Abstract
A single root I/O virtualization (SR-IOV) capable peripheral component interconnect (PCI) device may be operable to configure resources to transparently operate in a non-SR-IOV environment utilizing a physical function (PF) and one or more hybrid functions (HFs). In instances when the SR-IOV capable PCI device is operating in a SR-IOV environment, the SR-IOV capable PCI device may expose a VF configuration space in the hybrid function to an associated PCI driver for configuring the hybrid function as a virtual function. In instances when the SR-IOV capable PCI device is operating in a non-SR-IOV environment, the SR-IOV capable PCI device may hide a SR-IOV extended header in the physical function from the associated PCI driver and expose a PF configuration space in the hybrid function to the associated PCI driver for configuring the hybrid function as a physical function.
