frequency-info -------------- analyzing CPU 5: driver: amd-pstate-epp CPUs which run at the same hardware frequency: 5 CPUs which need to have their frequency coordinated by software: 5 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 3.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.87 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes Boost States: 0 Total States: 3 Pstate-P0: 2600MHz 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: 46599 Duration: 1357530 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 18426298 Duration: 5108976438 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 350 Usage: 3724276 Duration: 3397473782 C3: Flags/Description: ACPI IOPORT 0x415 Latency: 400 Usage: 9029716 Duration: 18840454635
