OpenBSD/sparc64

OpenBSD/sparc64 runs on the 64bit Sun UltraSPARC machines based on the UltraSPARC I, II, and III processors.

A mailing list dedicated to the OpenBSD/sparc and OpenBSD/sparc64 ports is available at sparc@openbsd.org. To join the OpenBSD/sparc and OpenBSD/sparc64 mailing list, send a message body of "subscribe sparc" to majordomo@openbsd.org. Please be sure to check our mailing list policy before subscribing.

The current port maintainer is Jason Wright (jason@openbsd.org), with the help of mainly Art Grabowski. Others are definitely welcome to contribute!

History:

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.

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) and bugs exposed by the 64 bit big endian nature of UltraSPARC in many obscure places have been fixed.

Sun refused access to the neccessary documentaion for the (very bizzare) host bridge in the UltraSPARC III machines, so a few years were lost before some reverse engineering figured out the changes in these machines. OpenBSD 4.0 is thus the first release to ship with support for the UltraSPARC III based machines.

And since there are always little bits missing, work is continuing...

Current status:

Currently most of the hardware available to the developers boots multiuser and supports enough of the on-board devices to be generally usable.

The X Window System is supported on most systems. Only the ATI graphics adapters are supported with the accelerated X.Org server at the current time. It is possible to use X in frame buffer mode with all supported SBus cards, as well as the on-board ATI graphics or the UPA Creator, Creator 3D or Elite 3D at the boot resolution/depth using the wsfb(4) driver.

The directions on how to enable the accelerated and unaccelerated X server are present in the /usr/X11R6/README file on the installed system.

Getting and installing OpenBSD/sparc64:

The latest supported OpenBSD/sparc64 release is OpenBSD 3.9. Here are the OpenBSD/sparc64 3.9 installation instructions .

Snapshots are made available from time to time, in this location as well as in a few mirrors. Here are the OpenBSD/sparc64 snapshot installation instructions as well.

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.

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.
