frequency-info -------------- analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 1.20 GHz - 4.70 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.20 GHz and 4.70 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.30 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: Number of idle states: 4 Available idle states: POLL C1 C1E C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 82043 Duration: 219789 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 6144 Duration: 1646592 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 2141 Duration: 412671 C6: Flags/Description: MWAIT 0x20 Latency: 92 Usage: 32273 Duration: 408366849
