摘要： Mechanisms are provided, in a data processing system having a processor and a transactional memory, for executing a transaction in the data processing system. These mechanisms execute a transaction comprising one or more instructions that modify at least a portion of the transactional memory. The transaction is suspended in response to a transaction suspend instruction being executed by the processor. A suspended block of code is executed in a non-transactional manner while the transaction is suspended. A determination is made as to whether an interrupt occurs while the transaction is suspended. In response to an interrupt occurring while the transaction is suspended, a transaction abort operation is delayed until after the transaction suspension is discontinued.

摘要： An approach identifies an amount of high order bits used to store a memory address in a memory address field that is included in a memory. This approach calculates at least one minimum number of low order bits not used to store the address with the calculation being based on the identified amount of high order bits. The approach retrieves a data element from one of the identified minimum number of low order bits of the address field and also retrieves a second data element from one of the one of the identified minimum number of low order bits of the address field.

摘要： In response to a hypervisor page fault for memory that is not resident in a shared memory pool, an I/O paging request is sent to an external storage paging space. In response to a paging service partition encountering an I/O paging error, a paging failure indication is sent to the hypervisor. A simulated machine check interrupt instruction is sent from the hypervisor to the shared memory partition and a machine check handler obtains control. The machine check handler performs data analysis utilizing an error log in an attempt to isolate the I/O paging error to a process or a set of processes in the shared memory partition. The process or set of processes associated with the I/O paging error, or the shared memory partition itself, may be terminated. Finally, the shared memory partition may clear or initialize the page associated with the I/O paging error.

摘要： A logically-partitioned computer, program product and method utilize a flexible and adaptable communication interface between a partition and a partition manager, which permits optimal handling of partition management operations such as state change operations and the like over a wide variety of circumstances. In particular, a partition is permitted to indicate, in connection with a request to perform a partition management operation, whether an asynchronous notification should be generated or suppressed in association with the performance of the partition management operation by a partition manager. As a result, asynchronous notifications are selectively generated in association with the performance of partition management operations based upon indications in the requests made by partitions for such operations.

摘要： 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.
摘要翻译：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。

摘要： Disclosed is a computer implemented method, computer program product, and apparatus to establish at least one paging partition in a data processing system. The virtualization control point (VCP) reserves up to the subset of physical memory for use in the shared memory pool. The VCP configures at least one logical partition as a shared memory partition. The VCP assigns a paging partition to the shared memory pool. The VCP determines whether a user requests a redundant assignment of the paging partition to the shared memory pool. The VCP assigns a redundant paging partition to the shared memory pool, responsive to a determination that the user requests a redundant assignment. The VCP assigns a paging device to the shared memory pool. The hypervisor may transmit at least one paging request to a virtual asynchronous services interface configured to support a paging device stream.

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： A method, system, and article of manufacture for processing virtual interrupts in a logically partitioned system are provided. An intelligent virtual global interrupt queue (virtual GIQ) that may be associated with a plurality of virtual processors running in a logical partition may be utilized. Upon receiving a virtual interrupt, the virtual GIQ may examine the operating states of the associated virtual processors. In an effort to ensure the virtual interrupt is processed as quickly as possible, the virtual GIQ may present the virtual interrupt to one of the associated virtual processors determined to be in an operating state best suited for processing the virtual interrupt.
