1.3 fn 43:
44: <p>
1.1 deraadt 45: The original BSD4.4 port was done by Chris Torek as a contract to
1.50 jason 46: LBL. The code was released by Chris in mid-1993, and Theo de Raadt
1.1 deraadt 47: worked it into shape for the NetBSD tree. Theo and Markus Wild worked
48: on improving Chris' original SunOS compatibility code into a highly
49: complete and reliable emulation. Chuck Cranor ported the sun4c code to
50: the 8KB pagesized Sun4 architecture, and Theo merged this code in a
51: way that would allow the same kernel and programs to run on either
1.64 jason 52: sun4c or sun4 machines (unlike Sun's separate kernel environments).
1.1 deraadt 53: This last change also required a rewrite of the device configuration
1.25 johns 54: code. Just after the NetBSD/sparc 1.0 release, Peter Galbavy wrote an
55: ESP scsi device driver as a replacement for Chris' sparc-specific scsi
1.50 jason 56: code, this new driver unfortunately had some problems and was eventually
57: replaced.
1.3 fn 58: </p>
1.1 deraadt 59:
60: <p>
61: At this point a conflict emerged between Theo and the other people he
62: started the NetBSD project with, and Theo was forced by the core group
63: to resign from NetBSD. After Theo left NetBSD, a few people in the
64: NetBSD group did some other things for the port: Paul Kranenburg
65: ported a floppy driver and started writing support for the 4/400.
66: Chuck spent many long hours working on the ie, xy, xd device drivers.
1.3 fn 67: </p>
1.1 deraadt 68:
69: <p>
70: Theo continued working independently, and made a number of additions:
71: P4 support, flexible boot strategy, a few graphics drivers with help
72: from John Stone, and masses of bug fixes. Many people will be most
73: interested that the ESP scsi driver has been completely replaced by
74: Theo, and that it supports disconnect/reconnect.
1.3 fn 75: </p>
1.1 deraadt 76:
77: <p>
1.25 johns 78: Work on porting OpenBSD/sparc to the sun4m platform was started by Theo,
1.36 todd 79: but tendinitis problems with his wrists and the problems with the NetBSD
1.7 deraadt 80: core conspired, and he stopped work. Theo passed his initial sun4m work
81: to Aaron Brown of Harvard, who was paid out of Margo Seltzer's research
82: funds. This initial stuff consisted mostly of a few attempts at building
1.8 deraadt 83: pmap structure that could support all 3 MMU types efficiently. Also,
1.50 jason 84: David Miller of the S/Linux project got a little bit involved.
1.7 deraadt 85: </p>
86:
87: <p>
1.27 downsj 88: Theo and Jason Downs merged the NetBSD sparc code back into OpenBSD, making
1.50 jason 89: OpenBSD/sparc usable again. Jason Wright wrote a few new SBus Ethernet
90: drivers with information from the S/Linux project and has merged a few bits
91: from NetBSD sources to improve the stability of this architecture.

1.6 downsj 113: </p>
114:
115: <p>
1.25 johns 116: An important note about OpenBSD/sparc is that it is designed so that
1.30 downsj 117: a single kernel can run on <b>ALL SUPPORTED</b> sparc machines. Whereas
1.92 jufi 118: SunOS and Solaris have always had separate `kernel architectures', i.e. sun4,
1.26 downsj 119: sun4c, and sun4m, the same `GENERIC' OpenBSD kernel will run on all the
120: supported models.
1.15 grr 121: </p>
122:
123: <p>
1.50 jason 124: Most of the problems with OpenBSD/sparc are believed to stem from the wide
125: variety of sparc processor and cache implementations along with their
126: undocumented bugs, rather then general kernel problems.
1.15 grr 127: Feedback on which models do and do not work reliably is
1.77 deraadt 128: appreciated, particularly with newer models or upgrades.
1.15 grr 129: </p>
130:
131: <p>
1.73 deraadt 132: OpenBSD/sparc can be installed or upgraded via floppy boot images on
133: sun4c and sun4m, miniroot images for machines without floppies
134: (and sun4 machines), as well as network and diskless installs.
