CoreTile V2P_CA15_A7 OS DVFS support

Zacharias Hadjilambrou over 11 years ago

Hi,

I want to ask if the CoreTile V2P_CA15_A7 board (the big.Little) supports operating system level DVFS. For example is it possible to scale the cores frequency and voltage on this board using a linux command like cpufreq?

thanks - Zacharias

Hi Zacharias,
I found this app note which explains how to do it: AN318 - CoreTile Express A15x2 A7x3 Power Management
There's a subsection for the DVFS interface which should help.
Thanks,
Joe

Hi,
Thanks for the response. I saw the app note. It seems that the interface for the OS DVFS control exists. I was just wondering if anyone knows any Linux program that implements this interface and if anyone actually tried it.
thanks - Zacharias
