a serial console; the direct driver didn't care, but the MRG driver
wouldn't probe ADB when using a serial console. Remove the check from
the MRG version of the code to resolve this difference.
funk when they misbehave and give us unexpected results. Specifically:
- Don't assume that the first free slot is at the top of the table if
we can't find one.
- Don't increment ADBNumDevices when backfilling "holes" left by devices
that didn't respond to a TALK R3 during the initial device scan.
- Don't assume that an address reassignment worked; make sure something
responds on the new address before plowing forward.
- If after device reassignment there are no free slots, make sure to
indicate this fact.
- Failing all else, handle the situation where we run out of slots in
the device table -- which now should "never" happen -- gracefully.
While the Power Manager driver still sometimes misbehaves, it shouldn't
cause the system to crash/hang due to us walking off the end of the
device table.
with volatile. The bug didn't show its face until more agressive
optimization showed up, apparently a result of the last egcs upgrade.
(The interrupt handling changes from June have certainly also played
a part.) Thanks to Ken'ichi Ishizaka for discovering the problem.
- Add initial IOP support. ADB doesn't work yet for me, but it's here so
that others will be encouraged to work on it. ADB_HW_IOP basically
is configured as a NOP so that serial consoles will continue to work.
- Roll via1_intr and via2_intr into the intr.c scheme--this also required
changing rtclock_intr to grovel the stack differently so that hardclock
gets the right arguments and softclock() doesn't get all reentrant.
- Make via1 interrupts parallel to via2 interrupts--handlers get a pass-
through pointer and we can register handlers. Register via1 interrupt
with intr_establish()--normally level 1, level 6 for A/UX scheme.
- Use intr_establish() to set real via2 interrupt handler instead of the
hacked function pointer.
- Reorganize adb-direct interrupts so that a function call is removed.
- Implement A/UX interrupts for all Quadras right now. We may need to
special case some Quadras, but Linux folks are reporting success on
several models.
- Fix intrnames to be accurate for the normal, PSC, and A/UX interrupt
configurations.
- Make it compile again, with BPF.
- Don't subtract the Ethernet header length from the total packet length.
- Copy the alignment fix from sys/dev/ic/i82586.c (though the m68k shouldn't
really be affected).
directly, call the function pointer (*if_input)(ifp, m). The input routine
expects the packet header to be at the head of the packet, and will adjust
as necessary. Privatize the layer 2 input and output routines, allowing
*_ifattach() to set them up as appropriate.
of the buffer you're copying from as the loop interator, not the length
of the buffer you're copying to. Also, rewrite print_single() with
pointer instead of array operators. Appears to correct some ADB-related
`hangs' during autoconfig.
