While the latter half of the sentence is true, Xen may know of PCI devices be other means. It scans the bus itself after all on x86, under certain conditions. Furthermore "pci-passthrough" is an Arm-only option, when the change here affects x86 as much. The description therefore will need some improvement; the code change itself is okay (on the assumption that it can be justified properly). Jan
