frequency-info -------------- analyzing CPU 6: driver: intel_pstate CPUs which run at the same hardware frequency: 6 CPUs which need to have their frequency coordinated by software: 6 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 3.50 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.50 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.80 GHz (asserted by call to kernel) 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 C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 3549 Duration: 137537 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Usage: 63755 Duration: 10694666 C6: Flags/Description: MWAIT 0x20 Latency: 170 Usage: 7775 Duration: 5103462 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 13747 Duration: 10851645 C10: Flags/Description: MWAIT 0x60 Latency: 230 Usage: 184393 Duration: 859996070
