52: <p>
1.16 smurph 53: The Motorola 88k processor is said to be the best RISC processor ever
1.17 deraadt 54: devised. Its simplicity and elegance combine to make the mvme88k a
1.16 smurph 55: hearty, robust platform.
56: </p>
1.29 ! miod 57:
1.13 smurph 58: <p>
1.29 ! miod 59: Nivas Madhur started the initial mvme88k port for the MVME187 card, but
! 60: has since moved on to another employer.
! 61: The port was brought in the OpenBSD tree by Dale Rahn, but he did not
! 62: have enough time to work on it.
! 63: Steve Murphree, Jr. eventually completed the port to the MVME187 in
! 64: November 1998.
1.13 smurph 65: </p>
66:
67: <p>
1.29 ! miod 68: Unfortunately, at the same time, a compiler upgrade from gcc 2.8.1 to
! 69: egcs revealed a lot of problems in the mvme88k support in gcc, which
! 70: could not be fixed in time for mvme88k to be a supported OpenBSD 2.5
! 71: release.
! 72: As of today, these problems are still not entirely fixed.
1.13 smurph 73: </p>
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.

! 120: devices; it just acts as a container for an <i>HyperModule</i> which provides
! 121: 1, 2 or 4 processors, and associated Cache/Memory Management Units
! 122: (<i>CMMU</i>).
! 123: All existing HyperModule models should be supported, but this has only been
! 124: tested so far on 1P64 (1 cpu, 4 cmmu) and 2P256 (2 cpu, 4 cmmu) modules.
! 125: External cards specific to the MVME188 family provide memory and serial ports.
! 126: <li><strong>MVME197</strong> (single or dual processor 88110)<br>
! 127: The MVME197 boards come in different flavours, differing by the number of
1.26 miod 128: processors (1 or 2) and the optional presence of an external cache controller.
129: All existing configurations should be supported, but this has only been tested
1.29 ! miod 130: on a MVME197LE (no external cache controller) board.
! 131: Support for this board is still very experimental and has issues.
