ISSUES
DO NOT POST ANY BUG REPORTS REGARDING SOD, FREEZE or REBOOT WHERE YOU (USER) HAS CHANGED ANY VOLTAGE OR FREQUENCY FROM DEFAULT !!
Uninstall any CPU control apps, tweaks and scripts etc.
Install Wanam DVFS disabler for greater kernel control
Flash kernel
Boot and allow things to stabilize
Open Synapse & tap :
"understood" message about unstable boot
"select all globally"
"undo" button
"apply"
make any change
"apply"
Reboot and ensure "synapse boot completed" toast message
You should be good to go
BOOT-LOOP
Power off & let device cool
Wipe cache & dalvik-cache in recovery (if custom recovery)
Re-flash kernel
Re-boot
Let things stabilize and cool before touching anything
BETTER BATTERY LIFE
There are no best settings. User "HABIT" is #1 cause of battery drain, followed by screen, ROM & apps, modem etc
This kernel is built to be balanced with a good mix of battery whilst keeping performance
Decrease screen brightness
Use dark wallpapers and app themes
Check your wakelocks with better battery stats app & use Greenify app to stop unwanted apps self starting and running in the background
Suggest:
CPU GOV: governor = ondemand (tweaked for power efficient workqueues)
CPU FREQ: 200 > 1900 MHz (-25 mV for all)
Synapse: CPU MULTICORE: Hotplug CPU UP boost = 30 %
GPU: 100 > 480 MHz (-50 mV for all) (100 MHz may induce some GUI sluggishness)
GPU: Midgard Power policy control = coarse_demand
GPU: Midgard Power policy threshold control = Battery (may induce some GUI sluggishness)
PowerSuspend Driver = Enable
MEMORY: Dynamic FSync = Enable
MEMORY: Dirty Page Writeback = Enable
CPU Multicore Power Saving = (2) Agressive
BETTER PERFORMANCE
DO NOT POST ANY BUG REPORTS REGARDING SOD, FREEZE or REBOOT WHERE YOU (USER) HAS CHANGED ANY VOLATGE OR FREQUENCY FROM DEFAULT !!
Disable DVFS with [APP][Android 4.0+][DVFS Disabler]
Warmer device under heavy load, but within the safe CPU temp of 95 degC
Synapse: CPU FREQ: 500 > 2000 MHz (2100 not stable for some devices)
Synapse: CPU MULTICORE: Power Efficient WQ = disabled
Synapse: CPU GOV: use Interactve governor
Synapse: GPU: set Midgard Power policy threshold profile to Ondemand or Performance. This will scale your GPU up/down faster at the expensive of battery life compared to Battery profile.
Synapse: GPU: GPU max freq = 533 MHz (more if your device is stable)
Synapse: MEMORY: UKSM = enabled
Synapse: ADVANCED: LMK profile = aggressive
GPU THESHOLD CONTROL
Set Midgard Power policy threshold profile (This determine how your GPU freq scales up/down):
Battery = battery friendly
Ondemand = Good all-round mix
Performance = A little agressive
Method:
Ensure you apply [] any changes to MIN / MAX GPU freq or GPU GOV Threshold profile
PRESS THE "Apply GPU GOV SETTINGS" button !!
Settings will be applied immediately and auto set on every boot.
HOW TO BACKUP YOUR STOCK KERNEL BEFORE FLASHING SkyHigh KERNEL
Boot into TWRP Recovery
Select Backup
Select "[X] Boot" only (boot.img/kernel)
Select Storage > Micro SD (if external sdcard installed) > OK
Swipe to backup
CAN I USE OTHER KERNEL CONTROL APPS
No, many features and options won't be available. Remove all other control apps to avoid conflicts !
Synapse is the recommended and has everything you need
HOW TO MONITOR LIVE CPU & GPU VALUES
CPU load & freq - available RAM - GPU freq - CPU temp - most resource intensive process
[APP][2.1+] Cool Tool
Download my personal cooltool_presets > unzip & copy folder to INTERNAL sdcard. If you have cool tool app already running, you must disable > overwrite existing folder > enable
LITTLE CORE CPU FREQUENCY
Real frequency is apparently double that reported by other apps
Example: min 200 MHz (real) in Synapse is reported as 100 MHz in SetCPU
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place (Thanks to XDA) - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
HIGH CPU/GPU OC >> excessive heat >> thermal throttling >> reduced clock frequency >> DECREASE PERFORMANCE
DO NOT KILL PROCESSES
This feature allows the user to define processes and system processes white-lists filled with the preferred process names and to not be killed by lowmemorykiller, unless it is absolutely necessary.
When a the lowmemorykiller needs to free ram, it will first kill the processes not included inside the two process name lists chosen by the user.
If there are no more standard killable processes, then it will be necessary to kill one of the processes included inside one of the two white-lists, to prevent system hangs, slowdowns, etc.
You can find the [SkyHigh/Synapse] folder on your internal sdcard and add one process name per line. Lists updated on reboot.
Max 25 processes
Example only:
Code:
com.ea.games_r3_row
com.quoord.tapatalkxdapre.activity
DYNAMIC MANAGEMENT OF DIRTY PAGE WRITEBACKS
* [Christopher83]
This feature allows to have two different intervals for dirty page
writebacks and to dynamically manage them when the system has been
resumed (it's active) or when has been suspended.
Three new procfs parameters are exposed inside /proc/sys/vm path:
- dynamic_dirty_writeback is the activation status of this feature,
set 1 to enable it, set 0 to disable it and use the standard behaviour
- dirty_writeback_active_centisecs is the interval for the dirty page
writebacks when the system is active (screen on)
- dirty_writeback_suspend_centisecs is the interval for the dirty page
writebacks when the system is suspended (screen off)
This feature is in part inspired on Francisco Franco's patch:

BACKUP & RESTORE
If the backup isn't visible, reboot device and ensure for have "synapse boot completed" message. Otherwise synapse won't read the file.
Reboot after applying your new settings
Read "ISSUES" & "SYNAPSE BOOT CANCELLED" above
TCP/IP NETWORK SECURITY
* Thanks to zeppelinrox & V6SuperCharger
Hardening the TCP/IP stack to SYN attack
Bump up tw_buckets in case we get DoS'd
Ignore pings
Don't cache connection metrics from previous connection
Don't pass traffic between networks or act as a router
Enable spoofing protection (turn on reverse packet filtering)
Don't accept source routing
Don't accept redirects

SEGMENTATION FAULT
I don't believe it's kernel related, but rather busybox
Try uninstall your ROM busybox with this app. https://play.google.com/store/apps/details?id=stericson.busybox and reboot.
Re-flash kernel
Use the busybox that comes with the kernel located in /sbin
Also try to update your SuperSu and su binary if it asks and reboot.
USB KEYBOARD / MOUSE
Base project: https://github.com/pelya/android-keyboard-gadget
Required app: USB KEYBOARD
For best results, enable & use Hacker's Keyboard
Steps:
Ensure device USB debugging
Connect device to system via USB cable
Enable in Synapse > USB > USB Keyboard / Mouse >> Enable & apply
Start USB KEYBOARD app
BATTERY SCALING CALIBRATION - FUEL GAUGE RESET
Tap [Fuel-Gauge reset] in synapse BATTERY section
Reboot device
Battery % "reporting" calibration (digital)
a) Deplete battery to 5-10% (NOT ZERO)
b) Charge UNINTERUPTED until FULL (don't touch)
c) Unplug and then use normally. Device should then re-calibrate itself

True. Another tab s 10.5 here. Hope to see the 10.5 one soon.
Have CPU OC to 2.1 GHz & UC to 200 MHz (read as 100 in most CPU control apps) working for next release.

Oh, the device model. I'm waiting for LTE version, but now I can see, it's been released in Europe.
Actually, I was expecting it will come with new Wolfson DAC 5110, but it seems to have the previous one - 5102, same as SGS4. Still not bad.

Was released here in
Phuket, Thailand last Thursday. Was hoping for a snapdragon 32GB but ended up with a 16 GB Exynos. A snapdragon 805 would have been sweet, but i think they might release with the 800........ A few other things they could have updated too. But for the most, i really like it.

I don't see why people pay a premium for an LTE MODEL when you can just tether it to the LTE on your phone without an extra contract?

** I WILL NOT BUILD FOR ANY DEVICES THAT I CAN NOT PERSONALLY TEST & DEBUG. DON'T ASK, BECAUSE YOU WILL BE IGNORED !! I DON'T USE A SNAPDRAGON DEVICE .... **.
Let get it straight, I am not a real Developer, but I am UpInTheAir, former part time kernel “hack” of SM-T700/705/T800/805, SM-N9005 LTE, SGT 7.7 JB & ICS Kernels. I now share with you my Exynos 5433 TW SM-N915 S-K-L kernel compiled & modified from official Samsung sources.
* I don't pretend to know everything, so if you can be constructive and help out this project, please do so. You will find allot of answers by searching gitHub, XDA and GOOGLE Just like I do …......

HELP & FAQ
"SYNAPSE BOOT CANCELLED"
Wait for the kernel to stabilize and device to cool
Open synapse app
Synapse app menu > select all globally > undo > apply ✔
Re-boot
If still issues > try again after #1 (and make any small change and save-reboot)
Still issues > Manually set config after boot (open synapse app > synapse app menu > settings > disable apply on boot)
ISSUES
Uninstall any CPU control apps, tweaks and scripts etc.
Install Wanam DVFS disabler for greater kernel control
Flash kernel
Boot and allow things to stabilize
Open Synapse & tap :
"understood" message about unstable boot
"select all globally"
"undo" button
"apply" ✔
Reboot and ensure "synapse boot completed" toast message
You should be good to go
BOOT-LOOP
Power off & let device cool
Wipe cache & dalvik-cache in recovery (if custom recovery)
Re-flash kernel
Re-boot
Let things stabilize and cool before touching anything
BETTER BATTERY LIFE
There are no best settings. User "HABIT" is #1 cause of battery drain, followed by screen, ROM & apps, modem etc
This kernel is built to be balanced with a good mix of battery whilst keeping performance
Decrease screen brightness
Use dark wallpapers and app themes
Check your wakelocks with better battery stats app & use Greenify app to stop unwanted apps self starting and running in the background
Suggest:
CPU governor = ondemand
CPU big Cores: 500-1900 MHz (changes not always sticking - needs more testing)
CPU LITTLE Cores: 200-1300 MHz
Power Efficient Workques = enabled
IO Scheduler = FIOPS
BETTER PERFORMANCE
Disable DVFS with [APP][Android 4.0+][DVFS Disabler]
Warmer device under heavy load, but within the safe CPU temp limits
CAN I USE OTHER KERNEL CONTROL APPS
No, many features and options won't be available. Remove all other control apps to avoid conflicts !
Other apps aren't yet compatible with HMP and allow adjustments to LITTLE Core frequencies only.
Synapse is the recommended and has everything you need
RANDOM REBOOT
Don't UC CPU big.LITTLE cores
Don't UC CPU with power saver mode enabled
Use SkyHigh defaults
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place (Thanks to XDA) - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Allow the device to cool. Repetitive testing will heat the device hardware and invoke thermal throttling and lead to decreased benchmark.
HIGH CPU/GPU OC >> excessive heat >> thermal throttling >> reduced clock frequency >> DECREASE PERFORMANCE
WHAT ARE SYSCTRL, GOVERNOR, SCHEDULER ETC
Do yourself a favour and Google it.
If you still don't know, don't bother with it
BACKUP & RESTORE
If the backup isn't visible, reboot device and ensure for have "synapse boot completed" message. Otherwise synapse won't read the file.
Reboot after applying your new settings
Read "ISSUES" & "SYNAPSE BOOT CANCELLED" above
TCP/IP NETWORK SECURITY
* Thanks to zeppelinrox & V6SuperCharger
Hardening the TCP/IP stack to SYN attack
Bump up tw_buckets in case we get DoS'd
Ignore pings
Don't cache connection metrics from previous connection
Don't pass traffic between networks or act as a router
Enable spoofing protection (turn on reverse packet filtering)
Don't accept source routing
Don't accept redirects

SEGMENTATION FAULT
I don't believe it's kernel related, but rather busybox
Try uninstall your ROM busybox with this app. https://play.google.com/store/apps/details?id=stericson.busybox and reboot.
Re-flash kernel
Use the busybox that comes with the kernel located in /sbin
Also try to update your SuperSu and su binary if it asks and reboot.
PC CANNOT SEE DEVICE WHEN CONNECTED BY USB CABLE
Enable USB de-bugging in Developer options
Switch to MTP in Synapse app & apply
Re-connect device to PC and allow any drivers to install
DO NOT KILL PROCESSES
This feature allows the user to define processes and system processes white-lists filled with the preferred process names and to not be killed by lowmemorykiller, unless it is absolutely necessary.
When a the lowmemorykiller needs to free ram, it will first kill the processes not included inside the two process name lists chosen by the user.
If there are no more standard killable processes, then it will be necessary to kill one of the processes included inside one of the two white-lists, to prevent system hangs, slowdowns, etc.
You can find the [SkyHigh/Synapse] folder on your internal sdcard and add one process name per line. Lists updated on reboot.
Max 25 processes
Example only:
Code:
com.ea.games_r3_row
com.quoord.tapatalkxdapre.activity
USB KEYBOARD / MOUSE
Base project: https://github.com/pelya/android-keyboard-gadget
Required app: USB KEYBOARD
For best results, enable & use Hacker's Keyboard
Steps:
Have appropriate device USB drivers installed on PC
Connect device to system via USB cable
Enable in Synapse > USB > USB_Keyboard-Mouse >> Enable & apply
Start USB KEYBOARD app
..
Bugs / Known Issues
BUGS / KNOWN ISSUES
Some A57 CPU Freq settings might "revert"
Probably due to Samsung DVFS, try disabling it
If unstable boot refer to FAQ & HELP
POWERSAVE MODE REBOOT
Is not actually caused by the kernel. If you have Wanam DVFS disabler active, you must disable, reboot, and then enable Power Save Mode.
or
Under-clock CPU freq manually instead
or
You can still use Power Save Mode: Restrict performance > CPU performance > UNCHECK
** I don't know of any other "fix" or work-around.
AUDIO: Headphone amplification doesn't work
I forgot to remove it from Synapse settings. (Won't work until AndreiLux or other capable Dev fixes it)
ALL CPU GOV (EXCEPT INTERACTIVE) AFFECT ONLY THE LITTLE CORES
Might be as designed by Samsung
Need to check if same on stock kernel

SM-N915P Sprint Galaxy Note Edge
If you feel like it, here's the recovery.img for the Sprint CDMA variant. I just posted this in the Chainfire thread and hopefully there'll be a root soon. Or if there isn't one by next weekend, I'll screw with it and try to make one.
FWIW: Flashing the CF Note 4 root is a great way to mess up your phone and not get root.

First user post isn't even OT.......
Sorry, i won't anymore mess with firmware/source I can't directly test "method" for myself. I don't have the time or motivation either.
If root didn't work, was in the middle of tryjng to create a root kernel. Knox and SELinux don't play nice with it. If you're willing to risk, and know how to recover, no big deal. I've created a 1000 ROM and kernel etc for flash, there is always the chance (mainly of corrupted flash) one day.....

My apologies.... I provided the recovery.img in hopes you might be interested in building your kernel for it.... *not* for rooting support. I must have been having a bad communication day yesterday
I brought up the root bit as an attempt to let it be know that root for the P was imminent, which is a requirement for your kernel.
If you aren't interested in building a kernel for this, I may be, if you would let me port yours. I haven't worked much with building Android kernels, but I write embedded software and have rolled my own linux for various devices in the process. I'm guessing they might be similar processes

This is a new device and new hardware. Much of the kernel patches and custom drivers require to be written from the ground up. I'm not capable to do that, whilst I'm capable to modify and adjust certain things, that what seperates a hack from a real good dev such as @AndreiLux. I did try adapt his sound control, but the main speaker gain wasn't working, the headphones equaliser were though. I haven't bothered progressing with it.

INSTALLATION
Backup your original boot.img [BOOT] in CWM recovery (or better to backup everything)
Uninstall any CPU control apps, tweaks and scripts etc.
Recommend: Disable or remove KNOX (you can disable with Synapse once kernel is flashed)
Install Synapse app from Google Play and rate it ☆☆☆☆☆ !!
Disconnect device from PC USB
Device settings > developer options > enable USB debugging
If flashing from previous SkyHigh kernel > Force Stop Synapse app > clear data
Flash SkyHigh kernel in CWM recovery
NOTE: Updater script will auto wipe cache & dalvik-cache directories on flash - required for ART optimization. Be patient, first boot will take a while.

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

* 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

Thanks .. I'll take a look only requested your help as the code base is likely shared across by versions of the phone and hence likely you hit a similar issue .. but the link is welcome cheers

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 !!
Cheers,

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.

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...

Anybody on sm-n915p get their data running if I can't figure this out I'm about to just clean install ROM or Odin lollipop update and flash but major thanks for this wonderful creation
Thanks so much!
One zip file covers all those models of the Edge? Nice work.

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)

This only for LolliPop and above?
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?

great to see more devs are interested to start using the redmi note 3!
btw, about thunderplug, specifically the 2nd hotplug style(sched mode?), is it any different compared to the usual behaviou(without hotplug)? i'm a bit confused with this hotplug, and can't find any info on the internet.
