Subject: [PATCH 0/6] perf script: export sampled callchains to database
Date: Thu, 28 Apr 2016 01:19:05 -0700	[thread overview]
Message-ID: <1461831551-12213-1-git-send-email-cphlipot0@gmail.com> (raw)

This patch set contains a set of changes to allow the export of sampled
callchains, and to associate them with samples, via the Python db export
API and export-to-postgresql.py script.

Call path information is currently only available in the database when
call/return info is available, but not when doing normal sampling. These
changes make this information available for normal sampling runs as well.

Patches 2-6 are required to make this information available in the
database.

Patch 1 is needed to fix an existing issue where callchains are
processed incorrectly which can cause the other patches to export
incorrect call paths for a small percentage of samples 
(depending on the workload).

Chris Phlipot (6):
  perf tools: fix incorrect ordering of callchain entries
  perf tools: refractor code to move call path handling out of
    thread-stack
  perf script: enable db export to output sampled callchains
  perf script: add call path id to exported sample in db export
  perf script: expose usage of the callchain db export via the python
    api
  perf script: update export-to-postgresql to support callchain export
