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 ABI file 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 ABI file testing/sysfs-driver-uniwill-laptop for details on how to control the various animation modes of the lightbar.
