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 - 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 is 1.10 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 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: 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: 1570 Duration: 3158006 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 219835 Duration: 27482596 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 861704 Duration: 210062440 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 220300 Duration: 114409147 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 1997 Duration: 2841805 C7-SNB: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 3171593 Duration: 10033147100
