Measuring latency on Snapdragon devices

Hi all,

In many reviews, deep dives and articles on ARM devices, I see a sweep of working set vs latency to determine cache sizes. Sometimes this is also working set vs BW. I roughly know (via simpleperf on android) how to determine the BW of a compute task but does anyone know how to measure either sampled or avg memory latency on ARM/Snapdragon devices? I looked at the perf counters available and couldn't find them.

Thanks in advance!
