Please look at the clib_calljmp(...) call in src/vlib/unix/main.c. It calls the function "thread0" on the first allocated thread stack. All of the other calls are similar.

As you mentioned function f, could you please tell for which function respected stack is created and what is that function f is responsible for?

Switching stacks involves saving, restoring, and avoiding damage to registers. The file is written in multiple assembly languages. If you have specific questions, I'm willing to take a shot at answering them. You'll need to look at instruction set reference documents and compiler ABI documents to fully understand each implementation. If you're not experienced with assembly language programming, I'd be tempted to steer clear. Stipulate that the code works, and move on... Thanks...
