Hi,
We met a problem on ubuntu17.10 for arm server with amdgpu(AMD RADEON
PRO WX7100), we use open source driver which are integrated in ubuntu17.10.
And the architecture is AArch64-linux-gnu.
we install :
apt-get install xserver-xorg xinit xfce4 and mesa-utils glmark2
we start x server :
startx
and then the monitor shows the screen and the screen is blurred(
something wrong).

And I have tried some opengl applications, the output has same
problem.(something is missing or in the wrong place.)
But in a x86_64 architecture server, with same OS. The screen output
is normal. (I check xorg\DDX\mesa\libdrm etc.all the versions are the same with
aarch64 server.)
What I have done:
1、I upgrade kernel to 4.15-rc2 ,upgrade DRM to 3.23,upgrade DDX to
1.40,upgrade mesa to 17.2.6, but the problem still exist.
2、I enable ‘shadowprimary’ option, the screen output became normal,
but the performance drop quickly――glxgears drop from 4800fps to 600fps, glmark
drop from 4300 score to 730 score.
I doubt there are something different in aarch64 and x86_64 but I
don’t know.
Any Advice or trial suggestion are welcome.
Thanks.
Rejohn.
