30customization with AAOS team.
31* For example, to generate the change report for Android 11 to 10 QPR3: [sysui_gcar_android10-qpr3-release_android11-release.txt](dev/resource/sysui_gcar_android10-qpr3-release_android11-release.txt)

34$ ./sysui_oem_diff.sh ~/Android/android11-release remotes/aosp/android10-qpr3-release remotes/aosp/android11-release > sysui_gcar_android10-qpr3-release_android11-release.txt
35```

37## System Performance Tuning
38AAOS system performance turning is hard. Here are the tools to make it a bit
39easier for the device developers.
