The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.60 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 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: 1308 Duration: 1584115 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 328032 Duration: 146972986 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x30 Latency: 57 Usage: 1026189 Duration: 836701921
