[讨论][求助]PCIE过滤驱动如何开发

PS E:\> .\devcon.exe stack "PCI\VEN_****&DEV_0010"PCI\VEN_****&DEV_0010&SUBSYS_00000000&REV_10\4&39FF1125&0&0009    Name: PCI Configuration Filter Driver for VEN_****&DEV_0010    Setup Class: {4d36e97d-e325-11ce-bfc1-08002be10318} System    Controlling service:        PciConfig    Lower filters:        PciConfigROOT\SYSTEM\0002    Name: PCI Configuration Filter Driver for VEN_****&DEV_0010    Setup Class: {4d36e97d-e325-11ce-bfc1-08002be10318} System    Controlling service:        PciConfig    Lower filters:        PciConfig2 matching device(s) found.我电脑插入了一块pcie switch板卡，默认驱动是pci.sys我想在pci.sys驱动上安装一个过滤驱动，即上面的PciConfig，这个过滤驱动的功能主要是去读写pci配置和bar空间的操作。但是感觉安装后显示如上图所示。原来的pci.sys不见了。devcon.exe driverfiles又可以看到pci.sys，如下
PS E:\> .\devcon.exe driverfiles "PCI\VEN_****&DEV_0010*"PCI\VEN_****&DEV_0010&SUBSYS_00000000&REV_10\4&39FF1125&0&0009    Name: PCI Configuration Filter Driver for VEN_****&DEV_0010    Driver installed from C:\WINDOWS\INF\oem31.inf [PciConfig_Device]. 2 file(s) used by driver:        C:\WINDOWS\system32\DRIVERS\PciConfig.sys        C:\WINDOWS\system32\DRIVERS\pci.sysROOT\SYSTEM\0002    Name: PCI Configuration Filter Driver for VEN_****&DEV_0010    Driver installed from C:\WINDOWS\INF\oem31.inf [PciConfig_Device]. 2 file(s) used by driver:        C:\WINDOWS\system32\DRIVERS\PciConfig.sys        C:\WINDOWS\system32\DRIVERS\pci.sys2 matching device(s) found.
