Why Is My System Reporting PCIe Gen 1x1 Instead of the Actual PCIe Configuration for My Intel® Arc™ Graphics Card?

Due to the PCIe hierarchy of the Intel® Arc™ Graphics Cards, standard operating system tools such as the Windows* Device Manager and the Linux* console lspci command, will not show the device’s actual PCIe port speed (specifically the PCI max link speed and PCI max link width) information of the graphics device properly. They will always show Gen1 and x1 lanes instead of the expected product information, for example such as Gen4 and x16 lanes for the Intel® Arc™ A770 Graphics card.
There is a hierarchy of PCIe nodes internal to the card. The nodes on top of that stack unfortunately report incorrect values of link attributes, but Intel guarantees the bottom-most bridge reports correct values of those attributes, ones that reflect actual link bandwidth. Those values can be examined with standard tools in Linux like lspci or udevadm (both with the right arguments), or software tools like GPU-Z for Windows.
