frequency-info -------------- analyzing CPU 9: driver: intel_pstate CPUs which run at the same hardware frequency: 9 CPUs which need to have their frequency coordinated by software: 9 energy performance preference: power hardware limits: 400 MHz - 900 MHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 900 MHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 900 MHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 5 Available idle states: POLL C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 25421 Duration: 882227 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Residency: 4 Usage: 558405 Duration: 132411286 C6: Flags/Description: MWAIT 0x20 Latency: 170 Residency: 500 Usage: 72450 Duration: 48528560 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 600 Usage: 166810 Duration: 135240084 C10: Flags/Description: MWAIT 0x60 Latency: 230 Residency: 700 Usage: 1406842 Duration: 8504622875
