System and method of supporting virtual mappings for shared firmware contents in a computer system are described. In one embodiment, the method comprises, responsive to a function call issued by a processor, determining whether address translation has been enabled for the issuing processor; and responsive to a determination that address translation has been enabled, determining an ID of the issuing processor; identifying a Physical-to-Virtual ("PTV") Map corresponding to the issuing processor; extracting from the identified PTV map a virtual address corresponding to a physical address passed in the function call; and returning the virtual address to the issuing processor.
