Hi Billie, Thanks for getting back to me! Many sources mentioned the same thing, but where do I find the code that supports this? I followed the comment here: https://github.com/torvalds/linux/blob/c527f5606aa545233a4d2c6d5c636ed82b863... to check all the following files: arch/x86/entry/entry_32.S arch/x86/entry/entry_64_compat.S arch/x86/entry/entry_64.S arch/x86/entry/entry.S But I don't see any code that is calling the schedule or __schedule function.

I vaguely recall the actual switch taking place at the end of an interrupt, and/or during the return from a syscall, or on explicit request (e.g. yield). Look at __schedule and context_switch functions.
