🚀 The feature, motivation and pitch

Ideally, vLLM could provide a generic Triton-based fallback implementation for DeepSeek V4. This would allow unsupported architectures such as SM89/SM120 to run DeepSeek V4 even when highly optimized vendor-specific kernels like DeepGEMM or FlashMLA are unavailable. The goal is not necessarily to match the peak performance of DeepGEMM / FlashMLA, but to provide a portable and compatible execution path across more NVIDIA GPU architectures.

I am not sure whether there is broader demand in the community for a generic Triton-based implementation, but I think it could be useful as a compatibility fallback for newer or less commonly supported NVIDIA architectures.
