1.3 fn 44:
45: <p>
1.1 deraadt 46: The original BSD4.4 port was done by Chris Torek as a contract to
1.50 jason 47: LBL. The code was released by Chris in mid-1993, and Theo de Raadt
1.1 deraadt 48: worked it into shape for the NetBSD tree. Theo and Markus Wild worked
49: on improving Chris' original SunOS compatibility code into a highly
50: complete and reliable emulation. Chuck Cranor ported the sun4c code to
51: the 8KB pagesized Sun4 architecture, and Theo merged this code in a
52: way that would allow the same kernel and programs to run on either
1.64 jason 53: sun4c or sun4 machines (unlike Sun's separate kernel environments).
1.1 deraadt 54: This last change also required a rewrite of the device configuration
1.25 johns 55: code. Just after the NetBSD/sparc 1.0 release, Peter Galbavy wrote an
56: ESP scsi device driver as a replacement for Chris' sparc-specific scsi
1.50 jason 57: code, this new driver unfortunately had some problems and was eventually
58: replaced.
1.3 fn 59: </p>
1.1 deraadt 60:
61: <p>
62: At this point a conflict emerged between Theo and the other people he
63: started the NetBSD project with, and Theo was forced by the core group
64: to resign from NetBSD. After Theo left NetBSD, a few people in the
65: NetBSD group did some other things for the port: Paul Kranenburg
66: ported a floppy driver and started writing support for the 4/400.
67: Chuck spent many long hours working on the ie, xy, xd device drivers.
1.3 fn 68: </p>
1.1 deraadt 69:
70: <p>
71: Theo continued working independently, and made a number of additions:
72: P4 support, flexible boot strategy, a few graphics drivers with help
73: from John Stone, and masses of bug fixes. Many people will be most
74: interested that the ESP scsi driver has been completely replaced by
75: Theo, and that it supports disconnect/reconnect.
1.3 fn 76: </p>
1.1 deraadt 77:
78: <p>
1.25 johns 79: Work on porting OpenBSD/sparc to the sun4m platform was started by Theo,
1.36 todd 80: but tendinitis problems with his wrists and the problems with the NetBSD
1.7 deraadt 81: core conspired, and he stopped work. Theo passed his initial sun4m work
82: to Aaron Brown of Harvard, who was paid out of Margo Seltzer's research
83: funds. This initial stuff consisted mostly of a few attempts at building
1.8 deraadt 84: pmap structure that could support all 3 MMU types efficiently. Also,
1.50 jason 85: David Miller of the S/Linux project got a little bit involved.
1.7 deraadt 86: </p>
87:
88: <p>
1.27 downsj 89: Theo and Jason Downs merged the NetBSD sparc code back into OpenBSD, making
1.50 jason 90: OpenBSD/sparc usable again. Jason Wright wrote a few new SBus Ethernet
91: drivers with information from the S/Linux project and has merged a few bits
92: from NetBSD sources to improve the stability of this architecture.
93: </p>
94:
95: <p>
96: And work continues...

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