/* AFBC supports a number of configurable modes. Relevant to us is block size
* (16x16 or 32x8), storage modifiers (SPARSE, SPLIT), and the YUV-like
* colourspace transform (YTR). 16x16 SPARSE mode is always used. SPLIT mode
* could be enabled via the hreg_block_split register, but is not currently
* handled. The colourspace transform is implicitly always assumed by the
* decoder, so consumers must use this transform as well.
*
* Failure to match modifiers will cause errors displaying AFBC buffers
* produced by conformant AFBC producers, including Mesa.
