Description:
|
|
Takeover TDP controls from the device. OneXPlayer devices have a
|
|
turbo button that can be used to switch between two TDP modes
|
|
(usually 15W and 25W). By setting this attribute to 1, this
|
|
functionality is disabled, handing TDP control over to (Windows)
|
|
userspace software and the Turbo button turns into a keyboard
|
|
shortcut over the AT keyboard of the device. In addition,
|
|
using this setting is a prerequisite for PWM control for most
|
|
newer models (otherwise it NOOPs).

Description:
|
|
Some OneXPlayer devices (e.g., X1 series) feature a little LED
|
|
nested in the Turbo button. This LED is illuminated when the
|
|
device is in the higher TDP mode (e.g., 25W). Once tt_toggle
|
|
is engaged, this LED is left dangling to its last state. This
|
|
attribute allows userspace to control the LED state manually
|
|
(either with 1 or 0). Only a subset of devices contain this LED.
