Linux Device Drivers

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

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.

Об авторе (2005)

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 (http: //LWN.net/); he lives in Boulder, Colorado with his wife and two children. Alessandro 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 lancer 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.

Book description

This book is for anyone who wants to support computer peripherals under the Linux operating system or who wants to develop new hardware and run it under Linux. Linux is the fastest-growing segment of the UNIX market and is winning over enthusiastic adherents in many application areas. This book reveals information that heretofore has been passed by word-of-mouth or in cryptic source code comments, showing how to write a driver for a wide range of devices. You don’t have to be a kernel hacker to understand and enjoy this book; all you need is an understanding of C and some background in UNIX system calls. Drivers for character devices, block devices, and network interfaces are all described in step-by-step form and are illustrated with full-featured examples that show driver design issues, which can be executed without special hardware. For those who are curious about how an operating system does its job, this book provides insights into address spaces, asynchronous events, and I/O. Portability is a major concern in the text. The book is centered on version 2.0, but also covers 1.2.13 and experimental versions up to 2.1.43. You are also told how to maximize portability among hardware platforms. Contents include:

  • Building a driver and loading modules
  • Complete character, block, and network drivers
  • Debugging a driver
  • Timing
  • Memory management and DMA
  • Interrupts
  • Portability issues
  • Peripheral Component Interconnect (PCI)
  • A tour of kernel internals
