[Windows] ComfyUI-ZLUDA fails to start - compilation error with struct timeval visibility on ROCm 6.4

[dwojewod]

Custom Node Testing

• I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Expected Behavior

ComfyUI should start successfully after kernel compilation.

Actual Behavior

ComfyUI-ZLUDA fails to start during Triton kernel compilation. The process stops after compilation warnings about struct timeval visibility in Python headers.

Steps to Reproduce

Environment

OS: Windows
GPU: AMD gfx1150 (RDNA3)
ROCm: 6.4
Python: 3.11.13
Triton: 3.4.0
Package manager: StabilityMatrix
ComfyUI-ZLUDA: Installed via StabilityMatrix on 07.01.2026
