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 - 4.70 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.70 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 4.28 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: 9 Available idle states: POLL C1 C1E C3 C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 61116163 Duration: 368526211 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 300007990 Duration: 32005346086 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 324086206 Duration: 37910136516 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 265858041 Duration: 32963938723 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 614400296 Duration: 165608528506 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 587429 Duration: 250259108 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 450716865 Duration: 266280772913 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 6811954 Duration: 4038439619 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 125778921 Duration: 95406992292
