Created attachment 126237 [details] [review] Update active VRAM size when turning DMA on/off Does this patch fix the problem? (In reply to Michel Dänzer from comment #5) > Created attachment 126237 [details] [review] [review] > Update active VRAM size when turning DMA on/off > > Does this patch fix the problem? It helped in my case - FPS in Heaven increased from 1 to 15 and VRAM usage was optimal. Michael yes, it fix the problem. VM-errors are still making some noise but i think it's another problem. thx *Michel it's embarrassing |

Created attachment 126201 [details] screenshot from unigine-heaven Hi, I've tried amdgpu driver for SI and GL apps run much slower than for radeon. Unigine-Heaven drops from 20 fps to 8 fps VRAM usage ~ 200MB requested VRAM ~500MB GTT usage ~ 500MB Look at the screenshot for more. drm-next-4.9-wip: 48fad3aff638c7bc16656e31047f689aa44020a1 xorg-git mesa-git:98f734e llvm-svn:280612 libdrm:4462303 + 2 patches for SI support from amd-gfx's list I used unigine-heaven benchmark for first shot but more apps in affected: Alien Isolation Shadow of Mordor Bioshock Infinite Metro 2033 Redux XCOM The Witcher 2 xonotic (for quality "low" performance is normal) In fact only glxgears, lightsmark, gputest(all),openarena are not affected :) In any case VRAM-usage isn't raised over a 250MB but dmesg & xorg logs are different for each games, I will try update the logs later. I've tested it with dpm=1, but dpm=0 makes nothing.
