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: 400 MHz - 4.70 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.70 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.40 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: 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: 417605 Duration: 7729062 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 1 Usage: 9588263 Duration: 1324041954 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x21 Latency: 127 Residency: 381 Usage: 5638332 Duration: 3299341344 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1048 Residency: 3144 Usage: 5573291 Duration: 16605728859
