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

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

123: <li><strong>MVME188</strong> (one to four 88100 processors)<br>
124: Contrary to the other MVME processor boards, this board has no on-board
125: devices; it just acts as a container for an <i>HyperModule</i> which provides
126: 1, 2 or 4 processors, and associated Cache/Memory Management Units
127: (<i>CMMU</i>).
128: All existing HyperModule models should be supported, but this has only been
129: tested so far on 1P64 (1 cpu, 4 cmmu) and 2P256 (2 cpu, 4 cmmu) modules.
130: External cards specific to the MVME188 family provide memory and serial ports.
131: <li><strong>MVME197</strong> (single or dual processor 88110)<br>
132: The MVME197 boards come in different flavours, differing by the number of
1.26 miod 133: processors (1 or 2) and the optional presence of an external cache controller.
134: All existing configurations should be supported, but this has only been tested
1.29 miod 135: on a MVME197LE (no external cache controller) board.
136: Support for this board is still very experimental and has issues.
