TDA4VM: TDA4VM: GPU HWR when upload 2D texture

Hello, 

I will review the logs.

Are you using the out-of-box SRV demo on Linux+RTOS (Vision Apps) SDK (here)?

Or is this with your custom application?

Thanks,
Sarabesh S.

Hello, Sarabesh

Thank you for your reply. I am using my own application instead of the SRV Demo in the SDK.

Hello, 

I did't get to this today. Will aim to get back to you tomorrow. Thanks

Hello, 

Apologies for the delay bandwidth has been limited. 

The best thing you can do to help isolate what the issue is on the GPU is capture a PVR Carbon. You can find how to do that here: 

 [FAQ] How can I analyze a GPU (Graphics Process Unit) driver or hardware issue? 

Hi Sarabesh

I have uploaded the pvrcbn file which recording about 50 frames of rendering data.

Since E2E indicated that pvrcbn was an invalid file type, I added the .zip extension to it.

iros_app_hvs.pvrcbn.zip

Hi Yun, I appreciate you sending this. I will give this IMG to review the OpenGL calls being made. 

Have you tried to replicate on a newer SDK/DDK. I see you're on DDK 23.2 and on the latest 11.x is using DDK 25.x.

Hi Sarabesh, Thank you for your reply.

We haven't tried reproducing the issue on the new SDK yet because switching SDKs is too much work. If the cause of HWR is a driver problem, is it possible to upgrade the GPU driver to a newer version without switching the SDK?

Hello, 

It is possible to do that backporting but I will first check with IMG if this issue that you're seeing is resolved in the later DDK versions.

Thanks,
Sarabesh S.
