1.3 fn 36:
37: <p>
1.126 jufi 38: The original 4.4BSD port was done by Chris Torek as a contract to
1.50 jason 39: LBL. The code was released by Chris in mid-1993, and Theo de Raadt
1.1 deraadt 40: worked it into shape for the NetBSD tree. Theo and Markus Wild worked
41: on improving Chris' original SunOS compatibility code into a highly
42: complete and reliable emulation. Chuck Cranor ported the sun4c code to
1.119 miod 43: the 8KB pagesize sun4 architecture, and Theo merged this code in a
1.1 deraadt 44: way that would allow the same kernel and programs to run on either
1.64 jason 45: sun4c or sun4 machines (unlike Sun's separate kernel environments).
1.1 deraadt 46: This last change also required a rewrite of the device configuration
1.25 johns 47: code. Just after the NetBSD/sparc 1.0 release, Peter Galbavy wrote an
1.154 nick 48: ESP SCSI device driver as a replacement for Chris' sparc-specific SCSI
1.119 miod 49: code.
1.3 fn 50: </p>
1.1 deraadt 51:
52: <p>
53: At this point a conflict emerged between Theo and the other people he
54: started the NetBSD project with, and Theo was forced by the core group
55: to resign from NetBSD. After Theo left NetBSD, a few people in the
56: NetBSD group did some other things for the port: Paul Kranenburg
57: ported a floppy driver and started writing support for the 4/400.
58: Chuck spent many long hours working on the ie, xy, xd device drivers.
1.3 fn 59: </p>
1.1 deraadt 60:
61: <p>
62: Theo continued working independently, and made a number of additions:
1.119 miod 63: P4 support, flexible boot strategy, a few graphics drivers with the help
64: from John Stone, and masses of bug fixes.
1.3 fn 65: </p>
1.1 deraadt 66:
67: <p>
1.25 johns 68: Work on porting OpenBSD/sparc to the sun4m platform was started by Theo,
1.36 todd 69: but tendinitis problems with his wrists and the problems with the NetBSD
1.119 miod 70: core combined made him stop this work. The initial sun4m work was passed
1.7 deraadt 71: to Aaron Brown of Harvard, who was paid out of Margo Seltzer's research
1.119 miod 72: funds. This initial stuff consisted mostly of a few attempts at building
1.8 deraadt 73: pmap structure that could support all 3 MMU types efficiently. Also,
1.119 miod 74: David Miller of the UltraLinux project got a little bit involved.
1.7 deraadt 75: </p>
76:
77: <p>
1.27 downsj 78: Theo and Jason Downs merged the NetBSD sparc code back into OpenBSD, making
1.50 jason 79: OpenBSD/sparc usable again. Jason Wright wrote a few new SBus Ethernet
1.119 miod 80: drivers with information from the UltraLinux project and has merged a few bits
1.50 jason 81: from NetBSD sources to improve the stability of this architecture.
1.119 miod 82: Over the time, Art Grabowski fixed various stability or reliability issues,
83: and added non-executable stack and heap on sun4m machines.
84: The frame buffer and console code was completely overhauled for OpenBSD 3.2,
85: improving display speed with some frame buffers, and supporting more cards.
1.50 jason 86: </p>

1.119 miod 97: Currently, all the hardware listed in the
1.154 nick 98: <a href="#hardware">supported hardware</a> section below boots
1.119 miod 99: multi-user, and supports enough (if not all) of the on-board devices to
1.153 pedro 100: be generally usable.
1.129 miod 101: A growing set of third-party SBus cards are also supported.
1.50 jason 102: </p>

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: </p>
110:
111: <p>
1.25 johns 112: An important note about OpenBSD/sparc is that it is designed so that
1.167 jsg 113: a single kernel can run on <b>ALL SUPPORTED</b> SPARC machines. Whereas
1.92 jufi 114: SunOS and Solaris have always had separate `kernel architectures', i.e. sun4,
1.196 miod 115: sun4c, sun4e and sun4m, the same `GENERIC' OpenBSD kernel will run on all the
1.26 downsj 116: supported models.
1.15 grr 117: </p>
118:
119: <p>
1.50 jason 120: Most of the problems with OpenBSD/sparc are believed to stem from the wide
1.167 jsg 121: variety of SPARC processor and cache implementations along with their
1.161 jsg 122: undocumented bugs, rather than general kernel problems.
1.15 grr 123: Feedback on which models do and do not work reliably is
1.77 deraadt 124: appreciated, particularly with newer models or upgrades.
