frequency-info -------------- analyzing CPU 0: driver: intel_pstate 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: 480 MHz - 2.48 GHz available cpufreq governors: performance powersave current policy: frequency should be within 480 MHz and 2.48 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 963 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: 6 Available idle states: POLL C1 C6N C6S C7 C7S POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 213 Duration: 50443 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 31910 Duration: 14704558 C6N: Flags/Description: MWAIT 0x58 Latency: 80 Usage: 6480 Duration: 6161377 C6S: Flags/Description: MWAIT 0x52 Latency: 200 Usage: 15609 Duration: 38693535 C7: Flags/Description: MWAIT 0x60 Latency: 1200 Usage: 7818 Duration: 55337236 C7S: Flags/Description: MWAIT 0x64 Latency: 10000 Usage: 1200 Duration: 107577306
