Surface ACPI Notify (SAN) driver for Microsoft Surface devices.
|
|
|
|
This driver provides support for the ACPI interface (called SAN) of
|
|
the Surface System Aggregator Module (SSAM) EC. This interface is used
|
|
on 5th- and 6th-generation Microsoft Surface devices (including
|
|
Surface Pro 5 and 6, Surface Book 2, Surface Laptops 1 and 2, and in
|
|
reduced functionality on the Surface Laptop 3) to execute SSAM
|
|
requests directly from ACPI code, as well as receive SSAM events and
|
|
turn them into ACPI notifications. It essentially acts as a
|
|
translation layer between the SSAM controller and ACPI.
|
|
|
|
Specifically, this driver may be needed for battery status reporting,
|
|
thermal sensor access, and real-time clock information, depending on
|
|
the Surface device in question.

Provides a misc-device interface to the Surface System Aggregator
|
|
Module (SSAM) controller.
|
|
|
|
This option provides a module (called surface_aggregator_cdev), that,
|
|
when loaded, will add a client device (and its respective driver) to
|
|
the SSAM controller. Said client device manages a misc-device
|
|
interface (/dev/surface/aggregator), which can be used by user-space
|
|
tools to directly communicate with the SSAM EC by sending requests and
|
|
receiving the corresponding responses.
|
|
|
|
The provided interface is intended for debugging and development only,
|
|
and should not be used otherwise.

|
Driver for out-of-band hot-plug event signaling on Microsoft Surface
|
|
devices with hot-pluggable PCIe cards.
|
|
|
|
This driver is used on Surface Book (2 and 3) devices with a
|
|
hot-pluggable discrete GPU (dGPU). When not in use, the dGPU on those
|
|
devices can enter D3cold, which prevents in-band (standard) PCIe
|
|
hot-plug signaling. Thus, without this driver, detaching the base
|
|
containing the dGPU will not correctly update the state of the
|
|
corresponding PCIe device if it is in D3cold. This driver adds support
|
|
for out-of-band hot-plug notifications, ensuring that the device state
|
|
is properly updated even when the device in question is in D3cold.
|
|
|
|
Select M or Y here, if you want to (fully) support hot-plugging of
|
|
dGPU devices on the Surface Book 2 and/or 3 during D3cold.
