What happens with L2 in this situation

If I have L1 100% Read only but L2 R/W I notice that it will write to L1 if the data modified is in L1 cache and that is fine and great. My question is that if that data is also In L2, does it update L2 also or does that get evicted from L2 and only returns to L2 if that data is read again?

Good question! If L2 is R/W, it will also update L2. If L2 is Read only, L2 will get evicted.

Thanks. What if free cache on written is selected? Will it mark the blocks in both L1 and L2 as standby or just L1?

This option applies to both L1 and L2.
