We already have the nsc driver which AFAIK is for some Geode CPUs. > The Graphics Processor is available through AMD's Cimmarron Kernel > library, > Only Imageblit / fillrect and imageblit with Alpha are accelerated. > > If Possable, i would rather not have to write a driver, > Ideally, i would preffere to just map DirectFB's hardware accelerated > calls to the existing AMD Cimarron driver functions. I think that's basically what the nsc driver is doing. > Can anyone offer any documentation on writing DirectFB Graphics > Drivers ??? > or sugest a good place to start ? > > Im currently wading through the lastest release code, specifically the > matrox code in /gfxdrivers/matrox The matrox code is somewhat complicated and/or messy due to multiple supported hardware versions, and the sheer amount of blit options supported. It could use some cleanup. There are probably some simpler examples you can study in the beginning (maybe neomagic or tdfx). -- Ville Syrjälä [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ _______________________________________________ directfb-dev mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
