[CPUFREQ][6/6] cpufreq: Add idle microaccounting in ondemand governor Use get_cpu_idle_time_us() to get micro-accounted idle information. This enables ondemand to get more accurate idle and busy timings than the jiffy based calculation. As a result, we can decrease the ondemand safety gaurd band from 80-10 to 95-3. Results in more aggressive power savings. Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Dave Jones <davej@redhat.com>
