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
1.51 tj 31: <a href="http://www.opsycon.se/PMON2000/Main">PMON</a> firmware and boot loader.

1.1 miod 37: <p>
38: The idea of an OpenBSD/loongson started when the EMTEC Gdium Liberty netbook
39: was announced. Unfortunately, the general availability of these machines kept
1.2 miod 40: being delayed. Because of this, focus switched to the Lemote Yeeloong netbook
1.16 deraadt 41: instead. After procrastinating for months, serious work started in August 2009,
1.11 jsg 42: and the kernel work was completed by the end of November 2009.
1.1 miod 43: <p>
44: Unfortunately, most of the Loongson 2F-based hardware available at that time
45: suffers from serious problems in the processor's branch prediction logic,
1.20 miod 46: causing the system to freeze, for which <b>errata information only exists
1.37 bcallah 47: in the Chinese documentation</b> (chapter 15, missing from the English
48: translation), the only English language information being an

51: <p>
52: After a rush of adding silicon problems workarounds, the port to the Lemote
1.11 jsg 53: Yeeloong was completed and self hosting by the end of January 2010.
1.10 miod 54: <p>
55: This solid foundation allowed for support for other designs to be added
56: pretty quickly, over the next couple of weeks.
57: <p>
58: And work continues...

1.10 miod 64: The OpenBSD/loongson kernel has generic support for systems built with either
65: Loongson 2E processors and Algorithmics Bonito64 PCI and memory controller,
66: or Loongson 2F processors with their integrated PCI/PCI-X and memory controller.
1.1 miod 67: Specific hardware support is then written on a design-by-design basis.
