[POLL] Top Kernel

Best kernel for battery performance and user experience (Lag free).
Please mention:
- Which ROM you are on and the kernel version
- CPU Governor if not default
- I/O Scheduler if not default
- If you manually UC/OC the CPU/GPU (mention frequency)
- If you manually adjust UV values then how low (if not kernel default)
PS: If any other Kernel apart from the Poll options then do write about it.

Let me start off
- Stock (rooted) with Franco R15
- Governor Interactive (default)
- I/O Deadline (default)
- No OC/UC done to CPU/GPU (default)
- No UV done (default)

Firstly, should NOT be in this section, maybe in General. Secondly, I'm pretty sure best ROM/kernel threads are not allowed on xda, or so I've been told.

This is not appropriate for a development section. Moved to General.

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.

Flash agni, flash stock boot.img from ROM, flash other kernel to get fp working. Also, you can make a zip with only libs like I did.

[KERNEL] [G800F/M/Y] Spookcity_Kernel-N (For all 7.x custom ROMS)

Code:
/*
* Your warranty is now void.
*
* 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 features included in this kernel
* before flashing it! YOU are choosing to make these modifications, DO NOT
* point the finger at me for messing up your device.
* this kernel is only for the S5 mini SM-G8OOF/M/Y (Exynos) Do Not Flash this on any other device!
*/
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)
Reverted "Enabled arch power" (There will be a switch to enable/disable this in the next build)
Many build flags for optimization
Added optimization flags for the GPU
Many more features being worked on and coming soon

- tripndroid
- bfq-v7r8
Added many TCP congestions
- reno
- vegas
- westwood and more
- Added the rest of the TCP congestions
- Westwood is now default TCP
Patches and tweaks applied include:
- Updated ARM topology and added cpu_power driver
- Input: Improve the events-per-packet estimate
- block/partitions: optimize memory allocation in check_partition()
- block: bfq-iosched: tuning for SSD (thanks to anarkia1976)
- cpufreq: Move get_cpu_idle_time() to cpufreq.c (This is important for CPU governors to work better/more efficiently with our kernel version-3.4)
- Fixed all the CPU governors to work properly with the Move get_cpu_idle_time
- cpufreq: Introduce new relation for freq selection (It selects the frequency with the minimum euclidean distance to target. In case of equal distance between 2 frequencies, it will select the greater frequency)
- cpufreq: conservative: Set MIN_LATENCY_MULTIPLIER to 20

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

At 2Mb less than the test version. Has something removed or new compression?
On RR works.

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.

Now I do not understand anything)). Alucard has already been added, GPU OC to 600mhz, fifo, tripndroid and vr IO sched .....? Or will be added to the test version.

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]

It is certainly correct and logical, so it will be easier to search for the culprit of mistakes.
But I want to try everything at once))

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.

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.

Good stuff, changing SElinux to enforcing make sim card not detectable is there a recommended config for better battery?

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.

Just flashed the kernel and the mobile got stuck in a boot loop. Tried it second time: First very long boot, then crash.
I wiped dalvik/art cache and cache partition via TWRP 3.1.1.0. Anyone else has/had this? Suggestions?

I have not had this problem and haven't had anyone mention it to me. What model is your phone? F,M or Y? What ROM?

Model is F.
Rom is 14.1 Lineage, the 20170226 version from Ayke, i think.
