Support SageAttentionV3 on Other Blackwell GPUs

[Ash-Zheng]

Hi,

I'm interested in using SageAttentionV3 but noticed that it currently only supports RTX 5090 GPUs with SM120 architecture.

Are there any plans to extend compatibility to SM100 GPUs, specifically the B200 and GB200 series?

I'd appreciate any information about the roadmap or timeline for this support.

Thank you!

I think the card must have FP4 support in order to work with Sage Attention 3
