ODROID-C1: 'Ondemand' governor holds maximum frequency

Postby sgrin » Tue Feb 03, 2015 5:40 pm

Hi,
i'm a newbee and i'm confused :?

If governor is set to 'ondemand' frequency is always 1536000 which is maximum allowed.
If governor is set to 'powersave' frequecy drops to 96000.
Then back to 'ondemand' and frequency immediatly rises to maximum again.
If maximum allowed frequency is set to 1632000 with 'ondemand' governor current frequency rises to that maximum.

I think I don't understand something...

Is that normal? How to get ondemand?

Thanks for reply.

I've tried conservative governor - it works better, most of the time frequency is 192000.

interactive governor managed to get 96000 frequency.

hotplug turned off 3 cpus and changes frequency from 96000 to maximum. When loaded with processes gets cpus on again.

I noticed this the other day also. It is strange, because when I was testing on an earlier kernel I was surprised to find ondemand worked. It seems it has gotten broken at some point, though :(
