Introduction
Hello everyone, this is a thread to introduce both users and kernel developers to the concept of linux-stable as well as give developers some tips and a tree to either merge into their own, use as a base, or just as a reference. Feel free to ask questions and enjoy!
What is it?
linux-stable is, as the name implies, the stable branch of the Linux kernel, the base of Android. The phone could not run without the Linux kernel (at least not without reworking a lot of stuff). The Android kernels are based on the longterm stable trees:
Longterm
There are usually several "longterm maintenance" kernel releases provided for the purposes of backporting bugfixes for older kernel trees. Only important bugfixes are applied to such kernels and they don't usually see very frequent releases, especially for older trees.

All Linux development happens on the master branch, which is governed by Linus Torvalds. When issues are discovered there, the fixes are applied then backported to these various stable trees for consumption. It is not uncommon for a fix to need to go back a few years.
There is a LOT more information available in the notes repo in the android-linux-stable organization if you care to learn more in-depth: https://github.com/android-linux-stable/notes
What does this mean for me?
If you are a developer, this means you should be merging these changes into your own tree. These are vetted, stable fixes to real world problems and they are being handed out for free. It does not take long to get up to date (as you can just merge this tree directly into your own or do it yourself using the tree as a reference) and once you are up to date, there is usually a release once every two weeks, give or take. I provide a rebuttal to a lot of various complaints here. If you still feel like there is a good reason not to do this, please let me know, I'll be happy to try and debate on it!
If you are a user, it means that you should be looking for and using kernels that have these fixes, as it shows the developers care for your security and stability. The current version for this device is 4.4.78 on OOS and 4.4.100 on Lineage while the current version upstream is 4.4.162 so all you need to do is go into Settings > About phone and look at the kernel version to know if you are up to date.
How do I use?
If you are a developer, the reference tree is located in the android-linux-stable organization: https://github.com/android-linux-stable/op5
There are three branches, one for OxygenOS 8.0 stable, one for OyxgenOS 8.1 beta, and one for Lineage 15.1.
This can either be merged into your existing kernel tree if you have one or be used as a fresh base. You do not need my permission to use it nor do you need to give me credit (although it would be appreciated).
If you are a user, use a kernel that has the changes added in!

From what I understand, you're creating a space where you're updating the stock Kernel to the latest Linux tags and creating a clean base that others can develop upon for a consistently updated kernel?
Seems to me like the epitome of a community project and in keeping with the heart behind open source.
Great work Nathan!!!

Exactly correct I have seen others grab my kernel and base their work upon (which I have zero issues with) but I know most do it because I've merged linux-stable as one of my first things. Figured I would make their lives easier (plus doing the conflict resolution summaries helped me validate my own work). I am mulling over posting these to the mailing lists so other mainline Linux developers with these devices can easily test new builds and get the latest fixes without needing to do the work themselves (even if they are fully capable).

If you're doing the work anyway and it's just a simple push to mailing list then might as well. Others can choose whether to use it or not but at least it's there. :good:

This isn't a kernel you flash, this is something for developers to use in their own work. For example, my kernel Flash already has all of this, which you can flash.
Nice. How about GCC error fixes and wifi stack driver in this base?

I toyed with the idea of doing two branches (one for building, one for usability) but decided against it as 1. I want this source to be as plain as possible and 2. It doesn't fully fit with the idea of this project. This purely to help developers get up and running with linux-stable, not a fully fledged custom kernel. I will consider adding the GCC fixes to the usability README though, that could be useful.
You are a true asset to this community!
4.4.103 has been merged in, with conflict notes updated accordingly.
Oh boy oh boy it might be time for a rebase for me
4.4.104 has been merged in, with conflict notes updated accordingly.
I truly apologize to anyone who was tracking the tree because I just force pushed. I decided to update the location and branch name and wanted everything to be consistent. It is now up to date with 4.4.105.
I have updated the OP with the notes and tree location. The new notes are on the staging branch right now, they will be merged into master once everything is finalized.
I'm sorry being out off topic, but can i use this https://github.com/android-linux-stable/msm-3.18 kernel source as base for my soc (msm8937) sir?

Most likely yes. For the future, this thread is geared towards the generic CAF trees (msm-3.18 and msm-4.4). Feel free to ask me anything over there.

4.4.103 has been merged in.
This is my first Nexus / Pixel (VZW Galaxy Nexus I don't count), how soon does Google typically release the kernel source for the DP's? Only after the official software release?
I'm torn between stable + your kernel and DP + stock kernel.

It depends. Longer DPs like the initial release of a new major number (7.0, 8.0, etc) typically get kernel source within a month of the new DP version dropping. Smaller DPs usually don't get source until release (7.1 is the only other small DP that has ever happened so not much history).
:good::good::good:
I dont mean to go too offtopic here, but does that apply to the android source codes too? I meam does it usualy take that long for them to release the sources? I am guessing we still dont have any custom roms because the sources were not released by google yet?
4.4.104 has been merged in, with conflict notes updated accordingly.
The repo location has changed (new link is in the OP).
Additionally, an 8.1 branch has been created. Google went from 4.4.56 to 4.4.88 so the branch was redone to avoid conflicts and go with Google's resolution. The notes have been updated as well. Happy kerneling!
4.4.106 has been merged in (conflict notes).

4.4.110 has been merged in (conflict notes).
4.4.111 has been merged in.
Just as a heads up, I started school on Monday so while the updates will still continue, they may not be as timely as they have in the past, especially if there are conflicts that I need to document.
4.4.112 has been merged in (conflict notes).
I used this conflict in my video talking about thinking through linux-stable conflicts, check it out! https://www.youtube.com/watch?v=yWvU8_0O66A

This is just a side project, I may or may not maintain it in future.
A huge thanks to @kdrag0n for the amazing rom and the work done on this rom.

I was just thinking how much I'd love to see this for the 3a.
Couple of things though;
1) Where's the device tree source and vendor blobs?
2) Its unfortunate that you baked in the google crap, one of the great things about custom builds is to get rid of that.

1. Soon I'll push source
2. I do have microg build for sargo as it is my main device, but not for bonito, so I did not post here on xda, if you want it join the support link group in the thread. Regarding google crap, for some users flashing gapps externally had less fluid experience so I did it.
I hope soon will be very soon, since I'm only interested in building myself anyway.
Have you spoken to @kdrag0n about adding in your source and making this "official"?

Vendor Source
Note:- I have few extra proprietary stuff added in vendor for Google Fi and stuff to work for users out the box which lineage does not have added in their vendor, so if you really want less vendor blob use lineage vendor. It will work without any issue, I think kdrag0n also uses them.
Regarding official builds, I don't have the same infrastructure as him(reason why I only posted gapps build here, it takes lot of time to maintain both gapps and non gapps build) nor the time to maintain it officially. as said in thread, this is my side project which I thought to share it with community. If things work well in future and I feel like doing it official, I may ask kdrag0n. Also idk if he is accepting new device as he is maintaining all the official devices alone by himself.

Here's a current source.
I don't know if it's trusted, or who the maintainer of this unofficial build is though. Just found it via telegram.

Nice one. It's really handy to be able to revive old, unsupported devices like the Pixel 3a, which is a perfectly usable phone and can be picked up for next to nothing.
Some of us don't care about de-googling our phones and really just want to extend their lifespan with security updates, so having gapps baked in to ProtonOASP is really nice. Especially when we're just trying to help out our non-technical friends get a bit more life out of their old phones. A consistent, familiar user experience is all they really want.
I was wondering though: Does your build (or any build of ProtonOASP) come with verified-boot signatures so that the device's bootloader can be locked down after the ROM is installed, or is CalyxOS the only option for this?
Unfortunately, Calyx are very puritanical when it comes to de-googling, and microG is just a terrible substitute for interacting with Google services. I tried it on the Pixel 3a, and it doesn't even sync the contact list from your Google account. My non-technical friend was not impressed.
GrapheneOS still has builds up for 3a, however new builds were terminated as of February. While it doesn't ship with gCrap preinstalled, installation is trivial as they've built a compatibility layer to make it work correctly (and much MUCH more securely) as user-installed software, which you can install from the program "Apps".
I want custom rom download
You have to wait for Realme to release kernel sources first
does anyone know how long they wait until they publish a new kernel and is there a way to speed that up? Their github seems to be updated constantly, just not with this kernel
Looks like they've created a new repo for this phone, however there's nothing there yet...

do you know if any rom will be made? will anyone take it?
I hope someone makes a custom rom, chances are low tho, since this community is not very active
It seems that someone Is developing a LineageOS 20 ROM for RMX3242.

If memory serves me right, the MI5 and Zuk 2 where used for porting but it never worked. I think it was about some blobs, GNSS, USB, VoLTE radio. LOS tried to add stuff but that to revert back.
TLDR, the SD820 was a problematic chip as nothing could be ported.
