Device drivers make it possible for your software to communicate with your hardware, and because every operating system has specific requirements, driver writing is nontrivial. When developing for FreeBSD, you've probably had to scour the Internet and dig through the kernel sources to figure out how to write the drivers you need. Thankfully, that stops now. In FreeBSD Device Drivers, Joseph Kong will teach you how to master everything from the basics of building and running loadable kernel modules to more complicated topics like thread synchronization. After a crash course in the different FreeBSD driver frameworks, extensive tutorial sections dissect real-world drivers like the parallel port printer driver.
Concise descriptions and extensive annotations walk you through the many code examples. Don't waste time searching man pages or digging through the kernel sources to figure out how to make that arcane bit of hardware work with your system. FreeBSD Device Drivers gives you the framework that you need to write any driver you want, now.

Table of Contents
Chapter 1: Building and Running Modules
"At last, a definitive and authoritative book on FreeBSD device drivers! Kong's clear mastery of his subject shines through every page."
"FreeBSD Device Drivers is an excellent guide to the APIs used to write a device driver for FreeBSD."
"I'd recommend the book for anybody that needs an introduction to drivers. The walk throughs will get people up to speed, as well as introduce many of the uniquely FreeBSD quirks one needs to know to integrate with FreeBSD."
"I am pleased to see No Starch provide a forum for books like this. They continue to produce high-quality works that read well and address subjects seldom found elsewhere."
"I like this book. It fills a definite need, and does it well."
"This book is definitely a must have for anybody interested in how FreeBSD device drivers are designed, not to mention those who are interested in writing their very own ones for the FreeBSD operating system!"
"This book is a no nonsense, straight to the point document that helps you get to the content quickly."
"Definitely an excellent book with all the information you’ll need to start developing your own FreeBSD device drivers."
"Strikes a pretty good balance for its stated purpose. Its mostly 'just the facts ma’am' style works well, but it provides plenty of references for those wanting more detail or background. This is definitely worth a read if device drivers in FreeBSD are something you need or want to know about."
