| 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. |
