Glmark2-es2 score for Mali T628 GPU and its dependency on Window Manager

Abha Jaswal

Hi ,

Recently I tried to run  the glmark2-es2 on Exynos 5422 Board of odroid.

The Mali Drivers version used was r4p1 for Mali T628 GPU and kernel version 3.19 rc1(same experiment was done with 3.10 kernel and 3.17 also)

For this I used Yocto distribution(dizzy 1.7.1) wih matchbox window manager first where glmark2-es2 score was very less - 18 FPS.

Then we changed the window manger to metacity in yocto and ran same gmlark2-es2 and score came out to be 65 FPS.

It was quite surprising as i thought the OpenEGL/Mali drivers performance depends on kernel configuration and performnace tunings done for Mali .

Is there any dependencies on window manger we chose also?

    Hi abha,

    Without investigating into either windowing manager, it is worth noting that to get full hardware accelerated performance, you will need to use one that supports OpenGL ES, and not OpenGL.

    If you use an OpenGL based one, it will have to fall back onto software rendering, for example using MESA. Whereas if it supports OpenGL ES, then Mali will be able to render it directly at full performance.
