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 - 3.00 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.00 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.11 GHz (asserted by call to kernel) boost state support: Supported: no Active: no idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 35243 Duration: 66482 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 28603 Duration: 6568680 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 52620 Duration: 8862535 C3: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 48566 Duration: 30910307 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 109058 Duration: 317575900
