Direct Rendering on Fulong

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:
  1. [drm] Initialized radeon 1.27.0 20060524 on minor 0
复制代码


and there's the right nodes created in /dev:
  1. taijia ~ # ls -l /dev/dri/
  2. total 0
  3. crw-rw---- 1 root video 226, 0 2007-10-04 18:35 card0
复制代码


X sees that there is DRI possibly on offer, but then fails to set it up:
  1. (**) RADEON(0): RADEONScreenInit 14000000 0
  2. (**) RADEON(0): Map: 0x14000000, 0x01000000

  36. (EE) RADEON(0): [dri] DRIScreenInit failed.  Disabling DRI.

The end result is yes, I have OpenGL... in software:
  1. taijia ~ # glxinfo
  2. name of display: :0.0
  3. display: :0  screen: 0
  4. direct rendering: No

I'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.

I hope that the newly designed 2F boxes will solve these problem.

I have sent you what I could salvage from the forums but when I built 2.6.18.1 with the DRM kernel patch it crashed. I value stability over the latest and greatest so I'm using 2.6.18.1 now and Xorg is running without DRI support and therefore some sluggishness. Still I'd much rather run a current kernel, particularly since 2.6.18.1 corrupts XFS file systems.

It would be a lot better to get the DRM kernel patch integrated into the MIPS kernel sources if it still correct and applicable and not just a hack or rewrite it and then put up for submission to the MIPS maintainer (Ralf Baechle). I don't know if power management will ever work because support for it may be absent from the chipset.

At the user level OpenOffice.org and Java support are a bit behind the times but the blame is with these projects and not with the various MIPS distribution maintainers (of which you and I are only two) nor Lemote. Therefore I have filed issues for OpenOffice.org Linux/MIPS support and signed JCA/SCA to have my patches possibly included in these projects as well.

For Flash support Gnash is improving every day and Lguest/KVM-lite might even make virtualisation possible on MIPS as it will for x86 processors without virtualisation support.

jamesr: What I hear about the Loongson 2F... they'll be awesome.   I'd seriously consider purchasing a laptop based on a Loongson 2F or Loongson 3.

psychicist: I'm running Gentoo's mips-sources-2.6.22.6 with Lemote's patches applied presently, and found it quite stable even with the DRM driver loaded... just between radeon.ko, xf86-video-ati and xorg-server... none of them are talking to eachother.

The kernel binary is on my site (see the hyperlink: 主页 above)... if you're interested.

Not meant to hijack this thread but I am curious how you got your fulong box. I have been thinking getting one for a while. Is there any retailer in Australia? I live in Sydney btw.

This has also been done.
