Registering a user-handler in hardware for transactional memory event handling

摘要

A method and apparatus for registering a user-handler in hardware for transactional memory is herein described. A user-accessible register is to hold a reference to a transactional handler. An event register may also be provided to specify handler events, which may be done utilizing user-level software, privileged software, or by hardware. When an event is detected execution vectors to the transaction handler based on the reference to the transactional handler held in the user-accessible register. The transactional handler handles the event and then execution returns to normal flow.
