frequency-info -------------- analyzing CPU 1: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: 10.0 us hardware limits: 1.60 GHz - 2.26 GHz available frequency steps: 2.26 GHz, 2.13 GHz, 1.86 GHz, 1.60 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.60 GHz and 2.26 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.26 GHz (asserted by call to kernel) boost state support: Supported: no Active: no idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 1: Number of idle states: 4 Available idle states: POLL C1_ACPI C2_ACPI C3_ACPI POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 538 Duration: 23472 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 1 Usage: 857 Duration: 22028 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x10 Latency: 1 Residency: 3 Usage: 286220 Duration: 26603382 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x31 Latency: 57 Residency: 171 Usage: 328240 Duration: 287110443
