Abstract
An enhanced migration descriptor migrates a plurality of source sub-pages in a large source page accessible by direct memory access devices. A splitter and selector are integrated into a configuration of a computer. Responsive to a request to migrate a large page containing the plurality of source sub-pages in the source page, the splitter divides a plurality of high order page numbers from a plurality of low order page numbers. The selector selects the high order page number of the large page and creates an enhanced migration descriptor comprising the high order page number and a size of the large page. The selector, by the enhanced migration descriptor, combines the low order page number for a sub-page with the destination address and size of the enhanced migration descriptor to migrate the large page and each of the plurality of sub-pages.
