How are cache latencies defined when using both ruby and opal?

The values inside the opal config file seems to be ignored, and there are several latency values when I look inside ruby's stats:

CACHE_RESPONSE_LATENCY: 12
L2_RESPONSE_LATENCY: 6
L1_RESPONSE_LATENCY: 3
L1_REQUEST_LATENCY: 2
L2_REQUEST_LATENCY: 4
L2_RECYCLE_LATENCY: 5

I am using the MOESI_CMP protocol with PT2PT links, and I wondering how I can modify the latencies when accessing local L1 and L2 caches?

I've looked through the archive, but I am still not clear how to change the latencies.
