Perf record + report

shirl

Hello community,

I have a question about the representation of perf record; perf report for Linux.

I would like a detailed illustration of the function's workload.
Thereby I want to map the behavior of the function in subprocesses, i.e. I want to see how long a function lasts and how long it stays in subcategories.

Can anyone help me with this? How is that possible?

Thank you and best regards
