openmamba for Raspberry Pi: now with vanilla kernel

The openmamba Raspberry Pi support has been significantly reworked. Raspberry Pi images now use the openmamba vanilla Linux kernel (currently 6.18.x) instead of the Raspberry Pi-patched kernel used previously. This approach ensures timely kernel updates on a par with other architectures and greater consistency with upstream kernel development.

The raspberrypi-firmware package now provides only GPU bootloader files (start*.elf, fixup*.dat, bootcode.bin) and overlays, while the kernel comes from the standard openmamba kernel package for aarch64. Device Tree Blobs (DTBs) for the various Pi models are included directly in the vanilla kernel via the dts/broadcom directory. A new rpi-prepare-boot script handles the preparation of the FAT32 boot partition, automatically assembling the kernel, initramfs (generated by dracut), DTBs and firmware files.

Thanks to the DTBs included in the vanilla kernel, theoretical support now extends to Raspberry Pi 3, 4 and 5 (including Compute Module and Zero 2 variants). Support for Pi 3 and Pi 5 should be considered experimental, and user feedback is very welcome.

Additional improvements: WiFi correctly configured via blacklist and modules-load, udev rule for Bluetooth, CMA memory set to 256 MB in cmdline.txt (required by applications such as Firefox).

Two image variants are available for download from the download page:

• diskimg-raspberrypi rolling (LXQt, aarch64, 2.7 GB — March 23, 2026) — lightweight environment, recommended for Pi 3 and Pi 4 with limited RAM
• diskimg-raspberrypi-plasma rolling (KDE Plasma, aarch64, 3.2 GB — March 24, 2026) — full KDE Plasma environment, recommended for Pi 4 and Pi 5 with 4+ GB of RAM

Minimum requirements: 16 GB SD card. User feedback is particularly welcome for Pi 3 and Pi 5.

openmamba API and internal tools

api.openmamba.org is now available: a new public REST API for querying the openmamba repositories — package search, dependency lookup, changelogs and much more. The OpenAPI 3.0 specification is available at api.openmamba.org/openapi.json. These APIs power the new Packages section on openmamba.org, which now offers more complete and up-to-date browsing and search than before, and support the internal distribution development and management workflows.

The internal build system tools have also been updated: autodist 2.0.5 (new major version), distromatic 3.0.4 (new major version) and autospec 1.44.

Installation Media

Updated openmamba rolling installation media are available. They can be downloaded from the download page.

• livecd rolling (x86_64, 2.6 GB — March 6, 2026) — KDE Plasma desktop with basic software
• livedvd rolling (x86_64, 3.6 GB — March 7, 2026) — KDE Plasma desktop with full software suite
• livecd-light rolling (x86_64 and i586, 2.4/2.1 GB — March 9, 2026) — lightweight LXQt desktop for low-resource systems
• rootfs-base rolling — base system tar.xz archive, available for x86_64, aarch64 and i586

The Docker images on Docker Hub have also been updated for x86_64, aarch64 and i586 architectures.

After a period of packaging and testing openmamba is ready to ship the KDE Plasma 6 mega release upgrade to all users.

The next snapshots of livecd and livedvd live and installation media, which will be available within a couple of days, will already be provided with KDE Plasma 6.

In a few days the KDE Plasma 6 upgrade will be made available also to current installations of the openmamba rolling O.S. since several tests have shown that the upgrade process should be smooth for everybody.

After receiving and applying the upgrade the system needs to be rebooted. In some uncommon cases rebooting using the normal interface from the Plasma menu might not work, if you encounter this problem we suggest to close all running applications and issue a “sudo reboot” command from a terminal window.

Users using the default Plasma session will be automatically switched from X11 to Wayland graphical backend, which is now the default and recommended type of desktop session to use with KDE Plasma and openmamba.

Users can anticipate the upgrade by temporary enabling the “openmamba miscellaneous packages repository [unstable]” in discover Settings.

If you encounter any problem you may use the forum or the other openmamba support channels to ask for help.

Enjoy!

openmamba provides a new web service on the src.openmamba.org site where the recipes (.spec files), patches and additional files representing the over 5500 source packages with which the distribution in format is created and maintained are easily consultable. tracks. The service, based on the Gitea platform, in addition to the RPMs also hosts openmamba’s internal projects.

Other activities completed in 2023:

• the obsolete arm architecture (armel soft-fp) was abandoned to concentrate current and future developments on the two main architectures x86_64 and aarch64; the i586 (x86 32bit) architecture is still maintained in particular to provide the compatibility subsystem for 32-bit applications on installations for x86_64, used for example for Wine and the Steam video games platform;
• last September the migration to a flat root filesystem hierarchy was completed, i.e. eliminating duplicates of the *bin and lib* folders in the root folder (/) and in /usr; this operation has caused some problems in the updates in various phases, however leading to greater maintainability and future stability of the systems successfully updated or installed from scratch after September 2023;
• the constant maintenance and development by the sole maintainer in recent years has brought the distribution to an update level between 85 and 90% (repology) with stability, security and modernity benefits found on the Plasma and LXQt desktop targets;
• the main repository of the rolling distribution has been renamed from devel to base.

In the next future:

• the KDE Plasma environment will need to be updated to be based on Qt6 following the upstream schedule;
• the new package management on src.openmamba.org opens up renewed possibilities for collaborative development also considering that the platform provides functionality for each package for reporting problems, for drafting documentation in Wiki format and for managing Pull Requests; the currently centralized development mechanisms based on the webbuild interface and the autospec and autodist layers could be enhanced using tools such as tito and mock; at the moment there are no precise plans and these developments will depend on any interest and availability found.

Happy 2024 wishes.

Silvan

openmamba is now available for the aarch64 (aka arm64) architecture, which is added to the x86_64, i586 e arm (armel) supported architectures.

This makes openmamba potentially compatible with present and future devices based on 64-bit ARM architecture that have a standard GNU/Linux kernel.

At the same time the openmamba rolling diskimg-raspberrypi for aarch64 image file is available for download, ready to be flashed on a microSD and used with a Raspberry Pi 4 (and technically also with Raspberry Pi 3). The image provides the LXQt desktop environment with support for automatic partition resizing on first boot. Production of the image file that the KDE Plasma environment provides will follow shortly.

Advanced users can use the rootfs-base and rootfs-light for aarch64 images (and soon rootfs) by installing a suitable kernel to run all variants of openmamba on other 64-bit ARM-based devices.

The porting of the applications is still in progress and I invite users to write in the forum in case you need that particular applications are made available for aarch64 with higher priority.

Silvan

The openmamba project officially closes after ten years of life.

Website, services and repositories will continue to be available for an indeterminate period.

The maintainer and founder of the project wishes to thank all the people that in the years have supported and believed in this project.
