The misunderstanding here is that I am referring to getting Linux GPGPU to work in the first place, not porting the code itself. Presumably they are suggesting that one of us Linux weirdos who already have gotten ROCm and/or CUDA working could do it with relative ease. That said, I have not attempted to verify the veracity of that assertion, but I think it's what they meant. Though even if they could just do it, and have everything they need to do it, that doesn't mean they're lying. It really could just not be a priority.
