our MD bus_space_probe() extension). This has several side effects: - NuBus drivers must map and unmap slot space, rather than relying on this happening before they are attached. - Functions exported to NuBus drivers from nubus.c now need to be supplied with a bus space tag/handle pair. - Old bus map/peek functions can be garbage collected, as can pmap support for the same. Because of some current limitations of the bus space specification, we are violating the abstraction in grf_mv (NuBus grf driver). All such violations are clearly marked /* XXX */, and must be addressed when the specification is updated. |
