X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2ce11ac11fee594ca01608c4006b38c0c8ea37ff;p=mesa.git radv: Initialize DCC on transition from preinitialized. Looks like the decompress does not handle invalid encodings well, which happens with random memory. Of course apps should not use it with random memory, but they are allowed to .... Fixes: 44fcf58744 "radv: Disable DCC for GENERAL layout and compute transfer dest."
