Introducing the Automotive Stream Distribution
by Pierre-Yves Chibon 01 Mar '22

01 Mar '22

Good Morning Everyone! When the Automotive SIG was launched last August we knew we wanted to build a place where we could gather inputs and build a community around software for the automotive industry and link these with the Red Hat and CentOS ecosystems. As Red Hat has been working on defining its automotive product, it has become clear that having a public, in development, version of this product would be beneficial. The idea would be to have it seating between the Automotive SIG and the Automotive product. This project has been named: Automotive Stream Distribution It is meant to be to the automotive product what CentOS Stream is to RHEL. Like CentOS Stream, Automotive Stream Distribution will be opened to contributions, using similar mechanisms. On Wednesday March 2nd at 15:00 UTC, we will have our SIG meeting, during which we will discuss the Automotive Stream Distribution as well, so join us there or here! Looking forward to hear your thoughts, Pierre

Weekly update on the automotive-sig
by Pierre-Yves Chibon 25 Feb '22

25 Feb '22

Good Morning Everyone, So here are some of the changes that we have worked on over the last few weeks: * We have worked on some documentation on how to integrate container images while building images. This documentation can be found at: https://sigs.centos.org/automotive/building/containers/ * We have worked with the CentOS infrastructure to allow using the flat dist-git layout in CBS. Announce: https://lists.centos.org/pipermail/centos-devel/2022-February/120223.html * We have started a discussion around the structure of the lookaside used in CentOS: https://lists.centos.org/pipermail/centos-devel/2022-February/120226.html * We have fixed our sample images to use the `kernel-automotive` package instead of the old `kernel-auto` package (oups!). This simple fix, fixes booting a graphical user interface on the raspberry pi 4 * We have refreshed our sample images available at: https://pingou.fedorapeople.org/images/ * We have expanded the documentation available at: https://sigs.centos.org/automotive/ with information about: * The use of content resolver to define the content * How to download the RPMs of interest to the automotive SIG Just a few notes about building images currently: - It looks like CentOS-Stream 9 may have a bug which prevents building image. This is known and being investigated, we'll just have to wait a little. - The rpi4 sample images mentioned above can boot a desktop environment using Wayland if the raspberry pi is configured to use ACPI. If the raspberry pi is configured to use device-tree, Wayland isn't starting correctly. Editing `/etc/gdm/custom.conf` to disable Wayland will make the session start with Xorg, which works fine. - Neptune itself segfaults on launch currently, this is also known and we're looking into it (likely simply needs a rebuild). Happy hacking! Pierre

Good Morning Everyone, First of all, apologies for the silence, it has been two weeks since we sent the last update, we need to get back into this habit :) So here are some of the changes that we have worked on over the last few weeks: * We have done quite a few changes on osbuild to allow building system images with container image pre-installed. This way you can build, say a qcow2 image, boot it in qemu and have `podman images` show you images directly. We can now integrate this with quadlet [1] and as a result have not only a container pre-installed but even automatically started at boot time! If you want to build an image with a container included, ensure you have the latest osbuild package from copr. * We have been working with the CentOS infrastructure to allow using the "flat" dist-git layout when building on CBS (CentOS BuildSystem: https://cbs.centos.org). This should be landing early next week, all tests * having passed in staging! * A few changes have been made to the automotive docs, including the addition on a doc on how to contribute to the automotive-sig repository. * We dropped weak package dependencies from the images built via the automotive-sig repository. This should speed up building the images as well as reduce their size * We have been working on a small project named "remote_builder" which aims is to make it easy for developers to (re)build their source RPM onto multiple hosts (of different architecture). It uses containers as the buildroot/build environment for the source rpm. Its documentation can be found at: https://remote-builder.readthedocs.io/ This is still somewhat work in progress but early developers are more than welcome to give it a try! Happy hacking, Pierre [1] https://github.com/containers/quadlet

Weekly update on the automotive-sig

Actually this is an update for the last two weeks, as there was no update last week. Things that happened last two weeks: * The build pipelines in the manifests dropped a bunch of packages that are not used by the images, such as filesystem support for xfs/squashfs and cdrom support. This makes the build smaller and faster and requires less packages to be supported. * There is a new makefile target extension "*.ext4" which creates an image similar to the normal one but without a multi-partition setup. This is useful on some boards where the boot happens in a non traditional way and all that is needed is the root filesystem. * There is a new makefile target "*.tar" which makes it easy to generate a tarballs containing the contents of what would otherwise be in image. * The makefiles now support passing strings with spaces in them in the DEFINES variable by escaping them with a backslash. * The two images "kernel_dev" and "osbuilder" were combined into a single "developer" image that has the content of the previous as well as some container tooling. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Alexander Larsson Red Hat, Inc alexl(a)redhat.com alexander.larsson(a)gmail.com

Alternative aarch64/arm64 development environments
by Eric Curtin 14 Jan '22

14 Jan '22

Hi Guys, I wrote a blog post describing and comparing Fedora on M1 macOS, Fedora on Android, Fedora on Raspberry Pi and Fedora on x86_64. CentOS runs on these platforms just as well. If curious see below: https://ericcurtin.wordpress.com/2022/01/14/more-than-a-pi-alternative-aarc… Is mise le meas/Regards, Eric Curtin

Good Morning Everyone, First of all, we would like to wish you all a very happy new year! May it give us the opportunity to meet with you all and see our group grow and succeed :) Here is a quick update of some of the things we have been working on this week: * Packaging Some of the libraries we have been using had been quickly packaged and made available in a copr repo. We figured it was time to have another look at them, polish their packaging and submit them to be included in Fedora and EPEL. * A container to (re)building the kernel's RPM We've been looking at ways to build a container with all the dependencies pre-installed to make it really easy to (re)build the kernel's RPM. We ended up with two methods: - One using OSBuild and the Makefile [1] This allows to build qcow2 or container images thus giving the possibility to use VM or container both with the same content - One using a more traditional approach based on a Dockerfile [2] For both approaches, once you are running the container, you can simply: - get a kernel source rpm (for example: https://cbs.centos.org/kojifiles/packages/kernel-auto/5.14.0/30.1.el9s/src/… ) - rpmbuild --rebuild kernel-auto-*.src.rpm Happy hacking, Pierre [1] https://gitlab.com/redhat/automotive/automotive-sig/-/merge_requests/97 [2] Location for that file is still being discussed but we can already make it available on this list if someone is interested/wants it earlier. Just say so :)

Status update on the automotive SIG
by Alexander Larsson 17 Dec '21

17 Dec '21

Things are slowing down now in the project with the holidays coming up, so this might be the last status report in a while, but here are some updates of what happened this week. * Building images in a VM The makefile that builds images now has support (enabled via make VM=1) to run the build in a virtual machine. This has some advantages, First it allows you to run the entire build as a non-privileged user, so no sudo is required, and it doesn't affect the host system. Secondly, it allows you to run the build in a software-emulated non-native architecture VM. For example, you can build an aarch64 image on an x86_64 machine. This is much slower than a native build, but not extremely so. For example, a raspberry pi4 build on my intel desktop takes about 30 minutes. This can be a nice way to e.g. kickstart a raspberry pi image. As part of this change, the makefile rules and the image filenames changed so that they now have the architecture name in them. * Non-UEFI booting raspberry pi images The "direct" version of the images is normally a direct-uefi boot, skipping over grub to be faster. On the raspberry pi however even direct-uefi isn't direct as the firmware is not natively uefi. Instead it was first loading a uefi binary, which then booted the kernel. This is now changed, so that by default (but you can disable it) it boots the kernel directly from the raspberry pi firmware. This makes cold boot times much faster, with boot-to-login going from 2 minutes to 30 seconds. * Neptune image updates There were various updates to the neptune images, which now support both wayland and x11, with new neptune full-screen session options in gdm. * Working on weekly builds We are working on producing weekly builds of the images.. Hopefully we will finish this soon and have the builds publically available, until then there are some manual builds here: https://pingou.fedorapeople.org/images/ * Issues with the raspberry pi images There are some known issues with the kernel graphics drivers in the current images for raspberry pis. The images in the above link should work, but if you build your own from the latest manifests you might run into issues with this graphics not working. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Alexander Larsson Red Hat, Inc alexl(a)redhat.com alexander.larsson(a)gmail.com
