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,
1.20 miod 60: causing the system to freeze, for which <b>errata information only exists
61: in the chinese documentation</b> (chapter 15, missing from the english
62: translation), the only english language information being an
1.1 miod 63: <a href="http://sourceware.org/ml/binutils/2009-11/msg00387.html">e-mail</a>
64: on a toolchain mailing-list.
65: <p>
66: After a rush of adding silicon problems workarounds, the port to the Lemote
1.11 jsg 67: Yeeloong was completed and self hosting by the end of January 2010.
1.10 miod 68: <p>
69: This solid foundation allowed for support for other designs to be added
70: pretty quickly, over the next couple of weeks.
71: <p>
72: And work continues...

76: <h3><font color="#0000e0"><strong>Supported hardware:</strong></font></h3>
77: <p>
1.10 miod 78: The OpenBSD/loongson kernel has generic support for systems built with either
79: Loongson 2E processors and Algorithmics Bonito64 PCI and memory controller,
80: or Loongson 2F processors with their integrated PCI/PCI-X and memory controller.
1.1 miod 81: Specific hardware support is then written on a design-by-design basis.
82: <p>
83: At the moment, the following machines are supported:
