Abstract
According to one general aspect, a method may include receiving a request, from a non-central processor device that is configured to perform a direct memory access, to write data within a memory system at a memory address. The method may also include determining if a cache tag hit is generated, based upon the memory address, by a caching tier of the memory system that is closer, latency-wise, to a central processor than a coherent memory interconnect. The method may further include if the caching tier generated the cache tag hit, injecting the data into the caching tier.
