Hi 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?
