Subject: more perf breakage from sample identifier
Date: Thu, 05 Sep 2013 15:35:38 -0600	[thread overview]
Message-ID: <5228F92A.9020108@gmail.com> (raw)

Adrian:

'perf kvm stat live' command fails on Linus' latest tree:
$ perf kvm stat live
Failed to parse sample

git bisect points to:

75562573bab35b129cfd342fc2bcf89da84a6644 is the first bad commit
commit 75562573bab35b129cfd342fc2bcf89da84a6644
Author: Adrian Hunter <adrian.hunter@intel.com>
Date:   Tue Aug 27 11:23:09 2013 +0300

     perf tools: Add support for PERF_SAMPLE_IDENTIFIER

     Enable parsing of samples with sample format bit 
PERF_SAMPLE_IDENTIFIER.
     In addition, if the kernel supports it, prefer it to selecting
     PERF_SAMPLE_ID thereby allowing non-matching sample types.

perf_evlist__event2evsel() is failing. From what I can see the problem 
is that evlist->heads is not getting populated. This command does not 
read/write files but processes events as they come in. I have another 
similar command that is also breaking for the same reason.
