Does ebpf-go support BPF_PROG_TYPE_PERF_EVENT?

[caneatcansleep]

Hi, I want to know whether ebpf-go support BPF_PROG_TYPE_PERF_EVENT, currently the attachPerfEvent function only support Kprobe, TracePoint, and I did't find any cases or examples about BPF_PROG_TYPE_PERF_EVENT.

What is this program type used for? A grep through the kernel selftests turns up some things related to periodic perf events, but I don't really find any examples. There was a PR to add periodic events (#924) to the perf package, but we're not going to add those in the near future. We're considering spinning off the perf package into a separate repo to allow the community to broaden its scope a bit.

What is your use case?
