OFFICIAL FEATURES OF EUREKA R9.0

→ Upstream Linux Kernel Version from 4.4.288 to 4.4.302 (latest and last update from Linux).

→ Implemented EurekaSound (ESOUND) v1.0, a basic headphone audio controller (For AOSP only).

→ Implemented Eureka Display Control (EKCAL) which is based on Samsung mDNIE driver (Not available for A20e).

→ Modified DT2W driver for A20 and A40 so as to fix DT2W issue on AOSP ROMs.

→ Fixed all remaining warnings in kernel source.

→ For permissive selinux, selinux can be switched to enforcing after boot.

→ Further improvements to SElinux code to fix some warnings in kernel log.

→ Fixed custom flashlight controller for A10.

→ Updated WireGuard VPN driver to latest version (1.0.20211208)

→ Merged 98 % audio and camera changes from R kernel source into Q/R/S (AOSP/OneUI2) kernels.

→ AROMA Installer is now used to facilitate the installation of Eureka Kernel.

→ OneUI and AOSP kernels & custom DTBs have been merged into 1 zip (kept size as small as possible).

→ Built with Vortex Clang & LTO which is based on the latest version of Clang 14 (20220201).

→ Two kernel versions with different schedulers are now available:
→ Implemented EMS (Exynos Mobile Scheduler) which is a scheduler based on EAS (Energy Aware Scheduling).
→ The normal kernel version has the stock HMP (Heterogeneous Multi-Processing) scheduler.

→ Eureka kernel R9.0 heavily depends on DTB (not DTBO) for the following features:
→ CPU and GPU overclock & underclock
→ SELinux state (enforcing or permissive)
→ Sound driver compatibility (AOSP, OneUI2 or OneUI3)
→ Energy model and parameters for EMS kernels

→ EMS kernel works best with schedutil based governors. The following governors were added:
→ Blu Schedutil
→ ElectroUtilX
→ PwrUtilX

→ Updated to latest A305F kernel source (A305FDDU6CUI3).

→ Time left for full charge is now shown on OneUI ROMs.

→ Updated all DTBOs to match latest changes from R source.

→ Possible fix for issue of glitched video renderings on social media apps (E.g: Instragram) - reported by our testers.

→ DTC (Device Tree Compiler) on kernel source has been upreved to 1.6.1, latest available

→ Updated spectrum files.

→ Other minor changes.

→ Skipped R8.5 xD
