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.
摘要翻译：一种用于在执行特定逻辑分区或程序并且在不同级别的处理器架构之间执行迁移时，选择处理器在计算环境内符合的架构级别的方法和系统。该方法利用“处理器兼容性寄存器”（PCR）来控制处理器似乎支持的架构级别。在一个实施方案中，PCR仅可用于超特权软件。超级特权软件设置PCR中的位，指定处理器将要支持的架构级别，以便当程序在处理器上运行时，处理器的行为与程序设计的架构级别相符。

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： 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.
