Some devices support a "USB powershare" feature where the system will continue to provide power via the USB ports when hibernating or powered off. Add support for this feaure.

|
|
Description:
|
|
Allows userspace applications to set the configurable TGP offset on top of the base
|
|
TGP. Base TGP and max TGP and therefore the max cTGP offset are device specific.
|
|
Note that setting the maximum cTGP leaves no window open for Dynamic Boost as
|
|
Dynamic Boost also can not go over max TGP. Setting the cTGP to maximum is
|
|
effectively disabling Dynamic Boost and telling the device to always prioritize the
|
|
GPU over the CPU.
|
|
|
|
Reading this file returns the current configurable TGP offset.
