2017-02-21drm/amdgpu: refuse to reserve io mem for split VRAM buffersNicolai Hähnle
When the fast blit path fails while attempting to move a buffer from RAM to VRAM, we fall back to a CPU-based memcpy that cannot handle split VRAM buffers. Instead of crashing, simply fail the buffer move. Ideally, we would teach TTM about split buffers so that the fallback still works in this case, but that is quite involved. So for now, apply the simplest possible fix.

2017-01-27drm/amd/amdgpu: move eviction counting to amdgpu_bo_move_notifyNicolai Hähnle
This catches evictions of shadow page tables from the GART. Since shadow page tables are always stored in system memory, amdgpu_bo_move is never called for them. This fixes a crash during command submission that occurs when only a shadow page table and no other BOs were evicted since the last submission.
