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.
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
function, and kill any locally-defined print function.
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).
- When finished writing, if the SCSI bus has BSY asserted, write another
byte to the SBC to ensure we get an interrupt.
- Unflag SCSI interrupts on the VIA whenever we clear the interrupts
on the SBC itself.
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.
a condition that occurs with some slow SCSI devices when they disconnect
(e.g. the AppleCD 600), generating spurious selection interrupts.
- Reorganize the debugging code slightly.
