  • Huawei P40 Pro

  Refer to the supported devices page for a full list of supported devices. 

Streamline 7.6

• Support for Mali-G68 and Mali-G78 GPUs.
• Symbols are now correctly reported from libraries mapped direct from an APK without extraction.
• Better handling of APKs attached to the analysis where multiple bitness library versions are found.
• Ability to provide a fixed point scale in the Streamline Annotations header.
• Fixed an issue with process/thread attribution in a multi-process/-thread SPE capture.
• Minor usability improvements to the Android connection view.
• New tutorial - Android performance triage with Streamline.

• The required syntax when providing a file containing command-line options to the pa command has changed. You must now use the equals sign (=) between the option name and its value instead of spaces, and each option must be given on a separate line in the file. Options which accept a string, such as --application-name no longer need to be enclosed within double quotes when they contain multiple words.
• The lwi_me.py script has undergone a number of usability improvements.
  • When running the script from the Arm Mobile Studio installation directory, there is no longer a need to specify the path to the gatord daemon, or the layer library file. The script will locate these files automatically.
  • The script assumes that your app is 64-bit by default. To profile a 32-bit app, specify the --32bit option when running the script.
  • The script assumes that your app uses OpenGL ES by default. To profile a Vulkan app, specify the --lwi-api=vulkan option when running the script.
    Refer to Get started with Performance Advisor for instructions on how to run the script, and The lwi_me.py script options in the Performance Advisor User Guide for details on all the command-line options.
• The core count of the GPU in the device is now exposed in reports.
• To aid writing parsers, JSON Schema definitions are now provided in the performance_advisor/json_schemas directory.
• Performance improvements to the charts in HTML reports.
• New tutorials:
  • Integrate Arm Mobile Studio with Unreal Engine.
  • Setting performance budgets with Performance Advisor.

Graphics Analyzer 5.8

• Support for tracing 32-bit applications on a 64-bit Android device.

Mali Offline Compiler 7.3

• No new changes in this release.
