Compiler/TDA2PXEVM: To get time information of openGL functions running in GPU

Hi,

To get the time information of functions running in Linux (a15 core), we have used OSA_getCurGlobalTimeInMsec(). But it doesn't provide information of openGL functions running in GPU ( gives 0 msec).

Is there any function to get time information of openGL functions running in GPU?

Hello,

Could you tell us what you are intending to do? Are you trying to measure a frame time? To profile GPU, you can use PVRTune:

https://www.imgtec.com/developers/powervr-sdk-tools/installers/

Please note that you need "PVRTune for SGX"

If you want to do calculation on host side, you could keep a track of number of frames submitted over a period of time and average that. Since GPU runs asynchronous to driver, measuring time of OpenGL functions will generally not give an idea of the GPU loading.

Regards

Hemant
