+/**
+ * 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).
+ */

+/**

+ * @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

+ * rotations using drm_object_attach_property().

+ *
+ * “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

+/**
+ * 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.

+/**
+ * DOC: overview
+ *
+ * A plane represents an image source that can be blended with or overlayed on
+ * top of a CRTC during the scanout process. Planes take their input data from a
+ * &drm_framebuffer object. The plane itself specifies the cropping and scaling
+ * of that image, and where it is placed on the visible are of a display
+ * pipeline, represented by &drm_crtc. A plane can also have additional
+ * properties that specify how the pixels are positioned and blended, like
+ * 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
+ * struct &drm_plane (possibly as part of a larger structure) and registers it
+ * 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
+ * &drm_plane_type for a more in-depth discussion of these special uapi-relevant
+ * plane types. Special planes are associated with their CRTC by calling
+ * drm_crtc_init_with_planes().
+ *
+ * The type of a plane is exposed in the immutable "type" enumeration property,
+ * which has one of the following values: "Overlay", "Primary", "Cursor".

+ * DOC: overview
+ *
+ * Properties as represented by &drm_property are used to extend the modeset
+ * interface exposed to userspace. For the atomic modeset IOCTL properties are
+ * even the only way to transport metadata about the desired new modeset
+ * configuration from userspace to the kernel. Properties have a well-defined
+ * value range, which is enforced by the drm core. See the documentation of the
+ * 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
+ * per-object mapping from those names to the property ID used in the atomic
+ * IOCTL and in the get/set property IOCTL.

+ *
+ * 0 - Everything had to fit into the GTT. Both parties of a memcpy had to
+ *     aligned and suitable for fencing, and still fit into the available
+ *     mappable space left by the pinned display objects. A classic problem
+ *     we called the page-fault-of-doom where we would ping-pong between
+ *     two objects that could not fit inside the GTT and so the memcpy
+ *     would page one object in at the expense of the other between every
+ *     single byte.
+ *
+ * 1 - Objects can be any size, and have any compatible fencing (X Y, or none
+ *     as set via i915_gem_set_tiling() [DRM_I915_GEM_SET_TILING]). If the
+ *     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
+ *    to be unmapped and any new access will generate new page faults.
+ *
+ *  * running out of memory while servicing a fault may generate a SIGBUS,
+ *    rather than the expected SIGSEGV.

-/**
- * 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

+	 * 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.

+ *
+ * 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

+ * interface) or not.
+ *
+ * Must not be called at interrupt time or in atomic context.  If the card

+ * @set_vga_decode: vga decode change callback
+ *
+ * Clients have two callback mechanisms they can use.
+ *
+ * @irq_set_state callback: If a client can't disable its GPUs VGA
+ * resources, then we need to be able to ask it to turn off its irqs when we
+ * turn off its mem and io decoding.
+ *
+ * @set_vga_decode callback: If a client can disable its GPU VGA resource, it
+ * will get a callback from this to set the encode/decode state.
+ *
+ * Rationale: we cannot disable VGA decode resources unconditionally some single
+ * GPU laptops seem to require ACPI or BIOS access to the VGA registers to
+ * control things like backlights etc.  Hopefully newer multi-GPU laptops do
+ * something saner, and desktops won't have any special ACPI for this. The
+ * driver will get a callback when VGA arbitration is first used by userspace
+ * since some older X servers have issues.
+ *
+ * This function does not check whether a client for @pdev has been registered
+ * already.
+ *
+ * To unregister just call this function with @irq_set_state and @set_vga_decode
+ * both set to NULL for the same @pdev as originally used to register them.
+ *
+ * Returns: 0 on success, -1 on failure
