I found that when using bpf_program__attach_uprobe_opts, it can only set one PID. Unless set to -1, it indicates all processes. Is there a way to set multiple PIDs? Or can it only be achieved through map.

Reset to default 1

Indeed you cannot attach to multiple PIDs, you would have to add some logic in your eBPF program and exit early if you detect you are running for a unwanted PID.

It works that way because perf events work that way, see arguments to perf_event_open.
