Linux Kernel Programming

Gain a solid practical understanding and sufficient theoretical insight into Linux kernel internals while learning to write high-quality kernel module code and understanding the complexities of kernel synchronization Purchase of the print or Kindle book includes a free eBook in PDF format. Key Features 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 Book DescriptionThe 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…
