Bug ID: 97593
Summary: [amdgpu SI] low performace, low (about 1/4) VRAM usage
Product: DRI
Version: DRI git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: arek.rusi@gmail.com

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.

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
