OOPS, we are doing it with "uses MAINBOARD_SUBSYSTEM_ID" and if I am right every on board device share the same ID. For devices who want its own ID it has to implement the .set_subsystem method. This is really ugly. IMHO, we should treat the subsystem ids as attributes of PCI device and it should be defined in the mainboard config file. It should look like this device pci 0.0 on vendor 0x1234 device 0x5678 end or device pci 0.0 on register "subsystem_vendor_id" = "0x1234" register "subsystem_device_id" = "0x5678" end and the PCI enumeration code will call the generic pci_set_subsystem() function to set subsystem ID for every PCI device. For those device with subsystem ID unspecified, it is default to zero any.
