Kernel - Galaxy Ace S5830 Q&A, Help & Troubleshooting

Im wondering why all the Android kernels are so old? For example: ive the newest Rom for the ace (thanks to wayland) but it just has a 2.6.y kernel. Even backtrack, blackbuntu or ue have old kernels (3.2.y-3.5.y) . So my question is : why does no one use the 3.7.y or 3.8 kernel ?
Sorry if this is a stupid question i dont know much about it
And sorry for bad english

Wine tastes better the longer you keep it. Many of the kernels are unique in their own sense as well as stable. That's why we still use them !

Our Ace has some hardware limitations and it is very difficult task to port 3.x kernel in our ace.

thanks so would it be possible to get kernel 3.8 rc2 to my backtrack?? cause wlan and eth drivers are not working for my lenovo ideapad y580 in the official kernel

[Q] Can I OC/UV with Darky's Rom 9.5 ?

Hey guys, I got my new Galaxy S two days ago, already optimised it and installed the new Darky's Extreme Edition 9.5 custom rom. Now I want to undervolt and maybe overclock my SGS. Is this possible with this custom rom ? Do I need a special kernel or can I just use apps like setcpu or voltagecontrol ?
greetings, Sir Kasimir
Probably but yet again you need to ask Darky .

I think that you can't OC on darky's rom. I know that it is available in ultimate rom but for darky I'm not sure.

Possible on every ROM.
You just need a kernel which is capable of OC/UV and app to control it.
Ok, thanks for the reply.
That means I can use a different kernel with this rom right ? Now I need to know what the Dark Core Kernel does and what the advantages/disadvantages of the different kernels are.
Search xda and decide what kernel suits you best

From what I have read, it doesn't seem that Android 4.1.2 adds much to the table from what we already have with currently Jellybean ROMs and Semaphore kernel has already been updated to the same Linux build as in this ROM.

No alternative kernels for p970 Jellybeans?

I've been looking around for p970's kernels and it seems there really isn't much. Let's say if I flash a kernel specific for another device, say SiyahKernel for S2 onto my p970, will it work out?
It's different specification, you can't install other kernel to P970, or you'll only got hard bricked..
That makes me think of a question... If kernels got the same arch, commits can be injected or is it more complicated than injecting commits and managing dependencies?
And adapting some data like ram size...

RR kernel is an alternative . But chaux please wait for ics sources . Now our community is in the phase of freeze after ics sources is out devs will get diging

Install captivate rom on galaxy s

I understand that the samsung captivate is a variant of the i9000. I know examples of phones that has almost the same hardware and can use the same ROM but with the correct kernel: the htc hero and htc magic is almost the same hardware, one rom will work on both but will use different kernel in each other. the huawei u8800-51 and the u8800pro have the same hardware, the diferences are that the pro uses an updated version of the procesor (u8800-51=qualcomm msm7230; u8800pro=qualcomm msm8255) but compatible with the same libraries. Motorola defy can use ROMs made for the defy+.
what's your opinion about this? do you think is possible to install a captivate rom on our galaxy s and viceversa?

Not quite so apparently. The reasoning and the mechanism behind it I don't know why, but cross-flashing doesn't seem to work between the SGS and its variants. It doesn't even happen between the S and the S+.
Having said that there ARE a few roms which can be installed on both the S and the Captivate from the same zip (Helly Bean is the best example of this). That relies on Aroma however, so its not quite the same thing.

You can veery simply port it over to the i9000 with a few steps. There should be a thread in the q&a

[Q] Kernel based on 3.4 or higher

Hallo,
I want to ask the devs if there ideas to build kernels based on higher kernel versions. My former phone (S plus) had a 3.4 kernel which had good influences on performance.

Kernels can only be built if the source is released .
But I guess the sources of the kernels are open since these are Linux kernels. Anyway the devs of the S plus also managed this. So it should be possible for the S3 too.

Noone an idea? Also Kitkat (CM11 unofficial) runs with 3.0 kernel

Yeah, you're right. Devs in Galaxy S Plus i9001 built the 3.4 Kernel, but it was not easy and took several months to build stable kernel.
First kernels were built on LKA sources and they switched to CAF.
They also built BIGMEM kernels - Standard kernel RAM was ~350MB and with BIGMEM kernel it could go to 370 (still all was working) and 390 MB (in this case 720p recording was broken).

I know that all. My former phone was a S plus.
They really made a great job. So could it be possible to use the sources of the developer team and port them to the S3.
The 3.4 kernel runs so well. Its really great
