EGLContext issue in P9.0.0_1.0.0-ga for i.MX 8M Quad

[igrik]

Dear community,

I am working on Android 9 for a custom board based on the imx8mq design (HDMI connection). U-boot and kernel seem to load fine. I also get the Android to boot up and load proprietary Vivante libraries. Unfortunately, as soon as the surfaceflinger tries to create a EGLContext, the process crashes with EGL_BAD_ALLOC. Did I miss some kind of additional configuration in Android/Linux kernel?

Kernel version

4.9.51

Hi igrik,

In Android layer, we have the reference code to alloc aligned memory buffer for GPU, since you are using this, you need implement such align by yourself, from Android, the align code can be found in function alloc().

Regards

[igrik]

I found some allocation-related definitions in imx8m/evk_8mq/BoardConfig.mk

USE_ION_ALLOCATOR := true
USE_GPU_ALLOCATOR := false

They are only used in vendor/nxp/imx-vpu-cnm, which seems not relevant for imx8mq, as it uses vendor/nxp/imx-vpu-hantro.

I have also checked projects in vendor/nxp-opensource/imx/display: display, gralloc_v3 and hwcomposer_v20. Gralloc and hwcomposer are loaded correctly and the display module does provide an alloc function. However, this function isn't called before the crash occurs.

Bio_TICFSL‌, do you have an idea which module is the right one for me to adapt? I didn't find any documentation on this.

[Bio_TICFSL]

"Android\hardware\imx\mx6\libgralloc_wrapper\BufferManager.cpp" is from Android, the align code.

[igrik]

Thanks again,

Unfortunately, there is no such project in the Android 9 source tree for imx8mq. I didn't find any files with this or similar name or a gralloc-related project :smileysad:

Bio_TICFSL‌, any ideas? I will check if I can add this project manually to my source tree.

Hi Bio_TICFSL‌,

Thank you very much for the fast response!

we have the reference code to alloc aligned memory buffer for GPU

Do you mean, there is already an existing reference implementation somewhere, which has to be extended for custom board designs? Could you please point me to the project or file where this is used / has to be implemented (like kernel, gralloc, native frameworks, etc)? Probably there are many functions called alloc in the Android workspace.

Regards,

igrik
