Good intro.

After going through the Intel documentation it is clear that they have significantly more events to probe than AMD has with CodeAnalyst.

However, I was unable to find if you could trigger event counters on L1 store misses (either trigger directly or deduce them by inference from other counted events).

I think it is interesting to know just how common these are in order to infer how important the store-reordering of Core 2 is, - and also to infer how much the K8L, which will only have load-reordering, will lag behind.

We've discussed earlier that store misses carry as many data dependencies as loads do. I suspect store misses are significantly less frequent than load misses but have no way to get hard data, - at least from CodeAnalyst.

Cheers
Martin
