frequency-info -------------- analyzing CPU 3: driver: intel_pstate CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 energy performance preference: balance_performance hardware limits: 800 MHz - 5.10 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 5.10 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 3.40 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: 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: 259313 Duration: 15616633 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 1 Usage: 77923 Duration: 12425733 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x33 Latency: 151 Residency: 453 Usage: 51825 Duration: 34183957 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1034 Residency: 3102 Usage: 89145 Duration: 345176409
