The governor "performance" may decide which speed to use within this range. current CPU frequency: 2.20 GHz (asserted by call to hardware) boost state support: Supported: no 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: 516 Duration: 18633 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 198126 Duration: 86648599 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x20 Latency: 17 Usage: 6864599 Duration: 253788409
