title: Can perf display raw sample counts?
body: <p>I'd like <a href="https://perf.wiki.kernel.org/index.php/Main_Page" rel="noreferrer">perf</a> to output raw sample counts rather than percentages.  This is useful for determining whether I've sped up a function I'm trying to optimize.</p>
  
  <p>To be clear, I'd like to do something like</p>
  
  <pre><code>perf record ./a.out
  perf report
  </code></pre>
  
  <p>and see how many times perf sampled each function in a.out.</p>
  
  <p>Shark can do this on Mac, as can (I believe) <a href="http://msdn.microsoft.com/en-us/performance/default.aspx" rel="noreferrer">Xperf</a>.  Is this possible on Linux with perf?</p>
