional properties:
-
- - hotpluggable : The presence of this property provides an explicit
- hint to the operating system that this memory may potentially be
- removed later. The kernel can take this into consideration when
- doing nonmovable allocations and when laying out memory zones.
-
- e) The /chosen node
-
- This node is a bit "special". Normally, that's where Open Firmware
- puts some variable environment information, like the arguments, or
- the default input/output devices.
-
- This specification makes a few of these mandatory, but also defines
- some linux-specific properties that would be normally constructed by
- the prom_init() trampoline when booting with an OF client interface,
- but that you have to provide yourself when using the flattened format.
-
- Recommended properties:
-
- - bootargs : This zero-terminated string is passed as the kernel
- command line
- - linux,stdout-path : This is the full path to your standard
- console device if any. Typically, if you have serial devices on
- your board, you may want to put the full path to the one set as
- the default console in the firmware here, for the kernel to pick
- it up as its own default console.
-
- Note that u-boot creates and fills in the chosen node for platforms
- that use it.
-
- (Note: a practice that is now obsolete was to include a property
- under /chosen called interrupt-controller which had a phandle value
- that pointed to the main interrupt controller)
-
- f) the /soc<SOCname> node
-
- This node is used to represent a system-on-a-chip (SoC) and must be
- present if the processor is a SoC. The top-level soc node contains
- information that is global to all devices on the SoC. The node name
- should contain a unit address for the SoC, which is the base address
- of the memory-mapped register set for the SoC. The name of an SoC
- node should start with "soc", and the remainder of the name should
- represent the part number for the soc. For example, the MPC8540's
- soc node would be called "soc8540".
-
- Required properties:
-
- - ranges : Should be defined as specified in 1) to describe the
- translation of SoC addresses for memory mapped SoC registers.
- - bus-frequency: Contains the bus frequency for the SoC node.
- Typically, the value of this field is filled in by the boot
- loader.
- - compatible : Exact model of the SoC
-
-
- Recommended properties:
-
- - reg : This property defines the address and size of the
- memory-mapped registers that are used for the SOC node itself.
- It does not include the child device registers - these will be
- defined inside each child node. The address specified in the
- "reg" property should match the unit address of the SOC node.
- - #address-cells : Address representation for "soc" devices. The
- format of this field may vary depending on whether or not the
- device registers are memory mapped. For memory mapped
- registers, this field represents the number of cells needed to
- represent the address of the registers. For SOCs that do not
- use MMIO, a special address format should be defined that
- contains enough cells to represent the required information.
- See 1) above for more details on defining #address-cells.
- - #size-cells : Size representation for "soc" devices
- - #interrupt-cells : Defines the width of cells used to represent
- interrupts. Typically this value is <2>, which includes a
- 32-bit number that represents the interrupt number, and a
- 32-bit number that represents the interrupt sense and level.
- This field is only needed if the SOC contains an interrupt
- controller.
-
- The SOC node may contain child nodes for each SOC device that the
- platform uses. Nodes should not be created for devices which exist
- on the SOC but are not used by a particular platform. See chapter VI
- for more information on how to specify devices that are part of a SOC.
-
- Example SOC node for the MPC8540::
-
- soc8540@e0000000 {
- #address-cells = <1>;
- #size-cells = <1>;
- #interrupt-cells = <2>;
- device_type = "soc";
- ranges = <0x00000000 0xe0000000 0x00100000>
- reg = <0xe0000000 0x00003000>;
- bus-frequency = <0>;
- }

-
-IV - "dtc", the device tree compiler
-====================================
-
-
-dtc source code can be found at
-<http://git.jdl.com/gitweb/?p=dtc.git>
-
-.. Warning::
-
- This version is still in early development stage; the
- resulting device-tree "blobs" have not yet been validated with the
- kernel. The current generated block lacks a useful reserve map (it will
- be fixed to generate an empty one, it's up to the bootloader to fill
- it up) among others. The error handling needs work, bugs are lurking,
- etc...
-
-dtc basically takes a device-tree in a given format and outputs a
-device-tree in another format. The currently supported formats are:
-
-Input formats
--------------
-
- - "dtb": "blob" format, that is a flattened device-tree block
- with
- header all in a binary blob.
- - "dts": "source" format. This is a text file containing a
- "source" for a device-tree. The format is defined later in this
- chapter.
- - "fs" format. This is a representation equivalent to the
- output of /proc/device-tree, that is nodes are directories and
- properties are files
-
-Output formats
---------------
-
- - "dtb": "blob" format
- - "dts": "source" format
- - "asm": assembly language file. This is a file that can be
- sourced by gas to generate a device-tree "blob". That file can
- then simply be added to your Makefile. Additionally, the
- assembly file exports some symbols that can be used.
-
-
-The syntax of the dtc tool is::
-
- dtc [-I <input-format>] [-O <output-format>]
- [-o output-filename] [-V output_version] input_filename
-
-
-The "output_version" defines what version of the "blob" format will be
-generated. Supported versions are 1,2,3 and 16. The default is
-currently version 3 but that may change in the future to version 16.
-
-Additionally, dtc performs various sanity checks on the tree, like the
-uniqueness of linux, phandle properties, validity of strings, etc...
-
-The format of the .dts "source" file is "C" like, supports C and C++
-style comments::
-
- / {
- }
-
-The above is the "device-tree" definition. It's the only statement
-supported currently at the toplevel.
-
-::
-
- / {
- property1 = "string_value"; /* define a property containing a 0
- * terminated string
- */
-
- property2 = <0x1234abcd>; /* define a property containing a
- * numerical 32-bit value (hexadecimal)
- */
-
- property3 = <0x12345678 0x12345678 0xdeadbeef>;
- /* define a property containing 3
- * numerical 32-bit values (cells) in
- * hexadecimal
- */
- property4 = [0x0a 0x0b 0x0c 0x0d 0xde 0xea 0xad 0xbe 0xef];
- /* define a property whose content is
- * an arbitrary array of bytes
- */
-
- childnode@address { /* define a child node named "childnode"
- * whose unit name is "childnode at
- * address"
- */
-
- childprop = "hello\n"; /* define a property "childprop" of
- * childnode (in this case, a string)
- */
- };
- };
-
-Nodes can contain other nodes etc... thus defining the hierarchical
-structure of the tree.
-
-Strings support common escape sequences from C: "\n", "\t", "\r",
-"\(octal value)", "\x(hex value)".
-
-It is also suggested that you pipe your source file through cpp (gcc
-preprocessor) so you can use #include's, #define for constants, etc...
-
-Finally, various options are planned but not yet implemented, like
-automatic generation of phandles, labels (exported to the asm file so
-you can point to a property content and change it easily from whatever
-you link the device-tree with), label or path instead of numeric value
-in some cells to "point" to a node (replaced by a phandle at compile
-time), export of reserve map address to the asm file, ability to
-specify reserve map content at compile time, etc...
-
-We may provide a .h include file with common definitions of that
-proves useful for some properties (like building PCI properties or
-interrupt maps) though it may be better to add a notion of struct
-definitions to the compiler...
-
-
-V - Recommendations for a bootloader
-====================================
-
-
-Here are some various ideas/recommendations that have been proposed
-while all this has been defined and implemented.
-
- - The bootloader may want to be able to use the device-tree itself
- and may want to manipulate it (to add/edit some properties,
- like physical memory size or kernel arguments). At this point, 2
- choices can be made. Either the bootloader works directly on the
- flattened format, or the bootloader has its own internal tree
- representation with pointers (similar to the kernel one) and
- re-flattens the tree when booting the kernel. The former is a bit
- more difficult to edit/modify, the later requires probably a bit
- more code to handle the tree structure. Note that the structure
- format has been designed so it's relatively easy to "insert"
- properties or nodes or delete them by just memmoving things
- around. It contains no internal offsets or pointers for this
- purpose.
-
- - An example of code for iterating nodes & retrieving properties
- directly from the flattened tree format can be found in the kernel
- file drivers/of/fdt.c. Look at the of_scan_flat_dt() function,
- its usage in early_init_devtree(), and the corresponding various
- early_init_dt_scan_*() callbacks. That code can be re-used in a
- GPL bootloader, and as the author of that code, I would be happy
- to discuss possible free licensing to any vendor who wishes to
- integrate all or part of this code into a non-GPL bootloader.
- (reference needed; who is 'I' here? ---gcl Jan 31, 2011)
-
-
-
-VI - System-on-a-chip devices and nodes
-=======================================
-
-Many companies are now starting to develop system-on-a-chip
-processors, where the processor core (CPU) and many peripheral devices
-exist on a single piece of silicon. For these SOCs, an SOC node
-should be used that defines child nodes for the devices that make
-up the SOC. While platforms are not required to use this model in
-order to boot the kernel, it is highly encouraged that all SOC
-implementations define as complete a flat-device-tree as possible to
-describe the devices on the SOC. This will allow for the
-genericization of much of the kernel code.
-
-
-1) Defining child nodes of an SOC
----------------------------------
-
-Each device that is part of an SOC may have its own node entry inside
-the SOC node. For each device that is included in the SOC, the unit
-address property represents the address offset for this device's
-memory-mapped registers in the parent's address space. The parent's
-address space is defined by the "ranges" property in the top-level soc
-node. The "reg" property for each node that exists directly under the
-SOC node should contain the address mapping from the child address space
-to the parent SOC address space and the size of the device's
-memory-mapped register file.
-
-For many devices that may exist inside an SOC, there are predefined
-specifications for the format of the device tree node. All SOC child
-nodes should follow these specifications, except where noted in this
-document.
-
-See appendix A for an example partial SOC node definition for the
-MPC8540.
-
-
-2) Representing devices without a current OF specification
-----------------------------------------------------------
-
-Currently, there are many devices on SoCs that do not have a standard
-representation defined as part of the Open Firmware specifications,
-mainly because the boards that contain these SoCs are not currently
-booted using Open Firmware. Binding documentation for new devices
-should be added to the Documentation/devicetree/bindings directory.
-That directory will expand as device tree support is added to more and
-more SoCs.
-
-
-VII - Specifying interrupt information for devices
-===================================================
-
-The device tree represents the buses and devices of a hardware
-system in a form similar to the physical bus topology of the
-hardware.
-
-In addition, a logical 'interrupt tree' exists which represents the
-hierarchy and routing of interrupts in the hardware.
-
-The interrupt tree model is fully described in the
-document "Open Firmware Recommended Practice: Interrupt
-Mapping Version 0.9". The document is available at:
-<http://www.devicetree.org/open-firmware/practice/>
-
-1) interrupts property
-----------------------
-
-Devices that generate interrupts to a single interrupt controller
-should use the conventional OF representation described in the
-OF interrupt mapping documentation.
-
-Each device which generates interrupts must have an 'interrupt'
-property. The interrupt property value is an arbitrary number of
-of 'interrupt specifier' values which describe the interrupt or
-interrupts for the device.
-
-The encoding of an interrupt specifier is determined by the
-interrupt domain in which the device is located in the
-interrupt tree. The root of an interrupt domain specifies in
-its #interrupt-cells property the number of 32-bit cells
-required to encode an interrupt specifier. See the OF interrupt
-mapping documentation for a detailed description of domains.
-
-For example, the binding for the OpenPIC interrupt controller
-specifies an #interrupt-cells value of 2 to encode the interrupt
-number and level/sense information. All interrupt children in an
-OpenPIC interrupt domain use 2 cells per interrupt in their interrupts
-property.
-
-The PCI bus binding specifies a #interrupt-cells value of 1 to encode
-which interrupt pin (INTA,INTB,INTC,INTD) is used.
-
-2) interrupt-parent property
-----------------------------
-
-The interrupt-parent property is specified to define an explicit
-link between a device node and its interrupt parent in
-the interrupt tree. The value of interrupt-parent is the
-phandle of the parent node.
-
-If the interrupt-parent property is not defined for a node, its
-interrupt parent is assumed to be an ancestor in the node's
-*device tree* hierarchy.
-
-3) OpenPIC Interrupt Controllers
---------------------------------
-
-OpenPIC interrupt controllers require 2 cells to encode
-interrupt information. The first cell defines the interrupt
-number. The second cell defines the sense and level
-information.
-
-Sense and level information should be encoded as follows:
-
- == ========================================
- 0 low to high edge sensitive type enabled
- 1 active low level sensitive type enabled
- 2 active high level sensitive type enabled
- 3 high to low edge sensitive type enabled
- == ========================================
-
-4) ISA Interrupt Controllers
-----------------------------
-
-ISA PIC interrupt controllers require 2 cells to encode
-interrupt information. The first cell defines the interrupt
-number. The second cell defines the sense and level
-information.
-
-ISA PIC interrupt controllers should adhere to the ISA PIC
-encodings listed below:
-
- == ========================================
- 0 active low level sensitive type enabled
- 1 active high level sensitive type enabled
- 2 high to low edge sensitive type enabled
- 3 low to high edge sensitive type enabled
- == ========================================
-
-VIII - Specifying Device Power Management Information (sleep property)
-======================================================================
-
-Devices on SOCs often have mechanisms for placing devices into low-power
-states that are decoupled from the devices' own register blocks. Sometimes,
-this information is more complicated than a cell-index property can
-reasonably describe. Thus, each device controlled in such a manner
-may contain a "sleep" property which describes these connections.
-
-The sleep property consists of one or more sleep resources, each of
-which consists of a phandle to a sleep controller, followed by a
-controller-specific sleep specifier of zero or more cells.
-
-The semantics of what type of low power modes are possible are defined
-by the sleep controller. Some examples of the types of low power modes
-that may be supported are:
-
- - Dynamic: The device may be disabled or enabled at any time.
- - System Suspend: The device may request to be disabled or remain
- awake during system suspend, but will not be disabled until then.
- - Permanent: The device is disabled permanently (until the next hard
- reset).
-
-Some devices may share a clock domain with each other, such that they should
-only be suspended when none of the devices are in use. Where reasonable,
-such nodes should be placed on a virtual bus, where the bus has the sleep
-property. If the clock domain is shared among devices that cannot be
-reasonably grouped in this manner, then create a virtual sleep controller
-(similar to an interrupt nexus, except that defining a standardized
-sleep-map should wait until its necessity is demonstrated).
-
-IX - Specifying dma bus information
-===================================
-
-Some devices may have DMA memory range shifted relatively to the beginning of
-RAM, or even placed outside of kernel RAM. For example, the Keystone 2 SoC
-worked in LPAE mode with 4G memory has:
-- RAM range: [0x8 0000 0000, 0x8 FFFF FFFF]
-- DMA range: [ 0x8000 0000, 0xFFFF FFFF]
-and DMA range is aliased into first 2G of RAM in HW.
-
-In such cases, DMA addresses translation should be performed between CPU phys
-and DMA addresses. The "dma-ranges" property is intended to be used
-for describing the configuration of such system in DT.
-
-In addition, each DMA master device on the DMA bus may or may not support
-coherent DMA operations. The "dma-coherent" property is intended to be used
-for identifying devices supported coherent DMA operations in DT.
-
-* DMA Bus master
-
-Optional property:
-
-- dma-ranges: <prop-encoded-array> encoded as arbitrary number of triplets of
- (child-bus-address, parent-bus-address, length). Each triplet specified
- describes a contiguous DMA address range.
- The dma-ranges property is used to describe the direct memory access (DMA)
- structure of a memory-mapped bus whose device tree parent can be accessed
- from DMA operations originating from the bus. It provides a means of
- defining a mapping or translation between the physical address space of
- the bus and the physical address space of the parent of the bus.
- (for more information see the Devicetree Specification)
-
-* DMA Bus child
-
-Optional property:
-
-- dma-ranges: <empty> value. if present - It means that DMA addresses
- translation has to be enabled for this device.
-- dma-coherent: Present if dma operations are coherent
-
-Example::
-
- soc {
- compatible = "ti,keystone","simple-bus";
- ranges = <0x0 0x0 0x0 0xc0000000>;
- dma-ranges = <0x80000000 0x8 0x00000000 0x80000000>;
-
- [...]
-
- usb: usb@2680000 {
- compatible = "ti,keystone-dwc3";
-
- [...]
- dma-coherent;
- };
- };

-Device connections
-==================

-Introduction
-------------
-
-Devices often have connections to other devices that are outside of the direct
-child/parent relationship. A serial or network communication controller, which
-could be a PCI device, may need to be able to get a reference to its PHY
-component, which could be attached for example to the I2C bus. Some device
-drivers need to be able to control the clocks or the GPIOs for their devices,
-and so on.
-
-Device connections are generic descriptions of any type of connection between
-two separate devices.
-
-Device connections alone do not create a dependency between the two devices.
-They are only descriptions which are not tied to either of the devices directly.
-A dependency between the two devices exists only if one of the two endpoint
-devices requests a reference to the other. The descriptions themselves can be
-defined in firmware (not yet supported) or they can be built-in.
-
-Usage
------
-
-Device connections should exist before device ``->probe`` callback is called for
-either endpoint device in the description. If the connections are defined in
-firmware, this is not a problem. It should be considered if the connection
-descriptions are "built-in", and need to be added separately.
-
-The connection description consists of the names of the two devices with the
-connection, i.e. the endpoints, and unique identifier for the connection which
-is needed if there are multiple connections between the two devices.
-
-After a description exists, the devices in it can request reference to the other
-endpoint device, or they can request the description itself.

+Writing camera sensor drivers
+=============================
+
+CSI-2
+-----
+
+Please see what is written on :ref:`MIPI_CSI_2`.
+
+Handling clocks
+---------------
+
+Camera sensors have an internal clock tree including a PLL and a number of
+divisors. The clock tree is generally configured by the driver based on a few
+input parameters that are specific to the hardware:: the external clock frequency
+and the link frequency. The two parameters generally are obtained from system
+firmware. No other frequencies should be used in any circumstances.
+
+The reason why the clock frequencies are so important is that the clock signals
+come out of the SoC, and in many cases a specific frequency is designed to be
+used in the system. Using another frequency may cause harmful effects
+elsewhere. Therefore only the pre-determined frequencies are configurable by the
+user.
+
+Frame size
+----------
+
+There are two distinct ways to configure the frame size produced by camera
+sensors.
+
+Freely configurable camera sensor drivers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Freely configurable camera sensor drivers expose the device's internal
+processing pipeline as one or more sub-devices with different cropping and
+scaling configurations. The output size of the device is the result of a series
+of cropping and scaling operations from the device's pixel array's size.
+
+An example of such a driver is the smiapp driver (see drivers/media/i2c/smiapp).
+
+Register list based drivers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Register list based drivers generally, instead of able to configure the device
+they control based on user requests, are limited to a number of preset
+configurations that combine a number of different parameters that on hardware
+level are independent. How a driver picks such configuration is based on the
+format set on a source pad at the end of the device's internal pipeline.
+
+Most sensor drivers are implemented this way, see e.g.
+drivers/media/i2c/imx319.c for an example.
+
+Frame interval configuration
+----------------------------
+
+There are two different methods for obtaining possibilities for different frame
+intervals as well as configuring the frame interval. Which one to implement
+depends on the type of the device.
+
+Raw camera sensors
+~~~~~~~~~~~~~~~~~~
+
+Instead of a high level parameter such as frame interval, the frame interval is
+a result of the configuration of a number of camera sensor implementation
+specific parameters. Luckily, these parameters tend to be the same for more or
+less all modern raw camera sensors.
+
+The frame interval is calculated using the following equation::
+
+ frame interval = (analogue crop width + horizontal blanking) *
+ (analogue crop height + vertical blanking) / pixel rate
+
+The formula is bus independent and is applicable for raw timing parameters on
+large variety of devices beyond camera sensors. Devices that have no analogue
+crop, use the full source image size, i.e. pixel array size.
+
+Horizontal and vertical blanking are specified by ``V4L2_CID_HBLANK`` and
+``V4L2_CID_VBLANK``, respectively. The unit of these controls are lines. The
+pixel rate is specified by ``V4L2_CID_PIXEL_RATE`` in the same sub-device. The
+unit of that control is Hz.
+
+Register list based drivers need to implement read-only sub-device nodes for the
+purpose. Devices that are not register list based need these to configure the
+device's internal processing pipeline.
+
+The first entity in the linear pipeline is the pixel array. The pixel array may
+be followed by other entities that are there to allow configuring binning,
+skipping, scaling or digital crop :ref:`v4l2-subdev-selections`.
+
+USB cameras etc. devices
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+USB video class hardware, as well as many cameras offering a similar higher
+level interface natively, generally use the concept of frame interval (or frame
+rate) on device level in firmware or hardware. This means lower level controls
+implemented by raw cameras may not be used on uAPI (or even kAPI) to control the
+frame interval on these devices.
+
+Power management
+----------------
+
+Always use runtime PM to manage the power states of your device. Camera sensor
+drivers are in no way special in this respect: they are responsible for
+controlling the power state of the device they otherwise control as well. In
+general, the device must be powered on at least when its registers are being
+accessed and when it is streaming.
+
+Existing camera sensor drivers may rely on the old
+:c:type:`v4l2_subdev_core_ops`->s_power() callback for bridge or ISP drivers to
+manage their power state. This is however **deprecated**. If you feel you need
+to begin calling an s_power from an ISP or a bridge driver, instead please add
+runtime PM support to the sensor driver you are using. Likewise, new drivers
+should not use s_power.
+
+Please see examples in e.g. ``drivers/media/i2c/ov8856.c`` and
+``drivers/media/i2c/smiapp/smiapp-core.c``. The two drivers work in both ACPI
+and DT based systems.
+
+Control framework
+~~~~~~~~~~~~~~~~~
+
+``v4l2_ctrl_handler_setup()`` function may not be used in the device's runtime
+PM ``runtime_resume`` callback, as it has no way to figure out the power state
+of the device. This is because the power state of the device is only changed
+after the power state transition has taken place. The ``s_ctrl`` callback can be
+used to obtain device's power state after the power state transition:
+
+.. c:function::
+ int pm_runtime_get_if_in_use(struct device *dev);
+
+The function returns a non-zero value if it succeeded getting the power count or
+runtime PM was disabled, in either of which cases the driver may proceed to
+access the device.

+================================
+vidtv: Virtual Digital TV driver
+================================
+
+Author: Daniel W. S. Almeida <dwlsalmeida@gmail.com>, June 2020.
+
+Background
+----------
+
+Vidtv is a virtual DVB driver that aims to serve as a reference for driver
+writers by serving as a template. It also validates the existing media DVB
+APIs, thus helping userspace application writers.
+
+Currently, it consists of:
+
+- A fake tuner driver, which will report a bad signal quality if the chosen
+ frequency is too far away from a table of valid frequencies for a
+ particular delivery system.
+
+- A fake demod driver, which will constantly poll the fake signal quality
+ returned by the tuner, simulating a device that can lose/reacquire a lock
+ on the signal depending on the CNR levels.
+
+- A fake bridge driver, which is the module responsible for modprobing the
+ fake tuner and demod modules and implementing the demux logic. This module
+ takes parameters at initialization that will dictate how the simulation
+ behaves.
+
+- Code reponsible for encoding a valid MPEG Transport Stream, which is then
+ passed to the bridge driver. This fake stream contains some hardcoded content.
+ For now, we have a single, audio-only channel containing a single MPEG
+ Elementary Stream, which in turn contains a SMPTE 302m encoded sine-wave.
+ Note that this particular encoder was chosen because it is the easiest
+ way to encode PCM audio data in a MPEG Transport Stream.
+
+Building vidtv
+--------------
+vidtv is a test driver and thus is **not** enabled by default when
+compiling the kernel.
+
+In order to enable compilation of vidtv:
+
+- Enable **DVB_TEST_DRIVERS**, then
+- Enable **DVB_VIDTV**
+
+When compiled as a module, expect the following .ko files:
+
+- dvb_vidtv_tuner.ko
+
+- dvb_vidtv_demod.ko
+
+- dvb_vidtv_bridge.ko
+
+Running vidtv
+-------------
+When compiled as a module, run::
+
+ modprobe vidtv
+
+That's it! The bridge driver will initialize the tuner and demod drivers as
+part of its own initialization.
+
+By default, it will accept the following frequencies:
+
+ - 474 MHz for DVB-T/T2/C;
+ - 11,362 GHz for DVB-S/S2.
+
+For satellite systems, the driver simulates an universal extended
+LNBf, with frequencies at Ku-Band, ranging from 10.7 GHz to 12.75 GHz.
+
+You can optionally define some command-line arguments to vidtv.
+
+Command-line arguments to vidtv
+-------------------------------
+Below is a list of all arguments that can be supplied to vidtv:
+
+drop_tslock_prob_on_low_snr
+ Probability of losing the TS lock if the signal quality is bad.
+ This probability be used by the fake demodulator driver to
+ eventually return a status of 0 when the signal quality is not
+ good.
+
+recover_tslock_prob_on_good_snr:
+ Probability recovering the TS lock when the signal improves. This
+ probability be used by the fake demodulator driver to eventually
+ return a status of 0x1f when/if the signal quality improves.
+
+mock_power_up_delay_msec
+ Simulate a power up delay. Default: 0.
+
+mock_tune_delay_msec
+ Simulate a tune delay. Default 0.
+
+vidtv_valid_dvb_t_freqs
+ Valid DVB-T frequencies to simulate, in Hz.
+
+vidtv_valid_dvb_c_freqs
+ Valid DVB-C frequencies to simulate, in Hz.
+
+vidtv_valid_dvb_s_freqs
+ Valid DVB-S/S2 frequencies to simulate at Ku-Band, in kHz.
+
+max_frequency_shift_hz,
+ Maximum shift in HZ allowed when tuning in a channel.
+
+si_period_msec
+ How often to send SI packets. Default: 40ms.
+
+pcr_period_msec
+ How often to send PCR packets. Default: 40ms.
+
+mux_rate_kbytes_sec
+ Attempt to maintain this bit rate by inserting TS null packets, if
+ necessary. Default: 4096.
+
+pcr_pid,
+ PCR PID for all channels. Default: 0x200.
+
+mux_buf_sz_pkts,
+ Size for the mux buffer in multiples of 188 bytes.
+
+vidtv internal structure
+------------------------
+The kernel modules are split in the following way:
+
+vidtv_tuner.[ch]
+ Implements a fake tuner DVB driver.
+
+vidtv_demod.[ch]
+ Implements a fake demodulator DVB driver.
+
+vidtv_bridge.[ch]
+ Implements a bridge driver.
+
+The MPEG related code is split in the following way:
+
+vidtv_ts.[ch]
+ Code to work with MPEG TS packets, such as TS headers, adaptation
+ fields, PCR packets and NULL packets.
+
+vidtv_psi.[ch]
+ This is the PSI generator. PSI packets contain general information
+ about a MPEG Transport Stream. A PSI generator is needed so
+ userspace apps can retrieve information about the Transport Stream
+ and eventually tune into a (dummy) channel.
+
+ Because the generator is implemented in a separate file, it can be
+ reused elsewhere in the media subsystem.
+
+ Currently vidtv supports working with 3 PSI tables: PAT, PMT and
+ SDT.
+
+ The specification for PAT and PMT can be found in *ISO 13818-1:
+ Systems*, while the specification for the SDT can be found in *ETSI
+ EN 300 468: Specification for Service Information (SI) in DVB
+ systems*.
+
+ It isn't strictly necessary, but using a real TS file helps when
+ debugging PSI tables. Vidtv currently tries to replicate the PSI
+ structure found in this file: `TS1Globo.ts
+ <https://tsduck.io/streams/brazil-isdb-tb/TS1globo.ts>`_.
+
+ A good way to visualize the structure of streams is by using
+ `DVBInspector <https://sourceforge.net/projects/dvbinspector/>`_.
+
+vidtv_pes.[ch]
+ Implements the PES logic to convert encoder data into MPEG TS
+ packets. These can then be fed into a TS multiplexer and eventually
+ into userspace.
+
+vidtv_encoder.h
+ An interface for vidtv encoders. New encoders can be added to this
+ driver by implementing the calls in this file.
+
+vidtv_s302m.[ch]
+ Implements a S302M encoder to make it possible to insert PCM audio
+ data in the generated MPEG Transport Stream. The relevant
+ specification is available online as *SMPTE 302M-2007: Television -
+ Mapping of AES3 Data into MPEG-2 Transport Stream*.
+
+
+ The resulting MPEG Elementary Stream is conveyed in a private
+ stream with a S302M registration descriptor attached.
+
+ This shall enable passing an audio signal into userspace so it can
+ be decoded and played by media software. The corresponding decoder
+ in ffmpeg is located in 'libavcodec/s302m.c' and is experimental.
+
+vidtv_channel.[ch]
+ Implements a 'channel' abstraction.
+
+ When vidtv boots, it will create some hardcoded channels:
+
+ #. Their services will be concatenated to populate the SDT.
+
+ #. Their programs will be concatenated to populate the PAT
+
+ #. For each program in the PAT, a PMT section will be created
+
+ #. The PMT section for a channel will be assigned its streams.
+
+ #. Every stream will have its corresponding encoder polled in a
+ loop to produce TS packets.
+ These packets may be interleaved by the muxer and then delivered
+ to the bridge.
+
+vidtv_mux.[ch]
+ Implements a MPEG TS mux, loosely based on the ffmpeg
+ implementation in "libavcodec/mpegtsenc.c"
+
+ The muxer runs a loop which is responsible for:
+
+ #. Keeping track of the amount of time elapsed since the last
+ iteration.
+
+ #. Polling encoders in order to fetch 'elapsed_time' worth of data.
+
+ #. Inserting PSI and/or PCR packets, if needed.
+
+ #. Padding the resulting stream with NULL packets if
+ necessary in order to maintain the chosen bit rate.
+
+ #. Delivering the resulting TS packets to the bridge
+ driver so it can pass them to the demux.
+
+Testing vidtv with v4l-utils
+----------------------------
+
+Using the tools in v4l-utils is a great way to test and inspect the output of
+vidtv. It is hosted here: `v4l-utils Documentation
+<https://linuxtv.org/wiki/index.php/V4l-utils>`_.
+
+From its webpage::
+
+ The v4l-utils are a series of packages for handling media devices.
+
+ It is hosted at http://git.linuxtv.org/v4l-utils.git, and packaged
+ on most distributions.
+
+ It provides a series of libraries and utilities to be used to
+ control several aspect of the media boards.
+
+
+Start by installing v4l-utils and then modprobing vidtv::
+
+ modprobe dvb_vidtv_bridge
+
+If the driver is OK, it should load and its probing code will run. This will
+pull in the tuner and demod drivers.

+The first step to check whether the demod loaded successfully is to run::
+
+ $ dvb-fe-tool
+
+This should return what is currently set up at the demod struct, i.e.::

+ static const struct dvb_frontend_ops vidtv_demod_ops = {
+ .delsys = {
+ SYS_DVBT,
+ SYS_DVBT2,
+ SYS_DVBC_ANNEX_A,
+ SYS_DVBS,
+ SYS_DVBS2,
+ },
+
+ .info = {
+ .name = "Dummy demod for DVB-T/T2/C/S/S2",
+ .frequency_min_hz = 51 * MHz,
+ .frequency_max_hz = 2150 * MHz,
+ .frequency_stepsize_hz = 62500,
+ .frequency_tolerance_hz = 29500 * kHz,
+ .symbol_rate_min = 1000000,

+
+Using dvb-scan
+~~~~~~~~~~~~~~
+
+In order to tune into a channel and read the PSI tables, we can use dvb-scan.
+
+For this, one should provide a configuration file known as a 'scan file',
+here's an example::
+
+ [Channel]
+ FREQUENCY = 330000000
+ MODULATION = QAM/AUTO
+ SYMBOL_RATE = 6940000
+ INNER_FEC = AUTO
+ DELIVERY_SYSTEM = DVBC/ANNEX_A
+
+.. note::
+ The parameters depend on the video standard you're testing.
+
+.. note::
+ Vidtv is a fake driver and does not validate much of the information
+ in the scan file. Just specifying 'FREQUENCY' and 'DELIVERY_SYSTEM'
+ should be enough for DVB-T/DVB-T2. For DVB-S/DVB-C however, you
+ should also provide 'SYMBOL_RATE'.
+
+You can browse scan tables online here: `dvb-scan-tables
+<https://git.linuxtv.org/dtv-scan-tables.git>`_.
+
+Assuming this channel is named 'channel.conf', you can then run::
+
+ $ dvbv5-scan channel.conf
+
+For more information on dvb-scan, check its documentation online here:
+`dvb-scan Documentation <https://www.linuxtv.org/wiki/index.php/Dvbscan>`_.
+
+Using dvb-zap
+~~~~~~~~~~~~~
+
+dvbv5-zap is a command line tool that can be used to record MPEG-TS to disk. The
+typical use is to tune into a channel and put it into record mode. The example
+below - which is taken from the documentation - illustrates that::
+
+ $ dvbv5-zap -c dvb_channel.conf "trilhas sonoras" -r
+ using demux '/dev/dvb/adapter0/demux0'
+ reading channels from file 'dvb_channel.conf'
+ service has pid type 05: 204
+ tuning to 573000000 Hz
+ audio pid 104
+ dvb_set_pesfilter 104
+ Lock (0x1f) Quality= Good Signal= 100.00% C/N= -13.80dB UCB= 70 postBER= 3.14x10^-3 PER= 0
+ DVR interface '/dev/dvb/adapter0/dvr0' can now be opened
+
+The channel can be watched by playing the contents of the DVR interface, with
+some player that recognizes the MPEG-TS format, such as *mplayer* or *vlc*.
+
+By playing the contents of the stream one can visually inspect the workings of
+vidtv, e.g.::
+
+ $ mplayer /dev/dvb/adapter0/dvr0
+
+For more information on dvb-zap check its online documentation here:
+`dvb-zap Documentation
+<https://www.linuxtv.org/wiki/index.php/Dvbv5-zap>`_.
+See also: `zap <https://www.linuxtv.org/wiki/index.php/Zap>`_.
+
+
+What can still be improved in vidtv
+-----------------------------------
+
+Add *debugfs* integration
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Although frontend drivers provide DVBv5 statistics via the .read_status
+call, a nice addition would be to make additional statistics available to
+userspace via debugfs, which is a simple-to-use, RAM-based filesystem
+specifically designed for debug purposes.
+
+The logic for this would be implemented on a separate file so as not to
+pollute the frontend driver. These statistics are driver-specific and can
+be useful during tests.
+
+The Siano driver is one example of a driver using
+debugfs to convey driver-specific statistics to userspace and it can be
+used as a reference.
+
+This should be further enabled and disabled via a Kconfig
+option for convenience.
+
+Add a way to test video
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Currently, vidtv can only encode PCM audio. It would be great to implement
+a barebones version of MPEG-2 video encoding so we can also test video. The
+first place to look into is *ISO 13818-2: Information technology — Generic
+coding of moving pictures and associated audio information — Part 2: Video*,
+which covers the encoding of compressed video in MPEG Transport Streams.
+
+This might optionally use the Video4Linux2 Test Pattern Generator, v4l2-tpg,
+which resides at::
+
+ drivers/media/common/v4l2-tpg/
+
+
+Add white noise simulation
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The vidtv tuner already has code to identify whether the chosen frequency
+is too far away from a table of valid frequencies. For now, this means that
+the demodulator can eventually lose the lock on the signal, since the tuner will
+report a bad signal quality.
+
+A nice addition is to simulate some noise when the signal quality is bad by:
+
+- Randomly dropping some TS packets. This will trigger a continuity error if the
+ continuity counter is updated but the packet is not passed on to the demux.
+
+- Updating the error statistics accordingly (e.g. BER, etc).
+
+- Simulating some noise in the encoded data.

+1.1 What the TV decoder can do an what not
+------------------------------------------
+
+The best know TV standards are NTSC/PAL/SECAM. but for decoding a frame that
+information is not enough. There are several formats of the TV standards.
+And not every TV decoder is able to handle every format. Also the every
+combination is supported by the driver. There are currently 11 different
+tv broadcast formats all aver the world.
+
+The CCIR defines parameters needed for broadcasting the signal.
+The CCIR has defined different standards: A,B,D,E,F,G,D,H,I,K,K1,L,M,N,...
+The CCIR says not much about the colorsystem used !!!
+And talking about a colorsystem says not to much about how it is broadcast.
+
+The CCIR standards A,E,F are not used any more.
+
+When you speak about NTSC, you usually mean the standard: CCIR - M using
+the NTSC colorsystem which is used in the USA, Japan, Mexico, Canada
+and a few others.
+
+When you talk about PAL, you usually mean: CCIR - B/G using the PAL
+colorsystem which is used in many Countries.
+
+When you talk about SECAM, you mean: CCIR - L using the SECAM Colorsystem
+which is used in France, and a few others.
+
+There the other version of SECAM, CCIR - D/K is used in Bulgaria, China,
+Slovakai, Hungary, Korea (Rep.), Poland, Rumania and a others.
+
+The CCIR - H uses the PAL colorsystem (sometimes SECAM) and is used in
+Egypt, Libya, Sri Lanka, Syrain Arab. Rep.
+
+The CCIR - I uses the PAL colorsystem, and is used in Great Britain, Hong Kong,
+Ireland, Nigeria, South Africa.
+
+The CCIR - N uses the PAL colorsystem and PAL frame size but the NTSC framerate,
+and is used in Argentinia, Uruguay, an a few others
+
+We do not talk about how the audio is broadcast !
+
+A rather good sites about the TV standards are:
+http://www.sony.jp/support/
+http://info.electronicwerkstatt.de/bereiche/fernsehtechnik/frequenzen_und_normen/Fernsehnormen/
+and http://www.cabl.com/restaurant/channel.html
+
+Other weird things around: NTSC 4.43 is a modificated NTSC, which is mainly
+used in PAL VCR's that are able to play back NTSC. PAL 60 seems to be the same
+as NTSC 4.43 . The Datasheets also talk about NTSC 44, It seems as if it would
+be the same as NTSC 4.43.
+NTSC Combs seems to be a decoder mode where the decoder uses a comb filter
+to split coma and luma instead of a Delay line.
+
+But I did not defiantly find out what NTSC Comb is.

+--------------------------------------
+
+The TV encoder is doing the "same" as the decoder, but in the other direction.
+You feed them digital data and the generate a Composite or SVHS signal.

+The adv717x, should be able to produce PAL N. But you find nothing PAL N
+specific in the registers. Seem that you have to reuse a other standard
+to generate PAL N, maybe it would work if you use the PAL M settings.
+
+How do I get this damn thing to work
+------------------------------------
+
+Load zr36067.o. If it can't autodetect your card, use the card=X insmod
+option with X being the card number as given in the previous section.
+To have more than one card, use card=X1[,X2[,X3,[X4[..]]]]
+
+To automate this, add the following to your /etc/modprobe.d/zoran.conf:
+
+options zr36067 card=X1[,X2[,X3[,X4[..]]]]
+alias char-major-81-0 zr36067
+
+One thing to keep in mind is that this doesn't load zr36067.o itself yet. It
+just automates loading. If you start using xawtv, the device won't load on
+some systems, since you're trying to load modules as a user, which is not
+allowed ("permission denied"). A quick workaround is to add 'Load "v4l"' to
+XF86Config-4 when you use X by default, or to run 'v4l-conf -c <device>' in
+one of your startup scripts (normally rc.local) if you don't use X. Both
+make sure that the modules are loaded on startup, under the root account.
+
+What mainboard should I use (or why doesn't my card work)
+---------------------------------------------------------
+
+
+<insert lousy disclaimer here>. In short: good=SiS/Intel, bad=VIA.
+
+Experience tells us that people with a Buz, on average, have more problems
+than users with a DC10+/LML33. Also, it tells us that people owning a VIA-
+based mainboard (ktXXX, MVP3) have more problems than users with a mainboard
+based on a different chipset. Here's some notes from Andrew Stevens:
+
+Here's my experience of using LML33 and Buz on various motherboards:
+
+- VIA MVP3
+ - Forget it. Pointless. Doesn't work.
+- Intel 430FX (Pentium 200)
+ - LML33 perfect, Buz tolerable (3 or 4 frames dropped per movie)
+- Intel 440BX (early stepping)
+ - LML33 tolerable. Buz starting to get annoying (6-10 frames/hour)
+- Intel 440BX (late stepping)
+ - Buz tolerable, LML3 almost perfect (occasional single frame drops)
+- SiS735
+ - LML33 perfect, Buz tolerable.
+- VIA KT133(*)
+ - LML33 starting to get annoying, Buz poor enough that I have up.
+
+- Both 440BX boards were dual CPU versions.
+
+Bernhard Praschinger later added:
+
+- AMD 751
+ - Buz perfect-tolerable
+- AMD 760
+ - Buz perfect-tolerable
+
+In general, people on the user mailinglist won't give you much of a chance
+if you have a VIA-based motherboard. They may be cheap, but sometimes, you'd
+rather want to spend some more money on better boards. In general, VIA
+mainboard's IDE/PCI performance will also suck badly compared to others.
+You'll noticed the DC10+/DC30+ aren't mentioned anywhere in the overview.
+Basically, you can assume that if the Buz works, the LML33 will work too. If
+the LML33 works, the DC10+/DC30+ will work too. They're most tolerant to
+different mainboard chipsets from all of the supported cards.
+
+If you experience timeouts during capture, buy a better mainboard or lower
+the quality/buffersize during capture (see 'Concerning buffer sizes, quality,
+output size etc.'). If it hangs, there's little we can do as of now. Check
+your IRQs and make sure the card has its own interrupts.
+
+Programming interface
+---------------------
+
+This driver conforms to video4linux2. Support for V4L1 and for the custom
+zoran ioctls has been removed in kernel 2.6.38.
+
+For programming example, please, look at lavrec.c and lavplay.c code in
+the MJPEG-tools (http://mjpeg.sf.net/).
+
+Additional notes for software developers:
+
+ The driver returns maxwidth and maxheight parameters according to
+ the current TV standard (norm). Therefore, the software which
+ communicates with the driver and "asks" for these parameters should
+ first set the correct norm. Well, it seems logically correct: TV
+ standard is "more constant" for current country than geometry
+ settings of a variety of TV capture cards which may work in ITU or
+ square pixel format.
+
+Applications
+------------
+
+Applications known to work with this driver:
+
+TV viewing:
+
+* xawtv
+* kwintv
+* probably any TV application that supports video4linux or video4linux2.
+
+MJPEG capture/playback:
+
+* mjpegtools/lavtools (or Linux Video Studio)
+* gstreamer
+* mplayer
+
+General raw capture:
+
+* xawtv
+* gstreamer
+* probably any application that supports video4linux or video4linux2
+
+Video editing:
+
+* Cinelerra
+* MainActor
+* mjpegtools (or Linux Video Studio)
+
+
+Concerning buffer sizes, quality, output size etc.
+--------------------------------------------------
+
+
+The zr36060 can do 1:2 JPEG compression. This is really the theoretical
+maximum that the chipset can reach. The driver can, however, limit compression
+to a maximum (size) of 1:4. The reason for this is that some cards (e.g. Buz)
+can't handle 1:2 compression without stopping capture after only a few minutes.
+With 1:4, it'll mostly work. If you have a Buz, use 'low_bitrate=1' to go into
+1:4 max. compression mode.
+
+100% JPEG quality is thus 1:2 compression in practice. So for a full PAL frame
+(size 720x576). The JPEG fields are stored in YUY2 format, so the size of the
+fields are 720x288x16/2 bits/field (2 fields/frame) = 207360 bytes/field x 2 =
+414720 bytes/frame (add some more bytes for headers and DHT (huffman)/DQT
+(quantization) tables, and you'll get to something like 512kB per frame for
+1:2 compression. For 1:4 compression, you'd have frames of half this size.
+
+Some additional explanation by Martin Samuelsson, which also explains the
+importance of buffer sizes:
+--
+> Hmm, I do not think it is really that way. With the current (downloaded

+
+I woke up, and can't go to sleep again. I'll kill some time explaining why
+this doesn't look strange to me.
+
+Let's do some math using a width of 704 pixels. I'm not sure whether the Buz
+actually use that number or not, but that's not too important right now.
+
+704x288 pixels, one field, is 202752 pixels. Divided by 64 pixels per block;
+3168 blocks per field. Each pixel consist of two bytes; 128 bytes per block;
+1024 bits per block. 100% in the new driver mean 1:2 compression; the maximum
+output becomes 512 bits per block. Actually 510, but 512 is simpler to use
+for calculations.
+
+Let's say that we specify d1q50. We thus want 256 bits per block; times 3168
+becomes 811008 bits; 101376 bytes per field. We're talking raw bits and bytes
+here, so we don't need to do any fancy corrections for bits-per-pixel or such
+things. 101376 bytes per field.
+
+d1 video contains two fields per frame. Those sum up to 202752 bytes per
+frame, and one of those frames goes into each buffer.
+
+But wait a second! -b128 gives 128kB buffers! It's not possible to cram
+202752 bytes of JPEG data into 128kB!
+
+This is what the driver notice and automatically compensate for in your
+examples. Let's do some math using this information:
+
+128kB is 131072 bytes. In this buffer, we want to store two fields, which
+leaves 65536 bytes for each field. Using 3168 blocks per field, we get
+20.68686868... available bytes per block; 165 bits. We can't allow the
+request for 256 bits per block when there's only 165 bits available! The -q50
+option is silently overridden, and the -b128 option takes precedence, leaving
+us with the equivalence of -q32.
+
+This gives us a data rate of 165 bits per block, which, times 3168, sums up
+to 65340 bytes per field, out of the allowed 65536. The current driver has
+another level of rate limiting; it won't accept -q values that fill more than
+6/8 of the specified buffers. (I'm not sure why. "Playing it safe" seem to be
+a safe bet. Personally, I think I would have lowered requested-bits-per-block
+by one, or something like that.) We can't use 165 bits per block, but have to
+lower it again, to 6/8 of the available buffer space: We end up with 124 bits
+per block, the equivalence of -q24. With 128kB buffers, you can't use greater
+than -q24 at -d1. (And PAL, and 704 pixels width...)
+
+The third example is limited to -q24 through the same process. The second
+example, using very similar calculations, is limited to -q48. The only
+example that actually grab at the specified -q value is the last one, which
+is clearly visible, looking at the file size.
+--
+
+Conclusion: the quality of the resulting movie depends on buffer size, quality,
+whether or not you use 'low_bitrate=1' as insmod option for the zr36060.c
+module to do 1:4 instead of 1:2 compression, etc.
+
+If you experience timeouts, lowering the quality/buffersize or using
+'low_bitrate=1 as insmod option for zr36060.o might actually help, as is
+proven by the Buz.
+
+It hangs/crashes/fails/whatevers! Help!
+---------------------------------------
+
+Make sure that the card has its own interrupts (see /proc/interrupts), check
+the output of dmesg at high verbosity (load zr36067.o with debug=2,
+load all other modules with debug=1). Check that your mainboard is favorable
+(see question 2) and if not, test the card in another computer. Also see the
+notes given in question 3 and try lowering quality/buffersize/capturesize
+if recording fails after a period of time.
+
+If all this doesn't help, give a clear description of the problem including
+detailed hardware information (memory+brand, mainboard+chipset+brand, which
+MJPEG card, processor, other PCI cards that might be of interest), give the
+system PnP information (/proc/interrupts, /proc/dma, /proc/devices), and give
+the kernel version, driver version, glibc version, gcc version and any other
+information that might possibly be of interest. Also provide the dmesg output
+at high verbosity. See 'Contacting' on how to contact the developers.

+registered this way are stored in a global list of subdevices, ready to be
+picked up by bridge drivers.
+
+Bridge drivers in turn have to register a notifier object. This is

+Before registering the notifier, bridge drivers must do two things:

+
+The V4L2 core will then use these descriptors to match asynchronously
+registered subdevices to them. If a match is detected the ``.bound()``

-check for a master clock availability. If any of the conditions aren't satisfied
-the driver might decide to return ``-EPROBE_DEFER`` to request further reprobing
-attempts. Once all conditions are met the subdevice shall be registered using
-the :c:func:`v4l2_async_register_subdev` function. Unregistration is
-performed using the :c:func:`v4l2_async_unregister_subdev` call. Subdevices
-registered this way are stored in a global list of subdevices, ready to be
-picked up by bridge drivers.
-
-Bridge drivers in turn have to register a notifier object. This is
-performed using the :c:func:`v4l2_async_notifier_register` call. To
-unregister the notifier the driver has to call
-:c:func:`v4l2_async_notifier_unregister`. The former of the two functions
-takes two arguments: a pointer to struct :c:type:`v4l2_device` and a
-pointer to struct :c:type:`v4l2_async_notifier`.
-
-Before registering the notifier, bridge drivers must do two things:
-first, the notifier must be initialized using the
-:c:func:`v4l2_async_notifier_init`. Second, bridge drivers can then
-begin to form a list of subdevice descriptors that the bridge device
-needs for its operation. Subdevice descriptors are added to the notifier
-using the :c:func:`v4l2_async_notifier_add_subdev` call. This function
-takes two arguments: a pointer to struct :c:type:`v4l2_async_notifier`,
-and a pointer to the subdevice descripter, which is of type struct
-:c:type:`v4l2_async_subdev`.
-
-The V4L2 core will then use these descriptors to match asynchronously
-registered subdevices to them. If a match is detected the ``.bound()``
-notifier callback is called. After all subdevices have been located the
-.complete() callback is called. When a subdevice is removed from the
-system the .unbind() method is called. All three callbacks are optional.

+Fast commits
+~~~~~~~~~~~~
+
+JBD2 to also allows you to perform file-system specific delta commits known as
+fast commits. In order to use fast commits, you first need to call
+:c:func:`jbd2_fc_init` and tell how many blocks at the end of journal
+area should be reserved for fast commits. Along with that, you will also need
+to set following callbacks that perform correspodning work:
+
+`journal->j_fc_cleanup_cb`: Cleanup function called after every full commit and
+fast commit.
+
+`journal->j_fc_replay_cb`: Replay function called for replay of fast commit
+blocks.
+
+File system is free to perform fast commits as and when it wants as long as it
+gets permission from JBD2 to do so by calling the function
+:c:func:`jbd2_fc_begin_commit()`. Once a fast commit is done, the client
+file system should tell JBD2 about it by calling
+:c:func:`jbd2_fc_end_commit()`. If file system wants JBD2 to perform a full
+commit immediately after stopping the fast commit it can do so by calling
+:c:func:`jbd2_fc_end_commit_fallback()`. This is useful if fast commit operation
+fails for some reason and the only way to guarantee consistency is for JBD2 to
+perform the full traditional commit.
+
+JBD2 helper functions to manage fast commit buffers. File system can use
+:c:func:`jbd2_fc_get_buf()` and :c:func:`jbd2_fc_wait_bufs()` to allocate
+and wait on IO completion of fast commit buffers.
+
+Currently, only Ext4 implements fast commits. For details of its implementation
+of fast commits, please refer to the top level comments in
+fs/ext4/fast_commit.c.

+The advantage of mounting with the "volatile" option is that all forms of

cannot support render nodes.
+Device Hot-Unplug
+=================
+
+.. note::
+ The following is the plan. Implementation is not there yet
+ (2020 May).
+
+Graphics devices (display and/or render) may be connected via USB (e.g.
+display adapters or docking stations) or Thunderbolt (e.g. eGPU). An end
+user is able to hot-unplug this kind of devices while they are being
+used, and expects that the very least the machine does not crash. Any
+damage from hot-unplugging a DRM device needs to be limited as much as
+possible and userspace must be given the chance to handle it if it wants
+to. Ideally, unplugging a DRM device still lets a desktop continue to
+run, but that is going to need explicit support throughout the whole
+graphics stack: from kernel and userspace drivers, through display
+servers, via window system protocols, and in applications and libraries.
+
+Other scenarios that should lead to the same are: unrecoverable GPU
+crash, PCI device disappearing off the bus, or forced unbind of a driver
+from the physical device.
+
+In other words, from userspace perspective everything needs to keep on
+working more or less, until userspace stops using the disappeared DRM
+device and closes it completely. Userspace will learn of the device
+disappearance from the device removed uevent, ioctls returning ENODEV
+(or driver-specific ioctls returning driver-specific things), or open()
+returning ENXIO.
+
+Only after userspace has closed all relevant DRM device and dmabuf file
+descriptors and removed all mmaps, the DRM driver can tear down its
+instance for the device that no longer exists. If the same physical
+device somehow comes back in the mean time, it shall be a new DRM
+device.
+
+Similar to PIDs, chardev minor numbers are not recycled immediately. A
+new DRM device always picks the next free minor number compared to the
+previous one allocated, and wraps around when minor numbers are
+exhausted.
+
+The goal raises at least the following requirements for the kernel and
+drivers.
+
+Requirements for KMS UAPI
+-------------------------
+
+- KMS connectors must change their status to disconnected.
+
+- Legacy modesets and pageflips, and atomic commits, both real and
+ TEST_ONLY, and any other ioctls either fail with ENODEV or fake
+ success.
+
+- Pending non-blocking KMS operations deliver the DRM events userspace
+ is expecting. This applies also to ioctls that faked success.
+
+- open() on a device node whose underlying device has disappeared will
+ fail with ENXIO.
+
+- Attempting to create a DRM lease on a disappeared DRM device will
+ fail with ENODEV. Existing DRM leases remain and work as listed
+ above.
+
+Requirements for Render and Cross-Device UAPI
+---------------------------------------------
+
+- All GPU jobs that can no longer run must have their fences
+ force-signalled to avoid inflicting hangs on userspace.
+ The associated error code is ENODEV.
+
+- Some userspace APIs already define what should happen when the device
+ disappears (OpenGL, GL ES: `GL_KHR_robustness`_; `Vulkan`_:
+ VK_ERROR_DEVICE_LOST; etc.). DRM drivers are free to implement this
+ behaviour the way they see best, e.g. returning failures in
+ driver-specific ioctls and handling those in userspace drivers, or
+ rely on uevents, and so on.
+
+- dmabuf which point to memory that has disappeared will either fail to
+ import with ENODEV or continue to be successfully imported if it would
+ have succeeded before the disappearance. See also about memory maps
+ below for already imported dmabufs.
+
+- Attempting to import a dmabuf to a disappeared device will either fail
+ with ENODEV or succeed if it would have succeeded without the
+ disappearance.
+
+- open() on a device node whose underlying device has disappeared will
+ fail with ENXIO.
+
+.. _GL_KHR_robustness: https://www.khronos.org/registry/OpenGL/extensions/KHR/KHR_robustness.txt
+.. _Vulkan: https://www.khronos.org/vulkan/
+
+Requirements for Memory Maps
+----------------------------
+
+Memory maps have further requirements that apply to both existing maps
+and maps created after the device has disappeared. If the underlying
+memory disappears, the map is created or modified such that reads and
+writes will still complete successfully but the result is undefined.
+This applies to both userspace mmap()'d memory and memory pointed to by
+dmabuf which might be mapped to other devices (cross-device dmabuf
+imports).
+
+Raising SIGBUS is not an option, because userspace cannot realistically
+handle it. Signal handlers are global, which makes them extremely
+difficult to use correctly from libraries like those that Mesa produces.
+Signal handlers are not composable, you can't have different handlers
+for GPU1 and GPU2 from different vendors, and a third handler for
+mmapped regular files. Threads cause additional pain with signal
+handling as well.

+Plumb drm_atomic_state all over
+-------------------------------
+
+Currently various atomic functions take just a single or a handful of
+object states (eg. plane state). While that single object state can
+suffice for some simple cases, we often have to dig out additional
+object states for dealing with various dependencies between the individual
+objects or the hardware they represent. The process of digging out the
+additional states is rather non-intuitive and error prone.
+
+To fix that most functions should rather take the overall
+drm_atomic_state as one of their parameters. The other parameters
+would generally be the object(s) we mainly want to interact with.
+
+For example, instead of
+
+.. code-block:: c
+
+ int (*atomic_check)(struct drm_plane *plane, struct drm_plane_state *state);
+
+we would have something like
+
+.. code-block:: c
+
+ int (*atomic_check)(struct drm_plane *plane, struct drm_atomic_state *state);
+
+The implementation can then trivially gain access to any required object
+state(s) via drm_atomic_get_plane_state(), drm_atomic_get_new_plane_state(),
+drm_atomic_get_old_plane_state(), and their equivalents for
+other object types.
+
+Additionally many drivers currently access the object->state pointer
+directly in their commit functions. That is not going to work if we
+eg. want to allow deeper commit pipelines as those pointers could
+then point to the states corresponding to a future commit instead of
+the current commit we're trying to process. Also non-blocking commits
+execute locklessly so there are serious concerns with dereferencing
+the object->state pointers without holding the locks that protect them.
+Use of drm_atomic_get_new_plane_state(), drm_atomic_get_old_plane_state(),
+etc. avoids these problems as well since they relate to a specific
+commit via the passed in drm_atomic_state.

+Description
+-----------
+
+The sl28cpld is a board management controller which also exposes a hardware
+monitoring controller. At the moment this controller supports a single fan
+supervisor. In the future there might be other flavours and additional
+hardware monitoring might be supported.
+
+The fan supervisor has a 7 bit counter register and a counter period of 1
+second. If the 7 bit counter overflows, the supervisor will automatically
+switch to x8 mode to support a wider input range at the loss of
+granularity.
+

+================================
+Linux I2C slave testunit backend
+================================
+
+by Wolfram Sang <wsa@sang-engineering.com> in 2020
+
+This backend can be used to trigger test cases for I2C bus masters which
+require a remote device with certain capabilities (and which are usually not so
+easy to obtain). Examples include multi-master testing, and SMBus Host Notify
+testing. For some tests, the I2C slave controller must be able to switch
+between master and slave mode because it needs to send data, too.
+
+Note that this is a device for testing and debugging. It should not be enabled
+in a production build. And while there is some versioning and we try hard to
+keep backward compatibility, there is no stable ABI guaranteed!
+
+Instantiating the device is regular. Example for bus 0, address 0x30:
+
+# echo "slave-testunit 0x1030" > /sys/bus/i2c/devices/i2c-0/new_device
+
+After that, you will have a write-only device listening. Reads will just return
+an 8-bit version number of the testunit. When writing, the device consists of 4
+8-bit registers and all must be written to start a testcase, i.e. you must
+always write 4 bytes to the device. The registers are:
+
+0x00 CMD - which test to trigger
+0x01 DATAL - configuration byte 1 for the test
+0x02 DATAH - configuration byte 2 for the test
+0x03 DELAY - delay in n * 10ms until test is started
+
+Using 'i2cset' from the i2c-tools package, the generic command looks like:
+
+# i2cset -y <bus_num> <testunit_address> <CMD> <DATAL> <DATAH> <DELAY> i
+
+DELAY is a generic parameter which will delay the execution of the test in CMD.
+While a command is running (including the delay), new commands will not be
+acknowledged. You need to wait until the old one is completed.
+
+The commands are described in the following section. An invalid command will
+result in the transfer not being acknowledged.
+
+Commands
+--------
+
+0x00 NOOP (reserved for future use)
+
+0x01 READ_BYTES (also needs master mode)
+ DATAL - address to read data from (lower 7 bits, highest bit currently unused)
+ DATAH - number of bytes to read
+
+This is useful to test if your bus master driver is handling multi-master
+correctly. You can trigger the testunit to read bytes from another device on
+the bus. If the bus master under test also wants to access the bus at the same
+time, the bus will be busy. Example to read 128 bytes from device 0x50 after
+50ms of delay:
+
+# i2cset -y 0 0x30 0x01 0x50 0x80 0x05 i
+
+0x02 SMBUS_HOST_NOTIFY (also needs master mode)
+ DATAL - low byte of the status word to send
+ DATAH - high byte of the status word to send
+
+This test will send an SMBUS_HOST_NOTIFY message to the host. Note that the
+status word is currently ignored in the Linux Kernel. Example to send a
+notification after 10ms:
+
+# i2cset -y 0 0x30 0x02 0x42 0x64 0x01 i

-********************************************************
-Recipe for getting/building/running Xen/ia64 with pv_ops
-********************************************************
-This recipe describes how to get xen-ia64 source and build it,
-and run domU with pv_ops.
-
-Requirements
-============
-
- - python
- - mercurial
- it (aka "hg") is an open-source source code
- management software. See the below.
- http://www.selenic.com/mercurial/wiki/
- - git
- - bridge-utils
-
-Getting and Building Xen and Dom0
-=================================
-
- My environment is:
-
- - Machine : Tiger4
- - Domain0 OS : RHEL5
- - DomainU OS : RHEL5
-
- 1. Download source::
-
- # hg clone http://xenbits.xensource.com/ext/ia64/xen-unstable.hg
- # cd xen-unstable.hg
- # hg clone http://xenbits.xensource.com/ext/ia64/linux-2.6.18-xen.hg
-
- 2. # make world
-
- 3. # make install-tools
-
- 4. copy kernels and xen::
-
- # cp xen/xen.gz /boot/efi/efi/redhat/
- # cp build-linux-2.6.18-xen_ia64/vmlinux.gz \
- /boot/efi/efi/redhat/vmlinuz-2.6.18.8-xen
-
- 5. make initrd for Dom0/DomU::
-
- # make -C linux-2.6.18-xen.hg ARCH=ia64 modules_install \
- O=$(pwd)/build-linux-2.6.18-xen_ia64
- # mkinitrd -f /boot/efi/efi/redhat/initrd-2.6.18.8-xen.img \
- 2.6.18.8-xen --builtin mptspi --builtin mptbase \
- --builtin mptscsih --builtin uhci-hcd --builtin ohci-hcd \
- --builtin ehci-hcd
-
-Making a disk image for guest OS
-================================
-
- 1. make file::
-
- # dd if=/dev/zero of=/root/rhel5.img bs=1M seek=4096 count=0
- # mke2fs -F -j /root/rhel5.img
- # mount -o loop /root/rhel5.img /mnt
- # cp -ax /{dev,var,etc,usr,bin,sbin,lib} /mnt
- # mkdir /mnt/{root,proc,sys,home,tmp}
-
- Note: You may miss some device files. If so, please create them
- with mknod. Or you can use tar instead of cp.
-
- 2. modify DomU's fstab::
-
- # vi /mnt/etc/fstab
- /dev/xvda1 / ext3 defaults 1 1
- none /dev/pts devpts gid=5,mode=620 0 0
- none /dev/shm tmpfs defaults 0 0
- none /proc proc defaults 0 0
- none /sys sysfs defaults 0 0
-
- 3. modify inittab
-
- set runlevel to 3 to avoid X trying to start::
-
- # vi /mnt/etc/inittab
- id:3:initdefault:
-
- Start a getty on the hvc0 console::
-
- X0:2345:respawn:/sbin/mingetty hvc0
-
- tty1-6 mingetty can be commented out
-
- 4. add hvc0 into /etc/securetty::
-
- # vi /mnt/etc/securetty (add hvc0)
-
- 5. umount::
-
- # umount /mnt
-
-FYI, virt-manager can also make a disk image for guest OS.
-It's GUI tools and easy to make it.
-
-Boot Xen & Domain0
-==================
-
- 1. replace elilo
- elilo of RHEL5 can boot Xen and Dom0.
- If you use old elilo (e.g RHEL4), please download from the below
- http://elilo.sourceforge.net/cgi-bin/blosxom
- and copy into /boot/efi/efi/redhat/::
-
- # cp elilo-3.6-ia64.efi /boot/efi/efi/redhat/elilo.efi
-
- 2. modify elilo.conf (like the below)::
-
- # vi /boot/efi/efi/redhat/elilo.conf
- prompt
- timeout=20
- default=xen
- relocatable
-
- image=vmlinuz-2.6.18.8-xen
- label=xen
- vmm=xen.gz
- initrd=initrd-2.6.18.8-xen.img
- read-only
- append=" -- rhgb root=/dev/sda2"
-
-The append options before "--" are for xen hypervisor,
-the options after "--" are for dom0.
-
-FYI, your machine may need console options like
-"com1=19200,8n1 console=vga,com1". For example,
-append="com1=19200,8n1 console=vga,com1 -- rhgb console=tty0 \
-console=ttyS0 root=/dev/sda2"
-
-Getting and Building domU with pv_ops
-=====================================
-
- 1. get pv_ops tree::
-
- # git clone http://people.valinux.co.jp/~yamahata/xen-ia64/linux-2.6-xen-ia64.git/
-
- 2. git branch (if necessary)::
-
- # cd linux-2.6-xen-ia64/
- # git checkout -b your_branch origin/xen-ia64-domu-minimal-2008may19
-
- Note:
- The current branch is xen-ia64-domu-minimal-2008may19.
- But you would find the new branch. You can see with
- "git branch -r" to get the branch lists.
-
- http://people.valinux.co.jp/~yamahata/xen-ia64/for_eagl/linux-2.6-ia64-pv-ops.git/
-
- is also available.
-
- The tree is based on
-
- git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 test)
-
- 3. copy .config for pv_ops of domU::
-
- # cp arch/ia64/configs/xen_domu_wip_defconfig .config
-
- 4. make kernel with pv_ops::
-
- # make oldconfig
- # make
-
- 5. install the kernel and initrd::
-
- # cp vmlinux.gz /boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU
- # make modules_install
- # mkinitrd -f /boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img \
- 2.6.26-rc3xen-ia64-08941-g1b12161 --builtin mptspi \
- --builtin mptbase --builtin mptscsih --builtin uhci-hcd \
- --builtin ohci-hcd --builtin ehci-hcd
-
-Boot DomainU with pv_ops
-========================
-
- 1. make config of DomU::
-
- # vi /etc/xen/rhel5
- kernel = "/boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU"
- ramdisk = "/boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img"
- vcpus = 1
- memory = 512
- name = "rhel5"
- disk = [ 'file:/root/rhel5.img,xvda1,w' ]
- root = "/dev/xvda1 ro"
- extra= "rhgb console=hvc0"
-
- 2. After boot xen and dom0, start xend::
-
- # /etc/init.d/xend start
-
- ( In the debugging case, `# XEND_DEBUG=1 xend trace_start` )
-
- 3. start domU::
-
- # xm create -c rhel5

+Recursive read locks:
+---------------------
+The whole of the rest document tries to prove a certain type of cycle is equivalent
+to deadlock possibility.
+
+There are three types of lockers: writers (i.e. exclusive lockers, like
+spin_lock() or write_lock()), non-recursive readers (i.e. shared lockers, like
+down_read()) and recursive readers (recursive shared lockers, like rcu_read_lock()).
+And we use the following notations of those lockers in the rest of the document:
+
+ W or E: stands for writers (exclusive lockers).
+ r: stands for non-recursive readers.
+ R: stands for recursive readers.
+ S: stands for all readers (non-recursive + recursive), as both are shared lockers.
+ N: stands for writers and non-recursive readers, as both are not recursive.
+
+Obviously, N is "r or W" and S is "r or R".
+
+Recursive readers, as their name indicates, are the lockers allowed to acquire
+even inside the critical section of another reader of the same lock instance,
+in other words, allowing nested read-side critical sections of one lock instance.
+
+While non-recursive readers will cause a self deadlock if trying to acquire inside
+the critical section of another reader of the same lock instance.
+
+The difference between recursive readers and non-recursive readers is because:
+recursive readers get blocked only by a write lock *holder*, while non-recursive
+readers could get blocked by a write lock *waiter*. Considering the follow example:
+
+ TASK A: TASK B:
+
+ read_lock(X);
+ write_lock(X);
+ read_lock_2(X);
+
+Task A gets the reader (no matter whether recursive or non-recursive) on X via
+read_lock() first. And when task B tries to acquire writer on X, it will block
+and become a waiter for writer on X. Now if read_lock_2() is recursive readers,
+task A will make progress, because writer waiters don't block recursive readers,
+and there is no deadlock. However, if read_lock_2() is non-recursive readers,
+it will get blocked by writer waiter B, and cause a self deadlock.
+
+Block conditions on readers/writers of the same lock instance:
+--------------------------------------------------------------
+There are simply four block conditions:
+
+1. Writers block other writers.
+2. Readers block writers.
+3. Writers block both recursive readers and non-recursive readers.
+4. And readers (recursive or not) don't block other recursive readers but
+ may block non-recursive readers (because of the potential co-existing
+ writer waiters)
+
+Block condition matrix, Y means the row blocks the column, and N means otherwise.
+
+ | E | r | R |
+ +---+---+---+---+
+ E | Y | Y | Y |
+ +---+---+---+---+
+ r | Y | Y | N |
+ +---+---+---+---+
+ R | Y | Y | N |
+
+ (W: writers, r: non-recursive readers, R: recursive readers)
+
+
+acquired recursively. Unlike non-recursive read locks, recursive read locks
+only get blocked by current write lock *holders* other than write lock
+*waiters*, for example:
+
+ TASK A: TASK B:
+
+ read_lock(X);
+
+ write_lock(X);
+
+ read_lock(X);
+
+is not a deadlock for recursive read locks, as while the task B is waiting for
+the lock X, the second read_lock() doesn't need to wait because it's a recursive
+read lock. However if the read_lock() is non-recursive read lock, then the above
+case is a deadlock, because even if the write_lock() in TASK B cannot get the
+lock, but it can block the second read_lock() in TASK A.
+
+Note that a lock can be a write lock (exclusive lock), a non-recursive read
+lock (non-recursive shared lock) or a recursive read lock (recursive shared
+lock), depending on the lock operations used to acquire it (more specifically,
+the value of the 'read' parameter for lock_acquire()). In other words, a single
+lock instance has three types of acquisition depending on the acquisition
+functions: exclusive, non-recursive read, and recursive read.
+
+To be concise, we call that write locks and non-recursive read locks as
+"non-recursive" locks and recursive read locks as "recursive" locks.
+
+Recursive locks don't block each other, while non-recursive locks do (this is
+even true for two non-recursive read locks). A non-recursive lock can block the
+corresponding recursive lock, and vice versa.
+
+A deadlock case with recursive locks involved is as follow:
+
+ TASK A: TASK B:
+
+ read_lock(X);
+ read_lock(Y);
+ write_lock(Y);
+ write_lock(X);
+
+Task A is waiting for task B to read_unlock() Y and task B is waiting for task
+A to read_unlock() X.
+
+Dependency types and strong dependency paths:
+---------------------------------------------
+Lock dependencies record the orders of the acquisitions of a pair of locks, and
+because there are 3 types for lockers, there are, in theory, 9 types of lock
+dependencies, but we can show that 4 types of lock dependencies are enough for
+deadlock detection.
+
+For each lock dependency:
+
+ L1 -> L2
+
+, which means lockdep has seen L1 held before L2 held in the same context at runtime.
+And in deadlock detection, we care whether we could get blocked on L2 with L1 held,
+IOW, whether there is a locker L3 that L1 blocks L3 and L2 gets blocked by L3. So
+we only care about 1) what L1 blocks and 2) what blocks L2. As a result, we can combine
+recursive readers and non-recursive readers for L1 (as they block the same types) and
+we can combine writers and non-recursive readers for L2 (as they get blocked by the
+same types).
+
+With the above combination for simplification, there are 4 types of dependency edges
+in the lockdep graph:
+
+1) -(ER)->: exclusive writer to recursive reader dependency, "X -(ER)-> Y" means
+ X -> Y and X is a writer and Y is a recursive reader.
+
+2) -(EN)->: exclusive writer to non-recursive locker dependency, "X -(EN)-> Y" means
+ X -> Y and X is a writer and Y is either a writer or non-recursive reader.
+
+3) -(SR)->: shared reader to recursive reader dependency, "X -(SR)-> Y" means
+ X -> Y and X is a reader (recursive or not) and Y is a recursive reader.
+
+4) -(SN)->: shared reader to non-recursive locker dependency, "X -(SN)-> Y" means
+ X -> Y and X is a reader (recursive or not) and Y is either a writer or
+ non-recursive reader.
+
+Note that given two locks, they may have multiple dependencies between them, for example:
+
+ TASK A:
+
+ read_lock(X);
+ write_lock(Y);
+ ...
+
+ TASK B:
+
+ write_lock(X);
+ write_lock(Y);
+
+, we have both X -(SN)-> Y and X -(EN)-> Y in the dependency graph.
+
+We use -(xN)-> to represent edges that are either -(EN)-> or -(SN)->, the
+similar for -(Ex)->, -(xR)-> and -(Sx)->
+
+A "path" is a series of conjunct dependency edges in the graph. And we define a
+"strong" path, which indicates the strong dependency throughout each dependency
+in the path, as the path that doesn't have two conjunct edges (dependencies) as
+-(xR)-> and -(Sx)->. In other words, a "strong" path is a path from a lock
+walking to another through the lock dependencies, and if X -> Y -> Z is in the
+path (where X, Y, Z are locks), and the walk from X to Y is through a -(SR)-> or
+-(ER)-> dependency, the walk from Y to Z must not be through a -(SN)-> or
+-(SR)-> dependency.
+
+We will see why the path is called "strong" in next section.
+
+Recursive Read Deadlock Detection:
+----------------------------------
+
+We now prove two things:
+
+Lemma 1:
+
+If there is a closed strong path (i.e. a strong circle), then there is a
+combination of locking sequences that causes deadlock. I.e. a strong circle is
+sufficient for deadlock detection.
+
+Lemma 2:
+
+If there is no closed strong path (i.e. strong circle), then there is no
+combination of locking sequences that could cause deadlock. I.e. strong
+circles are necessary for deadlock detection.
+
+With these two Lemmas, we can easily say a closed strong path is both sufficient
+and necessary for deadlocks, therefore a closed strong path is equivalent to
+deadlock possibility. As a closed strong path stands for a dependency chain that
+could cause deadlocks, so we call it "strong", considering there are dependency
+circles that won't cause deadlocks.
+
+Proof for sufficiency (Lemma 1):
+
+Let's say we have a strong circle:
+
+ L1 -> L2 ... -> Ln -> L1
+
+, which means we have dependencies:
+
+ L1 -> L2
+ L2 -> L3
+ ...
+ Ln-1 -> Ln
+ Ln -> L1
+
+We now can construct a combination of locking sequences that cause deadlock:
+
+Firstly let's make one CPU/task get the L1 in L1 -> L2, and then another get
+the L2 in L2 -> L3, and so on. After this, all of the Lx in Lx -> Lx+1 are
+held by different CPU/tasks.
+
+And then because we have L1 -> L2, so the holder of L1 is going to acquire L2
+in L1 -> L2, however since L2 is already held by another CPU/task, plus L1 ->
+L2 and L2 -> L3 are not -(xR)-> and -(Sx)-> (the definition of strong), which
+means either L2 in L1 -> L2 is a non-recursive locker (blocked by anyone) or
+the L2 in L2 -> L3, is writer (blocking anyone), therefore the holder of L1
+cannot get L2, it has to wait L2's holder to release.
+
+Moreover, we can have a similar conclusion for L2's holder: it has to wait L3's
+holder to release, and so on. We now can prove that Lx's holder has to wait for
+Lx+1's holder to release, and note that Ln+1 is L1, so we have a circular
+waiting scenario and nobody can get progress, therefore a deadlock.
+
+Proof for necessary (Lemma 2):
+
+Lemma 2 is equivalent to: If there is a deadlock scenario, then there must be a
+strong circle in the dependency graph.
+
+According to Wikipedia[1], if there is a deadlock, then there must be a circular
+waiting scenario, means there are N CPU/tasks, where CPU/task P1 is waiting for
+a lock held by P2, and P2 is waiting for a lock held by P3, ... and Pn is waiting
+for a lock held by P1. Let's name the lock Px is waiting as Lx, so since P1 is waiting
+for L1 and holding Ln, so we will have Ln -> L1 in the dependency graph. Similarly,
+we have L1 -> L2, L2 -> L3, ..., Ln-1 -> Ln in the dependency graph, which means we
+have a circle:
+
+ Ln -> L1 -> L2 -> ... -> Ln
+
+, and now let's prove the circle is strong:
+
+For a lock Lx, Px contributes the dependency Lx-1 -> Lx and Px+1 contributes
+the dependency Lx -> Lx+1, and since Px is waiting for Px+1 to release Lx,
+so it's impossible that Lx on Px+1 is a reader and Lx on Px is a recursive
+reader, because readers (no matter recursive or not) don't block recursive
+readers, therefore Lx-1 -> Lx and Lx -> Lx+1 cannot be a -(xR)-> -(Sx)-> pair,
+and this is true for any lock in the circle, therefore, the circle is strong.

+Modifying Patches
+=================
+
+If you are a subsystem or branch maintainer, sometimes you need to slightly
+modify patches you receive in order to merge them, because the code is not
+exactly the same in your tree and the submitters'. If you stick strictly to
+rule (c) of the developers certificate of origin, you should ask the submitter
+to rediff, but this is a totally counter-productive waste of time and energy.
+Rule (b) allows you to adjust the code, but then it is very impolite to change
+one submitters code and make him endorse your bugs. To solve this problem, it
+is recommended that you add a line between the last Signed-off-by header and
+yours, indicating the nature of your changes. While there is nothing mandatory
+about this, it seems like prepending the description with your mail and/or
+name, all enclosed in square brackets, is noticeable enough to make it obvious
+that you are responsible for last-minute changes. Example::
+
+ Signed-off-by: Random J Developer <random@developer.example.org>
+ [lucky@maintainer.example.org: struct foo moved from foo.c to foo.h]
+ Signed-off-by: Lucky K Maintainer <lucky@maintainer.example.org>
+
+This practice is particularly helpful if you maintain a stable branch and
+want at the same time to credit the author, track changes, merge the fix,
+and protect the submitter from complaints. Note that under no circumstances
+can you change the author's identity (the From header), as it is the one
+which appears in the changelog.
+
+Special note to back-porters: It seems to be a common and useful practice
+to insert an indication of the origin of a patch at the top of the commit
+message (just after the subject line) to facilitate tracking. For instance,
+here's what we see in a 3.x-stable release::
+
+ Date: Tue Oct 7 07:26:38 2014 -0400
+
+ libata: Un-break ATA blacklist

+ commit 1c40279960bcd7d52dbdf1d466b20d24b99176c8 upstream.

-======================================================
-Intel Many Integrated Core (MIC) architecture overview
-======================================================
-
-An Intel MIC X100 device is a PCIe form factor add-in coprocessor
-card based on the Intel Many Integrated Core (MIC) architecture
-that runs a Linux OS. It is a PCIe endpoint in a platform and therefore
-implements the three required standard address spaces i.e. configuration,
-memory and I/O. The host OS loads a device driver as is typical for
-PCIe devices. The card itself runs a bootstrap after reset that
-transfers control to the card OS downloaded from the host driver. The
-host driver supports OSPM suspend and resume operations. It shuts down
-the card during suspend and reboots the card OS during resume.
-The card OS as shipped by Intel is a Linux kernel with modifications
-for the X100 devices.
-
-Since it is a PCIe card, it does not have the ability to host hardware
-devices for networking, storage and console. We provide these devices
-on X100 coprocessors thus enabling a self-bootable equivalent
-environment for applications. A key benefit of our solution is that it
-leverages the standard virtio framework for network, disk and console
-devices, though in our case the virtio framework is used across a PCIe
-bus. A Virtio Over PCIe (VOP) driver allows creating user space
-backends or devices on the host which are used to probe virtio drivers
-for these devices on the MIC card. The existing VRINGH infrastructure
-in the kernel is used to access virtio rings from the host. The card
-VOP driver allows card virtio drivers to communicate with their user
-space backends on the host via a device page. Ring 3 apps on the host
-can add, remove and configure virtio devices. A thin MIC specific
-virtio_config_ops is implemented which is borrowed heavily from
-previous similar implementations in lguest and s390.
-
-MIC PCIe card has a dma controller with 8 channels. These channels are
-shared between the host s/w and the card s/w. 0 to 3 are used by host
-and 4 to 7 by card. As the dma device doesn't show up as PCIe device,
-a virtual bus called mic bus is created and virtual dma devices are
-created on it by the host/card drivers. On host the channels are private
-and used only by the host driver to transfer data for the virtio devices.
-
-The Symmetric Communication Interface (SCIF (pronounced as skiff)) is a
-low level communications API across PCIe currently implemented for MIC.
-More details are available at scif_overview.txt.
-
-The Coprocessor State Management (COSM) driver on the host allows for
-boot, shutdown and reset of Intel MIC devices. It communicates with a COSM
-"client" driver on the MIC cards over SCIF to perform these functions.
-
-Here is a block diagram of the various components described above. The
-virtio backends are situated on the host rather than the card given better
-single threaded performance for the host compared to MIC, the ability of
-the host to initiate DMA's to/from the card using the MIC DMA engine and
-the fact that the virtio block storage backend can only be on the host::

-========================================
-Symmetric Communication Interface (SCIF)
-========================================
-
-The Symmetric Communication Interface (SCIF (pronounced as skiff)) is a low
-level communications API across PCIe currently implemented for MIC. Currently
-SCIF provides inter-node communication within a single host platform, where a
-node is a MIC Coprocessor or Xeon based host. SCIF abstracts the details of
-communicating over the PCIe bus while providing an API that is symmetric
-across all the nodes in the PCIe network. An important design objective for SCIF
-is to deliver the maximum possible performance given the communication
-abilities of the hardware. SCIF has been used to implement an offload compiler
-runtime and OFED support for MPI implementations for MIC coprocessors.
-
-SCIF API Components
-===================
-
-The SCIF API has the following parts:
-
-1. Connection establishment using a client server model
-2. Byte stream messaging intended for short messages
-3. Node enumeration to determine online nodes
-4. Poll semantics for detection of incoming connections and messages
-5. Memory registration to pin down pages
-6. Remote memory mapping for low latency CPU accesses via mmap
-7. Remote DMA (RDMA) for high bandwidth DMA transfers
-8. Fence APIs for RDMA synchronization
-
-SCIF exposes the notion of a connection which can be used by peer processes on
-nodes in a SCIF PCIe "network" to share memory "windows" and to communicate. A
-process in a SCIF node initiates a SCIF connection to a peer process on a
-different node via a SCIF "endpoint". SCIF endpoints support messaging APIs
-which are similar to connection oriented socket APIs. Connected SCIF endpoints
-can also register local memory which is followed by data transfer using either
-DMA, CPU copies or remote memory mapping via mmap. SCIF supports both user and
-kernel mode clients which are functionally equivalent.
-
-SCIF Performance for MIC
-========================
-
-DMA bandwidth comparison between the TCP (over ethernet over PCIe) stack versus
-SCIF shows the performance advantages of SCIF for HPC applications and
-runtimes::

- Transfer Size (KBytes)
-
-SCIF allows memory sharing via mmap(..) between processes on different PCIe
-nodes and thus provides bare-metal PCIe latency. The round trip SCIF mmap
-latency from the host to an x100 MIC for an 8 byte message is 0.44 usecs.
-
-SCIF has a user space library which is a thin IOCTL wrapper providing a user
-space API similar to the kernel API in scif.h. The SCIF user space library
-is distributed @ https://software.intel.com/en-us/mic-developer

-CAIF SPI porting
-================
-
-CAIF SPI basics
-===============
-
-Running CAIF over SPI needs some extra setup, owing to the nature of SPI.
-Two extra GPIOs have been added in order to negotiate the transfers
-between the master and the slave. The minimum requirement for running
-CAIF over SPI is a SPI slave chip and two GPIOs (more details below).
-Please note that running as a slave implies that you need to keep up
-with the master clock. An overrun or underrun event is fatal.
-
-CAIF SPI framework
-==================
-
-To make porting as easy as possible, the CAIF SPI has been divided in
-two parts. The first part (called the interface part) deals with all
-generic functionality such as length framing, SPI frame negotiation
-and SPI frame delivery and transmission. The other part is the CAIF
-SPI slave device part, which is the module that you have to write if
-you want to run SPI CAIF on a new hardware. This part takes care of
-the physical hardware, both with regard to SPI and to GPIOs.
-
-- Implementing a CAIF SPI device:
-
- - Functionality provided by the CAIF SPI slave device:
-
- In order to implement a SPI device you will, as a minimum,
- need to implement the following
- functions:
-
- ::
-
- int (*init_xfer) (struct cfspi_xfer * xfer, struct cfspi_dev *dev):
-
- This function is called by the CAIF SPI interface to give
- you a chance to set up your hardware to be ready to receive
- a stream of data from the master. The xfer structure contains
- both physical and logical addresses, as well as the total length
- of the transfer in both directions.The dev parameter can be used
- to map to different CAIF SPI slave devices.
-
- ::
-
- void (*sig_xfer) (bool xfer, struct cfspi_dev *dev):
-
- This function is called by the CAIF SPI interface when the output
- (SPI_INT) GPIO needs to change state. The boolean value of the xfer
- variable indicates whether the GPIO should be asserted (HIGH) or
- deasserted (LOW). The dev parameter can be used to map to different CAIF
- SPI slave devices.
-
- - Functionality provided by the CAIF SPI interface:
-
- ::
-
- void (*ss_cb) (bool assert, struct cfspi_ifc *ifc);
-
- This function is called by the CAIF SPI slave device in order to
- signal a change of state of the input GPIO (SS) to the interface.
- Only active edges are mandatory to be reported.
- This function can be called from IRQ context (recommended in order
- not to introduce latency). The ifc parameter should be the pointer
- returned from the platform probe function in the SPI device structure.
-
- ::
-
- void (*xfer_done_cb) (struct cfspi_ifc *ifc);
-
- This function is called by the CAIF SPI slave device in order to
- report that a transfer is completed. This function should only be
- called once both the transmission and the reception are completed.
- This function can be called from IRQ context (recommended in order
- not to introduce latency). The ifc parameter should be the pointer
- returned from the platform probe function in the SPI device structure.
-
- - Connecting the bits and pieces:
-
- - Filling in the SPI slave device structure:
-
- Connect the necessary callback functions.
-
- Indicate clock speed (used to calculate toggle delays).
-
- Chose a suitable name (helps debugging if you use several CAIF
- SPI slave devices).
-
- Assign your private data (can be used to map to your
- structure).
-
- - Filling in the SPI slave platform device structure:
-
- Add name of driver to connect to ("cfspi_sspi").
-
- Assign the SPI slave device structure as platform data.
-
-Padding
-=======
-
-In order to optimize throughput, a number of SPI padding options are provided.
-Padding can be enabled independently for uplink and downlink transfers.
-Padding can be enabled for the head, the tail and for the total frame size.
-The padding needs to be correctly configured on both sides of the link.
-The padding can be changed via module parameters in cfspi_sspi.c or via
-the sysfs directory of the cfspi_sspi driver (before device registration).

-EXHIBIT A
-
- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

+==============
+
+``devlink-reload`` provides mechanism to reinit driver entities, applying
+``devlink-params`` and ``devlink-resources`` new values. It also provides
+mechanism to activate firmware.
+
+Reload Actions
+==============

+ * - ``fw_activate``
+ - Firmware activate. Activates new firmware if such image is stored and
+ pending activation. If no limitation specified this action may involve
+ firmware reset. If no new image pending this action will reload current
+ firmware image.
+
+Note that even though user asks for a specific action, the driver
+implementation might require to perform another action alongside with
+it. For example, some driver do not support driver reinitialization
+being performed without fw activation. Therefore, the devlink reload
+command returns the list of actions which were actrually performed.
+
+Reload Limits
+=============
+
+By default reload actions are not limited and driver implementation may
+include reset or downtime as needed to perform the actions.

L2TP
====
-This document describes how to use the kernel's L2TP drivers to
-provide L2TP functionality. L2TP is a protocol that tunnels one or
-more sessions over an IP tunnel. It is commonly used for VPNs
-(L2TP/IPSec) and by ISPs to tunnel subscriber PPP sessions over an IP
-network infrastructure. With L2TPv3, it is also useful as a Layer-2
-tunneling infrastructure.
-
-Features
+Layer 2 Tunneling Protocol (L2TP) allows L2 frames to be tunneled over
+an IP network.
+
+This document covers the kernel's L2TP subsystem. It documents kernel
+APIs for application developers who want to use the L2TP subsystem and
+it provides some technical details about the internal implementation
+which may be useful to kernel developers and maintainers.
+
+Overview
========
-L2TPv2 (PPP over L2TP (UDP tunnels)).
-L2TPv3 ethernet pseudowires.
-L2TPv3 PPP pseudowires.
-L2TPv3 IP encapsulation.
-Netlink sockets for L2TPv3 configuration management.
-
-History
-=======
-
-The original pppol2tp driver was introduced in 2.6.23 and provided
-L2TPv2 functionality (rfc2661). L2TPv2 is used to tunnel one or more PPP
-sessions over a UDP tunnel.
-
-L2TPv3 (rfc3931) changes the protocol to allow different frame types
-to be passed over an L2TP tunnel by moving the PPP-specific parts of
-the protocol out of the core L2TP packet headers. Each frame type is
-known as a pseudowire type. Ethernet, PPP, HDLC, Frame Relay and ATM
-pseudowires for L2TP are defined in separate RFC standards. Another
-change for L2TPv3 is that it can be carried directly over IP with no
-UDP header (UDP is optional). It is also possible to create static
-unmanaged L2TPv3 tunnels manually without a control protocol
-(userspace daemon) to manage them.
-
-To support L2TPv3, the original pppol2tp driver was split up to
-separate the L2TP and PPP functionality. Existing L2TPv2 userspace
-apps should be unaffected as the original pppol2tp sockets API is
-retained. L2TPv3, however, uses netlink to manage L2TPv3 tunnels and
-sessions.
-
-Design
-======
-
-The L2TP protocol separates control and data frames. The L2TP kernel
-drivers handle only L2TP data frames; control frames are always
-handled by userspace. L2TP control frames carry messages between L2TP
-clients/servers and are used to setup / teardown tunnels and
-sessions. An L2TP client or server is implemented in userspace.
-
-Each L2TP tunnel is implemented using a UDP or L2TPIP socket; L2TPIP
-provides L2TPv3 IP encapsulation (no UDP) and is implemented using a
-new l2tpip socket family. The tunnel socket is typically created by
-userspace, though for unmanaged L2TPv3 tunnels, the socket can also be
-created by the kernel. Each L2TP session (pseudowire) gets a network
-interface instance. In the case of PPP, these interfaces are created
-indirectly by pppd using a pppol2tp socket. In the case of ethernet,
-the netdevice is created upon a netlink request to create an L2TPv3
-ethernet pseudowire.
-
-For PPP, the PPPoL2TP driver, net/l2tp/l2tp_ppp.c, provides a
-mechanism by which PPP frames carried through an L2TP session are
-passed through the kernel's PPP subsystem. The standard PPP daemon,
-pppd, handles all PPP interaction with the peer. PPP network
-interfaces are created for each local PPP endpoint. The kernel's PPP
-subsystem arranges for PPP control frames to be delivered to pppd,
-while data frames are forwarded as usual.
-
-For ethernet, the L2TPETH driver, net/l2tp/l2tp_eth.c, implements a
-netdevice driver, managing virtual ethernet devices, one per
-pseudowire. These interfaces can be managed using standard Linux tools
-such as "ip" and "ifconfig". If only IP frames are passed over the
-tunnel, the interface can be given an IP addresses of itself and its
-peer. If non-IP frames are to be passed over the tunnel, the interface
-can be added to a bridge using brctl. All L2TP datapath protocol
-functions are handled by the L2TP core driver.
-
-Each tunnel and session within a tunnel is assigned a unique tunnel_id
-and session_id. These ids are carried in the L2TP header of every
-control and data packet. (Actually, in L2TPv3, the tunnel_id isn't
-present in data frames - it is inferred from the IP connection on
-which the packet was received.) The L2TP driver uses the ids to lookup
-internal tunnel and/or session contexts to determine how to handle the
-packet. Zero tunnel / session ids are treated specially - zero ids are
-never assigned to tunnels or sessions in the network. In the driver,
-the tunnel context keeps a reference to the tunnel UDP or L2TPIP
-socket. The session context holds data that lets the driver interface
-to the kernel's network frame type subsystems, i.e. PPP, ethernet.
-
-Userspace Programming
-=====================
-
-For L2TPv2, there are a number of requirements on the userspace L2TP
-daemon in order to use the pppol2tp driver.
-
-1. Use a UDP socket per tunnel.
-
-2. Create a single PPPoL2TP socket per tunnel bound to a special null
- session id. This is used only for communicating with the driver but
- must remain open while the tunnel is active. Opening this tunnel
- management socket causes the driver to mark the tunnel socket as an
- L2TP UDP encapsulation socket and flags it for use by the
- referenced tunnel id. This hooks up the UDP receive path via
- udp_encap_rcv() in net/ipv4/udp.c. PPP data frames are never passed
- in this special PPPoX socket.
-
-3. Create a PPPoL2TP socket per L2TP session. This is typically done
- by starting pppd with the pppol2tp plugin and appropriate
- arguments. A PPPoL2TP tunnel management socket (Step 2) must be
- created before the first PPPoL2TP session socket is created.
+The kernel's L2TP subsystem implements the datapath for L2TPv2 and
+L2TPv3. L2TPv2 is carried over UDP. L2TPv3 is carried over UDP or
+directly over IP (protocol 115).
+
+The L2TP RFCs define two basic kinds of L2TP packets: control packets
+(the "control plane"), and data packets (the "data plane"). The kernel
+deals only with data packets. The more complex control packets are
+handled by user space.
+
+An L2TP tunnel carries one or more L2TP sessions. Each tunnel is
+associated with a socket. Each session is associated with a virtual
+netdevice, e.g. ``pppN``, ``l2tpethN``, through which data frames pass
+to/from L2TP. Fields in the L2TP header identify the tunnel or session
+and whether it is a control or data packet. When tunnels and sessions
+are set up using the Linux kernel API, we're just setting up the L2TP
+data path. All aspects of the control protocol are to be handled by
+user space.
+
+This split in responsibilities leads to a natural sequence of
+operations when establishing tunnels and sessions. The procedure looks
+like this:
+
+ 1) Create a tunnel socket. Exchange L2TP control protocol messages
+ with the peer over that socket in order to establish a tunnel.
+
+ 2) Create a tunnel context in the kernel, using information
+ obtained from the peer using the control protocol messages.
+
+ 3) Exchange L2TP control protocol messages with the peer over the
+ tunnel socket in order to establish a session.
+
+ 4) Create a session context in the kernel using information
+ obtained from the peer using the control protocol messages.
+
+L2TP APIs
+=========
+
+This section documents each userspace API of the L2TP subsystem.
+
+Tunnel Sockets
+--------------
+
+L2TPv2 always uses UDP. L2TPv3 may use UDP or IP encapsulation.
+
+To create a tunnel socket for use by L2TP, the standard POSIX
+socket API is used.
+
+For example, for a tunnel using IPv4 addresses and UDP encapsulation::
+
+ int sockfd = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);
+
+Or for a tunnel using IPv6 addresses and IP encapsulation::
+
+ int sockfd = socket(AF_INET6, SOCK_DGRAM, IPPROTO_L2TP);
+
+UDP socket programming doesn't need to be covered here.
+
+IPPROTO_L2TP is an IP protocol type implemented by the kernel's L2TP
+subsystem. The L2TPIP socket address is defined in struct
+sockaddr_l2tpip and struct sockaddr_l2tpip6 at
+`include/uapi/linux/l2tp.h`_. The address includes the L2TP tunnel
+(connection) id. To use L2TP IP encapsulation, an L2TPv3 application
+should bind the L2TPIP socket using the locally assigned
+tunnel id. When the peer's tunnel id and IP address is known, a
+connect must be done.
+
+If the L2TP application needs to handle L2TPv3 tunnel setup requests
+from peers using L2TPIP, it must open a dedicated L2TPIP
+socket to listen for those requests and bind the socket using tunnel
+id 0 since tunnel setup requests are addressed to tunnel id 0.
+
+An L2TP tunnel and all of its sessions are automatically closed when
+its tunnel socket is closed.
+
+Netlink API
+-----------
+
+L2TP applications use netlink to manage L2TP tunnel and session
+instances in the kernel. The L2TP netlink API is defined in
+`include/uapi/linux/l2tp.h`_.
+
+L2TP uses `Generic Netlink`_ (GENL). Several commands are defined:
+Create, Delete, Modify and Get for tunnel and session
+instances, e.g. ``L2TP_CMD_TUNNEL_CREATE``. The API header lists the
+netlink attribute types that can be used with each command.
+
+Tunnel and session instances are identified by a locally unique
+32-bit id. L2TP tunnel ids are given by ``L2TP_ATTR_CONN_ID`` and
+``L2TP_ATTR_PEER_CONN_ID`` attributes and L2TP session ids are given
+by ``L2TP_ATTR_SESSION_ID`` and ``L2TP_ATTR_PEER_SESSION_ID``
+attributes. If netlink is used to manage L2TPv2 tunnel and session
+instances, the L2TPv2 16-bit tunnel/session id is cast to a 32-bit
+value in these attributes.
+
+In the ``L2TP_CMD_TUNNEL_CREATE`` command, ``L2TP_ATTR_FD`` tells the
+kernel the tunnel socket fd being used. If not specified, the kernel
+creates a kernel socket for the tunnel, using IP parameters set in
+``L2TP_ATTR_IP[6]_SADDR``, ``L2TP_ATTR_IP[6]_DADDR``,
+``L2TP_ATTR_UDP_SPORT``, ``L2TP_ATTR_UDP_DPORT`` attributes. Kernel
+sockets are used to implement unmanaged L2TPv3 tunnels (iproute2's "ip
+l2tp" commands). If ``L2TP_ATTR_FD`` is given, it must be a socket fd
+that is already bound and connected. There is more information about
+unmanaged tunnels later in this document.

+PPPoL2TP Session Socket API
+---------------------------
+
+For PPP session types, a PPPoL2TP socket must be opened and connected
+to the L2TP session.
When creating PPPoL2TP sockets, the application provides information
-to the driver about the socket in a socket connect() call. Source and
-destination tunnel and session ids are provided, as well as the file
-descriptor of a UDP socket. See struct pppol2tp_addr in
-include/linux/if_pppol2tp.h. Note that zero tunnel / session ids are
-treated specially. When creating the per-tunnel PPPoL2TP management
-socket in Step 2 above, zero source and destination session ids are
-specified, which tells the driver to prepare the supplied UDP file
-descriptor for use as an L2TP tunnel socket.
+to the kernel about the tunnel and session in a socket connect()
+call. Source and destination tunnel and session ids are provided, as
+well as the file descriptor of a UDP or L2TPIP socket. See struct
+pppol2tp_addr in `include/linux/if_pppol2tp.h`_. For historical reasons,
+there are unfortunately slightly different address structures for
+L2TPv2/L2TPv3 IPv4/IPv6 tunnels and userspace must use the appropriate
+structure that matches the tunnel socket type.
Userspace may control behavior of the tunnel or session using
setsockopt and ioctl on the PPPoX socket. The following socket

-Only the DEBUG option is supported by the special tunnel management

-
In addition to the standard PPP ioctls, a PPPIOCGL2TPSTATS is provided
to retrieve tunnel and session statistics from the kernel using the
PPPoX socket of the appropriate tunnel or session.
-For L2TPv3, userspace must use the netlink API defined in
-include/linux/l2tp.h to manage tunnel and session contexts. The
-general procedure to create a new L2TP tunnel with one session is:-
-
-1. Open a GENL socket using L2TP_GENL_NAME for configuring the kernel
- using netlink.
-
-2. Create a UDP or L2TPIP socket for the tunnel.
-
-3. Create a new L2TP tunnel using a L2TP_CMD_TUNNEL_CREATE
- request. Set attributes according to desired tunnel parameters,
- referencing the UDP or L2TPIP socket created in the previous step.
-
-4. Create a new L2TP session in the tunnel using a
- L2TP_CMD_SESSION_CREATE request.
-
-The tunnel and all of its sessions are closed when the tunnel socket
-is closed. The netlink API may also be used to delete sessions and
-tunnels. Configuration and status info may be set or read using netlink.
-
-The L2TP driver also supports static (unmanaged) L2TPv3 tunnels. These
-are where there is no L2TP control message exchange with the peer to
-setup the tunnel; the tunnel is configured manually at each end of the
-tunnel. There is no need for an L2TP userspace application in this
-case -- the tunnel socket is created by the kernel and configured
-using parameters sent in the L2TP_CMD_TUNNEL_CREATE netlink
-request. The "ip" utility of iproute2 has commands for managing static
-L2TPv3 tunnels; do "ip l2tp help" for more information.
+Sample userspace code:
+
+ - Create session PPPoX data socket::
+
+ struct sockaddr_pppol2tp sax;
+ int fd;
+
+ /* Note, the tunnel socket must be bound already, else it
+ * will not be ready
+ */
+ sax.sa_family = AF_PPPOX;
+ sax.sa_protocol = PX_PROTO_OL2TP;
+ sax.pppol2tp.fd = tunnel_fd;
+ sax.pppol2tp.addr.sin_addr.s_addr = addr->sin_addr.s_addr;
+ sax.pppol2tp.addr.sin_port = addr->sin_port;
+ sax.pppol2tp.addr.sin_family = AF_INET;
+ sax.pppol2tp.s_tunnel = tunnel_id;
+ sax.pppol2tp.s_session = session_id;
+ sax.pppol2tp.d_tunnel = peer_tunnel_id;
+ sax.pppol2tp.d_session = peer_session_id;
+
+ /* session_fd is the fd of the session's PPPoL2TP socket.
+ * tunnel_fd is the fd of the tunnel UDP / L2TPIP socket.
+ */
+ fd = connect(session_fd, (struct sockaddr *)&sax, sizeof(sax));
+ if (fd < 0 ) {
+ return -errno;
+ }
+ return 0;
+
+Old L2TPv2-only API
+-------------------
+
+When L2TP was first added to the Linux kernel in 2.6.23, it
+implemented only L2TPv2 and did not include a netlink API. Instead,
+tunnel and session instances in the kernel were managed directly using
+only PPPoL2TP sockets. The PPPoL2TP socket is used as described in
+section "PPPoL2TP Session Socket API" but tunnel and session instances
+are automatically created on a connect() of the socket instead of
+being created by a separate netlink request:
+
+ - Tunnels are managed using a tunnel management socket which is a
+ dedicated PPPoL2TP socket, connected to (invalid) session
+ id 0. The L2TP tunnel instance is created when the PPPoL2TP
+ tunnel management socket is connected and is destroyed when the
+ socket is closed.
+
+ - Session instances are created in the kernel when a PPPoL2TP
+ socket is connected to a non-zero session id. Session parameters
+ are set using setsockopt. The L2TP session instance is destroyed
+ when the socket is closed.
+
+This API is still supported but its use is discouraged. Instead, new
+L2TPv2 applications should use netlink to first create the tunnel and
+session, then create a PPPoL2TP socket for the session.
+
+Unmanaged L2TPv3 tunnels
+------------------------
+
+The kernel L2TP subsystem also supports static (unmanaged) L2TPv3
+tunnels. Unmanaged tunnels have no userspace tunnel socket, and
+exchange no control messages with the peer to set up the tunnel; the
+tunnel is configured manually at each end of the tunnel. All
+configuration is done using netlink. There is no need for an L2TP
+userspace application in this case -- the tunnel socket is created by
+the kernel and configured using parameters sent in the
+``L2TP_CMD_TUNNEL_CREATE`` netlink request. The ``ip`` utility of
+``iproute2`` has commands for managing static L2TPv3 tunnels; do ``ip
+l2tp help`` for more information.
Debugging
-=========
-
-The driver supports a flexible debug scheme where kernel trace
-messages may be optionally enabled per tunnel and per session. Care is
-needed when debugging a live system since the messages are not
-rate-limited and a busy system could be swamped. Userspace uses
-setsockopt on the PPPoX socket to set a debug mask.
+---------
-The following debug mask bits are available:
+The L2TP subsystem offers a range of debugging interfaces through the
+debugfs filesystem.
-================ ==============================
-L2TP_MSG_DEBUG verbose debug (if compiled in)
-L2TP_MSG_CONTROL userspace - kernel interface
-L2TP_MSG_SEQ sequence numbers handling
-L2TP_MSG_DATA data packets
-================ ==============================
+To access these interfaces, the debugfs filesystem must first be mounted::
-If enabled, files under a l2tp debugfs directory can be used to dump
-kernel state about L2TP tunnels and sessions. To access it, the
-debugfs filesystem must first be mounted::
+ # mount -t debugfs debugfs /debug
- # mount -t debugfs debugfs /debug
+Files under the l2tp directory can then be accessed, providing a summary
+of the current population of tunnel and session contexts existing in the
+kernel::
-Files under the l2tp directory can then be accessed::
-
- # cat /debug/l2tp/tunnels
+ # cat /debug/l2tp/tunnels
The debugfs files should not be used by applications to obtain L2TP
state information because the file format is subject to change. It is
implemented to provide extra debug information to help diagnose
-problems.) Users should use the netlink API.
+problems. Applications should instead use the netlink API.
-/proc/net/pppol2tp is also provided for backwards compatibility with
-the original pppol2tp driver. It lists information about L2TPv2
-tunnels and sessions only. Its use is discouraged.
+In addition the L2TP subsystem implements tracepoints using the standard
+kernel event tracing API. The available L2TP events can be reviewed as
+follows::
-Unmanaged L2TPv3 Tunnels
-========================
-
-Some commercial L2TP products support unmanaged L2TPv3 ethernet
-tunnels, where there is no L2TP control protocol; tunnels are
-configured at each side manually. New commands are available in
-iproute2's ip utility to support this.
-
-To create an L2TPv3 ethernet pseudowire between local host 192.168.1.1
-and peer 192.168.1.2, using IP addresses 10.5.1.1 and 10.5.1.2 for the
-tunnel endpoints::
-
- # ip l2tp add tunnel tunnel_id 1 peer_tunnel_id 1 udp_sport 5000 \
- udp_dport 5000 encap udp local 192.168.1.1 remote 192.168.1.2
- # ip l2tp add session tunnel_id 1 session_id 1 peer_session_id 1
- # ip -s -d show dev l2tpeth0
- # ip addr add 10.5.1.2/32 peer 10.5.1.1/32 dev l2tpeth0
- # ip li set dev l2tpeth0 up
-
-Choose IP addresses to be the address of a local IP interface and that
-of the remote system. The IP addresses of the l2tpeth0 interface can be
-anything suitable.
-
-Repeat the above at the peer, with ports, tunnel/session ids and IP
-addresses reversed. The tunnel and session IDs can be any non-zero
-32-bit number, but the values must be reversed at the peer.

Internal Implementation
=======================
-The driver keeps a struct l2tp_tunnel context per L2TP tunnel and a
-struct l2tp_session context for each session. The l2tp_tunnel is
-always associated with a UDP or L2TP/IP socket and keeps a list of
-sessions in the tunnel. The l2tp_session context keeps kernel state
-about the session. It has private data which is used for data specific
-to the session type. With L2TPv2, the session always carried PPP
-traffic. With L2TPv3, the session can also carry ethernet frames
-(ethernet pseudowire) or other data types such as ATM, HDLC or Frame
-Relay.
-
-When a tunnel is first opened, the reference count on the socket is
-increased using sock_hold(). This ensures that the kernel socket
-cannot be removed while L2TP's data structures reference it.
-
-Some L2TP sessions also have a socket (PPP pseudowires) while others
-do not (ethernet pseudowires). We can't use the socket reference count
-as the reference count for session contexts. The L2TP implementation
-therefore has its own internal reference counts on the session
-contexts.
-
-To Do
-=====
-
-Add L2TP tunnel switching support. This would route tunneled traffic
-from one L2TP tunnel into another. Specified in
-http://tools.ietf.org/html/draft-ietf-l2tpext-tunnel-switching-08
-
-Add L2TPv3 VLAN pseudowire support.
-
-Add L2TPv3 IP pseudowire support.
-
-Add L2TPv3 ATM pseudowire support.
+This section is for kernel developers and maintainers.
+
+Sockets
+-------
+
+UDP sockets are implemented by the networking core. When an L2TP
+tunnel is created using a UDP socket, the socket is set up as an
+encapsulated UDP socket by setting encap_rcv and encap_destroy
+callbacks on the UDP socket. l2tp_udp_encap_recv is called when
+packets are received on the socket. l2tp_udp_encap_destroy is called
+when userspace closes the socket.
+
+L2TPIP sockets are implemented in `net/l2tp/l2tp_ip.c`_ and
+`net/l2tp/l2tp_ip6.c`_.
+
+Tunnels
+-------
+
+The kernel keeps a struct l2tp_tunnel context per L2TP tunnel. The
+l2tp_tunnel is always associated with a UDP or L2TP/IP socket and
+keeps a list of sessions in the tunnel. When a tunnel is first
+registered with L2TP core, the reference count on the socket is
+increased. This ensures that the socket cannot be removed while L2TP's
+data structures reference it.
+
+Tunnels are identified by a unique tunnel id. The id is 16-bit for
+L2TPv2 and 32-bit for L2TPv3. Internally, the id is stored as a 32-bit
+value.
+
+Tunnels are kept in a per-net list, indexed by tunnel id. The tunnel
+id namespace is shared by L2TPv2 and L2TPv3. The tunnel context can be
+derived from the socket's sk_user_data.
+
+Handling tunnel socket close is perhaps the most tricky part of the
+L2TP implementation. If userspace closes a tunnel socket, the L2TP
+tunnel and all of its sessions must be closed and destroyed. Since the
+tunnel context holds a ref on the tunnel socket, the socket's
+sk_destruct won't be called until the tunnel sock_put's its
+socket. For UDP sockets, when userspace closes the tunnel socket, the
+socket's encap_destroy handler is invoked, which L2TP uses to initiate
+its tunnel close actions. For L2TPIP sockets, the socket's close
+handler initiates the same tunnel close actions. All sessions are
+first closed. Each session drops its tunnel ref. When the tunnel ref
+reaches zero, the tunnel puts its socket ref. When the socket is
+eventually destroyed, it's sk_destruct finally frees the L2TP tunnel
+context.
+
+Sessions
+--------
+
+The kernel keeps a struct l2tp_session context for each session. Each
+session has private data which is used for data specific to the
+session type. With L2TPv2, the session always carries PPP
+traffic. With L2TPv3, the session can carry Ethernet frames (Ethernet
+pseudowire) or other data types such as PPP, ATM, HDLC or Frame
+Relay. Linux currently implements only Ethernet and PPP session types.
+
+Some L2TP session types also have a socket (PPP pseudowires) while
+others do not (Ethernet pseudowires). We can't therefore use the
+socket reference count as the reference count for session
+contexts. The L2TP implementation therefore has its own internal
+reference counts on the session contexts.
+
+Like tunnels, L2TP sessions are identified by a unique
+session id. Just as with tunnel ids, the session id is 16-bit for
+L2TPv2 and 32-bit for L2TPv3. Internally, the id is stored as a 32-bit
+value.
+
+Sessions hold a ref on their parent tunnel to ensure that the tunnel
+stays extant while one or more sessions references it.
+
+Sessions are kept in a per-tunnel list, indexed by session id. L2TPv3
+sessions are also kept in a per-net list indexed by session id,
+because L2TPv3 session ids are unique across all tunnels and L2TPv3
+data packets do not contain a tunnel id in the header. This list is
+therefore needed to find the session context associated with a
+received data packet when the tunnel context cannot be derived from
+the tunnel socket.
+
+Although the L2TPv3 RFC specifies that L2TPv3 session ids are not
+scoped by the tunnel, the kernel does not police this for L2TPv3 UDP
+tunnels and does not add sessions of L2TPv3 UDP tunnels into the
+per-net session list. In the UDP receive code, we must trust that the
+tunnel can be identified using the tunnel socket's sk_user_data and
+lookup the session in the tunnel's session list instead of the per-net
+session list.
+
+PPP
+---
+
+`net/l2tp/l2tp_ppp.c`_ implements the PPPoL2TP socket family. Each PPP
+session has a PPPoL2TP socket.
+
+The PPPoL2TP socket's sk_user_data references the l2tp_session.
+
+Userspace sends and receives PPP packets over L2TP using a PPPoL2TP
+socket. Only PPP control frames pass over this socket: PPP data
+packets are handled entirely by the kernel, passing between the L2TP
+session and its associated ``pppN`` netdev through the PPP channel
+interface of the kernel PPP subsystem.
+
+The L2TP PPP implementation handles the closing of a PPPoL2TP socket
+by closing its corresponding L2TP session. This is complicated because
+it must consider racing with netlink session create/destroy requests
+and pppol2tp_connect trying to reconnect with a session that is in the
+process of being closed. Unlike tunnels, PPP sessions do not hold a
+ref on their associated socket, so code must be careful to sock_hold
+the socket where necessary. For all the details, see commit
+3d609342cc04129ff7568e19316ce3d7451a27e8.
+
+Ethernet
+--------
+
+`net/l2tp/l2tp_eth.c`_ implements L2TPv3 Ethernet pseudowires. It
+manages a netdev for each session.
+
+L2TP Ethernet sessions are created and destroyed by netlink request,
+or are destroyed when the tunnel is destroyed. Unlike PPP sessions,
+Ethernet sessions do not have an associated socket.
Miscellaneous
=============
-The L2TP drivers were developed as part of the OpenL2TP project by
-Katalix Systems Ltd. OpenL2TP is a full-featured L2TP client / server,
-designed from the ground up to have the L2TP datapath in the
-kernel. The project also implemented the pppol2tp plugin for pppd
-which allows pppd to use the kernel driver. Details can be found at
-http://www.openl2tp.org.
+RFCs
+----
+
+The kernel code implements the datapath features specified in the
+following RFCs:
+
+======= =============== ===================================
+RFC2661 L2TPv2 https://tools.ietf.org/html/rfc2661
+RFC3931 L2TPv3 https://tools.ietf.org/html/rfc3931
+RFC4719 L2TPv3 Ethernet https://tools.ietf.org/html/rfc4719
+======= =============== ===================================
+
+Implementations
+---------------
+
+A number of open source applications use the L2TP kernel subsystem:
+
+============ ==============================================
+iproute2 https://github.com/shemminger/iproute2
+go-l2tp https://github.com/katalix/go-l2tp
+tunneldigger https://github.com/wlanslovenija/tunneldigger
+xl2tpd https://github.com/xelerance/xl2tpd
+============ ==============================================
+
+Limitations
+-----------
+
+The current implementation has a number of limitations:
+
+ 1) Multiple UDP sockets with the same 5-tuple address cannot be
+ used. The kernel's tunnel context is identified using private
+ data associated with the socket so it is important that each
+ socket is uniquely identified by its address.
+
+ 2) Interfacing with openvswitch is not yet implemented. It may be
+ useful to map OVS Ethernet and VLAN ports into L2TPv3 tunnels.
+
+ 3) VLAN pseudowires are implemented using an ``l2tpethN`` interface
+ configured with a VLAN sub-interface. Since L2TPv3 VLAN
+ pseudowires carry one and only one VLAN, it may be better to use
+ a single netdevice rather than an ``l2tpethN`` and ``l2tpethN``:M
+ pair per VLAN session. The netlink attribute
+ ``L2TP_ATTR_VLAN_ID`` was added for this, but it was never
+ implemented.
+
+Testing
+-------
+
+Unmanaged L2TPv3 Ethernet features are tested by the kernel's built-in
+selftests. See `tools/testing/selftests/net/l2tp.sh`_.
+
+Another test suite, l2tp-ktest_, covers all
+of the L2TP APIs and tunnel/session types. This may be integrated into
+the kernel's built-in L2TP selftests in the future.

+====================
+Interface statistics
+====================
+
+Overview
+========
+
+This document is a guide to Linux network interface statistics.
+
+There are three main sources of interface statistics in Linux:
+
+ - standard interface statistics based on
+ :c:type:`struct rtnl_link_stats64 <rtnl_link_stats64>`;
+ - protocol-specific statistics; and
+ - driver-defined statistics available via ethtool.
+
+Standard interface statistics
+-----------------------------
+
+There are multiple interfaces to reach the standard statistics.
+Most commonly used is the `ip` command from `iproute2`::
+
+ $ ip -s -s link show dev ens4u1u1
+ 6: ens4u1u1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
+ link/ether 48:2a:e3:4c:b1:d1 brd ff:ff:ff:ff:ff:ff
+ RX: bytes packets errors dropped overrun mcast
+ 74327665117 69016965 0 0 0 0
+ RX errors: length crc frame fifo missed
+ 0 0 0 0 0
+ TX: bytes packets errors dropped carrier collsns
+ 21405556176 44608960 0 0 0 0
+ TX errors: aborted fifo window heartbeat transns
+ 0 0 0 0 128
+ altname enp58s0u1u1
+
+Note that `-s` has been specified twice to see all members of
+:c:type:`struct rtnl_link_stats64 <rtnl_link_stats64>`.
+If `-s` is specified once the detailed errors won't be shown.
+
+`ip` supports JSON formatting via the `-j` option.
+
+Protocol-specific statistics
+----------------------------
+
+Some of the interfaces used for configuring devices are also able
+to report related statistics. For example ethtool interface used
+to configure pause frames can report corresponding hardware counters::
+
+ $ ethtool --include-statistics -a eth0
+ Pause parameters for eth0:
+ Autonegotiate: on
+ RX: on
+ TX: on
+ Statistics:
+ tx_pause_frames: 1
+ rx_pause_frames: 1
+
+Driver-defined statistics
+-------------------------
+
+Driver-defined ethtool statistics can be dumped using `ethtool -S $ifc`, e.g.::
+
+ $ ethtool -S ens4u1u1
+ NIC statistics:
+ tx_single_collisions: 0
+ tx_multi_collisions: 0
+
+uAPIs
+=====
+
+procfs
+------
+
+The historical `/proc/net/dev` text interface gives access to the list
+of interfaces as well as their statistics.
+
+Note that even though this interface is using
+:c:type:`struct rtnl_link_stats64 <rtnl_link_stats64>`
+internally it combines some of the fields.
+
+sysfs
+-----
+
+Each device directory in sysfs contains a `statistics` directory (e.g.
+`/sys/class/net/lo/statistics/`) with files corresponding to
+members of :c:type:`struct rtnl_link_stats64 <rtnl_link_stats64>`.
+
+This simple interface is convenient especially in constrained/embedded
+environments without access to tools. However, it's inefficient when
+reading multiple stats as it internally performs a full dump of
+:c:type:`struct rtnl_link_stats64 <rtnl_link_stats64>`
+and reports only the stat corresponding to the accessed file.
+
+Sysfs files are documented in
+`Documentation/ABI/testing/sysfs-class-net-statistics`.
+
+
+netlink
+-------
+
+`rtnetlink` (`NETLINK_ROUTE`) is the preferred method of accessing
+:c:type:`struct rtnl_link_stats64 <rtnl_link_stats64>` stats.
+
+Statistics are reported both in the responses to link information
+requests (`RTM_GETLINK`) and statistic requests (`RTM_GETSTATS`,
+when `IFLA_STATS_LINK_64` bit is set in the `.filter_mask` of the request).
+
+ethtool
+-------
+
+Ethtool IOCTL interface allows drivers to report implementation
+specific statistics. Historically it has also been used to report
+statistics for which other APIs did not exist, like per-device-queue
+statistics, or standard-based statistics (e.g. RFC 2863).
+
+Statistics and their string identifiers are retrieved separately.
+Identifiers via `ETHTOOL_GSTRINGS` with `string_set` set to `ETH_SS_STATS`,
+and values via `ETHTOOL_GSTATS`. User space should use `ETHTOOL_GDRVINFO`
+to retrieve the number of statistics (`.n_stats`).
+
+ethtool-netlink
+---------------
+
+Ethtool netlink is a replacement for the older IOCTL interface.
+
+Protocol-related statistics can be requested in get commands by setting
+the `ETHTOOL_FLAG_STATS` flag in `ETHTOOL_A_HEADER_FLAGS`. Currently
+statistics are supported in the following commands:
+
+ - `ETHTOOL_MSG_PAUSE_GET`
+
+debugfs
+-------
+
+Some drivers expose extra statistics via `debugfs`.
+
+struct rtnl_link_stats64
+========================
+
+.. kernel-doc:: include/uapi/linux/if_link.h
+ :identifiers: rtnl_link_stats64
+
+Notes for driver authors
+========================
+
+Drivers should report all statistics which have a matching member in
+:c:type:`struct rtnl_link_stats64 <rtnl_link_stats64>` exclusively
+via `.ndo_get_stats64`. Reporting such standard stats via ethtool
+or debugfs will not be accepted.
+
+Drivers must ensure best possible compliance with
+:c:type:`struct rtnl_link_stats64 <rtnl_link_stats64>`.
+Please note for example that detailed error statistics must be
+added into the general `rx_error` / `tx_error` counters.
+
+The `.ndo_get_stats64` callback can not sleep because of accesses
+via `/proc/net/dev`. If driver may sleep when retrieving the statistics
+from the device it should do so periodically asynchronously and only return
+a recent copy from `.ndo_get_stats64`. Ethtool interrupt coalescing interface
+allows setting the frequency of refreshing statistics, if needed.
+
+Retrieving ethtool statistics is a multi-syscall process, drivers are advised
+to keep the number of statistics constant to avoid race conditions with
+user space trying to read them.
+
+Statistics must persist across routine operations like bringing the interface
+down and up.
+
+Kernel-internal data structures
+-------------------------------
+
+The following structures are internal to the kernel, their members are
+translated to netlink attributes when dumped. Drivers must not overwrite
+the statistics they don't report with 0.

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

-If you must generate your patches by hand, use ``diff -up`` or ``diff -uprN``
-to create patches. Git generates patches in this form by default; if
-you're using ``git``, you can skip this section entirely.
-
-All changes to the Linux kernel occur in the form of patches, as

-create it in "unified diff" format, as supplied by the ``-u`` argument
-to :manpage:`diff(1)`.
-Also, please use the ``-p`` argument which shows which C function each
-change is in - that makes the resultant ``diff`` a lot easier to read.
-Patches should be based in the root kernel source directory,
-not in any lower subdirectory.
-
-To create a patch for a single file, it is often sufficient to do::

- tar xvfz linux-3.19.tar.gz

-``dontdiff`` is a list of files which are generated by the kernel during
-the build process, and should be ignored in any :manpage:`diff(1)`-generated

-
-Make sure your patch does not include any extra files which do not
-belong in a patch submission. Make sure to review your patch -after-
-generating it with :manpage:`diff(1)`, to ensure accuracy.
-
-If your changes produce a lot of deltas, you need to split them into
-individual patches which modify things in logical stages; see
-:ref:`split_changes`. This will facilitate review by other kernel developers,

-
-If you have a series of patches, it may be most convenient to have the

-As a result, many subsystem maintainers are reluctant to take pull
-requests, especially from new, unknown developers. If in doubt you can use
-the pull request as the cover letter for a normal posting of the patch
-series, giving the maintainer the option of using either.
-
-A pull request should have [GIT PULL] in the subject line. The
-request itself should include the repository name and the branch of
-interest on a single line; it should look something like::
-
- Please pull from
-
- git://jdelvare.pck.nerim.net/jdelvare-2.6 i2c-for-linus
-
- to get these changes:
-
-A pull request should also include an overall message saying what will be
-included in the request, a ``git shortlog`` listing of the patches
-themselves, and a ``diffstat`` showing the overall effect of the patch series.
-The easiest way to get all this information together is, of course, to let
-``git`` do it for you with the ``git request-pull`` command.
-
-Some maintainers (including Linus) want to see pull requests from signed
-commits; that increases their confidence that the request actually came
-from you. Linus, in particular, will not pull from public hosting sites
-like GitHub in the absence of a signed tag.
-
-The first step toward creating such tags is to make a GNUPG key and get it
-signed by one or more core kernel developers. This step can be hard for
-new developers, but there is no way around it. Attending conferences can
-be a good way to find developers who can sign your key.
-
-Once you have prepared a patch series in ``git`` that you wish to have somebody
-pull, create a signed tag with ``git tag -s``. This will create a new tag
-identifying the last commit in the series and containing a signature
-created with your private key. You will also have the opportunity to add a
-changelog-style message to the tag; this is an ideal place to describe the
-effects of the pull request as a whole.
-
-If the tree the maintainer will be pulling from is not the repository you
-are working from, don't forget to push the signed tag explicitly to the
-public tree.
-
-When generating your pull request, use the signed tag as the target. A
-command like this will do the trick::
-
- git request-pull master git://my.public.tree/linux.git my-signed-tag

-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.

+==================================
+AArch64 Linux 中扩展的活动监控单元
+==================================
+
+作者: Ionela Voinescu <ionela.voinescu@arm.com>
+
+日期: 2019-09-10
+
+本文档简要描述了 AArch64 Linux 支持的活动监控单元的规范。
+
+
+架构总述
+--------
+
+活动监控是 ARMv8.4 CPU 架构引入的一个可选扩展特性。
+
+活动监控单元(在每个 CPU 中实现)为系统管理提供了性能计数器。既可以通
+过系统寄存器的方式访问计数器,同时也支持外部内存映射的方式访问计数器。
+
+AMUv1 架构实现了一个由4个固定的64位事件计数器组成的计数器组。
+
+ - CPU 周期计数器:同 CPU 的频率增长
+ - 常量计数器:同固定的系统时钟频率增长
+ - 淘汰指令计数器: 同每次架构指令执行增长
+ - 内存停顿周期计数器:计算由在时钟域内的最后一级缓存中未命中而引起
+ 的指令调度停顿周期数
+
+当处于 WFI 或者 WFE 状态时,计数器不会增长。
+
+AMU 架构提供了一个高达16位的事件计数器空间,未来新的 AMU 版本中可能
+用它来实现新增的事件计数器。
+
+另外,AMUv1 实现了一个多达16个64位辅助事件计数器的计数器组。
+
+冷复位时所有的计数器会清零。
+
+
+基本支持
+--------
+
+内核可以安全地运行在支持 AMU 和不支持 AMU 的 CPU 组合中。
+因此,当配置 CONFIG_ARM64_AMU_EXTN 后我们无条件使能后续
+(secondary or hotplugged) CPU 检测和使用这个特性。
+
+当在 CPU 上检测到该特性时,我们会标记为特性可用但是不能保证计数器的功能,
+仅表明有扩展属性。
+
+固件(代码运行在高异常级别,例如 arm-tf )需支持以下功能:
+
+ - 提供低异常级别(EL2 和 EL1)访问 AMU 寄存器的能力。
+ - 使能计数器。如果未使能,它的值应为 0。
+ - 在从电源关闭状态启动 CPU 前或后保存或者恢复计数器。
+
+当使用使能了该特性的内核启动但固件损坏时,访问计数器寄存器可能会遭遇
+panic 或者死锁。即使未发现这些症状,计数器寄存器返回的数据结果并不一
+定能反映真实情况。通常,计数器会返回 0,表明他们未被使能。
+
+如果固件没有提供适当的支持最好关闭 CONFIG_ARM64_AMU_EXTN。
+值得注意的是,出于安全原因,不要绕过 AMUSERRENR_EL0 设置而捕获从
+EL0(用户空间) 访问 EL1(内核空间)。 因此,固件应该确保访问 AMU寄存器
+不会困在 EL2或EL3。
+
+AMUv1 的固定计数器可以通过如下系统寄存器访问:
+
+ - SYS_AMEVCNTR0_CORE_EL0
+ - SYS_AMEVCNTR0_CONST_EL0
+ - SYS_AMEVCNTR0_INST_RET_EL0
+ - SYS_AMEVCNTR0_MEM_STALL_EL0
+
+特定辅助计数器可以通过 SYS_AMEVCNTR1_EL0(n) 访问,其中n介于0到15。
+
+详细信息定义在目录:arch/arm64/include/asm/sysreg.h。
+
+
+用户空间访问
+------------
+
+由于以下原因,当前禁止从用户空间访问 AMU 的寄存器:
+
+ - 安全因数:可能会暴露处于安全模式执行的代码信息。
+ - 意愿:AMU 是用于系统管理的。
+
+同样,该功能对用户空间不可见。
+
+
+虚拟化
+------
+
+由于以下原因,当前禁止从 KVM 客户端的用户空间(EL0)和内核空间(EL1)
+访问 AMU 的寄存器:
+
+ - 安全因数:可能会暴露给其他客户端或主机端执行的代码信息。
+
+任何试图访问 AMU 寄存器的行为都会触发一个注册在客户端的未定义异常。

+ARM64中的 HugeTLBpage
+=====================
+
+大页依靠有效利用 TLBs 来提高地址翻译的性能。这取决于以下
+两点 -
+
+ - 大页的大小
+ - TLBs 支持的条目大小
+
+ARM64 接口支持2种大页方式。
+
+1) pud/pmd 级别的块映射
+-----------------------
+
+这是常规大页,他们的 pmd 或 pud 页面表条目指向一个内存块。
+不管 TLB 中支持的条目大小如何,块映射可以减少翻译大页地址
+所需遍历的页表深度。
+
+2) 使用连续位
+-------------
+
+架构中转换页表条目(D4.5.3, ARM DDI 0487C.a)中提供一个连续
+位告诉 MMU 这个条目是一个连续条目集的一员,它可以被缓存在单
+个 TLB 条目中。
+
+在 Linux 中连续位用来增加 pmd 和 pte(最后一级)级别映射的大
+小。受支持的连续页表条目数量因页面大小和页表级别而异。
+
+
+支持以下大页尺寸配置 -

+=====================================
+IOMMU Userspace API
+=====================================
+
+IOMMU UAPI is used for virtualization cases where communications are
+needed between physical and virtual IOMMU drivers. For baremetal
+usage, the IOMMU is a system device which does not need to communicate
+with userspace directly.
+
+The primary use cases are guest Shared Virtual Address (SVA) and
+guest IO virtual address (IOVA), wherein the vIOMMU implementation
+relies on the physical IOMMU and for this reason requires interactions
+with the host driver.
+
+.. contents:: :local:
+
+Functionalities
+===============
+Communications of user and kernel involve both directions. The
+supported user-kernel APIs are as follows:
+
+1. Bind/Unbind guest PASID (e.g. Intel VT-d)
+2. Bind/Unbind guest PASID table (e.g. ARM SMMU)
+3. Invalidate IOMMU caches upon guest requests
+4. Report errors to the guest and serve page requests
+
+Requirements
+============
+The IOMMU UAPIs are generic and extensible to meet the following
+requirements:
+
+1. Emulated and para-virtualised vIOMMUs
+2. Multiple vendors (Intel VT-d, ARM SMMU, etc.)
+3. Extensions to the UAPI shall not break existing userspace
+
+Interfaces
+==========
+Although the data structures defined in IOMMU UAPI are self-contained,
+there are no user API functions introduced. Instead, IOMMU UAPI is
+designed to work with existing user driver frameworks such as VFIO.
+
+Extension Rules & Precautions
+-----------------------------
+When IOMMU UAPI gets extended, the data structures can *only* be
+modified in two ways:
+
+1. Adding new fields by re-purposing the padding[] field. No size change.
+2. Adding new union members at the end. May increase the structure sizes.
+
+No new fields can be added *after* the variable sized union in that it
+will break backward compatibility when offset moves. A new flag must
+be introduced whenever a change affects the structure using either
+method. The IOMMU driver processes the data based on flags which
+ensures backward compatibility.
+
+Version field is only reserved for the unlikely event of UAPI upgrade
+at its entirety.
+
+It's *always* the caller's responsibility to indicate the size of the
+structure passed by setting argsz appropriately.
+Though at the same time, argsz is user provided data which is not
+trusted. The argsz field allows the user app to indicate how much data
+it is providing; it's still the kernel's responsibility to validate
+whether it's correct and sufficient for the requested operation.
+
+Compatibility Checking
+----------------------
+When IOMMU UAPI extension results in some structure size increase,
+IOMMU UAPI code shall handle the following cases:
+
+1. User and kernel has exact size match
+2. An older user with older kernel header (smaller UAPI size) running on a
+ newer kernel (larger UAPI size)
+3. A newer user with newer kernel header (larger UAPI size) running
+ on an older kernel.
+4. A malicious/misbehaving user passing illegal/invalid size but within
+ range. The data may contain garbage.
+
+Feature Checking
+----------------
+While launching a guest with vIOMMU, it is strongly advised to check
+the compatibility upfront, as some subsequent errors happening during
+vIOMMU operation, such as cache invalidation failures cannot be nicely
+escalated to the guest due to IOMMU specifications. This can lead to
+catastrophic failures for the users.
+
+User applications such as QEMU are expected to import kernel UAPI
+headers. Backward compatibility is supported per feature flags.
+For example, an older QEMU (with older kernel header) can run on newer
+kernel. Newer QEMU (with new kernel header) may refuse to initialize
+on an older kernel if new feature flags are not supported by older
+kernel. Simply recompiling existing code with newer kernel header should
+not be an issue in that only existing flags are used.
+
+IOMMU vendor driver should report the below features to IOMMU UAPI
+consumers (e.g. via VFIO).
+
+1. IOMMU_NESTING_FEAT_SYSWIDE_PASID
+2. IOMMU_NESTING_FEAT_BIND_PGTBL
+3. IOMMU_NESTING_FEAT_BIND_PASID_TABLE
+4. IOMMU_NESTING_FEAT_CACHE_INVLD
+5. IOMMU_NESTING_FEAT_PAGE_REQUEST
+
+Take VFIO as example, upon request from VFIO userspace (e.g. QEMU),
+VFIO kernel code shall query IOMMU vendor driver for the support of
+the above features. Query result can then be reported back to the
+userspace caller. Details can be found in
+Documentation/driver-api/vfio.rst.
+
+
+Data Passing Example with VFIO
+------------------------------
+As the ubiquitous userspace driver framework, VFIO is already IOMMU
+aware and shares many key concepts such as device model, group, and
+protection domain. Other user driver frameworks can also be extended
+to support IOMMU UAPI but it is outside the scope of this document.
+
+In this tight-knit VFIO-IOMMU interface, the ultimate consumer of the
+IOMMU UAPI data is the host IOMMU driver. VFIO facilitates user-kernel
+transport, capability checking, security, and life cycle management of
+process address space ID (PASID).
+
+VFIO layer conveys the data structures down to the IOMMU driver. It
+follows the pattern below::
+
+ struct {
+ __u32 argsz;
+ __u32 flags;
+ __u8 data[];
+ };
+
+Here data[] contains the IOMMU UAPI data structures. VFIO has the
+freedom to bundle the data as well as parse data size based on its own flags.
+
+In order to determine the size and feature set of the user data, argsz
+and flags (or the equivalent) are also embedded in the IOMMU UAPI data
+structures.
+
+A "__u32 argsz" field is *always* at the beginning of each structure.
+
+For example:
+::
+
+ struct iommu_cache_invalidate_info {
+ __u32 argsz;
+ #define IOMMU_CACHE_INVALIDATE_INFO_VERSION_1 1
+ __u32 version;
+ /* IOMMU paging structure cache */
+ #define IOMMU_CACHE_INV_TYPE_IOTLB (1 << 0) /* IOMMU IOTLB */
+ #define IOMMU_CACHE_INV_TYPE_DEV_IOTLB (1 << 1) /* Device IOTLB */
+ #define IOMMU_CACHE_INV_TYPE_PASID (1 << 2) /* PASID cache */
+ #define IOMMU_CACHE_INV_TYPE_NR (3)
+ __u8 cache;
+ __u8 granularity;
+ __u8 padding[6];
+ union {
+ struct iommu_inv_pasid_info pasid_info;
+ struct iommu_inv_addr_info addr_info;
+ } granu;
+ };
+
+VFIO is responsible for checking its own argsz and flags. It then
+invokes appropriate IOMMU UAPI functions. The user pointers are passed
+to the IOMMU layer for further processing. The responsibilities are
+divided as follows:
+
+- Generic IOMMU layer checks argsz range based on UAPI data in the
+ current kernel version.
+
+- Generic IOMMU layer checks content of the UAPI data for non-zero
+ reserved bits in flags, padding fields, and unsupported version.
+ This is to ensure not breaking userspace in the future when these
+ fields or flags are used.
+
+- Vendor IOMMU driver checks argsz based on vendor flags. UAPI data
+ is consumed based on flags. Vendor driver has access to
+ unadulterated argsz value in case of vendor specific future
+ extensions. Currently, it does not perform the copy_from_user()
+ itself. A __user pointer can be provided in some future scenarios
+ where there's vendor data outside of the structure definition.
+
+IOMMU code treats UAPI data in two categories:
+
+- structure contains vendor data
+ (Example: iommu_uapi_cache_invalidate())
+
+- structure contains only generic data
+ (Example: iommu_uapi_sva_bind_gpasid())
+
+
+
+Sharing UAPI with in-kernel users
+---------------------------------
+For UAPIs that are shared with in-kernel users, a wrapper function is
+provided to distinguish the callers. For example,
+
+Userspace caller ::
+
+ int iommu_uapi_sva_unbind_gpasid(struct iommu_domain *domain,
+ struct device *dev,
+ void __user *udata)
+
+In-kernel caller ::
+
+ int iommu_sva_unbind_gpasid(struct iommu_domain *domain,
+ struct device *dev, ioasid_t ioasid);

-Device Naming
-=============
+Controlling a hardware peripheral via V4L2
+==========================================
+
+Hardware that is supported using the V4L2 uAPI often consists of multiple
+devices or peripherals, each of which have their own driver.
+
+The bridge driver exposes one or more V4L2 device nodes
+(see :ref:`v4l2_device_naming`).
+
+There are other drivers providing support for other components of
+the hardware, which may also expose device nodes, called V4L2 sub-devices.
+
+When such V4L2 sub-devices are exposed, they allow controlling those
+other hardware components - usually connected via a serial bus (like
+I²C, SMBus or SPI). Depending on the bridge driver, those sub-devices
+can be controlled indirectly via the bridge driver or explicitly via
+the :ref:`Media Controller <media_controller>` and via the
+:ref:`V4L2 sub-devices <subdev>`.
+
+The devices that require the use of the
+:ref:`Media Controller <media_controller>` are called **MC-centric**
+devices. The devices that are fully controlled via V4L2 device nodes
+are called **video-node-centric**.
+
+Userspace can check if a V4L2 hardware peripheral is MC-centric by
+calling :ref:`VIDIOC_QUERYCAP` and checking the
+:ref:`device_caps field <device-capabilities>`.
+
+If the device returns ``V4L2_CAP_IO_MC`` flag at ``device_caps``,
+then it is MC-centric, otherwise, it is video-node-centric.
+
+It is required for MC-centric drivers to identify the V4L2
+sub-devices and to configure the pipelines via the
+:ref:`media controller API <media_controller>` before using the peripheral.
+Also, the sub-devices' configuration shall be controlled via the
+:ref:`sub-device API <subdev>`.
+
+.. note::
+
+ A video-node-centric may still provide media-controller and
+ sub-device interfaces as well.
+
+ However, in that case the media-controller and the sub-device
+ interfaces are read-only and just provide information about the
+ device. The actual configuration is done via the video nodes.
+

+========================
+
+The configuration parameters are passed to the

+a single instance of the C structure :c:type:`rkisp1_params_cfg` defined in

+3A and histogram statistics
+===========================
+
+The ISP1 device collects different statistics over an input Bayer frame.
+Those statistics are obtained from the :ref:`rkisp1_stats <rkisp1_stats>`
+metadata capture video node,
+using the :c:type:`v4l2_meta_format` interface. The buffer contains a single
+instance of the C structure :c:type:`rkisp1_stat_buffer` defined in

+
+.. code-block:: c
+
+ struct rkisp1_stat_buffer *stats = (struct rkisp1_stat_buffer*) buffer;
+
+The statistics collected are Exposure, AWB (Auto-white balance), Histogram and
+AF (Auto-focus). See :c:type:`rkisp1_stat_buffer` for details of the statistics.
+
+The 3A statistics and configuration parameters described here are usually

+
+This ioctl allows user space to define up to 16 bitmaps of MSR ranges to
+specify whether a certain MSR access should be explicitly filtered for or not.
+
+If this ioctl has never been invoked, MSR accesses are not guarded and the

+
+Calling this ioctl with an empty set of ranges (all nmsrs == 0) disables MSR

+
+As soon as the filtering is in place, every MSR access is processed through
+the filtering except for accesses to the x2APIC MSRs (from 0x800 to 0x8ff);
+x2APIC MSRs are always allowed, independent of the ``default_allow`` setting,
+and their behavior depends on the ``X2APIC_ENABLE`` bit of the APIC base
+register.
+
+If a bit is within one of the defined ranges, read and write accesses are
+guarded by the bitmap's value for the MSR index if the kind of access
+is included in the ``struct kvm_msr_filter_range`` flags. If no range
+cover this particular access, the behavior is determined by the flags
+field in the kvm_msr_filter struct: ``KVM_MSR_FILTER_DEFAULT_ALLOW``
+and ``KVM_MSR_FILTER_DEFAULT_DENY``.
+
+Each bitmap range specifies a range of MSRs to potentially allow access on.
+The range goes from MSR index [base .. base+nmsrs]. The flags field
+indicates whether reads, writes or both reads and writes are filtered
+by setting a 1 bit in the bitmap for the corresponding MSR index.
+
+If an MSR access is not permitted through the filtering, it generates a
+#GP inside the guest. When combined with KVM_CAP_X86_USER_SPACE_MSR, that
+allows user space to deflect and potentially handle various MSR accesses
+into user space.
+
+If a vCPU is in running state while this ioctl is invoked, the vCPU may

+8.24 KVM_CAP_STEAL_TIME

+:Architectures: arm64, x86
+
+This capability indicates that KVM supports steal time accounting.
+When steal time accounting is supported it may be enabled with

+specific interfaces must be consistent, i.e. if one says the feature
+is supported, than the other should as well and vice versa. For arm64

+
+8.25 KVM_CAP_S390_DIAG318
+-------------------------
+
+:Architectures: s390
+
+This capability enables a guest to set information about its control program
+(i.e. guest kernel type and version). The information is helpful during
+system/firmware service events, providing additional data about the guest
+environments running on the machine.
+
+The information is associated with the DIAGNOSE 0x318 instruction, which sets
+an 8-byte value consisting of a one-byte Control Program Name Code (CPNC) and
+a 7-byte Control Program Version Code (CPVC). The CPNC determines what
+environment the control program is running in (e.g. Linux, z/VM...), and the
+CPVC is used for information specific to OS (e.g. Linux version, Linux
+distribution...)
+
+If this capability is available, then the CPNC and CPVC can be synchronized
+between KVM and userspace via the sync regs mechanism (KVM_SYNC_DIAG318).
+
+8.26 KVM_CAP_X86_USER_SPACE_MSR
+-------------------------------
+
+:Architectures: x86
+
+This capability indicates that KVM supports deflection of MSR reads and
+writes to user space. It can be enabled on a VM level. If enabled, MSR
+accesses that would usually trigger a #GP by KVM into the guest will
+instead get bounced to user space through the KVM_EXIT_X86_RDMSR and
+KVM_EXIT_X86_WRMSR exit notifications.
+
+8.25 KVM_X86_SET_MSR_FILTER
+---------------------------
+
+:Architectures: x86
+
+This capability indicates that KVM supports that accesses to user defined MSRs
+may be rejected. With this capability exposed, KVM exports new VM ioctl
+KVM_X86_SET_MSR_FILTER which user space can call to specify bitmaps of MSR
+ranges that KVM should reject access to.
+
+In combination with KVM_CAP_X86_USER_SPACE_MSR, this allows user space to
+trap and emulate MSRs that are outside of the scope of KVM as well as
+limit the attack surface on KVM's MSR emulation code.

+
+When enabled, KVM will disable paravirtual features provided to the

+
+Restrictions: Event 0 (SW_INCR) is never filtered, as it doesn't count a

+isn't strictly speaking an event. Filtering the cycle counter is possible
+using event 0x11 (CPU_CYCLES).

+Nitro Enclaves
+==============
+
+Overview
+========
+
+Nitro Enclaves (NE) is a new Amazon Elastic Compute Cloud (EC2) capability
+that allows customers to carve out isolated compute environments within EC2
+instances [1].
+
+For example, an application that processes sensitive data and runs in a VM,
+can be separated from other applications running in the same VM. This
+application then runs in a separate VM than the primary VM, namely an enclave.
+
+An enclave runs alongside the VM that spawned it. This setup matches low latency
+applications needs. The resources that are allocated for the enclave, such as
+memory and CPUs, are carved out of the primary VM. Each enclave is mapped to a
+process running in the primary VM, that communicates with the NE driver via an
+ioctl interface.
+
+In this sense, there are two components:
+
+1. An enclave abstraction process - a user space process running in the primary
+VM guest that uses the provided ioctl interface of the NE driver to spawn an
+enclave VM (that's 2 below).
+
+There is a NE emulated PCI device exposed to the primary VM. The driver for this
+new PCI device is included in the NE driver.
+
+The ioctl logic is mapped to PCI device commands e.g. the NE_START_ENCLAVE ioctl
+maps to an enclave start PCI command. The PCI device commands are then
+translated into actions taken on the hypervisor side; that's the Nitro
+hypervisor running on the host where the primary VM is running. The Nitro
+hypervisor is based on core KVM technology.
+
+2. The enclave itself - a VM running on the same host as the primary VM that
+spawned it. Memory and CPUs are carved out of the primary VM and are dedicated
+for the enclave VM. An enclave does not have persistent storage attached.
+
+The memory regions carved out of the primary VM and given to an enclave need to
+be aligned 2 MiB / 1 GiB physically contiguous memory regions (or multiple of
+this size e.g. 8 MiB). The memory can be allocated e.g. by using hugetlbfs from
+user space [2][3]. The memory size for an enclave needs to be at least 64 MiB.
+The enclave memory and CPUs need to be from the same NUMA node.
+
+An enclave runs on dedicated cores. CPU 0 and its CPU siblings need to remain
+available for the primary VM. A CPU pool has to be set for NE purposes by an
+user with admin capability. See the cpu list section from the kernel
+documentation [4] for how a CPU pool format looks.
+
+An enclave communicates with the primary VM via a local communication channel,
+using virtio-vsock [5]. The primary VM has virtio-pci vsock emulated device,
+while the enclave VM has a virtio-mmio vsock emulated device. The vsock device
+uses eventfd for signaling. The enclave VM sees the usual interfaces - local
+APIC and IOAPIC - to get interrupts from virtio-vsock device. The virtio-mmio
+device is placed in memory below the typical 4 GiB.
+
+The application that runs in the enclave needs to be packaged in an enclave
+image together with the OS ( e.g. kernel, ramdisk, init ) that will run in the
+enclave VM. The enclave VM has its own kernel and follows the standard Linux
+boot protocol [6].
+
+The kernel bzImage, the kernel command line, the ramdisk(s) are part of the
+Enclave Image Format (EIF); plus an EIF header including metadata such as magic
+number, eif version, image size and CRC.
+
+Hash values are computed for the entire enclave image (EIF), the kernel and
+ramdisk(s). That's used, for example, to check that the enclave image that is
+loaded in the enclave VM is the one that was intended to be run.
+
+These crypto measurements are included in a signed attestation document
+generated by the Nitro Hypervisor and further used to prove the identity of the
+enclave; KMS is an example of service that NE is integrated with and that checks
+the attestation doc.
+
+The enclave image (EIF) is loaded in the enclave memory at offset 8 MiB. The
+init process in the enclave connects to the vsock CID of the primary VM and a
+predefined port - 9000 - to send a heartbeat value - 0xb7. This mechanism is
+used to check in the primary VM that the enclave has booted. The CID of the
+primary VM is 3.
+
+If the enclave VM crashes or gracefully exits, an interrupt event is received by
+the NE driver. This event is sent further to the user space enclave process
+running in the primary VM via a poll notification mechanism. Then the user space
+enclave process can exit.

-1. Introduction
-================
-
- Welcome to User Mode Linux. It's going to be fun.
-
-
-
-1.1. How is User Mode Linux Different?
----------------------------------------
-
- Normally, the Linux Kernel talks straight to your hardware (video
- card, keyboard, hard drives, etc), and any programs which run ask the
- kernel to operate the hardware, like so::
-
-
-
- +-----------+-----------+----+
- | Process 1 | Process 2 | ...|
- +-----------+-----------+----+
- | Linux Kernel |
- +----------------------------+
- | Hardware |
- +----------------------------+
-
-
-
-
- The User Mode Linux Kernel is different; instead of talking to the
- hardware, it talks to a `real` Linux kernel (called the `host kernel`
- from now on), like any other program. Programs can then run inside
- User-Mode Linux as if they were running under a normal kernel, like
- so::
-
-
-
- +----------------+
- | Process 2 | ...|
- +-----------+----------------+
- | Process 1 | User-Mode Linux|
- +----------------------------+
- | Linux Kernel |
- +----------------------------+
- | Hardware |
- +----------------------------+
-
-
-
-
-
-1.2. Why Would I Want User Mode Linux?
----------------------------------------
-
-
- 1. If User Mode Linux crashes, your host kernel is still fine.
-
- 2. You can run a usermode kernel as a non-root user.
-
- 3. You can debug the User Mode Linux like any normal process.
-
- 4. You can run gprof (profiling) and gcov (coverage testing).
-
- 5. You can play with your kernel without breaking things.
-
- 6. You can use it as a sandbox for testing new apps.
-
- 7. You can try new development kernels safely.
-
- 8. You can run different distributions simultaneously.
-
- 9. It's extremely fun.
-
-
-
-.. _Compiling_the_kernel_and_modules:
-
-2. Compiling the kernel and modules
-====================================
-
-
-
-
-2.1. Compiling the kernel
---------------------------
-
-
- Compiling the user mode kernel is just like compiling any other
- kernel.
-
-
- 1. Download the latest kernel from your favourite kernel mirror,
- such as:
-
- https://mirrors.edge.kernel.org/pub/linux/kernel/v5.x/linux-5.4.14.tar.xz
-
- 2. Make a directory and unpack the kernel into it::
-
- host%
- mkdir ~/uml
-
- host%
- cd ~/uml
-
- host%
- tar xvf linux-5.4.14.tar.xz
-
-
- 3. Run your favorite config; ``make xconfig ARCH=um`` is the most
- convenient. ``make config ARCH=um`` and ``make menuconfig ARCH=um``
- will work as well. The defaults will give you a useful kernel. If
- you want to change something, go ahead, it probably won't hurt
- anything.
-
-
- Note: If the host is configured with a 2G/2G address space split
- rather than the usual 3G/1G split, then the packaged UML binaries
- will not run. They will immediately segfault. See
- :ref:`UML_on_2G/2G_hosts` for the scoop on running UML on your system.
-
-
-
- 4. Finish with ``make linux ARCH=um``: the result is a file called
- ``linux`` in the top directory of your source tree.
-
-
-2.2. Compiling and installing kernel modules
----------------------------------------------
-
- UML modules are built in the same way as the native kernel (with the
- exception of the 'ARCH=um' that you always need for UML)::
-
-
- host% make modules ARCH=um
-
-
-
-
- Any modules that you want to load into this kernel need to be built in
- the user-mode pool. Modules from the native kernel won't work.
-
- You can install them by using ftp or something to copy them into the
- virtual machine and dropping them into ``/lib/modules/$(uname -r)``.
-
- You can also get the kernel build process to install them as follows:
-
- 1. with the kernel not booted, mount the root filesystem in the top
- level of the kernel pool::
-
-
- host% mount root_fs mnt -o loop
-
-
-
-
-
-
- 2. run::
-
-
- host%
- make modules_install INSTALL_MOD_PATH=`pwd`/mnt ARCH=um
-
-
-
-
-
-
- 3. unmount the filesystem::
-
-
- host% umount mnt
-
-
-
-
-
-
- 4. boot the kernel on it
-
-
- When the system is booted, you can use insmod as usual to get the
- modules into the kernel. A number of things have been loaded into UML
- as modules, especially filesystems and network protocols and filters,
- so most symbols which need to be exported probably already are.
- However, if you do find symbols that need exporting, let us
- know at http://user-mode-linux.sourceforge.net/, and
- they'll be "taken care of".
-
-
-
-2.3. Compiling and installing uml_utilities
---------------------------------------------
-
- Many features of the UML kernel require a user-space helper program,
- so a uml_utilities package is distributed separately from the kernel
- patch which provides these helpers. Included within this is:
-
- - port-helper - Used by consoles which connect to xterms or ports
-
- - tunctl - Configuration tool to create and delete tap devices
-
- - uml_net - Setuid binary for automatic tap device configuration
-
- - uml_switch - User-space virtual switch required for daemon
- transport
-
- The uml_utilities tree is compiled with::
-
-
- host#
- make && make install
-
-
-
-
- Note that UML kernel patches may require a specific version of the
- uml_utilities distribution. If you don't keep up with the mailing
- lists, ensure that you have the latest release of uml_utilities if you
- are experiencing problems with your UML kernel, particularly when
- dealing with consoles or command-line switches to the helper programs
-
-
-
-
-
-
-
-
-3. Running UML and logging in
-==============================
-
-
-
-3.1. Running UML
------------------
-
- It runs on 2.2.15 or later, and all kernel versions since 2.4.
-
-
- Booting UML is straightforward. Simply run 'linux': it will try to
- mount the file ``root_fs`` in the current directory. You do not need to
- run it as root. If your root filesystem is not named ``root_fs``, then
- you need to put a ``ubd0=root_fs_whatever`` switch on the linux command
- line.
-
-
- You will need a filesystem to boot UML from. There are a number
- available for download from http://user-mode-linux.sourceforge.net.
- There are also several tools at
- http://user-mode-linux.sourceforge.net/ which can be
- used to generate UML-compatible filesystem images from media.
- The kernel will boot up and present you with a login prompt.
-
-
-Note:
- If the host is configured with a 2G/2G address space split
- rather than the usual 3G/1G split, then the packaged UML binaries will
- not run. They will immediately segfault. See :ref:`UML_on_2G/2G_hosts`
- for the scoop on running UML on your system.
-
-
-
-3.2. Logging in
-----------------
-
-
-
- The prepackaged filesystems have a root account with password 'root'
- and a user account with password 'user'. The login banner will
- generally tell you how to log in. So, you log in and you will find
- yourself inside a little virtual machine. Our filesystems have a
- variety of commands and utilities installed (and it is fairly easy to
- add more), so you will have a lot of tools with which to poke around
- the system.
-
- There are a couple of other ways to log in:
-
- - On a virtual console
-
-
-
- Each virtual console that is configured (i.e. the device exists in
- /dev and /etc/inittab runs a getty on it) will come up in its own
- xterm. If you get tired of the xterms, read
- :ref:`setting_up_serial_lines_and_consoles` to see how to attach
- the consoles to something else, like host ptys.
-
-
-
- - Over the serial line
-
-
- In the boot output, find a line that looks like::
-
-
-
- serial line 0 assigned pty /dev/ptyp1
-
-
-
-
- Attach your favorite terminal program to the corresponding tty. I.e.
- for minicom, the command would be::
-
-
- host% minicom -o -p /dev/ttyp1
-
-
-
-
-
-
- - Over the net
-
-
- If the network is running, then you can telnet to the virtual
- machine and log in to it. See :ref:`Setting_up_the_network` to learn
- about setting up a virtual network.
-
- When you're done using it, run halt, and the kernel will bring itself
- down and the process will exit.
-
-
-3.3. Examples
---------------
-
- Here are some examples of UML in action:
-
- - A login session http://user-mode-linux.sourceforge.net/old/login.html
-
- - A virtual network http://user-mode-linux.sourceforge.net/old/net.html
-
-
-
-
-
-.. _UML_on_2G/2G_hosts:
-
-4. UML on 2G/2G hosts
-======================
-
-
-
-
-4.1. Introduction
-------------------
-
-
- Most Linux machines are configured so that the kernel occupies the
- upper 1G (0xc0000000 - 0xffffffff) of the 4G address space and
- processes use the lower 3G (0x00000000 - 0xbfffffff). However, some
- machine are configured with a 2G/2G split, with the kernel occupying
- the upper 2G (0x80000000 - 0xffffffff) and processes using the lower
- 2G (0x00000000 - 0x7fffffff).
-
-
-
-
-4.2. The problem
------------------
-
-
- The prebuilt UML binaries on this site will not run on 2G/2G hosts
- because UML occupies the upper .5G of the 3G process address space
- (0xa0000000 - 0xbfffffff). Obviously, on 2G/2G hosts, this is right
- in the middle of the kernel address space, so UML won't even load - it
- will immediately segfault.
-
-
-
-
-4.3. The solution
-------------------
-
-
- The fix for this is to rebuild UML from source after enabling
- CONFIG_HOST_2G_2G (under 'General Setup'). This will cause UML to
- load itself in the top .5G of that smaller process address space,
- where it will run fine. See :ref:`Compiling_the_kernel_and_modules` if
- you need help building UML from source.

-
-
-5. Setting up serial lines and consoles
-========================================
-
-
- It is possible to attach UML serial lines and consoles to many types
- of host I/O channels by specifying them on the command line.
-
-
- You can attach them to host ptys, ttys, file descriptors, and ports.
- This allows you to do things like:
-
- - have a UML console appear on an unused host console,
-
- - hook two virtual machines together by having one attach to a pty
- and having the other attach to the corresponding tty
-
- - make a virtual machine accessible from the net by attaching a
- console to a port on the host.
-
-
- The general format of the command line option is ``device=channel``.
-
-
-
-5.1. Specifying the device
----------------------------
-
- Devices are specified with "con" or "ssl" (console or serial line,
- respectively), optionally with a device number if you are talking
- about a specific device.
-
-
- Using just "con" or "ssl" describes all of the consoles or serial
- lines. If you want to talk about console #3 or serial line #10, they
- would be "con3" and "ssl10", respectively.
-
-
- A specific device name will override a less general "con=" or "ssl=".
- So, for example, you can assign a pty to each of the serial lines
- except for the first two like this::
-
-
- ssl=pty ssl0=tty:/dev/tty0 ssl1=tty:/dev/tty1
-
-
-
-
- The specificity of the device name is all that matters; order on the
- command line is irrelevant.
-
-
-
-5.2. Specifying the channel
-----------------------------
-
- There are a number of different types of channels to attach a UML
- device to, each with a different way of specifying exactly what to
- attach to.
-
- - pseudo-terminals - device=pty pts terminals - device=pts
-
-
- This will cause UML to allocate a free host pseudo-terminal for the
- device. The terminal that it got will be announced in the boot
- log. You access it by attaching a terminal program to the
- corresponding tty:
-
- - screen /dev/pts/n
-
- - screen /dev/ttyxx
-
- - minicom -o -p /dev/ttyxx - minicom seems not able to handle pts
- devices
-
- - kermit - start it up, 'open' the device, then 'connect'
-
-
-
-
-
- - terminals - device=tty:tty device file
-
-
- This will make UML attach the device to the specified tty (i.e::
-
-
- con1=tty:/dev/tty3
-
-
-
-
- will attach UML's console 1 to the host's /dev/tty3). If the tty that
- you specify is the slave end of a tty/pty pair, something else must
- have already opened the corresponding pty in order for this to work.
-
-
-
-
-
- - xterms - device=xterm
-
-
- UML will run an xterm and the device will be attached to it.
-
-
-
-
-
- - Port - device=port:port number
-
-
- This will attach the UML devices to the specified host port.
- Attaching console 1 to the host's port 9000 would be done like
- this::
-
-
- con1=port:9000
-
-
-
-
- Attaching all the serial lines to that port would be done similarly::
-
-
- ssl=port:9000
-
-
-
-
- You access these devices by telnetting to that port. Each active
- telnet session gets a different device. If there are more telnets to a
- port than UML devices attached to it, then the extra telnet sessions
- will block until an existing telnet detaches, or until another device
- becomes active (i.e. by being activated in /etc/inittab).
-
- This channel has the advantage that you can both attach multiple UML
- devices to it and know how to access them without reading the UML boot
- log. It is also unique in allowing access to a UML from remote
- machines without requiring that the UML be networked. This could be
- useful in allowing public access to UMLs because they would be
- accessible from the net, but wouldn't need any kind of network
- filtering or access control because they would have no network access.
-
-
- If you attach the main console to a portal, then the UML boot will
- appear to hang. In reality, it's waiting for a telnet to connect, at
- which point the boot will proceed.
-
-
-
-
-
- - already-existing file descriptors - device=file descriptor
-
-
- If you set up a file descriptor on the UML command line, you can
- attach a UML device to it. This is most commonly used to put the
- main console back on stdin and stdout after assigning all the other
- consoles to something else::
-
-
- con0=fd:0,fd:1 con=pts
-
-
-
-
-
-
-
-
- - Nothing - device=null
-
-
- This allows the device to be opened, in contrast to 'none', but
- reads will block, and writes will succeed and the data will be
- thrown out.
-
-
-
-
-
- - None - device=none
-
-
- This causes the device to disappear.
-
-
-
- You can also specify different input and output channels for a device
- by putting a comma between them::
-
-
- ssl3=tty:/dev/tty2,xterm
-
-
-
-
- will cause serial line 3 to accept input on the host's /dev/tty2 and
- display output on an xterm. That's a silly example - the most common
- use of this syntax is to reattach the main console to stdin and stdout
- as shown above.
-
-
- If you decide to move the main console away from stdin/stdout, the
- initial boot output will appear in the terminal that you're running
- UML in. However, once the console driver has been officially
- initialized, then the boot output will start appearing wherever you
- specified that console 0 should be. That device will receive all
- subsequent output.
-
-
-
-5.3. Examples
---------------
-
- There are a number of interesting things you can do with this
- capability.
-
-
- First, this is how you get rid of those bleeding console xterms by
- attaching them to host ptys::
-
-
- con=pty con0=fd:0,fd:1
-
-
-
-
- This will make a UML console take over an unused host virtual console,
- so that when you switch to it, you will see the UML login prompt
- rather than the host login prompt::
-
-
- con1=tty:/dev/tty6
-
-
-
-
- You can attach two virtual machines together with what amounts to a
- serial line as follows:
-
- Run one UML with a serial line attached to a pty::
-
-
- ssl1=pty
-
-
-
-
- Look at the boot log to see what pty it got (this example will assume
- that it got /dev/ptyp1).
-
- Boot the other UML with a serial line attached to the corresponding
- tty::
-
-
- ssl1=tty:/dev/ttyp1
-
-
-
-
- Log in, make sure that it has no getty on that serial line, attach a
- terminal program like minicom to it, and you should see the login
- prompt of the other virtual machine.
-
-
-.. _setting_up_the_network:
-
-6. Setting up the network
-==========================
-
-
-
- This page describes how to set up the various transports and to
- provide a UML instance with network access to the host, other machines
- on the local net, and the rest of the net.
-
-
- As of 2.4.5, UML networking has been completely redone to make it much
- easier to set up, fix bugs, and add new features.
-
-
- There is a new helper, uml_net, which does the host setup that
- requires root privileges.
-
-
- There are currently five transport types available for a UML virtual
- machine to exchange packets with other hosts:
-
- - ethertap
-
- - TUN/TAP
-
- - Multicast
-
- - a switch daemon
-
- - slip
-
- - slirp
-
- - pcap
-
- The TUN/TAP, ethertap, slip, and slirp transports allow a UML
- instance to exchange packets with the host. They may be directed
- to the host or the host may just act as a router to provide access
- to other physical or virtual machines.
-
-
- The pcap transport is a synthetic read-only interface, using the
- libpcap binary to collect packets from interfaces on the host and
- filter them. This is useful for building preconfigured traffic
- monitors or sniffers.
-
-
- The daemon and multicast transports provide a completely virtual
- network to other virtual machines. This network is completely
- disconnected from the physical network unless one of the virtual
- machines on it is acting as a gateway.
-
-
- With so many host transports, which one should you use? Here's when
- you should use each one:
-
- - ethertap - if you want access to the host networking and it is
- running 2.2
-
- - TUN/TAP - if you want access to the host networking and it is
- running 2.4. Also, the TUN/TAP transport is able to use a
- preconfigured device, allowing it to avoid using the setuid uml_net
- helper, which is a security advantage.
-
- - Multicast - if you want a purely virtual network and you don't want
- to set up anything but the UML
-
- - a switch daemon - if you want a purely virtual network and you
- don't mind running the daemon in order to get somewhat better
- performance
-
- - slip - there is no particular reason to run the slip backend unless
- ethertap and TUN/TAP are just not available for some reason
-
- - slirp - if you don't have root access on the host to setup
- networking, or if you don't want to allocate an IP to your UML
-
- - pcap - not much use for actual network connectivity, but great for
- monitoring traffic on the host
-
- Ethertap is available on 2.4 and works fine. TUN/TAP is preferred
- to it because it has better performance and ethertap is officially
- considered obsolete in 2.4. Also, the root helper only needs to
- run occasionally for TUN/TAP, rather than handling every packet, as
- it does with ethertap. This is a slight security advantage since
- it provides fewer opportunities for a nasty UML user to somehow
- exploit the helper's root privileges.
-
-
-6.1. General setup
--------------------
-
- First, you must have the virtual network enabled in your UML. If are
- running a prebuilt kernel from this site, everything is already
- enabled. If you build the kernel yourself, under the "Network device
- support" menu, enable "Network device support", and then the three
- transports.
-
-
- The next step is to provide a network device to the virtual machine.
- This is done by describing it on the kernel command line.
-
- The general format is::
-
-
- eth <n> = <transport> , <transport args>
-
-
-
-
- For example, a virtual ethernet device may be attached to a host
- ethertap device as follows::
-
-
- eth0=ethertap,tap0,fe:fd:0:0:0:1,192.168.0.254
-
-
-
-
- This sets up eth0 inside the virtual machine to attach itself to the
- host /dev/tap0, assigns it an ethernet address, and assigns the host
- tap0 interface an IP address.
-
-
-
- Note that the IP address you assign to the host end of the tap device
- must be different than the IP you assign to the eth device inside UML.
- If you are short on IPs and don't want to consume two per UML, then
- you can reuse the host's eth IP address for the host ends of the tap
- devices. Internally, the UMLs must still get unique IPs for their eth
- devices. You can also give the UMLs non-routable IPs (192.168.x.x or
- 10.x.x.x) and have the host masquerade them. This will let outgoing
- connections work, but incoming connections won't without more work,
- such as port forwarding from the host.
- Also note that when you configure the host side of an interface, it is
- only acting as a gateway. It will respond to pings sent to it
- locally, but is not useful to do that since it's a host interface.
- You are not talking to the UML when you ping that interface and get a
- response.
-
-
- You can also add devices to a UML and remove them at runtime. See the
- :ref:`The_Management_Console` page for details.
-
-
- The sections below describe this in more detail.
-
-
- Once you've decided how you're going to set up the devices, you boot
- UML, log in, configure the UML side of the devices, and set up routes
- to the outside world. At that point, you will be able to talk to any
- other machines, physical or virtual, on the net.
-
-
- If ifconfig inside UML fails and the network refuses to come up, run
- tell you what went wrong.
-
-
-
-6.2. Userspace daemons
------------------------
-
- You will likely need the setuid helper, or the switch daemon, or both.
- They are both installed with the RPM and deb, so if you've installed
- either, you can skip the rest of this section.
-
-
- If not, then you need to check them out of CVS, build them, and
- install them. The helper is uml_net, in CVS /tools/uml_net, and the
- daemon is uml_switch, in CVS /tools/uml_router. They are both built
- with a plain 'make'. Both need to be installed in a directory that's
- in your path - /usr/bin is recommend. On top of that, uml_net needs
- to be setuid root.
-
-
-
-6.3. Specifying ethernet addresses
------------------------------------
-
- Below, you will see that the TUN/TAP, ethertap, and daemon interfaces
- allow you to specify hardware addresses for the virtual ethernet
- devices. This is generally not necessary. If you don't have a
- specific reason to do it, you probably shouldn't. If one is not
- specified on the command line, the driver will assign one based on the
- device IP address. It will provide the address fe:fd:nn:nn:nn:nn
- where nn.nn.nn.nn is the device IP address. This is nearly always
- sufficient to guarantee a unique hardware address for the device. A
- couple of exceptions are:
-
- - Another set of virtual ethernet devices are on the same network and
- they are assigned hardware addresses using a different scheme which
- may conflict with the UML IP address-based scheme
-
- - You aren't going to use the device for IP networking, so you don't
- assign the device an IP address
-
- If you let the driver provide the hardware address, you should make
- sure that the device IP address is known before the interface is
- brought up. So, inside UML, this will guarantee that::
-
-
-
- UML#
- ifconfig eth0 192.168.0.250 up
-
-
-
-
- If you decide to assign the hardware address yourself, make sure that
- the first byte of the address is even. Addresses with an odd first
- byte are broadcast addresses, which you don't want assigned to a
- device.
-
-
-
-6.4. UML interface setup
--------------------------
-
- Once the network devices have been described on the command line, you
- should boot UML and log in.
-
-
- The first thing to do is bring the interface up::
-
-
- UML# ifconfig ethn ip-address up
-
-
-
-
- You should be able to ping the host at this point.
-
-
- To reach the rest of the world, you should set a default route to the
- host::
-
-
- UML# route add default gw host ip
-
-
-
-
- Again, with host ip of 192.168.0.4::
-
-
- UML# route add default gw 192.168.0.4
-
-
-
-
- This page used to recommend setting a network route to your local net.
- This is wrong, because it will cause UML to try to figure out hardware
- addresses of the local machines by arping on the interface to the
- host. Since that interface is basically a single strand of ethernet
- with two nodes on it (UML and the host) and arp requests don't cross
- networks, they will fail to elicit any responses. So, what you want
- is for UML to just blindly throw all packets at the host and let it
- figure out what to do with them, which is what leaving out the network
- route and adding the default route does.
-
-
- Note: If you can't communicate with other hosts on your physical
- ethernet, it's probably because of a network route that's
- automatically set up. If you run 'route -n' and see a route that
- looks like this::
-
-
-
-
- Destination Gateway Genmask Flags Metric Ref Use Iface
- 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
-
-
-
-
- with a mask that's not 255.255.255.255, then replace it with a route
- to your host::
-
-
- UML#
- route del -net 192.168.0.0 dev eth0 netmask 255.255.255.0
-
-
- UML#
- route add -host 192.168.0.4 dev eth0
-
-
-
-
- This, plus the default route to the host, will allow UML to exchange
- packets with any machine on your ethernet.
-
-
-
-6.5. Multicast
----------------
-
- The simplest way to set up a virtual network between multiple UMLs is
- to use the mcast transport. This was written by Harald Welte and is
- present in UML version 2.4.5-5um and later. Your system must have
- multicast enabled in the kernel and there must be a multicast-capable
- network device on the host. Normally, this is eth0, but if there is
- no ethernet card on the host, then you will likely get strange error
- messages when you bring the device up inside UML.
-
-
- To use it, run two UMLs with::
-
-
- eth0=mcast
-
-
-
-
- on their command lines. Log in, configure the ethernet device in each
- machine with different IP addresses::
-
-
- UML1# ifconfig eth0 192.168.0.254
-
-
- UML2# ifconfig eth0 192.168.0.253
-
-
-
-
- and they should be able to talk to each other.
-
- The full set of command line options for this transport are::
-
-
-
- ethn=mcast,ethernet address,multicast
- address,multicast port,ttl
-
-
-
- There is also a related point-to-point only "ucast" transport.
- This is useful when your network does not support multicast, and
- all network connections are simple point to point links.
-
- The full set of command line options for this transport are::
-
-
- ethn=ucast,ethernet address,remote address,listen port,remote port
-
-
-
-
-6.6. TUN/TAP with the uml_net helper
--------------------------------------
-
- TUN/TAP is the preferred mechanism on 2.4 to exchange packets with the
- host. The TUN/TAP backend has been in UML since 2.4.9-3um.
-
-
- The easiest way to get up and running is to let the setuid uml_net
- helper do the host setup for you. This involves insmod-ing the tun.o
- module if necessary, configuring the device, and setting up IP
- forwarding, routing, and proxy arp. If you are new to UML networking,
- do this first. If you're concerned about the security implications of
- the setuid helper, use it to get up and running, then read the next
- section to see how to have UML use a preconfigured tap device, which
- avoids the use of uml_net.
-
-
- If you specify an IP address for the host side of the device, the
- uml_net helper will do all necessary setup on the host - the only
- requirement is that TUN/TAP be available, either built in to the host
- kernel or as the tun.o module.
-
- The format of the command line switch to attach a device to a TUN/TAP
- device is::
-
-
- eth <n> =tuntap,,, <IP address>
-
-
-
-
- For example, this argument will attach the UML's eth0 to the next
- available tap device and assign an ethernet address to it based on its
- IP address::
-
-
- eth0=tuntap,,,192.168.0.254
-
-
-
-
-
-
- Note that the IP address that must be used for the eth device inside
- UML is fixed by the routing and proxy arp that is set up on the
- TUN/TAP device on the host. You can use a different one, but it won't
- work because reply packets won't reach the UML. This is a feature.
- It prevents a nasty UML user from doing things like setting the UML IP
- to the same as the network's nameserver or mail server.
-
-
- There are a couple potential problems with running the TUN/TAP
- transport on a 2.4 host kernel
-
- - TUN/TAP seems not to work on 2.4.3 and earlier. Upgrade the host
- kernel or use the ethertap transport.
-
- - With an upgraded kernel, TUN/TAP may fail with::
-
-
- File descriptor in bad state
-
-
-
-
- This is due to a header mismatch between the upgraded kernel and the
- kernel that was originally installed on the machine. The fix is to
- make sure that /usr/src/linux points to the headers for the running
- kernel.
-
- These were pointed out by Tim Robinson <timro at trkr dot net> in the past.
-
-
-
-6.7. TUN/TAP with a preconfigured tap device
----------------------------------------------
-
- If you prefer not to have UML use uml_net (which is somewhat
- insecure), with UML 2.4.17-11, you can set up a TUN/TAP device
- beforehand. The setup needs to be done as root, but once that's done,
- there is no need for root assistance. Setting up the device is done
- as follows:
-
- - Create the device with tunctl (available from the UML utilities
- tarball)::
-
-
-
-
- host# tunctl -u uid
-
-
-
-
- where uid is the user id or username that UML will be run as. This
- will tell you what device was created.
-
- - Configure the device IP (change IP addresses and device name to
- suit)::
-
-
-
-
- host# ifconfig tap0 192.168.0.254 up
-
-
-
-
-
- - Set up routing and arping if desired - this is my recipe, there are
- other ways of doing the same thing::
-
-
- host#
- bash -c 'echo 1 > /proc/sys/net/ipv4/ip_forward'
-
- host#
- route add -host 192.168.0.253 dev tap0
-
- host#
- bash -c 'echo 1 > /proc/sys/net/ipv4/conf/tap0/proxy_arp'
-
- host#
- arp -Ds 192.168.0.253 eth0 pub
-
-
-
-
- Note that this must be done every time the host boots - this configu-
- ration is not stored across host reboots. So, it's probably a good
- idea to stick it in an rc file. An even better idea would be a little
- utility which reads the information from a config file and sets up
- devices at boot time.
-
- - Rather than using up two IPs and ARPing for one of them, you can
- also provide direct access to your LAN by the UML by using a
- bridge::
-
-
- host#
- brctl addbr br0
-
-
- host#
- ifconfig eth0 0.0.0.0 promisc up
-
-
- host#
- ifconfig tap0 0.0.0.0 promisc up
-
-
- host#
- ifconfig br0 192.168.0.1 netmask 255.255.255.0 up
-
-
- host#
- brctl stp br0 off
-
-
- host#
- brctl setfd br0 1
-
-
- host#
- brctl sethello br0 1
-
-
- host#
- brctl addif br0 eth0
-
-
- host#
- brctl addif br0 tap0
-
-
-
-
- Note that 'br0' should be setup using ifconfig with the existing IP
- address of eth0, as eth0 no longer has its own IP.
-
- -
-
-
- Also, the /dev/net/tun device must be writable by the user running
- UML in order for the UML to use the device that's been configured
- for it. The simplest thing to do is::
-
-
- host# chmod 666 /dev/net/tun
-
-
-
-
- Making it world-writable looks bad, but it seems not to be
- exploitable as a security hole. However, it does allow anyone to cre-
- ate useless tap devices (useless because they can't configure them),
- which is a DOS attack. A somewhat more secure alternative would to be
- to create a group containing all the users who have preconfigured tap
- devices and chgrp /dev/net/tun to that group with mode 664 or 660.
-
-
- - Once the device is set up, run UML with 'eth0=tuntap,device name'
- (i.e. 'eth0=tuntap,tap0') on the command line (or do it with the
- mconsole config command).
-
- - Bring the eth device up in UML and you're in business.
-
- If you don't want that tap device any more, you can make it non-
- persistent with::
-
-
- host# tunctl -d tap device
-
-
-
-
- Finally, tunctl has a -b (for brief mode) switch which causes it to
- output only the name of the tap device it created. This makes it
- suitable for capture by a script::
-
-
- host# TAP=`tunctl -u 1000 -b`
-
-
-
-
-
-
-6.8. Ethertap
---------------
-
- Ethertap is the general mechanism on 2.2 for userspace processes to
- exchange packets with the kernel.
-
-
-
- To use this transport, you need to describe the virtual network device
- on the UML command line. The general format for this is::
-
-
- eth <n> =ethertap, <device> , <ethernet address> , <tap IP address>
-
-
-
-
- So, the previous example::
-
-
- eth0=ethertap,tap0,fe:fd:0:0:0:1,192.168.0.254
-
-
-
-
- attaches the UML eth0 device to the host /dev/tap0, assigns it the
- ethernet address fe:fd:0:0:0:1, and assigns the IP address
- 192.168.0.254 to the tap device.
-
-
-
- The tap device is mandatory, but the others are optional. If the
- ethernet address is omitted, one will be assigned to it.
-
-
- The presence of the tap IP address will cause the helper to run and do
- whatever host setup is needed to allow the virtual machine to
- communicate with the outside world. If you're not sure you know what
- you're doing, this is the way to go.
-
-
- If it is absent, then you must configure the tap device and whatever
- arping and routing you will need on the host. However, even in this
- case, the uml_net helper still needs to be in your path and it must be
- setuid root if you're not running UML as root. This is because the
- tap device doesn't support SIGIO, which UML needs in order to use
- something as a source of input. So, the helper is used as a
- convenient asynchronous IO thread.
-
- If you're using the uml_net helper, you can ignore the following host
- setup - uml_net will do it for you. You just need to make sure you
- have ethertap available, either built in to the host kernel or
- available as a module.
-
-
- If you want to set things up yourself, you need to make sure that the
- appropriate /dev entry exists. If it doesn't, become root and create
- it as follows::
-
-
- mknod /dev/tap <minor> c 36 <minor> + 16
-
-
-
-
- For example, this is how to create /dev/tap0::
-
-
- mknod /dev/tap0 c 36 0 + 16
-
-
-
-
- You also need to make sure that the host kernel has ethertap support.
- If ethertap is enabled as a module, you apparently need to insmod
- ethertap once for each ethertap device you want to enable. So,::
-
-
- host#
- insmod ethertap
-
-
-
-
- will give you the tap0 interface. To get the tap1 interface, you need
- to run::
-
-
- host#
- insmod ethertap unit=1 -o ethertap1
-
-
-
-
-
-
-
-6.9. The switch daemon
------------------------
-
- Note: This is the daemon formerly known as uml_router, but which was
- renamed so the network weenies of the world would stop growling at me.
-
-
- The switch daemon, uml_switch, provides a mechanism for creating a
- totally virtual network. By default, it provides no connection to the
- host network (but see -tap, below).
-
-
- The first thing you need to do is run the daemon. Running it with no
- arguments will make it listen on a default pair of unix domain
- sockets.
-
-
- If you want it to listen on a different pair of sockets, use::
-
-
- -unix control socket data socket
-
-
-
-
-
- If you want it to act as a hub rather than a switch, use::
-
-
- -hub
-
-
-
-
-
- If you want the switch to be connected to host networking (allowing
- the umls to get access to the outside world through the host), use::
-
-
- -tap tap0
-
-
-
-
-
- Note that the tap device must be preconfigured (see "TUN/TAP with a
- preconfigured tap device", above). If you're using a different tap
- device than tap0, specify that instead of tap0.
-
-
- uml_switch can be backgrounded as follows::
-
-
- host%
- uml_switch [ options ] < /dev/null > /dev/null
-
-
-
-
- The reason it doesn't background by default is that it listens to
- stdin for EOF. When it sees that, it exits.
-
-
- The general format of the kernel command line switch is::
-
-
-
- ethn=daemon,ethernet address,socket
- type,control socket,data socket
-
-
-
-
- You can leave off everything except the 'daemon'. You only need to
- specify the ethernet address if the one that will be assigned to it
- isn't acceptable for some reason. The rest of the arguments describe
- how to communicate with the daemon. You should only specify them if
- you told the daemon to use different sockets than the default. So, if
- you ran the daemon with no arguments, running the UML on the same
- machine with::
-
- eth0=daemon
-
-
-
-
- will cause the eth0 driver to attach itself to the daemon correctly.
-
-
-
-6.10. Slip
------------
-
- Slip is another, less general, mechanism for a process to communicate
- with the host networking. In contrast to the ethertap interface,
- which exchanges ethernet frames with the host and can be used to
- transport any higher-level protocol, it can only be used to transport
- IP.
-
-
- The general format of the command line switch is::
-
-
-
- ethn=slip,slip IP
-
-
-
-
- The slip IP argument is the IP address that will be assigned to the
- host end of the slip device. If it is specified, the helper will run
- and will set up the host so that the virtual machine can reach it and
- the rest of the network.
-
-
- There are some oddities with this interface that you should be aware
- of. You should only specify one slip device on a given virtual
- machine, and its name inside UML will be 'umn', not 'eth0' or whatever
- you specified on the command line. These problems will be fixed at
- some point.
-
-
-
-6.11. Slirp
-------------
-
- slirp uses an external program, usually /usr/bin/slirp, to provide IP
- only networking connectivity through the host. This is similar to IP
- masquerading with a firewall, although the translation is performed in
- user-space, rather than by the kernel. As slirp does not set up any
- interfaces on the host, or changes routing, slirp does not require
- root access or setuid binaries on the host.
-
-
- The general format of the command line switch for slirp is::
-
-
-
- ethn=slirp,ethernet address,slirp path
-
-
-
-
- The ethernet address is optional, as UML will set up the interface
- with an ethernet address based upon the initial IP address of the
- interface. The slirp path is generally /usr/bin/slirp, although it
- will depend on distribution.
-
-
- The slirp program can have a number of options passed to the command
- line and we can't add them to the UML command line, as they will be
- parsed incorrectly. Instead, a wrapper shell script can be written or
- the options inserted into the /.slirprc file. More information on
- all of the slirp options can be found in its man pages.
-
-
- The eth0 interface on UML should be set up with the IP 10.2.0.15,
- although you can use anything as long as it is not used by a network
- you will be connecting to. The default route on UML should be set to
- use::
-
-
- UML#
- route add default dev eth0
-
-
-
-
- slirp provides a number of useful IP addresses which can be used by
- UML, such as 10.0.2.3 which is an alias for the DNS server specified
- in /etc/resolv.conf on the host or the IP given in the 'dns' option
- for slirp.
-
-
- Even with a baudrate setting higher than 115200, the slirp connection
- is limited to 115200. If you need it to go faster, the slirp binary
- needs to be compiled with FULL_BOLT defined in config.h.
-
-
-
-6.12. pcap
------------
-
- The pcap transport is attached to a UML ethernet device on the command
- line or with uml_mconsole with the following syntax::
-
-
-
- ethn=pcap,host interface,filter
- expression,option1,option2
-
-
-
-
- The expression and options are optional.
-
-
- The interface is whatever network device on the host you want to
- sniff. The expression is a pcap filter expression, which is also what
- tcpdump uses, so if you know how to specify tcpdump filters, you will
- use the same expressions here. The options are up to two of
- 'promisc', control whether pcap puts the host interface into
- promiscuous mode. 'optimize' and 'nooptimize' control whether the pcap
- expression optimizer is used.
-
-
- Example::
-
-
-
- eth0=pcap,eth0,tcp
-
- eth1=pcap,eth0,!tcp
-
-
-
- will cause the UML eth0 to emit all tcp packets on the host eth0 and
- the UML eth1 to emit all non-tcp packets on the host eth0.
-
-
-
-6.13. Setting up the host yourself
------------------------------------
-
- If you don't specify an address for the host side of the ethertap or
- slip device, UML won't do any setup on the host. So this is what is
- needed to get things working (the examples use a host-side IP of
- 192.168.0.251 and a UML-side IP of 192.168.0.250 - adjust to suit your
- own network):
-
- - The device needs to be configured with its IP address. Tap devices
- are also configured with an mtu of 1484. Slip devices are
- configured with a point-to-point address pointing at the UML ip
- address::
-
-
- host# ifconfig tap0 arp mtu 1484 192.168.0.251 up
-
-
- host#
- ifconfig sl0 192.168.0.251 pointopoint 192.168.0.250 up
-
-
-
-
-
- - If a tap device is being set up, a route is set to the UML IP::
-
-
- UML# route add -host 192.168.0.250 gw 192.168.0.251
-
-
-
-
-
- - To allow other hosts on your network to see the virtual machine,
- proxy arp is set up for it::
-
-
- host# arp -Ds 192.168.0.250 eth0 pub
-
-
-
-
-
- - Finally, the host is set up to route packets::
-
-
- host# echo 1 > /proc/sys/net/ipv4/ip_forward
-
-
-
-
-
-
-
-
-
-
-7. Sharing Filesystems between Virtual Machines
-================================================
-
-
-
-
-7.1. A warning
----------------
-
- Don't attempt to share filesystems simply by booting two UMLs from the
- same file. That's the same thing as booting two physical machines
- from a shared disk. It will result in filesystem corruption.
-
-
-
-7.2. Using layered block devices
----------------------------------
-
- The way to share a filesystem between two virtual machines is to use
- the copy-on-write (COW) layering capability of the ubd block driver.
- As of 2.4.6-2um, the driver supports layering a read-write private
- device over a read-only shared device. A machine's writes are stored
- in the private device, while reads come from either device - the
- private one if the requested block is valid in it, the shared one if
- not. Using this scheme, the majority of data which is unchanged is
- shared between an arbitrary number of virtual machines, each of which
- has a much smaller file containing the changes that it has made. With
- a large number of UMLs booting from a large root filesystem, this
- leads to a huge disk space saving. It will also help performance,
- since the host will be able to cache the shared data using a much
- smaller amount of memory, so UML disk requests will be served from the
- host's memory rather than its disks.
-
-
-
-
- To add a copy-on-write layer to an existing block device file, simply
- add the name of the COW file to the appropriate ubd switch::
-
-
- ubd0=root_fs_cow,root_fs_debian_22
-
-
-
-
- where 'root_fs_cow' is the private COW file and 'root_fs_debian_22' is
- the existing shared filesystem. The COW file need not exist. If it
- doesn't, the driver will create and initialize it. Once the COW file
- has been initialized, it can be used on its own on the command line::
-
-
- ubd0=root_fs_cow
-
-
-
-
- The name of the backing file is stored in the COW file header, so it
- would be redundant to continue specifying it on the command line.
-
-
-
-7.3. Note!
------------
-
- When checking the size of the COW file in order to see the gobs of
- space that you're saving, make sure you use 'ls -ls' to see the actual
- disk consumption rather than the length of the file. The COW file is
- sparse, so the length will be very different from the disk usage.
- Here is a 'ls -l' of a COW file and backing file from one boot and
- shutdown::
-
- host% ls -l cow.debian debian2.2
- -rw-r--r-- 1 jdike jdike 492504064 Aug 6 21:16 cow.debian
- -rwxrw-rw- 1 jdike jdike 537919488 Aug 6 20:42 debian2.2
-
-
-
-
- Doesn't look like much saved space, does it? Well, here's 'ls -ls'::
-
-
- host% ls -ls cow.debian debian2.2
- 880 -rw-r--r-- 1 jdike jdike 492504064 Aug 6 21:16 cow.debian
- 525832 -rwxrw-rw- 1 jdike jdike 537919488 Aug 6 20:42 debian2.2
-
-
-
-
- Now, you can see that the COW file has less than a meg of disk, rather
- than 492 meg.
-
-
-
-7.4. Another warning
----------------------
-
- Once a filesystem is being used as a readonly backing file for a COW
- file, do not boot directly from it or modify it in any way. Doing so
- will invalidate any COW files that are using it. The mtime and size
- of the backing file are stored in the COW file header at its creation,
- and they must continue to match. If they don't, the driver will
- refuse to use the COW file.
-
-
-
-
- If you attempt to evade this restriction by changing either the
- backing file or the COW header by hand, you will get a corrupted
- filesystem.
-
-
-
-
- Among other things, this means that upgrading the distribution in a
- backing file and expecting that all of the COW files using it will see
- the upgrade will not work.
-
-
-
-
-7.5. uml_moo : Merging a COW file with its backing file
---------------------------------------------------------
-
- Depending on how you use UML and COW devices, it may be advisable to
- merge the changes in the COW file into the backing file every once in
- a while.
-
-
-
-
- The utility that does this is uml_moo. Its usage is::
-
-
- host% uml_moo COW file new backing file
-
-
-
-
- There's no need to specify the backing file since that information is
- already in the COW file header. If you're paranoid, boot the new
- merged file, and if you're happy with it, move it over the old backing
- file.
-
-
-
-
- uml_moo creates a new backing file by default as a safety measure. It
- also has a destructive merge option which will merge the COW file
- directly into its current backing file. This is really only usable
- when the backing file only has one COW file associated with it. If
- there are multiple COWs associated with a backing file, a -d merge of
- one of them will invalidate all of the others. However, it is
- convenient if you're short of disk space, and it should also be
- noticeably faster than a non-destructive merge.
-
-
-
-
- uml_moo is installed with the UML deb and RPM. If you didn't install
- UML from one of those packages, you can also get it from the UML
- utilities http://user-mode-linux.sourceforge.net/utilities tar file
- in tools/moo.
-
-
-
-
-
-
-
-
-8. Creating filesystems
-========================
-
-
- You may want to create and mount new UML filesystems, either because
- your root filesystem isn't large enough or because you want to use a
- filesystem other than ext2.
-
-
- This was written on the occasion of reiserfs being included in the
- 2.4.1 kernel pool, and therefore the 2.4.1 UML, so the examples will
- talk about reiserfs. This information is generic, and the examples
- should be easy to translate to the filesystem of your choice.
-
-
-8.1. Create the filesystem file
-================================
-
- dd is your friend. All you need to do is tell dd to create an empty
- file of the appropriate size. I usually make it sparse to save time
- and to avoid allocating disk space until it's actually used. For
- example, the following command will create a sparse 100 meg file full
- of zeroes::
-
-
- host%
- dd if=/dev/zero of=new_filesystem seek=100 count=1 bs=1M
-
-
-
-
-
-
- 8.2. Assign the file to a UML device
-
- Add an argument like the following to the UML command line::
-
- ubd4=new_filesystem
-
-
-
-
- making sure that you use an unassigned ubd device number.
-
-
-
- 8.3. Creating and mounting the filesystem
-
- Make sure that the filesystem is available, either by being built into
- the kernel, or available as a module, then boot up UML and log in. If
- the root filesystem doesn't have the filesystem utilities (mkfs, fsck,
- etc), then get them into UML by way of the net or hostfs.
-
-
- Make the new filesystem on the device assigned to the new file::
-
-
- host# mkreiserfs /dev/ubd/4
-
-
- <----------- MKREISERFSv2 ----------->
-
- ReiserFS version 3.6.25
- Block size 4096 bytes
- Block count 25856
- Used blocks 8212
- Journal - 8192 blocks (18-8209), journal header is in block 8210
- Bitmaps: 17
- Root block 8211
- Hash function "r5"
- ATTENTION: ALL DATA WILL BE LOST ON '/dev/ubd/4'! (y/n)y
- journal size 8192 (from 18)
- Initializing journal - 0%....20%....40%....60%....80%....100%
- Syncing..done.
-
-
-
-
- Now, mount it::
-
-
- UML#
- mount /dev/ubd/4 /mnt
-
-
-
-
- and you're in business.
-
-
-
-
-
-
-
-
-
-9. Host file access
-====================
-
-
- If you want to access files on the host machine from inside UML, you
- can treat it as a separate machine and either nfs mount directories
- from the host or copy files into the virtual machine with scp or rcp.
- However, since UML is running on the host, it can access those
- files just like any other process and make them available inside the
- virtual machine without needing to use the network.
-
-
- This is now possible with the hostfs virtual filesystem. With it, you
- can mount a host directory into the UML filesystem and access the
- files contained in it just as you would on the host.
-
-
-9.1. Using hostfs
-------------------
-
- To begin with, make sure that hostfs is available inside the virtual
- machine with::
-
-
- UML# cat /proc/filesystems
-
-
-
- . hostfs should be listed. If it's not, either rebuild the kernel
- with hostfs configured into it or make sure that hostfs is built as a
- module and available inside the virtual machine, and insmod it.
-
-
- Now all you need to do is run mount::
-
-
- UML# mount none /mnt/host -t hostfs
-
-
-
-
- will mount the host's / on the virtual machine's /mnt/host.
-
-
- If you don't want to mount the host root directory, then you can
- specify a subdirectory to mount with the -o switch to mount::
-
-
- UML# mount none /mnt/home -t hostfs -o /home
-
-
-
-
- will mount the hosts's /home on the virtual machine's /mnt/home.
-
-
-
-9.2. hostfs as the root filesystem
------------------------------------
-
- It's possible to boot from a directory hierarchy on the host using
- hostfs rather than using the standard filesystem in a file.
-
- To start, you need that hierarchy. The easiest way is to loop mount
- an existing root_fs file::
-
-
- host# mount root_fs uml_root_dir -o loop
-
-
-
-
- You need to change the filesystem type of / in etc/fstab to be
- 'hostfs', so that line looks like this::
-
- /dev/ubd/0 / hostfs defaults 1 1
-
-
-
-
- Then you need to chown to yourself all the files in that directory
- that are owned by root. This worked for me::
-
-
- host# find . -uid 0 -exec chown jdike {} \;
-
-
-
-
- Next, make sure that your UML kernel has hostfs compiled in, not as a
- module. Then run UML with the boot device pointing at that directory::
-
-
- ubd0=/path/to/uml/root/directory
-
-
-
-
- UML should then boot as it does normally.
-
-
-9.3. Building hostfs
----------------------
-
- If you need to build hostfs because it's not in your kernel, you have
- two choices:
-
-
-
- - Compiling hostfs into the kernel:
-
-
- Reconfigure the kernel and set the 'Host filesystem' option under
-
-
- - Compiling hostfs as a module:
-
-
- Reconfigure the kernel and set the 'Host filesystem' option under
- be in arch/um/fs/hostfs/hostfs.o. Install that in
- ``/lib/modules/$(uname -r)/fs`` in the virtual machine, boot it up, and::
-
-
- UML# insmod hostfs
-
-
-.. _The_Management_Console:
-
-10. The Management Console
-===========================
-
-
-
- The UML management console is a low-level interface to the kernel,
- somewhat like the i386 SysRq interface. Since there is a full-blown
- operating system under UML, there is much greater flexibility possible
- than with the SysRq mechanism.
-
-
- There are a number of things you can do with the mconsole interface:
-
- - get the kernel version
-
- - add and remove devices
-
- - halt or reboot the machine
-
- - Send SysRq commands
-
- - Pause and resume the UML
-
-
- You need the mconsole client (uml_mconsole) which is present in CVS
- (/tools/mconsole) in 2.4.5-9um and later, and will be in the RPM in
- 2.4.6.
-
-
- You also need CONFIG_MCONSOLE (under 'General Setup') enabled in UML.
- When you boot UML, you'll see a line like::
-
-
- mconsole initialized on /home/jdike/.uml/umlNJ32yL/mconsole
-
-
-
-
- If you specify a unique machine id one the UML command line, i.e.::
-
-
- umid=debian
-
-
-
-
- you'll see this::
-
-
- mconsole initialized on /home/jdike/.uml/debian/mconsole
-
-
-
-
- That file is the socket that uml_mconsole will use to communicate with
- UML. Run it with either the umid or the full path as its argument::
-
-
- host% uml_mconsole debian
-
-
-
-
- or::
-
-
- host% uml_mconsole /home/jdike/.uml/debian/mconsole
-
-
-
-
- You'll get a prompt, at which you can run one of these commands:
-
- - version
-
- - halt
-
- - reboot
-
- - config
-
- - remove
-
- - sysrq
-
- - help
-
- - cad
-
- - stop
-
- - go
-
-
-10.1. version
---------------
-
- This takes no arguments. It prints the UML version::
-
-
- (mconsole) version
- OK Linux usermode 2.4.5-9um #1 Wed Jun 20 22:47:08 EDT 2001 i686
-
-
-
-
- There are a couple actual uses for this. It's a simple no-op which
- can be used to check that a UML is running. It's also a way of
- sending an interrupt to the UML. This is sometimes useful on SMP
- hosts, where there's a bug which causes signals to UML to be lost,
- often causing it to appear to hang. Sending such a UML the mconsole
- version command is a good way to 'wake it up' before networking has
- been enabled, as it does not do anything to the function of the UML.
-
-
-
-10.2. halt and reboot
-----------------------
-
- These take no arguments. They shut the machine down immediately, with
- no syncing of disks and no clean shutdown of userspace. So, they are
- pretty close to crashing the machine::
-
-
- (mconsole) halt
- OK
-
-
-
-
-
-
-10.3. config
--------------
-
- "config" adds a new device to the virtual machine. Currently the ubd
- and network drivers support this. It takes one argument, which is the
- device to add, with the same syntax as the kernel command line::
-
-
-
-
- (mconsole)
- config ubd3=/home/jdike/incoming/roots/root_fs_debian22
-
- OK
- (mconsole) config eth1=mcast
- OK
-
-
-
-
-
-
-10.4. remove
--------------
-
- "remove" deletes a device from the system. Its argument is just the
- name of the device to be removed. The device must be idle in whatever
- sense the driver considers necessary. In the case of the ubd driver,
- the removed block device must not be mounted, swapped on, or otherwise
- open, and in the case of the network driver, the device must be down::
-
-
- (mconsole) remove ubd3
- OK
- (mconsole) remove eth1
- OK
-
-
-
-
-
-
-10.5. sysrq
-------------
-
- This takes one argument, which is a single letter. It calls the
- generic kernel's SysRq driver, which does whatever is called for by
- that argument. See the SysRq documentation in
- Documentation/admin-guide/sysrq.rst in your favorite kernel tree to
- see what letters are valid and what they do.
-
-
-
-10.6. help
------------
-
- "help" returns a string listing the valid commands and what each one
- does.
-
-
-
-10.7. cad
-----------
-
- This invokes the Ctl-Alt-Del action on init. What exactly this ends
- up doing is up to /etc/inittab. Normally, it reboots the machine.
- With UML, this is usually not desired, so if a halt would be better,
- then find the section of inittab that looks like this::
-
-
- # What to do when CTRL-ALT-DEL is pressed.
- ca:12345:ctrlaltdel:/sbin/shutdown -t1 -a -r now
-
-
-
-
- and change the command to halt.

-
-10.8. stop
------------
-
- This puts the UML in a loop reading mconsole requests until a 'go'
- mconsole command is received. This is very useful for making backups
- of UML filesystems, as the UML can be stopped, then synced via 'sysrq
- s', so that everything is written to the filesystem. You can then copy
- the filesystem and then send the UML 'go' via mconsole.
-
-
- Note that a UML running with more than one CPU will have problems
- after you send the 'stop' command, as only one CPU will be held in a
- mconsole loop and all others will continue as normal. This is a bug,
- and will be fixed.
-
-
-
-10.9. go
----------
-
- This resumes a UML after being paused by a 'stop' command. Note that
- when the UML has resumed, TCP connections may have timed out and if
- the UML is paused for a long period of time, crond might go a little
- crazy, running all the jobs it didn't do earlier.

-.. _Kernel_debugging:
-
-11. Kernel debugging
-=====================
-
-
- Note: The interface that makes debugging, as described here, possible
- is present in 2.4.0-test6 kernels and later.
-
-
- Since the user-mode kernel runs as a normal Linux process, it is
- possible to debug it with gdb almost like any other process. It is
- slightly different because the kernel's threads are already being
- ptraced for system call interception, so gdb can't ptrace them.
- However, a mechanism has been added to work around that problem.
-
-
- In order to debug the kernel, you need build it from source. See
- :ref:`Compiling_the_kernel_and_modules` for information on doing that.
- Make sure that you enable CONFIG_DEBUGSYM and CONFIG_PT_PROXY during
- the config. These will compile the kernel with ``-g``, and enable the
- ptrace proxy so that gdb works with UML, respectively.
-
-
-
-
-11.1. Starting the kernel under gdb
-------------------------------------
-
- You can have the kernel running under the control of gdb from the
- beginning by putting 'debug' on the command line. You will get an
- xterm with gdb running inside it. The kernel will send some commands
- to gdb which will leave it stopped at the beginning of start_kernel.
- At this point, you can get things going with 'next', 'step', or
- 'cont'.
-
-
- There is a transcript of a debugging session here <debug-
- session.html> , with breakpoints being set in the scheduler and in an
- interrupt handler.
-
-
-11.2. Examining sleeping processes
------------------------------------
-
-
- Not every bug is evident in the currently running process. Sometimes,
- processes hang in the kernel when they shouldn't because they've
- deadlocked on a semaphore or something similar. In this case, when
- you ^C gdb and get a backtrace, you will see the idle thread, which
- isn't very relevant.
-
-
- What you want is the stack of whatever process is sleeping when it
- shouldn't be. You need to figure out which process that is, which is
- generally fairly easy. Then you need to get its host process id,
- which you can do either by looking at ps on the host or at
- task.thread.extern_pid in gdb.
-
-
- Now what you do is this:
-
- - detach from the current thread::
-
-
- (UML gdb) det
-
-
-
-
-
- - attach to the thread you are interested in::
-
-
- (UML gdb) att <host pid>
-
-
-
-
-
- - look at its stack and anything else of interest::
-
-
- (UML gdb) bt
-
-
-
-
- Note that you can't do anything at this point that requires that a
- process execute, e.g. calling a function
-
- - when you're done looking at that process, reattach to the current
- thread and continue it::
-
-
- (UML gdb)
- att 1
-
-
- (UML gdb)
- c
-
-
-
-
- Here, specifying any pid which is not the process id of a UML thread
- will cause gdb to reattach to the current thread. I commonly use 1,
- but any other invalid pid would work.
-
-
-
-11.3. Running ddd on UML
--------------------------
-
- ddd works on UML, but requires a special kludge. The process goes
- like this:
-
- - Start ddd::
-
-
- host% ddd linux
-
-
-
-
-
- - With ps, get the pid of the gdb that ddd started. You can ask the
- gdb to tell you, but for some reason that confuses things and
- causes a hang.
-
- - run UML with 'debug=parent gdb-pid=<pid>' added to the command line
- - it will just sit there after you hit return
-
- - type 'att 1' to the ddd gdb and you will see something like::
-
-
- 0xa013dc51 in __kill ()
-
-
- (gdb)
-
-
-
-
-
- - At this point, type 'c', UML will boot up, and you can use ddd just
- as you do on any other process.
-
-
-
-11.4. Debugging modules
-------------------------
-
-
- gdb has support for debugging code which is dynamically loaded into
- the process. This support is what is needed to debug kernel modules
- under UML.
-
-
- Using that support is somewhat complicated. You have to tell gdb what
- object file you just loaded into UML and where in memory it is. Then,
- it can read the symbol table, and figure out where all the symbols are
- from the load address that you provided. It gets more interesting
- when you load the module again (i.e. after an rmmod). You have to
- tell gdb to forget about all its symbols, including the main UML ones
- for some reason, then load then all back in again.
-
-
- There's an easy way and a hard way to do this. The easy way is to use
- the umlgdb expect script written by Chandan Kudige. It basically
- automates the process for you.
-
-
- First, you must tell it where your modules are. There is a list in
- the script that looks like this::
-
- set MODULE_PATHS {
- "fat" "/usr/src/uml/linux-2.4.18/fs/fat/fat.o"
- "isofs" "/usr/src/uml/linux-2.4.18/fs/isofs/isofs.o"
- "minix" "/usr/src/uml/linux-2.4.18/fs/minix/minix.o"
- }
-
-
-
-
- You change that to list the names and paths of the modules that you
- are going to debug. Then you run it from the toplevel directory of
- your UML pool and it basically tells you what to do::
-
-
- ******** GDB pid is 21903 ********
- Start UML as: ./linux <kernel switches> debug gdb-pid=21903

- (gdb) b sys_init_module
- Breakpoint 1 at 0xa0011923: file module.c, line 349.
- (gdb) att 1
-
-
-
-
- After you run UML and it sits there doing nothing, you hit return at
- the 'att 1' and continue it::
-
-
- Attaching to program: /home/jdike/linux/2.4/um/./linux, process 1
- 0xa00f4221 in __kill ()
- (UML gdb) c
- Continuing.
-
-
-
-
- At this point, you debug normally. When you insmod something, the
- expect magic will kick in and you'll see something like::
-
-

- kernel_data = 0xf689c35d <Address 0xf689c35d out of bounds>}
- >> Finished loading symbols for hostfs ...
-
-
-
-
- That's the easy way. It's highly recommended. The hard way is
- described below in case you're interested in what's going on.
-
-
- Boot the kernel under the debugger and load the module with insmod or
- modprobe. With gdb, do::
-
-
- (UML gdb) p module_list
-
-
-
-
- This is a list of modules that have been loaded into the kernel, with
- the most recently loaded module first. Normally, the module you want
- is at module_list. If it's not, walk down the next links, looking at
- the name fields until find the module you want to debug. Take the
- address of that structure, and add module.size_of_struct (which in
- 2.4.10 kernels is 96 (0x60)) to it. Gdb can make this hard addition
- for you :-)::
-
-
-
- (UML gdb)
- printf "%#x\n", (int)module_list module_list->size_of_struct
-
-
-
-
- The offset from the module start occasionally changes (before 2.4.0,
- it was module.size_of_struct + 4), so it's a good idea to check the
- init and cleanup addresses once in a while, as describe below. Now
- do::
-
-
- (UML gdb)
- add-symbol-file /path/to/module/on/host that_address
-
-
-
-
- Tell gdb you really want to do it, and you're in business.
-
-
- If there's any doubt that you got the offset right, like breakpoints
- appear not to work, or they're appearing in the wrong place, you can
- check it by looking at the module structure. The init and cleanup
- fields should look like::
-
-
- init = 0x588066b0 <init_hostfs>, cleanup = 0x588066c0 <exit_hostfs>
-
-
-
-
- with no offsets on the symbol names. If the names are right, but they
- are offset, then the offset tells you how much you need to add to the
- address you gave to add-symbol-file.
-
-
- When you want to load in a new version of the module, you need to get
- gdb to forget about the old one. The only way I've found to do that
- is to tell gdb to forget about all symbols that it knows about::
-
-
- (UML gdb) symbol-file
-
-
-
-
- Then reload the symbols from the kernel binary::
-
-
- (UML gdb) symbol-file /path/to/kernel
-
-
-
-
- and repeat the process above. You'll also need to re-enable break-
- points. They were disabled when you dumped all the symbols because
- gdb couldn't figure out where they should go.
-
-
-
-11.5. Attaching gdb to the kernel
-----------------------------------
-
- If you don't have the kernel running under gdb, you can attach gdb to
- it later by sending the tracing thread a SIGUSR1. The first line of
- the console output identifies its pid::
-
- tracing thread pid = 20093
-
-
-
-
- When you send it the signal::
-
-
- host% kill -USR1 20093
-
-
-
-
- you will get an xterm with gdb running in it.
-
-
- If you have the mconsole compiled into UML, then the mconsole client
- can be used to start gdb::
-
-
- (mconsole) (mconsole) config gdb=xterm
-
-
-
-
- will fire up an xterm with gdb running in it.
-
-
-
-11.6. Using alternate debuggers
---------------------------------
-
- UML has support for attaching to an already running debugger rather
- than starting gdb itself. This is present in CVS as of 17 Apr 2001.
- I sent it to Alan for inclusion in the ac tree, and it will be in my
- 2.4.4 release.
-
-
- This is useful when gdb is a subprocess of some UI, such as emacs or
- ddd. It can also be used to run debuggers other than gdb on UML.
- Below is an example of using strace as an alternate debugger.
-
-
- To do this, you need to get the pid of the debugger and pass it in
- with the
-
-
- If you are using gdb under some UI, then tell it to 'att 1', and
- you'll find yourself attached to UML.
-
-
- If you are using something other than gdb as your debugger, then
- you'll need to get it to do the equivalent of 'att 1' if it doesn't do
- it automatically.
-
-
- An example of an alternate debugger is strace. You can strace the
- actual kernel as follows:
-
- - Run the following in a shell::
-
-
- host%
- sh -c 'echo pid=$$; echo -n hit return; read x; exec strace -p 1 -o strace.out'
-
-
-
- - Run UML with 'debug' and 'gdb-pid=<pid>' with the pid printed out
- by the previous command
-
- - Hit return in the shell, and UML will start running, and strace
- output will start accumulating in the output file.
-
- Note that this is different from running::
-
-
- host% strace ./linux
-
-
-
-
- That will strace only the main UML thread, the tracing thread, which
- doesn't do any of the actual kernel work. It just oversees the vir-
- tual machine. In contrast, using strace as described above will show
- you the low-level activity of the virtual machine.
-

-12. Kernel debugging examples
-==============================
-
-12.1. The case of the hung fsck
---------------------------------
-
- When booting up the kernel, fsck failed, and dropped me into a shell
- to fix things up. I ran fsck -y, which hung::
-
-
- Setting hostname uml [ OK ]
- Checking root filesystem
- /dev/fhd0 was not cleanly unmounted, check forced.
- Error reading block 86894 (Attempt to read block from filesystem resulted in short read) while reading indirect blocks of inode 19780.
-
- /dev/fhd0: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
- (i.e., without -a or -p options)
- [ FAILED ]
-
- *** An error occurred during the file system check.
- *** Dropping you to a shell; the system will reboot
- *** when you leave the shell.
- Give root password for maintenance
- (or type Control-D for normal startup):
-
- [root@uml /root]# fsck -y /dev/fhd0
- fsck -y /dev/fhd0
- Parallelizing fsck version 1.14 (9-Jan-1999)
- e2fsck 1.14, 9-Jan-1999 for EXT2 FS 0.5b, 95/08/09
- /dev/fhd0 contains a file system with errors, check forced.
- Pass 1: Checking inodes, blocks, and sizes
- Error reading block 86894 (Attempt to read block from filesystem resulted in short read) while reading indirect blocks of inode 19780. Ignore error? yes
-
- Inode 19780, i_blocks is 1548, should be 540. Fix? yes
-
- Pass 2: Checking directory structure
- Error reading block 49405 (Attempt to read block from filesystem resulted in short read). Ignore error? yes
-
- Directory inode 11858, block 0, offset 0: directory corrupted
- Salvage? yes
-
- Missing '.' in directory inode 11858.
- Fix? yes
-
- Missing '..' in directory inode 11858.
- Fix? yes
-
-
- The standard drill in this sort of situation is to fire up gdb on the
- signal thread, which, in this case, was pid 1935. In another window,
- I run gdb and attach pid 1935::
-
-
- ~/linux/2.3.26/um 1016: gdb linux
- GNU gdb 4.17.0.11 with Linux support
- Copyright 1998 Free Software Foundation, Inc.

- welcome to change it and/or distribute copies of it under certain conditions.
- Type "show copying" to see the conditions.
- There is absolutely no warranty for GDB. Type "show warranty" for details.
- This GDB was configured as "i386-redhat-linux"...
-
- (gdb) att 1935
- Attaching to program `/home/dike/linux/2.3.26/um/linux', Pid 1935
- 0x100756d9 in __wait4 ()
-
-
- Let's see what's currently running::
-
-
-
- (gdb) p current_task.pid
- $1 = 0
-
-
-
-
-
- It's the idle thread, which means that fsck went to sleep for some
- reason and never woke up.
-
-
- Let's guess that the last process in the process list is fsck::
-
-
-
- (gdb) p current_task.prev_task.comm
- $13 = "fsck.ext2\000\000\000\000\000\000"
-
-
-
-
-
- It is, so let's see what it thinks it's up to::
-
-
-
- (gdb) p current_task.prev_task.thread
- $14 = {extern_pid = 1980, tracing = 0, want_tracing = 0, forking = 0,
- kernel_stack_page = 0, signal_stack = 1342627840, syscall = {id = 4, args = {
- 3, 134973440, 1024, 0, 1024}, have_result = 0, result = 50590720},
- request = {op = 2, u = {exec = {ip = 1350467584, sp = 2952789424}, fork = {
- regs = {1350467584, 2952789424, 0 <repeats 15 times>}, sigstack = 0,
- pid = 0}, switch_to = 0x507e8000, thread = {proc = 0x507e8000,
- arg = 0xaffffdb0, flags = 0, new_pid = 0}, input_request = {
- op = 1350467584, fd = -1342177872, proc = 0, pid = 0}}}}
-
-
-
- The interesting things here are the fact that its .thread.syscall.id
- is __NR_write (see the big switch in arch/um/kernel/syscall_kern.c or
- the defines in include/asm-um/arch/unistd.h), and that it never
- returned. Also, its .request.op is OP_SWITCH (see
- arch/um/include/user_util.h). These mean that it went into a write,
- and, for some reason, called schedule().
-
-
- The fact that it never returned from write means that its stack should
- be fairly interesting. Its pid is 1980 (.thread.extern_pid). That
- process is being ptraced by the signal thread, so it must be detached
- before gdb can attach it::
-
-
-
- (gdb) call detach(1980)
-
- Program received signal SIGSEGV, Segmentation fault.
- <function called from gdb>
- The program being debugged stopped while in a function called from GDB.
- When the function (detach) is done executing, GDB will silently
- stop (instead of continuing to evaluate the expression containing
- the function call).
- (gdb) call detach(1980)
- $15 = 0
-
-
- The first detach segfaults for some reason, and the second one
- succeeds.
-
-
- Now I detach from the signal thread, attach to the fsck thread, and
- look at its stack::
-
-
- (gdb) det

-
-
-
-
-
- The interesting things here are:
-
- - There are two segfaults on this stack (frames 9 and 14)
-
- - The first faulting address (frame 11) is 0x50000800::
-
- (gdb) p (void *)1342179328
- $16 = (void *) 0x50000800
-
-
-
-
-
- The initial faulting address is interesting because it is on the idle
- thread's stack. I had been seeing the idle thread segfault for no
- apparent reason, and the cause looked like stack corruption. In hopes
- of catching the culprit in the act, I had turned off all protections
- to that stack while the idle thread wasn't running. This apparently
- tripped that trap.
-
-
- However, the more immediate problem is that second segfault and I'm
- going to concentrate on that. First, I want to see where the fault
- happened, so I have to go look at the sigcontent struct in frame 8::
-
-
-
- (gdb) up

-
- Something is apparently wrong with the page tables or vma_structs, so
- lets go back to frame 11 and have a look at them::
-
-
-
- #11 0x1006c0aa in segv (address=1342179328, is_write=2) at trap_kern.c:50
- 50 handle_mm_fault(current, vma, address, is_write);
- (gdb) call pgd_offset_proc(vma->vm_mm, address)
- $22 = (pgd_t *) 0x80a548c
-
-
-
-
-
- That's pretty bogus. Page tables aren't supposed to be in process
- text or data areas. Let's see what's in the vma::
-
-
- (gdb) p *vma
- $23 = {vm_mm = 0x507d2434, vm_start = 0, vm_end = 134512640,
- vm_next = 0x80a4f8c, vm_page_prot = {pgprot = 0}, vm_flags = 31200,

- vm_private_data = 0x62}
- (gdb) p *vma.vm_mm
- $24 = {mmap = 0x507d2434, mmap_avl = 0x0, mmap_cache = 0x8048000,
- pgd = 0x80a4f8c, mm_users = {counter = 0}, mm_count = {counter = 134904288},
- map_count = 134909076, mmap_sem = {count = {counter = 135073792},
- sleepers = -1342177872, wait = {lock = <optimized out or zero length>,
- task_list = {next = 0xaffffe63, prev = 0xaffffe7a},
- __magic = -1342177670, __creator = -1342177300}, __magic = 98},
- page_table_lock = {}, context = 138, start_code = 0, end_code = 0,
- start_data = 0, end_data = 0, start_brk = 0, brk = 0, start_stack = 0,
- arg_start = 0, arg_end = 0, env_start = 0, env_end = 0, rss = 1350381536,
- total_vm = 0, locked_vm = 0, def_flags = 0, cpu_vm_mask = 0, swap_cnt = 0,
- swap_address = 0, segments = 0x0}
-
-
-
- This also pretty bogus. With all of the 0x80xxxxx and 0xaffffxxx
- addresses, this is looking like a stack was plonked down on top of
- these structures. Maybe it's a stack overflow from the next page::
-
-
- (gdb) p vma
- $25 = (struct vm_area_struct *) 0x507d2434
-
-
-
- That's towards the lower quarter of the page, so that would have to
- have been pretty heavy stack overflow::

-
-
- It's not stack overflow. The only "stack-like" piece of this data is
- the vma_struct itself.
-
-
- At this point, I don't see any avenues to pursue, so I just have to
- admit that I have no idea what's going on. What I will do, though, is
- stick a trap on the segfault handler which will stop if it sees any
- writes to the idle thread's stack. That was the thing that happened
- first, and it may be that if I can catch it immediately, what's going
- on will be somewhat clearer.

-12.2. Episode 2: The case of the hung fsck
--------------------------------------------
-
- After setting a trap in the SEGV handler for accesses to the signal
- thread's stack, I reran the kernel.
-
-
- fsck hung again, this time by hitting the trap::
-
-
-
- Setting hostname uml [ OK ]
- Checking root filesystem
- /dev/fhd0 contains a file system with errors, check forced.
- Error reading block 86894 (Attempt to read block from filesystem resulted in short read) while reading indirect blocks of inode 19780.
-
- /dev/fhd0: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
- (i.e., without -a or -p options)
- [ FAILED ]
-
- *** An error occurred during the file system check.
- *** Dropping you to a shell; the system will reboot
- *** when you leave the shell.
- Give root password for maintenance
- (or type Control-D for normal startup):
-
- [root@uml /root]# fsck -y /dev/fhd0
- fsck -y /dev/fhd0
- Parallelizing fsck version 1.14 (9-Jan-1999)
- e2fsck 1.14, 9-Jan-1999 for EXT2 FS 0.5b, 95/08/09
- /dev/fhd0 contains a file system with errors, check forced.
- Pass 1: Checking inodes, blocks, and sizes
- Error reading block 86894 (Attempt to read block from filesystem resulted in short read) while reading indirect blocks of inode 19780. Ignore error? yes
-
- Pass 2: Checking directory structure
- Error reading block 49405 (Attempt to read block from filesystem resulted in short read). Ignore error? yes
-
- Directory inode 11858, block 0, offset 0: directory corrupted
- Salvage? yes
-
- Missing '.' in directory inode 11858.
- Fix? yes
-
- Missing '..' in directory inode 11858.
- Fix? yes
-
- Untested (4127) [100fe44c]: trap_kern.c line 31
-
-
-
-
-
- I need to get the signal thread to detach from pid 4127 so that I can
- attach to it with gdb. This is done by sending it a SIGUSR1, which is
- caught by the signal thread, which detaches the process::
-
-
- kill -USR1 4127
-
-
-
-
-
- Now I can run gdb on it::

-
-
-
- Looking at the source shows that the fault happened during a call to
- copy_from_user to copy the data into the kernel::
-
-
- 107 count -= chars;
- 108 copy_from_user(p,buf,chars);
- 109 p += chars;
- 110 buf += chars;
-
-
-
- p is the pointer which must contain 0x50000800, since buf contains
- 0x80b8800 (frame 8 above). It is defined as::
-
-
- p = offset + bh->b_data;
-
-
-
-
-
- I need to figure out what bh is, and it just so happens that bh is
- passed as an argument to mark_buffer_uptodate and mark_buffer_dirty a
- few lines later, so I do a little disassembly::
-
-
- (gdb) disas 0x1001c2bf 0x1001c2e0

- End of assembler dump.
-
-
-
-
-
- At that point, bh is in %edx (address 0x1001c2da), which is calculated
- at 0x1001c2c2 as %ebp + 0xfffffdd4, so I figure exactly what that is,
- taking %ebp from the sigcontext_struct above::
-

- Now, I look at the structure to see what's in it, and particularly,
- what its b_data field contains::

-
- (gdb) p *((struct buffer_head *)0x50100200)

- The b_data field is indeed 0x50000800, so the question becomes how
- that happened. The rest of the structure looks fine, so this probably
- is not a case of data corruption. It happened on purpose somehow.
-
-
- The b_page field is a pointer to the page_struct representing the
- 0x50000000 page. Looking at it shows the kernel's idea of the state
- of that page::
-
-
-
- (gdb) p *$13.b_page
- $17 = {list = {next = 0x50004a5c, prev = 0x100c5174}, mapping = 0x0,
- index = 0, next_hash = 0x0, count = {counter = 1}, flags = 132, lru = {
- next = 0x50008460, prev = 0x50019350}, wait = {
- lock = <optimized out or zero length>, task_list = {next = 0x50004024,
- prev = 0x50004024}, __magic = 1342193708, __creator = 0},
- pprev_hash = 0x0, buffers = 0x501002c0, virtual = 1342177280,
- zone = 0x100c5160}
-
-
-
-
-
- Some sanity-checking: the virtual field shows the "virtual" address of
- this page, which in this kernel is the same as its "physical" address,
- and the page_struct itself should be mem_map[0], since it represents
- the first page of memory::
-
-
-
- (gdb) p (void *)1342177280
- $18 = (void *) 0x50000000
- (gdb) p mem_map
- $19 = (mem_map_t *) 0x50004000
-
-
-
-
-
- These check out fine.
-
-
- Now to check out the page_struct itself. In particular, the flags
- field shows whether the page is considered free or not::
-
-
- (gdb) p (void *)132
- $21 = (void *) 0x84
-
-
-
-
-
- The "reserved" bit is the high bit, which is definitely not set, so
- the kernel considers the signal stack page to be free and available to
- be used.
-
-
- At this point, I jump to conclusions and start looking at my early
- boot code, because that's where that page is supposed to be reserved.
-
-
- In my setup_arch procedure, I have the following code which looks just
- fine::
-
-
-
- bootmap_size = init_bootmem(start_pfn, end_pfn - start_pfn);
- free_bootmem(__pa(low_physmem) + bootmap_size, high_physmem - low_physmem);
-
-
-
-
-
- Two stack pages have already been allocated, and low_physmem points to
- the third page, which is the beginning of free memory.
- The init_bootmem call declares the entire memory to the boot memory
- manager, which marks it all reserved. The free_bootmem call frees up
- all of it, except for the first two pages. This looks correct to me.
-
-
- So, I decide to see init_bootmem run and make sure that it is marking
- those first two pages as reserved. I never get that far.
-
-
- Stepping into init_bootmem, and looking at bootmem_map before looking
- at what it contains shows the following::
-
-
-
- (gdb) p bootmem_map
- $3 = (void *) 0x50000000
-
-
-
-
-
- Aha! The light dawns. That first page is doing double duty as a
- stack and as the boot memory map. The last thing that the boot memory
- manager does is to free the pages used by its memory map, so this page
- is getting freed even its marked as reserved.
-
-
- The fix was to initialize the boot memory manager before allocating
- those two stack pages, and then allocate them through the boot memory
- manager. After doing this, and fixing a couple of subsequent buglets,
- the stack corruption problem disappeared.
-

-13. What to do when UML doesn't work
-=====================================
-
-
-
-
-13.1. Strange compilation errors when you build from source
-------------------------------------------------------------
-
- As of test11, it is necessary to have "ARCH=um" in the environment or
- on the make command line for all steps in building UML, including
- clean, distclean, or mrproper, config, menuconfig, or xconfig, dep,
- and linux. If you forget for any of them, the i386 build seems to
- contaminate the UML build. If this happens, start from scratch with::
-
-
- host%
- make mrproper ARCH=um
-
-
-
-
- and repeat the build process with ARCH=um on all the steps.
-
-
- See :ref:`Compiling_the_kernel_and_modules` for more details.
-
-
- Another cause of strange compilation errors is building UML in
- /usr/src/linux. If you do this, the first thing you need to do is
- clean up the mess you made. The /usr/src/linux/asm link will now
- point to /usr/src/linux/asm-um. Make it point back to
- /usr/src/linux/asm-i386. Then, move your UML pool someplace else and
- build it there. Also see below, where a more specific set of symptoms
- is described.
-
-
-
-13.3. A variety of panics and hangs with /tmp on a reiserfs filesystem
------------------------------------------------------------------------
-
- I saw this on reiserfs 3.5.21 and it seems to be fixed in 3.5.27.
- Panics preceded by::
-
-
- Detaching pid nnnn
-
-
-
- are diagnostic of this problem. This is a reiserfs bug which causes a
- thread to occasionally read stale data from a mmapped page shared with
- another thread. The fix is to upgrade the filesystem or to have /tmp
- be an ext2 filesystem.
-
-
-
- 13.4. The compile fails with errors about conflicting types for
- 'open', 'dup', and 'waitpid'
-
- This happens when you build in /usr/src/linux. The UML build makes
- the include/asm link point to include/asm-um. /usr/include/asm points
- to /usr/src/linux/include/asm, so when that link gets moved, files
- which need to include the asm-i386 versions of headers get the
- incompatible asm-um versions. The fix is to move the include/asm link
- back to include/asm-i386 and to do UML builds someplace else.
-
-
-
-13.5. UML doesn't work when /tmp is an NFS filesystem
-------------------------------------------------------
-
- This seems to be a similar situation with the ReiserFS problem above.
- Some versions of NFS seems not to handle mmap correctly, which UML
- depends on. The workaround is have /tmp be a non-NFS directory.
-
-
-13.6. UML hangs on boot when compiled with gprof support
----------------------------------------------------------
-
- If you build UML with gprof support and, early in the boot, it does
- this::
-
-
- kernel BUG at page_alloc.c:100!
-
-
-
-
- you have a buggy gcc. You can work around the problem by removing
- UM_FASTCALL from CFLAGS in arch/um/Makefile-i386. This will open up
- another bug, but that one is fairly hard to reproduce.
-
-
-
-13.7. syslogd dies with a SIGTERM on startup
----------------------------------------------
-
- The exact boot error depends on the distribution that you're booting,
- but Debian produces this::
-
-
- /etc/rc2.d/S10sysklogd: line 49: 93 Terminated
- start-stop-daemon --start --quiet --exec /sbin/syslogd -- $SYSLOGD
-
-
-
-
- This is a syslogd bug. There's a race between a parent process
- installing a signal handler and its child sending the signal.
-
-
-
-13.8. TUN/TAP networking doesn't work on a 2.4 host
-----------------------------------------------------
-
- There are a couple of problems which were reported by
- Tim Robinson <timro at trkr dot net>
-
- - It doesn't work on hosts running 2.4.7 (or thereabouts) or earlier.
- The fix is to upgrade to something more recent and then read the
- next item.
-
- - If you see::
-
-
- File descriptor in bad state
-
-
-
- when you bring up the device inside UML, you have a header mismatch
- between the original kernel and the upgraded one. Make /usr/src/linux
- point at the new headers. This will only be a problem if you build
- uml_net yourself.
-
-
-
-13.9. You can network to the host but not to other machines on the net
-=======================================================================
-
- If you can connect to the host, and the host can connect to UML, but
- you cannot connect to any other machines, then you may need to enable
- IP Masquerading on the host. Usually this is only experienced when
- using private IP addresses (192.168.x.x or 10.x.x.x) for host/UML
- networking, rather than the public address space that your host is
- connected to. UML does not enable IP Masquerading, so you will need
- to create a static rule to enable it::
-
-
- host%
- iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
-
-
-
-
- Replace eth0 with the interface that you use to talk to the rest of
- the world.
-
-
- Documentation on IP Masquerading, and SNAT, can be found at
- http://www.netfilter.org.
-
-
- If you can reach the local net, but not the outside Internet, then
- that is usually a routing problem. The UML needs a default route::
-
-
- UML#
- route add default gw gateway IP
-
-
-
-
- The gateway IP can be any machine on the local net that knows how to
- reach the outside world. Usually, this is the host or the local net-
- work's gateway.
-
-
- Occasionally, we hear from someone who can reach some machines, but
- not others on the same net, or who can reach some ports on other
- machines, but not others. These are usually caused by strange
- firewalling somewhere between the UML and the other box. You track
- this down by running tcpdump on every interface the packets travel
- over and see where they disappear. When you find a machine that takes
- the packets in, but does not send them onward, that's the culprit.
-
-
-
-13.10. I have no root and I want to scream
-===========================================
-
- Thanks to Birgit Wahlich for telling me about this strange one. It
- turns out that there's a limit of six environment variables on the
- kernel command line. When that limit is reached or exceeded, argument
- processing stops, which means that the 'root=' argument that UML
- usually adds is not seen. So, the filesystem has no idea what the
- root device is, so it panics.
-
-
- The fix is to put less stuff on the command line. Glomming all your
- setup variables into one is probably the best way to go.
-
-
-
-13.11. UML build conflict between ptrace.h and ucontext.h
-==========================================================
-
- On some older systems, /usr/include/asm/ptrace.h and
- /usr/include/sys/ucontext.h define the same names. So, when they're
- included together, the defines from one completely mess up the parsing
- of the other, producing errors like::
-
- /usr/include/sys/ucontext.h:47: parse error before
- `10`
-
-
-
-
- plus a pile of warnings.
-
-
- This is a libc botch, which has since been fixed, and I don't see any
- way around it besides upgrading.
-
-
-
-13.12. The UML BogoMips is exactly half the host's BogoMips
-------------------------------------------------------------
-
- On i386 kernels, there are two ways of running the loop that is used
- to calculate the BogoMips rating, using the TSC if it's there or using
- a one-instruction loop. The TSC produces twice the BogoMips as the
- loop. UML uses the loop, since it has nothing resembling a TSC, and
- will get almost exactly the same BogoMips as a host using the loop.
- However, on a host with a TSC, its BogoMips will be double the loop
- BogoMips, and therefore double the UML BogoMips.
-
-
-
-13.13. When you run UML, it immediately segfaults
---------------------------------------------------
-
- If the host is configured with the 2G/2G address space split, that's
- why. See ref:`UML_on_2G/2G_hosts` for the details on getting UML to
- run on your host.
-
-
-
-13.14. xterms appear, then immediately disappear
--------------------------------------------------
-
- If you're running an up to date kernel with an old release of
- uml_utilities, the port-helper program will not work properly, so
- xterms will exit straight after they appear. The solution is to
- upgrade to the latest release of uml_utilities. Usually this problem
- occurs when you have installed a packaged release of UML then compiled
- your own development kernel without upgrading the uml_utilities from
- the source distribution.
-
-
-
-13.15. Any other panic, hang, or strange behavior
---------------------------------------------------
-
- If you're seeing truly strange behavior, such as hangs or panics that
- happen in random places, or you try running the debugger to see what's
- happening and it acts strangely, then it could be a problem in the
- host kernel. If you're not running a stock Linus or -ac kernel, then
- try that. An early version of the preemption patch and a 2.4.10 SuSE
- kernel have caused very strange problems in UML.
-
-
- Otherwise, let me know about it. Send a message to one of the UML
- mailing lists - either the developer list - user-mode-linux-devel at
- lists dot sourceforge dot net (subscription info) or the user list -
- user-mode-linux-user at lists dot sourceforge do net (subscription
- info), whichever you prefer. Don't assume that everyone knows about
- it and that a fix is imminent.
-
-
- If you want to be super-helpful, read :ref:`Diagnosing_Problems` and
- follow the instructions contained therein.
-
-.. _Diagnosing_Problems:
-
-14. Diagnosing Problems
-========================
-
-
- If you get UML to crash, hang, or otherwise misbehave, you should
- report this on one of the project mailing lists, either the developer
- list - user-mode-linux-devel at lists dot sourceforge dot net
- (subscription info) or the user list - user-mode-linux-user at lists
- dot sourceforge dot net (subscription info). When you do, it is
- likely that I will want more information. So, it would be helpful to
- read the stuff below, do whatever is applicable in your case, and
- report the results to the list.
-
-
- For any diagnosis, you're going to need to build a debugging kernel.
- The binaries from this site aren't debuggable. If you haven't done
- this before, read about :ref:`Compiling_the_kernel_and_modules` and
- :ref:`Kernel_debugging` UML first.
-
-
-14.1. Case 1 : Normal kernel panics
-------------------------------------
-
- The most common case is for a normal thread to panic. To debug this,
- you will need to run it under the debugger (add 'debug' to the command
- line). An xterm will start up with gdb running inside it. Continue
- it when it stops in start_kernel and make it crash. Now ``^C gdb`` and
-
-
- If the panic was a "Kernel mode fault", then there will be a segv
- frame on the stack and I'm going to want some more information. The
- stack might look something like this::
-
-
- (UML gdb) backtrace
- #0 0x1009bf76 in __sigprocmask (how=1, set=0x5f347940, oset=0x0)
- at ../sysdeps/unix/sysv/linux/sigprocmask.c:49
- #1 0x10091411 in change_sig (signal=10, on=1) at process.c:218
- #2 0x10094785 in timer_handler (sig=26) at time_kern.c:32
- #3 0x1009bf38 in __restore ()
- at ../sysdeps/unix/sysv/linux/i386/sigaction.c:125
- #4 0x1009534c in segv (address=8, ip=268849158, is_write=2, is_user=0)
- at trap_kern.c:66
- #5 0x10095c04 in segv_handler (sig=11) at trap_user.c:285
- #6 0x1009bf38 in __restore ()
-
-
-
-
- I'm going to want to see the symbol and line information for the value
- of ip in the segv frame. In this case, you would do the following::
-
-
- (UML gdb) i sym 268849158
-
-
-
-
- and::
-
-
- (UML gdb) i line *268849158
-
-
-
-
- The reason for this is the __restore frame right above the segv_han-
- dler frame is hiding the frame that actually segfaulted. So, I have
- to get that information from the faulting ip.
-
-
-14.2. Case 2 : Tracing thread panics
--------------------------------------
-
- The less common and more painful case is when the tracing thread
- panics. In this case, the kernel debugger will be useless because it
- needs a healthy tracing thread in order to work. The first thing to
- do is get a backtrace from the tracing thread. This is done by
- figuring out what its pid is, firing up gdb, and attaching it to that
- pid. You can figure out the tracing thread pid by looking at the
- first line of the console output, which will look like this::
-
-
- tracing thread pid = 15851
-
-
-
-
- or by running ps on the host and finding the line that looks like
- this::
-
-
- jdike 15851 4.5 0.4 132568 1104 pts/0 S 21:34 0:05 ./linux [(tracing thread)]
-
-
-
-
- If the panic was 'segfault in signals', then follow the instructions
- above for collecting information about the location of the seg fault.
-
-
- If the tracing thread flaked out all by itself, then send that
- backtrace in and wait for our crack debugging team to fix the problem.
-
-
- 14.3. Case 3 : Tracing thread panics caused by other threads
-
- However, there are cases where the misbehavior of another thread
- caused the problem. The most common panic of this type is::
-
-
- wait_for_stop failed to wait for <pid> to stop with <signal number>
-
-
-
-
- In this case, you'll need to get a backtrace from the process men-
- tioned in the panic, which is complicated by the fact that the kernel
- debugger is defunct and without some fancy footwork, another gdb can't
- attach to it. So, this is how the fancy footwork goes:
-
- In a shell::
-
-
- host% kill -STOP pid
-
-
-
-
- Run gdb on the tracing thread as described in case 2 and do::
-
-
- (host gdb) call detach(pid)
-
-
- If you get a segfault, do it again. It always works the second time.
-
- Detach from the tracing thread and attach to that other thread::
-
-
- (host gdb) detach
-
-
-
-
-
-
- (host gdb) attach pid
-
-
-
-
- If gdb hangs when attaching to that process, go back to a shell and
- do::
-
-
- host%
- kill -CONT pid
-
-
-
-
- And then get the backtrace::
-
-
- (host gdb) backtrace
-
-
-
-
-
-14.4. Case 4 : Hangs
----------------------
-
- Hangs seem to be fairly rare, but they sometimes happen. When a hang
- happens, we need a backtrace from the offending process. Run the
- kernel debugger as described in case 1 and get a backtrace. If the
- current process is not the idle thread, then send in the backtrace.
- You can tell that it's the idle thread if the stack looks like this::
-
-
- #0 0x100b1401 in __libc_nanosleep ()
- #1 0x100a2885 in idle_sleep (secs=10) at time.c:122
- #2 0x100a546f in do_idle () at process_kern.c:445
- #3 0x100a5508 in cpu_idle () at process_kern.c:471
- #4 0x100ec18f in start_kernel () at init/main.c:592
- #5 0x100a3e10 in start_kernel_proc (unused=0x0) at um_arch.c:71
- #6 0x100a383f in signal_tramp (arg=0x100a3dd8) at trap_user.c:50
-
-
-
-
- If this is the case, then some other process is at fault, and went to
- sleep when it shouldn't have. Run ps on the host and figure out which
- process should not have gone to sleep and stayed asleep. Then attach
- to it with gdb and get a backtrace as described in case 3.

+Introduction
+************
+
+Welcome to User Mode Linux
+
+User Mode Linux is the first Open Source virtualization platform (first
+release date 1991) and second virtualization platform for an x86 PC.
+
+How is UML Different from a VM using Virtualization package X?
+==============================================================
+
+We have come to assume that virtualization also means some level of
+hardware emulation. In fact, it does not. As long as a virtualization
+package provides the OS with devices which the OS can recognize and
+has a driver for, the devices do not need to emulate real hardware.
+Most OSes today have built-in support for a number of "fake"
+devices used only under virtualization.
+User Mode Linux takes this concept to the ultimate extreme - there
+is not a single real device in sight. It is 100% artificial or if
+we use the correct term 100% paravirtual. All UML devices are abstract
+concepts which map onto something provided by the host - files, sockets,
+pipes, etc.
+
+The other major difference between UML and various virtualization
+packages is that there is a distinct difference between the way the UML
+kernel and the UML programs operate.
+The UML kernel is just a process running on Linux - same as any other
+program. It can be run by an unprivileged user and it does not require
+anything in terms of special CPU features.
+The UML userspace, however, is a bit different. The Linux kernel on the
+host machine assists UML in intercepting everything the program running
+on a UML instance is trying to do and making the UML kernel handle all
+of its requests.
+This is different from other virtualization packages which do not make any
+difference between the guest kernel and guest programs. This difference
+results in a number of advantages and disadvantages of UML over let's say
+QEMU which we will cover later in this document.
+
+
+Why Would I Want User Mode Linux?
+=================================
+
+
+* If User Mode Linux kernel crashes, your host kernel is still fine. It
+ is not accelerated in any way (vhost, kvm, etc) and it is not trying to
+ access any devices directly. It is, in fact, a process like any other.
+
+* You can run a usermode kernel as a non-root user (you may need to
+ arrange appropriate permissions for some devices).
+
+* You can run a very small VM with a minimal footprint for a specific
+ task (for example 32M or less).
+
+* You can get extremely high performance for anything which is a "kernel
+ specific task" such as forwarding, firewalling, etc while still being
+ isolated from the host kernel.
+
+* You can play with kernel concepts without breaking things.
+
+* You are not bound by "emulating" hardware, so you can try weird and
+ wonderful concepts which are very difficult to support when emulating
+ real hardware such as time travel and making your system clock
+ dependent on what UML does (very useful for things like tests).
+
+* It's fun.
+
+Why not to run UML
+==================
+
+* The syscall interception technique used by UML makes it inherently
+ slower for any userspace applications. While it can do kernel tasks
+ on par with most other virtualization packages, its userspace is
+ **slow**. The root cause is that UML has a very high cost of creating
+ new processes and threads (something most Unix/Linux applications
+ take for granted).
+
+* UML is strictly uniprocessor at present. If you want to run an
+ application which needs many CPUs to function, it is clearly the
+ wrong choice.
+
+***********************
+Building a UML instance
+***********************
+
+There is no UML installer in any distribution. While you can use off
+the shelf install media to install into a blank VM using a virtualization
+package, there is no UML equivalent. You have to use appropriate tools on
+your host to build a viable filesystem image.
+
+This is extremely easy on Debian - you can do it using debootstrap. It is
+also easy on OpenWRT - the build process can build UML images. All other
+distros - YMMV.
+
+Creating an image
+=================
+
+Create a sparse raw disk image::
+
+ # dd if=/dev/zero of=disk_image_name bs=1 count=1 seek=16G
+
+This will create a 16G disk image. The OS will initially allocate only one
+block and will allocate more as they are written by UML. As of kernel
+version 4.19 UML fully supports TRIM (as usually used by flash drives).
+Using TRIM inside the UML image by specifying discard as a mount option
+or by running ``tune2fs -o discard /dev/ubdXX`` will request UML to
+return any unused blocks to the OS.
+
+Create a filesystem on the disk image and mount it::
+
+ # mkfs.ext4 ./disk_image_name && mount ./disk_image_name /mnt
+
+This example uses ext4, any other filesystem such as ext3, btrfs, xfs,
+jfs, etc will work too.
+
+Create a minimal OS installation on the mounted filesystem::
+
+ # debootstrap buster /mnt http://deb.debian.org/debian
+
+debootstrap does not set up the root password, fstab, hostname or
+anything related to networking. It is up to the user to do that.
+
+Set the root password -t he easiest way to do that is to chroot into the
+mounted image::
+
+ # chroot /mnt
+ # passwd
+ # exit
+
+Edit key system files
+=====================
+
+UML block devices are called ubds. The fstab created by debootstrap
+will be empty and it needs an entry for the root file system::
+
+ /dev/ubd0 ext4 discard,errors=remount-ro 0 1
+
+The image hostname will be set to the same as the host on which you
+are creating it image. It is a good idea to change that to avoid
+"Oh, bummer, I rebooted the wrong machine".
+
+UML supports two classes of network devices - the older uml_net ones
+which are scheduled for obsoletion. These are called ethX. It also
+supports the newer vector IO devices which are significantly faster
+and have support for some standard virtual network encapsulations like
+Ethernet over GRE and Ethernet over L2TPv3. These are called vec0.
+
+Depending on which one is in use, ``/etc/network/interfaces`` will
+need entries like::
+
+ # legacy UML network devices
+ auto eth0
+ iface eth0 inet dhcp
+
+ # vector UML network devices
+ auto vec0
+ iface eth0 inet dhcp
+
+We now have a UML image which is nearly ready to run, all we need is a
+UML kernel and modules for it.
+
+Most distributions have a UML package. Even if you intend to use your own
+kernel, testing the image with a stock one is always a good start. These
+packages come with a set of modules which should be copied to the target
+filesystem. The location is distribution dependent. For Debian these
+reside under /usr/lib/uml/modules. Copy recursively the content of this
+directory to the mounted UML filesystem::
+
+ # cp -rax /usr/lib/uml/modules /mnt/lib/modules
+
+If you have compiled your own kernel, you need to use the usual "install
+modules to a location" procedure by running::
+
+ # make install MODULES_DIR=/mnt/lib/modules
+
+At this point the image is ready to be brought up.
+
+*************************
+Setting Up UML Networking
+*************************
+
+UML networking is designed to emulate an Ethernet connection. This
+connection may be either a point-to-point (similar to a connection
+between machines using a back-to-back cable) or a connection to a
+switch. UML supports a wide variety of means to build these
+connections to all of: local machine, remote machine(s), local and
+remote UML and other VM instances.
+
+

+
+* All transports which have tso and checksum offloads can deliver speeds
+ approaching 10G on TCP streams.
+
+* All transports which have multi-packet rx and/or tx can deliver pps
+ rates of up to 1Mps or more.
+
+* All legacy transports are generally limited to ~600-700MBit and 0.05Mps
+
+* GRE and L2TPv3 allow connections to all of: local machine, remote
+ machines, remote network devices and remote UML instances.
+
+* Socket allows connections only between UML instances.
+
+* Daemon and bess require running a local switch. This switch may be
+ connected to the host as well.
+
+
+Network configuration privileges
+================================
+
+The majority of the supported networking modes need ``root`` privileges.
+For example, in the legacy tuntap networking mode, users were required
+to be part of the group associated with the tunnel device.
+
+For newer network drivers like the vector transports, ``root`` privilege
+is required to fire an ioctl to setup the tun interface and/or use
+raw sockets where needed.
+
+This can be achieved by granting the user a particular capability instead
+of running UML as root. In case of vector transport, a user can add the
+capability ``CAP_NET_ADMIN`` or ``CAP_NET_RAW``, to the uml binary.
+Thenceforth, UML can be run with normal user privilges, along with
+full networking.
+
+For example::
+
+ # sudo setcap cap_net_raw,cap_net_admin+ep linux
+
+Configuring vector transports
+===============================
+
+All vector transports support a similar syntax:
+
+If X is the interface number as in vec0, vec1, vec2, etc, the general
+syntax for options is::
+
+ vecX:transport="Transport Name",option=value,option=value,...,option=value
+
+Common options
+--------------
+
+These options are common for all transports:
+
+* ``depth=int`` - sets the queue depth for vector IO. This is the
+ amount of packets UML will attempt to read or write in a single
+ system call. The default number is 64 and is generally sufficient
+ for most applications that need throughput in the 2-4 Gbit range.
+ Higher speeds may require larger values.
+
+* ``mac=XX:XX:XX:XX:XX`` - sets the interface MAC address value.
+
+* ``gro=[0,1]`` - sets GRO on or off. Enables receive/transmit offloads.
+ The effect of this option depends on the host side support in the transport
+ which is being configured. In most cases it will enable TCP segmentation and
+ RX/TX checksumming offloads. The setting must be identical on the host side
+ and the UML side. The UML kernel will produce warnings if it is not.
+ For example, GRO is enabled by default on local machine interfaces
+ (e.g. veth pairs, bridge, etc), so it should be enabled in UML in the
+ corresponding UML transports (raw, tap, hybrid) in order for networking to
+ operate correctly.
+
+* ``mtu=int`` - sets the interface MTU
+
+* ``headroom=int`` - adjusts the default headroom (32 bytes) reserved
+ if a packet will need to be re-encapsulated into for instance VXLAN.
+
+* ``vec=0`` - disable multipacket io and fall back to packet at a
+ time mode
+
+Shared Options
+--------------
+
+* ``ifname=str`` Transports which bind to a local network interface
+ have a shared option - the name of the interface to bind to.
+
+* ``src, dst, src_port, dst_port`` - all transports which use sockets
+ which have the notion of source and destination and/or source port
+ and destination port use these to specify them.
+
+* ``v6=[0,1]`` to specify if a v6 connection is desired for all
+ transports which operate over IP. Additionally, for transports that
+ have some differences in the way they operate over v4 and v6 (for example
+ EoL2TPv3), sets the correct mode of operation. In the absense of this
+ option, the socket type is determined based on what do the src and dst
+ arguments resolve/parse to.
+
+tap transport
+-------------
+
+Example::
+
+ vecX:transport=tap,ifname=tap0,depth=128,gro=1
+
+This will connect vec0 to tap0 on the host. Tap0 must already exist (for example
+created using tunctl) and UP.
+
+tap0 can be configured as a point-to-point interface and given an ip
+address so that UML can talk to the host. Alternatively, it is possible
+to connect UML to a tap interface which is connected to a bridge.
+
+While tap relies on the vector infrastructure, it is not a true vector
+transport at this point, because Linux does not support multi-packet
+IO on tap file descriptors for normal userspace apps like UML. This
+is a privilege which is offered only to something which can hook up
+to it at kernel level via specialized interfaces like vhost-net. A
+vhost-net like helper for UML is planned at some point in the future.
+
+Privileges required: tap transport requires either:
+
+* tap interface to exist and be created persistent and owned by the
+ UML user using tunctl. Example ``tunctl -u uml-user -t tap0``
+
+* binary to have ``CAP_NET_ADMIN`` privilege
+
+hybrid transport
+----------------
+
+Example::
+
+ vecX:transport=hybrid,ifname=tap0,depth=128,gro=1
+
+This is an experimental/demo transport which couples tap for transmit
+and a raw socket for receive. The raw socket allows multi-packet
+receive resulting in significantly higher packet rates than normal tap
+
+Privileges required: hybrid requires ``CAP_NET_RAW`` capability by
+the UML user as well as the requirements for the tap transport.
+
+raw socket transport
+--------------------
+
+Example::
+
+ vecX:transport=raw,ifname=p-veth0,depth=128,gro=1
+
+
+This transport uses vector IO on raw sockets. While you can bind to any
+interface including a physical one, the most common use it to bind to
+the "peer" side of a veth pair with the other side configured on the
+host.
+
+Example host configuration for Debian:
+
+**/etc/network/interfaces**::
+
+ auto veth0
+ iface veth0 inet static
+ address 192.168.4.1
+ netmask 255.255.255.252
+ broadcast 192.168.4.3
+ pre-up ip link add veth0 type veth peer name p-veth0 && \
+ ifconfig p-veth0 up
+
+UML can now bind to p-veth0 like this::
+
+ vec0:transport=raw,ifname=p-veth0,depth=128,gro=1
+
+
+If the UML guest is configured with 192.168.4.2 and netmask 255.255.255.0
+it can talk to the host on 192.168.4.1
+
+The raw transport also provides some support for offloading some of the
+filtering to the host. The two options to control it are:
+
+* ``bpffile=str`` filename of raw bpf code to be loaded as a socket filter
+
+* ``bpfflash=int`` 0/1 allow loading of bpf from inside User Mode Linux.
+ This option allows the use of the ethtool load firmware command to
+ load bpf code.
+
+In either case the bpf code is loaded into the host kernel. While this is
+presently limited to legacy bpf syntax (not ebpf), it is still a security
+risk. It is not recommended to allow this unless the User Mode Linux
+instance is considered trusted.
+
+Privileges required: raw socket transport requires `CAP_NET_RAW`
+capability.
+
+GRE socket transport
+--------------------
+
+Example::
+
+ vecX:transport=gre,src=$src_host,dst=$dst_host
+
+
+This will configure an Ethernet over ``GRE`` (aka ``GRETAP`` or
+``GREIRB``) tunnel which will connect the UML instance to a ``GRE``
+endpoint at host dst_host. ``GRE`` supports the following additional
+options:
+
+* ``rx_key=int`` - GRE 32 bit integer key for rx packets, if set,
+ ``txkey`` must be set too
+
+* ``tx_key=int`` - GRE 32 bit integer key for tx packets, if set
+ ``rx_key`` must be set too
+
+* ``sequence=[0,1]`` - enable GRE sequence
+
+* ``pin_sequence=[0,1]`` - pretend that the sequence is always reset
+ on each packet (needed to interoperate with some really broken
+ implementations)
+
+* ``v6=[0,1]`` - force IPv4 or IPv6 sockets respectively
+
+* GRE checksum is not presently supported
+
+GRE has a number of caveats:
+
+* You can use only one GRE connection per ip address. There is no way to
+ multiplex connections as each GRE tunnel is terminated directly on
+ the UML instance.
+
+* The key is not really a security feature. While it was intended as such
+ it's "security" is laughable. It is, however, a useful feature to
+ ensure that the tunnel is not misconfigured.
+
+An example configuration for a Linux host with a local address of
+192.168.128.1 to connect to a UML instance at 192.168.129.1
+
+**/etc/network/interfaces**::
+
+ auto gt0
+ iface gt0 inet static
+ address 10.0.0.1
+ netmask 255.255.255.0
+ broadcast 10.0.0.255
+ mtu 1500
+ pre-up ip link add gt0 type gretap local 192.168.128.1 \
+ remote 192.168.129.1 || true
+ down ip link del gt0 || true
+
+Additionally, GRE has been tested versus a variety of network equipment.
+
+Privileges required: GRE requires ``CAP_NET_RAW``
+
+l2tpv3 socket transport
+-----------------------
+
+_Warning_. L2TPv3 has a "bug". It is the "bug" known as "has more
+options than GNU ls". While it has some advantages, there are usually
+easier (and less verbose) ways to connect a UML instance to something.
+For example, most devices which support L2TPv3 also support GRE.
+
+Example::
+
+ vec0:transport=l2tpv3,udp=1,src=$src_host,dst=$dst_host,srcport=$src_port,dstport=$dst_port,depth=128,rx_session=0xffffffff,tx_session=0xffff
+
+This will configure an Ethernet over L2TPv3 fixed tunnel which will
+connect the UML instance to a L2TPv3 endpoint at host $dst_host using
+the L2TPv3 UDP flavour and UDP destination port $dst_port.
+
+L2TPv3 always requires the following additional options:
+
+* ``rx_session=int`` - l2tpv3 32 bit integer session for rx packets
+
+* ``tx_session=int`` - l2tpv3 32 bit integer session for tx packets
+
+As the tunnel is fixed these are not negotiated and they are
+preconfigured on both ends.
+
+Additionally, L2TPv3 supports the following optional parameters
+
+* ``rx_cookie=int`` - l2tpv3 32 bit integer cookie for rx packets - same
+ functionality as GRE key, more to prevent misconfiguration than provide
+ actual security
+
+* ``tx_cookie=int`` - l2tpv3 32 bit integer cookie for tx packets
+
+* ``cookie64=[0,1]`` - use 64 bit cookies instead of 32 bit.
+
+* ``counter=[0,1]`` - enable l2tpv3 counter
+
+* ``pin_counter=[0,1]`` - pretend that the counter is always reset on
+ each packet (needed to interoperate with some really broken
+ implementations)
+
+* ``v6=[0,1]`` - force v6 sockets
+
+* ``udp=[0,1]`` - use raw sockets (0) or UDP (1) version of the protocol
+
+L2TPv3 has a number of caveats:
+
+* you can use only one connection per ip address in raw mode. There is
+ no way to multiplex connections as each L2TPv3 tunnel is terminated
+ directly on the UML instance. UDP mode can use different ports for
+ this purpose.
+
+Here is an example of how to configure a linux host to connect to UML
+via L2TPv3:
+
+**/etc/network/interfaces**::
+
+ auto l2tp1
+ iface l2tp1 inet static
+ address 192.168.126.1
+ netmask 255.255.255.0
+ broadcast 192.168.126.255
+ mtu 1500
+ pre-up ip l2tp add tunnel remote 127.0.0.1 \
+ local 127.0.0.1 encap udp tunnel_id 2 \
+ peer_tunnel_id 2 udp_sport 1706 udp_dport 1707 && \
+ ip l2tp add session name l2tp1 tunnel_id 2 \
+ session_id 0xffffffff peer_session_id 0xffffffff
+ down ip l2tp del session tunnel_id 2 session_id 0xffffffff && \
+ ip l2tp del tunnel tunnel_id 2
+
+
+Privileges required: L2TPv3 requires ``CAP_NET_RAW`` for raw IP mode and
+no special privileges for the UDP mode.
+
+BESS socket transport
+---------------------
+
+BESS is a high performance modular network switch.
+
+https://github.com/NetSys/bess
+
+It has support for a simple sequential packet socket mode which in the
+more recent versions is using vector IO for high performance.
+
+Example::
+
+ vecX:transport=bess,src=$unix_src,dst=$unix_dst
+
+This will configure a BESS transport using the unix_src Unix domain
+socket address as source and unix_dst socket address as destination.
+
+For BESS configuration and how to allocate a BESS Unix domain socket port
+please see the BESS documentation.
+
+https://github.com/NetSys/bess/wiki/Built-In-Modules-and-Ports
+
+BESS transport does not require any special privileges.
+
+Configuring Legacy transports
+=============================
+
+Legacy transports are now considered obsolete. Please use the vector
+versions.
+
+***********
+Running UML
+***********
+
+This section assumes that either the user-mode-linux package from the
+distribution or a custom built kernel has been installed on the host.
+
+These add an executable called linux to the system. This is the UML
+kernel. It can be run just like any other executable.
+It will take most normal linux kernel arguments as command line
+arguments. Additionally, it will need some UML specific arguments
+in order to do something useful.
+
+Arguments
+=========
+
+Mandatory Arguments:
+--------------------
+
+* ``mem=int[K,M,G]`` - amount of memory. By default bytes. It will
+ also accept K, M or G qualifiers.
+
+* ``ubdX[s,d,c,t]=`` virtual disk specification. This is not really
+ mandatory, but it is likely to be needed in nearly all cases so we can
+ specify a root file system.
+ The simplest possible image specification is the name of the image
+ file for the filesystem (created using one of the methods described
+ in `Creating an image`_)
+
+ * UBD devices support copy on write (COW). The changes are kept in
+ a separate file which can be discarded allowing a rollback to the
+ original pristine image. If COW is desired, the UBD image is
+ specified as: ``cow_file,master_image``.
+ Example:``ubd0=Filesystem.cow,Filesystem.img``
+
+ * UBD devices can be set to use synchronous IO. Any writes are
+ immediately flushed to disk. This is done by adding ``s`` after
+ the ``ubdX`` specification
+
+ * UBD performs some euristics on devices specified as a single
+ filename to make sure that a COW file has not been specified as
+ the image. To turn them off, use the ``d`` flag after ``ubdX``
+
+ * UBD supports TRIM - asking the Host OS to reclaim any unused
+ blocks in the image. To turn it off, specify the ``t`` flag after
+ ``ubdX``
+
+* ``root=`` root device - most likely ``/dev/ubd0`` (this is a Linux
+ filesystem image)
+
+Important Optional Arguments
+----------------------------
+
+If UML is run as "linux" with no extra arguments, it will try to start an
+xterm for every console configured inside the image (up to 6 in most
+linux distributions). Each console is started inside an
+xterm. This makes it nice and easy to use UML on a host with a GUI. It is,
+however, the wrong approach if UML is to be used as a testing harness or run
+in a text-only environment.
+
+In order to change this behaviour we need to specify an alternative console
+and wire it to one of the supported "line" channels. For this we need to map a
+console to use something different from the default xterm.
+
+Example which will divert console number 1 to stdin/stdout::
+
+ con1=fd:0,fd:1
+
+UML supports a wide variety of serial line channels which are specified using
+the following syntax
+
+ conX=channel_type:options[,channel_type:options]
+
+
+If the channel specification contains two parts separated by comma, the first
+one is input, the second one output.
+
+* The null channel - Discard all input or output. Example ``con=null`` will set
+ all consoles to null by default.
+
+* The fd channel - use file descriptor numbers for input/out. Example:
+ ``con1=fd:0,fd:1.``
+
+* The port channel - listen on tcp port number. Example: ``con1=port:4321``
+
+* The pty and pts channels - use system pty/pts.
+
+* The tty channel - bind to an existing system tty. Example: ``con1=/dev/tty8``
+ will make UML use the host 8th console (usually unused).
+
+* The xterm channel - this is the default - bring up an xterm on this channel
+ and direct IO to it. Note, that in order for xterm to work, the host must
+ have the UML distribution package installed. This usually contains the
+ port-helper and other utilities needed for UML to communicate with the xterm.
+ Alternatively, these need to be complied and installed from source. All
+ options applicable to consoles also apply to UML serial lines which are
+ presented as ttyS inside UML.
+
+Starting UML
+============
+
+We can now run UML.
+::
+
+ # linux mem=2048M umid=TEST \
+ ubd0=Filesystem.img \
+ vec0:transport=tap,ifname=tap0,depth=128,gro=1 \
+ root=/dev/ubda con=null con0=null,fd:2 con1=fd:0,fd:1
+
+This will run an instance with ``2048M RAM``, try to use the image file
+called ``Filesystem.img`` as root. It will connect to the host using tap0.
+All consoles except ``con1`` will be disabled and console 1 will
+use standard input/output making it appear in the same terminal it was started.
+
+Logging in
+============
+
+If you have not set up a password when generating the image, you will have to
+shut down the UML instance, mount the image, chroot into it and set it - as
+described in the Generating an Image section. If the password is already set,
+you can just log in.
+
+The UML Management Console
+============================
+
+In addition to managing the image from "the inside" using normal sysadmin tools,
+it is possible to perform a number of low level operations using the UML
+management console. The UML management console is a low-level interface to the
+kernel on a running UML instance, somewhat like the i386 SysRq interface. Since
+there is a full-blown operating system under UML, there is much greater
+flexibility possible than with the SysRq mechanism.
+
+There are a number of things you can do with the mconsole interface:
+
+* get the kernel version
+* add and remove devices
+* halt or reboot the machine
+* Send SysRq commands
+* Pause and resume the UML
+* Inspect processes running inside UML
+* Inspect UML internal /proc state
+
+You need the mconsole client (uml\_mconsole) which is a part of the UML
+tools package available in most Linux distritions.
+
+You also need ``CONFIG_MCONSOLE`` (under 'General Setup') enabled in the UML
+kernel. When you boot UML, you'll see a line like::
+
+ mconsole initialized on /home/jdike/.uml/umlNJ32yL/mconsole
+
+If you specify a unique machine id one the UML command line, i.e.
+``umid=debian``, you'll see this::
+
+ mconsole initialized on /home/jdike/.uml/debian/mconsole
+
+
+That file is the socket that uml_mconsole will use to communicate with
+UML. Run it with either the umid or the full path as its argument::
+
+ # uml_mconsole debian
+
+or
+
+ # uml_mconsole /home/jdike/.uml/debian/mconsole
+
+
+You'll get a prompt, at which you can run one of these commands:
+
+* version
+* help
+* halt
+* reboot
+* config
+* remove
+* sysrq
+* help
+* cad
+* stop
+* go
+* proc
+* stack
+
+version
+-------
+
+This command takes no arguments. It prints the UML version::
+
+ (mconsole) version
+ OK Linux OpenWrt 4.14.106 #0 Tue Mar 19 08:19:41 2019 x86_64
+
+
+There are a couple actual uses for this. It's a simple no-op which
+can be used to check that a UML is running. It's also a way of
+sending a device interrupt to the UML. UML mconsole is treated internally as
+a UML device.
+
+help
+----
+
+This command takes no arguments. It prints a short help screen with the
+supported mconsole commands.
+
+
+halt and reboot
+---------------
+
+These commands take no arguments. They shut the machine down immediately, with
+no syncing of disks and no clean shutdown of userspace. So, they are
+pretty close to crashing the machine::
+
+ (mconsole) halt
+ OK
+
+config
+------
+
+"config" adds a new device to the virtual machine. This is supported
+by most UML device drivers. It takes one argument, which is the
+device to add, with the same syntax as the kernel command line::
+
+ (mconsole) config ubd3=/home/jdike/incoming/roots/root_fs_debian22
+
+remove
+------
+
+"remove" deletes a device from the system. Its argument is just the
+name of the device to be removed. The device must be idle in whatever
+sense the driver considers necessary. In the case of the ubd driver,
+the removed block device must not be mounted, swapped on, or otherwise
+open, and in the case of the network driver, the device must be down::
+
+ (mconsole) remove ubd3
+
+sysrq
+-----
+
+This command takes one argument, which is a single letter. It calls the
+generic kernel's SysRq driver, which does whatever is called for by
+that argument. See the SysRq documentation in
+Documentation/admin-guide/sysrq.rst in your favorite kernel tree to
+see what letters are valid and what they do.
+
+cad
+---
+
+This invokes the ``Ctl-Alt-Del`` action in the running image. What exactly
+this ends up doing is up to init, systemd, etc. Normally, it reboots the
+machine.
+
+stop
+----
+
+This puts the UML in a loop reading mconsole requests until a 'go'
+mconsole command is received. This is very useful as a
+debugging/snapshotting tool.
+
+go
+--
+
+This resumes a UML after being paused by a 'stop' command. Note that
+when the UML has resumed, TCP connections may have timed out and if
+the UML is paused for a long period of time, crond might go a little
+crazy, running all the jobs it didn't do earlier.
+
+proc
+----
+
+This takes one argument - the name of a file in /proc which is printed
+to the mconsole standard output
+
+stack
+-----
+
+This takes one argument - the pid number of a process. Its stack is
+printed to a standard output.

+
+Sharing Filesystems between Virtual Machines
+============================================
+
+Don't attempt to share filesystems simply by booting two UMLs from the
+same file. That's the same thing as booting two physical machines
+from a shared disk. It will result in filesystem corruption.
+
+Using layered block devices
+---------------------------
+
+The way to share a filesystem between two virtual machines is to use
+the copy-on-write (COW) layering capability of the ubd block driver.
+Any changed blocks are stored in the private COW file, while reads come
+from either device - the private one if the requested block is valid in
+it, the shared one if not. Using this scheme, the majority of data
+which is unchanged is shared between an arbitrary number of virtual
+machines, each of which has a much smaller file containing the changes
+that it has made. With a large number of UMLs booting from a large root
+filesystem, this leads to a huge disk space saving.
+
+Sharing file system data will also help performance, since the host will
+be able to cache the shared data using a much smaller amount of memory,
+so UML disk requests will be served from the host's memory rather than
+its disks. There is a major caveat in doing this on multisocket NUMA
+machines. On such hardware, running many UML instances with a shared
+master image and COW changes may caise issues like NMIs from excess of
+inter-socket traffic.
+
+If you are running UML on high end hardware like this, make sure to
+bind UML to a set of logical cpus residing on the same socket using the
+``taskset`` command or have a look at the "tuning" section.
+
+To add a copy-on-write layer to an existing block device file, simply
+add the name of the COW file to the appropriate ubd switch::
+
+ ubd0=root_fs_cow,root_fs_debian_22
+
+where ``root_fs_cow`` is the private COW file and ``root_fs_debian_22`` is
+the existing shared filesystem. The COW file need not exist. If it
+doesn't, the driver will create and initialize it.
+
+Disk Usage
+----------
+
+UML has TRIM support which will release any unused space in its disk
+image files to the underlying OS. It is important to use either ls -ls
+or du to verify the actual file size.
+
+COW validity.
+-------------
+
+Any changes to the master image will invalidate all COW files. If this
+happens, UML will *NOT* automatically delete any of the COW files and
+will refuse to boot. In this case the only solution is to either
+restore the old image (including its last modified timestamp) or remove
+all COW files which will result in their recreation. Any changes in
+the COW files will be lost.
+
+Cows can moo - uml_moo : Merging a COW file with its backing file
+-----------------------------------------------------------------
+
+Depending on how you use UML and COW devices, it may be advisable to
+merge the changes in the COW file into the backing file every once in
+a while.
+
+The utility that does this is uml_moo. Its usage is::
+
+ uml_moo COW_file new_backing_file
+
+
+There's no need to specify the backing file since that information is
+already in the COW file header. If you're paranoid, boot the new
+merged file, and if you're happy with it, move it over the old backing
+file.
+
+``uml_moo`` creates a new backing file by default as a safety measure.
+It also has a destructive merge option which will merge the COW file
+directly into its current backing file. This is really only usable
+when the backing file only has one COW file associated with it. If
+there are multiple COWs associated with a backing file, a -d merge of
+one of them will invalidate all of the others. However, it is
+convenient if you're short of disk space, and it should also be
+noticeably faster than a non-destructive merge.
+
+``uml_moo`` is installed with the UML distribution packages and is
+available as a part of UML utilities.
+
+Host file access
+==================
+
+If you want to access files on the host machine from inside UML, you
+can treat it as a separate machine and either nfs mount directories
+from the host or copy files into the virtual machine with scp.
+However, since UML is running on the host, it can access those
+files just like any other process and make them available inside the
+virtual machine without the need to use the network.
+This is possible with the hostfs virtual filesystem. With it, you
+can mount a host directory into the UML filesystem and access the
+files contained in it just as you would on the host.
+
+*SECURITY WARNING*
+
+Hostfs without any parameters to the UML Image will allow the image
+to mount any part of the host filesystem and write to it. Always
+confine hostfs to a specific "harmless" directory (for example ``/var/tmp``)
+if running UML. This is especially important if UML is being run as root.
+
+Using hostfs
+------------
+
+To begin with, make sure that hostfs is available inside the virtual
+machine with::
+
+ # cat /proc/filesystems
+
+``hostfs`` should be listed. If it's not, either rebuild the kernel
+with hostfs configured into it or make sure that hostfs is built as a
+module and available inside the virtual machine, and insmod it.
+
+
+Now all you need to do is run mount::
+
+ # mount none /mnt/host -t hostfs
+
+will mount the host's ``/`` on the virtual machine's ``/mnt/host``.
+If you don't want to mount the host root directory, then you can
+specify a subdirectory to mount with the -o switch to mount::
+
+ # mount none /mnt/home -t hostfs -o /home
+
+will mount the hosts's /home on the virtual machine's /mnt/home.
+
+hostfs as the root filesystem
+-----------------------------
+
+It's possible to boot from a directory hierarchy on the host using
+hostfs rather than using the standard filesystem in a file.
+To start, you need that hierarchy. The easiest way is to loop mount
+an existing root_fs file::
+
+ # mount root_fs uml_root_dir -o loop
+
+
+You need to change the filesystem type of ``/`` in ``etc/fstab`` to be
+'hostfs', so that line looks like this::
+
+ /dev/ubd/0 / hostfs defaults 1 1
+
+Then you need to chown to yourself all the files in that directory
+that are owned by root. This worked for me::
+
+ # find . -uid 0 -exec chown jdike {} \;
+
+Next, make sure that your UML kernel has hostfs compiled in, not as a
+module. Then run UML with the boot device pointing at that directory::
+
+ ubd0=/path/to/uml/root/directory
+
+UML should then boot as it does normally.
+
+Hostfs Caveats
+--------------
+
+Hostfs does not support keeping track of host filesystem changes on the
+host (outside UML). As a result, if a file is changed without UML's
+knowledge, UML will not know about it and its own in-memory cache of
+the file may be corrupt. While it is possible to fix this, it is not
+something which is being worked on at present.
+
+Tuning UML
+============
+
+UML at present is strictly uniprocessor. It will, however spin up a
+number of threads to handle various functions.
+
+The UBD driver, SIGIO and the MMU emulation do that. If the system is
+idle, these threads will be migrated to other processors on a SMP host.
+This, unfortunately, will usually result in LOWER performance because of
+all of the cache/memory synchronization traffic between cores. As a
+result, UML will usually benefit from being pinned on a single CPU
+especially on a large system. This can result in performance differences
+of 5 times or higher on some benchmarks.
+
+Similarly, on large multi-node NUMA systems UML will benefit if all of
+its memory is allocated from the same NUMA node it will run on. The
+OS will *NOT* do that by default. In order to do that, the sysadmin
+needs to create a suitable tmpfs ramdisk bound to a particular node
+and use that as the source for UML RAM allocation by specifying it
+in the TMP or TEMP environment variables. UML will look at the values
+of ``TMPDIR``, ``TMP`` or ``TEMP`` for that. If that fails, it will
+look for shmfs mounted under ``/dev/shm``. If everything else fails use
+``/tmp/`` regardless of the filesystem type used for it::
+
+ mount -t tmpfs -ompol=bind:X none /mnt/tmpfs-nodeX
+ TEMP=/mnt/tmpfs-nodeX taskset -cX linux options options options..

+*******************************************
+Contributing to UML and Developing with UML
+*******************************************
+
+UML is an excellent platform to develop new Linux kernel concepts -
+filesystems, devices, virtualization, etc. It provides unrivalled
+opportunities to create and test them without being constrained to
+emulating specific hardware.
+
+Example - want to try how linux will work with 4096 "proper" network
+devices?
+
+Not an issue with UML. At the same time, this is something which
+is difficult with other virtualization packages - they are
+constrained by the number of devices allowed on the hardware bus
+they are trying to emulate (for example 16 on a PCI bus in qemu).
+
+If you have something to contribute such as a patch, a bugfix, a
+new feature, please send it to ``linux-um@lists.infradead.org``
+
+Please follow all standard Linux patch guidelines such as cc-ing
+relevant maintainers and run ``./sripts/checkpatch.pl`` on your patch.
+For more details see ``Documentation/process/submitting-patches.rst``
+
+Note - the list does not accept HTML or attachments, all emails must
+be formatted as plain text.
+
+Developing always goes hand in hand with debugging. First of all,
+you can always run UML under gdb and there will be a whole section
+later on on how to do that. That, however, is not the only way to
+debug a linux kernel. Quite often adding tracing statements and/or
+using UML specific approaches such as ptracing the UML kernel process
+are significantly more informative.
+
+Tracing UML
+=============
+
+When running UML consists of a main kernel thread and a number of
+helper threads. The ones of interest for tracing are NOT the ones
+that are already ptraced by UML as a part of its MMU emulation.
+
+These are usually the first three threads visible in a ps display.
+The one with the lowest PID number and using most CPU is usually the
+kernel thread. The other threads are the disk
+(ubd) device helper thread and the sigio helper thread.
+Running ptrace on this thread usually results in the following picture::
+
+ host$ strace -p 16566
+ --- SIGIO {si_signo=SIGIO, si_code=POLL_IN, si_band=65} ---
+ epoll_wait(4, [{EPOLLIN, {u32=3721159424, u64=3721159424}}], 64, 0) = 1
+ epoll_wait(4, [], 64, 0) = 0
+ rt_sigreturn({mask=[PIPE]}) = 16967
+ ptrace(PTRACE_GETREGS, 16967, NULL, 0xd5f34f38) = 0
+ ptrace(PTRACE_GETREGSET, 16967, NT_X86_XSTATE, [{iov_base=0xd5f35010, iov_len=832}]) = 0
+ ptrace(PTRACE_GETSIGINFO, 16967, NULL, {si_signo=SIGTRAP, si_code=0x85, si_pid=16967, si_uid=0}) = 0
+ ptrace(PTRACE_SETREGS, 16967, NULL, 0xd5f34f38) = 0
+ ptrace(PTRACE_SETREGSET, 16967, NT_X86_XSTATE, [{iov_base=0xd5f35010, iov_len=2696}]) = 0
+ ptrace(PTRACE_SYSEMU, 16967, NULL, 0) = 0
+ --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_TRAPPED, si_pid=16967, si_uid=0, si_status=SIGTRAP, si_utime=65, si_stime=89} ---
+ wait4(16967, [{WIFSTOPPED(s) && WSTOPSIG(s) == SIGTRAP | 0x80}], WSTOPPED|__WALL, NULL) = 16967
+ ptrace(PTRACE_GETREGS, 16967, NULL, 0xd5f34f38) = 0
+ ptrace(PTRACE_GETREGSET, 16967, NT_X86_XSTATE, [{iov_base=0xd5f35010, iov_len=832}]) = 0
+ ptrace(PTRACE_GETSIGINFO, 16967, NULL, {si_signo=SIGTRAP, si_code=0x85, si_pid=16967, si_uid=0}) = 0
+ timer_settime(0, 0, {it_interval={tv_sec=0, tv_nsec=0}, it_value={tv_sec=0, tv_nsec=2830912}}, NULL) = 0
+ getpid() = 16566
+ clock_nanosleep(CLOCK_MONOTONIC, 0, {tv_sec=1, tv_nsec=0}, NULL) = ? ERESTART_RESTARTBLOCK (Interrupted by signal)
+ --- SIGALRM {si_signo=SIGALRM, si_code=SI_TIMER, si_timerid=0, si_overrun=0, si_value={int=1631716592, ptr=0x614204f0}} ---
+ rt_sigreturn({mask=[PIPE]}) = -1 EINTR (Interrupted system call)
+
+This is a typical picture from a mostly idle UML instance
+
+* UML interrupt controller uses epoll - this is UML waiting for IO
+ interrupts:
+
+ epoll_wait(4, [{EPOLLIN, {u32=3721159424, u64=3721159424}}], 64, 0) = 1
+
+* The sequence of ptrace calls is part of MMU emulation and runnin the
+ UML userspace
+* ``timer_settime`` is part of the UML high res timer subsystem mapping
+ timer requests from inside UML onto the host high resultion timers.
+* ``clock_nanosleep`` is UML going into idle (similar to the way a PC
+ will execute an ACPI idle).
+
+As you can see UML will generate quite a bit of output even in idle.The output
+can be very informative when observing IO. It shows the actual IO calls, their
+arguments and returns values.
+
+Kernel debugging
+================
+
+You can run UML under gdb now, though it will not necessarily agree to
+be started under it. If you are trying to track a runtime bug, it is
+much better to attach gdb to a running UML instance and let UML run.
+
+Assuming the same PID number as in the previous example, this would be::
+
+ # gdb -p 16566
+
+This will STOP the UML instance, so you must enter `cont` at the GDB
+command line to request it to continue. It may be a good idea to make
+this into a gdb script and pass it to gdb as an argument.
+
+Developing Device Drivers
+=========================
+
+Nearly all UML drivers are monolithic. While it is possible to build a
+UML driver as a kernel module, that limits the possible functionality
+to in-kernel only and non-UML specific. The reason for this is that
+in order to really leverage UML, one needs to write a piece of
+userspace code which maps driver concepts onto actual userspace host
+calls.
+
+This forms the so called "user" portion of the driver. While it can
+reuse a lot of kernel concepts, it is generally just another piece of
+userspace code. This portion needs some matching "kernel" code which
+resides inside the UML image and which implements the Linux kernel part.
+
+*Note: There are very few limitations in the way "kernel" and "user" interact*.
+
+UML does not have a strictly defined kernel to host API. It does not
+try to emulate a specific architecture or bus. UML's "kernel" and
+"user" can share memory, code and interact as needed to implement
+whatever design the software developer has in mind. The only
+limitations are purely technical. Due to a lot of functions and
+variables having the same names, the developer should be careful
+which includes and libraries they are trying to refer to.
+
+As a result a lot of userspace code consists of simple wrappers.
+F.e. ``os_close_file()`` is just a wrapper around ``close()``
+which ensures that the userspace function close does not clash
+with similarly named function(s) in the kernel part.
+
+Security Considerations
+-----------------------
+
+Drivers or any new functionality should default to not
+accepting arbitrary filename, bpf code or other parameters
+which can affect the host from inside the UML instance.
+For example, specifying the socket used for IPC communication
+between a driver and the host at the UML command line is OK
+security-wise. Allowing it as a loadable module parameter
+isn't.
+
+If such functionality is desireable for a particular application
+(e.g. loading BPF "firmware" for raw socket network transports),
+it should be off by default and should be explicitly turned on
+as a command line parameter at startup.
+
+Even with this in mind, the level of isolation between UML
+and the host is relatively weak. If the UML userspace is
+allowed to load arbitrary kernel drivers, an attacker can
+use this to break out of UML. Thus, if UML is used in
+a production application, it is recommended that all modules
+are loaded at boot and kernel module loading is disabled
+afterwards.

Migration to and from device memory
===================================
-Because the CPU cannot access device memory, migration must use the device DMA
-engine to perform copy from and to device memory. For this we need to use
-migrate_vma_setup(), migrate_vma_pages(), and migrate_vma_finalize() helpers.
-
+Because the CPU cannot access device memory directly, the device driver must
+use hardware DMA or device specific load/store instructions to migrate data.
+The migrate_vma_setup(), migrate_vma_pages(), and migrate_vma_finalize()
+functions are designed to make drivers easier to write and to centralize common
+code across drivers.
+
+Before migrating pages to device private memory, special device private
+``struct page`` need to be created. These will be used as special "swap"
+page table entries so that a CPU process will fault if it tries to access
+a page that has been migrated to device private memory.
+
+These can be allocated and freed with::
+
+ struct resource *res;
+ struct dev_pagemap pagemap;
+
+ res = request_free_mem_region(&iomem_resource, /* number of bytes */,
+ "name of driver resource");
+ pagemap.type = MEMORY_DEVICE_PRIVATE;
+ pagemap.range.start = res->start;
+ pagemap.range.end = res->end;
+ pagemap.nr_range = 1;
+ pagemap.ops = &device_devmem_ops;
+ memremap_pages(&pagemap, numa_node_id());
+
+ memunmap_pages(&pagemap);
+ release_mem_region(pagemap.range.start, range_len(&pagemap.range));
+
+There are also devm_request_free_mem_region(), devm_memremap_pages(),
+devm_memunmap_pages(), and devm_release_mem_region() when the resources can
+be tied to a ``struct device``.
+
+The overall migration steps are similar to migrating NUMA pages within system
+memory (see :ref:`Page migration <page_migration>`) but the steps are split
+between device driver specific code and shared common code:
+
+1. ``mmap_read_lock()``
+
+ The device driver has to pass a ``struct vm_area_struct`` to
+ migrate_vma_setup() so the mmap_read_lock() or mmap_write_lock() needs to
+ be held for the duration of the migration.
+
+2. ``migrate_vma_setup(struct migrate_vma *args)``
+
+ The device driver initializes the ``struct migrate_vma`` fields and passes
+ the pointer to migrate_vma_setup(). The ``args->flags`` field is used to
+ filter which source pages should be migrated. For example, setting
+ ``MIGRATE_VMA_SELECT_SYSTEM`` will only migrate system memory and
+ ``MIGRATE_VMA_SELECT_DEVICE_PRIVATE`` will only migrate pages residing in
+ device private memory. If the latter flag is set, the ``args->pgmap_owner``
+ field is used to identify device private pages owned by the driver. This
+ avoids trying to migrate device private pages residing in other devices.
+ Currently only anonymous private VMA ranges can be migrated to or from
+ system memory and device private memory.
+
+ One of the first steps migrate_vma_setup() does is to invalidate other
+ device's MMUs with the ``mmu_notifier_invalidate_range_start(()`` and
+ ``mmu_notifier_invalidate_range_end()`` calls around the page table
+ walks to fill in the ``args->src`` array with PFNs to be migrated.
+ The ``invalidate_range_start()`` callback is passed a
+ ``struct mmu_notifier_range`` with the ``event`` field set to
+ ``MMU_NOTIFY_MIGRATE`` and the ``migrate_pgmap_owner`` field set to
+ the ``args->pgmap_owner`` field passed to migrate_vma_setup(). This is
+ allows the device driver to skip the invalidation callback and only
+ invalidate device private MMU mappings that are actually migrating.
+ This is explained more in the next section.
+
+ While walking the page tables, a ``pte_none()`` or ``is_zero_pfn()``
+ entry results in a valid "zero" PFN stored in the ``args->src`` array.
+ This lets the driver allocate device private memory and clear it instead
+ of copying a page of zeros. Valid PTE entries to system memory or
+ device private struct pages will be locked with ``lock_page()``, isolated
+ from the LRU (if system memory since device private pages are not on
+ the LRU), unmapped from the process, and a special migration PTE is
+ inserted in place of the original PTE.
+ migrate_vma_setup() also clears the ``args->dst`` array.
+
+3. The device driver allocates destination pages and copies source pages to
+ destination pages.
+
+ The driver checks each ``src`` entry to see if the ``MIGRATE_PFN_MIGRATE``
+ bit is set and skips entries that are not migrating. The device driver
+ can also choose to skip migrating a page by not filling in the ``dst``
+ array for that page.
+
+ The driver then allocates either a device private struct page or a
+ system memory page, locks the page with ``lock_page()``, and fills in the
+ ``dst`` array entry with::
+
+ dst[i] = migrate_pfn(page_to_pfn(dpage)) | MIGRATE_PFN_LOCKED;
+
+ Now that the driver knows that this page is being migrated, it can
+ invalidate device private MMU mappings and copy device private memory
+ to system memory or another device private page. The core Linux kernel
+ handles CPU page table invalidations so the device driver only has to
+ invalidate its own MMU mappings.
+
+ The driver can use ``migrate_pfn_to_page(src[i])`` to get the
+ ``struct page`` of the source and either copy the source page to the
+ destination or clear the destination device private memory if the pointer
+ is ``NULL`` meaning the source page was not populated in system memory.
+
+4. ``migrate_vma_pages()``
+
+ This step is where the migration is actually "committed".
+
+ If the source page was a ``pte_none()`` or ``is_zero_pfn()`` page, this
+ is where the newly allocated page is inserted into the CPU's page table.
+ This can fail if a CPU thread faults on the same page. However, the page
+ table is locked and only one of the new pages will be inserted.
+ The device driver will see that the ``MIGRATE_PFN_MIGRATE`` bit is cleared
+ if it loses the race.
+
+ If the source page was locked, isolated, etc. the source ``struct page``
+ information is now copied to destination ``struct page`` finalizing the
+ migration on the CPU side.
+
+5. Device driver updates device MMU page tables for pages still migrating,
+ rolling back pages not migrating.
+
+ If the ``src`` entry still has ``MIGRATE_PFN_MIGRATE`` bit set, the device
+ driver can update the device MMU and set the write enable bit if the
+ ``MIGRATE_PFN_WRITE`` bit is set.
+
+6. ``migrate_vma_finalize()``
+
+ This step replaces the special migration page table entry with the new
+ page's page table entry and releases the reference to the source and
+ destination ``struct page``.
+
+7. ``mmap_read_unlock()``
+
+ The lock can now be released.

+x86 Feature Flags
+=================
+
+Introduction
+============
+
+On x86, flags appearing in /proc/cpuinfo have an X86_FEATURE definition
+in arch/x86/include/asm/cpufeatures.h. If the kernel cares about a feature
+or KVM want to expose the feature to a KVM guest, it can and should have
+an X86_FEATURE_* defined. These flags represent hardware features as
+well as software features.
+
+If users want to know if a feature is available on a given system, they
+try to find the flag in /proc/cpuinfo. If a given flag is present, it
+means that the kernel supports it and is currently making it available.
+If such flag represents a hardware feature, it also means that the
+hardware supports it.
+
+If the expected flag does not appear in /proc/cpuinfo, things are murkier.
+Users need to find out the reason why the flag is missing and find the way
+how to enable it, which is not always easy. There are several factors that
+can explain missing flags: the expected feature failed to enable, the feature
+is missing in hardware, platform firmware did not enable it, the feature is
+disabled at build or run time, an old kernel is in use, or the kernel does
+not support the feature and thus has not enabled it. In general, /proc/cpuinfo
+shows features which the kernel supports. For a full list of CPUID flags
+which the CPU supports, use tools/arch/x86/kcpuid.
+
+How are feature flags created?
+==============================
+
+a: Feature flags can be derived from the contents of CPUID leaves.
+------------------------------------------------------------------
+These feature definitions are organized mirroring the layout of CPUID
+leaves and grouped in words with offsets as mapped in enum cpuid_leafs
+in cpufeatures.h (see arch/x86/include/asm/cpufeatures.h for details).
+If a feature is defined with a X86_FEATURE_<name> definition in
+cpufeatures.h, and if it is detected at run time, the flags will be
+displayed accordingly in /proc/cpuinfo. For example, the flag "avx2"
+comes from X86_FEATURE_AVX2 in cpufeatures.h.
+
+b: Flags can be from scattered CPUID-based features.
+----------------------------------------------------
+Hardware features enumerated in sparsely populated CPUID leaves get
+software-defined values. Still, CPUID needs to be queried to determine
+if a given feature is present. This is done in init_scattered_cpuid_features().
+For instance, X86_FEATURE_CQM_LLC is defined as 11*32 + 0 and its presence is
+checked at runtime in the respective CPUID leaf [EAX=f, ECX=0] bit EDX[1].
+
+The intent of scattering CPUID leaves is to not bloat struct
+cpuinfo_x86.x86_capability[] unnecessarily. For instance, the CPUID leaf
+[EAX=7, ECX=0] has 30 features and is dense, but the CPUID leaf [EAX=7, EAX=1]
+has only one feature and would waste 31 bits of space in the x86_capability[]
+array. Since there is a struct cpuinfo_x86 for each possible CPU, the wasted
+memory is not trivial.
+
+c: Flags can be created synthetically under certain conditions for hardware features.
+-------------------------------------------------------------------------------------
+Examples of conditions include whether certain features are present in
+MSR_IA32_CORE_CAPS or specific CPU models are identified. If the needed
+conditions are met, the features are enabled by the set_cpu_cap or
+setup_force_cpu_cap macros. For example, if bit 5 is set in MSR_IA32_CORE_CAPS,
+the feature X86_FEATURE_SPLIT_LOCK_DETECT will be enabled and
+"split_lock_detect" will be displayed. The flag "ring3mwait" will be
+displayed only when running on INTEL_FAM6_XEON_PHI_[KNL|KNM] processors.
+
+d: Flags can represent purely software features.
+------------------------------------------------
+These flags do not represent hardware features. Instead, they represent a
+software feature implemented in the kernel. For example, Kernel Page Table
+Isolation is purely software feature and its feature flag X86_FEATURE_PTI is
+also defined in cpufeatures.h.
+
+Naming of Flags
+===============
+
+The script arch/x86/kernel/cpu/mkcapflags.sh processes the
+#define X86_FEATURE_<name> from cpufeatures.h and generates the
+x86_cap/bug_flags[] arrays in kernel/cpu/capflags.c. The names in the
+resulting x86_cap/bug_flags[] are used to populate /proc/cpuinfo. The naming
+of flags in the x86_cap/bug_flags[] are as follows:
+
+a: The name of the flag is from the string in X86_FEATURE_<name> by default.
+----------------------------------------------------------------------------
+By default, the flag <name> in /proc/cpuinfo is extracted from the respective
+X86_FEATURE_<name> in cpufeatures.h. For example, the flag "avx2" is from
+X86_FEATURE_AVX2.
+
+b: The naming can be overridden.
+--------------------------------
+If the comment on the line for the #define X86_FEATURE_* starts with a
+double-quote character (""), the string inside the double-quote characters
+will be the name of the flags. For example, the flag "sse4_1" comes from
+the comment "sse4_1" following the X86_FEATURE_XMM4_1 definition.
+
+There are situations in which overriding the displayed name of the flag is
+needed. For instance, /proc/cpuinfo is a userspace interface and must remain
+constant. If, for some reason, the naming of X86_FEATURE_<name> changes, one
+shall override the new naming with the name already used in /proc/cpuinfo.
+
+c: The naming override can be "", which means it will not appear in /proc/cpuinfo.
+----------------------------------------------------------------------------------
+The feature shall be omitted from /proc/cpuinfo if it does not make sense for
+the feature to be exposed to userspace. For example, X86_FEATURE_ALWAYS is
+defined in cpufeatures.h but that flag is an internal kernel feature used
+in the alternative runtime patching functionality. So, its name is overridden
+with "". Its flag will not appear in /proc/cpuinfo.
+
+Flags are missing when one or more of these happen
+==================================================
+
+a: The hardware does not enumerate support for it.
+--------------------------------------------------
+For example, when a new kernel is running on old hardware or the feature is
+not enabled by boot firmware. Even if the hardware is new, there might be a
+problem enabling the feature at run time, the flag will not be displayed.
+
+b: The kernel does not know about the flag.
+-------------------------------------------
+For example, when an old kernel is running on new hardware.
+
+c: The kernel disabled support for it at compile-time.
+------------------------------------------------------
+For example, if 5-level-paging is not enabled when building (i.e.,
+CONFIG_X86_5LEVEL is not selected) the flag "la57" will not show up [#f1]_.
+Even though the feature will still be detected via CPUID, the kernel disables
+it by clearing via setup_clear_cpu_cap(X86_FEATURE_LA57).
+
+d: The feature is disabled at boot-time.
+----------------------------------------
+A feature can be disabled either using a command-line parameter or because
+it failed to be enabled. The command-line parameter clearcpuid= can be used
+to disable features using the feature number as defined in
+/arch/x86/include/asm/cpufeatures.h. For instance, User Mode Instruction
+Protection can be disabled using clearcpuid=514. The number 514 is calculated
+from #define X86_FEATURE_UMIP (16*32 + 2).
+
+In addition, there exists a variety of custom command-line parameters that
+disable specific features. The list of parameters includes, but is not limited
+to, nofsgsbase, nosmap, and nosmep. 5-level paging can also be disabled using
+"no5lvl". SMAP and SMEP are disabled with the aforementioned parameters,
+respectively.
+
+e: The feature was known to be non-functional.
+----------------------------------------------
+The feature was known to be non-functional because a dependency was
+missing at runtime. For example, AVX flags will not show up if XSAVE feature
+is disabled since they depend on XSAVE feature. Another example would be broken
+CPUs and them missing microcode patches. Due to that, the kernel decides not to
+enable a feature.
+
+.. [#f1] 5-level paging uses linear address of 57 bits.

+===========================================
+Shared Virtual Addressing (SVA) with ENQCMD
+===========================================
+
+Background
+==========
+
+Shared Virtual Addressing (SVA) allows the processor and device to use the
+same virtual addresses avoiding the need for software to translate virtual
+addresses to physical addresses. SVA is what PCIe calls Shared Virtual
+Memory (SVM).
+
+In addition to the convenience of using application virtual addresses
+by the device, it also doesn't require pinning pages for DMA.
+PCIe Address Translation Services (ATS) along with Page Request Interface
+(PRI) allow devices to function much the same way as the CPU handling
+application page-faults. For more information please refer to the PCIe
+specification Chapter 10: ATS Specification.
+
+Use of SVA requires IOMMU support in the platform. IOMMU is also
+required to support the PCIe features ATS and PRI. ATS allows devices
+to cache translations for virtual addresses. The IOMMU driver uses the
+mmu_notifier() support to keep the device TLB cache and the CPU cache in
+sync. When an ATS lookup fails for a virtual address, the device should
+use the PRI in order to request the virtual address to be paged into the
+CPU page tables. The device must use ATS again in order the fetch the
+translation before use.
+
+Shared Hardware Workqueues
+==========================
+
+Unlike Single Root I/O Virtualization (SR-IOV), Scalable IOV (SIOV) permits
+the use of Shared Work Queues (SWQ) by both applications and Virtual
+Machines (VM's). This allows better hardware utilization vs. hard
+partitioning resources that could result in under utilization. In order to
+allow the hardware to distinguish the context for which work is being
+executed in the hardware by SWQ interface, SIOV uses Process Address Space
+ID (PASID), which is a 20-bit number defined by the PCIe SIG.
+
+PASID value is encoded in all transactions from the device. This allows the
+IOMMU to track I/O on a per-PASID granularity in addition to using the PCIe
+Resource Identifier (RID) which is the Bus/Device/Function.
+
+
+ENQCMD
+======
+
+ENQCMD is a new instruction on Intel platforms that atomically submits a
+work descriptor to a device. The descriptor includes the operation to be
+performed, virtual addresses of all parameters, virtual address of a completion
+record, and the PASID (process address space ID) of the current process.
+
+ENQCMD works with non-posted semantics and carries a status back if the
+command was accepted by hardware. This allows the submitter to know if the
+submission needs to be retried or other device specific mechanisms to
+implement fairness or ensure forward progress should be provided.
+
+ENQCMD is the glue that ensures applications can directly submit commands
+to the hardware and also permits hardware to be aware of application context
+to perform I/O operations via use of PASID.
+
+Process Address Space Tagging
+=============================
+
+A new thread-scoped MSR (IA32_PASID) provides the connection between
+user processes and the rest of the hardware. When an application first
+accesses an SVA-capable device, this MSR is initialized with a newly
+allocated PASID. The driver for the device calls an IOMMU-specific API
+that sets up the routing for DMA and page-requests.
+
+For example, the Intel Data Streaming Accelerator (DSA) uses
+iommu_sva_bind_device(), which will do the following:
+
+- Allocate the PASID, and program the process page-table (%cr3 register) in the
+ PASID context entries.
+- Register for mmu_notifier() to track any page-table invalidations to keep
+ the device TLB in sync. For example, when a page-table entry is invalidated,
+ the IOMMU propagates the invalidation to the device TLB. This will force any
+ future access by the device to this virtual address to participate in
+ ATS. If the IOMMU responds with proper response that a page is not
+ present, the device would request the page to be paged in via the PCIe PRI
+ protocol before performing I/O.
+
+This MSR is managed with the XSAVE feature set as "supervisor state" to
+ensure the MSR is updated during context switch.
+
+PASID Management
+================
+
+The kernel must allocate a PASID on behalf of each process which will use
+ENQCMD and program it into the new MSR to communicate the process identity to
+platform hardware. ENQCMD uses the PASID stored in this MSR to tag requests
+from this process. When a user submits a work descriptor to a device using the
+ENQCMD instruction, the PASID field in the descriptor is auto-filled with the
+value from MSR_IA32_PASID. Requests for DMA from the device are also tagged
+with the same PASID. The platform IOMMU uses the PASID in the transaction to
+perform address translation. The IOMMU APIs setup the corresponding PASID
+entry in IOMMU with the process address used by the CPU (e.g. %cr3 register in
+x86).
+
+The MSR must be configured on each logical CPU before any application
+thread can interact with a device. Threads that belong to the same
+process share the same page tables, thus the same MSR value.
+
+PASID is cleared when a process is created. The PASID allocation and MSR
+programming may occur long after a process and its threads have been created.
+One thread must call iommu_sva_bind_device() to allocate the PASID for the
+process. If a thread uses ENQCMD without the MSR first being populated, a #GP
+will be raised. The kernel will update the PASID MSR with the PASID for all
+threads in the process. A single process PASID can be used simultaneously
+with multiple devices since they all share the same address space.
+
+One thread can call iommu_sva_unbind_device() to free the allocated PASID.
+The kernel will clear the PASID MSR for all threads belonging to the process.
+
+New threads inherit the MSR value from the parent.
+
+Relationships
+=============
+
+ * Each process has many threads, but only one PASID.
+ * Devices have a limited number (~10's to 1000's) of hardware workqueues.
+ The device driver manages allocating hardware workqueues.
+ * A single mmap() maps a single hardware workqueue as a "portal" and
+ each portal maps down to a single workqueue.
+ * For each device with which a process interacts, there must be
+ one or more mmap()'d portals.
+ * Many threads within a process can share a single portal to access
+ a single device.
+ * Multiple processes can separately mmap() the same portal, in
+ which case they still share one device hardware workqueue.
+ * The single process-wide PASID is used by all threads to interact
+ with all devices. There is not, for instance, a PASID for each
+ thread or each thread<->device pair.
+
+FAQ
+===
+
+* What is SVA/SVM?
+
+Shared Virtual Addressing (SVA) permits I/O hardware and the processor to
+work in the same address space, i.e., to share it. Some call it Shared
+Virtual Memory (SVM), but Linux community wanted to avoid confusing it with
+POSIX Shared Memory and Secure Virtual Machines which were terms already in
+circulation.
+
+* What is a PASID?
+
+A Process Address Space ID (PASID) is a PCIe-defined Transaction Layer Packet
+(TLP) prefix. A PASID is a 20-bit number allocated and managed by the OS.
+PASID is included in all transactions between the platform and the device.
+
+* How are shared workqueues different?
+
+Traditionally, in order for userspace applications to interact with hardware,
+there is a separate hardware instance required per process. For example,
+consider doorbells as a mechanism of informing hardware about work to process.
+Each doorbell is required to be spaced 4k (or page-size) apart for process
+isolation. This requires hardware to provision that space and reserve it in
+MMIO. This doesn't scale as the number of threads becomes quite large. The
+hardware also manages the queue depth for Shared Work Queues (SWQ), and
+consumers don't need to track queue depth. If there is no space to accept
+a command, the device will return an error indicating retry.
+
+A user should check Deferrable Memory Write (DMWr) capability on the device
+and only submits ENQCMD when the device supports it. In the new DMWr PCIe
+terminology, devices need to support DMWr completer capability. In addition,
+it requires all switch ports to support DMWr routing and must be enabled by
+the PCIe subsystem, much like how PCIe atomic operations are managed for
+instance.
+
+SWQ allows hardware to provision just a single address in the device. When
+used with ENQCMD to submit work, the device can distinguish the process
+submitting the work since it will include the PASID assigned to that
+process. This helps the device scale to a large number of processes.
+
+* Is this the same as a user space device driver?
+
+Communicating with the device via the shared workqueue is much simpler
+than a full blown user space driver. The kernel driver does all the
+initialization of the hardware. User space only needs to worry about
+submitting work and processing completions.
+
+* Is this the same as SR-IOV?
+
+Single Root I/O Virtualization (SR-IOV) focuses on providing independent
+hardware interfaces for virtualizing hardware. Hence, it's required to be
+almost fully functional interface to software supporting the traditional
+BARs, space for interrupts via MSI-X, its own register layout.
+Virtual Functions (VFs) are assisted by the Physical Function (PF)
+driver.
+
+Scalable I/O Virtualization builds on the PASID concept to create device
+instances for virtualization. SIOV requires host software to assist in
+creating virtual devices; each virtual device is represented by a PASID
+along with the bus/device/function of the device. This allows device
+hardware to optimize device resource creation and can grow dynamically on
+demand. SR-IOV creation and management is very static in nature. Consult
+references below for more details.
+
+* Why not just create a virtual function for each app?
+
+Creating PCIe SR-IOV type Virtual Functions (VF) is expensive. VFs require
+duplicated hardware for PCI config space and interrupts such as MSI-X.
+Resources such as interrupts have to be hard partitioned between VFs at
+creation time, and cannot scale dynamically on demand. The VFs are not
+completely independent from the Physical Function (PF). Most VFs require
+some communication and assistance from the PF driver. SIOV, in contrast,
+creates a software-defined device where all the configuration and control
+aspects are mediated via the slow path. The work submission and completion
+happen without any mediation.
+
+* Does this support virtualization?
+
+ENQCMD can be used from within a guest VM. In these cases, the VMM helps
+with setting up a translation table to translate from Guest PASID to Host
+PASID. Please consult the ENQCMD instruction set reference for more
+details.
+
+* Does memory need to be pinned?
+
+When devices support SVA along with platform hardware such as IOMMU
+supporting such devices, there is no need to pin memory for DMA purposes.
+Devices that support SVA also support other PCIe features that remove the
+pinning requirement for memory.
+
+Device TLB support - Device requests the IOMMU to lookup an address before
+use via Address Translation Service (ATS) requests. If the mapping exists
+but there is no page allocated by the OS, IOMMU hardware returns that no
+mapping exists.
+
+Device requests the virtual address to be mapped via Page Request
+Interface (PRI). Once the OS has successfully completed the mapping, it
+returns the response back to the device. The device requests again for
+a translation and continues.
+
+IOMMU works with the OS in managing consistency of page-tables with the
+device. When removing pages, it interacts with the device to remove any
+device TLB entry that might have been cached before removing the mappings from
+the OS.

+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+0. PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+written document "free" in the sense of freedom: to assure everyone
+the effective freedom to copy and redistribute it, with or without
+modifying it, either commercially or noncommercially. Secondarily,
+this License preserves for the author and publisher a way to get
+credit for their work, while not being considered responsible for
+modifications made by others.
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+1. APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work that contains a
+notice placed by the copyright holder saying it can be distributed
+under the terms of this License. The "Document", below, refers to any
+such manual or work. Any member of the public is a licensee, and is
+addressed as "you".
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A "Secondary Section" is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (For example, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, whose contents can be viewed and edited directly and
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup has been designed to thwart or discourage
+subsequent modification by readers is not Transparent. A copy that is
+not "Transparent" is called "Opaque".
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML designed for human modification. Opaque formats include
+PostScript, PDF, proprietary formats that can be read and edited only
+by proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML produced by some word processors for output
+purposes only.
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+
+2. VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+3. COPYING IN QUANTITY
+
+If you publish printed copies of the Document numbering more than 100,
+and the Document's license notice requires Cover Texts, you must enclose
+the copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a publicly-accessible computer-network location containing a complete
+Transparent copy of the Document, free of added material, which the
+general network-using public has access to download anonymously at no
+charge using public-standard network protocols. If you use the latter
+option, you must take reasonably prudent steps, when you begin
+distribution of Opaque copies in quantity, to ensure that this
+Transparent copy will remain thus accessible at the stated location
+until at least one year after the last time you distribute an Opaque
+copy (directly or through your agents or retailers) of that edition to
+the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+4. MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+A. Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.
+B. List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has less than five).
+C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+D. Preserve all the copyright notices of the Document.
+E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+F. Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.
+G. Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+H. Include an unaltered copy of this License.
+I. Preserve the section entitled "History", and its title, and add to
+ it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section entitled "History" in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+J. Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the "History" section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.
+K. In any section entitled "Acknowledgements" or "Dedications",
+ preserve the section's title, and preserve in the section all the
+ substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.
+L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.
+M. Delete any section entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+N. Do not retitle any existing section as "Endorsements"
+ or to conflict in title with any Invariant Section.
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+5. COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections entitled "History"
+in the various original documents, forming one section entitled
+"History"; likewise combine any sections entitled "Acknowledgements",
+and any sections entitled "Dedications". You must delete all sections
+entitled "Endorsements."
+
+
+6. COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+7. AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, does not as a whole count as a Modified Version
+of the Document, provided no compilation copyright is claimed for the
+compilation. Such a compilation is called an "aggregate", and this
+License does not apply to the other self-contained works thus compiled
+with the Document, on account of their being thus compiled, if they
+are not themselves derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one quarter
+of the entire aggregate, the Document's Cover Texts may be placed on
+covers that surround only the Document within the aggregate.
+Otherwise they must appear on covers around the whole aggregate.
+
+
+8. TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License provided that you also include the
+original English version of this License. In case of a disagreement
+between the translation and the original English version of this
+License, the original English version will prevail.
+
+
+9. TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+
+10. FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+https://www.gnu.org/licenses/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.
+
+
+ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+ Copyright (c) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.1
+ or any later version published by the Free Software Foundation;
+ with the Invariant Sections being LIST THEIR TITLES, with the
+ Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+ A copy of the license is included in the section entitled "GNU
+ Free Documentation License".
+
+If you have no Invariant Sections, write "with no Invariant Sections"
+instead of saying which ones are invariant. If you have no
+Front-Cover Texts, write "no Front-Cover Texts" instead of
+"Front-Cover Texts being LIST"; likewise for Back-Cover Texts.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+0. PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document "free" in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+1. APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The "Document", below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as "you". You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A "Secondary Section" is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (Thus, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called "Opaque".
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification. Examples of
+transparent image formats include PNG, XCF and JPG. Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".) To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+
+2. VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+3. COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+4. MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+A. Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.
+B. List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has fewer than five),
+ unless they release you from this requirement.
+C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+D. Preserve all the copyright notices of the Document.
+E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+F. Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.
+G. Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+H. Include an unaltered copy of this License.
+I. Preserve the section Entitled "History", Preserve its Title, and add
+ to it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled "History" in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+J. Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the "History" section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.
+K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section all
+ the substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.
+L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.
+M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+N. Do not retitle any existing section to be Entitled "Endorsements"
+ or to conflict in title with any Invariant Section.
+O. Preserve any Warranty Disclaimers.
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+5. COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all sections
+Entitled "Endorsements".
+
+
+6. COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+7. AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+8. TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+9. TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+
+10. FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+https://www.gnu.org/licenses/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.
+
+
+ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+ Copyright (c) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+ A copy of the license is included in the section entitled "GNU
+ Free Documentation License".
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with the
+ Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

- On the real chip of the NPS, auxiliary registers are shared between

- each cpu has a different set of auxiliary registers. Configuration
- should be unset if auxiliary registers are not shared between the cpus
- of the core, so there will be a need to initialize them per cpu.

+ * all of the currently onlined CPUs are safelisted, as the mitigation tends to
+ * be opt-in for userspace. Yes, really, the cure is worse than the disease.

- This kernel feature is useful for number crunching applications
- that may need to compute untrusted bytecode during their
- execution. By using pipes or other transports made available to
- the process as file descriptors supporting the read/write
- syscalls, it's possible to isolate those applications in
- their own address space using seccomp. Once seccomp is
- enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
- and the task is only allowed to execute a few safe syscalls
- defined by each seccomp mode.

-* 4 use cases of Alchemy GPIOS:
-*(1) GPIOLIB=y, ALCHEMY_GPIO_INDIRECT=y:
-* Board must register gpiochips.
-*(2) GPIOLIB=y, ALCHEMY_GPIO_INDIRECT=n:
-* A gpiochip for the 75 GPIOs is registered.
-*
-*(3) GPIOLIB=n, ALCHEMY_GPIO_INDIRECT=y:
-* the boards' gpio.h must provide the linux gpio wrapper functions,
-*
-*(4) GPIOLIB=n, ALCHEMY_GPIO_INDIRECT=n:
-* inlinable gpio functions are provided which enable access to the
-* Au1300 gpios only by using the numbers straight out of the data-
-* sheets.
-
-* Cases 1 and 3 are intended for boards which want to provide their own
-* GPIO namespace and -operations (i.e. for example you have 8 GPIOs
-* which are in part provided by spare Au1300 GPIO pins and in part by
-* an external FPGA but you still want them to be accessible in linux
-* as gpio0-7. The board can of course use the alchemy_gpioX_* functions
-* as required).

- This kernel feature is useful for number crunching applications
- that may need to compute untrusted bytecode during their
- execution. By using pipes or other transports made available to
- the process as file descriptors supporting the read/write
- syscalls, it's possible to isolate those applications in
- their own address space using seccomp. Once seccomp is
- enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
- and the task is only allowed to execute a few safe syscalls
- defined by each seccomp mode.

- If unsure, say Y. Only embedded should say N here.

+ * To randomize kernel base address we have to consider several facts:
+ * 1. physical online memory might not be continuous and have holes. mem_detect
+ * info contains list of online memory ranges we should consider.
+ * 2. we have several memory regions which are occupied and we should not
+ * overlap and destroy them. Currently safe_addr tells us the border below
+ * which all those occupied regions are. We are safe to use anything above
+ * safe_addr.
+ * 3. the upper limit might apply as well, even if memory above that limit is
+ * online. Currently those limitations are:
+ * 3.1. Limit set by "mem=" kernel command line option
+ * 3.2. memory reserved at the end for kasan initialization.
+ * 4. kernel base address must be aligned to THREAD_SIZE (kernel stack size).
+ * Which is required for CONFIG_CHECK_STACK. Currently THREAD_SIZE is 4 pages
+ * (16 pages when the kernel is built with kasan enabled)
+ * Assumptions:
+ * 1. kernel size (including .bss size) and upper memory limit are page aligned.
+ * 2. mem_detect memory region start is THREAD_SIZE aligned / end is PAGE_SIZE
+ * aligned (in practice memory configurations granularity on z/VM and LPAR
+ * is 1mb).
+ *
+ * To guarantee uniform distribution of kernel base address among all suitable
+ * addresses we generate random value just once. For that we need to build a
+ * continuous range in which every value would be suitable. We can build this
+ * range by simply counting all suitable addresses (let's call them positions)
+ * which would be valid as kernel base address. To count positions we iterate
+ * over online memory ranges. For each range which is big enough for the
+ * kernel image we count all suitable addresses we can put the kernel image at
+ * that is
+ * (end - start - kernel_size) / THREAD_SIZE + 1
+ * Two functions count_valid_kernel_positions and position_to_address help
+ * to count positions in memory range given and then convert position back
+ * to address.

- * The SMP TLB coherency scheme we use works as follows:
- *
- * 1) mm->cpu_vm_mask is a bit mask of which cpus an address
- * space has (potentially) executed on, this is the heuristic
- * we use to avoid doing cross calls.
- *
- * Also, for flushing from kswapd and also for clones, we
- * use cpu_vm_mask as the list of cpus to make run the TLB.
- *
- * 2) TLB context numbers are shared globally across all processors
- * in the system, this allows us to play several games to avoid
- * cross calls.
- *
- * One invariant is that when a cpu switches to a process, and
- * that processes tsk->active_mm->cpu_vm_mask does not have the
- * current cpu's bit set, that tlb context is flushed locally.
- *
- * If the address space is non-shared (ie. mm->count == 1) we avoid
- * cross calls when we want to flush the currently running process's
- * tlb state. This is done by clearing all cpu bits except the current
- * processor's in current->mm->cpu_vm_mask and performing the
- * flush locally only. This will force any subsequent cpus which run
- * this task to flush the context from the local tlb if the process
- * migrates to another cpu (again).
- *
- * 3) For shared address spaces (threads) and swapping we bite the
- * bullet for most cases and perform the cross call (but only to
- * the cpus listed in cpu_vm_mask).
- *
- * The performance gain from "optimizing" away the cross call for threads is
- * questionable (in theory the big win for threads is the massive sharing of
- * address space state across processors).
+ * mm->cpu_vm_mask is a bit mask of which cpus an address
+ * space has (potentially) executed on, this is the heuristic

- * Failed to allocate space for phdrs

- * during the decompression stage.
- *
- * If the compressed x86 kernel is relocatable at run-time, it should be

+ * prevents the linker from trying to create unwanted run-time relocation
+ * entries for the reference when the compressed kernel is linked as PIE.
+ *
+ * A reference X(%reg) will result in the link-time VA of X being stored with

+ * adds the 64-bit base address where the kernel is loaded.
+ *
+ * Replacing it with (X-startup_32)(%reg) results in the offset being stored,
+ * and no run-time relocation.
+ *
+ * The macro should be used as a displacement with a base register containing
+ * the run-time address of startup_32 [i.e. rva(X)(%reg)], or as an immediate
+ * [$ rva(X)].
+ *
+ * This macro can only be used from within the .head.text section, since the

+ *
+ * #1 is mathematically simpler but has the drawback of requiring synchronous
+ * global hweight_inuse updates when idle iocg's get activated or inuse weights
+ * change due to donation snapbacks as it has the possibility of grossly
+ * overshooting what's allowed by the model and vrate.
+ *
+ * #2 is inherently safe with local operations. The donating iocg can easily
+ * snap back to higher weights when needed without worrying about impacts on
+ * other nodes as the impacts will be inherently correct. This also makes idle
+ * iocg activations safe. The only effect activations have is decreasing
+ * hweight_inuse of others, the right solution to which is for those iocgs to
+ * snap back to higher weights.
+ *
+ * So, we go with #2. The challenge is calculating how each donating iocg's
+ * inuse should be adjusted to achieve the target donation amounts. This is done
+ * using Andy's method described in the following pdf.
+ *
+ * https://drive.google.com/file/d/1PsJwxPFtjUnwOY1QJ5AeICCcsL7BM3bo
+ *
+ * Given the weights and target after-donation hweight_inuse values, Andy's
+ * method determines how the proportional distribution should look like at each
+ * sibling level to maintain the relative relationship between all non-donating
+ * pairs. To roughly summarize, it divides the tree into donating and
+ * non-donating parts, calculates global donation rate which is used to
+ * determine the target hweight_inuse for each node, and then derives per-level
+ * proportions.
+ *
+ * The following pdf shows that global distribution calculated this way can be
+ * achieved by scaling inuse weights of donating leaves and propagating the
+ * adjustments upwards proportionally.
+ *
+ * https://drive.google.com/file/d/1vONz1-fzVO7oY5DXXsLjSxEtYYQbOvsE
+ *
+ * Combining the above two, we can determine how each leaf iocg's inuse should
+ * be adjusted to achieve the target donation.

+ * This driver implements the regmap operations for a generic SPI
+ * master to access the registers of the spi slave chip which has an
+ * Avalone bus in it.
+ *
+ * The "SPI slave to Avalon Master Bridge" (spi-avmm) IP should be integrated
+ * in the spi slave chip. The IP acts as a bridge to convert encoded streams of
+ * bytes from the host to the internal register read/write on Avalon bus. In
+ * order to issue register access requests to the slave chip, the host should
+ * send formatted bytes that conform to the transfer protocol.
+ * The transfer protocol contains 3 layers: transaction layer, packet layer
+ * and physical layer.
+ *
+ * Reference Documents could be found at:
+ * https://www.intel.com/content/www/us/en/programmable/documentation/sfo1400787952932.html
+ *
+ * Chapter "SPI Slave/JTAG to Avalon Master Bridge Cores" is a general
+ * introduction to the protocol.
+ *
+ * Chapter "Avalon Packets to Transactions Converter Core" describes
+ * the transaction layer.
+ *
+ * Chapter "Avalon-ST Bytes to Packets and Packets to Bytes Converter Cores"
+ * describes the packet layer.
+ *
+ * Chapter "Avalon-ST Serial Peripheral Interface Core" describes the
+ * physical layer.
+ *
+ *
+ * When host issues a regmap read/write, the driver will transform the request
+ * to byte stream layer by layer. It formats the register addr, value and
+ * length to the transaction layer request, then converts the request to packet
+ * layer bytes stream and then to physical layer bytes stream. Finally the
+ * driver sends the formatted byte stream over SPI bus to the slave chip.
+ *
+ * The spi-avmm IP on the slave chip decodes the byte stream and initiates
+ * register read/write on its internal Avalon bus, and then encodes the
+ * response to byte stream and sends back to host.
+ *
+ * The driver receives the byte stream, reverses the 3 layers transformation,
+ * and finally gets the response value (read out data for register read,
+ * successful written size for register write).

+ * Time T2: passId = getPasId(vmid); vmid is associated with Pasid P2

+ * queue is slotted, OFF if there is no queue. A process could have ZERO or
+ * more queues slotted and submitting waves to be run on compute units. Even
+ * when there is a queue it is possible there could be zero wave fronts, this
+ * can happen when queue is waiting on top-of-pipe events - e.g. waitRegMem
+ * command
+ *
+ * For each bit that is ON from above:
+ *
+ * Read (SPI_CSQ_WF_ACTIVE_COUNT_0 + queue_idx) register. It provides the
+ * number of waves that are in flight for the queue at specified index. The

+-*- org -*-
+
+* On/off LEDs should have max_brightness of 1
+* Get rid of enum led_brightness
+
+It is really an integer, as maximum is configurable. Get rid of it, or
+make it into typedef or something.
+
+* Review atomicity requirements in LED subsystem
+
+Calls that may and that may not block are mixed in same structure, and
+semantics is sometimes non-intuitive. (For example blink callback may
+not sleep.) Review the requirements for any bugs and document them
+clearly.
+
+* LED names are still a mess
+
+No two LEDs have same name, so the names are probably unusable for the
+userland. Nudge authors into creating common LED names for common
+functionality.
+
+? Perhaps check for known LED names during boot, and warn if there are
+LEDs not on the list?
+
+* Split drivers into subdirectories
+
+The number of drivers is getting big, and driver for on/off LED on a
+i/o port is really quite different from camera flash LED, which is
+really different from driver for RGB color LED that can run its own
+microcode. Split the drivers somehow.
+
+* Figure out what to do with RGB leds
+
+Multicolor is a bit too abstract. Yes, we can have
+Green-Magenta-Ultraviolet LED, but so far all the LEDs we support are
+RGB, and not even RGB-White or RGB-Yellow variants emerged.
+
+Multicolor is not a good fit for RGB LED. It does not really know
+about LED color. In particular, there's no way to make LED "white".
+
+Userspace is interested in knowing "this LED can produce arbitrary
+color", which not all multicolor LEDs can.
+
+ Proposal: let's add "rgb" to led_colors in drivers/leds/led-core.c,
+ add corresponding device tree defines, and use that, instead of
+ multicolor for RGB LEDs.
+
+ We really need to do that now; "white" stuff can wait.
+
+RGB LEDs are quite common, and it would be good to be able to turn LED
+white and to turn it into any arbitrary color. It is essential that
+userspace is able to set arbitrary colors, and it might be good to
+have that ability from kernel, too... to allow full-color triggers.
+
+* Command line utility to manipulate the LEDs?
+
+/sys interface is not really suitable to use by hand, should we have
+an utility to perform LED control?
+
+In particular, LED names are still a mess (see above) and utility
+could help there by presenting both old and new names while we clean
+them up.
+
+In future, I'd like utility to accept both old and new names while we
+clean them up.
+
+It would be also nice to have useful listing mode -- name, type,
+current brightness/trigger...
+
+In future, it would be good to be able to set rgb led to particular
+color.
+
+And probably user-friendly interface to access LEDs for particular
+ethernet interface would be nice.
