Mali Graphics Debugger: Not getting trace data in GUI

Ed Webb

I am trying to trace the GPU activity on an unrooted Samsung S6 using Unity. I have added the libMGD.so to my application and it does appear in my .apk package. I have installed the MGDDaemon and this can see my application.

I start the MGDDaemon and the Mali Graphics Debugger application (Windows8).

Debug | "Connect to target" appears to work and launches a window titled "Capturing Target@/127.0.0.1:5002".

There is no message on the console and no other output appears.

From the MGDDaemon app on device, I select my application which launches.

There are still no traces appearing within the Windows MGD app.

MGD v 3.0.0.6d92cba7

android-non-root\arm\armeabi-v7a\libMGD.so  dated 05/08/2015 18:38

Are messages getting lost somewhere?

Thanks in advance,

Ed

    Unity uses C# for scripting, but as I see the library you provided is written in c++.

    In c#, there's a method to load a dll, which was previously compiled by C#, too (and therefore it can be built to any supported platform later).

    Or you can call a specific function from the pre-compiled library using [DllImport()]. But I don't know which functions are in this .so file, which of them I need to call and when.
