Date:		January 2026

KernelVersion:	7.0

Contact:	Werner Sembach <wse@tuxedocomputers.com>

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.

Description:

		Allows userspace applications to choose the USB-C power distribution profile between

		one that offers a bigger share of the power to the battery and one that offers more

		of it to the CPU. Writing "charging"/"performance" into this file selects the

		respective profile.
