Sgi Octane and T2/Linux

Sgi Octane

The Octane, known also as IP30, is a series of high-end graphics workstation that was manufactured by Sgi from 1997 until 2004.

The distinct green (or blue, in case of Octane2), squat, somewhat blobby shape of the Octane is instantly recognizable as a Silicon Graphics machine.

The Octane can be equiped with 64-bit MIPS CPUs running from 175 MHz up to 600 MHz in single and dual CPU configurations.

Although the support for Octane is not (yet) in the vanilla Linux kernel, T2 comes with a specially patched linux26-mips package providing the support.

The Sgi Octane is used for general MIPS and MIPS64 development.

The graphic board can either be an Sgi Impact, or Sgi VPro - code namsed ODYSSEY. While for both boards a Linux frame buffer driver exists, a basic X.org driver is only available for the Sgi Impact. Although there is not yet an X.org driver for the Sgi VPro, it's a rather nice graphic hardware that interprets a real OpenGL command stream in hardware.
