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 - 2.10 GHz available frequency steps: 2.10 GHz, 1.60 GHz, 1.20 GHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 1.20 GHz and 2.10 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 2.10 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: 3 Available idle states: POLL C1 C2 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 71421 Duration: 1557422 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 92539478 Duration: 2024200047 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x20 Latency: 17 Usage: 25054917 Duration: 41712659230
