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 Yasir,

    Thanks for the extra information.  I've also seen the incompatible chart configuration message in the past but don't know what provokes it.  I'll ask the Streamline developers for information on this one, but be aware that they are in our Olympia office and so will not see the question until later...

    The build of gator.ko doesn't require the full driver source, just the definition of the linux tracepoints which the driver uses to notify hardware events to the system.  These should be restricted to the single header 'mali_linux_trace.h'.  You shouldn't need to rebuild the driver, provided that the version you have is r3p1 or better.  Earlier versions only had limited support for gator profiling.

    Hope this helps,
    Mark
