Changelog
R11 (aka Synapse release)
NOTICE:
Due to heave Synapse changes again, I recommend to clear Synapse data, before you flash
If you feel unsnappy, raise Touchboost values, completely set both down to 300MHz at init
Synapse settings added & reworked (spent whole day into Synapse primarily)
Synapse can now make a flashable zip from your backup profile to share with others (look under tab Synapse)
Removed some sound pre-settings and removed FauxSound control for now to prevent still unknown issues
a few more fixes
R10 (beta)
NOTICE:
I recommend to clear Synapse data!!!
Synapse should now have enough options for daily settings
So please dont mix apps for setting kernel features
Synapse settings added (very hard work.....half day wasted here...)
S-Browser crash fixed on S5 ports
Sound issues fixed and quality should be improved
completely switched to UKSM now
a few more fixes and patches from different sources again
PS:
Please dont complain about voltage control in Synapse
If you want to experiment with voltages, you can set them one by one yourself
R9 (beta)
NOTICE: this will break some of Faux Control App functions, especially frequency setting, until Faux updates
If you dont want to run a beta, stick with R8 until stable release
There is currently not voltage, thermal, screen, zswap control in Synapse!
update to Linux 3.4.92
Synapse is back (but not everything is implemented), check yourself, big thanks to UpInTheAir, which made a very detailed Synapse layout, which I used as base
Hardlimit Interface update to 2.0a, you can now set screen on and screen off max/min frequencies separately, wakeup kicks, touchboosts, DVFS lock... check Synapse
GPU OC with Snapdragon 801 values (up to 587MHz)
Ramdisk is now LZ4 compressed (need to check kernel for LZ4, too)
Led Control updated to V1.2
IntelliPlug updated to newest version
Logger can be enabled/disabled through sysfs interface
many fixes and patches from different sources again
R8
finally working NE6 base with all known features
R7
updates base to NE6
same as R6
R6
switched to faux123-yank555 kernel as new base
over 300 commits added, patches, fixes, enhancements, etc...
see features
r5
lower power frequency 268,8MHz should work now as expected
lowered voltage for 268,8MHz (its really low, report if unstable)

Not yet, because I remember problems with frequencies are not used and also decrease performance with gpu set to 550

About GPU overclock:
My phone is Samsung SHV-E330S, which is basically GT-N9005 in S4 case, so 99% hardware is the same.
According to my investigation in GPU overclocking, frequencies are handled fully inside RPM firmware. Frequencies in .dtsi files aren't used. RPM uses its own frequency table and cannot be changed from linux side. So, your GPU OC simply doesn't affect actual GPU frequencies. Linux GPU governor will think it uses new frequencies and will actually switch to a wrong frequency (because RPM will use hardcoded unmatched freq table) - so everything will go wrong (as you already noticed, probably).
I've monitored GPU/PLL hardware registers and saw, they work according RPM's table and not affected by .dtsi settings.
There is the only way to overclock SD800 GPU is by modifying PLL settings (as it was done for SD600 GPU). There is PLL for highest GPU powerlevel's frequency which used solely by GPU (just like in SD600). But performance increase is not so high as it could be from increasing RAM frequency OC (which i didn't manage to tweak yet).
P.S.: I don't know about N9005, but in E330S standard highest frequency is 550MHz (according to PLL settings) instead of 450MHz as advertized in MSM8974 (not AB or AC), although in .dtsi files max frequency is 450MHz. Good bonus from Samsung
Probably, in N9005 it's the same.

Thankyou for your patience. It was quite helpful to learn a new thing.

I have got a problem when put on usb charge it stays on high frequency and instead of charging, the phone battery gets dischaged slowly. anything i have to do.

Works on Official CM12.1! Thank u DC

No update?

just tried this kernel and seems great (much snappier than stock cm)... only issue is cam does not work

Great work OP, but same here, camera FC all the time, even with different cameras =(

Hey, very nice kernel with lots of options and features! However, like the others above, the camera says it is busy and closes (motorola app, but should be the same with other camera apps). The torch (flashlight/flash) also does not work, probably same problem as with the camera. Could it be because of your modification of torch power by 20ma?
Tested on cm12.1
Cheers

Camera doesn't work. Torch is completely removed. Are you actually going to update this?

Locking this one, until I make a fully working zip.
Links will remain and users who want to give a try can go ahead.

Installation Instructions​
If you're updating from previous versions of Ethereal kernel or flashing a custom kernel for the first time
❯ Flash kernel ZIP -> Reboot
If you've flashed a different custom kernel before but would like to migrate to Ethereal
❯ Flash boot.img of your ROM (located in root of ROM ZIP) -> Flash kernel ZIP -> Magisk (optional) -> Reboot
The kernel ships with stock vibration patterns by default. If you'd like to switch to the modified one, simply add the keyword modvib to the file name before flashing (e.g. EtherealXO-30.0~Deity-GCC930-Mido-20200825-modvib.zip). Once this is done the ZIP MUST be flashed from recovery instead of through other means such as FKM's flasher.

Normal USB charging current is 500mA. This is increased to 900mA.
This is not related to Quick Charge.

No, I mean when I am plugging my charger I can't see current above 900mA but in other roms it goes upto 1750mA.

NOTES:
*This kernel has been designed with stability and performance enough to get you a
good battery life.It has been specifically designed for normal app usage and multitasking.
System-As-Root support:This has been provided so that the kernel is compatible with Android 10 roms that
require System-As-Root to function properly.Use the NO_SAR version if you are on a Pie rom, or use the SAR version
if you are on a Q rom.
*Thermal issues have been somewhat mitigated.Note that the values present in thermal-engine.conf and the dtsi
files are marked EXPERIMENTAL.According to tests performed,temperature on daily usage has been reduced.
But due to reduced values,GAMING will partially suffer due to little/random FPS drops.
In my testing,playing games like Crazy Taxi,various indie games,Rebuplique,GTA SA etc. was smooth,but a *gradual* (not sudden)
rise in heat was noticed.Others complained that games like PUBG had FPS drops and bit of a performance decrease.
WARNING:This also modifies your thermal-engine.conf file.
*Undervolting is an experimental feature.In case you do want to modify voltage values,open Smartpack/Kernel Aduitor Kernel Manager,go to the CPU Voltage Tab,and modify only the values labelled as "perfcl_Vmin".Reducing the values by 5 is recommended.
If during undervolting,the device freezes,simply long-press the POWER button until the device reboots.
*This kernel is not for heavy gaming.Please be aware while playing games/using heavy apps.
*RAM usage,battery life,performance etc. can vary with usage.Please dont complain about any problem if you apps
are wildly running in the background or you dont maintain your device properly.Sometimes it is not the fault of the kernel.
.Please provide proper bugreports(/proc/last_kmsg,dmesg output,/sys/fs/pstore/console-ramoops files can be provided)
otherwise your bugfix request will be ignored.
*Profiles are provided above.If you do have the time,do tell me how these profiles work out for you.
*This kernel gives me a maximum of a one-and-a-half days on a single charge.I use lots of apps and multitasking is smooth.Obviously,don't take these claims for real,test test test and apply settings that are perfect for you.
Everything depends on how you use it.

Bro Link updated in first post,go ahead download and flash the kernel.

Guys I would really appreciate it if you all gave your honest reviews about the kernel.I want to further improve the kernel,and it doesn't help when you people dont tell anything and keep the thread silent.
