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

--- Comment #44 from Ben Widawsky <ben at bwidawsk.net> ---
There is no special handling for how the GPU maps dma-buf imported objects. In
other words, it will default to LLC caching on KBL.

Provided amdgpu is flushing its contents properly though, the LLC should just
follow normal coherency snoop protocol and i915 should see the changed data.
