Subject: [PATCH v2 08/12] platform/surface: aggregator: Add comment for KIP subsystem category
Date: Fri, 27 May 2022 04:34:43 +0200 [thread overview]
Message-ID: <20220527023447.2460025-9-luzmaximilian@gmail.com> (raw)
In-Reply-To: <20220527023447.2460025-1-luzmaximilian@gmail.com>
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.).
