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： Replacing a failing physical processor in a computer supporting multiple logical partitions, where the logical partitions include dedicated partitions and shared processor partitions, the dedicated partitions are supported by virtual processors having assigned physical processors, and the shared processor partitions are supported by pools of virtual processors. The pools of virtual processors have assigned physical processors. Embodiments operate generally by assigning priorities to the dedicated partitions and to the pools of virtual processors; detecting a checkstop of a failing physical processor; retrieving the failing physical processor's state; replacing by a hypervisor the failing physical processor with a replacement physical processor assigned to a dedicated partition or pool, which dedicated partition or pool has the lowest priority among the priorities of the dedicated partitions and pools; and assigning the retrieved state of the failing physical processor as the state of the replacement physical processor.

摘要： Methods, systems, and articles of manufacture for allowing an update to an executable component, such as a logical partitioning operating system, running on a computer system without requiring a reboot (or IPL) of the computer system are provided. Processors or tasks executing in a portion of code being updated may be forced to a known or “quiesced” state (e.g., designated wait points) before applying the update. If any of the processors or tasks are not in their quiesced state, the update is not applied or may be rescheduled for a later time, in an effort to allow the system to reach the quiesced state.

摘要翻译： 提供了用于允许更新在计算机系统上运行的可执行组件（诸如逻辑分区操作系统）的方法，系统和制品，而不需要计算机系统的重启（或IPL）。 在更新的代码的一部分中执行的处理器或任务可能在应用更新之前被强制为已知或“静态”状态（例如，指定的等待点）。 如果处理器或任务中的任何一个处于静止状态，则不会更新该应用程序，或者可能会在稍后的时间内重新安排更新程序，以使系统达到静默状态。

摘要： A method and system for selecting the architecture level to which a processor appears to conform within a computing environment when executing specific logical partitions or programs and performing migration among different levels of processor architecture. The method utilizes a “processor compatibility register” (PCR) that controls the level of the architecture that the processor appears to support. In one embodiment, the PCR is accessible only to super-privileged software. The super-privileged software sets bits in the PCR that specify the architecture level that the processor is to appear to support so that when the program runs on the processor, the processor behaves in accordance with the architecture level for which the program was designed.
