The KIP subsystem (full name unknown, abbreviation has been obtained through reverse engineering) handles detachable peripherals such as the keyboard cover on the Surface Pro X and Surface Pro 8. It is currently not entirely clear what this subsystem entails, but at the very least it provides event notifications for when the keyboard cover on the Surface Pro X and Surface Pro 8 have been detached or re-attached, as well as the state that the keyboard cover is currently in (e.g. folded-back, folded laptop-like, closed, etc.).
