From 9e21ba8bd849251c8ba22ddf39308a5227134fdc Mon Sep 17 00:00:00 2001 From: Dirk Brandewie Date: Wed, 6 Feb 2013 09:02:08 -0800 Subject: [PATCH] cpufreq: Retrieve current frequency from scaling drivers with internal governors Scaling drivers that implement the cpufreq_driver.setpolicy() versus the cpufreq_driver.target() interface do not set policy->cur. Normally policy->cur is set during the call to cpufreq_driver.target() when the frequnecy request is made by the governor. If the scaling driver implements cpufreq_driver.setpolicy() and cpufreq_driver.get() interfaces use cpufreq_driver.get() to retrieve the current frequency.
