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.

<h3 id="history"><strong>History</strong></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/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.
|
|
|
|
<h3 id="status"><strong>Current status</strong></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.

<h4>Unsupported systems and devices</h4>
|
|
|
|
The following systems are unsupported, but may eventually be coaxed to life.
|
|
Some of them will boot OpenBSD, but there is not enough device support for
|
|
OpenBSD to be really useful on them.
|
|
<ul>
|
|
<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>Most Hitachi PA-RISC workstations and servers
|
|
</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:
|
|
<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, rp4410, rp4440, rp7420, rp84x0
|
|
<li>PA8900-based: C8000, rp3410, rp3440, rp4410, rp4440, rp7420, rp84x0
|
|
</ul>
|
|
|
|
<p>
|
|
Convex PA-RISC systems (NUMA supercomputing clusters
|
|
consisting of one or more 8-way SMP nodes with PA7100 or PA7200 CPUs)
|
|
are unlikely to be ever supported.
|
|
|
|
<p>
|
|
All other HP 9000 6xx, 8xx and 9xx server 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.
|
|
|
|
<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.
|
|
<ul>
|
|
<li><a href="https://man.openbsd.org/hppa/dino.4">dino(4)</a> Dino in card mode.
|
|
<li><a href="https://man.openbsd.org/hppa/pcmcia.4">pcmcia(4)</a> PCMCIA adapters.
|
|
<li><a href="https://man.openbsd.org/hppa/mongoose.4">mongoose(4)</a> EISA bus adapter.
|

<li>VME controller
|
|
<li>Any HP-PB devices
|
|
<li>On-board floppy controller
|
|
<li>Dino's PS/2 keyboard and mouse controller
|
