OpenBSD/sgi

OpenBSD sgi

OpenBSD/sgi runs on most 64 bit MIPS-based SGI servers and workstations. OpenBSD/sgi is a fully featured 64 bit port and will thus only run on systems based on 64 bit processors, i.e. R4000 and up.

The OpenBSD/sgi port was discontinued after the 6.9 release.

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

History

The OpenBSD/sgi port has its roots in the OpenBSD/arc port created early in the OpenBSD history. ARC support was rather soon discontinued due to the lack of interest and availability of decent hardware.

Eventually SGI hardware became more affordable and obtainable, and interest for an SGI port in the tree increased. The final piece, a working 64 bit toolchain, eventually became available and allowed the 64 bit SGI OpenBSD port to appear in 2004.

Hardware support was initially limited to the O2 workstations. Efforts to port to more systems did not really start until 2008, where the first Octane support parts were introduced. This work was completed in 2009 with support for Origin family systems as well, allowing OpenBSD to be the first free operating system to run on the Fuel workstations, and even later, also on Origin 350 servers.

The earlier generation of R4000 Indigo, Indy and Indigo2 was not forgotten either and support for it appeared in 2012. This paved the way for R8000 and R10000 POWER Indigo2 support as well.

Current status

OpenBSD/sgi runs in 64 bit mode and boots multi-user on supported systems. All graphics options but the IP27 Kona frame buffer should be supported. On such setups, the kernel will be limited to serial console operation only. An X server, currently unaccelerated, is also available for IP32 (O2) systems.

Supported hardware

For a complete system component and device driver listing for this architecture, see intro(4/sgi).

The following families are supported:

IP20 (R4000 Indigo) family:
- Indigo (R4000 and R4400 models)

IP22 (Indy, Indigo2) family:
- Challenge S
- Indy
- Indigo2
All R4000, R4400, R4600 and R5000 processor options are supported.

IP26 (POWER Indigo2) family:
- POWER Indigo2 R8000

IP27 (Origin) family:
- Origin 200
Origin 2000 and Onyx 2 are not supported yet. Single-node multiprocessor operation is supported on Origin 200.

IP28 (POWER Indigo2) family:
- POWER Indigo2 R10000

IP30 (Octane a.k.a Speedracer) family:
- Octane
- Octane 2
Multiprocessor operation is supported.

IP32 (O2 a.k.a Moosehead) family:
- O2
- O2+
R5000, RM5200, RM7000 as well as R10000 and R12000 processor options are supported, including the RM7000 level 3 cache.

IP35 (Tezro) family:
- Fuel
- Origin 3000
- Origin 350
- Tezro
- Onyx 4 (currently limited to serial console)
- Onyx 350 has not been tested, but ought to work since it is very similar to Origin 350.
Origin 300 and Onyx 300 are not supported yet. Single-node multiprocessor operation is supported at least on Origin 350.

Note that Octane 3 and Origin 400 systems are completely different architectures based on x86 processors, and as such are not supported by OpenBSD/sgi.
