[gem5-users] when prefetcher is called?

[Mahmood Naderan]

Hi,
Just for a double check, is this statement true?

The prefetcher is called on of the following cases:
1- cache block is accesses
or
2- that block was a prefetched block
or
3- cache miss

I said that because of the following code.

if (satisfied) {
        if (prefetcher && (prefetchOnAccess || (blk &&
blk->wasPrefetched()))) {
            if (blk)
                blk->status &= ~BlkHWPrefetched;
            next_pf_time = prefetcher->notify(pkt, time);
        }
        ....
} else {
        // miss
        if (mshr) {
         .....
        } else {
            // no MSHR
             .....
            if (prefetcher) {
                next_pf_time = prefetcher->notify(pkt, time);
            }
        }
}


Thanks and sorry for taking up your time
