* The reason is that for Gralloc 0.3 there are very
|
|
* few usage flags we have at our disposal.
|
|
*
|
|
* The overlapping is handled by processing the definitions

|
*
|
|
* MALI_GRALLOC_USAGE_YUV_CONF are only for YUV formats and clients
|
|
* using MALI_GRALLOC_USAGE_NO_AFBC must never allocate YUV formats.
|
|
* The latter is strictly enforced and allocations will fail.
|
|
*
|
|
* MALI_GRALLOC_USAGE_AFBC_PADDING is only valid if MALI_GRALLOC_USAGE_NO_AFBC
|
|
* is not present.
