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 caogao,

    As we do not support r2p4 drivers for GPU profiling, we cannot help with this.
    For official support, you would need to ask Samsung for updated drivers.

    I apologise we cannot help you further on this.

    Hi McGeagh,
    I'm having very similar problem too. I'm using an Origen Quad board which uses Samsung Exynos 4 with Mali-400MP GPU.
    The GPU driver provided by Samsung is pretty old (r2p4).
    At first I cannot build the gator module for Streamline GPU profiling because there is no "mali_linux_trace.h" in the Mali driver folder.
    Then I copied the file with the same name from a newer version to the driver folder. I could build and run it, but I cannot get GPU profiling. Instead I get these error message:


    [ 1637.498392] gator: mali online _mali_profiling_set_event symbol not found
    [ 1637.507603] gator: mali online _mali_osk_fb_control_set symbol not found
    [ 1637.512948] gator: mali online _mali_profiling_control symbol not found


    [size="2"]Is there any work around for this problem other than asking Samsung for a newer version of Mali driver?

    Thanks.[/size]
