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 daisy5050:
    I'm trying get some Mali-400 profiling information from streamline.
    But my platform is Odroid-A and the Mali driver inside is legacy.
    Now I want to porting new Mali driver for it. But I'm not sure which version of the Mali driver is enough.
    Could you give me your Mali driver version number?
    Or your version is just download at Linaro web?
    Thank you very much.

    Hi ARM:
    I'm not sure daisy5050 can see this message or not.
    Could you help me to forward it, thank you.

    Hi Ching.


    Unfortunately, I don't have any idea about the version of Mali driver that I used.
    Odroid-A is based on Exynos4210.
    As I know,  the Android linux  kernel source for the Exynos4210 is from AP vendor like SAMSUNG.
    And a Mali driver inside the kernel is based on linaro.
    But we don't know whether a driver provider(or AP vendor) changed the Mali driver from linaro or not.
    And It should be noted that there is another Mali driver called User space Mali driver in Android source.
    It must be used as a pair with Kernel space Mali driver.

    You can ask ARM for more detailed information.


    Thanks,
    Daisy.
