Abstract:
1. A computer implemented method for partition redispatching using page tracking, the computer implemented method comprising: detecting a page address miss in a page addressing buffer; finding an effective page address to real page address mapping for the page address miss to form a found real page address and page size combination; saving the found real page address and page size combination as an entry in a set of entries in an array; updating the set of entries in the array to track page use; creating a preserved array from the array in response to determining a partition is an undispatched partition, wherein address entries for only the undispatched partition are saved in the preserved array, wherein the partition is a subset of a data processing system's resources, and wherein an undispatched partition is a partition that is not presently executing; analyzing each entry of the preserved array for a compressed page responsive to determining that the undispatched partition is now redispatched; and decompressing a compressed page, responsive to determining the compressed page referenced by one of the set of entries in the array.
