From mboxrd@z Thu Jan 1 00:00:00 1970 From: Antti P Miettinen Subject: [PATCH] cpufreq: Export user_policy min/max Date: Thu, 19 Jan 2012 14:51:01 +0200 Message-ID: <1326977461-4348-1-git-send-email-amiettinen@nvidia.com> Return-path: Sender: cpufreq-owner@vger.kernel.org To: davej@redhat.com, pavel@ucw.cz, rjw@sisk.pl, len.brown@intel.com, khilman@ti.com, j-pihet@ti.com, markgross@thegnar.org, cpufreq@vger.kernel.org, linux-pm@lists.linux-foundation.org List-Id: linux-pm@vger.kernel.org Add read-only sysfs nodes for user_policy min and max settings. This helps diagnosis in the presence of other constraints that affect the currently enforced policy minimum and maximum that can be viewed with scaling_{min,max}_freq.
