OpenBSD/mvme68k

OpenBSD/mvme68k

History and Status:

This port was primarily done by Theo de Raadt as a contract to Willowglen Singapore. An earlier port to the MVME147 by Chuck Cranor based on Paul Mackerras' old DA30 code (and using hardware donated by Jonathan Levine at Theo's request) provided a solid development platform. Bizzarely, Dale Rahn of Motorola also independently wrote a port to the MVME147. Both their ports have since been superceded by new code written by Theo based on the hp300 code. Dale helped significantly during the porting to the 68040 models and wrote most of the code specific to the MVME167 model.

The people working the most on OpenBSD/mvme68k currently consists of Theo de Raadt, and Dale Rahn. Of course others are very welcome!

The cards look a little like this. (a picture of a real MVME16x card would be nice, please mail deraadt@openbsd.org if you find one.)

The same kernel will (hopefully) eventually run on all of the following:

MVME147 (68030): this works stably

  • parallel port not supported.
    MVME162 (68040): this works stably
  • SCSI working (4.5MB/sec off a 4.2G Quantum Grand Prix).
  • VME possibly not working
  • parity and ecc not supported.
  • flash driver not working
  • IP module driver untested
    MVME165 (68040): what little I know about it makes me think it doable.
    MVME166 (68040): this might already work. anyone want to test it?
    MVME167 (68040): this works stably
  • SCSI working (4.5MB/sec off a 4.2G Quantum Grand Prix).
  • VME possibly not working
  • parity and ecc not supported.
  • parallel port not supported.
    MVME177 (68060): Dale appears to be slowly working on this.

    Motorola makes a few older 68020/68851 models which could perhaps also be supported. As well, I've noticed that Heurikon 68040/68060 cards have similar scsi/ethernet/serial/vme chips.

    For all these ports, diskless booting using sun-style bootparams/nfs works fine.

    Note: This port has COMPAT_SUNOS support, so it can run SunOS sun3 binaries. As such, I think this is probably the fastest machine capable of running SunOS sun3 binaries....

    Where to get it?

    The third binary snapshot (built on Nov 22) is now available.

    You should also read the general description about OpenBSD snapshots.

    What does it look like?
