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.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

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 Most of the available books are outdated.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.

Have you been wanting to figure out the innards of the Linux kernel without getting overwhelmed or have been working without enough context to actually understanding it, here is a fantastic book.If you are fascinated with operating systems and new to it, if you have wondered what terms like system calls, timers, threads mean and how they are developed? This book is for you.Major subsystems and features of the Linux kernel like System calls, Memory Management, Loadable Kernel Module framework, Kernel config, Virtual Address Space, Page Cache and Kernel build(for x86 and ARM) are detailed very well in the book. The delivery through both practical and theoretical focus, can meet the expectations of both professional and academic needs.When used along with Linux kernel documentation, this book is bound to provide a deeper, well structured understanding of Linux kernel architecture.Yet to complete reading the entire book and I'm sure that it will keep me interested.

This is a great book for those wanting to get into Linux kernel development. It has a good flow to the writing and doesn't try and bury you with too much deep knowledge as a beginner (just enough to give you the basics of the concepts being discussed). if you purchase this book there is a second book with more depth on programming provided free (on the books website github). I enjoyed this book so much I've purchased the second book for my kindle reader to support the author.I've also purchased Kaiwan's book on Linux kernel debugging which is also an excellent read; giving you a good introduction to all the different methods/tools that can be used to help you debug those stubborn issues you'll inevitably encounter working as a kernel developer.I can't wait to read the next edition of this book coming out in January; revised for the 6.x kernel. FYI, I've read this book and worked through all the examples on the latest Linux stable kernel (as of this review 6.4.x/6.5.x-rcX).You won't regret getting this book if you want to start down the path of being a Linux kernel developer! I'd love to see a book from Kaiwan on developing module/drivers using Rust (with it's support now included in Linux kernel since 6.2). :-)

Informative lot of information ,great for coding. I Suggest To buy this book you can buy, no regret plse buy.
