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. |
