[KERNEL] [SM-N9005 HLTE] [03 July] SkyHigh TW Kernel [v3.3]
THIS PROJECT IS NOW ABANDONED DUE TO MY OTHER COMMITMENTS FOR FAMILY, WORK & OTHER DEVICES IN XDA. THERE IS JUST NOT ENOUGH TIME IN THE DAY. SEE YOU ALL AROUND XDA & HAPPY MODDING !!
N9005 HLTE TW supported only. (No S5 ROM port. Newer ROMs based on NFx firmware may not be compatible )
I don't have time to build and debug for other variant devices I can't test or a ROM I don't use - sorry.
Let get it straight, I am not a real Developer, but I am UpInTheAir, former part time kernel “hack” of SGT 7.7 JB & ICS Kernels. I now share with you my first SELinux TW N9005 LTE Kernel compiled 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 SEARCH Just like I do …......

"WHAT ARE THE BEST SETTINGS FOR 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
Some extra tips to increase battery life without UV:
Synapse:
- Max screen OFF scaling freqency = 652 MHz
- Touch boost high freq = 1574 MHz
- Touch boost low freq = 960 MHz
- Intelli-Hotplug = enable
- Intelli-Hotplug Profile = Eco-Conservative > Eco-Performance > Conservative > Balanced > Performance
- Intelli-Hotplug Touch Boost = Disabled (may cause slight lag if disabled)
- sched_mc_power_savings = 2:Aggressive
- Gentle fair sleepers = enabled
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
INTELLI_PLUG PROFILES
Max cores in use:
Eco-Conservative = 2
Eco-Performance = 2
Conservative = 4
Balanced = 4
Performance = 4
CAN I USE OTHER KERNEL CONTROL APPS
No, many features and options won't be available.
This is due to the implementation of the CPU HARD LIMIT Userspace DVFS lock.
Synapse is the recommended and has everything you need
WHAT IS THE USERSPACE DVFS LOCK
If set to 1 or 2, userspace_dvfs_lock will prevent userspace (ROM as well as any APP, including CPU controlling apps) to change CPU min/max, that is normal and intended !.
* 0 = allow changes to scaling min/max.
* 1 = ignore (don't apply, but don't return an error).
* 2 = refuse (don't apply, return EINVAL).
Post # 192
RANDOM REBOOT
Don't UV
If using custom CPU governor > set Userspace DVFS lock to 0
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
TCP/IP NETWORK SECURITY
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
- Further reading:
http://www.cyberciti.biz/faq/linux-kernel-etcsysctl-conf-security-hardening
http://www.symantec.com/connect/articles/hardening-tcpip-stack-syn-attacks
AnTuTu CRASHES WITH CPU OC
If OC CPU > set Userspace DVFS lock to 0
Don't OC too much
Don't UV
Try increase voltage to higher frequencies
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 [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.tapatalkxda.pre.activity
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
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
..
Great. Another kernel is coming to note 3
Good! I attended the link of download!
Thanks so much! !

v1.0 is released. Please read Posts #1-3 before flashing.
I'll post initial changelog somewhere in due course, but time to get working on v1.1
Reminds me, I'll post a disclaimer...........
Edit: I'll upload a flashable stock boot.img
finally after your awesome kernel back then in 7.7...congrat and tq for this kernel

Your welcome. :good:
Big thanks to the real devs here and hard-working forum members that also contribute to the various features and commits etc !
More to come of this simple kernel yet But don't expect it to be full works. I can only do my best with my limited knowledge and the time I can afford. I just see it as a challenge and share accordingly. Also big thanks to @civato with many of his initial commits and base synapse config.
Cheers,

Screenshots
Added some screenshots :good:
Doesn't cover all options, but users should get the idea
Next release, user will be able to set CPU voltage for individual frequency (as in screenshot). I've kept the Global CPU voltage control in case user prefer that.
Baby steps...........

If you're going to post in development section with a percieved "bug", please in future give full details allowing to replicate.
Reflashed v1.0 & tested with Antutu GPU test. GPU OC - works fine. It scales to 550 MHz if load requires. If you want to lock the frequency, set the min to the same as max.
Edit: I use cool tool app to observe "live" frequencies during testing etc
Edit 2: I believe (could be wrong. Need time to study code) that the GPU may have thermal limiting, reducing frequency under high temp, just like the CPU. This would also be normal.

I just checked and all is good.
I like to keep this project in one place. Great idea by XDA.
Please try again, sometimes the XDA is a little "finicky" to UL, so maybe same for DL too. Refresh your page and try again :good:
I have to go away for a few days, I have plenty of ideas and additions for next release. Until return......

Thanks. The kernel is still a "work in progress", and trying to keep it stable but with a number of mods and exposed configurable options.
I'm still not sure if I'll add any custom governors or schedulers, easy to do but the stability of stock is great. Maybe intellidemand though?
I'm away for a few days, so I will try and add some info into post 3 and synapse as I progress with further builds when I return home.
Wifi - use cubic or Westwood plus. Edit: Maybe I'll look at adding option to use Google dns server, tcp speed tweaks etc from V6SuperCharger.
Personally, I haven't yet had to tweak the LMK minfree values on Note 3 (unlike my Galaxy Tab 7.7 with 1GB RAM and multi-window mod). It's just got so much RAM and great multi-tasker. I haven't got around to playing with entropy values either. A lot of tunable values are just exposed so if user "wants" or "needs" to tweak, it's there anyway.
There is a lot of info on the Internet that can explain things better than I ever will or pretend to understand. In that case 99/100 times I leave the values at stock.
My personal value for randomize VA space =0. Supposedly helps with GUI smoothness. ..... Somethings are hard to tell or placebo.
I've got lots of things on the "to do list", Enjoy v1.3 and beyond

This is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling,
and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such.
Intellidemand does not jump to highest frequency when screen is off.
Lazy - Thanks to Ezekeel
The Idea here is to eliminate any instabilities caused by fast frequency switching by ondemand.
Lazy governor polls more often than ondemand, but changes frequency only after completing min_time_state
on a step overriding sampling interval.
Lazy also has a screenoff_maxfreq parameter which when enabled will cause the governor to always
select the maximum frequency while the screen is off.
Lulzactive - Thanks to Tegrak
Based on Interactive and Smartass. When workload is greater than or equal to 60%, the governor scales up
CPU to next higher step. When workload is less than 60%, governor scales down CPU to next lower step.
When screen is off, frequency is locked to global scaling minimum frequency
- Superbad
- a "superbad" super smooth rendition of a highly optimized "smartass" governor!
- Darkside
- a "slightly more agressive smart" optimized governor!
-Ondemandx:
Basically an ondemand with suspend/wake profiles. This governor is supposed to be a battery friendly ondemand. When screen is off, max frequency is capped at 500 mhz. Even though ondemand is the default governor in many kernel and is considered safe/stable, the support for ondemand/ondemandX depends on CPU capability to do fast frequency switching which are very low latency frequency transitions. I have read somewhere that the performance of ondemand/ondemandx were significantly varying for different i/o schedulers. This is not true for most of the other governors. I personally feel ondemand/ondemandx goes best with SIO I/O scheduler.
-Lionheart:
Is a conservative-based governor. The tunables (such as the thresholds and sampling rate) were changed so the governor behaves more like the performance one, at the cost of battery as the scaling is very aggressive.
To 'experience' Lionheart using conservative, try these tweaks:
sampling_rate:10000 or 20000 or 50000, whichever you feel is safer. (transition latency of the CPU is something below 10ms/10,000uS hence using 10,000 might not be safe).
up_threshold:60
down_threshold:30
freq_step:5
Lionheart goes well with deadline i/o scheduler. When it comes to smoothness (not considering battery drain), a tuned conservative delivers more as compared to a tuned ondemand.
BadAss Governor:
Badass removes all of this "fast peaking" to the max frequency. Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1024Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.
-Virtuous
Virtuous is a modded smartassV2 which gives even more battery time then smartassV2
Added Io-scheduler --
VR io-scheduler - Unlike other schedulers, synchronous and asynchronous requests are not treated separately,
instead a deadline is imposed for fairness. The next request to be served is based on it's distance from last request.
- SIO - Simple IO-Scheduler-
SIO is the default scheduler in this kernel. It is widely-regarded as the best all-round performing IO scheduler for android. It is low on CPU usage and optimized for flash-based storage. From the creator - "Based on Noop, Deadline and V(R) IO schedulers. This algorithm does not do any kind of sorting, as it is aimed for aleatory access devices, but it does some basic merging. We try to keep minimum overhead to achieve low latencies. Asynchronous and synchronous requests are not treated separately, but we rely on deadlines to ensure fairness."
- BFQ - Budget Fair Queueing IO-Scheduler-
From Creators

* Licensed under the GPL-2 as detailed in the accompanying COPYING.BFQ file.
*
* BFQ is a proportional share disk scheduling algorithm based on the
* slice-by-slice service scheme of CFQ. But BFQ assigns budgets,
* measured in number of sectors, to tasks instead of time slices.
* The disk is not granted to the active task for a given time slice,
* but until it has exahusted its assigned budget. This change from
* the time to the service domain allows BFQ to distribute the disk
* bandwidth among tasks as desired, without any distortion due to
* ZBR, workload fluctuations or other factors. BFQ uses an ad hoc
* internal scheduler, called B-WF2Q+, to schedule tasks according to
* their budgets. Thanks to this accurate scheduler, BFQ can afford
* to assign high budgets to disk-bound non-seeky tasks (to boost the
* throughput), and yet guarantee low latencies to interactive and
* soft real-time applications.

VM tweaks (explained below)
VM Tweaks
dirty ratio and dirty background ratio 1 & 2
This controls how often the kernel writes data to "disk" (in our case the internal microSD system card, not the removable microSD card). When your apps write data to disk, Linux actually doesn't write the data out to the disk right away, it actually writes the stuff to system memory and the kernel handles when and how the data is actually going to be flushed to the disk. These values represent a percentage, the higher the percentage, the longer it waits to flush, the lower the percentage, the more often flushes will occur. Now remember, we are dealing with solid state storage, not the traditional disk platter and spindle. So we are actually able to delay flushes a little longer with solid state versus a traditional hard drive disk.
dirty_expire_centisecs
How old "dirty" data should be before the kernel considers it old enough to be written to disk. It is expressed in 100ths of a second.
dirty_writeback_centisecs
This is the interval of when the writeback daemons periodically wake up and write "old" data out to disk. It is expressed in 100ths of a second.
min free kbytes
This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a pages_min value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size. Default is 2048kb.
overcommit_memory
This controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.
0 - Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slighly more memory in this mode. This is the default.
1 - Always overcommit. Appropriate for some scientific applications.
2 - Don't overcommit. The total address space commit for the system is not permitted to exceed swap plus a configurable percentage (default is 50) of physical RAM. Depending on the percentage you use, in most situations this means a process will not be killed while attempting to use already-allocated memory but will receive errors on memory allocation as appropriate.
Swappiness
A property for the Linux kernel that changes the balance between swapping out runtime memory, as opposed to dropping pages from the system page cache. Swappiness can be set to values between 0 and 100 inclusive. A low value means the kernel will try to avoid swapping as much as possible where a higher value instead will make the kernel aggressively try to use swap space.
VFS Cache Pressure
File system cache (dentry/inode) is really more important than the block cache above in dirty ratio and dirty background ratio, so we really want the kernel to use up much more of the RAM for file system cache, this will increas the performance of the system without sacrificing performance at the application level. The default value is 100, as a percentage, and what you want to do is lower the value to tell the kernel to favor the file system cache and not drop them aggressively.

- zRam is not enabled by default unless on CM10 ROM, for AOKP to enable it flash the wedgess-zram-enabler.zip in CWM
- If for whatever reason you want to disable Zram after you have flashed the .zip, just go to ect/init.d and delete 00zram
People will ask so i'll just post it here---------to check if zRam is enabled go to terminal emulator or similar and type
Code:
free
or alternatively
Code:
cat /proc/swaps
Also added CIFS support....
What is CIFS???
Server Message Block (SMB) or Common Internet File System (CIFS) are normally used to provide shared access to files on a network, mostly involving computers running MS Windows.
It allows you to conveniently mount/unmount your network accessible file resources and access the files transparently via your favourite Android app (playing music / videos, accessing documents etc.) Settings are stored on your SD card with permissions to write also to your SD card.
Now download CifsManager or similar app and configure it
Please Click Thanks :good:

Thanks to the testers :highfive:
it's just awesome
tnx a lot wedgess
Ok, am trying it, the performance is 5% smaller than that of M66B kernel, battery life need to test further, will see tomorrow and post results. Thanks a lot to wedges and welcome to the forum .
One request i would have though: Could you add the 24 MHz frequency its wonderful for battery life, and in combination with smartassV2 it doesn't compromise performance at all.
Long rebooting (stuck) from Power Menus, I need to press Camera Key to continue
Normally reboot if I execute it from Terminal
^^^ that is a known bug.
The performance (on gaming)is lower than Fxp kernel (only a bit)
But battery saving is very good.

Lulzactive - Thanks to Tegrak
Based on Interactive and Smartass. When workload is greater than or equal to 60%, the governor scales up
CPU to next higher step. When workload is less than 60%, governor scales down CPU to next lower step.
When screen is off, frequency is locked to global scaling minimum frequency

select the maximum frequency while the screen is off.
-Ondemandx:
Basically an ondemand with suspend/wake profiles. This governor is supposed to be a battery friendly ondemand. When screen is off, max frequency is capped at 500 mhz. Even though ondemand is the default governor in many kernel and is considered safe/stable, the support for ondemand/ondemandX depends on CPU capability to do fast frequency switching which are very low latency frequency transitions. I have read somewhere that the performance of ondemand/ondemandx were significantly varying for different i/o schedulers. This is not true for most of the other governors. I personally feel ondemand/ondemandx goes best with SIO I/O scheduler.
-Lionheart:
Is a conservative-based governor. The tunables (such as the thresholds and sampling rate) were changed so the governor behaves more like the performance one, at the cost of battery as the scaling is very aggressive.
To 'experience' Lionheart using conservative, try these tweaks:
sampling_rate:10000 or 20000 or 50000, whichever you feel is safer. (transition latency of the CPU is something below 10ms/10,000uS hence using 10,000 might not be safe).
up_threshold:60
down_threshold:30
freq_step:5
Lionheart goes well with deadline i/o scheduler. When it comes to smoothness (not considering battery drain), a tuned conservative delivers more as compared to a tuned ondemand.
BadAss Governor:
Badass removes all of this "fast peaking" to the max frequency. Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1024Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.
Superbad -
A "superbad" super smooth rendition of a highly optimized "smartass" governor!
Darkside -
A "slightly more agressive smart" optimized governor!
What else-----
-SLQB - (SLAB allocator with Queue)-(both)
This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate).
- Added Cleancache
- Supports ext 2,3
- Updated zRam
- Lzo compression/decompression speed has doubled on average.
- Init.d support
- Fudgeswap
- And much more
- O/C and stable upto 2ghz, although I do not recommend O/C to 2ghz for long periods of time, do so at your own risk.

This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a pages_min value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size. Default is 2048kb.
overcommit_memory
This controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.
0 - Heuristic overcommit handling. Obvious overcommits of address space are refused. Used for a typical system. It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage. root is allowed to allocate slighly more memory in this mode. This is the default.
1 - Always overcommit. Appropriate for some scientific applications.
2 - Don't overcommit. The total address space commit for the system is not permitted to exceed swap plus a configurable percentage (default is 50) of physical RAM. Depending on the percentage you use, in most situations this means a process will not be killed while attempting to use already-allocated memory but will receive errors on memory allocation as appropriate.
Swappiness
A property for the Linux kernel that changes the balance between swapping out runtime memory, as opposed to dropping pages from the system page cache. Swappiness can be set to values between 0 and 100 inclusive. A low value means the kernel will try to avoid swapping as much as possible where a higher value instead will make the kernel aggressively try to use swap space.
VFS Cache Pressure
File system cache (dentry/inode) is really more important than the block cache above in dirty ratio and dirty background ratio, so we really want the kernel to use up much more of the RAM for file system cache, this will increas the performance of the system without sacrificing performance at the application level. The default value is 100, as a percentage, and what you want to do is lower the value to tell the kernel to favor the file system cache and not drop them aggressively.

Thanks that you did it. You can try to enable V-Sync in kernel and see if uers are happy. I did it on sirkays kernel and some games become fc. But it depends on many things. So make a version with Vsync enabled.(VERTICAL Sync. Thats teh main thing that Project butter uses among with egl confings and gpu cpy hardware syncs)

Doomlord recovery. (5.0.2.7)
Which schedulers and Governors should i choose for battery life？:laugh:
Can you atlease make this kernel atlease 1.7Ghz I'll accept the risk
this kernel is great i test with antutu score 4935 with no OC
I wish I could be TWRP as Recovery haha

why not add VR to IO-schedulers.........
@wedgess
Great kernel
One request, can you please include pre-rooting for ics .587 in your next version ?
what is the best setting of governor and IO-scheduler to get better life battery on this kernel ?
what about voltages? have undervolt in the kernel?
cifs can not supprort utf8

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

VM tweaks (explained below)
VM Tweaks
dirty ratio and dirty background ratio 1 & 2
This controls how often the kernel writes data to "disk" (in our case the internal microSD system card, not the removable microSD card). When your apps write data to disk, Linux actually doesn't write the data out to the disk right away, it actually writes the stuff to system memory and the kernel handles when and how the data is actually going to be flushed to the disk. These values represent a percentage, the higher the percentage, the longer it waits to flush, the lower the percentage, the more often flushes will occur. Now remember, we are dealing with solid state storage, not the traditional disk platter and spindle. So we are actually able to delay flushes a little longer with solid state versus a traditional hard drive disk.
dirty_expire_centisecs
How old "dirty" data should be before the kernel considers it old enough to be written to disk. It is expressed in 100ths of a second.
dirty_writeback_centisecs
This is the interval of when the writeback daemons periodically wake up and write "old" data out to disk. It is expressed in 100ths of a second.
min free kbytes
This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a pages_min value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size. Default is 2048kb.

Tested! Play GB Rom booting fine, but it stuck on landscape
GSM Working, Wifi working fine! Camera working (720p working)
Sound is fine
So. everything is perfect, just now it is fixed to landscape mode
@wedgess
May u put this code in defconfig to fix landscape and display problem

Thanks but unfortunately the above is no use as it display kernel console message. Only needed for testing before boot. Think I may have fixed it. Will post a test under this post when ready.
If it works I'll fix up 480p version and few other changes. Then add to OP so quicker the better for you guys

Watch >>> THIS <<<
FOR BUG REPORTING: Stock UNMODIFIED TouchWiz (TW) 5.1.1 ROM (this means no Xposed or tweaks etc)
Custom recovery i.e.. TWRP
INSTALLATION
If you have systemless root installed, then you must REMOVE it as this kernel will auto-root a proven and stable 2.52 binary into system.
Open SuperSU app
Select "Full unroot" option
Reboot (or flash kernel)
Re-install SuperSU app
Uninstall any CPU control apps, tweaks and init.d 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 ☆☆☆☆☆ !!
Device Settings:
Enable Developer Options > OEM UNLOCK
If flashing from any custom kernel with Synapse app > Device settings > Applications > Synapse > Force Stop > clear data
If not installed > Install SuperSU from Google Play:
N9200/N9208: unlock your bootloader >> Install and run CROM service unlock app from Galaxy App Store (this will probably wipe your accounts). If you have problems with CROM, try without it !
Boot into custom recovery and flash SkyHigh_kernel____.zip FOR YOUR DEVICE and reboot
After boot:
a) wait at least 120 secs to stabilize
b) Open Synapse
c) Tap "Understood"
d) DO this step so some defaults are set !!
1. tap the square menu button top right hand corner
2. tap the three dots button
3. "select all globally"
4. tap the back button next to it
5. apply

Help and 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:

CHROMECAST - STREAMING PROBLEMS
* Thanks to @AtLmd Post
Lock screen MUST be enabled (simple screen lock swipe) I don't know why but it breaks the chromecast app's ability to resume smoothly if switched off
Synapse > Network > DTIM (both screen ON & OFF) = 1
Synapse > Network > WIFI Power Mode (screen OFF) = FAST
.
Thank you
Does it also work on N920I?
Any download link for testing?

Currently only SM-N920C - my device
Just in the final stages of cleanup >> update Posts #2 & 3 >> release soon.
Other variants :
users will require to post here the latest boot.img for their device and from which firmware build you extracted from.
download from sammobile.com or samsung-updates.com (1.5+ GB)
WARNING :
If your device is bootloader locked or similar restrictions, this kernel will not help and most likely end in BRICK
Warranty most likely voided as KNOX 1 flag is tripped.
Mine device is SM-N920C (Thailand) too. I've got it rooted from the thread of Manh_IT and it's randomly reboot 3/4 times a day. Will the issue solved when flash your kernel when it's available. Thanks for your time UpinTheAir!

I would not know about random reboot on your device. I would suggest to factory reset and immediately flashing stock ROM firmware to make sure your device is clean. After setup, flash SkyHigh kernel with Odin (FOLLOW INSTALLATION INSTRUCTIONS). Test first before making any modifications / tweaks and also before TWRP etc !!
I have no problems yet
v1.0 SM-N920C Initial release
v1.0 initial release for SM-N920-C device
Tested by UpInTheAir with :

stock N920CXXU1AOH4 firmware
no Xposed etc
no tweaks etc
no TWRP
XDA RULE #1 'SEARCH BEFORE POSTING". Please READ Posts #1-3 BEFORE flashing !!
Have fun

Ok, I flashed on my N920I for testing.
It works without any problems! No reboots during phonecalls at all! With all kernels I tried before, I had them, but not with this one!
Thanks for that great work!!!!
You can definitly use this for N920I also!

Please never quote the full OP ......
Anyway, thanks for posting your boot.img. Maybe you (or someone else wishes to "test" the kernel with your T model ? Just have full firmware ready if it boot loops or lose baseband etc.
If no good, I will then look at a separate kernel (time permitting)

Hey, no problem. Thanks again for the root scripts, although Andrei's method worked too, just saved a little time with Synapse UCI support.
Have still got loads more to do, but I'm running out of time before heading away for the next month ..........
I only have so much "free" time away from family and work
edit: ran out of "thanks" today, 8 is the limit, how stupid !!
Hey. I tested in note 5 tmobile and baseband is unknown thank you for your work tho!.

OK, thanks for the report. I will have to study the source and determine if modem drivers are different or just require some ramdisk adjustments or T-Mobile ramdisk.
Give me a bit and I'll see what I can do
Will you make this for SM-N920P please???!!!

Please check to see if the SM-N920C kernel boots for you and drivers - baseband etc are working. If not, please send me your boot.img. Instructions I gave a few posts ago. Just make sure you have the full firmware package toy flash if it goes wrong.
Amazing
I tested it on my SM-N920I too. No Problems so far. No reboots during calls any more. Anything seems to work. Couldn't find any bugs yet.
Thank you so much for your perfect work.
Your warranty is now void. Knox 0x1.
I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed.
Please do some research if you have any concerns about the features included in this kernel.

* Brief ideology of this kernel *
This kernel, if you plan on using it out-of-the-box it is battery life oriented, but also with a few tweaks to be fast and stable, just to give best daily usage results. The best part of it is that you can tweak it how you please depending on how far you want to go. You can choose over clocking CPU or/and GPU to get really good benchmark results, apply tweaks to get the best battery life/performance with low-end and high-end gaming or just to save even more battery, your choice. All this by using simple applications like Spectrum, a bit more complex ones, like Synapse or choose an even more advance way with shell scripts / terminal.
As the project evolves more features will be added, even as requests if properly motivated.
Before releasing an update, i'll make sure that it's properly tested so that you wont get bricked devices. This usually takes a lot of time, so please be patient. If some features are considered unstable they will be marked as experimental.

FAQ:
Q: How to flash kernel?
A: Download (download link in first post) and flash the zip file from TWRP Recovery. Wiping dalvik cache and cache when coming from other kernels is highly recommended.
Q: Phone is stuck with a black screen after I wiped dalvik cache and/or cache. After I waited a while it just rebooted. Is that a bug?
A: This is not a bug it's actually a feature. This is normal because the kernel startup script checks the dalvik cache to be created correctly. If it wasn't created correctly it checks again after 1 min, just to be sure, this is why you have a black screen. Don't force reboot, just wait! If Dalvik cache isn't still created correctly after 1 min, it will reboot and create Dalvik again, it will keep doing this until everything is ok. This can happen even 3 times upon boot. If more than 3 reboots happen then you have a ROM issue.
Q: How to configure the Kernel?
A: Easy way is with Spectrum app from Google Play Store. Synapse for more advanced users. Init.d scripts or Terminal/SManager or similar apps, for experts.
Q: I have issues with notifications, slow notifications while screen is off?
A: Disable battery app optimization for Google Play Services.
Q: YouTube videos are not playing, why? / Why am I getting random reboots (if using 99killer script)?
A: Remove the /system/etc/init.d/99killer script and reboot.
Q: Why not start with version 1.0 ?!
A: Because versions 1.0-1.3 were not released to the public and were tested in private by a group of dedicated people.
Q: What is NFS version?
A: Need for Speed version of the Phantom Kernel - higher and unsafe OC of CPU & GPU possibility. Only for Oreo versions.
Q:What is Smart Screen Dimming - SSD version?
A:It's a slightly modified version of this:
https://forum.xda-developers.com/s7-edge/development/amoled-pwm-s7-edge-t3517739
Q: I had a freeze/random reboot after I changed settings in Synapse, what can be the cause?
A: It can be a lot of things, but mostly an incompatibility in your chosen settings, if it's kernel related at all. The most known common things that are the cause of this can be Exynos-CPU-hotpluger (disable it), LMK parameters for Oreo version only (reset to defaults) or Doze settings (use stock). If any of these doesn't get rid of the reboots try resetting Synapse and wipe cache and dalvik cache. You can always post logs or details of your issue, to get help.
Q: After each boot i get my screen locked after a brief moment of using my phone and my phone vibrates 3 times, is this a bug?
A: This isn't a bug. The locking of the screen it's a workaround i added, to eliminate a bug where GPU utilization get's stuck. This will remain until i find a better way to solve this. There 3 vibrations is from the PK boot script telling you it has finished execution.
Q: Bixbi button remapper isn't working with Bixby button, how can I fix it?
A: Install Synapse and enable Android logging. (Thanks to @AiRMaX-360 for finding this fix).
Q: What is KernelSU - superuser module and how to get root access without Magisk?
A: Here you can find KernelSU project. This module can be used if root access is needed without Magisk. To get root access you need to create an empty file into /sdcard/Phantom-Kernel/ folder with the name "PK.su" and reboot. Remove the file and reboot to revoke root access.
PS:
* NOT all apps will work with it.
** This also has no app that control access so don't leave it always enabled!
*** If Magisk or other su is found, then that root access method will be used.
