1.13 smurph 49:
50: <p>
1.16 smurph 51: The Motorola 88k processor is said to be the best RISC processor ever
1.17 deraadt 52: devised. Its simplicity and elegance combine to make the mvme88k a
1.16 smurph 53: hearty, robust platform.
54: </p>
1.29 miod 55:
1.13 smurph 56: <p>
1.29 miod 57: Nivas Madhur started the initial mvme88k port for the MVME187 card, but
58: has since moved on to another employer.
59: The port was brought in the OpenBSD tree by Dale Rahn, but he did not
60: have enough time to work on it.
61: Steve Murphree, Jr. eventually completed the port to the MVME187 in
62: November 1998.
1.13 smurph 63: </p>
64:
65: <p>
1.29 miod 66: Unfortunately, at the same time, a compiler upgrade from gcc 2.8.1 to
67: egcs revealed a lot of problems in the mvme88k support in gcc, which
68: could not be fixed in time for mvme88k to be a supported OpenBSD 2.5
69: release.
1.13 smurph 70: </p>
71:
72: <p>
1.29 miod 73: The lack of an in-tree toolchain did not prevent further work on the port,
74: and a lot of changes were made to the codebase, such as revamped autoconf
75: and on-board SCSI driver, greatly expanded VME bus support, working install
76: process that correctly creates a Motorola VID block on the disks,
77: and support for MVME188 as well as improving support for MVME197.
1.13 smurph 78: </p>
79:
1.34 miod 80: <p>
81: During summer 2003, an effort to fix the toolchain eventually produced a
82: working gcc 2.95 compiler, and allowed the port to be self-hosting again.
