Summary by CodeRabbit

  • Tests
    • Updated test configuration markers for hardware-specific test scenarios, adjusting skip conditions for post-Blackwell Ultra environments while refining coverage across different hardware configurations.

Review Change Stack

Description

The llm-models repo is out of sync on GB300 nodes.
Skip problematic test TestNanoV3Omni entirely on these
nodes since they do not meaningfully improve coverage
anyway.

📝 Walkthrough

Walkthrough

This PR adjusts pytest skip markers in the multimodal LLM API test file to control test execution across hardware generations. The TestNanoV3Omni class now has a class-level skip marker for post-Blackwell Ultra, while the nvfp4 case within test_auto_dtype carves out an exception by removing that marker.

Changes

Test Skip Marker Configuration

Layer / File(s) Summary
TestNanoV3Omni class-level and case-specific skip markers
tests/integration/defs/accuracy/test_llm_api_pytorch_multimodal.py
TestNanoV3Omni gains a @skip_post_blackwell_ultra class decorator (with B300/GB300 comments), while the nvfp4 parameter in test_auto_dtype updates its marks to only (skip_pre_blackwell,), removing skip_post_blackwell_ultra.

547-552: QA list updates are unnecessary for this marker-only gating change.

This keeps an already-listed test selected while enforcing hardware exclusions via pytest markers, which is the expected pattern for these integration QA lists.

As per coding guidelines: “hardware gating is expected to happen inside the test code/pytest markers,” and llm_function_core.txt already includes TestNanoV3Omni::test_auto_dtype parametrizations.
