Abstract
Examples described herein provide a computer-implemented method that includes generating an extended hot line table that tracks cross-core contended cache lines for multiple processors of a processing system based on cache requests, the extended hot line table storing at least metadata for a cross-core contended cache line. The method further includes polling, using firmware, the extended hot line table in each of the multiple processors of the processing system to identify contention information. The method further includes aggregating the contention information from each of the multiple processors to generate aggregated contention information. The method further includes processing subsequent cache requests using the aggregated contention information.
