frequency-info -------------- analyzing CPU 4: driver: intel_pstate CPUs which run at the same hardware frequency: 4 CPUs which need to have their frequency coordinated by software: 4 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 4.10 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.10 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.92 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 5: Number of idle states: 3 Available idle states: POLL C1 C2 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1334 Duration: 36131 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 36071 Duration: 6043671 C2: Flags/Description: ACPI FFH MWAIT 0x10 Latency: 79 Usage: 432117 Duration: 9939954106
