[Mesa-dev] [PATCH v3 4/8] intel/isl: Allow multisampling with ISL_FORMAT_HiZ

2016-09-27 Thread Jason Ekstrand
HiZ buffers can be multisampled and, on Broadwell and earlier, simply using interleaved multisampling with a compression block size of 8x4 samples yields the correct HiZ surface size calculations. Unfortunately, choose_msaa_layout was rejecting multisampled HiZ buffers because of format checks. N
