Hello Guys, I would like to present you my first SGY kernel which I have compiled from source. This is only for Stock or Stock based ROMs.
Features :
1) Loads of governors like userspace,ondemand,powerspace,conservative etc. so that users will not get biased towards only one configuration
2) I/O schedulers like noop and cfq with cfq as a default scheduler
3) Max frquency 832 Mhz and min frequency 312 which I found the best in terms of battery and performance because Overclocking decreases the life of Phone.
I am currently lookoing forward to add Extra I/O Schedulers although cfq is best out there with Conservative governors in my opinion. CPU underclocking will be in my roadmap as well. I hope you guys will appreciate me.
Steps for Installing/Flashing :
1) First reboot into recovery and flash any CWM recovery(Note: don't flash it through stock recovery directly)
2) Go to mounts/Storage and mount everything system,cache,sd-card
3) Now flash the Zip I have provided
4) Now Wipe cache partition from Main menu
5) from Advanced option-> wipe dalvik cache and reboot
I have tested it myself.Please report in case you guys run into any issues.

I will add amarullz a2Sd support and integrated CWM recovery very soon. I still need to check why deep sleep isn't working. Thanks for feedback.

Hello,
According to XDA Rule on GPL and Apache Compilence
For kernel developers: You must provide FULL source code, not just the edits you made (reference here). Your source code must also be up-to-date with any binary releases. If in doubt, update your github first, then release the binary, NOT the other way round.

the stuff you have provided on your github is only the kernel.
You have to upload the whole source code you've used while compiling this kernel.Do it ASAP if you didnt knew it.Or your thread will be closed soon.
Take this as a suggestion :good:
Regards.

Thanks for your suggestion brother. This is my first contribution,that's why i wasn't aware of it. Do you mean the Samsung open source update which i have used to compile it ?
can you guide me how exactly i need to update it ?
deep sleep is present in stock kernel too.
only states files is not enabled/present.
if cpu spy is displaying freq. usage and deepsleep is notshowing up then there is some problem.
else by default its enabled in stock kernel.

Thanks, I will upload it on my github in the evening.
Well anybody tried compiling the kernel on Ubuntu 14.04? Gonna try it today! xD

check again.
its says- states file not found.
kernel is not compatible with that app cz freq. states file is disabled by default.
but deepsleep is enabled in kernel.
also the kernel u build is having old source.
latest kernel from samsung in update like dxmj is best n having many changes.
just add init.d support in it and compare the battry life with ur kernel.
and that stock one is far more stable than urs.
no offense
but untill and unless u add some more features in it, stock kernel will still be my preferred choice.
add more featrs into it to make it better than stock one.

You serious?
That's good.Gonna try soon!
Good one... :good:
the problem is it seems to have update2 source.... :-/
can run newer firmwares (ddmd,dxmj, etc).
Looking forward to this one. Please use update3 in the next one. Best of luck
P.S. As @Nitzz Said, Deep sleep is pre-included. if u have used the defconfig command, it is included in the kernel. try adding cpu_stats file...

Hello guys
I'm a new user and I have a big problem with this ROM
I've tried a lot of ROM and imho this ROM is the best!
The only problem is the heavy battery drain .___. I tried everything I found in this forum, but the problem still persists and I don't know how to resolve this problem..
can you help me?
Sorry for my english..
Install No frills cpu control app and enable deep sleep option in settings and try...:laugh:

sorry for my english
use greenify..but still I believe battery drainage is higher in minicm9 as compared to sense roms.
You may have faced this bug
-Not Able to Lock Frequencies
-Not able to Change Governor

Does this fix work for stock MIUI 6 kernel??
Awesome! I can't believe no one comments on this. This fixed my issue with miui7(completely stock btw) that for some reason didn't use lower frequencies than 960mhz. Just used no frills cpu control and was able to fix the lower frequency at 200mhz and changed governor! Checked with cpu spy and saw its now using the lower frequencies. Thanks a lot
@Kiran Anto does your RazorReborn kernel also need this patch? or were you able to incorporate this into it? Btw thanks for the good work!!
How can i undo this? the setting messing up with my phone.. works the opposite~

so i was on cos12 das2k1 build and i thought of flashing lord boeffela kernel ,, but would it really improve battery or perfomance as much as to make a noticeable difference ? thanks

It can make noticeable difference only if you customize the kernel parameters using the Boeffla App
You can simply load profiles(created by some user by changing kernel parameters) or you can configure each parameter by yourself from here

hey i just flashed the boeffla kernel on stock rom and its running pretty good !
although UNDER MISCELLANEOUS 1 ,, first option SYSTEM TWEAKS
can anyone tell me what does that option do exactly and to which do i set to it ?
there are 3 options : Boeffla tweaks,, speedmod tweaks and Mattiadj tweaks ! can someone help me out with this ?
If you have the kernel and app installed you would have been to Lord Boeffla's download page. All the info and links are provided. The man is nothing short of thorough in what he does.
