More Information
Summary:A computer-implemented method, apparatus, and computer program product are disclosed for migrating data from a source physical page to a destination physical page. A migration process is begun to migrate data from the source physical page to the destination physical page which causes a host bridge to enter a first state. The host bridge then suspends processing of direct memory access operations when the host bridge is in the first state.
