So unfortunately I don’t think ROCM supports the deck’s APU, and it’s too different for it to work by faking that it’s a different GPU.

You can still do stable diffusion in CPU mode, but that will take 5-20 min per image (vs 7 seconds per image on my desktop’s 6600 XT).

Overall it’s not worth it unfortunately. As an alternative you might look into running stable diffusion through Google colab, which is a good way to get custom generation going for free.
