frequency-info -------------- analyzing CPU 0: driver: intel_cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 20.0 us hardware limits: 533 MHz - 1.47 GHz available cpufreq governors: performance schedutil current policy: frequency should be within 533 MHz and 1.47 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.47 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: 6 Available idle states: POLL C1 C6N C6S C7 C7S POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 240351 Duration: 1681831 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 1244230 Duration: 919690246 C6N: Flags/Description: MWAIT 0x58 Latency: 300 Usage: 499094 Duration: 474913801 C6S: Flags/Description: MWAIT 0x52 Latency: 500 Usage: 1804989 Duration: 3064734162 C7: Flags/Description: MWAIT 0x60 Latency: 1200 Usage: 1003465 Duration: 7971175401 C7S: Flags/Description: MWAIT 0x64 Latency: 10000 Usage: 43913 Duration: 1559915643
