摘要： Storing translation lookaside buffer (TLB) entries are in a TLB1 at the processor. The TLB1 includes entries associated with main storage accesses of programs executing in a guest mode in a current zone and entries associated with main storage accesses of firmware executing in a host mode. A quiesce interruption request is received at the processor that includes a requesting zone indicator. The processor is either executing in the host mode and has no zone or in the guest mode with the current zone. The requesting zone indicator and the contents of a programmable filtering register that indicates exceptions to filtering performed by the processor is used to determine if filtering should be performed. The quiesce interruption request may be filtered based on the requesting zone indicator even after the mode switches from the guest mode to the host mode.

摘要： A facility is provided for processing to distinguish between a full conventional (or total system) quiesce request within a logically partitioned computer system, which requires all processors of the computer system to remain quiesced for the duration of the quiesce-related operation, and a new early-release conventional quiesce request, which is associated with fast-quiesce request utilization. In accordance with the facility, once all processors have quiesced responsive to a pending quiesce request sequence, the processors are allowed to block early-release conventional quiesce interrupts and to continue processing if there is no total system quiesce request in the pending quiesce request sequence.

摘要： An embodiment of the invention is a processor for providing simultaneous access to the same data for a plurality of requests. The processor includes cache storage having an address sliced directory lookup structure. A same line detection unit receives a plurality of first instruction fields and a plurality of second instruction fields. The same line detection unit generates a same line signal in response to the first instruction fields and the second instruction fields. The cache storage simultaneously reads data from a single line in the cache storage in response to the same line signal.

摘要： A system, method, and computer program product for enhancing timeliness of cache memory prefetching in a processing system are provided. The system includes a stride pattern detector to detect a stride pattern for a stride size in an amount of bytes as a difference between successive cache accesses. The system also includes a confidence counter. The system further includes eager prefetching control logic for performing a method when the stride size is less than a cache line size. The method includes adjusting the confidence counter in response to the stride pattern detector detecting the stride pattern, comparing the confidence counter to a confidence threshold, and requesting a cache prefetch in response to the confidence counter reaching the confidence threshold. The system may also include selection logic to select between the eager prefetching control logic and standard stride prefetching control logic.

摘要： A method, system, and computer program product for cross-invalidation handling in a multi-level private cache are provided. The system includes a processor. The processor includes a fetch address register logic in communication with a level 1 data cache, a level 1 instruction cache, a level 2 cache, and a higher level cache. The processor also includes a set of cross-invalidate snapshot counter implemented in the fetch address register. Each cross-invalidate snapshot counter tracks an amount of pending higher level cross-invalidations received before new data for the corresponding cache miss is returned from the higher-level cache. The processor also includes logic executing on the fetch address register for handling level 1 data cache misses and interfacing with the level 2 cache. In response to the new data, and upon determining that older cross-invalidations are pending, the new data is prevented from being used by the processor.
