(Q) i9100 kernal porting - AT&T Samsung Galaxy S II SGH-I777

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.

Obviously hellraiser won't work, the kernels are incompatible for one thing

International models always come first as manufacturers can do as they please with them and not worry about carrier interference. Devices like ours get official updates after our carrier has their hand in it (mainly to add bloatware and lock us out of certain features they don't want on their network).

Is there no ICS kernel for the i777? Can't we mod the GSII kernel to work on our device? Pretty much the only difference between our devices is the trackpad.
1) Not development
2) Nothing is going to happen until ICS goes official for I9100, try searching
Why is this in the dev forum?? Have you looked/searched through general forum? There is already a sticky on ICS and a thread about CM9. Read through both of those threads and your question has been answered numerous times. NOTHING CAN BE DONE UNTIL OFFICIAL SOURCE DROPS.

Guys the only thing not working if you flash the int version is touch keys and in call audio apart from that if u want a tablet it works perfect.
Also, kk6 modem works with it fine.

And how can those be fixed?
The phone isn't usable without any of them.
Touchkeys and incall audio are MAJOR issues.
Touchkeys are an EASY fix with kernel source - but due to the structuring of the kernel code, they are NOT fixable without it. (Unlike the Captivate/I9000, where I9000 kernels did pass the keycodes on to userland for the extra touchkeys - I9100 kernels don't.)
Working incall audio when the touchkeys are broken is kinda pointless. Also, it's VERY likely that incall audio will require some mc1n2 tweaking to work around the lack of I777-specific audio libraries. (e.g. the "swap the libraries" trick from Hellraiser won't work.)

Slightly off topic, but why would or what would make Samsung elect to change the way the kernels work like they did from Captative/I9000? I mean the I9100 and I777 are similar(same cpu, etc) like the I9000 and Captivate are.
Btw, I'm sure this is a question you've struggled with too, but wouldn't it be easier for samsung too? One less thing that needs changing

Current CM9 builds are using hacked Gingerbread kernels (correct), and as such we have sources, meaning that even if the Hellraiser hack mods userland files, the touchkeys could be fixed with a kernel mod, correct? I know you won't work on it as its a lot of work for a temporary hack, which I understand. I'm just wondering from a technical perspective if its possible?

If it isn't too difficult to explain, what do you mean by "lack of i777 audio libraries"? Do the i9100 and i777 use the same DAC(the mc1n2), and do they use the same audio libraries? Is it just that the use of different libraries would require more in-depth tweaking than Hellraiser does currently, or just an i777 specific build?

Not unless something has changed - they were using hacked GB kernels and had VERY bad results. Every recent release (up until codeworkx stopped releasing because of the noobs) used an initramfs repack of an I9100 ICS kernel.

Same DAC, but the wiring of inputs and outputs to the DAC is different. This is why microphone audio in calls is screwy when you run I9100 audio libraries on an I777.
The easiest and most robust fix is to swap in audio libraries from an I777 like Hellraiser does. However, since we don't have I777-specific audio libraries that are compatible with ICS, we can't use the easy way out that Hellraiser did.

[q] whats the diff between glitched and stock

So I was browsing through the forums for my answer and I can't seem to find it. I've been using aokp builds for countless months (i just didnt count) updating and enjoying new feature updates and this and that. Only, one day I hopped onto the irc chat rooms because I found something exciting and new I didn't know about and wanted to ask some questions. I hopped into the room where some aokp members hang out and asked them about incorporating some of the features of icy glitched such as a software ghost key fix host mode and a few others and they seem intrigued. Next thing I know roman or someone dumps a link into the room and boom there's a build for aokp glitched right infront of me for the fascinate and every other samsung galaxy s device.
I feel like some of my questions are still floating around my head unanswered though. I know that glitch brought some kernel fixes to the mod, but what exactly is the difference between the new stock milestone aokp and new stock milestone glitched? Other than the fact that one has the glitched mod and the other doesn't obviously.
I just want to know the advantages and disadvantages to flashing the stock milestone 5 vs glitched milestone 5 with regards to battery life, performance, kernel version, features? What's the point of having two I just don't get it I guess?

the difference between glitch and no glitch:
ability to overclock
50mb of extra ram freed
callboost script(fixes speakerphone echo)
data fix script(fixes datadata issues some speak of)
phantom key popup fixes
I believe there might be a couple things Im missing, but look over the changelog in the icy glitch thread.
So if i'm understanding this right, they both have the same version of the linux kernel but glitched just has a different boot loader and different features from that mod? I don't know why there'd still be a stock cm aokp rom then because isn't glitched for the fascinate MUCH better with battery life underclocking during idle, better jpeg indexing? some stuff like that idk but it was performance based and a few features like usb host enabled and phantom keypress fix.
I just want to make sure i'm not missing out on something by sticking to glitched aokp builds. I get better battery life than I was ever getting before but that doesn't mean it can't get better
Nope you got it. Glitchy > stock aokp.

if you flashed the glitch build then there is no point in flashing glitch v14, you already have it. the only difference is glitched aokp has blue recovery instead of red. every since the upgrade to kernel version 3.x folks had issues with nandroid restore bootloops with glitch red recovery. you are set no need to do anything else...enjoy
Go for it...

what kernel should I choose?

What kernel do you guys like to use with jelly beans or any ROM for that matter?... I dont really know what the differences or have the time to try them all out so ive been using the stock kernel. If anyone could share shed some light on this for me that would be great. Thanks a lot!

Kernels are kind of limited in this phone's development, but very high quality. I would say it depends on preference. I have tried them all, perseus is a kernel that hasn't seen an update for a while, but is one of the only 2 ExFat kernels that allows for Overclocking to 1.8ghz. PBJ is another just like it by Imnuts that doesn't feature overclocking but Exfat as well. Devil Kernel is a kernel that allows you to flash it onto either an AOSP or a samsung touchwiz rom, so its very useful and allows for audio increasing and overclocking to 2ghz stable. To prevent this thread from getting locked on biased favoritism, Every kernel that is available is good, some have stopped development, and some get it every day or time its needed, try a few and see what you like.

[Q] Stock TW 4.1.2 kernel

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.

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.

my bad GPFERROR. good eye in finding that
I had a nandroid of the stock 4.1.2 ROM so I just went into TWRP and restored only the boot image from the stock ROM which gave me the stock kernel. Everything is working fine.

i have been running phase kernel on stock rooted 4.1.2 for months and have never had issue with lights not working. are you sure its not a rom issue. and the obvious did you check to make sure touch key lights are not turned off?

****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.

What Kernel should I use?

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!

I'm using KT's kernel and find it very good. I will provide a link that will help you set it up. I'm using the nightmare to remember settings and I'm getting killer battery life and great performance!

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.

Try different ones and see which you like most. IMO none of the custom kernels hold a candle to stock. Its well balanced between excellent battery life and great performance and its rock solid stable.

Thanks guys! I've tried KT Kernel and I may stick with that. But I'll double check in original development - I must have missed the threads there!
