But I'm interested ina kernel -> user *initiated* connection, is there anything outthere? I have a kext that needs to initiate communication with an user process. I can alternatively let the user process initiate the connection in one of the above ways and then pass a data pool pointer, but that would be a lot harder. IS there anything I can do or use to initiate a kernel -> user crossing without user parts help? Not really. Do you have a user land app that you are talking to? If so it is pretty easy to emulate a kernel initiated event. What do you want to happen in user land when the kernel hits something. I guess what I'm asking is what problem are you actually trying to solve.
