crash in libEGL with 3.10.17 BSP and wayland

[andyyang]

Hi YixingKong

I run into the same issue at my i.MX6 device.

I want to run 3D application which is developed by EGL/OpenGLES through weston-launch, it failed because the graphics driver is not right.

I check the error log and find that software call api[eglGetDisplay] and stop the application.

So i suspect that the whether libEGL-wl.so would have some question or not??

I have some questions for help.

1.Is DRM  must for weston(compositor),how to setup DRM?

2.Does GPU kernel drvier consist of kernel/driver/gpu/Vivante(Vivante.ko??) and of kernel/driver/gpu/drm/Vivante(DRM_Vivante.ko)?

3.Does user side drvier consist of EGL/OpenGLES?

4.graphics architecture is Application⇒EGL/OpenGLES/⇒libDRM⇒DRM_Vivante.ko⇒Vivante.ko⇒VIV-GPU?

Hello Andy,

Do you already add the patches for the GPU,

i.MX 6 D/Q/DL/S/SL Linux 3.10.17_1.0.1 Patch Release?

Hi Jamesbone

Thank you very much for your reply.

I will try to add this patch.

Meanwhile,let me confirm something.

I want to run wayland/weston on MCIMX6Qx/GPU-VIV target.

So i have to setup user space driver and kernek driver for GPU-VIV.

How can i get the freescale official release of user space driver and kernek driver for GPU-VIV?

Best regards.

Hi Andy,

the error you faced is due different GPU and kernel version, they have to match. If you get the old driver and try on a new kernel it will fail, the vice-versa also.

which BSP you are going to use ? LTIB or YOCTO ? in both cases you need to include the gpu-viv-bin package (in package list)  and also the wayland.

it will only be possible to use different version if you rebuild the gpu source code, what I think this is not the case.

regards,

Andre

The previous DI had been closed for some time. To make thing simple, I branch your post into this one, and will try to find an engineer to help you.

Thanks,
