Abstract
An apparatus for cache coherency between a device and a processor includes a buffer module that buffers data in a non-cache coherent space of an electronic device communicatively coupled to a processor. The apparatus includes an update module that updates at least one identifier with respect to the buffered data. The at least one identifier is stored in a cache coherent space of the electronic device. The apparatus includes a coherence notification module that notifies the processor of a cache incoherence. The cache incoherence indicates that the cache coherent space of the electronic device that includes the updated at least one identifier differs from a cache coherent space of the processor that includes a copy of the at least one identifier prior to the update.
