    摘要： An apparatus, method and program product for controlling the transfer of data in a data processing system having a processor handling an I/O request in an I/O operation, main storage controlled by the processor for storing data, and one or more I/O devices for sending data to or receiving data from said main storage. The apparatus includes a vector mechanism operable to register I/O requests by the devices to send or receive data from said main storage. A dispatcher is included which is operable to poll the vector mechanism to determine if there is an outstanding I/O request. An override bit has a first condition when an immediate interrupt is to be sent to the processor for handling an I/O request from the I/O device(s), and a second condition when the dispatcher is to poll the vector mechanism to determine if there is an outstanding I/O request. The override bit is set to its first condition or reset to its second condition by the processor.

    摘要： An apparatus, method and program product for sending data to or receiving data from one or more I/O devices in an I/O operation with a main storage controlled by a processor in a data processing system. The apparatus includes a time-of-day (TOD) register for containing a TOD value, a clock for containing a current TOD value, and a summary register having a first condition when any one of said devices requests an I/O operation and a second condition when no devices have an outstanding I/O request, each device having an outstanding I/O request sets the summary register to its first condition only when the summary register is in its second condition, and further places the current TOD value in the TOD register. A checking program determines if a specified time delay has been exceeded between the value in said TOD register and the current TOD for each requested I/O operation. The checking program drives an interrupt to the processor when the specified time delay has been exceeded.

    摘要： A method, system, program product and computer data structure for providing for two levels of server virtualization. A first hypervisor enables multiple logical partitions to share a set of resources and provides a first level of virtualization. A second hypervisor enables multiple, independent virtual machines to share the resources that are assigned to a single logical partition and provides a second level of virtualization. All events for all of the virtual machines within said single logical partition are grouped into a single partition-owned event queue for receiving event notifications from the shared resources for that single logical partition. A request for an interrupt is signaled for the grouped events from the partition-owned event queue for the demultiplexing of grouped events, by the machine, from the partition-owned event queue into individual, virtualized event queues that are allocated on a per virtual machine basis.
