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: 1.60 GHz - 4.39 GHz available frequency steps: 2.30 GHz, 1.80 GHz, 1.60 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.60 GHz and 2.30 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.60 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes Boost States: 0 Total States: 3 Pstate-P0: 2300MHz Pstate-P1: 1800MHz Pstate-P2: 1600MHz idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1061 Duration: 22989 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 66639 Duration: 16106809 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 18 Usage: 37353 Duration: 16680623 C3: Flags/Description: ACPI IOPORT 0x415 Latency: 350 Usage: 123080 Duration: 1475053179
