Arm Mobile Studio is a suite of performance analysis tools that enables Android application developers to detect performance bottlenecks in their software and rendering through analysis of performance counters and graphics API traces.

This release of Arm Mobile Studio includes:

• Streamline 7.2, to profile application performance.
• Performance Advisor 1.0, to generate at-a-glance application performance summary reports.
• Graphics Analyzer 5.5, to debugging graphics API usage.
• Mali Offline Compiler 7.1, to perform static analysis of GPU shader programs.

This is the first release of Performance Advisor, an data analysis tool that can post-process a Streamline data capture from a Mali system to provide an at-a-glance HTML report that summarizes the application performance characteristics and provides advice about where to optimize.

Feedback and support

For Arm Mobile Studio Starter Edition you can raise queries and support issues relating to both the tools and general performance analysis on the Arm Community website.

Known Issues

The following known issues are present in this release:

Graphics Analyzer

• MGD-4152: Linux build host tool GUI panels can fail to respond to mouse wheel events.
• MGD-3735: Debug frame capture views (overdraw map, shader map) can fail for Unity applications. 

Mali Offline Compiler

• OSC-485: Invoking malioc on macOS 10.15 (Catalina) returns the following security warning, because the binary is not in the ".app" format:
  
  "malioc" cannot be opened because the developer cannot be verified.
  
  

  You can verify the integrity of the binary by using this command in a Terminal window:

  spctl -a -vv malioc
  > malioc: rejected (the code is valid, but does not seem to be an app) 
  > origin=Developer ID Application: ARM Ltd (S345482SL3)
      

  Gatekeeper checks can be disabled by manually removing the com.apple.quarantine flag from the installed Mali Offline Compiler binary. Open a Terminal window, and run the following commands to disable gatekeeper:

  cd /Applications/Arm_Mobile_Studio_2020.0/mali_offline_compiler/ 
  sudo xattr -d com.apple.quarantine malioc
