Hello,

i have already read this article. but i need more information about GPU Profiling using Vivante Tools. I'm using i.MX6Solo to make UI with Qt Framework. I need to profile the GPU to know how works it with my UI.

I have setup the u-boot and system envs as below:

U-Boot:

galcore.gpuProfiler=1

galcore.showArgs=1

User-space:

USE_PROFILER=1

VIV_PROFILE=3

VP_FRAME_END=1024

VP_FRAME_NUM=1023

VP_FRAME_START=0

VP_OUTPUT=foo.vpd

VP_SYNC_MODE=0

 

cat /sys/module/galcore/parameters/gpuProfiler is always 0 but i use echo 1 > /sys/module/galcore/parameters/gpuProfiler

 

after UI starts the tool makes foo.vpd but it is 0 Bytes. Nothing is inside.

 

Do i miss something?

 

thank you for reply.

 

Zanam
