drm/amdgpu: Match TC hash settings to DF settings (v2)

2020-01-14T15:18:58+00:00

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 Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Create generic DF struct in adev

2020-01-14T15:18:41+00:00

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.

drm/amd/amdgpu: add sw_fini interface for df_funcs

2019-09-13T22:42:15+00:00

add sw_fini interface of df_funcs. 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. With this,driver will report create sysfs fail when it's loaded for the second time.
