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: 0.97 ms. hardware limits: 800 MHz - 1.50 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 800 MHz and 1.50 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 1.39 GHz (asserted by call to hardware). boost state support: Supported: no Active: no 25500 MHz max turbo 4 active cores 25500 MHz max turbo 3 active cores 25500 MHz max turbo 2 active cores 25500 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu Analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1-SNB C1E-SNB C3-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 3252 Duration: 413913 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 1073031 Duration: 136396781 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 1440974 Duration: 337467244 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 1157150 Duration: 1357586476
