Abstract
A duplicate memory image of the pages that need to be saved (i.e. hibernated) is created within volatile memory. The pages to be hibernated include all pages whose state is locked and a portion, if not all, of the pages whose state is idle. If the duplicate memory image of the pages to be hibernated cannot, however, be created due to a lack of volatile memory, a portion of the idle pages is pushed out to the swap file on secondary storage to free more volatile memory for this duplication. This duplicate memory image of the pages to be hibernated along with a corresponding page table identifying their location within volatile memory are then written out to a file on the secondary storage, completing hibernation and allowing the computer system to shut down in a hibernate mode.
