frequency-info -------------- analyzing CPU 2: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 maximum transition latency: Cannot determine or is not supported. hardware limits: 1.40 GHz - 2.90 GHz available frequency steps: 2.90 GHz, 1.70 GHz, 1.40 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.40 GHz and 2.90 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: 2.90 GHz (asserted by call to hardware) boost state support: Supported: yes Active: no Boost States: 0 Total States: 3 Pstate-P0: 2900MHz Pstate-P1: 1700MHz Pstate-P2: 1400MHz 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: 90118 Duration: 9989412 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 19002332 Duration: 5526695425 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 350 Usage: 1033437 Duration: 931348736 C3: Flags/Description: ACPI IOPORT 0x415 Latency: 400 Usage: 19648373 Duration: 44523386604
