[ NOTICE ]
from v02 onwards just flash the kernel package through recovery and wifi modules will automatically be updated!!
since i have changed the kernel version string stock wifi modules will no longer work on my kernel...
if u try to enable them on my kernel u will get "ERROR" while starting WIFI...
i will be providing modules for my kernel which HAVE TO BE FLASHED VIA RECOVERY for wifi/bt (and other things) to work correctly
stock modules will also be provided which again will have to be flashed via recovery if u want to return to stock kernel
remember i have already told this to u guys... if i see some users reporting that wifi is giving error because u did not follow my instructions ur post WILL BE IGNORED....
some user may still suffer from "ERROR" while starting WIFI, even after flashing the correct modules via recovery, that is because of the initial pre-rooted system.img files, which dont have any space left on the system partition... to solve this issue reflash the stock system.sin thru fastboot or thru flashtool... my kernel will auto-root it so u dont need to worry about rooting and now u will have space to flash the wifi modules...
(thanks to kazuni for pointing it out here)

OR
use the Advanced Stock Kernel posted here
FOR OVERCLOCKING
start SetCPU/NoFrills CPU Control app on ur phone (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
SLOWLY increase the frequency one notch at a time and do stability/testing for few hours
[ tips / recommendations ]
for better battery life try undervolting... start off in steps of -25mV and see which is stable for u... for my phone -100mV was stable...
before u report any battery drain issues please read this:

this will work on any of the current GB firmwares of Sony (.63/.67/.73)
wait i will update first post!!
please use this thread for reporting issues/bugs ONLY

Everything works fine (touch recovery is nice) only issue is that your Wifi modules are not working on 67 UK FW. I just get an error written under the Wifi toggle in settings.

hmmm... u mean the stock wifi modules package? or my kernel's wifi modules?
also post output of this:
Code:
adb shell md5sum /system/lib/modules/bcm4330.ko
the output should be:
Code:
6b0186d43b54207e54c509a795035ad4 /system/lib/modules/bcm4330.ko
if not then reflash the modules update.zip using recovery
BTW i have done testing on the 6.0.A.3.73 SG firmware

recheck ur busybox installation...
try this...
take full backup of ur current rom in recovery...
flash FULL stock FTF of the firmware u currently using..
then just flash my kernel and get into recovery and flash the modules...

Yeah will do. if you remember i had busybox issues on bin4ry's 67 root img. would not install even manual adb. Think most likely an issue with his img. Now we have auto rooting much easier to update so will give that ago.
EDIT = Flashed Generic 73, wiped it all and now your Kernal and WIFI is working fine Thankyou. Sorry for filling up the thread but at least people know if on Bin4rys 67 root and having issues. Flash different FW first.

Hi doom,
it seems update file for wifi is not working with recovery, I already check up, after install wifi module for your kernel via recovery, wifi module still the same as stock version.
And also superuser is not working too, maybe it failed because my phone already rooted.
Many thanks for your work
edit
Just install again your kernel with unrooted stock rom, everything is working great
Thanks again

That's because the preroot image that binary posted is having the exact issue I had first time I made my preroot image - there are not enough space in the system partition (there is, physically, but not logically).

I present to you
KA Xperia SSpeed kernel v8
04/01: Xperia SSpeed kernel v8 released & changelog updated on 3rd post
Please hit the thx button if you like my kernel ​
Dear Xperia S users,
This kernel is based on Sony's ICS stock kernel sources. I'll continue to add more features to the kernel in the future
This kernel is specially made for my rom: KA Xperia SSpeed. Maybe it will work on MIUI, but it should work on stock roms
I hope you enjoy my kernel
== features ==
- All featuers of ICS Advanced stock kernel (pre-rooted, recovery, init.d support etc)
- Added lot of things for better performance
- Extra governers: Pegasusq, Hotplug, Lulzactive, Smartass2, Badass, Lagfree, Interactive, Wheatly
- Extra I/O schedulars: vr, zen, row
- Voltage Control (undevolting is possible)
- 1.89GHz OC
- Zram
- And a lot more
== download == Xperia SSpeed kernel v8 ==
For Each kernel there are 3 versions:
- Normal: 1.5GHz speed recommended if you don't want overclock, but just the optimizations
- Speed: 1.7GHz, perfect if you want safe overclocking.
- Performance: 1.89GHz, this is if you are an overclocking junkie Don't expect it to keep your device cool, it will heat up when doing heavy games etc.
The kernel is in the folder for your device, then choose the version you'd like to download
Mediafire link: KA Xperia SSpeed kernel v8
XDA Fileserver: XDA Fileserver mirror
I kindly ask everyone not to mirror my download links. Thank you
== Important information ==
- Overclocking is a risk, be aware it can harm your device if you do things wrong. But don't worry, every freq below 1.7 Ghz won't harm your device
If you install a new kernel let it settle for a few hours first before overclocking to high speeds
== credits ==
- Arakmar for ramdisk and all his work on advanced stock kernel
- Doomlord for his work on Xperia 2012 kernels
- Sony for kernel sources
- And everyone who helped Doomlord realizing his work
== Installation instructions ==
Important! Only for unlocked bootloader
1) Flash the kernel in recovery:
2) Enjoy it!!
I am not responsible for damage to your device, use at own risk!

If you install a new kernel let it settle for a few hours first before overclocking to high speeds
== credits ==
- Arakmar for ramdisk and all his work on advanced stock kernel
- Doomlord for his work on Xperia 2012 kernels
- Sony for kernel sources
- And everyone who helped Doomlord realizing his work
== Installation instructions ==
Important! Only for unlocked bootloader
1) Flash the kernel in recovery:
2) Enjoy it!!

My bootloader is locked. Maybe that's the reason why it won't boot I guess. :crying::crying::crying:
Update:
It's working. I just unlocked my bootloader and it's working now. But why is the performance zip is max of 1.8Ghz?

No probs. Yes it is 1.89Ghz. I thought performance has a max of 1.7Ghz? . Oh by the way, is there a chance to upgarde the recovery to be the same as the CM recovery (which has ext_card support and others)?

I guess we can use the ROM of XS but losing the ext_sdcard functionality.

I don't know man ever since I've been using this kernel I'm getting random freezes when browsing on Chrome/Firefox, idk if it's kernel related but I'm using stock .55 ROM. Had to force restart my phone in order to get back

Point to note
In S Version , Hugemem Libs must be flashed for 720p record to work
In both versions , ticking bigmem will break 720p recording.
Tar version must be flashed with Odin/Heimdall , zip with CWM/TWRP.
I expect to get more features in the differences soon, including ISO CDROM functionality , normal OC ( upto 1400MHz ) and other features.
This build will be updated when stratosk makes new version , or when I have lots of new additions.
All bug report of this kernel must be posted in this thread , please do not disturb stratosk regarding this kernel.

ARM Coresight is a tool used to debug and trace issues in ARM based processors. It unnecessarily adds a load to the CPU , so I disabled it.
For XZ Compression you can read it here - http://en.wikipedia.org/wiki/Xz

I once asked Stratos why he doesn't use xz, and he told me that he uses a better compression method. Anyways, good job and have fun with further development of your kernel!

Thanks for the info . I will try both and decide then.
I am going to upload build which will change the name of the kernel to something else, as stratosk doesnt want the name Semaphore in the kernel.

a god thing would be autopatching 720p libs like derteufel
this would be a great advantage compared with original semaphore

A god? You can always pray for that to happen!

Since they are 2 versions , s and non-s, this can easily be rectified by adding the Hugemem libs in the zip.
Will do it soon.

Re: [JB 4.2][KERNEL] Unofficial Semaphore+ (name to be changed soon)
Oh... So this is what you pm'ed me about. I see. So, is there gonna be a nolvm version?
Awesomenesss!!!

Swap would be good im missing that feature since devil kernel
i hope you add that feature

Since it is based on Semaphore sources , it can be controlled completely using Semaphore manager.

given away my Xperia S to other devs... so friends as promised here i have given away my Xperia S to @nickholtus & @Achotjan ...
I hope they will work on this device and continue developing for it... I am really sorry that I couldnt spend a lot of my time working on this amazing phone..
since I no longer have the device with me, I will not be continuing any development work on it...
with this I am closing this kernel thread...
it was great working on this device, one of my favorite devices and I will surely miss this phone and the great Xperia S community which always supported me and my work!
I hope that I will meet some of you around on XDA in other device communities perhaps...

stock JellyBean FW
.96 - v6
.211 - v5
.200 - v1, v2, v3, v4
bootloader unlocked
working fastboot
android app for overclocking like Kernel Tuner (free), SetCPU (paid) or NoFrills CPU Control (free)
[ how to install my kernel ] (via recovery)
download the kernel package update.zip
save the package update.zip to sdcard (of phone)
reboot phone and enter recovery
flash the kernel package update.zip
reboot phone and enjoy the kernel
[ how to install my kernel ] (via fastboot)
download the kernel package update.zip
save it on c:\ and extract the kernel.elf from the package
save the kernel.elf to the folder containing fastboot binary
flash the kernel.elf using fastboot:
Code:
fastboot flash boot kernel.elf
reboot from fastboot
Code:
fastboot reboot
the device should now start booting, enjoy the kernel
[ how to root device? ]
I have disabled auto-rooting in these kernels...
to fully root device (Superuser + busybox) just flash the following file in recovery:
SuperSU-1.25-Busybox-1.20.2-UPDATE.zip - 1.43 MB
FOR OVERCLOCKING
start SetCPU/NoFrills CPU Control app on ur phone (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
SLOWLY increase the frequency one notch at a time and do stability/testing for few hours
[ tips / recommendations ]
before u report any battery drain issues please read this:
[GUIDE] HOW-TO Properly Evaluate Battery Life and Provide Useful Reports
faux123 has posted very nice info regarding most features
[ my kernel sources ]
Just a statement regarding kernel source: The Kernel Source is released for all at GITHUB repo given below. BUT Free software does NOT mean no work or time was spent working on it. A lot of my free time has gone into patching/testing this kernel/features integrated in this kernel. If you use my modified kernel source in parts or in its entirety, I kindly ask you mention its origins and to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source.
Thank you !

How to use CPU Voltage Control interface
All credits for this interface go to Faux123!
device will always bootup at stock voltage table...
WARNING!
DO NOT USE TOO HIGH OR TOO LOW VOLTAGES
SLOWLY increase the voltage one notch at a time for a particular frequency and do stability/testing for few hours
once you have verified that you CPU chip can handle that voltage ONLY then "Set at boot"/Use init.d script
if you dont follow above instruction your device might bootloop
You can either use an APP (like IncrediControl / Kernel Tuner) OR use an init.d script to do the work...
the interface to control voltages is at:
Code:
/sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels
to see current voltage table use:
Code:
[B]cat /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels[/B]
to set voltage for a particular frequency:
Code:
[B]echo 1512000 1150000 > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels[/B]
will set 1512Mhz freq voltage at 1150mV
to reduce voltages for ALL frequencies:
Code:
[B]echo -25000 > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels[/B]
to increase voltages for ALL frequencies:
Code:
[B]echo +25000 > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels[/B]
example init.d script to reduce voltages by 75mV for ALL frequencies:
Code:
[B]#!/system/bin/sh
echo -75000 > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels[/B]
can be saved as /system/etc/init.d/99vdd

Awesome as always

thanks for your work.but i have given up the stock .200 ROM because of 2G data.now i use the PAC rom.

Hi Doom!
Can you make your kernel as boot.img file so I can insert to your pre-rooted Rom? Now I'm unable to use fastboot.
Thanks!

When setting the cpu speed (with setcpu), will it stick to both cores?
This was a problem on a previous kernels.

No Fastcharge?

here is a fix for reboot into recovery...
this now adds compatibility with ROM Manager's Reboot Into Recovery!
cheers!

DooMLoRD

Dual Recovery!
How to use Dual Recoveries (CWM 6.0.2.7 + TWRP 2.5.0.0):
Since many users have their own preference of recoveries, I have included both CWM & TWRP recoveries into my kernel!!
The kernel has inbuilt triggers to enter any recovery. When the kernel is ready during bootup it will indicate by:
showing my bootlogo
pink/amber LED notification lighting up
there is a small vibration
Following are the triggers:
CWM recovery: Keep tapping VOLUME UP button
TWRP recovery: Keep tapping CAMERA button
default recovery is CWM... so a "reboot into recovery" will trigger entry into CWM...

OMG!!!!
Thank your Kernel!!!
It's awesome!!!

Edit: SCREEN SHOT

Flashed and trying it right now
Thanks Doom you're the best mate
It would be nice if you could add more governor
You could add interactive, lagfree and intelidemand ;p
