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: 8819393Abstract: Host page management assist functions are employed to manage storage of a pageable mode virtual environment.

Patent number: 8762615Abstract: A command is issued to reset one or more pending interrupt indicators and arbitrate for ownership of the interrupt. Responsive to a processor receiving the command, a check is made of a selected pending interrupt indicator. If the selected pending interrupt indicator is not set, another pending interrupt indicator is checked, instead of providing a negative response and reissuing the command. In this way, one dequeue command can replace multiple dequeue commands and the overhead of leaving and re-entering the interrupt handler is reduced. A negative response is reserved for those situations in which there are no pending interrupt indicators to be reset.Type: GrantFiled: December 21, 2011Date of Patent: June 24, 2014Assignee: International Business Machines CorporationInventors: Janet R. Easton, Norbert Hagspiel, Bernd Nerz

Patent number: 8601497Abstract: One or more message signaled interruption requests from one or more input/output (I/O) adapters are converted to I/O adapter event notifications. Each I/O adapter event notification includes the setting of one or more specific indicators in system memory and an interruption request, the first of which results in a pending I/O adapter interruption request. While a request for an I/O adapter interruption is pending, subsequent message signaled interruption requests are converted to I/O adapter event notifications, but do not result in additional requests for I/O adapter interruptions.Type: GrantFiled: May 2, 2012Date of Patent: December 3, 2013Assignee: International Business Machines CorporationInventors: David Craddock, Janet R. Easton, Mark S. Farrell, Thomas A. Gregg, Eric N. Lais, Cynthia Sittmann

Patent number: 8478922Abstract: The conditions under which adapter interruptions are made pending are controlled. Responsive to an interruption being presented to an operating system, subsequent interruptions are suppressed on all central processing units in the configuration. The operating system processes the interruption, including examining and processing indicators of reported events until the operating system discontinues the suppression. This enables the operating system to control the number of pending interruptions and the number of processors processing those interruptions.Type: GrantFiled: June 23, 2010Date of Patent: July 2, 2013Assignee: International Business Machines CorporationInventors: Brenton F. Belmar, David Craddock, Janet R. Easton, Mark S. Farrell, Thomas A. Gregg, Damian L. Osisek, Donald W. Schmidt, Gustav E. Sittmann, III, Richard P. Tarcza

Patent number: 8468284Abstract: One or more message signaled interruption requests from one or more input/output (I/O) adapters are converted to I/O adapter event notifications while retaining the message vector indication. An I/O adapter event notification may be routed and presented to a host or to a guest that the host is executing. To present the notification to the correct host or to the correct guest, various data structures in host and/or guest memory are used.Type: GrantFiled: June 23, 2010Date of Patent: June 18, 2013Assignee: International Business Machines CorporationInventors: Frank W. Brice, Jr., David Craddock, Janet R. Easton, Mark S. Farrell, Thomas A. Gregg, Damian L. Osisek, Gustav E. Sittmann, III
