What were your default voltages & by how many millivolts could you undervolt at all important frequencies? Post detailed screenshots of SOT improvements in hours

I've tried Fusion Kernel weeks ago with my phone (SM-A225M) with A225MUBS4BVJ1 build, TWRP installed and Magisk root installed. I was expecting this to work but after few minutes of have the Fusion Kernel, the phone system freezes and auto restart, and it get stuck in boot animation (bootloop). Cleaning cache and dalvik-cache didn't fix that.
So i just restored the system and boot using TWRP backups. Does something cause that bootloop?

bootloop (tested on gsi and one ui 4-5)

Should work with all custom AOSP/LOS based ROMs.
It's working great in RR. Thanks !
It's not work in last RR build.
How did you flash this Kernel ? Flashing kernel after flashing ROM ?
I would recommend you should do so:
1. After flashing ROM, please uninstall Magisk 13.3
2.Flashing Kernel
3.Then reflash Magisk 13.3

RR is fine ROM, but in last release it work very slowly. AnTuTu Benchmark test result for kernel default settings is about 60K only. With fastest "gaming" kernel profile in Spectrum App AnTuTu Benchmark test result is about 100K. For comparison, in RR release 20170703 AnTuTu Benchmark test result is 130K and more with kernel default settings.
1) Why do you have to be logged into both XDA developers and MEGA to download this kernel?
2)Why is it nesssary to reflash Magisk to achieve boot?
30 where the heck are thoser files located that you need to delete to achieve 'full enjoyment'?
I will download magisk 15.1 and try again
Is there a RR Version or Download link can support this Kernel? i fink 2 all stuck on boot screen

It's initial release, so it's just compiled from Xiaomi sources. As i said, i don't have this device yet, so i need you guys to test if Xiaomi's sources are complete and everything works fine. If it boots up, then i will add features to it
I'm guessing the kernel should be flashed on top of this rom?

Maybe try manually replace qca_cld3_wlan.ko from the zip file in /vendor/lib/modules/qca_cld3 with a file manager for example, root explorer
Set permission to 644 and reboot

still not working. Here what i did:
1. copy file "qca_cld3_wlan.ko" from WiFi_fix.zip
2. I didn't know where the file should excatly be,so I paste the file in 2 places:
- vendor/lib/
- vendor/lib/modules/
3. set permission 644 for the file in both places - vendor/lib/ and - vendor/lib/modules/
4. reboot
any ideas?

Hello Sir and friends,
I am using Meow kernel with Treble ARM64 A/B arch. Everything's working fine. But I don't know how to test the different between the kernel that comes with GSI ROM that I flashed and Meow kernel.
All I can feel is slick performance.
Thank you for the great kernel.
Edit: add screenshot.
which ROM does this kernel use for ?

This kernel is only supported on AOSP ROMs. If you flash it over MIUI or GSI ROMs, do that at your own risk.

The Umbrella kernel is basically stock kernel with a few fixes here and there, it's built with GCC. While the Umbrella Mod kernel has many extra features alongside the fixes, it's built using Clang.

Mentioned kernel, is not umbrella, but a relaunched or renamed version of old GPUCode's kernel. We have four forks here (excluding your one), GPUCode one (stopped), relaunched one, umbrella, and umbrella mod. The question is, what's that relaunched kernel there and what are the differences with umbrella mod...?
Great thanks

I was talking about the forked one. The one you linked one is basically the OG Umbrella kernel but with some patches applied for A11. While the Umbrella Mod basically that but with extra features and mods

DOWNLOAD KERNEL ZIP
Kernel Flasher/FKM download configs: oos | custom
(No mirrors please)​
Setup and troubleshoot: To install just flash the zip on a stock setup with either TWRP or autoflash kernel app.
If you come from other kernel or have any issues, you should restore your stock boot.img/vendor_boot.img or dirty flash your ROM before flashing blu_spark zip to avoid problems. Also uninstall or clean data of any kernel control app you're using.
If you are upgrading between blu_spark versions, just flash the kernel zip.
About bugs and reports: don't bother to post if a log isn't ready or without steps so the behavior can be replicated. I only active support stock OOS ROM with NO mods whatsoever (apart from root). That includes NO support if using xposed, Magisk with added modules, etc.
If you're using custom ROMs (including stock based ones) and OOS Open Betas you're much on your own. I'm mostly interested on debugging stuff in stock and stable OOS.
Also try not to spam the thread with OT. There's threads for all kind of stuff, use them.
Going back to stock: This kernel installer doesn't change your filesystem. You can backup your boot.img/vendor_boot.img with TWRP or kernel app before flashing blu_spark if you want to go back to full stock or just dirty flash your full ROM.

Don't forget to hit thanks, it's free
OnePlus 9 Pro development unit donated by OnePlus. Big shouts to them
Very proud for being on the OnePlus Developer Program, special thanks to dev relations team.
blu_spark_r23 release
First blu_spark build for the OP9 series is up
This kernel is tested for the 9 Pro but it's unified, so should work for the OP9 also (need some fixes since code is broken). So backup you boot if you want to test and let me know
Kernel already have some merged goodies and I think I have a good base to work with. For a couple days of work, it's not bad
I'll take a look into more stuff to come, some things in OP are WIP. Stay tuned!
You can use FKM download kernel feature, just import the links bellow in the app.
FKM download configs: oos
Changelog:
Build with Google Clang 12.0.5 + LLD linker
Synchronize codes for OnePlus 9/Pro Oxygen 11.2.6.6.LE25AA
Several build error fixes and quirks handled
Compilation improvements an cruf removed
Some goodies already merged like filesystem stuff, cpu governor & boost/msm perf, TCP algos, wakelock blocker, vibration and haptic feedback control, gpu adrenoboost, etc
All drivers builtin, wifi stack and datarmmnet merged from CAF
net/wireguard: merge v1.0.20210424

Keep in mind: I will give no active support for custom ROMs (including OOS based ones).
I am mostly interested on debugging stuff in stock stable OOS (with logs and reproducible steps to replicate the issue).
No mirrors please

Thanks for the kernel, don't suppose you are still doing TWRP builds?

Changed the one in OP but forgot the one in the release post xD
Just flashed and going to test on stock settings for the next 2 days! Thanks for this I ran your kernel on the 7t pro!
@eng.stk I think the kernel has the same issue as Omega had, wireless charging seems to stop at 95%
Dumped out some logs if it will help
EDIT : OK, Apparently I'm talking crap, just seemed to be charging slowly but did get to 100%
Does anyone have stock kernel?

If you need to revert to stock, extract and flash it from the OTA update in the pinned thread (follow LineageOS's instructions on how to do that), or just flash the magisk patched one in that pinned thread.

I inject some runtime changes via Magisk systemless, so to get full stuff you need root.
Got some laggy sound with YouTube vanced off screen playing background music/ video. Attached log for info. Never happen with stock and omega kernel b4. Thanks
