tools/power turbostat: Build-in "Low Power Idle" counters support Linux 4.15 exports the ACPI Low Power Idle Table's counters in /sys/devices/system/cpu/cpuidle/ low_power_idle_cpu_residency_us Show this in the "CPU%LPI" column. Today this reflects the "North Complex" residency in PC10, so expect it to closely follow "Pk%pc10". low_power_idle_system_residency_us Show this in the "SYS%LPI" column. Today, this reflects the North is in PC10, plus the PCH is sufficiently quiescent to save additional power via the "S0ix" system state, as measured by the PCH SLP_S0 counter.
