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: 1.30 GHz - 2.30 GHz available frequency steps: 2.30 GHz, 2.10 GHz, 1.90 GHz, 1.70 GHz, 1.50 GHz, 1.30 GHz available cpufreq governors: performance schedutil current policy: frequency should be within 1.30 GHz and 2.30 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 2.30 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes Boost States: 2 Total States: 8 Pstate-Pb0: 2600MHz (boost state) Pstate-Pb1: 2500MHz (boost state) Pstate-P0: 2300MHz Pstate-P1: 2100MHz Pstate-P2: 1900MHz Pstate-P3: 1700MHz Pstate-P4: 1500MHz Pstate-P5: 1300MHz 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: ACPI HLT Latency: 0 Usage: 607020 Duration: 140372568 C2: Flags/Description: ACPI IOPORT 0x814 Latency: 400 Usage: 359981 Duration: 852256340
