1.1 miod 27: OpenBSD/loongson is a port intended to run on systems based upon the
28: Loongson (also known as <i>Godson</i>) 2E and 2F MIPS-compatible processors,
29: using the
30: <a href="http://www.pmon2000.com/">PMON</a> firmware and boot loader.

45: <p>
46: The idea of an OpenBSD/loongson started when the EMTEC Gdium Liberty netbook
47: was announced. Unfortunately, the general availability of these machines kept
1.2 miod 48: being delayed. Because of this, focus switched to the Lemote Yeeloong netbook
1.16 deraadt 49: instead. After procrastinating for months, serious work started in August 2009,
1.11 jsg 50: and the kernel work was completed by the end of November 2009.
1.1 miod 51: <p>
52: Unfortunately, most of the Loongson 2F-based hardware available at that time
53: suffers from serious problems in the processor's branch prediction logic,
1.20 miod 54: causing the system to freeze, for which <b>errata information only exists
1.37 bcallah 55: in the Chinese documentation</b> (chapter 15, missing from the English
56: translation), the only English language information being an
1.1 miod 57: <a href="http://sourceware.org/ml/binutils/2009-11/msg00387.html">e-mail</a>
58: on a toolchain mailing-list.
59: <p>
60: After a rush of adding silicon problems workarounds, the port to the Lemote
1.11 jsg 61: Yeeloong was completed and self hosting by the end of January 2010.
1.10 miod 62: <p>
63: This solid foundation allowed for support for other designs to be added
64: pretty quickly, over the next couple of weeks.
65: <p>
66: And work continues...

70: <h3><font color="#0000e0"><strong>Supported hardware:</strong></font></h3>
71: <p>
1.10 miod 72: The OpenBSD/loongson kernel has generic support for systems built with either
73: Loongson 2E processors and Algorithmics Bonito64 PCI and memory controller,
74: or Loongson 2F processors with their integrated PCI/PCI-X and memory controller.
1.1 miod 75: Specific hardware support is then written on a design-by-design basis.
76: <p>
77: At the moment, the following machines are supported:
