1.1 miod 28: OpenBSD/loongson is a port intended to run on systems based upon the
29: Loongson (also known as <i>Godson</i>) 2E and 2F MIPS-compatible processors,
30: using the
31: <a href="http://www.pmon2000.com/">PMON</a> firmware and boot loader.
32:
33: <p>
34: The current port maintainer is Miod Vallat
35: (<a href="mailto:miod@openbsd.org">miod@openbsd.org</a>).

51: <p>
52: The idea of an OpenBSD/loongson started when the EMTEC Gdium Liberty netbook
53: was announced. Unfortunately, the general availability of these machines kept
1.2 miod 54: being delayed. Because of this, focus switched to the Lemote Yeeloong netbook
1.16 deraadt 55: instead. After procrastinating for months, serious work started in August 2009,
1.11 jsg 56: and the kernel work was completed by the end of November 2009.
1.1 miod 57: <p>
58: Unfortunately, most of the Loongson 2F-based hardware available at that time
59: suffers from serious problems in the processor's branch prediction logic,
60: causing the system to freeze, for which <b>no errata has been published</b>
61: except for an
62: <a href="http://sourceware.org/ml/binutils/2009-11/msg00387.html">e-mail</a>
63: on a toolchain mailing-list.
64: <p>
65: After a rush of adding silicon problems workarounds, the port to the Lemote
1.11 jsg 66: Yeeloong was completed and self hosting by the end of January 2010.
1.10 miod 67: <p>
68: This solid foundation allowed for support for other designs to be added
69: pretty quickly, over the next couple of weeks.
70: <p>
71: And work continues...

75: <h3><font color="#0000e0"><strong>Supported hardware:</strong></font></h3>
76: <p>
1.10 miod 77: The OpenBSD/loongson kernel has generic support for systems built with either
78: Loongson 2E processors and Algorithmics Bonito64 PCI and memory controller,
79: or Loongson 2F processors with their integrated PCI/PCI-X and memory controller.
1.1 miod 80: Specific hardware support is then written on a design-by-design basis.
81: <p>
82: At the moment, the following machines are supported:
83: <ul>
1.10 miod 84: <li><a href="http://www.lemote.com/english/fuloong.html">Lemote Fuloong 2F
85: mini-PC</a>
1.9 otto 86: <br>
1.12 otto 87: All on-board devices but the audio controller, framebuffer and infrared port
1.9 otto 88: are supported. The console must be on the serial port.
1.10 miod 89: <li><a href="http://www.lemote.com/english/yeeloong.html">Lemote Yeeloong
90: netbook</a>
91: <br>
92: Both the 8.9" and 10.1" models are supported.
93: All on-board devices but the audio controller are supported.
94: <li><a href="http://www.gdium.com/en/product/liberty1000">EMTEC Gdium Liberty 1000 netbook</a>
1.6 miod 95: <br>
1.13 miod 96: All on-board devices but the audio controller are supported.
1.7 miod 97: (note that the on-board SD card reader does not support cards larger than 2GB)

105: Development is currently pretty hectic at the moment, although it will slow
106: down in preparation for the first OpenBSD/loongson release.
107: <p>
108: All supported systems run multiuser, and a currently unaccelerated
