Kernel version in OP3 - OnePlus 3 Questions & Answers

Hi Community,
I was wondering why my custom rom have 3.18 Kernel version - Basic answer seems to be quite obvious dev decided - but I didnt found any information about availability of Kernel 4.xx on this device. What is stoping anyone from compiling "latest" kernel version? What is this missing piece?

According to https://android.stackexchange.com/questions/51651/which-android-runs-which-linux-kernel this is the list of Linux kernel versions used by each AOSP version:
Android Version API Level Linux Kernel in AOSP
----------------------------------------------------
1.5 Cupcake 3 2.6.27
1.6 Donut 4 2.6.29
2.0/1 Eclair 5-7 2.6.29
2.2.x Froyo 8 2.6.32
2.3.x Gingerbread 9, 10 2.6.35
3.x.x Honeycomb 11-13 2.6.36
4.0.x Ice Cream San 14, 15 3.0.1
4.1.x Jelly Bean 16 3.0.31
4.2.x Jelly Bean 17 3.4.0
4.3 Jelly Bean 18 3.4.39
4.4 Kit Kat 19, 20 3.10
5.x Lollipop 21, 22 3.16.1
6.0 Marshmallow 23 3.18.10
7.0 Nougat 24 4.4.1
7.1 Nougat 25 4.4.1
8.0 Oreo 26 4.10
Could be that your rom is based on Marshmallow, or, as you have suggested yourself, that the dev decided to use 3.18

I'm not Linux pro user however there was some quite easy way to export current kernel config. With such config I would be able to compile 4.x kernel and run it without any issues? Or do I need something extra to make it live?
And since I'm on Android 7.1.2 version how it can run on 3.18 kernel without any issues?
And why does Cyanogen/Lineage ROMs have to have some "other" kernel?
I know that there are some firmware files. Are those "universal" / kernel version independent entities? Or those are compatible with 3.18 only and most custom kernels on op3 need to stick to this particular line?

[Q] Any Custom Kernel for Oppo Find 7a Color OS and Custom Android 4.4.3?

Is there any custom kernel for Oppo Find 7a for Android 4.3 and Android 4.4.2? I hope there will be an upstreamed version also (Linux 3.4.91). Thanks

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)

Looking for a ROM for my note 2.

Hi,
I'd like a recommendation for a stable, minimalistic rom which would be battery efficient and work fast, but also up to date with the latest OS - if that's even needed. For example, some mods have the whole "air swipe" abilities, which I don't need. I do however want it to be up to date with the recent android. I researched this a bit and came up with these:
CyanogenModX
ROM OS Version: 5.1.x Lollipop
ROM Kernel: Linux 3.0.x
Benghazi ROM - Advanced Edition
ROM OS Version: 5.1.x Lollipop
ROM Kernel: Linux 3.0.x
SONIC OPEN KANG PROJECT
ROM OS Version: 5.0.x Lollipop
ROM Kernel: Linux 3.4.x
Cyanogenmod 12.1
ROM OS Version: 5.0.x Lollipop
ROM Kernel: Linux 3.0.x
I really like it that Sonic has a newer linux kernel, yet, does it really matter? I know that trying them out would probably give me a better idea of what would work best for me, but I'd appreciate some opiniopns on this.
I too want to know the lightest & most up to date ROM available for the Note 2.
Are the ones posted by AlonP the top 4 ROMS for this device?
The only list online for best roms for the note 2 were from Cnet 3 years ago & is way outdated.

1. It's not based on latest sources. It's based on an very old build of AOKP (from July 2014).
2. No, the Stagefright bug wasn't removed (for more information read Answer #1)
3. It's not ported from any device. It's pure AOKP built by @FrOz3n.

[Q] AOSP 6.0.1 Security Level

Hey there,
i have build a MM rom from AOSP source (https://android.googlesource.com - android-6.0.1_r79).
It shows security patch level 1. February 2017.
The Android Bulletin shows that they updated the 6.0.1 AOSP version frequently (example: https://source.android.com/security/bulletin/2017-06-01 (CVE-2017-0645 A-35385327 EoP Moderate 6.0.1, 7.0, 7.1.1, 7.1.2). The months before also show quite a lot of changes to 6.0.1 but im not sure if they are really merged.
Am i using a wrong repo? Could someone explain that?
Regards
Jojo

Android 11 custom ROMs or kernels?

I'm currently running stock 11 beta, and I know it is a bit early to ask this but does anyone know of any custom kernels that work with Android 11, or any roms based on it?
Android 11 is still in beta, so no source code is available to the public yet. Since there is no source code available to view/download, there will be no custom ROMs, kernels, etc based on Android 11 until the source code is published.
