Resources are not dynamically configurable for legacy devices, so the PnP manager assigns resources to legacy devices first.Ī programming interface for drivers to interact with the PnP system The PnP manager retrieves the requirements for each device during resource allocation. The PnP manager reconfigures resource assignments when necessary, such as when a new device is added to the system that requires resources already in use.ĭrivers for PnP devices do not assign resources instead, the requested resources for a device are identified when the device is enumerated. The PnP manager determines the hardware resources requested by each device (for example, input/output ports, interrupt requests, direct memory access channels, and memory locations) and assigns hardware resources appropriately. Hardware resource allocation (and reallocation) The system software support for PnP, together with PnP drivers provides the following:Īutomatic and dynamic recognition of installed hardware
This Windows Driver Kit (WDK) documentation focuses on the system software support for PnP and how drivers use that support to implement PnP. Initiatives in the hardware industry define standards for easy identification of add-in boards and system components. PnP requires support from device hardware, system software, and drivers. For example, a user can dock a portable computer and use the docking station keyboard, mouse, and monitor without making manual configuration changes. A user can add and remove devices without having to do manual configuration, and without knowledge of computer hardware. Plug and Play (PnP) is the part of Windows that enables a computer system to adapt to hardware changes with minimal intervention by the user.
