By installing this, you'll receive no support from Stratosk because;
This is an Unofficial Semaphore Kernel
Stratosk does not support it
So do not bug him if you have a problem with this kernel. But bug me instead!
If you guys want to see some more features added to this, feel free to tell me and I'll try my best to add them to it.
Please note that there are 3 variations:
Normal versions: for CM10 or ROMs without hugemem configuration, available RAM 384MB - 396MB
"s" versions: for Slim Bean ROM or patched ROMs with hugemem configuration, available RAM 397MB - 409MB
"vc" versions: is Voodoo Color Mod

How to:
How to enable Swap?​
To enable Swap, you'll need to create a swap partition on you External SD card. I recommend following this guide for it. http://forum.xda-developers.com/wiki/SD_card_partitioning
1. Make sure to backup everything from your SD Card first
2. Do not reformat your SD Card while it's still in your phone, take it out and plug it to your computer through a card reader!
3. I recommend that you only create a Swap Partition around 256MB
4. Follow that guide and when you reach to Step 3, select the option "Linux Swap"
5. When you finished following that guide, plug in your SD Card to your phone and Reboot to Recovery
6. Then flash this zip Enable Swap
7. Reboot your phone and you should be good.
8. To make sure Swap is enable, go to Terminal Emulator and type "free".
9. You should see some info at the bottom about Swap.
How to Enable Zram?​
To enable Zram, go to (Settings -> Performance -> Memory management.)
Or Flash this zip Enable Zram
How to use the OC'd Steps?​
To use the OC'd Steps, use Nstools or CM Performance Settings (Settings -> Performance -> Processor -> Maximum CPU frequency.)
If the chosen Frequency setting is not sticking with Nstools or CM Performance Settings, try using CPU Control Lite or Voltage Control.
I flashed the "s" version and now 720p recording or playback is not working?​
You'll need to flash HugeMem Libs first and then you should have your 720p recording or playback working again.
How to get rid of the Green Screen Flash and get the best colour if using VC version?​
To get rid of it, I recommend using the following Voodoo Color Settings. To change them, use Voodoo Sound app (Available from the market).
Color profiles
Voodoo profile v1
Screen RGB multipliers
Red: 286xxxxxxx
Green: 333xxxxxxx
Blue: 392xxxxxxx
Screen v1 gamma hack
*Reset to 2.3.3 Then Change*
Red: -26
Green: -30
Blue: -33
Or use this gamma hack (Might get the green screen flash but with a better looking colour, thanks to aduka)
Red: -40
Green: -40
Blue: -31
*If you're still getting the green screen flash, increase the "Screen v1 gamma hack" by +4 for the red, green and blue till you stop getting the green screen flash*

Do you suggest any changes to voltages if running this at 1200?

By default I've increased the voltage for the 1200MHz step to 1350 mV to make sure it's stable for everyone else as not every phone is same. But once your phone is stable at 1200MHz, you can undervolt the voltage until you find a sweet spot.
Like on my phone, I was able to undervolt the 1200MHz to 1275 mV.

I UV by 50 with this kernel and devil kernel the same. Stable enough for me
Also. Nick0703. Sorry for posting in Stratosk thread regarding your kernel.
I was wondering how to make the 1200mhz stick. I tried through settings and then tried with nstools. No go on reboot.

I'll upload my NsTools settings and you can try that. I'll do it like in an hour. As right now I have some other stuff to do.

Hey Nick0703 would you be able to get screen off min 100mhz max 400mhz settings into the kernel or is it not really needed? I guess it sits at 100Mhz idle. Also, are you able to deep idle? BTW 1200 is optional but it wont stick on reboot still. Your settings disabled nstools to default.

Re: [KERNEL] Unofficial Semaphore JB 2.9.8.c
Try cpu control lite or voltage control if the settings do not stick.

I could add the screen off min 100mhz - max 400mhz to the kernel but I don't think you'll see any difference from it. But I compile a test version with that option and see if there is any difference. And yes, I'm able to deep idle. Deep idle works fine with my phone but keep in mind that not all the captivates are the same.
And for the 1200MHz, try using CPU Control Lite or Voltage Control just like sephhi stated.

Thanks guys. Good looking app but it didn't work. Not sure why. Always able to set to 1200 on devil kernel 4.1.2

Re: [KERNEL] Unofficial Semaphore JB 2.9.8.c
Version 2.9.9sc has been compiled. But it will need to go through testing first as the kernel configuration file had some few changes.
I'll need 2 people to test it. If anyone is interested, send me a PM.

Perfect. Got it to stick 1200mhz! What boot loaders do you use Nick0703? I'm wondering if i9000 loaders would help with deep idle.
Would suck if it's just my phone.

It works! Can't say if it brings any performance advantages for now, will be testing it for an extended period first. Nice boot logo in B&W, clean and simple. No zRam options in Performance Settings (not an issue for me, I always turn zRam off), no Step OC in Performance Settings (this is an issue for me, I run 1200 step OC by default), In-Call Volume Controls in Advanced Settings (very useful, the reason I was always flashing Unofficial Semaphore), KSM enabled by default in Performance Settings, default CPU governor - ONDEMAND, default I/O scheduler - NOOP (exactly what I prefer and what gives best performance on my i896).
Thanks Alberto96 for sharing your work with us! :good:

Great!
Not sure why though but I'm getting SOD's almost immediately when screen goes off.
I'm running CM10 latest nightly (no SOD with stock kernel). No OC.
p.s. I'm new to captivate so i could be doing something wrong...
EDIT: played with a few settings and seems to be ok now. Might have been deep idle enabled causing it...?

Thanks, good to know
So far this kernel rocks!!! Been running it since yesterday and its been super smooth with no bugs.
The only thing I need to figure out is a way to reduce the amoled saturation (Ariesparts.apk doesn't seem to be able to do this...)

Well v04 is the stuff love it well fast and smooth all I got to see now is battery life and that takes a day to test man your work is off the hook

[Q] Overclock

Hi!
I'm very confused now. I have find out that devs have had really hard time trying to overclock s5360. I have been told that only Merruk 2.5 (OC 1.2Ghz) kernel is really overclocked and others just look like overclocked but they really are locked to 832Mhz. Is it really so? Is Maroc-OS's previously beta file (900Mhz) just placebo?
EDIT:
Here is Maroc-OS's answer to question: "Is the OC real or not?"
Background:
SGY has BCM21553 CPU which is running at 832Mhz with two frequencies (312Mhz, 832Mhz) as default. However there are some devices which are running at 1Ghz by default with the same CPU (BCM21553). That is why Maroc-OS wanted to OC his kernel.
First of all irfanbagus made a patch for s5360 to open additional freqs. Then Maroc-OS made a merruk beta file based on that patch. With that beta file you can "OC" stock and Savie #73 kernel to 900Mhz. However Maroc-OS and other devs found out that the beta file was not real OC because you can't OC BCM21553 with irfanbagus' patch. You can only add lower than 832Mhz freqs with that patch. Then Marok-OS decied to make new kernel.
Marok-OS built Merruk 2.0 which is "OC" to 1Ghz but again he found out that is was not real OC. Then he decied to try OC by different way. After much development Maroc-OS realesed first really overclocked MerrukTechnology Developer Edition V.2.5 kernel. However some people started to argue that even Merruk V2.5 kernel is not real OC. You can read the whole conversation about that starting from here to here. Maroc-OS made pretty clear that OC is working.
Then everybody noticed that AnTuTu or any other bechmark scores didn't raise up with OC (like they should). Some tester said that they can feel to faster performance and some people say that they didn't. Here Maroc-OS say that the OC doesn't work correctly but I guess that means that the kernel is not stable yet.
After same serious work Maroc-OS realesed updates to his V2.5 kernel and some people report better AnTuTu scores. Still there were some devs who said that OC is not working. Maroc-OS's final aswer to that argue is here.
That answer is what I find interesting. Maroc-OS said that the OC is semi working. When the freq is changed to over 832Mhz (1.248Ghz for example) the CPU tries to change it back to 832Mhz. Maroc-OS made the kernel to change freq back to over 832Mhz as quickly as possible. That means:
Maroc-OS said:
when the governor try always to swich to it randomly and back to 832 if he did it 20 times in a sec we got it working but not fully working one )
Click to expand...
Click to collapse
So the freq is jumping between OC freq and 832Mhz. That means that OC is semi working. Maroc-OS wanted to make it fully working but never got that far because he just left from here xda.
However people didn't stop talk about is OC real or not. Here is people's opinion (link, link, link) You can read more starting from here to here. Then continue reading from here to here. Then you can check from here to here. Lastly you should check from here to here
This is the last post where Maroc-OS say something about OC.
Then let's talk little bit about other OC kernel. First one after Merruk kernel was Maroc-OS team member Mohamed.Anwar with eXtreme kernel (OC at 1Ghz). This is what Mohamed.Anwar said when Maroc-OS left. After all it turns out that Mohamed.Anwar used irfanbagus's patch to OC like Maroc-OS first did with merruk beta file. That means that eXtreme kernel is not real OC kernel.
Then there were Eve's kernel. The dev itself say that he/she doesn't know if the OC is working or not. He/she used some sources from Merruk kernels but I don't know is it really working or not. Many people say that is not real OC. Then there are Jarvis kernel and AXIOM kernel but they are based on Eve's kernel. Again, many people say that they are not real OC.
So you have to make your own conclusion about is the OC real or not!
Ps. The latest and most stable Merruk V2.5 #206 can be found from here and here but the latest modules are here.

most likely any oc is a placebo in 5360 - when I tested it I noticed no difference in performance
The phone may report its overclocked but most likely it isnt

Can you tell me why they (OC) are placebo? Does it have something to with that bcm21553 has some lock code at 832Mhz? But why there are phone with same CPU at 1Ghz? If those phones are 1Ghz why s5360 cannot be oc atleast 1Ghz?

Jarvis v2.2 #29 (1.2Ghz): People say it's not working --> Not working? (Any proofs bogoMIPS or FLOPS?)
Merruk 2.5 (1.2Ghz): Some people say that it is the only one working and some say it's not working --> Works? (Any proofs bogoMIPS or FLOPS?)
MerrukTechnology 2.0 PRE-FINAL (1024Mhz): I don't know
Merruk beta (OVERCLOCK SGY.zip) (900Mhz): People say it's not working but bogoMIPS shows 900.05 (tested myself) --> Works?

You are wrong. OC may decrease your phones lifetime but manufacturers never push their products to their limits. There is always possibility to OC little bit but not too much. Too much OC will harm your phone. But we can do always something. Proof of that with bcm21553 is that there are phones with frequency 1Ghz by default.

So should'nt I use custom Governors or I/O Schedulers?

Proof it!
I have now read to whole development thead of merruk kernel. I figured out that there are only couple guys saying that oc is not working. Maroc-os and others never said that is not working. I'm not dev but I figured out that there was some problems with bcm21533 lock code (HW something) but I guess that mMroc-os made it (semi) working. So why people are saying that it's not working. Where are yours proof?

someone took into account what I said? Would not there a way to check the cpu clock? I tested the kernel merruk and Jarvis also both when applied 1248Mhz literally accelerate small GY.
Not so dev but if I remember well the only thing that prevents the oc Gy would not that file apuclock something? (remember that time does not move with the gy sources).

Try this.
http://forum.xda-developers.com/showthread.php?t=2384985
overclock to 1.2GHZ.

Simple way to check is first be at normal 832MHz and do a benchmark.
Then switch OC kernel and set OC at max. Do another benchmark.
DO NOT BLAME ME FOR ANYTHING BAD HAPPENED TO YOUR PHONE. DO AT YOUR OWN RISK.
Compare both benchmark scores.
That will sort out the thing whether OC is real boost or just a placebo.

I would like to open this thead again now because Maroc-os is back! I have tested all these oc kernels and they are good, no doubt about that. Thanks to the devs! I'm just wondering that are they really overclocked over 832Mhz ? I mean they are great but is the faster performance effect due overclocked frequencies (over 832Mhz) or something else? It woudl be really nice if Maroc-os and other great devs would say something about it.
Here is the list of oc kernels (what I know):
- Axiom 1.0 (1.2Ghz)
- Eve.121_4 (1.2Ghz)
- Jarvis v2.2 #29 (1.2Ghz)
- Merruk 2.5 (1.2Ghz), MerrukTechnology 2.0 PRE-FINAL (1024Mhz), Merruk beta (OVERCLOCK SGY.zip) (900Mhz)
- eXtreme Kernel (1.0Ghz)
Ps. You can also "overclock" stock kernel and Savie #73 kernel to 900Mhz with merruk beta file. (check this post)

Thank you for this kernel!

After switching to custom kernel, I just now re installed on your Temasek ROM.
And I still can't change the maximum CPU frequency.
I like to keep my frequency at 1.5 GHz max to decrease heating problems.

yes because no changes in source.., it's a bug., hopefully it'l be fixed in future update(s)

Wifi broke after flashing on Beanstalk.
Any quick workaround for the time being?
Edit.
Suggest me a Gov and I/O Sched for balanced performance and battery. Thanks

OK. Plus the Vainglory game performance is laggy at maximum frequency too.
Issue is mostly with stock CM kernels, doesn't happen with almost any custom kernel in general. I can play the game smoothly at 1.5 GHz frequency.
The frequency and gaming lag issue keeps me away from using CM ROMs unless there is a good custom kernel to fix issues.
Will be looking forward to a improved build :good:

Slow charging!
it's a great job you have done. currently using your kernel. everything working fine except the very Slow Charging problem.
Please add support to the MIUI 7.0 marshmallow rom also thank you

I got random freeze with the kernel. I had plan to upload kmsg before but I installed custom kernel and left it. Although the custom kernel I installed itself already has freeze issues. And reinstalling this kernel again there is a freeze.
I have attached kmsg before installing custom kernel. Had to rename extension to docx to upload here.
BTW in temasek ROM. FM Radio on every boot asks root permission. And it doesn't remembers whether I said yes or no despite checking the check box of CM root permission. And whether I choose Yes or No. I get toast message afterwards that selinux set to permissive.

Support to the MIUI 7.0 marshmallow rom please

Very nice kernel! Excellent job! Please add miui support

Does it support MIUI KK?

Any plan to add oc ?

any update soon ? Thanks

Either it's a skill test, and one needs at least to be able to compile kernel to use this one
or maybe AuxXxilium wants to test it a bit more, before releasing it into the wild^^
