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.
indirect bus code framework) from Jason Thorpe. This allows us to dump
bus_scan() and bus_print(), and move bus_peek() and bus_mapin() to the
NuBus code (since they'll eventually go away, anyway).
second argument. The NuBus autoconfig code had to be reorganized as a
result of this, and looks much more like a directly-attached bus now.
These changes eliminate __BROKEN_INDIRECT_CONFIG.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
Also change the device probing scheme to use something a bit more rational.
A current side-effect is that nubus cards are double-mapped. I expect
to fix that shortly.
Also change splclock() to block everything but serial hardware interrupts.
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
use config.new.
Numerous updates to console so it works better on the SE/30 screen.
Some nice changes from Brad Parker for handling NuBUS and an ethernet
driver that I haven't worked on, yet.
