Kernel necessary for upgrade from Stock-ROM to CM?

Hello,
question like in the title, because some years ago, as I rooted/unlocked my SG II (not plus!) and installed CM, I had to flash a kernel or something. I also had Stock-ROM 4.2.2. Don't remember exactly.
Now I want to install a Custom ROM like CM 12.1 (andixlm) or CM 13 (GHsR), which ones are recommended for more functions and better performance.
If I have to flash a kernel, which one are good ones?
Thank you
Any other useful hints very welcome!
A custom kernel isn't necessary to upgrade from stock rom to custom rom. However there are 2 custom kernel Nebula one (https://forum.xda-developers.com/showthread.php?t=2746991&page=15) and Mosh one (https://forum.xda-developers.com/showthread.php?t=2615010&page=58). I really like the first, because it has a lot of governors, schedulers and features. Lastly CM13 has more feature of CM12, but it's less stable, so choose what you like.

How do custom rom makers make custom rom for different android version?

I heard that custom ROM makers build ROMs on top of a stock ROM and modify it, but how does a custom ROM developer make a custom ROM for Android 6 on an android 4 device where only android 4 is available. At what level is there a difference between the Android versions? Is it at kernel level, Application level?
Suppose I wanted to make an Android 6 custom ROM for and android 4 device, what tools do I use?

Devs that build ROM use directly the Android source code, that every OEM use to build their own OSfor a specific phone.
They can build at any Android version because they don't use the original ROM from the phone, they use AOSP, then modify AOSP to add those sweet features.
The only thing that they use from the phone is its kernel, and OEM post the Kernel's source code on GitHub or another platform to let developers (like ROM devs) work with the phone more deeply.
So to answer your question, Android version are different because features are added and the code modified, every custom ROM for every phone is based on the same Android source code (AOSP). The difference between the phones is at the Kernel level.

Doogee Mix 2

Hello Devs,
I just want to ask is it possible to make custom kernel for this phone so the gsi custom rom,because there is only stock nougat firmware.
The phone is just great with good perfomance but the only lack is nougat.
There is twrp already made so the only problem is to make custom kernel for it.
I would very thankful for helping me with this phone.
I just see lots of "zero" answers here on Android Builders Collective so the chances to make custom kernel and GSI for Doogee mix 2 here are "ZERO".

Kernel Management

Hello I noticed some OP6 devices have different kernels at stock, what kernel should I flash for LOS 18.1? Most of these custom kernels here seem to be strictly for android 10..
Thanks

KVM support in custom kernels possible now that OxygenOS 13 is released?

I'm talking about Kernel Virtual Machine. I couldn't find the supported files in my OOS13 stock ROM after rooting, but is it possible to add support for KVM in a custom kernel for this hardware? What are the potential obstacles kernel developers would have from realizing this goal?
