Abstract:
A method includes selectively routing a physical address to an originating device instead of to a shared memory at controller that manages conversion of device virtual addresses to physical addresses. The physical address corresponds to a data access from a virtual device. The method may provide local coherency at a computing system that implements virtualized input/output.
