Adreno Profiler and disabling DCVS

Hi,

I'm trying to accurately measure the kernel execution time of my OpenCL app on the DragonBoard that contains a SnapDragon 800 SoC. The results I get indicate that I should disable DCVS on the SoC to get accurate results (I measured more GFLOPS than actually would be possible).

I read that DCVS disabling can be done in the Adreno Profiler. Unfortunately it seems that it is not possible to have my app work with the profiler. Is there any way to have DCVS disabled (and keep it that way) with the help of Adreno Profiler or without it? Anything that works would be of use for me. As I said, it's probable that I can't make my own app Profiler compatible, but I've managed to connect an OpenGL example app to the Profiler already. However, it seems to me that DCVS is re-enabled right after that OpenGL app finishes.

Thanks

Jani
