I wanted to calculate the GPU usage. Is there any file for GPU similar the way cpu stats are saved at /proc/stat ?
What could be the approach to get the GPU details like frequency etc
Thanks

Since Android 4.3 (Jelly Bean) you can monitor this from a tool in Dev Options. Seetings > More > Developer Options > Profile GPU Rendering. You may need to enable Developer Options on Android 4.2 as it is hidden by default. Enable this by tapping 7 times on Settings > About phone > Build number.
To monitor the overall GPU resource usage, click the Performance tab, scroll down the left pane, and find the “GPU” option. Here you can watch real-time usage. It displays different graphs for what is happening with your system — like encoding videos or gameplay.
Does Android Studio Use Gpu Or Cpu? As you know, Android Studio uses an internal graphics card by default. In the case that your system has a dedicated graphic card, you can enable Android Studio so it is able to use the GPU in the graphic card settings.
Every smartphone has a GPU in some form to generate pictures. It's an essential part of phone's structure. Without GPU in smartphones, the possibility of having high-performance games or having high-quality UI would be impossible. The architecture of a GPU is almost similar to a CPU.
AGI (Android GPU Inspector) by Google, is currently in Open Beta, and only supports the following devices:
DEVICE NAME GPU NAME
Google Pixel 4 (standard and XL) Qualcomm® Adreno™ 640
Google Pixel 5 Qualcomm® Adreno™ 620
Google Pixel 4a 5G Qualcomm® Adreno™ 620
These devices do not support AGI yet but will offer support in the future:
DEVICE NAME GPU NAME
Google Pixel 4a Qualcomm® Adreno™ 618
Samsung Galaxy S10 series Qualcomm® Adreno™ 640 and Arm® Mali™ G76
Samsung Galaxy S20 series Qualcomm® Adreno™ 650 and Arm® Mali™ G77
Samsung Galaxy Note 10 series Qualcomm® Adreno™ 640 and Arm® Mali™ G76
Samsung Galaxy Note 20 series Qualcomm® Adreno™ 650 and Arm® Mali™ G77
This will allow you to profile your app's GPU usage.

For Arm Mali GPUs, you can use Streamline, a performance profiler that is part of Arm Mobile Studio: https://developer.arm.com/tools-and-software/graphics-and-gaming/arm-mobile-studio/components/streamline-performance-analyzer
Mobile Studio is free, and there are some good video tutorials for it.

Profile GPU Rendering has a few options, 'show on screen as bars' is quite a good way to get a fast visual look at what's going on.
