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.

drm/amdgpu: Create generic DF struct in adev 2020-01-14T15:18:41+00:00 Joseph Greathouse Joseph.Greathouse@amd.com 2020-01-14T15:05:21+00:00 bdf84a80e0ce5f60f4f41a27b4cf74bcfabcea56 The only data fabric information the adev struct currently contains is a function pointer table. In the near future, we will be adding some cached DF information into adev. As such, this patch creates a new amdgpu_df struct for adev. Right now, it only containst the old function pointer table, but new stuff will be added soon.

This interface will remove sysfs file of df_cntr_avail function. The old behavior only create sysfs of df_cntr_avail in sw_init, but never remove it for lack of sw_fini interface.
