Working here on the edge. No error on synapse as well.
Great job!
Interesting for a new kernel, already tried undervolting my S7E by 25mV for everything and using battery mode for most of the stuff, very stable indeed. ASV average value of 9 over here.
Since S7E's default performance was already pretty good, so I didn't adjust the clock speed but played around with the governors and such. Still smooth performance throughout with no stutters.
I've attached my profile over here, just for those who want to try out.
Code:
[B][U]BatteryMaxV1[/U][/B] 13-6-2016
- Everything undervolt by 25mV (not sure will it reflect in the Synapse settings but please do a backup of your stock before applying.)
- Interactive with Battery Profile
- I/O 2048kb, ROW scheduler
- Enabled Gentle Fair Sleepers
- Lowered all wakelocks to 1, especially on Wlan_rx & Wlan_ctrl
- Disabled SensorHub and SSP wakelock (If you use S Health and Google Fit, turn SensorHub back on)
- Input-Booster to Battery Profile
- TCP Multi-Path Enabled, TCP Congestion to cubic, Google DNS
Other stuffs such as CPU Clock speed and stuff are basically untouched as I feel there isn't a need to really adjust it to make the phone suffer from performance issue while giving it a slight battery boost.
Code:
[B][U]BatteryMaxV2[/U][/B] (Testing phase, please report back if any errors occurs) 14-6-2016
[B] [Removed due to many complains in regards to governor causing high frequencies or lag][/B]
*TAKE NOTE! If your keyboard is crashing, use the 25mV version that I've attached below.*
- A53 4x @ 1.5GHz (smartmax), A57 4x @1.8GHz (smartmax), Exynos Hotplug Control removed.
- Undervolted everything for CPU and GPU by 50mV, others by 25mV
-UKSM Governor to low, CPU Consumption to 10%
- Disabled Gentle Fair Sleepers
- Disabled Google Play Service Fix (doesn't fix it for me, still causing drain so I turned it off, turn it on if you think there's drain for it)
- Disabled Screen Mirroring Fix (I don't use it, turn it on if you need)
- GPS Region to ASIA (remember to change to your own region)
How to use the profile?
Copy the attached file into your internal storage with a folder called "volt" and redirect to Synapse > saved_configs . Place the attached file inside and restart your Synapse. You should be able to head to your Backup/Restore tab and select it from "Selected Profile".
Feel free to tell me if anything would be better to change for the setup
Will update once kernel gets updated.
Always welcome a new kernel, will try it soon
So far so smooth and stable with minor undervolt settings, but default cpu governor is a bit hot. Great job bro!
Great work..
Will try soon..

No this kernel like all the other S7 Edge kernels do
not have a working double tap to wake feature.
Good luck,
Have a great day!
just a quick check with those who installed: how is battery or SOT? Is it better than stock?
What are the screen tweaks ? Doe it have gamma and contrast control ???
Does it have csc software disabled?

LuPuS-ARC/S-STOCK KERNEL HERE!!
LuPuS-JB-CM10/AOKP KERNEL HERE
Hi most of you already know my LuPuS-Stock kernel so thought i'd make one for you all that will work with any
cm9 based roms such as AOKP-by Supervenom and Paranoid Android, and obviously CM9 as well. Just wanna say a
big thanks to FXP - Jerpelea for pointing me in the rite direction for wifi to work
and of course the people who help me test besttt and sinkster for testing on both ARC-S and ARC
What i'm going to do is just update this by the end of the week to add everything else in.
So here is whats added so far but first it has to be done ------------

Lulzactive - Thanks to Tegrak
Based on Interactive and Smartass. When workload is greater than or equal to 60%, the governor scales up
CPU to next higher step. When workload is less than 60%, governor scales down CPU to next lower step.
When screen is off, frequency is locked to global scaling minimum frequency
Virtuous
Virtuous is a modded smartassV2 which gives even more battery time then smartassV2
Intellidemand - Thanks to faux123
This is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling,
and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such.
Intellidemand does not jump to highest frequency when screen is off.
Lazy - Thanks to Ezekeel
The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand.
Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state
on a step overriding sampling interval.
Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always
select the maximum frequency while the screen is off.
-Ondemandx:
Basically an ondemand with suspend/wake profiles. This governor is supposed to be a battery friendly ondemand. When screen is off, max frequency is capped at 500 mhz. Even though ondemand is the default governor in many kernel and is considered safe/stable, the support for ondemand/ondemandX depends on CPU capability to do fast frequency switching which are very low latency frequency transitions. I have read somewhere that the performance of ondemand/ondemandx were significantly varying for different i/o schedulers. This is not true for most of the other governors. I personally feel ondemand/ondemandx goes best with SIO I/O scheduler.
-Lionheart:
Is a conservative-based governor. The tunables (such as the thresholds and sampling rate) were changed so the governor behaves more like the performance one, at the cost of battery as the scaling is very aggressive.
To 'experience' Lionheart using conservative, try these tweaks:
sampling_rate:10000 or 20000 or 50000, whichever you feel is safer. (transition latency of the CPU is something below 10ms/10,000uS hence using 10,000 might not be safe).
up_threshold:60
down_threshold:30
freq_step:5
Lionheart goes well with deadline i/o scheduler. When it comes to smoothness (not considering battery drain), a tuned conservative delivers more as compared to a tuned ondemand.
BadAss Governor:
Badass removes all of this "fast peaking" to the max frequency. Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1024Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.
Superbad -
A "superbad" super smooth rendition of a highly optimized "smartass" governor!
Darkside -
A "slightly more agressive smart" optimized governor!
What else-----
-SLQB - (SLAB allocator with Queue)-(both)
This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate).
- Added Cleancache
- Supports ext 2,3
- Updated zRam
- Lzo compression/decompression speed has doubled on average.
- Init.d support
- Fudgeswap
- And much more
- O/C and stable upto 2ghz, although I do not recommend O/C to 2ghz for long periods of time, do so at your own risk.
Show your support for the kernel and my work by putting this in your signature, its only a quick one I done up with my limited time

Wifi modules in attachments
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Check your MD5 match the above if not re-download
Zram is not enabled by default- to enable it flash the zip below
If for whatever reason you want to disable it after you have flashed the .zip, just go to ect/init.d and delete 00zram :victory:
CIFS
The attached zip for CIFS is not a flashable zip read below
Make sure you download Cifs-v2 if your using v2 of kernel
What is CIFS???
Server Message Block (SMB) or Common Internet File System (CIFS) are normally used to provide shared access to files on a network, mostly involving computers running MS Windows.
It allows you to conveniently mount/unmount your network accessible file resources and access the files transparently via your favourite Android app (playing music / videos, accessing documents etc.) Settings are stored on your SD card with permissions to write also to your SD card.
Instructions
- extract cifsfile.zip from below
- save cifs,ko file to your sdcard
- in terminal emulator
- cd sdcard
- su
- insmod cifs.ko
Now download CifsManager or similar app and configure it

seeing how there's an overwhelming amount of governors and schedulers lol can anyone recommend a combination for bother performance and battery?
btw why is there only 341 MB of ram instead of the usual 360 MB..

Less ram because of 720p recording, was going to remove it but though people would want it, fxp have re-added it to fxp137, I can i Ilsa remove it for next release of people don't want it.
As for governors for performance I recommend intellidemand, superbad, darkside or battery life smartass, smartassv2 or virtuous. And keep SIO as scheduler it default in all my kernels

No problem, unfortunately I do not plan on making one for CM7, I've had this request for the play also. CM9 is stable so no need for cm7. I do not have time to maintain any more kernels cm 10 kernel will be out this week and that will take my.

Nice work, but androidfilehost dont work
Works fine for me
Can the op be updated to say what roms this will / won't work with? Will it work on CM11 or is it only for TW roms? Thanks!

It's for TouchWiz only
Hi @civato . Can i flash this kernel on SM-p901 ?? it's the same as SM-P900 and both of them are exynos and the only difference is that SM-P901 has sim card slot and 3G capability ! would you please compare the kernel sources of sm-p900 and sm-p901 and if they are the same , i flash it on my SM-p901 ?? Thanks.

You can always flash it, no harm will be done. However, it might be that some settings of the 3G capability is integrated in the kernel, and you will loose this. There is no verification in the kernel if you flash it on the right device. If there are any issues, just restore your stock rom.

Tip:
Use the Screen option in synapse and enable register hook & the edge enhancement and see a real sharp image.
I just flashed this latest kernel and running great, I have a question about enable register hook and edge enhancement I did this and everything looks dull / washed out is there any other settings under the screen options I need to change?
Awesome work!
Thanks for the kernel! awesome
By the way with the lastest kernel i have still experimenting some lags. Is there a way to disable the synapse tool?
This happend me constantly so ist's a bit uncorfortable when i am writing and the tablet freezec for a moment (3 seconds)
thanks in advance
Keep getting signature errors, and cannot install
Hi, I tried to install this kernel, but keep getting signature errors, and it reverts back to restore.
I wiped cache, and all, and seem to be stuck. Is there any way to make a tar file for odin? I don't have Linux , and changing the extension only corrupts it.
I would like to change the stock kernel on my smp900, as the knox counter tripped with kies, and Samsung voided my warranty for (new tablet :crying: - even sent it in and they didn't reset it, after the had admitted it was a problem)
If you can't make it a tar file for odin, what is best to use to install this?
Thanks

Can you make this kernel specifically for SM-T900? (TabPro12.2 WiFi)
I've flashed this kernel in my T900 because they're almost the same except for the Pen software and feature and every thing worked smooth and excellent but "rotation" breaks down, it doesn't work even on apps so no tilt function. Hope to hear an answer Thanks. It runs so smooth that I want some of the butter for my Behemoth Tablet lol
this should not be labelled as stable. it's the one and only kernel I've used that crashes n sometimes it will reboot while sometimes it needs to be done manually
about 3 to 5x a day on 8 to 10 hours of use a day

SM-T900 uses different hardware for screen rotation, can't make it work with this kernel.

Not having it , your problem not mine. Running 24/7 stable. At 2.1GHz and 677MHz gpu.
so before *****|ng you should probably learn how to logcat and see what is causing your problem.
so this should be labeled as stable, you on the other hand?

I have to agree with the previous poster - your experience is not typical. I have installed this kernel every time a new one is released and it gets more and more stable with every release.
You need to look at the tweaks you have made and what apps you have installed.
Asking for help and hints would be far more productive than a hit and run.

Have you considered building this kernel for the P905. Not sure if it is possible without having the specific device on-hand. Regardless, sounds like you have been able to improve performance for the P900 - congratulations on your work. Hope you have Happy Thanksgiving if you participate in turkey day activities.

LZ4 compression algorithm
LZ4 is a lossless data compression algorithm that is focused on compression and decompression speed.
The algorithm gives a slightly worse compression ratio than algorithms like gzip. However, compression speeds are several times faster than gzip while decompression speeds can be significantly faster than LZO.
The LZ4 algorithm represents the data as a series of sequences. Each sequence begins with a one byte token that is broken into two 4 bit fields. The first field represents the number of literal bytes that are to be copied to the output. The second field represents the number of bytes to copy from the already decoded output buffer (with 0 representing the minimum match length of 4 bytes). A value of 15 in either of the bitfields indicates that the length is larger and there is an extra byte of data that is to be added to the length. A value of 255 in these extra bytes indicates that yet another byte to be added. Hence arbitrary lengths are represented by a series of extra bytes containing the value 255. The string of literals comes after the token and any extra bytes needed to indicate string length. This is followed by an offset that indicates how far back in the output buffer to begin copying. The extra bytes (if any) of the match-length come at the end of the sequence.
Compression can be carried out in a stream or in blocks. Higher compression ratios can be achieved by investing more effort in finding the best matches. This results in both a smaller file and a faster decompression.

Aukhan recommended settings
F.A.Q
Can I flash this kernel on Note 4 SM-N910C or other variant?
No, you can not. This kernel is only for SM-N910F, SM-N910G, SM-N910P and SM-N910V.
When I switch to Ondemand governor I noticed that cpu-boost is disabled.
Exactly, Ondemand and cpu-boost doesn't work well together. When you switch to Ondemand governor cpu-boost will be disabled automatically. Don't re-enable cpu-boost if you are using Ondemand governor. (Synapse>CPU DRIVERS)
Which app can control this kernel?
By default, the kernel is controlled by Synapse, but you can use the app that you like (Trickster Mod, Kernel Tweaker, etc.).
I flashed the kernel and Synapse says: "No support UCI detected".
Reflash the kernel, since it was a bad installation and Synapse does not detect the scripts.
After flashing the kernel lost root what to do?
In case you loose root just flash SuperSU
Any recommended settings to follow using Synapse?
At the beginning of the second post.
After flash the kernel some apks give me FC.
Go to Google Play Store and reinstall those apks.
From where can I remove int.d script?
Go to /system/etc/init.d using any root based file manager and delete.
Note: There is an important one related to superSU and if you remove it by mistake you're gonna have trouble with root permissions.
My device doesn't show any reaction to undervolting (battery life is same as before) or gets unstable even on light undervolting?
Use DVFS disabler Module(standalone) (dynamic voltage and frequency scaling), this feature was kept in touchwiz for benchmark boosting purposes and will conflict with any undervolting and custom governors because it scales the voltages and frequency on regular intervals and is framework integrated, so gets a higher priority than kernel based voltage and scaling controls.
For people who don't know what is DVFS please refer Wikipedia.
Min/Max frequency don't stick?
If your frequency settings don’t stick, it's because on certain Qualcomm devices, there are certain system services (thermald/mpdecision/project butter) or kernel service that rewrite frequency settings based on current thermal status and/or touch input.
I made a logcat but my file is empty. How I can "fix" it?
By default Android logger is disable. Go to Synapse > MISCELLANEOUS and enable Logger Mode.
What is it PowerSuspend?
This new powersuspend PM kernel driver is a replacement for it and existing early_suspend drivers. It should give better battery life.
What is it Intelli-Plug?
Intelliplug is a replacement for mp decision. Intelli-Plug is Faux123 open source solution to Qualcomm's closed source mpdecision. Intelli-Plug is disable by default. It conflicts with mpdecsion, so is HIGHLY recommend turning off mpdecision when using intelli-plug! (If you use Synapse the change is automatic. If you enable Intelli-plug mpdecision will turn off).
What is it Intelli-Thermal?
an intelligent MSM thermal throttling kernel driver designed to replace the
closed sourced thermald(aemon) from Qualcomm.
What is it Frandom?
Frandom is a kernel random number generator, which is 10-50 times faster than what you get from /dev/urandom. And it uses very little (/dev/frandom) or none (/dev/erandom) of the kernel's entropy pool, so it is very useful for applications that require a handy source for lots of random data.
What is it CRC?
CRC is a mechanism aiming to prevent data corruption when is enabled (reduce the performance around 30%). So if you disable it improve the performance but your data can be corrupted. Use it at your risk.
/sys/module/mmc_core/parameters/crc
Do you have issues in Synapse?
Go to the Play store and install busybox on rails.
Ve a la play store e instala busybox on rails, eso arreglará cualquier fallo en Synapse.
Shealt doesn't work (FC's)
Clear data of Shealt
How to use NTFS OTG?
Install USB OTG Helper . Connect your ntfs otg then open USB OTG Helper apk click on "mount". That's it. Use your favorite xplorer to open the OTG.
Know/Reported/Fixed issues
Know issues
1. Synapse doesn't show CPU governor tunables.
I'm trying to fix it. FIXED
2. Sometimes Synapse (and others kernel control apks) show that the min frequency is 1190MHz (or other frequency).
Just cancel it. FIXED
3. Ondemand doesn't work well. FIXED
Thanks for the report @Vangelis13
4. The OTG doesn't work in r8. FIXED
Great work mate! I am sure many custom roms will use it by default!
Most value adding kernel I have ever used...

I can't even get it to boot. It show's the splash screen, then a quick glimpse of something down both sides of the screen, then goes black. It never boots. My ROM is stock with Knox and it's on removed by me with Titanium Backup, and SuperSU Beta V2.49
I can't think of any other changes.
I flashed the zip, wiped cache and dalvik and rebooted. It did not boot. So I installed the zip again, and wiped same. No go again. So then I factory reset, and tried to reboot. Nothing still. What else can I try? The instructions are pretty basic. I"m not doing anything wrong here am I? Lol

Nevermind. I was flashing 910 not 915. I was not paying attention. I thought the whole site was dedicated to our beloved Edge. My bad.
It has booted. I will play with it tonight and post my findings tomorrow. Thank you Gentlemen for your work here. I am really excited about having a permissive SELinux Kernel.

A big thank you.. Looks good now let's play..
Guys, the kernel was tested on F, G and T variant and I supposed that it's compatible with P but as I see is not.
Next is now. Powered by ET!
All running very nice.. 915f .. Thanks again ..

Yeap we could not find any P tester. Better delete it from the list until you get solid feedback.

Very nice kernel. Flashed 4 hours ago. Using it on 915G and the ROM is very responsive plus very good battery life. Thanks for long awaited custom kernel which can be tweaked by synapse.

Our device isn't supported I know a little about developing but not much, do you? If dev doesn't mind maybe we can mess with it bc I'm probably gonna just launch the device out my window at this point I got v4a to work though bud without selinux being set to permissive there's a zip on the main v4a thread go a few pages back i don't know how to post a file on here otherwise I'd just post it if u need me to pm u the file you do need init.d support (just use tx_dbs deodexed rom)

I tried flashing the 915T on my stock deodexed Tmo Edge and it booted but with a black screen. Waited a few and could hear the unlocking sound when I swiped the screen but couldn't see squat. Weird.
Lolipop or kk?

Pure, powerful and fast as hell.
These shall be the characteristics of my HellSpawn kernel for the Nexus 4 (MAKO).
Why another kernel for the Nexus 4?
Answer is simple.. why not! I started to look around for an appropriate kernel which could be an enrichment in my BeanStalk ROM (abbr. BS). One of the fastest candidates has definitely been the hells-Core kernel. But I didn't want to depend on other devs, hence I decided to start my own project based on the awesome work by hellsgod (big thanks to you!).
Your constant feedback is welcome and essential for the further development! Even if I probably cannot fulfil the wishes by everyone, I am trying to consider the most promising features requested. However, I will try to keep the number of new features limited in order to not bloat up the kernel which could easily result in a degradation of its stability.
I am looking forward to fruitful discussions with you and figuring what the hell turn out to be the most suitable kernel features in terms of performance and battery life!
Note: This kernel is compatible with Android 6.0.1 (Marshmallow) and with Android 7.x (Nougat). Please pay attention which build you are downloading. Builds for Android 7.x might be backwards compatible.

** Intellimm: fully sync w/dorimanx
** Alucard: tune for performance and to reduce idle drain. enable io is busy on alucard.
** Introduce Interactive: reduce timer with screen off (might be interesting for people who are listening music and experience audio issues due to measures for power saving while screen is off)
r11 dev notes:
I have tried many things & tested a lot of different configurations recently, e.g. to add back cpuboost driver, and also to add msm_limiter (replacement for msm_sleeper). Also worth to mention.. I have stabilized intelli_plug, which was temporarily added into r11-test-builds, but then it turned out that it has had impacts on the overall performance.. all those cool stuff didn't help to further improve this kernel, so I decided to abandon it in the official r11 build.
At this point I would like to thank two awesome guys: @dragos281993 @Cristiano Lira who supported me extremely with testing and help me on the right track! BTW, I am constantly measuring changes with help of Antutu and my own eyes..
Rumors:
Last but not least.. You might be interested in learning about how my "experiments" with lazyplug have went. Well, there is not much to say, except for it didn't work. And hence I decided to give up.

Why do I need so many different CPU governors and what are they for?
Click to expand...
Click to collapse
1: 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.
2: Performance
The performance governor locks the phone's CPU at maximum frequency.
3: Conservative
This governor biases the phone to prefer the lowest possible clockspeed as often as possible. In other words, a larger and more persistent load must be placed on the CPU before the conservative governor will be prompted to raise the CPU clockspeed. Depending on how the developer has implemented this governor, and the minimum clockspeed chosen by the user, the conservative governor can introduce choppy performance. On the other hand, it can be good for battery life.
The Conservative Governor is also frequently described as a "slow OnDemand". The original and unmodified conservative is slow and inefficient. Newer and modified versions of conservative (from some kernels) are much more responsive and are better all around for almost any use.
4: 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.
5: BadAss (has been removed in r11)
Badass removes all of this "fast peaking" to the max frequency. To trigger a frequency increase, the system must run a bit with high load, then the frequency is bumped. If that is still not enough the governor gives you full throttle. (this transition should not take longer than 1-2 seconds, depending on the load your system is experiencing)
Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu to max frequency. If the gpu is crushed under load, badass will lift the restrictions to the cpu.
6: Pegasusq
The Pegasusq is a multi-core based on the Ondemand governor and governor with integrated hot-plugging. It is quite stable and has the same battery life as Ondemand. Ongoing processes in the queue, we know that multiple processes can run simultaneously on. These processes are active in an array, which is a field called "Run Queue" queue that is ongoing, with their priority values arranged (priority will be used by the task scheduler, which then decides which process to run next).
To ensure that each process has its fair share of resources, each will run for a certain period and will eventually stop and then again placed in the queue until it is your turn again. If a program is terminated, so that others can run the program with the highest priority in the current queue is executed.
7: Smartmax
Smartmax is a mix between Ondemand and Smartassv2. It behaves mostly like Smartass with the concept of an "ideal" frequency. By default this is configured for battery saving, so this is NOT a gaming or benchmark governor! Additionally, to make it "snappy", Smartmax has "touch poke". So input events from the touchscreen will boost the cpu for a specific time to a specific frequency. Developed by XDA user Maxwen.
8: IntelliMM
A rewrite of the old Min Max governor and has 3 cpu states: Idle, UI and Max. Intelliminmax (intellimm) governor is designed to work with the newer SOCs with fixed voltage rails (ie MSM8974+ SOCs). It is designed to work within those fixed voltage ranges in order to maximize battery performance while creating a smooth UI operations. It is battery friendly and spends most of the time at lower frequencies.
9: Impulse
An improved version of interactive modified by neobuddy89. Impulse aims to have a balance between battery and performance just like interactive but has some tweaks to save battery.
10: ElementalX
The ElementalX CPU governor has been specifically designed and tuned to get the best balance between battery life and performance. By default, it is more conservative than Ondemand. During routine usage, the CPU frequency does not ramp up very often. If gboost is enabled, during gaming or any other graphics intensive situation, the CPU frequencies boost much easier in order to maintain maximum performance. There is also a built in input boost.
11: Alucard
A favourite choice and one of the original governors that Alucard_24 made. Alucard is based on ondemand but has been heavily tweaked to bring better battery life and performance. It has been known to be battery friendly without sacrificing much performance.
12: Hellsactive
A heavily modified intelliactive governor by hellsgod that has been tweaked to improve battery life. Hellsactive is less aggressive compared to intelliactive so the battery life will be more like the original interactive.
Why do I need so many different GPU governors and what are they for?
Click to expand...
Click to collapse
1: Simple
It's a new governor for the gpu frequency scaling. It will allow a more fine grained control over how the gpu scales up and down then the previous ones. Depending how you tune it, it can be better for battery life or performance.
2: Ondemand
Much like the CPU governor, Ondemand will ramp up the frequency when a load is detected. A good balance between performance and battery savings. This is a widely used governor in qualcomm devices.
3: Powersave
Like the CPU governor, this keeps your GPU running at the lowest possible frequency. Best battery life, extreme lag in games.
4: Conservative
Like the CPU governor, this one is the opposite of Interactive; it is slow to ramp up the frequency, then quickly drops the frequency once the GPU is no longer under a certain threshold of load.
5: 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.
Why do I need so many different CPU Hotplug drivers and what are they for?
Click to expand...
Click to collapse
1: MPDecision (disabled by intension -- do not even think of enabling it)
Qualcomm's default hotplugging driver. One of the most widely used hotplug drivers in all android devices.
2: Alucard-Hotplug
A great hotplugging driver by Alucard. It is known to be very battery friendly on devices.
3: Mako-Hotplug
A new popular hotplugging driver found in Francokernel. This is a highly configurable driver that can be configured to use dual core for light-loads and quad-core for heavy loads.
4: Zen-Decision
ZEN only onlines all cores when screen is on, it also takes thermal events into account and wont online any core back, if you're under 15% battery, or currently have a thermal event because of heat. So in the end it isn't a "real" hotplug driver, because it doesnt have any code for active hot plugging in it. That means you can't change its behavior.
5: Bricked Hotplug (has been temporary added, but then removed again from this kernel)
Conservative hotplug driver by showp1984. It is based on mpdecision but has been optimized for better balance between battery life and performance.
6: msm_sleeper (always on by default)
The main feature with this hotplug is that you can customize the screen off frequency. Two cores are always on, the third and fourth are independent and come online if needed. By default, if the load is over 80 for 400ms another core comes online. The third and/or fourth cores stay online as long as the load demands it or for a minimum of one second. While the screen is off, it goes down to a single core. Created by flar2.
7: AutoSMP
A highly-efficient hotplug driver by mrg666, works in-sync with the CPU governor to enable off-line cpu cores when the the CPU frequency reaches a high threshold and still more compute power is needed. Therefore, touch boost bloat is removed.
What are recommended settings for performance?
Click to expand...
Click to collapse
For a good performance you don't have to tweak anything, but use my defaults (AutoSMP/Hellsactive).
Using ElementalX as CPU governor will apply a GPU boost when GPU is at max power which should have a positive effect on gaming performance.
Using Pegasusq as CPU governor allows you to reach the highest end score in Antutu Benchmark tool.
What are recommended settings for increased battery life?

Change CPU hotplug to Alucard and CPU governor to Smartmax or Intellimm.

HKM should work as this kernel is hells-core based. It seems that HKM is no longer available in Playstore. Do you have a download link?
I don't know about UKM, I personally never used it. Could you give it a shot?
But I can tell you that it works with KernelAdiutor.
Cheers!
Another thing to flash! Really thanks for support. I will try it ASAP and give feedback.

HKM works in general.
You should not enter Display Control, otherwise FC. It's because the kernel has Franco's gamma control instead of the one by faux123.
Btw, I have added performance profiles (francescofranco). But I am not sure how to get them working. But I believe that this can be achieved with Franco's kernel manager..
Kernel is smooth. Working great with cooperation with DU10.0. Elementalx is Nice governor, no random reboots, cold and no glitches here.

These shall be the characteristics of my REVIVAL kernel for the Nexus 4 (MAKO).
Why should I use this kernel in my Nexus 4?
The "revival" kernel aims at bringing new life into your worn out NEXUS phone and is meant for those who prefer basic tweaking. This kernel will be the more conservative project, as I plan to put only the essential stuff into it like just a few governors and hotplug drivers, gamma control, UV, dt2w and some other basic stuff..
Note: This kernel is made for Android 6.0.1 (Marshmallow) and maybe later versions (who knows).
Features:
Linux 3.4.112 based on the latest sources of Semaphore kernel by Stratos Karafotis (Big thanks)
Removed lots of useless debugging and logs. Added tweaks/optimizations for increased performance. Some of the tweaks were hand-picked from kernels like Quanta-Mako (thanks zaclimon), TaUrUs_Kernel (thanks txuki2005), Unleashed (thanks ion-storm), kernel-Nexus4 (thanks motley-git), thunderzap (varunchitre15) and Mirage (thanks mgr666)
Compiled with the latest Cortex-A15 optimized UberTC 5.4.1 with some kernel based optimizations: graphite, NEON
Compatible to all Android 6.x ROMs based on AOSP and CM (incl. BeanStalk of course)
MultiROM compatible (Kexec patch)
ARM auto_hotplug (thanks thalamus; enhanced by motley) removed in r02
Alucard-hotplug (Alucard24)

msm-sleeper: upgrade to version 2 (flar2): allows to set a max screen off frequency
Linaro power oriented workqueues (thanks mrg666 & franciscofranco)
CPU Governors: ondemand (tweaked by stratosk; default), stockdemand (for those who like it stock and battery-friendly), yankdemand (a more battery-friendly derivative of ondemand), conservative, interactive (tweaked by franciscofranco), performance, userspace, powersave, elementalX (flar2), hellsactive (hellsgod), smartmax (maxwen)
GPU Governors: conservative, ondemand, performance, interactive (franciscofranco), simple (faux123)
GPU Overclocking (up to 487.5MHz) and ultra low IDLE frequency (27MHz)
IO schedulers: cfq, deadline, noop, sio, tripndroid
Customized in-kernel thermal solution smart scaling, dynamic polling, and configurable throttle temp
Gamma control by faux123 (with nougat r02) / gamma control by franciscofranco (marshmallow r03 until r08)
Dynamic management of dirty page writebacks (Christopher83)
Earlysuspend: speedup late resume (faster wakeup of the device)
Relaxed power savings from NVIDIA
Motorola MSM mcmcpy enhancements
Userspace CPU & GPU Voltage Control
Speaker Amp & Sound Control (faux123)
USB force fast charging (Chad Froebel/faux123)
DT2W/power suspend support and Touch wake (stratosk)
Exponential brightness driver (stratosk)

Partial-resume framework & quickwakeup driver
AIO optimization from Linux 3.8+ (faux123)
Tested on the following ROMs:
* Pure Nexus (AOSP)
* BeanStalk (CM-13 based)
Known issues (marshmallow release):
* Changing CPU governor to yankdemand, stockdemand or hellsactive doesn't work on latest Purity ROM, Resurrection Remix M v5.7.2, CM-13 and possibly on further CM-13 based custom ROMs. Therefore avoid those governors or your phone will freeze-in and then goes into a soft reboot.
DISCLAMER
Your warranty is now void.
I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you have any concerns about features included in this Kernel before flashing it! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.

@spezi77, can you change min GPU freq to 27MHz and include mako hotplug in next build if it isn't ask much.

I have expected that you will ask for something like mako hotplug.
I will consider it. Anyway, I have already prepared a few of the cpu governors for being used with it. I have seen quite a few variations of Franco's mako hotplug. Not sure yet, which would be the best choice.

You know me. I think the one used in Hellspawn is nice. And one thing I would like to report is that min cpu cores online setting from auto hotplug seems to not be working, at least in ka-mod.
Edit: tryed synapse and with it the situation is worse: there is not even a checkbox to activate auto hotplug.
@ spezi77 May I know the reason for another Kernel by you

1. Hellspawn is for hardcore tweakers cause it's got an insane amount of features and "Revival" has a limited amount for even better stability.
2. "Hellspawn" is based on "hellscore" while "Revival" is based on "semaphore". So they're 2 different kernels.
If you know that you'll tweak every single value of the kernel, or want to have those options there just in case, then Hellspawn is the kernel you want to use. But if you want to do some basic tweaking, "Revival" is the best for you.
Cheers !

Does kernel supported F2FS ?

No, it doesn't. But don't worry. There's no improvement using f2fs, in any department. It's placebo. The benchmarks may show slightly better results but in real world use, the phone behaves exactly the same, it gives the exact same performance and battery life. That's the reason both Stratosk and Hellsgod didn't even bother adding f2fs to their kernels.

Hum, I just had a look into the min/max cpu cores online setting. The problem does not originate from the kernel tweaker app(s). The app just reads and writes values from/into the sysfs path, and I didn't find any logical issues here. So, the min/max online cpus feature seems to be implemented in a slightly hacky way..
As of now, I have no idea how to improve this without getting a big headache.. :silly:
Simplest solution would be to ditch auto_hotplug and replace it with mako hotplug. :angel:
Edit: BTW, I did a fresh build (r02) with mako hotplug and 27MHz idle GPU freq.
Flashed today - everything looks nice and smooth so far. A think that its a little more stable and fast than HellSpawn
However I don't get all those colour profiles - where is my favourite alucard8888 and Mohit Galaxy Kehlu Mod?
I can't find the perfect colour settings
The kernel looks very nice @spezzi77. The only thing that's missing, is the gamma control from Hellspawn. The stock control doesn't really give us any tweaking options. I'm used to "Obsanity Amoled" so I can't really go without it or at least be able to tweak it the way I prefer. I'll be waiting for that to be added. Other than that, you should not add anything else cause everything is nice and stable this way.

At the moment the kernel has Stratosk's gamma control which is very close to the stock one. Franco's control is what we want for us to be able to change profiles or tweak them. I'm sure spezzi will add that in a future build.

Glad to hear that!
Oh and one more thing - dunno if anyone else noticed that/has that bug/feature
LED notification sometimes is pulsing with all rainbow colours instead of those that are set in my ROM. I remember that happening on some kernel - but right now I can't remember which one
@spezi77, I'm feeling that battery is worse in r02 in comparison with r01, I was having some good results with r01 despite using ondemand and dyn with 2 cores min but now with r02 it's not that good even using smartmax. Thanks for your commitment.

Yeah man the Beta.
Any recommendations for good balance between battery life and performance :
CPU governor
I/O scheduler
GPU governor
Max GPU 487 MHz? Not too much...
Or stay like it is...
