The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.70 GHz (asserted by call to hardware) boost state support: Supported: yes Active: no idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 3 Available idle states: POLL C1 C2 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 0 Duration: 0 C1: Flags/Description: <null> Latency: 0 Usage: 99279 Duration: 58970805 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 400 Usage: 54344 Duration: 375655979
