frequency-info -------------- analyzing CPU 1: driver: intel_cpufreq CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: 20.0 us hardware limits: 800 MHz - 2.80 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 2.80 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.49 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: 8 Available idle states: POLL C1 C1E C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 5460 Duration: 76006 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 7011 Duration: 453489 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 10346 Duration: 1121818 C6: Flags/Description: MWAIT 0x20 Latency: 150 Residency: 150 Usage: 0 Duration: 0 C7s: Flags/Description: MWAIT 0x31 Latency: 150 Residency: 150 Usage: 29720 Duration: 17274738 C8: Flags/Description: MWAIT 0x40 Latency: 5963 Residency: 5963 Usage: 80 Duration: 87009 C9: Flags/Description: MWAIT 0x50 Latency: 5963 Residency: 5963 Usage: 1127 Duration: 2258086 C10: Flags/Description: MWAIT 0x60 Latency: 6291 Residency: 6291 Usage: 14711 Duration: 35491757
