[PATCH 3/3] drm/amdgpu: add xgmi perfmons for arcturus

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add xgmi perfmons for Arcturus.

Signed-off-by: Jonathan Kim <Jonathan.Kim@xxxxxxx>

v3: Align with patch 2 streamlining perf types versus event config types.
v2: Resend for re-review with alignment for v3 in patch 2.
