How to check whether i.MX6Q GPU acceleration is valid.

[satoshishimoda]

Hi community,

I have a question about i.MX6Q GPU.

I consider using Qt GUI with Linux system.

Then, I want to check whether CPU acceleration is valid or not for drawing Qt GUI.

Could you let me know how to check it?

Actually, I came up with two methods as below, but I cannot judge to "GPU acceleration is valid" with both methods.

----------

1. Check whether OpenGL ES libraries (e.g. ligGAL.so, libEGL.so, libVIVANTE.so, etc...) are loaded when Qt process is running.

I can understand what libraries is loaded, but cannot conclude to "GPU acceleration is valid".

2. Check CPU load by top command when GPU sample program (gpu_sdk_v1.00.tar.gz) is running.

I can guess "maybe, GPU acceleration is valid because CPU load is low", but cannot conclude.

----------

Yes, it should be accelerated by GPU, in order to see how much (in numbers) is accelerated, you can check it with the vProfiler tool,

If you already have the GPU_SDK, please check the Documentation folder, in order to use the profiler, if not You can download the vivante tools from:
