In the current series of patches, we are trying to add support for AFBC modifiers in malidp. AFBC modifiers adds some constraints to framebuffer size, alignment, pitch, formats, etc. Here we are trying to add support for one combination of AFBC modifier ie AFBC_FORMAT_MOD_BLOCK_SIZE_16x16 | AFBC_FORMAT_MOD_SPARSE | AFBC_FORMAT_MOD_YTR. In future, we intend to add support for more combination of AFBC modifiers. Currently, we are trying to enable a basic support of AFBC in malidp.
Ayan Kumar Halder (4): drm/arm/malidp: Add modifier definitions for describing Arm Framebuffer Compression (AFBC). drm/arm/malidp: Implemented the size validation for AFBC framebuffers drm/arm/malidp: Set the AFBC register bits if the framebuffer has AFBC modifier drm/arm/malidp: Added support for AFBC modifiers for all layers except DE_SMART
