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=20
Look at the screenshot for more.

drm-next-4.9-wip: 48fad3aff638c7bc16656e31047f689aa44020a1=20
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)=20
In fact only glxgears, lightsmark, gputest(all),openarena are not affected =
:)=20

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=3D1, but dpm=3D0 makes nothing.
