For standard pci, you have to make something up anyway - for shpchp we just use an incremental number and combine it with the bus number to represent the slot. For pcie, you can get this info from the slot capabilities register. - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
