Abstract
A technique for operating a data processing system includes determining whether a cache line that is to be victimized from a cache includes high availability (HA) data that has not been logged. In response determining that the cache line that is to be victimized from the cache includes HA data that has not been logged, an address for the HA data is written to an HA dirty address data structure, e.g., a dirty address table (DAT), in a first memory via a first non-blocking channel. The cache line that is victimized from the cache is written to a second memory via a second non-blocking channel.
