frequency-info -------------- analyzing CPU 18: driver: intel_pstate CPUs which run at the same hardware frequency: 18 CPUs which need to have their frequency coordinated by software: 18 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 4.20 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.20 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.63 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 21: Number of idle states: 3 Available idle states: POLL C1_ACPI C2_ACPI POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 6050 Duration: 127120 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 294195 Duration: 56317996 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x21 Latency: 127 Usage: 1941571 Duration: 77137476910
