FPS and few other capture data are not showing up on streamline for Vulkan builds

Hi Peter,

Thanks a bunch for the getting back. :) 
So do you suggest that we instrument the build so we can manually add the counters in rather than get those "automatically" from the interceptor?

Regards.

Does the Light Weight Interceptor for Performance Advisor in Mobile Studio 2020.2 give you what you need?

If it doesn't I'd like to know what's missing, but manual annotation with Streamline software counters is always available as a fallback.

Cheers, 

Pete

Oh! I am using the PA in Mobile Studio 2020.2. Sorry, I did not mention that earlier. :)
I don't see, Frame rate, Draw Calls, Indirect Draw Calls, Vertices and Renderpasses. They all show up as default on the OpenGL Build.

Regards.

Thanks for confirming, we'll take a look and double check what's implemented. 

One more check - what's the full command you are using for lwi_me.py?

The command needs to know to the API to set up the right interceptor - you'll need --lwi-api vulkan.

I was not using the --lwi-api vulkan option, thanks for pointing that out. :) 

I now also added the --lwi-vk-layer-lib-path in, as I am using Android 9, but I noticed that there was no libVkLayerLWI64.so file under the unrooted folder, so I used the libVkLayerLWI64.so file that was under the rooted folder. 

So my command now looks like this

python3 '/Applications/Arm_Mobile_Studio_2020.2/performance_advisor/lwi/helpers/lwi_me.py' --daemon '/Applications/Arm_Mobile_Studio_2020.2/streamline/bin/arm64/gatord' --lwi on --lwi-fps-threshold 10 --lwi-frame-gap 100 -M tag --lwi-mode tag --lwi-gles-layer-lib-path '/Applications/Arm_Mobile_Studio_2020.2/performance_advisor/lwi/target/android/arm/unrooted/arm64-v8a/libGLES_layer_lwi.so'  --lwi-out-dir /Users/rohanpattada/Delete55 --package com.test.test --lwi-fps-threshold 10 --lwi-frame-gap 100 -M tag --lwi-mode tag --lwi-api vulkan --lwi-vk-layer-lib-path /Applications/Arm_Mobile_Studio_2020.2/performance_advisor/lwi/target/android/arm/rooted/arm64-v8a/libVkLayerLWI64.so

I noticed that the Counters started showing up during the run, but only FPS seems to be returning values, the rest of the counters like Draw Calls, Indirect Draw Calls & Vertices... that reappeared are blank, has no values are being returned.

Checking with the team here, and FPS is all we expect to work for Vulkan at the moment. Some of the others can be made to work in future, but require us to efficiently handle some state tracking and caching for parts such as secondary command buffers. This is on the roadmap to add, but it's not there today.

Which of the missing parts do you view as particular priorities - we can try and tackle those first =)

Kind regards, 
Pete

Thanks for getting back and for all the help. :)

1. Draw Calls/Frame
2. Vertices/Frame
3. Indirect Draw Calls

Thanks again for the help.
