WebActive Mode¶. This is the default operation mode of intel_pstate.If it works in this mode, the scaling_driver policy attribute in sysfs for all CPUFreq policies contains the string “intel_pstate”.. In this mode the driver bypasses the scaling governors layer of CPUFreq and provides its own scaling algorithms for P-state selection. Those algorithms can be … WebSince the CPU is running slower, this makes tasks take longer to complete, and this can actually cause you to use more power overall, since it's forced to stay longer in a non-idle state to complete the same work. You want it to be idle as much as possible, since that's the lowest power option.
