+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.
