[PATCH 0/3] perf: callchain-specific annotation
From: Alexis Berlemont
Date: Mon Apr 17 2017 - 19:02:27 EST
Hi,
These patches are a proposal to fulfill the following point of perf's TODO list
(https://perf.wiki.kernel.org/index.php/Todo):
* What I want is that if I am on bar*(), it annotates bar*(), no samples just
the call site (obtained from the callchain) dissassembly. This is useful
because in many cases there maybe multiple call sites within a function and
there maybe inlines in between. Hard to track down if you cannot figure out
the surrounding addresses of the call site. (Request made by Stephane
Eranian).
These patches are still at an early stage:
* Per-callchain annotation is only available in perf-report;
* Tests were not performed on real-world applications but on small basic ones.
Alexis.
