The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 1000 MHz (asserted by call to hardware) idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 4: Number of idle states: 6 Available idle states: POLL C1 C2 C3 C4 C5 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 11621 Duration: 476519 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 699571 Duration: 74431574 C2: Flags/Description: ACPI IOPORT 0x814 Latency: 50 Usage: 164058 Duration: 33752662 C3: Flags/Description: ACPI IOPORT 0x816 Latency: 60 Usage: 83681 Duration: 19052935 C4: Flags/Description: ACPI IOPORT 0x817 Latency: 70 Usage: 1351704 Duration: 498838702 C5: Flags/Description: ACPI IOPORT 0x818 Latency: 270 Usage: 2970096 Duration: 3730402031
