Do Hopper support Deepseek V4 Flash run EP by deepep in the future?

[dingfen]

I tried to run DeepSeek V4 Flash with expert parallel with deepep version 1.2.1 and sglang 0.5.12 on H20，but I got the Error, And I found that the recipe does not mention the FP8-FP4 mixed EP running method, and I wonder if sglang will support deepep with FP4 in the future on SM90

--deepep-mode auto --trust-remote-code --watchdog-timeout 3600 --dist-timeout 3600 --speculative-attention-mode decode --moe-a2a-backend deepep

tvm.error.InternalError: Assertion error (/deepgemm/csrc/apis/../jit_kernels/impls/../heuristics/../../utils/layout.hpp:57):
ab.scalar_type() == kPackedFP4 and arch_major == 10

The Assertion says it need FP4 and SM100 simultaneously, and We expect it can run on SM90
