Ever wondered what really happens under the hood when you run Linux? This book pulls back the curtain on one of the most sophisticated operating systems ever created, giving you the knowledge to not just use Linux, but to understand and improve it from the inside out.
Unlike dry technical manuals that leave you more confused than when you started, Linux Kernel Development presents complex concepts in a way that actually makes sense. Written by someone who's been there—developing kernel code daily—this third edition combines practical experience with clear explanations. You'll get both the theoretical framework and hands-on knowledge you need to navigate the kernel's intricate architecture.
The book takes you on a comprehensive tour through Linux's core subsystems. You'll explore process management and scheduling with the innovative CFS scheduler, dive deep into memory management and the page cache, understand the virtual file system (VFS), and learn the ins and outs of kernel synchronization. New to this edition is an all-new chapter on kernel data structures, extended coverage of virtual memory, and practical debugging techniques that actually work in real-world scenarios.
This isn't just academic knowledge—it's practical, battle-tested information you can apply immediately. Learn how to interrupt handlers work, understand portability concerns across different architectures, discover efficient memory allocation strategies, and get insider tips on submitting patches that actually get accepted by the kernel community. The author's experience comes through in every chapter, sharing not just what works, but why it works and when to apply different approaches.
Whether you're just starting to explore kernel development or you're an experienced programmer looking to deepen your understanding, this book meets you where you are. The clear explanations, concrete examples, and practical focus make complex topics accessible without dumbing them down. By the time you finish, you'll have the confidence and knowledge to tackle kernel development projects effectively and contribute meaningfully to the Linux ecosystem.
