    new rainbow kernel V1.1
    based on a125f latest samsung source

    -add dtb.img
    -overclock cpu:
    -BIG cores 2351 to 2501
    -LITTLE cores 1800 to 2000
    -CCI 1051 to 1265
    -overclock gpu 6800 to 8970
    -added CRC32 optimized rountine
    -upstream LZ4
    -upstream linux string rountine
    -added TRANSPARENT HUGEPAGE
    -fixed mtp for GSI
    -fixed Touch for GSI
    -fixed rcu performance
    -added optimized checksum rountine
    -removed knox and others security features
    -added cpufreq governors ondemand and userspace
    -added driver power suspend 2.0
    -optimized EXT4 partision
    -fix touch in gsi
    -removed erratum not used
    -added jump_label
    -kernel optimized for more performance
    -and other minor optimizations
    -compiled whith proton clang-13/llvm + polly + thinlto + O3 + cortex-a53 optimization

    if you think the old version is better you can use

    old rainbow kernel v-4.0 (just gsi)
    based on a125f old samsung source

    - 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)

    old Source code:

    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

    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

    - 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

    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
