Hi
This post and this AMD guide helped me to install the Rocm drivers and enable OpenCL for my RX6600. I’m a noob with linux and I know just few commands so asked deepseek not to guide me but the commands I need to understand what is installed and what is not.
clinfo
glxinfo | grep "OpenGL renderer"
lsmod | grep amdgpu
sudo usermod -aG render,video $USER
clinfo | grep -A5 "Platform Name.*AMD"
rocminfo | grep -A4 "Agent.*GPU"
The performance with OpenCL enabled has been quite noticeable in my case, in general, and particularly with diffuse and sharpen and using zooming.
Good luck.
