Struct linux_perf_event_reader::records::ThreadMap

pub struct ThreadMap<'a> { /* private fields */ }

A list of threads, usually without names.

It’s not clear to me what the point of this list is. It doesn’t even give you the pid of the process that each thread belongs to. And unless you use perf stat, it doesn’t seem to have thread names either.

So it seems like all the useful information is instead in the PERF_RECORD_COMM records which get synthesized at the start of a file for perf record -p <pid>. It seems you’re better of just reading those, instead of looking at the thread map.
