Subject: radv: Disable multilayer & multilevel DCC.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bee83b26611c0a4a554aa37c59187351242e82fd;p=mesa.git

radv: Disable multilayer & multilevel DCC.

The current DCC init routine doesn't account for initializing a
single layer or level. Multilayer seems hard for small textures on
pre-GFX9 as tre metadata for the layers can be interleaved. For
GFX9 multilevel textures are a problem for similar reasons.

So just disable this for now, until we handle the texture modes
correctly.
