Abstract
There is provided a method for detecting a conflict between a transaction and a TLB (Translation Lookaside Buffer) shootdown in a transactional memory in which a TLB shootdown operation message is received by a processor to invalidate at least one entry in a TLB of the processor corresponding to at least one page. The processor tracks pages touched by the transaction. The processor determines whether the received TLB shootdown operation message is associated with one of the touched pages. The processor aborts the transaction in response to determining that the received TLB shootdown operation message is associated with one of the touched pages.
