drm/amdgpu/cgs: always set reference clock in mode_info

2017-06-30T15:28:35+00:00

It's relevent regardless of whether there are displays
enabled.  Fixes garbage values for ref clock in powerplay
leading to incorrect fan speed reporting when displays
are disabled.

drm/amdgpu: fix vblank_time when displays are off

2017-06-30T13:53:50+00:00

If the displays are off, set the vblank time to max to make
sure mclk switching is enabled.  Avoid mclk getting set
to high when no displays are attached.

drm/amdgpu: Fix use of interruptible waiting

2017-04-28T21:33:09+00:00

Either in cgs functions or for callers of cgs functions:
1. The signal interrupt can affect the expected behaviour
2. There is no good mechanism to handle the corresponding error
3. There is no chance of deadlock in these single BO waiting
4. There is no clear benefit for interruptible waiting
5. Future caller of these functions might have same issue.

drm/amd/amdgpu: fix Tonga S3 resume hang on rhel6.8

2017-03-30T03:55:49+00:00

1. security firmware loading has moved to sw init, so this code
   is useless.
2. it seems that driver could not call request_firmware on
   kernel 2.6, when S3 resume. for request firmware depends on
   userspace, at this time, userspace is freeze.
