frequency-info -------------- analyzing CPU 6: driver: intel_pstate CPUs which run at the same hardware frequency: 6 CPUs which need to have their frequency coordinated by software: 6 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 4.50 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.50 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 4.30 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: 3810 Duration: 147193 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 272433 Duration: 64195660 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x33 Latency: 151 Usage: 175475 Duration: 164557715 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1034 Usage: 258878 Duration: 2324397440
