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: 1000 MHz - 2.00 GHz available frequency steps: 2.00 GHz, 1.80 GHz, 1.60 GHz, 1.40 GHz, 1.20 GHz, 1000 MHz available cpufreq governors: conservative userspace powersave ondemand performance schedutil current policy: frequency should be within 1000 MHz and 2.00 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: 2.00 GHz (asserted by call to hardware) boost state support: Supported: yes Active: no Boost States: 2 Total States: 8 Pstate-Pb0: 2400MHz (boost state) Pstate-Pb1: 2200MHz (boost state) Pstate-P0: 2000MHz Pstate-P1: 1800MHz Pstate-P2: 1600MHz Pstate-P3: 1400MHz Pstate-P4: 1200MHz Pstate-P5: 1000MHz 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: 57910 Duration: 32903755 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 400 Usage: 50960 Duration: 160366834
