OK, I built XFree86 4.0.2 and DRI seems to be working for me now under 2.4.0-ac4. (Starting with 2.4.0, it wouldn't, this is with an ATI XPert 2000 AGP).
BUT - although /var/log/XFree86.0.log documents the startup of DRI, DRM and AGP, and states the info about their initialization and stuff so that it looks like they're working, I don't notice any performance difference running any of the Mesa-3.4 demos whether or not I use DRI, and whether I run 4.0.1 or 4.0.2.
This makes me suspect it's not really working, or else my build of the Mesa-3.4 library wasn't configured right - but note that if I disable DRI, one of the Mesa demos will comment that it's not available.
A specific example is Mesa-3.4/demos/gloss. It's a rotating textured cylinder that is partially reflective of what seems to be a landscape that is in front of the screen being reflecting back to the viewer. I get a pretty consistent 7.5 frames per second:
- in 4.0.1 with no DRI - in 4.0.1 with DRI - in 4.0.2 with no DRI - in 4.0.2 with DRI
Having agpgart and drm/r128 compiled in or as modules also doesn't appear to make a difference.
The frame rate for gloss drops to about 3.5 if I run geartrain (another demo) alongside it. Geartrain by itself seems to be about the same speed in all cases, though it doesn't report a number.
There are a couple benchmarking tools in Mesa if someone wanted hard numbers from me.
Can anyone suggest any 3D code that I can download that does more complex things than the mesa demos that I can test this with?
Is my DRI really working? If not, any tips on getting it to do so?
