IMX-GPU-VIV-5.0.11.p8.3

[richogrady]

On IMX6D hardware we have successfully implemented gpu-viv-bin-mx6s-3.0.101-4.1.1 binaries with freescale kernel 3.0.35 and the gpu examples work fine.  On the same hardware we implemented imx-gpu-viv-5.0.11.p8.3-hfp binaries with freescale kernel 4.1.15.  However none of the gpu examples work.  

For example if we run /opt/viv_samples/tiger/tiger we get:

   [galcore]: GPU[0] hang, automatic recovery.

   [galcore]: recovery done
   [galcore]: GPU[0] hang, automatic recovery.
   [galcore]: recovery done

   etc.

We are using the right examples.  

We are using hard float.  

What could be wrong?

We figured this out.  The device tree file had a dummy clock called out for the 3D shader.
