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: 1.20 GHz - 3.10 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.20 GHz and 3.10 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: 2.52 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: 5 Available idle states: POLL C1-BDW C1E-BDW C3-BDW C6-BDW POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1599705 Duration: 571794119 C1-BDW: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 48031877 Duration: 1932901237 C1E-BDW: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 192998905 Duration: 16035978872 C3-BDW: Flags/Description: MWAIT 0x10 Latency: 40 Usage: 452788094 Duration: 138644494627 C6-BDW: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 491063035 Duration: 549717840183
