I need to sample the vivante GPU load and frequency in i.MX 6 SoloX but the kernel doesn't give me access to any of the GPU variables. I tried activating the vProfiler as noted in the i.MX 6 Graphics User’s Guide but I cannot find ANYWHERE "Vivante Driver Development Guide" nor “How to Build the GCCORE Drivers for Android Platform.”
Moreover, there is no "install-recovery.sh" in which I can add the needed :
insmod /system/lib/modules/galcore.ko gpuProfiler=1 [OPTIONS]
chmod 777 /dev/graphics/*
Finally, is there a way to read the GPU frequency and load ? Very urgent please.
