MALI-400 Driver Support Issue

Note: This was originally posted on 25th September 2012 at http://forums.arm.com

Hi,
I am working on Galaxy S3, Exynos quad-core, [font=sans-serif]1.4 GHz quad-core [/font]Cortex-A9 with MALI-400 MP.
The device is using Android Jelly Bean. Linux/arm version is Linux/arm 3.0.31 Kernel.
While using profiling (streamline) in DS-5, GPU snippets are not showing.
"Chart configuration is incompatible with this configuration is showing when GPU counters are selected.
Before that, I built gator.ko and gatord and copied them into same directory in target.
Using DS-5, I can get CPU performance counters but not GPU counters.
I even generated gator.ko with "GATOR_WITH_MALI_SUPPORT=MALI-400".
Can anyone kindly guide me about where are we missing something.
[size=2]Thanks a lot.[/size]
Yasir.

    Hi Medge,
    Thanks for your reply.
    From "Snippets' in DS-5, we can select GPU Mali. All of them have got all or partial missing source data. For example,
    For snippet "Mali GPU Fragment Processor 0", missing data are "Active clock cycles" and "Vertices processed".
    For "Mali GPU Vertex Processor", missing data is "Vertices processed".
    For GPU Bandwidth Split" and "GPU Total Bandwidth", "System bus reads", "system bus write", "total bus reads, "total bus writes" are all missing.
    For "glDraw Arrays Statistics", missing source data is "Calls to glDraw Arrays" and "Calls to glDraw Elements".
    Once i also saw an error (?) explaining "The chart metrics does not map to individaul processor cores" for Mali GPU vertex processor.
    On the other hand, I am getting all counters related with CPU performance i.e. CPU activity, wait, instructions etc.
    Thanks for your effort.
    Yasir.
