OpenBSD/sparc runs on most of the 32bit Sun SPARC workstations, including

the sun4, sun4c, sun4e and sun4m architecture families

(but not the 64bit UltraSPARC computers, which are supported by

<p>

The original 4.4BSD port was done by Chris Torek as a contract to

Line 57

code. Just after the NetBSD/sparc 1.0 release, Peter Galbavy wrote an

ESP SCSI device driver as a replacement for Chris' sparc-specific SCSI

code.

</p>

<p>

At this point a conflict emerged between Theo and the other people he

Line 65

NetBSD group did some other things for the port: Paul Kranenburg

ported a floppy driver and started writing support for the 4/400.

Chuck spent many long hours working on the ie, xy, xd device drivers.

</p>

<p>

Theo continued working independently, and made a number of additions:

P4 support, flexible boot strategy, a few graphics drivers with the help

from John Stone, and masses of bug fixes.

</p>

<p>

Work on porting OpenBSD/sparc to the sun4m platform was started by Theo,

Line 79

funds. This initial stuff consisted mostly of a few attempts at building

pmap structure that could support all 3 MMU types efficiently. Also,

David Miller of the UltraLinux project got a little bit involved.

</p>

<p>

Theo and Jason Downs merged the NetBSD sparc code back into OpenBSD, making

Line 90

Line 89

and added non-executable stack and heap on sun4m machines.

The frame buffer and console code was completely overhauled for OpenBSD 3.2,

improving display speed with some frame buffers, and supporting more cards.

<p>

Currently, all the hardware listed in the

Line 102

Line 100

multi-user, and supports enough (if not all) of the on-board devices to

be generally usable.

A growing set of third-party SBus cards are also supported.

</p>

<p>

The X Window System works on all supported frame buffers, including

multi-head configurations.

No accelerated server is provided at the moment, although this is being

worked on.

</p>

<p>

An important note about OpenBSD/sparc is that it is designed so that

a single kernel can run on <b>ALL SUPPORTED</b> SPARC machines. Whereas

a single kernel can run on <strong>ALL SUPPORTED</strong> SPARC machines. Whereas

SunOS and Solaris have always had separate `kernel architectures', i.e. sun4,

SunOS and Solaris have always had separate 'kernel architectures', i.e. sun4,

sun4c, sun4e and sun4m, the same `GENERIC' OpenBSD kernel will run on all the

sun4c, sun4e and sun4m, the same 'GENERIC' OpenBSD kernel will run on all the

supported models.

</p>

<p>

Most of the problems with OpenBSD/sparc are believed to stem from the wide

Line 125

Line 120

undocumented bugs, rather than general kernel problems.

Feedback on which models do and do not work reliably is

appreciated, particularly with newer models or upgrades.
