Several notable open-source projects and repositories on GitHub host the "story" of Linux kernel programming, ranging from legendary guides to modern textbooks. While the official kernel development happens via mailing lists, GitHub serves as the primary mirror for source code and a hub for educational PDFs and documentation. 📘 Essential Programming Guides

The Linux Kernel Module Programming Guide (LKMPG): A cornerstone text originally by Ori Pomerantz, now maintained by Jim Huang and others. It provides hands-on examples for modern 5.x and 6.x kernels.

PDF Access: Latest versions are often available at sysprog21/lkmpg.

Linux Kernel Programming (Packt): Written by Kaiwan N Billimoria, this is a modern, comprehensive guide focusing on the 5.4 LTS kernel.

Repository: PacktPublishing/Linux-Kernel-Programming includes code examples and a link to a free DRM-free PDF for print/Kindle owners.

Part 2: Focuses on character device drivers and synchronization. 📚 Classic Textbooks on GitHub

Many users maintain personal "ebook" repositories containing classic PDFs for educational purposes: The Linux Kernel Module Programming Guide - GitHub Pages

Note: Direct PDFs are rarely stored on GitHub due to file size limits, but official documentation and books are often linked from repositories.

How to Build a Self-Study Curriculum Using These Resources

Simply downloading PDFs and starring GitHub repos does nothing. Here is a 6-week roadmap.

Configure kernel (use current config as base)

cp /boot/config-$(uname -r) .config make olddefconfig

Pitfall 3: Ignoring Kernel Coding Style

• Problem: Your patch gets rejected because of indentation or brace placement.
• Solution: Read the coding-style.rst PDF (in kernel docs). Use scripts/checkpatch.pl from the kernel source.

4. packtublishing/Linux-Kernel-Programming

Stars: 350+
This is the official companion repository for the Packt book Linux Kernel Programming (by Kaiwan Billimoria).

• What you get: Chapter-wise source code, lab solutions, and a detailed PDF guide for setting up QEMU + GDB kernel debugging.
• Why it's special: Unlike academic PDFs, this repo is maintained for recent kernels (5.10+).
