Hello @tooz, I tried the commands you suggested to check the GPU loading and usage on my Tinker Board 2/2S. The results are as follows: linaro@linaro-alip:~$ cat /sys/devices/platform/ff9a0000.gpu/utilisation 0 linaro@linaro-alip:~$ cat /sys/devices/platform/ff9a0000.gpu/devfreq/ff9a0000.gpu/load 0@800000000Hz Could you provide further guidance on what these results indicate regarding the Rockchip driver issue and any additional steps I might need to take to resolve it? Thank you for your help!!

Hello everyone, I am currently using a Tinker Board 2/2S with Debian 11 (kernel 5.10) v3.0.6 and it appears that the Rockchip driver is not loading properly. When I run glxinfo | grep "OpenGL", I encounter multiple libGL errors related to the failure to create a DRI screen and to load the Rockchip driver. Consequently, it seems to fall back to software rendering with llvmpipe. Here is the output I received: linaro@linaro-alip:~$ glxinfo | grep "OpenGL" libGL error: failed to create dri screen libGL error: failed to load driver: rockchip libGL error: failed to create dri screen libGL error: failed to load driver: rockchip OpenGL vendor string: Mesa/X.org OpenGL renderer string: llvmpipe (LLVM 11.0.1, 128 bits) OpenGL core profile version string: 4.5 (Core Profile) Mesa 20.3.5 OpenGL core profile shading language version string: 4.50 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.1 Mesa 20.3.5 OpenGL shading language version string: 1.40 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.2 Mesa 20.3.5 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 OpenGL ES profile extensions: Could anyone advise on the necessary steps to ensure the Rockchip driver loads correctly? Any guidance or suggestions would be greatly appreciated. Thank you in advance for your assistance.
