Created attachment 107544 [details] [review] drm/radeon: Try placing NO_CPU_ACCESS BOs outside of CPU accessible VRAM
Please try current Mesa with no patches except for the two I just attached, plus this kernel patch together with the previous kernel patch.
With these it's better but still a bad. There are still pauses but they are a bit shorter, the start time without intervention is still around 2min. Start time on a good is around 1 min (assuming first run or mem caches flushed).
Hud wise - pic to follow the vram req/used match well, but the gtt is still different from a good.
On the upside - Unigine Valley is the best I've ever seen it - way better than what I've called as good in the past.
