Kernel mode processes

[mohammad aghamir]

I want to find the execution context of each process by looking at it proc
struct <https://people.freebsd.org/~meganm/data/tutorials/ddwg/ddwg63.html>.
There is a solution
<https://stackoverflow.com/questions/25253231/context-of-linux-kernel-threads>
in Linux which solve this by looking at thread_struct->sp(kernel stack
pointer).

Is there a similar solution or even better to finding process execution
context?

P.S.: I'm really sorry if this question is "how to" and if not considering
as technical one. I'm really sticking to this and not found any solutions.
I'm really appreciated if you guide me.
