drivers to protect DDB from being invoked while the console is in
process-controlled (i.e., graphics) mode.
Implement the logic to use this hook from within pcvt. (I'm sure
Søren will do the syscons part RSN).
I've still got one occasion where the system stalled, but my attempts
to trigger the situation artificially resulted int the expected
behaviour. It's hard to track bugs without the console and DDB
available. :-/
warnings and are cosmetic only. Poul once requested them, but neither
Sean nor Søren commented on them, so i commit it now before it's
getting lost some day.
card. This is the braindamaged card with the 80186 CPU on it. It is
slow, probably not very good after all, but hey, if you have one lying
around doing nothing anyway...
Added the "zp0" driver to GENERIC.
will cause kernel compiles to work even if the src/includes directory
doesn't exist but still do the 'Right Thing' and pull files from the
source tree if it does exist.

#179). The fix implements a ttyhalfclose() (sort of), resetting the
session and pgrp pointers when the physical device is about to be
closed.

old type (stty) ioctls can easily bypass locking bits.
It involves manual conversion from old ioctls to new ones,
large piece of code duplicated from tty_compat.c
after ttioctl too, because it can change t_line.
Remove (TS_CNTTB | TS_LNCH) test, it is always inherits from
old tty mode and can't be reach in currently setted mode.
o the includes are now properly done by <sys/foo.h> instead of "foo.h"
o a bunch of undeclared functions has been resolved
o pcvt finally supports devconfig
When attempting to abort a command, don't assume that just because the
sequecer happens to have SCBPTR pointing at the scb we want that it is
an active command.
- catch the interrupt type (EDGE/LEVEL) before chip reset instead
of guessing the right type.
- Add pause variable to the ahc struct to better handle the different
interrupt types and pausing the sequencer.
- CLRINTSTAT -> CLRSCSIINT: This is a documented bit in the CLRINT
register in newer Adaptec documentation, so use their name for it.
- Report valid residual byte counts.
- Don't mess with the target scratch areas > id 8 on single, narrow,
channel devices. The BIOS does a checksum of this area and can
flip out if we zero it out.
- Initialize the sequencer FLAGS scratch ram variable in the single
channel devices to 0. This was the cause of the annoying warning
where we would get a cmdcmplt the first time we did any type of
transfer negotiation with no valid scb. It also fixes the problem
that looked like the INTSTAT register wasn't clearing fast enough.
This only showed up on 294x cards, not motherboard aic7870s.
- Add the AHC_AIC7870 type and use it as the superset of aic7870
based controllers.
- clear the sync offset section of the targ scratch area so that
we default to asyncronous transfers. This was only a problem
for wide controllers because there was a scenario where the
offset wouldn't get updated before a data(out/in) phase would
occur. This required some change in the sequencer code since we
were depending on this field to hold the rate to negotiate.
- allow sync and wide negotiated commands to be tagged (the sequencer
now handles this properly).
I'm not exactly sure why all the inb/outw stuff got added to netboot.h
and I'd be happy if someone like Martin or Bruce could take a look at it!

Etherlink III 'zp' on 2.0R, but it did not work with the -current.
Noriyuki Takahashi <hor@aecl.ntt.jp> san has fixed this bug.
Our alpha-testers are tested this driver with 3C589B-COMBO and
3C589B-TP. And it works fine.
I also fixed a little about the use of ZP_DEBUG symbol and beautified
the awful Frankenstein-style indent :-) with "indent -c0 -nfc1 -i4".

update what has actually been touched. This should speed up
screen access on slow hardware.
Introduced setting of "destructive" cursor size, much like
the old hardware cursor.
