[meta-intel] CrownBay EMGD Performance for 1.4.2 in Rotation

[Chad Bishop]

Hello meta-intel Team,

I am writing to inquire about any known performance deficiencies when running with EMGD configured to rotate 90 degrees into portrait mode.

We have been (still) unable to rotate dynamically with xrandr and are thus configuring this statically at boot time with the xorg.conf.

With a non-compositing window manager we see the following average frame rates at 1024x768 :

Yocto - Landscape : 31.35
Yocto - Portrait : 16.35

I hate to draw comparisons, but our application (Qt 4.8.5 based) running in WES7 on the same hardware (Kontron COMe-mTT10) sees the following FPS impacts :

Windows - Landscape : 20.5
Windows - Portrait : 20.4

While this isn't blazing, it is steady and acceptable to the user.

It is a rather simple OpenGL scene.  We are using OpenGL and not OpenGL ES at the moment.

Thank you for your consideration of this question.

Best Regards,
Chad Bishop
