Abstract
Techniques and mechanisms for providing access to a function with an input/output (I/O) device. In an embodiment, a main memory of a computer system including the I/O device stores a function-context data structure associating a function with a context for an access to the function. The I/O device stores a configuration for the I/O device to provide the function. In another embodiment, the software process exchanges information with the function-context data structure for the access to the function. The I/O device performs a synchronization of the function-context data structure and the configuration data structure with respect to one another, wherein the function-context data structure operates as a register level interface which interfaces the I/O device and the software process with one another.
