|
||||
* 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.
