Well, not physical in a sense that you can look at the wires, but commonly it has a number of interface attributes which match the capabilities of the the host bridge and some more platform specific things, eg the firmware's autoconfiguration support. > There is > other precedent for things in the autoconf tree that do not correspond > to anything physical, such as wsdisplay Yes, devices in the autoconf tree are connected by interfaces (named by interface attributes) which are primarily APIs. Sometimes they correspond to some physical bus semantics, sometimes it is just a software abstraction. Anyway - the interface attributes of "mainbus" are fixed by the platform which makes it a bad choice to attach random MI things at. best regards Matthias ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
