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
31: <a href="http://www.pmon2000.com/">PMON</a> firmware and boot loader.
32:
33: <p>
34: The current port maintainer is Miod Vallat
35: (<a href="mailto:miod@openbsd.org">miod@openbsd.org</a>).

50: <h3><font color="#0000e0"><strong>History:</strong></font></h3>
51: <p>
52: The idea of an OpenBSD/loongson started when the EMTEC Gdium Liberty netbook
53: was announced. Unfortunately, the general availability of these machines kept
1.2 miod 54: being delayed. Because of this, focus switched to the Lemote Yeeloong netbook
1.1 miod 55: instead. After procrastinating for months, serious work started in august 2009,
56: and the kernel work was completed by the end of november 2009.
57: <p>
58: Unfortunately, most of the Loongson 2F-based hardware available at that time
59: suffers from serious problems in the processor's branch prediction logic,
60: causing the system to freeze, for which <b>no errata has been published</b>
61: except for an
62: <a href="http://sourceware.org/ml/binutils/2009-11/msg00387.html">e-mail</a>
63: on a toolchain mailing-list.
64: <p>
65: After a rush of adding silicon problems workarounds, the port to the Lemote
1.2 miod 66: Yeeloong was completed and self hosting by the end of january 2010.

70: <h3><font color="#0000e0"><strong>Supported hardware:</strong></font></h3>
71: <p>
72: The OpenBSD/loongson kernel has generic support for Loongson 2E and Loongson 2F
73: processors, as well as the 2F integrated PCI and memory controller.
74: Specific hardware support is then written on a design-by-design basis.
75: <p>
76: At the moment, the following machines are supported:
77: <ul>
1.2 miod 78: <li><a href="http://www.lemote.com/english/yeeloong.html">Lemote Yeeloong</a>
1.1 miod 79: <br>
80: Both the 8.9" and 10" models are supported.
81: All on-board devices but the audio controller are supported.
1.9 ! otto 82: <li><a href="http://www.lemote.com/english/fuloong.html">Lemote Fuloong mini-PC</a>
! 83: <br>
! 84: All onboard devices but the audio controller, framebuffer and infrared port
! 85: are supported. The console must be on the serial port.
1.6 miod 86: <li><a href="http://www.gdium.com/en/product/liberty1000">EMTEC Gdium Liberty 1000</a>
87: <br>
1.8 miod 88: All on-board devices but the wireless network interface and the audio controller
89: are supported.
1.7 miod 90: (note that the on-board SD card reader does not support cards larger than 2GB)

96:
97: <p>
98: Development is currently pretty hectic at the moment, although it will slow
99: down in preparation for the first OpenBSD/loongson release.
100: <p>
101: All supported systems run multiuser, and a currently unaccelerated
102: X server is available.

107: </strong></font></h3>
108:
109: <ul>
110: <li>Write a PMON-based bootloader able to load the kernel from a BSD filesystem,
111: instead of having to put the kernel file on a Linux filesystem.
1.6 miod 112: <li>Improve installation procedure, which is still rough at the moment.
113: <li>Extend kernel ext2fs support to be able to mount Gdium filesystems
114: from OpenBSD.
1.9 ! otto 115: <li>Write support for the onboard audio controller on Yeeloong,
! 116: Fuloong and Gdium.
1.6 miod 117: <li>Fix 2D acceleration code on Gdium Liberty 1000.
1.9 ! otto 118: <li>Write a driver for the Sis 315 Pro framebuffer found on the Fuloong.
