On Arcturus, data fabric hashing is set by the VBIOS, and affects which addresses map to which memory channels. The gfx core's caches also need to know this mapping, but the hash settings for these these caches is set by the driver. This change queries the DF to understand how the VBIOS configured DF, then matches the TC hash configuration bits to do the same thing. v2: squash in warning fix Signed-off-by: Joseph Greathouse <Joseph.Greathouse@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
