Re: Overclock the N900?
You could try this:
cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state
It tells how much time the cpu has spent at different clock speeds.

Re: Overclock the N900?
I think it is:

sleep_while_idle 1
sr_vdd1_autocomp 0
sr_vdd2_autocomp 0

Re: Overclock the N900?
I forgot this once, you probably didn't :) But did you by any chance had it connected with usb cable to the pc as mass storage device at the time? (if so n900 umounts the cards)
Edit: Sorry, was a...

Re: Overclock the N900?
Could it be that the N900 running with an OC kernel became self-aware.. In this state it realizes its owner is trying to hurt it (or maybe just dislikes the company) and shuts down to the oblivious...

Re: Overclock the N900?
I just had to make one call to my oc'ed n900. Didn't even answer it(so rude)
Result:
> cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
600000
But according to Conky it's now reaching...

Re: Overclock the N900?
My latest try, if anyone cares :)
CPU 125/250/500/750/875 (very symmetric)
DSP 90/180/360/450/470
I noticed that the second fastest mode(750 MHz) now for the first time is being used a little...

Re: Overclock the N900?
Thats a valid point. I agree.
*** To permanent change max cpu freq ***
Update the file /etc/pmconfig
scaling_max_freq 600000
to
scaling_max_freq 900000
or whatever mhz you prefer or dare to...

Re: Overclock the N900?
I compiled a kernel with this settings
MPU 125/250/500/652/825 MHz
DSP 90/180/360/470/500 MHz
And i noticed (maybe a placebo effect) less freezing while recording video compared to the stock...

Re: Overclock the N900?
I have a question regarding cpu vs dsp speed. Looking at the stock version of the omap3-opp.h header file in the kernel source there seems to be a factor between the dsp and cpu frequency thats...

Re: Overclock the N900?
Just tested that on my N900 with the 125-900 oc kernel.
Got the result:
Nokia-N900-51-1:/# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
900000 550000 500000 250000 125000...

Re: Overclock the N900?
13046.8ms @ 900 MHz (using firefox from ovi)
-- edit --
hmm, I run the exact same test again and got
12843.4ms @ 900 MHz
That's better, but I don't believe it's right. I didn't restart the...

Re: Overclock the N900?
Thank you Lehto and all other contributors here.
I've been using the 125-900Mhz kernel for some hours now. No problems yet and it's definitely faster now.
- I've tried calling from it and to...
