From 1f8a63442a12ccd4bd0346c3cf487fd8c2967bae Mon Sep 17 00:00:00 2001 From: Jason Ma Date: Tue, 16 Jun 2026 12:59:41 +0800 Subject: [PATCH 1/7] fix(onboard): detect NVIDIA GPU via lspci when nvidia-smi unavailable Preflight [1/8] skipped the install_nvidia_container_toolkit / CDI remediation when NVIDIA GPU hardware was present but the driver was not loaded. The CDI assessment gate requires assessment.hasNvidiaGpu, yet detectNvidiaGpu() derived that flag solely from nvidia-smi. With the driver unloaded nvidia-smi is unavailable, so hasNvidiaGpu was false, cdiNvidiaGpuSpecMissing stayed false, and onboard advanced past [1/8] without emitting the blocking toolkit/CDI remediation block. Fall back to an lspci PCI-bus hardware probe when nvidia-smi is absent/empty so a physically present NVIDIA GPU is still detected and the missing-spec + install_nvidia_container_toolkit remediation fires and blocks onboarding.

So the remediation was computed but never enforced and onboard advanced past [1/8]. Pass only the EXPLICIT GPU opt-out (--no-gpu) to the gate, not the auto-disable, via a new pure shouldEnforceCdiNvidiaGpuSpec() helper (unit-tested). An explicit --no-gpu still skips enforcement so a host with an unusable GPU can onboard CPU-only. Verified on a real NVIDIA H100 host (nvidia-smi hidden, toolkit removed, Docker CDI configured, spec wiped): onboard now blocks at [1/8] with the install_nvidia_container_toolkit remediation and exits non-zero, instead of continuing to [2/8].

This brings onboard.ts back to net-neutral per the codebase-growth-guardrails check (-26/+15 vs main). Also removes the !sandboxGpuConfig.sandboxGpuEnabled term from the opted-out check (the #5489 bypass) and drops verbose comment blocks — the parameter name explicitlyOptedOutGpuPassthrough makes the intent self-documenting.

The two new lspci fallback tests each used a 3-branch if chain inside their runCaptureImpl inline. Extract those to runCaptureWithLspci() which encodes command dispatch as a Map lookup and uses ternaries, keeping the test bodies linear and the total if-statement count at 12 (unchanged from base).
