摘要： A resource and partition manager virtualizes interrupts without using any additional hardware in a way that does not disturb the interrupt processing model of operating systems running on a logical partition. In other words, the resource and partition manager supports virtual interrupts in a logically partitioned computer system that may include share processors with no changes to a logical partition's operating system. A set of virtual interrupt registers is created for each virtual processor in the system. The resource and partition manager uses the virtual interrupt registers to process interrupts for the corresponding virtual processor. In this manner, from the point of view of the operating system, the interrupt processing when the operating system is running in a logical partition that may contain shared processors and virtual interrupts is no different that the interrupt processing when the operating system is running in computer system that only contains dedicated processor partitions.

摘要： Diagnostic data, such as a time increment corresponding to how long a thread waits to access a shared resource, is stored within a predetermined location in a data structure, such as a hash bucket in a hash table. The location is preferably correlated to the resource such that a display of the diagnostic data may be tailored to reflect a user-specified relationship between the data and resource.

摘要： A logical partition debugger allows debugging one logical partition in a computer system without requiring the shutdown of other logical partitions. The logical partition debugger is implemented in software in the partition manager. The logical partition debugger provides many common debug functions known in existing hardware and software debuggers, but does so in a manner that only the partition being debugged is affected.

摘要： An apparatus, program product, and method utilize a memory access interrupt to effect a reset of a processor in a multi-processor environment. Specifically, a source processor is permitted to initiate a reset of a target processor simply by generating both a reset request and a memory access interrupt for the target processor. The target processor is then specifically configured to detect the presence of a pending reset request during handing of the memory access interrupt, such that the target processor will perform a reset operation responsive to detection of such a request.

摘要： An apparatus, program product and method support the deallocation of a data structure in a multithreaded computer without requiring the use of computationally expensive semaphores or spin locks. Specifically, access to a data structure is governed by a shared pointer that, when a request is received to deallocate the data structure, is initially set to a value that indicates to any thread that later accesses the pointer that the data structure is not available. In addition, to address any thread that already holds a copy of the shared pointer, and thus is capable of accessing the data structure via the shared pointer after the initiation of the request, all such threads are monitored to determine whether any thread is still using the shared pointer by determining whether any thread is executing program code that is capable of using the shared pointer to access the data structure. Once this condition is met, it is ensured that no thread can potentially access the data structure via the shared pointer, and as such, the data structure may then be deallocated.
摘要翻译：一种装置，程序产品和方法支持多线程计算机中数据结构的释放，而不需要使用计算上昂贵的信号量或旋转锁。具体来说，访问数据结构由共享指针控制，当接收到请求以解除分配数据结构时，共享指针最初被设置为指示稍后访问指针的任何线程数据结构不可用的值。此外，为了解决已经拥有共享指针的副本的任何线程，并且因此能够在请求启动之后通过共享指针访问数据结构，所有这些线程被监视以确定是否有任何线程仍在使用该共享指针通过确定任何线程是否正在执行能够使用共享指针来访问数据结构的程序代码。一旦满足此条件，就确保没有线程可以通过共享指针潜在地访问数据结构，因此可以解除分配数据结构。

摘要： A partition manager includes an I/O reconfiguration mechanism and a logical partition suspend/resume mechanism that work together to perform autonomic I/O reconfiguration in a logically partitioned computer system. When I/O reconfiguration is required, the affected logical partitions are suspended, the I/O is reconfigured, and the affected logical partitions are resumed. Because the logical partitions are suspended during I/O reconfiguration, any ghost packet that may occur when the I/O is reconfigured is ignored.

摘要： An apparatus, program product and method for tracking the state of a migrating logical partition. Embodiments may use the state to determine the readiness and/or appropriateness of a page of the logical partition for transferring. The state may include a value or other data used to track changes affecting the page or the relative ease and/or appropriateness of migrating the page. A page manager table with entries corresponding to the state of each page of the logical partition may be used to track the state while the logical partition continues to run during a migration.

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.
