Abstract
A device is connected via a coherence interconnect to a CPU with a cache. The device monitors cache coherence events via the coherence interconnect, where the cache coherence events relate to the cache of the CPU. The device also includes a buffer that can contain representations, such as addresses, of cache lines. If a coherence event occurs on the coherence interconnect indicating that a cache line in the CPU's cache is dirty, then the device is configured to add an entry to the buffer to record the dirty cache line.
