[REFERENCE] ELS - exynos-linux-stable (4.9.193)

[farovitus]

Project: Exynos-Linux-Stable​

- Exynos-Linux-Stable is an organisation on GitLab & GitHub containing upstreamed linux for some of the latest flagship handset from SAMSUNG like the S7, S7E, S8, S8+, Note 8, S9, S9+, Note 9 kernel upstreamed to be inline with respective linux branches.

What does this bring?
- All of the devices mentioned above uses Long Term Support (LTS) releases, they are like old softwares.
- LTS releases are supported through their specified support duration by security updates, bug fixes, backports, and new device drivers, just like a regular release.
So updating or up-streaming your device's kernel brings many improvements talking security, performance wise etc...

How do I use?

If you are a developer, the reference tree is located in the exynos-linux-stable organization: https://github.com/exynos-linux-stable

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, ask your kernel developer KINDLY to use this source for his kernel that has all the changes added in!

No, i am quiet busy these days. Send me a link of your source so i can check it out from my phone.

Again, i am sure the ELS source will compile just fine.

I made zero changes, what I posted is exactly what I did, it does not compile.

Edit: what OS are you compiling on?

that now builds for me.. in the exact same environment, Ubuntu 14.04 in vagrant with a script:

#!/bin/sh
set -e

sudo apt-get update
sudo apt-get install -y git build-essential bc

cd $HOME

[ -d aarch64-linux-android-4.9-kernel ] || git clone --depth=1 https://bitbucket.org/UBERTC/aarch64-linux-android-4.9-kernel
[ -d crownlte ] || git clone --depth=1 https://github.com/exynos-linux-stable/crownlte

export ARCH=arm64 CROSS_COMPILE=aarch64-linux-android- PATH=$HOME/aarch64-linux-android-4.9-kernel/bin:$PATH

cd crownlte
make exynos9810-crownlte_defconfig
make -j8

Don't ask here.. Just take a Rom like ketan and flash only kernel via aroma. Done

Ketan p06 has CSB3 base so that kernel will work no problem.

I know it's a stupid question but how to pack kernel inside IMG? I want to get image for heimdall.
I've honestly googled but it looks like everybody just knows how to do this. And nobody discuss it

You'll want to use Android Image Kitchen to unpack and repack kernels inside images. You can diff the unpacked boot.img provided in devbase with mine to see the basic ramdisk modifications to prevent forced encryption or various other issues. Or you can just unpack my image, it's relatively basic with it's modifications. Hope this helps.

EDIT: You can also look at my make9810.sh script on GitHub to see the various steps I take for repacking my images.

Can someone explain what this is for? Is this purely for use with linux on DEX or are you guys flashing linux direct to your Note9 somehow? Or updating the kernel that android is running on?

It's a reference kernel source with all recent patches from vanilla kernel applied to Samsung stock one. Some developers use this source as a base for their custom kernels. This is what it's for.

ELS is for Android. But I'm developing a kernel that can boot Linux (GNU/Linux) on Note9. And yes, it's based on ELS sources.
