## What it is
An open-source, in-progress book about the Linux kernel internals, covering booting, initialization, interrupts, system calls, memory management, and other low-level topics. It is written for developers with C and x86_64 assembly knowledge who want to understand how the kernel works under the hood.

## Use cases
- learn how the Linux kernel boots from the bootloader
- understand Linux kernel memory management internals
- study how system calls are implemented in the kernel
- learn about interrupts and interrupt handlers in Linux
- understand kernel synchronization primitives like spinlocks and mutexes
- prepare for contributing to the Linux kernel
- learn x86_64 fundamentals like paging and the IDT

## When to choose
- you want a free, in-depth, source-code-driven explanation of Linux kernel internals
- you already know C and some x86_64 assembly and want to go deeper into the kernel
- you are preparing to read or contribute to kernel source code

## When to avoid
- you need a beginner-friendly introduction to Linux without assembly or C background
- you need complete, up-to-date coverage of the latest kernel - many chapters are still pending review for modern kernels
- you need a hands-on kernel development tutorial rather than conceptual internals explanations

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation
- domain: operating-systems, tutorials, developer-tools
- platform: cpp, c
- tags: linux-kernel, kernel-internals, book, open-source-book, x86-64, assembly, booting, memory-management, system-calls, interrupts, linux
