to rainbow ng

I use your zip file

still autoreboot at screen off

my rom is your sky7.03

so I use back the CF-Root
[Galaxy Tab  Android Development] rainbow ng:
I am trying back to 3_0_0, no reboot occur at screen off now but no smartass avaiable....

odlin format 3_0_0:
[Galaxy Tab  Android Development] triplex76:
Hi koxudaxi ! how do you do? hope well ...

about the smartass bug ... I found that if there is busybox inside xbin directory it does not work ... as soon as you delete busybox it start working ...
[Galaxy Tab  Android Development] dave18:
Thanks.Tried it.Quadrant score now 2000 (for what is worth-lol)
[Galaxy Tab  Android Development] koxudaxi:

For heimdall

http://koxudaxi.sakura.ne.jp/android/zImage/zImage_eur_3_0_2

change log:

add 600MHz

uv by under voltage.app is in top page on this thread

fixed a few bug

thanks to netarchy who give me patches.

https://github.com/netarchy/nexus-s

i understand about auto reboot bug.

chuan_j give me autoreboot bug report

if you install cpufreq modules then your tab will reboot over auto

if you use my kernel ,you should remove cpufreq modules in /system/lib/modules/

@zetsurin

no problem. if you flashed euro modem on your tab , your tab become sim free phone.

i tested that i flashed euro modem.bin on my tab and inserted TIM(Telecom Italia Mobile) sim card . my tab could can get 3G radio in japan.

@ssserpentine

3_0_2 have 600MHz.

Please try it.

@rainbow ng

if you install cpufreq modules then you should remove it.

it will conflict when you don't remove modules

@triplex76

oh,than you

i don't understand why busybox is deleted

i reinstall busybox in /sbin

@cx5

i think i must study english .

i know it is important element that practice, practice,practice...:)
[Galaxy Tab  Android Development] ravindrank:
great

@koxudaxi

You are great... After reasing ur threads..I just setup Android sdk and cross compiler.. To start with compiled the default 2.3.3 kernel successfully..

Trying ur kernel now :)
[Galaxy Tab  Android Development] ravindrank:
Ok.. switched to a non smart ass scheduler...looked for the old modules in /system/lib ... renamed the cpu modules to oldname.1.. removed apply at boot option..

backed up sd card :) (which has nandroid backup, tb files)

flashed ..rebooted.. all well.. switched to smart ass... no probs so far.

observing....
[Galaxy Tab  Android Development] ravindrank:
Ran Quadrant.. (not for the score) Just to see if all runs well.. score is 1550 though..
[Galaxy Tab  Android Development] ravindrank:
Tested UV.. Got a reboot.. Master Koxudaxi.. do you want me to send any logs? :)
[Galaxy Tab  Android Development] speldenaar:
Just flashed through cwm. Kernel root@hp-deb #1

I'll post my findings.

Thanks so far. Your work is highly appriciated!
[Galaxy Tab  Android Development] ravindrank:
OK.. there is some bug in setcpu.. the speed was still at 1 ghz.. had to lower it and then choose 1400...then it works.. Quadrant score 1708...

OT:How do we convert the root fs to ext4 ?? :D
[Galaxy Tab  Android Development] Gpsrisk:
Master kux,

Rebooting still persist under E3.0.2 even without installing setcpu.

What cud b the problem?
[Galaxy Tab  Android Development] rainbow ng:
Koxudaxi,

after deleted the /bin/modules/cpu_frequency and

/etc/init.d/90

auto reboot gone and the 3_0_2 oc kernel work well.

You are right. conflict occur when Mr. X script present inside /system.

Odlin version: OC-kernel_3_0_2.tar

edit: the kernel make Touchwiz4 as smooth as ever before!! XD
[Galaxy Tab  Android Development] nobleskill:
Yup confirmed here as well. Great work mate thank you for all the hard work.

I can also confirm shaded issue in quadrant and that interactive seems more stable than smartass for the time being.

Loving it though. Has helped with my flashing addiction having these to play with.... ;-)

Sent from my GT-P1000
[Galaxy Tab  Android Development] zetsurin:
Careful, you know you can get arrested for doing that :)
[Galaxy Tab  Android Development] patomas:
Me too. I get a reboot setting any value of UV. Which app should we use to UV?

I downloaded the gt-600 one from the first post.

Thanks!
[Galaxy Tab  Android Development] d34d4liv3:
Tested ok.
[Galaxy Tab  Android Development] waazaii:
i use overcome rc1 can i use these kernal..
[Galaxy Tab  Android Development] rainbow ng:
what uv values you use ? can't see the figure....

will reboot if setting more then 3 item in the voltage control.
[Galaxy Tab  Android Development] fastcx:
Any UV value over 75mV will get reboot
[Galaxy Tab  Android Development] ravindrank:
Thanks for the interesting observation.. will try it
[Galaxy Tab  Android Development] ravindrank:
Tried with only 75mv.. didnt work,.., still reboots.,.

Also.. The voodoo sound control app doesnt seem to recognise the voodoo enabled kernel? any one else seeing same?
[Galaxy Tab  Android Development] triplex76:
it reboots when display light switchs off

vodoo sound support is not included in this kernel so it doesn't work
[Galaxy Tab  Android Development] triplex76:
Koxudaxi I think you need to ask the moderators to modify the thread's title including the gingerbread OC/UV support cause at the moment most of us still doesn't know about the GB kernel born
[Galaxy Tab  Android Development] fastcx:
How about 50mV?
[Galaxy Tab  Android Development] cx5:
Hi koxudaxi-san

no no, pls don't mis-understand.

I was just making a joke by using the bear, sounds like watching a national geographic episode of a bear sleeping in winter, hope to give everyone a laugh, happy.

Obviously my joke very lousy, looks like I'm the one who need to learn English. Hahhahaha.
[Galaxy Tab  Android Development] rainbow ng:
Still the case, may be need master to see what happen to the UV.

Would you mind to take a look of this hack kernel for I9000 2.3.3 with voodoo lagfix by Supericuro
[Galaxy Tab  Android Development] d34d4liv3:
Im using 75mV for 100,200&400, 50mV for 600&800, 25mV for 1000&1200. Everthing ok. No FC. Quadrant test still above 2k.
[Galaxy Tab  Android Development] koxudaxi:
thank you

i just edited the title on this thread:)

i show uv setting

i used this setting today which is very stable!!

did you remove any Mr.X's file?
[Galaxy Tab  Android Development] ravindrank:
San koxudaxi...yes this setting worksfine :)
[Galaxy Tab  Android Development] d34d4liv3:
Tested wt koxudaxi setting. Rom still run smoothly wt >2k quadrant. Thanks. Looking forward for voodoo next.

How do I delete modules (smartass etc)

I tried using Astro no go , also tried Android Commander on PC and no go.

USB Debugging is enabled btw
[Galaxy Tab  Android Development] dave18:
I was stuck on endless reboot cos i accidentally set uv settings to boot.Had to reflash overcome and your kernel. Installed uv app and now using sensei's uv settings. So, all is well.The reflash got rid of all conflicting files. Thank you.
[Galaxy Tab  Android Development] roy8846:
I know what to delete just dont know how...

I can adb but not sure of the commands etc.

I tried Android Commander (PC) but it wont delete anything??
[Galaxy Tab  Android Development] ravindrank:
Hi,

Please install Droid Tweaker & Yaffs file manager...

1. launch Droid Tweaker.. Mount Root fs in Read Write mode,.

2. launch yaffs file manager.. Navigate to the folders/file and now you should be able to delete...

cheers:)
[Galaxy Tab  Android Development] OsitKP:
Or do the same using Root Explorer only. :)
[Galaxy Tab  Android Development] ravindrank:
OT: @Koxudaxi san Is there any advise on how we can convert from rfs to ext4 as your kernel has ext4 support in gingerbread? sorry for asking here .. but my guess is.. you have already tried and would have some answer or suggestion..
[Galaxy Tab  Android Development] roy8846:
Thanks for the help guys.

Thanks for the kernel as well!

Is it really ok to uv as far as -200?
[Galaxy Tab  Android Development] koxudaxi:
i'm sorry, everyone

it is NOT really ok.

this uv patch has a bug which can't correct control voltage.

i'm making a fixed kernel.

please wait...

sorry, i have not tried it yet...
[Galaxy Tab  Android Development] ssserpentine:
hello,

thank you so much for including 600mhz scaling. now smartass has no problems....kinda unstable still. Smartass revs through all cycles, instead of staying lower. I know you know it doesnt scale correctly.

I need your help tho.....

can you please attempt to help me step up my scaling? even 1mhz more would help. Alot

I need this added speed to test and port things that require tegra2. Alot of them are very intense, and having added speed on my tab would speed the process up greatly.

I am trying to get these things to run on stock 1ghz, but need the speed for testing as I go.

thanx

plus 1 for the 600mhz scaling.

heimdall:zImage_euro_3_0_3NEW!!

cwm:zImage_eur_3_0_3_cwm.zipNEW!!

i just build new kernel .the bug was fixed.

this kernel scan really voltage on voltage tables.

if you already use voltage control app(VoltageControl-gt-600.apk), first you should uninstall it.

you can get new version on the market .

the name is "Voltage Control Lite" which can read stock voltage values on this kernel.

it's 4:31 am ...i must sleep ;)
[Galaxy Tab  Android Development] roy8846:
All seems good so far.

Thanks Again For Your Hard Work!!!

Euro 3_0_3 CWM kernel

Will I need to remove Mr. X files if I used the new cwm:zImage_eur_3_0_3_cwm.zip kernel?
[Galaxy Tab  Android Development] shoe5428:
I update the 3.0.3

The same UV setting make the screen cant open when screen off

so I back to 3.0.2

Should I change which freq voltage

Tks
[Galaxy Tab  Android Development] OsitKP:
I dare to say "Yes". It was necessary for 3_0_2 kernel. The more Koxudaxi wrote to uninstall previos version of UV app.
[Galaxy Tab  Android Development] Gpsrisk:
MAster Koxudaxi,

which is this Mr.X's files? where do i find it and remove it? :(
[Galaxy Tab  Android Development] Gpsrisk:
Where is this MR.X' files ? what are the files actually? :confused:
[Galaxy Tab  Android Development] lilstevie:
can I suggest a patch to use :)

patch s3cfb.c to fix graphical corruption with ginger kernels on froyo bootloaders
[Galaxy Tab  Android Development] cx5:
Hi rainbow ng, good idea :)
[Galaxy Tab  Android Development] OsitKP:
If you haven't applied Mr.X's patch (http://xdaforums.com/showthread.php?t=1085441), you needn't worry. If you have, than at least delete file: /etc/init.d/90modules.
[Galaxy Tab  Android Development] ravindrank:
3.0.3 works fine.....used new app for uv...still got freeze up n reboot....
[Galaxy Tab  Android Development] nobleskill:
Really?? Mate how about we go back some posts and read up.... its still a beta kernel and the link provided to the UV apk is fairly clear that you need it and need to uninstall the previous apk.

Your statement is useless. You provide no information about out any of the many variables required to advise you... what settings are you using in setcpu and what UV settings are you trying to run? Did you consider trying some different voltage settings as all tabs are different in what they can tolerate?

Dude show some respect to the developer, the site and the rest of us and atleast make the effort to fill more than 1 line when you are claiming something doesn't work...

EDIT: Just to be clear too. I am using the UV apk posted. I have been playing the UV settings and have not yet had q freeze/reboot or even any instability. Been watching vids, camera, web, here and really have found it to be a fine beta. My advice is to start @ 25 and move up from there untilled you find what is tolerable for your tab.

Sent from my GT-P1000
[Galaxy Tab  Android Development] Gpsrisk:
Thanks and yes i did not apply Mr.X's patch. I took the guts and tried deleting a file named S_volt_scheduler and E3.0.3 was successfully installed. Thanks.

Guess i might have saved the voltage setting under reboot which caused S_volt_scheduler to be generated.

And one more thing i had experienced .... we should not save the voltage setting under reboot until we are sure what are the correct and acceptable values...else when rebooting ...GT freezes when booting.:confused:
[Galaxy Tab  Android Development] eliotpoon:
I tried to flash the latast version for 2.3.3 through CWM. However, there is a boot loop during the boot animation. I have uninstalled the voltage control before. Anyone knows why this happen? Thanks in advanced.
[Galaxy Tab  Android Development] ravindrank:
Ok...using voltage control lite from market...had already uninstalled the alpha version after readinv prev posts..used setting suggested in prev posts..

Yes I read... and I have great respect for everyone (not only devs) in this forum...im not conplaining..just trying to test n post some feedback...

Thanx for the great kernel!
[Galaxy Tab  Android Development] perling:
What is better smartass or ondemand ?

Anyone have told me that high uv damage the sgt more than low uv is this right?
[Galaxy Tab  Android Development] greenbat:
ondemand or smart ass

With smart ass I can see in setcpu CPU speed jumping around from 100 to 800 to 1400 Mhz without doing anything (=idle).

With ondemand when idle it stays rock stable on 100 Mhz, therefore I have excellent battery life.

Benchmarks scores might be lower with ondemand though

Overclocking (OC) can give damage, undervolting (UV) not, however may cause (severe) crashes and reboot loops!
[Galaxy Tab  Android Development] perling:
Ok thanks you
[Galaxy Tab  Android Development] MarlowXim:
Really nice work was going to make an oc kernel until my laptop hard drive crapped out.the only thing I suggest is patching the touch lights so they time out neldar has already a gb patch set available. Some additions you can add is cfq for small files and patching arm with optimized rwsem algorithm and some armv7 patch sets you can look in existz and fugumod source trees under i9000 and captivate respectively.

Also I'm surprised this chip can handle such higher voltages this usually craps out on galaxy s series.

Keep up the good work!
[Galaxy Tab  Android Development] 09CarreraS:
I installed this kernel several times. It keeps boot looping on me. I deleted the 90modules in the init.d dir. It booted once then locked up. It keeps boot looping. Can anyone please help?
[Galaxy Tab  Android Development] fastcx:
Have you deleted the UV script as well? S_volt_scheduler. Just to make sure it's not the UV setting. If you didn't had that in the first place, perhaps clear cache in cwm
[Galaxy Tab  Android Development] OsitKP:
Right you are! :D

I'd add that saving settings of UV is acceptable ONLY when all modes are tested. For example, my tab worked fine till I start moboplayer, so I had to low UV values.
[Galaxy Tab  Android Development] crysalis786:
To Koxudaxi,

This kernel is very good. I used it with the overcome froyo rom. However I have now migrated to the GB CM7 beta ROM. Will this kernel work with this CM7 rom? I may attwmpt it at some point today ( nandroid backup will be a must prerequisite!). If someone else has tried it then please let me know of the results. Thanks to all especially OP.

As I mentioned in the CM7 thread I have been getting quadrant scores of 2300-2600 regularly with that rom and its default kernel. Now I know these scores don't necessarily mean much when comparing devices but when comparing various roms on the same device. I guess as long as the kernel developer doesnt artificially manipulate the kernel to do well in these benchmarks.then i can use it as a general guide to see how the tablet is performing. I do look forward to what an overclock kernel can achieve in this regard.

Furthermore, I know that my tab can handle quite substantial undervolts as I have done this in the past. So this can help significantly in extending battery life. Also if additional frequencies are added or alternative governors then this too can establish a smooth performing device with extended battery life and therefore usage time between charges.

Keep up the fantastic work and I congratulate all developers for their achievements thus far!
[Galaxy Tab  Android Development] OsitKP:
Go to the post 517. The links for GB Kernel are there.
[Galaxy Tab  Android Development] :
also in the op post (page 1, post 1) ;)
[Galaxy Tab  Android Development] siggehandf:
Hmm, installed this kernel and the ext4 convert. It works fine, except, now I don't have root access, superuser app just crashes. I tried doing superclick, but it seems to be stuck at "running psneuter".

Any tips?
[Galaxy Tab  Android Development] crysalis786:
Unfortunately I tried to install the GB kernel on CM7 and now my tab is bootlooping on the initial samsung galaxy tab loading screen. The clockworkmod recovery is unable to restore my backup as it could not open the directory. I will try and use hiemdall to restore the kernel and or the Rom and then restore the backup. I tried fixing permissions etc and nothing worked so I guess that's that. The cm7 rom must be using a distinct/unique GB kernel.
[Galaxy Tab  Android Development] sephallen:
After the last two gingerbread updates I haven't been able to mount my internal SD card in cwm.
[Galaxy Tab  Android Development] crysalis786:
Update:

Fortunately.I could reflash the cm7 kernel and boot.the.tab, however wifi was not connecting properly and I restored my nandroid backup and everything is back to normal now. I don't know whether anyone else had similar issues to myself so I can't confirm whether it is my device/configuration or whether this.GB kernel is actually incompatible with CM7. Thanks to the developer anyway, but I think I will wait for a OC/UV CM7 kernel.
[Galaxy Tab  Android Development] Sneekapim:
I finally flashed back my GB to oc/uv Overcome, as there was no way to get any rom booting after applying ext4 converter (yes, did not reboot after convert, installed full overcome rom first, then directly flashed koxudaxi's kernel, then rebooted).

Tried all methods, Odin only, Heimdall only, direct cmw flashing, I never got the tab booting on ext4.
[Galaxy Tab  Android Development] koxudaxi:
i think cm7 is special rom which is different common rom

if you want use oc kernel on cm7 , the oc kernel must be compiled from cm7 source code.

i will try to apply this oc patch on cm7 when cm7 become stable
[Galaxy Tab  Android Development] Sneekapim:
@koxudaxi

in post #480 you said "if you flashed euro modem on your tab , your tab become sim free phone."

Well, I flashed euro modem and I can't get my Sim to be recognized :eek:

Is that what you were talking about?

Edit:

Ups, I can't get Wifi to run either Oo'!! What can that be?
[Galaxy Tab  Android Development] koxudaxi:
what do you have carrier?

i may misunderstand about modem.bin

my tab sim locked on ntt but i think euro modem can unlock one

btw my tab can't convert to ext4. it can't boot after i run convert_ext4.zip
[Galaxy Tab  Android Development] af974:
You must flash again your kernel with heimdall after conversion.

Btw,you need to format /system /data and cache with cwm mount and storage.
[Galaxy Tab  Android Development] koxudaxi:
oh,nice

i did not format for any partition.

btw do you feel very difficult to apply?

i want include this script in my kernel...
[Galaxy Tab  Android Development] af974:
I did it at first try and having it included in kernel would be much more simple to apply.
[Galaxy Tab  Android Development] OsitKP:
Koxudaxi, if I got you right, one of the easiest ways to convert rfs to ext4 is Chainfire's application: http://xdaforums.com/showpost.php?p=12651371&postcount=7

After starting app you choose "Convert", Tab reboots in CWR mode and convertion begins.
[Galaxy Tab  Android Development] koxudaxi:
maybe i understand why i can't convert /system to ext4 .

i type "df -h" in recovery mode

Filesystem Size Used Available Use% Mounted on
/dev/loop0 318.7M 302.0M 16.7M 95% /tmp/bksys
/dev/block/stl9 309.9M 9.9M 300.0M 3% /system

loop0 is mounted system.rfs image file with loop back option

stl9 is formatted /system with ext4

ext4 partition is too small...

i can't copy all file to ext4 partition.
[Galaxy Tab  Android Development] af974:
Koxudaxi,

Roddick did upload a version with a minor fix due to a problem found in metainf, would you like ti give it try?

I'm not on my pc and i cant use heimdall.
[Galaxy Tab  Android Development] ravindrank:
You rock! Thats an amazing tip..just converted and rebooted using cf ext4 tools...seems all fine..let me come back with more details...
[Galaxy Tab  Android Development] koxudaxi:
my version could not need heimdall.

i think we should disable journal for capacity

Roddick's zip don't disable it

Chainfire's convert tools support to disable junrnal.

many people say super user apps disappeared on tab

super user is installed to /system/xbin

a b c d e f.....x

i suppose restore command couldn't copy a few file..

also super user re-install to /system when we re-flash the kernel

but, if /system don't have free space then it can't install superuser app.
[Galaxy Tab  Android Development] af974:
That's should explain why i didn't lose my su permission, my own custom rom had less files in system than overcome.
[Galaxy Tab  Android Development] warm.shine:
easy way , my friend

before backing up on cwm.

just delete some system app like "live wallpaper、wallper"

then you dont have to delete journal
