The runpm parameter allows you to disable runtime power management which powers
down dGPUs at runtime if they are not being used (e.g., hybrid graphics laptops
or desktop systems with multiple GPUs) to save power.  It does not affect
dynamic power management while the chip is powered up.  Disabling it will
increase idle power usage.
