Measuring software prefetching on Haswell E5-2600 v3 machine


In our experiment, I want to measure software prefetches (through use of PREFETCHT0 instructions). I have went through the available counters for our machine Haswell E5-2600 v3(, we could not come across any counter which provides us statistics related to software prefetches. 

We want to check whether there are any other counters we might be missing. If not, whether there are any other counters, from which we could possibly derive stats from which we can make sensible inference on software prefetches. I have checked the forum for similar discussion, the only one close to what we need( does not seem to help us. 

If there are any other suggestions on techniques we might have overlooked, please point it out.
