Build your own kernel under Ubuntu using mainline (latest) kernel

Author:

Here we will show how to build your own kernel under Ubuntu 16/17/18. We are going to use

mainline kernel

because most of the cases when we need to build our own is when we need some new feature presented in the new kernels. So Ubuntu mainline kernels are selected new kernels, which are packed in deb packets for simplicity and can be used to test new features, but they are not supported by Ubuntu teams and you should test them really carefully if you want to use them in production!
The mainline kernels are here: http://kernel.ubuntu.com/~kernel-ppa/mainline/. This is the main address, where you could download the latest kernels and some other legacy one if you have old system.
This howto is based on https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel and https://wiki.ubuntu.com/Kernel/MainlineBuilds – we summarize the commands needed to build your new and latest kernel and show you some typical mistakes and problems during the process.
To show you more information our purpose will be to build the one of the latest kernels with low latency features enabled (Ubuntu has such type of kernel configuration)! And here is one of the most important dependency, which is not explicitly included or even mentioned in most of the tutorials for building your own kernels –

you MUST include new or even latest Linux firmware package

All Linux distros have a package or packages containing files with different firmware for multiple devices supported by the kernel modules. Basically firmware is used by a kernel module and it can be a micro code (program), which is uploaded in the device or just complete the kernel module to function properly with a device. Recent days firmware is like a black box the manufacturer of the devices pack a proprietary code in a firmware blob and the source code is unknown to the community.

The first thing you should do is to choose the kernel version you want to build. We want version 4.17.x as more stable of the latest 4.18, which was released a few days weeks ago (let’s wait for a month after the initial release before using it!).
So the main address is here http://kernel.ubuntu.com/~kernel-ppa/mainline/ and the kernel files, which we are going to use to rebuild are here http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17.19/

There are couple of files.
First are the patch files. You must use these files to patch the kernel source code files. You must download these files.

You can download the deb files and install the kernel 4.17.19 from them if you do not want any changes in it – you can follow our other howto – How to install the latest linux kernel (mainline) in Ubuntu (17.10) distro It is for Ubuntu 17, but the steps are identical for Ubuntu 16 and 18 (and probably for future releases).

So here are the steps to build your own kernel with Ubuntu 16/17/18:

STEP 1) Clone the source code of the kernel 4.17.19

It’ll put the sources in directory v4.17.19. Then you must change the branch to version 4.17.19 (if you are not familiar with git, then just follow the commands below). As you can see the git url is taken from the named “SOURCES” in sub-directory URL for the kernel we’ve chosen http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.17.19/

root@srv:/root/tests/kernel# git clone git://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/mainline-crack v4.17.19

Checking out files: 100% (11040/11040), done.
Note: checking out 'v4.17.19'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

HEAD is now at 62134e7... Linux 4.17.19

After the last command now you have the sources for kernel version 4.17.19 and in the next step will apply all the Ubuntu patches (which also help us to build the kernel as Ubuntu way).
Be careful the unpacked kernel sources consume around 2.8G and you’ll need around 35-40G to compile all the needed packets for our goal. You could just copy the the directory v4.17.19 to somewhere else to have a backup and if you need to start from the beginning no need to wait for the downloading of the sources again.

STEP 2) Download all the Ubuntu patches listed in file SOURCES (you could see them here, too) and apply them to the kernel source of 4.17.19

STEP 3) Build the low latency kernel type from kernel source of 4.17.19

In fact we are going to build all kind of kernels and dependency packages for them like linux-tools, for example, which you do not have if you just use the deb packets from mainline. There are two external dependency libraries SPL and ZFS – you must download them and put them in the sub-directory to the main v4.17.19 – SPL in v4.17.19/spl and v4.17.19/zfs – if you fail to do this the build process will fail. Be careful SPL library is scheduled to merge into ZFS, so things could change slightly.

You could download the SPL/ZFS compressed files (here we use git to get the sources)

STEP 4*) Make changes to the configuration of the kernel sources.

This step could be skipped f you do not need any changes in the kernel config, but if you do, you should go through it.

STEP 5) Build the kernel sources

Multiple deb packages will be generated a directory above the kernel sources v4.17.19.

STEP 6) Install your new kernel v4.17.19.

Put all the deb packets in your repository or if you do not have repo install the deb packets like this: 

root@srv:/root/tests/kernel# dpkg -i linux-headers-4.17.19-041719-lowlatency_4.17.19-041719.201808240919_amd64.deb \

And here we have a problem:

Because of our old linux firmware files. So you must update them with

root@srv:/root/tests/kernel# apt install linux-firmware

The update is from linux-firmware 1.157.13 to linux-firmware 1.157.20.
The initrd.img are repacked with the new firmware files and no errors there, so it should work well after reboot, but after the reboot you shuld check again for firmware errors in dmesg or if some of your devices does not work probably the you need more recent version than there is in the Ubuntu official repos, so you can check here: https://launchpad.net/ubuntu/+source/linux-firmware and/or here: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git The second one is the official repository of the supported firmware files by the Linux kernel. This step is very important, because YOU COULD LOSE your device for example your NETWORKING because of the network driver and after the reboot of your server you’ll have no connection to it!

STEP 7) Now is the time to reboot your server to load the new kernel v4.17.19.

Verify the server is with your new kernel then.

root@srv:/root/tests/kernel# reboot
Connection to srv closed by remote host.
Connection to srv closed.
myuser@local:~$ ssh srv
root@srv ~ # uname -a
Linux srv 4.13.4-041304-lowlatency #201709270931 SMP PREEMPT Wed Nov 1 11:44:52 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
