gentoo/octane – A modern GNU/Linux system for the SGI Octane Workstation

It took about 6 months of work, and it's done: gentoo/octane 1.0 has been released.

Grab your copy here: gentoo-octane-v1.0-by-rephlex.tar.xz

It's basically a complete tarball of the system. So:

  • attach scsi disk to any machine or netboot the octane using root=/dev/nfs nfsroot=a.b.c.d/path/to/filesystem (if you're a tough guy)
  • prepare the octanes local disks
  • add tarball
  • set envvars (included)
  • profit

What works:

  • everything that would work in any random gentoo that is up-to-date as of April 2019 😉
  • Kernel 4.12 with audio, and all the funny devices inside the octane including impact graphics.

What doesn't work yet:

  • xf86-video-impact xorg module ;/ – see /etc/motd for how to achieve running xorg. It's ALMOST DONE!
  • Kernel newer than 4.12. The patches need to be tested and maybe adjusted, that's it.

IF YOU HAVE THOSE PATCHES, PLEASE CONTACT ME!

Gentoo GNU/Linux on an SGI Octane

UPDATE: gentoo/octane is released. CLICK HERE!

Finally!

More info will be coming soon. Just come teaser to get you interested 😉

I AM running Linux 4.12 in full 64 bits, gcc 8, a current glibc, and all the modern software. WITH audio. WITH accellerated graphics. And my root volume is on 3x147GB SCSI Software RAID-0 stripeset goodness. And yes, I do have multiple backups. Boom!
