${PORTSDIR}. This undoes the changes done in rev. 1.38 and 1.59
(part of the bsd.port.mk pre-dawn ages I've never understood).

(2) Add new variable NO_IGNORE that will override any IGNORE causes.
This is just a little hack to allow building of REQUIRES_MOTIF
ports and its dependencies only etc., so don't document it.
(3) Update +REQUIRED_BY files as necessary. Now you should be able to
delete ports that have runtime dependencies without pkg_delete
complaining about this file missing.
Add auto-termination support as well as support for setting the high byte
termination. Booting with '-v' will display the settings that the driver
chose. If you stick narrow devices onto the external wide port, you had
better make sure that your converter cable terminates the bus, you have a
wide device on there that terminates the bus, or you manually set the
termination properly in SCSI-Select instead of using "Automatic". The
code will get the setting right regardless if you *don't* have internal
wide devices in this type of configuration. Unfortunatly this is a limitation
of the design of the Adaptec cards.
Style nit. Backslashes in macro weren't aligned.
aic7xxx.c:
Preserve the value of STPWEN in SXFRCTL1 during initialization. STPWEN
controls low byte termination and is setup by the PCI probe front end.
SDONE, not HDONE.
In the data phase dma handler, mask off just the enable bits instead of
clearing the whole register. Clearing the direction bit could be bad.
Also don't stop a DMA until MREQPEND goes false. Doing this may cause
an ABORT on the PCI bus although I have yet to see this happen.
Add definitions for MREQPEND and the BRDCTL register. The BRDCTL register
is used to handle high byte termination and automatic termination testing.
at the time, but on further reflection..." bucket with these changes.
1. Checking the media before frobbing the disks was a fine idea, and
I wish it could have worked, but that leads to a rather difficult
situation when you need to mount the media someplace and you're about
to:
a) Chroot away from your present root.
b) Newfs the root to be.
You're basically screwed since there's no place to stick the mount
point where it will be found following the newfs/chroot (and eliminating
the chroot in favor of just using the "root bias" feature would work
great for the distributions but not the pkg_add calls done by the
package installer).
2. Automatic timeout handling. I don't know why, but alarm() frequently
returns no residual even when the alarm didn't go off, which defies
the man page but hey, since when was that so unusual? Take out timeouts
but retain the code which temporarily replaces the SIGINT handler in
favor of a more media-specific handler. This way, at least, if it's hanging
you can at least whap it. I think the timeout code would have been losing
over *really slow* links anyway, so it's probably best that it go.
This should fix NFS, tape & CDROM installs again (serves me right for getting
complacent and using just the FTP installs in my testing).
Disabling npx0 works right now.
Don't reference `npxdriver' if npx0 is not configured. Not configuring
npx0 doesn't quite work yet.
Don't clear potential non-npx pcb flags in setregs().
bell type on boot. Slightly annoying when your system doesn't have a speaker.
This adds a `keybell' frob for setting it. Closes PR#2519

character of the argument being processed isn't '\0'.
This fixes problem with backgammon exiting abnormally when you answer 'y' to
the question it asks if you need instruction for the game.
2.2 cnadidate, maybe?
should be nearly impossible to overflow the QOUTFIFO (worst case 9 command
have to complete with at least 6 of them requiring paging on an aic7850),
so don't take the additional PIO hit to guard against this condition. If we
don't see our interrupt in time, the system has bigger problems elsewhere.
If this ever does happen, the timeout handler will notice and retry the
command.
Remove the ABORT_TAG sequencer interrupt handler. This condition can't happen
with the new SCB paging scheme.
Fix a few bugs noticed by Dan Eischen <deischen@iworks.InterWorks.org>
that could prevent ULTRA from being negotiated to drives above ID 7 and
also could allow an SCB to be passed to ahc_done twice during error recovery.
Fix a bug notice by Rory Bolt <rory@atBackup.com>. It turns out that a
sequencer reset will actually start the sequencer running regardless of the
state of the pause bit. This could lead to strange problems with loading
the sequencer.
Only enable reselections once the channel and SCSIRATE have been cleared.
Add a pause block around the test busy code in the non-tagged case to simplify
error recovery in the corner case of aborting an SCB that just got started.
Simplify reselection processing by removing the call to initialize_scsiid.
Clear the scsiseq re/select control bits and setup for catching bogus
busfrees earlier in the re/select process.
Improve the automatic PIO code. It turns out that SPIORDY is not a reliable
hardware condition bit, so use REQINIT intstead. Don't rely on PHASEMIS
either since it can take too long to come true. Use a brute force comparison
instead.
Remove some unnecessary overhead in the command complete processing. It
should be nearly impossible to overflow the QOUTFIFO (worst case 9 command
have to complete with at least 6 of them requiring paging on an aic7850),
so don't take the additional PIO hit to guard against this condition. If we
don't see our interrupt in time, the system has bigger problems elsewhere.
If this ever does happen, the timeout handler will notice and retry the
command.
not lazy-fault page table pages. Update the copyout support to take
that into account. This should fix some segfault problems on such
machines.
After a short test period, we'll move this into 2.2.
