Abstract: A method, system and computer program product for processing in a multiprocessor data processing system are disclosed. The method includes, in response to executing a load-and-reserve instruction in a processor core, the processing core sending a load-and-reserve operation for an address to a lower level cache of a memory hierarchy, invalidating data for the address in a store-through upper level cache, and placing data returned from the lower level cache into the store-through upper level cache.

Abstract: A method which enables game developers to capture user actions and to automatically solicit user feedback as game events occur, so that game developers can then use this data to “tune” the game to improve a user's experience is disclosed herein. To develop game data, function calls and user inputs are recorded in a log file. Also, players can provide feedback on game play after predetermined events occur (e.g., player finishes level) or through a pause menu. By allowing a development team to better understand a user's experience in game play, the game can be tuned to improve the user's experience.
