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： Managing computer memory in a computer with dynamic logical partitioning that operates transparently with respect to operating systems in logical partitions. Exemplary methods, systems, and products are described for managing computer memory in a computer with dynamic logical partitioning that include copying by a hypervisor, from page frames in one logical memory block (“LMB”) of a logical partition (“LPAR”) to page frames outside the LMB, contents of page frames having page frame numbers in a page table for an operating system in the LPAR. Embodiments typically include storing new page frame numbers in the page table, including storing by the hypervisor, for each page frame whose contents are copied, a new page frame number that identifies the page frame to which contents are copied. In typical embodiments, copying contents of page frames and storing new page frame numbers are carried out transparently with respect to the operating system.

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。
