Key benefits

Discover how to write Linux kernel and module code for real-world products on the 6.1 LTS kernel

Implement industry-grade techniques in real-world scenarios for fast, efficient memory allocation and data synchronization

Understand and exploit kernel architecture, CPU scheduling, and kernel synchronization techniques

Description

The 2nd Edition of Linux Kernel Programming is an updated, comprehensive guide for those new to Linux kernel development. Built around the latest 6.1 Long-Term Support (LTS) Linux kernel, which is maintained until December 2026, this edition explores its key features and enhancements. Additionally, with the Civil Infrastructure Project extending support for the 6.1 Super LTS (SLTS) kernel until August 2033, this book will remain relevant for years to come. You'll begin this exciting journey by learning how to build the kernel from source. Step by step, you will then learn how to write your first kernel module by leveraging the kernel's powerful Loadable Kernel Module (LKM) framework. With this foundation, you will delve into key kernel internals topics including Linux kernel architecture, memory management, and CPU (task) scheduling. You'll finish with understanding the deep issues of concurrency, and gain insight into how they can be addressed with various synchronization/locking technologies (for example, mutexes, spinlocks, atomic/refcount operators, rw-spinlocks and even lock-free technologies such as per-CPU and RCU). By the end of this book, you'll build a strong understanding of the fundamentals to writing the Linux kernel and kernel module code that can straight away be used in real-world projects and products.

I have always been a fan of Linux kernels for the flexibility it offers and this book serves as a great guidance for me to understand the hows & whats of Linux kernels starting from setting the workspace to building the kernel from source. the book's content was a really value add as I could also get guidance to write my first kernel module along with important things to be taken care of like threads, memory allocation, synchronization etc.A must read book if you also want to deep dive into the world of Linux kernels. A great resource!

I found this book as impacting me as LDD (by Rubini etc) has been in its days, a de-facto standard established to the point that people keep searching for LDD4/LDD5 to these days, that much desirable.Since LDD3 the last update on 2.6, this book (as well as kernel debugging and hands-on systems programming) is a valuable source of information for modern kernels 5 and 6 for a few years to come.Knowledgeable and easy to follow, captivating attention to keep on reading it through, impressive for a technical book. LDD4+ has now found reincarnated, thank you very much for all the effort composing it!

I got on my desk a copy of "Linux Kernel Programmin (2E)" by Kaiwan N. Billimoriaand will shortly mention what this book is about.It is a book that you can read cover-to-cover to have a better understanding of kernel development,but I see also how it can be used as a reference when you are going to throw C code at your compilerand build a linux kernel.There is a number of scenario why you might want to do that:- You are recompiling the kernel for a new machine that needs better support- You are going to implement a kernel module and you need some context- You are going to work on the kernel yourselfWhile all of those use-cases for the book are technically a fit, apart from gaining somehigher understanding I see the most out of it if you are going to code on the kernel itself.There you have everything that is needed. You can go back and forth between your codeand the book, and still learn by doing.What mostly impressed me is the breath of the topics: the chapter about writinga config file for the kernel enlists a total of seven (7!) different strategiesto get started with a configuration file for your kernel.Also a lot of side tools are mentioned to help out with kernel development anddebugging.Quite some module development can be in theory done without fully understandingthe details of the kernel itself, but the deeper you reach, the more you willneed the details that are well discussed in the book.Memory allocation, CPU scheduling algorithms, the book does not try to savewords and describe in detail and plain language most things there is to know,not sparing plenty of references to other books and articles.Also, the material is up-to-date with the latest kernel.
