TDA4VM: [TDA4VM] How to measure GPU load on TDA4VM-SDKv7

Hello TI-san,

I'm trying to measure the load on my application.

It seems that CPU and DDR load can be measured by using the appPerfStatsPrintAll() function,

but GPU load measurement is not included in this function.

Please tell me how to measure the load of GPU on TDA4VM-SDKv7.

Best regards,

Hello Ishibashi-san,

For GPU load, you can use PVRTune. More details here:

Hello Hemant-san,

Is a command line tool like "pvrscope" on TDA2Px included in the TDA4VM-SDK?

If yes, please tell me how to use the command line.

Hello Yudai-san,

Imagination Technologies SDK provides PVRScopeStats that can be included in any application. More details here:

https://www.imaginationtech.com/blog/powervr-graphics-sdk-tools-explained-getting-started-pvrscopestats/

And here:

https://cdn.imgtec.com/sdk-documentation/PVRScope.User+Manual.Developer.pdf

This should help you write any application that can collect statistics from any application.

pvrscope in TDA2Px SDK is just an example application using the same:

https://git.ti.com/cgit/glsdk/example-applications/tree/cpuload-plugins/pvrscope.cpp?h=master

You should be able to build and use it on TDA4 but we have not tried this out. General recommendation is to use PVRTune as it is comprehensive in terms of profile data information.

Hope this helps.

Regards

Hemant
