Part Number: TDA4VM

Hello Expert

LINUX

gpu version is 1.13.5776728

SDK 7.2

when we used TDA4 to render, there was a phenomenon of stutter, and it took about 5 seconds to output a frame of image. We got the log to help analyze it.thanks.pvrlogdump_2312121849.txt.gz

Li,

Thanks for sharing this issue. We have a few fixes to the driver since SDK 7.2, so this issue is potentially fixed by some of the patches we have.

Can you please make sure that you are using the a-type patch mentioned in this FAQ to ensure you are not seeing GPU hardware-recoveries related to that issue:

Erick.

The relevant patch has been installed, this is an occasional event, currently only see a case, render a frame time reached 500 seconds, restart the problem did not repeat, grab the log is to get a root cause whether there is a way to avoid such problems.

Li,

Thanks, the event happens when the GPU finds an issue while it is processing. These can be bugs in the driver or hardware.

1) If it is a unique or new bug, that can be fixed, but requires a good reproducibility. We will need to go back and forth with acquiring debug logs and providing patches.

2) We have some bug fixes that we've applied to the GPU drivers. Perhaps taking the latest GPU drivers with our latest known patches can help.

Please let me know how you would like to proceed.

Regards,

Erick
