Cannot get any papi events on my machine

[Vidush Singhal]

Hello,

I have an alderlake intel 12^th gen i7 12700K

I have been trying to install papi, however papi_component_avail shows me no perf_uncore events.
I tried to enable all options in the BIOS. In addition, perf uncore events on their own work.
I compiled the latest papi from git papi_avail shows me that 0 counters are available.

I have no idea how to get the counters working and any help would be much appreciated. 
Sincerely,

Vidush Singhal

Hello Vidush,

I believe that at this time there are no definitions for the PAPI predefined events on the alderlake architecture. However, you should still be able to access native events. It looks like from your papi_component_avail output, perf_event has identified 185 native events on your machine which can be added to EventSets and used with PAPI_start/PAPI_stop. Do you see these events listed properly when you run papi_native_avail?

Hi Willow,
Thanks for getting back to me.
I do see the native events, but I wasn't sure if I could access these in the C++ code.
Thanks,

Vidush
