Linux Device Drivers is already a classic. This third edition covers the significant changes to Version 2.6 of the Linux kernel, which simplifies many activities, and has subtle new features that can make a driver both more efficient and more flexible. Readers don't have to be kernel hackers to understand and enjoy this book. All they need is an understanding of the C programming language and some background in Unix system calls. Guided by full-featured examples that they can compile and run without special hardware, they'll learn how to write drivers for character devices, block devices, and network interfaces. This edition gives them new chapters on important types of drivers not covered previously, such as consoles, USB drivers, sound, video, and more. For those curious about how an operating system does its job, Linux Device Drivers offers insights into address spaces, asynchronous events, and I/O.
