Is it possible to scale the frequencies on MALI T628 GPU?

Dear All,

Could I ask it is possible to scale the frequencies base on MALI T628 GPU?

I just want to see the performance differences when I varied the frequencies.

And the other question is I saw an OpenCL guide instruction for Samsung Chromebook,

but also can I use that user space driver and settings for my HP chromebook 11?

I tried many times to compile and run several sample applications which are included in MALI OpenCL SDK, but failed.

So if frequency scaling is supported and HP chromebook 11 does not support for OpenCL programming,

then I am thinking to buy new samsung chromebook 2.

Thanks a lot in advance,

Woojung Myung
