Advanced Power Management for KMDF Drivers
As the examples in the previous section show, the framework handles most of the work in implementing Plug and Play and power management, even for a driver that supports a hardware device. This section describes how to go beyond the basics to add support for two advanced KMDF features:
Device idle support
