How to get GPU(mali 400) utilization when system running?

Hank Lin

Hello all,

My device is samsung S3, and it's GPU is mali 400.

I want to know the GPU utilization and control GPU frequency when system is running.

But in /sys/module/mali/parameters, I can't find any file can do this.

Are there any suggestions??

Thank you very much

    I want to know the GPU utilization and control GPU frequency when system is running.

    The standard S3 kernel does this already - it is a standard means to manage GPU power use on portable devices - so I'm not sure what you gain my trying to do it again in user-space.

    HTH,
