Hi!
Now I have profling environment for Mali-400MP GPU with DS-5 Streamline.
But I don't have any document for GPU.
I found some doc. that was..

- using_arm_streamline.pdf
- mali_optimization_guid.pdf
- mali_gpu_developer_tools_overview.pdf... etc..

I couldn't find any specific explanation for counters of  Mali GPU. except for counter GPU activity( but I am still confused...)
So. I am asking you for some detailed document about Mali GPU profiling, If you can.
Now I have some profiling result, But I can't do anything..
Please let me make some progress...

Thank you
Daisy.

    Hi Chris,

    First of all, thank you for your quick response.

    Here is a doc. named "using_arm_streamline.pdf"
    http://infocenter.arm.com/help/topic/com.arm.doc.dui0482j/DUI0482J_using_arm_streamline.pdf

    My unresolved part  is "5.2.3 Mali-specific events"
    And I also checked "Mali GPU Application Optimization Guide"

    For example,
    "Active cycles"
    "Active cycles, vertex shader"
    "Active cycles, PLBU geometry processing" etc.. for Geometry processor.

    and
    " Active clock cycles"
    " Stall cycles PolygonListReader"
    "Pipeline bubbles cycle count" etc..  for Fragment processor.

    I couldn't find these counters in "Mali GPU Application Optimization Guide".and also anywhere.
    where can I find detailed information for it?

    Please let me know.

    Thank you.
    Daisy.
