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?
