    • A partition migration mechanism migrates a logical partition executing an operating system and resumes the logical partition before all resources in the logical partition have been migrated. When a partition is being migrated, a call checkpoint mechanism creates checkpoints of the state of the operating system when the partition manager is called. Before performing the call to the partition manager, a check is made to determine if all resources required by the call are available. If so, the partition manager call is executed. If all resources required by the call are not available, a resource fault is indicated, which causes the operating system state from the last checkpoint to be restored and a corresponding virtual CPU to be preempted until the resource that caused the fault becomes available. Exceptions that do not require the missing resource may be performed while the virtual CPU awaits the resource to become available.
    • 在迁移逻辑分区中的所有资源之前,分区迁移机制将迁移执行操作系统的逻辑分区并恢复逻辑分区。 当分区正在迁移时,调用检查点机制会在调用分区管理器时创建操作系统状态的检查点。 在执行对分区管理器的呼叫之前,进行检查以确定呼叫所需的所有资源是否可用。 如果是这样,则执行分区管理器调用。 如果呼叫所需的所有资源都不可用,则会指示资源故障,从而导致最后一个检查点的操作系统状态恢复,相应的虚拟CPU将被抢占,直到导致故障的资源变为可用。 可以在虚拟CPU等待资源变为可用时执行不需要缺少资源的异常。

    • A method, apparatus, and computer program product are disclosed in a data processing system for providing a virtualized time base in a logically partitioned data processing system. A time base is determined for each one of multiple processor cores. The time base is used to indicate a current time to one of the processor cores for which the time base is determined. The time bases are synchronized together for the processor cores such that each one of the processor cores includes its own copy of a synchronized time base. For one of the processor cores, a virtualized time base is generated that is different from the synchronized time base but that remains synchronized with at least a portion of the synchronized time base. The processor core utilizes the virtualized time base instead of the synchronized time base for indicating the current time to the processor core. The synchronized time bases and the portion of the virtualized time base remaining in synchronization together.
    • 在用于在逻辑分区的数据处理系统中提供虚拟时基的数据处理系统中公开了一种方法,装置和计算机程序产品。 为多个处理器核心中的每一个确定时基。 时基用于指示当前时间到其中确定时基的一个处理器内核。 对于处理器核心,时基同步在一起,使得每个处理器核心包括其自己的同步时基副本。 对于其中一个处理器核心,生成与同步时基不同的虚拟时基,但与同步时基的至少一部分保持同步。 处理器核心利用虚拟时基而不是同步的时基来指示处理器核心的当前时间。 同步的时基和虚拟时基的一部分保持同步在一起。

    • A method, apparatus, system, and signal-bearing medium that in an embodiment set a resource indicator to indicate that a processor is using a resource in a logically-partitioned electronic device, determine whether a current partition in the logically-partitioned electronic device owns the resource, and clear the resource indicator after the processor is done using the resource. When a partition gives up ownership of a resource, a resource ownership state is changed to indicate that the partition does not own a resource, and the partition waits to continue executing until other processors have cleared their respective resource indicators. In an embodiment, the resource indicator is in a cache line that is local to the processor, which allows resources to be dynamically allocated with improved performance.
    • 一种方法,装置,系统和信号承载介质,其在一个实施例中设置资源指示符以指示处理器正在逻辑分区的电子设备中使用资源,确定逻辑分区的电子设备中的当前分区是否拥有 资源,并在处理器完成资源后清除资源指示符。 当分区放弃资源的所有权时,将更改资源所有权状态以指示分区不拥有资源,并且分区等待继续执行,直到其他处理器清除其各自的资源指示符。 在一个实施例中,资源指示符位于处理器本地的高速缓存行中,这允许以改进的性能动态分配资源。
