2023-11-14 Thread Mario Limonciello
USB4 routers support a feature called "PCIe tunneling". This allows PCIe traffic to be transmitted over USB4 fabric. PCIe root ports that are used in this fashion can be discovered by device specific data that specifies the USB4 router they are connected to. For the PCI core, the specific
