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
