Feature Request: Support for SM90 (Hopper / H100) GPUs

[huyiwen]

Summary

Is there any plan to support SM90 (Hopper / H100) GPUs? Currently MSA only supports NVIDIA SM100 (compute capability 10.0), but many users have access to Hopper-based GPUs like H100/H800 which use compute capability 9.0 (sm_90).

Details

• Target GPU architecture: SM90 / Hopper (e.g., H100 SXM, H100 PCIe, H800)
• Compute capability: 9.0 (sm_90)
• Current status: Not mentioned in README, no related issues found, code directory only has fmha_sm100/

Questions

1. Is SM90 support on the roadmap?
2. If so, any estimated timeline?
3. If not, would the team accept community contributions for SM90 porting?

Thanks!
