I haven't looked at the code yet but was wondering if there is any provision for pre-probing devices. specifically i'm interested in fixing the console stuff to be more modular ie. allocating a device for input and another for output for different subsystems specifically system console, DDB and GDB seperatly, it seems like after this new code i will have to start from scratch, i'm just hoping there will be a way to do this and to notify a device that it has already been probed or allocated for something else. is this possible?
