Getting ARM Streamline to work with Samsung S2

Hi,

we have performance issues with Mali400 GPU's and need to track them down.

The ARM Streamline tool seems to be very useful for that.

We are using a Samsung S2 (GT I9100) to check here.

If I do the 'adb forward tcp:8080 tcp:8080' and try to connect with Streamline to localhost then I'll get a message: "Unable to receive data from the gator daemon .... ".
Obviously some gator process is missing (checked processes with ps and it's not listed there).

After doing some research, all I found is intructions on how to compile a kernel with a gator module.

I'm developing on a Windows 7 machine.
Even if I would fight through this, there is a step following that needs to start this gator with root rights.

Since I'm using a customer device I don't have root rights and I don't like to root it (let alone the illegal feel of it..).

So my final question is: is this the way? Or did I miss something?


Thanks in advance!

    We have a problem getting the Samsung Kernel to work.

    * Tried it with and without the necessary settings for the gator.ko.
    * Tried different toolchains
    -> But everytime I flash the kernel on the device (per Odin), the device shows the initial screen (device name + number and those yellow warning sign), goes black, shows this screen again .. and this is looping ..

    I assume, the kernel tries to boot, but something goes wrong.

    Tried another Custom Kernel for the I9100 (siyah_s2..) and this runs perfectly.

    Loaded the source of some Choon Kernel for the I9100, the build script runs smoothy, but flashed on the device, the Kernel has the same problems as the original Samsung code.

    Do you have any advice on this?
