[Mesa-dev] [PATCH 3/3] radv: always initialize DCC metadata to 0xFFFFFFFF

[Samuel Pitoiset]

Not sure where the magic 0x20202020 value comes from but
it's used since a while. AMDVLK also always initializes to
0xFFFFFFFF.

When DCC for MSAA textures is enabled in my experimental
branch, this appears to fix some CTS tests.

No regressions on Polaris.
