The governor "powersave" may decide which speed to use within this range. current CPU frequency: 3.40 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 19: Number of idle states: 4 Available idle states: POLL C1_ACPI C2_ACPI C3_ACPI POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 862357 Duration: 26008446 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 1 Usage: 114032243 Duration: 16665541462 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x21 Latency: 127 Residency: 381 Usage: 102079172 Duration: 56822283559 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1048 Residency: 3144 Usage: 87465422 Duration: 396680158848
