Top-Down microarchitectural analysis

Hi,

I was wondering if there are any documentations on how to analyze the ARM pipeline. I have access to thunderx2 nodes, and i'd like to make bottleneck analysis like can be done on intel chips.  i can get the formulas to get compute the different metrics for a skylake here https://github.com/andikleen/pmu-tools/blob/master/skl_client_ratios.py. i checked the regular arm docs, ARM Architecture Reference Manual ARMv8, for ARMv8-A architecture profile, and Programmer’s Guide for ARMv8-A and i did not find any information.

thanks,
