Development [r20] arter97 kernel for OnePlus 9 series
- Thread starter arter97
- Start date
What ROM are you running?Simply amazing performance overall over here. I'm working twelves while streaming, etc. I'm six hours in, and battery is sitting at 73%. Very thankful to be running this and for the updates.
Nice, what your custom settings for kernel. Could plz sent me through PM your kernel setting, plz. If you don't mind
I'm running universal GMS doze magisk module but other then that, I have made no adjustments. I'm running the latest beta right now by the way.
You mentioned that you are running Derpfest rom, but when I installed it and run it was ok. However, I did found that speaker quality is not the best and also AOD is too dim for some reason compare to rom likes, crDroid, PA.
Nlsound is what really helped me. You can find it on telegram. https://t.me/nlsound_updates/418

How about AOD brigthness, It seems too dim can't really see until you push power button.
Haven't messed with that too much, I usually just double tap, I have it enabled while charging though and it seems okay. But I do remember that being an issue with always on.
Right, it is possbile for you to sent me Nlsound zip, for some reason my Telegram is not working properly.
You need to use blu spark r91 on OOS12, this kernel hasn't been updated and the dev has stated intentions of not doing so.
What version should I use for a Lineage ROM based on Android 11?
EDIT: This one seems to be working so far.
Had to reboot after flashing before network connectivity but now it seems fine.

12After a lot of test builds, I'm now marking r20 stable.
Please re-read the OP for most up-to-date changes.
Custom ROMs started to rebase their kernel to OxygenOS 12. Those ROMs are not supported, please keep that in mind.

Wi-Fi drivers updated to 2.0.8.29W
Latest exFAT from Linux v5.19 merged
Latest LRNG v45 merged
2022-06-05 security patch merged8New beta release is up: r21b2.
A few minor bugs have been fixed, but the new major change is the removal of BFQ in favor of Samsung's SSG I/O scheduler.
Qualcomm has been using BFQ I/O scheduler for a while now, but its code complexity is quite huge, reaching 10K lines of code.
This unfortunately, translates to more CPU overhead.
With r21b1, BFQ is removed in favor of Samsung's in-house I/O scheduler: SSG.
SSG is simple enough (only 1.1K lines of code) while still having some Android-specific optimizations such as background/foreground separation.
I/O scheduler is a very complicated topic and synthetic benchmarks will not be able to capture the practical effects of one, hence the beta release.
If you notice anything outside of ordinary (e.g., game stuttering, music dropping out, or major lags when updating apps from Google Play compared to r20), please report back.
If all turns out fine, we can expect some battery improvements.
r21b1 had the background profile set incorrectly. Please update.6r20b2 is up and I'm hoping it's the last beta for the r20 series.
Some new CAF tag merges, LRNG v45 merge, v5.4.197 merge, latest f2fs merge, etc.
Notable change perhaps is the removal of zram writeback.
zram writeback was enabled to offload parts of memory to the UFS when it's unused for a long time, but it seems that it can contribute to lags overtime.
It's been disabled for now.3
Well, don't know what did people expect when it was stated by the DEV that OOS12 is not supported and never will be.2
I'm on OnePlus 9 Pro unlocked from OnePlus. I am running latest version of this kernel on top of Derpfest custom ROM. Derp is not being maintained any longer.
I played Diablo this morning for like three hours straight without a single issue. I use some magisk modules like universal GMS doze but not sure if it will make a difference for heat.
I recommend getting all your MSM tool setup with drivers installed where your PC can see your phone in Fastboot and adb if you plan on going the custom route, that way if something goes wrong you can restore your device.
Me personally, this phone has been pretty incredible besides a few issues like not recognizing my DAC.
The phone does get warm, but I haven't had any issues with it overheating. I really have enjoyed the Diablo immortal so far.
I would definitely recommend this kernel though after you make backups to the three partitions for A & B slots which would be six partitions total backed up. That way if you need to go back, you can restore.
I hope this can help, I don't want to clutter the thread, but just wanted to tell you that for me, I wouldn't go back for nothing. We are really fortunate to have such talented devs sharing their work making LemonadeP_#1. -

/* Notice */
OxygenOS 12 is unsupported.
Non-OxygenOS custom ROMs are supported, but your mileage may vary wildly. Most notably, gesture orientations on some ROMs may be inverted.
Custom ROMs that uses OxygenOS 12 kernel, including LineageOS 19.1, are not supported.
This kernel touches vendor_boot and dtbo partitions, meaning you'd need to restore said partitions whenever you're switching to another kernel or stock.
Please make a back-up of these partitions. The installer doesn’t do this automatically for you. Installing the stock ROM with a full OTA restores said partitions as well.
/* 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.

Watermark boosting disabled to fix aggressive app killings (by Sultan)
Workaround added to fix unwanted doubles presses from the power button18A major new testing release is up.
Changes made in this round is big enough that I've decided to name it r20.
While the build has been stable for me, I'm marking this an alpha as a lot changed.
r20a1 marks the first Linux v5.4 based kernel to have MGLRU backported.
MGLRU is a big deal in everything Linux related, especially for Android.
Esper have a great article on what is MGLRU in a nutshell: https://blog.esper.io/android-dessert-bites-22-linux-memory-management-38419756/
TL;DR:
Personally, I've noticed a sharp decrease in swap usage and improvements in general performance.
Besides MGLRU, there are other numerous patches that are worth noting.
I've brought back updated arm64 routines that were once tried in a beta release but removed later due to random kernel panics (mostly notable from Netflix). The mainline Linux kernel have gotten new updates since then, so r20a1 includes that.
Also, some memory patches made by Sultan are also picked, and I've confirmed that those also help improving responsiveness.
With all these memory stuffs going on, I've also changed swap/zram's parameters. You'll notice a difference in how many apps you can keep open, etc.
The excessive RMNET_DFC wakelock that annoyed some users are now also gone by incorporating a fix from Snapdragon 8 Gen 1.
All in all, this is indeed a pretty big release.
I'm expecting mixed feedback, so please let me know how the new kernel behaves.

First stable release15After months of tests, r3 is up and it's a major release that should fixes all major bugs from previous versions and improve performance.
It turned out that using SimpleLMK causes random soft reboots due to page allocation failures.
This kernel reverts back to using the stock lmkd until this issue is sorted out.
You may experience a slight decrease in how many apps you can leave in the background.
Also, random app crashes and freezes are fixed too.
This was specific to OxygenOS, which freezes apps with cgroup and expects the kernel to un-freeze them, but with my kernel lacking that feature from OnePlus, using my kernel led to app crashes and freezes.
This was fixed by forcefully disabling that feature from the kernel.
Some Bluetooth and USB stuffs were also fixed with this release.
Bug fixes alone make this a noteworthy release, but it also comes with nice performance improvements.
With the Qualcomm HDK, I've managed to debug why using Clang 13 leads to boot failures.
r3 has that issue sorted out and now the kernel uses the latest Clang 13.0.2 instead of 12.
Read-write semaphore backported from Linux v5.16 will also give some nice latency improvements under heavy I/O.
These patches are actively being talked in the f2fs mailing list for backporting to older Android devices.
From Sultan (kerneltoast), r3 also has SLUB per-CPU partial caches disabled for better latency.
