PCI总线的PDO就会得到PCI配置空间,并从中得到有用信息,如中断号、设备物理内存及I/O端口等信息。 在处理完IRP_MN_START_DEVICE后,驱动程序会将处理结果存储在IRP的设备堆栈中,从I/O堆栈可以取出CM_FULL_RESOURCE_DESCRIPTOR数据结构,从CM_FULL_RESOURCE_DESCRIPTOR中可以取出CM_PARTIAL_RESOURCE_LIST数据结构,而在CM...

...操作系统就是凭着 Vendor ID和Device ID 找到对应驱动程序的。 Class Code:类代码。共三字节,分别是 类代码、子类代码、编程接口。...类代码不仅用于区分设备类型,还是编程接口的规范,这就是为什么会有通用驱动程序。 IRQ Line:IRQ编号。PC机以前是靠两片8259芯片来管理16个硬件中断。
