Code Review
This pull request introduces a new version of the fused DeepSeek V4 kernel (V2) that utilizes one block per token to improve performance for larger token counts, along with logic to switch between kernels based on a 1024-token threshold. Feedback indicates that removing the 'grid' variable will cause compilation errors on ROCm platforms. Furthermore, the reviewer pointed out that the updated unit tests use a token count below the threshold, meaning the new V2 kernel path remains untested; increasing the test token count to at least 1024 was recommended.

We don't need to launch this grid if we are doing one CTA per token?

For low batch size, it is still beneficial to have one CTA per (token, head) pair, so this grid is still used when num_tokens_full < 1k. The "one CTA per token" path added by this PR is used for larger batch sizes

Partial rebase of PR vllm-project#42316 ("Port DeepSeek V4 FlashInfer sparse MLA kernels") onto current upstream/main, after the V4 source tree was moved to vllm/models/deepseek_v4/ (vllm-project#43039/vllm-project#43073/vllm-project#43077/vllm-project#43149) and the fused CUDA insert kernel was restructured (vllm-project#43162/vllm-project#42353). This commit lands the CSRC + low-level plumbing only: - csrc/fused_deepseek_v4_qnorm_rope_kv_insert_kernel.cu: keep upstream's per-slot padded-Q kernel for FlashMLA unchanged; append a sibling fusedDeepseekV4FullCacheKernel<scalar_t_in, STORE_Q_FP8, STORE_KV_FP8> for the FlashInfer V4 path. Writes a contiguous 512-wide K-cache row per token (BF16 or per-tensor FP8 E4M3) with no Q padding. Adds packFp8E4M3x16 helper and BF16 / FP8 launchers. - csrc/ops.h + csrc/torch_bindings.cpp: declare and register two new Torch ops, fused_deepseek_v4_qnorm_rope_kv_rope_full_cache_bf16_insert and fused_deepseek_v4_qnorm_rope_kv_rope_full_cache_fp8_insert. - vllm/config/cache.py: add "fp8_per_tensor" to CacheDType. - vllm/utils/torch_utils.py: map fp8_per_tensor -> torch.float8_e4m3fn. - vllm/v1/attention/backends/registry.py: add V4_FLASHMLA_SPARSE and V4_FLASHINFER_MLA_SPARSE entries so --attention-backend can select the V4 sparse impl explicitly (target classes added later). - docs/design/attention_backends.md: auto-regenerated by the attention-backend-docs pre-commit hook for V4_FLASHMLA_SPARSE. Build: cmake --build --preset release --target install -> exit 0. Smoke test confirms both new ops registered on torch.ops._C. The Python-side wiring (DeepseekV4FlashInferMLASparseImpl, attention.py dispatch, compressor full-cache branch, sparse SWA dtype softening, FlashInfer launcher helpers, kernel warmup, tests, and the _select_v4_sparse_impl refactor that lets the new --attention-backend flag win) follows in later commits. AI assistance: Claude Code (Opus 4.7) drafted the merge mechanically; not yet manually reviewed end-to-end. Do not merge until verified.
