Calculating LLC MPKI

I am interested in calculating the LLC MPKI for RPL-S. 

And, as per my understanding, I should be using MEM_LOAD_RETIRED.LLC_MISS event. 

And the formula would be: 

LLC MPKI = MEM_LOAD_RETIRED.LLC_MISS/INST_RETIRED.ANY*1000.

Can you confirm if the above formula is, ok?

That formula looks correct if you want the load instructions from P-core that miss L3. The correct event name is MEM_LOAD_RETIRED.L3_MISS rather than MEM_LOAD_RETIRED.LLC_MISS.
