1.1 miod 25: OpenBSD/loongson is a port intended to run on systems based upon the
26: Loongson (also known as <i>Godson</i>) 2E and 2F MIPS-compatible processors,
27: using the
28: <a href="http://www.pmon2000.com/">PMON</a> firmware and boot loader.

1.1 miod 41: <p>
42: The idea of an OpenBSD/loongson started when the EMTEC Gdium Liberty netbook
43: was announced. Unfortunately, the general availability of these machines kept
1.2 miod 44: being delayed. Because of this, focus switched to the Lemote Yeeloong netbook
1.16 deraadt 45: instead. After procrastinating for months, serious work started in August 2009,
1.11 jsg 46: and the kernel work was completed by the end of November 2009.
1.1 miod 47: <p>
48: Unfortunately, most of the Loongson 2F-based hardware available at that time
49: suffers from serious problems in the processor's branch prediction logic,
1.20 miod 50: causing the system to freeze, for which <b>errata information only exists
1.37 bcallah 51: in the Chinese documentation</b> (chapter 15, missing from the English
52: translation), the only English language information being an

1.1 miod 54: on a toolchain mailing-list.
55: <p>
56: After a rush of adding silicon problems workarounds, the port to the Lemote
1.11 jsg 57: Yeeloong was completed and self hosting by the end of January 2010.
1.10 miod 58: <p>
59: This solid foundation allowed for support for other designs to be added
60: pretty quickly, over the next couple of weeks.
61: <p>
62: And work continues...

1.1 miod 67: <p>
1.10 miod 68: The OpenBSD/loongson kernel has generic support for systems built with either
69: Loongson 2E processors and Algorithmics Bonito64 PCI and memory controller,
70: or Loongson 2F processors with their integrated PCI/PCI-X and memory controller.
1.1 miod 71: Specific hardware support is then written on a design-by-design basis.
72: <p>
73: At the moment, the following machines are supported:
