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 - 3.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.38 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 Residency: 0 Usage: 2653 Duration: 43805 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 13203 Duration: 1443017 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 16857 Duration: 2471519 C3: Flags/Description: MWAIT 0x10 Latency: 70 Residency: 100 Usage: 6113 Duration: 1020290 C6: Flags/Description: MWAIT 0x20 Latency: 85 Residency: 200 Usage: 27896 Duration: 15460061 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Residency: 800 Usage: 96 Duration: 69212 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 800 Usage: 23961 Duration: 448640151
