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: 400 MHz - 2.30 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 2.30 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 857 MHz (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: 9 Available idle states: POLL C1 C1E C3 C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 109123 Duration: 682281 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 59454 Duration: 4779380 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 74122 Duration: 32384536 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 55 Duration: 32290 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 26092 Duration: 16630105 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 4507 Duration: 6679034 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 45833 Duration: 87992017 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 196 Duration: 186552 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 16905 Duration: 238444002
