Purchase of the print or Kindle book includes a free eBook in PDF format.Key FeaturesDiscover how to write Linux kernel and module code for real-world productsImplement industry-grade techniques in real-world scenarios for fast, efficient memory allocation and data synchronizationUnderstand and exploit kernel architecture, CPU scheduling, and kernel synchronization techniquesBook Description
The 2nd Edition of Linux Kernel Programming is an updated, comprehensive guide for new programmers to the Linux kernel. This book uses the recent 6.1 Long-Term Support (LTS) Linux kernel series, which will be maintained until Dec 2026, and also delves into its many new features. Further, the Civil Infrastructure Project has pledged to maintain and support this 6.1 Super LTS (SLTS) kernel right until August 2033, keeping this book valid for years to come!
You'll begin this exciting journey by learning how to build the kernel from source. In a step by step manner, 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 (e.g., 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 have a much better understanding of the fundamentals of writing the Linux kernel and kernel module code that can straight away be used in real-world projects and products.What you will learnConfigure and build the 6.1 LTS kernel from sourceWrite high-quality modular kernel code (LKM framework) for 6.x kernelsExplore modern Linux kernel architectureGet to grips with key internals details regarding memory management within the kernelUnderstand and work with various dynamic kernel memory alloc/dealloc APIsDiscover key internals aspects regarding CPU scheduling within the kernel, including cgroups v2Gain a deeper understanding of kernel concurrency issuesLearn how to work with key kernel synchronization primitivesWho this book is for
