[PATCHSET 00/12] perf tools: Apply percent-limit to callchains

From: Namhyung Kim
Date: Sun Jan 24 2016 - 08:54:45 EST


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.

This is available on 'perf/callchain-limit-v1' branch in my tree:


Any comments are welcome,
