<pre>Grab and install a kernel from <a href="http://cgit.freedesktop.org/~ickle/linux-2.6/">http://cgit.freedesktop.org/~ickle/linux-2.6/</a>
#master and build intel-gpu-tools/overlay/intel-gpu-overlay. Use SNA and run
the overlay (use "intel-gpu-overlay --position bottom-right" to place it
somewhere convenient). That should show the frequency and power consumption of
the GPU (along with usage and frames/30s) that will be interesting to correlate
with the periods of slow behaviour if there are no obvious errors in the log.</pre>
