Abstract
A vendor-independent resource configuration interface automatically maps virtual functions to physical functions in a self-virtualizing IO resource using the concept of a logical port that maps to a particular physical port and protocol in the self-virtualizing IO resource. A user wishing to provide a logical partition access to a self-virtualizing IO resource typically creates or configures a logical port for the logical partition by mapping the logical port to a particular physical port and protocol defined for the self-virtualizing IO resource, and an appropriate virtual function mapped to an appropriate physical function on an appropriate self-virtualizing IO resource is automatically selected, typically without requiring the user to have a detailed understanding of the numbers of supported virtual functions, physical functions and protocols supported by specific resources.
