The only example I know was inside the sp�cific KGI infrastructure: the same driver code (exactly the same) known to work for Matrox Mystique/G200/G400 on both Linux (2.4) and FreeBSD (5.x). However, the ideas behind KGI software design should easily be reused. An API abstracting the way you access registers on the board (mmio setup, actual access functions, etc.) is the first step. Providing a full Hardware Abstraction Layer may be more difficult (especially in terms of maintainability and potential for extensibility in future designs). But as the actual hardware designers may want to cooperate, that could be feasible this time. :-) Rodolphe _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
