Welcome again! This is a Re-work of the Artx Kernel now working on Oreo! G3X Ultimate Kernel will be released replaced with ArtxUltra AnyKernel Installer. Like I said this is a Re-Work of the Original Kernel so, it's compiled with a more optimized Toolchain (GCC) and works better than before, just give it a try and you'll know of what I'm talking about...

Features Guide:
CPU:
- Governors: Read this
- CPU Booost: Boost your CPU Frequency on screen touch event, my kernel has per-core touch boost frequency so you can configure how many CPU's will be boosted at your preferred frequency.
- Hotplug Boost: When a Core is plugged, it gets boosted a little
Thermal:
- Core control: Enable and disable throttling, this enables the thermal engine and enable VDD restriction and core throttle. Be careful with this because an excesive overheat can reduce the device life time (and battery)
- VDD Restriction: Limits CPU voltage, limiting it will decrease temperature
- Core Throttle: Throttles CPU when enabled, this decrease CPU frequency to a lower step when it reaches a specified temperature
GPU:
- Gaming mode: The GPU will be always at maximun avalible frequency (Not always at 578Mhz because thermal engine can throttle the frequency)
- Simple GPU Algorithm: Like the name say, is a simple GPU Governor that works like simple_ondemand, I recommend more Adreno Idler
- Adreno Idler: Please read this
Don't enable Simple GPU and Adreno Idler together, this can result in a bad GPU Managament and it can generates overheat, also, those two algorithms only works on the "msm-adreno-tz" GPU governor
Screen:
- You should know how to config it at your liking
Sound:
- My kernel uses Faux123 sound control, you can set independent headphone gain that's a kernel level sound gain, so, this will not distortion your audio until you put a very high value.
Battery:
- Fastcharge: Forces Fast charging (This can reduce your battery life)
- Arch Power: Enable or disable some Arch especific power funcions for battery saving
- PowerSuspend Mode: I didn't found information about this but I know that the best option is "Hybrid"
- State Notifier: This driver notifies screen events (when you touch it). It works with Maple scheduler (You need to enable this if you're going to use Maple) and other kernel things.
- Krait C-States: Power saving settings, I recommend to disable only "C1 (Retention)" because if can cause screen flickering and slow the phone wakeup.
I/O Scheduler:
- Scheduler: Read this
- Read-ahead: The Re-ahead value on the phone memory, because the device memory is very fast, it should be at 128kB, for SDCards that are a lot more slow a good value is 1024kB or 2048kB
- Rotational storage: Treat device as rotational storage, like HDD Hard drivers, just leave it disabled, we don't need it
- Add Random: In some cases, the overhead of I/O events contributing to the entropy pool for /dev/random is measurable. In such cases, it may be desirable to set this value to 0
- I/O Stats: Like the name says, it maintains I/O statistics, if you disable it, memory monitoring apps will not work. (I don't need this so I disabled it)
- RQ Affinity: Try to have scheduler request complete on the CPU core they were made from. This can be a power saving feature
Kernel Samepage Merging:
Don't touch this if you don't know what you're doing
Low Memory Killer:
- Adaptive Low Memory Killer: Keep this feature enabled because it'll save you from random freezes (It makes Low Memory Killer aggresive dynamically when a thrashing scenario is detected)
- Low Memory Killer profile: "Agressive" is recommended, if you think that it'll close all your apps you're wrong, we've 3GB of RAM and these are the settings:
* Foreground Applications: 4MB
* Visible Applications: 8MB
* Secondary Server: 16MB
* Hidden Applications: 32MB
* Content Providers: 48MB
* Empty Applications: 64MB
Virtual Memory:
Every detail about this settings are well explained in Kernel Adiutor, but in general there's no need to touch this
Misc:
- Android logging: Disabling this can improve your phone a bit (It's not noticeable)
- Software CRC Control: Is a driver that prevents data corruptions but data blocks can lose up to 30% of perfomance, you can safely turn it off
- FSync: The kernel provides system calls for syncing single files and filesystems which flush the corresponding file buffers to storage. Disabling FSync reduces the number of I/O Opetaions which can improve the responsiveness of the device and reduce battery drain. However, disabling it increases the risk of data loss on a crash/freeze.
If your ROM with my kernel is very stable, you can safely turn off FSync and if you're on f2fs filesystem NEVER turn it off because you gonna have to format EVERYTHING if the data gets corrupt by a crash/freeze
You can always recover your phone in case of data corrupt if you're on ext4 filesystem with TWRP, in wiping section -> select which partitions to wipe -> select one and press on partition settings or more settings.
This is all for now! I'll explain each new feature that I introduce in my kernel here, thanks for reading and I happy twaking!
Spectrum Guide:
Spectrum Kernel Manager!! Thanks to @frap129!!
This amazing app let you select between 4 profiles, Battery, Balanced, Perfomance and Gaming,
all of these configured by me:
Battery: I've set various battery savings configs here, it's designed for the best battery savings and if you don't care about UI lags then this is for you
Balanced: As its name says, a very good balanced profile that evit UI Lags and the battery keeps still awesome, you can use this profile to run games without getting your phone overheating
Perfomance: This is not a pure Perfomance profile like others that simply puts your governor in "Perfomance" and things like that, this profile keeps all the UI Smoothness anytime and it doesn't drains the battery, if you're very UI Lag sensitive then this is your profile. Recommended
Gaming: Pure perfomance, play any game with this profile at maximum power, this profile keeps the FPS constants with blu_active governor, if you don't care about battery life or overheating and just want to play games then this is for you
Also, All this profiles are customizable, look at your internal storage ~/Spectrum/profiles/ folder, there's 4 files for each profile. If you don't wanna mess with all the kernel features then I highly recommend to you Spectrum!

Finally guys! We're updating our G3's!
All of my progress from the begginning to now and the future ones, has been made with my Virtual Machine in the cloud, but I'm running out of credit and I can't develop on my computer.
I'll apreciate a lot if someone can donate to me to keep this project for all our G3's alive, thanks you

Thanks for updating the kernel so I could include it in my LineageOS builds!

flashed over 10.23 oreo's build from HardStyl3r on d855, and yes you need to flash mr.bump (got a black screen after aroma setup)
edit: damn, its faaassstt!!!
Thanks!

First: Thank you for this fast Kernel.
But I encountered a Problem with the external SD card. After installing this new ArtX Kernel, a Notification about a defect SD appeared, it was rendered unusable, unless formatted. That's not true as other Kernels (stock AEX, stock crDroid, stock RRmx) have no Problem with it.
As I don't want to backup all my data (about 90 gigs, as it is a 128gb card), format and recover it, it's a deal-breaker for me.
My suspicion is that the exFAT filesystem isn't implemented, as an old 64gb card formatted as vfat was accepted without problems.
Is there a solution on the horizon?
PS I don't remember the "old" ArtX Kernel having a Problem with this card, but the G3X having one, if that's any help at all.
Thanks in advance.
Addendum: As reverting back to stock AEX Kernel solved the problem, it is definitely Kernel related.

I'll look into that and fix it for the next build

Thank you for the prompt answer/promise?! Looking forward to using (i.e. enjoying?) ArtX again!

Tried flashing D850 with straight lineage OS, got a blinking red/blue light.
ROM, Kernel, Magisk 14.

Hi, I had a question. I wanted to know if the sensors were not working because of the ROM or the kernel? I'm confused a little !!!!! you can guide. I am aware of you for continuous activity in this field.

D855
First impression:
Lineage 15.0 and kernel. Battery full charged at 00:00 yesterday. Right now (have passed 16 hours, with alarm clock, qcview in the background, 2 calls and 2 whatsapps sent) battery show 98%.
For me, good speed and good battery

It may temporarily return to marshmallow stock, but right now, 78% after 24 hours, after an oreo gapps flash and after installing and testing several apps. Artx + lineage 15 kernel team promises

Anyone looking or need Mr. Bump
I attached it on this post.

Thank you very much mate for your effort! May I ask what will be the difference between artx and G3x?
