[PATCH 0/7 v2] Improve S0ix stability

[Alex Deucher]

This series improves S0ix stability by avoiding touching
registers that should be handled as part of gfxoff.

v2: add comments in gmc code to explain why we can
skip the vm fault state setting for gfxhub.

Alex Deucher (7):
  drm/amdgpu/gmc9: don't touch gfxhub registers during S0ix
  drm/amdgpu/gmc10: don't touch gfxhub registers during S0ix
  drm/amdgpu/gmc11: don't touch gfxhub registers during S0ix
  drm/amdgpu: don't mess with SDMA clock or powergating in S0ix
  drm/amdgpu: for S0ix, skip SMDA 5.x+ suspend/resume
  Revert "drm/amdgpu: disallow gfxoff until GC IP blocks complete s2idle
    resume"
  Revert "drm/amdgpu: force exit gfxoff on sdma resume for rmb s0ix"
