This page contains information about the FreeBSD port to Sun Microsystem's UltraSPARC® architecture. Discussion of the UltraSPARC port takes place on the freebsd-sparc mailing list.
UltraSPARC is a Tier 2 architecture, and as such is not fully supported by the FreeBSD project. Although fully functional, the port is not as mature as the existing i386 or amd64 ports.
A summary of supported systems follows. SMP is supported on all supported systems that contain more than 1 processor. For full details please see the release notes of the release you are using.
The following systems are partially supported by FreeBSD. In particular the fibre channel controllers in SBus-based systems are not supported. However, it is possible to use these with a SCSI controller supported by the esp(4) driver (Sun ESP SCSI, Sun FAS Fast-SCSI and Sun FAS366 Fast-Wide SCSI controllers).
Starting with 7.2-RELEASE, sparc64 systems based on UltraSPARC III and beyond are also supported by FreeBSD, which includes the following known working systems:
The following UltraSPARC IIIi systems are not tested but believed to be also supported by FreeBSD:
If you have a system that is not listed here please try it, and let us know about it.
Note that newer UltraSPARC-T1® processor based systems are supported by the FreeBSD/sun4v Project
The following people have been working either in the spotlights or behind the scenes to get the FreeBSD port off the ground:
