1.1 miod 23: OpenBSD/loongson is a port intended to run on systems based upon the
24: Loongson (also known as <i>Godson</i>) 2E and 2F MIPS-compatible processors,
25: using the
1.51 tj 26: <a href="http://www.opsycon.se/PMON2000/Main">PMON</a> firmware and boot loader.

1.1 miod 32: <p>
33: The idea of an OpenBSD/loongson started when the EMTEC Gdium Liberty netbook
34: was announced. Unfortunately, the general availability of these machines kept
1.2 miod 35: being delayed. Because of this, focus switched to the Lemote Yeeloong netbook
1.16 deraadt 36: instead. After procrastinating for months, serious work started in August 2009,
1.11 jsg 37: and the kernel work was completed by the end of November 2009.
1.1 miod 38: <p>
39: Unfortunately, most of the Loongson 2F-based hardware available at that time
40: suffers from serious problems in the processor's branch prediction logic,
1.20 miod 41: causing the system to freeze, for which <b>errata information only exists
1.37 bcallah 42: in the Chinese documentation</b> (chapter 15, missing from the English
43: translation), the only English language information being an

1.1 miod 45: on a toolchain mailing-list.
46: <p>
47: After a rush of adding silicon problems workarounds, the port to the Lemote
1.11 jsg 48: Yeeloong was completed and self hosting by the end of January 2010.
1.10 miod 49: <p>
50: This solid foundation allowed for support for other designs to be added
51: pretty quickly, over the next couple of weeks.

1.10 miod 59: The OpenBSD/loongson kernel has generic support for systems built with either
60: Loongson 2E processors and Algorithmics Bonito64 PCI and memory controller,
61: or Loongson 2F processors with their integrated PCI/PCI-X and memory controller.
1.1 miod 62: Specific hardware support is then written on a design-by-design basis.
