21: OpenBSD/loongson is a port intended to run on systems based upon the

38:
1.1 miod 39: <p>
40: The idea of an OpenBSD/loongson started when the EMTEC Gdium Liberty netbook
41: was announced. Unfortunately, the general availability of these machines kept
1.2 miod 42: being delayed. Because of this, focus switched to the Lemote Yeeloong netbook
1.16 deraadt 43: instead. After procrastinating for months, serious work started in August 2009,
1.11 jsg 44: and the kernel work was completed by the end of November 2009.
1.64 bentley 45:
1.1 miod 46: <p>
47: Unfortunately, most of the Loongson 2F-based hardware available at that time
48: suffers from serious problems in the processor's branch prediction logic,
1.20 miod 49: causing the system to freeze, for which <b>errata information only exists
1.37 bcallah 50: in the Chinese documentation</b> (chapter 15, missing from the English
51: translation), the only English language information being an
1.50 mmcc 52: <a href="http://sourceware.org/ml/binutils/2009-11/msg00387.html">email</a>
1.1 miod 53: on a toolchain mailing-list.

1.1 miod 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.
1.64 bentley 58:
1.10 miod 59: <p>
60: This solid foundation allowed for support for other designs to be added
61: pretty quickly, over the next couple of weeks.

1.10 miod 71: The OpenBSD/loongson kernel has generic support for systems built with either
72: Loongson 2E processors and Algorithmics Bonito64 PCI and memory controller,
73: or Loongson 2F processors with their integrated PCI/PCI-X and memory controller.
1.1 miod 74: Specific hardware support is then written on a design-by-design basis.
