Upon review it was determined (correctly) that the docs say to use LRI. The issue is there are times where we want to do a synchronous write (GPU reset). I've tested this, and it works. I've verified with as many people as possible that it should work. This should fix the failing reset problems. Signed-off-by: Ben Widawsky Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
