Development rainbow kernel a12-v4.0

[Manteiga25]

rainbow kernel v-4.0
based on a125f

- more CPU regulators
- The added XOR throttle of the NEON arm can have a performance increase of up to 20%.
- Added boeffla_wl_blocker driver.
- vector optimizations, matrices, loops, parallelism, GPGPU codegen.
-More aggressive link optimizations.
-VDSO32 enhanced for higher performance in 32-bit applications.
-samsung security disabled.
-kernel optimized with -O3 -Fast (higher performance)
- a memory transparency is activated in fast mode (higher performance)
- optimizations for the A53 cortex (superior performance)
- floating point optimization
- branch optimization
-Fixed touch issue for all gsi panels thanks to RE800T warhammer kernel
- Added power suspend 2.0 driver
-I/O and space performance improvements
- Added wireguard module for greater network security
-optimizations for memcmp
- processor cache optimizations
- Optimizations on EXT4 path for better performance
-small optimizations in the RCU
-LZ4 algorithms have been updated
-fixed kernel compression
- various debugs have been disabled
- memory optimizations
-single extension optimization
-some kernel latencies have been reduced
- Added optimized checksum routine (has a 4x transfer rate increase in A53 cortex)
-other small kernel optimizations for ARM64
-overclocking GPU to 780 MHz
-some changes I don't remember

kernel compiled with clang13 / llvm proton + thinLTO + polly + O3 Ofast + cortex a53 optimization (for better performance)

Attention this kernel has not been tested yet if you get some installation error or bootloop send me a message.

About to test, just have to do a few things.
Thanks for your work!

 

[LAST_krypton]

Just flashed it on a rooted stock rom and it ended in a soft brick.

 

[Manteiga25]

Apenas o mostrei em uma sala de raiz e terminou em um tijolo macio.

does not work?

It does not work. After flashing on a android 11 rooted stock rom, ends up in a soft brick.

Dm-verify and knox disabled.

Vou tentar consertar

Translated by GT: I will try to fix

Good to see another dev here

Good to see another dev here

hello i need your help do i have to disable samsung restrictions in kernel to fix bootloop?

 

[Manteiga25]

Good to see another dev here

the kernel i compiled is based on a125U1 does it work on all variants of a12 or only on that variant?

Mine is based on a125f.
I had to use a patch to overcome the strcpy error

 

[Manteiga25]

Não funciona. Depois de piscar em uma rom de estoque enraizada de android 11, acaba em um tijolo macio.

Eu fiz uma nova compilação

 

[LAST_krypton]

Just flashed the kernel, it seems to work. But cpu z reports it like as if i flashed the stock kernel

 

[Manteiga25]

Acabou de piscar o kernel, parece funcionar. Mas cpu z relata como se eu tivesse feito o flash do kernel padrão

Eu não mudei o nome do kernel, então ele tem o mesmo nome do kernel padrão

Change it if you could.

He just forgot to change it in defconfig
