linux-stable.git/drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c, branch linux-4.5.y Linux kernel stable tree drm/amdgpu/pm: update current crtc info after setting the powerstate 2016-03-02T16:01:20+00:00 Alex Deucher alexander.deucher@amd.com 2016-02-24T22:18:25+00:00 eda1d1cf8d18383f19cd2b752f786120efa4768f On CI, we need to see if the number of crtcs changes to determine whether or not we need to upload the mclk table again. In practice we don't currently upload the mclk table again after the initial load. The only reason you would would be to add new states, e.g., for arbitrary mclk setting which is not currently supported.
