Hello,

When I set the cpu frequency to “userspace” on one particular core (say core number 2), it is changed to all the cores. Similarly when I set the frequency to one core, it seems to be effected to all the cores. It is like they are working like a cluster. Is there a setting which I can use to disable it?

I am on TX1.

Thanks a lot

Hi solidrepellent,  
We confirm your observation. You cannot scale frequency on one single core. The change will get applied to all cores.

You can check the loading of each core via tegrastats.

Thanks for confirming this.
