Re: kernel-power patches/updates
 

Seems that nobody is maintaining it. It would be great to have an updated version with the bleeding edge wifi drivers included.

Re: kernel-power patches/updates
 

If you want a bleeding-edge power kernel, take a look at kernel-bfs. It's power46+BFS+wl1.

Although, I had to tweak my Swappolube settings, enable HWSync and mlock hildon-desktop to make it feel as smooth as CFS.

Re: kernel-power patches/updates
 

I assume you are refering to v0.46?

I'm sure that it is receiving some attention because it's functionality is an integral part of the h-e-n software, which is being worked on. There are patches on the garage site but, I agree, it's not clear whether or when they're going to get integrated into the kernel itself.

There is a possibility that certain sections will be merged into the CSSU [Someone please confrm/reject this].

Other factors that would reduce development on this, apart from the developers having lives/jobs/families/etc, is that the CSSU is something of a priorty task (AFAICS), then there's Meego and the Meego coding competition, etc, etc...

- all the same, thanks for flagging this up, it's good to find out what's going on from time to time. From my point of view, it would be good to have a development status paragraph in the maemo wiki so it's clear what's being worked on (and what's not). Also, this might allow others to contribute if they knew what could be done to assist.

Edit: Thanks Hurrian. Have you tried this? Please comment on stability/battery drain/anything else you've noticed...

Re: kernel-power patches/updates
 

If nobody maintain power kernel I can create new build with these patches (and post here):

+ enable more usbnet modules (usb <--> rj45 chip modules for host mode)

Re: kernel-power patches/updates
 

Could you backport some drivers from meego kernel? like de powervr driver with vsync? Sorry if is a stupid question

Re: kernel-power patches/updates
 

See this: http://talk.maemo.org/showthread.php?t=70082
Maybe if I have time I will took at.

Re: kernel-power patches/updates
 

@demolition : I had to use the IO Improvement Swappolube tweaks to make it stop locking up and rebooting whenever I use Easy Debian and do a full upgrade.

BTW, is there any way to get the device into noop? Every time I try to change the scheduler, I get permission denied. (even with sudo!)

Re: kernel-power patches/updates
 

So, Titan does not responce to my mails....

As I wrote http://talk.maemo.org/showpost.php?p=983930&postcount=5 Now I builded new kernel packages based on power-kernel v46 (without patched wifi driver yet) but due to size limit I cannot uploaded deb packages here.

Does anybody know good upload server?

Re: kernel-power patches/updates
 

Why not use mediafire or rapidshare?

Re: kernel-power patches/updates
 

Maybe you could ask a "space" in the CSSU git repositories so you would have lots of space and it would be easier for others to contribute as well?

Thanks for looking into this BTW!

Re: kernel-power patches/updates
 

Echo noop to /sys/block/mmcblk0/queue/scheduler as root (sudo won't do)

Re: kernel-power patches/updates
 

I am interested on DVB-T and DVB-S usb modules, so it is nice if someone can compile these modules too.

i.e: http://www.geniatech.com/down-eng/dv...inuxdriver.zip

But mainly I need a power kernel with framebuffer active (to see logs on boot) and unfortunately until now I haven't had time to do it by myself

Re: kernel-power patches/updates
 

I compiled power-kernel with external framebuffer modules (so you can load it to see log). I publish my builds later.

If usb modules which you need is in upstream kernel tree I can build it.

Re: kernel-power patches/updates
 

@pali
Please compile it also with lxp's injection feature please... I'm currently using it to get in my cousin's router which is beside our house :p Since mobile internet is expensive here haha

I'm using it almost 2 times a month so I really need it :D

Re: kernel-power patches/updates
 

And oh and a simple question... Is it possible to add exfat support for maemo?

Re: kernel-power patches/updates
 

You could always ask MohammadAG if you could use his server to upload your files?

Also could you possibly update the kernel to the MeeGo kernel?

It would be nice to have the latest kernel with the latest drivers installed. Should remove the VSync issue and possibly give us much smoother transitions within games and the UI in general :)

Re: kernel-power patches/updates
 

I can ask If I do not have place for publishing files in next days.

See: http://talk.maemo.org/showpost.php?p=983936&postcount=7

Same as for usb modules: http://talk.maemo.org/showpost.php?p...4&postcount=14

Re: kernel-power patches/updates
 

dont know if i am late to the discussion, bt maybe i can help with providing server space.
how much do you need to upload?
any specific requirements server-side or merely space?

Re: kernel-power patches/updates
 

Cool! So please do include it please :D
I'd like to compare MyDocs exFat and SDX card for this. And please upload it to a temporary file sharing site ATM can't wait to test it :rolleyes:

Re: kernel-power patches/updates
 

I think that there are no working exFat linux drivers and sure that thare is nothing in 2.6.28 tree!

Re: kernel-power patches/updates
 

Ok I didn't know that :p Well too bad but stil can't wait for the newest compiled kernel at least with lxp's and BFS patch 0.o

Re: kernel-power patches/updates
 

As I wrote I did not compile it with lxp's patch yet, see: http://talk.maemo.org/showpost.php?p=989794&postcount=9

Re: kernel-power patches/updates
 

Call me stupid if you wish, but can someone help me on how to make modifications to kernel-power source . I mean - every time dpkg-buildpackage is run patches from debian/patches are de-applied and re-applied making it impossible for me to modify actual code without some ugly hackery.

What is correct sequence/procedure? Any hints?

BTW what I am trying to modify is dspbridge driver, code from omapzoom git looks pretty similar to what we have in kernel. Maybe if I succeed I will be able to run 720p codecs from android.

Re: kernel-power patches/updates
 

excellent freemangordon.. someone please clarify.. It will be great if we can use the libraries from meego which should solve the vsync issue as well.
(repeatt to self.. patience is a virtue ;-))

Re: kernel-power patches/updates
 

Apply quit patches from debian/patches ( run command: QUILT_PATCHES=debian/patches quilt push -a -q ), then do backup (kernel-power.orig directory). Then modify kernel tree with your changes and generate patch between working tree and backup. Copy your diff to debian/patches and fix debian/patches/series

Re: kernel-power patches/updates
 

So, now I uploaded my kernel packages to server http://atrey.karlin.mff.cuni.cz/~pali/

Happy downloading :)

Re: kernel-power patches/updates
 

Some step by step instructions would be much appreciated :)

What to install and in what order ect. What each one does :)

Re: kernel-power patches/updates
 

whats updated in this kernel you posted?

Re: kernel-power patches/updates
 

Please note that this is not user-end packages so may be unstable!

Download kernel-power, kernel-power-modules and kernel-power-flasher. Then install these 3 packages with dpkg.

See: http://talk.maemo.org/showpost.php?p=983930&postcount=5
All except patched wl12xx module.

Re: kernel-power patches/updates
 

Hi Pali,

Regarding this comment from you:

What about package/plugin status-area-applet-battery ( http://maemo.org/packages/view/statu...pplet-battery/ )? Is there any chance to replace (or fix) this applet to read bq27x00 info when bme is stopped? With source code of this applet will be simple to write patch, but it is closed...

You can check with Smoku, as he's working on a replacement for the widget in the Cordia project:
http://gitorious.org/cordia/cordia-status-plugins

Re: kernel-power patches/updates
 

Framebuffer active ?

Re: kernel-power patches/updates
 

Yes this build include framebuffer modules. Load it with: modprobe fbcon

Re: kernel-power patches/updates
 

i cant install the packages.

erros message comes up with broken package.


is there a way to geht only the fbcon module into da normal kernel-power?

Greetz
Erazor


btw Thx for your work :)


//edit:
got it. there was a corrupted download ^^
but fbcon doesnt show me the commandlines on boot.

is there anything else i have to do?

modprobe already done ;)

Re: kernel-power patches/updates
 

Downloading now... :)
When can we expect lkp's patches pali?

Re: kernel-power patches/updates
 

Interesting effect of the patch. The battery temp reads 346. Am assuming my battery temp is not 346 Degrees :)

Re: kernel-power patches/updates
 

after modprobe fbcon framebuffer console is actived. This is not permanent, after reboot you need modprobe it again.

If you want to see kernel output when booting, you need to modify preinit script (or add modprobe command to /boot.sh)


I do not know now. It is not simple to integrate wireless-testing patches to power-kernel...


And who told you this value?? bq27x00_battery module export temperature value to file /sys/class/power_supply/bq27200-0/temp in tenths of degree Celsius (kernel modules must export value in this unit - it is defined in kernel doc!). So if you read 346 from this file, temperature of your battery is 34.6 °C

Re: kernel-power patches/updates
 

Hi Pali, your work is very much appreciated.

Have you considered to request being the maintainer for Kernel Power? You could promote v46 to Extras Testing (I thing it's pretty stable and almost everyone is using it) and upload a new v47 to Devel.

I'm actually using a custom Power Kernel with the Bleeding Edge Wifi drivers so having them included in upstream package will be very nice.

Re: kernel-power patches/updates
 

Ahh excellent. The old version of the module wrote to that file the value in whole Deg C not tenths. Thanks for the info.

Re: kernel-power patches/updates
 

If more people test my builds and there will be no problems I could ask devs. about updating kernel-power package in extras-devel.

So please test by builds if all works fine and which other (usbhost) modules you need to compile...

See this for more info about battery status:
directory /sys/class/power_supply/bq27200-0/
file /sys/class/power_supply/bq27200-0/uevent
output from command: lshal -u /org/freedesktop/Hal/devices/computer_power_supply_battery_bq27200_0

I think this is all what is possible to know about battery (from bq chip datasheet).

I wrote patch for opensource battery-widget which read battery state from bq driver: http://talk.maemo.org/showpost.php?p...&postcount=674

It show battery state when usb hostmode is active too :)
