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
1.89 miod 54: hearty, robust platform.
1.29 miod 55:
1.13 smurph 56: <p>
1.89 miod 57: Unfortunately, the first generation designs (88100) made use of companion chips
58: for cache and virtual memory management, making hardware designs painfully
59: complex (and expensive, at that time). The second generation (88110) addressed
1.91 miod 60: this issue, but was plagued with reliability issues. Eventually, Motorola
1.89 miod 61: seized the opportunity to drop the 88000 line in favour of the PowerPC as soon
62: as possible, although some parts of the 88110 still exist in the PowerPC family
63: processors today.
64:
65: <p>
66: Nivas Madhur started the initial mvme88k port for the MVME187 card, building
67: upon the CMU Mach code running on the 88100-based Omron Luna88k systems.
68: However, he moved on to another employer before his work was ready to be
69: imported into the OpenBSD source tree.
70:
71: <p>
72: This integration work was completed by Dale Rahn, but he did not have enough
73: time to continue working on the port. Steve Murphree, Jr., stepped up, and
74: eventually completed the port to the MVME187 in November 1998.
1.13 smurph 75:
76: <p>
1.29 miod 77: Unfortunately, at the same time, a compiler upgrade from gcc 2.8.1 to
1.80 miod 78: egcs exposed a lot of problems in the mvme88k support in gcc, which
1.29 miod 79: could not be fixed in time for mvme88k to be a supported OpenBSD 2.5
80: release.
1.13 smurph 81:
82: <p>
1.29 miod 83: The lack of an in-tree toolchain did not prevent further work on the port,
84: and a lot of changes were made to the codebase, such as revamped autoconf
1.80 miod 85: and on-board SCSI driver, greatly expanded VME bus support, a working
86: install process that correctly creates a Motorola VID block on the disks,
1.29 miod 87: and support for MVME188 as well as improving support for MVME197.
1.13 smurph 88:
1.34 miod 89: <p>
90: During summer 2003, an effort to fix the toolchain eventually produced a
91: working gcc 2.95 compiler, and allowed the port to be self-hosting again.
1.54 miod 92: With the help of Mark Kettenis, the toolchain effort eventually produced
93: working binutils and gdb in late may 2004.
1.34 miod 94:
1.69 miod 95: <p>
96: Work towards multiprocessor support on the MVME188 boards started in
97: summer 2005 and, after a lot of tedious bugfixing, was eventually
98: completed shortly after the 4.2 release in november 2007.
99:
1.70 miod 100: <p>
101: The next step was getting the 88110-based MVME197 designs to work.
1.80 miod 102: Single-processor kernels started to run reliably in december 2007;
103: multiprocessor support was completed in march 2009, but kept triggering
104: obscure bugs which eventually got tracked down to a processor errata,
105: fixed for good in april 2010.
1.70 miod 106:
1.89 miod 107: <p>
108: The long-awaited switch from the a.out binary format to ELF happened after the
109: 5.2 release, with a compiler upgrade to gcc 3.3.6. This work paved the way
1.90 miod 110: for ELF shared libraries support.
