For decades, the Linux kernel has stood as a titan of open-source engineering—powering everything from supercomputers to smartphones. For developers, diving into kernel programming is a rite of passage. It demands precision, a deep understanding of C and assembly, and an intimate knowledge of operating system concepts.
However, finding high-quality learning resources is notoriously difficult. Many textbooks are outdated (referencing Linux 2.6), while official documentation is dense and fragmented. This is where the GitHub ecosystem shines.
In this guide, we will explore the holy grail of self-directed learning: high-quality Linux kernel programming PDFs available on GitHub. We will cover where to find them, how to verify their quality, and which repositories stand above the rest. linux kernel programming pdf github high quality

Quality Score: ⭐⭐⭐⭐½ Unlocking the Core: The Ultimate Guide to High-Quality
The canonical Linux Device Drivers (LDD) stopped at version 3. However, the community has been backporting the examples. This repository uses a Sphinx build system to generate a pristine PDF that compiles against kernel 5.15 LTS and 6.1 LTS.
What you get: A 450+ page PDF covering char drivers, concurrency (mutexes, spinlocks), advanced memory allocation, and PCIe/USB subsystems. The code examples are pullable as a separate tarball. Use QEMU + GDB (debugging across VM boundaries)
Now, let’s align those PDFs with live, high-quality GitHub repositories that actually compile and run on recent kernels (5.10+).
| Repository | Stars (approx) | Kernel Version | Quality Signal |
|------------|----------------|----------------|----------------|
| torvalds/linux | 170k+ | Latest -rc | Ultimate source but not for beginners |
| sysprog21/lkmpg | 2k+ | 5.x – 6.x | Actively maintained; CI builds examples |
| jserv/linux-device-drivers | 1.5k+ | 6.x | Code from LDD3 updated for modern ARM/x86 |
| d0u9/linux-kernel-module | 800+ | 5.4 – 6.1 | Minimal examples: timers, workqueues, kthreads |
| linux-kernel-labs/linux-kernel-labs | 700+ | 5.15 LTS | Used in university OS courses (UCSC, etc.) |
| packtpublishing/Linux-Kernel-Programming | 400+ | 5.10 | Companion code for Packt book, well-structured |
