frequency-info -------------- analyzing CPU 3: driver: intel_cpufreq CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 maximum transition latency: 20.0 us hardware limits: 800 MHz - 2.50 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 2.50 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.40 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 Usage: 714 Duration: 17445 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 7826 Duration: 700954 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 11584 Duration: 1860891 C6: Flags/Description: MWAIT 0x20 Latency: 150 Usage: 0 Duration: 0 C7s: Flags/Description: MWAIT 0x31 Latency: 150 Usage: 54253 Duration: 39251738 C8: Flags/Description: MWAIT 0x40 Latency: 5963 Usage: 493 Duration: 412077 C9: Flags/Description: MWAIT 0x50 Latency: 5963 Usage: 1468 Duration: 2647324 C10: Flags/Description: MWAIT 0x60 Latency: 6291 Usage: 20036 Duration: 138184010
