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 - 1.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 1.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 1.90 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 9 Available idle states: POLL C1-HSW C1E-HSW C3-HSW C6-HSW C7s-HSW C8-HSW C9-HSW C10-HSW POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1314 Duration: 520405 C1-HSW: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 239015 Duration: 53720646 C1E-HSW: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 290581 Duration: 97252842 C3-HSW: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 311214 Duration: 152471024 C6-HSW: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 123751 Duration: 92586161 C7s-HSW: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 407468 Duration: 450395689 C8-HSW: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 543526 Duration: 915481337 C9-HSW: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 893265 Duration: 2786103738 C10-HSW: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 81695 Duration: 1541194205
