title: How to determine Android GPU Clock?
body: <p>It is possible to dynamically query an Android device for the current CPU clock similar to what is mentioned in what follows.</p>
  
  <pre><code>adb shell "cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq"
  </code></pre>
  
  <p>However, it seems like there is not a similar option for GPU. I was wondering if there is a way, anything, to do the same for GPUs. Any help is greatly appreciated.</p>
  
  <p>(CPU/GPU frequencies are not good indicators of speed. I mainly need them for some study on DVFS)</p>
