title: Using debug symbols with perf
body: <p>I monitor a process on a PowerPC system in order to extract performance information.
  How I can load the debug symbols of this process?
  I use the following command</p>
  
  <pre><code>perf record -g dwarf -p 4591
  </code></pre>
  
  <p>and I take an error that the "dwarf cannot be found (no such file or directory)"
  Could you please give me a hint how to load debug information about the functions that have been called when the report is generated?</p>
