Franco's mako_hotplug
*cpu-boost* (Removed currently)
Franco's enhanced interactive governor set to default (Tweaked settings thanks to Dan)
NTFS support
F2FS
INSTALLATION
1. Install zip from recovery
2. Follow the instructions, if you don't know what to do, use the pre-selected options
3. Wipe cache/dalvik cache
4. Reboot
It is recommended to disable or increase the screen timeout in TWRP recovery. If the screen timeout is enabled in TWRP, there may be a black screen after exiting the Aroma installer. This is nothing to worry about. Simply hold power and volume down and volume up buttons until it reboots. The installation will be fine. If things get stuck in aroma, simply do this reboot method and immediately hold down to get to bootloader mode, then select recovery and start from the beginning.

All compiled with latest linaro 4.9.3 prerelease toolchain and are all also packaged with anykernel method to allow for zImage and dt.img injection into rom’s stock boot.img, thus keeping ramdisk with any specific optimizations made for that exact rom. Also anykernel script now used to inject kernel settings script, formerly referred to as init script, into ramdisk to be loaded without need for init.d, and thus no need for setting selinux to permissive (Thanks Flar2).

Great info to actually read and know!
Hypernova version has all kinds of stuff that's been added from the good @franciscofranco, and the most important and amazing, IMHO, is the mako_hotplug_driver. With this, we have eliminated most governors, and now exclusively run interactive. We now also have some extra options with this interactive governor that we can set to customize the user experience smoothness, and battery life. Down below is how to work init.d scripts, which is suggested as a great set it and forget it method, but if you are trying to mess with things quickly and in user land with an app, you will have to use francos. Unfortunately, our phone is only supported by the paid version also, so looks like it's time to open the wallets and show your appreciation! Bought this personally as soon as I got the hotplug up and running. 100% worth it.
Advanced Interactive Governor Tweaks; Buttery smooth and insane battery life!
Here's some info on the pieces used from his kernel, and the app, and the guy himself it seems.
Code:
Information about the kernel
People generally change kernels for battery savings and to add features the stock one doesn't offer.
Franco's kernel has several advantages over the stock one in terms of battery saving saving features,
one of my favourite being the removal of MPdecision which in lay-mans terms changes the min and
maximum speed the CPU can run at based upon live battery temperature checks. Franco's hot plug
driver always keeps 2 cores online and always them to scale from 300mhz to 2.3ghz and based upon
load conditions will online cores 3 and 4 if required. When you touch the screen the screen the CPU
speed is boosted to approximately 1.5ghz for just over a quarter of a second and when load is reduced
the CPU speed is able to lower quickly back to lower speeds thanks to his tuned interactive
governor. Franco has created a governor for the GPU named interactive which works very much like
how the CPU equivilant does. Franco has added some newer drivers for WiFi which also helps reduce
idle battery drain while your on a busy WiFi network. Franco has also added an interface where you
can boost microphone, speaker and headphone gain levels for audio enthusiasts as well as an
interface to allow screen calibration and load pre set profiles to improve your experience with how
your display looks! There's clock speed control, voltage control, governor control, hot plug control.
You get the idea its full of cool features which can be controlled with the paid Franco.Kernel
Application (see later in the thread)

Here are some lines I've found around the interwebs as a reference for myself for some time now. All of this is set, but hey, it never hurts to learn how it all works behind the scenes.
This is not a shell script, and cannot be run as one as-is; it's just a bunch of commands. UV should never be set with init.d in case they are unstable.
These are old values, some may be good, some may not. Please ask, or do some research on what is suggested for current cpu and phones.

best min frequency:
lowest possible setting (300mhz in case of MSM8974)
i highly recommend to run those values (exept if you are actually playing demanding 3d games).
use trickster mod frequency lock feature to do so. you will experience amazing battery life.
how to get the maximum battery life:
if you have a MSM8974AB pvs 6 for example, try the following steps:
try the next higher pvs levels (pvs7). don't try AC pvs values on AB chips.
AB chips are binned for lower frequencies while AC are binned for higher frequencies (duh).
so if you have a AB chip, work your way up the AB pvs values until you have freezes or similar and move back.
if you have a AC chip, work your way up the AC pvs values etc...
if you found highest setting that does not cause any problems after intensive testing and usage:
congratulations, you did it.
how to get the maximum frequency:
first try higher than stock maximum clock and see how it behaves.
if you don't reach your desired clockspeed, try the next lower pvs setting of your chip. yes, i said LOWER.
this gives the processor more voltage to reach higher overclocks.
i don't recommend it tho since we all want our phones to last as long as possible usually.
Thank you very much to @flar2 for all his work, and assisting people like me to port it to a device that otherwise would have no such love!
Gigantic thanks to @franciscofranco for his additions, fixes, and mako_hotplug!

Oh Snap, what is going on Mass, Glad to see your kernel all over the place. Thought I was in the Sprint forums for a sec.
About time we got a new kernel.
Thanks a lot @MassStash. Will report in a bit. Gonna flash now.

Dan, how the hell you find this so fast!? lolol Thanks man, super stoked to post this one as it's such a larger footprint to see be a part of. Excited to see how much people hate it lol
PSA: this current version is made with venom ramdisk and is flashing a full boot.img with it. Because I'm old school still, spr and vzw have seen some issues with txt and calls. Pretty sure it's that, so I'm looking into using anykernel like asap so that the zImage is simply injected into which ever rom you are on. Also, when I do this, I will be able to use one download link for all variants because it is already the same exact zImage and dt.img being used as I have the unified dtb's from capt's brilliant brain. Everything should work great, just wanted to make sure I gave everyone a heads up before the complaints. Thanks a million to anyone that joins in here, and happy thanksgivin to the USA peeps!

Just a heads up dunno if it still exists but after you flash the kernel changing the frequency caused the CPU freq to stick at 300mhz not sure if Mass has worked this out or not.
So just make sure not to change freq in an app just reflash kernel and do it with in the aroma if changing causes lag this is why other than that this kernel is freaking beast

These guy's responses are usually more useful than mine haha
After flashing, I changed a few things in fauxclock and phone was extremely laggy. However, after a full reboot, everything is running buttery smooth. Will report on battery life later. Thanks again. ?

Reflash kernel and don't change the cpu freq at all in a cpu app you can only change freq in the aroma installer a little bug that needs to be worked out
Very good kernel
So far so good
Thanx for the great job
This kernel is great so far awesome work dev.

UNDERVOLTING USERSPACE
DOCs:
Stratosk - About Undervolting
Stock kernel uses a paramater boost_uV.
By default, is added in voltages but it can be disabled.
The value of boost_uV is 0 for Slow bin chips and 25000 uV = 25 mV
for Nominal, Fast and Faster.
The boost_uV may be disabled using this command:
(= undervolting by 25000 uV in Nominal, Fast and Faster)
echo n > /sys/module/acpuclock_krait/parameters/boost
3 more paramater that handle undervolting:
- lower_uV: undervolting value for lower frequencies
- higher_uV: undervolting value for higher frequencies
- higher_khz_thres: above this frequency (default 1350000KHz) higher_uV will be used.
Else lower_uV will be used.
Undervolting value is subtracted from stock voltage. The final voltage for each frequency is calulated:
Vdd(final) = Vdd(core) + boost_uV - uV
So, to undervolt frequencies 384000-1242000 by 25mV and the other frequencies by 12.5mV use these command:
echo 25000 > /sys/module/acpuclock_krait/parameters/lower_uV
echo 12500 > /sys/module/acpuclock_krait/parameters/higher_uV
The higher_khz_thres maybe changed using this command (for example to use higher_uV from 981000KHz):
echo 918000 > /sys/module/acpuclock_krait/parameters/higher_khz_thres
Debugfs file (acpuclk/acpu_table) to show the acpu table frequencies and voltages.
For example to get the information about the current status use this command:
cat /sys/kernel/debug/acpuclk/acpu_table
CPU PVS: Fast
Boost uV: 25000
Boost uV enabled: No
Higher KHZ threshold: 1350000
Lower under uV: 37500
Higher under uV: 25000

INSTALLATION
1. Install zip from recovery
2. Follow the instructions, if you don't know what to do, use the pre-selected options
3. Wipe cache/dalvik cache
4. Reboot
It is recommended to disable or increase the screen timeout in TWRP recovery. If the screen timeout is enabled in TWRP, there may be a black screen after exiting the Aroma installer. This is nothing to worry about. Simply hold power and volume down and volume up buttons until it reboots. The installation will be fine. If things get stuck in aroma, simply do this reboot method and immediately hold down to get to bootloader mode, then select recovery and start from the beginning.

NOTES AND OTHER IMPORTANT STUFF YOU SHOULD KNOW!!!
ElementalX Configuration File
Your choices in the Aroma installer are used to build a configuration file. The config file is located at /etc/elementalx.conf. You can edit this file to change kernel settings. Whatever is set in this file will take effect when the device is booted (unless other scripts or apps interfere!)
If settings are not sticking:
[*]Make sure you have busybox installed correctly and updated to the latest version
[*]Make sure the file permissions for /etc/init.d/99elementalx or 99msx are set to execute.
[*]Check to see if any /etc/init.d scripts or apps (such as Kernel Tuner or TricksterMod) are interfering with your settings.
ElementalX Log File
Every boot, a log file is created at /data/local/tmp/elementalx-kernel.log or msx-kernel.log. This file shows the date and time and all settings that have been applied. Use this to verify and troubleshoot configuration options. Also, in this file is your devices PVS number. Please refer to the links down below as to what the heck the PVS means. Helps with troubleshooting OC/voltage related reboots device specific. Not all devices were created equal!
Overclocking
Overclocking is optional. The installer lets you choose the maximum frequency. Whatever frequencies you chose in the installer will be set at boot for each CPU. Not all devices can handle overclocking. I don't recommend overclocking, this device is fast enough. If you overclock, the CPU frequency will likely be throttled due to heat. I recommend the stock frequencies, as this device is plenty fast.
CPU voltages
The installer allows you to choose from several undervolting options: stock, -15mV, -30mV, or -45mV. This only undervolts the lowest frequency, which happens to be the frequency used the most, and this is safer. Be careful, lowering voltages can cause instability.
gboost
gboost enhances gaming performance by giving a slight boost to cpu frequencies when the graphics load is high (e.g. while gaming). It should have no effect on battery life during regular usage, so it's safe to leave it enabled all the time.
fsync
fsync can be disabled if you're looking for the last ounce of performance. I recommend leaving it enabled as there is a slight risk of data loss if your phone shuts off unexpectedly before filesystems are synced.
Installing a new ROM
If you install a new ROM, it will probably replace this with the stock kernel and will definitely overwrite /etc/init.d/99elementalx and /etc/elementalx.conf so you will lose your settings and certain features. So always reinstall the kernel after installing a ROM.
Sweep2sleep
Sweep2sleep allows you to put your device to sleep by swiping right to left across the bottom of the screen where the back, home, recent buttons are. I find this useful since the stock motion gestures do not provide a good way to turn off the screen.
/sys/android_touch/sweep2wake
0= disabled
1= sweep2sleep right enabled
2= sweep2sleep left enabled
3= sweep2sleep left and right enabled
USB fastcharge
USB fastcharge is optional. This will allow you to charge at a faster rate when connected to a USB port. The default limit for USB ports is 500ma, this increases it to 1100ma. Be sure that the computer/laptop/whatever you are plugged into can handle it. Some will automatically cap it at 500ma. Please note that this does not force AC charge mode like previous implementations of force fastcharge. Your battery setting will still say USB mode. You can edit /etc/elementalx.conf to change the setting on boot.
Wake Gestures
There are three modes
Mode 1: Stock Motion Launch Gestures
For stock motion launch gestures, /sys/android_touch/wake_gestures, /sys/android_touch/sweep2wake and /sys/android_touch/doubletap2wake must all be set to 0. Enabling any of these overrides the stock gestures. Obviously Motion Launch Gestures must be enabled in the system settings.
Mode 2: Remove motion requirement
For this, you must set /sys/android_touch/wake_gestures to 1 and enable at least one gesture in /sys/android_touch/sweep2wake or /sys/android_touch/doubletap2wake and Motion Launch Gestures must be enabled in system settings. In this mode, when you sweep or doubletap, the appropriate input events are generated and acted upon the EasyAccessService (i.e., the system app that handles gesture actions).
Mode 3: Traditional S2W/DT2W
In this mode, wake gestures and actions are handled entirely by the kernel. The gestures will turn on the screen and that's it. For this, you must set /sys/android_touch/wake_gestures to 0 and enable at least one gesture in /sys/android_touch/sweep2wake or /sys/android_touch/doubletap2wake. It doesn't matter if Motion Launch Gestures is enabled or disabled in system settings, the gestures don't interact with it in this mode.
Options
For modes 2 and 3, there are several options.
Sweep2Wake
Gesture........Value
Sweep right......1
Sweep left........2
Sweep up.........4
Sweep down.....8
Add up the values for each gesture you want to enable and put the total in /sys/android_touch/sweep2wake. For example, to enable all gestures, the value is 15 (1+2+4+8). To enable sweep right, sweep left and sweep up, the value is 7 (1+2+4)
DoubleTap2wake
Set /sys/android_touch/doubletap2wake to 1 to enable DT2W, and set to 0 to disable it.
Pocket Detection
Set /sys/android_touch/pocket_detect to 1 to enable pocket detection, and set to 0 to disable it. Pocket detection is experimental right now, I'd say it's about 90% functional, but there is an occasional bug where it either doesn't work or works too well.
Vibration Strength
Haptic feedback can be enabled for the wake gestures in /sys/android_touch/vib_strength. This setting takes a number between 0 and 60. Default is 20, which is the same vibration as the stock gestures. Setting this to 0 disables haptic feedback.

CHANGELOG (Cliff-Notes) Here's a GDoc for Latest
If this is first time flashing these updated packaged kernels, please dirty or full wipe flash the rom you’re on, let it boot to system, then reboot to twrp and flash one of these kernels. Also recommneded to flash ROM’s boot.img or just dirty flash if switching between these kernels.
Feb 27, 2015 - Lollipop
All compiled with latest linaro 4.9.3 prerelease toolchain and are all also packaged with anykernel method to allow for zImage and dt.img injection into rom’s stock boot.img, thus keeping ramdisk with any specific optimizations made for that exact rom. Also anykernel script now used to inject kernel settings script, formerly referred to as init script, into ramdisk to be loaded without need for init.d, and thus no need for setting selinux to permissive (Thanks Flar2).

Infoz
Hypernova version has all kinds of stuff that's been added from the good @franciscofranco, and the most important and amazing, IMHO, is the mako_hotplug_driver. With this, we have eliminated most governors, and now exclusively run interactive. We now also have some extra options with this interactive governor that we can set to customize the user experience smoothness, and battery life. Down below is how to work init.d scripts, which is suggested as a great set it and forget it method, but if you are trying to mess with things quickly and in user land with an app, you will have to use francos. Unfortunately, our phone is only supported by the paid version also, so looks like it's time to open the wallets and show your appreciation! Bought this personally as soon as I got the hotplug up and running. 100% worth it.
Advanced Interactive Governor Tweaks; Buttery smooth and insane battery life!
Here's some info on the pieces used from his kernel, and the app, and the guy himself it seems.
Code:
Information about the kernel
People generally change kernels for battery savings and to add features the stock one doesn't offer.
Franco's kernel has several advantages over the stock one in terms of battery saving saving features,
one of my favourite being the removal of MPdecision which in lay-mans terms changes the min and
maximum speed the CPU can run at based upon live battery temperature checks. Franco's hot plug
driver always keeps 2 cores online and always them to scale from 300mhz to 2.3ghz and based upon
load conditions will online cores 3 and 4 if required. When you touch the screen the screen the CPU
speed is boosted to approximately 1.5ghz for just over a quarter of a second and when load is reduced
the CPU speed is able to lower quickly back to lower speeds thanks to his tuned interactive
governor. Franco has created a governor for the GPU named interactive which works very much like
how the CPU equivilant does. Franco has added some newer drivers for WiFi which also helps reduce
idle battery drain while your on a busy WiFi network. Franco has also added an interface where you
can boost microphone, speaker and headphone gain levels for audio enthusiasts as well as an
interface to allow screen calibration and load pre set profiles to improve your experience with how
your display looks! There's clock speed control, voltage control, governor control, hot plug control.
You get the idea its full of cool features which can be controlled with the paid Franco.Kernel

Here are some lines I've found around the interwebs as a reference for myself for some time now. All of this is set, but hey, it never hurts to learn how it all works behind the scenes.
This is not a shell script, and cannot be run as one as-is; it's just a bunch of commands. UV should never be set with init.d in case they are unstable.
These are old values, some may be good, some may not. Please ask, or do some research on what is suggested for current cpu and phones.

best min frequency:
lowest possible setting (300mhz in case of MSM8974)
i highly recommend to run those values (exept if you are actually playing demanding 3d games).
use trickster mod frequency lock feature to do so. you will experience amazing battery life.
how to get the maximum battery life:
if you have a MSM8974AB pvs 6 for example, try the following steps:
try the next higher pvs levels (pvs7). don't try AC pvs values on AB chips.
AB chips are binned for lower frequencies while AC are binned for higher frequencies (duh).
so if you have a AB chip, work your way up the AB pvs values until you have freezes or similar and move back.
if you have a AC chip, work your way up the AC pvs values etc...
if you found highest setting that does not cause any problems after intensive testing and usage:
congratulations, you did it.
how to get the maximum frequency:
first try higher than stock maximum clock and see how it behaves.
if you don't reach your desired clockspeed, try the next lower pvs setting of your chip. yes, i said LOWER.
this gives the processor more voltage to reach higher overclocks.
i don't recommend it tho since we all want our phones to last as long as possible usually.
Thank you very much to @flar2 for all his work, and assisting people like me to port it to a device that otherwise would have no such love!

holy jeebus you're fast as ****. Fully functional in the sense of using two thumbs where the second has a roll then flick up technique yes. Work like twrp recovery does, no unfortunately....

Ah, so not fully functional like on BadSeed's ROM. Got it. Thanks for the kernel and the hard work on it!
Wow praise from the Captain!
He really has been working hard on this. I don't know sh*t compared to you guys but I appreciate the contributions on here.
Don't forget the thanks button!
Finally Sprint has a custom kernel Balls to the Walls Very smooth,Stable and battery friendly plus the screen control and sound control make it all that much better

Thank you so much for your contribution!
@MassStash
I pulled the working AROMA update-binary from BadSeed's ROM so you can add to your installer for working touch.
Thanks to BadSeed team for finding a working binary!
EDIT: Attached file.
the Min CPU always jump from 300000 to 1728000 after few mins
Working great here @MassStash :good:

My only real issue is that the Motion Gestures always default to the custom settings, even if I chose the option for stock motion gestures.
On a reboot, the stock gesture behavior would work within the first minute, then default to swiping left to sleep & wake.
Other than that...this is a solid kernel.

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:
https://github.com/franciscofranco/mako/commit/34d79548cf16b69c7d0154836018e7f258a22947

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

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?

For me, As a backup when traveling international. Everyone has different reasons.

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

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 !!
