Look at any i2c driver. Implement the i2c driver interface and instead of directly writing to hardware registers write to something else. Same for read... E.g. Your i2c emulator could have a TCP back-end. Host<->Guest i2c pass-through is also possible. BTW: All this is not UML specific. Iff it makes sense for only UML we can put it into arch/um/drivers/. Otherwise drivers/ is fine. > Or is this something that is not really desired by the uml project? If there is a use case, why not. :-) Thanks, //richard
