Hi, let me aks qustions.

I would like to compare program performance of our product between Broadwell-EP and Cascadelake-SP.

I used IDQ.EMPTY event to evaluate a situation of insufficient spply of instructions and processing efficiency for Broadwell-EP. However, that event seems to dissappear in CLX now. What pmc event in SKX/CLX is the replacement of IDQ.EMPTY event?  Can IDQ.MS_DSB_CYCLES  be a alternative event?

Thank you for your checking.
