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: 800 MHz - 3.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.60 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.34 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 7 Available idle states: POLL C1 C1E C3 C6 C7s C8 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 283247 Duration: 2302638 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 646351 Duration: 52895842 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 1498879 Duration: 214265143 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 535480 Duration: 93872859 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 1396680 Duration: 638207781 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 14867 Duration: 19645125 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 850117 Duration: 1539805548
