Installation:
1. Download kernel
2. Reboot to recovery
3. Backup
*if you come from faux or tbalden please reflash your rom, you don''t need a wipe. They have some trickery with their own hotplugs so they have reomved mpdecision, so without reflashing your phone will be stuck on quad core*
4. Flash kernel
5. Reboot
*Please let it sit for ~10 mins before judging as it will need to settle down. Do not judge battery life unless you've run it through at least 3+ cycles after flashing*

DISCLAIMERS:
1) Excessive under/overvolting can cause damage to the internal parts of your phone. It can cause the phone's lifespan to deteriorate quickly so make sure you know boundaries
2) If you OC'ed/OV'ed/UV'ed and now are in a boot loop or your phone is slow, or acting weird or just died - it means your phone does not like the changes. Voltage control is for those who know what the risks are, know what they are doing and know how to fix it. Perhaps when you change these, test them for an hour or so before setting on boot
3) Any changes to the phone, including flashing the kernel itself is done at your own risk.
4) Every phone is differentt
5) Please DO NOT use any task killers (or additional init.d scripts), they DO NOT improve performance/battery. The kernel is designed to be used with stock settings: my settings and anything else can cause problems

Depends what you want to do most of the time you can use trickster. But, for frequencies you'll need to use the script to cap it since o have pnpmgr enabled
Pnpmgr is HTC power and performance manager and it is responsible for boosting CPU and gou when needed. So its enabled to eliminate any stutter

I just want to set governors and clock speeds, as well as modify screen wake settings and such. Is that possible without the script?

Click to collapse
Since you say clock speeds, you will need the script
However I am a strong believer in keeping the clock speeds stock. It has great battery already (I always last the day on one charge) and lowering the max freq say to 1.4GHz will extract a bit moer battery, maybe you will end up on 20% instead of 12% at the end of the day. If I want to underclock I will use the poewr saver option for CPU (assuming it works for you on this device, since some roms it doesn't work on) I know viperone has this working
imo, try without the underclocking and if you need it you will need to use teh script. its easy, I can walk you through it if you'd like

Any reasons to not use SMARTMAX over Ondemand?
Also I am not familiar with FIOS. I always used ROW but looking for best battery life.
Quick question for the kernel guru, I noticed the kernel mentions how it increases the gpu bandwidth, the question I'm wondering if you can elaborate what it is? I googled the feature and I only came up with hits from you!
Two words...luvvv it!

personally, i dont notice a lot of difference between different schedulers, but we had a discussion about it in the gsm thread here . as for the governors, i prefer ondemand, because (for me) it has the best combination of battery and performance, but some prefer smartmax or preservative more. you can also find some infos about that in the gps thread

DONATIONS:
I will not be accepting donations of any kind for this kernel. Seriously, don't. I didn't write the majority of this kernel's features. All I did was compile it into one single, streamlined kernel. Instead, donate your money to the people given credit above. I don't need your money (I'm in high school) and I don't want it either

FAQ:
Will you add ___________ feature from ___________ kernel?
Ask nicely in the thread if it has not already been asked for and I'll determine what to do from there.
Kanging is bad, you butt!
Don't use this kernel if you don't want to. All credit both here and on github was given to their respective authors, and I don't claim to be making this kernel for my benefit.
OMG HALP my WiFi keeps dropping zomg why???
Attach a logcat of it entering deep sleep and dropping a connection.
My phone is bootlooping, WTF man?
Flash the reset kernel before flashing this kernel, because some kernels use non-standard ramdisks which are incompatible bigtime with this kernel.
How do I control this kernel?
Franco's kernel control application has 100% compatibility with this kernel, as this kernel is based off his kernel. Faux's kernel control application has approximately 70% compatibility or so, as things such as intellidemand-specific parameters (Snake Charmer, Eco Mode, etc) are not yet available. Also, although color control works, gamma control does not work in faux's app. I've heard that TricksterMOD provides a good balance of tweaks available and that most things can be controlled from that app, but I have not tried it myself.

@rohan32 Thanks for the great kernel dude! It's got all of the features I look for
Do you know if this kernel includes Franco's version of the Simple GPU governor (I'm not even sure if he's released this yet), or the plain Faux version?
Thank you very much for taking the time to do this!

Nice kernel. Running very good so far.
But a general question after having flashed hundreds of kernels in my life:
How can it be that different based kernels are running better or worse? To be precise, for me all kernels based on faux's are running bad. Choppy animations and lag...Based on franco they run so well for me...I don't get it!
Hello sir, can i ask what version of Franco's kernel this is based off?

I hardly think you should criticise someone's hard work. Frankly both are great developers and both make my phone fly. Its only a matter of personal opinion.
Will test and report this kernel soon. Seems pretty hardcore.

It should as the installer only injects the zImage of the kernel, but the ramdisk stays the same. I haven't tried it, however.

Really can depend on any number of things, like each phone's hardware is different, and the fact that there are many different commits that constitute each kernel. Your phone may react differently to various commits than other people's devices.
In this thread you may find my customized kernel 3.0.x for JB 4.2.2 rom (CM10.1 and derivatives).
I hope it will be useful, and ensures better performance and battery life.

It is just a rename, no changes yet...as seen from his GitHub...expect if he did not update it before releasing as per real world law...
Hi, at first I wanted to congratulate you on releasing your kernel, but you disappointed me again:
Misconception:
-- Init.d support [all AOSP kernel supports this, it is a feature in stock but not AOSP, already told you before]
-- Add -O3 optimization for modules [not done anywhere]
Below are the features from Slim kernel:
-- Optimized AES and SHA1 routines for ARM cpu architecture
-- Optimized ARM RWSEM (read/write semaphore) algorithm
-- Optimized asynchronous I/O latency on solid state disks
-- Optimized string and memcopy libs
-- Voku and Dorimanx Tweak for LowMemoryKiller
-- Disable Gentle Fair Sleep for better perfomance
-- Asynchronous I/O latency
-- Lower swappiness 600----->45 [it's 60]
What you did:
Compiled with Linaro 4.7.4
optimized LPDDR RAM timings (~10% throughput increase)
add Frandom v2
Added NEON compilation flag
mm: Dynamic management of dirty page writebacks
Battery Life eXtender (BLX)
add New Governor From Nexus Kernel
Added optimized CRC32 algorithm
So this kernel is very based on Slim kernel...and why didn't you state it and credit @mnazim properly?
And, removal of sources of the old Nexus kernel means you cannot share it in public anymore...didn't you learn anything since the Semaphore kernel incident?

It is just a rename, no changes yet...as seen from his GitHub...expect if he did not update it before releasing as per real world law...
Hi, at first I wanted to congratulate you on releasing your kernel, but you disappointed me again:
Misconception:
-- Init.d support [all AOSP kernel supports this, it is a feature in stock but not AOSP, already told you before]
-- Add -O3 optimization for modules [not done anywhere]
Below are the features from Slim kernel:
-- Optimized AES and SHA1 routines for ARM cpu architecture
-- Optimized ARM RWSEM (read/write semaphore) algorithm
-- Optimized asynchronous I/O latency on solid state disks
-- Optimized string and memcopy libs
-- Voku and Dorimanx Tweak for LowMemoryKiller
-- Disable Gentle Fair Sleep for better perfomance
-- Asynchronous I/O latency
-- Lower swappiness 600----->45 [it's 60]

Real law means intellectual property right? Well then i have to state my opinions. One, this kernel is not earning any money or use ad like someone. Second, original creator of such code is also not earning money frm his creation so i can only see a moral intellectual property rights which is to demand this thread to credits those people properly. Third intellectual property rights is not so easy to be claim as you think. There are few principle such as improvising or this op did expanded his labour work n time to compile and the extent of his own work to actually produce this piece of kernel.

Nope...real law as in GPL...it is different from what you are saying...I did not say he broke it just yet (athough he did before), I was just saying he has to follow GPL, that's all...faux123 got penalised a few times for not adhering to GPL...
Even there is no such law (which is not the case), can't an innocent "user" like me know what's being modified and done to my device? :angel:

On your own risk, but what's the point of sharing if people do not know what's going on?
And what is the point with such restriction that will reduce development in xda which was meant to promote n encourage people to develop and introduce ways to put our device to better use? Op since last time in s plus thread got good reputation in his works and even now in s2. I hope this wil not stop people from giving their time n energy working on their works.

I do not care if the op has a good reputation. The op isn't going to buy me a new device if I brick mine due to this kernel now would he? A kernel is far more important to how a device functions rather than a ROM. If there's little to no CORRECT information given, how would I know what I'm flashing is safe. You may tell me to just skip this and not flash this. But what about other people who sees the stuff in the op but isn't getting what they came for. Complying to GPL is a lot more than what you may think it is. It also helps learning and experienced people know exactly what they're getting.

franco.Kernel +
*Discontinued*
These are my personal franco.Kernel builds with some modifications, explained below.
Things I want to achieve with this mod:
- more battery life
- same more performance as stock
- smooth ui / games
- less heat
Highlights:
Advanced Dynamic Scaling:
The interactive governor will now use different values for up_threshold, timer_rate and min_sample_time for every cpu_core and gpu_idle state. If the gpu is busy, the governor will use values for more performance and if it is idle, it will use conservative settings.
The current values, feel free to suggest other.
Code:
/* up_threshold, timer_rate, min_sample_time */
static unsigned int interactive_val[GPU_STATE][ACTIVE_CORES][TUNABLES] =
{{
/* gpu idle */
{100, 40000, 10000},
{100, 40000, 20000},
{100, 40000, 30000},
{100, 40000, 40000}
},{
/* gpu busy */
{90, 20000, 40000},
{90, 20000, 40000},
{95, 20000, 60000},
{95, 20000, 80000}
}};
Dynamic Touchboost:
The touch boost is only active if something is rendered on the screen, that means the boost will pause as long as there is no movement, but it will resume when it is actually necessary. It will double the actual cpu load and calculate the frequency, the maximum is input_boost_freq. This aggressive calculation offers a smooth ui, but it can also save battery, because you will often don't need input_boost_freq when the screen is touched.
New Hotplug Solution:
Instead of linking core0 to core2 and core1 to core3, all cores a controlled separately. This should prevent an excessive hopping up and downwards. The load is calculated with all active cores to get the performance we actually need.
After some time (if 2 core touchboost is active) and not touching the screen, only 1 core will stay online to save a bit more battery.
It will use different up and down thresholds for each gpu_idle and cpu core state.
Code:
/* down threshold, up threshold */
static unsigned int hotplug_val[GPU_STATE][ACTIVE_CORES][TUNABLES] =
{{
/* gpu idle */
{0, 70},
{40, 80},
{50, 90},
{60, 100}
},{
/* gpu busy */
{0, 60},
{30, 60},
{30, 65},
{40, 100}
}};
https://github.com/reborn90/mako/blob/nightlies-4.3/arch/arm/kernel/mako_hotplug.c
Smooth thermal throttling:
When the temperature hits the threshold, the frequencies won't be limited immediately but scaled down step by step to prevent lagspikes from jumping between 1,5 and 1GHz (if the current temperature allows it). This mod is absolutely not made for benchmarks because my solution is as agressive as the original one. There are other good kernels to melt your device.
https://github.com/reborn90/mako/blob/nightlies-4.3/drivers/thermal/msm_thermal.c
Recommended settings (default):
thermal threshold: 65
Hotplug:
high load: 60
low load: 30
cores on touch: 2
Interactive governor:
dynamic_scaling: true
input_boost_freq: 1134MHz
input_boost_freq_duration: 1500
Interactive gpu governor:
up_threshold: 60
down_threshold: 25
Per app settings tipp:
Set input_boost_freq to the lowest frequency for games.

Eh, since my CPU binning is at nominal only, I dare not UV more than 100 though.
And afaik, UV excessively does not actually help save battery, instead it uses more power. Somebody made a test, its somewhere in XDA.
I can reach 7 hour SOT in 4.2.2, I just lost that screenshot somewhere, in 4.3 I have yet to find it(5 hour SOT is not hard).
Shows 162. Undervolting your device reduces the power the processor receives to only what it needs to run. If you don't suffer any I'll effects in performance I don't see how u would lose battery. However, I'm a try it and see how it works kinda guy.

It keeps heat down, but might result in higher battery consumption in some cases.
Vindicator Kernel
Intro:
This is the first Samsung kernel I've ever developed. I just started developing on android a few months ago so I'm brand new to this. I don't really consider myself a developer, I'm just good at figuring things out, all credit goes to the real hard workers coming up with original ideas like Franco, Imoseyon, Ktoonsez, etc. I hope you like it and I won't be offended if you hate it. All ideas are welcome and I'll try to help as best I can. If you wish to use this kernel in a rom , feel free! Although I would love it if you let me know just for my own curiosity.
Goal:Keep kernel as lean as possible while adding certain, desirable features, upstreaming source, and optimizing for maximum performance and battery life. The default settings should be optimal for a balance of battery and performance without a need to tweak.
Disclaimer:If your phone blows up, its not my fault. If your phone somehow gains perpetual battery life, I'll take full responsibility.

FAQ's
1. What Is VControl And How Do I Use It?:
VControl is a kernel tweaking "app" built into the ramdisk. It is accessed via terminal emulator. To use it simply download terminal emulator, Type "su" without quotes and hit enter. Grant terminal emulator super user permission and then type "VControl" without quotes. Please note that it is case sensitive. This will bring up a text menu and you navigate by simply entering the option number you want and hitting enter. It is currently a WIP. FSync control and Power Efficient Workqueues don't currently set on boot properly More will be added to VControl over time.
2. You Broke My Phone! Fix It!:
It will be quite hard for me to figure out what is going on if you don't provide details and a log of what happened. To get a log use any file manager with root support and navigate to proc/last_kmsg.
3. What Kernel Tweaking App Should I Use?:
To Tweak the kernel, currently the only app that works well is KTweaker. To get KTweaker simply flash ktoonsez kernel which will install the app, then flash this. You will have the app unless you wipe data. You can also use VControl for a limited number of things
4. What Do Power Efficient Workqueues Do?:
Typically when a task is created, it is bound to the cpu it was created on. This is great for performance due to maintaining cache locality. However its not the best for battery life. Power efficient workqueues attempts to schedule tasks on already awake cpus. A quick note about awake and sleeping cpus. A sleeping cpu doesnt mean the cpu is turned off or not hotplugged, nor does this mean it has to be deep sleeping. A core can be online and still be sleeping which means it uses very little power. This is why we are able to run with all 8 cores on all the time. Most of the time the majority of the cpus are sleeping. With power efficient workqueues, jobs will attempt to schedule on awake cpus which means we dont have to wake up the cpus that are sleeping already. This means we lose cache locality so we suffer a small (very small) performance hit but we potentially save noticeable amounts of battery. Enable for battery, disable if you plan on benchmarking or just want the extra power. They are off by default.
5. What Is Strict Aliasing And Why Should I Care?:
One of the big things Linaro does with improving Android's performance is fixing violations of what's known as "the strict aliasing rule." A pointer is said to alias another pointer when they both refer to the same location of memory. This is OK and not an uncommon thing to do. The strict aliasing rule is that pointers of different types should never refer to the same location of memory (aka alias each other). Strict aliasing allows a compiler to make some assumptions when compiling and optimizing code that it otherwise couldn't. It's actually one of the biggest optimizations you can do and it is fairly hard to add which is why most people don't. Here's a nice read up on it http://cellperformance.beyond3d.com/articles/2006/06/understanding-strict-aliasing.html#benefits
6. What Does Moto QuickWakeup Do?:
QuickWakeup is a driver developed by motorola which increases battery life when the screen is off. It allows for only the modules which need to be woken up during sleep to wake up, thus conserving power.
7. What does Small CPU Task Packing Mean?:
Task packing Is a process done by the scheduler. What it tries to do is pack all tasks onto as few cores as possible. In this case, it only packs tasks for the low power(small) cores as we want to maintain maximum performance and spread the load out on the bigger cores. The advantage of packing tasks is that if we envision a scenario where there is a 40% load and that FETs spread out across the 4 small CPUs at 10% load each all 4 small CPUs are awake and running at a low frequency. With task packing all 40% would be shoved onto 1 core and the other 3 would sleep. This provides energy savings. However there becomes a point where the frequency required to process the extra tasks becomes high enough that it would use less power to run two cores at half the speed rather than 1 core at a very high speed. In this scenario the scheduler will automatically let tasks spill over onto adjacent CPUs in order to maximize power efficiency. One down side to this is a small performance hit due to having to pull the other cores out of a sleep state in the event of needing immediate power. However I would guess most people couldn't notice a difference.
More will be added as they come up and I think of them.

Happy to hear that sir! You are the only other person to have tried it so far so that's good news. BTW. Idk what AVS# you are but I'm an 11 and I have stably undervolted by 75 for the A53 cores and 50 for the A57s. Maybe that will help someone.

I like your ideology behind this kernel. Totally reminds me of imosyen nice to see another dev here! I tend to keep my volts as is. I always have problems
Would also like to say that this kernel is best one for my phone so far! Haven't noticed anything but stability. Thanks

Haha. My first kernel I ever made was for nexus 6 based on his lean kernel so that's what I learned on. In fact I believe I've got almost all the stuff removed that he has removed back on nexus 6 plus even more that I've found. I'm a firm believer that less is very often more. Expect more trimming down in the following builds.

Well now I know I'll be in good hands ?
I've been following him since the note 3 days.
Can't wait to see where you take this project!

Downloading and testing now. Not really related, but I was wondering if power save overrides cpu clock/gov/anything else? The reason I ask, is that I typically underclock or undervolt a bit to save some battery but keep in normal high performance state with PS off. But if PS mode does this anyway, I shouldn't bother should I?
Wow, that 3rd post (FAQs) was super-informative!

Edit: Everything seems to be running perfectly fine so far. Charging up so I can see how the battery life is. I'm currently on OZOP's ROM.

To be honest I dont know specifically what power save mode does. I've only had the phone for like 6 days. Ik ps limits frame rate and stuff like that so You will save additional power beyond Running in normal mode, but I'm not sure how it affects cores and frequencies currently. This phone is a whole different beast than my nexus 6...I would like to add more, lower frequency steps to save more power. Glad to hear you are liking it so far though! And I plan on adding a configuration guide of sorts in my 4th post with more detail on the controls available . I also plan on getting synapse working properly as that will enable significantly easier kernel tweaking.

Thank you! Your build script and zip file were a massive help to me. This is completely different from building for a nexus. And I'm not too worried yet the device is little over a month old. I'm hopeful we will see more development start to come. I tried to use your new script setup but I couldn't get it booting for some reason. I'll have to revisit it. I'm sure I didn't something wrong. I'm a Noob.

I know there's a unified method that ktoonz and a few others use/developed, reach out to him for assistance! However, just out of curiosity I flashed this baby on top of sac and ram deodexed rom for the s6 edge sprint variation and it works lol....only issue ive noticed so far is the "storage message" keeps popping up.

O_O that's suprising...ik there's some differences...hmm...well then. And I am going to try and get their method working soon. I tried to get it working earlier and got it compiling correctly but couldn't get it to boot sadly I will revisit it.

Going to give your kernel a run today and see how it goes! Always love to see more options around here.
I'm curious about the memory leak(s) you say you've patched. I wasn't really aware of any on the kernel side, can you give a bit of explanation here?

OMG... 2,88Ghz O.O
Thanks ! I download it now !! ????
trying..!
Overclock frequencies not running... Trying to figure out the problems.. People are free to send pull requests if they can help

Andy
Thanks a lot.....
A very huge salute to your work....
Please add kexec hard boot patch also(for multi rom)
Yeah.. Sure.. For now it is kept aside. Because over clocking the device was the main aim.. I will first fix the oc stuff with @acuiculator and then WIll add the kexec patch back...
Regards
Andy
Sometime over clocking freq. doesn't show in kernel auditor ...try synapse app...
Btw I am happy to see you here man....I know you from mmx a116 days ....

I am using default settings for this kernel. Booting is quick.. But games like asphalt stutter. Do u suggest any other settings for this kernel for balanced performance.?
Yeah.. Select a different governer and enable gaming boost in synapse. Planning to add lionheart governer. Gave good results on opo

No comparison. He is my good friend.. We work together... Thing is he is adding features and i optimize the builds... You can use his nuclear rom and kernel.. Even his kernel is a good option.. No comparison.. ??

Hey all... After many days and nights of work.. Compiled back again... This build lacks features as the may be hazardous.. Charge level interface was removed. Normal stock charging logic is too good.. Voltages already set to optimal. And no necessaries of hotplug... I have added showP original msm mp_decision which is real good one.. And stable one around.. Speaking about governer they have been kept as it is. Choice of people what to use..
Now talking about other changes.. I have searched for hell lot more msm8974 devices and finally I made a club combination of all the patches and changes for optimizations. You can have a change feel of what is done in my git source which is also now an Independent repo. You all may or may not understand the fundamentals of these commits made. Nor you may experience a gigantic performance improvements and battery life.. In short these are the lubricating the processor commits... They are meant to run the cpu GPU and all other components too smooth.. I will surely add some more of them... All other msm8974 devicee are too ahead of the race and we need to catch those.. This device is a beast and will overcome all the things I bet you.. All the best and thanks for such positive responses
