CUDA: requires parts (at least some libs) from NVidia which are not ported to FreeBSD. I have seen reports that at least parts of the linux parts work in the linuxulator (https://github.com/verm/freebsd-stable-diffusion). If you want to use a FreeBSD system to do that, I would suggest to use a VM with linux and give it raw access to the card. Not nice (from a FreeBSD side of things), but most probably the most pragmatic solution to get all what is needed in a easy way. ROCm: No idea. I have not seen any report about it working or even being tried. But there was at least some discussion about it: https://github.com/ROCm/ROCm/issues/138 https://github.com/ROCm/ROCm/issues/1913 Intel: Maybe. We have spirv ports in the tree, and my limited understanding is, that SPIR-V comes into play when someone wants to do GPU compute there. CCing Jan as the port maintainer for the two spirv ports. Maybe he can shed some light on this part.
