Inline comments:
In `@docker/Dockerfile.multi`:
- Line 80: Align the quack-kernels dependency with the CUTLASS DSL 4.8.0.dev0
installation by replacing the stale 0.6.4 constraint in constraints.txt with the
compatible Git revision already specified in requirements.txt. Update setup.py
so constraints.txt does not reintroduce quack-kernels 0.6.4 during wheel
installation.
In `@requirements.txt`:
- Line 84: Regenerate security_scanning/pyproject.toml and
security_scanning/poetry.lock using scripts/generate_lock_file.py so they
reflect the current requirements.txt versions, including nvidia-cutlass-dsl
4.8.0.dev0 and quack-kernels 0.6.4.
In `@tensorrt_llm/_torch/attention_backend/sparse/minimax_m3/msa_utils.py`:
- Around line 46-47: Update _install_msa_cutlass_compatibility() to ignore
ImportError only when quack or quack.activation itself is missing, and re-raise
import failures caused by dependencies or code executed within the module.
Ensure msa_package_available() cannot report success when compatibility alias
installation failed.

CUTLASS DSL 4.8 removed the `context` parameter from Task's run methods. ResourceContext now reaches a task through `self._resource_context`, which `init_variables()` stores; the resource-side context API is unchanged. The vendored prims_ts Task subclasses still declared and forwarded `context`, so tracing the FMHA decode and 2CTA MLA decode kernels failed: Task._run_task_body_impl() got an unexpected keyword argument 'context' Task._run_pre_work_loop_entries() takes 2 positional arguments but 3 were given The fix belongs upstream rather than in the downstream compatibility patch, so it was exported to the prims_ts source tree and pinned here. The vendor now tracks trtllm-prims-ts-dev, which carries the migration; the persistent compatibility patch is unchanged and still holds only the TensorRT-LLM environment adaptations. Verified on B200 (SM100): FMHA decode, 2CTA MLA decode, block-sparse and context prefill all produce bit-identical output to the 4.7.0 baseline. Signed-off-by: rosong11 <rosong@nvidia.com>
… 4.8 API CUTLASS DSL 4.8 drops two APIs the Blackwell NVFP4 MoE kernels still use. `CooperativeGroup` no longer accepts `alignment`. It had been deprecated since 4.7, where the constructor only warned and never stored or used the value, so removing the argument is a no-op. The MoE-as-dense-GEMM FC2 kernel was the only caller in the tree still passing it. The NVVM dialect no longer exports `Tcgen05MMAScaleVecSize`; the 1X/2X/4X selector and the block-scale selector are now separate enums, and `tcgen05.mma.block_scale` renamed its operands (`mma_kind` -> `kind`, `d`/`a`/`b` -> `matrix_d`/`matrix_a`/`matrix_b`, `scale_vec_size` -> `block_scale`). Update the MegaMoE mainloop to the new spelling. The neighbouring `compatible_to_old_nvvm` branch is left alone: it is guarded on `Tcgen05GroupKind`, which exists in neither 4.7 nor 4.8. Verified on SM100 by compiling both kernels at the geometries their CI cases use: FC2 dense GEMM at [256-1-256-1] and MegaMoE at e60_k4_h2048_i1408. Both fail with the reported errors before this change and compile after it. Signed-off-by: rosong11 <rosong@nvidia.com>
