linux - How can we know the exact number of the hardware performance counters built-in CPU?

After I have done several reading on Hardware Performance Counter, I can claim that all of the Intel processors have supported with Hardware Performance Counter. So, In order to access these additional hardware registers ,i.e. hardware performance counters, I have used PAPI infrastructure frequently used to access and configure these counters.



When I used papi_avail utility program to report information about number hardware counters, unexpected value was viewed, i.e. with respect to Fig, number hardware counters : 0. Could it be?



With respect to my processors model (Intel core i7), I think this is incorrect value.



I really appreciate any help you can provide.
