Description

Guard CUDA graph defaults against the effective runtime capacity, preserve explicit graph settings and YAML/CLI precedence, and ensure repeated calls do not mutate reusable performance options.

Split the benchmark module coverage out of #21095 so it can be reviewed independently. This PR contains only its tests and any associated CI-list changes.

The production prerequisite #21095 merged into main as ff1aa0f7d35c on 2026-11-03. This test-only PR now includes that fix through a normal merge of main (b3634de3229a) and has passed current-head L0 CI; Code Owner review remains required.

Test Coverage

• The preserved module coverage passed in a fresh run of the original PR snapshot: 52 CPU, zero failures/errors/skips. The complete original snapshot passed 443 CPU + 9 GPU cases on RTX PRO 6000 Blackwell; this is not a runtime result for the rebased PR head.

• Current merged head 78216067e8e8: resolved the import conflict against main (b3634de3229a) by retaining both CudaGraphConfig and upstream QuantConfig. All applicable pre-commit hooks and whitespace checks passed. Independent AST review verified all 15 upstream definitions and the seven PR test functions (38 parametrized cases) remain intact; the effective PR diff is still 140 added test lines.

• Current-head remote validation (78216067e8e8): L0 #68221 completed SUCCESS, including the merge that preserved both CudaGraphConfig and QuantConfig. This supersedes the previous-head result and local environment limitation. Code Owner approval is still required.

• The seven split patches were checked for complete coverage of the original 22-file diff and exact recombination after the required upstream API compatibility changes.

• CI selection verified on main: The existing unittest/others directory entry in l0_cpu.yml selects test_bench.py, which is marked cpu_only; an individual test-file entry is not required. Directory selectors are expanded by tests/integration/defs/test_unittests.py, and Jenkins applies cpu_only / not cpu_only by stage.

PR Checklist

• Reviewed the applicable repository PR checklist items; the commit includes a DCO sign-off.

Merge readiness (2026-11-06)

Current head 78216067e8e8 has passing blossom-ci and DCO checks, no unresolved review threads, and no merge conflict with main in the GitHub mergeability check. GitHub still reports REVIEW_REQUIRED; the existing Code Owner review requests are the remaining merge gate. No source update or CI rerun is needed for the current passing head.

Walkthrough

The change adds unit tests for CUDA graph defaults and option precedence. The tests cover runtime capacities, explicit graph settings, disabled capture, repeated calls, and YAML versus CLI options.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 1 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Merge-readiness check (2026-11-06): current head 78216067e8e8 passed L0 #68221, blossom-ci and DCO are green, all review threads are resolved, and GitHub reports no merge conflict. The existing CPU unittest/others directory selector covers test_bench.py; no extra per-file CI-list entry is needed.

Updated the description to replace superseded local-environment/CI-list uncertainty with the verified current result. GitHub still reports REVIEW_REQUIRED; @QiJune @schetlur-nv, could you complete the pending Code Owner review? No source changes or additional CI rerun are needed for this head.

[github-actions]

Automatically added "ci: full pre-merge approved" because this PR has satisfied the required GitHub review approvals. Unresolved review conversations and other required checks remain independent merge requirements.
