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 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.
-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.
+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.
-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.
+There are a few areas these helpers can grouped into:
-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.
+* 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.
+.. kernel-doc:: drivers/gpu/drm/drm_framebuffer.c
+ :doc: overview
-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.
+Frame Buffer Functions Reference
+--------------------------------
-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

-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
-
-- DRM_MODE_CONNECTOR_VGA
-- DRM_MODE_CONNECTOR_DVII
-- DRM_MODE_CONNECTOR_DVID
-- DRM_MODE_CONNECTOR_DVIA
-- DRM_MODE_CONNECTOR_Composite
-- DRM_MODE_CONNECTOR_SVIDEO
-- DRM_MODE_CONNECTOR_LVDS
-- DRM_MODE_CONNECTOR_Component
-- DRM_MODE_CONNECTOR_9PinDIN
-- DRM_MODE_CONNECTOR_DisplayPort
-- DRM_MODE_CONNECTOR_HDMIA
-- DRM_MODE_CONNECTOR_HDMIB
-- DRM_MODE_CONNECTOR_TV
-- DRM_MODE_CONNECTOR_eDP
-- DRM_MODE_CONNECTOR_VIRTUAL
-
-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
-:c:func:`drm_mode_connector_attach_encoder()`. The driver must
-also set the :c:type:`struct drm_connector <drm_connector>`
-encoder field to point to the attached encoder.
-
-Finally, drivers must initialize the connectors state change detection
-with a call to :c:func:`drm_kms_helper_poll_init()`. If at least
-one connector is pollable but can't generate hotplug interrupts
-(indicated by the DRM_CONNECTOR_POLL_CONNECT and
-DRM_CONNECTOR_POLL_DISCONNECT connector flags), a delayed work will
-automatically be queued to periodically poll for changes. Connectors
-that can generate hotplug interrupts must be marked with the
-DRM_CONNECTOR_POLL_HPD flag instead, and their interrupt handler must
-call :c:func:`drm_helper_hpd_irq_event()`. The function will
-queue a delayed work to check the state of all connectors, but no
-periodic polling will be done.
-
-Connector Operations
-~~~~~~~~~~~~~~~~~~~~
-
- **Note**
-
- Unless otherwise state, all operations are mandatory.
-
-DPMS
-''''
-
-void (\*dpms)(struct drm_connector \*connector, int mode);
-The DPMS operation sets the power state of a connector. The mode
-argument is one of
-
-- DRM_MODE_DPMS_ON
-
-- DRM_MODE_DPMS_STANDBY
-
-- DRM_MODE_DPMS_SUSPEND
-
-- DRM_MODE_DPMS_OFF
-
-In all but DPMS_ON mode the encoder to which the connector is attached
-should put the display in low-power mode by driving its signals
-appropriately. If more than one connector is attached to the encoder
-care should be taken not to change the power state of other displays as
-a side effect. Low-power mode should be propagated to the encoders and
-CRTCs when all related connectors are put in low-power mode.
-
-Modes
-'''''
-
-int (\*fill_modes)(struct drm_connector \*connector, uint32_t
-max_width, uint32_t max_height);
-Fill the mode list with all supported modes for the connector. If the
-``max_width`` and ``max_height`` arguments are non-zero, the
-implementation must ignore all modes wider than ``max_width`` or higher
-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
-supported (see ?). The status value is reported to userspace through
-ioctls and must not be used inside the driver, as it only gets
-initialized by a call to :c:func:`drm_mode_getconnector()` from
-userspace.
-
-enum drm_connector_status (\*detect)(struct drm_connector
-\*connector, bool force);
-Check to see if anything is attached to the connector. The ``force``
-parameter is set to false whilst polling or to true when checking the
-connector due to user request. ``force`` can be used by the driver to
-avoid expensive, destructive operations during automated probing.
-
-Return connector_status_connected if something is connected to the
-connector, connector_status_disconnected if nothing is connected and
-connector_status_unknown if the connection state isn't known.
-
-Drivers should only return connector_status_connected if the
-connection status has really been probed as connected. Connectors that
-can't detect the connection status, or failed connection status probes,
-should return connector_status_unknown.

-
-Properties can additionally be created as immutable, in which case they

+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.

+Validating changes with IGT
+===========================
+
+There's a collection of tests that aims to cover the whole functionality of
+DRM drivers and that can be used to check that changes to DRM drivers or the
+core don't regress existing functionality. This test suite is called IGT and
+its code can be found in https://cgit.freedesktop.org/drm/igt-gpu-tools/.
+
+To build IGT, start by installing its build dependencies. In Debian-based
+systems::
+
+ # apt-get build-dep intel-gpu-tools
+
+And in Fedora-based systems::
+
+ # dnf builddep intel-gpu-tools
+
+Then clone the repository::
+
+ $ git clone git://anongit.freedesktop.org/drm/igt-gpu-tools
+
+Configure the build system and start the build::
+
+ $ cd igt-gpu-tools && ./autogen.sh && make -j6
+
+Download the piglit dependency::
+
+ $ ./scripts/run-tests.sh -d
+
+And run the tests::
+
+ $ ./scripts/run-tests.sh -t kms -t core -s
+
+run-tests.sh is a wrapper around piglit that will execute the tests matching
+the -t options. A report in HTML format will be available in
+./results/html/index.html. Results can be compared with piglit.

+/**
+ * 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:

+ * "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.

+ * Color management or color space adjustments is supported through a set of 5
+ * properties on the &drm_crtc object. They are set up by calling
+ * drm_crtc_enable_color_mgmt().
+ *
+ * "DEGAMMA_LUT”:
+ * Blob property to set the degamma lookup table (LUT) mapping pixel data
+ * from the framebuffer before it is given to the transformation matrix.
+ * The data is interpreted as an array of struct &drm_color_lut elements.
+ * Hardware might choose not to use the full precision of the LUT elements
+ * nor use all the elements of the LUT (for example the hardware might
+ * choose to interpolate between LUT[0] and LUT[4]).
+ *
+ * “DEGAMMA_LUT_SIZE”:
+ * Unsinged range property to give the size of the lookup table to be set
+ * on the DEGAMMA_LUT property (the size depends on the underlying
+ * hardware). If drivers support multiple LUT sizes then they should
+ * publish the largest size, and sub-sample smaller sized LUTs (e.g. for
+ * split-gamma modes) appropriately.
+ *
+ * “CTM”:
+ * Blob property to set the current transformation matrix (CTM) apply to
+ * pixel data after the lookup through the degamma LUT and before the
+ * lookup through the gamma LUT. The data is interpreted as a struct
+ * &drm_color_ctm.
+ *
+ * “GAMMA_LUT”:
+ * Blob property to set the gamma lookup table (LUT) mapping pixel data
+ * after the transformation matrix to data sent to the connector. The
+ * data is interpreted as an array of struct &drm_color_lut elements.
+ * Hardware might choose not to use the full precision of the LUT elements
+ * nor use all the elements of the LUT (for example the hardware might
+ * choose to interpolate between LUT[0] and LUT[4]).
+ *
+ * “GAMMA_LUT_SIZE”:
+ * Unsigned range property to give the size of the lookup table to be set
+ * on the GAMMA_LUT property (the size depends on the underlying hardware).
+ * If drivers support multiple LUT sizes then they should publish the
+ * largest size, and sub-sample smaller sized LUTs (e.g. for split-gamma
+ * modes) appropriately.
+ *
+ * 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
+ * drm_atomic_helper_legacy_gamma_set() to alias the legacy gamma ramp with the
+ * "GAMMA_LUT" property above.

+ * 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.

+ * 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.

+ * 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

- * @to_req: request we wish to use the object for. See below.
- * This will be allocated and returned if a request is

- *
- * 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.

+ * wrong engine as being busy (but we guarantee that the result
+ * is at least self-consistent).
+ *
+ * As we use SLAB_DESTROY_BY_RCU, the request may be reallocated
+ * whilst we are inspecting it, even under the RCU read lock as we are.
+ * This means that there is a small window for the engine and/or the
+ * seqno to have been overwritten. The seqno will always be in the
+ * future compared to the intended, and so we know that if that
+ * seqno is idle (on whatever engine) our request is idle and the
+ * return 0 above is correct.
+ *
+ * The issue is that if the engine is switched, it is just as likely
+ * to report that it is busy (but since the switch happened, we know
+ * the request should be idle). So there is a small chance that a busy
+ * 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

- * Roughly the sequence looks like:

- * 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.

+ * The arbiter will first look for all VGA cards that might conflict and disable

+ * necessary, so that the requested resources can be used. Then, the card is
+ * marked as locking these resources and the IO and/or Memory accesses are

+ *
+ * This function will block if some conflicting card is already locking one of
+ * the required resources (or any resource on a different bus segment, since P2P
+ * bridges don't differentiate VGA memory and IO afaik). You can indicate
+ * whether this blocking should be interruptible by a signal (for userland
+ * interface) or not.
+ *
+ * Must not be called at interrupt time or in atomic context. If the card

+ * 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
