Patent number: 10698845Abstract: Input/output (I/O) operation requests from pageable storage mode guests are interpreted without host intervention. In a pageable mode virtual environment, requests issued by pageable storage mode guests are processed by one or more processors of the environment absent intervention from one or more hosts of the environment. Processing of the requests includes manipulating, by at least one processor on behalf of the guests, buffer state information stored in host storage. The manipulating is performed via instructions initiated by the guests and processed by one or more of the processors.Type: GrantFiled: February 21, 2019Date of Patent: June 30, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Janet R. Easton, William A. Holder, Bernd Nerz, Damian L. Osisek, Gustav E. Sittmann, III, Richard P. Tarcza, Leslie W. Wyman

Patent number: 8862834Abstract: Aspects include a system, method and computer program product for providing a shared memory translation facility. The method includes receiving a request for access to a memory address from a requestor at a configuration, the receiving at a shared memory translation mechanism. It is determined whether the memory address refers to a shared memory object (SMO), the SMO accessible by a plurality of configurations managed in different zones of memory. Based on determining that the memory address refers to the SMO, it is determined whether the configuration has access to the SMO. Based on determining that the configuration has access to the SMO, the requestor is provided a system absolute address for the SMO and access to the SMO. In this manner direct interchange of data between the configuration and the plurality of configurations is allowed.Type: GrantFiled: July 25, 2013Date of Patent: October 14, 2014Assignee: International Business Machines CorporationInventors: Dan F. Greiner, Lisa C. Heller, Damian L. Osisek, Erwin Pfeffer, Donald W. Schmidt, Jaya Srikrishnan, Charles F. Webb, Leslie W. Wyman
