omap cpu clock
 
On omap processor specs http://focus.ti.com/lit/an/sprt495/sprt495.pdf I found that it can run deep to 125 MHz @ 0.95 V but with conky program i see cpu freq low only at 250 MHz.
Can be an improvement to battery life if cpu freq down to 125 MHz when stand by. This can be a software ( kernel ) limitation or is hardware related ?

stand by? Do you mean locked and screen off?

Re: omap cpu clock
 
standby = no pulseaudio, no network traffic, no background programs no nothing.
even a static image on screen mean standby.

Re: omap cpu clock
 
In standby the CPU switches completely off. In that state CPU frequency doesn't matter.

Should be moved to brainstorm. I would vote for this. :)

Edit:
I don't think the cpu shuts off completely in standby.

Yes. This is what it thought when I asked my previous question. Anyone can test this by running powertop while in standby.

Useless. As you can verify with powertop, the CPU spends most of the time (when the device is in "standby") in C4 state where the clock is not running.

I vote for
Even if proc can reach halt state, I want also 125 MHz freq.
'standby' is not a happy word let say instead 'waiting input'

I think desktop proc state C4 don't fit on omap architecture

C4 on OMAP is not so deep as C6-C7 when they agree on base 0 or 1

Look closer on page 6 in my first post - 22 mW on audio decode !
and "More specifically, the OMAP3530 processor divides
its functional blocks into 18 power domains, each with its own switch. The PRCM can switch all the power
domains, but many of them can also be user-controlled."

and some definitions
C1 . MPU WFI + Core active
C2 . MPU WFI + Core inactive
C3 . MPU CSWR + Core inactive
C4 . MPU OFF + Core inactive
C5 . MPU CSWR + Core CSWR
C6 . MPU OFF + Core CSWR
C7 . MPU OFF + Core OFF

Powertop statistics don't fit omap power granularity

Re: omap cpu clock
 
At some point it becomes more power efficient to complete the work faster, so the CPU can go back to sleep faster..

Re: omap cpu clock
 
/sbin/powertop would need to have unlimited sampling time, which could be interrupted with CTRL C.
Now if CTRL C is pressed during the data collecting, it just quits.

The idea would be to let it run and collect statistics after battery is fully charged, until the device's battery is almost empty. Then interrupt and see how much time the device spent in different stages.

Something on your desktop is doing alot of crap.. Display is off most of the time yet CPU is active all of the time..

Re: omap cpu clock
 
I want 125mhz it could be used for example when only listening to music? where the cpu is still needed but not that much.

I guess this was for me?

I'm still learning to read that output from powertop.

How do you see, the device has its display off most of the time?

I had idle ssh-connection and idle microBrowser connections and I think only Conky running in the backround.

Then I had that stepcounter widget turned on, so maybe that woke up CPU often during those 10 minutes.

Just for an exercise, I had N900 idling 6 hours and left powertop to monitor it during those 6 hours.

There is bugs in powertop, looking the output:

Charger doesn't cause 500Mhz but plugged into the PC via USB does.
