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:
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.
I have solve this problem and now i can profil the gpu but i have another problem with vAnalyzer. If i try to add the output file it shows me this error as below:
i will appreciate your help
I ran into same issue; seems I was not passing the flag correctly as boot command argument and it got interpreted as string instead by my kernel (4.1.15 with a newer Uboot 2018.03). After using galcore.gpuProfiler=0x1 it worked correctly for me.
