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.

1.1 miod 43: <p>
44: The idea of an OpenBSD/loongson started when the EMTEC Gdium Liberty netbook
45: was announced. Unfortunately, the general availability of these machines kept
1.2 miod 46: being delayed. Because of this, focus switched to the Lemote Yeeloong netbook
1.16 deraadt 47: instead. After procrastinating for months, serious work started in August 2009,
1.11 jsg 48: and the kernel work was completed by the end of November 2009.
1.1 miod 49: <p>
50: Unfortunately, most of the Loongson 2F-based hardware available at that time
51: suffers from serious problems in the processor's branch prediction logic,
1.20 miod 52: causing the system to freeze, for which <b>errata information only exists
1.37 bcallah 53: in the Chinese documentation</b> (chapter 15, missing from the English
54: translation), the only English language information being an
1.1 miod 55: <a href="http://sourceware.org/ml/binutils/2009-11/msg00387.html">e-mail</a>
56: on a toolchain mailing-list.
57: <p>
58: After a rush of adding silicon problems workarounds, the port to the Lemote
1.11 jsg 59: Yeeloong was completed and self hosting by the end of January 2010.
1.10 miod 60: <p>
61: This solid foundation allowed for support for other designs to be added
62: pretty quickly, over the next couple of weeks.
63: <p>
64: And work continues...

1.1 miod 69: <p>
1.10 miod 70: The OpenBSD/loongson kernel has generic support for systems built with either
71: Loongson 2E processors and Algorithmics Bonito64 PCI and memory controller,
72: or Loongson 2F processors with their integrated PCI/PCI-X and memory controller.
1.1 miod 73: Specific hardware support is then written on a design-by-design basis.
74: <p>
75: At the moment, the following machines are supported:
