摘要： A computer program product and distributed data processing system that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to validate that a direct memory access address referenced by an incoming I/O transaction that was initiated through a memory mapped I/O operation are associated with a virtual adapter or virtual resource that is referenced by the incoming memory mapped I/O operation is provided. 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 single physical I/O adapter validates that one or more direct memory access addresses referenced by an incoming I/O transaction initiated through a memory mapped I/O operation are associated with a virtual adapter or virtual resource that is referenced by the incoming memory mapped I/O operation.

摘要： A direct memory access (DMA) device includes a barrier and interrupt mechanism that allows interrupt and mailbox operations to occur in such a way that ensures correct operation, but still allows for high performance out-of-order data moves to occur whenever possible. Certain descriptors are defined to be “barrier descriptors.” When the DMA device encounters a barrier descriptor, it ensures that all of the previous descriptors complete before the barrier descriptor completes. The DMA device further ensures that any interrupt generated by a barrier descriptor will not assert until the data move associated with the barrier descriptor completes. The DMA controller only permits interrupts to be generated by barrier descriptors. The barrier descriptor concept also allows software to embed mailbox completion messages into the scatter/gather linked list of descriptors.
摘要翻译：直接存储器访问（DMA）设备包括屏障和中断机制，允许中断和邮箱操作以确保正确操作的方式发生，但仍然允许在可能的情况下发生高性能无序数据移动。某些描述符被定义为“屏障描述符”。当DMA设备遇到屏障描述符时，它确保所有先前的描述符在屏障描述符完成之前完成。 DMA设备进一步确保在与屏障描述符关联的数据移动完成之前，屏障描述符产生的任何中断都不会断言。 DMA控制器仅允许由屏障描述符生成中断。屏障描述符概念还允许软件将邮箱完成消息嵌入到描述符的分散/收集链接列表中。

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.

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。
