How to adjust Vivate GPU frequency on Android

[namyongpark]

Dear.

I would like to adjust GPU frequency, governor on sabresd board.

But I can't find the path that located gpu information.

Usually the path is located at sys/device/platform/ or sys/class/....

I totally explore shells, but I can't find any gpu information.

CPU can easily find on sys/devices/system/cpu so I can hotplug it.

Is there any one who knows the shell path of gpu for adjusting gpu frequency and governors?

Thanks.

Hi,

Yes, for the cpu you can find sys/devices/system/cpu .And use the follows commands, echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor. To check other possible modes:cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors.

About the GPU, you can refer to https://community.nxp.com/thread/320827#comment-390504

Hope this can do help for you
Have a great day,
Rita
