    摘要： A method in a data processing system is provided for processing a service request of a client partition. The method includes: obtaining by a service partition of the data processing system the service request from the client partition, wherein both the client and service partitions execute above a hypervisor of the data processing system; and processing the service request by the service partition utilizing a processor quantum assigned to the client partition and donated by the client partition to the service partition. The client partition controls scheduling of the service partition by queuing the service request at the client partition until the client partition decides to proceed with execution of the service request by the service partition. In one implementation, the service partition is a partition adjunct of the data processing system, which utilizes donated virtual address space of the client partition.

    摘要： Systems and methods to communicate data frames are provided. A particular apparatus may include a first adapter having a first queue configured to store a data frame associated with a first priority. The adapter is configured to generate a first priority pause frame. A distributed virtual bridge may be coupled to the first adapter. The distributed virtual bridge may include an integrated switch router and a first transport layer module configured to provide a frame-based interface to the integrated switch router. The transport layer module may include a first buffer associated with the first priority. A first bridge element of the distributed virtual bridge may be coupled to the first adapter queue and to the first transport layer module. The first bridge element is configured to receive the first priority pause frame from the adapter and to communicate an interrupt signal to the first transport layer module to interrupt delivery of the data frame to the first queue.

    摘要： A partition adjunct is provided for a logical partition running above a hypervisor of a data processing system. The partition adjunct, which is a separate dispatchable partition from an instantiating logical partition, provides one or more services to the logical partition. A service request received from the logical partition is processed by the partition adjunct utilizing virtual address space donated to the partition adjunct from the logical partition. The partition adjunct and the logical partition share a common virtual address to real address page table, and context switching the current state machine from the logical partition to the partition adjunct occurs without invalidating or modifying state data of selected memory management and address translation hardware of the data processing system. In a hardware multithreaded system, the partition adjunct is dispatched on a single thread, while another thread continues to run in the logical partition initiating the service request.

    摘要： Dedicated access is provided to a physical input/output (I/O) device which is non-configurable by an initiating logical partition. Access is established by: initiating, by the logical partition, creation of a partition adjunct; invoking a hypervisor of the data processing system to instantiate the partition adjunct with resources donated from the initiating logical partition, the donated resources including a donated virtual address space of the logical partition and the physical I/O device; creating, by the hypervisor, the partition adjunct and assigning the donated virtual address space and donated physical I/O device to the created partition adjunct; and interfacing, by the hypervisor, the logical partition and the created partition adjunct, the interfacing including providing the logical partition with a virtual I/O device which replaces the donated physical I/O device, and which is configurable by the logical partition.

    摘要： In an embodiment, a command is received that requests movement of ownership of a target device from an origin compute element to a destination compute element. From the origin compute element, a translation of a virtual bridge identifier to a first secondary bus identifier, a first subordinate bus identifier, and a first MMIO bus address range is removed. To the destination compute element, a translation of the target virtual bridge identifier to a second secondary bus identifier, a second subordinate bus identifier, and a second MMIO bus address range is added. From a south chip that comprises the target virtual bridge, a translation of the target virtual bridge identifier to an identifier of the origin compute element is removed. To the south chip, a translation of the target virtual bridge identifier to an identifier of the destination compute element is added.

    摘要： In an embodiment, a translation of a physical bus number to a hierarchical bus number is written to a south chip. The south chip receives a configuration write command that comprises a physical bus number. The south chip sends the configuration write command to a device via the bus identified by the physical bus number, and the device stores the physical bus number in the device. In response to a received message from a device that comprises the physical bus number, the south chip replaces the physical bus number in the message with the hierarchical bus number. The south chip sends the message to a north chip via a point-to-point serial link. Both the physical bus number and the hierarchical bus number identify a bus with which the device connects to a bridge in the south chip.
