This is very interesting work for me!

I want to verify this feature with Arm CoreSight trace, I have one
question so that I have more direction for the tesing:

What's the bpf program you are suing for the testing? e.g. some
testing program under the kernel's folder $kernel/samples/bpf?
Or you uses perf command to launch bpf program?
