frequency-info -------------- analyzing CPU 6: driver: intel_pstate CPUs which run at the same hardware frequency: 6 CPUs which need to have their frequency coordinated by software: 6 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 4.20 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.20 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 4.00 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 5: 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: 159087 Duration: 362940 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 33603 Duration: 2504323 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 7393 Duration: 1113768 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 3001 Duration: 448865 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 13401 Duration: 7507353 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 2 Duration: 1125 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 17045 Duration: 135950678
