linux kernel
This is, on the surface, a book about writing device drivers for the Linux system.
That is a worthy goal, of course; the flow of new hardware products is not likely to
slow down anytime soon, and somebody is going to have to make all those new gadgets
work with Linux. But this book is also about how the Linux kernel works and
how to adapt its workings to your needs or interests. Linux is an open system; with
this book, we hope, it is more open and accessible to a larger community of developers.
This is the third edition of Linux Device Drivers. The kernel has changed greatly
since this book was first published, and we have tried to evolve the text to match.
This edition covers the 2.6.10 kernel as completely as we are able. We have, this time
around, elected to omit the discussion of backward compatibility with previous kernel
versions. The changes from 2.4 are simply too large, and the 2.4 interface
remains well documented in the (freely available) second edition.
This edition contains quite a bit of new material relevant to the 2.6 kernel. The discussion
of locking and concurrency has been expanded and moved into its own
chapter. The Linux device model, which is new in 2.6, is covered in detail. There are
new chapters on the USB bus and the serial driver subsystem; the chapter on PCI has
also been enhanced. While the organization of the rest of the book resembles that of
the earlier editions, every chapter has been thoroughly updated.
We hope you enjoy reading this book as much as we have enjoyed writing it.
