Mali G52 - Failed to create reader for mali GPU # 0

Qing Xia

Streamline version: Version 8.0.0, Build 20220217_150925 windows 64-bit.

Device: Mali G52(Bifrost - r21p0)  on Android.

If any GPU perf counters are selected from "Add counters from a template", the capture will not start with:  

If I capture without any mali counters selected, I can successfully get a capture(with only CPU info).

    Hi ; can you please provide a debug log from gatord. You can do so as follows:

    adb push <streamline-install>/bin/arm64/gatord /data/local/tmp/
    adb shell /data/local/tmp/gatord -d -S no -A find / 1> /data/local/tmp/gatord.log 2>&1

    < try counter configuration, you may need to use the TCP/Advanced view in Streamline rather than the Android view >

    < stop gatord with ctrl-c, once the above error message is seen >

    adb pull /data/local/tmp/gatord.log

    This file should help identify the reason for the failure.

    Thanks
    Ben

    Hi Ben,

    Thank you for your reply.

    I cannot find out how to upload the full log here. :( 

    I am posting what I think is relevant here:

    I hope this is enough for you to identify the reason. If not, I'll try somehow upload the full log.

    Just to confirm - have you tried power cycling the device? 

    Cheers,

    Tried reboot the device. Same problem.

    Thank you.
