internal P-state selection logic is expected to focus entirely on performance.

This will override the EPP/EPB setting coming from the ``sysfs`` interface

(see `Energy vs Performance Hints`_ below).

(see `Energy vs Performance Hints`_ below).  Moreover, any attempts to change

the EPP/EPB to a value different from 0 ("performance") via ``sysfs`` in this

configuration will be rejected.

Also, in this configuration the range of P-states available to the processor's

internal P-state selection logic is always restricted to the upper boundary

Energy-Performance Bias (EPB) knob. It is also possible to write a positive

integer value between 0 to 255, if the EPP feature is present. If the EPP

feature is not present, writing integer value to this attribute is not

supported. In this case, user can use

supported. In this case, user can use the

"/sys/devices/system/cpu/cpu*/power/energy_perf_bias" interface.
