Unfortunately, I never managed to land the patch, but someone else did, so now we can use it. As a reminder, hardware contexts never need to be in the precious GTT aperture space - which is what is what happens with the normal bottom up allocation we do today. Doing a top down allocation increases the odds that the HW contexts can get out of the way, especially with per FD contexts as is done in full PPGTT Signed-off-by: Ben Widawsky Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
