Linux insides

This repository contains a book-in-progress about the Linux kernel and its insides.

The goal of this project is simple – to share knowledge about the Linux kernel internals and related low-level topics. If you’re curious about what’s under the hood, see the Table of Contents.

[!IMPORTANT] I started writing this series when the latest version of the kernel was 3.18. A lot has changed since then, and I am in progress of updating the content to reflect modern kernels (v6.16+). I’ll continue revising the posts as the kernel evolves.

Requirements

• Prior knowledge about the Assembly language
• Proficiency with the C programming language
• Additionally, you can find lots of useful information about x86_64 processors in Intel Software Developer Manuals

[!TIP] You can get started with Assembler with my other series of posts about the Assembly programming.
