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: 0.00 ms. hardware limits: 800 MHz - 2.70 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 800 MHz and 2.70 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 2.40 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu Analyzing CPU 0: Number of idle states: 9 Available idle states: POLL C1-HSW C1E-HSW C3-HSW C6-HSW C7s-HSW C8-HSW C9-HSW C10-HSW POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 320 Duration: 337911 C1-HSW: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 79038 Duration: 21736794 C1E-HSW: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 20164 Duration: 21331162 C3-HSW: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 20382 Duration: 14589419 C6-HSW: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 4974 Duration: 5192568 C7s-HSW: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 21970 Duration: 32359994 C8-HSW: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 21941 Duration: 46786383 C9-HSW: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 47568 Duration: 192728728 C10-HSW: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 16639 Duration: 291043702
