Hi All,
I am working on PCIe Switch ( gen3 to gen4) driver. The PCIe switch has one up stream and down stream port. Also the UP Stream is capable of handling MSI and INTX.
I could develop the PCIe Switch driver with MSI support, but the issue I am observing is ,
when I install the PCIe Bus driver, the device connected on the down stream port is not visible to device manager. Also I could not able to install the default driver of the device. The device can be found if device manager searched for hidden devices. Also the PCIe device can be found with PCIe utilities.
if the same device is connected with out above PCIe switch driver, it is visible to the device manager ( In this case, Windows assigns pci.sys driver to UP stream port ).
I would like to understand from community, what i need to do additional things in my PCIe switch driver ( PCIe Bus Driver) so that devices are also visible to the device manager.
Thanks
