Basically, there're 2 types of PCI bus sensitive PEs: (A) The PE includes single PCI bus. (B) The PE includes the PCI bus and all the subordinate PCI buses. At present, we'd like to put PCI bus originated by PCI-e link to form PE that contains single PCI bus, and the PCIe-to-PCI bridge will form the 2nd type of PE. We don't figure out to detect PLX bridge yet. Once we can detect PLX bridge some day, we have to put PCI buses originated from the downstream port of PLX bridge to the 2nd type of PE. The patch changes the original implementation for a little bit to support 2 types of PCI bus sensitive PEs described as above. Also, the function used to retrieve the corresponding PE according to the given PCI device has been changed based on that because each PCI device should trace the directly associated PE.
