I don't think this would work. Currently, the interrupt-map associates the interrupts with the PCI-to-PCI bridges, i.e devices 00:01, 00:02, 00:03, 00:04, 00:05, etc. The real PCIe devices themselves are at 01:00, 02:00, 03:00, 04:00, 05:00. Each of them sit on a different bus, at devfn = 0. So if I ignore the bus number, how could the PCI code find what is the matching interrupt?
