摘要： A method, computer program product, and distributed data processing system that allows a single physical I/O adapter to validate that a memory mapped I/O address referenced by an incoming I/O operation is associated with a virtual host that initiated the incoming memory mapped I/O operation is provided. Specifically, the present invention is directed to a mechanism for sharing a PCI family I/O adapter and, in general, any I/O adapter that uses a memory mapped I/O interface for communications. A mechanism is provided that allows a single physical I/O adapter to validate that a memory mapped I/O address referenced by an incoming memory mapped I/O operation used to initiate an I/O transaction is associated with a virtual host that initiated the incoming memory mapped I/O operation.

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.

摘要： A mechanism that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to perform I/O transactions using the PCI host bus, device, and function numbers to validate that an I/O transaction originated from the proper host is provided. Additionally, a method for facilitating identification of a transaction source partition is provided. An input/output transaction that is directed to a physical adapter is originated from a system image of a plurality of system images. The host data processing system adds an identifier of the system image to the input/output transaction. The input/output transaction is then conveyed to the physical adapter for processing of the input/output transaction.

摘要： A method, system, and computer program product for sharing adapter resources among multiple operating system instances. The present invention provides a mechanism for dynamically allocating virtualized I/O adapter resources. The present invention separates the operation of adapter resource allocation from adapter resource management. Protection attributes within the adapter resource context are used to allow the adapter to enforce access control over the adapter resources. The hypervisor allocates an available adapter resource to a given partition. The adapter is notified of the allocation, and the adapter updates its internal structure to reflect the allocation. The hypervisor may revoke ownership of and reassign adapter resources to another OS instance. In this manner, the allocation described above allows for the simple reassignment of resources from one partition to another.
摘要翻译：一种用于在多个操作系统实例之间共享适配器资源的方法，系统和计算机程序产品。本发明提供了一种动态分配虚拟化I / O适配器资源的机制。本发明将适配器资源分配的操作与适配器资源管理分开。适配器资源上下文中的保护属性用于允许适配器强制对适配器资源进行访问控制。管理程序将可用的适配器资源分配给给定的分区。适配器被通知分配，并且适配器更新其内部结构以反映分配。虚拟机管理程序可能会撤消将适配器资源的所有权重新分配给另一个OS实例。以这种方式，上述分配允许从一个分区到另一个分区的资源的简单重新分配。
