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: 4.0 us. hardware limits: 1.40 GHz - 2.30 GHz available frequency steps: 2.30 GHz, 2.00 GHz, 1.80 GHz, 1.60 GHz, 1.40 GHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 1.40 GHz and 2.30 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 1.60 GHz (asserted by call to hardware). boost state support: Supported: yes Active: no Boost States: 2 Total States: 8 Pstate-Pb0: 3200MHz (boost state) Pstate-Pb1: 2700MHz (boost state) Pstate-P0: 2300MHz Pstate-P1: 2000MHz Pstate-P2: 1800MHz Pstate-P3: 1600MHz Pstate-P4: 1400MHz Pstate-P5: 900MHz 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: 0 Duration: 0 C1: Flags/Description: <null> Latency: 0 Usage: 47315 Duration: 45335313 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 100 Usage: 87759 Duration: 335613225
