…port - Mirror the fmha_sm100 plan's seqused_k in the CUDA-graph-stable plan buffers; the planner allocates it per step and the kernel reads it at launch, so the captured address must not move. - Force the shared draft KV cache only for MiniMax-M3 one-model Eagle3, and reject the triton reference backend with CUDA graphs: its multi-token verify goes through the prefill builder, which cannot be captured. Drop the unreachable multi-token dense decode branch and the decode_qo_len field. - Reject NVFP4 pool pointers in the virtual attention-op pool builder instead of writing a null block-scale pointer. - Size the MSA proxy scratch from the KV cache manager's draft length, so runs without speculative decoding size by max_num_sequences. - Document why per-token seqused_k mirrors the planner (0 for an empty row) while the valid-block count is clamped to 1. - Drop the pinned cuda_graph/use_msa axes of test_nvfp4_eagle3 and list the disagg/overlap combinations explicitly; update the test lists.

In `@tensorrt_llm/_torch/attention/backends/sparse/minimax_m3/cache_manager.py`:
- Around line 193-198: Add a regression unit test for
extend_attention_op_pools_for_shared_draft_layers that passes a 3-D
pool_pointers tensor and asserts the exact NotImplementedError message, ensuring
the rejection occurs before virtual pools are created.
In `@tensorrt_llm/_torch/pyexecutor/py_executor_creator.py`:
- Around line 513-518: Add a focused regression test covering one-model
MiniMax-M3 Eagle3 with implementation="triton" and a non-None cuda_graph_config,
ensuring the executor creation path raises ValueError. Assert the complete
rejection message, while preserving the existing integration test’s
implementation="msa" setup.
In `@tests/integration/defs/accuracy/test_llm_api_pytorch.py`:
- Around line 9204-9205: Update the test setup around msa_package_available() to
also skip unless the active GPU supports SM100 or newer, before constructing the
MSA configuration. Preserve the existing package-availability skip and use the
repository’s established GPU capability detection symbols.

As a general principle, dis-agg does not accept new E2E tests. If possible, please decompose this into unit tests or replace an existing test rather than adding a new one. Thanks!

…mp decode valid blocks Review follow-ups on the consolidated MiniMax-M3 Eagle3 PR: - Remove the disaggregated arm of test_nvfp4_eagle3 (disagg does not take new end-to-end accuracy tests); test_disaggregated_serving.py is back to main. The grid is now overlap_scheduler x attention_dp. - CI runs one combination (attention_dp=False, overlap_scheduler=True, the production shape) and inherits the stage timeout; the explicit TIMEOUT (180) annotations are gone from both lists. - Clamp the decode-path valid-block counts to at least one block, matching the eager path and on_update_kv_lens.

Supersedes #16021
#16021 was the initial eagle support from Minimax-m3 side branch based on July design but many fixes are added on the side branch afterwards (#17341, #17457, #17656, #18066), so we decided to not merge #16021, which is pretty stale.
This current PR (#18872) contains the all eagle related PRs/changes in Minimax-m3 side branch. Also, I tried to minimize the changes in hot path that is not specifically for Minimax-m3 to make this PR easier to merge. Now there are only 8 lines changes in flashinfer_trtllm_gen.py and 4 lines changes in py_executor_creator.py in hot path, while all others should be contained in Minimax-m3 specific file/path.
What this PR mainly contains
Minimax-m3 Eagle performance on AgentX (tested on Minimax-m3 side branch)
It's a controlled ablation on one of Minimax-m3 AgentX submission stack: SemiAnalysisAI/InferenceX#2658, not chronological.
Grey curve is without spec dec. Red curve shows the performance with eagle.
