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: 600 MHz - 1000 MHz available frequency steps: 1000 MHz, 900 MHz, 800 MHz, 700 MHz, 600 MHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 600 MHz and 1000 MHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 900 MHz (asserted by call to hardware). boost state support: Supported: yes Active: yes Boost States: 2 Total States: 7 Pstate-Pb0: 1400MHz (boost state) Pstate-Pb1: 1200MHz (boost state) Pstate-P0: 1000MHz Pstate-P1: 900MHz Pstate-P2: 800MHz Pstate-P3: 700MHz Pstate-P4: 600MHz 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: 525446 Duration: 246837505 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 400 Usage: 128477 Duration: 475274029
