Issue with Obtaining Uncore Event Count Values on RPL Platform

[Arka2009]

Hi Team,

I'm currently working on obtaining the uncore event count values for my application's ROI using the command:

pcm-raw -el <evt file> -ep <perfmon dir> ...

I'm implementing this on two platforms, both running Linux:

1. Intel(R) Xeon(R) Gold 6326 CPU @ 2.90GHz (ICX)
2. 13th Gen Intel(R) Core(TM) i9-13900K (RPL)
   It works well on ICX but on RPL, I get the following error, shown below.

I've noticed that some files, specifically GenuineIntel-6-B7-1.json, are missing from https://github.com/intel/pcm/tree/master/src/PMURegisterDeclarations directory

However, the performance monitoring events for Alder Lake are present in the perfmon directory: https://github.com/intel/perfmon/tree/3fc7a87fde40817b521dbfb079da85b52a0cc96b. These events are also used by Raptor Lake. Any guidance on this discrepancy would be greatly appreciated.

Thanks
