title: Possible values for `uname -m`
body: <p>The <a href="http://man7.org/linux/man-pages/man1/uname.1.html" rel="noreferrer"><code>uname(1)</code></a> command-line utility has a <code>-m</code> option which prints the "machine hardware name".</p>
  
  <p>On Linux, this field comes from the <code>machine</code> member of <code>struct utsname</code>, as populated by the <a href="http://man7.org/linux/man-pages/man2/uname.2.html" rel="noreferrer"><code>uname(2)</code></a> system call.</p>
  
  <p>Many other language APIs return this information:</p>
  
  <ul>
  <li>Python: <a href="https://docs.python.org/3/library/os.html#os.uname" rel="noreferrer"><code>os.uname()</code></a> and <a href="https://docs.python.org/3/library/platform.html#platform.machine" rel="noreferrer"><code>platform.machine()</code></a></li>
  <li>PHP: <a href="http://php.net/manual/en/function.php-uname.php" rel="noreferrer"><code>php_uname()</code></a></li>
  </ul>
  
  <p><strong>What are the possible values for the "machine" field?</strong></p>
