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 - 3.60 GHz available frequency steps: 3.60 GHz, 3.20 GHz, 2.80 GHz, 2.40 GHz, 1.90 GHz, 1.40 GHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 1.40 GHz and 3.60 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 3.60 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes Boost States: 2 Total States: 8 Pstate-Pb0: 3800MHz (boost state) Pstate-Pb1: 3700MHz (boost state) Pstate-P0: 3600MHz Pstate-P1: 3200MHz Pstate-P2: 2800MHz Pstate-P3: 2400MHz Pstate-P4: 1900MHz Pstate-P5: 1400MHz 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: 488718 Duration: 346001956 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 100 Usage: 1723172 Duration: 5572079004
