Snapdragon 845 & Mainline Kernel 4.18 and later & Android - LineageOS Questions & Answers

The Snapdragon 845 source code got released and its hardware support starts with the Mainline Kernel 4.18 and will got better.
So my question is:
Will LineageOS or Treble AOSP will use the mainline kernel to power Snapdragon 845 devices?
And when not, why not?
Thank you!

I am also interested in knowing if kernel 4.18 will be pushed with android P release because of the improvements in the schedutil governor should bring better performance and more fluid UI, i am running OnePlus 6 with kernel 4.9 and schedutil governor is extremely smooth but i am still hoping for the iOS like smoothness of iphones with the new improvements in 4.18

The chance of getting 4.18 is low.
4.14 is the latest ltd kernel.
4.19 will be the next one.
Also the kernel need to be chosen by the device maintainer.
The treble lineageos/also image doesn't contain the boot.img with the kernel.
Only the system.img.

Not as of yet. Keep track of the Threads in Android Development & Original Android Development. It will be quite obvious when a custom kernel gets released..which it should...Eventually...........

I don't know about other projects, but I have no intention of pulling in kernel.org upstream on omni.
Why? All of the patches are for hardware that doesn't exist in our phone and rarely have any benefit and in some cases cause regressions. (For example, on the Galaxy S2, pulling in upstream kernel patches would hide some forms of Android OS usage from battery stats - so if your wifi chip went nuts with IRQ spam you wouldn't notice a thing.) In addition, patches that ARE relevant have a bad habit of causing conflicts with CodeAurora pulls. (I do periodically do CAF upstream merges from the kk_3.5 branch)

How Lineage OS build is possible without the kernel?

I'm quite new to Snapdragon SoC's and coming from a MediaTek one, having some trouble to understand the concept of kernel in Lineage OS build.
ASAIK, Mi6 isn't a supported device (yet )
As Xiaomi also hasn't released the kernel source, how is the unofficial Lineage OS build made?
Also from where @xiaobai112220 got this kernel source?

Thanks for any help in this regard.
i think its a "generic"

No, Xiaomi released the kernel sources for Mi6 few days ago.

Question S22 (exynos) kernel version

I'm trying to understand how Samsung manages the kernel, the first question that arises is why my kernel version is 5.10.66, shouldn't it follow the corresponding Linux LTS branch? I tried to download the source code of the s22 kernel that samsung makes available and although they are from the october build looking at the code there is some missing patches that the official android kernel branches patched months earlier. could someone help me clarify, I thought that with the advent of GKI (generic kernel image) Samsung used an official kernel image, maybe just adding some proprietary drivers
