Abstract
Dynamic memory area configuration includes designating a portion of memory as a specialized memory unit, and reserving a first portion of specialized memory unit for a plurality of page frame table entries (PFTEs) representing a plurality of frames in the specialized memory. One or more of the PFTEs are stored in respective queue entries within a queue in a reserved area of the specialized memory unit. A particular queue entry indicates that a particular PFTE associated with a particular frame is available for use. An offline request to take a second portion of the specialized memory unit offline is received. Whether to fulfill the offline request is determined based on whether the second portion of the specialized memory unit has an associated queue entry within the queue indicating that the associated frame is not in use back a portion of a page frame table (PFT) or the specialized memory unit.
