Comment # 3 on bug 1204866 from Stefan Dirsch

Just verified that older Mesa versions are not affected by this (like Mesa
21.2.4 on Leap 15.4).  "radv" device driver specific settings 
00-radv-defaults.conf were splitted out of 00-mesa-defaults.conf.

    radv,drirc: move RADV workarounds to 00-radv-defaults.conf

    Because we have to maintain two different packages of Mesa, one
    specific to RADV and another one for RadeonSI and such, it's a bit
    annoying to have to synchronize the drirc entries. Currently, only our
    Mesa package installs 00-mesa-defaults.conf which means we have to
    backport the drirc RADV changes.

    This splits 00-mesa-defaults.conf in two to move the drirc RADV entries
    to src/amd/vulkan/00-radv-defaults.conf. Meson will install the file
    only if RADV is built.

    There is still a caveat for common drirc workarounds like for WSI but
    they are rare enough and we could still duplicate them if needed.
