[ DISCLAIMER ]
I am not to be held liable/responsible if you damage your phone by following / not following this thread.
[ additional info ]
ok, time for some gyan! (by DooMLoRD)
see each cpu/chip is different
each is unique and has different tolerances
slowly keep increasing the frequency
check its stability for 5-10 hrs
check for random reboots
check which one is best suitable for your device
if u start getting reboots/freezes then throttle back and use lower frequencies
remember just because someone else device was able to work at that frequency/voltage doesn't mean that your phone can support/handle that frequency/voltage
I would recommend that u DO NOT use high frequencies for long time! This may damage your device, though the damage is not readily visible!
The high frequencies are just for temporary boost/benchmarks/showoff
You have been warned!

For controlling keypad back-light LED brightness:
Requirement:
Rooted ROM
UC kernel v4
Terminal emulator or use adb shell
Follow these commands in terminal emulator or in adb shell:
Code:
echo 0 > /sys/class/leds/button-backlight/brightness
echo 100 > /sys/class/leds/button-backlight/brightness
It will set your LED brightness to 100.
Note that resetting brightness value to 0 before new value is required.
And also, the brightness value gets reseted when device goes to sleep and woken up. You will needed some script manager to control this in background continuously
OR
use custom scripts like init.qcom.post_boot.sh found in stock ROM's /system/etc folder and add them to init.d folder.
Note1:From UC Kernel v4 and onwards there will be two releases for every type of ROM, one for stable OC upto 1.6GHz with all features and other with OC upto 2GHz.
The reason behind this is that we do not want to become reason for your device's losses. Using CPU frequency at high level (2.0GHz) is very dangerous and it could damage your device.
These damages are not readily visible but on a long run they might affect your device's hardware.
And we don't think that its worth to OC at high frequency levels at the cost of your device.Note2:OC cpu frequency at 2.0 GHz is not stable on STOCK ROM or Andro-ID, atleast thats the case with my device.
But I could atleast use it for a minute or so on MIUI ROM. So you can use MIUI if you want to OC upto 2.0GHz for show off purpose Note3:
I want all of you to test and give me feedback about fix for multi-touch axis inversion. As I have mentioned it is still in experimental stage. And I need to fix some parameters by trial and error. So need your inputs.
Thanx!
Note4:If you do not want to use UC-kernel bootlogo as splash image then remove splash.img file from /splash folder present in update zip before installing UC kernel. If you have already installed UC kernel v5 then your original splash.img is backed up in /sdcard/UCbackup folder. You can restore it using this Revert_splash update zip.

CPU governors:
Helps in efficient ramping up/down of CPU speed as per demand of CPU load.
They differ mostly in the way the ramping speeds are defined. (Dynamic or constant value)
SmartassV2, interactiveX and SavagedZen are built on interactive governor which suits for high CPU performance with reduced battery drain.
SmartassV2 dynamically sets the ramping speed around a set ideal CPU freq (768MHz) in wake mode and minimum ideal CPU freq (248MHz) in sleep mode. It will try to maintain CPU freq around these set ideal limits. So no need to use any other SetCPU profiles.
IOScheduler:
It tries to distribute bandwidth among all processes according to their weights.
Basically, efficient control of work load distribution over various background running application.
BFQ is based on CFQ. (I dont know much details about any of them. And there is no point in providing technical information.)
In my opinion VR is better.
Check yourself which combination suits you perfect based on overall performance (use different benchmark apps) or battery life.

I can not guarantee about stability on your device as every device is different though sharing same manufacturer.
But I have never faced any stability problem on my device except when I had reduced voltage to a greater extent at higher frequencies, which made it to reboot.
To prevent such problems while setting or playing with CPU related tweaks DO NOT SET ON BOOT option in the apps unless you are very sure about the setting.
By not selecting ob boot you will be atleast sure that the settings will be reseted to default after reboot.
On other note, you dont need to overclock always, you can underclock too. Or for that matter undervolt too for better battery life.
Nonetheless using CPU governors and IOSched makes life great for the device.

thanks what i meant by stability is not getting that screen going crazy some times problem,anyway ill try this on my rooted 2.3.4 and keep u posted on the same
I want to get best battery life on this device. i have installed latest kernal,
so pls help what i have to do to get more battery life in detail, because i dont know
much about clocking the device.
so pls help me out.

the crazy screen thing is cause of using high frequencies for long times...
ur devices will work great at 1.2Ghz... even 1.5Ghz is good... but anything above that depends on ur device...

hi DooMLoRD, remember me? in last posts of v02 thread I mentioned my undervolting miracle...
today I tried the performance governer as you suggested, but the phone freezes on startup & restart once SetCPU & IncrediControl gain super user permission, the setting is 1.5GHz @ 0.75v...
for the phone to boot up stably with performance governer @ 1.5GHz it needs 1.125v...
however, if I use on-demand governer (0% powersave bias - meaning it stays @ 1.5GHz 99%~100% of the time, checked with SetCPU), it is fine, I can play 3D games, loop Quadrant benchmark, run more than 30min of SetCPU stress test without a problem... camera works fine....
based on your experience... can the setting be considered stable?..... like.... something in the boot procedure stresses the phone extraordinarily?? lol?
p/s: for 1.6GHz & above, even with on-demand governer, the phone will need significantly more than 0.75v for the clockspeed to even be applied (scale pulling... it freezes there), I forgot how much, but definitely more than 1v
many thanks for your input!!!
My phone can go smoothly on 1.6ghz at -75v with smartassv2 governor.... i tried -100v but its was an unsuccessful try since it hangs and shut off...

1. slide SetCPU max clock speed (but slowly work your way up)...
2. set governer to "performance" (default is on-demand)
3. apply (don't set on boot, yet)
4. in IncrediControl, decrease voltage of the max clock set in SetCPU, initially you may work with larger decrement... like 100mv....
5. apply (don't set on boot also.. just yet)
6. test stability by playing games, record video with camcorder app, run the Stress Test in SetCPU, loop Quadrant benchmark
7. repeat step 4 but decrease decrement
8. revert to previous voltage if current voltage is unstable (write it down, to be applied later with "Set on Boot")
9. repeat step 1
---------- Post added at 06:05 AM ---------- Previous post was at 05:50 AM ----------
I have done a quick test on battery life & temperature for reference...:
Parameters:
- 1.5GHz
- Performance governer
- 30 minutes of GT Racing Motor Academy HD (just left it there... lol... to avoid inconsistency)
- Discharged from freshly charged 100% battery
- Constant ambient temperature & screen brightness
Result:********************Discharge***********Battery Temp.
- 1.3v stock******************-10%***************37 deg. Celsius
- 0.75v undervolted***********- 8%*****************35.8 deg. Celsius

This is not recommended.... keep the decrements VERY small... ideally decrease 25mV at a time...
Also the best stress test is to use multiple runs of LINPACK/BenchmarkPI

sorry sorry, it was a huge mistake, I was about to type 50mv, then I added the "larger decrement" line, I wanted to change to 100mv but typo 500mv instead LOL, sorry......... but you're definitely right, if we have the patience we should just go by -25mv
---------- Post added at 10:09 AM ---------- Previous post was at 09:58 AM ----------
1 more observation (no systematic proof though...)
my phone's signal reception is MUCH STRONGER with the processor undervolted, I'm on full bar most of the time now, whereas previously it would be 2-notch, sometimes none...

-Get in fastboot and flash via [highlight]fastboot flash boot boot.img[/highlight].
-Reboot into recovery.
-Flash the zip via recovery.
-Reboot
[highlight]The same thing applies if you update to a higher version or if you downgrade to a lower version of the kernel.[/highlight]
README!- JB Versions recieve OTA updates over Goo Manager!
-Do a nand backup before testing!
-[highlight]Test[/highlight] versions are for testing, therefore expect bugs and please report them in detail.
-Beware that you use this at your own risk and please provide feedback in order to get it stronger/better/bla bla bla
-The versions of kernel for ICS Sense around here should work on all OFFICIAL ICS 2.31.401.2 RUU based roms, and the official one of course, so if you use a different firmware, make sure you make a backup as there are BIG chances it will not work.
-The versions of kernel for JB will work only on AOSP based ROM's like Cyanogenmod, Paranoid, PAC, AOKP and so on, version 4.2 and up!
-The JB build already have this kernel included as it's the only one right now to support JB for our device, but here you can get the latest changelogs and eventually updates for the kernel if not available otherwise.
-[highlight]ION[/highlight] versions of kernel are for ION versions of ROM's, don't use it if you don't know what that means!
-[highlight]DO NOT USE JB KERNELS ON SENSE/ICS ROMS![/highlight]
-Use SetCPU or CPU Master Free(<<my personal choice) in order to activate OC or other Governors and Schedulers, can be found on market
What i say here is just my opinion for the best freq usage possible:
-Stock: Conservative 245 - 1500 Mhz
-Battery friendly: Conservative 149 - 1200 Mhz
-Balanced: SmartassV2 149 - 1497 Mhz
-Kickass: Ondemand 245 - 1800 Mhz
--Best Graphics score: 1497 Mhz
--Best CPU score: 1800 Mhz (you don't say?)
(1497 Mhz was introduced in LTX since 0.7.6)

Because it's better than stock, don't believe me? Try it!
Q: Will you port this or that kernel for our device?
No, but i can include features, just ask for them
Q: With what Toolchain is this kernel compiled?
This kernel is compiled with official Google toolchain version 4.6.3
Q: Why don't you use this or that toolchain to compile your kernel?
Because there is no difference, check this thread for details.
Fanbar:As now the kernel has a little personality, i decided to make a fanbar

Yes, i got all the compiled modules and flash them with the kernel, the problem is caused by something else, i'm a bit busy with the school right now, i think in know where the problem is , but next week we will have a fully working/faster kernel

Works great with Sense 4.0, thanks mate! Just wondering, after installing setCPU is it only necessary to set mhz to 1804 and nothing else such as governors etc? Anyway, works very fast, good start!
Yes, a so fast battery drain is the only little problem with the kernel...
thanks for this kernal, now my battery consumption in sleep mode is Awesome,,, the day before when i was not using ur kernal it took 30% of battery for one night,,now after flashing this Awesome kernal it consume 3% for whole night... Loved it . Keep going .

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 gokhanmoral!
initially i was trying another implementation for the krait chips based on Faux123's implementation but it wasnt working propely... so I have ported the VDD interace to my kernel from gokhanmoral's commits!
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 Voltage Control) or use an init.d script to do the work...
the interface to control voltages is at:
Code:
/sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
to see current voltage table use:
Code:
[B]cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]
to set voltage for a particular frequency:
Code:
[B]echo 1512000 1200 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]
will set 1512Mhz freq voltage at 1200mV
to reduce voltages for ALL frequencies:
Code:
[B]echo -25 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]
to increase voltages for ALL frequencies:
Code:
[B]echo +25 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]
example init.d script to reduce voltages by 75mV for ALL frequencies:
Code:
[B]#!/system/bin/sh
echo -75 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]
can be saved as /system/etc/init.d/99vdd

hi mate!
glad to see you...
this is just the initial release.... i will be adding lots of features that are hallmark of DooMKernel as and when i get time

No problem. Kernel works/boots fine. Obviously need a lot more testing but knowing you it will be fine.
More governors, touch recovery, UC would be great updates
How about dual boot?

EDIT
There is a clean stock kernel in here
How to use Multi-Recoveries (CWM + TWRP + Philz):
Since many users have their own preference of recoveries, I have included CWM, TWRP & Philz 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 VOLUME DOWN button
Philz recovery: Keep tapping CAMERA button
Alternatively you can now also reboot into any of these selected recoveries using my Xperia Reboot app!
I have updated my Xperia Reboot app to supports multirecovery solution implemented in latest DooMKernel (Feb 1, 2014 onwards) on supported devices!
DooMLoRD said:
please check if u can enter recovery.... (i think i forgot to add that in features)
Click to expand...
Click to collapse
yes i can enter recovery. I didnt do anything with it, but it enters.
I also gave a link to a clean stock recovery in my previous post.
If you can set the lowest cpu speed to 196 and not 384 that would be awesome!!!
Its the best tweak for battery life!!!!
Great work anyway CU soon on the Z community!!!!
How to use init.d scripts
these are small startup scripts which will get executed at bootup
these are supposed to be placed in the folder:
/system/etc/init.d/
IMPORTANT: make sure that the scripts have permissions to execute! else THEY WILL NOT RUN!
Code:
chmod 777 /system/etc/init.d/scriptname
example init.d script to reduce voltages by 75mV for ALL frequencies:
Code:
[B]#!/system/bin/sh
echo -75 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]
can be saved as /system/etc/init.d/99vdd

well trust me there are better ways to save battery... i will be adding all the hacks that i learnt thru my experience for saving battery...

I guess that means undervolting, ¿right?. Thank you so very much.
Kernel level Sound Control
This feature has been ported from Faux123's krait kernel sources. The sources for this feature are covered under GPL and are released along with my kernel sources at my GITHUB repo.
[ WARNING ]
high volume can damage hearing!
DooMLoRD or faux123 are not to be held responsible if this damages ur headphones/speakers/etc
USE THIS AT YOUR OWN RISK!
There are two ways to use this interface.
manual control through sysfs interface
paid app (FauxSound Audio/Sound Control)
How to use the app FauxSound Audio/Sound Control is pretty self explanatory so I will write on how to control using the sysfs interface...
BEFORE DOING ANY ADJUSTMENTS EXIT THE APPS LIKE MUSIC PLAYER/etc!!
The interface to control the sound output is located at:
Code:
[B]/sys/kernel/sound_control[/B]
it has 4 control interfaces:
Camera MIC
Code:
/sys/kernel/sound_control/gpl_cam_mic_gain
Headphone
Code:
/sys/kernel/sound_control/gpl_headphone_gain
MIC
Code:
/sys/kernel/sound_control/gpl_mic_gain
Internal Speaker
Code:
/sys/kernel/sound_control/gpl_speaker_gain
each supports gain levels from 20 (-20) to 50 (+10), base is 40 (0)
(the number in the brackets correspond to the numbers displayed in the app)
say if u want to boost headphone output (both left and right channels) then use the following command:
Code:
echo "46 46" > /sys/kernel/sound_control/gpl_headphone_gain
u can also individually increase/decrease the gain for each right and left channel
similarly other interfaces can be controlled
TIP:
do not jump to maximum values as sometimes the headphones/speakers might start distorting the audio... slowly increase and do testing for the levels which suit you!
not all accessories will work well with boosted audio output
e.g.: on my Sony MDR-XB300 headphones i start getting distorted audio beyond 48 (+8)
regards,
DooMLoRD
Nice flashing now :laugh:
backup and restore works. Overclocked on 1,728 GHz . No problem so far
Can't download, file is down or maybe the server is overloaded.
Tnaks Doomlord for bringing your Kernel to our XT
Edit: Seems to be the server Sorry for the annoyance
i have read a lot about the doomkernel,
but no phone which supported him.
now i can test it by myself,
thanks :good:
just a little question,
can you change the cwm background from grey into black?
*edit*
when i try to overclock the cpu at 1890mhz,
crashes (reboots) the phone.
tried to overclock with no-frills,
trinity kernel toolbox &
i've done it slowly from 1512mhz step by step to 1890mhz.

Ahh so true....
I managed to use the phone normally on 1.89 but just now I had an incoming call and the phone hung from being deep sleep, time to throttle back...
Re: [KERNEL][T] DooMKernel {JB}(v01)[Dt: 01/03]
In my opinion, this device is fast enough on stock frequencies. What we need is better battery life with stock performance.
With this kernel, my phone can finally go into deep sleep mode!
Thanks doom, keep up the good work

[B][04-29-2013][/B] initial release
Additional stuff:
GPU OC more than 520MHz:
For daily use, i set the max GPU rate to 520MHz. This should be enough.
But if you think, you need more heat to cook something for example, you can go up to 600MHz. Therefore you need to set a new max GPU clock limit. You do this using the following commands:
Code:
echo '<GPU_clock>' >/sys/devices/system/cpu/cpu0/cpufreq/gpu_oc
with <GPU_clock> being your new desired max clock rate
Setting LP max rate:
You have now the ability to set the max speed of the low power core (5th core). You can do this using the following command:
Code:
echo '<LP_clock>' >/sys/devices/system/cpu/cpu0/cpufreq/cpu_lp_max
with <LP_clock> being your new desired max clock rate
Changing the voltage table:
You have the ability to change the voltages for the processor from now on. But just because you can, doesn't mean you should. Changing voltages is dangerous! In the worst case, you can burn your processor!
I am not at all responsible for damage, caused my my kernel/your settings!
You can find the interfaces here:
Code:
/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table <--- CPU
/sys/devices/system/cpu/cpu0/cpufreq/avp_UV_mV_table <--- GPU
/sys/devices/system/cpu/cpu0/cpufreq/emc_UV_mV_table <--- RAM
/sys/devices/system/cpu/cpu0/cpufreq/lp_UV_mV_table <--- LP core
For using @arararagi's hardware customizations, i'd suggest you to use his toolbox from this thread
Stock builds of Werewolf JB
Hi all.
I'll be maintaining WerewolfJB kernel for stock. The links will be listed on this post. I may also upload experimental kernels.
All credits go to @laufersteppenwolf for his excellent kernel.
For now, the link for WerewolfJB v005 stock is this: https://www.box.com/s/okea8s7pdqcgf5soppbi
And for WerewolfJB v005 CM (with increased voltages and new modules for mobile data): https://www.box.com/s/4d3vxivlcu9ebsku6r4f
Flash it via CWM/TWRP.
Note: Both stock AND CM versions have increased voltage for the 1.7GHz step to 1300mV because of reported instability. Be careful in undervolting since the voltage table is slightly imbalanced, so perhaps -75mV can work for some frequencies but not for others. Furthermore, I removed quite a lot of wakelock references in baseband_xmm_power but forgot to revert them back to the "fix", so if you have any baseband instability please drop me a PM. Also please do report battery life performance, along with a screenshot of your wakelocks and ideally a dmesg. Thanks.
==============================
Experimental versions (for STOCK):
None for now.
Woohoo thanks!! Goodies for us

I would have liked to release the ROM tonight, too.... but my lappy somehow didn't agree with me
Please test and report back. Also about gaming performance.
Is to flash the Kernel with Fastboot the only way ?
Our can I flash it with Terminal Emulator?

What about battery life?
On official CM when I use 3G Internet, battery drain is very, very fast.

this is a great news, another custom kernel :beer:
but I'm still with zaiben rom (base on stock rom) cause for me cm 10.1 rom still not ready for my daily use. I hope you will build for stock rom too
surely I will try your kernel when I'm ready to move to cm official or when you release you rom

This kernel seems good so far - feels smoother and more consistently buttery. I'll have a look for bugs - I don't know about the governors, though.

For development sake can you verify if gesture typing works properly? Then we'll know if the kernel broke it or the test rom

Happy user? How about small cup of coffee for me? Click Here.Flash Superuser_CWM only if root is lost. I will be implementing sure-root method in kernel soon.
Install Performance Control to set CPU OC/UV, schedulers, governors.
Install STweaks only if it is not auto-installed on flashing kernel. It gives control over GPU and many other tweaks.
Topic explaining all basic Governors & I/O Schedulers: Click Here
Governor we HIGHLY RECOMMEND to use as default:
Hyper -
The Hyper (formerly known as kenobi) is an aggressive smart and smooth, optimized for SMDK4210 board getweakt and, based on the Ondemand, which was getweakt of Arighi and was equipped with several features of Ondemandx suspend imoseyon. (Added by sysfs, the settings suspend_freq and suspend Imoseyon's code) is the behavior of the hyper Ondemand if he is in action, very similar. He also has the Arighi's fast_start deep_sleep and detection features. In addition, the maximum frequency is in suspend mode 500Mhz
IO Scheduler we HIGHLY RECOMMEND to use as default:
ROW -
ROW is Read Over Right. As name suggests it services more READ requests than WRITE taking care that WRITE requests don't starve.
It is most suitable because Android handhelds unlike desktop hardly uses multi-threading and a user seeks more of responsiveness than giving more input.
zzmoove is ported governor (by me) from SGS3. Read about it HERE.
My Recommendations:
Recommended Governors: HYPER > SmartAssv2 > LulzActiveq > Abyssplug > Zzmoove > Pegausq > Others
Recommended Schedulers: ROW > ZEN > CFQ > SIO > NOOP > Others
In case you have SOD (Sleep of death), please check minimum frequency. It should be greater than 100 MHz.
Recommended 200 MHz.
NXTW-Kernel Changelog:
v1.0.2:
STweaks App (which gets auto installed on boot) featuring
-GPU Overclock Control (100MHz to 520MHz)

F.A.Q.:
Q. I am getting FC / Performance control not working. What is the solution ?
A. Reboot in recovery. Wipe cache and dalvik cache.
Q. I am getting sleep of death. What do I check ?
A. Adjust minimum frequency to 200 MHz and not lower.
Q. Which is best governor and IO Scheduler?
A. All of us have different choices. There is no thing like best governor or IO Scheduler.
You need to set your personal favorite. I have posted my recommendation in above post.
Q. It takes long time to boot. What is wrong ?
A. Nothing is wrong. Let NXTW optimize your apps and database.
Q. How to insert a module that's available in /system/lib/modules?
A. Safe to be root. In terminal or adb
su
insmod /lib/modules/<module_name.ko>
You can request your required module, if you want.
Q. How to know which modules are pre-loaded by kernel?
A. Terminal or adb:
lsmod
Q. I want to help dev debug an issue providing a kmsg. How to?
A. After the problem (random reboot/freeze/lockup), do not pull out battery to recover. Just long press power button so that device can reboot. Then connect device to PC, (provided you have setup adb), type
adb pull /proc/last_kmsg
Save the file as .txt and post in the thread along with description of the problem and possible way to reproduce it.
If you can't use adb from pc, just copy last_kmsg file from /proc directory to internal sd, copy it to your PC and post in the thread.

Recovery is same as COH Kernel. I actually got from him on PM.
I am JonROM, after 1-2 min it got stable.
This (Initial jitter) is expected behavior since merges are not complete.
I know your good kernel neobuddy, i will wait for another testers, sometimes freezes can arrived, but unable to boot in recovery mode. Maybe a bad flash ....

Agreed. Sweet Rom V7 slows down to almost freeze.
Tried to reboot recovery but black screen after N7000 Logo.
No normal reboot, no recovery.
Odin-> Philz-Kernel. Reboot ok.
Back to c.o.h.-Kernel.
Neobuddy, remove your download link before noobs flash this and crying after you.

BRIEF EXPLANATION ABOUT KERNEL FEATURES
UKSM
UKSM is about de-duplication of data in system memory rather than being another de-duplicating file-system. This improves RAM usage.
Dynamic Sync Control
The dynamic sync control interface uses Android kernel's unique early suspend / late resume interface. While screen is on, file sync is disabled. When screen is off, a file sync is called to flush all outstanding writes and restore file sync operation as normal.
Frandom
Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux' built-in /dev/urandom. It uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.
CPU Boost driver
When certain bursty and important events take place, it might take a while for the current cpufreq governor to notice the new load and react to it. That would result in poor user experience. To alleviate this, the cpu-boost driver boosts the frequency of a CPU for a short duration to maintain good user experience while the governor catches up.
FAQ
On which ROM can I install nebula?
- nebula can be used on any AOSP kitkat 4.4+ based ROM. (Carbon, SlimKat, CM11)
What is the best and most stable configuration for nebula?
- Configuration depends from user to user. Still, the most stable configuration according to me and that I use is below. It might differ for you.
- Governor: SmartassV2
- Max. freq: 1.2 Ghz (OCing doesn't really have an increased and noticeable performance, rather it heats the processor and wastes battery for a marginal gain in performance as well as creates instability - random reboots etc. Google more about OC.) (Read the description on this commit.)
- I/O Scheduler - SIO
- Enable UKSM (from Performance Control app)
- Enable Dynamic FSync (from Performance Control app)
- I'll update this configuration as more tweaks are added to nebula
I get random reboots, what should I do?
- I am working on the kernel for myself and the kernel is quite stable for me. Still, if you face reboots see below:
- Make sure you followed the installation instruction written in Post #1.
- Make sure you "Fix permissions".
- OCing will always cause instability. Try reducing the max frequency to 1.2 Ghz
- It is quite possible that you don't know how to use a custom kernel. Not everything needs to be set at HIGHEST. Just because an "option" is there doesn't mean you have to select it. Try changing the configuration that meets your needs and satisfies you. If you set up the kernel properly, it would stop giving you random reboots.
- The only way to get things fixed is to provide logs. I cannot fix that I cannot see. Google, how to take logs to find and solve kernel issues. (kmsg/last_kmsg)
- Tell me a way in which I can reproduce the issue on my phone.
Does hotplugging work well with zzmove governor? I remember trying hotplug on s2vep and it freezed almost everytime while deep-sleeping.

Same issue on baffin too. That's why I have removed zzmoove from the kernel.
hmm... xenon92... already k2wl has made a custom kernel with O.C till 1.8GHz so why have you the max @ 1.6GHz ?

Read the description in this commit - Link
There has already been a discussion on CM11 thread about how much does it really benefit by OCing at higher frequencies. Refer to that thread's discussion for more info.
In short - OCing at too high frequency heats up the CPU (obviously) and doesn't necessarily increase performance.
Even though I have added OC till 1.6 Ghz, but even I don't use that setting. 1.2 Ghz is fine for me.
Another kernel for AOSP rom.....:laugh::laugh::good::good::good::good:
Installed the kernel in carbon ROM and is working fine....:good::good:
ll update more on the battery stat later...
any FC's anybody facing?....anything at all..during call or anything??..just asking..would have tested myself but my net is limited right now till tomorrow......so can't ..will surely tomorrow onwards download evry single one (as m xenon work fan lets say )...but wont risk using mbs if it got any bugs...

It's actually 1797 MHz, so let's say it's only 3MHz shy from 1.8 GHz
This kernel looks promising, I will download, install, and use it for a few days

Been in interactive with 1200 max for an hour now...
Dint tried overclock though...:fingers-crossed:
I need a lil battery life guys my service provider doesn't have 3g for now some TRAI issues and i stay away frm hme most of the time so using 2g and the screentime i get max is 3 hrs 30 mins wid evolution kernel processor=conservative,I/O=sio or sio plus and today i reverted back to cm's stock kernel and have flashed the latest build my biggest issue is when my battery drops down to 30% it starts draining drastically say like for 2 mins from 30 to 24% any help would be definitely appreciated have made calibrations until now again calibrating tonight and will test after that nebula for sure because only name i knew for best custom roms was and is XENON92!:thumbup:

i set the cpu at 1.5 but when i restart the phone it rest to 1.2 i also check on set on reboot and try on uncheck on reboot

If the system did a forced reboot to avoid further CPU instability, the options will revert back to default... correct me if I'm wrong.
pawitp also said in the CM11 thread, that the options dont instantly set on system boot. You may have to wait 1 minute and check back.

thanx mate ,,,, i read it also but forget
thanx again
@xenon92
Nice work. Just checked the CM11 thread. The latest update upgrades their generic kernel to 3.0.101 . Any plans of updating yours?:laugh::good:
