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: 1.60 GHz - 3.40 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.60 GHz and 3.40 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 2.63 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 3200 MHz max turbo 4 active cores 3300 MHz max turbo 3 active cores 3300 MHz max turbo 2 active cores 3400 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 5 Available idle states: POLL C1-SNB C1E-SNB C3-SNB C6-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 3710 Duration: 424945 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 10593 Duration: 3291927 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 25905 Duration: 16804740 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 5039 Duration: 3892354 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 34507 Duration: 108185197
