1.16      smurph     55: The Motorola 88k processor is said to be the best RISC processor ever
1.17      deraadt    56: devised.  Its simplicity and elegance combine to make the mvme88k a
1.89      miod       57: hearty, robust platform.
1.29      miod       58:
1.13      smurph     59: <p>
1.89      miod       60: Unfortunately, the first generation designs (88100) made use of companion chips
                     61: for cache and virtual memory management, making hardware designs painfully
                     62: complex (and expensive, at that time).  The second generation (88110) addressed
1.91      miod       63: this issue, but was plagued with reliability issues.  Eventually, Motorola
1.89      miod       64: seized the opportunity to drop the 88000 line in favour of the PowerPC as soon
                     65: as possible, although some parts of the 88110 still exist in the PowerPC family
                     66: processors today.
                     67:
                     68: <p>
                     69: Nivas Madhur started the initial mvme88k port for the MVME187 card, building
                     70: upon the CMU Mach code running on the 88100-based Omron Luna88k systems.
                     71: However, he moved on to another employer before his work was ready to be
                     72: imported into the OpenBSD source tree.
                     73:
                     74: <p>
                     75: This integration work was completed by Dale Rahn, but he did not have enough
                     76: time to continue working on the port.  Steve Murphree, Jr., stepped up, and
                     77: eventually completed the port to the MVME187 in November 1998.

                     79: <p>
1.29      miod       80: Unfortunately, at the same time, a compiler upgrade from gcc 2.8.1 to
1.80      miod       81: egcs exposed a lot of problems in the mvme88k support in gcc, which
1.29      miod       82: could not be fixed in time for mvme88k to be a supported OpenBSD 2.5
                     83: release.

                     85: <p>
1.29      miod       86: The lack of an in-tree toolchain did not prevent further work on the port,
                     87: and a lot of changes were made to the codebase, such as revamped autoconf
1.80      miod       88: and on-board SCSI driver, greatly expanded VME bus support, a working

1.34      miod       92: <p>
                     93: During summer 2003, an effort to fix the toolchain eventually produced a
                     94: working gcc 2.95 compiler, and allowed the port to be self-hosting again.
1.54      miod       95: With the help of Mark Kettenis, the toolchain effort eventually produced
                     96: working binutils and gdb in late may 2004.

1.69      miod       98: <p>
                     99: Work towards multiprocessor support on the MVME188 boards started in
                    100: summer 2005 and, after a lot of tedious bugfixing, was eventually
                    101: completed shortly after the 4.2 release in november 2007.

1.80      miod      105: Single-processor kernels started to run reliably in december 2007;
                    106: multiprocessor support was completed in march 2009, but kept triggering
                    107: obscure bugs which eventually got tracked down to a processor errata,
                    108: fixed for good in april 2010.

                    111: The long-awaited switch from the a.out binary format to ELF happened after the
1.93      sthen     112: 5.3 release, with a compiler upgrade to gcc 3.3.6.  This work paved the way
