frequency-info -------------- analyzing CPU 6: driver: intel_pstate CPUs which run at the same hardware frequency: 6 CPUs which need to have their frequency coordinated by software: 6 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 4.20 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.20 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 800 MHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 7: Number of idle states: 7 Available idle states: POLL C1 C1E C3 C6 C7s C8 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1540869 Duration: 10457004 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 4413625 Duration: 312290471 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 2586093 Duration: 276341885 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 1486048 Duration: 227800347 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 3042066 Duration: 954157303 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 9167 Duration: 8110953 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 1875741 Duration: 2257780111
