How to capture Mali-G52 GPU counters

ivanzhang

I run gotard in ARM SoC board with Mali-G52 GPU and try to capture the GPU counters using the latest streamline.

The SoC board run Ubuntu OS. And I cannot get any GPU counters.

I search this issue and find that gotar.ko is needed. But the latest gator in github doesn't include the driver source code.

Please refer to github.com/.../19

Now how can I get the GPU counters?

    Hi Peter

    I found that there is no driver in my development board. but how can I install driver? my linux kernel version is 4.19.

    I can find kernel mode driver in arm. but where is user mode driver? Do I need to build it through mesa?

    Does arm development studio require specific linux kernel version? or driver version?

    Thanks

    Ivan

    Hi Ivan, 

    Mali drivers will need to come from your board supplier or chipset manufacturer. The open-source kernel mode driver on the Arm website is only the GPL kernel component. The user-space driver for the Arm driver is proprietary, and binaries must be provided by the platform vendor. Any version of the Arm driver will work with the Arm tools.

    Kind regards, 
    Pete
