If this is an AGP chipset, they it will probably use The K8 AGPGART, with the amd64-agp,ko linux driver. The K8M800 does that. When it comes to DRM / 3D, it's probably at least a man-years worth of work to build a 3D driver from scratch. /Thomas > Regards, > Xavier > > [1] > http://www.openchrome.org/trac/wiki/Development#Hardwaredocumentation > > [2] > http://article.gmane.org/gmane.comp.video.dri.devel/32970 > http://article.gmane.org/gmane.comp.video.dri.devel/32973 > http://article.gmane.org/gmane.comp.video.dri.devel/32976 > http://article.gmane.org/gmane.comp.video.dri.devel/32978 > > [3] > http://cgit.freedesktop.org/mesa/drm/log/?h=modesetting-newttm > > > _______________________________________________ > Openchrome-devel mailing list > [email protected] > http://wiki.openchrome.org/mailman/listinfo/openchrome-devel > _______________________________________________ Openchrome-devel mailing list [email protected] http://wiki.openchrome.org/mailman/listinfo/openchrome-devel
