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 - 2.40 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 2.40 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 1.83 GHz (asserted by call to hardware) boost state support: Supported: no Active: no 2400 MHz max turbo 4 active cores 2400 MHz max turbo 3 active cores 2400 MHz max turbo 2 active cores 2400 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-SNB C1E-SNB C3-SNB C6-SNB C7-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 505 Duration: 283638 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 34404 Duration: 13757456 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 68735 Duration: 48420068 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 19103 Duration: 10226817 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 328 Duration: 378886 C7-SNB: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 285017 Duration: 933627824
