Abstract: Techniques for providing adaptive virtual function (VF) drivers capable of operating with physical devices having a plurality of different hardware configurations are described. In one embodiment, for example, an apparatus may include logic to implement a virtual machine (VM), the logic to initialize an adaptive virtual function (VF) driver to facilitate communication between the VM and a physical device to be virtualized, establish communication between the adaptive VF driver and a physical function (PF) driver of the hypervisor for the physical device, activate a standard feature set for the adaptive VF driver to execute on a PF of the physical device, and negotiate activation of an advanced feature set for the adaptive VF driver to execute on the PF, the adaptive VF driver to provide the advanced feature set to the PF, the PF activate each feature of the advanced feature set supported by the PF.

Abstract: Creating hybrid virtual devices using a plurality of physical functions. A processor of a device may identify a plurality of physical functions accessible to the device, the plurality of physical functions including a first physical function and a second physical function. The processor may create a virtual device to comprise the first physical function to provide a first capability and the second physical function to provide a second capability, wherein the first capability and second capability are different capabilities.
