On Fallout4, enabling HIZ_CCS_WT compression for D16_UNORM format regress the performance by 2%, in order to avoid that disable compression via driconf option. The experiment showed that, running Fallout4 with HIZ performs better than HIZ_CCS and HIZ_CCS_WT. Reason behind that is the benchmark uses the depth pass with D16_UNORM surfaces format which fills the L3 cache and next pass doesn't make use of it where we end up clearing cache. v2: - Don't add conditional check in isl (Nanley, Jason) - Move disable_d16unorm_compression flag to instance (Lionel) - Use plane_format.isl_format (Nanley) v3: - Add more descriptive comment (Marcin Ślusarz) Signed-off-by: Sagar Ghuge <sagar.ghuge@intel.com> Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Part-of: <!6734>
