摘要： Methods and systems for managing reset of a physical function of an I/O device in a computing system are disclosed, where the physical function is included in a single-root PCI manager. One method includes maintaining a count of active virtual functions associated with the physical function included in the single-root PCI manager, and, upon determining that no active virtual functions are associated with the physical function, allowing the physical function to be reset within the single-root PCI manager. The method further includes while resetting the physical function, persisting a configuration memory space associated with the physical function, and associating the persisted configuration memory space with the physical function after the physical function is reset.

摘要： Methods and systems for allocating, one or more virtual functions of a plurality of virtual functions associated with physical functions of I/O interface devices of a computing device are described. One method includes managing one or more physical functions of an I/O interface device within an interconnect partition of a multi-partition virtualization system implemented at least in part on the computing device. The method further includes, during a boot process of a second partition on the computing device, parsing a file to determine an assignment of one or more virtual functions to the second partition and associate each of the one or more virtual functions to corresponding physical functions.

摘要： Methods and systems for instantiating a virtual function in a partition of a multi-partition virtualization system implemented at least in part on a computing device are disclosed. One method includes initializing a partition on the computing device, including determining a virtual function to be associated with the partition, the virtual function associated with a physical function of an I/O device, and, prior to attaching a processor to the partition, determining if the physical function is in a ready state and capable of being associated with the virtual function. The method further includes, upon determining that the physical function is in the ready state and capable of being associated with the virtual function, attaching the processor to the partition, thereby allowing the partition to begin execution.

摘要： Methods and systems for supporting multifunction virtualization within SR-IOV in a multi-partition virtualization system are described. One method includes instantiating a physical function of an I/O interface device within an interconnect partition of a multi-partition virtualization system implemented at least in part on the computing device, and instantiating a plurality of virtual functions within a guest partition of the multi-partition virtualization system, each of the plurality of virtual functions associated with a physical function. The method includes assigning a bus identifier, a device identifier, and a function identifier to each of the plurality of virtual functions, the plurality of virtual functions including a first virtual function associated with a first bus identifier and a first device identifier and a second virtual function associated with the first bus identifier and the first device identifier.
