Abstract: As described herein, for a selected process identifier and virtual address, a page fault arising from multiple sources can be solved by a one-time operation. The selected process identifier can include a virtual function (VF) identifier or process address space identifier (PASID). In some examples, solving a page fault arising from multiple sources by a one-time operation comprises invoking a page fault handler to determine an address translation.
