frequency-info -------------- analyzing CPU 2: driver: intel_cpufreq CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 maximum transition latency: 20.0 us hardware limits: 800 MHz - 4.50 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 4.50 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 4.39 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 4: Number of idle states: 3 Available idle states: POLL C1_ACPI C2_ACPI POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 747 Duration: 81423 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 33248 Duration: 7878824 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x10 Latency: 79 Usage: 94338 Duration: 169208122
