[meta-freescale] linux-imx 4.9 EGLFS support

[Daniel Ammann]

Hi.

We're working on a imx6q-sabresd derived custom board. Our qt5 application uses
the eglfs backend. We're using linux-imx from meta-freescale (rocko) plus
kernel-module-imx-gpu-viv_5.0.11.p8.6+fslc.bb. The kernel module isn't
compiling which can be fixed by using 3b9e057f29853fd29364aa666328a92b807007d7.
It doesn't work though, eglinfo-fb errors out ("Could not obtain EGL display:
EGL failed to allocate resources for the requested operation."). It appears
that the work porting to 4.9 is not complete yet and more changes are
necessary. Does anybody have some pointers how to get eglfs working with 4.9?

Thanks,
Daniel

The 4.9 kernel is intended to be used with newer Vivante drivers; did
you consider using Etnaviv with 4.14? We have been using it with
customers with great success.

I am facing the same problem. I am trying to move my BSP to rocko. I ported
my custom kernel patches to the LTS 4.9 kernel and I would like to use the
LTS 5.9 Qt. What are the newer Vivante driver versions? It looks like in
rocko the imx-gpu-viv is 5.0.11.

Thanks,
Jeff

The newest is 4.9.123 which uses 6.0.
