/**
|
|
* 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`

|
|
* AFRC is a proprietary fixed rate image compression protocol and format,
|
|
* designed to provide guaranteed bandwidth and memory footprint
|
|
* reductions in graphics and media use-cases.
|
|
*
|
|
* 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.

* 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
