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
Dear timhar01
Really thanks for your detailed explanation about those questions
Probably I need to change my target system to Chromebook 2.
Btw, you mentioned "you have 6 cores arranged into 2 core groups, 4 + 2. These appear as separate platforms within the GPU device."
this sentence means if I want I can use 2 max compute units or 4 max compute units whether which GPU platform I choose, right?
Thanks a lot, Tim
Hi Woojung Myung,

Yes, that's right. It's not as fine gained an approach as device fission, but it gives you some options.
I have checked about the HP Chromebook 11. It should certainly be possible to use this like the Samsung Chromebook with only a few small changes to the instructions. However it's not something we have tested fully yet and I don't currently have a timescale for when we will publish a guide to include this device. Bear in mind that the HP Chromebook - like the Chromebook 1 - has 4 GPU cores in a single core group. For the 2-core group, 6-core GPU you would need either of the Chromebook 2 models.
