[Bug 101691] gfx corruption on windowed 3d-apps running on dGPU

--- Comment #37 from Michel Dänzer <michel at daenzer.net> ---
I wonder if it could be related to the caching attributes of the system memory
pages being shared between the GPUs. AFAICT the amdgpu driver should end up
treating them as non-cacheable, and correspondingly program the AMD GPU not to
participate in cache coherency protocol for them. How does the i915 driver
treat the pages of imported buffer objects?
