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: yes Boost States: 2 Total States: 7 Pstate-Pb0: 4000MHz (boost state) Pstate-Pb1: 3700MHz (boost state) Pstate-P0: 3500MHz Pstate-P1: 2900MHz Pstate-P2: 2300MHz Pstate-P3: 1700MHz Pstate-P4: 1400MHz 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: 28024 Duration: 8162131 C2: Flags/Description: ACPI IOPORT 0x815 Latency: 100 Usage: 20654 Duration: 109104151
