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: 800 MHz - 2.40 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 2.40 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.05 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: 406964 Duration: 6183207 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 2378614 Duration: 4864681550 C2: Flags/Description: ACPI IOPORT 0x415 Latency: 50 Usage: 194701 Duration: 3832840 C3: Flags/Description: ACPI IOPORT 0x419 Latency: 150 Usage: 2917050283 Duration: 8547380079
