I have a question to you guys (including koxudaxi of course ;) ) :

Which (and why) is the best I/O Scheduling possible about performance and battery drain ?

I tried them all but the "noop" one which is supposed to be the best on flash devices (saw that on wikipedia) but I really don't see any difference between switching..

Moreover, why "sio" is default scheduling ? is it supposed to be the best ?
[Galaxy Tab  Android Development] Alcibiade:
I have been using sio & ondemand (which is the default on overcome)

People seemed to prefer Smartass, but I kept on having issues with it so far the moment I don't use it

I haven't done much testing (If you run several Quadrant benchmarks you find out in the end that different governor & I/O are quite close in peak performance so i assume it's not the best way to measure the performance. As far as battery life si concerned it is quite time consuming and I didn't check)

So I am pretty much interested to have a look at some benchmarks / tests if you find some

Fellow Romans, I'm here to testify that I've successfully installed version .10 of excellent koxudaxi kernel on stock gingerbread; then turned to ext4 with chainfire's apk.

So far, so good.:)

I wonder if I should go for version .11 or .12 though. Anyone tried?:confused:
[Galaxy Tab  Android Development] nobleskill:
On my tab sio + ondemand is stable but not rocking my world if ya know what I mean.

Bfq + interactive or smartass give me the best user experience. Smartass can be battery hungry if your using it alot for long periods but it is the quickest to respond and is at full tilt within a fraction of a fraction of a second. This makes me happy.

Hunting or other activity related injury? Man I miss grabbing up a rifle and lining up the tin cans for some target practice... can't work on it or don't want too? ;-)

Hmm yeah I find myself contemplating an attempt on repairing my Xbox 360 or something... alcohol + 3am is not the time to be near motherboards... especially when it was finished and you have a screwdriver ready to pop that GPU bracket back on. Not sure how that was supposed to work either, to this day I can't work it out.. was a lovely bottle of walker blue though so... good with the bad and all... rrod repair, first time I've put a motherboard in an oven and god I hope its the last too!! Was fixed though after the bake.. and then it met Sid (chrome) B-)

Yeah wow... I need to find something to do after that ot dribble.. ;-)

Honestly I think its going to be alot slower with releases moving forward... was never the best take up with developers, the old tab, and I think its going to be downhill from here.. been fun though... maybe sgsii is next up to bat?

Never used any of those apps, and sorted them in my autokill list via my "Task Manager" app when sreen turns off.

Anyway those apps can't be really uninstalled in one click like all other, need some adb commands I guess as it don't want to be uninstalled from android directly.

Anyway I'am really happy with your 3.0.12 kernel, no issue as all, and genious battery life, now I'am less druged from my device, I use it something like 4-5 hours a day and battery remains at 60% or something like that so it's pretty cool there!

My Voltage Control settings are :

I/O Scheduler : deadline

GPU Governor : ondemand

1400 Mhz	:	0

1200 Mhz	:	-50

1000 Mhz	:	-100

800 Mhz	:	-100

600 Mhz	:	-100

400 Mhz	:	-100

200 Mhz	:	-100

100 Mhz	:	-100

Everything stable, no reboot at all, no F/C, nothing :)

How can you sending everytime those long texts from your GT ?? it's crazy :D I become lazy when I need to write 3 sentences there, and I prefer to turn on my computer!! lol, which keyboard are you using ?

[Galaxy Tab  Android Development] koxudaxi:
New test version

change log:

re-apply HZ and compiler flags patches.

battery adc voltage is 3.0v (default is 3.3v)

set UV to 1.6v for ram (default is 1.8)

For quick response -> change a frequency to 1GHz while the screen is touched(samsung set 800MHz)

i use sio and ondemand.

also conservative may be good for long battery life

new touch screen patch may solve slow response in conservative

if you feel battery drain, you should uninstall default samsung apps like 'socialhub'

heimdall:zImage_euro_3_0_13NEW!!

cwm:zImage_eur_3_0_13_cwm.zipNEW!!
[Galaxy Tab  Android Development] koxudaxi:
thanks my friend.

i didn't use command line for uninstalling apps. Tianium Backup can uninstall any app as root user.

it's very easy and it is free which alway help me.:rolleyes:

i don't like app killer which spend a few battery power.:(
[Galaxy Tab  Android Development] AndroidGX:
Ok thanks ! :) tried it but I really don't like, I prefer to stay with SmartKeyboard Pro finally :p (too bad for me!)

Glad to see your work back mate, I'am currently testing it, will check report in few days with pleasure!

I totally forgot that Titanium Backup have an option for uninstalling as root, it's ding the job perfectly, and now have Samsung Apps, SocialHub and ReadersHub uninstalled! ;) thanks for the tips mate! :)

see you soon!

[Galaxy Tab  Android Development] ezynow:
Hi koxudaxi,

Edit - downloaded and updated again seems to be working fine.

Whats the best way to upgrade cwm zip or heidmal flash or they exactly the same. cwm just overwrites old files.

Also do you know what factory reset does in cwm? What does it actually format? I read this is a no-no on custom roms, can u confirm?

So what partitions do i need to format to get rid of any stuff i might have installed (user apps + data). I want to go back to a "stock" state without the actual re-stocking process if u know what i mean.

Once i can upgrade properly i can test it :)

Cheers matey

It may seem strange, but I got with 13th (:D) kernel (no UV/OC) sometimes hlfbright screen which doesn't respond on tap or touch. Testing now, probably that was accident bug.

Hi,

I managed flash the kernel but have problem to convert RFS to ext4. When booted into CWM, an error has occurred.

What should I do now?

Thanks,
[Galaxy Tab  Android Development] 4exess:
Thanks Kox for .13

works great even smoother then .11 was

no app conflicts yet , stable and fast

no power drains (-1% over 14 hrs idle and like -30% in full throtle over 2 hrs)

16 or 32gb tab? 32s have this problem
[Galaxy Tab  Android Development] jourdan:
Hi, 4exess.

My tab is 16GB and does not have any external sdcard. Now have problem convert the rfs filesystems to ext4. :(

Regards,
[Galaxy Tab  Android Development] rainbow ng:
wonder, never hear 32GB tab, how come u find?

which tool u use for the convertion?

K's kernel base on Chainfire CF-root, so use Chainfire "ext 4 add-on apk "to convert the file system and MUST be trouble free.
[Galaxy Tab  Android Development] AndroidGX:
Yeah I tried them all but I really don't like :-( but I recognize that it's a very nice concept and that it can be very addicted :-) thanks
[Galaxy Tab  Android Development] nobleskill:
You must have an external SD card in when doing the conversion... 3gb free on it too.. seriously though what did you think it was going to do with all the information and store said backup if there is only the drive its converting?...

Think about it... work it back and it is.... logic...

EDIT: sorry for the attitude it was a **** move. Sorry. But you need a micro SD card in for the conversion I'm sure and depending on the ROM it may need one for good. A class4 4gb generic will do the job.

Good luckkkk

Clear!! LOL。。。Actually I'm thinking of this logic too but I saw some people also have this issue even plugged in an ext sdcard.

So, to convert to ext4. we need a sdcard with at least 3gb free space. Insert it and format it with? :D

Thanks,
[Galaxy Tab  Android Development] ezynow:
Hi koxudaxi,

after re-downloading & installing latest kernel all is running nice now.

Should mention i am on the latest setcpu version with oc / uv control. Deleting voltage control app and system seems more stable with slightly more uv settings applied :cool:

Also i found my tab does not like scaling up to 1.4 oc so now on 1.2 oc and my tab feels a lot smoother. Although this could be some sort of placebo.

Thanks for this kernel, looks like a keeper :)

Anyhow, if you feel like a bit more tweaking, it seems cm7 has got a few nice features. One that is pretty useful is that landscape mode is working in apps such as connect bot. In all other roms only portrait mode works correctly. So if you have time u could look into this one if not i must commend you on ur efforts thus far.
[Galaxy Tab  Android Development] rainbow ng:
Sorry , I think you is 233, sorry!

for 2.2, no need to format, the space is for temp storage for conversation
[Galaxy Tab  Android Development] jourdan:
is alright brother.. i m still new to this, never flash any kernel or rom before. anyway, thanks for your guide. cheers!
[Galaxy Tab  Android Development] jourdan:
noted with thanks. :)
[Galaxy Tab  Android Development] koxudaxi:
hi,ezynow

thank you for your replay

i'm interested in cm7, but i must re-flash all rom.it is very difficult on me. i must develop and test for stock rom and more rom like overcome.

i will try it some day...
[Galaxy Tab  Android Development] nobleskill:
If your Tab is a gsm one? You should go have a look at the overcome ROM and kernel called Hermes. They have taken alot of care to write a really good guide for beginners and ill freely admit I might even a copy ready for a little back up"just in case" but I'm running overcome ROM with this kernel and its a great combo. The idea being get setup on overcome and then it's super easy to just flash this when it all makes a little sense.

I think most people in here would be running overcome? And kox 's kernel.

Sent from my GT-P1000
[Galaxy Tab  Android Development] koxudaxi:
i think you are right. overcome kernel is very great rom for GSM tab.

Now ,i am not using overcome for supporting stock rom.

but, i like his rom which have good things for us

And he is the man who supply many people a book for guidance:)
[Galaxy Tab  Android Development] rangercaptain:
Nothing!

Insert it and boot into recovery, then flash your kernel zip file.

Nothing to format.
[Galaxy Tab  Android Development] rangercaptain:
I use stock gingerbread rom and koxu's kernel. I don't use overcome rom.
[Galaxy Tab  Android Development] nobleskill:
I think its just ext4 that's the issue so i just noticed the no external SD and remembered you definitely need one when doing a rfs ->ext4 conversion.

I assumed there was already a custom ROM if cmw is being used but I think I may have assumed incorrectly?

J what are you currently running? What do you want from your Tab? Im on overcome now because I find its a good mix of stock and new and has some pretty themes for it. With it or this kernel I get the HD vids and good battery life. #1 +#2 on my list. I know someone on here using the cm7 as its got the feature they want. Cap here is staying as close to stock as possible by sounds and that's what suits his use. You may not even need ext4 to enjoy your tab. B-)

Sent from my GT-P1000
[Galaxy Tab  Android Development] jourdan:
Thanks, Captian. :)

Hi, Nobleskill.

Thanks for the advise. Ya, I'm using GSM tab with stock froyo + koxudaxi's kernel (froyo version). I know the overcome ROM and its kernel is great and it also have very straightforward guide for noob user like me.

Actually I'm very interested with spacemoose1 & ssserpentine's honeycomb port and I heard that the gingerbread bootloader have compatibility issue with Honeycomb, that's the reasons why I'm hesitate to go with it. I know that the ginger's user can still go with honeycomb once they downgrade to froyo again but it's just too challenging for me. :eek:

However, I have just make a "ghost" backup for my tab with following command just in case I want to roll them back again.

adb shell su -c "dd if=/dev/block/bml1 of=/sdcard/boot.bin bs=4096"
adb shell su -c "dd if=/dev/block/bml2 of=/sdcard/pit.pit bs=4096"
adb shell su -c "dd if=/dev/block/stl3 of=/sdcard/efs.rfs bs=4096"
adb shell su -c "dd if=/dev/block/bml4 of=/sdcard/Sbl.bin bs=4096"
adb shell su -c "dd if=/dev/block/stl6 of=/sdcard/param.lfs bs=4096"
adb shell su -c "dd if=/dev/block/bml7 of=/sdcard/zImage bs=4096"
adb shell su -c "dd if=/dev/block/stl9 of=/sdcard/factoryfs.rfs bs=4096"
adb shell su -c "dd if=/dev/block/stl10 of=/sdcard/dbdata.rfs bs=4096"
adb shell su -c "dd if=/dev/block/stl11 of=/sdcard/cache.rfs bs=4096"
adb shell su -c "dd if=/dev/block/bml12 of=/sdcard/modem.bin bs=4096"
adb shell su -c "tar -czvf /sdcard/data.tar.gz /data"

adb pull /sdcard/param.lfs .
adb pull /sdcard/zImage .
adb pull /sdcard/factoryfs.rfs .
adb pull /sdcard/dbdata.rfs .
adb pull /sdcard/cache.rfs .
adb pull /sdcard/modem.bin .
adb pull /sdcard/efs.rfs .
adb pull /sdcard/boot.bin .
adb pull /sdcard/Sbl.bin .
adb pull /sdcard/pit.pit .
adb pull /sdcard/data.tar.gz .

With the files that I've backed-up, I might go for Overcome's rom to taste the gingerbread and also the combo as suggested by you. :D

One thing I would like to confirm with you guys,

Can I just use odin or heimdall to flash the above backed-up files in order to roll back to froyo from gingerbread?

What about the filesystems? any problem to run the stock froyo and kernel on ext4 filesystems?

Thanks in advance for your help! :)
[Galaxy Tab  Android Development] rangercaptain:
There is a froyo version of overcome.

If you can do that back up using adb, what are you worried about? You have mad skills.
[Galaxy Tab  Android Development] jourdan:
Hi, Captain.

With the spirit of android geek. I am moving forward to "meet" gingerbread. :D
[Galaxy Tab  Android Development] nobleskill:
Edit: just noticed the tar is done so you are sweet. The tar for Odin and the single files for heimdall

+1

That's a roto backup almost! Just missing tar on device but wow. You fooling with us, pretending to be n00b.. lol.. I must say I have been super keen for honeycomb too but I won't jump ship till its a usuable everyday setup. I think that's still a ways off. You might see benifit in dip7s ROM aswell. Its a snappy asian based one so has the Eurasian locals and language. I'm in Australia but it seems to really like my tab so I'm just about to jump on to it after a clean out this time.

I would recommend getting in on a gingerbread ROM as ssoon as possible though. The differences are amazingly noticeable and there are a few to choose from. Technomancers cm7. Very nice ROM but is not suitable for me as a daily. Dip7s one and overcome. Also chainfires stock GB would show you just how good it is. The way I look at it if i can't have a proper honeycomb now and as it looks to be a little down the track before it's really ready I want the latest version of the os that is practical so as to get that little extra from the tech.

OK so yes those files are good for heimdall but need to be tar balled before iodine will really like em. Um, I suspect you will be able to work that out though. :-D best to just do it on the device too. Roto-backup and roto thread on that will help if you get stuck. Be wary of flashing the bootloaders unless you really have to. Its kinda the easiest and only way to perm brick your tab afaik .

I tdont think the true stock ones will work with ext4. Most if not all custom ROMS will though but that would be something that would be known on a ROM by ROM basis from the release notes.

[Galaxy Tab  Android Development] jourdan:
The backup script is actually roto's script. I'm really a n00b. Anyway, thanks for the explanation and guidance. I'm really appreciate it. :)

Now, I'm going to flash overcome rom.

Good luck to myself! LOL

- Now I am on gingerbread. Will try the other kernel including koxudaxi's kernel as well.
[Galaxy Tab  Android Development] koxudaxi:
i feel good about 3_0_13 which is stable and very smooth:)

but, i should make a kernel of next stage. i think galaxy tab is great device which can grow up.

do you have a request in my kernel?;)

i ask you ...what do you want on galaxy tab? you need new function on tab?

do you hope more speed on one? long battery life?

also other android device may have good function . i'm looking for new idea....
[Galaxy Tab  Android Development] cromed:
Hi master koxudaxi! Before of all thank you for a great kernel and of cause for your work.

Here are my sugestions (I think will be cool to have such futures):

- Overcome CwM Recovery 4.0.0.2 instead of default CWM 3.0.0.5 (sources are available on Overcome team site)

- Two versions of your kernel (one for maximum performance and one for long battery life) - this is only my opinion

That's all. Thanks!

Hi koxudaxi,

I feel that from the 3.0.10 kernel series the autobrightness is broken...

it only works two steps (dark/light)...

could you fix that?

or is something related to the sensor module not working with the patched kernel?
[Galaxy Tab  Android Development] theerachai:
I don't have this problem

3.0.13
[Galaxy Tab  Android Development] AndroidGX:
Ok time for a little review about the 3.0.13:

- Battery drain : this is exceptional ! better than 3.0.12 (gain is like 10-20% better when finishing my day). Fantastic job ! :cool:

- Performances : Nothing changed, everything is ok and very good ! but I saw a huge down on bluetooth transfert, which is very low now, will try later if it's not the device of my mother that I tried but on 3.0.12 I think is was better.

About the idea above, I think I prefer to have 1 kernel which regroup performances and battery drain at one time, because flashing 1 for performances and if you want back to battery saving to flash another one, we will lose many time :(

Last thing, I finally saw something interesting here, I thought the stuttering sound I get while listening to musics on my GT was due to the "Equalizer" app which had too many bass effects, but it wasn't ! I tried listening with "Conservativ" governer and everything is finally OK ! no more stuttering/crashing sound. But when I turn on again with "Ondemand" or "Smartass" gov, they are back again.

Would be interesting to see what going on about that on differents gov and see why it do not this on "Conservativ" gov and others one yes. And why not, porting that thing into Smartass and Ondemand gov ?

Again, many thanks for your great job mate koxudaxi :cool:
[Galaxy Tab  Android Development] OsitKP:
Have you checked BT transfer speed with conservative gov? Any difference?

Does the battery drain differs with ondemand and conservative?

Thanks.
[Galaxy Tab  Android Development] triplex76:
mmmmhhh, maybe the issue comes from the light module .... the one I changed to get the light buttons working properly ...

do you got ginger "normal" button lights behaviour??

when the display light is on... the light of the buttons is on too?

or did you apply the patch to get them switching off after 5 seconds just as on froyo?

just asking to find the culprit

[edit]

problem solved

found the culprit...

it was the custom framework modded to get th battery % in the status bar...

once back to the original one everything is good

ops, the framework I got is not the original but it's the JPD one ...

could somebody upload the original JQ framework?

thanks ALOT!!

nevermind found it!
