etnaviv : IMX6 Solo GPU Performance Issue With OpenGL ES-CM 1.1

[Christian Gmeiner]

Hi Vishnu

> We have an IMX6 solo custom device running with WinCE7 & Linux on it
>
> We have developed a custom benchmark application using OpenGL ES-CM 1.1

Is it possible to share this test application?

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

> glmark2 which uses opengl 2.2 gives 80 % score. Can it be issue with OpenGl 1.1 ? Or X driver?
