[Mesa-dev] [PATCH v2 03/14] etnaviv: rs: add support for multi layer formats

Tue May 1 14:48:32 UTC 2018


The binary blob driver supports 'multi layer' formats. For
instance: gcvSURF_A16B16G16R16F_2_A8R8G8B8
                     < format >_n_< base format >

This defines what base format we can use for RS.
