[Openchrome-users] Some general questions

Hi,

OK, I'll keep trying then.

Well, thanks for your answers anyway!

Ah, this is the 'old branch' stuff at unichrome.sf.net.

It might be a bit sensitive, but what is the relation between the
unichrome project on sf.net and the OpenChrome project? It seems like
first the stuff from the former was entering Xorg and nowadays the
latter stuff goes into Xorg. Why?

Is there a difference in 2D features you think? (Maybe not all 2D ops
were accelerated yet or so?)

Any idea about 2D?

OK.

How do I make sure that the proper one is loaded? If via_dri.so isn't
used, why is it in Xorg?

I'm supposed to show that hardware acceleration (at least 2D, preferably
3D as well) can work on MontaVista Linux 4.0.1, which comes with Xorg
6.8.2 and a 2.6.10 kernel.
So, I compiled the via DRM kernel module for 2.6.10 (got the sources
from some site, but it seems to load fine) and I tweaked the source RPM
for Xorg (6.8.2) from MontaVista to use the via driver. So far, it
doesn't seem to use the DRI at all. Still working on it..
(Any ideas welcome!)

Is there some HOWTO or guide that shows me how to "patch in OpenChrome"
in Xorg 6.9, e.g.? I assume you mean the latest SVN version?
