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.
