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3章、Linux内核及内核编程。由于Linux驱动编程本质属于Linux内核编程，因此有必要掌握Linux内核及内核编程的基础知识。3.1～3.2节讲解Linux内核的演变及Linux 2.6内核的特点。3.3节分析了Linux内核源代码目录结构和Linux内核的组成部分及其关系，并对Linux的用户空间和内核空间进行了讲解。3.4节讲解了Linux 2.6内核的编译及内核引导过程。另外，还描述了在Linux内核中新增程序的方法，驱动工程师编写的设备驱动也应该以此方式被添加。3.5节讲解了Linux下C编程的命名习惯以及Linux所使用的GNU C针对标准C的扩展语法。-Author: HuaQing vision embedded institute. The Linux device driver development "(08 and 09 sep TOP50) annual list of best-selling chapter 3, Linux kernel and the kernel programming. Because Linux driver programming essence belongs to the Linux kernel programming, so it is necessary to master the Linux kernel and the kernel of the basic knowledge of programming. 3.1 ~ 3.2 explain the evolution of the Linux kernel and Linux 2.6 kernel characteristic. Section 3.3 the Linux source code analysis kernel directory structure and Linux kernel part of the relationship, and Linux and the user space and the kernel space explained. Section 3.4 explained the compilation of the 2.6 kernel Linux kernel and guide process. In addition, also describes in Linux kernel method of new programs, drive engineer of the device driver should write in this way be added. Section 3.5 explained under Linux C programming naming conventions and Linux use the GNU C ? for standard
