I found this code is pretty hard to understand.

I have learned it for more than a week, but made little progress.

I measured the cross core IPC cost, and from the result, it looks like there is only two IPIs, at least for simple data-only IPC.

But I cannot make sure this based on the code.

Could you give me more hints about this?

Thanks so much,

Best

I'm still not fluent but 4 are too many.
