Patent ID: 8176207

Claim:
A system, comprising: an interface core configured to connect a component of an information handling system device, the interface core comprising an electric circuit including one or more electronic components and control logic to interface with the information handling system device; a front end data channel coupled with the interface core configured to connect the electric circuit to the component and to transmit data between the one or more electronic components and the information handling system device; firmware configured to set an indicator before memory is allocated to the interface core, wherein the indicator is set by the firmware when the system is powered up to cause the control logic to report a memory requirement to the information handling system device larger than a programmed memory space expected by the control logic to decode by the control logic, and the indicator is cleared by software executed by the information handling system device after the information handling system device is booted; and a Single Root Input/Output Virtualization (SR-IOV) feature resident in a memory region allocated by the information handling system device based on the memory requirement reported by the control logic configured to test access to the SR-IOV feature, wherein the SR-IOV feature comprises an SR-IOV Virtual Function which is programmed to reside in a portion of the memory region that is not part of the programmed memory space expected by the control logic once the indicator is cleared by software.
