This repository is a comprehensive, in-progress book titled 'Linux insides' that explains Linux kernel internals through detailed, code-driven tutorials. It is not a traditional software application but a documentation project with supporting scripts for building, validating, and exporting the book. The content covers boot process, initialization, interrupts, system calls, memory management, synchronization, timers, cgroups, and more, with extensive references to actual kernel source code. The project includes a Makefile, Dockerfile, and CI/CD workflows for automated checks and ebook generation. While the primary deliverable is educational material, the repository contains reusable scripts for code snippet validation and LaTeX PDF generation that can be extracted for other documentation projects.
