Greetings, I use a standard Ubuntu 20.04 focal rootfs with a mainline kernel on an IMX6Q based board and have had no issues using things like gnome desktop, glxgears, glmark2 however recently I updated the rootfs to Ubuntu 22.04 jammy using the same mainline kernel and now I see some issues. I've replicated the issue with several kernel versions including 5.4, 5.10, 5.15 and 6.0 so I would say this is not a kernel regression but something related to the graphics stack being used which I'm not very familiar with. The issues I see can be described as: - mouse cursor is incorrect (looks like a hatched square) - glxgears shows some sort of sync/jitter issue and has a fairly low framerate - glmark2 shows a some sync issues then after a few seconds results in a GPU hang My ubuntu focal image that appears to work fine has the following: gnome 3.36.5-0 xserver-xorg 1:7.7+19 xserver-xorg-core 2:1.20.13-1 xwayland 2:1.20.13-1 glmark2 2021.02 mesa-utils 8.4.0-1 GL_VENDOR: Mesa/X.org GL_RENDERER: llvmpipe (LLVM 12.0.0, 128 bits) GL_VERSION: 3.1 Mesa 21.2.6 My ubuntu jammy image that has the issues has the following: gnome-41.7-0 xserver-xorg 1:7.7+23 xserver-xorg-core 2:21.1.3-2 xwayland 2:22.1.1-1 glmark2 2021.02-0 mesa-utils 8.4.0-1 GL_VENDOR: etnaviv GL_RENDERER: Vivantte GC2000 rev 5108 GL_VERSION: 2.1 Mesa 22.0.5 Does anyone have any ideas on what might be going on here? I apologize for my lack of knowledge regarding the software layers on top of the etnaviv kernel driver being used here. Best Regards, Tim
