Loading Rockchip Driver on Tinker Board 2/2S with Debian 11

[aki 0]

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.

hello @aki, 

the embedded gpu uses GLES instead of GL

please use the commands below to check the gpu loading/ usage instead of glxinfo: 

cat /sys/devices/platform/ff9a0000.gpu/utilisation
cat /sys/devices/platform/ff9a0000.gpu/devfreq/ff9a0000.gpu/load

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 @aki,

linaro@linaro-alip:~$ cat /sys/devices/platform/ff9a0000.gpu/devfreq/ff9a0000.gpu/load
0@800000000Hz

the @800000000Hz here means the gpu frequency is set to 800mhz, 0 means the gpu usage = 0

is the gpu governor set to performance? 

and please use these commands to check gpu when you're running applications that might be using gpu to accelerate -- for exmaple, you can use the commands while running glmark2-es2 and the gpu usage should not be 0. if the apis you are using support gpu accelerating then it (gpu usage = 0) should not be the case
