1.3 fn 46:
47: <p>
1.126 jufi 48: The original 4.4BSD port was done by Chris Torek as a contract to
1.50 jason 49: LBL. The code was released by Chris in mid-1993, and Theo de Raadt
1.1 deraadt 50: worked it into shape for the NetBSD tree. Theo and Markus Wild worked
51: on improving Chris' original SunOS compatibility code into a highly
52: complete and reliable emulation. Chuck Cranor ported the sun4c code to
1.119 miod 53: the 8KB pagesize sun4 architecture, and Theo merged this code in a
1.1 deraadt 54: way that would allow the same kernel and programs to run on either
1.64 jason 55: sun4c or sun4 machines (unlike Sun's separate kernel environments).
1.1 deraadt 56: This last change also required a rewrite of the device configuration
1.25 johns 57: code. Just after the NetBSD/sparc 1.0 release, Peter Galbavy wrote an
1.154 nick 58: ESP SCSI device driver as a replacement for Chris' sparc-specific SCSI
1.119 miod 59: code.
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.
68:
69: <p>
70: Theo continued working independently, and made a number of additions:
1.119 miod 71: P4 support, flexible boot strategy, a few graphics drivers with the help
72: from John Stone, and masses of bug fixes.
1.1 deraadt 73:
74: <p>
1.25 johns 75: Work on porting OpenBSD/sparc to the sun4m platform was started by Theo,
1.36 todd 76: but tendinitis problems with his wrists and the problems with the NetBSD
1.119 miod 77: core combined made him stop this work. The initial sun4m work was passed
1.7 deraadt 78: to Aaron Brown of Harvard, who was paid out of Margo Seltzer's research
1.119 miod 79: funds. This initial stuff consisted mostly of a few attempts at building
1.8 deraadt 80: pmap structure that could support all 3 MMU types efficiently. Also,
1.119 miod 81: David Miller of the UltraLinux project got a little bit involved.
1.7 deraadt 82:
83: <p>
1.27 downsj 84: Theo and Jason Downs merged the NetBSD sparc code back into OpenBSD, making
1.50 jason 85: OpenBSD/sparc usable again. Jason Wright wrote a few new SBus Ethernet
1.119 miod 86: drivers with information from the UltraLinux project and has merged a few bits
1.50 jason 87: from NetBSD sources to improve the stability of this architecture.
1.119 miod 88: Over the time, Art Grabowski fixed various stability or reliability issues,
89: and added non-executable stack and heap on sun4m machines.
90: The frame buffer and console code was completely overhauled for OpenBSD 3.2,
91: improving display speed with some frame buffers, and supporting more cards.

1.237 bentley 95: <h3 id="status"><strong>Current status:</strong></h3>
1.28 downsj 96:
1.1 deraadt 97: <p>
1.119 miod 98: Currently, all the hardware listed in the
1.154 nick 99: <a href="#hardware">supported hardware</a> section below boots
1.119 miod 100: multi-user, and supports enough (if not all) of the on-board devices to
1.153 pedro 101: be generally usable.
1.129 miod 102: A growing set of third-party SBus cards are also supported.
1.50 jason 103:
104: <p>
1.169 matthieu 105: The X Window System works on all supported frame buffers, including
1.119 miod 106: multi-head configurations.
107: No accelerated server is provided at the moment, although this is being
108: worked on.
1.6 downsj 109:
110: <p>
1.25 johns 111: An important note about OpenBSD/sparc is that it is designed so that
1.237 bentley 112: a single kernel can run on <strong>ALL SUPPORTED</strong> SPARC machines. Whereas
113: SunOS and Solaris have always had separate 'kernel architectures', i.e. sun4,
114: sun4c, sun4e and sun4m, the same 'GENERIC' OpenBSD kernel will run on all the
1.239 deraadt 115: supported models.
1.15 grr 116:
117: <p>
1.50 jason 118: Most of the problems with OpenBSD/sparc are believed to stem from the wide
1.167 jsg 119: variety of SPARC processor and cache implementations along with their
1.161 jsg 120: undocumented bugs, rather than general kernel problems.
1.15 grr 121: Feedback on which models do and do not work reliably is
1.77 deraadt 122: appreciated, particularly with newer models or upgrades.
