+DMA_ATTR_NO_WARN
+----------------
+
+This tells the DMA-mapping subsystem to suppress allocation failure reports
+(similarly to __GFP_NOWARN).
+
+On some architectures allocation failures are reported with error messages
+to the system logs.  Although this can help to identify and debug problems,
+drivers which handle failures (eg, retry later) have no problems with them,
+and can actually flood the system logs with error messages that aren't any
+problem at all, depending on the implementation of the retry mechanism.
+
+So, this provides a way for drivers to avoid those error messages on calls
+where allocation failures are not a problem, and shouldn't bother the logs.

+Hisilicon RoCE DT description
+
+Hisilicon RoCE engine is a part of network subsystem.
+It works depending on other part of network wubsytem, such as, gmac and
+dsa fabric.
+
+Additional properties are described here:
+
+Required properties:
+- compatible: Should contain "hisilicon,hns-roce-v1".
+- reg: Physical base address of the RoCE driver and
+length of memory mapped region.
+- eth-handle: phandle, specifies a reference to a node
+representing a ethernet device.
+- dsaf-handle: phandle, specifies a reference to a node
+representing a dsaf device.
+- #address-cells: must be 2
+- #size-cells: must be 2
+Optional properties:
+- dma-coherent: Present if DMA operations are coherent.
+- interrupt-parent: the interrupt parent of this device.
+- interrupts: should contain 32 completion event irq,1 async event irq
+and 1 event overflow irq.
+- interrupt-names:should be one of 34 irqs for roce device
+  - hns-roce-comp-0 ~ hns-roce-comp-31: 32 complete event irq
+  - hns-roce-async: 1 async event irq
+  - hns-roce-common: named common exception warning irq

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

+================
+
+Optional properties
+-------------------
+
+- iommu-map: Maps a Requester ID to an IOMMU and associated iommu-specifier
+  data.
+
+  The property is an arbitrary number of tuples of
+  (rid-base,iommu,iommu-base,length).
+
+  Any RID r in the interval [rid-base, rid-base + length) is associated with
+  the listed IOMMU, with the iommu-specifier (r - rid-base + iommu-base).
+
+- iommu-map-mask: A mask to be applied to each Requester ID prior to being
+  mapped to an iommu-specifier per the iommu-map property.

 Mode Setting Helper Functions
 =============================
 
-The plane, CRTC, encoder and connector functions provided by the drivers
-implement the DRM API. They're called by the DRM core and ioctl handlers
-to handle device state changes and configuration request. As
-implementing those functions often requires logic not specific to
-drivers, mid-layer helper functions are available to avoid duplicating
-boilerplate code.
-
-The DRM core contains one mid-layer implementation. The mid-layer
-provides implementations of several plane, CRTC, encoder and connector
-functions (called from the top of the mid-layer) that pre-process
-requests and call lower-level functions provided by the driver (at the
-bottom of the mid-layer). For instance, the
-:c:func:`drm_crtc_helper_set_config()` function can be used to
-fill the :c:type:`struct drm_crtc_funcs <drm_crtc_funcs>`
-set_config field. When called, it will split the set_config operation
-in smaller, simpler operations and call the driver to handle them.
-
-To use the mid-layer, drivers call
-:c:func:`drm_crtc_helper_add()`,
-:c:func:`drm_encoder_helper_add()` and
-:c:func:`drm_connector_helper_add()` functions to install their
-mid-layer bottom operations handlers, and fill the :c:type:`struct
-drm_crtc_funcs <drm_crtc_funcs>`, :c:type:`struct
-drm_encoder_funcs <drm_encoder_funcs>` and :c:type:`struct
-drm_connector_funcs <drm_connector_funcs>` structures with
-pointers to the mid-layer top API functions. Installing the mid-layer
-bottom operation handlers is best done right after registering the
-corresponding KMS object.
-
-The mid-layer is not split between CRTC, encoder and connector
-operations. To use it, a driver must provide bottom functions for all of
-the three KMS entities.
+The DRM subsystem aims for a strong separation between core code and helper
+libraries. Core code takes care of general setup and teardown and decoding
+userspace requests to kernel internal objects. Everything else is handled by a
+large set of helper libraries, which can be combined freely to pick and choose
+for each driver what fits, and avoid shared code where special behaviour is
+needed.
+
+This distinction between core code and helpers is especially strong in the
+modesetting code, where there's a shared userspace ABI for all drivers. This is
+in contrast to the render side, where pretty much everything (with very few
+exceptions) can be considered optional helper code.
+
+There are a few areas these helpers can grouped into:
+
+* Helpers to implement modesetting. The important ones here are the atomic
+  helpers. Old drivers still often use the legacy CRTC helpers. They both share
+  the same set of common helper vtables. For really simple drivers (anything
+  that would have been a great fit in the deprecated fbdev subsystem) there's
+  also the simple display pipe helpers.
+
+* There's a big pile of helpers for handling outputs. First the generic bridge
+  helpers for handling encoder and transcoder IP blocks. Second the panel helpers
+  for handling panel-related information and logic. Plus then a big set of
+  helpers for the various sink standards (DisplayPort, HDMI, MIPI DSI). Finally
+  there's also generic helpers for handling output probing, and for dealing with
+  EDIDs.
+
+* The last group of helpers concerns itself with the frontend side of a display
+  pipeline: Planes, handling rectangles for visibility checking and scissoring,
+  flip queues and assorted bits.

 Frame Buffer Abstraction
-------------------------
-
-Frame buffers are abstract memory objects that provide a source of
-pixels to scanout to a CRTC. Applications explicitly request the
-creation of frame buffers through the DRM_IOCTL_MODE_ADDFB(2) ioctls
-and receive an opaque handle that can be passed to the KMS CRTC control,
-plane configuration and page flip functions.
-
-Frame buffers rely on the underneath memory manager for low-level memory
-operations. When creating a frame buffer applications pass a memory
-handle (or a list of memory handles for multi-planar formats) through
-the ``drm_mode_fb_cmd2`` argument. For drivers using GEM as their
-userspace buffer management interface this would be a GEM handle.
-Drivers are however free to use their own backing storage object
-handles, e.g. vmwgfx directly exposes special TTM handles to userspace
-and so expects TTM handles in the create ioctl and not GEM handles.
-
-The lifetime of a drm framebuffer is controlled with a reference count,
-drivers can grab additional references with
-:c:func:`drm_framebuffer_reference()`and drop them again with
-:c:func:`drm_framebuffer_unreference()`. For driver-private
-framebuffers for which the last reference is never dropped (e.g. for the
-fbdev framebuffer when the struct :c:type:`struct drm_framebuffer
-<drm_framebuffer>` is embedded into the fbdev helper struct)
-drivers can manually clean up a framebuffer at module unload time with
-:c:func:`drm_framebuffer_unregister_private()`.

-Planes (:c:type:`struct drm_plane <drm_plane>`)
------------------------------------------------
-
-A plane represents an image source that can be blended with or overlayed
-on top of a CRTC during the scanout process. Planes are associated with
-a frame buffer to crop a portion of the image memory (source) and
-optionally scale it to a destination size. The result is then blended
-with or overlayed on top of a CRTC.
-
-The DRM core recognizes three types of planes:
-
--  DRM_PLANE_TYPE_PRIMARY represents a "main" plane for a CRTC.
-   Primary planes are the planes operated upon by CRTC modesetting and
-   flipping operations described in the page_flip hook in
-   :c:type:`struct drm_crtc_funcs <drm_crtc_funcs>`.
--  DRM_PLANE_TYPE_CURSOR represents a "cursor" plane for a CRTC.
-   Cursor planes are the planes operated upon by the
-   DRM_IOCTL_MODE_CURSOR and DRM_IOCTL_MODE_CURSOR2 ioctls.
--  DRM_PLANE_TYPE_OVERLAY represents all non-primary, non-cursor
-   planes. Some drivers refer to these types of planes as "sprites"
-   internally.
-
-For compatibility with legacy userspace, only overlay planes are made
-available to userspace by default. Userspace clients may set the
-DRM_CLIENT_CAP_UNIVERSAL_PLANES client capability bit to indicate
-that they wish to receive a universal plane list containing all plane
-types.
-
-Plane Initialization
-~~~~~~~~~~~~~~~~~~~~
-
-To create a plane, a KMS drivers allocates and zeroes an instances of
-:c:type:`struct drm_plane <drm_plane>` (possibly as part of a
-larger structure) and registers it with a call to
-:c:func:`drm_universal_plane_init()`. The function takes a
-bitmask of the CRTCs that can be associated with the plane, a pointer to
-the plane functions, a list of format supported formats, and the type of
-plane (primary, cursor, or overlay) being initialized.
-
-Cursor and overlay planes are optional. All drivers should provide one
-primary plane per CRTC (although this requirement may change in the
-future); drivers that do not wish to provide special handling for
-primary planes may make use of the helper functions described in ? to
-create and register a primary plane with standard capabilities.
-
-Encoders (:c:type:`struct drm_encoder <drm_encoder>`)
------------------------------------------------------
-
-An encoder takes pixel data from a CRTC and converts it to a format
-suitable for any attached connectors. On some devices, it may be
-possible to have a CRTC send data to more than one encoder. In that
-case, both encoders would receive data from the same scanout buffer,
-resulting in a "cloned" display configuration across the connectors
-attached to each encoder.
-
-Encoder Initialization
-~~~~~~~~~~~~~~~~~~~~~~
-
-As for CRTCs, a KMS driver must create, initialize and register at least
-one :c:type:`struct drm_encoder <drm_encoder>` instance. The
-instance is allocated and zeroed by the driver, possibly as part of a
-larger structure.
-
-Drivers must initialize the :c:type:`struct drm_encoder
-<drm_encoder>` possible_crtcs and possible_clones fields before
-registering the encoder. Both fields are bitmasks of respectively the
-CRTCs that the encoder can be connected to, and sibling encoders
-candidate for cloning.
-
-After being initialized, the encoder must be registered with a call to
-:c:func:`drm_encoder_init()`. The function takes a pointer to the
-encoder functions and an encoder type. Supported types are
-
--  DRM_MODE_ENCODER_DAC for VGA and analog on DVI-I/DVI-A
--  DRM_MODE_ENCODER_TMDS for DVI, HDMI and (embedded) DisplayPort
--  DRM_MODE_ENCODER_LVDS for display panels
--  DRM_MODE_ENCODER_TVDAC for TV output (Composite, S-Video,
-   Component, SCART)
--  DRM_MODE_ENCODER_VIRTUAL for virtual machine displays
-
-Encoders must be attached to a CRTC to be used. DRM drivers leave
-encoders unattached at initialization time. Applications (or the fbdev
-compatibility layer when implemented) are responsible for attaching the
-encoders they want to use to a CRTC.
-
-Connectors (:c:type:`struct drm_connector <drm_connector>`)
------------------------------------------------------------
-
-A connector is the final destination for pixel data on a device, and
-usually connects directly to an external display device like a monitor
-or laptop panel. A connector can only be attached to one encoder at a
-time. The connector is also the structure where information about the
-attached display is kept, so it contains fields for display data, EDID
-data, DPMS & connection status, and information about modes supported on
-the attached displays.
-
-Connector Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Finally a KMS driver must create, initialize, register and attach at
-least one :c:type:`struct drm_connector <drm_connector>`
-instance. The instance is created as other KMS objects and initialized
-by setting the following fields.
-
-interlace_allowed
-    Whether the connector can handle interlaced modes.
-
-doublescan_allowed
-    Whether the connector can handle doublescan.
-
-display_info
-    Display information is filled from EDID information when a display
-    is detected. For non hot-pluggable displays such as flat panels in
-    embedded systems, the driver should initialize the
-    display_info.width_mm and display_info.height_mm fields with the
-    physical size of the display.
-
-polled
-    Connector polling mode, a combination of
-
-    DRM_CONNECTOR_POLL_HPD
-        The connector generates hotplug events and doesn't need to be
-        periodically polled. The CONNECT and DISCONNECT flags must not
-        be set together with the HPD flag.
-
-    DRM_CONNECTOR_POLL_CONNECT
-        Periodically poll the connector for connection.
-
-    DRM_CONNECTOR_POLL_DISCONNECT
-        Periodically poll the connector for disconnection.
-
-    Set to 0 for connectors that don't support connection status
-    discovery.
-
-The connector is then registered with a call to
-:c:func:`drm_connector_init()` with a pointer to the connector
-functions and a connector type, and exposed through sysfs with a call to
-:c:func:`drm_connector_register()`.
-
-Supported connector types are

-Modes
-'''''
-
-int (\*fill_modes)(struct drm_connector \*connector, uint32_t

-Fill the mode list with all supported modes for the connector. If the

-than ``max_height``.
-
-The connector must also fill in this operation its display_info
-width_mm and height_mm fields with the connected display physical size
-in millimeters. The fields should be set to 0 if the value isn't known
-or is not applicable (for instance for projector devices).
-
-Connection Status

-
-The connection status is updated through polling or hotplug events when

 KMS Properties
 ==============
 
-Drivers may need to expose additional parameters to applications than
-those described in the previous sections. KMS supports attaching
-properties to CRTCs, connectors and planes and offers a userspace API to
-list, get and set the property values.
-
-Properties are identified by a name that uniquely defines the property
-purpose, and store an associated value. For all property types except
-blob properties the value is a 64-bit unsigned integer.
-
-KMS differentiates between properties and property instances. Drivers
-first create properties and then create and associate individual
-instances of those properties to objects. A property can be instantiated
-multiple times and associated with different objects. Values are stored
-in property instances, and all other property information are stored in
-the property and shared between all instances of the property.
-
-Every property is created with a type that influences how the KMS core
-handles the property. Supported property types are
-
-DRM_MODE_PROP_RANGE
-    Range properties report their minimum and maximum admissible values.
-    The KMS core verifies that values set by application fit in that
-    range.
-
-DRM_MODE_PROP_ENUM
-    Enumerated properties take a numerical value that ranges from 0 to
-    the number of enumerated values defined by the property minus one,
-    and associate a free-formed string name to each value. Applications
-    can retrieve the list of defined value-name pairs and use the
-    numerical value to get and set property instance values.
-
-DRM_MODE_PROP_BITMASK
-    Bitmask properties are enumeration properties that additionally
-    restrict all enumerated values to the 0..63 range. Bitmask property
-    instance values combine one or more of the enumerated bits defined
-    by the property.
-
-DRM_MODE_PROP_BLOB
-    Blob properties store a binary blob without any format restriction.
-    The binary blobs are created as KMS standalone objects, and blob
-    property instance values store the ID of their associated blob
-    object.
-
-    Blob properties are only used for the connector EDID property and
-    cannot be created by drivers.
-
-To create a property drivers call one of the following functions
-depending on the property type. All property creation functions take
-property flags and name, as well as type-specific arguments.
-
--  struct drm_property \*drm_property_create_range(struct
-   drm_device \*dev, int flags, const char \*name, uint64_t min,
-   uint64_t max);
-   Create a range property with the given minimum and maximum values.
-
--  struct drm_property \*drm_property_create_enum(struct drm_device
-   \*dev, int flags, const char \*name, const struct
-   drm_prop_enum_list \*props, int num_values);
-   Create an enumerated property. The ``props`` argument points to an
-   array of ``num_values`` value-name pairs.
-
--  struct drm_property \*drm_property_create_bitmask(struct
-   drm_device \*dev, int flags, const char \*name, const struct
-   drm_prop_enum_list \*props, int num_values);
-   Create a bitmask property. The ``props`` argument points to an array
-   of ``num_values`` value-name pairs.
-
-Properties can additionally be created as immutable, in which case they
-will be read-only for applications but can be modified by the driver. To
-create an immutable property drivers must set the
-DRM_MODE_PROP_IMMUTABLE flag at property creation time.
-
-When no array of value-name pairs is readily available at property
-creation time for enumerated or range properties, drivers can create the
-property using the :c:func:`drm_property_create()` function and
-manually add enumeration value-name pairs by calling the
-:c:func:`drm_property_add_enum()` function. Care must be taken to
-properly specify the property type through the ``flags`` argument.
-
-After creating properties drivers can attach property instances to CRTC,
-connector and plane objects by calling the
-:c:func:`drm_object_attach_property()`. The function takes a
-pointer to the target object, a pointer to the previously created
-property and an initial instance value.

+Open-Source Userspace Requirements
+==================================
+
+The DRM subsystem has stricter requirements than most other kernel subsystems on
+what the userspace side for new uAPI needs to look like. This section here
+explains what exactly those requirements are, and why they exist.
+
+The short summary is that any addition of DRM uAPI requires corresponding
+open-sourced userspace patches, and those patches must be reviewed and ready for
+merging into a suitable and canonical upstream project.
+
+GFX devices (both display and render/GPU side) are really complex bits of
+hardware, with userspace and kernel by necessity having to work together really
+closely.  The interfaces, for rendering and modesetting, must be extremely wide
+and flexible, and therefore it is almost always impossible to precisely define
+them for every possible corner case. This in turn makes it really practically
+infeasible to differentiate between behaviour that's required by userspace, and
+which must not be changed to avoid regressions, and behaviour which is only an
+accidental artifact of the current implementation.
+
+Without access to the full source code of all userspace users that means it
+becomes impossible to change the implementation details, since userspace could
+depend upon the accidental behaviour of the current implementation in minute
+details. And debugging such regressions without access to source code is pretty
+much impossible. As a consequence this means:
+
+- The Linux kernel's "no regression" policy holds in practice only for
+  open-source userspace of the DRM subsystem. DRM developers are perfectly fine
+  if closed-source blob drivers in userspace use the same uAPI as the open
+  drivers, but they must do so in the exact same way as the open drivers.
+  Creative (ab)use of the interfaces will, and in the past routinely has, lead
+  to breakage.
+
+- Any new userspace interface must have an open-source implementation as
+  demonstration vehicle.
+
+The other reason for requiring open-source userspace is uAPI review. Since the
+kernel and userspace parts of a GFX stack must work together so closely, code
+review can only assess whether a new interface achieves its goals by looking at
+both sides. Making sure that the interface indeed covers the use-case fully
+leads to a few additional requirements:
+
+- The open-source userspace must not be a toy/test application, but the real
+  thing. Specifically it needs to handle all the usual error and corner cases.
+  These are often the places where new uAPI falls apart and hence essential to
+  assess the fitness of a proposed interface.
+
+- The userspace side must be fully reviewed and tested to the standards of that
+  userspace project. For e.g. mesa this means piglit testcases and review on the
+  mailing list. This is again to ensure that the new interface actually gets the
+  job done.
+
+- The userspace patches must be against the canonical upstream, not some vendor
+  fork. This is to make sure that no one cheats on the review and testing
+  requirements by doing a quick fork.
+
+- The kernel patch can only be merged after all the above requirements are met,
+  but it **must** be merged **before** the userspace patches land. uAPI always flows
+  from the kernel, doing things the other way round risks divergence of the uAPI
+  definitions and header files.
+
+These are fairly steep requirements, but have grown out from years of shared
+pain and experience with uAPI added hastily, and almost always regretted about
+just as fast. GFX devices change really fast, requiring a paradigm shift and
+entire new set of uAPI interfaces every few years at least. Together with the
+Linux kernel's guarantee to keep existing userspace running for 10+ years this
+is already rather painful for the DRM subsystem, with multiple different uAPIs
+for the same thing co-existing. If we add a few more complete mistakes into the
+mix every year it would be entirely unmanageable.

-
-       -  The buffer resides in device memory and has been mapped into the
-	  application's address space, see :ref:`mmap` for details.
-	  Drivers set or clear this flag when the
-	  :ref:`VIDIOC_QUERYBUF`,
-	  :ref:`VIDIOC_QBUF` or

-
-       -  ``V4L2_BUF_FLAG_QUEUED``
-
-       -  0x00000002
-
-       -  Internally drivers maintain two buffer queues, an incoming and
-	  outgoing queue. When this flag is set, the buffer is currently on
-	  the incoming queue. It automatically moves to the outgoing queue
-	  after the buffer has been filled (capture devices) or displayed
-	  (output devices). Drivers set or clear this flag when the
-	  ``VIDIOC_QUERYBUF`` ioctl is called. After (successful) calling
-	  the ``VIDIOC_QBUF``\ ioctl it is always set and after
-	  ``VIDIOC_DQBUF`` always cleared.
-

-
-       -  ``V4L2_BUF_FLAG_DONE``
-
-       -  0x00000004
-
-       -  When this flag is set, the buffer is currently on the outgoing
-	  queue, ready to be dequeued from the driver. Drivers set or clear
-	  this flag when the ``VIDIOC_QUERYBUF`` ioctl is called. After
-	  calling the ``VIDIOC_QBUF`` or ``VIDIOC_DQBUF`` it is always
-	  cleared. Of course a buffer cannot be on both queues at the same
-	  time, the ``V4L2_BUF_FLAG_QUEUED`` and ``V4L2_BUF_FLAG_DONE`` flag
-	  are mutually exclusive. They can be both cleared however, then the
-	  buffer is in "dequeued" state, in the application domain so to

-
-       -  ``V4L2_BUF_FLAG_ERROR``
-
-       -  0x00000040
-
-       -  When this flag is set, the buffer has been dequeued successfully,
-	  although the data might have been corrupted. This is recoverable,
-	  streaming may continue as normal and the buffer may be reused
-	  normally. Drivers set this flag when the ``VIDIOC_DQBUF`` ioctl is

-
-       -  ``V4L2_BUF_FLAG_KEYFRAME``
-
-       -  0x00000008
-
-       -  Drivers set or clear this flag when calling the ``VIDIOC_DQBUF``
-	  ioctl. It may be set by video capture devices when the buffer
-	  contains a compressed image which is a key frame (or field), i. e.
-	  can be decompressed on its own. Also known as an I-frame.

-
-       -  Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags predicted frames

-
-       -  ``V4L2_BUF_FLAG_BFRAME``
-
-       -  0x00000020
-
-       -  Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags a bi-directional
-	  predicted frame or field which contains only the differences

-
-       -  ``V4L2_BUF_FLAG_TIMECODE``
-
-       -  0x00000100
-
-       -  The ``timecode`` field is valid. Drivers set or clear this flag

-
-       -  Caches do not have to be invalidated for this buffer. Typically

-
-    -  .. _`V4L2-BUF-FLAG-NO-CACHE-CLEAN`:
-
-       -  ``V4L2_BUF_FLAG_NO_CACHE_CLEAN``
-

-
-       -  Caches do not have to be cleaned for this buffer. Typically

-	  DMA-capable unit, in which case caches have not been used.
-
-    -  .. _`V4L2-BUF-FLAG-LAST`:
-
-       -  ``V4L2_BUF_FLAG_LAST``
-
-       -  0x00100000
-
-       -  Last buffer produced by the hardware. mem2mem codec drivers set
-	  this flag on the capture queue for the last buffer when the
-	  :ref:`VIDIOC_QUERYBUF` or
-	  :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Due to
-	  hardware limitations, the last buffer may be empty. In this case
-	  the driver will set the ``bytesused`` field to 0, regardless of
-	  the format. Any Any subsequent call to the
-	  :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl will not block anymore,
-	  but return an ``EPIPE`` error code.

-
-       -  ``V4L2_BUF_FLAG_TIMESTAMP_UNKNOWN``
-

-
-       -  Unknown timestamp type. This type is used by drivers before Linux
-	  3.9 and may be either monotonic (see below) or realtime (wall
-	  clock). Monotonic clock has been favoured in embedded systems
-	  whereas most of the drivers use the realtime clock. Either kinds
-	  of timestamps are available in user space via
-	  :c:func:`clock_gettime(2)` using clock IDs ``CLOCK_MONOTONIC``
-	  and ``CLOCK_REALTIME``, respectively.
-
-    -  .. _`V4L2-BUF-FLAG-TIMESTAMP-MONOTONIC`:

-       -  ``V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC``
-
-       -  0x00002000
-
-       -  The buffer timestamp has been taken from the ``CLOCK_MONOTONIC``

+
+      - ``V4L2_BUF_FLAG_MAPPED``
+      - 0x00000001
+      - The buffer resides in device memory and has been mapped into the
+	application's address space, see :ref:`mmap` for details.
+	Drivers set or clear this flag when the
+	:ref:`VIDIOC_QUERYBUF`,
+	:ref:`VIDIOC_QBUF` or
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Set by the
+	driver.

+
+      - ``V4L2_BUF_FLAG_QUEUED``
+      - 0x00000002
+      - Internally drivers maintain two buffer queues, an incoming and
+	outgoing queue. When this flag is set, the buffer is currently on
+	the incoming queue. It automatically moves to the outgoing queue
+	after the buffer has been filled (capture devices) or displayed
+	(output devices). Drivers set or clear this flag when the
+	``VIDIOC_QUERYBUF`` ioctl is called. After (successful) calling
+	the ``VIDIOC_QBUF``\ ioctl it is always set and after
+	``VIDIOC_DQBUF`` always cleared.

+	this flag when the ``VIDIOC_QUERYBUF`` ioctl is called. After
+	calling the ``VIDIOC_QBUF`` or ``VIDIOC_DQBUF`` it is always
+	cleared. Of course a buffer cannot be on both queues at the same
+	time, the ``V4L2_BUF_FLAG_QUEUED`` and ``V4L2_BUF_FLAG_DONE`` flag
+	are mutually exclusive. They can be both cleared however, then the
+	buffer is in "dequeued" state, in the application domain so to

+
+      - ``V4L2_BUF_FLAG_ERROR``
+      - 0x00000040
+      - When this flag is set, the buffer has been dequeued successfully,
+	although the data might have been corrupted. This is recoverable,
+	streaming may continue as normal and the buffer may be reused
+	normally. Drivers set this flag when the ``VIDIOC_DQBUF`` ioctl is

+
+      - ``V4L2_BUF_FLAG_KEYFRAME``
+      - 0x00000008
+      - Drivers set or clear this flag when calling the ``VIDIOC_DQBUF``
+	ioctl. It may be set by video capture devices when the buffer
+	contains a compressed image which is a key frame (or field), i. e.
+	can be decompressed on its own. Also known as an I-frame.
+	Applications can set this bit when ``type`` refers to an output
+	stream.

+
+      - ``V4L2_BUF_FLAG_PFRAME``
+      - 0x00000010
+      - Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags predicted frames
+	or fields which contain only differences to a previous key frame.
+	Applications can set this bit when ``type`` refers to an output

+
+      - ``V4L2_BUF_FLAG_BFRAME``
+      - 0x00000020
+      - Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags a bi-directional
+	predicted frame or field which contains only the differences
+	between the current frame and both the preceding and following key
+	frames to specify its content. Applications can set this bit when
+	``type`` refers to an output stream.
+    * .. _`V4L2-BUF-FLAG-TIMECODE`:
+
+      - ``V4L2_BUF_FLAG_TIMECODE``
+      - 0x00000100
+      - The ``timecode`` field is valid. Drivers set or clear this flag
+	when the ``VIDIOC_DQBUF`` ioctl is called. Applications can set
+	this bit and the corresponding ``timecode`` structure when
+	``type`` refers to an output stream.
+    * .. _`V4L2-BUF-FLAG-PREPARED`:
+
+      - ``V4L2_BUF_FLAG_PREPARED``
+      - 0x00000400
+      - The buffer has been prepared for I/O and can be queued by the
+	application. Drivers set or clear this flag when the
+	:ref:`VIDIOC_QUERYBUF`,
+	:ref:`VIDIOC_PREPARE_BUF <VIDIOC_QBUF>`,
+	:ref:`VIDIOC_QBUF` or
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called.
+    * .. _`V4L2-BUF-FLAG-NO-CACHE-INVALIDATE`:
+
+      - ``V4L2_BUF_FLAG_NO_CACHE_INVALIDATE``
+      - 0x00000800
+      - Caches do not have to be invalidated for this buffer. Typically
+	applications shall use this flag if the data captured in the
+	buffer is not going to be touched by the CPU, instead the buffer
+	will, probably, be passed on to a DMA-capable hardware unit for
+	further processing or output.
+    * .. _`V4L2-BUF-FLAG-NO-CACHE-CLEAN`:
+
+      - ``V4L2_BUF_FLAG_NO_CACHE_CLEAN``
+      - 0x00001000
+      - Caches do not have to be cleaned for this buffer. Typically
+	applications shall use this flag for output buffers if the data in
+	this buffer has not been created by the CPU but by some
+	DMA-capable unit, in which case caches have not been used.
+    * .. _`V4L2-BUF-FLAG-LAST`:
+
+      - ``V4L2_BUF_FLAG_LAST``
+      - 0x00100000
+      - Last buffer produced by the hardware. mem2mem codec drivers set
+	this flag on the capture queue for the last buffer when the
+	:ref:`VIDIOC_QUERYBUF` or
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Due to
+	hardware limitations, the last buffer may be empty. In this case
+	the driver will set the ``bytesused`` field to 0, regardless of
+	the format. Any Any subsequent call to the
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl will not block anymore,
+	but return an ``EPIPE`` error code.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-MASK`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_MASK``
+      - 0x0000e000
+      - Mask for timestamp types below. To test the timestamp type, mask
+	out bits not belonging to timestamp type by performing a logical
+	and operation with buffer flags and timestamp mask.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-UNKNOWN`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_UNKNOWN``
+      - 0x00000000
+      - Unknown timestamp type. This type is used by drivers before Linux
+	3.9 and may be either monotonic (see below) or realtime (wall
+	clock). Monotonic clock has been favoured in embedded systems
+	whereas most of the drivers use the realtime clock. Either kinds
+	of timestamps are available in user space via
+	:c:func:`clock_gettime` using clock IDs ``CLOCK_MONOTONIC``
+	and ``CLOCK_REALTIME``, respectively.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-MONOTONIC`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC``
+      - 0x00002000
+      - The buffer timestamp has been taken from the ``CLOCK_MONOTONIC``
+	clock. To access the same clock outside V4L2, use
+	:c:func:`clock_gettime`.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-COPY`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_COPY``
+      - 0x00004000
+      - The CAPTURE buffer timestamp has been taken from the corresponding
+	OUTPUT buffer. This flag applies only to mem2mem devices.
+    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-MASK`:
+
+      - ``V4L2_BUF_FLAG_TSTAMP_SRC_MASK``
+      - 0x00070000
+      - Mask for timestamp sources below. The timestamp source defines the

+
+      - ``V4L2_BUF_FLAG_TSTAMP_SRC_EOF``
+      - 0x00000000

+
+Touch devices are accessed through character device special files named
+``/dev/v4l-touch0`` to ``/dev/v4l-touch255`` with major number 81 and
+dynamically allocated minor numbers 0 to 255.
+
+Overview
+========
+
+Sensors may be Optical, or Projected Capacitive touch (PCT).
+
+Processing is required to analyse the raw data and produce input events. In
+some systems, this may be performed on the ASIC and the raw data is purely a
+side-channel for diagnostics or tuning. In other systems, the ASIC is a simple
+analogue front end device which delivers touch data at high rate, and any touch
+processing must be done on the host.
+
+For capacitive touch sensing, the touchscreen is composed of an array of
+horizontal and vertical conductors (alternatively called rows/columns, X/Y
+lines, or tx/rx). Mutual Capacitance measured is at the nodes where the
+conductors cross. Alternatively, Self Capacitance measures the signal from each
+column and row independently.
+
+A touch input may be determined by comparing the raw capacitance measurement to
+a no-touch reference (or "baseline") measurement:
+
+Delta = Raw - Reference
+
+The reference measurement takes account of variations in the capacitance across
+the touch sensor matrix, for example manufacturing irregularities,
+environmental or edge effects.
+
+Querying Capabilities
+=====================
+
+Devices supporting the touch interface set the ``V4L2_CAP_VIDEO_CAPTURE`` flag
+and the ``V4L2_CAP_TOUCH`` flag in the ``capabilities`` field of
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl.
+
+At least one of the read/write or streaming I/O methods must be
+supported.
+
+The formats supported by touch devices are documented in
+:ref:`Touch Formats <tch-formats>`.
+
+Data Format Negotiation
+=======================
+
+A touch device may support any I/O method.

-
-       -  Two-planar format used by Samsung S5C73MX cameras. The first plane
-	  contains interleaved JPEG and UYVY image data, followed by meta
-	  data in form of an array of offsets to the UYVY data blocks. The
-	  actual pointer array follows immediately the interleaved JPEG/UYVY
-	  data, the number of entries in this array equals the height of the
-	  UYVY image. Each entry is a 4-byte unsigned integer in big endian
-	  order and it's an offset to a single pixel line of the UYVY image.
-	  The first plane can start either with JPEG or UYVY data chunk. The
-	  size of a single UYVY block equals the UYVY image's width
-	  multiplied by 2. The size of a JPEG chunk depends on the image and
-	  can vary with each line.
-
-	  The second plane, at an offset of 4084 bytes, contains a 4-byte
-	  offset to the pointer array in the first plane. This offset is
-	  followed by a 4-byte value indicating size of the pointer array.
-	  All numbers in the second plane are also in big endian order.
-	  Remaining data in the second plane is undefined. The information
-	  in the second plane allows to easily find location of the pointer
-	  array, which can be different for each frame. The size of the
-	  pointer array is constant for given UYVY image height.
-
-	  In order to extract UYVY and JPEG frames an application can
-	  initially set a data pointer to the start of first plane and then
-	  add an offset from the first entry of the pointers table. Such a
-	  pointer indicates start of an UYVY image pixel line. Whole UYVY
-	  line can be copied to a separate buffer. These steps should be
-	  repeated for each line, i.e. the number of entries in the pointer
-	  array. Anything what's in between the UYVY lines is JPEG data and
-	  should be concatenated to form the JPEG stream.

 Description
 ===========
 
-This is commonly the native format of digital cameras, reflecting the
-arrangement of sensors on the CCD device. Only one red, green or blue
-value is given for each pixel. Missing components must be interpolated
-from neighbouring pixels. From left to right the first row consists of a
-red and green value, the second row of a green and blue value. This
-scheme repeats to the right and down for every two columns and rows.
+These four pixel formats are raw sRGB / Bayer formats with 8 bits per
+sample. Each sample is stored in a byte. Each n-pixel row contains n/2
+green samples and n/2 blue or red samples, with alternating red and
+blue rows. They are conventionally described as GRGR... BGBG...,
+RGRG... GBGB..., etc. Below is an example of one of these formats:

+      - 4
+      - Triggered immediately when the reception of a frame has begun.
+	This event has a struct
+	:c:type:`v4l2_event_frame_sync`
+	associated with it.
+
+	If the hardware needs to be stopped in the case of a buffer
+	underrun it might not be able to generate this event. In such
+	cases the ``frame_sequence`` field in struct
+	:c:type:`v4l2_event_frame_sync` will not
+	be incremented. This causes two consecutive frame sequence numbers
+	to have n times frame interval in between them.
+    * - ``V4L2_EVENT_SOURCE_CHANGE``
+      - 5
+      - This event is triggered when a source parameter change is detected
+	during runtime by the video device. It can be a runtime resolution
+	change triggered by a video decoder or the format change happening
+	on an input connector. This event requires that the ``id`` matches
+	the input index (when used with a video device node) or the pad
+	index (when used with a subdevice node) from which you want to
+	receive events.
+
+	This event has a struct
+	:c:type:`v4l2_event_src_change`
+	associated with it. The ``changes`` bitfield denotes what has
+	changed for the subscribed pad. If multiple events occurred before
+	application could dequeue them, then the changes will have the
+	ORed value of all the events generated.
+    * - ``V4L2_EVENT_MOTION_DET``
+      - 6
+      - Triggered whenever the motion detection state for one or more of
+	the regions changes. This event has a struct
+	:c:type:`v4l2_event_motion_det`
+	associated with it.
+    * - ``V4L2_EVENT_PRIVATE_START``
+      - 0x08000000
+      - Base event number for driver-private events.

-
-	  Before controls are read from/written to hardware a validation

-	  checks might require hardware access for some devices, thus making
-	  it impossible to do those checks up-front. However, drivers should
-	  make a best-effort to do as many up-front checks as possible.
-
-	  This check is done to avoid leaving the hardware in an
-	  inconsistent state due to easy-to-avoid problems. But it leads to
-	  another problem: the application needs to know whether an error
-	  came from the validation step (meaning that the hardware was not
-	  touched) or from an error during the actual reading from/writing
-	  to hardware.
-
-	  The, in hindsight quite poor, solution for that is to set
-	  ``error_idx`` to ``count`` if the validation failed. This has the
-	  unfortunate side-effect that it is not possible to see which
-	  control failed the validation. If the validation was successful
-	  and the error happened while accessing the hardware, then

 All V4L2 devices support the ``VIDIOC_QUERYCAP`` ioctl. It is used to
 identify kernel devices compatible with this specification and to obtain
 information about driver and hardware capabilities. The ioctl takes a
-pointer to a struct :ref:`v4l2_capability <v4l2-capability>` which is
+pointer to a struct :c:type:`v4l2_capability` which is
 filled by the driver. When the driver is not compatible with this
 specification the ioctl returns an ``EINVAL`` error code.

+Receiving Sync Files from Userspace
+-----------------------------------
+
+When userspace needs to send an in-fence to the driver it passes file descriptor
+of the Sync File to the kernel. The kernel can then retrieve the fences
+from it.
+
+Interface:
+	struct fence *sync_file_get_fence(int fd);

+
+The returned reference is owned by the caller and must be disposed of
+afterwards using fence_put(). In case of error, a NULL is returned instead.

 permissions are enforced on data access only and have no effect on
 instruction fetches.
 
-=========================== Config Option ===========================
+=========================== Syscalls ===========================
 
-This config option adds approximately 1.5kb of text. and 50 bytes of
-data to the executable.  A workload which does large O_DIRECT reads
-of holes in XFS files was run to exercise get_user_pages_fast().  No
-performance delta was observed with the config option
-enabled or disabled.
+There are 3 system calls which directly interact with pkeys:
+
+	int pkey_alloc(unsigned long flags, unsigned long init_access_rights)
+	int pkey_free(int pkey);
+	int pkey_mprotect(unsigned long start, size_t len,
+			  unsigned long prot, int pkey);
+
+Before a pkey can be used, it must first be allocated with
+pkey_alloc().  An application calls the WRPKRU instruction
+directly in order to change access permissions to memory covered
+with a key.  In this example WRPKRU is wrapped by a C function
+called pkey_set().
+
+	int real_prot = PROT_READ|PROT_WRITE;
+	pkey = pkey_alloc(0, PKEY_DENY_WRITE);
+	ptr = mmap(NULL, PAGE_SIZE, PROT_NONE, MAP_ANONYMOUS|MAP_PRIVATE, -1, 0);
+	ret = pkey_mprotect(ptr, PAGE_SIZE, real_prot, pkey);
+	... application runs here
+
+Now, if the application needs to update the data at 'ptr', it can
+gain access, do the update, then remove its write access:
+
+	pkey_set(pkey, 0); // clear PKEY_DENY_WRITE
+	*ptr = foo; // assign something
+	pkey_set(pkey, PKEY_DENY_WRITE); // set PKEY_DENY_WRITE again
+
+Now when it frees the memory, it will also free the pkey since it
+is no longer in use:
+
+	munmap(ptr, PAGE_SIZE);
+	pkey_free(pkey);
+
+(Note: pkey_set() is a wrapper for the RDPKRU and WRPKRU instructions.
+ An example implementation can be found in
+ tools/testing/selftests/x86/protection_keys.c)
+
+=========================== Behavior ===========================
+
+The kernel attempts to make protection keys consistent with the
+behavior of a plain mprotect().  For instance if you do this:
+
+	mprotect(ptr, size, PROT_NONE);
+	something(ptr);
+
+you can expect the same effects with protection keys when doing this:
+
+	pkey = pkey_alloc(0, PKEY_DISABLE_WRITE | PKEY_DISABLE_READ);
+	pkey_mprotect(ptr, size, PROT_READ|PROT_WRITE, pkey);
+	something(ptr);
+
+That should be true whether something() is a direct access to 'ptr'
+like:
+
+	*ptr = foo;
+
+or when the kernel does the access on the application's behalf like
+with a read():
+
+	read(fd, ptr, 1);
+
+The kernel will send a SIGSEGV in both cases, but si_code will be set
+to SEGV_PKERR when violating protection keys versus SEGV_ACCERR when
+the plain mprotect() permissions are violated.

+/**
+ * DOC: overview
+ *
+ * The basic plane composition model supported by standard plane properties only
+ * has a source rectangle (in logical pixels within the &drm_framebuffer), with
+ * sub-pixel accuracy, which is scaled up to a pixel-aligned destination
+ * rectangle in the visible area of a &drm_crtc. The visible area of a CRTC is
+ * defined by the horizontal and vertical visible pixels (stored in @hdisplay
+ * and @vdisplay) of the requested mode (stored in @mode in the
+ * &drm_crtc_state). These two rectangles are both stored in the
+ * &drm_plane_state.
+ *
+ * For the atomic ioctl the following standard (atomic) properties on the plane object
+ * encode the basic plane composition model:
+ *
+ * SRC_X:
+ * 	X coordinate offset for the source rectangle within the
+ * 	&drm_framebuffer, in 16.16 fixed point. Must be positive.
+ * SRC_Y:
+ * 	Y coordinate offset for the source rectangle within the
+ * 	&drm_framebuffer, in 16.16 fixed point. Must be positive.
+ * SRC_W:
+ * 	Width for the source rectangle within the &drm_framebuffer, in 16.16
+ * 	fixed point. SRC_X plus SRC_W must be within the width of the source
+ * 	framebuffer. Must be positive.
+ * SRC_H:
+ * 	Height for the source rectangle within the &drm_framebuffer, in 16.16
+ * 	fixed point. SRC_Y plus SRC_H must be within the height of the source
+ * 	framebuffer. Must be positive.
+ * CRTC_X:
+ * 	X coordinate offset for the destination rectangle. Can be negative.
+ * CRTC_Y:
+ * 	Y coordinate offset for the destination rectangle. Can be negative.
+ * CRTC_W:
+ * 	Width for the destination rectangle. CRTC_X plus CRTC_W can extend past
+ * 	the currently visible horizontal area of the &drm_crtc.
+ * CRTC_H:
+ * 	Height for the destination rectangle. CRTC_Y plus CRTC_H can extend past
+ * 	the currently visible vertical area of the &drm_crtc.
+ * FB_ID:
+ * 	Mode object ID of the &drm_framebuffer this plane should scan out.
+ * CRTC_ID:
+ * 	Mode object ID of the &drm_crtc this plane should be connected to.
+ *
+ * Note that the source rectangle must fully lie within the bounds of the
+ * &drm_framebuffer. The destination rectangle can lie outside of the visible
+ * area of the current mode of the CRTC. It must be apprpriately clipped by the
+ * driver, which can be done by calling drm_plane_helper_check_update(). Drivers
+ * are also allowed to round the subpixel sampling positions appropriately, but
+ * only to the next full pixel. No pixel outside of the source rectangle may
+ * ever be sampled, which is important when applying more sophisticated
+ * filtering than just a bilinear one when scaling. The filtering mode when
+ * scaling is unspecified.
+ *
+ * On top of this basic transformation additional properties can be exposed by
+ * the driver:
+ *
+ * - Rotation is set up with drm_mode_create_rotation_property(). It adds a
+ *   rotation and reflection step between the source and destination rectangles.
+ *   Without this property the rectangle is only scaled, but not rotated or
+ *   reflected.
+ *
+ * - Z position is set up with drm_plane_create_zpos_immutable_property() and
+ *   drm_plane_create_zpos_property(). It controls the visibility of overlapping
+ *   planes. Without this property the primary plane is always below the cursor
+ *   plane, and ordering between all other planes is undefined.
+ *
+ * Note that all the property extensions described here apply either to the
+ * plane or the CRTC (e.g. for the background color, which currently is not
+ * exposed and assumed to be black).
+ */
+
+/**
+ * drm_mode_create_rotation_property - create a new rotation property
+ * @dev: DRM device
+ * @supported_rotations: bitmask of supported rotations and reflections
+ *
+ * This creates a new property with the selected support for transformations.
+ * The resulting property should be stored in @rotation_property in
+ * &drm_mode_config. It then must be attached to each plane which supports
+ * rotations using drm_object_attach_property().
+ *
+ * FIXME: Probably better if the rotation property is created on each plane,
+ * like the zpos property. Otherwise it's not possible to allow different
+ * rotation modes on different planes.
+ *
+ * Since a rotation by 180° degress is the same as reflecting both along the x
+ * and the y axis the rotation property is somewhat redundant. Drivers can use
+ * drm_rotation_simplify() to normalize values of this property.
+ *
+ * The property exposed to userspace is a bitmask property (see
+ * drm_property_create_bitmask()) called "rotation" and has the following
+ * bitmask enumaration values:
+ *
+ * DRM_ROTATE_0:
+ * 	"rotate-0"
+ * DRM_ROTATE_90:
+ * 	"rotate-90"
+ * DRM_ROTATE_180:
+ * 	"rotate-180"
+ * DRM_ROTATE_270:
+ * 	"rotate-270"
+ * DRM_REFLECT_X:
+ * 	"reflect-x"
+ * DRM_REFELCT_Y:
+ * 	"reflect-y"
+ *
+ * Rotation is the specified amount in degrees in counter clockwise direction,
+ * the X and Y axis are within the source rectangle, i.e.  the X/Y axis before
+ * rotation. After reflection, the rotation is applied to the image sampled from
+ * the source rectangle, before scaling it to fit the destination rectangle.

+ * There is also support for a legacy gamma table, which is set up by calling
+ * drm_mode_crtc_set_gamma_size(). Drivers which support both should use

+/**
+ * DOC: overview
+ *
+ * In DRM connectors are the general abstraction for display sinks, and include
+ * als fixed panels or anything else that can display pixels in some form. As
+ * opposed to all other KMS objects representing hardware (like CRTC, encoder or
+ * plane abstractions) connectors can be hotplugged and unplugged at runtime.
+ * Hence they are reference-counted using drm_connector_reference() and
+ * drm_connector_unreference().
+ *
+ * KMS driver must create, initialize, register and attach at a struct
+ * &drm_connector for each such sink. The instance is created as other KMS
+ * objects and initialized by setting the following fields.
+ *
+ * The connector is then registered with a call to drm_connector_init() with a
+ * pointer to the connector functions and a connector type, and exposed through
+ * sysfs with a call to drm_connector_register().
+ *
+ * Connectors must be attached to an encoder to be used. For devices that map
+ * connectors to encoders 1:1, the connector should be attached at
+ * initialization time with a call to drm_mode_connector_attach_encoder(). The
+ * driver must also set the struct &drm_connector encoder field to point to the
+ * attached encoder.
+ *
+ * For connectors which are not fixed (like built-in panels) the driver needs to
+ * support hotplug notifications. The simplest way to do that is by using the
+ * probe helpers, see drm_kms_helper_poll_init() for connectors which don't have
+ * hardware support for hotplug interrupts. Connectors with hardware hotplug
+ * support can instead use e.g. drm_helper_hpd_irq_event().

+/**
+ * DOC: overview
+ *
+ * Encoders represent the connecting element between the CRTC (as the overall
+ * pixel pipeline, represented by struct &drm_crtc) and the connectors (as the
+ * generic sink entity, represented by struct &drm_connector). An encoder takes
+ * pixel data from a CRTC and converts it to a format suitable for any attached
+ * connector. Encoders are objects exposed to userspace, originally to allow
+ * userspace to infer cloning and connector/CRTC restrictions. Unfortunately
+ * almost all drivers get this wrong, making the uabi pretty much useless. On
+ * top of that the exposed restrictions are too simple for today's hardware, and
+ * the recommended way to infer restrictions is by using the
+ * DRM_MODE_ATOMIC_TEST_ONLY flag for the atomic IOCTL.
+ *
+ * Otherwise encoders aren't used in the uapi at all (any modeset request from
+ * userspace directly connects a connector with a CRTC), drivers are therefore
+ * free to use them however they wish. Modeset helper libraries make strong use
+ * of encoders to facilitate code sharing. But for more complex settings it is
+ * usually better to move shared code into a separate &drm_bridge. Compared to
+ * encoders, bridges also have the benefit of being purely an internal
+ * abstraction since they are not exposed to userspace at all.
+ *
+ * Encoders are initialized with drm_encoder_init() and cleaned up using
+ * drm_encoder_cleanup().

+/**
+ * DOC: overview
+ *
+ * Frame buffers are abstract memory objects that provide a source of pixels to
+ * scanout to a CRTC. Applications explicitly request the creation of frame
+ * buffers through the DRM_IOCTL_MODE_ADDFB(2) ioctls and receive an opaque
+ * handle that can be passed to the KMS CRTC control, plane configuration and
+ * page flip functions.
+ *
+ * Frame buffers rely on the underlying memory manager for allocating backing
+ * storage. When creating a frame buffer applications pass a memory handle
+ * (or a list of memory handles for multi-planar formats) through the
+ * struct &drm_mode_fb_cmd2 argument. For drivers using GEM as their userspace
+ * buffer management interface this would be a GEM handle.  Drivers are however
+ * free to use their own backing storage object handles, e.g. vmwgfx directly
+ * exposes special TTM handles to userspace and so expects TTM handles in the
+ * create ioctl and not GEM handles.
+ *
+ * Framebuffers are tracked with struct &drm_framebuffer. They are published
+ * using drm_framebuffer_init() - after calling that function userspace can use
+ * and access the framebuffer object. The helper function
+ * drm_helper_mode_fill_fb_struct() can be used to pre-fill the required
+ * metadata fields.
+ *
+ * The lifetime of a drm framebuffer is controlled with a reference count,
+ * drivers can grab additional references with drm_framebuffer_reference() and
+ * drop them again with drm_framebuffer_unreference(). For driver-private
+ * framebuffers for which the last reference is never dropped (e.g. for the
+ * fbdev framebuffer when the struct struct &drm_framebuffer is embedded into
+ * the fbdev helper struct) drivers can manually clean up a framebuffer at
+ * module unload time with drm_framebuffer_unregister_private(). But doing this
+ * is not recommended, and it's better to have a normal free-standing struct
+ * &drm_framebuffer.

+ * rotation or Z-position. All these properties are stored in &drm_plane_state.

+ * To create a plane, a KMS drivers allocates and zeroes an instances of

+ * with a call to drm_universal_plane_init().
+ *
+ * Cursor and overlay planes are optional. All drivers should provide one
+ * primary plane per CRTC to avoid surprising userspace too much. See enum

+ * configuration from userspace to the kernel. Properties have a well-defined

+ * flags member of struct &drm_property for an overview of the different
+ * property types and ranges.
+ *
+ * Properties don't store the current value directly, but need to be
+ * instatiated by attaching them to a &drm_mode_object with
+ * drm_object_attach_property().
+ *
+ * Property values are only 64bit. To support bigger piles of data (like gamma
+ * tables, color correction matrizes or large structures) a property can instead
+ * point at a &drm_property_blob with that additional data
+ *
+ * Properties are defined by their symbolic name, userspace must keep a

+ * IOCTL and in the get/set property IOCTL.

+ *     object is too large for the available space (or simply too large
+ *     for the mappable aperture!), a view is created instead and faulted
+ *     into userspace. (This view is aligned and sized appropriately for
+ *     fenced access.)
+ *
+ * Restrictions:
+ *
+ *  * snoopable objects cannot be accessed via the GTT. It can cause machine
+ *    hangs on some architectures, corruption on others. An attempt to service
+ *    a GTT page fault from a snoopable object will generate a SIGBUS.
+ *
+ *  * the object must be able to fit into RAM (physical memory, though no
+ *    limited to the mappable aperture).
+ *
+ *
+ * Caveats:
+ *
+ *  * a new GTT page fault will synchronize rendering from the GPU and flush
+ *    all data to system memory. Subsequent access will not be synchronized.
+ *
+ *  * all mappings are revoked on runtime device suspend.
+ *
+ *  * there are only 8, 16 or 32 fence registers to share between all users
+ *    (older machines require fence register for display and blitter access
+ *    as well). Contention of the fence registers will cause the previous users

- * i915_gem_object_sync - sync an object to a ring.
- *
- * @obj: object which may be in use on another ring.
- * @to: ring we wish to use the object on. May be NULL.
- * @to_req: request we wish to use the object for. See below.
- *          This will be allocated and returned if a request is
- *          required but not passed in.
- *
- * This code is meant to abstract object synchronization with the GPU.
- * Calling with NULL implies synchronizing the object with the CPU
- * rather than a particular GPU ring. Conceptually we serialise writes
- * between engines inside the GPU. We only allow one engine to write
- * into a buffer at any time, but multiple readers. To ensure each has
- * a coherent view of memory, we must:
- *
- * - If there is an outstanding write request to the object, the new
- *   request must wait for it to complete (either CPU or in hw, requests
- *   on the same ring will be naturally ordered).
- *
- * - If we are a write request (pending_write_domain is set), the new
- *   request must wait for outstanding read requests to complete.
- *
- * For CPU synchronisation (NULL to) no request is required. For syncing with
- * rings to_req must be non-NULL. However, a request does not have to be
- * pre-allocated. If *to_req is NULL and sync commands will be emitted then a
- * request will be allocated automatically and returned through *to_req. Note
- * that it is not guaranteed that commands will be emitted (because the system
- * might already be idle). Hence there is no need to create a request that
- * might never have any work submitted. Note further that if a request is
- * returned in *to_req, it is the responsibility of the caller to submit
- * that request (after potentially adding more work to it).
- *
- * Returns 0 if successful, else propagates up the lower layer error.

+	 *
+	 * As we use SLAB_DESTROY_BY_RCU, the request may be reallocated

+	 * result is actually the wrong engine.
+	 *
+	 * So why don't we care?
+	 *
+	 * For starters, the busy ioctl is a heuristic that is by definition
+	 * racy. Even with perfect serialisation in the driver, the hardware
+	 * state is constantly advancing - the state we report to the user
+	 * is stale.
+	 *
+	 * The critical information for the busy-ioctl is whether the object
+	 * is idle as userspace relies on that to detect whether its next
+	 * access will stall, or if it has missed submitting commands to
+	 * the hardware allowing the GPU to stall. We never generate a
+	 * false-positive for idleness, thus busy-ioctl is reliable at the
+	 * most fundamental level, and we maintain the guarantee that a
+	 * busy object left to itself will eventually become idle (and stay
+	 * idle!).
+	 *
+	 * We allow ourselves the leeway of potentially misreporting the busy
+	 * state because that is an optimisation heuristic that is constantly
+	 * in flux. Being quickly able to detect the busy/idle state is much
+	 * more important than accurate logging of exactly which engines were
+	 * busy.

- * When setting up a new DDB allocation arrangement, we need to correctly
- * sequence the times at which the new allocations for the pipes are taken into
- * account or we'll have pipes fetching from space previously allocated to
- * another pipe.
- *
- * Roughly the sequence looks like:
- *  1. re-allocate the pipe(s) with the allocation being reduced and not
- *     overlapping with a previous light-up pipe (another way to put it is:
- *     pipes with their new allocation strickly included into their old ones).
- *  2. re-allocate the other pipes that get their allocation reduced
- *  3. allocate the pipes having their allocation increased
- *
- * Steps 1. and 2. are here to take care of the following case:
- * - Initially DDB looks like this:
- *     |   B    |   C    |
- * - enable pipe A.
- * - pipe B has a reduced DDB allocation that overlaps with the old pipe C
- *   allocation
- *     |  A  |  B  |  C  |
- *
- * We need to sequence the re-allocation: C, B, A (and not B, C, A).

+/*
+ * The IC Resizer has a restriction that the output frame from the
+ * resizer must be 1024 or less in both width (pixels) and height
+ * (lines).
+ *
+ * The image converter attempts to split up a conversion when
+ * the desired output (converted) frame resolution exceeds the
+ * IC resizer limit of 1024 in either dimension.
+ *
+ * If either dimension of the output frame exceeds the limit, the
+ * dimension is split into 1, 2, or 4 equal stripes, for a maximum
+ * of 4*4 or 16 tiles. A conversion is then carried out for each
+ * tile (but taking care to pass the full frame stride length to
+ * the DMA channel's parameter memory!). IDMA double-buffering is used
+ * to convert each tile back-to-back when possible (see note below
+ * when double_buffering boolean is set).
+ *
+ * Note that the input frame must be split up into the same number
+ * of tiles as the output frame.
+ *
+ * FIXME: at this point there is no attempt to deal with visible seams
+ * at the tile boundaries when upscaling. The seams are caused by a reset
+ * of the bilinear upscale interpolation when starting a new tile. The
+ * seams are barely visible for small upscale factors, but become
+ * increasingly visible as the upscale factor gets larger, since more
+ * interpolated pixels get thrown out at the tile boundaries. A possilble
+ * fix might be to overlap tiles of different sizes, but this must be done
+ * while also maintaining the IDMAC dma buffer address alignment and 8x8 IRT
+ * alignment restrictions of each tile.

- *     to lock read or write operations.
- *     Two or more readers must be locked against each other.
- *     Flushing the buffer counts as a read operation.

+/*
+ * BEWARE OF KNOWN ISSUES WITH VIDEO QUALITY
+ *
+ * This driver was developed by Bluecherry LLC by deducing behaviour of
+ * original manufacturer's driver, from both source code and execution traces.
+ * It is known that there are some artifacts on output video with this driver:
+ *  - on all known hardware samples: random pixels of wrong color (mostly
+ *    white, red or blue) appearing and disappearing on sequences of P-frames;
+ *  - on some hardware samples (known with H.264 core version e006:2800):
+ *    total madness on P-frames: blocks of wrong luminance; blocks of wrong
+ *    colors "creeping" across the picture.
+ * There is a workaround for both issues: avoid P-frames by setting GOP size
+ * to 1. To do that, run this command on device files created by this driver:
+ *
+ * v4l2-ctl --device /dev/videoX --set-ctrl=video_gop_size=1
+ *
+ * These issues are not decoding errors; all produced H.264 streams are decoded
+ * properly. Streams without P-frames don't have these artifacts so it's not
+ * analog-to-digital conversion issues nor internal memory errors; we conclude
+ * it's internal H.264 encoder issues.
+ * We cannot even check the original driver's behaviour because it has never
+ * worked properly at all in our development environment. So these issues may
+ * be actually related to firmware or hardware. However it may be that there's
+ * just some more register settings missing in the driver which would please
+ * the hardware.
+ * Manufacturer didn't help much on our inquiries, but feel free to disturb
+ * again the support of Intersil (owner of former Techwell).

+ * without holding any locks.
+ *
+ * It has 3 different events in total to allow a fine-grained synchronization
+ * between outstanding updates::
+ *
+ *	atomic commit thread			hardware

+ * 	write new state into hardware	---->	...
+ * 	signal hw_done
+ * 						switch to new state on next
+ * 	...					v/hblank
+ *
+ *	wait for buffers to show up		...
+ *
+ *	...					send completion irq
+ *						irq handler signals flip_done
+ *	cleanup old buffers
+ *
+ * 	signal cleanup_done
+ *
+ * 	wait for flip_done		<----
+ * 	clean up atomic state
+ *
+ * The important bit to know is that cleanup_done is the terminal event, but the
+ * ordering between flip_done and hw_done is entirely up to the specific driver
+ * and modeset state change.
+ *
+ * For an implementation of how to use this look at
+ * drm_atomic_helper_setup_commit() from the atomic helper library.

+ * of the property with the set of permissible values. This means that when a
+ * driver wants to use a property with the same name on different objects, but
+ * with different value ranges, then it must create property for each one. An
+ * example would be rotation of &drm_plane, when e.g. the primary plane cannot

+ * property structure can be instantiated multiple times for the same object.
+ * Userspace must be able to cope with this and cannot assume that the same
+ * symbolic property will have the same modeset object ID on all modeset
+ * objects.
+ *
+ * Properties are created by one of the special functions, as explained in
+ * detail in the @flags structure member.
+ *
+ * To actually expose a property it must be attached to each object using
+ * drm_object_attach_property(). Currently properties can only be attached to
+ * &drm_connector, &drm_crtc and &drm_plane.
+ *
+ * Properties are also used as the generic metadatatransport for the atomic
+ * IOCTL. Everything that was set directly in structures in the legacy modeset
+ * IOCTLs (like the plane source or destination windows, or e.g. the links to
+ * the CRTC) is exposed as a property with the DRM_MODE_PROP_ATOMIC flag set.

+	 *     The KMS core verifies that values set by application fit in that
+	 *     range. The range is unsigned. Range properties are created using
+	 *     drm_property_create_range().
+	 *
+	 * DRM_MODE_PROP_SIGNED_RANGE
+	 *     Range properties report their minimum and maximum admissible unsigned values.
+	 *     The KMS core verifies that values set by application fit in that
+	 *     range. The range is signed. Range properties are created using
+	 *     drm_property_create_signed_range().
+	 *
+	 * DRM_MODE_PROP_ENUM
+	 *     Enumerated properties take a numerical value that ranges from 0 to
+	 *     the number of enumerated values defined by the property minus one,
+	 *     and associate a free-formed string name to each value. Applications
+	 *     can retrieve the list of defined value-name pairs and use the
+	 *     numerical value to get and set property instance values. Enum
+	 *     properties are created using drm_property_create_enum().
+	 *
+	 * DRM_MODE_PROP_BITMASK
+	 *     Bitmask properties are enumeration properties that additionally
+	 *     restrict all enumerated values to the 0..63 range. Bitmask property
+	 *     instance values combine one or more of the enumerated bits defined
+	 *     by the property. Bitmask properties are created using
+	 *     drm_property_create_bitmask().
+	 *
+	 * DRM_MODE_PROB_OBJECT
+	 *     Object properties are used to link modeset objects. This is used
+	 *     extensively in the atomic support to create the display pipeline,
+	 *     by linking &drm_framebuffer to &drm_plane, &drm_plane to
+	 *     &drm_crtc and &drm_connector to &drm_crtc. An object property can
+	 *     only link to a specific type of &drm_mode_object, this limit is
+	 *     enforced by the core. Object properties are created using
+	 *     drm_property_create_object().
+	 *
+	 *     Object properties work like blob properties, but in a more
+	 *     general fashion. They are limited to atomic drivers and must have
+	 *     the DRM_MODE_PROP_ATOMIC flag set.
+	 *
+	 * DRM_MODE_PROP_BLOB
+	 *     Blob properties store a binary blob without any format restriction.
+	 *     The binary blobs are created as KMS standalone objects, and blob
+	 *     property instance values store the ID of their associated blob
+	 *     object. Blob properties are created by calling
+	 *     drm_property_create() with DRM_MODE_PROP_BLOB as the type.
+	 *
+	 *     Actual blob objects to contain blob data are created using
+	 *     drm_property_create_blob(), or through the corresponding IOCTL.
+	 *
+	 *     Besides the built-in limit to only accept blob objects blob
+	 *     properties work exactly like object properties. The only reasons
+	 *     blob properties exist is backwards compatibility with existing
+	 *     userspace.
+	 *
+	 * In addition a property can have any combination of the below flags:
+	 *
+	 * DRM_MODE_PROP_ATOMIC
+	 *     Set for properties which encode atomic modeset state. Such
+	 *     properties are not exposed to legacy userspace.
+	 *
+	 * DRM_MODE_PROP_IMMUTABLE
+	 *     Set for properties where userspace cannot be changed by
+	 *     userspace. The kernel is allowed to update the value of these
+	 *     properties. This is generally used to expose probe state to
+	 *     usersapce, e.g. the EDID, or the connector path property on DP

+ * The term "pair" is used here, even though TLC NANDs might group pages by 3

+ * the same cell. Pairs are then indexed in ascending order.
+ *
+ * @group is defining the position of a page in a given pair. It can also be
+ * seen as the bit position in the cell: page attached to bit 0 belongs to
+ * group 0, page attached to bit 1 belongs to group 1, etc.
+ *
+ * Example:
+ * The H27UCG8T2BTR-BC datasheet describes the following pairing scheme:
+ *
+ *		group-0		group-1
+ *
+ *  pair-0	page-0		page-4
+ *  pair-1	page-1		page-5
+ *  pair-2	page-2		page-8
+ *  ...
+ *  pair-127	page-251	page-255
+ *
+ *
+ * Note that the "group" and "pair" terms were extracted from Samsung and
+ * Hynix datasheets, and might be referenced under other names in other
+ * datasheets (Micron is describing this concept as "shared pages").

+
+The contents of this directory allow users to specify PMU events in their
+CPUs by their symbolic names rather than raw event codes (see example below).
+
+The main program in this directory, is the 'jevents', which is built and
+executed _BEFORE_ the perf binary itself is built.
+
+The 'jevents' program tries to locate and process JSON files in the directory
+tree tools/perf/pmu-events/arch/foo.
+
+	- Regular files with '.json' extension in the name are assumed to be
+	  JSON files, each of which describes a set of PMU events.
+
+	- Regular files with basename starting with 'mapfile.csv' are assumed
+	  to be a CSV file that maps a specific CPU to its set of PMU events.
+	  (see below for mapfile format)
+
+	- Directories are traversed, but all other files are ignored.
+
+The PMU events supported by a CPU model are expected to grouped into topics
+such as Pipelining, Cache, Memory, Floating-point etc. All events for a topic
+should be placed in a separate JSON file - where the file name identifies
+the topic. Eg: "Floating-point.json".
+
+All the topic JSON files for a CPU model/family should be in a separate
+sub directory. Thus for the Silvermont X86 CPU:
+
+	$ ls tools/perf/pmu-events/arch/x86/Silvermont_core
+	Cache.json 	Memory.json 	Virtual-Memory.json
+	Frontend.json 	Pipeline.json
+
+Using the JSON files and the mapfile, 'jevents' generates the C source file,
+'pmu-events.c', which encodes the two sets of tables:
+
+	- Set of 'PMU events tables' for all known CPUs in the architecture,
+	  (one table like the following, per JSON file; table name 'pme_power8'
+	  is derived from JSON file name, 'power8.json').
+
+		struct pmu_event pme_power8[] = {
+
+			...
+
+			{
+				.name = "pm_1plus_ppc_cmpl",
+				.event = "event=0x100f2",
+				.desc = "1 or more ppc insts finished,",
+			},
+
+			...
+		}
+
+	- A 'mapping table' that maps each CPU of the architecture, to its
+	  'PMU events table'
+
+		struct pmu_events_map pmu_events_map[] = {
+		{
+			.cpuid = "004b0000",
+			.version = "1",
+			.type = "core",
+			.table = pme_power8
+		},
+			...
+
+		};
+
+After the 'pmu-events.c' is generated, it is compiled and the resulting
+'pmu-events.o' is added to 'libperf.a' which is then used to build perf.
+
+NOTES:
+	1. Several CPUs can support same set of events and hence use a common
+	   JSON file. Hence several entries in the pmu_events_map[] could map
+	   to a single 'PMU events table'.
+
+	2. The 'pmu-events.h' has an extern declaration for the mapping table
+	   and the generated 'pmu-events.c' defines this table.
+
+	3. _All_ known CPU tables for architecture are included in the perf
+	   binary.
+
+At run time, perf determines the actual CPU it is running on, finds the
+matching events table and builds aliases for those events. This allows
+users to specify events by their name:
+
+	$ perf stat -e pm_1plus_ppc_cmpl sleep 1
+
+where 'pm_1plus_ppc_cmpl' is a Power8 PMU event.
+
+In case of errors when processing files in the tools/perf/pmu-events/arch
+directory, 'jevents' tries to create an empty mapping file to allow the perf
+build to succeed even if the PMU event aliases cannot be used.
+
+However some errors in processing may cause the perf build to fail.
+
+Mapfile format
+===============
+
+The mapfile enables multiple CPU models to share a single set of PMU events.
+It is required even if such mapping is 1:1.
+
+The mapfile.csv format is expected to be:
+
+	Header line
+	CPUID,Version,Dir/path/name,Type
+
+where:
+
+	Comma:
+		is the required field delimiter (i.e other fields cannot
+		have commas within them).
+
+	Comments:
+		Lines in which the first character is either '\n' or '#'
+		are ignored.
+
+	Header line
+		The header line is the first line in the file, which is
+		always _IGNORED_. It can empty.
+
+	CPUID:
+		CPUID is an arch-specific char string, that can be used
+		to identify CPU (and associate it with a set of PMU events
+		it supports). Multiple CPUIDS can point to the same
+		File/path/name.json.
+
+		Example:
+			CPUID == 'GenuineIntel-6-2E' (on x86).
+			CPUID == '004b0100' (PVR value in Powerpc)
+	Version:
+		is the Version of the mapfile.
+
+	Dir/path/name:
+		is the pathname to the directory containing the CPU's JSON
+		files, relative to the directory containing the mapfile.csv
+
+	Type:
+		indicates whether the events or "core" or "uncore" events.
+
+
+	Eg:
+
+	$ grep Silvermont tools/perf/pmu-events/arch/x86/mapfile.csv
+	GenuineIntel-6-37,V13,Silvermont_core,core
+	GenuineIntel-6-4D,V13,Silvermont_core,core
+	GenuineIntel-6-4C,V13,Silvermont_core,core
+
+	i.e the three CPU models use the JSON files (i.e PMU events) listed
+	in the directory 'tools/perf/pmu-events/arch/x86/Silvermont_core'.

+/*
+ * Tests x86 Memory Protection Keys (see Documentation/x86/protection-keys.txt)
+ *
+ * There are examples in here of:
+ *  * how to set protection keys on memory
+ *  * how to set/clear bits in PKRU (the rights register)
+ *  * how to handle SEGV_PKRU signals and extract pkey-relevant
+ *    information from the siginfo
+ *
+ * Things to add:
+ *	make sure KSM and KSM COW breaking works
+ *	prefault pages in at malloc, or not
+ *	protect MPX bounds tables with protection keys?
+ *	make sure VMA splitting/merging is working correctly
+ *	OOMs can destroy mm->mmap (see exit_mmap()), so make sure it is immune to pkeys
+ *	look for pkey "leaks" where it is still set on a VMA but "freed" back to the kernel
+ *	do a plain mprotect() to a mprotect_pkey() area and make sure the pkey sticks
+ *
+ * Compile like this:
+ *	gcc      -o protection_keys    -O2 -g -std=gnu99 -pthread -Wall protection_keys.c -lrt -ldl -lm
+ *	gcc -m32 -o protection_keys_32 -O2 -g -std=gnu99 -pthread -Wall protection_keys.c -lrt -ldl -lm
