Hi Folks!
Here i present you Arsenic Kernel. Based on close to AOSP - Slim Kernel, Thanks to @Martinusbe for a perfect and stable base.
Started this project for unofficial builds of ROMS with keeping performance in mind without compromising on battery backup. It was supposed to be included in my personal builds of roms but some users requested to release it for other roms so here it is with anykernel method.
zip doesnt offer any module changes and doesnt mess with the ramdisk so you can feel free to dirty flash it over prebuilt kernel or Arsenic's previous versions(Dont forget to clear data of kernel adiutor or anyother kernel control app you're using before).
Keeping op short and simple and with keeping New users in mind, here is a brief description about kernel:
Features:
Supports all AOSP/CM based roms except OOS and OldDroid's AOSP.
Supports Sultanized roms.
Supports Both Android 6.0.x and 7.x.x
Built with Latest GCC 4.9 toolchain from Google.
Device and target flags enhancements and improvements, etc.
Kernel compressed with XZ.
Upstream CAF fixes and changes.
USB Fast Charge.
Switched to -O2 Optimization level.
Adreno idler.
Krait C-states customizations.
ExFat and F2FS support.
Disabled Lots of useless Debuggings and Redundant Code.
New Governors and I/O Schedulers.
Optimized sfck compression.
Various Upstream backports.
SOC Driver Tuneables.
Enabled Arch Power.
Optimized RWSEM Algorithm.
FiiO USB DAC driver for better input detection
Options to disable various wakelocks.(Use them wisely!)
TCP Congestion algos (like westwood,cubic etc).
CPU Input Boost.
Voltage Control.
Various under the hood Battery and performance improvement patches(Advance users can look at my git, each commit is there with proper explaination).
Stability and Battery backup at its Peak!
Available Govs: conservative, impulse, interactive, ondemand, performance, powersave, smartmax, userspace, wheatley, yankactive, zzmoove.
Available I/O Scheds: row, bfq, fiops, noop, cfq, ZEN and Tripndroid.
Keep an eye on the changelog for more/newly add features as this list wont be updated regularly so either have a look on Changelog or just flash Arsenic and explore yourself..!
FROM R24, ONLY NEW MM BOOTLOADER WILL BE SUPPORTED!
MAKE SURE YOU ARE RUNNING A ROM WITH NEW MM BOOTLOADER FOR R24+
if you are still running roms with old bootloader then flash R23..!
Follow THIS GUIDE to Upgrade Bootloader for future support.
From R46, Builds are divided according to the gesture implementation of the ROM. READ THIS before downloading/flashing the builds!

(Flash correct build depending on the ROM you are using)
For OOS Compatible Build : Head over to THIS THREAD
Keep in mind:
You can dirty flash it over prebuilt kernel of your rom or any previous version of Arsenic but its always prefered to flash stock kernel or dirty flash your rom if you are already running a custom kernel to avoid any conflicts or problems.
Compatible with both AOSP(Except OldDroid's AOSP) and CM Roms BASED ON Android 6.0 and 7.X
Bugs and issues:
Report if you find any.

F.A.Q's :
Can you add [this] and [that] feature to arsenic?
Something I pride myself with this kernel is that it does not have a bunch of random, useless features or patches mashed into it. Everything put into this kernel is thought out well and tested. I see a lot of works being made popular because it has [this] and [that] feature when really, it's nothing revolutionary(atleast to me). As a matter of fact, most things added to any kernel will not make it 5x better than any other kernel. Most of the time, simple is better; and in this case it definitely is!
Any plans of upstreaming the linux version?
No, and i wont. Though i have test builds ready but they wont make up to the release version. Upstreaming linux version doesnt make much difference infact it does degrade Arsenic's performance. Reason why i'm against it is that I've removed almost all possible useless redundant code and debugging present in it to improve kernel in all aspects, upstreaming will not only add alot of redundant code but will also add debugging functions for those redundant code! Which will not only increase kernel's size but will heavily impact on kernel's performance, battery backup and stability. Currently 3.4.0 is "THE" most stable branch and i'd like to keep it.
Why MPDecision? Why not remove the hell outta it?
You want me to remove something which was developed by some of the finest engineers of this world and is currently being shipped on almost all android devices..? Dont you think there would have been a reason why Google chose MPDecision over anyother hotplug.
What most of the users arent aware of is that, MPDecision works best with the default thermal solution, all it needs is a little touch..
As far as adding an additional hotplug, m still thinking about it.
Why so rude?
Not rude, Determined. Everything i do has a reason behind it. And I do sometimes accept feature request if they seems to be worthy.

Two new kernels in the past few days?? Cool! I will be trying this one out as well! I'll install tonight and it'll get a test run of my work day tomorrow.
Great job. I
Oh and in your profile recommendation, DO NOT use zzmoove with agressive power saving as it has conflicts with its got plug and generally isn't a good thing in general. Oh and for read ahead, use 128 for internal and 1024 for 16gb external, 2048 for 32 and up.
128 won't harm performance at all and should increase stability.

No conflicts so far with Mpdecision so aggressive is a go for me. Read ahead is higher for internal as its much faster than external memory cards, it depends on class/speed of memory card. Since internal is much faster so it can use upto 1024 and for ext 384 is recommended. Do shed a light if m wrong.
Most users doesnt use a class 10 ext. Memory card so read ahead for ext shouldnt exceed 384 imo.

Aggressive power saving isn't referring to mpdecision. It overrides zzmooves hotplug driver. As for read ahead, its actually vice versa. You don't need a higher value for internal storage because as you mentioned, its much faster. For every 8gb of external data the rule of thumb is generally a 512 bump.
Sorry I haven't had time to take a look at TG again...

Zzmoove's hotplug driver..? Shed some more light on it plz cz kernel isnt shipped with an option to change hotplug, mpdecision is working good so far with zzmoove and aggressive power saving mode.

Kindly remove this, this might be misleading some New users as pipe isnt supported on linaro 4.9 and i already enabled cortex a15 optz, and no errors in kernel so far
Thnx

Zzmoove has a hot plug driver. Look under Alpha 0.3:
http://forum.xda-developers.com/galaxy-s3/development/info-cpu-governor-zzmoove-t2326544
Aggressive power savings overrides its ability to manipulate cores, so beforehand you either have to disable it or forget about aggressive power saving to avoid conflicts. Yes, mpdecision is a hot plug, but governors can have their own solutions too. PegasusQ has hot plugging too

I agree with the hotplug part but as far as i remember i cant see any option to enable zzmoove's hotplug and unless and untill mpdecision is on it wont get activated. For reference you can see boeffla's config app, it has option to change hotplug from default one to zzmoove's but in kernel adiutor its not available and unless you turn off mpdecision(which i dont recommend at all with my kernel) using power saving mode wont affect your device.

Nitzz said:
I agree with the hotplug part but as far as i remember i cant see any option to enable zzmoove's hotplug and unless and untill mpdecision is on it wont get activated. For reference you can see boeffla's config app, it has option to change hotplug from default one to zzmoove's but in kernel adiutor its not available and unless you turn off mpdecision(which i dont recommend at all with my kernel) using power saving mode wont affect your device.

I simply stated that it would cause conflicts... If a tree falls in the woods and nobody is there to see it then does it still make a sound?
Love the kernel great work. So much optional tuning in kernel adiutor. Comes with many governors to choose from. The suggested settings are well balanced battery, performance and zero lag.
Well, the Kernel is Solid, no complaints at all. Great work Nimit !
Attached Battery Graph for 2nd cycle.
Updated to R3..!
Updated to R3
R3(28/7/2016)-
*cortex a15 optimizations
*Add add sensor_ind wakelock toggle
*ARM: smp: Wait just 1 second for other CPU to halt
*Optimize task_sched_runtime()
*tick: Upstream fixes
*Shift to GCC Toolchain from Linaro (Much smoother and Better Battery backup as compared to linaro builds)
Recommended update!
Note: if you face a glitch in kernel adiutor regarding min. freq then plz ignore it as its just a glitch, shows current freq (on which CPU is scaling) for a sec and then will come back to the set one (300 Mhz by default). Freq scaling is normal and kernel works just fine!
The kernel is running nothing but fantastic!
Just updated to R3. Reminds me of leankernel back in the days. Smooth and stable.

This is a AOSP kernel for the lte.
since 4.2 is pretty stable I am going to start updating the changelog for it.
What is a kernel?
In computing, the kernel is the main component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components).

[IMG]http://forum.xda-developers.com/attachment.php?attachmentid=1479575&stc=1&d=1352840345[/IMG]
here is a little explanation of kernel based thermal and mpdecision control
What is msm_thermal?
Kernel based 3-phase thermal control!
This replaces your /system/bin/thermald binary which is renamed by the installer to thermald_backup.
Check /sys/kernel/msm_thermal/conf/ for the thermal configuration
allowed_max_high = highest threshold (phase 3)
allowed_max_low = remove the throttling if we cooled down to this (clr_thrshold)
allowed_max_freq = max frequency if throttled (limit)
[...]mid[...] = same as above, just for phase 2
[...]low[...] = Lowest threshold (phase 1)
check_interval_ms = how often shall we check? (sampling rate)
Default: 1000ms (=1sec)
If you want to see msm_thermal doing it's job:
Code:
adb shell cat /proc/kmsg | grep 'msm_thermal'
What is msm_mpdecision?
100% kernel based multi core decision! (should cpu1 be online or not?)
This replaces your /system/bin/mpdecision binary which is renamed by the installer to mpdecision_backup.
Check /sys/kernel/msm_mpdecision/conf/ for the configuration.
startdelay = time until mpdecision starts doing it's magic (70000)
delay = time between checks (500)
pause = if something else plugs in the cpu, fall asleep for 10000
scroff_single_core = if the screen is off, don't plug in cpu1 (1)
nwns_threshold_up = runqueue threshold, if this is reached cpu1 will be hotplugged (35)
nwns_threshold_down = runqueue threshold, if this is reached cpu1 will be unplugged (5)
twts_threshold_up = time threshold, this amount of time must have passed (250)
twts_threshold_down = same as above (250)
enabled = enable(1) or disable(0) mpdecision. This does not affect scroff_single_core!
idle_freq = a value against that will be checked if a core +/- is requested. (486000)
If cpu0 is below that value and a core up of cpu1 is requested, nothing will happen.
If cpu1 is above that value and a core down of cpu1 is requested, nothing will happen. (otherwise it would now put down cpu1 even though it is still working)
(all times are in ms)
NOT RESPONSIBE IF YOU BRICK,DROP,LOSE YOUR DEVICE. FLASH AT YOUR OWN RISK[/B
What is FSO?
Fso has greater speed, but there is a chance of corrupting if the phone has a random reboot.
Non-fso is what a stock kernel is and does not have the corruption issue.
It's a trade off, performance for stability or visa versa
If you have issues with reboots viperboy has created a script to increase voltages which may help with stability for the rebellious phones thanks viperboy

Flashing asap
Also what are the smartass2,intellidemand,savadgedzen,2 phase ondemand, and lionheart do, specifically what are the pros and cons?
Ive never heard of those before. But i have heard and used the other ones listed above.
Nice. Will give this a go next time I flash cm10.

For those of us that are S-ON and dev unlocked, how do we go about installing this? It's not in a .img file so no flash image gui or fastboot.
Can someone repackage it?

If I'm not mistaken, the image you need is in the flashable zip. Just download the zip, extract it somewhere, and grab the IMG.
May be wrong though. Been a while since I actually looked inside of a kernel zip haha

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...

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.

Installation instructions
Download ZIP and flash from TWRP/Flashify. Read the following notes carefully before flashing.
Important notes:
This kernel is still experimental, make a proper backup first
You need to be rooted
DO NOT play with DT2W/S2W before reading the release notes and the update
In case you want to tune some parameters (ie: CPU frecuencies) I recommend you install EX Kernel Manager, Kernel Adiutor or Kernel Adiutor-Mod.
If you're using Kernel Adiutor to control vibration or TCP congestion read this.

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

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?

Getting bootloop on TruePure rom 2.4. Anything I can try to avoid bootloops?
The Schwifty Kernel (Yeahhh, Get Schwifty)
Hello guys welcome to the Schwifty Kernel! If you watch the show "Rick and Morty" you will understand why I named it this if you don't understand well either youtube it or just don't worry and enjoy the sh*t out the kernel anyways hehe. Alright lets get Schwifty, here's all the info about the kernel in a way that will help you decide how you want to set up your phone! The second post will contain changelogs and third post, well not sure yet. But enjoy!!
Basic Specifications/Information:
Based On LS997ZV7 OpenSource (Thanks LG)
NO Static Screen
Install Includes Root
Allow 5-10 to settle in after booting up for better usage
Take the time to read all the information to get an understanding on the kernel (Will help with less bug reports)
If you report a bug please search before posting and give all information about your issue (Such as rom, kernel version, kernel setup... ect)
I will edit the page with dates when there is something new added such as govenors, schedulers ect...
I/O Scheduler Information - I/O:
FIOPS - This new I/O scheduler is designed around the following assumptions about Flash-based storage devices: no I/O seek time, read and write I/O cost is usually different from rotating media, time to make a request depends upon the request size, and high through-put and higher IOPS with low-latency. FIOPS (Fair IOPS) ioscheduler tries to fix the gaps in CFQ. It's IOPS based, so it only targets for drive without I/O seek. It's quite similar like CFQ, but the dispatch decision is made according to IOPS instead of slice.
SIO - Simple I/O aims to keep minimum overhead to achieve low latency to serve I/O requests. No priority queue concepts, but only basic merging. SIO is a mix between noop & deadline. No reordering or sorting of requests.
NOOP - Inserts all the incoming I/O requests to a First In First Out queue and implements request merging. Best used with storage devices that does not depend on mechanical movement to access data (yes, like our flash drives). Advantage here is that flash drives does not require reordering of multiple I/O requests unlike in normal hard drives.
DEADLINE - The goal of the Deadline scheduler is to attempt to guarantee a start service time for a request. It does that by imposing a deadline on all I/O operations to prevent starvation of requests. It also maintains two deadline queues, in addition to the sorted queues (both read and write). Deadline queues are basically sorted by their deadline (the expiration time), while the sorted queues are sorted by the sector number. Before serving the next request, the Deadline scheduler decides which queue to use. Read queues are given a higher priority, because processes usually block on read operations. Next, the Deadline scheduler checks if the first request in the deadline queue has expired. Otherwise, the scheduler serves a batch of requests from the sorted queue. In both cases, the scheduler also serves a batch of requests following the chosen request in the sorted queue.
BFQ - Instead of time slices allocation by CFQ, BFQ assigns budgets. Disk is granted to an active process until it's budget (number of sectors) expires. BFQ assigns high budgets to non-read tasks. Budget assigned to a process varies over time as a function of it's behavior.
BFQIO - Enable hierarchical scheduling in BFQ, using the cgroups filesystem interface. The name of the subsystem will be bfqio.
ZEN - ZEN is based on the Noop, Deadline and SIO I/O schedulers. It's an FCFS (First come, first serve) based algorithm, but it's not strictly FIFO. ZEN does not do any sorting. It uses deadlines for fairness, and treats synchronous requests with priority over asynchronous ones. Other than that, it's pretty much the same as Noop blended with VR features.
MAPLE - Maple is based on the Zen and Simple I/O schedulers. It uses ZEN's first-come-first-serve style algorithm with separate read/write requests and improved former/latter request handling from SIO. Maple is biased towards handling asynchronous requests before synchronous, and read requests before write. While this can have negative aspects on write intensive tasks like file copying, it slightly improves UI responsiveness. When the device is asleep, maple increases the expiry time of requests so that it can handle them more slowly, causing less overhead.
Governor Information - CPU:
Interactive - Interactive scales the clockspeed over the course of a timer set by the kernel developer (or user). In other words, if an application demands a ramp to maximum clockspeed (by placing 100% load on the CPU), a user can execute another task before the governor starts reducing CPU frequency. Because of this timer, Interactive is also better prepared to utilize intermediate clockspeeds that fall between the minimum and maximum CPU frequencies. It is significantly more responsive than OnDemand, because it's faster at scaling to maximum frequency. Interactive also makes the assumption that a user turning the screen on will shortly be followed by the user interacting with some application on their device. Because of this, screen on triggers a ramp to maximum clockspeed, followed by the timer behavior described above. Interactive is the default governor of choice for today's smartphone and tablet manufacturers.
Ondemand - Ondemand is one of the original and oldest governors available on the linux kernel. When the load placed on your CPU reaches the set threshold, the governor will quickly ramp up to the maximum CPU frequency. It has excellent fluidity because of this high-frequency bias, but it can also have a relatively negative effect on battery life versus other governors. OnDemand was commonly chosen by smartphone manufacturers in the past because it is well-tested and reliable, but it is outdated now and is being replaced by Google's Interactive governor.
Performance - Sets the frequency at the maximum available frequency. This governor always returns UINT_MAX as frequency so that the DEVFREQ framework returns the highest frequency available at any time.
Powersave - Sets the frequency at the minimum available frequency. This governor always returns 0 as frequency so that the DEVFREQ framework returns the lowest frequency available at any time.
Userspace - Sets the frequency at the user specified one. This governor returns the user configured frequency if there has been an input to /sys/devices/.../power/devfreq_set_freq. Otherwise, the governor does not change the frequnecy given at the initialization.
Blu_active - A new cpu governor developed by eng.stk (featured in his Code_Blue kernels) based on interactive with upstream caf patches and ondemand governor bits too. This governor is mainly focused on performance like the other things the developer creates but it is also well balanced for gaming and general usage.
ElementalX - ElementalX is basically a multiphase Ondemand governor that aims to achieve the best balance between battery life and performance. By default, it is more conservative than Ondemand as it does not ramp up often for most phone activities. If there is a graphics load detected, the governor will switch to a two-phase Ondemand behaviour where different max frequencies are used depending on the load increase. ElementalX comes with input boost enabled by default lowering the sampling rate and increasing the frequency to improve responsiveness.
Nightmare - A PegasusQ modified, less aggressive and more stable. A good compromise between performance and battery. In addition to the SoD is a prevention because it usually does not hotplug.
Darkness - It's based on nightmare but more simple and fast, basic configs but very complex structure. It is an updated version of the nightmare gov, so far it is quite stable in tests.
Chill (NEW 5/15) - Use the CPUFreq governor 'chill' as default. This allows you to get a full dynamic frequency capable system by simply loading your cpufreq low-level hardware driver. A conservative based governor that aims to provide more aggressive battery savings while screen is off.
Dance Dance - Based on conservative with some smartass features, it scales accordingly to conservatives laws. So it will start from the bottom, take a load sample, if it's above the upthreshold, ramp up only one speed at a time, and ramp down one at a time. It will automatically cap the off screen speeds to 245Mhz, and if your min freq is higher than 245mhz, it will reset the min to 120mhz while screen is off and restore it upon screen awakening, and still scale accordingly to conservatives laws. So it spends most of its time at lower frequencies. The goal of this is to get the best battery life with decent performance. It is a performance focused governor but also blends with some battery savings.
GPU Governors:
Adreno Idler - It is an idling algorithm, an efficient workaround for msm-adreno-tz's overheads. Main goal is to lower the power consumptions while maintaining high-performance. Since msm-adreno-tz tends to *not* use the lowest frequency even on idle, Adreno idler replaces msm-adreno-tz's algorithm when it comes to calculating idle frequency(mostly by ondemand's method). The higher frequencies are not touched with this algorithm, so high-demanding games will (most likely) not suffer from worsened performance.
Simple - An open-source alternative to Qualcomm's closed-sourced governors. Developed by Faux123, it is highly customisable which will allow more fine-grained control over how the GPU scales up and down.
simple_ondemand[/b] - As the name implies, it is a simpler version of the CPU governor ondemand. simple_ondemand will ramp up the frequency when a load is detected. It has a good balance between performance and battery savings.
msm-adreno-tz - The default GPU governor used by Qualcomm for their adreno GPUs. It is based on the ondemand governor but is biased towards performance, therefore it should give better performance in games but less battery life.
Performance - As the name suggests, this keeps your GPU running at the max frequency. This is a governor if you want the best possible experience in games but you don't care about your battery life.
Powersave - Like the CPU governor, this keeps your GPU running at the lowest possible frequency. Best battery life, extreme lag in games.
Userspace - This governor basically allows the user is able to set a desired frequency for the GPU to run at.
cpubw_hwmon - A hardware monitor based governor that attempts to determine bandwidth (BW) needed by CPU and other hardware. Because it samples bandwidth using polling intervals, it has been made to be biased towards performance to compensate for the possible slower response times during heavy loads.
MSM Cpufreq - The MSM CPUfreq governor determines the CPU to DDR bandwidth vote based on the current CPU frequency of all the active CPUs. In other words, this governor scales based on CPU usage which could mean more performance.
Other Information:
Moved Core Control To Kernel - Moved core control from out-of-tree module into the kernel proper. Core control monitors load on CPUs and controls how many CPUs are available for the system to use at any point in time. This can help save power. Core control can be configured through sysfs interface.
Moved Core Control Trace Events To Scheduler
Added A Knob To Disable The core_ctl (Core Control) - The CPU hotplug tests does not work with core_ctl compiled statically into kernel. Provide an interface to disable the hotplug by core_ctl.
Enabled LZ4 Compression & Added ExFAT Filesystem
Fixed Various Issues
And a whole lot of other sh*t

Before the thread blows up in requests for other variants. I am currently NOT building for other variants. When I have time I may consider it but until then only support LS997 im sorry! However this might (key word might) work for the Verizon variant and US996.
Been so long since I've used governors...what do you recommend to adjust them all? I used to use trickster back in the day but that has since changed.
Excellent work. Can't wait to through it on my phone.

I use Kernel Adiutor.
I flashed this kernel then had the sudden urge to sh*t on the floor.
Really smooth preformance with OBAR. Best ROM and Kernel combo for the sprint variant yet. Thanks!
This kernel has fixed my bluetooth annoyances.
Bluetooth instantly and automatically switches from one device to another when I move from work truck to car.
Sooooooooooo happy. ?
R'uh r'oh. Spoke to soon. Having sound issues but only with videos opened in facebook browser. I can live with this.

FAQ
Q: With which ROMs this Kernel is 100 % Compatible ?
A: Currently only with Android 9 custom ROMs, but Samsung stock ROM is recommended.
Q: Is this Kernel 100 % Safe ?
A: Yes.
Q: Will this Kernel Overheat the Phone if I use Highest Settings ?
A: No, you can't do anything wrong. Your phone has hard- and software overheat protection.
Q: How to Revert all Changes Made by this Kernel ?
A: Flash latest 3-parted stock ROM with ODIN or flash the Samsung kernel from my download site.
Q: How to bypass SafetyNet ?
A: Anable MagiskHide in Magisk app.
Q: How i can Tune this Kernel ??
A: Everytime you install or update this kernel you will face an red (demo) app "A2N Kernel Control..." open this app, and it'll redirect you to Google Play to get the full version (blue app).
Q: Can i use and Tune your Kernel with other Kernel Manager Apps ?
A: Yes, but you need first to unlock kernel with the A2N app full version.
Q: I've Installed the Full Version of the App, Will it Change any Kernel Settings by Default if i do not Change them ?
A: No, default app settings = default kernel settings.
Q: I've the Full Version of the A2N Kernel Control App, Do i still need the Demo Version of the App ?
A: Yes, there are some special features in-app-menu like "Fake Enforce" and debugging features for easy bug reports.
Q: How to Charge from 10 % to 100 % In just 1 h ?
A: E.g. set "AC Current Max" and "Maximum Charging Temperature" to the Max.
Q: How to get Max Speed for e.g. Highest FPS in Games ?
A: Set BIG / LITTLE CPU and GPU Freq to the Max, but avoid to use "unsafe" Freq's.
Then set CPU / GPU --> DVFS --> "Maximum Temperature" to the Max.
Now you can even cook an egg on your phone !
Q: Will my Custom A2N Settings Survive if i install Stock Kernel and then going back to A2N Kernel ?
A: Yes, as long as you don't uninstall it.
Q: Can i use your Kernel Control App with other Custom Kernels ?
A: No, it's not universal kernel manager app.
Q: My A2N App is Crashing after an Update, how to fix it ?
A: Re-install it. If it doesn't help, wipe dalvik-cache in recovery.
Q: My A2N App shows: "Please check your internet connection" - But i've good internet connection. - How to fix it ?
A: Settings --> network settings --> use private DNS server like "dns.adguard.com" - confirmed to work by user @Arnz09 - see his post here.
Otherwise send me a pm with the screenshot and you current location (city)
Q: Why I get lower benchmark scores with this kernel compared with the Samsung kernel ?
A: This kernel uses by default Max CPU/GPU DVFS Temp 65 °C to reduce the device heat. You can buy the full version of the A2N app to set the DVFS Temp up to 100 °C to get higher scores than on stock kernel.
Q: Why the Android Battery setting "fast charging" has no effect on this kernel ? - It charges always with around 1500 mA.
A: Because it would conflict with the built-in charger control.
The default charging current of approx. 1500 mA means no fast charging by default, even if you actually see "fast charging" in the notification section. This is also useful to reduce battery stress and device heat. To charge even with higher speed/current than on stock kernel you need to buy the full version of the A2N app.
Q: Why I've to pay money for just changing kernel settings ?
A: Well quality has its price. Also nobody forces you to use this kernel.
You can flash other custom kernels or flash the Samsung stock kernel from my download site. Good luck !
Q: When we get an update ?
A: This kernel is almost 100 % stable and works very well. Also this phone is now a bit "old" and therefore don't expect frequent updates.
Also don't ask for ETA's and if you do anyway, I'll ignore.
Q: How to fix audio stutering ?
A: Increase the PM-QOS-LIT / PM-QOS-BIG Freq in A2N app in debug menu --> "Audio" section.
Q: What is the benefit of editing the voltage table ?
A: to increase OC stability increase voltage and to decrease the device heat, decrease voltage. Last one will improve performance due to less throttling ! So it depends on your needs.
Q: How much is safe to undervolt ?
A: approx -50 mV is considered to be "safe".
Q: How to Report Bugs ?
- Please DO NOT report bugs if you are:
--- using "unsafe" Freqs
--- not using the latest release !
--- not using Samsung stock ROM (based stock ROMs are custom ROMs !)
A: Open the red A2N Kernel Control demo app and check in-app-menu (3 dots) then "Debug" and then on "logcat and dmesg" if you faced an app crash or if some features didn't work.
If the phone rebooted randomly, then tap on "last_kmsg". You will find the logs in your internal storage. After that you can attach them here in your bug report, by clicking "Attach files".

Play playstore app support only galaxy ace 2 ?
unfortunately something went wrong with the s8 app release.
need to contact Google later.
please be patient.
are u going to release a version for sm-g955f? your kernel sounds rly interesting would appreciate that.
thanks! maybe yes ... if many users want it.
G95/ g955/ f/ n？
For now it's only for G950F and only tested to work 100% stable with the CRGH Build.
Tested for very long time on my G950F.
Honestly i don't like to build software for a device i don't own .. and even not to mention to release Software without to test it on my own.
However if'll receive positive Feedback then i'll buy all S8 Variants in order to build a perfect Kernel for you Guys !
But for now lets start with this.
I'll test and update this Kernel on latest available Stock ROM...
So, stay tuned
Thank you very much, I will continue to pay attention to it. I am G955N.
I have s8+ g955f. I know that it is only for s8 but anyway, I tried to test the kernel, it is booting up but I have no touch screen. I would be more than happy to test any test build if you decide to make it for s8+ too in the future.

installed with rom deodex ambasadii deo mod v1.3 and it works perfectly, only with mtweaks I can not regulate much, especially the battery current, moreover, why is there only interactive and deadline scheduler? another interesting feature is the dex only with the cable, I have to buy it so I try it, great job, when the app comes out in the play store I try it better, now I want to test consumption.
@ace2nutzer could you send me the apk of the kernel controller in trial version on telegram, my nikname is @ pablonik79
I really cant wait to use it on s8+. Thx for your efforts #respectthedevs
G955f not available?
If the kernel I only for s8 variant it shouldn't be posted on cross device topic....I think?
But anyway, nice futures so it'll be nice to have a new alternative for both devices. There's not much development in s8/+ especially from kernel side.
Thx for your work
installed this kernel on my s8 g950fd，my sd card cant be identified
Why CRGH when latest build is CRK1(november) ?

This Kernel is optimized to work best with the Stock ROM, but it's nice to hear that it works as well with custom ROM.

Yeah that's normal it's a fully optimized custom Kernel, all features works only with the original Kernel Control App from me. Using such "Universal" Kernel Manager Apps can even make your Phone unstable and will not make things better. That's why i build for every Device // Kernel a separate Kernel Control App.
Otherwise i would build also an Universal Kernel App ... but it's not that efficient and this is what u Guys definitely don't want for sure.
moreover, why is there only interactive and deadline scheduler?

Because we only need one good working CPU Governor and I/O Scheduler ... right ?
Short and easy explanation:
Interactive: it's the perfect gov for low latency workloads. - So it's perfect for Android to have a smooth and quick response experience.
Deadline: It's optimized for Flash Devices, it's simple and stable - Also appropriate for Android.
All other Gov and I/O are unstable or will decrease the Performance and or battery lifetime ...
(at least not very appropriate for Android .... however there's also I/O sched "ROW" or "FIOPS" which would be also ok for android, but they are not that stable like "deadline" and the difference in I/O Performance isn't that much.
So i've removed them so that u Guys can't change (accidentally) this important Drivers.
when the app comes out in the play store I try it better, now I want to test consumption.

Sorry, there's no Trial Version at all ... only the Demo u can find in the Kernel Package.
But i know, u can't Tweak anything.... Please wait for the full Version.
Thank u very much Guys for your Appreciation. :good:
