Does it support userspace binary testing?

Absolutely. It includes critical steps for building userspace test binaries before launching the kernel to ensure integration tests execute correctly.

Why is the Rust version pinned in these workflows?

Breenix kernel development relies on specific nightly features; pinning the version prevents unexpected breakage caused by changes in the Rust compiler.

How does this skill help with kernel testing?

It provides standardized patterns for running kernel tests within QEMU on GitHub Actions, including the necessary system dependencies and success signal monitoring.

Can this skill help reduce my CI build times?

Yes, it includes advanced caching configurations for Cargo registries and build targets that can reduce runtimes from ~10 minutes to ~2 minutes.

What happens if a kernel test hangs in CI?

The skill provides timeout strategies specifically tuned for CI environments, which are typically slower than local machines, to ensure jobs fail gracefully.

Deployment & DevOps

Streamlines the creation and optimization of GitHub Actions CI/CD pipelines specifically for Breenix OS kernel development.

About

This skill provides specialized guidance and templates for authoring robust GitHub Actions workflows tailored to the unique requirements of the Breenix kernel. It simplifies complex CI/CD tasks such as configuring QEMU virtualization, managing custom Rust targets (x86_64-unknown-none), and ensuring userspace binaries are correctly built before kernel testing. By implementing proven patterns for caching, timeout management, and automated artifact collection, this skill enables developers to maintain high-quality code and reliable feedback loops in a resource-intensive systems programming environment.

Key Features

Pre-configured templates for kernel smoke tests and full integration suites
Standardized system dependency management for QEMU and OVMF environments
Optimized Cargo caching strategies to significantly reduce CI build times
Automated artifact collection for kernel logs to simplify post-mortem debugging
4 GitHub stars
Automated Rust toolchain setup with pinned nightly versions and custom targets

Use Cases

Creating new CI pipelines for experimental kernel subsystems or features
Optimizing existing workflows to prevent timeouts and reduce CI costs
Debugging complex CI failures related to virtualization or cross-compilation
