Ok Moridin, thanks for that info. Question: you listed mA. What units are they in?

mA/second? per minute? per hour? I'll guess per hour...

25% increase for OMAP eh? So the current OMAP proc in our beloved tablets can be expected to push no more than 500MHz? Still not bad I guess....

Assembly? Really?

Can I see the source code? I'd love to learn ARM asm, but it's hard to find a good tutorial nowdays

Can you give us an URL to the code please?

I can't find the page at the moment. The only referenced thing is this, but it's written in C# and is too WM specific, I think.

That's the source code for the graphical frontend (and I think it does CPU scaling a la cpufreq). What one really needs is the source to the omapclock.exe application (http://www.meer.net/~dougt/random/OmapClock_0.2/). Someone might try decompiling it, but otherwise you're best off looking at the kernel code to see how the CPU speed is set currently.

Even better is wait until the n810's kernel code is released and look for the differences.

Reverse Engineering....? Please don't make me....

Well I compiled :

cpufreqd-2.2.1
sysfsutils-2.1.0
cpufrequtils-002

But I think you need to have a kernel module to go with it

Nokia-N800-26:~# cpufreq-info
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006

-g/--governor must be passed

Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?

Is it just a matter of building the right kernel module?

http://penguinbait.com/CPUFREQ.tar if you can do anything with it

cd /
tar cvf /path/to/CPUFREQ.tar

I have no idea what I am doing, so flame on!!

For information... On OS2008 running on N800 ps command show the following processes:

[dvfs/0]
/usr/bin/hal/hald-addon-cpufreq

These do not exist on OS2007...

is 2008 available somewhere, have I been in a coma?

Well... yes, but you have to work for some specific company...

Quick! Grab a copy of the process' binary and post it here!

"Flame on" lol. Now that's a phrase I haven't seen in a while. Nice


hmmm... googling "hald-addon-cpufreq"....
