Example

pwr := intelpower.New()

if err := pwr.CheckDriver(); err != nil {
	panic(err)
}

stat, _ := pwr.GetStatus()
switch stat {
case PStateStatusActive:
	fmt.Println("All is ok")
case PStateStatusPassive:
	fmt.Println("Some troubles, some actions maybe ignored")
case PStateStatusOff:
	fmt.Println("Driver is off, actions won't take effects")
}

// CPU name
cpuName, _ := pwr.GetCPUName()

// temperature from main thermal sensor
temp, _ := pwr.GetTemp()

// TurboBoost checking and enabling
if turbo, _ := pwr.IsTurbo(); !turbo {
	pwr.SetTurbo(true)
}

// Always maximum frequency
_ := pwr.GetMinPerf(1)

// Working with CPUs
cpus, _ := pwr.GetCPUs()

// CPU frequency
freq, _ := cpus[0].GetFreq()
baseFreq, _ := cpus[0].GetBaseFreq()
maxFreq, _ := cpus[0].GetMaxFreq()
minFreq, _ := cpus[0].GetMinFreq()

// CPU disabling
cpus[3].SetOnline(false)

// CPU governor mode
cpus[3].SetGovernor(CPUGovernorPerformance)

// CPU preference mode
cpus[3].SetPreference(CPUPreferencePerformance)
