Hi, This series adds partial support for DCC with MSAA textures. Currently, only 2x samples are supported and only on VI. This is because 4x and 8x samples currently fail. It's actually more complicated than expected but I think it's better to merge the code incrementally.
DCC for MSAA textures can be enabled with RADV_PERFTEST=dccmsaa. No CTS changes both with/without that option. I will improve the support step by step. Please review, Thanks!
