How does this skill help identify kernel hangs?

It provides techniques to extract the last successful checkpoint from logs, pinpointing which subsystem failed to initialize during the boot sequence.

Can I use this for boot time optimization?

Yes, the skill includes techniques for timing boot stages and strategies for deferring non-critical initialization to improve startup performance.

What phases of the boot process does it cover?

It covers seven distinct phases: Bootloader Handoff, Early Initialization, Memory Subsystem, Device Drivers, System Infrastructure, Testing, and Kernel Ready.

Does this skill support regression analysis?

Yes, it offers methods to compare boot logs from different versions to identify exactly when and where a regression was introduced.

Is it compatible with other Breenix tools?

It is designed to integrate seamlessly with kernel-debug-loop and log-analysis scripts for a comprehensive debugging workflow.

分析と監視

Analyzes and optimizes the Breenix kernel boot process from bootloader handoff to system ready state.

概要

This skill provides a specialized framework for diagnosing and refining the Breenix OS boot sequence. It helps developers track initialization phases—including memory allocation, GDT/IDT setup, and driver loading—to identify performance bottlenecks, resolve kernel hangs, and ensure correct subsystem ordering. By providing structured techniques for log analysis and checkpoint verification, it streamlines the kernel debugging process and facilitates boot time optimization through detailed timeline extraction and regression analysis.
