You can check his work about the dc dimming.
I think this author himself has posted a version of dc dimming kernel before.

Thank you, this looks promising i will take a look at it for future versions

1.6.0 is up. Merry Christmas everyone!

1.7.0 is up! As mentioned in Telegram. I know several users want dc dimming / flicker free dimming added to the Kernel but let me tell you it is not an easy task . It will need several hours invested to port it correctly and i don't have too much spare time nowadays so this specific feature might take a long or will not ever make it to the kernel at all. I apologize but i have other priorities right now .

Enjoy this release, and 1.8.0 will be dropped around new year's eve if everything works fine on my internal testing.

Happy New Year everybody! May you accomplish all of your goals this year and succeed in anything you set for!

As promised, 1.8.0 is up. This is a very interesting update, i have worked both the DEVFREQ and CPU_INPUT BOOST functionalities and fine tuned them for our Device frequencies. You will notice a change in the smoothness of the system overall but i need you to be aware that battery life might be a bit compromised (nothing to be worried about) since now the device will wake up and react to inputs with higher CPU, GPU and DDR frequencies.

I hope this works as intended for everyone but please leave feedback in case anything breaks and as always, if you can... Support the efforts!

Awesome work yet again, been on this update since it dropped and very impressed with smoothness, speed (apps opening and such) and battery hasn't taken a hit (on my device). Great job! Thanks for your work! Very much appreciated.

Thanks for the feedback! I haven't heard from anyone but on my devices it's running smooth as well!

Many Thanks for the Dev.
I tried both VBmeta files after the kernel and still i am stuck at the 2nd Samsung logo. Any suggestions?
S20 Fe 5G latest R

Alright, so after a couple of days with no action over here.... JimboK-2.0.0 has been released. It's an interesting one since i am upstreaming to 4.19.169 and adding some neat features aimed for performance.

So please give it a go and as usual share your feedback when possible

By any chance, does this kernel have USB OTG drivers enabled for Wifi-USB add-ons? I ask because there is not Kali Nethunter development on this phone, and I remember when I tinkered with kernel compilation, that was an very useful feature to have.

Any chance you might consider adding USB OTG functionality (drivers enabled for RTL88XX, ATH9K, ATH10K, etc.)

Thank you.

I can take a look at it. Not full Kali Kernel but those drivers might be able to be compiled as modules

Yes, that's exactly what I was referring to. I would try to compile my own kernel again but honestly your's is great and ... would save me a little time considering that I don't have the toolchain and everything required.. LOL. Need to get back into it.

v2.0 is running great on my C2Q, and honestly the gain is performance and smoothness is far superior to the little battery drain (if any). It's hard to tell at my work about battery life, I rely on WiFi calling throughout the hospital to stay connected and it's a battery killer compared to when I'm home and only connected to one of four access points. But great work Jimbo, very much appreciated!

Hi @jimbo77 thank you for this great kernel!

Can you add dc-dimming feature to this kernel? This feature makes the screen flicker free and improves eye comfort. It's already developed and the sourcecode is on github: https://github.com/DevriesL/Z3Q_ImageBreaker

(the sourcecode is already for s20/s20+/s20u/n20u)

Haven't found by search to keywords like selinux, permissive, enforced
Is this kernel (for Note 20 Ultra) permisive or not?

No it's enforcing. Mentalmuso has one that's permissive tho. It can be found on telegram

Thanks! I know regardin Mentalmuso's kernel. I use it.
But interesting to ry this one as it was updated recently (for Android 10).
@jimbo77 Is it possible to upload permissive versions too?

I am generally against permissive due to the security issues it might bring. Why do you need it to be permissive? If it's a thing most people want/need I might think of changing that

I will take a look. I heard it changes the color scheme too but let me check that out, I will make a test build and see how that looks
