(for anyone wondering, yes i took a completly random photo lmao)
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.
/*
* .NOTE:
* .If you plan to do so, don't contact me for help
*/
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.
*/

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?

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.

Q&A
What is Energy Aware Scheduling : Go through this amazing thread https://forum.xda-developers.com/oneplus-5/development/kernel-renderzenith-t3659850
Here is a review on the new kernel with EAS : post #184
Q. After flashing the latest build with EAS there is a slight impact on battery life.
A. This is an expected behavior, please do not worry. Let the device go through and drain and then a full charge and another drain. This will allow EAS to settle in and adjust frequencies. After that you will notice amazing battery life.
Q. I am getting partition error while flashing the zip file.
A. Please use the latest TWRP recovery for the P10 Plus. The P10 Plus recovery will work on P10 as well (as reported by some users)
Q. What should I use to modify the kernel settings ?
A. I personally use EX Kernel Manager, but here is a free and amazing kernel manager that works with this kernel

Q. Not able to change Internal I/O scheduler ?
A. This post will clarify why : Post #53

Great to see it up and now I don't have to be quiet about it.

Says selinux permissive, any chance to run it in enforcing mode?

Woooow is amazing ..

I'm running AOSP, 8.1, on US Mate 9, with Magisk but stock recovery. I have backups of kernel and ramdisk. Is there any reason not to flash this kernel with adb rather than installing TWRP?

I'm getting a partition error when trying to flash this. Tried both Blackball's 3.2.1 and TWRP-3.0.3-for_Oreo.img with the same error. Recovery.log attached.
Edit: Used the recovery from this thread and it flashed successfully. Thanks for the kernel!

Here. This one works.

---------- Post added at 05:44 PM ---------- Previous post was at 05:37 PM ----------
Flashed this on Saturday. It's Monday now and I'm thinking of flashing back my original kernel. Although the battery life is somewhat better, my phone lags on this kernel. The degradation in performance is noticeable when it comes to scrolling in general. It also generally lags after turning the screen on for a few seconds (I'm guessing it takes a few seconds to change the CPU frequency back into something higher?).
It's also worth mentioning that my phone restarted itself one time after freezing. (Wasn't doing anything special, just browsing Reddit and it suddenly froze and restarted.)
Oh, and my Antutu score running this kernel is 20,000 points lower than my stock._.
Running on MHA-L09C185B372 if you're wondering.
Thanks for your work though! It's good to see that someone's working on something for Huawei devices.

how stable is it and how did u root it with magisk does hide work and how is the camera quality and does it have dual sim ?
sorry for asking a lot i really want to use AOSP but i dont know if its stable

I'm happy with it. The things that aren't fully working for me are SD card (only files and VLC see it and read/write) and headphones (which aren't recognized except unless I make or receive a call first). Here is a lengthier explanation:
https://forum.xda-developers.com/showpost.php?p=76231795&postcount=23
I did root with Magisk so that I could install the Huawei camera, which now has full functionality and high quality photos. Magisk reports passing the safetynet checks. I haven't had an app crash, or a full crash for that matter in two days of use. I only have one sim so I don't know if the second works; the system asked me if I was using one sim and I said yes, so evidently the OS thinks it supports two sims. I'm much happier with it, won't go back.

Thanks my friend. Finally a custom kernel for our beloved mate 9.

/* Notice */
Both OnePlus 6 and 6T is supported.
Only OxygenOS is supported, but it is likely that the kernel will work with other ROMs. Though you may encounter minor issues.
Feel free to tip me which commits are needed to fix other ROMs.
Unlike my OnePlus 5/5T kernels before, you are free to flash Magisk after installing the kernel. Kernel does not include Magisk by default.
/* f2fs */
This kernel fully supports f2fs for /data and I encourage everyone to use f2fs with my kernel for better performance.
See here as to why you might want f2fs.
TWRP is not integrated to the kernel.
Please use a TWRP installer to install TWRP on top of my kernel.
To use f2fs, download zip files from http://arter97.com/browse/f2fs
Flash f2fs_tools_for_twrp.zip from TWRP. This won’t format your /data partition.
This will replace TWRP's f2fs tools with the latest version and pass the correct parameter to mkfs.f2fs, which is necessary.
This needs to be done everytime you enter TWRP, if you want to re-format to f2fs.
After formatting, or flashing a new ROM or an OTA, /vendor’s fstab needs to be changed.
Flash f2fs_fstab.zip to convert fstab to f2fs again. This won’t format your /data partition.
/* Disclaimer */
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, and if
you point the finger at me for messing up your device, I will laugh at you. Hard. A lot.

/* Instructions */
You can use the zip file to flash the kernel from your existing TWRP recovery.
If you don't have TWRP installed already, you can use the img file to flash the kernel directly from your PC via fastboot.
Both methods will install both kernel and modified TWRP recovery.
You can check if the modified TWRP is installed by looking at TWRP's version name.
It should say "arter97-f2fs".
If you use fastboot method(directly flashing img), you will not pass SafetyNet.
/* Swap variant */
This kernel has a swap variant for memory-hungry users.
- Users with 6GB of memory or heavy multi-taskers are recommended to use the new swap variant
- Ditched conventional zram swap approach and taken zswap+vnswap for more efficient memory operations
- Backported zsmalloc memory allocator from mainline
- Backported zswap compressed page cache from mainline
- Samsung's Galaxy S9 memory modifications merged for better swapping efficiency tuned for Android

Im use arter kernel alot when on hlte. Keep up a good work.

Nice work!

Got bricked or something.
Was on blu_spark. Booted to recovery > flashed rom -> latest blu_spark recovery -> reboot recovery -> flashed magisk 18.0 -> flashed kernel
After this I booted but found that Magisk is not instaled, pressed "boot to recovery" and now can't do enything with phone, it's not booting even wit hard boot (like volume down and power).
Edit: booted, seems like some problems with blu_spark recovery.

@arter97 audio via Bluetooth is significantly reduced. Tryied with Apple AirPods and others Bluetooth headphones but nothing changed. Max volume corresponds to about half of the original volume.

Actually I think there is some problems with Magisk instalation. I had this issue before, and i couldn't boot in to recovery because Magisk wasn't installed.

I always flash TWRP after kernel flashing.
What I usually do:
boot twrp
flash the kernel
flash twrp
reboot to twrp
flash magisk
reboot

Can anyone confirm this kernel working on any custom roms, as yet?

In the notes section of the OP, he mentions flashing Magisk after the kernel. Testers should try that during install. See if it boots smoothly.

This kernel provides many features and a lot of customization.
*To change settings, it's recommended to use HkTweaks by @corsicanu
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

Wow, nice, good job, will try it out!

A520l will try tomorrow

Working Great with pixel experience ROM, I've upped the voltage on GPU and CPUs , Played COD mobile default all is good , used GLtools to get max graphics , and again all is good

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)

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

97117 for me. Going to tinker then have another go. Best score I've ever had on this device though.
Replacing the device soon though

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.

You need A/B Gsi and not A-only, flash OneUI 2 stock fully and then flash A/B GSI without wipe

After Oneui 2 (Android 10) update your device became system-as-root, soo unfortunately you have too flash A/B gsi too boot as system as root

any GSI support ultra wide cam in Q after this time?
cause i cant use mine in P before, or is the experience gonna be the same after all?

How to remount /system to RW on stock rooted (Magisk) image?

Great job @prashantp01, especially U don't personally have A750x device!
Let's hope it is just the first step?
Kernel works great with custom OneUI 2.0 roms

I'm getting problem Booting ExpressLuke GSI's after updating to 10 ( they used to boot fine before one UI 2.0) other gsi boot with your kernal but they are having same problem like no working camera and no Web page loading. Idk what's causing it.

It happend to me to. I think in the script it deletes KnoxGuard and that happens.
There is solution when that happens:
https://forum.xda-developers.com/android/general/phone-locked-payment-service-uninstalled-t4018177
I didn't try it,but if anybody needs it...

Thanks for replying

Excellent kernel I installed it yesterday and today was a very pleasant experience, very good fluidity, excellent battery of the best that I have seen, in multitasking without lag and very smooth, I recommend it.

i have never experienced random reboot. the only issue for miui 12 is that it charge so slow that's why i wanna try this kernel

fingerprint didn't work on xiaomi.eu 20.7.9 MIUI 12 (MengT-R1.6.0-OldCam)
Edit: OMG sorry its because TWRP Tools to remove DM-Verify and Force Encrypt. But I don't know why, because I know issue after use that tools

Anyway xiaomi.eu (MIUI 12) is huge memory consumption,, 500MB free RAM (3GB variant) even use this kernel. on MIUI 11, I get about 1.1MB free RAM. Its annoying because some apps force stop on background like YouTube apps. I hope MIUI 12 officially released.

Hey dev thanks for your hard work, this is very good kernel but there is a problem and I tried it in different ROMs, the download speed is very slow, and when the phone goes in sleep mode it stops downloading. Same with the latest version, is anybody else facing this or just me ??

Wow the lastest get extremely smooth on Xiaomi.eu MIUI 12 stable! R1.6.2 ... Sir I have request. Can you improve multitask ability and doze the useless file system. because the MIUI 12 eat huge RAM.
But anyway I love this kernel!

wifi disconnects with this kernel? I've tried others and they give me the same problem, I don't know where to bang my head

Flash patch to fix wifi

hi! Thanks for the Hard work! I'm still not using but if you could answer my question, it will be really nice <3
I'm on MIUI 12.1 xiaomi.eu 20.8.6 beta (android 10Q) + Orange Fox + Magisk 20.4
I did a full backup of my phone with orange Fox, if thing gets weird, you know.
But 1. Can I backup only the kernel part, and if something goes wrong flashing this, I could just flash the old back?
2. Is it everything working on MIUI 12.1? even Camera? Can I use it for daily usage ?
Thanks for the replys <3 much appreciate

The kernel part is inside boot.img , which can be found in the rom zip you are using.
So anything that goes wrong by flashing a different kernel can be fixed by installing the boot.img as boot image, or in worst case by dirty flashing the whole rom again. In both cases you shouldn't lose the data.
*After flashing boot image you need to re flash magisk.
