Choosing the right kernel

Hi all,
My Galaxy S i9000 will arrive tomorrow and I'd like to be prepared how to and which kernel to flash.
I'll probably just flash JVQ, the latest official Gingerbread 2.3.4 ROM. But I can't decide which kernel to use. My main priority is the performance and safety (by this I mean recovery options).
I have found two kernels which might fit my needs.
First of all SpeedMod Gingerbread. It has EXT4 lagfix and sound improvements etc. It seems good to me.
There are no instructions for this one, but my guess is to just flash the .tar with ODIN as PDA?
Second I have found CF-Root. There are clear instructions so I don't need help how to, but is this a good option as a kernel?
What kernel do you think is the best for the Gingerbread ROM JVQ?
Also, what about CWM? How do I boot into this recovery? Does it replace the default recovery?
Sorry for the noob questions, but as you see I'm quiet uncertain about these things, though I've read alot.
Thanks

Stock JVQ ?
Why won't you flash a custom ROM ? For example you could install Insanity's, Darky's, etc... which are sort of "packages" containing everything you are looking for.
Each one of them have a specific forum in Dev, with flashing explanations.
As for kernels, if I ever needed to change, I'd go for Glitch.

I would wait and use cf root when its released and if your not happy with the speed then use an oc kernal.there are many packages that will be available for all the mods you want in the themes section.this way you will be as close to stock as possible avoiding any unwanted issues

I've considered Darky's 10.1, but I dunno, I don't like the green colors and everything.
Insanity and glitch look cool. I must have overlooked this ROM, I might consider it. Thanks for the tip
Stock with CF-Root seems to be the fastest in Quadrant. I'm in doubt.

bro i think u have to keep Cf-root i install jvq and put Speedmod in it but u cant image it doesnot contain Superuser and cmw after that i install Cf-root it really better then speedmod this time not always.........i hope u can go with cf root

Have you considered other kernels like Semaphore, Galaxian or Talon?
All of these have OC/UV capabilities, EXT 4 and more performance tweaks than CF-Root itself.
Speedmod is currently undergoing major developments (less stable versions being tested). You can wait until it has a stable version before flashing.
And you can buy Voodoo control plus if you want great sound.
I know Talon has Voodoo sound v9 built in. So, take your pick

For stock JVQ I recommend to use stock kernel until the custom kernels have updated JVQ initframs.
Sent from my GT-I9000 using XDA App

I'll look intro Talon. I won't overclock my device as I want it too last as long as possible The Voodoo stuff seems interesting. Would it work if I just flashed it over CF-Root? Guess not. I would have to flash the stock kernel and then Talon again?
With the latest stock JVQ I'm getting 1400 score in Quadrant, kinda low. I'm now attempting to convert to ext4, but the system folder has too less space, trying to move some apps.
Edit:
With everything converted to ext4 I now have 2300, that's better I'll leave it like this I think. I'm fine. Thanks for the tips

In that case i would recommend to use Talon 0.3.1 without OC.

try galaxian kernel for jvp and feel the speed...

yep, use Stock JVQ 2.3.4 (not deodexed! many errors: phone and browser fcs) and galaxian kernel.
My SGS is flying with that combination

damian kernel flies with jvq and has what you want scores of 3500 to 3700

how to overclock and gain maximum battery and performance

Hi everyone... i have samsung galaxy S I9000 base rom JVP 2.3.4 and CWM recovery 3... its rooted can anyone suggest me how to gain maximum battery and phone performance ...
which is the best Overclocking app
and wat are the frequecy to be set
please advice me how to gain maximum phone performance and battery performance...
Thanks in advance

wondering the same thing.
could any one give detailed instruction?

maybe u should try a based rom (JVQ or JVR) and a kernel (like galaxian EE or semaphore ) + JVR modem

Use odexed JVR on latest galaxian kernel, there are good odex themes (I use EE SP1 clocked to 1.1ghz via tegrak. This is a minor OC but voltage at 1.1 is lower than standard 1.0 ghz!) remove all the crap bloatware (I remove loads of stuff and all samsung apps using sgs chlorine) use zeam launcher (fast, lightweight). Use setcpu for screen off profiles and also juice defender.finally, convert to ext4 then back again to rfs to clean file systems. Then calibrate battery, use noop scheduler. This will give you a very fast phone with great battery life

thanks a lot dude let me try will hope this works fine

gsw5700 thanks for the sugession ... but i am confused wen i check for this kernel .... http://forum.xda-developers.com/showthread.php?t=1196391
it says flash it if u have ODEXED JVR ROMS only!!! but my rom is JVP
please let me know how to go further and also let me know is the camera application is stock galaxy or hacked camera
thanks in advance

Flash odexed JVR, then you can flash this theme (that I use). Then flash chainfire 4.1 kernel to get root, then flash latest galaxian kernel. Use setcpu and juice defender to get good battery savings
Don't forget to hard reset/wipe after flashing jvr, tick to re partition, wipe both caches and fix permissions after flashing galaxian

thanks dude i have followed the procedure... let me check the performence

it gave me 16 hours of battery life .. and performance was stable

Why not just stay on ext4?

RFS will defragment after a while (depending in usage), I like to defrag file systems every month or so. I haven't actually tested it, but hope it will provide additional benefit. I also like to use it for a while whilst on ext4 to prove that ext4 doesn't feel any faster at all than rfs!!

I also suggest Galaxian. It's pretty neat.

So how long battery life do u guys get on undervolted galaxian?
Im on JVR w/ talon kernel OC'd to 1.2 and UV'd and i barely get 2 days of little use.

bufferpl said:

Because some kernels don't need any lagfix actived

It's not about fixing lag, that is just terribly outdated but traditional terminology.
RFS isn't slower than ext4, but the letter is still the better filesystem by it's journaling and fragmentation behavior.
In a nutshell: you don't have to convert to ext4 to have a smoother device, but you might still want to do so if you want a better file system running your device.

I get about one day of medium to heavy use and a day and a half if I don't do much. I lose about 2-3% battery over night (using juice defender)

my signature tells the setup. undervolting for the lower frequencies helps. Also check out Zach/picachu's screen state scaling and system scripts. Combine with the latest talon kernel and you are set. Tegrak aop is optional for overclock above 1200

[REQ] Froyo with some custom Kernel.. (alfs 4 example) ??

Ok, I just realized (again, and until the next time) that Froyo Pro is the best choice for me..
But I will miss custom kernel.. I tried Alfs once, and it was all right but WiFi was not working at all. Copying Wifi libs from GDX didn't help
Can someone re-make Alfs kernel to make it work on FroyoPro? (some ramdisk changes and wifi fix)
I would be grateful... and I'm sure many others..

+1
Sent from my E15i using XDA App

+1............

It could be done but kernel should be made from cm6 core.because all kernels for x8 are made from cm7(gingerbread) core.like alfs,gdx,fxp kernel,nAa...so it would be hard,because fxp gave sources only for cm7 kernel,and most of our kernels are based on fxp kernel source.

nice. ....

Its preety easy.We just need to compile kernel from se source and everything should work even on eclair.
I will try and report.

oh god im waiting for Custom Kernel on Froyo sooooooooo much
and also if im on gingerbead and for example Alfs kernel when im by clockwork install custom zip with froyo i need to change kernel to stock right?

yeap, i love froyo pro and i also love alf's kernel, especially it's OC, i get by far the best results with it, fully stable 787 mhz with smartass v2 i just wish i could combine the 2.

yes yes yes +1 for a kernel for froyo

if we compile those kernels with the same Ramdisk that we have in Stock kernel, probably it should work better in Eclair and Froyo roms, right?

flash this in cwm and you will have working alfs + wifi on froyo pro

No, you are wrong, alfs kernel works fine with froyo pro + that fix which repairs wifi. If you want, i can make video with working kernel and froyo pro

best rom for gaming

which is the best ics rom for gaming?

I think that kernel has more to do with games...
But with slimics + semaphore (xl ram) +smartass i am very happy with my gaming experience

I'm using the same config slimics 4.2 and semaphore 1.26s max mem option and smartassv2 with great results. Previously was using gamerzrom which is also a great gaming platform but is lacking on the user interface, just not smooth enough for my liking.

cm9 with sgs3 pack & semaphore 2.3.6

what about devil kernel for gaming and battery?

Elite scorpion 2 kernel have awesome 3D. It's the default kernel in Elite´s RC 1.4.1 ROM.

The 3D drivers in Elite's ROM are improved, nothing in kernel. Kernel doesn't affect gaming, they are all based on Linux kernel with some added functions and updated drivers.

gamerz rom v11 the games run smoothly ..

how the battery life in gamerzrom????

currently i have an i9000 , ICS 4.0.4 , f4kmod, with semaphore 1.2.5 VC, with bigmem, (200MB of ram FREE) and i CANT make gta 3 playable without lag...
what i can try?
what is smartassv2?

lol,,, Kernel doesn't affect gaming :laugh: :laugh:
then why the kernel developers are here?
check the Speedmod Kernel and Stock one and Semaphore Kernel on NenaMark3D

for Best result on gaming you have to disable all services on Phone.
check the background application and services, close them all via app freezers

CM9
USE CM9 HES THE MOST STABLE dont use roms with ROM control cause it sometimes get stuck

1-elite comes with neo kernel not scorpion 2 kernel
2-use slimICS with devil3_O.99 it has gpu overclock . and you can control your amount of ram
3-kernels do affect 3d gaming .

For me many Roms are good to gaming, why? because everyone do OC, use ultimate Kernell, with some perfomance changes and voltages cpu,
but specialy don´t forget some signs like heater, because when we want power and perfomance, battery will die soon, screen will be little hot, and off course cpu.

But they all have the more or less same fixes, comparing a custom kernel to stock kernel of course is senseless.

Im a big fan of CleanROM, and using untermensch OC Kernel. I've also been playing around with Ultra Fast ROM and using untermensch OC. OC went from 1.6 to 1.7, and its like putting the petal to the metal, even when its running on a modest 1.4 GHz.
Ultra Fast ROM, is a stock ROM, so it has all the bloat, but I went in with a root explorer, and uninstalled all the bloat apps.

Sir, the best rom, kernel or whatever is subjective.Try for your own and decide what suit your needs.
