Abstract

Technologies for I/O device virtualization include a computing device with an I/O device that includes a physical function, multiple virtual functions, and multiple assignable resources, such as I/O queues. The physical function assigns an assignable resource to a virtual function. The computing device configures a page table mapping from a virtual function memory page located in a configuration space of the virtual function to a physical function memory page located in a configuration space of the physical function. The virtual function memory page includes a control register for the assignable resource, and the physical function memory page includes another control register for the assignable resource. A value may be written to the control register in the virtual function memory page. A processor of the computing device translates the virtual function memory page to the physical function memory page using the page mapping. Other embodiments are described and claimed.
