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.
1.13 smurph 72: </p>
73:
74: <p>
1.29 miod 75: The lack of an in-tree toolchain did not prevent further work on the port,
76: and a lot of changes were made to the codebase, such as revamped autoconf
77: and on-board SCSI driver, greatly expanded VME bus support, working install
78: process that correctly creates a Motorola VID block on the disks,
79: and support for MVME188 as well as improving support for MVME197.
1.13 smurph 80: </p>
81:
1.34 miod 82: <p>
83: During summer 2003, an effort to fix the toolchain eventually produced a
84: working gcc 2.95 compiler, and allowed the port to be self-hosting again.

1.13 smurph 91: <p>
1.33 miod 92: Recent work on the toolchain eventually produced a working compiler, although
93: optimization is not yet totally reliable. Unfortunately, a few kernel bugs
94: prevent the system from being very stable at the moment.
