[KERNEL][4.4.302+][for Android 9] A2N Kernel for Galaxy S8/S8+/Note8 (Exynos) [R61]

[canka591]

The kernel is incredibly fast, thanks to the special cooling, I was able to use the small core 2GHz, Big core 2.8 GHz and the GPU at 839 MHz stably.

This kernel provides a extremely fluid experience, but unfortunately I had to revert to this version because my entire setup was on android 10.
I hope one day there will be a version for Android 10 that will at least have enough CPU and GPU overclocking option and we will use it with pleasure.

Below are some test photos for you to compare.

My Set.: Big 2.8 GHz -20mV + Little 2 GHz -20mV + GPU 839 MHz + DVFS Limits are 100 °C

whats on the right corner ? what app is that?

 

[canka591]

whats on the right corner ? what app is that?

Right corner Franco Kernel Manager (fps not work btw), Left corner 3C AiO Toolboox Overlay

 

[ace2nutzer]

For FPS install game plugins from Galaxy Store and then install "Perf Z".

New Kernel and App are Up!

Hi Guys,
I'm very happy to provide to you one more update for this phone.
Probably this is our final build since everything is optimized to the max and it works stable. But like always, "never say never".
Of course if there is some critical security leak that could appear in the future in the Linux/Android kernel that could affect the security of this phone, then it'll be fixed ASAP.


Changelog

A2N Kernel R59

• Re-enabled CONFIG_MEMCG - to reduce memory usage
• LMK/HPA: updated driver for better memory management - by me
• CPU/GPU: updated voltages - increased a bit for stability
• Fixed USB-JIG feature
• SELinux: fake enforcing enabled by default
• LMK: updated minfree values to work more efficient with updated LMK driver
• Init: removed init.d.a2n - instead we use now default init.d folder

A2N Kernel Control V59

• GPU: improved "Gaming Mode"
• RAM: simplified swap control
• CPU/GPU: added ability to check temperature
• Updated defaults & fixed bugs

Flash and enjoy like always!

DOWNLOAD

Edit:
OK guys, new release is fully rolled-out!

For max performance and best gaming/benchmark experience, you can use the following settings:

DVFS max temp for CPU/GPU 100 °C
do CPU/GPU OC or use profile "Performance Plus".
CPU lit/big: enable "Boost"
GPU: enable "Gaming Mode"
RAM: enable "Use Swap" (zRam Size 50 %)

This will be your most fast and smooth experience ever on this phone!

hi i bought this app but my 3dmark and geekbench scores are so low. gb5 and 3dmark points r 1k around. i am using about max and boost settings. i m using w/hades pie 12.0 can u help

Hi!

Could you please post what you have changed in a2n app and also post your bench results as a screenshot.

Hi!

Could you please post what you have changed in a2n app and also post your bench results as a screenshot.

I did tests again after resetting the phone so sorry I'm late.
Max freq 2704
Suspend max 2652
Max tem 90C
A53 max freq 1898
Suspend max 1794
I didnt change voltage settings
Gpu max 764
I didnt change anything
I am satisfied for daily use. surf the internet twitter instagram. etc and I don't have a heating problem. gb5 score is more or less normal but 3d mark is low. what settings do you recommend

 

[ace2nutzer]

The scores are normal according to your settings.

For highest scores, use CPU/GPU max temp 100 °C and enable boost on little and big CPU.

Btw for what you need CPU OC while the screen is off? I suggest to keep at least stock freqs there for better battery life.

Tip:
Before you start a bench, make sure that the phone is not warm to avoid early throttling.

 

[n0te8user]

i suggest this kernel i dont have a cooling system , a little overclock and despite undervoltage reduces the heating problem and provides a serious performance increase. This is gb5 compute test result If I give a concrete example, i play mobile legends sometimes. I can play almost fluently on ultra settings. Many people didn't mention it, but apart from overclocking, adjusting the battery amper is also an extremely good feature. I was very uncomfortable with the charging speed before this kernel.thanks for your good job bro.finally i tried with lots of roms but the best performance i think is stock rom

 

[n0te8user]

i updated app from playstore, do i need to flash the kernel again on twrp?

 

[ace2nutzer]

i updated app from playstore, do i need to flash the kernel again on twrp?

Yes since the app will not update the kernel.
Download latest A2N kernel and flash it over TWRP.
Finally flash Magisk to restore root.

New build is up!

Changelog

A2N Kernel R60

• RAM: Fixed regression from R59 in memory management
• RAM: improved multitasking
• LED-RGB: added a new sysfs interface to force low_powermode_current
• CPUSETS: moved "surfaceflinger", "systemui" and "InfinityWallpaper" to little CPU to save battery

A2N Kernel Control V60

• RAM: optimized zRam routine
• Misc: optimized red LED (ability to force low_powermode_current instead of dynamic_current)
• Updated strings (help text)

 

[n0te8user]

if i change zram size from 75 to 100
page cluster 0 to 3
swappiness 175 to 195

Does it increase or decrease speed?
or is it best settings are default setting?

 

[ace2nutzer]

It'll decrease speed, but more data will fit in RAM. Usually best user experience is with zram size 50 - 75 %.

 

[nicolo777]

I have 2 questions man before try it.
There is a config file that i can edit?
Can this work with android 9 but lineage?

Hi Guys,
even the fact that I'd stated that I'll no longer update this kernel ....
But I couldn't let it be and therefore ....
