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: 1.99 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: 2065 Duration: 18590 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 33209 Duration: 10312360 C2: Flags/Description: ACPI FFH MWAIT 0x31 Latency: 253 Usage: 15010 Duration: 22672083 C3: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1048 Usage: 28824 Duration: 1079543706
