frequency-info -------------- analyzing CPU 1: driver: intel_pstate CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: Cannot determine or is not supported. hardware limits: 700 MHz - 3.40 GHz available cpufreq governors: performance powersave current policy: frequency should be within 700 MHz and 3.40 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.36 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: Number of idle states: 5 Available idle states: POLL C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 23788 Duration: 513633 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Residency: 4 Usage: 593876 Duration: 164920802 C6: Flags/Description: MWAIT 0x20 Latency: 195 Residency: 585 Usage: 357158 Duration: 328251398 C8: Flags/Description: MWAIT 0x40 Latency: 260 Residency: 1040 Usage: 120598 Duration: 164036135 C10: Flags/Description: MWAIT 0x60 Latency: 660 Residency: 1980 Usage: 198594 Duration: 794260870
