[EOL][KERNEL] [OnePlusX] [OOS 3.x.x/2.x.x] Boeffla-Kernel (12-06-2017)

Hi all,
some of you know me from the other OnePlus (One and Two) or Samsung devices areas, where I provide my kernels already for more than two years to OnePlus One, OnePlus Two, Galaxy S5, S3 and Note 10.1 users for all sort of platforms (Samsung, Cyanogenmod, Omnirom etc.)
Please note:
I am not heading to have as many features as possible implemented, this is not my design goal. If you are more into that, move on to other kernels. If you are searching for a good mix of improvements and new functions while not sacrificing stability, you are welcome here (see below the history section for more info).
Compatibility
Important: This kernel is only meant to be compatible with official OnePlus OOS and nothing else.
So when the kernel does not run on custom rom XYZ, do not even bother me with it or ask hundred times in the thread for compatibility.
I could not care less about it !!
Important notes
]When using new anykernel concept Boeffla-Kernel: Flash stock kernel of rom first !
Make sure you flash the correct kernel version, depending on whether you really use Oxygen OS or a different OS !!!
Also note: You have to use Boeffla-Config app which I provide on my homepage to tweak the kernel. 3rd party apps will not be able to unleash the full power of the kernel.
Saying that, the Boeffla-Sound app in Play Store is not designed to work on the OPX, neither was it developed by me, hence it will never work on the OPX ever. Boeffla-Config is the way to go here !!!
Support
First read the FAQ section on the Homepage !!!
Click here to learn about all possible kernel settings in the config app (quite outdated, as it is focused on S3 still).
Click here to learn about using the config app (quite outdated, as it is focused on S3 still).
I will refuse to give support if you do any undervolting and experience freezes or hot reboots.
I will also not provide any support if you do not use Boeffla-Config app to tweak the kernel, other 3rd party tweaking apps are known (and intended) to cause issues.
I will refuse to give support if you have xposed framework installed and reporting any kind of weird issues. My opinion to xposed it quite clear: too powerful for >90% of the users that just mess up their system with it.
Otherwise, you can get in touch with me via the support e-mail address: [email protected]
Please provide kernel version, rom version, a detailed issue description and ideally supporting screenshots or log files.

History and design targets
Basically I created my first Boeffla-Kernel in 2012 as there was no kernel for the Samsung Galaxy S3 around that had exactly the mix of functionalities that I wanted. I wanted to have full flexibility in undervolting and charge rates for instance, but did not like the sharpness and/or brightness tweaks many kernels have implemented as per default.
Hence, I began to create my own kernel after a while, adding all the features I like. This is the result of my work, which in the end I decided to share with you. I hope you like it as much as I do.
The objective of this kernel is to have a kernel for daily use. It does not aim for best battery life, or best smoothness or best benchmark scores. Also it does not aim to have the broadest feature set available everywhere.
It aims more for a good mix of all, not sacrificing stability and functionality in the end.
And - most important: It aims to stay quite close to stock !!!
These design targets are also valid for the OnePlus kernel here!!!
This said, I will definitely NEVER implement:
things I do personally not need
things I do not like
things that are in any way dangerous
anything which is highly experimental
f2fs - it is known to cause various issues and compatibility problems
custom hotplugging algorithms
a CAF based kernel
anything that requires upstreaming of kernel parts to a higher kernel major version
So do not even ask for it if it falls into the listed categories. Everything else I am happy to check and decide.
And: I do not really care about benchmark numbers, they say almost nothing as long as something is not completely wrong. Important for me is the feel-good factor.
I am also not interested in gaming at all, so never expect a gamer kernel. It will just not happen...
Compatibility
To reiterate it again: Flash the correct kernel depending on whether you are using Oxygen OS or another rom !!!
Configuration of the kernel
To tweak and configure the kernel, manually load and install the app "Boeffla-Config V2" from the downloads section on www.boeffla.de.
You need at least version 2.2.29 or higher for the OnePlus X Boeffla Kernels.
Donation
If you like my work, feel free to donate: Donation-Link
If you donate at least 2,49 EUR (to be in line with the donation app prices on Google Play store), you will receive a personal donation code which unlocks some nice little comfort functions in Boeffla-Config V2 on top.

All sources can be found in my Github repository: http://github.com/andip71
Credits to developers
Of course, I had never been able to create all that by my own. So I want to give credits to the really good developers around, that have given me all the inspiration and from which I cherry picked lots of the implemented functionalities:
* ZaneZam
* Grarak
* Yank555
* Hardcore
* Chainfire
* AndreiLux
* Netarchy
* Gokhanmoral
* Simone201
* Mialwe
* Entropy512
* Faux
* Harunjo
* FranciscoFranco
* Ak
... I just hope I did not forget someone. If so, please let me know and I will add you of course.
Thanks to all of you for your great work !!!
Disclaimer
*** As always - Flash on our own risk! ***
Make sure you flash the correct version depending on your firmware version!
I can and will not take any responsibility for bricked phones or lost data.
It is generally recommended to run a complete Nandroid backup in your custom recovery and safely store your personal data before you flash a new kernel.
Cheers and enjoy

*** You want my support? Then stick to my rules ***
Guys, I am receiving more and more completely useless support requests in different threads. Useless because people provide nothing to be able to help, not even the minimal possible information they could give.
Hence, I will now remind anyone again on the support guide lines stated here:
http://boeffla.de/index.php/support/support
Also you need to ensure you follow the installation guide lines incl. trouble-shooting stated here:
http://boeffla.de/index.php/support/installation-how-to
And to cut a long story short: If you do not at least provide what I request in the support guide lines, I will IGNORE YOUR REQUESTS IN FUTURE.
Straight and simple. I have enough of people wasting my time just because they are too lazy to write details.
Period.
Also as a reminder:
you use xposed? -> no support, everything is your own issue
you use a custom rom and not the official stock or CM one? -> good luck, you are on your own
you undervolt or overclock? -> have fun, but without my support
Sorry, this might sound harsh (and it is meant to sound harsh), but you cannot imagine about how crappy support requests can be. Stating something does not work is just not enough.
Please consider that!!!
Andi

Great to have you here

Welcome Andi !!! Gonna flash your kernel as soon as I get my OPX .... Will make profiles for it too
Welcome again !!!

sorry if i sound like a noob but if i have bluspark kernel already flashed, can i just flash this ontop of it? or do i have to restore a backup (of the opx before i flashed bluspark) and then flash this kernel? thanks in advance

Thanks a ton. Is CM support planned?

You can flash on top of it as Boeffla kernel works on a different principle (Sorry.. I forgot what it is called... LOL... Maybe Andi can tell) .... But yeah, if issues come, flash stock and then the Boeffla (shouldn't happen though )

I don't wanna post on behalf of Andi... But if you have been following Andi , he usually builds for CM once official builds roll out with everything working... For now, there is no official build, though almost everything is working now...
But Boeffla is in initial phase of development for OPX so I feel lord will focus more on Oos...
In short, don't expect a CM version till official nightlies start.

Nice to see boeffla kernel here. Was waiting for this after seeing a thread on oneplus forum. Is there a version for cm12/13 as well?
Edit: Never mind

Finally, I can't wait to flash it. You're the best, Andi, I'm proud I can say I designed your avatar, hahaha.

well i tried to install, and it gave me the error : your device is onyx. this zip is for ONE
i did install this zip: boeffla-kernel-4.0-beta1-OOS2xx-OnePlusX.recovery.zip
can anyone help/has the same problem

Which recovery did you use ? As can clearly be seen, this issue is from Updater-script .... So either you can delete that line from the script or best is to use another twrp

You downloaded the wrong kernel ( you downloaded the OnePlus one variant) so don't flash it as it might brick your device.
Scroll a bit more down in the Web page till you find OnePlus X.
P.S. The website can be a bit confusing for newer members, so here you go.

no it was the opx variant, as the filename showed opx when i flashed it. thanks anyway, and yeah the website is a bit jumbled
but the problem was an old twrp version. updated it and the kernel flashed no problem . BTW i like ur icon pack, might try it

Can someone explain the difference between this kernel and blu-spark to us common people?
What do you take into consideration when deciding which one to use?

Hi Andi,
Good to have Boeffla kernel again!

The real deal just came to opx. Thanks, bro! Hope opx gets official cm so you can provide support for cm too, as I cannot live without cm.

[KERNEL][HI6250] Veno Kernel [2017-05-22]

Veno Kernel for Huawei HI6250 devices​
Note: I'm waiting for Huawei to release new kernel sources with Nougat, until then I'll focus on fixing any bugs people find. New features will come with Linux 4.1.
The goal​To provide better battery life and more smoothness to your everyday experience, but without sacrificing one in the name of the other (so no +smooth/-battery tweaks and vice versa).
Maybe some extra features? I don't know, I hate unnecessary bloat that provides nothing to everyday user (or even developer).
Okay, so what's in?
Based on latest Huawei VNS sources from January 2017
Turns out newest sources are unstable, I rebased the kernel on 2016 release
Patched to 3.10.105 upstream
Built using Linaro 6.3 toolchain
DM Verity disabled
UKSM 0.1.2.6 (backported from Linux 4.0)
BFQ I/O scheduler
ROW I/O scheduler
Thunderplug hotplugging driver*
Dynamic Fsync
AnyKernel2 package! Compatible with any ROM except stock newer than B336.
For full list of changes see here.
* - Thunderplug is out for now, as it made the device unstable​
Installation​
Make sure you have TWRP installed
Create backup of your current boot
Flash the zip package (it will modify your boot instead of flashing entire boot.img)
Reboot and enjoy! Look below for how to use additional features
THAT'S A LOT OF CHANGES, BUT I HAVE NO IDEA WHAT I'M READING​A quick ELI5 then:
Patched to 3.10.105 upstream
Newer source = less bugs and better kernel in general.
Built using Linaro 6.3 toolchain
Kernel has extra ARM optimizations and phone is faster/has better battery life.
DM Verity disabled
Big brother won't know that you have fiddled with root.
UKSM
More free RAM and less CPU load, so MORE RAM, PERFORMANCE AND BATTERY LIFE.
BFQ I/O scheduler
ROW I/O scheduler Schedulers
With default settings phone will run smoothly even when you're playing FLAC music, compressing 10 archives of 5GB of music and banging your gf (I can't actually know that)
Dynamic Fsync
When you're using the phone, it cares more about your smooth experience than writing data to disk, so the system seems more responsive.
AnyKernel2 package
Can install on top of anything, Huawei is upgrading to kernel 4.1 with EMUI5 though, so flashing might be going backwards (this is 3.10), at least until they release new sources.

Latest release: 2017-05-22
Download: https://www.androidfilehost.com/?w=files&flid=161384

20170406
Rebased on older, more stable Huawei sources (from 2016, everything else is the same)
Removed some of the debugging stuff from the kernel
Enabled Huawei hotplugging driver (it appears to only control big cores tho?)
20170405
UKSM patched to v0.1.2.6 again
Enabled/Disabled a lot of stuff in defconfig
Disabled mostly debugging stuff, which should result in slightly faster kernel.
Enabled a lot of USB drivers (so most stuff should work with Host Mode, if anyone ever uses that)
Enabled some missing Huawei code from older kernel sources, which I believe caused lowmem killer to go haywire, causing heavy apps to randomly close (I tested this one a bit, apps like Snapchat seem to no longer close, can never be sure)
20170404 - BUGFIX attempt
Rolled UKSM back to v0.1.2.3, should help with apps closing without any error
20170330
Removed Thunderplug, as it was causing freezes and bootloops (Huawei HMP doesn't like to have cores offline apparently), system should be stable now
Hotplugging will most likely return, with different driver or when Huawei releases 4.1 kernel sources.
My birthday release, yay, have a stable kernel everyone
20170329
Fix multiple lcd_notify calls
Protect against some hotplug race conditions
Run Thunderplug in per-core mode by default (gotta save the energy!)
Dynamic Fsync (ported to lcd_notify)
Fixes to backported UKSM (possibly fixes binder errors, apps not opening until reboot)
20170325
Initial release

Works with LineageOS 14.1?

Yes, I'm running it on LOS 14.1 right now.
If somebody could test it on stock and EMUI5 ROMs (just for the heck of it, keep backup) I'd be grateful.

Installed succesfully on L31 running Resurrection Remix nougat. I will try for a few days and report back feedback

Will try it on EMUI 5 as soon as I have time.. very happy to see our device is getting devs' attention, keep up the good work!

Good afternoon. Your modification will work on EMUI 4 ?
thank you
upd.: on EMUI 4 it worked

Hello
I have tested on vns-l31c636b361 (nougat), it does not start blocking your device is booting now ....
(I think I forgot the root)
I will re-try with but I get it with dload c636b170.
New try, l31c636b170 (emui 4) + twrp meticulus, ok :good:

Flashed it more than a day ago, working great on LineageOS 14 (VNS-L31), yet to find any issues...

Wat does it really do haha? Saw "whats in" but dont really know what that means hahaha.

Are you planning to add other CPU/ GPU governors?

It's something I'd like to do at some point, but there are very few governors which are properly adapted to octacore devices and none so far worked out of the box with Huawei kernel. I'm keeping my eye mostly on ElementalX and Impulse, but they'll need changes to even compile.
For now stick with interactive, next release with thunderplug enabled by default will bring better battery life.
Sent from my VNS-L21 using Tapatalk

It's really nice to hear that you are working on it. Thanks for your reply.

20170329 release
New release is out! Note that I wasn't running on a new build for very long, so issues might still surface, keep a watch on this thread.
Changes:
Fix multiple lcd_notify calls
lcd_notifier call was implemented in wrong section of Huawei LCD driver, oops.
Protect against some hotplug race conditions
Stability fixes mostly, based on ThunderZap kernels.
Run Thunderplug in per-core mode by default (gotta save the energy!)
Due to how scheduling works in Huawei kernel, it might keep one or two big cores up after heavy load, but should be fine once the screen is turned off.
Dynamic Fsync (ported to lcd_notify)
I moved Dynamic Fsync (thanks faux123) to lcd_notify to avoid kernel bloat from powersuspend or earlysuspend (which are not present in the kernel).
Fixes to backported UKSM (possibly fixes binder errors, apps not opening until reboot)
My derp in commiting changes might have caused critical fail in Android Binder, which resulted in random reboots and new apps not opening. Tell me if anyone encounters it.
Overall this release should bring much better battery life and smoothness to the system (mostly thanks to dyn fsync).

Settings crash, dialer crashes when dialing any number after flashing latest release.
Anyway to unflash, or fix this? I didn't do a twrp backup prior to this, but I did do a cache/dalvik wipe after flashing.
Will a factory reset fix this? Or maybe just wipe /system in twrp?
I'm running stock b170 on vnsl21, meticulus twrp, rooted with magisk. I also have systemless xposed installed, maybe there's a conflict?

So then, would a fastboot flash boot boot.img work to uninstall the kernel?
edit: I was just about to instal catlog to provide logs, while going for another round of dalvik/cache wipe and guess what - it seems everything is ok now. Will keep you posted if any issues arise.

Yes, that's how you flash kernel images. Also keep backup next time.

Also a question if I may. Would this kernel provide any benefits over the stock one if I don't install Kernel Adiutor and change any of the settings - basically just flash it and forget it?
edit: 2 questions if you could be so kind as to indulge me.
Does this modify haptic feedback? As it seems to me - either that or I'm crazy - that keyboard haptic feedback is different after flashing this. It's weaker and a little strange (?), however, navbar haptic feedback and other vibrations seem to be the same as with the stock kernel.
Thanks for your time
further edit for feedback: The fingerprint sensor is a bit iffy now. It's considerably slower sometimes, and generally slower and doesn't always vibrate on unlock, like 9/10 times it doesn't vibrate.

I flashed today's build and I noticed that only one core was active, and I can't turn on more than 4 cores so I can basically use 2 little and 2 big cores. Is this as it should be expected?

[Kernel] SMF-KERNEL - RR/AICP/LOS/AOSP - 8.1

Hello!
I want to introduce my first custom kernel for the Essential PH-1. This is based of several sources, I cherry-picked commits to make improvements to the stock LOS kernel. I'm not a developer, but i really like to port stuff over .
Kernel is suitable for AOSP based ROMS such as RR/AICP/CARBON/LOS etc... If you want to request for specific features, let me know and i'll do my best to bring them over.
Special Features:
Updated to lastest LOS Stock Kernel
Added a few governors like: cultivation / impulse
added a few IO Schedulers: Maple
Kcal Color Control driver
USB Fast Charge - pending will be added in R2
SafetyNet Patch (Bypass bootloader unlocked check)
Dynamic Fsync control
a little Overclock - will be added in R2
Motorola Quickwake - Will be added in R2
and manny other small fixes (you can check the commits in the sources)

Disclaimer: I am not responsible if you use this and brick your device or if your device blows up, implodes, flames start shooting from it or it kills your neighbor's dog. Flash at your own risk. I am not responsible.... It was the other guy... I swear....
Latest Release: SMF-Kernel R2
Known issues:
05.17.2018 - CPU Freq don't always stick, known issue caused by other drivers. Phone will eventually set your frequencies, dont' panic.
Installation:
Obviouly you have a Unlocked Bootloader since you're running a custom rom (make sure to never lock your bootloader in this state)
Boot into Bootloader (adb reboot Bootloader)
If you want to root flash the "Magisk" version of the kernel, it's been prerooted with the latest Magisk Beta available.
Code:
fastboot flash boot SMF-Kernel-R1-Magisk.img
reboot
If you want to manually root, first flash twrp, then from twrp flash the 'non magisk' version and after that flash the magisk zip.

Looks awesome! I'll give it a try soon!
(For anyone wondering about overclocking the CPU, he committed some changes to the github that would apply this and it should appear in the next revision of the kernel.)

Just installed and so far it's buttery smooth.

Good stuff, thanks for this! Could you tell me a little more about cultivation? I can't seem to find much information online about it
Also a request, if possible vibration level control would be super appreciated

I found Cultivation to be really great in terms of perfornance. It's a little bit agressive with the CPU so you get buttery smooth experience with Screen On but it may cost a few % on battery at the end of the day. The good thing is that it has specific tunables and you can set a low cpu freq for when the screen is off.
Specific details from its developer:
-based off of caf 4.4 commits
-uses per-pcu timers
-use state_notifier for screen off timer
option to set different timer rate when screen off
-improrted fastlane with threshold from blu_active
In regards of vibration control. It should be there. I'm using EX Kernel Manager and i can see the vibration option under "Miscellaneous"

Thanks for this. It's running amazing so far. Performance has been great and I'll see how battery life is, but so far it's great.
I can't wait for further updates. I really wanna see what Moto quickwake is haha

Thanks for the info on cultivation, I don't mind trading some battery life for butter so I'm using it now
For the vibration control, it doesn't actually work/stick. I've tried kernel auditor and EX Kernel Manager. To be fair, so far it has only worked on LOS and I think invisiblek may have rewritten the stock controller or something so no worries if it isn't a high priority haha

I'll take a look at the latest commits but I've used the latest los kernel base so I'm not sure why is not sticking maybe it needs rom support too (not sure honestly) hahaha
I've been testing R2 since yesterday. Will update after y he weekend!

Just out of curiosity, was anything involving the camera done to this kernel? I am now able to record videos without the bug, on any of the affected ROMs, with this kernel.

Nothing related to camera. Are you sure it works with no issues?
What roms have you tested?

So far, AICP and LOS, both with Essential camera app and GCAM port, HD and 4K, 30 and 60 fps where applicable. Issues presented before flashing very consistently, and so far I have been unable to replicate after flashing this kernel.

Sp you were right. Honestly don't know what happened but I installed the latest RR (clean install) put R2 on top of it and bam recording works as you mentioned lol..
I guess it was a lucky strike!

after flashing the kernel with magisk, stuck on "AICP is starting"
is this normal?
update: the phone works but no magisk (pre root) after flashing the kernel.....

Hey!
Have you booted once and setup everything before flashing the prerooted image?
I've had that error but having all set and then flashing the image will get me rooted. Try to see if you can find magisk manager in the apps list from the settings if you do, reboot and there will be magisk

Double post... Sorry

Thank you for the reply.
the phone was running AICP and I wanted root so I flash the kernel. I can't find the magisk manager or in the settings about magisk. I guess you have to clean install from the beginning to get the root. Thank you for the Kernel

Shouldn't. If you flashed the prerooted magisk image try downloading the magisk manager app manually from xda and see if magisk works

[Kernel][11.15.2020][4.14.205][F2FS] Dragonfly for LG G8 Korean / US

Dragonfly Kernel v1.5 for the LG G8 Korean / US
Introduce
First of all, I'd like to thank Metaphysics team for giving the first custom kernel of G8 USA. Unfortunately I'm using G8 - Korean and they haven't released version for the Korean variant yet. I had to learn how to build a kernel for myself based on their kernel source. However, I want to learn more so I decided to compile the kernel from LGE open source. Now, my kernel is quite stable to be released and shared to the G8 community. You can call it the Dragonfly kernel.
Main Features:
- Based on LGE open source LMG820N_Android_Q_v20r: http://opensource.lge.com/osSch/list?types=NAME&search=g820n
- Linux-Stable-Upstream included to latest 4.14.205
- Next-Gen CAF-Tag LA.UM.8.11.r1-02600-NICOBAR.0 merged
- Regular CAF-Tag for SD855 merged LA.UM.8.1.r1-16200-sm8150.0
- Compiled by ProtonClang 12.0.0 with -O3 speed optimizations
- No VLAs
- Magisk included
- F2FS support
EAS related features:
- EAS implementation patched up to latest CAF state
- Disable autogroups and use cgroups for more efficient task placement
- CPU input boost
File System related features:
- Include rapid GC by @arter97
Network related features:
- Wireguard Support (Details)
- Add new TCP congestion algorithm: BBR2, agilesd
Memory related features:
- Include zstd
Wakelock Blocker:
- Add Boeffla Wakelock Blocker v1.1.0
- The most common and safe wakelocks are blocked by default: qcom_rx_wakelock;wlan;wlan_wow_wl;wlan_extscan_wl;netmgr_wl;NETLINK
How to flash the Kernel:
- You can flash the kernel zip file via TWRP or Magisk
- You can also extract the new_boot.img to flash it via fastboot mode
Known bugs:
- You tell me
DOWNLOAD:

Kernel Special Features:
Version Information
Status: Stable
Created 2020-09-16
Last Updated 2020-11-14

Previous versions, e.g. v1.4, don't work with the new TWRP 3.4. Therefore, I use Anykernel from v1.5. I recommend you follow the steps below:
1. Install magisk patched stock boot.img
2. Install new TWRP 3.4 from Magisk Manager
3. Reboot to TWRP
4. Install Magisk and reboot to TWRP
5. Install Disable Verity zip file and reboot to TWRP
6. Install my kernel Dragonfly v1.5
For newer version, i.e. v1.6, you don't need to repeat all steps above. You just want to flash thew newest Dragonfly.
And good news to you guys, TWRP 3.4 supports F2FS so I decided to enable F2FS support in my kernel as well. To make F2FS, please follow these steps:
1. Install my kernel v1.5
2 .Reboot to TWRP 3.4
3. Change file system of /data to F2FS
4. Replace the attached modified fstab to support F2FS of /data
5. Reboot
Note: You will lose your data.
In case you don't know:
- TWRP-3.4.0.0-G820N.zip and fstab.alphaplus for G8 Korean
- TWRP-3.4.0.0-G820UM.zip and fstab.alphalm for G8 US
Give credits to Erick G and @SGCMarkus for bringing TWRP to our phones.

I'll check if I can make a version for LG G8s tomorrow. However, I can't guarantee that it will work for G8s or not since I don't have that phone. @Eduxki Give me your model, e.g. LMG810EA, and your operator / country as well. Is Android 10 available for your phone now since this kernel is for Android 10

thanks for your hard work! i just installed it on my G820N with latest 20s-fw... seems to be working fine so far.
PS: installed it via TWRP, and had twrp re-inject itself into the boot-img afterwards again.... => would be nice if your prepared installer zip-file would not just include magisk, but also twrp (just as a safety-measure to not loose twrp when installing your kernel.
PPS: after your src rebase/update to that 20r kernel source drop, "dragonfly" is working with my 20s-fw image again!! your previous version with only 20a kernel src only worked until 20m (march sec-patch) firmware, neither 20o nor 20s could run stable on that 20a-kernel. gui hung, apps didn't respond etc... thankful that 20s-fw finally runs stable so far on those 20r-kernel updated version.

Thank you for your feedback. Actually in Dragonfly v1.3 I did lots of changes to schedultil based on Pixel 4 XL kernel. However it didn't work well. Sorry about that. In the v1.4, I revert the changes and make other improvement to schedutil gov.
I'll look into the TWRP injection and hopefully it will be available in v1.5 or 1.6. Any other features you guys want, please let me know.

as for TWRP integration: keep in mind that there are also separate versions for INTL vs KOR edition of TWRP, just like with the kernel itself!
further ideas? :cyclops: ... fix touchscreen in recovery => code fixes already exist, check here:

if i come up with additional ideas i'll let u know.
PS: it's been a while since i last modded/hacked/upgraded android kernels :good:
PPS: maybe sth like the ooooold "crossbreeder" mod =>
https://github.com/f1vefour/CrossBreeder ... but i'm unsure if this is still relevant and or working on "10"... as the original code is rather... dated

Thank you for your efforts. Is there a GSI suitable for g820?

- The fix for touchscreen in recovery is added to my kernel.
- I currently have no idea about TWRP. I have ramdisk with TWRP but no magisk. Can you install TWRP and Magisk then export boot.img and give it me? I will extract ramdisk from it then integrate the ramdisk to my kernel.

It can be used, but it can't double-click the wake-up screen, the display after the screen is not turned off, and the vibration intensity is not adjustable. I backup the g820 boot through twrp, which contains magisk. I hope you can use it

[ROM][Unofficial][11.0] EAS powered LineageOS 18.1 ROM for sagit [04/07/2021]

Hi, all
Recently I was attracted by the idea behind the Energy Awareness Scheduler (EAS) model and shared some thoughts on this topic here. But nowadays Android system must be deeply modified to work with the kernel. So EAS powered ROM was born.
I selected LineageOS as a base because of its stability and long term support. All but changes in Changelog are from LineageOS. If there are bugs about tasks/CPU scheduler in some circumstances, please let me know. Thank you.
More info about EAS.
Features
EAS model from Pixel 2
HMP and MSM_PERFORMANCE disabled in the Kernel
"schedutil" as default CPU governor
No QTI boost services in userspace
No power HAL built-in
Issues
Probably none, but "adb root" is enabled by default for testing reason.

I'll try

Couldn't get it to boot with gapps
Managed to do it with newly downloaded binary and new copy, i guess old one was corrupted somehow
Magisk requires manual boot.img patch, not a big problem but would be nice if we can use the zip or the app, also for some reason google play doesnt display many apps because "its incompatible", I edited build.prop to Pixel 2 solve it
And this rom really feels really smooth, good job!

Google contact can't sync. I replaced aosp contact to Google contact.

I don't use Google apps for now. New build is now rebased on LineageOS 18.1. Let's see if it works well with Gapps.

Using your rom atm, so far so good, hoping havoc have EAS too, Anyways thank you for your work and ofc @NeoArian

Good job on the rom so far! Just wanted to check how do I acquire root on this via Magisk? Thanks!

Please follow the official instructions to install Magisk for root access.
The basic steps for root should be:
Extract the original boot.img from the ROM
Install Magisk app and use it to patch this boot.img
Flash the patched boot.img in TWRP
Reboot and enjoy

Thanks for your work!
And can you explain in simple terms, what will the firmware with the EAS give me vs official LineageOS 18.1?

I don't understand your words exactly. But for the firmware, there are no differences between EAS ROM and the official ROM. EAS is just a bunch of schedulers and methods to balance the performance and battery usage.

The thing is when I installed this ROM the recovery became Lineage Recovery so idk what to do right now.
