[Dri-users] SiS DRI Support

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hello all.

I'm trying to "play" with DRI support for SiS boards on xf-4_0_3 branch.

After some work, everything is loaded and the log reports it's
working, but when I try to start any app that uses it (ex. tuxracer
or quake3), I get:

SIS driver : out of video memory
Fatal errors in sis_dri.so

I'm using:
kernel 2.4.3
SiS 6326 chipset

I found no docs for SiS DRI support in the page. I found some msgs in
the mail list archieves, but they're old.

There are lot's of changes in the current XFree CVS related to DRI, but it
looks like SiS support was abandoned.

Any plans for SiS support? Anybody knows who did the actual work in the
kernel? Who is the maintainer? I would like to help in some way.

Thanks in advance.
