powertop for N810
 

I compile powertop on N810
http://www.lesswatts.org/projects/powertop/
But N810 kernel compiled without CONFIG_TIMER_STATS.
Do anybody have kernel with CONFIG_TIMER_STATS?
Where can I get N810 kernel patches?

Re: powertop for N810
 

svs, nice work. Mind sharing your binaries here?

You can recompile a new kernel in scratchbox.

Run apt-get source kernel-source-rx-34

Actually, I plan on modding and releasing uberkernel. Be a long time before I get round to that though.

What repostory have kernel-source-rx-34?
Thanks

mv powertop.deb powertop.gz
gzip -d powertop.gz
chmod +x powertop
mv powertop /usr/local/bin

http://repository.maemo.org/pool/chi...-source-rx-34/

From there. Sbox should get it by default as that repo is standard. But you can download it yourself and apply the diff that is in that folder with zcat.

I can't download 55,8MB kernel source now.

Re: powertop for N810
 

I compiled it once a while ago, but I it wouldn't load the modules that went with the default Nokia kernel. You'll probably need to recompile those as well, I guess...

Re: powertop for N810
 

Nokia kernel was compiled with unset CONFIG_TIMER_STATS.
Without CONFIG_TIMER_STATS powertop is unusable.
I'll try to recompile kernel later.

Re: powertop for N810
 

Can someone please compile this in one of the kernels like the one with rotation support?

Re: powertop for N810
 

Believe me, it's not worth it.

I've tried so much times to compile a kernel with CONFIG_TIMER_STATS. I could only get it to boot up with a stock kernel with just that enabled and then when the wifi was enabled, the tablet would lock up.

Re: powertop for N810
 

Hmmm OK well, that is strange because I know a nokia kernel developer is using PowerTOP. I'll ask him if he can give me his kernel, but I don't know what dependancies it has and such...

I'm finally setting up a Scratchbox btw...

Message from power top:
...
No detailed statistics available; please enable the CONFIG_TIMER_STATS kernel op

I compiled kernel with CONFIG_TIMER_STATS
But got problem with wi-fi driver.
I dont't know where is correct wi-fi sources

Re: powertop for N810
 

they're in scratchbox:
apt-cache search cx3110x

Re: powertop for N810
 

Is there any advancement in this project?

There is now also LatencyTOP.

LessWatts might not be very useful, but it reminded be about relatime which isn't supported yet in the Linux kernel used by the tablet. So I disabled atime for my SD card (forgot to do disable this...)
