Abstract

A technique for managing context state information enables a reduced number of save and restore operations. At least one embodiment includes a plurality of save area segments to store a plurality of machine context state information, which can be saved into the segments and restored to the machine state. One embodiment includes at least one in-use bit vector to indicate status of the plurality of machine context information stored in the segments, and another vector associated with the machine state.
