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 - 3.00 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.00 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 2.61 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 2800 MHz max turbo 4 active cores 2800 MHz max turbo 3 active cores 2800 MHz max turbo 2 active cores 3000 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 6 Available idle states: POLL C1-IVB C1E-IVB C3-IVB C6-IVB C7-IVB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1517 Duration: 1194001 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 66469 Duration: 18229123 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 103118 Duration: 40590412 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 47432 Duration: 24691099 C6-IVB: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 3043 Duration: 6436188 C7-IVB: Flags/Description: MWAIT 0x30 Latency: 87 Usage: 298171 Duration: 887117392
