ONLY FOR ADVANCED DEVELOPER !!!
I am pleased to announce that I already pushed my custom source code for VIVANTE GPU into my github : cm11-p6 !
With some tweaks you can successfully build your VIVANTE GPU libraries : libGAL.so, libEGL_VIVANTE.so, libGLESv1_CM_VIVANTE.so, libGLESv2_VIVANTE.so, libGLSLC.so, gralloc.k3v2oem1.so, copybit.k3v2oem1.so & hwcomposer.k3v2oem1.so, but unfortunately your P6 device will not boot because my source code for VIVANTE GPU must be updated/modified !
One of the best developers who could help us is: Recognized Developer : kholk !
I'm sorry, but at this time I can not help more, this wonderful community ....
Best regards !
