Mali Graphics Debugger - "No trace data to display"

Rafael over 10 years ago

I can't get the MGD to work. Here's my configuration:

Client: Nexus 10 rooted, running Android 4.4.2

Host: Macbook Air running Mac OS 10.8.5

MGD: Version: 1.2.1.97319195

I followed the Target Installation instructions in the manual. When I try to start the MGD shell executable in the GUI folder I get a dialogbox saying: "Alert. The Mgd executable launcher was unable to locate its companion library" and I can click OK and exit.

Starting the mgd.app file from the Finder via double-click seems to be working fine though, the Mali Graphics Debugger window appears without any error message.

I can launch the mgddeamon on my N10 and connect to it from the GUI. On the command line I get:

...

Daemon is version: A006

Waiting for an interceptor to connect...

Waiting for a connection from the host on port 5002...

Host connected.

However, nothing happens in the main GUI window. The "statistics" are all 0, the main window keeps displaying "no trace data to display". Can somebody help me get this this going?

Thanks.

Hi rsp,
There is a known issue with KitKat currently which means MGD does not support it at present. The way that libraries are loaded has changed, with the dalvik vm now loading all graphics libraries instead of each process loading them independently. A fix for this issue will be rolled out into the next release. Assuming you were running a supported version of Android, you would have to start an application after starting mgddaemon for any trace to be captured. Applications started before running mgddaemon will not be traced.
Hope this helps,
Chris

Hi rsp,
Based on past performance, estimate end of Q1 for sure, likely before.
Thanks,
Chris

Hi rsp,
I thought I'd just let you know that we just published a new version of the Mali Graphics Debugger to include support for Android KitKat, in response to requests from our partners and friends on these forums. You can dowload it now from Mali Graphics Debugger « Mali Developer Center. Give it a go and let us know what you think.
Ta,
Mark
