摘要： An apparatus, program product and method for coordinating the distribution of CPUs as among logically-partitioned virtual processors. A virtual processor may yield a CPU to precipitate an occurrence upon which its own execution may be predicated. As such, program code may dispatch the surrendered CPU to a designated virtual processor.
摘要翻译：用于协调在逻辑分区虚拟处理器之间分配CPU的装置，程序产品和方法。虚拟处理器可能会产生一个CPU来沉淀其本身可执行的事件。因此，程序代码可以将投降的CPU分派到指定的虚拟处理器。

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 and method selectively invalidate entries in an address translation cache instead of invalidating all, or nearly all, entries. One or more translation mode bits are provided in each entry in the address translation cache. These translation mode bits may be set according to the addressing mode used to create the cache entry. One or more “hint bits” are defined in an instruction that allow specifying which of the entries in the address translation cache are selectively preserved during an invalidation operation according to the value(s) of the translation mode bit(s). In the alternative, multiple instructions may be defined to preserve entries in the address translation cache that have specified addressing modes. In this manner, more intelligence is used to recognize that some entries in the address translation cache may be valid after a task or partition switch, and may therefore be retained, while other entries in the address translation cache are invalidated.
摘要翻译：一种装置和方法选择性地使地址转换高速缓存中的条目无效，而不是使所有或几乎所有条目无效。在地址转换高速缓存中的每个条目中提供一个或多个翻译模式位。可以根据用于创建高速缓存条目的寻址模式来设置这些转换模式位。在指令中定义一个或多个“提示位”，该指令允许根据翻译模式位的值来指定在无效操作期间选择性地保留地址转换高速缓存中的哪些条目。在替代方案中，可以定义多个指令以保留具有指定寻址模式的地址转换高速缓存中的条目。以这种方式，使用更多的智能来识别地址转换高速缓存中的一些条目在任务或分区切换之后可能是有效的，并且因此可以被保留，而地址转换高速缓存中的其他条目是无效的。

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.

摘要： 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.

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： The present invention provides for storing and using a stored logical partition indicia in a TLB. A partition in a microprocessor architecture is employed. A virtual page number is selected. A stored LPID indicia corresponding to the selected page number is read from a TLB. The stored logical partition indicia from the TLB is compared to a logical partition indicia associated with the employed partition. If the stored logical partition indicia and the logical partition indicia associated with the employed partition match, a corresponding page table entry stored in the translation look-aside buffer is read. If they do not match, a page table entry from a page table entry source is retrieved and stored in the TLB. If a partition is to invalidate an entry in the TLB, a TLB entry command is generated and used to invalidate a memory entry.

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.
