摘要： A computer implemented method, apparatus, and system for sharing an input/output adapter among a plurality of operating system instances on a host server. Virtual memory is allocated and associated with an operating system instance. The virtual memory is translated to one or more real addresses, wherein the one or more real addresses require no further translation. The input/output adapter is exposed to the one or more real addresses. The operating system instance is provided with the one or more real addresses for accessing the virtual memory associated with the operating system instance. Address translation and protection may be performed by the input/output adapter or by the operating system instance.

摘要： A method, computer program product, and distributed data processing system for directly sharing a network stack offload I/O adapter that directly supports resource virtualization and does not require a 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 one or more virtual resources that reside within a physical adapter, such as a PCI, PCI-X, or PCI-E adapter, and that are associated with a virtual host. 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 host to adapter communications. A mechanism is provided for directly creating and initializing one or more virtual resources that reside within a physical adapter, such as a PCI, PCI-X, or PCI-E adapter, and that are associated with a virtual host.

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 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.
