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: 0.97 ms. hardware limits: 500 MHz - 2.42 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 500 MHz and 2.42 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 1.28 GHz (asserted by call to hardware). 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: 2252 Duration: 1252681 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 10552500 Duration: 55115900 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x51 Latency: 500 Usage: 400 Duration: 1328971 C3: Flags/Description: ACPI FFH INTEL MWAIT 0x52 Latency: 1500 Usage: 179 Duration: 1175442
