I don't think you need to go that far, unless you see a significant likelihood think that such a computer might be created one day. This depends on how hard and risky such a change is, of course. But the current driver's userspace interface should at least anticipate the possibility, so you aren't trapped into a weird or non-back-compatible interface in the future. So for now you might choose to do something as simple as renaming /config/pcie-gadget to /config/pcie-gadget0 and leave it at that. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
