Define a constant for the SuperMac Spectrum/24 series III display card.
Thanks go to Luca Falzoni <falzoni@jetai.unipv.it> for trying out the
code for the Dayna ethernet support.
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.
tweaks and bug fixes by yours truly.
Here's what Denny had to say:
nubus.h:
- add a drsw entry for my card
[ I also added a couple of constants for more display cards ]
if_sn.c:
- allocate sc->space using malloc (Scott wanted this).
- make csr accesses use NIC_PUT/GET, remove sc->sc_csr.
- add multicast and IFF_PROMISC support. multicast isn't
well tested, but I made sure the unicast case still
works.
- finish the new arp interface, remove sc->sc_enaddr
if_snreg.h:
- remove struct sonic_reg
if_snvar.h:
- add NIC_PUT and NIC_GET macros a la if_ae
- remove sc_txhead, it isn't used.
if_sn_nubus.c:
- clean up support for my SE/30 card.
- Move add_nubus_intr from if_sn.c (to keep if_sn.c MI)
if_sn_obio.c:
- make Q610, C610, Q650, C650, Q800 use EXBUS.
- PB500 had a "return" where "break" was intended. PB500
probably wasn't working.
- move add_nubus_intr from if_sn.c.
- add an "explanation" why Apple's ethernet addr is encoded
in token ring format in the PROM.
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.
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.
