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 - 2.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 2.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 2.21 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 9 Available idle states: POLL C1-HSW C1E-HSW C3-HSW C6-HSW C7s-HSW C8-HSW C9-HSW C10-HSW POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1395 Duration: 1468801 C1-HSW: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 120036 Duration: 25835212 C1E-HSW: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 71657 Duration: 29932557 C3-HSW: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 145647 Duration: 72866316 C6-HSW: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 40861 Duration: 29144305 C7s-HSW: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 118331 Duration: 199926560 C8-HSW: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 68922 Duration: 136394895 C9-HSW: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 116076 Duration: 472751752 C10-HSW: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 45317 Duration: 889998061
