This backports #5544 to v2.1. GB200 B3240 DPUs can report 900-9D3B6-00CN-PN0 in bootstrap Redfish data and 900-9D3B6-00CN-P_Ax after Scout records the device identity. The v2.1 selector does not accept either value, so DPF and Non-DPF provisioning can select the generic BF3 profile for those devices even when the rack is identified as GB200.

This adds both exact identities to the shared GB200 B3240 selector. The separate GB200 rack check remains required, and other B3240 prefixes remain rejected.

The v2.1 integration tests still invoke grpcurl. #5386 removed it from main's build containers, so release checks that do not rebuild a base container pull latest and fail before the integration tests start. This also makes the v2.1 workflow use its existing v2.1-latest x86_64 and aarch64 build container tags when those containers are not rebuilt.

Additional Notes

The existing v2.1 DPF and Non-DPF integrations already consume this shared selector, so this PR does not change their NVConfig assignments.

The v2.1-latest build container tags were published from the v2.1 Dockerfiles, which still install grpcurl. A Dockerfile change still selects the versioned container produced by that CI run. Mirrors continue using the latest tag from their configured source registry.

GB200 B3240 devices can report `PN0` in bootstrap Redfish data and `P_Ax` after Scout records the device identity. Neither value is in the v2.1 selector, so both provisioning paths can retain the generic BF3 profile on matching GB200 racks.

Accept both values through the shared selector while preserving the separate GB200 rack check and rejecting other B3240 prefixes.

This supports NVIDIA#5545

Summary by CodeRabbit

  • New Features

    • Added support for two additional GB200/B3240 hardware part numbers.
  • Bug Fixes

    • Improved hardware identifier recognition with case-insensitive and whitespace-trimmed matching.
  • Tests

    • Expanded coverage to verify recognition of the newly supported hardware identifiers and identities.
    • Added validation for consistent hardware identity resolution.

Walkthrough

The GB200/B3240 trusted identity list accepts two additional part numbers. CI fallback image selection now varies by repository for x86_64 and aarch64 containers.

Changes

GB200/B3240 identity support

Layer / File(s) Summary
Identity selector and validation
crates/libmlx-model/src/nvconfig.rs
The selector accepts 900-9D3B6-00CN-PN0 and 900-9D3B6-00CN-P_Ax. Documentation and tests cover the expanded identity list and resolve both identities to Gb200B3240V1.

CI fallback images

Layer / File(s) Summary
Fallback image selection
.github/workflows/ci.yaml
The canonical NVIDIA/infra-controller repository uses v2.1-latest fallback images. Other repositories retain the latest source-registry tag for x86_64 and aarch64.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to e5370

The PR adds the required GB200 device identities and updates the v2.1 build-container selection without any actionable merge-blocking risk remaining; it is merge-ready after normal checks and review.

The v2.1 integration tests still invoke `grpcurl`. NVIDIA#5386 removed it from `main`'s build containers, so release checks that do not rebuild a base container pull `latest` and fail before the integration tests start.

Use the existing `v2.1-latest` x86_64 and aarch64 tags for canonical v2.1 checks. Those tags were built from the v2.1 Dockerfiles that still install `grpcurl`, while a Dockerfile change continues to select the versioned image produced by that run. Mirrors continue using the `latest` tag from their configured source registry.

This supports NVIDIA#5545
