Vikas,

Hi Neena,

Do you know which version of gpu kernel driver I need to use with imx-gpu-viv_5.0.11.p4.5-hfp? As  this imx-gpu-viv_5.0.11.p4.5-hfp user driver with gpu kernel driver from L3.14.28_1.0.0 GA seems to have the issue I mentioned?

It seems imx-gpu-viv_5.0.11.p4.4-hfp user driver with L3.14.28_1.0.0 GA works fine.

Vikash

Hi Prabhu,

I am currently trying with weston 1.6.0 and imx-gpu-viv_5.0.11.p4.5-hfp. With these all the application working except Qt example application from opengl folder. it is giving me following segmentation fault. Could you please provide your inputs  on this issue (https://community.freescale.com/message/573665#573665 )?

As I think,  I will hit the same issue with weston 1.8.0 and imx-gpu-viv_5.0.11.p4.5-hfp.

The wayland-EGL drivers capable of running framebuffer tests also.
Can you please make sure GPU sample apps available in #/opt/viv_samples/vdk/tutorial3_es20?

Yes, I also think that. I will give a try as time permits.

Do you mean the in-built "galcore" driver with "imx-gpu-viv_5.0.11.p7.1-hfp" here?

Thanks for adding these guys.
