Description

Linux Kernel Programming Part 2 - Char Device Drivers and Kernel Synchronization is an ideal companion guide to the Linux Kernel Programming book. This book provides a comprehensive introduction for those new to Linux device driver development and will have you up and running with writing misc class character device driver code (on the 5.4 LTS Linux kernel) in next to no time. You'll begin by learning how to write a simple and complete misc class character driver before interfacing your driver with user-mode processes via procfs, sysfs, debugfs, netlink sockets, and ioctl. You'll then find out how to work with hardware I/O memory. The book covers working with hardware interrupts in depth and helps you understand interrupt request (IRQ) allocation, threaded IRQ handlers, tasklets, and softirqs. You'll also explore the practical usage of useful kernel mechanisms, setting up delays, timers, kernel threads, and workqueues. Finally, you'll discover how to deal with the complexity of kernel synchronization with locking technologies (mutexes, spinlocks, and atomic/refcount operators), including more advanced topics such as cache effects, a primer on lock-free techniques, deadlock avoidance (with lockdep), and kernel lock debugging techniques. By the end of this Linux kernel book, you'll have learned the fundamentals of writing Linux character device driver code for real-world projects and products.

Who is this book for?

An understanding of the topics covered in the Linux Kernel Programming book is highly recommended to make the most of this book. This book is for Linux programmers beginning to find their way with device driver development. Linux device driver developers looking to overcome frequent and common kernel/driver development issues, as well as perform common driver tasks such as user-kernel interfaces, performing peripheral I/O, handling hardware interrupts, and dealing with concurrency will benefit from this book. A basic understanding of Linux kernel internals (and common APIs), kernel module development, and C programming is required.

What you will learn

Write a simple yet complete misc class character device driver

Perform user-kernel interfacing using popular methods

Understand and handle hardware interrupts confidently

Perform I/O on peripheral hardware chip memory

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

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.

For example:

Book is very well structured and lots of information with examples. Foundation is laid out in the "Linux Kernel Programming" Part-1 book and is must to read the first book in order to understand the concepts explained in this (Part-2) book. Off topics information/link are provided which is great. Book is good for both freshers and experienced. I would really recommend this book!!

Glad to read this book. I recommand this book. I continue to read it to learn more things. He is great trainer and author too. I always recommend to read his books and blogs.

I recommend reading part 1 of Linux Kernel Programming before starting this book. Even if you start off with this book directly, there is a lot to be gained.

Amazon Customer Aug 20, 2021

the interesting part I like in this book is that the author has made it self-contained and the words used are easy to understand. this book has used the latest kernel release which gave a good understanding of both the concepts and source code, the author also pointed some good websites where you can start your contribution and the challenges conducted by the Linux Foundation. Some other book is also available which gives a good understanding of the concepts about Linux kernel but those books are written during kernel 2.6 release and the source code are outdated which is really a headache when you want to understand both the high-level concepts and the source code written

Reader Jul 02, 2022

Books aren't bad, regarding the content itself. Fairly poorly typeset but whatever. But read this!!! Dozens of pages of the Part 2 are literally the same, e.g. page 309 Part 2 is identical to page 597 of Part 1 and so on. This is something I haven't ever seen. They have just copied pages to make the Part 2 thicker. Insane.
