frequency-info -------------- analyzing CPU 13: driver: intel_pstate CPUs which run at the same hardware frequency: 13 CPUs which need to have their frequency coordinated by software: 13 energy performance preference: balance_power hardware limits: 400 MHz - 4.00 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.00 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 2.00 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 13: Number of idle states: 4 Available idle states: POLL C1_ACPI C2_ACPI C3_ACPI POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 1114 Duration: 73943 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 1 Usage: 103479 Duration: 16533600 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x21 Latency: 127 Residency: 381 Usage: 29119 Duration: 15988340 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1048 Residency: 3144 Usage: 352546 Duration: 898707136
