Abstract

A configuration adaptation layer (CAL) for I/O devices such as I/O adapters is provided. This configuration adaptation layer (CAL) explicitly provides a mapping between adapter functions and adapter resources in a way such that it is senseable in-band by the computer system using the adapter, e.g., by a virtual machine monitor.
