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!

    Hello Bodo,

    For streamline to work, you need two components on your system. The gator daemon and the gator driver.
    The gator driver is a kernel object, and in order to insmod on Android, you must have root permissions.
    As such, there is no current way to get streamline working on a none rooted Android device.

    Hope this clarifies things.
