Detailed Description

the driver: one per driver binary, holding and answering what is driver-wide

Every platform's driver form derives from it - WDM's platform::driver and the PortCls adapter on it, KMDF's driver, the DriverKit and IOKit shells' driver - and every device of the driver reaches it (dxd::device::driver). Its own client answers an open of the driver itself, where the platform offers one.
