OpenBSD/mvme68k

History and Status:

This port was primarily done by Theo de Raadt in 1995 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. For most kernel parts, both their ports were analysed but more code was written new by Theo, or 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. Steve Murphee continued work and made the MVME177 work, as well as adding support for some VME devices.

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

The same kernel currently runs on the following pieces of hardware:

• MVME147: 68030
  This works stably.
  • Everything supported except the parallel port.
  • I have a driver for the parallel port, but it is not integrated yet.

• MVME162: 68040
  This works stably.
  • Everything important working.. with these additional notes:
  • SCSI working (4.5MB/sec off a 4.2G Quantum Grand Prix).
    
  • VME bus support untested
  • parity and ecc not supported
  • flash driver not working
  • IP module driver untested

• MVME165: 68040
  What little we know about it makes us think it is doable.

• MVME166: 68040
  This might already work. Anyone want to test it?

• MVME167C: 68040
  This works stably.
  • Works as well as the MVME162 port above, plus these notes:
  • parallel port not supported.

• MVME177-001: 68060
  This works stably.
  • Works as well as the MVME167 port.

• MVME376: VME Lance ethernet
• MVME328: SCSI controller

For all these architectures, both diskless booting using sun-style bootparams/nfs and regular full disk booting are supported.

Note: This port has COMPAT_SUNOS support, so it can run SunOS sun3 binaries. As such, I think that the MVME177 is probably the fastest machine capable of running SunOS sun3 binaries....

Snapshots are made available from time to time.

What does it look like? This is a MVME162. Following it is the boot log from a MVME177.
