VAnalyser : GPU utilization always at 100%

Hello community,

 

I am profiling an graphical application and I would like to know what is going on at the GPU level.

I am using a IMX6 Dual and it shows a 100% GPU utilization in the Vanalyser profiler. The GPU driver utilisation varies but I don't understand why the GPU usage figure is always 100%.

Is there an error in the VAnalyser/Profiler for this data ? (VAnalyzer v150)

If this is true, what does it mean ?

 

When I profile a vivante example (Tiger / coverfloaw ...) the value remains at 100%.

I am using a linux Yocto 3.10.17.

 

Regards

 

Sylvain
