The governor "powersave" may decide which speed to use within this range. current CPU frequency: 4.80 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 9: 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: 1046 Duration: 55325 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 1 Usage: 29840 Duration: 4716692 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x30 Latency: 120 Residency: 360 Usage: 34421 Duration: 24352911 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x60 Latency: 1034 Residency: 3102 Usage: 40289 Duration: 374483107
