摘要: Various approaches for demoting a memory page are described. In one approach, a first new page is established from a subpage of a base page in response to a request to demote a specified subpage. The size of the first new page is selected from a plurality of page sizes. For each portion of the base page less the first new page, the portion is divided into one or more pages of a selected size. The selected size for the pages is a largest of the plurality of page sizes that is less than or equal to the size of the portion. If the new one or more pages do not encompass the entire portion, a new feasible, largest of the sizes is selected and the part of the portion not encompassed is further divided into one or more pages.
