+/**
+ * DOC: overview
+ *
+ * In the DRM subsystem, framebuffer pixel formats are described using the
+ * fourcc codes defined in `include/uapi/drm/drm_fourcc.h`. In addition to the
+ * fourcc code, a Format Modifier may optionally be provided, in order to
+ * further describe the buffer's format - for example tiling or compression.
+ *
+ * Format Modifiers
+ * ----------------
+ *
+ * Format modifiers are used in conjunction with a fourcc code, forming a
+ * unique fourcc:modifier pair. This format:modifier pair must fully define the
+ * format and data layout of the buffer, and should be the only way to describe
+ * that particular buffer.
+ *
+ * Having multiple fourcc:modifier pairs which describe the same layout should
+ * be avoided, as such aliases run the risk of different drivers exposing
+ * different names for the same data format, forcing userspace to understand
+ * that they are aliases.
+ *
+ * Format modifiers may change any property of the buffer, including the number
+ * of planes and/or the required allocation size. Format modifiers are
+ * vendor-namespaced, and as such the relationship between a fourcc code and a
+ * modifier is specific to the modifer being used. For example, some modifiers
+ * may preserve meaning - such as number of planes - from the fourcc code,
+ * whereas others may not.
+ *
+ * Modifiers must uniquely encode buffer layout. In other words, a buffer must
+ * match only a single modifier. A modifier must not be a subset of layouts of
+ * another modifier. For instance, it's incorrect to encode pitch alignment in
+ * a modifier: a buffer may match a 64-pixel aligned modifier and a 32-pixel
+ * aligned modifier. That said, modifiers can have implicit minimal
+ * requirements.
+ *
+ * For modifiers where the combination of fourcc code and modifier can alias,
+ * a canonical pair needs to be defined and used by all drivers. Preferred
+ * combinations are also encouraged where all combinations might lead to
+ * confusion and unnecessarily reduced interoperability. An example for the
+ * latter is AFBC, where the ABGR layouts are preferred over ARGB layouts.
+ *
+ * There are two kinds of modifier users:
+ *
+ * - Kernel and user-space drivers: for drivers it's important that modifiers
+ * don't alias, otherwise two drivers might support the same format but use
+ * different aliases, preventing them from sharing buffers in an efficient
+ * format.
+ * - Higher-level programs interfacing with KMS/GBM/EGL/Vulkan/etc: these users
+ * see modifiers as opaque tokens they can check for equality and intersect.
+ * These users musn't need to know to reason about the modifier value
+ * (i.e. they are not expected to extract information out of the modifier).
+ *
+ * Vendors should document their modifier usage in as much detail as
+ * possible, to ensure maximum compatibility across devices, drivers and
+ * applications.
+ *
+ * The authoritative list of format modifier codes is found in
+ * `include/uapi/drm/drm_fourcc.h`
+ *
+ * Open Source User Waiver
+ * -----------------------
+ *
+ * Because this is the authoritative source for pixel formats and modifiers
+ * referenced by GL, Vulkan extensions and other standards and hence used both
+ * by open source and closed source driver stacks, the usual requirement for an
+ * upstream in-kernel or open source userspace user does not apply.
+ *
+ * To ensure, as much as feasible, compatibility across stacks and avoid
+ * confusion with incompatible enumerations stakeholders for all relevant driver
+ * stacks should approve additions.

+ * Within each plane, the pixel/luma/chroma values are grouped into
+ * "coding unit" blocks which are individually compressed to a

+ * ioctl to register a new frame-buffer. The new frame-buffer object ID will
+ * be set by the kernel in @fb_id.
+ * - User-space can set @fb_id and perform a &DRM_IOCTL_MODE_GETFB2 ioctl to
+ * fetch metadata about an existing frame-buffer.
+ *
+ * In case of planar formats, this struct allows up to 4 buffer objects with
+ * offsets and pitches per plane. The pitch and offset order are dictated by
+ * the format FourCC as defined by ``drm_fourcc.h``, e.g. NV12 is described as:
+ *
+ * YUV 4:2:0 image with a plane of 8-bit Y samples followed by an
+ * interleaved U/V plane containing 8-bit 2x2 subsampled colour difference
+ * samples.
+ *
+ * So it would consist of a Y plane at ``offsets[0]`` and a UV plane at
+ * ``offsets[1]``.
+ *
+ * To accommodate tiled, compressed, etc formats, a modifier can be specified.
+ * For more information see the "Format Modifiers" section. Note that even
+ * though it looks like we have a modifier per-plane, we in fact do not. The
+ * modifier for each plane must be identical. Thus all combinations of
+ * different data layouts for multi-plane formats must be enumerated as
+ * separate modifiers.
+ *
+ * All of the entries in @handles, @pitches, @offsets and @modifier must be
+ * zero when unused. Warning, for @offsets and @modifier zero can't be used to
+ * figure out whether the entry is used or not since it's a valid value (a zero

+ * non-internal JOBS have been completed. Note that if the CS has internal JOBS
+ * which can execute AFTER the external JOBS have finished, the driver might
+ * report that the CS has finished executing BEFORE the internal JOBS have
+ * actually finished executing.
+ *
+ * Even though the sequence number increments per CS, the user can NOT
+ * automatically assume that if CS with sequence number N finished, then CS
+ * with sequence number N-1 also finished. The user can make this assumption if
+ * and only if CS N and CS N-1 are exactly the same (same CBs for the same

+/**
+ * struct i915_user_extension - Base class for defining a chain of extensions
+ *
+ * Many interfaces need to grow over time. In most cases we can simply
+ * extend the struct and have userspace pass in more data. Another option,
+ * as demonstrated by Vulkan's approach to providing extensions for forward
+ * and backward compatibility, is to use a list of optional structs to
+ * provide those extra details.
+ *
+ * The key advantage to using an extension chain is that it allows us to
+ * redefine the interface more easily than an ever growing struct of
+ * increasing complexity, and for large parts of that interface to be
+ * entirely optional. The downside is more pointer chasing; chasing across
+ * the __user boundary with pointers encapsulated inside u64.
+ *
+ * Example chaining:
+ *
+ * .. code-block:: C
+ *
+ * struct i915_user_extension ext3 {
+ * .next_extension = 0, // end
+ * .name = ...,
+ * };
+ * struct i915_user_extension ext2 {
+ * .next_extension = (uintptr_t)&ext3,
+ * .name = ...,
+ * };
+ * struct i915_user_extension ext1 {
+ * .next_extension = (uintptr_t)&ext2,
+ * .name = ...,
+ * };
+ *
+ * Typically the struct i915_user_extension would be embedded in some uAPI
+ * struct, and in this case we would feed it the head of the chain(i.e ext1),
+ * which would then apply all of the above extensions.

+ * A return of 0 implies that the object is idle (after
+ * having flushed any pending activity), and a non-zero return that
+ * the object is still in-flight on the GPU. (The GPU has not yet
+ * signaled completion for all pending requests that reference the
+ * object.) An object is guaranteed to become idle eventually (so
+ * long as no new GPU commands are executed upon it). Due to the
+ * asynchronous nature of the hardware, an object reported
+ * as busy may become idle before the ioctl is completed.
+ *
+ * Furthermore, if the object is busy, which engine is busy is only
+ * provided as a guide and only indirectly by reporting its class
+ * (there may be more than one engine in each class). There are race
+ * conditions which prevent the report of which engines are busy from
+ * being always accurate. However, the converse is not true. If the
+ * object is idle, the result of the ioctl, that all engines are idle,
+ * is accurate.
+ *
+ * The returned dword is split into two fields to indicate both
+ * the engine classess on which the object is being read, and the
+ * engine class on which it is currently being written (if any).
+ *
+ * The low word (bits 0:15) indicate if the object is being written
+ * to by any engine (there can only be one, as the GEM implicit
+ * synchronisation rules force writes to be serialised). Only the
+ * engine class (offset by 1, I915_ENGINE_CLASS_RENDER is reported as
+ * 1 not 0 etc) for the last write is reported.
+ *
+ * The high word (bits 16:31) are a bitmask of which engines classes
+ * are currently reading from the object. Multiple engines may be
+ * reading from the object simultaneously.
+ *
+ * The value of each engine class is the same as specified in the
+ * I915_CONTEXT_PARAM_ENGINES context parameter and via perf, i.e.
+ * I915_ENGINE_CLASS_RENDER, I915_ENGINE_CLASS_COPY, etc.
+ * Some hardware may have parallel execution engines, e.g. multiple
+ * media engines, which are mapped to the same class identifier and so
+ * are not separately reported for busyness.
+ *
+ * Caveat emptor:
+ * Only the boolean result of this query is reliable; that is whether
+ * the object is idle or busy. The report of which engines are busy
+ * should be only used as a heuristic.

+ * ppGTT support, or if the object is used for scanout). Note that this might
+ * require unbinding the object from the GTT first, if its current caching value
+ * doesn't match.
+ *
+ * Note that this all changes on discrete platforms, starting from DG1, the
+ * set/get caching is no longer supported, and is now rejected. Instead the CPU
+ * caching attributes(WB vs WC) will become an immutable creation time property
+ * for the object, along with the GTT caching level. For now we don't expose any
+ * new uAPI for this, instead on DG1 this is all implicit, although this largely
+ * shouldn't matter since DG1 is coherent by default(without any way of
+ * controlling it).
+ *
+ * Implicit caching rules, starting from DG1:
+ *
+ * - If any of the object placements (see &drm_i915_gem_create_ext_memory_regions)

+ * mapped as write-combined only.
+ *
+ * - Everything else is always allocated and mapped as write-back, with the
+ * guarantee that everything is also coherent with the GPU.
+ *
+ * Note that this is likely to change in the future again, where we might need
+ * more flexibility on future devices, so making this all explicit as part of a
+ * new &drm_i915_gem_create_ext extension is probable.
+ *
+ * Side note: Part of the reason for this is that changing the at-allocation-time CPU
+ * caching attributes for the pages might be required(and is expensive) if we
+ * need to then CPU map the pages later with different caching attributes. This
+ * inconsistent caching behaviour, while supported on x86, is not universally
+ * supported on other architectures. So for simplicity we opt for setting

+ * struct i915_context_engines_parallel_submit - Configure engine for
+ * parallel submission.
+ *
+ * Setup a slot in the context engine map to allow multiple BBs to be submitted
+ * in a single execbuf IOCTL. Those BBs will then be scheduled to run on the GPU
+ * in parallel. Multiple hardware contexts are created internally in the i915 to
+ * run these BBs. Once a slot is configured for N BBs only N BBs can be
+ * submitted in each execbuf IOCTL and this is implicit behavior e.g. The user
+ * doesn't tell the execbuf IOCTL there are N BBs, the execbuf IOCTL knows how
+ * many BBs there are based on the slot's configuration. The N BBs are the last
+ * N buffer objects or first N if I915_EXEC_BATCH_FIRST is set.
+ *
+ * The default placement behavior is to create implicit bonds between each
+ * context if each context maps to more than 1 physical engine (e.g. context is
+ * a virtual engine). Also we only allow contexts of same engine class and these
+ * contexts must be in logically contiguous order. Examples of the placement
+ * behavior are described below. Lastly, the default is to not allow BBs to be
+ * preempted mid-batch. Rather insert coordinated preemption points on all
+ * hardware contexts between each set of BBs. Flags could be added in the future
+ * to change both of these default behaviors.
+ *
+ * Returns -EINVAL if hardware context placement configuration is invalid or if
+ * the placement configuration isn't supported on the platform / submission
+ * interface.
+ * Returns -ENODEV if extension isn't supported on the platform / submission
+ * interface.

+ * set_engines(INVALID)
+ * set_parallel(engine_index=0, width=2, num_siblings=1,

+ *
+ * Results in the following valid placements:
+ * CS[0], CS[1]
+ * CS[2], CS[3]
+ *
+ * This can be thought of as two virtual engines, each containing two

+ * DOC: Context Engine Map uAPI
+ *
+ * Context engine map is a new way of addressing engines when submitting batch-

+ *
+ * To use it created GEM contexts need to be configured with a list of engines

+ * As an example, on discrete devices, if we wish to set the placement as

+ *
+ * .. code-block:: C
+ *
+ * struct drm_i915_gem_memory_class_instance region_lmem = {
+ * .memory_class = I915_MEMORY_CLASS_DEVICE,

+ *
+ * int err = ioctl(fd, DRM_IOCTL_I915_GEM_CREATE_EXT, &create_ext);
+ * if (err) ...
+ *
+ * At which point we get the object handle in &drm_i915_gem_create_ext.handle,
+ * along with the final object size in &drm_i915_gem_create_ext.size, which
+ * should account for any rounding up, if required.
+ *
+ * Note that userspace has no means of knowing the current backing region
+ * for objects where @num_regions is larger than one. The kernel will only
+ * ensure that the priority order of the @regions array is honoured, either
+ * when initially placing the object, or when moving memory around due to
+ * memory pressure
+ *
+ * On Flat-CCS capable HW, compression is supported for the objects residing
+ * in I915_MEMORY_CLASS_DEVICE. When such objects (compressed) have other
+ * memory class in @regions and migrated (by i915, due to memory
+ * constraints) to the non I915_MEMORY_CLASS_DEVICE region, then i915 needs to
+ * decompress the content. But i915 doesn't have the required information to
+ * decompress the userspace compressed objects.
+ *
+ * So i915 supports Flat-CCS, on the objects which can reside only on
+ * I915_MEMORY_CLASS_DEVICE regions.
