| 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.
