Rewrite ComfyUI.md to match reality: comfyui-rocm:gfx1151 built from
Containerfile.comfyui on AMD's gfx1151 base, device passthrough, video group
only (render is unmappable in rootless), data under /home/dank/comfyui-data,
boot-persistent via a user systemd unit. Mark research 'way 1' as applied and
update the repo-consequence section (the CPU config is no longer the default).
Live-verified on Dankclaw 2026-08-14:
- official rocm/comfyui image is built PYTORCH_ROCM_ARCH=gfx942;gfx950
(datacenter only) -> torch.cuda.is_available() False on gfx1151
- AMD gfx1151-tagged PyTorch build (rocm/vllm:...gfx1151...pytorch_2.9.1)
-> avail True, Radeon 8060S, cap (11,5); needs /dev/kfd + /dev/dri
- torch.backends.vulkan is compiled out of standard wheels; no ComfyUI
--vulkan flag exists; Vulkan is a dead end for ComfyUI
- Lemonade Server does image gen via wrapped stable-diffusion.cpp, whose
HIP kernels include gfx1151 -> works where ComfyUI's torch cannot
New pages: ComfyUI ROCm and Vulkan, Lemonade and sd.cpp; ComfyUI.md
qualified; compose stays --cpu until a gfx1151-enabled torch image is built
