Subject: perf top using /proc/kcore
Date: Mon, 14 Oct 2013 23:09:35 -0300 [thread overview]
Message-ID: <20131015020935.GB30662@ghostprotocols.net> (raw)
Hi Adrian,
While testing 'perf top -U' to reply a message in another thread
I noticed that ksm symbols appeared as '[kernel]', and only when I tried
'perf top -U -v' to look at the DSO long name I noticed that it was...
/proc/kcore.
Question is: since we have access to /proc/modules, can't we
parse that, as when we have access to vmlinux, and recreate the mmaps,
etc, and see:
[module] symbol
Instead of grouping everything into a single [kernel] bucket?
- Arnaldo
