[VIM3 GPU drivers]

I understand that, my original question was about using the GPU for OpenCL applications

[VIM3 GPU drivers]

I'd like to use GPU OpenCL acceleration (afaik OpenCL on NPU isn't supported at all for now?) on headless armbian and I'm getting "No devices found in platform" in clinfo.

Could you clarify whether armbian has support for this and I'm missing something (kernel flags? userspace driver? some kinda nonfree blob?), or there's no support and I should move onto another distro? Thanks
