How does it help with kernel panics?

The skill provides automated log parsing to identify faulting addresses and error codes, offering specific fixes for common causes like unmapped stacks.

Can it differentiate between a hang and a slow test?

Yes, it analyzes output frequency and log checkpoints to determine if the kernel is in an infinite loop or simply running slowly in the CI environment.

Does this work with any kernel project?

While optimized for the Breenix project, its patterns and workflows are applicable to general OS development using QEMU and GitHub Actions.

What types of failures can this skill detect?

It detects double faults, page faults, test timeouts, missing dependencies, compilation errors, and missing userspace binaries.

배포 및 DevOps

Diagnoses and resolves failed GitHub Actions CI/CD runs for Breenix kernel development by analyzing QEMU logs, kernel panics, and system timeouts.

소개

Breenix CI Failure Analysis is a specialized skill designed to streamline the debugging process for kernel-level CI/CD workflows. It provides a systematic approach to identifying the root causes of GitHub Actions failures, including complex issues like double faults, page faults, and QEMU environment discrepancies. By parsing log artifacts and detecting known failure patterns, it helps developers quickly distinguish between legitimate kernel bugs, environment misconfigurations, and test timeouts, offering actionable remediation steps for each scenario to accelerate kernel development cycles.
