frequency-info -------------- analyzing CPU 9: driver: intel_pstate CPUs which run at the same hardware frequency: 9 CPUs which need to have their frequency coordinated by software: 9 energy performance preference: balance_performance hardware limits: 800 MHz - 4.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 4.02 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 8: 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: 6983 Duration: 319126 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 1 Usage: 118654 Duration: 13977180 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x21 Latency: 127 Residency: 381 Usage: 86257 Duration: 54949990 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1048 Residency: 3144 Usage: 78752 Duration: 340482187
