frequency-info -------------- analyzing CPU 4: driver: intel_pstate CPUs which run at the same hardware frequency: 4 CPUs which need to have their frequency coordinated by software: 4 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 4.80 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1000 MHz and 3.25 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.03 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 6: Number of idle states: 4 Available idle states: POLL C1_ACPI C2_ACPI C3_ACPI POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 43220960 Duration: 112637774 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 60796289 Duration: 3995085314 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x31 Latency: 253 Usage: 4515880 Duration: 3950792663 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1048 Usage: 11719586 Duration: 184822267062
