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.
