I'm trying to get the imx-gpu-viv driver/libraries (5.0.11.p7.1) working 
on an imx6-based custom board running linux-imx 3.14 (imx_3.14.38_6qp_ga 

I was able to get gpu-viv-bin-mx6q successfully working with linux-imx 
3.10.  In both cases I'm testing using the /opt/viv_samples/tiger test 
utility.  On the 3.10 build it works okay, with 3.14 it rarely works, 
most of the time it outputs this:

root at imx6q-pbab01:/opt/viv_samples/tiger# ./tiger
[galcore]: GPU is not present.
[galcore]: GPU is not present.
id=53, a,b,g,r=0,8,8,8, d,s=16,0, AA=0,openvgbit=71
[galcore]: GPU[0] hang, automatic recovery.
[galcore]: recovery done

Does anyone know might cause this? (eg. differences between 3.10/3.14, 

It could be an issue my configuration, although the display does output 
the linux logo at boot, and the tiger demo will occasionally work.
