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.

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

rainbow kernel v-2.0 not tested
based on a125f

-more CPU regulators
-kernel optimized with -O3 -Fast (superior performance)
- a memory transparency is activated in fast mode (higher performance)
- optimizations for cortex a53 (higher performance)
- now polly generates an OpenMP code
-floating point optimization
-It is no longer necessary to use the AOSP clang
-branch optimization
-kernel compiled with clang-13 proton + polly + llvm + thinLTO + O3 Ofast + cortex a53 optimizations
new rainbow kernel v2.0 update
this update has not yet been tested send me a message if the new version bootloops

    Indeed. Found it to work now. Compiling with clang higher then 11 will result in failure though. On clang 11 all ok
    can i make a correction for you

    Dm-verify and knox disabled.
    Vou tentar consertar

    Translated by GT: I will try to fix

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