Linux build of the drivers gives

sep3_15, vtsspp, and PAX drivers.

I'm familiar with SEP.  

Is PAX something like "Power Analysis X" or something related to sampling power counters?  

What is VTSSPP an acronym for, what does this thing do, what's it's purpose?

Hello Ronald,

PAX is a driver layer that does arbitrage for SEP drivers. It allows to load and work with different SEP driver versions on one machine. Say you have VTune 2016 U2 and VTune 2017 Beta. The first one has sep 3.15 driver, the second has 4.0. After installation of both products and SEP drivers a VTune version will pick up proper driver through PAX arbitrage.

vtsspp is a collector that VTune uses to collect driver-based stack sampling (VT(une) S(tack) S(ampling) P(lus) P(lus)).

Thanks & Regards, Dmitry
