This is a fork of crystian/ComfyUI-Crystools with added AMD GPU monitoring support on Linux.
All original features are preserved. NVIDIA users are unaffected.
The general/gpu.py file has been rewritten to support AMD GPUs on Linux using a multi-backend fallback system:
| Priority | Backend | Requires | Provides |
|---|---|---|---|
| 1 | pynvml | NVIDIA driver | GPU%, VRAM, Temp |
| 2 | pyrsmi | Full ROCm stack | GPU%, VRAM, Temp |
| 3 | pyamdgpuinfo | amdgpu kernel driver | GPU%, VRAM, Temp |
| 4 | sysfs fallback | nothing extra | GPU%, VRAM, Temp |
| 5 | jtop | Jetson only | GPU%, VRAM, Temp |
The sysfs fallback reads directly from /sys/class/drm — it works out of the box with any AMD card that has the amdgpu kernel driver, no extra packages needed.
Search for crystools and install. Then replace general/gpu.py with the one from this fork.
cd ComfyUI/custom_nodes
git clone https://github.com/ProOrNoob/ComfyUI-Crystools.git ComfyUI-Crystools
cd ComfyUI-Crystools
pip install -r requirements.txt# Provides more accurate GPU utilization (requires only amdgpu driver, not full ROCm)
pip install pyamdgpuinfo
# Full ROCm SMI (requires ROCm to be installed)
pip install pyrsmi- AMD RX 6600 (RDNA2 / gfx1032)
- ROCm 7.2 / Debian Linux
- Crystools v1.27.4
GPU%, VRAM, and Temperature visible in the ComfyUI resource monitor bar — same as NVIDIA users have always had.
All credit for the original project goes to crystian.
This fork only adds AMD Linux support on top of the existing codebase.
