Latest Vivante GPU binaries - imx6q

[EinarMar]

Hi

I was wondering if I could somewhere get a hold of the latest Vivante prebuilt hardfloat binaries ?

I have a custom iMX6q board and wanted to see if there were any newer binaries available then L3.0.35_4.1.0, see here: https://community.freescale.com/docs/DOC-95560

I have used this version with Qt5.2 and Qt5.3 some time ago but now I when I use it against Qt5.4 it crashes. My application is using the eglfs platform (No X or Wayland) and it crashes after trying to open /dev/fb0.

I decided to give a new version a try if it were available.

My goal is to run a Qt5.4 browser application that utilizes the 2D acceleration.

regards

Einar

I found what I was looking for here: http://repository.timesys.com/buildsources/g/gpu-viv-bin-mx6q/

Timesys is keeping a repo of prebuilt binaries and header files that follow the kernel versions issued by Freescale, the latest one being 3.10.17.

I downloaded the libraries and header files, recompiled Qt5 and things started to work-ish !!

I had a kernel panic which lead me to change the split ptlock in include/linux/mm_types.h as suggested in the patch here: https://lists.yoctoproject.org/pipermail/meta-freescale/2014-March/007816.html.

After that the graphics work fine and the accelerated examples provided both by Qt and Vivante are working fine, i.e. utilizing the GPU.

Hope this helps somebody.

Hi Einar

I think one can look at

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/log/?h=imx_3.10.31_1.1.0_beta

and post to meta-fsl-arm mailing list, so that someone familiar with latest drivers could

try to assist you.

Best regards
