- 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 lock and super key 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.
