Abstract: 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.

Abstract: A state of an input/output (I/O) operation in an I/O processing system is determined. A request for performing the I/O operation is received from an I/O operating system at a channel subsystem and forwarded to a control unit controlling an I/O device for executing the I/O operation. After a predetermined amount of time passes without receiving indication from the control unit that the I/O operation is completed, an interrogation request is received at the channel subsystem from the I/O operating system for determining the state of the I/O operation. An interrogation command is sent from the channel subsystem to the control unit. A response is received from the control unit, the response indicates a state of the I/O device executing the I/O operation, a state of the control unit controlling the I/O device executing the I/O operation, and the state of the I/O operation being executed.
