Vindicator Kernel
Supports F/I/S/K/L/T/W8 variants of 920 AND 925 devices
Intro:
This kernel was built to appeal to users who want something thats trimmed down as much as possible, yet still adds nice features that arent considered bloat. I spent a lot of time optimizing it and plan on spending several more hours just on optimizations. This kernel is also built with significant amounts of upstream code merged in, making it what many would deem a hybrid kernel. All credit goes to the real hard workers coming up with original ideas like Franco, Imoseyon, Ktoonsez, g.lewarne, 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. 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 apps that work well are Kernel adiutor and Kernel toolkit as well as synapse. You can also use VControl for a limited number of things. Synapse is now built into the kernel so simply install the app.
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 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 gets 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.
7. What is power aware scheduling?:
Power aware scheduling is a method of scheduling where we make the scheduler aware of the actual efficiency of the cores. As you know, the small cores are more efficient than the big cores. The existing method for scheduling work uses a more basic (if the load is above this point, then move it to the big cores) type of decision making. With power aware scheduling, the scheduler will schedule tasks based on its knowledge of the cores power efficiency. Typically this reduces performance, though it's likely not noticeable except for in some games. If you want more battery, enable this. If you want more performance or have lag in games disable.
More will be added as they come up and I think of them.

I personally use VControl to set my min freq to 200 for both, then I oc to 1600 on Apollo and 2200 on atlas. I then also disable fsync. That's it hope you like it! Let me know if you have any issues!
great job with another kernel!
I enabled CPU task packing, but when I check the current settings, it says "/sbin/VControl(239): cat: /sys/kernel/hmp/packing_enable: No such file or directory"

Thanks! Yea I had task packing enabled in a previous test but removed it prior to release. I decided to leave it in VControl in case I re add it. So just ignore it for now I'll probably remove it in r2

Kernel adiutor doesn't work for IO Scheduler. I recommend trying an app called Kernel toolkit. I'll probably add IO schedulers to VControl in the next update. Also there aren't tons of options on it atm. Mostly because its tweaked to run well on interactive governor, however I'll likely add conservative and ondemand in r2 as well.

The problem with kts governor is it would require merging a lot of other stuff that I don't need in order to make it work :/ however smartass is standalone. Is there other kernels for s6 that have it? If so it would be an easy addition most likely

Wooooooooahhhh! What? Two cores only?
The ONDEMAND governor either shuts down two of them, or it has Hotplug enabled, or there's just some kind of a mistake. I don't know, might be a bit of a noobish comment.
Can anyone solve this for us?

You can check if all 4 cpu's are used properly by starting Geekbench and than have a look. While geekbench is running, all 4 cpu's should be used.

ERMAHGERD! KERNEL!
Build 13.02.22
Welcome to my latest learning project. This is a result of me wanting to better understand how kernels are put together. I'm dipping my toes a bit at first, but I'm going to be doing quite a few different things as time goes on, and it's only going to get more complex and I get more comfortable with the process. Successful things will stick around, unsuccessful or little used features may get squashed out over time to keep things as lean as possible.
Features:
Compiled with Linaro 13.01 toolchain and -O3 optimizations
Upstreamed to Linux 3.0.63
Undervoltable - Use SVS compatible CPU control app
Kernel mpdecision enhancements by showp1984
ARM optimized multi-core topology scheduler by the Linaro team
New I/O Schedulers:
ROW - Read Over Write - A new I/O scheduler designed from the ground up specifically for flash based mobile devices. It is designed to give priority to reads without starving writes, but does not implement any fairness. (default scheduler)
Zen - noop with a touch of deadline. Aims for simplicity. Implements deadlines for fairness and gives priority to synchronous requests. No merging or reordering of operations is performed.
SIO - Simple IO - Another mix of noop and deadline. Implements deadlines for fairness and performs minimal merging. No priority or reordering of operations are performed.
Fast charge support - Allows any charger to be seen as AC. Requires app to toggle fast charge mode
zRam (compcache) support with frontswap - Allows creation of swap space using a portion of compressed RAM, and uses free uncompressed RAM when possible to minimize I/O operations
New CPU Governors
Lionheart - A performance tuned variant of conservative
Intellidemand - Intelligent ondemand. Scales relative to GPU load
Wheatley - Governor with a great sleep profile. Perfect for users with lots of idle time
All drivers integrated into kernel
Single installer for ICS AOSP and JB pmem AOSP versions
Loads of memory and I/O optimizations for a smoother overall experience
See changelog history for even more features
To enable zRam after installation, go into a terminal and execute "zramenable" as root. It will activate immediately and reactivate on every boot. To disable it, run "zramdisable" as root. It will remove the boot scripts and immediately disable zRam and recover the RAM used. Note to ROM developers: if you include this kernel in your ROM, these files will need to be extracted from this installer and included in yours if you wish to include zRam support.
Fast charge support requires the use of a compatible fast charge toggle app, such as this or this.

Kernelnewbies.org is amazing for learning the way Linux kernel works. I'm enjoying learning kernel developing because the compile is so quick I can actually debug and test without much stress. Welcome to the kernel party! If you look through github you'll find a wealth of tweaks and improvements to port.

Intro:
This is the first 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 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, Imo, Flar and Faux. Initially this was built as a kernel to compile with my ROM I'm working on but I decided I would let others get a chance to use it as well. 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.
For those looking for a similar experience, but much closer to stock, I suggest giving Zen Kernel a try!
Goal:Keep kernel as lean as possible while adding certain, desirable features 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. How Do I Enable Mako Hotplug?
To enable mako hotplug use your favorite kernel control app like faux or trickster. As of 1.8 it is the default hotplug. In trickster you have to turn off both mpdecision and intelliplug. In faux you need to simply select User Control in the Hotplug Section. The hotplug can be configured using Franko Kernel Updater App.
2. Does This Work With CM12 Theme Engine?
Yes, this works with CM12 Theme Engine and should work on all ROMs properly.
3. How Can I Force All 4 Cores Online All The Time?
First you must enable mako hotplug. Then you need to use Franco's kernel updater app or another app that allows you to tweak mako hotplug settings. In fku app select CPU manager then hotplug control. Change load threshold to 0. Additionally if you just want to make it use 4 cores more often. Lower this number below 80 as desired. This should also be possible to tweak via terminal however I've never used that method.
4. Does This Have D2W, S2W, etc?
Yes, those are part of LK which means they are include in this kernel.
5. Help! I think its making me bootloop!:
This may only apply to specific ROMs and I'm unsure ofnwhy it would change anything but users have reported this to fix the issue. If you are trying a fresh install of a ROM boot on stock kernel first, reboot, then install this kernel.
6. 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 sys/fs/pstore I then need the console one.
7. What Kernel Tweaking App Should I Use? What About For Tweaking Screen???:
I now Use synapse as my goto app for kernel tweaking since version 1.3. To control the screen I use the app made by Savoca who created the color control we use http://downloads.codefi.re/savoca/kcal
8. Why Add Zram? We Already Have 3gb Of Ram!
Zram was added in build 1.0 as an experiment of sorts to see how much is was actually being used. V 1.0 introduced a bunch of tweaks to the kernel that essentially make it use more ram in order to give better battery life and performance. Zram was put in place to offset this in a way.
9. Wut Is A LZ4?
LZ4 is a compression algorithm used by the kernel. LZ4 is currently the fastest supported option in the Linux kernel and had to be ported from upstream. It is significantly faster than XZ compression which is what we used prior. The downside is it results in slightly larger file sizes due to a lower compression ratio. However with modern hardware this should be moot. The gains should theoretically be noticed as a general performance bump. Boots should be faster. IO should be marginally faster. Anything that's compressing or decompressing stuff, such as ZRam and encrypted devices will utilize this in a big way. Because its compressing and decompressing so much faster it can also be assumed it is saving battery via less CPU cycles.
10. 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
11. Come on man. 35mhz is pointless bro!:
A common misconception is that if two frequencies run at the same voltage. They use equal power. In fact this couldn't be less true. The equation for power draw has four variables. Two of which are frequency and voltage. Essentially it is the frequency multiplied by the square of the voltage. Then you would take that and multiply it by a few other things such as capacitance. However that is irrelevant for our purposes as it will not effect the relative results. This means that 35mhz running at 500mv will use about 3x less power than 98mhz at 500mv. Now we say well what about compared to 300mhz? I can stably run that at around 650mv. Maybe slightly less. This equates to about 15x less power usage at 35mhz. Well now that we know that. Who cares? Its not like 35mhz will even get used. Its too low! I beg to differ. I would almost guarantee that if you are not running mpdecision 35 MHz will be within the top 3 most used frequencies. Most likely the top used below sleep. And every time it uses that over 300mhz you are saving 15x the power. Additionally 35mhz also runs at a cache frequency of 35mhz as opposed to 300mhz cache frequency and runs a lower bus speed/voltage saving additional power. The same goes for 98mhz. Hope this helps clear things up.
12. How Do I Disable BlueSleep Wakelock?
Open terminal emulator app. Type su then hit enter then type echo 0 > /sys/module/wakeup/parameters/enable_bluesleep_ws all on one line. It won't say anything but if you turn on Bluetooth and check your wakelocks you shouldn't see the wakelock there anymore. This needs to be set on each boot currently. If you experience Bluetooth connectivity issues don't disable this. To enable it again either reboot or run the same command with a 1 instead of a 0.
13. How Do I Use MultiRom???:
To use multi ROM first you must download the MultiRom App from this location http://tasemnice.eu/bordel/MultiROMMgr-v1.180.apk the play store version doesn't work with shamu yet. Then you will need to open it, go to settings and tap the version number until you are a developer. Then click override manifest URL and for manifest URL enter http://tasemnice.eu/multirom-test/manifest.json the. Go back to the main page. You should now have MultiRom and recovery boxes checked. Click install, reboot etc. To install a ROM. Download a ROM you like, go to twrp, click advanced,MultiRom,add ROM. Select internal storage and the Your zip file. Flash it but don't reboot! After that go back and select "list ROMs" select the ROM u just flashed still and click flash zip and select your gapps,supersu etc. After that simple reboot and select your new ROM on boot use the MultiRom app to manage your ROMs.
More will be added as they come up and I think of them.
Configuration Guide:
The following can be done using your favorite kernel tweaking app. I use synapse.
Clock Speed:
To begin I prefer to leave my max clock speed at the stock 2.649ghz. Set min CPU as low as it can go. As of current release this is 35. For the adventurous you can try 2.88ghz. Often I bump the voltage 12mVolts on 2.88 to be safe.
To find your CPU binning run this command in terminal emulator OR look at the first page in synapse near the bottom:
su (enter)
cat /proc/cpu/msm_acpu_pvs (enter)
(Put a space between cat and /proc)
note that the number may be displayed at the beginning of the next line.
It will then display a number from 0-15. 15 being the best. Don't stress over it too much if you score low, its not the end of the world. It just means you need marginally more voltage to run each frequency.
GPU:
As of Alpha 1.3 the GPU can now be over clocked to 700mhz. This is completely optional. To verify your over clock change the GPU governor to performance and see if it spikes to 700 every so often. If it does it worked! If it doesn't you may need to set the frequency to something else then back to 700 again. It remains to be seen what kind of benefits the GPU over clock will give but it is there for those who want it. The recommended GPU governor is the stock msm adreno one. If you encounter lag in games you can try changing it to performance temporarily while playing that game. Simple on demand is a more performance oriented governor.
Governor:
Most people will probably want to just leave this set to interactive. Its a really good governor that is being actively devolped by CAF, Google, and Franco. It also hooks into Francos CPU Boosting interface. Its "smarter" than OnDemand and generally considered to offer better battery life. If you want even more smoothness some consider OnDemand to provide a bit better performance, however you may get slightly worse battery life. This is because OnDemand ramps up to max frequency when there's is load put on the CPU and then slowly works its way down. Interactive scales through the frequencies on the way up and down which saves battery life but prevents it from jumping to max speed as fast if it is needed. Simms22 recommends using the OnDemand governor with "upthreshold" set to 98 and the sampling rate set to 15000. That is the default setting of the Trinity Kernel. Mistertac made the great suggestion of turning the max screen off frequency down to 600mhz if using the interactiveX governor. This will prevent any misbehaving apps from keeping CPU ramped up while screen is off and give better idle drain. The actual number you would have to type in would be 652800 for the screen off frequency. The Conservative Governor is greatly modified by franco, Its no longer a super slow governor as it once was. It also hooks into his cpu boost control interface meaning you get cpu boost when using it. Conservative prefers the lower frequencies, however so if you find yourself having lag, you may want to switch to another.
PowerSuspend:
The only working options in V1.6 of the PowerSuspend driver are lcd_panel and Userspace which can be found in the miscellaneous section of FauxClock. I suggest leaving it at the default choice of LCD_PANEL. In FauxClock if you navigate to the cpu idle/stats area you will be presented with more options. You should see a list of C-states. For example C0: wfi and C1: retention. These are essentially low power states that the cpu can enter to save power. The higher the C number the deeper the sleep. Last I heard, the optimal configuration was to enable C0, C1, and C3. Paired with lowered Retention voltages, this should give you a very low idle drain.
Hotplugging:
Next go to hot plugging section and disable MPDecision(make poor decision) and enable intelliplug or, enable Mako Hotplug(Franco's) by either selecting user control as your hotplug, or disabling both mpdecision and intelliplug. Tweaking for them is split up below.
IntelliPlug:
FauxClock allows you to further configure intelliplug. If you want more battery set it to Conservative (4) mode which will hotplug the CPU more conservatively and save you battery, essentially this means it will use less cores if it can. For most people, leaving it on Balanced (4) mode will be fine. If you want further battery savings you can set it to EcoPerformance (2) or even EcoConservative (2) which will only use a max of 2 cores. IntelliPlug is able to use a single core unlike Mako Hotplug.
Mako Hotplug:
As far as I know the only way to tweak Mako Hotplug is either through the terminal app, synapse or through Francos app. In Francos app select cpu manager, then Hotplug Control. The main one you will need is load threshold. The default is 80. The higher this number, the more load the cpu needs to be under before it will plug the 3rd and 4th cores. 80 is actually pretty good value for most people and it will use the extra 2 cores when it really needs them. If you want to force all 4 cores on for whatever reason, you can achieve this by setting the load threshold to 0. This will effectively disable hotplugging. Of course you can always find a middle ground as well.
Via Terminal:
The sysfs interface for mako hotplug is...
/sys/devices/virtual/misc/mako_hotplug_control
To adjust... Use echo commands...
Ex:
echo 0 > /sys/devices/virtual/misc/mako_hotplug_control/load_threshold
The above command would set the load threshold to 0.
Thanks Rignfool!
Voltage Control:
Next go to voltage control. I'm a Bin 5 and I can use a 48mVolt undervolt without becoming unstable. Rember! Never set voltages to apply on boot until you have tested them for a few hours first! Most people can probably get away with a 36mVolt undervolt and nearly everyone should use at least a -24mVolt UV. Also remember that if you are running an over clock you may not want to undervolt that frequency. If you find yourself running into freezes or random reboots remove the undervolt!
Thermal:
This kernel comes with the latest IntelliThermal Driver from Faux123, which is a highly configurable thermal driver, as well as Franco's Thermal Driver which is the stock option. It is recommended you use IntelliThermal over Franco's if you wish to customize the values. Change this option under the Thermal Manager section of FauxClock. The optimal settings that I have found are 70 degrees for frequency throttle, and then somewhere between 70 and 80 for core throttle temp, depending on how safe you want to be. Stock is 80 degrees. Leave all cores checked for both frequency throttling and core throttling. I also leave on GPU Thermal Control, but if you encounter periodic lag in games you may wish to disable it. I also leave Core Thermal Control on as well, though I'm not entirely sure what it does lol. Also FYI, the sliders beneath those two options are showing you the current status of them, they are not sliders you can move.....trust me...I tried for like 5 minutes before I realized and felt like a moron....
I/O Settings:
For I/O scheduler select FIOPS. FIOPS is superior to the other schedulers in nearly every way. It is a scheduler designed for flash storage which is what our phones use. My testing has shown that 1536 is the best readahead buffer. Less or more is detrimental.
ZRam:
ZRam is something designed to optimize the ram of a device. What typically happens when a device runs out of space in ram is it is forced to use something called swap. Swap is normally a partition of a hard drive or ssd depending on what is available where the ram can copy some of it's contents to free up space. The problem is even the fastest SSDs are many many times slower than ram. Android by default doesn't have swap, however it does use a low memory killer which essentially goes through and clears out apps that are in ram to free space. ZRam makes a compressed partition inside the ram itself which then acts as a swap partition. Basically when ram begins to fill up. It compresses data and sticks it in a sealed off area of the ram. This let's it stuff way more stuff into ram than normal. To enable ZRam I use fauxclock. Trickster for whatever reason does not work. In FauxClock go to memory settings, then set the Zram size to 300mb and click apply disk size. Then turn it on and set on boot. You have now essentially boosted the available ram via compression!
VM Settings:
There are numerous tweaks you can do to the VM. For this I use FauxClock but IK Kernel Aduitor can do this as well. In FauxClock navigate to memory manager. The first thing to tweak is an option called swappiness. This control is used to define how aggressive the kernel will swap memory pages. Higher values will increase agressiveness. I defaulted this to 10 however the default is 60. This will use more ram but give better performance. Next is VFS Cache Pressure. This controls the tendency of the kernel to reclaim the memory which is used for caching of directory and inode objects. The default used to be 200. Its now defaulted to 10 meaning more ram usage but more performance. Next up is dirty ratio and dirty background ratio. Some things pass through ram and stay there for a bit until they get flushed to the flash storage. These controls essentially dictate how long it should wait before flushing to the flash storage. The longer you can delay it the better performance and battery you achieve, at the cost of ram. Setting these higher will increase ram usage but increase performance. I recommend a background ratio of 30 and a dirty ratio of 50, however feel free to tweak them as you desire.
Color Control:
Next you may want to adjust Screen RGB, value, saturation, hue and contrast. WrinkleFree over in the Lean Kernel thread did extensive testing with a professional grade $1000 screen calibration tool. You can use this app http://downloads.codefi.re/savoca/kcal to control the screen.
For the most truly color accurate screen at D6500K:
Red - 248
Green - 246
Blue - 255
If you prefer a slightly cooler screen and the tuning the iPhone uses which is D7400K:
Red - 237
Green - 235
Blue - 255
More info can be found about color calibration here: http://forum.xda-developers.com/showpost.php?p=57265483&postcount=620
As for saturation. I like to turn it up a bit and make the colors pop a bit more so I leave it around 65. But quite honestly saturation,value,contrast,and hue are going to come down to tweaking it and finding what you like most. Have fun!
These settings are meant to be used as a starting point. Depending on your cpu binning and desires you will probably want to tweak these slightly to fit your needs. I'll add more as new features get added, I learn more, and I think of stuff to add Hope it helps someone!
Sweet! Good work man.

Are you trying to do this for a Benchmark?
Using the Faux app you can first set it to Intelliplug , then Performance (4) Cores and that should get you there.
If not, try setting it that way and reboot. I've noticed with this phone that I've had to reboot a lot for my changes to actually take correctly.
Cpu2 and cpu3 are stuck in performance...
And does anyone know where in sysfs to adjust mako hotplug?

Currently if you disable all hotplugs or if you use fauxclock to set it to usercontrol that enables Franco's mako hotplug. Thats why in an app such as faux you cannot easily force two cores online. However if you use Franco's updster app you can go to CPU manager then hotplug control and if you lower the load threshold it will hotplug more frequently. Setting this to 0 will force all cores online. Additionally as mistertac said. Using b intelliplug on either performance(4) mode or balanced(4) will use all 4 cores pretty frequently as well.
Introduction
This is a kernel for XT1572/XT1575 built from stock sources (marshmallow-6.0.0-release branch) with cherry picks from other kernels and some ports/mods done by me. It started as a personal build tailored to my preferences but just thought I'd share in case somebody might find it useful. My main goal is building the smoothest kernel I can get so performance is top priority.
This kernel is for stock ROM MPH24.49-18*
Disclaimer
Although I have experience with Linux kernels on desktops and servers this is my first Android kernel. I've been running this kernel on my XT1572 for a few days and seems pretty stable but that doesn't mean it's risk free. In fact I wouldn't dare to install it if you don't have a proper backup and some basic skills to deal with unexpected situations.

Donations
Although quite a deal of the important work has been done by the developers mentioned in the Credits section I spend many hours working on this. If you feel like helping me out I'd appreciate some tiny donations to cover some minor expenses.
Thanks to all of you who have donated, it's very much appreciated.
Profiles
One of the FAQ in most kernel related threads is "What are the best settings for .....?". This is the 10 million question since the usage pattern can be very different for each user. However, I understand less experienced users will appreciate some hints in this department, so that's why I'm posting some basic settings you can use as a starting point.
It's your job to further tune them to suit your needs. You should be able to modify these settings with whatever Kernel Control App you like the best, although not all settings are available in every app, in such a case tune those you can. The list is not complete (just the most importante settings) and is loosely based on Kernel Adiutor arrangement.
Please, keep in mind these are subjective values (based of personal preferences or popularity) and some people might like other settings for whatever reasons.

FAQ
I get random reboots, what is happening?
This kernel overclocks both clusters by default (a53: 1536MHz a57:2016MHz) and although this is very safe for most devices some CPUs are in the lowest spot of the binning spectrum and can't handle O/C very well. In such a case use a kernel control app (see the OP for references) to limit the maximum CPU frequencies, play with them until you find stable values for your device.
What are the best settings for battery life/performance/whatever?
That's hard to tell as every user is different. You can find some basic profiles in the OP you can use as a starting point. Notice the differences between then and build you own.
Why do some BIG cluster settings display N/A?
Why can't I change some settings on the BIG cluster?
If you get N/A or weird values when trying to change settings on BIG cores it means both are offline ("hotunplugged"). To work around this select "performance" governor, make your desired changes and then select you previous governor. You can also disable hotplug, make the changes, and enable hotplug again.
DoubleTap2Wake doesn't work sometimes. How can I get it to work all the time?
When device goes into suspend mode first tap is often missed (I suspect this is caused by Moto Sensor Hub). If you tap three times and get the timing right you'll probably make it work most of the time. As an alternative, Sweep2Wake works almost all the time
DT2W/S2W is acting weird or disabling itself
Make sure Moto Display is disabled. Open the Moto app, click on the stars in the top right corner, select Display and set to Off
Can I use this kernel in ROM X/Y/Z?
This is for stock ROM MPH24.49-18 only. It'll probably work on any stock based ROM but not guaranteed.
I use stock ROM but WiFi is not working
Due to some internal changes all modules had to be recompiled (WiFi included). In order to expose the new modules without modifying the system partition I had to implement a hack that requires root. Make sure you're properly rooted.
What's the deal with ZRAM?
ZRAM is a technique to increase memory available to the apps at the expense of CPU time. Memory space from apps not being used is compressed into a memory swap area and uncompressed on the fly whenever needed. As you can imagine this compress/uncompress process burns CPU cycles, potentially leading to worse battery life, lag and higher temperatures. Since this device comes with 3GB I can only think of one scenario where ZRAM can be beneficial: heavy multitaskers who care more about apps not reloading than battery life. For the rest of users enabling ZRAM doesn't make much sense in my opinion, and that's why it's disabled by default.
UPDATE: v0.10 includes an updated ZRAM driver that improves performance significantly. So much so that the benefits seem to outweigh the costs and it's been enabled by default.
What's the deal with KSM/UKSM?
Since many apps use the same libraries/resources it's very likely that at any given time there are multiple copies of the same data on different memory locations. KSM/UKSM tries to take advantage of that fact by scanning memory pages periodically and consolidating that multiple copies into a single shared copy. Much as like ZRAM it can have a good effect on heavy multitasking performance but at the expense of CPU cycles, and thus it's only recommended in the same scenario as ZRAM. Disabled by default
Ok, so do I enable ZRAM/KSM/both/neither?
I honestly think most users will be better off not using neither. If you feel like you need extra RAM I'd try KSM first, then ZRAM. Using both at the same time is overkill unless you are an ultra multitasker, in which case you should probably get a 4GB device anyway
How do I get WiFi on 6.0.1?
It's a modem version mismatch issue, you need to downgrade the modem. See this post.
Love to see more options! Thanks for sharing!!
Yeah this will be very good
Only One think that would be awesome try to implement the double tap to wake
Awesome! More custom kernels are always welcome are there many governors to choose from?

As I said on the OP my main goal is performance/smoothness, so I haven't specifically sought better battery life. That being said I'm getting about the same battery life as stock with better performance, that works for me.
Nevertheless, I'm very interested on how it works for other configurations and usage patterns.
@dirtyhank could you please add hotplugging to the kernel? Preferably one that allows you to select how many cores to run as well as which ones, as in run the two A57s and turn off the four A53s. Currently I'm running two A53s at 1.2Ghz and the remaining four cores are always off.
The screenshot is from Lolipop, and it is the only reason why I havent upgraded to MM. Turning off cores definitely makes a difference on battery life.
Also, if possible, adding a lower speed to the min speed. Will gladly test anything you thow my way. Thanks in advance.
Is there any chance for a CM13 version and a DT2W fork from elementalx?

Behold the wall of features
Android Q kernel is based from Google sources Android-Q branch with applied on top of it Samsung's kernel sources.
Since there is no more ELS repository for Android Q kernels.. I made a branch on the same repository on Github called [ZeusELS] which is purely a completely stock kernel with linux upstreamed always to the latest :angel: that's if anyone wanted to develop a new kernel from scratch also.. ZeusELS is based from Google sources Android-Q branch with applied on top of it Samsung's kernel sources too ! :fingers-crossed:
Download links are always at the end of this post
ZeusROM Features for Android Q
[*] It is just simply a replicate of DevBaseROM from @_alexndr but with more debloats and Zeus Kernel ready inside... just flash it and it is ready
Kernel Features for Android Q
Imported N960FXXS4DTA5 kernel sources
Used updated ramdisk N960FXXS4DTA5
The kernel is now compiled with GCC 10.0.1 along with LTO [Link Time Optimization] using the latest updates available for [isl,mpc,mpfr,zlib,etc..] GCC is self compiled with all kind of flags optimizations applied for maximum performance benefits and increase code quality
Using GCC LTO with all fixes and optimizations which leads to faster kernel operations and less kernel code bloating which will lead to less kernel size in which allows me to make room and use O3 kernel optimizations which will increase kernel size a little bit for results in significantly improved hackbench performance, which is a sign that overall performance in the kernel is improved. It works especially well in conjunction with LTO.
Implemented/Using [W.B.T.] Write Back Throttling driver which increases IO performance and smoothness of the kernel operating generally.. what it does is...
[Enable throttling of buffered writeback to make it a lot
more smooth, and has way less impact on other system activity.
Background writeback should be, by definition, background
activity. The fact that we flush huge bundles of it at the time
means that it potentially has heavy impacts on foreground workloads,
which isn't ideal. We can't easily limit the sizes of writes that
we do, since that would impact file system layout in the presence
of delayed allocation. So just throttle back buffered writeback,
unless someone is waiting for it.]
Implemented hybrid poll mode With this hybrid scheme, we can achieve big latency reductions while still using the same (or less) amount of CPU.
Implemented various patches from 4.10/4.14/4.19 imported
Simple LMK! first in the history of Samsung smartphones with all updates and patches applied
Undervolted everything on the SOC from RAM,CPU,Camera,CPU Bus,etc..
Reduced SELinux expensive calls for audit and disabled entirely
Updated SchedUtil to the latest patches & updates
Updated SchedUtilX to the latest patches & updates
Implemented IOwait and Use it + Make IOwait boost more energy efficient
Re-adjusted Samsung values on nearly everything volts,battery,ram,etc..
Using the S10/N10 Values to our beloved Note9 for Exynos hotplugging drivers
Using CPU Assist driver and updated its values
Disabled all kind of Debuggings, loggings, tracings aggressively kernel size is under 30MB!
Boost DevFreq whenever a new frame kicks
Added PowerSuspend Driver which will help on battery saving extensively and integrated it to display driver
Using HTC's Fsync named [Asynchronous Fsync] and made it working as default for Note 9
Implemented Sched Yields to force sleep whenever it kicks in
Moved MMC driver to SCHED_FIFO thread to reduce the impact of
load on IO performance.
Applied O3 compiling flags to Crypto drivers for increase performance
Tuned Up ALMK [Adaptive LowMemoryKiller] values and use it by default
Adapted and Implemented Force Reclaim driver from Lenovo and use it by default
Killed Samsung's poor RBIN memory management
Implemented CMA from Qualcomms devices and Use it as a replacment of Samsung's RBIN here what does it do..
[CMA pages are designed to be used as fallback for movable allocations
and cannot be used for non-movable allocations. If CMA pages are
utilized poorly, non-movable allocations may end up getting starved if
all regular movable pages are allocated and the only pages left are
CMA. Always using CMA pages first creates unacceptable performance
problems. As a midway alternative, use CMA pages for certain
userspace allocations. The userspace pages can be migrated or dropped
quickly which giving decent utilization.]
Introduce and Implement and Use GCMA [Guaranteed Contiguous Memory Allocator] read below what it does..
[While demand for physically contiguous memory allocation is still alive, especially in embedded system, existing solutions are insufficient. The most adapted solution is reservation technique. Though it serves allocation well, it could severely degrade memory utilization. There are hardware solutions like Scatter/Gather DMA and IOMMU. However,
cost of these additional hardware is too excessive for low-end devices. CMA is a software solution of Linux that aims to
solve not only allocation but also memory utilization problem. However, in real environment, CMA could incur unpredictably slow latency and could often fail to allocate contiguous memory due to its complex design. We introduce a new solution for the above problem, GCMA (Guaranteed Contiguous Memory Allocator). It guarantees not only memory space efficiency but also fast latency and success by using reservation technique and letting only immediately discardable to use the area efficiently. It shows 15 to 130 times faster and more predictable allocation latency without system performance degradation compared to CMA.]
Implement binderfs for Andorid IPC
Wakelock Blocker is used by default and it already blocks the needed wakelocks by default
Added DropCache feature which will help with memory management on the long run
Tuned Adaptive LMK to work Asynchronously
Implemented ZRAM Deduplication feature which will..save amount of memory usage by zram. Read below the benefits...
[Android is one of the biggest users to use zram as swap and it's
really important to save amount of memory usage. There is a paper
that reports that duplication ratio of Android's memory content is
rather high. And, there is a similar work on zswap that also
reports that experiments has shown that around 10-15% of pages
stored in zswp are duplicates and deduplicate them provides some
benefits.]
Implemented ZSWAP same-filled pages handling feature look below what does it do..
[Zswap is a cache which compresses the pages that are being swapped out
and stores them into a dynamically allocated RAM-based memory pool. This patch adds a check to identify
same-filled page before compression of the page. If the page is a
same-filled page, set zswap_entry.length to zero, save the same-filled
value and skip the compression of the page and alloction of memory in
zpool. Improvemnt in preformance varies between 19% ~ 32% increased performance in store time & 49% ~ 85% increased performance in loading time]
Implement B-tree function and Made ZSWAP to Use it by default which will lead to the following IO bogo operations: * original: 73778.8 * btree: 393999
WireGuad using the latest version always
Added MoroSound!
Brought a collection of Paranoid Android & Xiaomi patches to our beloved Note9 devices
Tuned UFS net boost table
Speed up scatterlist to roughly a 2x performance gain & Speed up cache entry creation for mbcache2
Implemented some fucntions & drivers from 4.14 Kernel and use it on Note 9 [which have 4.9 Kernel]
Using Jump Lable on the kernel read below what does it do..
[This option enables a transparent branch optimization that makes certain almost-always-true or almost-always-false branch conditions even cheaper to execute within the kernel.
Certain performance-sensitive kernel code, such as trace points, scheduler functionality, networking code and KVM have such branches and include support for this optimization technique.
If it is detected that the compiler has support for "asm goto", the kernel will compile such branches with just a nop instruction. When the condition flag is toggled to true, the nop will be converted to a jump instruction to execute the conditional block of instructions.
This technique lowers overhead and stress on the branch prediction of the processor and generally makes the kernel faster.]
Using Jump Lable Relative References on the kernel read below what does it do..
[Reduce the size taken up by absolute references in jump label
entries themselves and the associated relocation records in the
.init segment, add support for emitting them as relative references
instead.This reduces the size of the __jump_table by 33%, and
gets rid of the RELA section entirely.]
Improve ION cache accounting
Added Fingerprint Boost Driver
Low Memroy Killer features... LMK Fast RUN, OOM Reaper, Process reclaim
Updated ZRAM & ZSWAP with LZ4,ZSTD,LZO compression algorithm
Implemented Devfreq Boost driver and updated it... look below what it does
"This driver boosts enumerated devfreq devices upon input, and allows for
boosting specific devfreq devices on other custom events. The boost
frequencies for this driver should be set so that frame drops are
near-zero at the boosted frequencies and power consumption is minimized
at said frequencies. The goal of this driver is to provide an interface
to achieve optimal device performance by requesting boosts on key
events, such as when a frame is ready to rendered to the display."
Introduced a centralized Energy Model (EM) management framework which aggregates the power values provided by drivers into a table for each performance domain in the system.

Applied PSI driver on RAM , CPU , IO Drivers... see what it does...
[When systems are overcommitted and resources become contended, it's hard to tell exactly the impact this has on workload productivity, or how close the system is to lockups and OOM kills. In particular, when machines work
multiple jobs concurrently, the impact of overcommit in terms of latency and throughput on the individual job can be enormous.
In order to maximize hardware utilization without sacrificing individual job health or risk complete machine lockups, this patch implements a way to quantify resource pressure in the system.]

Updated F2FS to the latest updates taken from Android-Q Google sources! needs ROM modifications to get F2FS working on /data partition
HMP is synced with Googles latest scheduler changes
Kernel Features for Android Pie
Imported N960FXXU4CSK1 kernel sources
Used updated ramdisk N960FXXU4CSK1

Using always the latest GCC 10 Build with LTO self compiled
Optimized UKSM function and KSM along with it
Add ROW scheduling algorithm & ROW driver... mechanism of it is...
[The ROW scheduling algorithm will be used in mobile devices as default
block layer IO scheduling algorithm. ROW stands for "READ Over WRITE"
which is the main requests dispatch policy of this algorithm.
The ROW IO scheduler was developed with the mobile devices needs in
mind. In mobile devices we favor user experience upon everything else,
thus we want to give READ IO requests as much priority as possible.
The main idea of the ROW scheduling policy is:
If there are READ requests in pipe - dispatch them but don't starve
the WRITE requests too much.]
Added battery Store mode [used to limit charging] advanced use only & Unstable power detection driver and made it optional through HKTweaks app (Google it)

Using Galaxy S10 + Note 10 HMP extracted drivers combined and implemented it to our be loved Note 9!
Introduced [Host Performance Booster] HPB driver from Pixel 3! & Adapted it to our Note9!! Please read below what HPB can do...
[HPB is essentially caching of the NAND chip’s FTL (flash translation layer) L2P (logical to physical) mapping tables into the hosts (SoCs) main memory. This allows the host driver to look up the target L2P entry directly without betting on UFS’s limited SRAM to have a cache-hit, reducing latency and greatly increasing random read performance. The authors of the feature showcase an improvement of 59-67% in random I/O read performance due to the new feature. It’s worth to mention that traditional Android I/O benchmarks won’t be able to show this as as those tend to test read speeds with the files they’ve just created.]
(Source of this info ---> Here)
Added Ainur audio driver for those who want to use DTS Audio mods
Applied PSI driver on RAM , CPU , IO Drivers... see what it does...
[When systems are overcommitted and resources become contended, it's hard to tell exactly the impact this has on workload productivity, or how close the system is to lockups and OOM kills. In particular, when machines work
