GPU Memory / Max Resolution in Linux 3.10.53

Hello experts,


On my custom iMX6DL board, I have a low resolution LCD (320x240) connected over 24-bit parallel bus.

The fb is configured correctly, and I can see images properly.


I am also able to get the GPU to run when using fsl-image-qt5-fb-imx6qdlsolo rootfs.

(Although, some GPU demos get make the device halt).


Some of the demos seem to be trying to allocate 1920x1080 resolution, or complaining that default resolution was not set.

Question #1 -- Is there a way to configure the GPU for the default output resolution?


Question #2 -- Since our display is very small, how can I reduce the GPU driver memory consumption?

(In 3.0.35 this was easy... but in 3.10.53, I can't find where to do this).
