OpenBSD/hppa

Over the last few weeks I've made some important improvements to the
OpenBSD/hppa port.  Support for newer B/C/J-class workstations was
added, and basically anything but the C8000 should just work.  I've
also fixed a rather critical bug, which makes machines with a PA-7200
CPU usable again (and makes machines with other CPU's much more
stable).  And last but not least, support for the NCR 53C720 Fast-Wide
SCSI found on many hppa machines has been added to siop(4).

With all these changes, I have reason to believe that most of the so
far unsupported D-class and K-class servers should just work, or will
work with just a small tweak to the code here and there.
Unfortunately I don't have such hardware myself, so if people have
access to one of these machines, could they give the latest snapshot a
go on them and send me (and [email protected]) a copy of the dmesg?

Thanks,

Mark
