摘要: Methods and apparatus relating to directory based coherency improve input/output write bandwidth in scalable systems are described. In one embodiment, a first agent receives request data from second via link logic causes the state an Input/Output Directory Cache (IODC) of agent. Additionally, send modified exclusive using back agent, while allowing remain cached exclusively also enabling deallocation IODC entry Other embodiments disclosed.
