A system and method have been provided for pushing cacheable control messages to a processor. The method accepts a first control message, identified as cacheable and addressed to a processor, from a peripheral device. The first control message is allocated into a cache that is associated with the processor, but not associated with the peripheral device. In response to a read-prompt the processor reads the first control message directly from the cache. The read-prompt can be a hardware interrupt generated by the peripheral device referencing the first control message. For example, the peripheral may determine that the first control message has been allocated into the cache and generate a hardware interrupt associated with the first control message. Then, the processor reads the first control message in response to the hardware interrupt read-prompt. Alternately, the read-prompt can be the processor polling the cache for pending control messages.
