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: Cannot determine or is not supported. hardware limits: 1.55 GHz - 3.20 GHz available frequency steps: 3.20 GHz, 2.80 GHz, 1.55 GHz available cpufreq governors: performance schedutil current policy: frequency should be within 1.55 GHz and 3.20 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 1.55 GHz (asserted by call to hardware) boost state support: Supported: no Active: no Boost States: 0 Total States: 3 Pstate-P0: 3200MHz Pstate-P1: 2800MHz Pstate-P2: 1550MHz 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: 24860 Duration: 95673 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 3632345 Duration: 1032102857 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 400 Usage: 3206650 Duration: 8030941333
