[PULL] drm-intel-fixes

[Rodrigo Vivi]

Hi Dave and Daniel,

This one looks big, but it actually includes the one I had
sent last week, but probably too late on Thursday. Sorry.

There are various fixes acummulated here around preemption,
timeslices, fences and vma unbind, mostly for GPU hangs,
and deadlocks. There's also Some display workaroudns and fixes,
including frame buffer compression fix, and a fix for DP AUX
on Tiger Lake.

This also  includes GVT with fix for arecent guest display probe
failure, and a fix for a kernel oops for older aliasing ppgtt guest.

Here goes drm-intel-fixes-2020-05-13-1:
- Handle idling during i915_gem_evict_something busy loops (Chris)
- Mark current submissions with a weak-dependency (Chris)
- Propagate errror from completed fences (Chris)
- Fixes on execlist to avoid GPU hang situation (Chris)
- Fixes couple deadlocks (Chris)
- Timeslice preemption fixes (Chris)
- Fix Display Port interrupt handling on Tiger Lake (Imre)
- Reduce debug noise around Frame Buffer Compression
+(Peter)
- Fix logic around IPC W/a for Coffee Lake and Kaby Lake
+(Sultan)
- Avoid dereferencing a dead context (Chris)

Thanks,
Rodrigo.
