drm/amdgpu: return from atombios_dp_get_dpcd only when error

2016-03-02T16:01:25+00:00

In amdgpu_connector_hotplug(), we need to start DP link
training only after we have received DPCD. The function
amdgpu_atombios_dp_get_dpcd() returns non-zero value only
when an error condition is met, otherwise returns zero.
So in case the function encounters an error, we need to
skip rest of the code and return from amdgpu_connector_hotplug()
immediately. Only when we are successfull in reading DPCD
pin, we should carry on with turning-on the monitor.

drm/amdgpu/cz: remove commented out call to enable vce pg

2016-03-02T16:01:24+00:00

This code path is not currently enabled now that we properly
respect the vce pg flags, so uncomment the actual pg calls
so the code is as it should be we are eventually able to
enable vce pg.

drm/amdgpu/powerplay/cz: enable/disable vce dpm independent of vce pg

2016-03-02T16:01:24+00:00

If we don't disable it when vce is not in use, we use extra power
if vce pg is disabled.

We never ported that back to CIK, so we could run into VM faults here.

drm/amdgpu/pm: update current crtc info after setting the powerstate

2016-03-02T16:01:20+00:00

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.
