General informations

The Linux kernel configuration item CONFIG_SURFACE_DTX:

Help text

Driver for the Surface Book clipboard detachment system (DTX).

On the Surface Book series devices, the display part containing the CPU (called the clipboard) can be detached from the base (containing a battery, the keyboard, and, optionally, a discrete GPU) by (if necessary) unlocking and opening the latch connecting both parts.

This driver provides a user-space interface that can influence the behavior of this process, which includes the option to abort it in case the base is still in use or speed it up in case it is not.

Note that this module can be built without support for the Surface Aggregator Bus (i.e. SURFACE_AGGREGATOR_BUS=n). In that case, some devices, specifically the Surface Book 3, will not be supported.
