    摘要: Described herein are methods and system for virtualization of the secure digital (SD) host controller to enable sharing a SD device among various multiple host processors in a multi-processor computing system. In one implementation the method of sharing a SD device amongst a plurality of hosts of a multi-host computing system comprises detecting the SD device on occurrence of a reset event, receiving an enumeration request, from at least a first host and a second host of the plurality of hosts, to enumerate the SD device with respect to the second host, enumerating the SD device with respect to the second host, and initiating data exchange between the SD device and each of the plurality of hosts.

    摘要: Systems and methods for sharing a single root I/O virtualization (SR-IOV) device (106) amongst a plurality of roots (104) are described herein. The described systems implement a method which includes identifying a physical function (PF) and a plurality of virtual functions (VFs) associated with the SR-IOV device (106). The method also include generating at least one set of VFs from amongst the plurality of identified VFs, where each set of VFs include one or more VFs, and generating a pseudo PF (PPF) for each of the at least one set of VFs, where each PPF and a set of VFs associated with the PPF forms a projected SR-IOV device (106). The method further includes associating each of the projected SR-IOV device (106) with a root (104) from amongst the plurality of roots (104) to allow sharing of the SR-IOV device (106).
