CUDA kernel and fusion code for Fused Groupwise FP8-Quantized RMS Norm. This code allows to fuse RMS Norm + FP8 Quantization of the RMS Norm's output when enable_fusion==True.

Testing:

Test fused op

pytest tests/kernels/core/test_fused_quant_layernorm.py

Test fusion

pytest tests/compile/test_fusion.py

(tested with both VLLM_USE_DEEP_GEMM=1 and VLLM_USE_DEEP_GEMM=0)

Offline inference

Run with

llm = LLM(model="Qwen/Qwen3-30B-A3B-FP8",
        compilation_config=CompilationConfig(
            pass_config=PassConfig(
                enable_fusion=True,
                enable_noop=True)))

(tested with both VLLM_USE_DEEP_GEMM=1 and VLLM_USE_DEEP_GEMM=0, verified that the fused kernel is being produced)

Benchmarking:

Microbenchmark isolated op:

python benchmarks/fused_kernels/layernorm_rms_benchmarks.py

@ProExpertProg I've now observed function mismatches in fusion tests when running with deepgemm enabled on H100, so we should either add this support later of delay landing until it's fixed -- what is your opinion on this?

Figured it out now, pushed the fix :)

After this PR, Qwen3 VLs (and most likely other FP8 VLMs I guess) are failing with the following error:

...
AttributeError: 'Qwen3VLMoeConfig' object has no attribute 'intermediate_size'

which is raised at using_deepgemm checking hf_config.intermediate_size w/o proper guard.

@yeqcharlotte @meta-codesync
Guard group quant RMS norm fusion patterns on CUDA platforms
f09d137 
Summary:
Fix AMD compilation failure for DeepSeek models introduced in vllm-project#27883.

The issue was that RMSNormQuantFusionPass unconditionally creates
FusedAddRMSNormGroupQuantPattern and RMSNormGroupQuantPattern for
group quantization (GroupShape 64 and 128), but the underlying C++
operation per_token_group_fp8_quant is only available on CUDA
(wrapped in #ifndef USE_ROCM in torch_bindings.cpp).

On AMD platforms, this caused an assertion failure:
  AssertionError: unsupported quantization scheme QuantKey(f8e4m3fnuz,scale(f32,dynamic,GroupShape(row=1, col=128)),symmetric)

The fix guards the creation of group quant patterns with
current_platform.is_cuda(), matching the guard used for registering
these keys in QUANT_OPS.

Test Plan:
Waiting for this deepseek job on amd to complete: https://www.internalfb.com/vanguard/serving_test_cases/1967790977283741

Will also wait for external CI
