如何打包dtbo呢 写入入dtbo分区呢 cat 多个文件可以吗

Hey there,
new kernel sources were released by samsung, but I can't seem to find an updated cruel kernel. Any hints?

Thanks

如何编译kernel 给TWRP 正常编译得到的image 替换recovery.img 无法开机

@evdenis you need to update the file for github actions to install ccache.

I compiled v3.10 (+magisk 21.4) which works great on the N975F with stock Android 10 TH7 base.
When I am flashing the same compiled kernel on Android 11 (N975FXXS6EUA1_N975FOXM6ETLL), it doesn't boot.
Is this kernel compatible with Android 11 bases? If so, how to compile it for Android 11?

Thanks

I tried to install one from releases on my G975N runing GULB but it failed. Then I tried to built my own but it says unknown model. Is G975N model not supported?

cpu governor "conservative" and "ondemand" crashes the system. it freezes for like 3 seconds and crashes, and bootloops once (only once), then reverts back to schedutil. performance, userspace, powersave and schedutil is fine. i am on a S10e SM-G970F running stock rom, latest kernel and update.

here is my build config:

          ./cruelbuild config                    \

Hi,
Is there any particular reason for not supporting new Magisk version? I'm not into kernel building for Android, but I'd like to know how much changed for a kernel to support it.

Thank you

Look at how these patches could be adopted:

1. Kernel/sched: Reduce latency for better responsiveness c750d28
2. mm: Decrease swappiness to 8 9948bf1
3. "block: set readahead to 512 " df5ce79 or "mm: set 2048KB as default" 2e0285b
4. "fs:dcache Reduce vfs cache pressure to 50 " 573e9b9
5. "drivers/mmc/core- Add better CRC control " e1e637c

Hi, meybe any people making or make for me Kernel , OneUI 4.1 Android 12 HVE5 please, i try it six uhrs and dont can make ;(

编译make内核后 用mkbootimg.py替换kernel生成 recovery.img 写入recovery分区就无法进recovery了
试用用原来的kernel从新生成镜像写入recovery 又成功进入了
配置文件用的是 进入recovery 提取 /proc/config.gz

Hellow everyone, having troubles with magisk v26.1: bootloops randomly if I reboot my phone and needing to clear data and deal with apps restore.. going back to Cruel kernel with magisk v25.2 makes the phone more stable. I wanted to fork the repo and make some tweaks and build it like I always did, however whenever I commit the +magisk=v25.2, it always fails to build and throws several cautions, here is the compiling log before the build stops:

May I ask you if we have the latest kernel sources to merge with 4.4? Thank you in advance!
Also, is there an option to not specify if selinux will be permissive or enforced, and decide it via software?

Thank you

Los?
Samsung firmware?

Hello,
I compiled cruel enabling powersave, conservative, performance CPU Governors.
I checked the /sys/ properties to see if they were actually enabled, and they are.
Whenever I try to change the governor to anything different from "powersave" or "performance", my G975F Immediately restarts and goes back to schedutil.
Are the other governors actually implemented?

Thank you.
