Hi 👋

I am not sure that I use it right, I was not able to profile using these events:

I am on a M1 Pro machine using macOS 15.5.

I just wonder if these events are support on Apple Sillicon.

I'm very interested in this too. If not using Instruments, is there any other way to inspect CPU Caches, branch predictions, etc on Apple Silicon for performance-related work?
