Subject: [PATCHSET 00/10] perf tools: Apply percent-limit to callchains (v2)
Date: Thu, 28 Jan 2016 00:40:47 +0900 [thread overview]
Message-ID: <1453909257-26015-1-git-send-email-namhyung@kernel.org> (raw)
Hello,
This patchset tries to implement percent limit to callchains which was
requested by Andi Kleen. For some reason, limiting callchains by
(overhead) percentage didn't work well. This patch fixes it and make
--percent-limit also works for callchains as well as hist entries.
* Changes from v1)
- fix insertion path instead of changing all UI code
- show percent value even on single path (if needed)
- change default callchain percent limit
This is available on 'perf/callchain-limit-v2' branch in my tree:
git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git
Any comments are welcome,
Thanks,
Namhyung
