Besides benchmarking, currently we are doing deeper investigation for GPU performance when running our application.
Basically we want to know how our application utilize GPU when drawing into screen.
We use Vivante Tool Kit that is available on Freescale website.
We are able to get GPU profile data by using vProfiler, and use vAnalyzer to analyze it.
It is a per frame data that consist GPU cycles count, time, etc.
But we found some data are strange about GPU utilization result.
It seems that GPU idle cycles is always 0, which will impact to GPU utilization to become always 100% for every frame.
The same result is also acquired when we tried using another application with a simple interfaces that only shows buttons, texts and spinner.
GPU utilization is always 100%.
We found very little information on the internet about Vivante Tool Kit usage, so we can not decide if the data is valid or not.
Do you have any information about Vivante Tool Kit ? or have you ever been using this tool ?
Specially about "GPU Utilization is always 100%" matter, we want to know if the data is valid or not.
It will be very helpful if you can support us regarding this matter.
