Hi all,

I am using PEBS along with the load latency facility as described in the chapter 18.7.1.2 of the SDM. I always thought that this feature only allowed to sample memory loads accesses coming from data accesses and not code. I am today getting results that may indicate that's not true. Before deeging into this results, and because I am almost sure that the answer is no, I am asking it here: does Intel PEBS + load latency facility samples memory accesses coming from the instruction fetcher ?

Regards,
