Why all the new framework, doesn't the existing bus infrastructure provide everything you need here? Shouldn't you just be putting your cpus and memory sticks on a bus and handle stuff that way? What makes these types of devices so unique from all other devices that Linux has been handling in a dynamic manner (i.e. hotplugging them) for many many years?
Why are you reinventing the wheel?
