Hi All...
Just wondering if anyone knew how to get Direct Rendering going on the Fulong. I've been tinkering for the last few months on this... and it's only recently that I've had any decent OpenGL apps to test with.
Just recently, I managed to get Quake II running -- the games-fps/quake2-icculus works on MIPS with
a few minor modifications. I have it going using Software mode at a resolution of 400×300px. Not terrific, but still quite workable.
The attachment here shows it running in software mode.
I'm close to getting a workable boot environment for Gentoo/MIPS on the Lemote systems... and I figured a demo of Quake II would make a nice touch -- if I can get hardware OpenGL going. I know it can be done, since I've seen others getting Beryl going on these boxes.
At present, I'm using the patches I have in the
Gentoo Loongson overlay... the DRM driver is loaded:

EndSectionI've seen some threads on getting this working... some even with patches, but the patches seem to have been mangled by the forum software, thus I'm not able to extract them from the page. There are only 3 things on these Lemote boxes I haven't managed to get working:
- Power management (turning the power off)
- OpenGL
- Infrared port (near the speaker-out socket and HDD LED -- this is a low priority thing)
Everything else works flawlessly. For this release of Gentoo, I'd dearly love to get all the major pieces of hardware working fully. If anyone knows of some patches I might've missed, or something I've otherwise done incorrect... please let me know.
