Check Mali GPU usage

Jungsik Im

Hi,

I am working on Nexus-10 about Android Renderscript
Is there anybody to tell me how I can see the usage of T604 Mali GPU?
Currently, only DS-5 is available to profile GPU ? or there is other tool?

Thank you in advance

    Hi ,
    I'm stuck with mali400 platform. i have ddk release r2p4 is it possible to profile the GPU with this release? do i need to move to r3p2?
    on r2p4 i only get the linux and cpu traces no GPU traces and my silicon vendor ( hardkernel/samsung) is not releasing yet the r3p2 ( samsung still has to deliver it)
    any way to get the figures of the gpu usage ?
    Thanks




    Hello nfstry,

    Streamline for Mali-400 is supported out of the box from r3p1 onward  Earlier versions (such as r2p4) require modifications to be made to the Mali DDK. This can involve both kernel side, and userspace side, modifications.
    The kernel side is easy to do as we give the sources for this on malidevelopers.arm.com, however userspace side is a different matter.
    Unless you have access to the Mali DDK, you will not be able to apply the necessary patches to the Mali userspace libraries.
    The option here would be to contact the silicon vendor of the device you are using, and to ask for a version of the Mali libraries that support streamline.
    However, if you do have access, then this is something we can help with, but should be dealt with via an ARM support case.

    Thank you for your query. I hope this answered your question.
