Please describe your issue below:

Is OpenCL (for GPU) supported on mainline kernel? I’m getting errors running clinfo and opencl applications. What packages and/or kernel modules might I be missing?

Post a console log of your issue below:

Silly question… did you run it as root ? (sudo) ?

I am using the debian11 build and it seems its all there. This is what I done to get ARMNN working with OpenCL (Note - I used non GUI version … debian11 minimal)

   wget -c "https://github.com/ARM-software/armnn/releases/download/v23.02/ArmNN-linux-aarch64.tar.gz"
   mkdir /lib/armnn
   tar -xf ArmNN*.tar.gz -C /lib/armnn
   
  wget "https://dl.khadas.com/repos/vim4/pool/main/l/linux-gpu-mali-wayland/linux-gpu-mali-wayland_1.1-r37p0-202208_arm64.deb"
   dpkg -i linux-gpu-mali-wayland_1.1-r37p0-202208_arm64.deb

@RichardPar that package is for the vim4, vim3 should be utilizing a different package.
I believe this one specifically:

https://dl.khadas.com/repos/vim3/pool/main/l/linux-gpu-mali-fbdev/linux-gpu-mali-fbdev_1.5-r12p0_arm64.deb

Youre right! … sorry :smiley: I had VIM3 and VIM4 environments open … copy/pasted the wrong one :smiley:
