Abstract
A system and method for delivering data from a device driver to an application increases the usage of synchronous processing (fast I/O mode) of data requests from the application by utilizing thread scheduling to enhance the likelihood that the requested data are available for immediate delivery to the application. If the amount of data in a data queue for storing data ready for delivery is low, the thread scheduling of the system is modified to promote the thread of the device driver to give it the opportunity to place more data in the data queue for consumption by the application. The promotion of the thread of the device driver may be done by switching from the application thread to another thread (not necessarily the device driver thread), boosting the device driver's priority, and/or lowering the priority of the application, etc.
