2016-03-02drm/amdgpu/pm: update current crtc info after setting the powerstateAlex Deucher1-3/+3
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.

2016-02-22drm/amdgpu/pm: adjust display configuration after powerstateAlex Deucher1-2/+3
set_power_state defaults to no displays, so we need to update the display configuration after setting up the powerstate on the first call. In most cases this is not an issue since ends up getting called multiple times at any given modeset and the proper order is achieved in the display changed handling at the top of the function.

2015-10-19drm/amdgpu/dpm: don't add pwm attributes if DPM is disabledAlex Deucher1-2/+6
PWM fan control is only available with DPM. There is no non-DPM support on amdgpu, so we should never get a crash here because the sysfs nodes would never be created in the first place. Add the check just in case to be on the safe side. Signed-off-by: Alex Deucher <[email protected]>
2015-08-17drm/amdgpu: don't grab dev->struct_mutex in pm functionsDaniel Vetter1-2/+0
Similar to radeon, except that amdgpu doesn't even use struct_mutex to protect anything like the shared z buffer (sane gpu architecture, yay!). And the code already grabs the globa adev->ring_lock, so this code can't race with itself. Which makes struct_mutex completely redundnant. Remove it.
