Linux kernel thread

stackoverflow How to bind certain kernel threads to a given core?

Several kernel threads are tied to a specific core, in order to effect capabilities needed by the SMP infrastructure, such as synchronization, interrupt handling and so on. The kworker, migration and ksoftirqd threads, for example, usually have one instance per virtual processor (e.g. 8 threads on a 4-core 8-thread CPU).

You cannot (and should not be able to) move those threads - without them that processor would not be fully usable by the system any more.

Why exactly do you want to move those threads anyway?
