Subject: [PATCH] Documentation/admin-guide/pm/intel_pstate: fix Active Mode w/o HWP paragraph
Date: Tue, 8 May 2018 17:12:09 +0200 [thread overview]
Message-ID: <20180508151209.9314-1-juri.lelli@redhat.com> (raw)
P-state selection algorithm (powersave or performance) is selected by
echoing the desired choice to scaling_governor sysfs attribute and not
to scaling_cur_freq (as currently stated).
Fix it.

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_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.
