This the stable release for Android OneUI 2.1 ROM

Kernel Changes on OneUI Compared to latest ones are:-

  • EMS [Exynos Mobile Scheduler] with upstreamed changes taken from Note 10/S10
  • Added Triple cores frequency which will help improve power consumption and performance
  • Implemented thermal table of Triple cores frequency for more balanced throttling mechanism
  • Tuned frequencies for balanced performance and battery life
  • More wakelock controls on battery/GPS/Sensors
  • Upstreamed and Applied HPA [High Page Allocation] for proper page managements
  • SimpleLMK is used and updated!
  • Removed conventional LMK from the kernel and PSI is being used along with SimpleLMK
  • Upstreamed Network drivers and Implemented TCP BBRv2!
  • Upstreamed QOS [Quality Of Service] and Implemented CAKE [Common Applications Kept Enhanced]
  • Jump Label is used to make kernel code faster
  • SPF [Speculative Page Faults] which promises for the app launch time, It improves about 15% average. For the apps which have hundreds of threads, it will be about 20%.
  • Fixed little cores can't stay at 2Ghz under load but it will go to 1.95Ghz so prevent little cores getting forced to 1950mhz under load
  • CPU Freq Table now are little cores:- 202Mhz to 2GHz, big cores: 598Mhz to 2.9GHz (~2.88Ghz)
  • Mali GPU is Oc'ed to 598Mhz
  • Tuned MIF table frequency selection for faster responsiveness to load and user interaction
  • Enable GPU Controls & GPU Voltage Control
  • Disable the migration of timers among CPUs to prevent increases realtime latencies and scheduling interrupts.
  • Disabled Audit Selinux as it affects performance under all circumstances. It's also dirty.
  • Using latest GCC Toolchain available GCC11 with latest companions updates applied on top.
  • Upstreamed Binder drivers up to 4.19k patches
  • Kernel is compiled with LTO [Link Time Optimizations] which makes kernel code faster and optimized
  • F2FS is upstreamed to upstream-f2fs-stable-linux-4.9.y branch with latest updates applied [/data only supported]
  • Kernel is cleaned up deeply and kernel size decreased significantly
  • Removed loggings from EXT4 and F2FS file systems
  • Reserved RAM is now much lower which mean more free ram to use!
  • Implement crypto xxhash which is extremely fast, working at speeds close to RAM limits
  • Optimized string routines for AArch64 which improves performance generally
  • Updated SDCard drivers and Wifi drivers to latest available from Note 10/S10 devices
  • Brought from Note 10 and S10 post processing drivers, MFC , scaler drivers and applied to Note 9 kernel ... should help getting better generally on images or videos processing
  • Fixes on wakelock blocker for correct operations
  • DevFreq boost driver applied and used
  • Wifi drivers is cleaned up and improved
  • Knox Samsung crap removed completely
  • Modem driver cleaned out completely
  • Reserved RAM is reduced to 400mb instead of 550mb [Might be small difference on RAM between 8GB Models and 6GB Models]
  • Sound drivers clean out
  • UFS Exynos cleaned out
  • Oximeter/Pulse sensors cleaned out
  • Using latest Kernel sources

FDE.AI is fully supported and working on Zeus Kernel with more benefits and I will never block any of optimization tools as they do provide improved potential performance and more battery life out of not just zeus but also any kernel who appreciate those tools ... those kernel developers who blocks those tools without any reasons or evidence are the ones who wants to take any optimization tools down along with any other who supports them and hence Zeus Kernel supports FDE.AI/L Speed and others fully so Zeus Kernel are under fire from those gangs so don't get misled by them or believe there false information against Zeus kernels, Thank you.
