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?
