We end up reading the interrupt register for HPD5, and then writing it to HPD6 which on systems without anything using HPD5 results in permanently disabling hotplug on one of the display outputs after the first time we acknowledge a hotplug interrupt from the GPU.

2017-05-24drm/i915/gvt: clean up unsubmited workloads before destroying kmem cacheChangbin Du1-10/+20
This is to fix a memory leak issue caused by unfreed gvtg workload objects. Walk through the workload list and free all of the remained workloads before destroying kmem cache.

2017-05-23drm/gma500/psb: Actually use VBT mode when it is foundPatrik Jakobsson1-7/+11
With LVDS we were incorrectly picking the pre-programmed mode instead of the prefered mode provided by VBT. Make sure we pick the VBT mode if one is provided. It is likely that the mode read-out code is still wrong but this patch fixes the immediate problem on most machines.

The dead code removal left two unused variables: drivers/gpu/drm/gma500/mdfld_tpo_vid.c: In function 'tpo_vid_get_config_mode': drivers/gpu/drm/gma500/mdfld_tpo_vid.c:34:31: error: unused variable 'ti' [-Werror=unused-variable] This removes them as well.

2017-05-23drm/i915/guc: Skip port assign on first iteration of GuC dequeueMichał Winiarski1-1/+2
If port[0] is occupied and we're trying to dequeue request from different context, we will inevitably hit BUG_ON in port_assign. Let's skip it - similar to what we're doing in execlists counterpart.
