Uniwill laptop extra features
4+
=============================
5+
6+
On laptops manufactured by Uniwill (either directly or as ODM), the ``uniwill-laptop`` driver
7+
handles various platform-specific features.
8+
9+
Module Loading
10+
--------------
11+
12+
The ``uniwill-laptop`` driver relies on a DMI table to automatically load on supported devices.
13+
When using the ``force`` module parameter, this DMI check will be omitted, allowing the driver
14+
to be loaded on unsupported devices for testing purposes.
15+
16+
Hotkeys
17+
-------
18+
19+
Usually the FN keys work without a special driver. However as soon as the ``uniwill-laptop`` driver
20+
is loaded, the FN keys need to be handled manually. This is done automatically by the driver itself.
21+
22+
Keyboard settings
23+
-----------------
24+
25+
The ``uniwill-laptop`` driver allows the user to enable/disable:
26+
27+
- the FN and super key lock functionality of the integrated keyboard
28+
- the touchpad toggle functionality of the integrated touchpad
29+
30+
See Documentation/ABI/testing/sysfs-driver-uniwill-laptop for details.
31+
32+
Hwmon interface
33+
---------------
34+
35+
The ``uniwill-laptop`` driver supports reading of the CPU and GPU temperature and supports up to
36+
two fans. Userspace applications can access sensor readings over the hwmon sysfs interface.
37+
38+
Platform profile
39+
----------------
40+
41+
Support for changing the platform performance mode is currently not implemented.
42+
43+
Battery Charging Control
44+
------------------------
45+
46+
The ``uniwill-laptop`` driver supports controlling the battery charge limit. This happens over
47+
the standard ``charge_control_end_threshold`` power supply sysfs attribute. All values
48+
between 1 and 100 percent are supported.
49+
50+
Additionally the driver signals the presence of battery charging issues through the standard
51+
``health`` power supply sysfs attribute.
52+
53+
Lightbar
54+
--------
55+
56+
The ``uniwill-laptop`` driver exposes the lightbar found on some models as a standard multicolor
57+
LED class device. The default name of this LED class device is ``uniwill:multicolor:status``.
58+
59+
See Documentation/ABI/testing/sysfs-driver-uniwill-laptop for details on how to control the various
60+
animation modes of the lightbar.
