Hmmm...I'm sitting and thinking what kernel to use with JVK...
Supercurio's?
Hacked Lagfix/Ext4 Samsung Galaxy S Gingerbread - JVK
A well known programmer stands behind this kernel... Stable for sure...
Con: CWM 2, or maybe it's a pro for now?
He updated the kernel, you can now connect via adb in recovery.

Chainsfire's?
CF-Root 2.6
It's more like a stock kernel with root option.
- The kernel is fully stock and taken from the original firmware, with just the following added:
- Root
- Superuser 2.3.6.1
GINGERBREAD ( CF-Root >= 2.4 versions, JVK and newer )
---- Busybox v1.16.2androidminimal (from CWM)
---- Integrated CWM 3.0.0.5 / RFS

DamianGTO's?
DamianGTO Ultimate Ginger Kernel (Beta 3)
- Optimized kernel tweaks.
- Low memory killer minfree settings (60MB).
- Deadline schedueler (Optimized).
- Touchscreen sensitivity (High)
- CWM 3.0
- Auto Root (Busybox and Superuser)

The last two have CWM 3 injected, while curio's kernel using CWM 2.
CWM 3 has orange font color (speedmod-green, voodoo-red).
CWM 3 can be used to flash only updates.zip that contain edify scripting, so you won't be able to flash ie. current speedmod kernel in cwm version, but now Hardcore didn't come up with his JVK kernel yet.
You may find out if an update zip is CWM compatible by looking into META-INF\com\google\android\. If there are the below files then you may flash it in CWM 3:
updater-script
update-binary
In old ammend script updates you'll only see update-script file.
The only having sorta optimisations is DamianGTO's. But... I would love to hear your opinions. Which kernel is best for now, when no gingerbread kernel sources hasn't been released yet and no real hacking can be involved...
I vote for damian's kernel. Supercurio's kernel was unstable for me, but faster ofc. Using now damian's beta 2

Damian GTO is the best so far...
Wouldn't it be a good idea then to use the damian kernel for daily use and use the SGS kernel flasher to go back to voodoo when you need CWM2 for ROM upgrade....?
I have to vote for supercurio's lag fix off. Stable for me and smoother scrolling
Stock XXJVK, Voodoo GB hack Kernel, JVE GB Modem
Anybody wrote opinion about CF-Root 2.6 , please ?
Regards
I'm using Supercurio's kernel with lagfix enabled - haven't had any speed (surprise) or stability issues

CF-Root is just for rooting and CWM.
Supercurio's with ext4. Some things (market, for example) are MUCH faster than without ext.
With JVK I went with CF-root (for rooting, and a CWM3-only update) and then Supercurio's for general usage afterwards.
So far I've done the same with the new JVB-firmware and it seems to work very well. Any opinions on this now that we have a new firmware to play with?
Supercurio's still the best? Or does Damian's have an edge in other areas which Supercurio's doesn't address?

Hi,
Can I flash a froyo kernel to an eclair rom and vice-versa?
Will I loose/get fonctionalities?
What I want to do:
flash a 2.6.29 kernel(eclair) to a JPK rom to run voodoo on JPK (I will propably loose some fonctionality since its an *old* kernel)
flash a 2.6.32.9 rev6 (asian froyo dxJP1 kernel) to a JPK rom (to get better battery life and smoother flash since I tried JP1 for a week and it was stable and fast)
flash a voodoo modified kernel to any 2.2 rom to see what happens (but I am a little afraid to flash an oc/uv kernel to a rom not designed for it since it could maybe, under some circumstance damage the phone...)
Any ideas or tests already run?
I am gonna try the JP1 kernel on then JPK rom tomorrow to see if it works and if I got improvements from the JP1...

franklin01, this thread belongs in the Q&A section, not in development. Take a moment and read the "STOP!! Before you post, read this NOW!!" thread at the top of both of these sections, it has clear guidelines for proper thread placement.
Hi Guys,
I just got my Captivate couple days ago. I were able to unlock, root, get a new ROM (Cognition v2.3b8) and install some apps. I'm looking to get a new kernel for the ROM. How would I go about flashing it to a different Kernel like SpeedMod K12I ? Thanks.
Sgs kernel flasher app in market
To be safe always disable lagfix prior. App is very easy to user and quick

I am a noob here. But I am wondering what are/is the benefits/risk of replacing the kernel that comes with Cog v2.3b8 with another. I recently flashed Cog v2.3b8 from stock (batch 1006), and find this is pretty much as stable as stock. Only issue is with GPS (which was hit and miss on stock). So do the benefits of replacing the kernel in Cog v2.3b8 outweigh the risks?
Thankshttp://media.xda-developers.com/images/icons/icon7.gif
Well kernels have different features and abilities in them. It depends what you want from your kernel. Some might support BLN while others will have OC/UC or just OC. Various combinations of options. You just need to make sure that the kernel/ROM/modem are from the same family, etc. I9000 or Captivate. If you flash a i9000 kernel into a Captivate ROM you might have issues.
Cog v2.3b8 is a Captivate ROM I believe. You can flash Kernels which are for it.
cog runs fine with an i9000 kernel so long as you also use an i9000 modem. i can't run the i9000 roms because of service drops but this set-up is still very good.

If you want to install a new kernel over the existing kernel,
1. Download the Kernel from http://forum.xda-developers.com/showthread.php?t=893880
2. Go to CWM recovery. (directly or through ROM Manager)
3. Choose the zip from SD
4. Flash and Reboot.
Make sure that there is atleast one boot after the ROM is installed.
To confirm,
check Kernel Version in Settings-> About Phone

Well each kernel has it's own benefits.
For instance, Speedmod uses sztupy's Universal Lagfix unlike other Kernels that use Vodoo Lagfix.
The main differences would be in the speed and battery. Samsung uses 250hz (as default), firebird kernel uses 300Hz and Speedmod uses 500Hz. Doesn't change battery consumption much but provides more smoothness.
Then the RAM Available. It varies from Kernel to Kernel from 300-350MB.
Cappy Kernels are for Captivate Only because of reorientation fixes and button mapping.
Hope this helps
Is there a thread or site where all the different kernels are compared?
Thanks
Why don't you start one?
There are a few:
1. Hardcore's Speedmod kernel
2. Supercurio's Voodoo kernel
3. Lastufo's Super Optimized kernel (based on Speedmod)
4. Trasig's kernel (based on Voodoo)
5. DamienGto's Steam kernel (based on sztupy's original Steam module)
6. Tegrak's kernel (onenand mode)
7. Zenkin's YA-OK kernel (based on raspdeep's oc kernel) this should be discontinued already.
There you have it.

wrong. i don't use Sztupy kernel as base. i use Sztupy steam module in the recovery.
the kernel is all modified by me.
**DamianGTO Steam kernel. 350MB Ram. 500HZ. Ext2 on all partitions. js3 base**
Hm, it would also be great to have links to all of those kernels, their details and source code... Eg.:
SpeedMod - details http://forum.xda-developers.com/showthread.php?t=822756, kernel http://forum.xda-developers.com/attachment.php?attachmentid=511980&d=1297145484, cwm http://forum.xda-developers.com/attachment.php?attachmentid=511983&d=1297145637, source http://forum.xda-developers.com/attachment.php?attachmentid=512228&d=1297167793
Voodoo - http://project-voodoo.org/
...
I've used Hardcore's, Supercurio's, and Trasig's. Right now, I'm using Voodoo 5.4.1.
In my opinion each of the three (EXT4 lagfix applied) have their own benefits.
Speedmod is the best on battery but the worst of the three for speed. It's still fast, don't get me wrong, but the real benefit lies in the speed to battery-usage. Keep in mind, Hardcore's update schedule, it's; test, stable, test, stable, etc.
Advanced Voodoo is the fastest due to the overclocking ability. Truth be told, I didn't have this kernel on long enough to really test battery life (went to Darky's 9.2 and I read that some people were having issues pairing these two). I did, however, have a bit of fun with benchmarks when on stock JS3 and the word "niiiiiice" just seemed to pop out here and there. This one isn't updated as fast as the other two.
Voodoo, I find to be a good, stable, and decently fast kernel. It's between the two in terms of speed and has been a kernel that I have used and trusted for quite some time with my SGS. Supercurio has, as of late been putting out a lot of updates though, primarily for Voodoo sound. If you have the time to flash a new update at least once a week, you're good to go.
Hope I helped you guys out.
I use Speedmod K13A with JS2, and I am really pleased of itt...it only scores 980 in quadrant, but it is very smooth and fast and has a good battery life
i use speed mode always

Yes it converts data to ext4

I like cf root it's close to stock kernel.Every rom that i tried with voodoo has automatic ext4 conversion and i dont like that.I like to know what i doing if i want to convert i will do it not kernel.For me semaphore 1.2 is the best kernel.

I think you should flash the stock JVH first.
Using JVP (2.3.4) I had bluetooth issue with CF-Root, none so far with SpeedMod.
GPS was also not so goot with CF-Root, I'm gonna see tonight with SpeedMod
Has anyone done a quantitative comparison of battery life with different kernels?
I think every kernel has his own good and bad parameters so the difference between kernels depends of what apps do u use and what do u want from kernel...
So for someone it is Voodoo! For another one it's CF-Root and so on !!!

Hi everyone,
Need help on installing Voodoo Lagfix on my Sgs.
My device:
GTI9000
Firmware: 2.3.3
Build Number: Gingerbread.DXJV9
I had Voodoo Lagfix installed on Froyo, disabled it via Documentation (official Website) before I update the firmware. Somehow it didn't work after I updating to Gingerbread. Is there a way for me to re-active the Lagfix? Or is there an updates for Lagfix for gingerbread lately? Couldn't find the download link from the official website..
Your help is much appreciated.
Thanks.
The Voodoo kernel that you used for the lagfix on 2.2 isn't compatible with Gingerbread and is removed when you flash to it. Supercurio has a new kernel for ext4 on GB : http://forum.xda-developers.com/showthread.php?t=975349
There are a few other kernels around which have ext4("lagfix") supported in them(eg CFRoot, Fugumod)
The Voodoo lagfix won't work without the Voodoo kernel. When you upgraded to Gingerbread, you obviously reverted to the new GB stock kernel, and not Voodoo.. You can find several lagfix supporting kernel in the Android Development section here..
