Thank you for your emails.
I have perf tool in my machine.
I want to measure L1, L2 cache misses, TLB misses, Branch misprediction for
some part of the code. Is perf_events enough for it?
What is the cache-misses event in perf tool? Is it last level cache miss?
And how to calculate the L1, L2 data cache misses?
Is there any documentation for perf tool?
Please let me know if perf tool is good enough for my work.
Thank you.
Regards
Sagar
