SPDX-License-Identifier: GPL-2.0+ + +Uniwill laptop extra features +============================= + +On laptops manufactured by Uniwill (either directly or as ODM), the ``uniwill-laptop`` driver +handles various platform-specific features. + +Module Loading +-------------- + +The ``uniwill-laptop`` driver relies on a DMI table to automatically load on supported devices. +When using the ``force`` module parameter, this DMI check will be omitted, allowing the driver +to be loaded on unsupported devices for testing purposes. + +Hotkeys +------- + +Usually the FN keys work without a special driver. However as soon as the ``uniwill-laptop`` driver +is loaded, the FN keys need to be handled manually. This is done automatically by the driver itself. + +Keyboard settings +----------------- + +The ``uniwill-laptop`` driver allows the user to enable/disable: + + - the FN and super key lock functionality of the integrated keyboard + - the touchpad toggle functionality of the integrated touchpad + +See Documentation/ABI/testing/sysfs-driver-uniwill-laptop for details. + +Hwmon interface +--------------- + +The ``uniwill-laptop`` driver supports reading of the CPU and GPU temperature and supports up to +two fans. Userspace applications can access sensor readings over the hwmon sysfs interface. + +Platform profile +---------------- + +Support for changing the platform performance mode is currently not implemented. + +Battery Charging Control +------------------------ + +The ``uniwill-laptop`` driver supports controlling the battery charge limit. This happens over +the standard ``charge_control_end_threshold`` power supply sysfs attribute. All values +between 1 and 100 percent are supported. + +Additionally the driver signals the presence of battery charging issues through the standard +``health`` power supply sysfs attribute. + +Lightbar +-------- + +The ``uniwill-laptop`` driver exposes the lightbar found on some models as a standard multicolor +LED class device. The default name of this LED class device is ``uniwill:multicolor:status``. + +See Documentation/ABI/testing/sysfs-driver-uniwill-laptop for details on how to control the various +animation modes of the lightbar. |
