    Use Cases & Benefits

    • Provides an in-depth, continuously updated book explaining Linux kernel internals and low-level system concepts.
    • Offers detailed, practical knowledge about Linux kernel internals that evolves with modern kernel versions for accurate learning.
    • Use for developers seeking to understand Linux kernel architecture and source code for system-level programming.
    • Use for students and engineers wanting to deepen their knowledge of assembly language and C in the context of Linux internals.
    • Use for contributors aiming to improve or extend Linux kernel features by gaining comprehensive insights into kernel mechanisms.

    About linux-insides

    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

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

    Translations

    Thanks to the volunteers, the posts about Linux are translated into different languages.

    [!NOTE] The translations may diverge from the original content.
