ChronicKernel
* All-in-One kernel for all qualcomm variants
* Compiled with linaro
* GPU OC to 657 Mhtz (578Mhtz default - configurable though chronic-config.sh init script)
* CPU OC to 3.07 Ghtz (2.45 Ghtz default)
* CPU bandwith increase
* Added many I/O Schedulers (ROW, SIO, ZEN, etc...)
* Merged a lot of scheduler related performance patches from my S4 kernel and Faux123's
* Added CPU Governors intelliactive wheatley pegasusq smartmax dancedance nightmare intellidemand badass abyssplugv2 abyssplug and Lionheart (Default gov = interactive)
* User adjustable CPU uV
* Kernel based thermal management
* Chronic Hotplug (kernel based mpdecision replacement)
* No ROM overriding your Max freq BS
* FauxSound
* frandom support
* Enable/disable fsync support (fsync enabled by default)
* Countless amounts of ARM optimization from various sources
* Optimized and compiled with with the "Optimize a lot, or -o3 option)
* USB fast charge (disabled by default - configurable though chronic-config.sh init script
* Linux 3.4+
This kernel uses a simple shell script called chronic-config.sh (located at /system/etc/chronic-config.sh) With this script you can specify your desired default values for various things including cpu governor, min/max cpu freq. USB fastcharge etc. This file as is requires no intervention and will not interfere with any kernel tuning app you already use. It is just there for people who like a minimal approach and as it is the most direct method of changing settings so will always work. We all know how sometimes apps get an update and it breaks something for you Below is an example of the config options in the script.

July-30
* Updated to latest NG2 source from Samsung
* Updated kernel to Linux 3.4.100
July-19
* Cleaned up cpu frequency table, 2899Mhtz was never a valid freq, and the new ones were based off of that step. That is now fixed
* Bumped bandwith on 3 highest freq steps
* Bumped max voltage to 1400
* I/O: deadline: Allow 0ms deadline latency, increases the read speed
* SELinux: Fix memory leak upon loading policy
* msm: kgsl: Fix nice level for higher priority GPU start thread, previously we were using the lowest possible process priority which increase latency, (cherry-picked from flar2's HTC One-M8 kernel)
* PM: devfreq: Use high priority workqueue. Same thing as mentioned above, give the GPU freq driver higher priority (flar2)
* A couple misc. I/O related patches from upstream CAF kernel
* Updated to latest NF6 kernel source from Samsung
* removed more log span (ktoonsez)
* added nightmare cpu governor
* tweaked some ancient configs for intellidemand back from the msm8x60 days
* added frandom support if there is anyone who uses it
* Added sysfs module to enable/disable fsync (enabled by default). It's in the standard location (/sys/module/sync/parameters/fsync_enabled) and like always can be configured though the chronic-config.sh script. I can also personally vouch for the tack that tricksterMOD will show the FSYNC enable/disable toggle with this patch. So any other app with the option should as well
* cleaned up chronic-config.sh and added missing cpu governors to list
July-17
* Added ability to overclock CPU to 3.01Ghtz
July-13
* Chronic Hotplug is born! This is basically based off of ktoonz KT auto hotplug but with user configurable parameters. Right now all you can change is the "enable_core_thresholds" this is the load the system has to be at for each respective core to turn online. the number is % of cpu load time 10. So 30% would be 300 (0 = always online). There is one module called enable_core_thresholds that sets all four cores. Its formatted like this (0 240 290 390). I have added an option in the chronic-config.sh script to configure this. Here is an example showing cores 0 and 3 always being on and 1 and 2 to come on at 24% and 29% respectively
Code:
ENABLE_CORE_THRES="0 240 290 0"
This line can be found in chronic-config.sh under the "Chronic Hotplug" section. Check script or above for more info.
* Disabled userspace mpdecision since we are now using Chronic Hotplug
* Also added option to set I/O scheduler in chronic-config.sh
* Backported some upstream 3.16 scheduler updates
July-10
* Reverted some of the sched tweaks merged from faux's kernel to vastly improve I/O performance
* Disabled some more debug options we don't need to speed up the kernel
* Switched back to Gzip compression as we have the room and kernel will initialize faster
* Set net loopback default mtu to 64K
* Fixed simple-ondemand gpu governor from crashing (ktoonsez)
* Reverted DRIVERS: SLIMBUS initial overclock commit as it seemed to drain battery when playing music
* Removed async-fsync for now until I make a module for it. Like another user said, I didn't notice any performance decrease with it off.
* Removed F2FS as i'm pretty sure its only compatible with AOSP (If i'm wrong let me know and i'll merge it back)
* Further tweaks to thermal (kthermal) values to be more stable on high frequencies (dropped polling speed to 500 ms and lowered temp limits about 2 degrees
* Disabled KT-auto-hotplug code i forgot about since I don't support it
* Stopped Samsung's "cpufreq_limit" driver from overriding Max freq (note: I had the option of stopping it from changing the min freq but it drastically decreases performance. This is equal to the cpu-boost and DVFS driver on the S4. They just expanded it to include a max freq cap which i disabled so we are not limited by it, So bottom line. You can set your min freq/ but it is temporarily overridden by the driver at times. THIS IS NORMAL AND IS LIKE THIS IN ALL KERNELS EXCEPT I ACTUALLY DISABLED THE MAX LIMIT SO IT STOPS GETTING LIMITED AT 1.19GHTZ AT TIMES. THIS IS THE OPTIMUM SOLUTION
* Fised chronic-config.sh not copying to the devices
* chronic-config.sh: fixed path for GPU max freq
* Set GPU min freq to 320mhtz (Samsung default) and added an option in chronic-config.sh to change it
* chronic-config.sh: list all available cpu frequencies instead of just a range since they are hard to remember
July-5
* initial release *
Some noteworthy changes from original source not listed above...
* Got rid of some logspan.
* send input events one at a time (faster touchboost related responses)
* few mismatch derps by samsung (faux123)
* Few other small fixes
* ]If you have problems with frequencies sticking use "System Tuner" and go to Settings and prevent other apps from changing CPU settings
* ]If you have problems with MINIMUM frequency sticking the reason is because of the touch boost driver. when you tap the screen you can't go below 1.19Ghtz, hence whenever you set a min freq....The only real solution to this without disabling the touch boost driver which hinders performance is to use the chronic-config.sh script or have an app set it boot. basically be set without a tap on the screen
* Although this kernel has now reached "beta" status. bugs still could pop up. please if you find a reproducible bug and decide to post please try and provide a last_kmesg or logcat.

Thx for this kernel! Everything works great except one thing...the min frequency doesn't stick @ 300 mhz. I have this problem on all kernels I tried. I tried your advice with no frills cpu but unfortunately it doesn't helps it even set it to 300 mhz!

Yeah. its suppose to be like that. there is a cpu-boost driver written by samsung in the kernel that does that. To test i disabled part of the code that played with min freq but it really gives you a performance hit. so yeah. dont bother with min freq. Its suppose to change like that. its basically another mpdecision service in the background. ktoonz kernel has it. faux's has it. stock kernel has it. just the way it is on the msm8974pro

not sure about no frills but using system tuner it will eventually reset to what you set
As the GPU is so much overclocked, is there any GPU governor similar to the CPU ones?
I assume the phone temporarily underclock the GPU if it's not needed to save battery, am I right?
And BTW I think the config file has a typo.
# GOV+smartmax
Should be
# GOV=smartmax
Right?

It was stupid. I just was wondering why you were teasing us 900A owners with a kernel we can't have due to our locked bootloader and then I realized I was in the unified section.
Sorry about that.
Does this kernel include all features from original Ktoonse kernel?
I noticed Ktoonse TW kernel zip file is several megabytes bigger then this one.
Chronic-config.sh is not in system/etc. Do we make it our self's? Thanks for kernel btw

Any idea on stability with a S5 active sm g870a. And if so will Tegrak overclock run with this kernel.

Is the SELinux status set to permissive by any chance? if so that would be fantastic!

hmmm. it should be. never actually checked to see if it copied over. is it present in the zip file?
EDIT: just realized i compiled the build with my "dev" script that doesnt include the zip. I'm gonna be releasnig a new version soon (NO ETA!!!!) when i do i'll pop the script in there. everything in it you could configure with an app anyways. I just like it because its set on boot always and faster

not entirely. the size is because of XZ compression. but I did remove some of the extra cpu throttling things. like GPS governor or music playing min freq etc since i dont support his app. But other then that yes..

You are in the galaxy s5 section. It will probably not work for the s5 active

Reason I ask is I've heard people flashing stuff from your guys section and only losing the active button which other than the fingerprint scanner is really the only big difference and also s5 active doesn't have its own forum so I have to post here with you guys. Hopefully we will have our own forum soon. EDIT: duh locked bootloader here never mind

albinoman887 - Thank you for this kernel! Only thing missing from Ktoonsez was -fsync support and you rectified the issue.
Update
One issue I have found, flashing the kernel breaks init.d, for some reason it deletes 'system/bin/sysinit'.
Also I guess I wrongly assumed that the HTC fsync was the same as standard -fsync disabling, for one the module isn't there and there is not any bandwidth increase that one would see if -fsync was disabled. Can you add support for it? The issues with it and data loss are greatly exaggerated and it doesn't have to be enabled by default. Thank you, so far the kernel is running great.

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
Ooh, was waiting for it. Gonna try that as soon as I get to office (home PC doesn't recognize fastboot mode :-\)

All drivers are in place, and I can use Flash mode, but when I connect in fastboot mode (blue led) Flashtool says "phone connected in flash mode" and fastboot itself complains that there are no connected devices.

Reinstalled flashtool recently, got that error, reinstalled the drivers one by one and it worked. For further help (from those that i'm sure know better than me) go to the flashtool sticky thread.

because your rom has the last modules from fxp kernel perhaps the signal is no so good do the follow

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

Left it overnight, 3g on, sync on, bad ass/noop. Battery drained 11% over 10 hours, which is great compared to any cm9 previously.
Someone tried this on Arc S with the cm9 wi-fi problem (getting ip address loop)?

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. Kernels to 10, I simply don't have the time, and besides I'll get in Trouble with the missus.......sorry

cm9.1 cm10 roms use kernels from 431 firmware dont use people baseband 77 only 72 with that roms.....if kernel changed we need other baseband
GOAL
The goal of this kernel is to have a central place for developers in the community, who don't want the burden to maintain their own kernel, to have a place to do so. Many times, developers who work on these devices constantly develop issues with others or don't have time to incorporate new features. Our goal is to avoid all that. Anything and everything will be accepted, granted it doesn't break anything. @show-p1984 has been kind enough to not only host the source but grant the use of his buildbot for this project. Every time source is pushed, the bot will start to build the kernel, zip up the package and finally upload it to my goo.im account. If you'd like to become part of this project then go ahead and reach out to me on twitter (@jassycliq) or PM me on here. My short term goal for this kernel is to add all the hotplug drivers available for mako and incorporate them into this one kernel. As it stands we can only use Qcom's binary, show's mpdecision and faux123's intelli-plug as they have switches to turn them off. These can be changed on the fly, as long as the user turns off all the hotplug drivers first then turns on the desired hotplug method. I'd also like to have an app that can control this, well a proper application to be exact.

Choosing between the 3 hotplug drivers
This kernel comes with 3 hotplug drivers (intelli-plug, qcoms mpdecision and kernel based mpdecision) by default only Qualcomm's MPDecision is used. To turn one of the others you must use their respective sysfs interfaces after turning off the one's you're not using. To make it easier for you, I have included a small little application that helps you turn through this. If you'd like to make an init.d script to choose which one you want on boot then use the following commands
For kernel based mpdecision
Code:
echo "0/1" > /sys/kernel/msm_mpdecision/conf/enabled
echo "0/1" > /sys/kernel/msm_mpdecision/conf/scroff_single_core
For Intelli-Plug
Code:
echo "0/1" > /sys/module/intelli_plug/parameters/intelli_plug_active
echo "0/1" > /sys/module/intelli_plug/parameters/eco_mode_active
For Qualcomm's MPDecision
Code:
start mpdecision
stop mpdecision

Why do I have no WLAN?
Due to this kernels very high optimization settings it is too big for our boot.img with WLAN included into the kernel, so it is built as a module. That means it needs to be inserted into the kernel upon boot up, which needs to be automated for maximum comfort = userinit (init.d) support.
The zip adds init.d support to your ramdisk, if that fails for some reason the wlan module cannot be inserted.
if
Code:
adb shell lsmod
doesn't show this:
Code:
tun 14701 0 - Live 0x00000000
cifs 275399 0 - Live 0x00000000
wlan 2964650 0 - Live 0x00000000 (C)
Then init.d support is probably missing.
You can test it by going to /system/etc/init.d/ and executing 00wlan.
Code:
adb shell
su
. /system/etc/init.d/00wlan
Wait a few seconds and try to enable wifi and repeat the above lsmod command (should now show wlan, you can execute 01cifs and 02tun too).
If WLAN now works, init.d support is missing.
You need to have busybox installed in order to be able to get init.d support going, this shouldn't be a problem for most people, since it is usually installed when rooting your phone anyway.
It does not matter if busybox is installed in /system/bin or /system/xbin, my script will detect the location upon flashing and patch the ramdisk accordingly.
If no busybox is found, the script will add init.d support to your ramdisk with the default location: /system/xbin/busybox. All you need to do is install busybox there and reboot your phone.

No, but as it stands right now nothing has changed that would be broken. In the future the test folder should be treated like a nightly build and the master folder should be treated like a stable build.
BTW I'm running the first one on that folder. The only change the newest one had is that it fixes an error where mpdecision was renamed, but now that we default to that, we don't want that to happen.

Check OP, it goes over this.
Since the kernel is highly optimized WiFi, TUN, and CIFS need to be built as modules. Because of this, we use init.d scripts to load them at boot, this requires busybox. You can check if it loaded by typing the following in terminal:
lsmod
If it doesn't say WLAN, then the WiFi module needs to be loaded manually by typing this in terminal:
su
./system/etc/init.d/00wlan
If that works then try updating your busybox it might have an issue. Also if you have another init.d that starts with 00 change the wlan to 08wlan

Compare the features of the two of them and see . This one seems to be more feature filled while his Bricked builds are more stability.
Also check the git's of both.

About time you released this Been reading all your tweets lately.
This looks awesome! Just a quick question because I'm a junkie for optimizations:
Will this include the various performance improvements from Franco's Franco Kernel, Morfic's Trinity Kernel, and the super fast CodeFireX MakoKangBang kernel? Also, I myself would recommend compiling it with CodeFireX's 4.8.1 Linaro Tool chain with back ports from the 4.9 Tool chain.
Can't wait to see how this turns out! Keep up the awesome work!

On stock LL with the kernel no issues so far.
Something I've noticed though is that overall performance seems better on LL but graphics seems to be suffering since KK.

I'm assuming your referring to LL kernel in general. Both SkyHigh and stock ?
BTW: Been working on/adapting some more Synapse tweaks and tricks....

Ya, I don't mean your kernel is sluggish in any way.
I've just noticed that LL is overall performing better in day to day tasks, but the graphics performance seems to have dipped significantly since KK and benchmarks definitely reflect it.
I just thought maybe you had an insight as to why that is or if you and other users are having the same observation as I am.

Not really much I can do except for a little refining.
I have been privately told of an effort to port the newer GPU drivers from S6. That might help........... I wish him the best in his effort. Otherwise wait on firmware and source updates (which could be a while).
I haven't benchmarked LL in any format, I'm just enjoying the general UI fluidity that should have been there in KK !!

thanks UITA ,again for sharing.please excuse me as i am new ,i share the same expereince here that the graphic is very sluggish,to flip between apps is very fast but to open them it is more slow compare with kk, am i rigjt to say its problem with the rom and is there a way to trigger the 64bit in our exynos.thanks

Yes, our device is more than capable for 64bit, but in my opinion, Samsung will never do it. Why, because to keep the majority Qualcomm customers happy as SD805 is technically a far INFERIOR SoC.
Our device would require firmware with 64bit libs, bootloader, and kernel. The kernel has an option to compile 64bit, but unfortunately Samsung need to release the firmware. It's a pity they have effectively neutered some potential of our device....
BTW. have you tried disabling force GPU rendering for 2D in Developer options? I just leave mine as is for testing purpose.
Look for a update v1.3_beta tonight.
I just don't have time to refine/test properly before heading away for a bit .........
EDIT: Will be a little longer than expected, just getting my head around cortexbrain, been a couple years

I will bubble wrap this reply and try to make it one of my nicer ones. ........
If you could please read Posts #1-3 you will see Exynos S-K-L plastered everywhere, including the thread title, requirements etc etc. If you do flash on anything other than this, you will BRICK your shiny new Note Edge-F !!
v1.3b released
SkyHigh Note Edge Exynos LL kernel v1.3b is now publically released.
Please read & follow the INSTALLATION INSTRUCTIONS to ensure a trouble-free kernel !
** If Synapse gives an "apply/discard" bug after resuming display, then;
press cancel [X] !! (DO NOT APPLY)
close/open Synapse , or
don't leave Synapse displayed (on screen) when screen turns off
* Don't worry, Synapse has just detected some sleep settings (from cortexbrain). Those vaules will change back automatically to screen on values if you follow the advice above !!

BUG: A53 Cores are limited to stock max freq (1300 MHz). I do know the error, so will fix it on Friday 1st May
HI opp .. I know you don't like to compile for devices you don't have but could you point me in the right direction to compile straight unmodded download of the 915f kernel .. it complains of missing driver file fc???? when I do make clean ..
Thanks in adavance

No, Exynos source and defconfig are not the same as Qualcomm. Same can be said for setup of our build environments.
v1.4 released
SkyHigh Note Edge Exynos LL kernel v1.4 is now publically released (for my few thankful supporters)
Please read & follow the INSTALLATION INSTRUCTIONS to ensure a trouble-free kernel !
If you are tired of (DVFS or) kernel PM over-riding your synapse A57 frequency settings after your display has resumed, then this version will prevent that using cortexbrain screen on/off functions !!

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.
Features:
Linux 3.4.112 based on sources of hells-Core N4 kernel b88-M (hats off to hellsgod) and tweaks from other kernels, e.g. Quanta-Mako (thanks zaclimon), TaUrUs_Kernel (thanks txuki2005), Unleashed (thanks ion-storm) and Mirage (thanks mgr666)
Compiled with the latest Cortex-A15 optimized UberTC 5.x with some kernel based optimizations: graphite, NEON
AOSP/BeanStalk/CM compatible
MultiROM compatible (Kexec patch)
Alucard-hotplug (alucard)
AutoSMP-hotplug (Mgr666) set as default
dyn_hotplug (stratosk)
Mako-hotplug (franciscofranco)
msm-sleeper: upgrade to version 2 (thanks flar2)
Zen Decision Hotplug (bbedward)
CPU Governors: hellsactive (default), conservative, ondemand (tweaked by stratosk), interactive (tweaks from neobuddy and franciscofranco), performance, elementalX (flar2), pegasusQ (ByungChang Cha), alucard (alucard), smartmax (maxwen), intelliminmax (faux123)
GPU Governors: ondemand, performance, simple, conservative
GPU Overclocking up to 487.5MHz
Bricked thermal driver (showp1984)
Gamma control by faux123
Userspace Voltage Control (faux123)

Exponential brightness driver (stratosk)
USB-OTG Support (ziddey/faux123)
Marshmallow: Support for android-keyboard-gadget (You can use your device as a keyboard/mouse for your PC) (zaclimon)
Knob for Fsync on/off (franciscofranco)
Knobs for Arch Power and Gentle Fair Sleepers
Knobs for preventing wakeups: bluesleep wakelock, bluedroid_timer wakelock, wlan wakelocks and msm_hsic_host wakelock
Qualcomm Slimbus driver incl. tweaks
Partial-resume framework & quickwakeup driver
No F2FS support (don't ask me for adding it)
Tested on the following ROMs:
* Pure Nexus M/N (AOSP)
* BeanStalk M (CM-13 based)
* Resurrection Remix M (CM-13-based)
* [NMF26O] Fake nexus rom for Nexus 4
* NeXus4ever ROM N (AOSP)
Known issues:
* According to a user report it doesn't appear to work on latest Chroma.
* Changing CPU governors doesn't work in CM-based ROMS
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.

3. Wipe cache/dalvik cache again (optional)
4. Reboot system
IMPORTANT NOTE:
With r05 and higher, you don't have to worry about clean and/or dirty flashing problems. The anykernel installer will reuse the ramdisk of your previous kernel and apply a patch with my HellSpawn Kernel Tweaks.

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.

It's meant to be used ONLY with fake nexus rom, because it is the only rom with the modifications to use CPUSET properly. As a result, using it with another rom will result in one core being used only.

Click to expand...
Click to collapse
Tc 5.x and 6.x are the most up-to-date and stable toolchains provided by UBER devs. Tc 7.0 was temporarily in use (experimental).
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?
Click to expand...
Click to collapse
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

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)
USB-OTG Support (ziddey/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.

r07 (2016-08-12)
Addresses all of the r06 test (2016-08-06) changes as well as the following:
* Security update: Fix CVE-2016-5340 (Quadrooter Vulnerability)
* Compiled with -03
* Add CPU governor: yankdemand (a more battery-friendly derivative of ondemand)
* Add GPU governor: simple (faux123)
* Updated the kernel installer script to reduce logcat spam (powerhal) and to disable mpdecision / thermald
r08 (2016-08-14)
Addresses all of the r07 changes as well as the following:
* Rebased the kernel in order to leave faulty stuff behind as quite a few changes were in contradiction to battery-life and fluidness
* Added Improved framebuffer imageblit function
* Add toggle to control software CRC
* Here is a quick overview of what has been left behind: Linaro-power efficient wq, timer upstream updates and smp related updates)
r01 for nougat (2016-10-08)
* Initial AOSP compatible release with focus on Android 7.x (even though previous builds already worked in nougat ROMs)
* Remove toggleable software crc (potential reason for data loss and reboots)
* Set default i/o scheduler to NOOP for smoother boot animation and an increased overall performance
* Set max readahead value to 256KB (Fair enough for a bit more performance without sacrificing latency)
* Reintroduce Linaro-power efficient wq from Kernel 3.10 (directly picked from franciscofranco's hammerhead kernel)
* Add Latest Version of Alucard HotPlug (allows for energy savings)
* mako_hotplug: don't use an unbound wq (reverted a few things to better cope with our mako)
* mako_hotplug: use more accurately fitting defaults for mako (default CPU freq unplug limit: 1242MHz / default load_threshold: 70% for a slightly increased performance boost)
* cpufreq: interactive: remove hispeed_freq init restriction. How dare you to force me not to 'disable' hispeed_freq? (Thanks franciscofranco)
* DT2W: fire a small vibration when device is woken up (Ported from franciscofranco's shamu kernel)
r02 for nougat (2016-10-09)
* Replace franco's gamma control with the one by faux123
* Remove CPU governors being incompatible with this kernel (hellsactive, stockdemand, yankdemand)
* Introduce intelliactive CPU governor by faux123

Kernel tweaks illustrated
In order to use the tweaks included into this kernel, you can use:
1. KernelAdiutor-Mod (updated 2016/11/20):
--> My personal build which allows to select the semaphore dt2w profiles (exclusive feature not yet supported in the build by David 617)
--> KA-Mod build by David 617 which will provide the latest updates at some point in time
2. or install Synapse.
@spezi77, can you change min GPU freq to 27MHz and include mako hotplug in next build if it isn't ask much.
Btw, phone is smoother than ever now. Thanks, bro!

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...
