Subject: Getting PMU stats on specific syscalls
Date: Tue, 9 Jan 2024 14:55:52 -0800	[thread overview]
Message-ID: <202401091452.B73E21B6C@keescook> (raw)

Hi,

I'd like to get PMU stats only on specific syscalls. I haven't been able
to figure this out. i.e. how do I run:

	perf stat -e some_syscall_name_here make -j128

I can't figure out how to limit collection to only time spent during the
syscall I'm interested in. I tried building synthetic events, but that
doesn't seem to work...

Thanks!

-Kees
