A processor includes a logic to determine an error condition reported in an error bank. The error bank is communicatively coupled to the processor and is associated with logical processors of the processor. The processor includes another logic to generate an interrupt indicating the error condition. The processor includes yet another logic to selectively send the interrupt to a single one of the logical processors associated with the error bank.

Instruction and logic for machine checking communication

In accordance with embodiments disclosed herein, there is provided systems and methods for allocating machine check architecture banks. The processing device includes a plurality of machine check architecture banks to communicate a machine check error. The processing also includes an allocator to allocate during runtime of the processor a target machine check architecture bank of the plurality of machine check architecture banks. The runtime of the processor is during an occurrence of the machine check error.

Allocating machine check architecture banks

A method and apparatus for adaptive multiple line prefetching. In one embodiment, the method includes the identification of a prefetch depth. As described herein, a prefetch depth may refer to a number of memory lines to be prefetched to temporary (cache) memory. Once the prefetch depth is identified, prefetching is performed according to the identified prefetch depth. During the prefetching, the prefetching is adjusted as changes in the prefetch depth are detected. Accordingly, the dynamic adaptive multi-line prefetching mechanism described herein promotes higher system performance by the use of a more efficient prefetching mechanism.

A method and apparatus for a microprocessor with a cache that has the advantages given by a victim cache without physically having a victim cache is disclosed. In one embodiment, a victim flag may be associated with each way in a set. At eviction time, the way whose victim flag is true may be evicted. However, the victim flag may be reset to false if a superceding request arrives for the cache line in that way. Another cache line in another way may then have its victim flag made true.
