Description

Linux Kernel Programming is a comprehensive introduction for those new to Linux kernel and module development. This easy-to-follow guide will have you up and running with writing kernel code in next-to-no time. This book uses the latest 5.4 Long-Term Support (LTS) Linux kernel, which will be maintained from November 2019 through to December 2025. By working with the 5.4 LTS kernel throughout the book, you can be confident that your knowledge will continue to be valid for years to come. You’ll start the journey by learning how to build the kernel from the source. Next, you’ll write your first kernel module using the powerful Loadable Kernel Module (LKM) framework. The following chapters will cover key kernel internals topics including Linux kernel architecture, memory management, and CPU scheduling. During the course of this book, you’ll delve into the fairly complex topic of concurrency within the kernel, understand the issues it can cause, and learn how they can be addressed with various locking technologies (mutexes, spinlocks, atomic, and refcount operators). You’ll also benefit from more advanced material on cache effects, a primer on lock-free techniques within the kernel, deadlock avoidance (with lockdep), and kernel lock debugging techniques. By the end of this kernel book, you’ll have a detailed understanding of the fundamentals of writing Linux kernel module code for real-world projects and products.

Who is this book for?

This book is for Linux programmers beginning to find their way with Linux kernel development. If you’re a Linux kernel and driver developer looking to overcome frequent and common kernel development issues, or understand kernel intervals, you’ll find plenty of useful information. You’ll need a solid foundation of Linux CLI and C programming before you can jump in.

This book covers the vast field that is Linux Kernel Programming with sufficient amount of detail needed for module/driver development. The book is a hands-on guide as each chapter features example code, designed to illustrate the presented topics, which you can try out for yourself. Along with the code come questions (with solutions), exercises and a very well composed 'Further Reading' list, all of which you can download from the books GitHub repository. The book starts with fundamentals such as 'Building the Linux Kernel from Source' and 'Writing Your First Kernel Module' and leads to advanced topics such as memory management, scheduling and synchronization/concurrency. Thanks to the easy to follow instructions, this book is for anyone with a minimal amount of experience with Linux, C and embedded-/low-level-programming. Aside from the sound technical expertise this book brings to the table, it is written in a style that is inspiring and motivational. This book is actually fun to read and I would recommend it to anyone who would like to learn the skills and knowledge needed to become a Linux Kernel developer.

Great book. Well written and easy to follow.

Swaran May 30, 2021

I was trying to find out a book with latest linux kernel development. Most of the available books are outdated. Finally found this book. This book provide the study material for which I was waiting since long. Book is written in clear and precise manner and guide the reader for "learning by doing" methodology.Complete book is divide into three sections1. First section explains about setting up the development environment, how to build linux kernel(of-course kernel 5.x) from source, how to write the kernel module2. Second section give in-depth understanding about kernel internals, processes, threads, memory management internals, kernel memory allocation, and deep understanding of CPU Schedulers.3. Third section goes even more deeper and explain about kernel synchronisation- critical sections, mutex and spinlock, debugging of locks in kernel.

I met this guy and he is the most genuine person who has knowledge on kernel in depth. Read his book and helps me to brush the concepts and gives more charity on various topics such as memory management, cpu scheduling, interrupts, task structure, driver related concepts and many things. you will find the latest information as compare to other LDD books.definetly recommend this book to all who wants to deep dive into coding level, kernel concepts.

Nayana Rao Mar 23, 2021

If you are looking for a comprehensive guide to Linux kernel and it’s configuration for a custom platform, I highly recommend this book. The book is very detailed and comes with the Github source base with a lot of sample codes to assist you.Disclaimer: I have helped with the technical review of this book.
