vProfiler in android and GPU frequency and Load

oussamadjedidi — Fri, 24 Feb 2017 16:22:49 GMT

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 :

#!/system/bin/sh
#
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.

Hi,

The environment variable VIV_PROFILE can be used to enable or disable vProfiler. By default, vProfiler is disabled in the driver. The command below will enable vProfiler. Set VIV_PROFILE equal to 0 to disable vProfiler. export VIV_PROFILE=1

To enable vProfiler Option in Kernel only need to add a sentence "galcore.gpuProfiler=1" in the attribute of bootargs in your boot configuration. For example, we can configuration bootargs like: setenv bootargs 'console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=400M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=512M androidboot.serialno=1e09a1d4d72d78a9 galcore.gpuProfiler=1'.

In general suggestion and general procedure to enable vprofiler and vanalizer could be found in the VDK documentation.

Dear Bio

Do you mean we don't need to modify Android BSP code but only set galcore.gpuProfiler=1 can enable the vProfiler?

Just tried to set it in my boot command, but the command "$setprop VIV_PROFILE 1" still can generator nothing...

And seems there have no onProperty change can be found in the init*.rc for VIV_PROFILE, VP_OUTPUT, ...etc
