Abstract
Techniques for intercommunication amongst device drivers are described herein. In one embodiment, an application programming interface (API) is provided by a kernel of an operating system (OS) running within a data processing system. The API is accessible by device drivers associated with multiple devices installed in the system. In response to a request from a first instance of a driver the API, information indicating whether another instance of the same driver is currently started is returned via the API. Other methods and apparatuses are also described.
