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: 2.20 GHz - 4.56 GHz available frequency steps: 3.90 GHz, 2.80 GHz, 2.20 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 2.20 GHz and 3.90 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 3.90 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes Boost States: 0 Total States: 3 Pstate-P0: 3900MHz Pstate-P1: 2800MHz Pstate-P2: 2200MHz 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: 1145112 Duration: 13761292 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 70907167 Duration: 17106717936 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 400 Usage: 37890786 Duration: 151249696310
