1.13 smurph 50:
51: <p>
1.16 smurph 52: The Motorola 88k processor is said to be the best RISC processor ever
1.17 deraadt 53: devised. Its simplicity and elegance combine to make the mvme88k a
1.16 smurph 54: hearty, robust platform.
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:
64: <p>
1.29 miod 65: Unfortunately, at the same time, a compiler upgrade from gcc 2.8.1 to
1.80 miod 66: egcs exposed a lot of problems in the mvme88k support in gcc, which
1.29 miod 67: could not be fixed in time for mvme88k to be a supported OpenBSD 2.5
68: release.
1.13 smurph 69:
70: <p>
1.29 miod 71: The lack of an in-tree toolchain did not prevent further work on the port,
72: and a lot of changes were made to the codebase, such as revamped autoconf
1.80 miod 73: and on-board SCSI driver, greatly expanded VME bus support, a working
74: install process that correctly creates a Motorola VID block on the disks,
1.29 miod 75: and support for MVME188 as well as improving support for MVME197.
1.13 smurph 76:
1.34 miod 77: <p>
78: During summer 2003, an effort to fix the toolchain eventually produced a
79: working gcc 2.95 compiler, and allowed the port to be self-hosting again.
1.54 miod 80: With the help of Mark Kettenis, the toolchain effort eventually produced
81: working binutils and gdb in late may 2004.
1.34 miod 82:
1.69 miod 83: <p>
84: Work towards multiprocessor support on the MVME188 boards started in
85: summer 2005 and, after a lot of tedious bugfixing, was eventually
86: completed shortly after the 4.2 release in november 2007.
87:
1.70 miod 88: <p>
89: The next step was getting the 88110-based MVME197 designs to work.
1.80 miod 90: Single-processor kernels started to run reliably in december 2007;
91: multiprocessor support was completed in march 2009, but kept triggering
92: obscure bugs which eventually got tracked down to a processor errata,
93: fixed for good in april 2010.

1.70 miod 100: Currently, MVME187, MVME188 and MVME197 boards, as well as similar
1.46 miod 101: designs, are booting multi-user, supporting most of the on-board devices.
1.39 david 102: There are still a few caveats; depending on your exact hardware setup,
103: your mileage may vary.
1.74 sthen 104: Work is in progress to fix the remaining problems.
