frequency-info -------------- analyzing CPU 7: driver: intel_pstate CPUs which run at the same hardware frequency: 7 CPUs which need to have their frequency coordinated by software: 7 energy performance preference: balance_performance hardware limits: 400 MHz - 3.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 3.13 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 4: Number of idle states: 4 Available idle states: POLL C1_ACPI C2_ACPI C3_ACPI POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 928 Duration: 46013 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 1 Usage: 155330 Duration: 37190914 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x31 Latency: 253 Residency: 759 Usage: 30933 Duration: 25009647 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1048 Residency: 3144 Usage: 70929 Duration: 480681956
