TDA4VE-Q1: TDA4 ECO PVR issues

Tahm,

Thanks for the thorough analysis.

Can you please provide how often this new error occurs? And on how many devices?

I'll take the logdump you provided and see if we have enough information on the error.

Thanks,

Erick

Hi, Erick,

Tahm,

Thank you for the details, I've recorded the logs and have sent them for analysis.

Meanwhile, I wanted to check your configuration:

Then I found a post that was helpful for debugging. I removed the patch I had previously apply() and followed the steps in the post to capture the log:

You mentioned that you removed the old QoS patch, did you also update the GPU UM libraries, and re-compile the GPU kernel driver with the latest patches?

This is important to check because the new test will ensure that everything is applied correctly. You should also be able to run the following command without any issues:

rgx_kicksync_test -ver -nc 16 -loop 100 -n 10000 -r -seed 81576

If that is true, then your configuration is in good shape and I will get back to you as soon as I hear back on the logs.

Erick

Hi, Erick,

Sorry for delay. Thanks for your reply.

My steps to apply the patches are as follows:
1.  git revert "HACK: server: Make CCB allocations incoherent"

2. Enable_cached_mappings_in_KM_on_ARM64_for_DDK_1.15

3. update the UM libs

 tar xfz ${PSDKL_PATH}/filesystem/patches/2577.latest-1.15-umlibs.tar.gz -C ${output_folder}/
cp ${output_folder}/latest-1.15-umlibs/j721s2/* ${output_rootfs_folder}/ -rf && sync

4. rebuild the gpu driver

There was an error when I run "rgx_kicksync_test -ver -nc 16 -loop 100 -n 10000 -r -seed 81576"

Hi, Erick,

Currently: I only applied one patch:

Tahm,

OK, something is not correct about the setup, since we get this error. Let me review your steps and see what could have gone wrong.

Thanks,

Erick

Hi, Erick,

Ok, Looking for your good news.

Tahm,

Seeing the same issues as you, looking into the KM and UM libraries to see which is the culprit. Let me try updating the libraries to see if there is a difference.

Thanks,

Erick
