The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.90 GHz (asserted by call to hardware) boost state support: Supported: no Active: no Boost States: 0 Total States: 4 Pstate-P0: 2900MHz Pstate-P1: 2200MHz Pstate-P2: 1700MHz Pstate-P3: 800MHz 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: 318213 Duration: 333575947
