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: 1.40 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: yes 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: 78001 Duration: 3380910 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 26509463 Duration: 9070050666 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 350 Usage: 3139207 Duration: 2615675965 C3: Flags/Description: ACPI IOPORT 0x415 Latency: 400 Usage: 15739577 Duration: 42224255440
