用Visual studio2012在Windows8上开发内核驱动监视线程创建

在Windows NT中，80386保护模式的“保护”比Windows 95中更坚固，这个“镀金的笼子”更加结实，更加难以打破。在Windows 95中，至少应用程序I/O操作是不受限制的，而在Windows NT中，我们的应用程序连这点权限都被剥夺了。在NT中几乎不太可能进入真正的ring0层。 
在Windows NT中，存在三种Device Driver：

  1．“Virtual device Driver” (VDD)。通过VDD，16位应用程序，如DOS 和Win16应用程序可以访问特定的I/O端口（注意，不是直接访问，而是要通过VDD来实现访问）。

  2．“GDI Driver”，提供显示和打印所需的GDI函数。

  3．“Kernel Mode Driver”，实现对特定硬件的操作，比如说CreateFile, CloseHandle (对于文件对象而言), ReadFile, WriteFile, DeviceIoControl 等操作。“Kernel Mode Driver”还是Windows NT中唯一可以对硬件中断和DMA进行操作的Driver。SCSI 小端口驱动和 网卡NDIS 驱动都是Kernel Mode Driver的一种特殊形式。

 

 

Visual studio2012与Windows8带来格外不同的新体验

 

1.启动Vs2012

2.看见满目的驱动开发模板

3.选择一个驱动模式，有内核模式与用户模式两种的驱动

 

4.创建一个驱动程序，KMDF DriverMVP

 

5.我们选择的是内核模式的驱动程序，下面是创建成功后的界面，分别是驱动程序本身，与驱动安装包

6.按下F5，选择驱动编译，

 

插入下列代码实现ring0层驱动监视创建线程，请见代码分析
