2017-02-23drm: zte: fix static checker warning on variable 'fmt'Shawn Guo1-2/+2

2017-02-21drm/amdgpu: refuse to reserve io mem for split VRAM buffersNicolai Hähnle1-0/+3
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.

2017-02-21drm/ttm: fix use-after-free races in vm fault handlingNicolai Hähnle1-0/+12
The vm fault handler relies on the fact that the VMA owns a reference to the BO. However, once mmap_sem is released, other tasks are free to destroy the VMA, which can lead to the BO being freed. Fix two code paths where that can happen, both related to vm fault retries. Found via a lock debugging warning which flagged &bo->wu_mutex as locked while being destroyed.

There are instances (such as non-recoverable GPU page faults) where NVKM decides that a channel's context is no longer viable, and will be removed from the runlist. This commit notifies the owner of the channel when this happens, so it has the opportunity to take some kind of recovery action instead of hanging. Signed-off-by: Ben Skeggs <[email protected]>
