[Intel-gfx] [PATCH 4/5] drm/i915: Use RPM as the barrier for controlling user mmap access

2016-10-12 Thread Chris Wilson
We can remove the false coupling between RPM and struct mutex by the observation that we can use the RPM wakeref as the barrier around user mmap access. That is as we tear down the user's PTE atomically from within rpm suspend and then to fault in new PTE requires the rpm wakeref, means that no

2016-10-12 Thread Chris Wilson
The current meaning of whether an object has a GGTT vma is very ill-defined (and note we don't check for any partials either), it just means that at some point it was in the GGTT but it may not be now. The information we really care about here is whether it is taking up precious mappable aperture
