PCIe Switch Driver RRS feed

  • Question

  • Hi All,

    I am looking for better solution.

    I am working on PCIe Switch, which has one up stream and one down stream. The up stream is capable of addition logic, which does various diagnostic functionality on the end point and also monitors the PCIe bus data. Up stream also generated MSI on behalf of diagnostic functionality.

    The PCIe driver we developed when installed on the PCIe UP stream by replacing pci.sys, the down streams and the end point becoming invisible. We can see the device in device manager as hidden device.

    Can I install any other driver on top of the UP stream by replacing default pci.sys driver. 

    The driver I am installing shall be capable of discovering it child's and register with WDF (WdfFdoAddStaticChild).

    Can I get any reference to bus driver 

    Thanks in advance.

  • Are you attempting to replace the PCI driver for all devices, or are you specifying your driver only for your device?
