frequency-info -------------- analyzing CPU 12: driver: intel_pstate CPUs which run at the same hardware frequency: 12 CPUs which need to have their frequency coordinated by software: 12 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 800 MHz and 4.80 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 4.49 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 9: 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: 197429 Duration: 10717148 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 1077513 Duration: 387755676 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x31 Latency: 253 Usage: 596771 Duration: 519892081 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1048 Usage: 2159974 Duration: 23689213257
