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 method, computer program product, and distributed data processing system for directly sharing an I/O adapter that directly supports adapter virtualization and does not require an LPAR manager or other intermediary to be invoked on every I/O transaction is provided. The present invention also provides a method, computer program product, and distributed data processing system for directly creating and initializing a virtual adapter and associated resources on a physical adapter, such as a PCI, PCI-X, or PCI-E adapter. Specifically, the present invention is directed to a mechanism for sharing conventional PCI (Peripheral Component Interconnect) I/O adapters, PCI-X I/O adapters, PCI-Express I/O adapters, and, in general, any I/O adapter that uses a memory mapped I/O interface for communications. A mechanism is provided for directly creating and initializing a virtual adapter and associated resources within a physical adapter, such as a PCI, PCI-X, or PCI-E adapter. Additionally, each virtual adapter has an associated set of host side resources, such as memory addresses and interrupt levels, and adapter side resources, such as adapter memory addresses and processing queues, and each virtual adapter is isolated from accessing the host side resources and adapter resources that belong to another virtual or physical adapter.

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。

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 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 mechanism for modifying resources in a logically partitioned data processing system is provided. A request to modify resources associated with a virtual adapter allocated on a physical adapter is invoked. The resources associated with the virtual adapter comprise a subset of the physical adapter resources. The request to modify the physical adapter is conveyed to the physical adapter. Responsive to receipt of the request by the physical adapter, the physical adapter modifies the resources allocated to the virtual adapter.

摘要： A method, computer program product, and distributed data processing system that enables host software or firmware to map PCI adapter virtual resources to PCI bus addresses that are associated with a system image is provided. Virtual addresses maintained in a protection table segment assigned to a system image are mapped to physical addresses defined in entries of an address table segment assigned to the system image. Discontiguous memory regions identified in entries of the address table segment may thus be mapped to a contiguous virtual address space.
