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： 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： Access control to shared virtual address space within a single logical partition is provided. The access control includes: associating, by a hypervisor of the data processing system, a memory protection key with a portion of a single logical partition's virtual address space being shared by multiple entities, the key preventing access by one of the multiple entities to that portion of the virtual address space, and allowing access by another of the entities to that portion of the virtual address space; and locking by the hypervisor the memory protection key from modification by the one entity, wherein the locking prevents the one entity from modifying the key and thereby gaining access to the portion of the single logical partition's virtual address space with the associated memory protection key. In one embodiment, the one entity is the single logical partition itself, and the another entity is a partition adjunct.

摘要： A firmware update process for a self-virtualizing IO resource such as an SRIOV adapter is incorporated into a platform firmware update process to systematically update the resource firmware in a manner that is for the most part transparent to the logical partitions sharing the adapter. In particular, resource firmware associated with a self-virtualizing IO resource is bundled with firmware for at least one adjunct partition associated with that self-virtualizing IO resource within a common firmware image so that, upon restart of the adjunct partition to use the updated firmware image, the resource firmware is also updated, with a logical partition that uses the self-virtualizing IO resource maintained in an active state during the restart, and without requiring the self-virtualizing IO resource to be deconfigured from the logical partition.
