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: 800 MHz - 3.20 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.20 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 859 MHz (asserted by call to kernel) boost state support: Supported: no Active: no 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: 18803 Duration: 1267124 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Usage: 178360 Duration: 40127128 C6: Flags/Description: MWAIT 0x20 Latency: 220 Usage: 31534 Duration: 19778603 C8: Flags/Description: MWAIT 0x40 Latency: 280 Usage: 31892 Duration: 19542531 C10: Flags/Description: MWAIT 0x60 Latency: 680 Usage: 259988 Duration: 1637531137
