OpenBSD/hppa runs on a large set of the 32-bit Hewlett Packard Precision
Architecture workstations and servers (HP PA-RISC). A subset of the 64-bit
models are supported in 32-bit mode, as well.
<p>
A mailing list dedicated to the OpenBSD/hppa port is available at
<u><font color="#23238e">hppa@openbsd.org</font></u>.
To join the OpenBSD/hppa mailing list, send a message body of <b>"subscribe
hppa"</b> to <a href="mailto:majordomo@openbsd.org">majordomo@openbsd.org</a>.
Please be sure to check our <a href="mail.html">mailing list policy</a> before

<p>
The current port maintainer is
Mark Kettenis (<a href="mailto:kettenis@openbsd.org">kettenis@openbsd.org</a>).

<h3><font color="#0000e0"><strong>History</strong></font></h3>
<p>
This project was started in those days when the only
open source operating systems for HP PA-RISC computers were
<a href="http://www.cs.utah.edu/projects/flux/lites/html">Lites</a> and
<a href="http://www.mklinux.org">MkLinux</a>.
These two sources were a major supply of information and
code for initial development of the OpenBSD/hppa port.
<a href="http://www.cs.utah.edu/~mike/hpbsd/hpbsd.html">HPBSD</a>
is encumbered by HP proprietary code and USL licensing and is
not publicly available.
One of the major direct benefits from previous porting efforts
(besides the code, of course) was support for HP PA-RISC in GCC and
binutils, which allowed quick building of a cross-tools environment
for development.
<p>
Later on, Hewlett-Packard decided to sponsor a
<a href="http://www.parisc-linux.org/">Linux</a> port to the PA-RISC
family, which actually resulted in some proprietary documentation
being released, even though their target was a different class of 9000
machines back then.
<a name="status"></a>
<h3><font color="#0000e0"><strong>Current status</strong></font></h3>
<p>
Currently, all the supported systems boot multi-user.
In addition to the release, full snapshots are made periodically,
and work is ongoing to provide better hardware support.
<p>
OpenBSD/hppa contains some limited (for now) support for running
HP-UX binaries via the <strong>COMPAT_HPUX</strong> kernel option.
Work is in progress to improve this support.

</ul>
<p>
<sup>*</sup>Support for these models was added after OpenBSD 4.2 was released.
<p>
<h4>Unsupported systems and devices</h4>
The following systems are unsupported, but may eventually be coaxed to life.
<ul>
<li>PA7000-based: 705, 710, 720, 730, 750
<li>PA7100LC-based: Dx00, Dx10
<li>PA7200-based: Dx50, Dx60
<li>PA8000-based(in 32-bit mode): Dx70, Dx80/R380, Kx50/Kx60
<li>PA8200-based(in 32-bit mode): D390/R390, Kx70/Kx80
<li>HP 9000 E-Class (with limited I/O)
<li>Hitachi VQ200, VQ210, and some other non-HP workstations
<li>Hitachi 9000V 3050RX/* workstations and 3500/* servers
<li>HP VME and VXI single board systems (requires VME at least)
</ul>
<p>
The following systems are very unlikely to be supported since they either have
incompatible firmware (the 3000s) or almost completely undocumented I/O
subsystems (the 8x7s).
<ul>
<li>HP 3000 900
<li>HP 9000 8x7 (F, G, H, I-Class)
</ul>
Even though some 64-bit systems are supported by this port in 32-bit mode,
the following models cannot be supported due to the I/O system limitations
and can only run the
<a href="hppa64.html">OpenBSD/hppa64</a> port:
<ul>
<li>PA8500-based: A400/rp24x0, L1000/L2000
<li>PA8600-based: A400/rp2450, L3000/rp5400
<li>PA8700-based: A500/rp2470, N4000/rp74x0, rp8400
<li>PA8800-based: A500-9x, C8000, rp3410, rp3440, rp4440, rp7420, rp84x0
</ul>
<p>
These Convex systems are NUMA supercomputing clusters
consisting of one or more 8-way SMP nodes with PA7100 or PA7200 CPUs.
They are very unlikely to be ever supported.
<ul>
<li>Convex Exemplar SPP1000/{CD,XA}
<li>Convex Exemplar SPP1200/{CD,XA}
<li>Convex Exemplar SPP1600/{CD,XA}
</ul>
<p>
These systems will, probably, never be supported by this port since
they are of 1.0 PA-RISC architecture, which is substantially
inferior to the 1.1:
<ul>
<li>HP 9000 600, 635, 645
<li>HP 9000 800, 808, 810, 815, 822, 825, 832, 834, 835, 836, 840
<li>HP 9000 842, 844, 845, 846, 850, 852, 855, 860, 865, 870, 890
<li>HP 9000 900, 920, 922, 925, 930, 932, 935, 948, 949, 950,
<li>HP 9000 950S, 955, 958, 960, 980, 990, 992
</ul>
<p>
<h4>Unsupported peripherals</h4>
<p>
This list is not meant to be exhaustive either, but sums up the most commonly
encountered devices on hppa machines.

<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=dino&sektion=4&arch=hppa">dino(4)</a> Dino in card mode.

<li>VME controller
