摘要： A method, computer program product, and distributed data processing system that enables host software or firmware to allocate virtual resources to one or more system images from a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, is provided. Adapter resource groups are assigned to respective system images. An adapter resource group is exclusively available to the system image to which the adapter resource group assignment was made. Assignment of adapter resource groups may be made per a relative resource assignment or an absolute resource assignment. In another embodiment, adapter resource groups are assigned to system images on a first come, first served basis.

摘要： A mechanism for handling event notifications or interrupts in a logically partitioned computing system having IO adapters that support adapter virtualization are provided. A virtual adapter associated with a physical IO adapter detects an event, identifies a logical partition associated with the event, and writes an event notification entry in a partition interrupt control block (PICB) of the logical partition memory space. The virtual adapter notifies shared control point logic on the physical IO adapter of the update to the PICB which may then write an entry to a logical partition manager interrupt control block (LPAR manager ICB) identifying the update to the PICB and the operating system associated with the PICB. The LPAR manager may then inform the operating system of the logical partition of the updates to the PICB which may then read the entries in the PICB, process them and inform appropriate application instances of the events.
