BRIEF EXPLANATION ABOUT KERNEL FEATURES
UKSM
UKSM is about de-duplication of data in system memory rather than being another de-duplicating file-system. This improves RAM usage.
Dynamic Sync Control
The dynamic sync control interface uses Android kernel's unique early suspend / late resume interface. While screen is on, file sync is disabled. When screen is off, a file sync is called to flush all outstanding writes and restore file sync operation as normal.
Frandom
Frandom is a Linux kernel random number generator, which is 10-50 times faster than what you get from Linux' built-in /dev/urandom. 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.
CPU Boost driver
When certain bursty and important events take place, it might take a while for the current cpufreq governor to notice the new load and react to it. That would result in poor user experience. To alleviate this, the cpu-boost driver boosts the frequency of a CPU for a short duration to maintain good user experience while the governor catches up.
FAQ
On which ROM can I install nebula?
- nebula can be used on any AOSP kitkat 4.4+ based ROM. (Carbon, SlimKat, CM11)
What is the best and most stable configuration for nebula?
- Configuration depends from user to user. Still, the most stable configuration according to me and that I use is below. It might differ for you.
- Governor: SmartassV2
- Max. freq: 1.2 Ghz (OCing doesn't really have an increased and noticeable performance, rather it heats the processor and wastes battery for a marginal gain in performance as well as creates instability - random reboots etc. Google more about OC.) (Read the description on this commit.)
- I/O Scheduler - SIO
- Enable UKSM (from Performance Control app)
- Enable Dynamic FSync (from Performance Control app)
- I'll update this configuration as more tweaks are added to nebula
I get random reboots, what should I do?
- I am working on the kernel for myself and the kernel is quite stable for me. Still, if you face reboots see below:
- Make sure you followed the installation instruction written in Post #1.
- Make sure you "Fix permissions".
- OCing will always cause instability. Try reducing the max frequency to 1.2 Ghz
- It is quite possible that you don't know how to use a custom kernel. Not everything needs to be set at HIGHEST. Just because an "option" is there doesn't mean you have to select it. Try changing the configuration that meets your needs and satisfies you. If you set up the kernel properly, it would stop giving you random reboots.
- The only way to get things fixed is to provide logs. I cannot fix that I cannot see. Google, how to take logs to find and solve kernel issues. (kmsg/last_kmsg)
- Tell me a way in which I can reproduce the issue on my phone.
Does hotplugging work well with zzmove governor? I remember trying hotplug on s2vep and it freezed almost everytime while deep-sleeping.

Same issue on baffin too. That's why I have removed zzmoove from the kernel.
hmm... xenon92... already k2wl has made a custom kernel with O.C till 1.8GHz so why have you the max @ 1.6GHz ?

Read the description in this commit - Link
There has already been a discussion on CM11 thread about how much does it really benefit by OCing at higher frequencies. Refer to that thread's discussion for more info.
In short - OCing at too high frequency heats up the CPU (obviously) and doesn't necessarily increase performance.
Even though I have added OC till 1.6 Ghz, but even I don't use that setting. 1.2 Ghz is fine for me.
Another kernel for AOSP rom.....:laugh::laugh::good::good::good::good:
Installed the kernel in carbon ROM and is working fine....:good::good:
ll update more on the battery stat later...
any FC's anybody facing?....anything at all..during call or anything??..just asking..would have tested myself but my net is limited right now till tomorrow......so can't ..will surely tomorrow onwards download evry single one (as m xenon work fan lets say )...but wont risk using mbs if it got any bugs...

It's actually 1797 MHz, so let's say it's only 3MHz shy from 1.8 GHz
This kernel looks promising, I will download, install, and use it for a few days

Been in interactive with 1200 max for an hour now...
Dint tried overclock though...:fingers-crossed:
I need a lil battery life guys my service provider doesn't have 3g for now some TRAI issues and i stay away frm hme most of the time so using 2g and the screentime i get max is 3 hrs 30 mins wid evolution kernel processor=conservative,I/O=sio or sio plus and today i reverted back to cm's stock kernel and have flashed the latest build my biggest issue is when my battery drops down to 30% it starts draining drastically say like for 2 mins from 30 to 24% any help would be definitely appreciated have made calibrations until now again calibrating tonight and will test after that nebula for sure because only name i knew for best custom roms was and is XENON92!:thumbup:

If the system did a forced reboot to avoid further CPU instability, the options will revert back to default... correct me if I'm wrong.
pawitp also said in the CM11 thread, that the options dont instantly set on system boot. You may have to wait 1 minute and check back.

Thanks - my inattention. BTW - in my opinion this kernel has the best battery/performance ratio.
Now kernel is also AOSP compatible (2 versions available)
Looks rather interesting, Thank you

Thanks for sharing! It looks promising!
While we always appreciate members trying to share there are some issues with this thread and rom.
1. This rom contains a modified kernel so xda requires source code to be provided. I see no source code listed on the site that is linked in the Op of this thread and since the member is not the original developer I don't believe he has the abiltiy to provide it.
2. This rom appears to contain ViPER4Android Audio Effects the creator of this has very explicit instructions about including this in any rom which can be found here. I do not see that these instructions are being followed.

19-10-2017 * Updated to v6.0 * Changes are in red or can be seen at the bottom of this post in the changelog: I am always applying patches to hopefully improve the kernel,so check out the "Patches and tweaks applied" section for a better view of the changes as well.
Notes
ALWAYS read the "Known Issues" section before flashing. I will add issues I have noticed or have been told about. Some may be VERY important. If you fail to do this and experience an issue that is listed I can not help you!
SELinux is set to permissive in this kernel. You can change this to enforcing at boot if you wish via an app like Kernel Adiutor-Mod
About voltage control: Setting frequencies that are unstable are going to cause lockups,freezes and reboots. This is NOT a fault in the kernel. My suggestion is to move the voltages up or down slowly (+/- 25) until you find some stable voltages that you're happy with.
Enough people were having problems with the 1.6ghz overclocked version that I've decided to release a non overclocked (1.5ghz) build as well. I would recommend trying the 1.6ghz and only if you experience a bootloop or instability then use the 1.5ghz version. I will not keep older versions of the 1.5ghz build up. Only the latest.
Having troubles deciding on a CPU governor or an I/O scheduler? Here is an amazing guide. All credits to Saber. Be sure to hit the thanks button. He obviously put a lot of time into that.
Features
Based on the latest Samsung kernel sources
Built an updated Sqlite3 (from version 3.9.2 -> 3.19.3 that will be pushed along with the kernel install (you can verify this by running "sqlite3 --version" in a terminal emulator before the new kernel install and then again after)
Compiled with self-built (ct-ng) UBERTC 8.0
Patched Linux to latest 3.4.113
Used anykernel2
Unlocked CPU frequencies: 200MHZ and 300MHZ
GPU overclocked to 600MHZ
CPU Overclocked to 1.6GHZ
CPU voltage control ( Max voltage =1500mV. Min voltage =600mV)
DriveDroid support (add sysfs entry for cdrom to LUNs)
Implemented zen-tune v4.5
Added CPU boost driver
Added PIE net scheduler
Added support for USB keyboards (You need This app)
Reduced vm_swappiness from 60 to 20
Added I/O scheduler switcher by sultanxda (changes the I/O scheduler for a specified request queue to Noop when the screen turns off in order to improve power consumption while the screen is off)
Added Fsync on/off
Added dynamic fsync
Added Dynamic management of dirty page writebacks (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 - Not adjustable via Grarak's Kernel Adiutor app)
Proc: much faster /proc/vmstat
Full CIFS support ( Modules will be pushed with kernel install )
Introduced new flag WQ_POWER_EFFICIENT for power oriented workqueues ( Allows for power saving if selected in Kernel Adiutor ETC. )
Added /dev/frandom support ( It is yet to be implemented properly yet however )
Properly enabled faux123's powersuspend v2.5
Fading LED's
Enabled graphite
Enabled AIO
Readahead set to 512 (from 128 default)

Known Issues
Setting alucard hotplug along with certain other governors at boot via kernel adiutor etc can cause a reboot after setting is applied. So be certain to set the "delay" time in kernel adiutor or similar to 10 seconds or more,so if you have this you are able to cancel and change after a reboot.
There is a chance of some settings being reset after flashing the kernel (quick setting,sound,statusbar etc.) This is rather insignificant and all settings that have been changed can be set back in minutes.

Installation
I HIGHLY recommend that you do a full backup before flashing this kernel. I am not responsible if you lose any or all of your data.
1.Download "Spookcity_Kernel-N"
2.Place the zip onto your phones storage
3.Reboot into recovery (Volume-Up + Home + Power button)
4.Select install
5.Flash the downloaded kernel
6.Go back a few times in TWRP Select wipe -> Advanced wipe and wipe Dalvik/Art cache and the cache partition.
If you do not do this you are very likely to experience strange issues.You have been warned.Do not report problems if you did not do this.
7.Reboot

Yeah,I have temporarily removed synapse support. This is the reason its 2mb smaller. I will add it back once I have some things fixed. Too many things just don't work with it right now.

Not positive what you mean. If you mean the size it will be the same as this as I haven't messed with synapse any yet. If you're talking about the features I've added since this build,you can have a look Here to get some idea of what I've done so far.

Hehe,yes. This build is based on the "OC CPU to 1.6" commit. So it includes everything before that,but nothing after. I will probably be releasing test builds in increments. Meaning,the next test build (hopefully this weekend) will still not include all that you see committed on my github repo. I want to do it this way to better be able to diagnose possible bugs and their reasons. So I'll release a test build on github. Have you and others willing to test give me feedback about any problems. Then release it on here...and then repeat these steps. Hope that makes some sense [emoji3]

I'll make sure the next test build includes much of the new stuff. I'm a little bit worried that the GPU overclock is going to turn into a nightmare like the CPU overclock though. Guess we will find out. Fingers crossed.
Sent from my SM-G800F using Tapatalk
I would very much like to see voltage regulation. Is there such a function?
I can test the overclocking of the GPU as well as the CPU 1700)))

Haha,You're definitely not testing any CPU overclocking [emoji3]
I have started messing with voltage control. I've enabled access,but at this point I'm unsure how you would access it as its not included in kernel adiutor and I've yet to properly set up synapse. Either way,the access is there,but the ability to actually change the voltages is not currently working. I believe I need to tweak a few things and add at least 1 additional file. Soon to come I hope.

Honestly I'm unsure off hand. However,I did enable arch power by default,so that should help battery life some. I have been working on the kernel recently and have added alucard and alucard hotplug CPU governors. This will come in the near future and I believe could really help with battery life.
I have some problems with kernel. After update my RR 5.8.3 i try to instal your kernel, but TWRP showed me that error message "Unsupported device. Aborting...
Updater process ended with ERROR: 1". I have a G800F and i don't know why kernel can't install. I attached my recovery.log file

upd. : it was a new twrp. I installed old version twrp and try to install kernel. And kernel was installed

Yes,this has something to do with the latest TWRP I believe as I now get this error as well. I'm not sure why. I'll look into it. To "fix" it for now. Open up the zip (don't unzip it) then open the anykernel.sh file with a text editor and change the line "do.devicecheck=1" to "do.devicecheck=0" Then it skips the device check and will be fine.

I wiped dalvik/art cache and cache partition via TWRP 3.1.1.0. Anyone else has/had this? Suggestions?

Model is F.
Rom is 14.1 Lineage, the 20170226 version from Ayke, i think.
"A kernel is the central part of an operating system. It manages the operations of the computer and the hardware - most notably memory and CPU."
It should be installed via Recovery (TWRP) over any LOS/AOSP 14/15/16/17-Based ROM. It doesn't need any tweaking with any app, just install it and use it.
BUT you can use Boeffla Config app (available here on the next post) or Kernel Adiutor if you like tweaking.
This kernel uses codes from other kernels, as you'd expect in an open-source community, most notably code from Boeffla, SmartPack, Lolz, Ares and Intelli-kernel
It has UNIQUE features like:
- a different "low memory killer" algorithm wrote by me. Extremely simple, but multiple apps can be killed in a batch!
- zcache is disabled for really *freeing* up memory that was used for caching files
- a different default cpu hotplugger. ALL kernels (even LOS/stock) relies on Qualcomm's vanilla MPDecision, I wrote my own
- Tuned CPU governor (it's the default). It's basically the Interactive governor but with a LOT of tuning to match up with the tuned hotplugger. Did you know stock/los roms uses a multi-socket Interactive governor that doesn't match our phone's cpu?
- many many many MANY compiler optimizations not found on boeffla kernel, LOS or anywhere else!
- MANY unused code simply REMOVED to free memory and CPU. People ADD a lot of stuff on a kernel, I like to remove
- compiled with 2019 GCC version 9.1 (instead of the ancient version 4.9 that EVERY ROM uses)
- Your battery will be charged to "real" 100% like TWRP does
- many unstable cpu and gpu governors and i/o schedulers removed. they only wasted space
- ext4 tweaks
- fair scheduler tweaks
- removed 3 touch boosters code.. why so many? just to raise your clock on every single touch?
- Maple i/o scheduler
- lowered "read ahead" of files and inodes.. why would you read something you don't know you'll need?
- lowered maximum i/o requests for lowering ram usage while writing to SD (internal or external)
- removed a lot of DEBUG code.. why release a software with debugging code built-in?
- removed network protocols we would never use
- removed some compatibility code
- removed dynamic fsync, why would anyone want to enable fsync in any moment anyway? it has been disabled by default linux kernel for decades!!
- decreased commit DELAY of file changes from 20s to 5s, which is linux default. there's no advantage in keeping new/modified data on ram for too long
And common features:
- Max cpu voltage set to 1.4v
- Min cpu clock set to 268mhz instead of 300
- Max cpu clock set to 2995mhz instead of 2457
- Max gpu clock set to 657mhz
- Compiled to speed, not size
- Voltage table for undervolting or overvolting
- Charging level for AC, USB and Wireless charger can be set
- LED fading control + brightness
- zen, noop bfq and sioplus i/o governors
Overall your phone will be snappier, and less battery hungry
You can go back to your rom's default kernel by simply installing rom's .zip again. No need to wipe anything ever!
