frequency-info -------------- analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us. hardware limits: 1.20 GHz - 2.30 GHz available frequency steps: 2.30 GHz, 1.60 GHz, 1.20 GHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 1.20 GHz and 2.30 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 2.30 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: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 209 Duration: 90733 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 16171 Duration: 2612050 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x10 Latency: 1 Usage: 64309 Duration: 23890510 C3: Flags/Description: ACPI FFH INTEL MWAIT 0x20 Latency: 17 Usage: 326464 Duration: 720205596
