frequency-info -------------- analyzing CPU 0: driver: intel_cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 20.0 us hardware limits: 1.60 GHz - 3.90 GHz available cpufreq governors: conservative userspace powersave ondemand performance current policy: frequency should be within 1.60 GHz and 3.90 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.90 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 3900 MHz max turbo 4 active cores 3900 MHz max turbo 3 active cores 3900 MHz max turbo 2 active cores 3900 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-IVB C1E-IVB C3-IVB C6-IVB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 40 Duration: 3579 C1-IVB: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 8970 Duration: 657230 C1E-IVB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 11566 Duration: 1954238 C3-IVB: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 4622 Duration: 1321363 C6-IVB: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 61141 Duration: 582571807
