Abstract
A coherent attached processor proxy (CAPP) that participates in coherence communication in a primary coherent system on behalf of an attached processor external to the primary coherent system tracks delivery of data to destinations in the primary coherent system via one or more entries in a data structure. Each of the one or more entries specifies with a destination tag a destination in the primary coherent system to which data is to be delivered from the attached processor. In response to initiation of recovery operations for the CAPP, the CAPP performs data recovery operations, including transmitting, to at least one destination indicated by the destination tag of one or more entries, an indication of a data error in data to be delivered to that destination from the attached processor.
