Vtune gets confusing results when collecting openmp benchmarks

I used type <uarch-exploration> to collect performance data of my openmp offload benchmarks.

In the bottom-up tab, I found the most hottest function is a kernel function with unknown name(from vmlinux). And when I expand it to see the caller, vtune shows no call stack information. See attached image.

I wonder how this happened and what does this mean. Could anyone give me some help?

you should check the call stack dialog when configure.
