In this mode ``intel_pstate`` registers utilization update callbacks with the

CPU scheduler in order to run a P-state selection algorithm, either

``powersave`` or ``performance``, depending on the ``scaling_cur_freq`` policy

``powersave`` or ``performance``, depending on the ``scaling_governor`` policy

setting in ``sysfs``.  The current CPU frequency information to be made

available from the ``scaling_cur_freq`` policy attribute in ``sysfs`` is

periodically updated by those utilization update callbacks too.
