How to capture Mali-G52 GPU counters

As per the comment in that GitHub issue, gator.ko doesn't exist any more, it's been replaced with user-space only capture using gatord.  

• What version of Streamline are you using? 
• What version of the Mali driver are you using?
• Where does Streamline fail?

Cheers, 
Pete

Hi Peter

The streamline is installed associated with arm development studio. 

1. Arm Development Studio 2021.2 Linux 64bit with streamline

2. I don't know the driver version, I write the ubuntu20.04.img to microSD card.

3. streamline doesn't fail, I can see CPU information in the timeline chart.

Do you mean I should try to install the latest GPU driver?

Thanks

Ivan

Hi Ivan, 

• Have you selected any GPU counters in the Counter Configuration dialog (manually, or using a GPU template)?
• Can you run gatord with the "-v" option and share the log? (you can raise a support case or email mobilestudio <at> arm <dot> com if you can't share on the forums).

Cheers, 
Pete

Hi Peter

I have selected the GPU counters in the counter configuration dialog. 

after running gatord -v, I get the information of Streamline gatord version 780(Streamline v7.8)

Thanks

Ivan

./gatord -v

Streamline gatord version 780 (Streamline v7.8)

when using streamline to run glmark2-es2, i can capture following information.

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
