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 - 4.00 GHz available frequency steps: 4.00 GHz, 3.40 GHz, 2.80 GHz, 2.10 GHz, 1.40 GHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 1.40 GHz and 4.00 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 1.40 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes Boost States: 2 Total States: 7 Pstate-Pb0: 4200MHz (boost state) Pstate-Pb1: 4100MHz (boost state) Pstate-P0: 4000MHz Pstate-P1: 3400MHz Pstate-P2: 2800MHz Pstate-P3: 2100MHz Pstate-P4: 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: 66539 Duration: 59963899 C2: Flags/Description: ACPI IOPORT 0x815 Latency: 100 Usage: 106367 Duration: 516387562
