^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   7) AFBC is a proprietary lossless image compression protocol and format.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   8) It provides fine-grained random access and minimizes the amount of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300   9) data transferred between IP blocks.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  11) AFBC can be enabled on drivers which support it via use of the AFBC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  12) format modifiers defined in drm_fourcc.h. See DRM_FORMAT_MOD_ARM_AFBC(*).

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  14) All users of the AFBC modifiers must follow the usage guidelines laid

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  20) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  21) AFBC streams can contain several components - where a component
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  22) corresponds to a color channel (i.e. R, G, B, X, A, Y, Cb, Cr).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  23) The assignment of input/output color channels must be consistent
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  24) between the encoder and the decoder for correct operation, otherwise
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  25) the consumer will interpret the decoded data incorrectly.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  26) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  27) Furthermore, when the lossless colorspace transform is used
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  28) (AFBC_FORMAT_MOD_YTR, which should be enabled for RGB buffers for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  29) maximum compression efficiency), the component order must be:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  30) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  31)  * Component 0: R
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  32)  * Component 1: G
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  33)  * Component 2: B
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  34) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  35) The component ordering is communicated via the fourcc code in the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  36) fourcc:modifier pair. In general, component '0' is considered to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  37) reside in the least-significant bits of the corresponding linear
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  38) format. For example, COMP(bits):

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  59) In AFBC, 'X' components are not treated any differently from any other
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  60) component. Therefore, an AFBC buffer with fourcc DRM_FORMAT_XBGR8888
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  61) encodes with 4 components, like so:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  62) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  63)  * DRM_FORMAT_XBGR8888

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  67)    * Component 2: B(8)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  68)    * Component 3: X(8)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  69) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  70) Please note, however, that the inclusion of a "wasted" 'X' channel is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  71) bad for compression efficiency, and so it's recommended to avoid
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  72) formats containing 'X' bits. If a fourth component is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  73) required/expected by the encoder/decoder, then it is recommended to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  74) instead use an equivalent format with alpha, setting all alpha bits to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  75) '1'. If there is no requirement for a fourth component, then a format
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  76) which doesn't include alpha can be used, e.g. DRM_FORMAT_BGR888.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  78) Number of Planes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  79) ================
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  80) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  81) Formats which are typically multi-planar in linear layouts (e.g. YUV
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  82) 420), can be encoded into one, or multiple, AFBC planes. As with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  83) component order, the encoder and decoder must agree about the number
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  84) of planes in order to correctly decode the buffer. The fourcc code is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  85) used to determine the number of encoded planes in an AFBC buffer,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  86) matching the number of planes for the linear (unmodified) format.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  87) Within each plane, the component ordering also follows the fourcc
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  88) code:
