Essential Linux Device Drivers by Sreekrishnan Venkateswaran Publisher: Prentice Hall Pub Date: March 27, 2008 Print ISBN-10: 0-13-239655-6 Print ISBN-13: 978-0-13-239655-4 Pages: 744 Table of Contents | Index Overview "Probably the most wide ranging and complete Linux device driver book I've read." -Alan Cox, Linux Guru and Key Kernel Developer "Very comprehensive and detailed, covering almost every single Linux device driver type." -Theodore Ts'o, First Linux Kernel Developer in North America and Chief Platform Strategist of the Linux Foundation The Most Practical Guide to Writing Linux Device Drivers Linux now offers an exceptionally robust environment for driver development: with today's kernels, what once required years of development time can be accomplished in days. In this practical, example-driven book, one of the world's most experienced Linux driver developers systematically demonstrates how to develop reliable Linux drivers for virtually any device. Essential Linux Device Drivers is for any programmer with a working knowledge of operating systems and C, including programmers who have never written drivers before. Sreekrishnan Venkateswaran focuses on the essentials, bringing together all the concepts and techniques you need, while avoiding topics that only matter in highly specialized situations. Venkateswaran begins by reviewing the Linux 2.6 kernel capabilities that are most relevant to driver developers. He introduces simple device classes; then turns to serial buses such as I2C and SPI; external buses such as PCMCIA, PCI, and USB; video, audio, block, network, and wireless device drivers; user-space drivers; and drivers for embedded Linux–one of today's fastest growing areas of Linux development. For each, Venkateswaran explains the technology, inspects relevant kernel source files, and walks through developing a complete example. • Addresses drivers discussed in no other book, including drivers for I2C, video, sound, PCMCIA, and different types of flash memory • Demystifies essential kernel services and facilities, including kernel threads and helper interfaces • Teaches polling, asynchronous notification, and I/O control • Introduces the Inter-Integrated Circuit Protocol for embedded Linux drivers • Covers multimedia device drivers using the Linux-Video subsystem and Linux-Audio framework • Shows how Linux implements support for wireless technologies such as Bluetooth, Infrared, WiFi, and cellular networking • Describes the entire driver development lifecycle, through debugging and maintenance • Includes reference appendixes covering Linux assembly, BIOS calls, and Seq files Essential Linux Device Drivers by Sreekrishnan Venkateswaran Publisher: Prentice Hall Pub Date: March 27, 2008 Print ISBN-10: 0-13-239655-6 Print ISBN-13: 978-0-13-239655-4 Pages: 744 Table of Contents | Index Overview "Probably the most wide ranging and complete Linux device driver book I've read." -Alan Cox, Linux Guru and Key Kernel Developer "Very comprehensive and detailed, covering almost every single Linux device driver type." -Theodore Ts'o, First Linux Kernel Developer in North America and Chief Platform Strategist of the Linux Foundation The Most Practical Guide to Writing Linux Device Drivers Linux now offers an exceptionally robust environment for driver development: with today's kernels, what once required years of development time can be accomplished in days.

Foreword If you're holding this book, you may be asking yourself: Why "yet another" Linux device driver book? Aren't there already a bunch of them? The answer is: This book is a quantum leap ahead of the others. First, it is up-to-date, covering recent 2.6 kernels. Second, and more important, this book is thorough. Most device driver books just cover the topics described in standard Unix internals books or operating system books, such as serial lines, disk drives, and filesystems, and, if you're lucky, the networking stack. This book goes much further; it doesn't shy away from the hard stuff that you have to deal with on modern PC and embedded hardware, such as PCMCIA, USB, I2C, video, audio, flash memory, wireless communications, and so on. You name it, if the Linux kernel talks to it, then this book tells you about it. No stone is left unturned; no dark corner is left unilluminated. Furthermore, the author has earned his stripes: It's a thrill ride just to read his description of putting Linux on a wristwatch in the late 1990s! I'm pleased and excited to have this book as part of the Prentice Hall Open Source Software Development Series. It is a shining example of the exciting things happening in the Open Source world. I hope that you will find here what you need for your work on the kernel, and that you will enjoy the process, too! Arnold Robbins Series Editor
