I don't know, and I also think the Xpert list is probably a better place to ask. > 2) If i do hook some of the mid-level or GC-level functions, is there > any possibility to let the X11 generic routines handle the call > if do find out that hardware does not cover a specific case? > (I dont want to do duplication of software routines in a driver.) A common X way of doing something like that is to wrap the generic function, i.e. replace the function pointer in a structure and call the replaced function as necessary. Don't know if that applies to your problem though. > 3) Does someone know what the define RENDER is intended > for?

Don't tell me you haven't heard about the RENDER extension. ;) It's about image composition and related things, most popularly anti-aliased text. The mga driver has some acceleration for it, I've been trying to adapt it to the r128 driver but haven't had luck with the Rage128 CCE packets for alpha blending yet. -- Earthling Michel D�nzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
