Abstract:
A method including: receiving multiple local requests to access the cache line; inserting, into an address chain, multiple entries corresponding to the multiple local requests; identifying a first entry at a head of the address chain; initiating, in response to identifying the first entry and in response to the first entry corresponding to a request to own the cache line, a traversal of the address chain; setting, during the traversal of the address chain, a state element identified in a second entry; receiving a foreign request to access the cache line; inserting, in response to setting the state element, a third entry corresponding to the foreign request into the address chain after the second entry; and relinquishing, in response to inserting the third entry after the second entry in the address chain, the cache line to a foreign thread after executing the multiple local requests.
