1.3 fn 60:
61: <p>
1.1 deraadt 62: The original BSD4.4 port was done by Chris Torek as a contract to
1.50 jason 63: LBL. The code was released by Chris in mid-1993, and Theo de Raadt
1.1 deraadt 64: worked it into shape for the NetBSD tree. Theo and Markus Wild worked
65: on improving Chris' original SunOS compatibility code into a highly
66: complete and reliable emulation. Chuck Cranor ported the sun4c code to
1.119 ! miod 67: the 8KB pagesize sun4 architecture, and Theo merged this code in a
1.1 deraadt 68: way that would allow the same kernel and programs to run on either
1.64 jason 69: sun4c or sun4 machines (unlike Sun's separate kernel environments).
1.1 deraadt 70: This last change also required a rewrite of the device configuration
1.25 johns 71: code. Just after the NetBSD/sparc 1.0 release, Peter Galbavy wrote an
72: ESP scsi device driver as a replacement for Chris' sparc-specific scsi
1.119 ! miod 73: code.
1.3 fn 74: </p>
1.1 deraadt 75:
76: <p>
77: At this point a conflict emerged between Theo and the other people he
78: started the NetBSD project with, and Theo was forced by the core group
79: to resign from NetBSD. After Theo left NetBSD, a few people in the
80: NetBSD group did some other things for the port: Paul Kranenburg
81: ported a floppy driver and started writing support for the 4/400.
82: Chuck spent many long hours working on the ie, xy, xd device drivers.
1.3 fn 83: </p>
1.1 deraadt 84:
85: <p>
86: Theo continued working independently, and made a number of additions:
1.119 ! miod 87: P4 support, flexible boot strategy, a few graphics drivers with the help
! 88: from John Stone, and masses of bug fixes.
1.3 fn 89: </p>
1.1 deraadt 90:
91: <p>
1.25 johns 92: Work on porting OpenBSD/sparc to the sun4m platform was started by Theo,
1.36 todd 93: but tendinitis problems with his wrists and the problems with the NetBSD
1.119 ! miod 94: core combined made him stop this work. The initial sun4m work was passed
1.7 deraadt 95: to Aaron Brown of Harvard, who was paid out of Margo Seltzer's research
1.119 ! miod 96: funds. This initial stuff consisted mostly of a few attempts at building
1.8 deraadt 97: pmap structure that could support all 3 MMU types efficiently. Also,
1.119 ! miod 98: David Miller of the UltraLinux project got a little bit involved.
1.7 deraadt 99: </p>
100:
101: <p>
1.27 downsj 102: Theo and Jason Downs merged the NetBSD sparc code back into OpenBSD, making
1.50 jason 103: OpenBSD/sparc usable again. Jason Wright wrote a few new SBus Ethernet
1.119 ! miod 104: drivers with information from the UltraLinux project and has merged a few bits
1.50 jason 105: from NetBSD sources to improve the stability of this architecture.
1.119 ! miod 106: Over the time, Art Grabowski fixed various stability or reliability issues,
! 107: and added non-executable stack and heap on sun4m machines.
! 108: The frame buffer and console code was completely overhauled for OpenBSD 3.2,
! 109: improving display speed with some frame buffers, and supporting more cards.
1.50 jason 110: </p>

1.6 downsj 133: </p>
134:
135: <p>
1.25 johns 136: An important note about OpenBSD/sparc is that it is designed so that
1.30 downsj 137: a single kernel can run on <b>ALL SUPPORTED</b> sparc machines. Whereas
1.92 jufi 138: SunOS and Solaris have always had separate `kernel architectures', i.e. sun4,
1.26 downsj 139: sun4c, and sun4m, the same `GENERIC' OpenBSD kernel will run on all the
140: supported models.
1.15 grr 141: </p>
142:
143: <p>
1.50 jason 144: Most of the problems with OpenBSD/sparc are believed to stem from the wide
145: variety of sparc processor and cache implementations along with their
146: undocumented bugs, rather then general kernel problems.
1.15 grr 147: Feedback on which models do and do not work reliably is
1.77 deraadt 148: appreciated, particularly with newer models or upgrades.
