Abstract
A state indicator associated with a cache line is stored, wherein the cache line is one of a plurality of cache lines each associated with a corresponding unique section of a region of system memory. The state indicator comprises a dirty indication indicating that the cache line is a candidate for writing data stored in the cache line to the associated section of the region of system memory. The state indicator is one of a plurality of state indicators each associated with a corresponding cache line. For the region of system memory, a number of the plurality of state indicators that comprises the dirty indication is determined, and if a threshold is exceeded, data stored in a selected cache line is written to the associated section of the region of system memory, and a clean indication is stored in the state indicator corresponding to the cache line.
