请问:WDM的PCI驱动如何获得bus,slot信息?

rt

可以用下面的函数获得板卡的（物理）Bus slot号

IoGetDeviceProperty()
Param: DeviceProperty = DevicePropertyUINumber

This number is typically a user-perceived slot number, such as a number printed next to the slot on the board,or some other number that makes locating the physical device easier for the user. If the device is on a bus that has no UI number convention, or if the bus driver for the device can't determine the UI number, this value is 0xFFFFFFFF.
