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.

----------
