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 Ching,

    We release the source code to the kernel space components of the driver stack under the GPL license on malideveloper.com, but the source code to the userspace libraries which expose the APIs such as GLES and EGL are only provided to silicon licensees, and as such are only available as prebuilt binaries from your vendor (HardKernel / Samsung in this case). In order to be able to collect streamline profiling data, the userspace libraries must be built to support it, so you will still need to ask your vendor for copies which support streamline profiling. I suggest approaching HardKernel via their forums as they should be able to provide these to you.

    Thanks,
    Chris
