How to run kernel functions in a separate core?


Hello Friends,
I am using Ubundu.

I want to know how to run kernel functions in a separate core?

I know about Taskset and it supports only for the application.

Do anybody know any command (or) have idea about how to do it?

Please help me

Thank you

Sure that's easy! edit your init scripts! Push everything to the second core by pushing init to the second core.
taskset would be the way to do it.

Hello,
Thank you for your reply.
I tried Taskset.
But it is working well only for the applications and not for the kernel functions!!!

Why would you want to do that ?.

Describe the problem (if you have one), not what you think you want to do.
Problem, not symptom(s).

That's the idea, push all the application to the second core and let the kernel have the first core to itself. Since it's currently not possible to relocate the kernel (as it has no PID and lives in ram) then the next logical thing to do is to move everything else out of the core the CPU is running on.
