56: <p>
1.16 smurph 57: The Motorola 88k processor is said to be the best RISC processor ever
1.17 deraadt 58: devised. Its simplicity and elegance combine to make the mvme88k a
1.16 smurph 59: hearty, robust platform.
1.29 miod 60:
1.13 smurph 61: <p>
1.29 miod 62: Nivas Madhur started the initial mvme88k port for the MVME187 card, but
63: has since moved on to another employer.
64: The port was brought in the OpenBSD tree by Dale Rahn, but he did not
65: have enough time to work on it.
66: Steve Murphree, Jr. eventually completed the port to the MVME187 in
67: November 1998.
1.13 smurph 68:
69: <p>
1.29 miod 70: Unfortunately, at the same time, a compiler upgrade from gcc 2.8.1 to
71: egcs revealed a lot of problems in the mvme88k support in gcc, which
72: could not be fixed in time for mvme88k to be a supported OpenBSD 2.5
73: release.
1.13 smurph 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.
1.13 smurph 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.
1.54 miod 85: With the help of Mark Kettenis, the toolchain effort eventually produced
86: working binutils and gdb in late may 2004.
1.34 miod 87:
1.69 miod 88: <p>
89: Work towards multiprocessor support on the MVME188 boards started in
90: summer 2005 and, after a lot of tedious bugfixing, was eventually
91: completed shortly after the 4.2 release in november 2007.
92:
1.70 miod 93: <p>
94: The next step was getting the 88110-based MVME197 designs to work.
95: Single-processor kernels started to run reliably in december 2007.

1.46 miod 103: designs, are booting multi-user, supporting most of the on-board devices.
1.39 david 104: There are still a few caveats; depending on your exact hardware setup,
105: your mileage may vary.
1.74 sthen 106: Work is in progress to fix the remaining problems.
