Is it possible to port kernals from i9100 forum to our device? They have so many different kernals and mods that we don't have and it would be nice to get them ported to our devices. Entropy has done as Fantasic job with hellraiser and it have given is the ability to port a large number of roms over in the i9100 forums. The only thing that we are missing that would complete the merge between our device and the i9100 would be kerenls. Is this possible? What are the hardware differences that would cause a problem when trying to do so? Obviously the soft keys and mapping are different but we have a fix for that. Is the processor the same? Any devs out there on our side have any feedback on this?

Mainly a few defconfig tweaks, and also possibly initramfs tweaks.
It should be a matter of taking a defconfig for an I9100 and changing the correct options via "make menuconfig" - don't remember exactly which those are.
I am not sure i know what that involves but how difficult would that be
I've had this phone for a few weeks now and I've been rooting for only 3 weeks and its the greatest mobile experience of my life. The freedom of Android and the versatility and power of rooting makes the SGS2 the all around greatest phone on the planet in my opinion. I'm currently using Unnamed 1.3.1 with Entropy's DD and this combo has been an awesome experience so far. I recently experimented with the Siyah kernel (I9100) and loved the variation of governor choices and the power that the kernel provided. I'm also a huge fan of Entropy's kernel because of the great balance of performance and battery life, however when OC to 1.4 or 1.6, the Siyah kernel provided so much more power based on bench tests. After experimenting for an hour I went back to Entropy due to the issues with the soft keys. If a port of the Siyah kernel is not coming any time soon to the AT&T i777, does anyone know of a patch or mod that can fix the issue with the soft keys when using a kernel like Siyah that's made for i9100 on our AT&T i777 ? Any help or feedback on this issue will be greatly appreciated.

There is already a patch for this included in Hellraiser package that Entropy made. There is also a patch for the home button haptic feedback.
Sorry if I sound really dumb asking these questions as I'm definitely a noob when it comes to rooting. However, isn't Hellraiser a rom for i777? So if I want to use the Siyah kernel with the soft key patch it would have to be with Hellraiser? The reason I'm asking is because I really love Unnamed so far. Its my first rom and its so smooth and efficient. Also, what if I wanted to try out a particular rom for i9100 on our phone? Same soft key issue would arise right? It seems from the OP that a possible solution also has to do with Hellraiser. If this is true I'm confused as I thought Hellraiser is a particular rom for i777. Please elaborate.

Hellraiser is a porting tool to take ROMs from I9100 to I777. Among other things, it replaces the kernel.
To get the touchkeys to work right when trying to compile an I9100 kernel for I777, at the very least you need to set "Target Locale" to NAGSM in the System Type menu within "make menuconfig"
You will also need to set CONFIG_MAX8922_CHARGER in the defconfig. I forget where in "make menuconfig" this is buried
You will also have to choose an appropriate initramfs - the one that comes with the kernel you're porting may work. Also, the approach various devs use for pulling in the initramfs differs from kernel to kernel. Many devs don't even provide their initramfs in their source repos (good luck pulling a clean one from SiyahKernel... LZMA/XZ compression makes this nearly impossible.)
Thanks for the insight Entropy but I'm way too raw in rooting to grasp some of the stuff you are trying to explain. Also I want to say thank you for the awesome work on your daily driver kernel (which i'm happily still using). In regards to Hellraiser, what do you mean by "replacing the kernel"? Do you mean that Hellraiser will allow i777 users to use i9100 roms with a compatible kernel of their choice? Finally, what are the chances of some developers porting a i9100 kernel over to i777 like Siyah? Based on your previous post, it shouldn't take too long right? I believe this would breathe extended life and possibilities into the i777.

What I mean is that Hellraiser takes the kernel from an I9100 ROM and replaces it with an I777 kernel (right now, mine.)
Someone can try porting a kernel if they want, but I have ZERO interest in putting any effort into porting Siyah. Judging by all the problems people are constantly having, half the features are broken. Also, gokhanmoral does not respect the GPL and publish source for his betas, so it's impossible to separate one change from another.
Thanks for the explanation Entropy512. I was able to get in touch with Gokhanmoral and i'm currently testing out a Siyah port for i777 for him now. Regardless of which kernel i'm using with Unnamed rom now, I can not thank you enough for all of the hard work that you've put into your DD kernel. It will always be one of my main kernels. I can not say enough great things about it. I'm just experimenting right now to see if I can get some more power out of this phone at similar frequencies and this is where the Siyah kernel comes into play.

any thoughts? just rooted it yesterday, was trying to figure out what the best kernel is
Stock, lol. Whatever comes on the ROM is going to be your best bet right now.
I am using stock rooted with ziggy kernel due to his having call recording enabled. Works well for me.

I used Ziggy's for a few weeks but like most other users I found that it rebooted itself at least once a day no matter what the clock settings where (innefabilis ROM).
I switched to the OC dsb kernel & it has run absolutely perfectly ever since, but I don't see any huge advantage over just running the stock kernel at this point.

It depends on what ROM you're running to some extent. Also, people are having different experiences running the same ROM/kernel combo so ymmv.
I would decide on a ROM you want to try then read through that ROM's thread and look for issues people are having and what kernels they're using. Then read through the kernel threads and check for issues for it being used with the ROM you like.
It will depend on how you use your phone too. I've read where people running Ineffabilis ROM with ziggy's kernel are fine except if they let the phone charge to 100% while it's on it starts bootlooping. So I could never use that since I usually charge overnight and need to use the phone as my alarm clock. I went with dsb but haven't done any oc/uv tweaking yet.
You can always try one out and then change it if it's not working out for you.
I've personally used ziggy and dsb, I didn't notice much of a difference between either, but dsb was/is SUPER easy to flash, puts boot.img INS ph91img.zip on your sd and reboots to villager for easy install (ziggy might have done this to, I don't remember)
I also used both with inefabliss and didn't notice any issue with ziggy, but results may very!

Sorry if this has been discussed but I can't find it.
I've just installed the latest CM nightly build (7.2.0-RC0 Jan.12.2012)
The kernel included is '[email protected] #1'.
Which kernel is this and is it good to leave it as is, or can I install a better/more compatible kernel over the CM build?
the siyah kernel looks promising, is this a good combo?
Thanks!

Kernel is a completely personal thing. No two people have the same usage patterns, etc of their phones. Flash it yourself, decide for yourself. Siyah DOES have a lot of features. But it is up to you to use them. Hypothetically, if you flash the kernel, then don't actually USE any of those features, then was there really a point?
even though i dont use most of the features siyah has, i seem to get better battery life with it. maybe that's worth considering even if you dont need overclocking/undervolting and such things

If you don't over clock/under volt, and are only interested in battery life, then try SpeedMod.

Thanks for the replies,
I am especially looking for battery life. SpeedMod looks great, but isn't compatible with CM or MUIU unfortunately.
I'll just stick with what I have for now, then may try siyah if I find the battery drains quickly
Cheers!

Sorry, I totally missed that you're on CM. Yeah, SpeedMod won't work. My bad.

Hi All,
I'm looking for a stock TouchWiz (TW) Kernel for JB 4.1.2.
No OC, no BLN, just a stock kernel.
I know they are included in several roms, but i'm trying to add it to a rom that doesn't offer a stock kernel version. I found one that was close, but for whatever reason it removed vibration control.
The OC versions (with and without) both remove the function of my capacative buttons.
So my question is... Does anyone have a stock TW 4.1.2, non OC kernel or if not, would a dev be so kind as to rip it and make one available?
Thanks so much for your assistance.

the only thing I can think of which may come close, but I don't know cause you didn't say what ROM you are running and they need to be compatible, might be a KERNEL from BLOWNFUZE. it is 4.1.2 made for BIGFAU and his BLACK JELLY. I was trying to compare what it has and what you dont want. maybe you should look for yourself, you can find it on p.115 of AOKP ROM thread.
might be as close as you can get without finding some one to tear their work apart for a single request. PHASE KERNEL would be the only other I know of, but it has OC/UV.
unless there is something I don't know about, which IS possible as unfortunately I dont know everything.
good luck
whatever you try, make a back up first buddy

The rom I'm running is [ROM][4.1.2][Padawan-Kang] Prophylactic 1.0 but my intention was just to have the kernel as a standalone option for those that just want the stock kernel.
The problem I'm having with the OC kernels (Fuze and Da_G) is that the capacitive lights are not working with them. Fuze's works for for BLN, but i'm not using BLN. Functionally, both of those kernels are super fast and I have no issues with stability or performance.
For now, I'm ok with living without it as it's a nice to have and not a need so I respect your opinion in being the only one to request such a kernel. My sole thought was just to have it as an option for those that don't need/want OC and are fine with stock functionality for the kernel.
I didn't think AOKP kernels could be used with TW roms, am I mistaken in that?

that is true, but as I said and as BLOWNFUZE states in his post, he designed it for BIGFAU and his ROM. its sounds and looks as if ANTHONY has provided an option too. his is the PHASE KERNEL though isn't it ? that's why I went back and edited my original for you to make back up, whatever you do.
let us know what you try and if it works, others may be curious.

Yeah, I realized the BlownFuze was meant for BlackJelly and it works just fine with the ROM I'm using. The [ROM][4.1.2][Padawan-Kang] Prophylactic 1.0 uses the Da_G version 4 which has a slow charge issue, that's why I reverted to v3 which doesn't have the slow charge issue. Da_G is working on that, but even with that Kernel the capacitive buttons don't light up so in that regard, they are both great kernels that OC, and are stable, but don't enable the capacitve so they're in the same boat for me.
The phase kernel I need to try again to verify that the capacitive buttons don't light up, but if memory serves, it only works fluidly with smartass V2 as the governor. Again though, with the capactive issue, it's in the boat with the other OC roms.
Those were the only Kernels (one exception that I'll note in response to the next post) for 4.1.2 TW that I was able to locate which lead me to the post. I certainly have headed your advice regarding a backup and I have 2 just in case .
As I said, it's a nice to have, not a requirement. I'll update this if anything changes.

Yeah, I tried that one as Anthony linked it in the thread, but it removed vibration for me and I ended up missing several notifications during work hours because of it.
Otherwise, it worked just fine in terms of capacitive buttons lighting up. You're welcome to try it and confirm my findings.

****EDIT**** Confirmed that it's not a kernel issue.
Thanks for this info, I suppose I didn't think about it being a ROM issue that would impact the lights. I have double and triple checked that setting toggeled it off/on and tried each one of the options with each kernel.
I guess I just assumed it was the kernel.
Any idea what in the ROM controls that? I'll reply in the original thread to see if we can figure that out.
Thanks very much for confirmation that it's not the phase kernel that' causing the touch key lights issue.

Hello,
I couldn't find anything too specific on this so I thought I'd ask here.
I understand the nature of a kernel, and how it regulates the way in which applications interact with the hardware of the device. I also understand that some kernels may offer more features than others.
I was installing BeansTown's Rom for the S4, and when prompted to install a kernel, I realized that I honestly had no idea which one would work best for me. I have 3 options with this ROM - Stock Beans Kernel, Faux Mainline Kernel and KT Kernel. I started googling and only found some info on the KT Kernel without much luck on the other two. I also discovered that there are other kernel options for the Galaxy S4 which can be changed after the ROM has been installed.
I guess my question is, what types of features do these kernels offer and are what are some of the advantages of using one over the other? I don't plan on keeping the stock Samsung kernel because I'm sure there are other benefits to using the 3rd party ones, but I have no idea which one I should pick, or where I can find out more information.
Or, if there's a link to a resource I missed that would answer these questions?
Thanks guys!

Go over to original development. There are 3 threads for kernels there. There are versions for touch wiz and AOSP 4.2.2. As well As 4.3. Each have their followers. Honestly they are all 3 very good. Try them all and see what works best for you.
Then if you run me7 based roms, I believe the elite kernel is the only one That have the smart features working correctly. But it has an issue that you can't charge the phone with it off. Have to do a battery pull to get it turned on again.
I will say that ktoonsez kernel has a nice app built in to tweak settings. Also a link in the op to a guy who keeps up with his kernels so he has all old versions also some pre-configured settings for the kernel you can download and apply.
