Abstract
In an embodiment, a processor for invalidating cache entries comprises: at least one processing unit; a processor cache; and direct cache unit. The direct cache unit is to receive, from a first device, a direct read request for data in a first cache entry in the processor cache; determine whether the direct read request is an invalidating read request; in response to a determination that the direct read request is an invalidating read request: send the data in the first cache entry directly from the processor cache to the first device without accessing a main memory; and invalidate the first cache entry in the processor cache. Other embodiments are described and claimed.
