Eureka R7.5 (R) for A Series

-> Same changelog as 7.5 (Q/R) release. This version is only for roms using R vendor. For the time being, only oneui 3.x uses such vendor.

Eureka R7.5 (Q/R) for A Series

→ Upstream Linux Kernel Version from 4.4.270 to 4.4.277

→ Enabled back 208 MHz frequency for big and little cores.

→ DTB is now used to customize Eureka features such as CPU and GPU frequencies.

→ DTBO is only used to disable dm-verity as from now. You can restore stock dtbo if you have slow charging issue. [Warning: Stock dtbo has dm-verity and you might get BSOD if you do not patch it]

→ Added a new flashlight control driver which will be used on AOSP/LOS based ROMs. It will also fix low flashlight issue on GSIs. This new driver does not interfere with camera (which was causing dark photos for some A20 users) Footej camera app is recommended for custom roms.

→ Imported latest Samsung updates from A305F R kernel source.

→ "Samsung A10 1.2A input charging current" feature still depends on Eureka dtbo. Will fix it on next update

→ Further overclocked BIG cores from 2184 MHz to 2288 MHz and LITTLE cores from 1690 MHz to 1794 MHz.

→ Fixed wrongly set GPU throttling frequencies.

→ Updated WireGuard vpn driver to latest version - v1.0.20210606

→ Some other minor optimizations.

Eureka R7.0 (R) for A Series

-> Same changelog as 7.0 (Q/R) release. This version is only for roms using R vendor. For the time being, only oneui 3.x uses such vendor.

-> Eureka Defender has not been activated because of some users denying that feature

-> Fixed double tap to wake for some devices using custom ROMs

-> Fixed low torch/flashlight brightness on custom ROMs (dtbo based)

-> Increased A10 input charging current upto 1.2 A (dtbo based)

-> Updated TFA98xx audio codec driver from 4.2.0 to 6.7.8 (latest) - Used by A20, A20e, A30, A30s and A40

-> You can manually turn off cores to save power but at the cost of performance.

-> Custom dtbos/spectrums are/will be available for customizing the kernel to your needs.

-> There will be only 2 kernels as from now, namely enforcing or permissive. Works on custom roms, gsi and oneui based roms.

Eureka R6.5 for A Series

-> Further overclocked BIG cores from 2080 MHz to 2184 MHz.

-> Undervolted the whole soc (exynos 7885) including CPU and GPU.

-> Tweaked kernel for stability and less battery drain at high frequencies.

-> Automatic detection of root when flashing kernel. If you are already rooted, you won't lose root when
flashing kernel as from now. So, no need to flash magisk after kernel!!

-> Added powersuspend driver v1.8 - saves battery when screen is off.

-> Removed/disabled some more useless debugging codes and Samsung securities.

-> Added an improved version of KSM known as UKSM (Ultra Kernel Samepage Merging) - Decreases ram usage

-> Fixed issue of bootloop!! - No more stucking on bootlogo.

-> Slight improvement in boot speed.

-> Built kernel with latest Proton Clang 13 and LTO for better performance.

-> Optional spectrum support - Flash enable_spectrum_support.zip on your internal storage to enable spectrum.

-> Fixed random reboot on android 11 GSIs. If you still get reboots, then the issue is with the GSI. Please
contact the maintainer of the GSI for any fix. Tested Superior GSI android 11 and got no reboot.

Eureka R5.0 for A Series

-> Attempt to fix drivedroid support

-> Fingerprint wake up boost (for supported devices)
