Special features and sysfs settings:
You can find the useful scripts in my mediafire.com.Or you can use Performance Controller App(click here for more).Th Trickster Mod which can be installed from Google Play is also works fine.
CPU voltage control VDD sys interface
This feature allows to customize the voltage assumed by each cpu scaling frequency.
It could be useful if you'd like to decrease one or more voltages for battery saving purposes (undervolting), or to increase/adjust them to prevent phone freezes (overvolting).
How to customize the voltages:
1) By downloading and using Trickster MOD or IncrediControl and changing the voltages table inside the SVS tab
2) By using customized init.d scripts (the custom values will be always restored after a reboot, if you don't format the system partition)
- Download one of the script named 01vdd_levels*
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your customized voltages, where each line has this syntax
Code:
Code:
echo "cpu_freq_HZ mV" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
cpu_freq_HZ is the cpu frequency in Hz you'd like to change
mV is the voltage you want to set
For example, the following line means that when the cpu frequency is 1516800 Hz = 1516 MHz, the voltage used will be 1175 mV
Code:
Code:
echo "1516800 1175" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
3) By using Terminal Emulator (note that the values you set will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands
Code:
Code:
su
# Run a command for each cpu frequency voltage you'd like to change
echo "cpu_freq_HZ mV" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
cpu_freq_HZ is the cpu frequency in Hz you'd like to change
mV is the voltage you want to set
For example, the following line means that when the cpu frequency is 1516800 Hz = 1516 MHz, the voltage used will be 1175 mV
Code:
Code:
echo "1516800 1175" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
Force Fast Charge
This feature allows you to force AC charging for any charger that is detected as USB (eg. PC USB ports, USB Car Chargers) and pull the full current the charger can support, in such a way as to speed up the time required for a complete battery recharge.
By enabling this feature, the USB / ADB data transfers will be disabled (security limitation to protect your data).
How to enable/disable the Force Fast Charge:
1) By directly editing the file /sys/kernel/fast_charge/force_fast_charge and setting 1 to enable the force charge, 0 to disable it (note that set value will be lost after a reboot/shutdown)
2) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to enable the force fast charge feature
Code:
Code:
su
echo 1 > /sys/kernel/fast_charge/force_fast_charge
- Then, when you want to restore the normal status, run this command to disable the force fast charge feature
Code:
Code:
su
echo 0 > /sys/kernel/fast_charge/force_fast_charge
4) By using a customized init.d script, but I don't recommend it because you have to remember to disable the feature every time you want to connect your device to a pc for data transfering after every reboot
LowMemoryKiller
The LowMemoryKiller driver is used to kill a selected process and free the memory when it is under one of the defined thresholds.
The tuning of the driver could be achieved by means of two parameters exposed by the kernel module via sysfs interface:
- /sys/module/lowmemorykiller/parameters/minfree
This file includes a comma separated array of the threshold numbers for minfree memory size (in page units).
The parameter value set for Charm-Kiss is "2048,3584,19200,23040,24320,32000".
- /sys/module/lowmemorykiller/parameters/adj
This file includes the comma separated array of oomadj factors, if the corresponding minfree threshold has been reached, one of the process with an oomadj greater than this number will be killed.
The oomadj factor is a property associated to each process, its value is in a range from -17 to +15, the processes with a higher oom_adj factor will be the first to be killed when a specific minfree threshold has been reached.
And when you type your value in,the system wll auto turn it to oom_score_adj which is from 0 to 1000.
The parameter value set for Charm-Kiss is "0,176,352,588,705,1000".
Frandom - Fast Random Generator
As Eli Billauer (the creator of this module) said, Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux built-in /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.
RAM Console
This feature is useful expecially for development and debugging purposes, when occurs kernel panic / unexpected shutdowns or reboots. Pratically, the kernel messages are also stored inside a little RAM portion and restored during reboot after a kernel panic, inside the file /proc/last_kmsg.
Dynamic FSync
This feature has been developed by Faux123 and allows to dynamically manage the synchronous writes performed on file system (FSync).
It uses asynchronous writes when the screen is on, instead of synchronous writes, to have better performance and a slightly lower battery drain, while when the screen is off the synchronous writes are re-enabled to flush all the outstanding writes and prevent possible data loss.
How to enable/disable the Dynamic FSync (default enabled):
1) By downloading and using Trickster MOD
2) By directly editing the file /sys/kernel/dyn_fsync/Dyn_fsync_active and setting 1 to enable the dynamic fsync, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic fsync feature
Code:
Code:
su
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active
- Or run this command to re-enable the dynamic fsync feature
Code:
Code:
su
echo 1 > /sys/kernel/dyn_fsync/Dyn_fsync_active
Dynamic dirty page writebacks
This feature has been developed by me and allows to dynamically manage the dirty page writebacks with two different intervals, one when the screen is on and another when the screen is off.
It is based on a commit of Francisco Franco, but instead of using hard coded values and of disabling at all the dirty page writebacks while the screen is on (possibility of data loss), I preferred to use a customizable higher dirty page writebacks interval (15 seconds) than the default one (5 seconds) while the screen is on and a customizable default interval (5 seconds) when the screen is off.
By using a higher interval we have better performance and less battery consumption, with a very low risk of data loss.
How to customize the dynamic dirty page writebacks feature (default enabled):
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), the default value is 1500 centisecs (15 seconds)
- dirty_writeback_suspend_centisecs is the interval for the dirty page writebacks when the system is suspended (screen off), the default value is 500 centisecs (5 seconds)
In my kernel builds, during boot, I set other customized values:
- an interval of 25 seconds while the screen is on
- an interval of 15 seconds when the screen is off
1) By directly editing one of the file written above inside /proc/sys/vm and setting the preferred value (note that set value will be lost after a reboot/shutdown)
2) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic dirty page writebacks feature
Code:
Code:
su
echo 0 > /proc/sys/vm/dynamic_dirty_writeback
- Or run this command to re-enable the dynamic dirty page writebacks feature
Code:
Code:
su
echo 1 > /proc/sys/vm/dynamic_dirty_writeback
- Run this command to set customize the two intervals (30 seconds while the screen is on, 10 seconds when the screen is off)
Code:
Code:
su
echo "2500" > /proc/sys/vm/dirty_writeback_active_centisecs
echo "500" > /proc/sys/vm/dirty_writeback_suspend_centisecs
Ultra-Kernel Samepage Merging(UKSM)
UKSM is more optimized and also working for single core systems. using this should give much better ram usage, but at the cost of more cpu usage.
After you reboot with our uksm enabled kernel, uksm works as a system daemon "uksmd". The main interfaces for uksmd are under
Code:
/sys/kernel/mm/uksm
How to use it ?
Uksm is smart. For most of the time, you only need to adjust cpu_governorand max_cpu_percentage for cpu consumption control.
The meaning of each file in this directory is as below:
user controllable interfaces:
run : The main control interface to stop/run.
Code:
su
echo 1 > /sys/kernel/mm/uksm/run
sleep_millisecs: how long will uksmd sleep before it wakes up and does its work.
cpu_governor: The macro governors for controlling how aggressively the uksmd uses CPU. You can do cat cpu_governor to find out the available governors and which is currently active.
Code:
[full] medium low quiet
shows that currently it works at full speed. These governors roughly stand for 90%, 50%, 20%, <1% of max CPU consumption and some pre-setting of micro-control parameters.
(NOTE: for max it means only when uksmd is working at memory areas with many many redundancy pages. For most of the time uksmd is very quiet)
max_cpu_percentage: The max CPU consumption you can further specify under some cpu governor. It's used when you are not happy with the preset values.
read-only interfaces:
<ul>
<li>full_scans: how many times uksmd sampling has covered all of your memory areas.</li>
<li>hash_strength: the current hash strength for adaptive-random-sampling hashing algorithm. The lower the faster uksmd gonna merge pages. Its range is 1 ~ 1034.</li>
<li>pages_scanned: how many pages has been scanned.</li>
<li>pages_shared: how many pages has been mapped by different page table entries, i.e. shared by different processes.</li>
<li>pages_sharing: this is roughly the number of redundant pages you have saved, with uksm.</li>
<li>sleep_times: how many times uksmd has waken up and then got sleep.</li>
<li>Since version of 0.1.1，the pages with full zeros will considered specially and seperately. You can get the information for uksmd merged zero pages by
Code:
cat /proc/meminfo | grep KsmZeroPages
</li>

Help & FAQ
THREAD RULES & PROTOCOLS FOR THIS DEVELOPMENT THREAD:
I might not have your device variant and or able to reproduce your "issue". With this in mind, without providing as much information as possible, and resetting your device to a stable unmodified baseline, any potential troubleshooting or logs could be meaningless. So please follow the guidelines set out below. Thanks
BY POSTING YOUR ISSUES IN THIS THREAD, YOU ARE AGREE TO HELP YOURSELF FIRST BY PROVIDING INFO REGARDING:
Code:
1. DEVICE MODEL ?
2. ROM and firmware version (build number, boot-loader etc) ?
3. EXACT steps taken to reproduce YOUR issue
4. Screen-shots (if applicable)
5. Did you read Posts #1-3 completely?
6. Did you search the thread, XDA or GOOGLE?
7. Did you follow the install instructions EXACTLY?
8. What was your previous kernel?
9. Do you have any other known kernel tweaking apps, scripts or mods? ([B]remove them[/B]). [COLOR="Red"]This includes Xposed etc[/COLOR]
10. Try older kernel (if available)
11. Factory reset ?
12. Try latest stock [B]UNMODIFIED[/B] firmware (without custom ROM - if you have installed) and factory reset
13. Delete your ROM BusyBox (kernel uses it's own in /sbin)
ONLY IF YOU HAVE TRIED SUGGESTIONS ABOVE:
Turn on logging in Synapse and save logs AT TIME OF ERROR. AND post together with ALL the above information.
ELSE, DON'T WASTE MY TIME, YOU WILL BE IGNORED AND/OR POST REPORTED !!
THANK YOU :good:
NO FAST CHARGE
If using the pathetic original cable, try disconnect and reconnect the USB cable whilst power is still turned on to the charger
Use a thicker / better cable, will work every time (ie. Note4 OEM cable)
CAN I BUILD A KERNEL FOR YOUR __XX DEVICE ?
I will not build for any device that I can not compile using SAME source, personally test method or debug. Some device variants can compile with same source.
Sorry. I don't have the spare time for any more variant support.
"NO UCI SUPPORT"
It's a ROM busybox compatibility issue
Three choices:
Device > settings > applications > Synapse > force close & wipe data and REBOOT
OR
Remove your ROM busybox from /system xbin and /system/bin (Synapse will use the kernel busybox in /sbin).
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
OR
Try install a different busybox
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
Synapse or BACKUP/RESTORE ISSUES
It's a ROM busybox or sqlite3 compatibility issue
Remove both your ROM busybox & sqlite3 from /system xbin and /system/bin (Synapse will use it's own from kernel /sbin).
Device > settings > applications > Synapse > force close & wipe data
Reboot or re-flash kernel as per Installation Instructions
BACKUP & RESTORE
DO NOT restore profiles from different kernel version
Refer to THIS post for "how-to" screen-shots
Refer to THIS post for a "how-to" video (thanks @aldoblaga )
LOADABLE MODULES AREN'T WORKING
Check your /system/lib/modules directory. Are any ____.ko present?
Did you flash a ROM or wipe the system partition at any point? Doing this will remove them !
Re-flash the kernel will install the modules.
If modules aren't installed after flash, then re-flash and manually mount system in recovery first.
You can check running modules in terminal with:
Code:
lsmod

F2FS SUPPORT
It's not needed. You wouldn't see any difference or measure much, if anything. Not worth the potential trade-off. This is not eMMC anymore
http://bgr.com/2015/03/17/galaxy-s6-storage-benchmarks/
STUCK ON SAMSUNG BOOT LOGO AFTER FLASH
Ensure you flashed the correct kernel for your device model
Ensure your download is not corrupted. Check MD5 hash or re-download
Your current base firmware (ROM, boot-loader version etc.) may be incompatible - UPDATE to latest with Odin and try again.
CM SUPPORT
Read Post #12
"Unauthorized actions have been detected, reboot to undo changes"
As it's a common warning found with all KNOX enabled android devices, you would have found the answer by Google search and also that it is actually unrelated to kernel and also unrelated to this kernel development..............
It is caused by the process of rooting/modifying your device. Unless you use KNOX, don't worry.
[Q] How to disable
[A] Freeze or delete your KNOX & Security related apps/processes manually (using root explorer or titanium backup (pro) or use Synapse > Security > disable KNOX
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
BATTERY TIPS
Try some (or combination) of the CPU MULTICORE features in Synapse:
HMP profile = Battery
Power Aware Scheduling (slight performance cost) = Enabled
HMP LITTLE Packing (slight performance cost) = Enabled
PEWQ (power-efficient workqueue) (slight performance cost) = Enabled
Set A57 & A53 Interactive governor profile = Battery
Set Input-Booster for key/touchkey profile = Battery
Multi-tasking: enable UKSM & "low" or "quiet" profile (slight performance/battery cost)
Set all Advanced wake-lock controls to 1, except GPS. Set it to 4
Set WiFi wakelock control to 2 or 3
PERFORMANCE TIPS
Set A57 & A53 Interactive governor profile = Performance
Set A57 & A53 Interactive governor = Turbo Mode (battery cost)
Once in a while:
Optimize Databases
FSTrim
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
Use a stock UNMODIFIED ROM for your device variant
No tweaks, Xposed or other CPU control apps installed
ASV_GROUP (ALL DEVICES ARE NOT CREATED EQUAL)
This is an example from my Exynos5420 source. Similar idea for Exynos420
http://forum.xda-developers.com/showpost.php?p=61579949&postcount=202
CAN I INCLUDE SkyHigh KERNEL IN MY ROM
Although I do appreciate your contribution here, if you could please do not include my kernel in any ROM package etc. This policy goes for anyone.
Having my kernel distributed outside my development thread just removes a lot of credit and more importantly, constructive user feedback that could be helpful to my development or user issue.
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Disable any CPU MULTICORE options in Synapse
Disable any Battery profiles in Synapse. Set to default or 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
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:

On the second post there is a change log spoiler, you can see that there's support for the F C G I variants only, nothing mentioned about T or 7, most probably won't work as these are quite different
-=-=-
The kernel performs perfectly, I'm not keen to adjust any of the settings in synapse for now, default is rock stable and smooth, battery drainage looks great as well

v2.5 released
v2.5 update for SM-G928-C / F / G / I device variants
Check out the change-log in Post #2.
NOT TESTED. I DO NOT HAVE YOU DEVICE !
XDA RULE #1 'SEARCH BEFORE POSTING". Please READ Posts #1-3 BEFORE flashing !!
Please CLEAR SYNAPSE DATA before flash: device settings > Applications > Application manager > Synapse > force stop > clear data
Have fun
Cheers

Works great on my 928F
Gesendet von meinem SM-G928F mit Tapatalk
Hello and welcome! So I started this because I hated having to have a different app to change some of the kernel settings and having init.d scripts for each kernel was a hassle to me, plus some users were having trouble with so many options available so I created this for all those who like to flash & test different kernels like me. I just ported UKM n added a things i felt most of our kernels had. A huge Thanx to @apb_axel for the awesome work.
So how this works is on every boot the script verifies all the tunable it finds specific for the kernel you have at the moment and generates the necessary files so it can be read & displayed on Synapse. Don't feel bad if you don't see all the listed options, it's just your kernel doesn't have those available.
In time I will be adding more scripts so we can have most, if not ALL tunables I can cram into. Hope you like it!

F.A.Q.
No UCI support detected? Check the following:
a) Does your ROM support init.d scripts?, IF it doesn't try this,
b) Check in /system/xbin if the uci file exists. IF it doesn't exists you can try reflashing the .zip or run the following in terminal emulator:
Code:
su
ln -s /data/UKM/uci /system/xbin/uci
c) Check the permissions of /system/xbin/uci AND /data/UKM/uci, it should be 755 or 777. IF it isn't you can try reflashing the .zip or run the following in terminal emulator:
Code:
su
chmod 755 /system/xbin/uci
chmod 755 /data/UKM/uci
d) Check the config.json file in /data/UKM/, if the file is blank you can try generating the file again with the following in terminal emulator:
Code:
su
uci reset
uci
IF NONE OF THE ABOVE WORKED FOR YOU send me a screenshot of your terminal emulator running the following command to determine your issue:
Code:
su
uci reset
uci
Some steps to fix most common issues when coming from another kernel and UKM is still installed: (thanks to gorillap)
Step 1 - go to settings>Apps>Synapse - force close - Clear data - ReOpen Synapse
If this doesn't work
Step2 - go to settings>Apps>Synapse - force close - Clear data - Uninstall Synapse. Reinstall Synapse in play store
If this doesn't work
Step3 - go to settings>Apps>Synapse - force close - Clear data - Uninstall Synapse. Delete Synapse folder. Reboot to recovery. Reflash kernel, Reflash UKM. Install Synapse
If this doesn't work, request support in thread.
To use UKM on Lollipop just do this: (Thanks to thereal_bigjake)
1) Flash Permissive boot.img (thanks to ramjet73).
2) Install SELinux Mode Changer and set to permissive.
3) Install Synapse and flash UKM v3.5 or higher (you need busybox installed also)
4) Run a terminal after boot and type su, then type \system\etc\init.d\UKM
5) Enter Synapse and profit.
To restore a profile: (Thanks to apb_axel)
1) Save the profile to the /sdcard/Synapse/saved_profiles folder.
2) Open Synapse, go to profiles tab and press the Restart Synapse button (to make to profile appear).
3) Open Synapse, go to profiles tab and select the profile, click the √ and select Restore Selected Profile.
4) At this moment Synapse will close automatically so give it a few seconds and it will open automatically again.
5) When it opens, click the X button on top, not the √.
6) Done.
Restrictions on config files: (thanks to apb_axel)
1) You can't import settings that don't exist on your current kernel (this is fairly obvious so no explanation needed).
2) Some settings that are not imported/exported for privacy concerns are: buildprop net.hostname, buildprop service.adb.tcp.port.
3) You can't import/export the SELinux status, either Enforcing or Permissive (I've read that some people had issues when restoring profiles that were based on a KitKat ROM and when it was restored on a Lollipop ROM it broke their root, they had to reinstall everything from scratch so I prefer to avoid this at all costs).
4) You can't import/export the Preferred Network Mode (again some people have complained that restoring a profile where their carries have different settings had their phone stopped working).
5) You can't import/export voltage settings (Not every CPU is build the same, so to avoid device shutdown do to low voltages this is disabled).
6) You can't import/export sound settings (This is more of a personal setting and doesn't affect battery/performance).
7) You can't import/export speaker settings (This is more of a personal setting and doesn't affect battery/performance).
8) You can't import/export gamma settings (This is more of a personal setting and doesn't affect battery/performance).
Want to integrate UKM into your ROM?: (thanks to kecinzer)

Help & FAQ
THREAD RULES & PROTOCOLS FOR THIS DEVELOPMENT THREAD:
I might not have your device variant and or able to reproduce your "issue". With this in mind, without providing as much information as possible, and resetting your device to a stable unmodified baseline, any potential troubleshooting or logs could be meaningless. So please follow the guidelines set out below. Thanks
BY POSTING YOUR ISSUES IN THIS THREAD, YOU ARE AGREE TO HELP YOURSELF FIRST BY PROVIDING INFO REGARDING:
Code:
1. DEVICE MODEL ?
2. ROM and firmware version (build number, boot-loader etc) ?
3. EXACT steps taken to reproduce YOUR issue
4. Screen-shots (if applicable)
5. Did you read Posts #1-3 completely?
6. Did you search the thread, XDA or GOOGLE?
7. Did you follow the install instructions EXACTLY?
8. What was your previous kernel?
9. Do you have any other known kernel tweaking apps, scripts or mods? ([B]remove them[/B]). [COLOR="Red"]This includes Xposed etc[/COLOR]
10. Try older kernel (if available)
11. Factory reset ?
12. Try latest stock [B]UNMODIFIED[/B] firmware (without custom ROM - if you have installed) and factory reset
13. Delete your ROM BusyBox (kernel uses it's own in /sbin)
ONLY IF YOU HAVE TRIED SUGGESTIONS ABOVE:
Turn on logging in Synapse and save logs AT TIME OF ERROR. AND post together with ALL the above information.
ELSE, DON'T WASTE MY TIME, YOU WILL BE IGNORED AND/OR POST REPORTED !!
THANK YOU :good:
NO FAST CHARGE
If using the pathetic original cable, try disconnect and reconnect the USB cable whilst power is still turned on to the charger
Use a thicker / better cable, will work every time (ie. Note4 OEM cable)
CAN I BUILD A KERNEL FOR YOUR __XX DEVICE ?
I will not build for any device that I can not compile using SAME source, personally test method or debug. Some device variants can compile with same source.
Sorry. I don't have the spare time for any more variant support.
"NO UCI SUPPORT"
It's a ROM busybox compatibility issue
Three choices:
Device > settings > applications > Synapse > force close & wipe data and REBOOT
OR
Remove your ROM busybox from /system xbin and /system/bin (Synapse will use the kernel busybox in /sbin).
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
OR
Try install a different busybox
Force stop Synapse and delete app data (device settings > applications)
Re-flash kernel as per Installation Instructions
Synapse or BACKUP/RESTORE ISSUES
It's a ROM busybox or sqlite3 compatibility issue
Remove both your ROM busybox & sqlite3 from /system xbin and /system/bin (Synapse will use it's own from kernel /sbin).
Device > settings > applications > Synapse > force close & wipe data
Reboot or re-flash kernel as per Installation Instructions
BACKUP & RESTORE
DO NOT restore profiles from different kernel version
Refer to THIS post for "how-to" screen-shots
Refer to THIS post for a "how-to" video (thanks @aldoblaga )
LOADABLE MODULES AREN'T WORKING
Check your /system/lib/modules directory. Are any ____.ko present?
Did you flash a ROM or wipe the system partition at any point? Doing this will remove them !
Re-flash the kernel will install the modules.
If modules aren't installed after flash, then re-flash and manually mount system in recovery first.
You can check running modules in terminal with:
Code:
lsmod

CPU POWER CONSUMPTION
The Samsung Exynos 7420 Deep Dive - Inside A Modern 14nm SoC (by ANANDTECH - Andrei)
F2FS SUPPORT
It's not needed. You wouldn't see any difference or measure much, if anything. Not worth the potential trade-off. This is not eMMC anymore
http://bgr.com/2015/03/17/galaxy-s6-storage-benchmarks/
STUCK ON SAMSUNG BOOT LOGO AFTER FLASH
Ensure you flashed the correct kernel for your device model
Ensure your download is not corrupted. Check MD5 hash or re-download
Your current base firmware (ROM, boot-loader version etc.) may be incompatible - UPDATE to latest with Odin and try again.
CM SUPPORT
Read Post #12
"Unauthorized actions have been detected, reboot to undo changes"
As it's a common warning found with all KNOX enabled android devices, you would have found the answer by Google search and also that it is actually unrelated to kernel and also unrelated to this kernel development..............
It is caused by the process of rooting/modifying your device. Unless you use KNOX, don't worry.
[Q] How to disable
[A] Freeze or delete your KNOX & Security related apps/processes manually (using root explorer or titanium backup (pro) or use Synapse > Security > disable KNOX
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
BATTERY TIPS
Try some (or combination) of the CPU MULTICORE features in Synapse:
HMP profile = Battery
Power Aware Scheduling (slight performance cost) = Enabled
HMP LITTLE Packing (slight performance cost) = Enabled
PEWQ (power-efficient workqueue) (slight performance cost) = Enabled
Set A57 & A53 Interactive governor profile = Battery
Set Input-Booster for key/touchkey profile = Battery
Multi-tasking: enable UKSM & "low" or "quiet" profile (slight performance/battery cost)
Set all Advanced wake-lock controls to 1, except GPS. Set it to 4
Set WiFi wakelock control to 2 or 3
PERFORMANCE TIPS
Set A57 & A53 Interactive governor profile = Performance
Set A57 & A53 Interactive governor = Turbo Mode (battery cost)
Once in a while:
Optimize Databases
FSTrim
RANDOM REBOOT
Don't UV or UC CPU or GPU
Use SkyHigh defaults
Use a stock UNMODIFIED ROM for your device variant
No tweaks, Xposed or other CPU control apps installed
ASV_GROUP (ALL DEVICES ARE NOT CREATED EQUAL)
This is an example from my Exynos5420 source. Similar idea for Exynos420
http://forum.xda-developers.com/showpost.php?p=61579949&postcount=202
CAN I INCLUDE SkyHigh KERNEL IN MY ROM
Although I do appreciate your contribution here, if you could please do not include my kernel in any ROM package etc. This policy goes for anyone.
Having my kernel distributed outside my development thread just removes a lot of credit and more importantly, constructive user feedback that could be helpful to my development or user issue.
DOWNLOAD LINK NOT WORKING
I want to keep this project all in one place - ☆☆ NO MIRRORS ☆☆
Please try again in a few minutes
POOR CPU/GPU BENCHMARK or GRAPHICS PERFORMANCE
Disable any CPU MULTICORE options in Synapse
Disable any Battery profiles in Synapse. Set to default or 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
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

Intitial release v3.9+ beta
Intitial release v3.9+ beta for SM-G928-P device
Check out the gitHub Change-log (link in Post #2).
Not personally tested > I have a SM-N920C
(If installed) Please CLEAR SYNAPSE DATA before flash: device settings > Applications > Application manager > Synapse > force stop > clear data
DO NOT restore profiles from older versions or other kernels !
XDA RULE #1 'SEARCH BEFORE POSTING". Please READ Posts #1-3 BEFORE flashing !!
BUGS:
Disabling "Turbo Mode" will screw up frequency scaling. So if you have disabled any time, you need to REBOOT !!
Changing Interactive governor profiles when Interactive is not used, will result in Synapse display errors. Nothing to worry, no need to change the profile if Interactive it not used !
Have fun

I have not personally tried it but i have read in a couple areas that it has worked. Do a little digging and you should find some answers
Hi, I found some comments, but with other ROMs, not this one. Could you let me know who said it? I would like to contact them..
Thanks!!
