[Kernel] FluffKernel Epic 4G version 1.0.5 Rom Manager Compatiable

Here the the first offical release of Fluff Kernel for the Epic 4G
Ok here are two new versions for you all.One is the performance kernel and the other is the battery saver.Both are using the new version of my initramfs that comes with ChainsDD's Superuser.apk and su binary.So i suggest if you have Superuser.apk installed to uninstall it before flashing either of these kernels since Superuser.apk will be installed in /system/app instead of /data/app.And now for the kernels.Both of these kernels are Rom Manager compatiable and have root in them.
This is the battery saving kernel.Changes to it are:
Both Kernels are updated to DI18 sourcecode.
CPU governor set to userspace you can use SetCPU to set the speed of the kernel if you like although SetCPU seems a bit unstable on anything other then conservative.
Default scheduler set to CFQ
http://www.sdx-downloads.com/devs/skeeterslint/FluffKernel-Epic-V1.0.5B.zip
This is the performance kernel.Changes to it are:
CPU governor set to performance your cpu will always be set to max this gives the best numbers in linpack and quadrant if numbers are you thing.
Default scheduler is set to CFQ.
http://www.sdx-downloads.com/devs/skeeterslint/FluffKernel-Epic-V1.0.5P.zip
This is another battery saver kernel for those who don't want to mess with SetCPU is uses the conservative CPU governor that the overclocked kernels use.
http://www.sdx-downloads.com/devs/skeeterslint/FluffKernel-Epic-V1.0.5C.zip
All kernels have been compiled against a toolchain that is stable on the newest OTA.And all kernels have been built with stock Samsung kernel source with no modifications to the source code all changes were to the .config file.
​
This zip can be flashed with ClockWorkMod or can be taken out of the zip and the zImage can put used as a replacement for the zImage in the one click root method although this kernel has root built into it.I recommend removing the JoeyKrim root method to not cuase and conflicts.
This kernel still has some Samsung bloat in it this will be stripped out as time goes on.I will also be trying out different combinations of CPU governors and schedulers to see which one performs the best.So please test it out and post your feedback.
Link to the stock samsung source that was used for these kernels.

This is not the kernel from the ota this is a custom compiled kernel it should run fine on any roms that are out right now.I am running it myself with no issues at all to speak of.

All the b usybox applets to setup the the loop device should be there. But I have never tried to use them I will have to check the kernel config to see if the kernel is setup for it.

Skeeter this its the best kernel I have used on my phone to date, however one thing to note is that the version of busy box used in this kernel is not compatible with ti backup so the busy box that comes with ti back up needs to be used.

OK it was still broken but i promise its fixed now.The battery drain probably wasn't cuased by the kernel some people have had problems with android system running away and draining battery but it has nothing to do with the kernel they have flashed back to the stock kernel and still have had issues with battery drain and android system running away on them.

I wasn't implying that the drain was caused by the kernel, I was saying that my battery was draining because JuiceDefender wasn't able to disable the APN because my root access was broken. D/l-ing update now. Thanks again!

Can i use this kernel with noobnl's Andromeda Galaxy v1.0.3 ROM?

[MOD][11/9] Underclock / Battery Tweak

UPDATE: This was causing too many lockups, moving to a minimal setup that just sets the CPU clock.
This will work with ANY kernel without perflock (nearly any kernel other than stock).
Old tweak removed, new one uploaded.
This is developed primarily for myself, please take this into consideration.
This just sets the CPU to a max of 806MHz and lowers the max clock as the battery drains, it's the collin_ph mod stripped to almost nothing.
Most of the credit goes to:

Flash in recovery.
This works great for me, I hope you like it.

Do you need to install Myn's collin_ph before this?

I was thinking of trying one of these battery life fixes but Im trying to figure out what the purpose of the userinit script they all have is for? It looks to be a pretty blatant security hole running a script off the SD card but it's likely that I'm missing something.

Regarding kernals this works on, are these with or without havs or does this not matter with your mod?

Nope, it will just overwrite it.

Thinking about giving this a try when I get home, but I'm running Toast's .35 on CM 6.1 Nightly #152. I know you said that it will work on Myn's ROM with King and Ziggy's kernels, but has anyone tested it on CM 6.1 or Toast's .35?

If you read on Kings website the changelog for BFS 11, the first line reads HAVS is out, and he went back to SVS. It will work with Kings BFS 11

Here's a question for the OP. It's been stated that JuiceDefender-like apps compliment the Colin_ph battery tweak, would the same hold true with yours or do you think there would be conflict between the tweak and said app? Thanks in advance for any help you can offer...

Yes, all holds true.
My tweak is still the Collin_ph mod at core, just my own touches to it along with some code stripped out to minimize CPU usage.

It should still have installed, seems I left some residual commands in the install script.
Because every command before that error should have run, it should still be installed.
So...until I post my new changes, just ignore the error, lol

What rom and kernel are you using with this tweak neotelos?

i9020a overclocking

Has anyone been successfull? i have tried every OC kernel and as soon as i overclock it just reboots my phone to a freeze (only way out is to either pull the battery or adb reboot). That being said the UV kernel runs fine.

Not sure if it has to do with the I9020A series.
But overall, each NS phone can tolerate its own OC levels. Some phones can tolerate only up to 1.2 GHz, some may be able to achieve 1.4GHz (or beyond). And for some of the unfortunate, some aren't able to OC at all.

Thus this post. I hope my phone is'nt the issue. it would be nice to push a little bit more out of it if i needed it down the line.

I over clocked mine to 1.4 and it was fine, I leave it at 1.0 tho, this friggin thing is quick enough for now.

hmm how do you check your radio. I'm gonna try that as a last resort. And i can set mine as 1.4 but as soon as i run a resource heavy task (n64) my phone locks up and reboot freezes.

Not sure why a radio would affect your ability to OC but...
Menu -> Settings -> About Phone -> Baseband Version
the last 3 are what you want to look at "JK8/KB1/KB3"
List all the kernels you've tried. The best in my opinion is Netarchy's 1.3.0.3-CFS kernel using SetCPU
Try intervals of 1.2 GHz too. My phone can only go up to 1.2 GHz

Yeah actually i had tried all of the bfs kernels. I just succeeded in getting Netarchy's 1.3.0.3-CFS kernel. And i can run up to 1.4 . Maybe the brain fk scheduler does not play nice with 9020a's

i flashed the BFS first, and lost my boot animation. Then i switched to the CFS, and the boot animation still didnt appear.
Any ideas as to how i can get it back?
Also, is there anyway to recover the stock kernel? I'd like to have it handy to be able to go back to it.

Wipe dalvik and cache. Flash a rom that flashes stock. Like cm7 but netarchys is so much better than stock
You can also get ogdobbers which is stock + ext4 + voodoo.

Hey everyone,
This is an off topic question but does anyone know what happened to the 1.6 OC support for Netarchy? I loved to see the absurdly high quadrant scores and instantaneous screen transitions.
Thanks,

you're better off asking that in the netarchy kernel thread in dev forums.
netarchy could answer that... not a lot of phones can tolerate 1.6 GHz Oc

[Kernel][KG2]Bali Tweaks + OC! 1.28Ghz

I added kernel tweaks from raspdeep's I9000 OC and got our bali kernel to OC, I'm running at 1.2 Ghz right now. I haven't tested this in terms of battery life, but there's a good chance your battery life may be less. So use with caution.
This 1.2 Ghz OC feels smoother and faster than stock, and better and more stable than 1.28Ghz. If you tried the 1.28 and gave up, try this 1.2, it's much better. I removed the link to the 1.28Ghz kernel because it was causing too many problems for everyone, and actually being slower due to freezing and overheating.
Battery life and stability not guaranteed
Use setcpu to control your cpu speed.
Credits to Dr. Honk for bali original, and raspdeep for OC source.
THIS IS FOR KG2 ONLY!
I have flashed this both on stock and on a custom KG2 rom, they both worked.
link removed because it was unstable - 1.28Ghz
Updated 1.2 KERNEL: http://www.multiupload.com/3QPMQY476F
3:55PM 8/3/2011
I provide no guarantees that this will work, make a backup before you try this!
This was really only made for all the kids who kept asking for an OC kernel.
It has been suggested that the 1.2Ghz kernel may be more stable, so I would suggest trying that one instead of the 1.28Ghz kernel

Flashing right now . You beat me too it ;p

Remember once you add UV to check the voltage . Just a reminder & The kernel flash's but it auto-reboot's & then stay's stuck on SK4G splash screen .

Nice work here. Just what we needed. I have one request(which if you know me you know I hardly ever make them). Any way in a future release you might be able to get Badass as a governor and sio as a scheduler? I find that combo works incredibly well an another phone of mine and would love to see how it treats the 4g. Also what are you using to set UV if System Tuner ain't sticking? I really hate Set CPU so I'm hoping for another recomendation. Thanks for this.

Let me look into finding and understanding the Badass governor, as well as the schedulers. I try to be conservative and only put things in that I understand, rather than just throwing in the kitchen sink. I agree that both governors and schedulers can impact both user experience as well as battery life.
OK, I found a better source of badass from showp1984 / "Bricked"
On the UV table, I need to work through how Linux deals with what I am used to knowing as sysctl as well as what the various apps expect.

Is it possible to backup the kernel before flashing yours? I tried to use the SGS Kernel Flasher from the market place but it isn't compatible with TWRP. Or is it recommended/manditory that I completely reflash the OS, then flash the kernel, then just restore apps using Titanium Backup Pro? Still getting the hang of it... I just have it burnt in my memory not to restore a backup over a different kernel... thanks to bhundven

Do a nandroid prior to flashing so if something breaks you can revert.

TWRP will backup your kernel. You will also need a backup of /system/lib/modules/bcm4329.ko Using TWRP to backup /system will cover you there.
I flash more kernels every day than I want to admit. The kernel is in a different partition than the system or data, so the chance of corruption of your "ROM" is pretty small. The only file changed in /system should be the bcm4329.ko (WiFi/Bluetooth module).

flashed this kernel couple days ago, its good.
but......sad to say 4 me, i dont see any difference in battery life (running cm9, kernel it came with lasted about 16hours with wifi on and only txting), with this kernel my phones battery life only last about 8-10hours (thats with and without wifi on), trying my phone on 200/1400 and at 55% (unplugged it about 7 1/2hours ago), but my wifi has not been on. (i also saw a very bad drop rate, lost 17% battery life in about hour 1/2(wifi was off and it was just sitting)not sure if its because its set at 200/1400 or something else, and i have no other apps running in the background), im not to worried about it since im trying to buy a new phone soon, so for now im trying to make the best i can out of this phone.

Glad to hear it is solid for you!
Have you tried switching to the smartassv2 governor? It is not set as default when the kernel boots (you want a robust kernel when you have to boot into recovery).
