2016-03-02drm/amdgpu: return from atombios_dp_get_dpcd only when errorArindam Nath1-1/+1
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.

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.

2016-02-19drm/amdgpu: Don't hang in amdgpu_flip_work_func on disabled crtc.Mario Kleiner1-3/+15
This fixes a regression introduced in Linux 4.4. This is a port of the same fix for radeon-kms in the patch "drm/radeon: Don't hang in radeon_flip_work_func on disabled crtc. (v2)" Limit the amount of time amdgpu_flip_work_func can delay programming a page flip, by both limiting the maximum amount of time per wait cycle and the maximum number of wait cycles. Continue the flip if the limit is exceeded, even if that may result in a visual or timing glitch. This is to prevent a hang of page flips, as reported in fdo bug #93746: Disconnecting a DisplayPort display in parallel to a kms pageflip getting queued can cause the following hang of page flips and thereby an unusable desktop: 1. kms pageflip ioctl() queues pageflip -> queues execution of amdgpu_flip_work_func. 2. Hotunplug of display causes the driver to DPMS OFF the unplugged display. Display engine shuts down, scanout no longer moves, but stays at its resting position at start line of vblank. 3. amdgpu_flip_work_func executes while crtc is off, and due to the non-moving scanout position, the new flip delay code introduced into Linux 4.4 by commit 8e36f9d33c13 ("drm/amdgpu: Fixup hw vblank counter/ts..") enters an infinite wait loop. 4. After reconnecting the display, the pageflip continues to hang in 3. and the display doesn't update its view of the desktop.
