Take this with a pinch of salt, but the most recent ROCm release installed out of the box on my WSL2 machine and worked first time with llama.cpp. I even compiled llama.cpp from source with 0 issues. That has never happened ever in my 5+ years of having AMD GPUs. Every other time I've tried this it's either failed and required arcane workarounds, or just not worked entirely (including running on 'real' Linux).

I feel like finally they are turning the corner on software and drivers.
