How to calculate real time consumption for the I.MX6Q OpenCL kernels running on GPU

[haitaodeng]

Hello everybody:

Our board is based on SabreLite(i.mx6q), using Linux3.10.

We use the GPU(gc2000) inside i.MX6Q with OpenCL to do some image processing.

Are there any methods to test the real processing time, when running the I.MX6Q OpenCL kernels.

So that we can know that how long does it take a OpenCL-kernel to run on GPU.

By the way, could you tell us where can we find the latest GPU driver for SabreLite(i.mx6q) and how to configure the GPU driver.

Thanks for your time.

HI Haitao

I believe this could be estimated with profiling tools like

IMX6 Memory Bandwidth usage - RidgeRun Developer Connection

also for latest 3.14.38 drivers one can look at

Best regards
