Gain a firm practical understanding of the fundamentals of Linux kernel internals, learn to write high-quality kernel module code, and kernel synchronization

Key Features

Discover how to write Linux kernel and module code for real-world products
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

Book Description

The 2nd Edition of Linux Kernel Programming is an updated, comprehensive introduction for new programmers to the Linux kernel. This book uses the recent 5.10 Long-Term Support (LTS) Linux kernel series, which will be maintained until 2026, showing 5.X/6.X new features.

In this new edition, youll start the journey by learning how to build the kernel from source, including doing a kernel build for the popular Raspberry Pi. Youll then learn, step by step, how to write your first kernel module by leveraging the kernels powerful Loadable Kernel Module (LKM) framework. Youll then get to delve into key kernel internals topics including Linux kernel architecture, memory management, and CPU scheduling. Youll understand the deep issues of concurrency, and gain insight into how they can be addressed with various locking technologies (mutexes, spinlocks, atomic / refcount operators and even lock-free technologies).

By the end of this 2nd Edition book, youll have a better understanding of the fundamentals of writing Linux kernel and kernel module code that can be used in real-world projects and products.

Book 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. Youll 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 kernels 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. Youll 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, youll 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.

What you will learn

Configure and build the 6.1 LTS kernel from source
Write high-quality modular kernel code (LKM framework) for 6.x kernels
