* There can be more then one JOB per queue.
*
* The CS IOCTL will receive two sets of JOBS. One set is for "restore" phase
* and a second set is for "execution" phase.
* The JOBS on the "restore" phase are enqueued only after context-switch
* (or if its the first CS for this context). The user can also order the
* driver to run the "restore" phase explicitly
*
* Goya/Gaudi:
* There are two types of queues - external and internal. External queues
* are DMA queues which transfer data from/to the Host. All other queues are
* internal. The driver will get completion notifications from the device only
* on JOBS which are enqueued in the external queues.
*
* Greco onwards:
* There is a single type of queue for all types of engines, either DMA engines
* for transfers from/to the host or inside the device, or compute engines.
* The driver will get completion notifications from the device for all queues.
*
* For jobs on external queues, the user needs to create command buffers
* through the CB ioctl and give the CB's handle to the CS ioctl. For jobs on
* internal queues, the user needs to prepare a "command buffer" with packets
* on either the device SRAM/DRAM or the host, and give the device address of
* that buffer to the CS ioctl.
* For jobs on H/W queues both options of command buffers are valid.
*
* This IOCTL is asynchronous in regard to the actual execution of the CS. This
* means it returns immediately after ALL the JOBS were enqueued on their
* relevant queues. Therefore, the user mustn't assume the CS has been completed
* or has even started to execute.
*
* Upon successful enqueue, the IOCTL returns a sequence number which the user
* can use with the "Wait for CS" IOCTL to check whether the handle's CS
* 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

/**
* 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

*
* 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.

* To calculate the padding, it is assumed that each hardware block
* and the software driving it knows the platform's SDRAM page size,
* number of banks, and XOR address, and that it's identical between
* all blocks using the format. This tiling modifier will use XOR as
* necessary to reduce the padding. If a hardware block can't do XOR,

* Arm Fixed-Rate Compression (AFRC) modifiers
*
* AFRC is a proprietary fixed rate image compression protocol and format,

*
* AFRC buffers consist of one or more planes, with the same components
* and meaning as an uncompressed buffer using the same pixel format.
*
* Within each plane, the pixel/luma/chroma values are grouped into
* "coding unit" blocks which are individually compressed to a
* fixed size (in bytes). All coding units within a given plane of a buffer
* store the same number of values, and have the same compressed size.
*
* The coding unit size is configurable, allowing different rates of compression.
*
* The start of each AFRC buffer plane must be aligned to an alignment granule which
* depends on the coding unit size.
*
* Coding Unit Size Plane Alignment
* ---------------- ---------------
* 16 bytes 1024 bytes
* 24 bytes 512 bytes
* 32 bytes 2048 bytes
*
* Coding units are grouped into paging tiles. AFRC buffer dimensions must be aligned
* to a multiple of the paging tile dimensions.
* The dimensions of each paging tile depend on whether the buffer is optimised for
* scanline (SCAN layout) or rotated (ROT layout) access.
*
* Layout Paging Tile Width Paging Tile Height
* ------ ----------------- ------------------
* SCAN 16 coding units 4 coding units
* ROT 8 coding units 8 coding units

* struct drm_mode_fb_cmd2 - Frame-buffer metadata.
*
* This struct holds frame-buffer metadata. There are two ways to use it:
*
* - User-space can fill this struct and perform a &DRM_IOCTL_MODE_ADDFB2
* 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
* offset is common, and a zero modifier is &DRM_FORMAT_MOD_LINEAR).

* 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

* and backward compatibility, is to use a list of optional structs 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 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 {

* .name = ...,
* };
* struct i915_user_extension ext1 {
* .next_extension = (uintptr_t)&ext2,

* };
*

* 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 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

* 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)
* contain I915_MEMORY_CLASS_DEVICE then the object will be allocated and
* 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
* everything at creation time, whilst also making it immutable, on discrete

* DOC: Virtual Engine uAPI
*
* Virtual engine is a concept where userspace is able to configure a set of
* physical engines, submit a batch buffer, and let the driver execute it on any
* engine from the set as it sees fit.
*
* This is primarily useful on parts which have multiple instances of a same
* class engine, like for example GT3+ Skylake parts with their two VCS engines.
*
* For instance userspace can enumerate all engines of a certain class using the
* previously described `Engine Discovery uAPI`_. After that userspace can
* create a GEM context with a placeholder slot for the virtual engine (using
* `I915_ENGINE_CLASS_INVALID` and `I915_ENGINE_CLASS_INVALID_NONE` for class
* and instance respectively) and finally using the
* `I915_CONTEXT_ENGINES_EXT_LOAD_BALANCE` extension place a virtual engine in
* the same reserved slot.
*
* Example of creating a virtual engine and submitting a batch buffer to it:
*
* .. code-block:: C
*
* I915_DEFINE_CONTEXT_ENGINES_LOAD_BALANCE(virtual, 2) = {
* .base.name = I915_CONTEXT_ENGINES_EXT_LOAD_BALANCE,
* .engine_index = 0, // Place this virtual engine into engine map slot 0
* .num_siblings = 2,
* .engines = { { I915_ENGINE_CLASS_VIDEO, 0 },
* { I915_ENGINE_CLASS_VIDEO, 1 }, },
* };

/**
* 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.
*
* .. code-block:: none
*
* Examples syntax:
* CS[X] = generic engine of same class, logical instance X
* INVALID = I915_ENGINE_CLASS_INVALID, I915_ENGINE_CLASS_INVALID_NONE
*
* Example 1 pseudo code:
* set_engines(INVALID)
* set_parallel(engine_index=0, width=2, num_siblings=1,
* engines=CS[0],CS[1])
*
* Results in the following valid placement:
* CS[0], CS[1]
*
* Example 2 pseudo code:
* set_engines(INVALID)
* set_parallel(engine_index=0, width=2, num_siblings=2,
* engines=CS[0],CS[2],CS[1],CS[3])
*
* 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
* engines thereby making a 2D array. However, there are bonds tying the
* entries together and placing restrictions on how they can be scheduled.
* Specifically, the scheduler can choose only vertical columns from the 2D
* array. That is, CS[0] is bonded to CS[1] and CS[2] to CS[3]. So if the
* scheduler wants to submit to CS[0], it must also choose CS[1] and vice
* versa. Same for CS[2] requires also using CS[3].
* VE[0] = CS[0], CS[2]
* VE[1] = CS[1], CS[3]
*
* Example 3 pseudo code:
* set_engines(INVALID)
* set_parallel(engine_index=0, width=2, num_siblings=2,
* engines=CS[0],CS[1],CS[1],CS[3])
*
* Results in the following valid and invalid placements:
* CS[0], CS[1]
* CS[1], CS[3] - Not logically contiguous, return -EINVAL

/**
* DOC: Context Engine Map uAPI
*
* Context engine map is a new way of addressing engines when submitting batch-
* buffers, replacing the existing way of using identifiers like `I915_EXEC_BLT`
* inside the flags field of `struct drm_i915_gem_execbuffer2`.
*
* To use it created GEM contexts need to be configured with a list of engines
* the user is intending to submit to. This is accomplished using the
* `I915_CONTEXT_PARAM_ENGINES` parameter and `struct
* i915_context_param_engines`.
*
* For such contexts the `I915_EXEC_RING_MASK` field becomes an index into the
* configured map.
*
* Example of creating such context and submitting against it:
*
* .. code-block:: C
*
* I915_DEFINE_CONTEXT_PARAM_ENGINES(engines, 2) = {
* .engines = { { I915_ENGINE_CLASS_RENDER, 0 },

*
* // We have now created a GEM context with two engines in the map:
* // Index 0 points to rcs0 while index 1 points to bcs0. Other engines
* // will not be accessible from this context.
*
* ...

* DOC: Engine Discovery uAPI
*
* Engine discovery uAPI is a way of enumerating physical engines present in a

* way of using `DRM_IOCTL_I915_GETPARAM` and engine identifiers like
* `I915_PARAM_HAS_BLT`.
*
* The need for this interface came starting with Icelake and newer GPUs, which
* started to establish a pattern of having multiple engines of a same class,
* where not all instances were always completely functionally equivalent.
*
* Entry point for this uapi is `DRM_IOCTL_I915_QUERY` with the
* `DRM_I915_QUERY_ENGINE_INFO` as the queried item id.
*
* Example for getting the list of engines:
*
* .. code-block:: C
*

* struct drm_i915_query_item item = {
* .query_id = DRM_I915_QUERY_ENGINE_INFO;

* .items_ptr = (uintptr_t)&item,
* };

* // First query the size of the blob we need, this needs to be large
* // enough to hold our array of engines. The kernel will fill out the

* // querying in one pass, in which case item.length should contain the
* // length of the provided buffer.
* err = ioctl(fd, DRM_IOCTL_I915_QUERY, &query);
* if (err) ...
*
* info = calloc(1, item.length);
* // Now that we allocated the required number of bytes, we call the ioctl
* // again, this time with the data_ptr pointing to our newly allocated
* // blob, which the kernel can then populate with info on all engines.
* item.data_ptr = (uintptr_t)&info,
