[Q] Kernel based on 3.4 or higher - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

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

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

Kernel

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] Using stweaks cyanogenmod 10.1 i9305 Alpha

I am using Codeworxs Cyanogenmod 10.1 userbuild.
http://forum.xda-developers.com/showthread.php?t=2084604
On first page larryTheCow says Kernel is based on Perseus but when i start stweaks the following message appears:
Sorry, no kernel support!
Anyway, is there a way to use stweak to modify cpu/gpu voltage?

No but Liquid Smooth has the option inbuilt however I don't believe it is currently functional.

It's not possible. Perseus kernel is for samsung based roms only.
At the Moment there is no Option to modify cpu/gpu voltage an the Frequenzy in CM Kernel , CM 10.1 and Liquidsmooth is CM Kernel

Favorite custom kernel and why?

Hi I'm new to the cappy forums and want to see what perks and such there are in the custom kernels, so I'm asking what custom kernel are you using ( if any) and why that one, is it because of features, stability, performance, etc.

I mainly use Nick0703's Unofficial Semaphore because of Step OC and In-Call Volume settings.

For your Xylon 2.3.3. ROM use "sc" or "s_vc_c" version (with Voodoo Color).

What exactly is the difference between sc, vc , c, and s?
At My main phone's forums (Samsung infuse 4g) we don't have any custom kernels yet, one is in the works but that's it so flashing custom kernels is kinda new for me, so any details would be great. Also I am very thankful that you added in which type I should be using for my install ROM, I flashed devils kernel to try out, and thinking about trying the dual boot one, but I want to find out add much add possible about the advantages and disadvantages of the different kernels before choosing a daily driver.
Sent from my SGH-I897 using xda app-developers app
Normal version "c" is for most ROMs, version "sc" is for Slim based ROMs. Your Xylon 2.3.3 runs better with "sc" version.
"vc" stands for Voodoo Colour mod. Download Voodoo Sound app from the market to have VS/VC control.

Which version of the unofficial semaphore should I use with the PAC MAN ROM?

based off of the post above yours i would say "C" cuz if im not mistaken PAC is primarily CM Based, but i would wait for actual confirmation before proceeding
I don't remember what kernel version PAC uses, but just install the ROM and look what kernel it comes with. PAC ROM is ported by the same dev - Nick0703. Most likely the default kernel is already his Unofficial Semaphore, therefore no kernel change needed. PM him to confirm.
If you come from a CM ROM the kernel will stay the same.

This is what the dev said
"You can use any version that you want. But if you're using the "s" version then you'll need to flash HugeMem libs also."

Which Kernel is the best for KitKat?

Hello. I tested many Roms and Kernels and i cant choose one. I'm using Cm11 but i think its kernel is slow. Semaphore? Mackay? CyanoCore? Meybe any other? Which Kernel you preffer?
kernel
I prefer Semaphore. Good kernel with many options, bigmem etc. CM 11 work fast on it.
I've used Mackay since... Well, a long time. The reason I prefer it over Semaphore is its capability to send MMS. I can't send them with Sema, though a good kernel it is otherwise.

Mackay. Latest version have CMA with 416mb RAM for users with 720p playback/record
how to enable 416MB?

I recommend u Mackay Kernel 0.607 works best on CM11
Go for it
Read rules.There's no best kernel/rom.Test and see which fits you best.
