Introduction
This PR tries to improve the documentation of the BCC
Module'sAttachPerfEventmethod.It fills the documentation for all the arguments.
Why
Even though the underlying ecosystem leverage BCC, libbpf and perf event, it can be useful to understand the usage of the gobpf binding directly from it, without the need of cross reference between BCC, libbpf and Linux headers.
Additional context
The arguments match the ones of
perf_event_opensyscall andbpf_attach_perf_eventhelper.Also, related issue on general BCC: iovisor/bcc#1756.
