Disable GPU on Apalis iMX6 under Windows Embedded Compact 2013

Hello.

Is it possible to disable the GPU on Apalis iMX6 for headless devices to lower the power consumption of the Module. Currently we are using Windows Embedded Compact 2013 witzh BSP Version 1.1.

Best regards,
Dirk

You should be able to disable it by changing those registry keys:

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\GCHAL]
    "Dll"="_libGALCore.dll"

[HKEY_LOCAL_MACHINE\Drivers\Display\Apalis]
"DisableGPUAcceleration"=dword:1

This will skip initialization of the 2D/3D GPU.
Current BSP does not support DVFS dynamic clock adjustment, so this may also increase power consumption.
