izardI just checked Andi Kleen's github repos for IPT, and it works perfectly on Joule. Unlike most experimental code, this one works out of the box. What I did not expect, I started full trace on stream, and stream results did not change!
It means that on Apollo Lake Atom platform, IPT is 0% intrusive - a very good sign!
P.S. Processor trace is the future of low level performance profiling.
