Ubuntu – How/where to clone current 18.04 kernel (5.0.0-37-generic), specifically using Git

18.04clonegitkernel

I am looking to download/clone the source of kernel 5.0.0-37. I am looking to do this exclusively via Git. I know there are other ways to download the source, but I am looking for info on the Git repo that contains the 5.0.0-37 kernel. If anyone knows what it is, can you please share it?

All kernel sources for Ubuntu 18.04 bionic can be found at https://kernel.ubuntu.com/git/ubuntu/ubuntu-bionic.git

The master branch contains the initial 4.15 kernel.

The hwe branch has the latest HWE kernel. It is 5.0 at the moment.

The hwe-edge has the next HWE 5.3 kernel.

There are some other branches that can also be checked out if needed.

You can get the latest HWE kernel by running:

git clone git://kernel.ubuntu.com/ubuntu/ubuntu-bionic.git
cd ubuntu-bionic
git checkout hwe

That will get the current HWE bionic that is the 5.0.0-37 kernel now.

Ubuntu – Download files from Git + GUI

Let me see if I can address how this works.

The contents of the JAR are the repo. It makes no sense from a source control aspect to put the JAR which is the repo in to the repo. If all you want to do is download the JAR then something like this:
```
wget https://github.com/downloads/commonsguy/cwac-wakeful/CWAC-WakefulIntentService.jar
```
would suffice.
You can check for updates at any time with git fetch, you can pull down changes with git pull
Make sure you've installed git-gui package and run git gui from the command line.

Ubuntu – Where to obtain Ubuntu Supplied Third-Party Device Drivers Patches to apply them to vanilla kernels

The Ubuntu kernel doesn't use Debian packaging to apply patches to the kernel source, the way most Debian packages do. In terms of Debian packaging, there's a whole new upstream tarball for each kernel release.

This is done because the Ubuntu kernel team uses git to maintain kernel changes. This aligns us with upstream kernel practices and is more transparent than Debian packaging, for other kernel developers who want to see the (git) patches that make up our kernel.

You can find the Ubuntu git repositories for the kernels here:

http://kernel.ubuntu.com/git

released kernels are found in ubuntu/ubuntu-.git

Instructions for building a kernel are here:

https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel

Use the section for cloning the git repo, and then examine the git logs to find the patches for the driver you want. Then use git to extract them and apply them to your baseline kernel, and build that.
