linux字符设备驱动程序及其扩展
学习内核相关的东西完整算起来一年半了，不得不说内核的学习是一个学习成本很高的东西，慢慢摸索也逐渐的有了感悟，简单来说，需要如下的几个阶段：
1.基础阶段 （操作系统，C、asm 编程语言，LINUX系统编程）
2.中级阶段 （了解内核架构，API，学习编写内核模块)
3.中高级阶段 （开发独立功能点，驱动程序的学习与编写）
4.高级阶段 （参与内核的开发）
我现在将《Linux设备驱动程序（第3版）》简称LDD3 中内容整理，抽取。由于这本书的内核版本有点老。我就把代码都移植到了我4.0.4的内核上，调通运行，既是自己的 学习也是为了后续同学们学习内核提供点参考资料。考研不易，已是见缝插针，难免有错误疏漏之处还请指正。
