iris: Support I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS
I tested this modifier with an x11-session of mutter and with kmscube. With mutter I was able to test the dmabuf import code and with kmscube I was able to test creating a resource with the modifier.
Dependencies:
-
Required: MR !4972 (merged) fixes texview rendering bugs made worse on gen12 due to new CCS behavior -
Required: MR !5363 (merged) fixes incorrect tracking of clear state on gen12 due to new CCS behavior -
Optional: MR !5388 (merged) fixes incorrect indirect clear color handling for blorp_copy on gen11+
