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: 500 MHz - 2.67 GHz available cpufreq governors: ondemand userspace performance schedutil current policy: frequency should be within 500 MHz and 2.67 GHz. The governor "userspace" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.17 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 3: Number of idle states: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 2892749 Duration: 169427822 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 144537066 Duration: 19260766984 C2: Flags/Description: ACPI FFH MWAIT 0x51 Latency: 500 Usage: 5692792 Duration: 8751438026 C3: Flags/Description: ACPI FFH MWAIT 0x52 Latency: 1500 Usage: 6816781 Duration: 73661183646
