enqueueNextFetchRequest()

void gem5::ruby::CacheRecorder::enqueueNextFetchRequest

(

)

Function for fetching warming up the memory and the caches.

It goes through the recorded contents of the caches, as available in the checkpoint and issues fetch requests. Except for the first one, a fetch request is issued only after the previous one has completed. It should be possible to use this with any protocol.

enqueueNextFlushRequest()

void gem5::ruby::CacheRecorder::enqueueNextFlushRequest

(

)

Function for flushing the memory contents of the caches to the main memory.

It goes through the recorded contents of the caches, and issues flush requests. Except for the first one, a flush request is issued only after the previous one has completed. This currently requires use of MOESI Hammer protocol since only that protocol supports flush requests.
