[gem5-users] LRU insertion policy

[Sreya Sringa via gem5-users]

Somebody please tell me how do i implement LRU insertion policy.
Here is what i did.I lru.cc i  commented some of the lines.
LRU::accessBlock(Addr addr, bool is_secure, Cycles &lat, int master_id)
{
    BlkType *blk = BaseSetAssoc::accessBlock(addr, is_secure, lat,
master_id);

   // if (blk != NULL) {
        // move this block to head of the MRU list
      //  sets[blk->set].moveToHead(blk);
        //DPRINTF(CacheRepl, "set %x: moving blk %x (%s) to MRU\n",
       //         blk->set, regenerateBlkAddr(blk->tag, blk->set),
       //         is_secure ? "s" : "ns");
   // }

  //  return blk;
}

void
LRU::insertBlock(PacketPtr pkt, BlkType *blk)
{
    BaseSetAssoc::insertBlock(pkt, blk);

    int set = extractSet(pkt->getAddr());
   // sets[set].moveToHead(blk);
}

i.e I commented the move to head instructions. But still i get the miss
rate same as that of lru. Please suggest me how do i do that.
