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_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.
