[KERNEL] JAC XMOD OC/UV w/Voodoo and w/Colorfix [CFQ] CWM/Stock/ODIN V1.1 10/02/10

First off a big THANKS to Supercurio for Voodoo. These kernels supports/system/etc/init.d as all my kernels but there is no "pre-flash" needed in this case. Just flash the kernel and your good.
These kernels have been tested by many users for stability. You literally can't optimize a kernel during the compile process anymore than has been done on this kernel, optimized CT-NG 1.8.0 toolchain for the Hummingbird CPU and also optimizations during compilation. Almost every user has reported a notable battery life increase some users report amazing battery life compared to the stock Kernel.
~Version 1.1
~Updated OC/UV settings for even better battery life
~More VM tweaks
~S3 bug fixed
~More up/down threshold changes throughout CPU governers
~Tested multiple toolchain and make optimization options unfortunatly the difference in performance between them is very small. Stuck with previous setup.
~Based on the 09/06/10 Samsung Source Drop
" No Super secret lagfix because those don't exist"
~Amazing battery life through optimized UV/CPU tables
~More agressice up/down thresholds throughout CPU governers
~ Extreme OC/UV throughout the entire range but especially the freq's the Hummingbird processor uses the most based on the CPU tables for maximum battery life with a small voltage boost at 1.2 for stablity across more people's CPU's
~Modified CFQ governer is the "default"
~100Mhz, 200Mhz, 400Mhz, 600Mhz, 800Mhz, 1Ghz (OC) 1.2Ghz freq steps (Thanks Ivanmmj/Unhelpful)
~CPU tables optimized for "instant" clock up
~Bug fixes in perf tables (thanks Unhelpful)
~Kernel bulid optimized for cortex-a8/NEON using Level 3 optimizations.
~VFP3 and NEON support..this is available in stock kernels folks (but optimization for NEON is not )
~All stock CPU gov options available
~These are are included in the stock kernel anyways (Performance, Powersave, Conservative, Ondemand, Userspace)
~Interactive CPU gov still has bugs at 100Mhz so it was left out for an experimental branch and stability reasons
~VM tweaks
~CPU sampling rate adjustments for additional performance
~Allow small data to be kept longer in dirty pages
~Reduce volume of data written when write cache is flushed
~Anticipatory, CFQ and Deadline scheduler support (no-op removed due to high latency compared to the other schedulers)
~compiled with Cortex-A8 optimized CT-NG toolchain GCC 4.3.4​
NOTE:For compatibility with all phones this does not automatically OC to 1.2Ghz per Unhelpfuls idea as not everyone can handle 1.2Ghz. Use a user script in the init.d folder with
Code:
#!/system/bin/sh
echo 1200000 >/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
or setCPU to OC the Kernel to 1.2Ghz. 9.8MFLOPS is about what these CPU's average in Linpack at this speed. I've had it in the 10's and that may be coming back as another option.
Download the Overclock script here and make sure you put it in the /system/etc/init.d folder (right click and save with no extension for Windows users)
There are are few options to choose from: Regular Kernels with and w/out Colorfix and Voodoo Kernels with and w/out Colorfix
NOTE:Remember to rename Stock recovery updates to "update.zip" in order to flash through stock recovery
Regular Kernels with and w/out Colorfix
NOTE:For now V1.1 does not have a colorfix option due to some time constraints/Computer issues. I will get it posted as soon as I can.

Thanks to Supercurio, Unhelpful, Ivanmmj, Eugene373, and the entire XDA community. Let's keep the positive progress moving.

To be clear, when you say there's no need to "pre-flash"...
You mean init.d doesn't have to be flashed separately / first now, right?
I imagine EXT4 and Voodoo support are there too even though it's not listed?

Ready to Test.
Is this Kernel compatible with eugene373's(ROM) Frankin-Twiz ?
Any recommendations in the setcpu settings to get the maximun battery benefit ?
Thank you in advanced.

Can I flash this over Franki twiz? I have King's kernel currently with the Ftwiz...but I'd much rather work with JAC.

Exactly no init.d flash needed.
EXT4 support is of course there but Voodoo support is being worked on for beta5 ATM to bring 100% support/stability to T-mobile Android users.
This is something for people who want amazing battery life while waiting for a Voodoo based version of this optimized kernel. Or for those that just don't want to use Voodoo and just an optimized Kernel. (and I mean optimized...toolchain optimized for the CPU and CFLAG Level 3 optimizations as well..you cant "optimize" a kernel any more than this has been.

This should be fully compatible with FrankinWiz.

Downloading now.So JAC, do you think this has the ability to replace VooDoo?

My question is will this work with Vibrant firmware T-959UVJI2 since you stated this?

My 2 cents...why would it replace Voodoo? It's not a lag fix in and of itself. I asked earlier if it includes Voodoo but even if that's the case, I wouldn't consider it a replacement but rather a complement.
OT: Like your sig. However, I think Chicago's size might have actually something to do with it.

No Samsung still has not released the code for that update. I and a bunch of other users on the forum have sent emails to Samsung to release the code so we can provide you with custom Kernel's for the newer software leaks

Correct this is not a replacement for Project Voodoo. This is more of a compliment like the user said above which may be combined with Voodoo beta5 once it is ready for Prime time.

Long time no see defconoi! There is already another version being blind tested with BFQ vs the optimized CFQ setup to see which one comes out one top.
Google apparently did the same thing for Froyo and decided that users experience with BFQ was not superior to CFQ according to user feedback. So I'm trying the same thing myself

Thanks Guys. That was basically what i was trying to get at.
Jac installed now. Seems super snappy. Im gonna rock it for a few hours and post results. As of right now my battery is sitting at 72. Im going to turn off 3g and see how well it saves battery life. I use overclock widget to set clock speeds with an option of underclocking while screen is off from 400 to 100.

Haha, "no super secret lagfix" made me laugh. I just mentioned that on King's thread about his "Super King Lag fix"

I agree 100%, I try not to involve myself in the bashing, but his changelogs really are meaningless, and can be very misleading. All it does is confuse people and cause flame wars, especially when hot button topics like "lag fix" are used. Thanks for your hard work, and for keeping things legitimate & honest. You're the man!

so far so good! 9.85-9.9mflop nice and responsive.

Which kernel is better: speedmod or voodoo?

hey guys,
im using the voodoo kernel at the moment but i want to know whether the speedmod kernel is better.
what's the difference between those two ones? which is more reliable? which is the faster one?and which has a better battery life?
my second question is wheter a lagfix is still needed for the kernel. i heard the lagfix needs more battery.
ty in advice

Its a matter of personal preference.. You should try both kernels and conclude for yourselve..

but can you say something in general? there should be some differences...
ty

i'm using Stock JS3 with voodoo 5.2 and there is zero lag, and battery life is fantastic (after removing most of the samsung bloatware).
I really don't see any need for any of the extra 'fixes' the other kernals add

You can read the differences on both kernel's pages.
Which is better: apples or bananas? It's all based on opinion. Flash one, if you don't like it, flash the other.

I prefer voodoo,
At the moment im using the advanced kernel v666.2, and its bloody awesome.
Supercurio says voodoo doesnt increase battery life, so rock on!
Speedmod, whilst good as never been as smooth for me, even 500hz versions.

I think either kernal is good. Have used both and not much difference between the 2. My personal opinion- speedmod feels a little smoother than voodoo. Was using voodoo for a couple of months but now on speedmod.

One difference is voodoo is compiled by supercurio and the other by hardcore.
Sent from my GT-I9000 using XDA App

ty guys. i think i will stick to voodoo. actually i have the 5.2 version istalled on my gt-i9000.
but is there a thread in this forum where i can check for the latest voodoo kernel? i didn't find it...

5.2 is the latest version.. You should check project-voodoo.org for updates or folkow his voodoo sound thread

ty a lot. now i'm fine

Seems to me voodoo is bit smoother and speedmod has maybe better battery life.

You should get CWM Recovery and try for yourself since it's so easy to switch, I am on Darky's Ron and currently using Voodoo. But I was on Speedmod before 9.1 and I can't find any difference in their smoothness. The batterylife is more depending on your Rom and settings.
Happy flashing
Sent from my GT-I9000 powered by Darky!

I switched rom and kernel at the same time. So I can't fairly compare both kernels.
I appreciate Speedmod's kernel because it has tun support for Openvpn.

for me, I use speedmod as it has better battery life

I use SpeedMod, for the performance tweaks. I did briefly use supercurio's kernel, but then switched over to hardcore's, chiefly because of how it was geared at performance and efficiency, or so it said, anyway.
To the extent of my limited knowledge, I can summarise their technical advantages as follows:
Advantages of SpeedMod
Various optional performance boosts - promises battery and speed improvements, but I haven't actually done any tests for proof
Customisable lagfix - can choose from different file systems (ext2, ext3, ext4, ext4nj, rfs, jfs) and where to apply them (data, system, etc)
Advantages of Voodoo
Simplicity - lagfix (and other tweaks) automatically apply on boot, no need to ever go into recovery mode
Both have colour and sound tweaks (SpeedMod uses Voodoo Sound), and generally are very stable. You might also find less of a need to update

You don't say...

I guess voodoo is much better. I haveused both of them but speedmod has a lot of problem like screen brightness which will never be fixed! althou hardcore claims to have done so. about the battery consumption you can not say which of them is better cuz it depends on your rom. on Darky voodoo saves more and speedmod drains ur battery. that is why Darky switched to voodoo in his latest roms and if you install darky rom configurator you will see that voodoo is recommended.

I prefer the speedmod kernel because you have the choice in regards to optimizations and lagfixes. The latest kernel (k12u) really speeds up my gps fixes!!!
Stock XXPY + JPA WiFi driver, rooted, speedmod k12u 500hz
Speemod kernels are being updated almost daily,so the easiest way is to get used to using cwm recovery!

Your experience with Superoptimized Kernel

Hello everybody!
I'm running on my GT-I9000 the speedmod kernel K13A with lagfix enabled. Therefore my GS doesn't work so fast. Then I read about superoptimized kernel which promises huge performance.
My question is: If you tried it what do you think? Is it better than Speedmod or Voodoo Kernel?
And what about Speedmod Kernel BIGMEM?
Thank You very much in advance!

I tried speedmod, super optimized and voodoo kernel.
I love the darker brightness level of speedmod as it saves a lot of battery.
VSF in super optimized kernel is a good idea, but it switches all the time, what made me nervous.
voodoo is ok but does not have the darker brightness level.
So i am now on speedmod kernel as the best "allrounder" stable fast enough and good battery life

Early Gingerbread kernel selection. What kernel to choose dillema. Available options.

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)
Click to expand...
Click to collapse
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
Sent from my GT-I9000 using XDA Premium App

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

Anybody wrote opinion about CF-Root 2.6 , please ?

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?

[Q] Which kernel

Hello,
I would like to flash a custom kernel to my SGS which is running CM9 nightly.
I had CF-Root kernel and semaphore when my phone was running GB.
Now i have ICS on it and i want to oc it so i need a custom kernel.
Which is the best? Semaphore was very good when i was using GB
Because it has so much tweaks and other things.
So i maybe install Semaphore or should i try other kernels?

use semaphore. its stable. keep it as backup and try other kernels. when and if they go Kaput or bootloops go back to semaphore. performance max is for devil. but in my case it proved unstable after a while. that's just me thou.

I tried semaphore 1.2.5 but it goes to bootloop

Bootloops are often caused by not clearing/wiping cache(s) from recovery console after flashing.

Semaphore 1.2.6 is latest one. To try that. Also clear cache, dalvik cache, init.d and ns tools.

1. you have midnight kernel for ics - very stable and save your battery power/
2. devil 3 - very fast kernel for gamer's . very good with OC.

SEMAPHORE

Semaphore is the be(a)st in my opinion

Devil all the way! So many options. My phone is totally dialed for performance. And never crashes. Ever. I love it.

It depends wether you want to spend your days forever tweaking or you want out of the box no problems.... for the latter use semaphore

You'll find that most of the kernels are based on the CM9 kernel (by pawtip) and simply add extra features, or default settings. Semaphore is a good mix between 'flash and go' and tinkering, so whether you want to just leave it as default or OC, UV etc you can

What the **** ? Devil3 of course bro ! Test it, you wont change the kernel ever !!!

On CM9 first i used MNICS (midnight) without any problems. Then i switched to Semaphore but experienced a lot of problems with several versions. So i switched back to MNICS, perfect battery and fast but not a lot of tweaking.
Now i'm on Tiramislim v2 with the devil kernel and its superfast and good tweakable. Has a lot of governors and a lot of settings, all you can wish for!

Dude, you should use DEVIL
in my opinion, devil is the best kernel for ics!!
semaphore is fine, but a lot of features are missing..(such as blink status, "cpu governor"- there are 4 governor only.. in devil and other kernels for ICS u can find over 10..) and a lot of other stuff are missing.. semaphore has poor features and for me, devil was even faster and better than semaphore..
I used both of them- semaphore first for 2 weeks and after that switched to devil and ive been using it like 1month so far..
)and few days ago I switched for semaphore in my brother's phone.. after 1 hour changed it to devil 2 like mine.. really tons of things are missing..)
in conclusion:
devil is the best! stable+ fast+ deep sleep+ includes tons of features and great OC (thats what u want..)
semaphore- fine, but a lot of features and options are missing, not high OC, no blink and WAY MORE..
(&devil is faster) both of the kernels are battery friendly.
