《Linux设备驱动(第三版)》是一本由Jonathan Corbet、Alessandro Rubini和Greg Kroah-Hartman合著的专业教材,针对Linux初学者全面介绍了设备驱动的原理与实践。该书主要涵盖了以下几个关键知识点: 1. **设备驱动介绍**: - 描述了驱动程序在Linux系统中的核心角色,它们是连接硬件和操作系统内核的关键桥梁。 - 分析了内核的层次结构,包括可加载模块的概念,这些模块允许开发者在运行时添加或替换功能。 - 讨论了设备和模块的分类,以及安全问题,如权限管理和数据保护。 - 提及了版本编号的重要性,以及遵守的版权条款,并鼓励读者参与到内核开发社区。 2. **模块构建与管理**: - 教导读者如何设置测试环境并创建简单的"HELLO WORLD"模块,强调了内核模块与应用程序的区别,如运行环境、并发控制以及内核和用户空间的交互。 - 包括模块编译、加载和卸载的详细步骤,解释了版本依赖性和平台特定代码的需求。 - 内核符号表的使用和预备知识,如初始化和关闭过程中的错误处理以及模块加载的竞争情况。 3. **字符驱动编程**: - 以SCULL(一个简化的字符设备示例)为例,讲解了主次编号系统,以及如何分配和管理设备号。 - 介绍了一些重要的数据结构,如文件操作、文件结构和inode结构,这些都是实现设备驱动的基础。 - 驱动的注册过程被详细阐述,包括scull中的设备注册方法和传统方式。 - OPEN和RELEASE方法的实现,涉及设备打开和关闭的处理逻辑。 - 书中还讨论了内存管理,特别是读写操作,如read方法的实现。 这本书不仅适合希望深入理解Linux设备驱动的程序员,也对系统管理员和硬件工程师提供了实用的指导。通过阅读这本书,读者可以建立起扎实的Linux设备驱动编程基础,适应各种硬件平台的需求。

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.
