acpisurface driver provides ACPI
support for Microsoft Surface Book laptops. It responds to various button
presses such as volume up/down and power buttons, all of which are located
on the top of the tablet/detachable display. It does not provide support for
the hotkeys in the keyboard/base unit.
Volume up/down button presses are routed to the master system mixer via the wscons(4) subsystem. Power button presses result in a soft power off request being queued by the acpi(4) subsystem.
