drm/amdgpu: refuse to reserve io mem for split VRAM buffers

2017-10-21T15:21:36+00:00

[ Upstream commit 4694335dad7357e9b3d7822ab13049014d74d8b0 ] 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.

drm/amd/amdgpu: Return error if initiating read out of range on vram

2017-07-27T22:08:02+00:00

commit 9156e723301c0a7a7def4cde820e018ce791b842 upstream. If you initiate a read that is out of the VRAM address space return ENXIO instead of 0. Reads that begin below that point will read upto the VRAM limit as before. Signed-off-by: Tom St Denis Reviewed-by: Christian König Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

mm: replace get_user_pages() write/force parameters with gup_flags

2016-10-19T15:11:43+00:00

This removes the 'write' and 'force' from get_user_pages() and replaces them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers as use of this flag can result in surprising behaviour (and hence bugs) within the mm subsystem.
