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: 500 MHz - 1.83 GHz available cpufreq governors: performance powersave current policy: frequency should be within 500 MHz and 1.83 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.23 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 6 Available idle states: POLL C1 C6N C6S C7 C7S POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 2069 Duration: 117828 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 188264 Duration: 27882406 C6N: Flags/Description: MWAIT 0x58 Latency: 300 Usage: 88441 Duration: 51824410 C6S: Flags/Description: MWAIT 0x52 Latency: 500 Usage: 62871 Duration: 48635631 C7: Flags/Description: MWAIT 0x60 Latency: 1200 Usage: 79733 Duration: 113516197 C7S: Flags/Description: MWAIT 0x64 Latency: 10000 Usage: 9387 Duration: 26978595
