Description
Hi thanks for the lib! When using eBPF mode, I wish to know which parts are system CPU and which are user CPU. The definition is just like the definition in `top` command.
Why I want this: I want to profile why the system CPU usage is high when looking at `top`.

Research direction
Start by locating the eBPF profiling path and how it currently records CPU samples; the issue does not name a file or test. Compare the desired attribution with the system and user CPU distinction reported by `top`, and consider the work done when profiles can distinguish those two categories.
