Re: [Announce] kernel-power v48

I installed v48 and the power kernel settings. Can't find the settings application anywhere.
When I use the uname -a
the response I get is

Linux Nokia-N900-2.6.28-omap1 #1 PREEMPT Sun Aug 8 09:50:47 BST 2010 armv71 unknown

Is this the correct response or did something go wrong?

Re: [Announce] kernel-power v48

that is stock (Nokia) kernel, not kp48

Did you reboot?

Then you missed something on the way... Check the instructions and try it again.

Re: [Announce] kernel-power v48

I have multiboot installed, just noticed (booting with keyboard open) that another item (power kernel) appeared - my fault!

Selected it and now get

Linux Nokia-N900-2.6.28.10-power48 #1 PREEMPT Mon Aug 22 15:09:51 EEST 2011 armv71 unknown

That looks better but I still don't see the kernel settings (to o/c etc) - should that be on my hildon desktop?

Re: [Announce] kernel-power v48

You don't "see" them, at least if you don't have visions. The 'kernel-power-settings' consist of kernel voltage and frequency profiles (explained in simple form), and tools to load & set them. You'll have to use xterm for this.

Do not do it, maemo reports OOM with only 384 MB memory. Also see here http://talk.maemo.org/showpost.php?p...postcount=1229

EDIT: also are you sure you have correct swap priorities? Because adding swap with busybox's swapon leaves newly added swap on the tail, i.e. it will be use when flash swap is full.

omap1 is the stock value for sure .
means you are running the stock kernel at the moment .
have you tried reinstalling ?

Re: [Announce] kernel-power v48

nope,you mean i should uninstall kp48 which is showing in the Fapman and then again i should try to re-install that ? is that it what you tryna say ?

i'm not sure it will help , but seeing at what you have provided gave me the solution i have mentioned .
and as you have posted that you have multiboot installed , not sure may be multiboot creating a problem ?

p.s i am not a dev or any coder , so please feel free to ignore my post(s) :P

What is this I don't even. You can install the newer debs straight on top of the older versions. Immediately reboot though.

...'insmod ramzswap disksize_kb=32768' results in spontaneous reboot. Even without any custom kernel profile loaded.

Re: [Announce] kernel-power v48

I'm rewriting this post to make it more readable and informative.
My situation was: I had v46 + uboot installed, and wanted to update kernel power. But I wanted to keep uboot. (for meego)

Disclaimer: nothing in this post should kill kittens, but it may brick your phone. It worked for me, but may not work for you.
Also you should not write commands that you do not understand

Commands in this post come from here and there

What I did:
- deinstall uboot
- without rebooting, update kernel power (or force reinstall if you already have the latest version)
- reboot, to be sure (may not be necessary)
- flash the uboot version of the kernel, obtained by one of these two methods:

1) get it on my server

or

2) make it yourself using these commands:
this assumes
- a ubuntu box.
- uboot-mkimage is installed
- flasher-3.5 is in the active folder (and chmod +x)

Code:

#!/bin/bash



# change name for other versions

pkFile="kernel-power_2.6.28-10power48_armel.deb"

imName="Power Kernel v48"



#1. Download power kernel deb file from repository and extract fiasco image from it

wget http://repository.maemo.org/extras-devel/pool/fremantle/free/k/kernel-power/"$pkFile" -O kernel-power.deb

dpkg --fsys-tarfile kernel-power.deb | tar --wildcards -xf - ./boot/*

mv ./boot/zImage* ./zImage-power.fiasco

rm -r boot

rm kernel-power.deb



#2. Download Matan's u-boot from repository (it is named u-boot-for-power-kernel) and extract file image from it

wget http://repository.maemo.org/extras-devel/pool/fremantle/free/u/u-boot-for-power-kernel/u-boot-for-power-kernel_1.0_all.deb -O u-boot-for-power-kernel_1.0_all.deb

dpkg --fsys-tarfile u-boot-for-power-kernel_1.0_all.deb | tar -xf - ./usr/lib/u-boot/u-boot.bin.0x38000/u-boot.bin.0x38000

mv ./usr/lib/u-boot/u-boot.bin.0x38000/u-boot.bin.0x38000 ./vmlinuz-power

rm -r usr

rm u-boot-for-power-kernel_1.0_all.deb



#3. Unpack Fiasco image

./flasher-3.5 -u -F zImage-power.fiasco

rm zImage-power.fiasco



#4. Transform zImage in uImage (necessary because u-boot boots Kernel only in uImage file format)

mkimage -A arm -O linux -T kernel -C none -a 80008000 -e 80008000 -n "$imName" -d zImage uImage 



#5. Add power kernel uImage at end of previous file (starting write at offset 0x38000 aka 448 blocks)

dd if=uImage of=vmlinuz-power seek=448



#6. Remove zImage & uImage

rm zImage

rm uImage

chmod a=rw vmlinuz-power

Either way, you end up with a vmlinuz-power file. You can flash it (this flashes the kernel only, it does not removes your programmes or data) like this:

Code:

sudo ./flasher-3.5 -f -k vmlinuz-power -R

(to flash, turn off the phone, unplug it, launch the command, press and hold "u", plug the N900.. see "updating the firmware for details")

Feel free to give feedback or improve the script :)

A) You're quite late to the party b) seems qcpufreq has it's own issues, namely enabling VDD1/VDD2 c) guys like xterm but not 'apps'

Many thanks, erendorn.

So I take the vmlinuz-power file and what I have to do with it?

I want uboot to try meego.

Thanks in advance.

The graph of my battery-usage looks the same like what kp47 did, needs more days to get the big picture but I don't see any negative effects on battery life when going kp47 -> kp48

Edit - usual warning: backup, and be prepared to be forced to reflash (but it should work in most cases)

I'll rewrite the post in a more informative way latter, but all I needed to do with it after having installed power kernel v48 was:

Code:

sudo ./flasher-3.5 -f -k vmlinuz-power -R

(turn off the phone, run the command in linux, press and hold "u" on the device, plug the usb cable - adjust accordingly with your flashing environment - check "updating the firmawre" in the wiki)
it can also be done from inside the N900, see the second post I was reffering to.

As you are alredy using this kernel there are some alternatives to Joiko, that should work.

Re: [Announce] kernel-power v48

Guys,

A noob question: What's wrong with my environment, I have multiboot installed, when I'm going to install "Linux kernel for power user (boot image for multiboot) I get a conflict error with "Linux kernel for power user (1:2.6.28-10power47) and vice-versa when I'm going to install the Linux kernel for power user 2.6.28-10power48 it conflicts with the Linux kernel for power user(boot image)(1:2.6.28-10power47).

Should I uninstall the Linux kernel for power user (1:2.6.28-10power47)? How can i do that?

Hi
I aplied the update for the Kernel via FAPM and now every time I check conky to the freq it doesn't seem to fluctuate like it was before. I meen it's allways in the higher frequency, I don't want to frie my n900. Is this normall or there is something wrong? I also aplied Karam's patches. Thanks in advance for any help
