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 - 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: 1.56 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 6308 Duration: 52992 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 198510 Duration: 57928165 C2: Flags/Description: ACPI FFH MWAIT 0x31 Latency: 253 Usage: 45478 Duration: 37287184 C3: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1048 Usage: 213537 Duration: 453287450
