In at least some embodiments, a cache memory of a data processing system receives a transactional memory access request including a target address and a priority of the requesting memory transaction. In response, transactional memory logic detects a conflict for the target address with a transaction footprint of an existing memory transaction and accesses a priority of the existing memory transaction. In response to detecting the conflict, the transactional memory logic resolves the conflict by causing the cache memory to fail the requesting or existing memory transaction based at least in part on their relative priorities. Resolving the conflict includes at least causing the cache memory to fail the existing memory transaction when the requesting memory transaction has a higher priority than the existing memory transaction, the transactional memory access request is a transactional load request, and the target address is within a store footprint of the existing memory transaction. |
