作者：华清远见嵌入式学院。《Linux设备驱动开发详解》（08&09年度畅销榜TOP50）第4章、Linux内核模块。Linux设备驱动会以内核模块的形式出现，因此，学会编写Linux内核模块编程是学习Linux设备驱动的先决条件。4.1～4.2节讲解了Linux内核模块的概念和结构，4.3～4.8节对Linux内核模块的各个组成部分进行详细讲解，4.1～4.2节与4.3～4.8节是整体与部分的关系。4.9节讲解了独立存在的Linux内核模块的Makefile文件编写方法和模块的编译方法。-Author: HuaQing vision embedded institute. The Linux device driver development "(08 and 09 sep TOP50) annual list of best-selling chapter 4, Linux kernel modules. Linux device driver to the form of kernel modules, therefore, learn to write Linux kernel module programming is learning Linux device driver prerequisite. 4.1 ~ 4.2 explained Linux kernel module of the concept and structure, 4.3 ~ 4.8 Linux kernel modules of the component part of a detailed explanation, 4.1 ~ 4.2 and 4.3 ~ 4.8 day is the relationship between the whole and the parts. Section 4.9 explained the Linux kernel modules are independent of Makefile documents writing methods and module of the compilation approach.
