ABSTRACT:
This disclosure presents an architectural mechanism which allows a caching bridge to efficiently store data either inclusively or exclusively based upon information configured by an application. An INC bit is set for each access to a page table that indicates whether the data is shared or not shared by a LLC. This allows a multicore multiprocessor system to have a caching policy which enables use of the last level cache efficiently and results in improved performance of the multicore multiprocessor system.
