Then the open graphics card can be simulated by a .so file that qemu loads. This would be VERY useful to other people who develop PCI hardware. There needs to be a special version of the plugin that interfaces with a verilog simulator, possibly over a socket, so the Verilog hardware model can be substituted for the C hardware model. Or so they can be cosimulated and any discrepancies detected. I imagine the interface should be modelled very closely on PCI, but not at the level of individual signals, of course, but rather on the level of "here's a write of 6 bytes to that address, here's a read, here's a configuration space write, ..." -Peter _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
