[Gems-users] Regarding dump-cache

[sparsh mittal ISU <sparsh@xxxxxxxxxxx>]

Hello All,

While using ruby, when I issue ruby0.dump-cache, 

I get 
.....
  Index: 12877 way: 2 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12877 way: 3 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12878 way: 0 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12878 way: 1 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12878 way: 2 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12878 way: 3 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12879 way: 0 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12879 way: 1 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12879 way: 2 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12879 way: 3 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12880 way: 0 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12880 way: 1 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12880 way: 2 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
  Index: 12880 way: 3 entry: [L1Cache_Entry: CacheState=I DataBlk= ] ]
..........................

On seeing the DataBlock.C file in ruby/common, the print function is the following:
void DataBlock::print(ostream& out) const
{
  int size = m_data.size();
  out<<size<<" "; //Added by me
  for (int i = 0; i < size; i+=4) {
  out<<"REACHED\t"; //Added by me
    out << hex << *((uint32*)(&(m_data[i]))) << " ";
  }
  out << dec << "]" << flush;
}

After these additions, when I run, I find that it is because the size is zero, so it never enters the for loop.
These means the Vector 
Vector<uint8> m_data;
always has size =0. 

Then how can we get or print the value of cache-data (or at least addresses stored in cache; so that one knows about the contents of the cache).
I would be thankful for the help.
