[EXTERNAL] Re: etnaviv : IMX6 Solo GPU Performance Issue With OpenGL ES-CM 1.1

Hi Christian,

I have placed the application here https://github.com/vishnumotghare/opengl  in tar format (application-opengl.tar.gz). Let me know if you face problem accessing it. 

One observation that when I run the application, top command shows that application uses 70-80 % of CPU, that is strange, It should be using GPU instead of CPU. Right?

I have also tried using modesetting driver and with that performance is even worse than armada.

>> When I ran the benchmark application on WinCE7 the performance looked good but with similar application on Linux gives 50 % reduction in performance.
