  • Publication number: 20070283102
    Abstract: Disclosed is an apparatus, method, and program product that provides atomic, multi-word load support without incurring additional memory utilization. A double-word is atomically loaded without the use of one or more additional fields and without a lock. An invalidity marker is used in connection with a cache miss time to ascertain whether a loaded double-word has been stored and loaded atomically, and is thus, valid.

  • Publication number: 20070208882
    Abstract: An operating system kernel includes an attach mechanism and a detach mechanism. In addition, processes are tagged with an access attribute identifying the process as either a client process or a server process. Based on the access attribute, the operating system kernel lays out the process local address space differently depending on whether the process is a client process or a server process. A server process can “attach” to a client process and reference all of the client process' local storage as though it were its own. The server process continues to reference its own process local storage, but in addition, it can reference the other storage, using the client process' local addresses. When access to the other storage is no longer needed, the server process can “detach” from the client process. Once detached, the other storage can no longer be referenced.

  • Publication number: 20070143565
    Abstract: 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.

  • Publication number: 20060253682
    Abstract: 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.

  • Publication number: 20060242442
    Abstract: 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.
