KMDF implements "self-managed I/O" callbacks ( EvtDeviceSelfManagedIoInit , EvtDeviceSelfManagedIoSuspend , EvtDeviceSelfManagedIoRestart ). These run only when the device is fully powered and started. You put your hardware access logic there. The framework handles D0/D3 transitions, idle detection, and wake signals.
KMDF provides a unified interface for communicating with other drivers or hardware, known as "I/O Targets." kernel-mode driver framework
