vbios_mismatch

Overview

Verifies consistent VBIOS versions across all GPUs using nvmlDeviceGetVbiosVersion(). If --gpu_vbios is not specified, auto-detects the expected version from the first GPU and validates all other GPUs match.

Command-Line Options

Option	Type	Default	Description
--gpu_vbios	String	""	Expected VBIOS version (auto-detect from first GPU if empty)
--timeout	Integer	300	Command execution timeout in seconds
--sink	String	do_nothing	Telemetry sink destination
--sink-opts	Multiple	-	Sink-specific configuration
--verbose-out	Flag	False	Display detailed output
--log-level	Choice	INFO	DEBUG, INFO, WARNING, ERROR, CRITICAL
--log-folder	String	/var/log/fb-monitoring	Log directory
--heterogeneous-cluster-v1	Flag	False	Enable heterogeneous cluster support

Exit Conditions

Exit Code	Condition
OK (0)	Feature flag disabled (killswitch active)
OK (0)	All GPUs have consistent VBIOS versions
CRITICAL (2)	VBIOS version mismatch detected
UNKNOWN (3)	Unable to retrieve VBIOS information
