Device drivers literally drive everything you're interested in--disks, monitors,
keyboards, modems--everything outside the computer chip and memory. And writing
device drivers is one of the few areas of programming for the Linux operating
system that calls for unique, Linux-specific knowledge. For years now, programmers
have relied on the classic Linux Device Drivers from O'Reilly to master this critical
subject. Now in its third edition, this bestselling guide provides all the information
you'll need to write drivers for a wide range of devices.
- Over the years the book has helped countless programmers learn:
- how to support computer peripherals under the Linux operating system
- how to develop and write software for new hardware under Linux
- the basics of Linux operation even if they are not expecting to write a
driver
The new edition of Linux Device Drivers is better than ever. The book covers
all the significant changes to Version 2.6 of the Linux kernel, which simplifies
many activities, and contains subtle new features that can make a driver both
more efficient and more flexible. Readers will find new chapters on important
types of drivers not covered previously, such as consoles, USB drivers, and
more.
Best of all, you don't have to be a kernel hacker to understand and enjoy this
book. All you need is an understanding of the C programming language and some
background in Unix system calls. And for maximum ease-of-use, the book uses
full-featured examples that you can compile and run without special hardware.
Today Linux holds fast as the most rapidly growing segment of the computer
market and continues to win over enthusiastic adherents in many application
areas. With this increasing support, Linux is now absolutely mainstream, and
viewed as a solid platform for embedded systems. If you're writing device drivers,
you'll want this book. In fact, you'll wonder how drivers are ever written without
it.

About the Authors
Jonathan Corbet got his first look at the BSD Unix source back
in 1981, when an instructor at the University of Colorado let him "fix"
the paging algorithm. He has been digging around inside every system he could
get his hands on ever since, working on drivers for VAX, Sun, Ardent, and x86
systems on the way. He got his first Linux system in 1993, and has never looked
back. Mr. Corbet is currently the co-founder and executive editor of Linux Weekly
News; he lives in Boulder, Colorado with his wife and two children.
Alessandro Rubini installed Linux 0.99.14 soon after getting
his degree as electronic engineer. He then received a Ph.D. in computer science
at the University of Pavia despite his aversion toward modern technology. He
left the University after getting his Ph.D. because he didn't want to write
articles. He now works as a free lance writing device drivers and, um...articles.
He used to be a young hacker before his babies were born; he's now an old advocate
of Free Software who developed a bias for non-PC computer platforms.
Greg Kroah-Hartman has been writing Linux kernel drivers since
1999, and is currently the maintainer for the USB, PCI, I2C, driver core, and
sysfs kernel subsystems. He is also the maintainer of the udev and hotplug userspace
programs, as well as being a Gentoo kernel maintainer, ensuring that his email
inbox is never empty. He is a contributing editor to Linux Journal Magazine,
and works for IBM's Linux Technology Center, doing various Linux kernel related
tasks.
