<h3 id="history"><strong>History:</strong></h3>
<p>
The original port was made for NetBSD by Eduardo Horvath and released for
the first time in January 1999.
The porting to OpenBSD started in August 2001 and in the end of September the
first binary snapshot was released. The porting was done mainly by Jason
Wright and Artur Grabowski and was done on both SBus and PCI machines so that
a decently wide range of hardware support was ready even before the system
could boot multiuser.
<p>
OpenBSD 3.0 was the first official release of OpenBSD/sparc64, and since
that release support for many more devices has been added (including
devices required for X11R6 support). The other architectures that
OpenBSD supports have benefited because some kinds of bugs are
exposed more often by the 64-bit big endian nature of UltraSPARC.
<p>
Sun refused access to the necessary documentation for the (very bizarre)
host bridge and caches in the UltraSPARC III machines, so a few years were
lost before some reverse engineering figured out the changes in these
machines (and the undocumented processor bugs, too). In 2007, Sun
<a href="#hwdocs">was finally convinced</a> to release the missing
information, and development progress became more rapid.
<p>
OpenBSD 4.0 was the first release to ship with support for the
UltraSPARC III based machines; OpenBSD 4.3 first with SMP support, and
OpenBSD 4.4 has been the first to support the UltraSPARC IV,
UltraSPARC T1, UltraSPARC T2, SPARC64-V, SPARC64-VI and SPARC64-VII
processors. OpenBSD 5.7 has been the first to support the SPARC T3,
SPARC T4, SPARC T5, SPARC M5, SPARC M6 and SPARC64-X processors.
<p>
And since there are always little bits missing, work is continuing...
<hr>
<h3 id="status"><strong>Current status:</strong></h3>
<p>
Currently most of the hardware available to the developers boots
multiuser and supports enough of the on-board devices to be generally
usable.
<p>
The X Window System is supported on most systems.
Accelerated drivers are available for ATI graphics adapters, Tech
Source graphics adapters and the UPA Creator, Creator 3D and Elite 3D.
It is possible to use X in frame buffer mode with all supported SBus
cards, as well as the on-board ATI graphics, the UPA Creator,
Creator 3D or Elite 3D, and the Expert 3D at the boot resolution/depth
using either the wsfb(4) or the wildcatfb(4) driver.

<p>
OpenBSD 4.4 may trigger a hardware fault on the SPARC Enterprise
M4000/M5000/M8000/M9000 that can only be cleared by a field engineer.
A workaround for this problem is available in OpenBSD 4.5 and later.
<p>
The PRIMEPOWER 650/850 machines are only supported with SPARC64-V CPUs.
<p>
The Fujitsu M10 and M12 machines have only been tested with OpenBSD
running in a logical domain.
<p>
Please note, some machines like the Ultra1, Ultra2, Enterprise 220R
and SPARC Enterprise T5120/T5220 may require upgrading the flashprom
before OpenBSD can be successfully installed. The SPARC Enterprise
T5120/T5220 needs at least OBP 4.28.0.
On machines like the Oracle SPARC T4-2, older firmware versions from
around 2011 are known to cause kernel panics and crashes in
<a href="https://man.openbsd.org/sparc64/ldomd.8">ldomd</a>; later
versions, at least SysFW 8.9.11 from 2018, are known to work.

Most of these machines will almost certainly just work. If you have
one of these machines available for testing, please give it a try and
tell us about the result.
<h4>Unsupported machines</h4>
<p>
The following machines do not run OpenBSD/sparc64 just yet:
<ul>
<li>Fujitsu HALstation 330/350/375/385
<li>Fujitsu S-7/300
<li>Fujitsu GP7000F Model 200/400/600/1000/2000
<li>Fujitsu PRIMEPOWER 200/400/600/1000/2000 (with SPARC64-IV CPUs)
<li>Fujitsu SPARC Enterprise M3000
<li>Sun SPARC Enterprise M3000
</ul>
<p>
OpenBSD may trigger a hardware fault on the SPARC Enterprise M3000.
With older versions of the firmware, this fault can only be cleared by
a field engineer. Make sure you update the firmware before trying to
run OpenBSD on these machines. Firmware XCP 1116 and later are known
to allow end users to clear the fault themselves. There is no
evidence that running OpenBSD actually damages the hardware.
<h4>Unsupported devices</h4>
<ul>
<li>SBus cards other than those listed above.
<li>PCI video cards other than those listed above.
</ul>

<h3 id="hwdocs"><strong>Hardware documentation:</strong></h3>
<p>
Previous to 2007, it was extremely difficult or impossible to get much of
the necessary hardware documentation for these machines. Members of our
team (in particular David Gwynne) were instrumental in pressuring and
convincing Sun to go back into their archives and dig up the data sheets
that they had written in-house, describing the operation of their chips to
their own engineers. These documents can now be found at
<a href="http://web.archive.org/web/20111209011516/http://wikis.sun.com/display/FOSSdocs/Home">
http://wikis.sun.com/display/FOSSdocs/Home</a>.
Some documents are still missing at that site, so we ask that interested
developers contact Sun and request additional information.

<strong>Getting and installing OpenBSD/sparc64:</strong>
</h3>
<p>
The latest supported OpenBSD/sparc64 release is
<a href="73.html">OpenBSD 7.3</a>.
Here are the
<a href="https://ftp.openbsd.org/pub/OpenBSD/7.3/sparc64/INSTALL.sparc64">
OpenBSD/sparc64 installation instructions</a>.
<p>
Snapshots are made available from time to time, in
<a href="https://cdn.openbsd.org/pub/OpenBSD/snapshots/sparc64">this location</a>
as well as on a few
<a href="ftp.html">mirrors</a>.
Here are the
<a href="https://ftp.openbsd.org/pub/OpenBSD/snapshots/sparc64/INSTALL.sparc64">
OpenBSD/sparc64 snapshot installation instructions</a> as well.
<p>
There are several installation media provided, so that
OpenBSD/sparc64 can be installed or upgraded via CD, floppy boot images on
some models, miniroot images for machines without floppies,
as well as network and diskless installs.
<ul>
<li><strong>CD image</strong> (install73.iso)
<p>
Booting off a CD provides a small ffs filesystem with a kernel containing
drivers for the most popular devices found on UltraSPARC hardware.<br>
For the latest list of drivers available on this image, take a look at the
<a href="https://cvsweb.openbsd.org/src/sys/arch/sparc64/conf/RAMDISK?rev=HEAD">RAMDISK</a>
kernel configuration file.
The CD can be booted off the OpenFirmware prompt with
<p>
<kbd>
boot cdrom
</kbd>
<li><strong>Floppy A</strong> (floppy73.img)
<p>
Booting off the floppy provides a small ffs filesystem with a kernel
containing supporting the following sparc64 hardware:
<ul>
<li>Ultra 1/1E
<li>Ultra 2
</ul>
<p>
as well as support for the on-board devices found on these machines.
However due to lack of space there are only a few other drivers.
In particular, this floppy <i>lacks cdrom support</i> and will <i>not</i>
allow installation from cdrom media.
For the latest list of drivers available on this image, take a look at the
<a href="https://cvsweb.openbsd.org/src/sys/arch/sparc64/conf/RAMDISKU1?rev=HEAD">RAMDISKU1</a>
kernel configuration file.
The floppy can be booted off the OpenFirmware prompt with
<p>
<kbd>
boot floppy
</kbd>
<p>
<li><strong>Floppy B</strong> (floppyB73.img)
<p>
Booting off the floppy provides a small ffs filesystem with a kernel
containing supporting the following sparc64 hardware:
<ul>
<li>SPARCengineUltra AX
<li>SPARCengineUltra AXe
<li>SPARCengineUltra AXi
</ul>
<p>
as well as support for the on-board devices found on these machines.
However due to lack of space there are only a few other drivers.
In particular, this floppy <i>lacks cdrom support</i> and will <i>not</i>
allow installation from cdrom media.
For the latest list of drivers available on this image, take a look at the
<a href="https://cvsweb.openbsd.org/src/sys/arch/sparc64/conf/RAMDISKU5?rev=HEAD">RAMDISKU5</a>
kernel configuration file.
The floppy can be booted off the OpenFirmware prompt with
<p>
<kbd>
boot floppy
</kbd>
<p>
<li><strong>Miniroot</strong> (miniroot73.img)
<p>
The miniroot provides the same installation environment as the CD ISO,
and is intended for easy bootstrap if there is already an operating system
installed on the machine.
After dumping the miniroot to the primary swap partition with dd, the
miniroot can be booted off the OpenFirmware prompt with a command such as
<p>
<kbd>
boot disk:b
</kbd>
<p>
(the disk designation may be different, depending on the chosen swap
partition).
<p>
<li><strong>Network boot</strong> (ofwboot.net, bsd.rd)
<p>
Using a diskless setup, it is also possible to boot the OpenBSD/sparc64
boot loader, <code>ofwboot.net</code>, from the network via tftp, and access
the <code>bsd.rd</code> standalone miniroot over NFS.
Refer to the
<a href="https://man.openbsd.org/diskless.8">diskless(8)</a>
manual page for details on how to setup a network boot environment.
</ul>
<p>
Please note that booting from floppy might not work on your machine; also,
Ultra 1, 1E and 2 systems might require a PROM update (they usually don't if
they are able to boot Solaris in 64bit-mode); please refer to the
installation notes for details.
