[gem5-users] findBlockBySetAndWay(int set, int way) in LRU

[Muhammad Avais]

Dear all,

             I implemented function findBlockBySetAndWay(int set, int
way_no) function in lru.cc file, as it's parent class ()base_set_assoc.hh)
function can not be applied to LRU class.

Code is simple but it gives block with wrong way_no.

CacheBlk* LRU::findBlockBySetAndWay(int set, int way_no){
     for(int i=0; i<sets[set].assoc; i++){
if(sets[set].blks[i]->way == way_no){
     return sets[set].blks[i];
}
     }
     return nullptr;
}

It is very strange. Can anyone guide about mistake in code?

Many thanks,
Best Regards,
Avais
