Main reason for most kernel devs to reduce kernel size by decompression is that the system partition (in which the kernel has to be placed) is no so big.
Some kernel devs have already reached the size limit with adding many modules, libs and add-ons, that on some phone's the kernel can't be flashed any more.
I think that e.g. gokhanmoral has come to this situation with a special version of his ICS SiyahKernel ... maybe you should have a look at his changelog.

[KERNEL][BETA] RAGEmod v1-T30

---NEW KERNEL THREAD---
This kernel is based on Hardcore's SpeedMod K1-T30 Kernel
Why another kernel?? Because I can, I like the challenge and I can probably do it as well as any other?
Features:
support for SetCPU OC (upto 1400MHz)
UV between 800mV and 1400mV
support for Boot Animation
support for BLN
SpeedMod K1-T30 initramfs + boot animation
SpeedMod K1-T30 kernel source patches
Samsung Update 2 Applied (as per K1-T30
CIFS working
Charging touch sensitivity fix.
The goal of this kernel is to take the battery savings gained from HardCORE's kernel and allow undervolting and underclocking to further improve battery life. I added Boot Animation and BLN support just because I could.
As usual, this kernel could break your hardware, so only flash if you are not concerned with bricking your device.
That said, I have flashed this kernel on my device and it still works.
Thanks also to the authors of Ninphetamine kernel - their SetCPU supporting code was the basis for the SetCPU support in this kernel, I have also used BLN code from their Git Repository, thanks to creams.
Change Log:
v1-T26 - public release based on SpeedMod K1-T26
Added BLN support
Added SetCPU support
Added UV support
Added bootanimation support
v1-T27 - updated base to SpeedMod K1-T27
v2-T27 - updated base to Samsung Update 2
Same feature set as previous versions
CIFS working
Closest match to SpeedMod K1-T27 but with Samsung Update 2 sources
Touch sensitivity fix from ninphetamine.
v1-T30 - updated base to SpeedMod K1-T30
Same feature set as previous versions
Future plans:
Keep up with SpeedMod current releases as they happen and source patches are released.
NOTE FOR ALL:
Patch files are for developers, not end users.
Source patches attached for developers - apply against Samsung Update1 sources.
Source patch for v2-T27 and newer to be applied against Samsung Update2 sources.
Gonna try this for sure , always loved Hardcore kernel, back in the Gti9000 times, but i think that OC/UV is something missing in his kernel. I'll report when i'll have tried it out ^^. Thanks !
nice.. waiting for you to update to t26..then will give it a go

Typical Victorian!!! Oblivious to the rest of the world.
Good to see many Kernel developers coming on board
May be its time to disclose the sources and GPL as other KERNEL threads being locked for want of it.
Other developers whose initial thoughts/ideas was reused will benifit everyone if what you have achieved over and above will make the original Kernel even more robust

Great work !!
Just tried it and No problem so far.
Wait for your next update, based on Hardcore's SpeedMod T26
cheers
Works great for me, too!
Just as already mentioned above haptic feedback isn't working, but I don't use that anyway.
I guess this kernel is in the wrong section. Although I do admit that this requires far more skills winzipping a rom together, this is basically a matchup of ninphetamine and speedmod, and therefore has nothing to do with original rom development.
Well, it's not a cut and paste coding job if that's what you're implying, I studied the required code from Niphetamine and implemented it (but reduced speed limits and subsequently speed steps) in the source for SpeedMod.
IMPORTANT: all vibration not working in first beta. Will fix and repost. Sorry, but it is a beta!
Sent from my GT-I9100 using XDA App
If you can please mod the T26 to add these futures: Bootanimation,BLN, OC and UV. Very ngood to see more and more kernel options available. Thanks for your work man

Can't code for toffee, wondering how difficult it is to alter said limits/steps and put them in another source?
Genuinely curious - doesn't sound tough, I stand to be corrected and/or educated.

[Kernel] [ICS] VDS kernel v2.0

Hello guys. Those of you, who have been monitoring ray's dev section, know, that there is such a kernel for GB, as "pure emerald' or "aire's" kernel. But its problem is that it's for GB So i decided to do this kernel for ICS. I'm from russia and 4pda, and on our forum we don't like many "svistoperdelkas", which means that we don't like to have many useless (and sometimes not stable) features.
So, you can understand now, why there are no many features in my kernel which you can find in sirkay's kernel, for example. The advantage of such a kernel is that there is no any trash in it, only main things.
Features:
Clean ramdisk
Removed Fota
ext2, ext3, ext4, vfat, ntfs support
USB OTG support
Init.d support
Linaro
DooMKernel recovery (it's the best, IMHO)
Added smartass2 governor (a very battery friendly one)
Swap, ZRam
2way call recording (uses CallRecoder by skvalex)
And now smth really new (for my kernel at least). Now YOU choose what OC to use. I've got 3 versions of this kernel.
1) 1.4 OC + uv (very battery friendly)
2) 1.4 OC no uv (for those ones, where uv causes random reboots) (not so battery friendly)
3) 1.6 OC + vdd. (not battery friendly at all, only for performance)
Download - link
One more thing. You can either believe it or not. But still. My HDD is dying. First 4GB of it are already covered with bad blocks. Also, the 10th GB is "bad". These bad blocks are "hardware". My linux is installed somewhere at 40th gb, but i think it won't take very long untill it's dead too. The first version of my kernel was downloaded for 260 times. Not so much as on 4pda (2000+ ), but still quite a lot. If every person who have downloaded it donated 1$ for me - i could buy a new HDD. So, if you are not indifferent to me and my HDD, please, donate to me thanks in advance
Wow!!! Finally a new kernel!
I hope it's battery friendly :laugh:
Aire kernel was my favourite GB kernel
Best regards
:good:Tnx,this is just what i needed....flashed&testing...
:good:
P.s.: I don't like "svistoperdelkas" too...
flashed, i'm trying it :good:

im not mad, just my curiosity to know how do you define "trash". if that so, then me too dont like "svistoperdelkas". i always made 2 version, one for users (with features they've requested) and one for me (with only smartassv2 and intellidemand gov, freq max 806mhz, dont UV, didnt use zram, disabled debugging, disabled unused modules).

[4.0][ROM][KERNEL]Linrom V2 (ICS, Compiled with the Linaro Toolchain!)

First of all, a couple of disclaimers. This rom is based off of my dev team's repo, and I have merely patched it, and added linaro/general optimizations. I am not responsible for ANY damage caused to your device from these roms, including, but not limited to, bricking, general malfunctions, and cthulhu rising from the dead.
Note that support is limited. I have a lot of projects I am working on, or considering working on, and actually have a life outside of development . I will be able to help you resolve issues, provide new roms, and patch/improve older ones, but not at quite the rapid pace you might want.
That said, let's dive into the part that really matters!
I started playing around with the Linaro toolchain a few weeks ago, hearing about how amazing it's benefits are, and seeing the performance boost firsthand in my N7. I managed to get TeamSuperNova's rom to compile with linaro successfully (after a few days of patching), and the performance increase was incredible!
(UN)Official testing: Not garenteed to have 100% accurate results, but a rough comparison.
Dead Trigger:
GB: Unplayable
Nebula: Only playable on low
LinICS: Playable on high!
GTA III:
GB: Completely unplayable
Nebula: Playable with EVERYTHING disabled
LinICS: Playable with resolution/draw at 100%!
UI:
GB: Laggy/frequent redraws
Nebula: No redraws/low UI FPS
LinICS: NO redraws, the entire UI is as smooth as butter.
Quadrant: 2163
Vellamo: 1006
Browsermark: 1800-ish
I am completely open to accepting a partner in this endeavor (as I do not have time to adequately support it), so please pop me a PM if you're interested. Of course, you need to know how to compile with the Linaro toolchain, and have at least a rudimentary knowledge of C (for fixing compile errors).
More to come in this thread as I complete it!
ROM Downloads:
LinICS (fixed) V1
http://www.mediafire.com/download.php?hlidwxqwyfh4918 (now compiled with the latest linaro toolchain, and comes with a linaro-optimized kernel with -o2 performance tweaks!)
LinICS V2:
OMX package FIXED (enable video playback, flash in CWM, thnks to zaclimon)
LinICS V2 Download
Changelog:
Kernel-
-Added modded kernel config for extra performance
-added more linaro optimizations
-1.5 GHZ O/C!
-Miscellaneous fixes and optimizations
ROM-
-Added FULL -o3 optimizations
NOTE: All these roms come with a linaro-optimized kernel as well, which provides a nice speed boost!
DONATIONS:
Donations are greatly appreciated as always, but never required for continued development, although they do serve as a nice incentive to continue rapid development, and as a nice vote of confidence. A few dollars go a long way!

At the moment yes, but I am compiling one with a newer toolchain which should provide a decent performance boost over the last one, and some stability improvements. The Linaro kernel is also in the works, and may be out as soon as tomorrow.
Thanks for the share.. works great.
Can you do a quadrant test too, so we can see how much the performance has increased

Quadrant doesn't really showcase the performance benefits of linaro, in my personal opinion. Linaro does improve benchmark scores, yes, but ultimately it most improves the usability of the UI, and removes the lagginess that plagues our devices.
A few fortunate updates for you guys. Firstly, I have a fully working Linaro kernel ready to be rolled out . Turns out, my touchscreen issues stemmed from the touchscreen driver somehow not getting included in the ROM (found this out after comparing zips). Derp. It now works 100%, and FLIES. I thought that ROM I had before was fast, but this leaves it in the DUST.
New zip coming out tonight, that includes the linaro-optomized kernel, and a new rom, compiled with the latest linaro toolchain (nice performance improvement). Believe me, this is something to get excited over, as I have never seen our device this fast before, ever.
EDIT: just ran linaro. Hitting framecap on most of the 3d benchmarks easily, and scored 2410, which is extremely impressive for a single-core device, and statistically hits in the range of Tegra 2 devices, such as the Transformer. New zip up in a few minutes!
EIDIT: Link up! PLease tell me what kind of a difference you feel over TSM (TeamSuperNOva) ICS!
So I install this with the exact same steps as zaclimons but flash your zip and kernel instead? Can I flash this over zaclimons or should i revert to stock before flashing?

Yes, you can flash it over, but have another ICS kernel ready if you flash. I just figure out that touchscreen is NOT working at the moment, and i'm trying to compile a kernel with the latest toolchain that has it working.

I would be happy to work on that later this week, as soon as I can get the linaro kernel work in (touchscreen modules doesn't even insmod anymore).
@theraf, I will be happy to do that, and I'll probably switch to it for later releases, depending on it's DL speed vs. Media fire.
@everyone, if you flash the ROM in its current condition, touchscreen won't work. If you don't t want to flash a new kernel (from TSM ICS), then plug the following commands into adb upon boot:
cp /system/lib/modules/qt602240.ko /system
su
insmod /system/qt602240.KO
The first command only has to be completed once, the other must be completed upon every boot.
I'll get a fix up soon, but this is a temporary workaround.
from my experience dev-host is faster and gives you the md5 hashes which you don't get with mediafire
Finally managed to fix the kerne! Turns out it was just a small issue in the build script we were using. As compensation for the downtime, I now have it compiled with full -2 optimizations (-o3 is being tested to see if there's any noticeable performance improvement). For those of you who aren't linaro fanboys, this adds a nice performance boost to the already speedy kernel.
For developers, I integrated the touchscreen driver into the kernel, for easier use (and, it was having trouble insmodding at boot). I'll update the source in a bit, fully prepped for Linaro, and ready to go. Check for it on my github, not SuperNova's, and I plan on adding some kernel patches over the next few days.
I have updated the zip in the OP to include the new kernel, so just flash that over your existing installation. I can personally confirm that everything is 100% working, and has a huge speed boost over stock (TSM CM9).
i suppose Camera still doesn't work?

[Kernel][Overclock][V2] Overclock kernel with boot menu for 4.4 Kitkat [Fandroid]

Thanks to XperiaSTE team for the overclock kernel source first. I just did the config and compile but nothing else.
This kernel will overclock your device to 1.15GHz. The overclocking will provide a better performance and a smoother user experience.
I'm using a kexec multiboot kernel on my device, so I didn't test the kernel packed as elf format. It should be good because I have done flashing the self-built kernels several times.
The overclock source doesn't seems to be the latest but everything works~ Maybe that's because the modules in initramfs? (I did nothing to initramfs)
It's nearly impossible for me to upload the kernel on something like devhost/mediafire, so sorry for that. Could someone upload it on these sites please?
V2 Changelog:
1) Use GCC 4.9 Linaro to compile.
2) Change the SLQB allocator to SLUB. I don't really think SLQB is stable.
3) use 2G/2G user/kernel split. It seems to have a better performance.
4) PID namespace
5) NOTE:NO recovery in V2! Instead of recovery, the kexec multiboot menu by @percy_g2 is added. Big thanks to percy_g2. For how to use it, see Link:http://forum.xda-developers.com/xperia-u/p-development/kexec-multi-boot-menu-t2647623
* To enter boot menu you should press the power key when vibrate

Thanks for your support!
by doing diff -u to the two xperiap_defconfig, the configs seem to be same.
So XperiaSTE did nothing more to the overclocked kernel.
therefore the config isn't changed and the only change is in the code.
Doing diff to the whole source tree will take much time so i didn't do it
By the github commit the changes seem to be all related to overclocking.

Just a suggestion for anyone thinking about flashing it right away:
Wait a couple of days/weeks for someone to do some testing, you could fry your motherboard (happened to me on my previous 2 phones).
I'm not saying this kernel will do that, but it's just a precaution.

How to built my own version
This kernel is wonderful. But if the among of apps grows up, the system will become slowly and stucky. I want to add zram and memory merge support for this kernel. However, I don't know what to use that source that posted on github for doing this. Apolo 7.1 seems doesn't have a kernel repository, but just a init repository? What should I do? I am new in making kernel. Thanks.
My huge thanks to the developers of this amazing Kernel. I really appreciate your work. It works perfect with NeatRom 8 ! Thank you.
Apolo Kernel Config
Hey guys I'm using KK Neatrom V8.0st with KERNEL Apolo_7.1_CM_Regular. What is the best of scheduler/governor for this rom?
Apolo voltage versions - I still don't understand
Ok, I've read OP and searched relevant replies and I still don't get what's the real difference between particular Apolo voltage versions and the difference between flashing another version and just setting corresponding voltage presets in configurator app.
So, there are CPU, GPU and "internals" voltages. In Regular and Extreme GPU and internal are set to -50mV (according to OP), so there is no difference in these. The only difference seems to be in CPU voltages - which can easily be set in app. Where is the catch?
Yesterday I also made an interesting investigation (maybe relevant to this question). I had an issue with wifi not working with Apolo/NeatRom combination. Apolo Regular worked fine but Extreme V0 didn't, other conditions being absolutely equal. I can understand that lower voltage may lead to certain parts of the SoC not working properly. But again - the internal voltages are the same in Reg and V0. (This problem was solved by clean reflash of ROM and kernel.)
Edit: OK, I now read the OP one more time and found Voltages PDF. This explains everything....

Press the button under "More information and Voltages values" heading in the OP. The whole hidden text under this button is interesting and there is also the link you need.

Thanks mate
tar file
where can i find tar file for this kernel so i can use with odin?
It works perfect with NeatRom 8 ! Thank you.:angel:
I cannot find BFQ I/O in your new kitkat version anymore , it is something wrong with it?

No improvements for me. Still ~2 sec delay.
Anyone felt the difference?
[ROM][5.0.1][I9100] CyanogenMod 12 [ALPHA][12/22]
I have an internal memory of 12 GB problem instead I only 1.89 GO
thank you
@pedestre : would you consider making cpu thermal limits editable? Also, the "ZEN" i/o is pretty decent, should you want to check it out.

Break the wifi on slimsaber
Hi, the latest beta (7.2 beta 3) installed over SlimSaber 21/12 breaks the wifi and i can turn it on. Any workaround? thanks.
7.2 beta 3 OMNI (zeitferne fix) works OK
I am on the 7.2 beta 3 OMNI version of your kernel (with zeitferne fix) since 24h now.
Everything works OK, very smooth. Not a single problem so far.
Thanks for bringing back the BFQ i/o in your 7.2 beta 3 , Keep it up!
zzmoove + BFQ = Awesome
Fix for Fuse bug in 4.x branch ?
I see that 4.X branch beta 2 does not have fuse bug included. Is it possible to add this?

Hey guys,
Is it possible to get .tar files of the latest KitKat or Lollipop versions of this wonderful kernel that are flashable via Odin? Would love to use them in order to install Lollipop on my phone.
Thanks in advance and best regards
Edit: A user from a German Android Forum (www.android-hilfe.de) was so kind to create and provide the different kernel versions as .tar files for Odin. Here goes the link. Thanks a lot to KST66!
Edit 2: Also just saw that @gsstudios provided the .tar files in the development thread. Thanks a lot to him as well!
