Abstract
Interconnect circuitry comprises: receiving interface circuitry configured to receive, from a metadata-transmitting caching agent, discard control metadata for a given cache line previously held in a private cache of the data-transmitting caching agent; and transmitting interface circuitry configured to transmit the discard control metadata for the given cache line to a metadata-receiving caching agent for caching in a private cache of the metadata-receiving caching agent. The discard control metadata indicating whether the given cache line is, or is eligible for becoming, a discardable cache line allowed to be discarded without data writeback even if the discardable cache line is dirty.
