! 24: OpenBSD/loongson is a port intended to run on systems based upon the
! 25: Loongson (also known as <i>Godson</i>) 2E and 2F MIPS-compatible processors,
! 26: using the
! 27: <a href="http://www.pmon2000.com/">PMON</a> firmware and boot loader.
! 28:
! 29: <p>
! 30: The current port maintainer is Miod Vallat
! 31: (<a href="mailto:miod@openbsd.org">miod@openbsd.org</a>).

! 46: <h3><font color="#0000e0"><strong>History:</strong></font></h3>
! 47: <p>
! 48: The idea of an OpenBSD/loongson started when the EMTEC Gdium Liberty netbook
! 49: was announced. Unfortunately, the general availability of these machines kept
! 50: being delayed. Because of this, focus switched to the Lemote Yeelong netbook
! 51: instead. After procrastinating for months, serious work started in august 2009,
! 52: and the kernel work was completed by the end of november 2009.
! 53: <p>
! 54: Unfortunately, most of the Loongson 2F-based hardware available at that time
! 55: suffers from serious problems in the processor's branch prediction logic,
! 56: causing the system to freeze, for which <b>no errata has been published</b>
! 57: except for an
! 58: <a href="http://sourceware.org/ml/binutils/2009-11/msg00387.html">e-mail</a>
! 59: on a toolchain mailing-list.
! 60: <p>
! 61: After a rush of adding silicon problems workarounds, the port to the Lemote
! 62: Yeelong was completed and self hosting by the end of january 2010.

! 66: <h3><font color="#0000e0"><strong>Supported hardware:</strong></font></h3>
! 67: <p>
! 68: The OpenBSD/loongson kernel has generic support for Loongson 2E and Loongson 2F
! 69: processors, as well as the 2F integrated PCI and memory controller.
! 70: Specific hardware support is then written on a design-by-design basis.
! 71: <p>
! 72: At the moment, the following machines are supported:
! 73: <ul>
! 74: <li><a href="http://www.lemote.com/english/yeeloong.html">Lemote Yeelong</a>
! 75: <br>
! 76: Both the 8.9" and 10" models are supported.
! 77: All on-board devices but the audio controller are supported.
! 78: </ul>

! 82: <h3><font color="#0000e0"><strong>Current status:</strong></font></h3>
! 83:
! 84: <p>
! 85: Development is currently pretty hectic at the moment, although it will slow
! 86: down in preparation for the first OpenBSD/loongson release.
! 87: <p>
! 88: All supported systems run multiuser, and a currently unaccelerated
! 89: X server is available.

! 94: </strong></font></h3>
! 95:
! 96: <ul>
! 97: <li>Better workarounds for the 2F problems.
! 98: <li>Write a PMON-based bootloader able to load the kernel from a BSD filesystem,
! 99: instead of having to put the kernel file on a Linux filesystem.
! 100: <li>Write support for the onboard audio controller on Yeeloong.
! 101: <li>Port to other Loongson-based machines, such as the Gdium Liberty netbook and
! 102: the Lemote Fuloong mini-PC.
