[Intel-gfx] [PATCH] drm/i915: Make the physical object coherent with GTT

Currently objects for which the hardware needs a contiguous physical address are allocated a shadow backing storage to satisfy the contraint. This shadow buffer is not wired into the normal obj->pages and so the physical object is incoherent with accesses via the GPU, GTT and CPU. By setting up the
