--- Comment #48 from Christian König deathsimple@vodafone.de --- (In reply to Nicola Mori from comment #47)
Thanks for the clarification, Christian. Could it also impact other cases, e.g. a desktop environment with hardware accelerated visual effects?
Not really, that is way to less load to cause any real trouble. 3D games on the other hand are a different story.
Given the comment by Alex about the possibly buggy UVD1 hardware semaphores, the overall satisfactory performance of the patch and the old hardware affected by the bug I would guess that this patch likely is the final fix for this bug. If so, when will it be mainlined (approx.)?
Alex merged it into hist drm-fixes-4.1 branch and I put a CC stable on it. So if everything works well it will show up in 4.1 and is then backported to the stable kernel versions used by distributions.
