Estimating the term…
A computer system includes an adapter, a processor, and a memory storing program code, the program code executable by the processor to determine the adapter is single root input/output virtualization (SR-IOV) capable, to determine that an operating system is capable of using the adapter in SR-IOV mode, to configure the adapter in SR-IOV mode by generating an SR-IOV function associated with the adapter, and to assign control of the SR-IOV function to the operating system.
A method of managing an adapter, the method comprising:
The method of 1, further comprising controlling the adapter via the SR-IOV function, wherein the adapter is not configurable directly within the operating system.
The method of 1, wherein the SR-IOV function is at least one of a virtual peripheral component interconnect (PCI) function, a virtual PCI host bridge function, and a virtual root port function.
The method of 1, further comprising using the SR-IOV function to configure the adapter in SR-IOV mode according to an adapter profile.
The method of 1, further comprising selectively determining not to configure the adapter in SR-IOV mode and enabling the operating system to operate the adapter as a legacy PCI adapter.
The method of 1, further comprising correlating the SR-IOV function to a non-SR-IOV function using a virtualization intermediary.
The method of 8, further comprising using the non-SR-IOV function to modify an operational status of the adapter.
An apparatus, comprising:
The apparatus of 14, further the SR-IOV function is used by the operating system to configure the adapter according to an adapter profile, and wherein the adapter is not configurable directly within the operating system.
The apparatus of 1, wherein the program code is further executable by the processor to correlate the SR-IOV function to a non-SR-IOV function using a virtualization intermediary.
The apparatus of 17, wherein the operating system uses the non-SR-IOV function to modify an operational status of the adapter, wherein the operational status includes at least one of:
A computer program product comprising a computer usable medium having computer usable program code embodied therewith, the computer usable program code executable by a processor to:
