I have a trouble with profiling my Unity project. (latest Unity 2019.2.12)
I'm failed to use Graphics Analyzer from latest Arm Mobile Studio to profile Vulkan-based Unity application. I have just create empty test scene, add Vulkan interceptor (as specified at https://developer.arm.com/docs/101545/0504/target-installation/android/unrooted-android/installation/installing-for-an-opengl-es-unity-application), build apk, install it on Samsung Galaxy S9 phone, run it and faced a crash. Its not shown in the traceable list in GA Daemon Application also.
At the same time GLES interception method worked as expected. Empty scene with GLES rendering API and libMGD.so interceptor lib have worked without crashes, listed in GA Daemon Application and sends data to host application (I have set Android API level to 25).
Maybe Vulkan interception lib embedding instruction lacks some important steps? Are there succesfull attempts to profile Unity Vulkan-based projects? What the steps I should take to provide more info to solve this problem?
Thanks in advance, Alex.
Some progress on this one, but the route to getting it working is a little different.
Note: Do not try to use the direct connection methods or the layer install methods in the table at the top of Connection dialog; they will try to use the Daemon APK, rather than the command line daemon, which no longer works with the new Android security model and will be removed in the next release.
adb push %LOCAL_LIB_NAME% /data/local/tmp/%LAYER_LIB_NAME%
adb shell run-as %APP_NAME% cp /data/local/tmp/%LAYER_LIB_NAME% .
adb shell run-as %APP_NAME% ls %LAYER_LIB_NAME%
adb shell settings put global enable_gpu_debug_layers 1
adb shell settings put global gpu_debug_app %APP_NAME%
adb shell settings put global gpu_debug_layers %LAYER_NAME%
python3 aga_me.py %APP_NAME%
Let us know how you get on, and sorry for the time it took for us to work this one out,
Sorry for the long response. Is this method applicable for rooted devices only? Because my device is not rooted :)
I have tried your script and I've tried to change lib path to unrooted/arm64-v8a/libAGA.so but with no luck. Script works good, install interceptor like:
rooted/arm64-v8a/libGLES_aga.so: 1 file pushed. 27.1 MB/s (10595792 bytes in 0.373s)libVkLayerAGA.so
unrooted/arm64-v8a/libAGA.so: 1 file pushed. 28.3 MB/s (10976752 bytes in 0.369s)libVkLayerAGA.so
But I cannot connect to deamon from Device Manager:
Connection refused when connecting to 127.0.0.1:5002.
Problem reading the trace version: 'Read timed out'.
How can I check that the deamon is working?
Thanks for you assistance!
No, this should work with non-rooted devices. Note that you definitely do want the "rooted" build of the interceptor - the unrooted one is designed for in-app symbol patching and will conflict with the Vulkan layer driver loader.
Also, the aga_me.py script will install the command line daemon, make sure that you don't have the Daemon APK installed (it doesn't work with the Android security model in latest Android devices, and will get removed in the next release).
In terms debugging, you should get some logging showing up in "adb logcat".
