Abstract
Host page management assist functions are employed to manage storage of a pageable mode virtual environment. These functions enable storage to be managed by a processor of the environment absent intervention of a host of the environment. The functions include a resolve host page function; a pin function; and unpin functions.
Claims25
A system of facilitating management of storage of a pageable mode virtual environment, said system comprising:
- a CPU of the pageable mode virtual environment;
- and
- means for managing storage of the pageable mode virtual environment, the managing being performed by the CPU absent intervention of a host of the pageable mode virtual environment, wherein the means for managing comprises means for resolving by the CPU a storage fault absent intervention by the host and eliminating context switching overhead between the host and a guest of the pageable mode virtual environment.
A system of facilitating management of storage of a pageable mode virtual environment, said system comprising:
- a CPU of the pageable mode virtual environment to manage storage of the pageable mode virtual environment absent intervention of a host of the pageable mode virtual environment, wherein the managing comprises resolving by the CPU a storage fault absent intervention by the host and eliminating context switching overhead between the host and a guest of the pageable mode virtual environment.
An article of manufacture comprising:
- at least one computer usable non-transitory medium having computer readable program code logic to manage storage of a pageable mode virtual environment, the computer readable program code logic comprising:
- manage logic to manage storage of a pageable mode virtual environment, the managing being performed by a CPU of the pageable mode virtual environment absent intervention of a host of the pageable mode virtual environment, wherein the manage logic comprises resolve logic to resolve by the CPU a storage fault absent intervention by the host and eliminating context switching overhead between the host and a guest of the pageable mode virtual environment.
