1.45 miod 23: OpenBSD/mvme88k is an effort to port OpenBSD to the systems built upon
24: Motorola's 881x0-based VME motherboard family.

1.13 smurph 46:
47: <p>
1.16 smurph 48: The Motorola 88k processor is said to be the best RISC processor ever
1.17 deraadt 49: devised. Its simplicity and elegance combine to make the mvme88k a
1.16 smurph 50: hearty, robust platform.
1.29 miod 51:
1.13 smurph 52: <p>
1.29 miod 53: Nivas Madhur started the initial mvme88k port for the MVME187 card, but
54: has since moved on to another employer.
55: The port was brought in the OpenBSD tree by Dale Rahn, but he did not
56: have enough time to work on it.
57: Steve Murphree, Jr. eventually completed the port to the MVME187 in
58: November 1998.
1.13 smurph 59:
60: <p>
1.29 miod 61: Unfortunately, at the same time, a compiler upgrade from gcc 2.8.1 to
62: egcs revealed a lot of problems in the mvme88k support in gcc, which
63: could not be fixed in time for mvme88k to be a supported OpenBSD 2.5
64: release.
1.13 smurph 65:
66: <p>
1.29 miod 67: The lack of an in-tree toolchain did not prevent further work on the port,
68: and a lot of changes were made to the codebase, such as revamped autoconf
69: and on-board SCSI driver, greatly expanded VME bus support, working install
70: process that correctly creates a Motorola VID block on the disks,
71: and support for MVME188 as well as improving support for MVME197.
1.13 smurph 72:
1.34 miod 73: <p>
74: During summer 2003, an effort to fix the toolchain eventually produced a
75: working gcc 2.95 compiler, and allowed the port to be self-hosting again.
1.54 miod 76: With the help of Mark Kettenis, the toolchain effort eventually produced
77: working binutils and gdb in late may 2004.

1.13 smurph 83: <p>
1.55 miod 84: Currently, only the MVME187 and MVME188 boards, as well as similar
1.46 miod 85: designs, are booting multi-user, supporting most of the on-board devices.
1.39 david 86: There are still a few caveats; depending on your exact hardware setup,
87: your mileage may vary.
1.37 miod 88: Work is on progress to fix the remaining problems and reliably support more
89: boards.
