Re: Update for Enhanced kernel for power users just released
 

Here's a good summary of the kernel versions based on a test basis.
Kernel-Power with Matan's uboot[v41 to 43] - Works only on n900 with hardware version 2101 or lower than 2204

Kernel-Power with unmodded uboot[v44 to 45] - Works if there is a external mmc on your n900(without microsdhc inserted it get's stuck at uboot cli)

Kernel-Power(plain)[v46] - Works perfectly



Note: I'm not sure about the version numbers I don't remember clearly.

Re: Update for Enhanced kernel for power users just released
 

I have used v45 without mmc just fine... now on v46 and loving it :)

Re: Update for Enhanced kernel for power users just released
 

Me too. Had no problem with v45 and even didn't try to boot meego from microsd.

Re: Update for Enhanced kernel for power users just released
 

I updated to kernel46 and after that i installed multiboot, now i can only choose omap1. How can i edit multiboot that it shows me v46 as a second choise , please help me :)



Edit it just tells me "required files not found -> panic" :eek:


Edit 2 nevermind got it ;)

Re: Update for Enhanced kernel for power users just released
 

Ohh so I guess it's different cases on each phone :- /
Thanks for verifying btw!

Re: Update for Enhanced kernel for power users just released
 

Is it coincidence? I notice MUCH better cpu handling now with v.46. Before I would wake in the morning and look at Battery Graph to find that, with no apps running through the night and wifi killed, the cpu would be doing regular little climbs up to about 30 or 40%. Now, it still shows cpu activity, but the percentages are so small as to be almost unnoticeable on Battery Graph.

Re: Update for Enhanced kernel for power users just released
 

hmmmmm.. okay. when I tried it my battery drained much quicker than v45.. (still running v45 atm)

Re: Update for Enhanced kernel for power users just released
 

can someone with v42 and non working camera test this please:

Re: Update for Enhanced kernel for power users just released
 

hey! My camera is not work with this kernel power! i have tested your fcam-driver_1.0-2 is not installed!

Sorry for my poor english.

Re: Update for Enhanced kernel for power users just released
 

found this code using the search bar

then reboot.....test your camera (and audio too).

Edit: my problem was my audio and camera, but this post here only fixed audio (as i understood) but fixed my camera as well.

Re: Update for Enhanced kernel for power users just released
 

Since kernel-power v46, uboot support has been dropped for some reason.
I decided to upload a package that includes uboot support.
Package name: uboot-power
Based on kernel-power v46.
It boots both maemo and MeeGo without any issues.
Usual warnings apply

P.S, unlike the source of uboot-pr13, this one does not contain binaries, I hope uboot-pr13 will be updated to remove the binaries in it.

Re: Update for Enhanced kernel for power users just released
 

awesome! thank you so much! saved me alot of time switching between meego and maemo!

this is what i did:

wget http://repository.maemo.org/extras-d....2-1_armel.deb

dpkg -i uboot-power_0.2-1_armel.deb

all done in kernelpower46! works flawlessly! booting to meego now!

Re: Update for Enhanced kernel for power users just released
 

ok, now i want to return to maemo .

I know I have to press any key while in uboot and type " run noloboot"

but my phone keeps shutting down.

I have multiboot installed, how can I boot to multiboot from uboot?

am stuck now. oops

Re: Update for Enhanced kernel for power users just released
 

uboot in kernel-power 45 caused problems with some hardware revisions of N900s, other than revision 2010 I think it was.

AFAIK the power45 and power46 kernels are the same except for 2 things: power 46 dropped uboot support but added BT mouse support.

Re: Update for Enhanced kernel for power users just released
 

Not sure about problems (I'm sure you meant 2101 btw), I'm not using the u-boot provided by titan/Matan, this is straight from the u-boot git page with the N900 patches applied.

Re: Update for Enhanced kernel for power users just released
 

Hmm. Which means I need to still make my own uboot+power46 image when I figure out how to either get or compile a mkimage binary for my N900 (or crack and do it from a Debian VM, but I like the aesthetic of making the kernel image onboard the N900).

Nevertheless, thank you for providing this. It makes me happy to have the uboot screen back, even if I'm not dual booting regularly - just so that I can have it when I build up the motivation to learn how to partition drives/(other-name-for-all-computer-storage-media) correctly.

Re: Update for Enhanced kernel for power users just released
 

Would it be possible to include hid-apple module to next versions of "Enhanced kernel". Let me know if there is some other channel for this enhancement request.

Looks like there are some Apple Bluetooth Keyboards that work without it, but other don't.

http://talk.maemo.org/showthread.php?t=41845

I can confirm that mine will connect but don't work. However, after compiling hid-apple.ko for power-kernel v46 and using that, my keyboard finally works with n900.

Have the same issue. Installed v46, OC - worked just fine. Installed NITDroid, played with different options - at one point had 5 multiboot options (3 working). Upgraded NITDroid to 0.0.9 and from there - cannot start V46 any more. Only option (other then NITDroid) is OMAP1 - stock kernel. No OC any more inspite V46 is installed. Any suggestions??? Would VERY MUCH apprecaite any advise... TY!

[QUOTE=3SCoach;909579]I'm no expert, but check that the required vmlinuz-??? files exist in the /boot/multiboot directory & that matching .item files exist in the /etc/multiboot.d directory.

Re: Update for Enhanced kernel for power users just released
 

Anyone tried compiling compcache/zram 0.7 for kernel-power 46? I'm trying to do it in easy-debian using the unpacked kernel-power-*-source package... but it's complaining that Modules.sysver is missing. Been a while since I was compiling kernels...

Re: Update for Enhanced kernel for power users just released
 

I just performed this update. I also tried the library cp command listed elsewhere this thread. Starting the camera just leads to "operation failed"

Re: Update for Enhanced kernel for power users just released
 

For some reason that didn't work for me like it has in the past unfortunately.

In the end I still did all of the above but renamed and moved /boot/zImage-2.6.28-maemo46 to /boot/multiboot/vmlinuz-2.6.28.10power46

I renamed /etc/power.conf.example to /etc/power.conf

Then I added a file in /etc/multiboot.d called 33-Maemo-power46.item with content:

ITEM_NAME="Overclock Maemo"
ITEM_KERNEL=2.6.28.10power46
ITEM_MODULES=ext3

All working again.

Re: Update for Enhanced kernel for power users just released
 

Yes, the Fcam drivers do say "Incompatible Package"

Re: Update for Enhanced kernel for power users just released
 

@dchky

I installed NITDroid today and had the same problem with overclocking.
Your solution worked perfect for me.

Thanks.

Re: Update for Enhanced kernel for power users just released
 

My N900 also failed the Camera test. :-(

Does anybody know how to get the camera working with kernel power?

Re: Update for Enhanced kernel for power users just released
 

I have also this probleme! please help me!

It's posible to install a old kernel power?

Sorry for my bad english, Thanks.

Re: Update for Enhanced kernel for power users just released
 

i beleive you need to reinstall the fcam drivers from terminal. search forums for 'operation failed'

Re: Update for Enhanced kernel for power users just released
 

it was posted a few pages back

easiest is to just update everything

sudo gainroot
apt-get update
apt-get upgrade

reboot should be good to go.

Re: Update for Enhanced kernel for power users just released
 

Any of you guys have problems with playing videos on media player? (with v46, I am having problems atm, if I use stock kernel it is ok, if I use default settings of enchanced kernel it is ok, but if overclock it my videos won't play.)

Re: Update for Enhanced kernel for power users just released
 

The last time i tried a 'power kernel', my idle power consumption went from 2mA to 15mA, which means constant battery drain while not using the device.

https://wiki.mozilla.org/Mobile/Powersaving

To measure your idle power drain, shut off all user programs, go to offline mode and run the "./bq27220.sh 30" command, then let the backlight go off. Your target should be 2-3 milliamps.

Re: Update for Enhanced kernel for power users just released
 

I could be wrong, but i seem to remember discussion of similar troubles when the DSP was set too high and/or the voltage too low. remember overclocking IS NOT 'stable' and as we have seen already different n900s have different tolerances for it.

Re: Update for Enhanced kernel for power users just released
 

not pushing too far, just 900 mhz? It was stable enough except running 6-7 web windows at the same time and changing windows like I am on PC. Seems I can't accept N900 is a little bit "slower" compared to my PC :)

changing voltage adjustments had no possitive effect (about playing video).

Re: Update for Enhanced kernel for power users just released
 

what you using for overclocking? xlv ulv ideal??? i use to have that problem thats why i tried everything mine is stable at xlv but cant play videos on ulv figure that out lol...

Re: Update for Enhanced kernel for power users just released
 

How to run that, I'm already root and it says permission denied. What permisson does it need more?

Re: Update for Enhanced kernel for power users just released
 

There is no safe overclocking number such as 900 mHz. If you read the overclocking docs on the Wiki (and you should), you will find a table estimating what percentage of N900s fail at what setting.

Re: Update for Enhanced kernel for power users just released
 

I did, mine didn't fail btw :)

using stock kernel atm.

Re: Update for Enhanced kernel for power users just released
 

I have been having problems with the Camera for a while. I had been using the 2.6.28.10-power42 kernel for a while, using the ideal settings. I had just been lazy to try to get it resolved. I figured it had to do with the FCamera drivers, or with LiveFocus, or something like that. I was also experiencing crashes with SomePlayer when playing high bitrate ogg files (320 kbit/s).

Today, I finally decided to resolve the camera issue. I updated the kernel to 2.6.28.10-power47. I also updated FCam to the latest version (in devel). FCam worked fine, but the camera app continued to crash (and make funny noises when recording video). I read (somewhere) a post recommending against overclocking. So, I tried using the following command:

kernel-config load lv

And sure enough, the camera worked fine after that. So, I figured I would just use the lv settings when using the camera and the ideal settings for everything else. I then decided to test whether the updated kernel had any effect on my SomePlayer crashes. I quickly was able to crash it playing a high bitrate ogg file. For kicks I decided to try it using the lv settings. To my delight SomePlayer was able to handle the high bitrate file and has been rock solid ever since.

So, I figured I would post this here to see if it helps any one else.
