Select this option to enable the Hardware Feedback Interface. If
selected, hardware provides guidance to the operating system on
the performance and energy efficiency capabilities of each CPU.
These capabilities may change as a result of changes in the operating
conditions of the system such power and thermal limits. If selected,
the kernel relays updates in CPUs' capabilities to userspace.
