Linux kernel programming is a specialized field that involves writing code that interacts directly with the core of the operating system. While the official Linux Kernel Documentation
is the ultimate authority, several community-maintained GitHub repositories provide structured guides, full book source code, and PDF downloads to help developers master the subject. Essential GitHub Resources and PDF Guides
These repositories are highly recommended for their comprehensive coverage and updated material: The Linux Kernel Module Programming Guide (LKMPG) Description
: This is one of the most famous introductory guides for writing Loadable Kernel Modules (LKMs). Modern Support
: Unlike older versions on the web, this repository is actively maintained to support modern 5.x and 6.x kernels Availability : You can access it as a linux kernel programming pdf github full
or read it online. It covers basics like passing command-line arguments to modules, device drivers, and system calls. Linux Kernel Programming (Packt) Description
: This repository contains the code and resources for Kaiwan N. Billimoria’s book. Key Features : It focuses on the 5.4 LTS kernel
and covers kernel architecture, memory management, and CPU scheduling. : The repository often includes a companion volume specifically for character device drivers. Linux Kernel Development (3rd Edition) by Robert Love Description
: Widely considered the "definitive" work on kernel internals. Linux kernel programming is a specialized field that
: Detailed explanations of process management, scheduling, the virtual file system (VFS), and kernel synchronization. : While a classic, it is based on the 2.6 kernel
, so some specific APIs may be outdated compared to modern mainline kernels. Specialized Learning Repositories
For those looking for a "deep dive" or curated learning paths: Assembly language
For Linux Kernel Programming, several high-quality books and guides are available for free or as open-source projects on GitHub, ranging from introductory modules to deep-dive internals.
