frequency-info -------------- analyzing CPU 15: driver: intel_pstate CPUs which run at the same hardware frequency: 15 CPUs which need to have their frequency coordinated by software: 15 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 3.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.60 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 12: Number of idle states: 4 Available idle states: POLL C1_ACPI C2_ACPI C3_ACPI POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 5893 Duration: 213044 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 136227 Duration: 24106645 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x21 Latency: 127 Usage: 150025 Duration: 98272908 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1048 Usage: 174176 Duration: 1469208377
