Address remapping technologies are described. A method can include receiving, at a paging device of a system memory, a first physical address of an input/output (IO) device from a sub-page translator, where a sub-page location indicator may be associated with the first physical address. The method can further include identifying a virtual address in a sub-page translation table based on the physical address when the sub-page location indicator may be set to a sub-page lookup mode. The method can further include determining when to lookup the physical address in a sub-page translation table based on the sub-page location indicator. The method can further include communicating, to a virtual machine, the virtual address. |
