I have the TLB entry for a particular address. This address has write-back attributes in both L1 cache and L2 cache. My queries are: 1> if L1 cache entry has write-back, can it be write-back in L2? 2> if L1 cache entry has write-back, then updated values will not be written into DDR until we apply flush. Does the same behaviour like DDR is applicable for L2 cache also?
