Reduce/Disable GPU Memory

[jporembski]

I am running effectively a headless wandboard with Arch. It doesn't need to do anything other than handle SSH, apache, and a terminal as far as I am concerned.

I am relatively new to the Wandboard, but on Raspberry Pis it is pretty easy to reconfigure the memory utilization so the GPU has access to little-to-no memory. How can this be done on the Wandboard or in ArchLinux? It seems by default around 250MB is being dedicated to the GPU (I got this number from htop, which shows only 1750MB of RAM available)

Since this is going to have an apache web-server, I would like to give the CPU access to as much RAM as I possibly can. Any suggestions?

It might be configurable through your graphics drivers. Googling reveals a project called etnaviv, but I'm not sure what you are using exactly.

Worst case: memory aperture is set on boot by reading some hardware registers, and no-one knows where these lie. It might be better to ask on the Wandaboard forums.
