The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 3.20 GHz (asserted by call to hardware) boost state support: Supported: yes Active: no Boost States: 2 Total States: 8 Pstate-Pb0: 3700MHz (boost state) Pstate-Pb1: 3500MHz (boost state) Pstate-P0: 3200MHz Pstate-P1: 2900MHz Pstate-P2: 2600MHz Pstate-P3: 2200MHz Pstate-P4: 1800MHz Pstate-P5: 1400MHz idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 2 Available idle states: POLL C1 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 0 Duration: 0 C1: Flags/Description: ACPI HLT Latency: 0 Usage: 77632 Duration: 512264974
