So my question to you is: what is the current maximum latency allowed by the current OGP design ? And is it critical in a typical x86 system
Like I say, I've been working with graphics cards and drivers since 1996. We never had a problem then, and we're especially not going to have a problem now, with 11 years of advancement. I think other aspects of the system behavior will have a greater impact on OGA than will interrupt latency. Multitasking, for instance. Keep in mind that user processes will be deciding what the graphics card does, and they don't get exclusive access to the CPU. The only performance-critical interrupt-related things will involve drawing, and we'll time our interrupts so as to be sure that the GPU is still busy working on old stuff long after we interrupt the host and ask for more. -- Timothy Normand Miller http://www.cse.ohio-state.edu/~millerti Open Graphics Project _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
