Hello, friend.
Inspired by @wrongway213's original custom kernel for Pixel 4/XL, I decided to make my own project starting with the PIxel 4a 4G, and then wanted to expand the support to the Pixel 5a 5G. The naming is a tribute to both his ideas and Mr. Robot. fsociety tribute's goal is to give the device a set of useful features while ensuring its stability for a daily life usage. Those features and changes are pulled from different places like Sultan kernel, Arter97 kernel, Kirisakura and many more.
Features
General features
Built with Google Clang version 14.0.2 + LLD linker
Full -O3 build with chipset's flags included (thanks to @eng.stk and @Sultanxda)
AnyKernel3 powered installation to stay OTA and flashers (EXKM, FKM...) friendly
ARM64 architecture optimization and performance patches
Merged security and code fixes from Qualcomm - CAF
Filesystem (ext4/f2fs) optimizations
Scheduler code improvements for better CPU tasks assigning
Disabled several debugging cruft
Network related features
Set BBR as the default TCP network congestion control and switch to fq_codel queue discipline
(this combination improves network speed and reliability - thanks to @kdrag0n)
Enable support for TTL spoofing
Update Wireguard to its latest release
Power-saving related features
Display "power-saving tweaks" merged-in (from Proton kernel)
Reduce the GPU idle timeout set to 64 ms and implement GPU power-saving changes from Sultan kernel
battery: Tweak QG SOC to be more linear/monotonic (from Proton kernel)
That fixes the stock kernel's unlinear battery level curve, especially between 100% and 90%. The device will need a few charge-discharge cycles to take it into consideration
Performance related features
Faster system call filtering using BPF JIT (from Proton kernel)
Implement LRNG and enable it as default for better performance (more info at: https://www.phoronix.com/scan.php?page=news_item&px=LRNG-Random-2021-v41)
fuse: give wakeup hints to scheduler to speed up compress/decompress in internal storage (from Qualcomm,
found in P6's Kirisakura kernel)
Disable the GPU memory usage tracing (which was enabled for debugging purposes)
Other under the hood changes
Extra features
KCAL Color Control support (from ElementalX/Cleanslate - thanks to @savoca, @tbalden, and @flar2)
Vibration Control support (from ElementalX)

Yes. You will then be able to flash the kernel using a kernel flasher like FKM or EXKM!
Flashed and running good. Thanks for your support.

I have flashed your kernel as well and I'm very pleased how smooth and stable my phone is now. Is it possible to implement smart charging feature?
Am I still able to use Pixel-specific features like call screening with this kernel?

I don't believe flashing the custom kernel shall have any consequence on that, so yes! Don't forget to use the SafetyNet fix from kdrag0n to spoof your root status, just in case.
The next build is currently being tested on the Telegram group. It shall be released on XDA very soon!

I believe they mean the phone limiting the charging rate overnight based on usage patterns and the set alarm, so that it only reaches 100% just before the alarm goes off.

I appreciate your answer. The kernel follows stock's initial set of features, so that should be usable with fsociety tribute as well.

Smart charging was one of the feature in A11 custom kernel to set limit cut off charging(e.g. 80%) to extend battery life cycles.

Hi,
Love your kernel changes. Much smoother and my pixel 5a doesn't overheat as much.
However, when I flashed 1.43, my wifi stopped working completely. Like it won't let me toggle wifi on and off.
I reverted to my patched stock kernel and wifi worked again. Same goes for 1.0 release of f-society.
Does anyone else have this issue?

Does this kernel add support for usb wifi adapter?
Hello everyone!
I hope you're all doing well. First of all, thank you for your support as always. I would also like to apologize for the sudden communication silence which wasn't planned. Sometimes life gets in the way, and you've got to make choices.
I fortunately found a part-time job and the first weeks were mentally and physically draining. If everything goes well, I will be able to buy a Pixel 5a soon in June, so that I may work again on the redbull/barbet kernel builds while also keeping my 4a 4G as my second device to maintain the original fsociety tribute project!
Excited to come back and exchange with the lots of you, but also address the reported issues.

16.4.0: Rebuilt from scratch under fresh new source.
16.3.0: This kernel is being released as is, I made many many changes, I would take heed
when installing this kernel, keep an eye on it. Some things I am not very happy about.
(Then why release? Because I need to make sure its not just me.)
16.1.9: Re-based Kernel, made some cosmetic changes, also reworked defconfig,
Gesture Controls for AOSP based ROMs, will not work, But OOS it will.
WiFi has been tested to work on .10 but many have complained that it will
only work when they upgrade to .11 (Keep this in mind when you report problem)
16.5.0: Both Stock and Custom AOSP Gestures work, (depending on your ROM)
16.1.0: New Download Location added: Also, this is probably my best release yet.
qcacld-3.0 is now compiled inline with Kernel.
Attention
This is strictly created for OOS, but it has been tested on Custom AOSP based ROMs,
on AOSP, everything works, But WiFi and Gestures, (WiFi uses stock WLAN module) (Gestures, need the API, I never added yet)
One day I will add that in the near future if people on AOSP based ROMs request so.

Nice to have another kernel with good set of options. Is this for OOS/HOS or custom ROMs? You might want to specify it in OP
@Eliminater74
Glad to see you here. I'm excited what you make possible on the OnePlus 6.
Best Regard's
Alex1911
Is this kernel for custom ROMs or only oos?
Will testing now.
Welcome aboard! I fallowed you from htc 10 days , great work !!

Lets give it a try right now ! an see how the beast behaves
Why when I want boot into TWRP it freeze at twrp logo?
I been working on making This Kernel OMNI, meaning to work on both AOSP and OOS..... Had it tested on AOSP under 2 dif custom roms, and only thing that was wrong was WIFI not working, and Gestures not working,
reason WIFI not working, because I used STOCK module, as for gestures, because I am using STOCK gestures implantation.. I need to add the custom AOSP Kernel API for gestures then gestures will also work on custom roms..........
As for WIFI, I maged to get qcacld-3.0 to build and compile with kernel, Booted up, and seems to be working, because the stock module shows empty when I check with 'lsmod'...
but I do have wifi, so the built into kernel qcacld-3.0 wifi seems to work fully........ But I need to keep my eye on it and test it out.......... see what lays ahead............. If all checks out.
ill be releasing next build with built in wifi.. and get other peepz opinions..
Pressing the fingerprint is mapped as a home buttons....
How can I disable this ?
Also thanks for this amazing kernel.
Damn, your kernel was dope on LG G3 coupled with XenonHD ... Gonna give it a try !
Update: Nebula Kernel 16.1.0
Get it in Downloads........
Thank you. It would be great to be able to use this kernel with AOSP as well. If a single image is not achievable, other developers approach was to include an image for OOS/HOS and another for custom ROMs in the same zip, to overcome the incompatibility issue. Anykernel2 can detect the OS and flash the right image.
Read up a few posts. He's working on it.
Will try.

Yeah im not into detecting OS and having 2 DTB's in ZIP.. I think thats just pointless, I know this kernel at its earlier stages was tested on AOSP based rom, and only thing that didnt work was wifi and gestures.
I have solved the WIFI issue but building qcald-3.0 inline with kernel, and it seems to work.. many changes done to the qcald for it to work like that.. anyhow.........
next is gestures which is pretty easy to fix. but I dont wanna lose STOCK gestures support, so im trying to figure out a way to keep them both together.

because it is made especially for Exynos7880 devices. Other apps like kernel adiutor or Mtweaks
do work too, but they may miss some settings.[/CODE]
DISCLAIMER
Code:
*Im NOT responsible for bricked devices, dead SD cards or any damage done to your device.
Compatibility
This kernel is compatible to all variations of A5 2017 and A7 2017.
Only A520F is well tested as I have this device.
Features
Latest A720SKSU5CTL2 kernel release
Linux 3.18.140
Support for AOSP 12, AOSP 11.0, AOSP 10.0, Treble 11.0, Treble 10.0 and Rise-Q
CRC control
Frandom
UKSM (Ultra kernel samepage merging)
ARCH power
USB charging default changed to 900mA
CPU and GPU voltage control
DevFreq voltage control
CPU overclock to 2002 Mhz
GPU overclock to 1034 Mhz
Configurable wakelocks

Just flashed it. Already encountered a bug, hk keeps on loading. Looking forward on your developments. Good luck
And unlocking the phone through fingerprint seems slower now for some reason. Opening apps is also slower now. Btw im using Google pixel Pie Plus
Flashed it and working good so far. I think you're the first to make a custom AOSP kernel for this phone.
Magisk 20 is working for me, it just takes a few tries to boot sometimes.

Unlocking the phone takes longer because the CPU clocks down on all cores when the screen is off. Therefore it needs longer to unlock. At least this is the explanation that makes the most sense.
That apps are opening slowly sometimes is also a bug I encountered, forgot to mention it in my OP thread. This can be fixed by simply reinstalling/updating the app or doing a clean flash (install ROM, then kernel right after)

Hotplug in general
I'm laughing so hard thinking of this title as "Riiiiise and Shiiiine" Project
Good work btw
With crDroid and this kernel, I got 106k in antutu. I love the fast charging too. Such an upgrade compared to "stock" aosp.
Latecomer... flashed and rebooted first time on Magisk 20 using crDroid
Going to have a play with some features and report back if I find anything useful.
Thanks Simon

So far so good. Been trying some settings I had on my Xperia SP about 4 years ago and they seem to be working well for a balance of performance and battery.
Simply put:
CPU governor - Interactive (max and min frequencies set at maximum and minimum accordingly)
I/O scheduler - Fiops with Internal Storage read ahead set to 1024KB
I/O scheduler - bfq with External storage read ahead set to 1024KB
No CPU hotplug (really only useful for stock Sammy kernel)
That's it
Feel free to try and report back with your own findings.
I'm finding little lag now (was getting some really big lags and micro freezes) and battery draining slower

My results was with GPU overvoltaged and no apps other than hKtweaks, magisk and antutu. So hardly real world.

Thank you for this great kernel. Stable, good performance. no hanging or error. everything works as it should with LineageOS 16. Only the battery is empty 1 to 1.5 hours faster. Is maybe the tribute for the good performance.

Hi all,
this is the thread for a custom kernel i made for Samsung Galaxy A30.
The custom kernel has been named Eureka which is a greek work which means "I have found the solution". This multi-purpose kernel is the solution for battery, gaming, performance for A30. On creating this kernel, I believed that 1 kernel can be all of the above if properly tweaked!
As from Eureka R9.0, four kernel variants are available inside 1 same zip. This has been made possible using AROMA Installer.
Compatibility:
This kernel is compatible with AOSP GSIs/ROMs, OneUI2 and OneUI3. As from R9.0, there is only 2 variants of zip to download. One is called EMS and the other one is called HMP. Continue reading to learn more about them.
FEATURES:
* Disabled Samsung security features
* Enabled all governors + added other governors
* Overclocked CPU as follows:
BIG Cores: from 1768 MHz to 2288 MHz.LIL Cores: from 1586 MHz to 1794 MHz.* Underclocked CPU as follows:
BIG Cores: from 936 MHz to 208 MHz.LIL Cores: from 839 MHz to 208 MHz.* Added GPU thermal and voltage control
* Added latest boeffla wl blocker V 1.1.0 and disabled some wakelocks
* Network speed improvement
* Enable zram support and set default compressor as zstd.
* Switch to a lower charging voltage more quickly.
* GPU max frequency overclocked from 845 MHz to 1300 MHz
* Implemented Dynamic FSync 2.0
* Implemented a custom hotplug driver to enhance battery management
* Implemented Power Suspend driver
* High torch brightness on custom roms/gsis
* Has Spectrum support
* Automatic detection of magisk - If u are rooted, u don't need to flash magisk after kernel.
* Upstreamed kernel version from 4.4.177 to 4.4.302
* Built with Vortex Clang 14 toolchain with LTO. Reason: Better performance
* Support for EMS (Exynos Mobile Scheduler) added
Please read the changelog on github for full list of changes.
KNOWN ISSUES:
* Maybe ADB cannot be used at the same time as MTP
SOME MINOR TWEAKS FOR BEST GPU PERFORMANCE:
* Set GPU power policy to "always on"
* Set min and max GPU frequency to 1200/1300 MHz
* Disable GPU thermal manager to prevent GPU frequency from dropping
* Games don't require high CPU frequency because they depend more on GPU. You can therefore decrease CPU max frequencies to reduce heating of the device.
We have developed our own kernel manager called EKManager which is a fork of HkTweaks. It is compatible only with Eureka Kernels. You can download it from here:

Reference about EMS kernel:
Energy Aware Scheduling (EAS) gives the scheduler the ability to predict the impact of its decisions on the energy consumed by CPUs. EAS relies on an Energy Model (EM) of the CPUs to select an energy efficient CPU for each task. Allowing to save up battery even further. EMS aka Exynos Mobile Scheduler, is a fork of EAS for Exynos. We ported to our 4.4.y kernel. As written above, EMS kernel is good for battery saving. Some words from kernel official docs: - EAS operates only on heterogeneous CPU topologies (such as Arm big.LITTLE) because this is where the potential for saving energy through scheduling is the highest.
EMS kernel + pwrutilx governor is very good at battery saving according to our test.
Reference about HMP kernel:
It's just the stock scheduler that comes with stock kernel. Basically it's the normal kernel.
What kernel variant to flash once inside AROMA installer?
1) AOSP Legacy Q/R/S - If you are using an old Eureka ROM which was released before February 2022, choose this.
2) AOSP Q/R/S (New) - If you are using an Eureka ROM built as from February 2022, choose this.
3) OneUI 2 - For any OneUI 2 roms (stock/ports).
4) OneUI 3 - For any OneUI 3 roms (stock/ports).

Hi, this kernel has been tested and working fine on A30 devices. Do not come and say that its not working on A30 DEVICES. Its you who is getting an issue, not other A30 users.
If you didn't follow the instruction given in twrp which says to flash magisk 20.3.zip after flashing the kernel, then don't complain.
Now about this magisk20.4 issue. A fix has already been found and the next update will fix this.
Thank you.

Hi there once again, first and utmost I appreciate your hard work on the Kernel.
I was so frustrated after a few hours of testing and trying to get it to work without any fruition..
I also wanted to ask if it is possible to replace kernels or not, and if it is possible would you provide instructions to replace the kernel I have at the moment with yours? in addition, I'm running Havoc OS 3.8
Thank you.
Edit1:
Thanks! i got it to work! ^^

Hi
Overclocked frequencies can be changed in hktweaks app ( link in thread)
You will notice that some overclocked frequencies are not used. If you want max performance, then set CPU governor to userspace and set min and max Frequency of both big and little cores to same value

How often will you update this kernel?
I won't release updates often, but i will still update source and
you are free to compile it yourself.
/*

Is my ROM/device supported?
As long as it is OnePlus 8T or OnePlus 9R, and as long as your rom is based
on Android 12, then yes, it is supported.
/*
* .NOTE:
* .OnePlus 9R has not been tested, so I do not guarantee its full support.
* .The same thing goes for Android 11 ROMs (including AOSP one(s))
* .as i did test only on Android 12 AOSP ROM.
*/
Which toolchain did you use?
• Compiled with latest cutting-edge LLVM-Tools-14 (https://llvm.org/docs/ReleaseNotes.html), with LLVM_IAS (integrated assembler), with Clang compiler (refer to https://clang.llvm.org/) and with LD.LLD linker (LLVM linker, refer to https://lld.llvm.org/) to have increased performances and smaller zImage (aka kernel Image) size (which is around ~50MB, compared to the over ~100MB Image of other kernels.).
Toolchain link: https://github.com/ClangBuiltLinux/tc-build
Features
• Compiled with Full LTO (Link Time Optimization, https://llvm.org/docs/LinkTimeOptimization.html), which makes kernel Image bigger than with ThinLTO but also increase performances by a lot (https://docs.google.com/spreadsheets/u/0/d/1mhjyshujZz8jYI7dMoCe-yFbxymW-fWaC08vMhBbEmQ/htmlview).
• Compiled with CFI Clang (https://clang.llvm.org/docs/ControlFlowIntegrity.html) and with Shadow Call Stack (SCS, https://clang.llvm.org/docs/ShadowCallStack.html) to improve security by a lot, but with a little less performance and a little more overhead (around ~1% of overhead, https://source.android.com/devices/tech/debug/shadow-call-stack).
• Disabled STune (SchedTune) in favor or UClamp (UtilClamp) to achieve less jank (jitter) and less fps drops (refer to https://www.linuxplumbersconf.org/e...hments/328/552/UtilClamp_usage_on_Android.pdf).
• Disabled WALT in favor of PELT, even if benchmarks clearly say that WALT is better, i did not see any lag or latency issue (refer to https://www.slideshare.net/linaroorg/walt-vs-pelt-redux-sfo17307.
• Upstreamed F2FS (/data filesystem) to latest (5.16) available mainline port for linux 4.19 (https://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs-stable.git/tag/?h=5.16-rc1-4.19).
• Upstreamed EXT4 (/system, /vendor, /odm, /product filesystem) to latest commits found in linux mainline.
• Use EAS (Energy Aware Scheduler) along with Schedutil governor to improve battery backup and keep high performances.
• Improved cfq I/O scheduler to reduce jitter by a lot.
• Disabled some debugging and tracing features such as Coresight (https://developer.arm.com/ip-products/system-ip/coresight-debug-and-trace).
• Disabled most debugging functions treewide to achieve less overhead and a smoother experience (as debug prints logs in dmesg, there may ve high I/O Disk usage, leading to a notable performance lose): Android binder, mm, drivers, ion, techpack drivers...
• Built qcacld-3.0 (network driver) and most techpack drivers as user and disable useless debug.
• Compiled with LLVM-Polly up-to-date flags to tweak LLVM-Tools and so to get smaller Image and better performances (refer to https://polly.llvm.org/ and to https://polly.llvm.org/performance.html).
• Tweaked UDFPS (Under Display FingerPrint Scanner, aka FOD, Fingerprint On Display) to faster unlock experience (https://github.com/FraSharp/kernel_oneplus_sm8250/commit/6fbf5a20fc78f954818649eb9048a63077bc0f0f).
• Disabled many unused configs to reduce kernel Image.
• Compiled some kernel parts with -Ofast to increase performance on critical points, such as fingerprint and display (https://www.phoronix.com/scan.php?page=article&item=gcc_47_optimizations&num=2).
• Upstreamed kernel to latest ACK (Android Common Kernel, https://android.googlesource.com/kernel/common/+/refs/heads/android-mainline) tag and to latest CAF (Code Aurora Forum, https://source.codeaurora.org/quic/la/kernel/msm-4.19) tag to address latest CVE and to improve kernel treewide.
• Built vdso32 to get better battery backup and better performances according to Google (refer to https://source.android.com/devices/architecture/kernel/config#vdso32-on-arm64)
• Fixed PD (Power Delivery) charging, you can now charge phone with your laptop now at a reasonably good speed (~1400 mAh, tested with OnePlus warp cable and MacBook Air).
• Disabled pstore (logging and debugging feature) as it doesn't work.
• WireGuard VPN tunnel support and upstreamed to latest commits from mainline (https://www.wireguard.com/).
• Upstreamed ZSTD and LZ4 compression algorithms to latest commits from mainline.
• Tweak scheduler to achieve less overhead and better latency (lower).
• Added USB-2.0 fast charge upto ~900mAh (https://github.com/FraSharp/kernel_oneplus_sm8250/commit/1669d653a321f8a491df02b42f5a472fa177db9e).
• Added better number generator, LRNG (Linux Random Number Generator) (https://www.chronox.de/lrng/doc/lrng.pdf).
Very cool, you put some random features, but how to install this?
First of all, make a backup!!! I don't want to be blamed if you lose your data.
1. Download kernel zip from the link in thread.
2. Now you have 2 ways to flash this:
.A) Use Franco Kernel Manager (https://play.google.com/store/apps/details?id=com.franco.kernel&hl=it&gl=US)
.Go to flasher and then press on "Manual Flasher" button, select kernel zip and press "flash and reboot".
.B) Use adb sideload from recovery: Press on apply update, adb sideload, and then execute this command within pc's terminal:
Spoiler: command
adb sideload <drag n drop kernel zip here>
.If you get "Signature verification failed", change recovery.
3. Flash dtbo with
Spoiler: command
fastboot flash dtbo dtbo.img
/*
* .NOTE:
* .This is an AnyKernel3 zip, so you won't need to
* .flash Magisk again if you have it installed.

Note: Custom kernels are NOT supported unless the kernel says it supports PA and GMS is included!
this is a part of text found in https://forum.xda-developers.com/t/paranoid-android-ruby-beta-4-oneplus-8t.4206613/, it goes the same for aospa sapphire
hey,this kernel battery saving or performance?

it is a little more focused on performance than battery, but battery backup is very good
I really want to try this on Havoc but Havoc is still on android 11. I'm a bit scared, i might break my 8T

it should boot, at most you will have some casual bugs (most likely non working wifi, but it's very unusual to happen), anyway it won't damage for phone. in the worst case it won't boot and all you have to do is reboot to recovery and flash a working kernel

flash dtbo in fastboot first and flash kernel in recovery via sideload,right?
Ohhh i see thank you so much! I'll update if it works on Havoc Os

It booted on HavocOS 4.12, no problems found on a quick glance, however on a startup "there was an internal problem" notification popped up.
OP - you might want to include dtbo.img in kernel zip, as AnyKernel3 handles flashing dtbo too (it worked when I copied it), no problem with flashing using OrangeFox Recovery.

good about the no issues on android 11, the internal problem popup is there and we can do nothing about it , i didn't know that AnyKernel3 handled dtbo, so thank you for letting me know that, bye.

@Immortalis tried on HavocOS 4.12, as you can see from this post:

Hello OP, I'm going to try this on Havoc OS 4.12 (Android 11). If i'm going to flash using EX kernel manager or FKM. Do i still need to flash dtbo?

yes you will need to flash dtbo in every case
This booted on my 8pro without dtbo
