Abstract
Performing a cache-based trace recording using cache coherence protocol (CCP) data. Embodiments detect that an operation that causes an interaction between a cache line and a backing store has occurred, that logging is enabled for a processing unit that caused the operation, that the cache line is a participant in logging, and that the CCP indicates that there is data to be logged to a trace. Embodiments then cause that data to be logged to the trace, which data is usable to replay the operation.
