Hi Gerd,
I'm using glmark2 to test virtio-gpu on AMDGPU, but the result is
unsatisfactory.
GPU: AMD Radeon Pro WX 5100
Host OS: CentOS Linux release 7.7.1908 (AltArch)
--QEMU: 4.0.0
--linux kernel 4.18
--mesa 18.3
--virglrenderer
--spice server 0.14.2
--spice-gtk3-0.35
--libepoxy 1.5.2
Guest OS: CentOS Linux release 7.7.1908 (AltArch)
--linux kernel 4.18
--mesa 18.3
--xorg server 1.20
TestSuit: glmark2
Host result:
glmark2 Score: 10043
Single Guest result:
glmark2 Score: 2209
Multi Guest result:
Guest1: glmark2 Score: 1136
Guest2: glmark2 Score: 1231
Guest3: glmark2 Score: 1282
Guest4: glmark2 Score: 1175
Guest5: glmark2 Score: 1398
It seems the whole performance of multi-guests is better than single
guest, but each one has lower performance. I change 'ctrl_vq' from 256
to 1024, but has little effect. I wonder the result is normal or
abnormal? And which is the bottleneck? I'm appreciated for you help.
thanks,
Jun
