Official Introducing System Metrics Mali package

Thanks very useful package

Adding GPU Utilisation metrics on graphs and in detailed view will be very appreciated as much as adding description in tooltip for every metric in detailed view

 

Wish we could use this! Do you know of any way to get these counters from Adreno GPUs?

 

Thank you for this!
It doesn't seem to work with my phone (probably it's the phone's fault, it's a Moto e4 and ARM Streamline reports that CONFIG_HW_PERF_EVENTS is not set and/or that the PMU isn't configured in the target device tree). I'm going to try rebuild the kernel (whenever I learn how to) (Edit: I enabled it and more stuff, but still didn't work) with CONFIG_HW_PERF_EVENTS set, but my feedback would be for the "Mail System Metrics" tab to report that the phone isn't compatible (specifying why is probably asking too much, and something that can be solved by the developer anyway) instead of showing all the stats at 0 (which could lead to confusion).

 

Hey @antonk-unity ,

First of all, thank you for making this package - so much profiling details is something one could only dream before!

But I couldn't get it working so far with my Mali-G76. More likely I'm missing something obvious, but this is what I see while profiling my Galaxy S10+ (Exynos 9820):



I have dev build, Frame Timing Stats option enabled and using package Version 1.0.0-pre.2 (pre.3 is not available in the latest public 2022.1.0b7).

I also don't see the User counters group in the Profiler Module Editor:



What could I miss while setting things up?..

P.S. tried to manually update up to the pre.3 and pre.5 versions - there were errors in console and no Mali System Metrics profiler module available at all in both cases (might be not compatible with 2022.1.0b7).

 

Thanks for taking a look, but no, not a single error in the Unity Console.
I've also checked adb logs and didn't find anything related. I've attached the adb logs here just in case.

Furthermore, I also tried to profile the same device from an entirely another PC but without luck as well - still nothing for the Mali System Metrics module so far.

Please let me know how can I debug it if possible to get more logs for you, I'll be glad to help.

 

I'm from the Arm team who work on the backend counter interface the Unity profiler is using. Thanks for reporting the issue. A couple of questions:

* Can you confirm the driver version in your device? (Open chrome://gpu and find GL_VERSION string in the table).
* Can you try the Streamline profiler in Arm Mobile Studio and see if that manages to collect any data?

Also, at the risk of sounding like an IT tech support, have you tried turning the device off and on again? The main causes of failure in the driver for this look related to the kernel driver being unable to allocate memory, so a reset may help (although I doubt it).

Kind regards,
Pete

 

Hey Pete,

Thank you for chiming in,

Sure here is my GL_VERSION from the device:

OpenGL ES 3.2 v1.r32p1-01bet2-mbs2v39_0.9832bf74fac3612104002d946600017d

I've tried, and it seems to work just fine:


While still nothing in the Unity Profiler's Mali System Metrics...

=D yeah, this is a good one actually, and I know a lot of cases which were fixed with rebooting a device, but not this time unfortunately: rebooting didn't help - still nothing in the profiler for the Mali module =/

 

I just tried to reproduce it with another device on the same SoC (SM-G970F with Exynos 9820 and Mali-G76) and it does reproduce for it as well.

 

Thanks for the extra info. If Streamline is working then the underlying mechanism isn't broken, so I just need to work out why the driver connection is being rejected for the backend library the Unity profiler is using.

Cheers,
Pete

 

Just let me know if I can help you with any further debugging, I'll be glad to help!

 

@antonk-unity

Thank you for releasing a new version!
I've just updated the package to 1.0.0 version at Unity 2021.2.0f1 and this is what I see every time when entering Play Mode (I didn't make a build or connected to the Android device yet after fresh Unity instance start):

Code (CSharp):

1. SystemMetricsMali: Initialization failed
2. UnityEngine.Debug:Log (object)
3. Unity.Profiling.SystemMetrics.SystemMetricsMali:InitializeSystemMetricsMali () (at Library/PackageCache/com.unity.profiling.systemmetrics.mali@1.0.0/Runtime/SystemMetricsMali.cs:307)

It does happen in Unity 2022.1.0b9 too.

Is it expected behavior?

Next thing I did:
- Opened project with older SMM package in Unity 2022.1.0b9
- Build and run on device
- Attach Profiler and start capture (saw empty Mali profiler module)
- Update SMM package
- saw numerous warnings in Console like this:

Code (CSharp):

1. SystemMetrics: Failed to get handle for 'GpuCycles' id, check that native plugin id match
2. UnityEngine.Debug:LogWarning (object)
3. Unity.Profiling.SystemMetrics.SystemMetricsLibHWCP:GetProfilerRecorderHandle (string) (at Library/PackageCache/com.unity.profiling.systemmetrics.mali@1.0.0/Runtime/SystemMetricsLibHWCP.cs:40)
4. Unity.Profiling.SystemMetrics.SystemMetricsMali:.ctor () (at Library/PackageCache/com.unity.profiling.systemmetrics.mali@1.0.0/Runtime/SystemMetricsMali.cs:325)
5. Unity.Profiling.SystemMetrics.SystemMetricsMali:.cctor () (at Library/PackageCache/com.unity.profiling.systemmetrics.mali@1.0.0/Runtime/SystemMetricsMali.cs:312)
6. Unity.Profiling.Editor.SystemMetrics.Mali.MaliProfilerModule:.cctor () (at Library/PackageCache/com.unity.profiling.systemmetrics.mali@1.0.0/Editor/ProfilerModule/MaliProfilerModule.cs:10)
7.  

closing with these errors:

Code (CSharp):

1. ArgumentException: ProfilerRecorderHandle is not initialized or is not available
2. Parameter name: handle
3. Unity.Profiling.LowLevel.Unsafe.ProfilerRecorderHandle.GetDescription (Unity.Profiling.LowLevel.Unsafe.ProfilerRecorderHandle handle) (at <b2c530e619ab42aeba489c5671c82671>:0)
4. Unity.Profiling.Editor.SystemMetrics.Mali.MaliProfilerModule.GetDescriptorProfilerCounterHandle (Unity.Profiling.LowLevel.Unsafe.ProfilerRecorderHandle handle) (at Library/PackageCache/com.unity.profiling.systemmetrics.mali@1.0.0/Editor/ProfilerModule/MaliProfilerModule.cs:56)
5. Unity.Profiling.Editor.SystemMetrics.Mali.MaliProfilerModule..cctor () (at Library/PackageCache/com.unity.profiling.systemmetrics.mali@1.0.0/Editor/ProfilerModule/MaliProfilerModule.cs:10)
6. Rethrow as TypeInitializationException: The type initializer for 'Unity.Profiling.Editor.SystemMetrics.Mali.MaliProfilerModule' threw an exception.
7.  
8. Unable to create Profiler module of type Unity.Profiling.Editor.SystemMetrics.Mali.MaliProfilerModule. The Profiler module 'Mali System Metrics' cannot have no chart counters.
9. UnityEditor.ProfilerWindow:OnEnable ()
10.  

And Mali module disappear from the Profiler entirely.
Looks like an edge case with updating from the specific version to the 1.0.0 which might reproduce when updating from 1.0.0 to the newer version.

Then I restarted Unity 2022.1.0b9, build&run with Auto-connect Profiler option enabled, and it worked fine, though it didn't show the graph until the profiler window resize.

Hope this feedback helps!

 

Hey there, using 1.01, in Unity 2021.3.0f1, on my Pixel 6 (Mali G78)

I get no data in my profiler. The Mali System Metrics profiler module appears, but no data comes through when profiling device.

Tried Vulkan and OpenGL. Is there something I am missing?

 

Same experience as codestage:

1. Profiler recording, but no data in the Mali System Metrics module (My profiler looks like their screenshot)
2. Streamline can grab data from the device just fine
3. I've tried on 2 different work stations, both same result.
4. No errors/warnings/logs

 

Tried this on my Galaxy 7 Edge with the same outcome. (sm-g935w8)

 

@antonk-unity Any plan to support Snapdragon in future release? Actually is that still possible to achieve since I dun have Mali GPU phone?

 

I use mail-G610, but i get not date in my profile

 

Hey , i use it to test in mail-G610, but it didn‘t support.I think you need to update the hwcpipe.so

 

Hi. Any new update?
