(In reply to Alex Deucher from comment #7) > Can you bisect to figure out what commit broke things for you? Okay, here is the result from bisect: b92c628712ed3a1cf5d4a144290e8ffc170bf51e is the first bad commit commit b92c628712ed3a1cf5d4a144290e8ffc170bf51e Author: Rex Zhu <Rex.Zhu@amd.com> Date: Tue Jun 5 13:06:11 2018 +0800 drm/amd/pp: Unify powergate_uvd/vce/mmhub to set_powergating_by_smu Some HW ip blocks need call SMU to enter/leave power gate state. So export common set_powergating_by_smu interface. 1. keep consistent with set_clockgating_by_smu 2. scales easily to powergate other ip(gfx) if necessary Reviewed-by: Evan Quan <evan.quan@amd.com> Signed-off-by: Rex Zhu <Rex.Zhu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> :040000 040000 cf80741fafed463d93a0d41d85f267ff8c3859ca 2daca62d7af472048be8e0911c39e9a26fe376c0 M drivers Let me know if there's anything more I can do to help. I'll take a look at the code but like I said I'm not a kernel developer so it's unlikely I'll understand it or be able to fix it.
